Much in the same line, it has been pointed out that the decisions based on the analysis of big data are inevitably "informed by the world as it was in the past, or, at best, as it currently is". Fed by a large number of data on past experiences, algorithms can predict future development if the future is similar to the past. If the system's dynamics of the future change (if it is not a stationary process), the past can say little about the future. In order to make predictions in changing environments, it would be necessary to have a thorough understanding of the systems dynamic, which requires theory. As a response to this critique Alemany Oliver and Vayre suggest to use "abductive reasoning as a first step in the research process in order to bring context to consumers' digital traces and make new theories emerge".

Maven addresses two aspects of building software: how software is built and its dependencies. Unlike earlier tools like Apache Ant, it uses conventions for the build procedure. Only exceptions need to be specified. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging. Maven dynamically downloads Java libraries and Maven plug-ins from one or more repositories such as the Maven 2 Central Repository, and stores them in a local cache. This local cache of downloaded artifacts can also be updated with artifacts created by local projects. Public repositories can also be updated.

The diagnosis is based on a clinical presentation, molecular analysis, electropherogram and radiograph. This disease is diagnosed within the first few years of life. Identification of the main characteristics is the key factor in diagnosis. Molecular analysis is used to examine the DNA of the affected person and their parents. For this, a blood sample is needed and the DNA will be extracted with an automatic DNA extractor. The results will show the mutated chromosome and identify if this chromosome was passed on from a parent. A radiograph will show abnormal growth plates and misshapen bones in the limbs. This can confirm the abnormal development and premature fusion of the regions where the diaphyses, of certain long bones, meet their epiphyses. Electropherogram is used to identify genotyping. These results can be used to compare to a normal sequence and relatives sequences.

The Sea Cobra was involved in multiple major operations during the latter half of the twentieth century, such as during the United States invasion of Grenada in 1983. During the Iran–Iraq War of the 1980s, Iranian Sea Cobras were intensely used, proving itself to be capable in both anti-armor and anti-aircraft warfare. Turkey, who operated numerous Cobras and Super Cobras, used the type on multiple occasions against Kurdistan Workers' Party (PKK) insurgents. On numerous occasions in the 1990s, USMC AH-1s were deployed during the Gulf War of the early 1990s, as well as for the United States invasion of Haiti in 1994, and the US intervention in the Yugoslav Wars in the late 1990s. In the twenty-first century, the type also saw action in the multi-decade War in Afghanistan, and the 2003 invasion of Iraq. During October 2020, the USMC withdrew the last of its AH-1Ws in favour of exclusively operating the AH-1Z.

Slevin moved to Carmel ca. 1903 where he and his wife and two children lived in their home on Carmelo Street between Sixth and Ocean Avenues. That same year, they bought a lot for $325 () on Ocean Avenue between Dolores and Lincoln Streets, where Slevin built a general merchandise store in March 1904. The wood-framed Western false-front style store included artists' materials, stationary, magazines, Kodak cameras, photographic supplies, and fishing tackle. From 1904 to 1915, he was Carmel's first postmaster and express agent. He had lock boxes for mail that those on horseback could "ride up, insert their key into a locked box, remove their mail and ride off." He was one of the earliest registered voters in Carmel and voted for the Republican Party.

Both enantiomers of fluoxetine bind to the extracellular vestibule on the LeuT protein is such a way that the three fluorine atoms of the methylphenoxy ring bind into the HBP that is formed by Leu25, Gly26, Leu29, Arg30 and Tyr108. The halogens additionally make Van der Waals interaction with Leu29 and Tyr108, where the ("S")-enantiomer additionally binds to Phe253 and makes Van der Waals contact with it among with previously mentioned amino acids. Because of the ("S")-enantiomers opposite chirality to the ("R")-enantiomer the rest of the molecule is reversed in the HBP, where the amine tail points towards the extracellular space and interacts with the "N"-terminal of Leu400, Asp401 and Ala319 (amino acids which are a part of the TM10). In this LeuT bound form the complex is rather rigid. The methylphenoxy ring rotates about the O5-C6 bond by 46 degrees for the ("R")-enantiomer and 16 degrees for the ("S")-enantiomer, but rigidity in the molecular structure indicates that the drug maintains its low-energy configuration upon binding to its protein target.

The cline of admixture between the ANI and ASI lineages is dated to the period of c. 4.2–1.9 kya by Moorjani et al. (2013), corresponding to the Indian Bronze Age, and associated by the authors with the process of deurbanisation of the Indus Valley civilization and the population shift to the Gangetic system in the incipient Indian Iron Age. Basu et al. (2003) suggests that "Dravidian speakers were possibly widespread throughout India before the arrival of the Indo-European-speaking nomads" and that "formation of populations by fission that resulted in founder and drift effects have left their imprints on the genetic structures of contemporary populations". The geneticist PP Majumder (2010) has recently argued that the findings of Reich et al. (2009) are in remarkable concordance with previous research using mtDNA and Y-DNA:

The event was an outdoor target archery event using recurve bows. Held under the World Archery-approved rules, archers shot at a 122 cm-wide target from a distance of 70 metres, each arrow being awarded between one and ten points depending on how close it landed to the centre of the target. The competition consisted of three stages: an initial ranking round, five elimination rounds, and two finals matches deciding the medal placings. In the ranking round, each of the 48 archers entering the competition shot a total of 72 arrows. The total score of each archer was used to seed the archers into the following five-round single-elimination tournament, the highest-scoring archer receiving the number one seed. If two or more archers finished with the same total score, the number of arrows shot in the central 10-ring on the target was used as a tie-breaker. If two or more archers were still tied, then the number of arrows shot within the inner-10 ring determined the finishing positions.

The development began in 2009 and was inspired by the edition project "Keilschrifttexte aus Assur literarischen Inhalts" (KAL, cuneiform texts with literary content) of the Heidelberg Academy of Sciences and Humanities. In parallel it was applied within the Austrian Corpus Vasorum Antiquorum of the Austrian Academy of Sciences for documentation of red-figure pottery. Current projects are funded by the DFG and the BMBF for contextualization and analysis of seals and sealings of the Corpus der minoischen und mykenischen Siegel, where Thin Plate Splines are used for comparing sealings. Analog to the developments for processing cuneiform tablets there are further approaches for adaption of the combined Computer Vision and Machine Learning methods for other "Scripts in 3D". An example is the application within the Text Database and Dictionary of Classic Mayan.

Heat had been the problem on prior spacewalks, which occurred in sunlight. Hubble needed to be repaired out of sunlight. Musgrave discovered during vacuum training, seven months before the mission, that spacesuit gloves did not sufficiently protect against the cold of space. After STS-57 confirmed the issue in orbit, NASA quickly changed equipment, procedures, and flight plan. Seven total mission simulations occurred before launch, the most thorough preparation in shuttle history. No complete Hubble mockup existed, so the astronauts studied many separate models (including one at the Smithsonian) and mentally combined their varying and contradictory details.

"Wittelsbach", "Wettin", "Mecklenburg", and "Zähringen" served in I Squadron for the duration of their peacetime careers, where they were primarily occupied with training exercises and cruises abroad. "Schwaben" was used as a training ship to modernize the training unit of the German fleet. By 1910, with the arrival of the first dreadnought battleships, the "Wittelsbach"-class ships were removed from front-line service and relegated to training duties or simply laid up in reserve. With the outbreak of World War I in July 1914, the ships returned to active service as IV Battle Squadron, seeing guard duty in the North Sea and limited operations in the Baltic Sea against Russian forces. These operations included supporting the attack on Libau in May 1915 and the Battle of the Gulf of Riga in August that year.

The pollutant species "black carbon" appears gray or black due to the absorption of electromagnetic energy by partially mobile electrons in the graphitic microstructure of the black carbon particles. This absorption is purely ‘resistive’ and displays no resonant bands: consequently, the material appears gray rather than colored. The attenuation of light transmitted through a deposit of these particles increases linearly with the frequency of the electromagnetic radiation, i.e. inversely with respect to wavelength. Aethalometer measurements of optical attenuation on a filter deposit will increase at shorter wavelengths as λ where the parameter α (the Angstrom exponent) has the value α = 1 for ‘gray’ or ‘black’ materials. However, other species may be co-mingled with the black carbon particles. Aromatic organic compounds associated with tobacco smoke and biomass smoke from wood-burning are known to have increased optical absorption at shorter wavelengths in the yellow, blue and near-ultraviolet portions of the spectrum.

Developing computational tools for identification of cell populations has been an area of active research only since 2008. Many individual clustering approaches have recently been developed, including model-based algorithms (e.g., flowClust and FLAME), density based algorithms (e.g. FLOCK and SWIFT, graph-based approaches (e.g. SamSPECTRAL) and most recently, hybrids of several approaches (flowMeans and flowPeaks). These algorithms are different in terms of memory and time complexity, their software requirements, their ability to automatically determine the required number of cell populations, and their sensitivity and specificity. The FlowCAP (Flow Cytometry: Critical Assessment of Population Identification Methods) project, with active participation from most academic groups with research efforts in the area, is providing a way to objectively cross-compare state-of-the-art automated analysis approaches.

In 1989, RISC OS was provided with the Paint application on one of the accompanying application discs. It featured a multi-document, desktop-based interface with a range of elementary painting and drawing tools, also allowing images to be created in arbitrary sizes for any of the display modes, even permitting editing of images in display modes with different numbers of colours, albeit with limitations in the representation of image colours when the desktop mode had fewer colours available. Along with its companion applications, Paint supported the system's anti-aliased fonts and printer driver framework, and by embracing the system's user interface conventions, images could be exported directly to applications such as Draw by dragging an image's file icon from the save dialogue directly to the target application.

During her years at the Children's Hospital of Michigan, Dr. Canady also continued research with Wayne State University. She served as a Professor of Neurosurgery there as well. Her work and accomplishments have opened the door for many surgeons of all races and genders. From 2001 to her retirement in 2012, Dr. Canady worked as a part-time surgeon and consultant at Sacred Heart Hospital in Pensacola, Fl. After moving to Pensacola, Dr. Canady initially considered herself retired. However, after meeting local doctors and realizing the need for a pediatric neurosurgeon in the area, Dr. Canady decided to join the staff at Sacred Heart Hospital, working part-time. In addition to her career as a surgeon, Dr. Canady continued to do research with Wayne State University. This research would eventually lead to the development of an antisiphon shunt that helps to treat hydrocephalus. In a recent interview on why she thinks students should choose neurosurgery she states, "It's intellectually challenging, you get kind of a high when everybody says 'ah, the neurosurgeon is here'". Dr. Canady continues to be both an advocate for her profession as well as diversity in medicine.

Aside from their use in medicine, man-made fluorinated compounds have also played a role in several noteworthy environmental concerns. Chlorofluorocarbons (CFCs), once major components of numerous commercial aerosol products, have proven damaging to Earth's ozone layer and resulted in the wide-reaching Montreal Protocol; though in truth the chlorine in CFCs is the destructive actor, fluorine is an important part of these molecules because it makes them very stable and long-lived. Similarly, the stability of many organofluorine compounds has raised the issue of biopersistence. Long-lived molecules from waterproofing sprays, for example PFOA and PFOS, are found worldwide in the tissues of wildlife and humans, including newborn children.

Hybrid power trains use diesel-electric or turbo-electric to power railway locomotives, buses, heavy goods vehicles, mobile hydraulic machinery, and ships. A diesel/turbine engine drives an electric generator or hydraulic pump, which powers electric/hydraulic motors—strictly an electric/hydraulic transmission (not a hybrid), unless it can accept power from outside. With large vehicles, conversion losses decrease and the advantages in distributing power through wires or pipes rather than mechanical elements become more prominent, especially when powering multiple drives—e.g. driven wheels or propellers. Until recently most heavy vehicles had little secondary energy storage, e.g. batteries/hydraulic accumulators—excepting non-nuclear submarines, one of the oldest production hybrids, running on diesel while surfaced and batteries when submerged. Both series and parallel setups were used in World War II-era submarines.

Each of these points alone can give rise to false results. Due to the combined effects of all error sources yeast two-hybrid have to be interpreted with caution. The probability of generating false positives means that all interactions should be confirmed by a high confidence assay, for example co-immunoprecipitation of the endogenous proteins, which is difficult for large scale protein–protein interaction data. Alternatively, Y2H data can be verified using multiple Y2H variants or bioinformatics techniques. The latter test whether interacting proteins are expressed at the same time, share some common features (such as gene ontology annotations or certain network topologies), have homologous interactions in other species.

Although the genus was considered to be a tomistomine gavialoid or even a direct descendant of "Eogavialis" by early research due to its elongated skull, later research has repeatedly shown this to be merely be the result of convergent evolution, instead placing it much deeper within the Crocodylidae. For instance, "Euthecodon" differs from gavialids and most tomistomines in its small supratemporal fossae and the relatively gradual narrowing of the rostrum (something much more abrupt in gharials). Most current analyses place it in Osteolaeminae, a family consisting of the extant dwarf crocodile and the extinct "Rimasuchus", "Brochuchus" as well as possible "Voay" and the slender-snouted crocodile. Phylogenetic analysis utilizing molecular (DNA sequencing), stratigraphic (fossil age) and morphological data recovers Osteolaeminae, as shown below, with "Mecistops" as a close relative of "Euthecodon". "Voay" was recovered as closer to the genus "Crocodylus".

According to Gangal et al. (2014), there is strong archeological and geographical evidence that neolithic farming spread from the Near East into north-west India. Yet, Jean-Francois Jarrige argues for an independent origin of Mehrgarh. Jarrige notes the similarities between Neolithic sites from eastern Mesopotamia and the western Indus valley, which are evidence of a "cultural continuum" between those sites. Nevertheless, Jarrige concludes that Mehrgarh has an earlier local background," and is not a "'backwater' of the Neolithic culture of the Near East." Singh et al. (2016) investigated the distribution of J2a-M410 and J2b-M102 in South Asia, which "suggested a complex scenario that cannot be explained by a single wave of agricultural expansion from Near East to South Asia," but also note that "regardless of the complexity of dispersal, NW region appears to be the corridor for entry of these haplogroups into India."

The conclusions of his 1971 paper on Central Banks and Economic and Social Welfare programs foreshadowed what is probably his most influential and best known work: "Did Monetary Forces Cause the Great Depression?" (1976). This work hypothesized that it was not primarily the actions of the Federal Reserve in response to the economic downturn of 1930 which turned a recession into the most far reaching slump in the modern economic period, but instead was an autonomous drop in demand. He would later revisit this thesis in his 1989 work "Lessons from the Great Depression", as well as publish several papers building on his conclusions. He joined, in some way, the conclusions of Keynes and Friedman: the Great Depression started with troubles in the 'real economy' later expanded to the financial world via speculation and money destruction (also see the analysis of Rondo Cameron about 'wildcat banking').

There is some supporting evidence from randomized clinical trials (RCTs). A meta-analysis on the effects of alpha-tocopherol supplementation in RCTs on aspects of cardiovascular health reported that when consumed without any other antioxidant nutrient, the relative risk of heart attack was reduced by 18%. The results were not consistent for all of the individual trials incorporated into the meta-analysis. For example, the Physicians' Health Study II did not show any benefit after 400 IU every other day for eight years, for heart attack, stroke, coronary mortality or all-cause mortality. The HOPE/HOPE-TOO trial, which enrolled people with pre-existing vascular disease or diabetes into a multi-year trial of 400 IU/day, reported a higher risk of heart failure in the alpha-tocopherol group.

Towards the end of the twentieth century, the so-called Dinosaur Renaissance took place in which a vast increase in scientific attention was given to the Dinosauria. In 2007, "Jiangjunosaurus" was reported, the first Chinese dinosaur named since 1994. Nevertheless, European and North-American sites have become productive again during the 1990s, "Miragaia" having been found in the Lourinhã Formation in Portugal and a number of relatively complete "Hesperosaurus" skeletons having been excavated in Wyoming. Apart from the fossils per se, important new insights have been gained by applying the method of cladistics, allowing for the first time to exactly calculate stegosaurian evolutionary relationships.

A further key concept in the field of swarm intelligence is stigmergy. Stigmergy is a mechanism of indirect coordination between agents or actions. The principle is that the trace left in the environment by an action stimulates the performance of a next action, by the same or a different agent. In that way, subsequent actions tend to reinforce and build on each other, leading to the spontaneous emergence of coherent, apparently systematic activity. Stigmergy is a form of self-organization. It produces complex, seemingly intelligent structures, without need for any planning, control, or even direct communication between the agents. As such it supports efficient collaboration between extremely simple agents, who lack any memory, intelligence or even awareness of each other.

Experiments were done in 2000–2004 at Flerov Laboratory of Nuclear Reactions in Dubna studying the fission properties of the compound nucleus Fl by bombarding Pu with accelerated Ca ions. A compound nucleus is a loose combination of nucleons that have not yet arranged themselves into nuclear shells. It has no internal structure and is held together only by the collision forces between the two nuclei. Results showed how such nuclei fission mainly by expelling doubly magic or nearly doubly magic fragments such as Ca, Sn, Pb, or Bi. It was also found that Ca and Fe projectiles had a similar yield for the fusion-fission pathway, hence possible future use of Fe projectiles in making superheavy elements. It has also been suggested that a neutron-rich flerovium isotope can be formed by quasifission (partial fusion followed by fission) of a massive nucleus. Recently it has been shown that multi-nucleon transfer reactions in collisions of actinide nuclei (such as uranium and curium) might be used to make neutron-rich superheavy nuclei in the island of stability, though production of neutron-rich nobelium or seaborgium is more likely.

The error would not have rendered his work worthless – each part of Wiles's work was highly significant and innovative by itself, as were the many developments and techniques he had created in the course of his work, and only one part was affected. However without this part proved, there was no actual proof of Fermat's Last Theorem. Wiles spent almost a year trying to repair his proof, initially by himself and then in collaboration with his former student Richard Taylor, without success. By the end of 1993, rumours had spread that under scrutiny, Wiles's proof had failed, but how seriously was not known. Mathematicians were beginning to pressure Wiles to disclose his work whether it was complete or not, so that the wider community could explore and use whatever he had managed to accomplish. But instead of being fixed, the problem, which had originally seemed minor, now seemed very significant, far more serious, and less easy to resolve.

Neil Bartlett was born on 15 September 1932 in Newcastle-upon-Tyne, England. Bartlett's interest in chemistry dated back to an experiment at Heaton Grammar School when he was only eleven years old, in which he prepared "beautiful, well-formed" crystals by reaction of aqueous ammonia with copper sulfate. He explored chemistry by constructing a makeshift lab in his parents' home using chemicals and glassware he purchased from a local supply store. He went on to attend King's College, University of Durham (which went on to become Newcastle University) in the United Kingdom where he obtained a Bachelor of Science (1954) and then a doctorate (1958).

In 1914, the Beckman family moved to Normal, located just north of Bloomington, Illinois, so that the young Beckmans could attend University High School in Normal, a "laboratory school" associated with Illinois State University. In 1915 they moved to Bloomington itself, but continued to attend University High, where Arnold Beckman obtained permission to take university level classes from professor of chemistry Howard W. Adams. While still in high school, Arnold started his own business, "Bloomington Research Laboratories", doing analytic chemistry for the local gas company. He also performed at night as a movie-house pianist, and played with local dance bands. He graduated valedictorian of his class, with an average of 89.41 over four years, the highest attained.

The McKinley National Memorial dedication on September 30, 1907 was one of the most memorable events in Canton's history. President Theodore Roosevelt joined other dignitaries to observe a grand parade from the review stand at Public Square in downtown Canton. In the dedication ceremony, Supreme Court Justice William R. Day, President of the McKinley National Memorial Association and a former member of McKinley's cabinet, delivered a narrative of events leading to the dedication. United States Poet Laureate James Whitcomb Riley read a memorial poem he wrote in honor of the fallen president. Finally, President Roosevelt, the principal speaker of the day, addressed the crowd, highlighting McKinley's career. Mayor of Canton at the time, Arthur Richard Turnbull, also attended along with Ohio Governor Harris. The coffins of the President and First Lady are entombed above ground in double sarcophagi of green granite.

Thorium has been used as a power source on a prototype scale. The earliest thorium-based reactor was built at the Indian Point Energy Center located in Buchanan, New York, United States in 1962. China may be the first to have a shot at commercializing the technology. The country with the largest estimated reserves of thorium in the world is India, which has sparse reserves of uranium. In the 1950s, India targeted achieving energy independence with their three-stage nuclear power programme. In most countries, uranium was relatively abundant and the progress of thorium-based reactors was slow; in the 20th century, three reactors were built in India and twelve elsewhere. Large-scale research was begun in 1996 by the International Atomic Energy Agency to study the use of thorium reactors; a year later, the United States Department of Energy started their research. Alvin Radkowsky of Tel Aviv University in Israel was the head designer of Shippingport Atomic Power Station in Pennsylvania, the first American civilian reactor to breed thorium. He founded a consortium to develop thorium reactors, which included other laboratories: Raytheon Nuclear Inc. and Brookhaven National Laboratory in the United States, and the Kurchatov Institute in Russia.

While using the new Eight-Foot High-Speed Tunnel, a wind tunnel with performance up to Mach 0.95 at NACA's Langley Research Center, he was surprised by the increase in drag due to shock wave formation. Whitcomb realized that, for analytical purposes, an airplane could be reduced to a streamlined body of revolution, elongated as much as possible to mitigate abrupt discontinuities and, hence, equally abrupt drag rise. The shocks could be seen using Schlieren photography, but the reason they were being created at speeds far below the speed of sound, sometimes as low as Mach 0.70, remained a mystery.

The supersonic airliner Concorde had to deal with particularly high pressure differentials because it flew at unusually high altitude (up to ) and maintained a cabin altitude of . Despite this, its cabin altitude was intentionally maintained at . This combination, while providing for increasing comfort, necessitated making Concorde a significantly heavier aircraft, which in turn contributed to the relatively high cost of a flight. Unusually, Concorde was provisioned with smaller cabin windows than most other commercial passenger aircraft in order to slow the rate of decompression in the event of a window seal failing. The high cruising altitude also required the use of high pressure oxygen and demand valves at the emergency masks unlike the continuous-flow masks used in conventional airliners. The FAA, which enforces minimum emergency descent rates for aircraft, determined that, in relation to Concorde's higher operating altitude, the best response to a pressure loss incident would be to perform a rapid descent.

Around 1508, Albrecht Dürer described the function of portraiture as "preserving a person's appearance after his death". Portraits were objects of status, and served to ensure that the individual's personal success was recorded and would endure beyond his lifetime. Most portraits tended to show royalty, the upper nobility or princes of the church. The new affluence in the Burgundian Netherlands brought a wider variety of clientele, as members of the upper middle class could now afford to commission a portrait. As a result, more is known about the appearance and dress of the region's people than at any time since the late Roman period. Portraits did not generally require lengthy sittings; typically a series of preparatory drawings were used to flesh out the final panel. Very few of these drawings survive, a notable exception being for his "Portrait of Cardinal Niccolò Albergati".

Better color separation can be reached by three-CCD devices (3CCD) and a dichroic beam splitter prism, that splits the image into red, green and blue components. Each of the three CCDs is arranged to respond to a particular color. Many professional video camcorders, and some semi-professional camcorders, use this technique, although developments in competing CMOS technology have made CMOS sensors, both with beam-splitters and bayer filters, increasingly popular in high-end video and digital cinema cameras. Another advantage of 3CCD over a Bayer mask device is higher quantum efficiency (higher light sensitivity), because most of the light from the lens enters one of the silicon sensors, while a Bayer mask absorbs a high proportion (more than 2/3) of the light falling on each pixel location.

The Gold Rush stimulated economies around the world as well. Farmers in Chile, Australia, and Hawaii found a huge new market for their food; British manufactured goods were in high demand; clothing and even prefabricated houses arrived from China. The return of large amounts of California gold to pay for these goods raised prices and stimulated investment and the creation of jobs around the world. Australian prospector Edward Hargraves, noting similarities between the geography of California and his home country, returned to Australia to discover gold and spark the Australian gold rushes. Preceding the Gold Rush, the United States was on a bi-metallic standard, but the sudden increase in physical gold supply increased the relative value of physical silver and drove silver money from circulation. The increase in gold supply also created a monetary supply shock.

Many open textbooks are licensed to allow modification. This means that instructors can add, remove or alter the content to better fit a course's needs. Furthermore, the cost of textbooks can in some cases contribute to the quality of instruction when students are not able to purchase required materials. A Florida governmental panel found after substantial consultation with educators, students, and administrators that "there are compelling academic reasons to use open access textbooks such as: improved quality, flexibility and access to resources, interactive and active learning experiences, currency of textbook information, broader professional collaboration, and the use of teaching and learning technology to enhance educational experiences."

The legions after the Marian Reforms were able to form into a close-defensive formation to resist a barrage of arrow fire or an enemy charge. This formation was called the testudo. The Roman Legionary Cohorts continued to use the testudo throughout the remainder of their history until the collapse of the Western Roman Empire. When in battle, the legions would be separated into their respective cohorts. Four of the cohorts would line up on the battle line and lead. The other six would follow behind the first four as reserves should many men fall in battle. If Roman cavalry were involved, they were placed on the sides of the main cohorts. Like the Early Republican armies, the legion cohorts were still organized into the same checkerboard formation. The soldiers marched forward until they met the enemy and proceeded to attack. The initial formation of soldiers was dictated by the enemy's formation, the terrain of the battlefield, and the types of troops which the legion in question was composed of. In order to soften up the enemy before the main infantry, the soldiers threw "pilum"; additionally, they shot arrows if they had archers among them. On occasion, a legion would have "ballista", or a piece of field artillery which threw large arrow-like projectiles which served to inflict casualties, frighten enemies, and disrupt their formations. To instil fear into their enemy, the soldiers of a legion would march onto an enemy completely silent until they were close enough to attack. At that point, the entire army would utter a battle cry to frighten their enemy. When their tactics did not initially work, commanders would often mould their tactics to what was necessary.

The Broadgate Phase 11 - Exchange House in London was one of Iyengar's most innovative structural engineering works. The building is directly over the top of Liverpool Street Station, a high traffic railroad station. But the rail station could not be touched so no supporting column could touch the ground. To solve this problem three different structural systems were used to support the 10 story tall building over the 78 meter clear span. These were an X-braced truss system, a 10 story catenary suspension system, and a parabolic arch system, resulting in a kind of building-bridge hybrid. Completed in 1990, the building was awarded the Twenty-five Year Award by the American Institute of Architects in 2015 as a testament to its "enduring significance."

Netbooks, also called mini notebooks or subnotebooks, were a subgroup of laptops suited for general computing tasks and accessing web-based applications. Initially, the primary defining characteristic of netbooks was the lack of an optical disc drive, smaller size, and lower performance than full-size laptops. By mid-2009 netbooks had been offered to users "free of charge", with an extended service contract purchase of a cellular data plan. Ultrabooks and Chromebooks have since filled the gap left by Netbooks. Unlike the generic Netbook name, Ultrabook and Chromebook are technically both specifications by Intel and Google respectively.

Correct use of language can also be key to identifying or reducing the risks of human error, which are often the root cause of many failures. This can include proper instructions in maintenance manuals, operation manuals, emergency procedures, and others to prevent systematic human errors that may result in system failures. These should be written by trained or experienced technical authors using so-called simplified English or Simplified Technical English, where words and structure are specifically chosen and created so as to reduce ambiguity or risk of confusion (e.g. an "replace the old part" could ambiguously refer to a swapping a worn-out part with a non-worn-out part, or replacing a part with one using a more recent and hopefully improved design).

Richard Dawkins dedicates a chapter in "The Blind Watchmaker" to correcting, in his view, the wide confusion regarding "rates of change". His first point is to argue that phyletic gradualism—understood in the sense that evolution proceeds at a single uniform speed, called "constant speedism" by Dawkins—is a "caricature of Darwinism" and "does not really exist". His second argument, which follows from the first, is that once the caricature of "constant speedism" is dismissed, we are left with one logical alternative, which Dawkins terms "variable speedism". Variable speedism may also be distinguished one of two ways: ""discrete variable" speedism" and ""continuously variable" speedism". Eldredge and Gould, proposing that evolution jumps between stability and relative rapidity, are described as "discrete variable speedists", and "in this respect they are genuinely radical." They assert that evolution generally proceeds in bursts, or not at all. "Continuously variable speedists", on the other hand, advance that "evolutionary rates fluctuate continuously from very fast to very slow and stop, with all intermediates. They see no particular reason to emphasize certain speeds more than others. In particular, stasis, to them, is just an extreme case of ultra-slow evolution. To a punctuationist, there is something very special about stasis."

The "Drosophila" embryonic protein SNAI1, commonly known as Snail, is a zinc finger transcriptional repressor which downregulates the expression of ectodermal genes within the mesoderm. The nuclear protein encoded by this gene is structurally similar to the "Drosophila" Snail protein, and is also thought to be critical for mesoderm formation in the developing embryo. At least two variants of a similar processed pseudogene have been found on chromosome 2. SNAI1 zinc-fingers (ZF) binds to E-box, an E-cadherin promoter region, and represses the expression of the adhesion molecule, which induces the tightly bound epithelial cells to break loose from each other and migrate into the developing embryo to become mesenchymal cells. This process allows for the formation of the mesodermal layer in the developing embryo. Though SNAI1 is shown to repress expression of E-cadherin in epithelial cells, studies have shown homozygous mutant embryos are still able to form a mesodermal layer. However, the mesodermal layer present shows characteristics of epithelial cells and not mesenchymal cells (the mutant mesoderm cells exhibited a polarized state). Other studies show that mutation of specific ZFs contribute to a decrease in SNAI1 E-cadherin repression.

Chickens normally have an anisodactyl toe arrangement, with one short toe pointing backwards and three long toes pointing forwards. In diplopodia, the feet usually lack the normal hind toe and instead develop two to four extra toes at various positions between the hock joint and the front toes. The toes are almost always connected to extra tarso-metatarsal bones, though sometimes the toes do not contain any bone. Embryos with diplopodia have been found with numbers of digits on one wing ranging from one to seven, while normal embryos have three digits per wing. Diplopod limb buds first differ visibly from normal limb buds by their abnormally thick and long apical ectodermal ridges. Diplopodia usually delays the embryonic growth of cartilage, bone, and tendon by two days, particularly in the limbs. Other characteristics frequently seen in diplopodia mutants are shortened wings and legs, short upper beak, and smaller embryo size. Many embryos reach the final embryonic stage but then are unable to hatch, though, diplopod embryos can occasionally hatch and mature.

Bisphosphonates were originally synthesized in the 19th century and used in industry for their antiscaling and anticorrosive properties. In the late 1960s their potential to treat diseases related to the metabolism of the bones became evident. The first generation of bisphosphonates included etidronic acid and clodronic acid which were introduced in the 1970s and 1980s. They were the first bisphosphonate drugs to be used successfully in the clinic. They have since then been developed further with the intention to make them more potent, enhance their distribution inside the bone and extend the duration of action. This has made it possible to give zoledronate, the most recent bisphosphonate drug to be placed on the market, in a single annual dose by intravenous infusion.

A number of peer-reviewed scientific literature exists on the ecophysiology of this algal genus. Natural and cultivated sexually reproducing environmental samples, as well as sexually reproducing and serendipitously discovered asexually reproducing ecotypes of monostromatic green alga from Tosa Bay, Japan are conspecific (belong to the same species). Patterns of seasonal fluctuations in its thallus lengths were habitat specific and recur annually. Both appearance and decay of thalli were earlier at high saline habitats, suggesting that salinity positively influences either maturation of sporophytes or senescence of gametophytes. Results from life cycle, thallus ontogeny, gametangial ontogeny and phylogenetic analyses suggest that this algal genus is evolutionarily affiliated in the order Ulotrichales. Type of life cycle is not a valid diagnostic character for the species circumscription in Monostromataceae

The issues to be decided concerned other Proposition 1A legal requirements: (1) Can the train travel from Los Angeles (Union Station) to San Francisco (Transbay Terminal) in two hours and 40 minutes? (2) Will the train require an operational subsidy? (3) Does the new "blended system" approach meet the definition of high-speed rail in Proposition 1A? On Mar. 8, 2016 Judge Kenny ruled the issues raised were "not ripe for review". The plaintiffs raised compelling questions, but the Authority hasn't yet submitted its funding plan, and the project is still too much in flux. Thus, this case was ended, however, there is a possibility of further action on these issues in the future.

Garivier and Moulines derive some of the first results with respect to bandit problems where the underlying model can change during play. A number of algorithms were presented to deal with this case, including Discounted UCB and Sliding-Window UCB. A similar approach based on Thompson Sampling algorithm is the f-Discounted-Sliding-Window Thompson Sampling (f-dsw TS) proposed by Cavenaghi et al. The f-dsw TS algorithm exploits a discount factor on the reward history and an arm-related sliding window to contrast concept drift in non-stationary environments. Another work by Burtini et al. introduces a weighted least squares Thompson sampling approach (WLS-TS), which proves beneficial in both the known and unknown non-stationary cases. In the known non-stationary case, the authors in produce an alternative solution, a variant of UCB named Adjusted Upper Confidence Bound (A-UCB) which assumes a stochastic model and provide upper-bounds of the regret.

Historically, the vast majority of freight trains on Britain's railways have used diesel propulsion since the 1960s. During the late 2010s, as part of wider efforts to pursue carbon neutral operations, the Department for Transport (DfT) stated its long term goal of eliminating diesel-only traction from Britain's railways by 2040, despite only 46.5 per cent of all lines being electrified. However, due to a lack of government support for the rail freight sector, operators have traditionally faced difficulty in justifying sizable capital investments such as new locomotives, thus large numbers are between 25 and 50 years old as of 2020.

About 50% of people of Northeast Asian descent have a dominant mutation in their acetaldehyde dehydrogenase gene, making this enzyme less effective, which causes the alcohol flush reaction, also known as Asian flush syndrome. A similar mutation is found in about 5–10% of blond-haired blue-eyed people of Northern European descent. In these people, acetaldehyde accumulates after drinking alcohol, leading to symptoms of acetaldehyde poisoning, including the characteristic flushing of the skin and increased heart and respiration rates. Other symptoms can include severe abdominal and urinary tract cramping, hot and cold flashes, profuse sweating, and profound malaise. Individuals with deficient acetaldehyde dehydrogenase activity are far less likely to become alcoholics, but seem to be at a greater risk of liver damage, alcohol-induced asthma, and contracting cancers of the oro-pharynx and esophagus due to acetaldehyde overexposure.

"Inflexible" was the first Royal Navy ship to be completely lit by electricity, and the first to have underwater torpedo tubes. The electrical installation provided 800 volts DC to power arc lamps in the engine and boiler rooms and Swan incandescent bulbs in other parts of the ship. The circuitry was complicated because the lighting consisted of sets of 18 Swan lamps and an arc lamp arranged in series. Each incandescent bulb was fitted with an automatic mechanism to switch in a resistor to maintain continuity should it fail, so that the set of 19 lights would not be extinguished if one failed. The arrangement also led to the first fatal electrocution on a Royal Navy ship, in 1882, after which the Navy adopted an 80 volt standard for its ships.

Henry's drawing machines of the 1960s represent a remarkable innovation in the field of art and technology for a variety of reasons. Firstly, the bombsight analogue computer provided not only the inspiration but also the main tool for producing highly original visual effects (O'Hanrahan 2005). Secondly, his machines' reliance on a mechanics of chance, as opposed to pre-determined computer programmes, ensured the unrepeatable and unique quality of his infinitely varied machine-generated effects or "Machine Pollocks" as Henry called them. (O'Hanrahan 2005). Thirdly, the spontaneous, interactive potential of his drawing machines' modus operandi pre-empted by some twenty years this particular aspect of later computer graphic manipulation software (O'Hanrahan 2005). As a result, The drawing machines and their visual effects represent pioneering precursors to the Digital Art produced by today's computer software.

The Kaiser died on 15 June 1888. The next day a post-mortem examination was performed by Virchow and his assistant. They found that the larynx was extensively damaged by ulceration, and microscopic examination confirmed epidermal carcinoma. "Die Krankheit Kaiser Friedrich des Dritten (The Medical Report of Kaiser Frederick III)" was published on 11 July under the lead authorship of Bergmann. But Virchow and Mackenzie were omitted, and they were particularly criticised for all their works. The arguments between them turned into a century-long controversy, resulting in Virchow being accused of misdiagnosis and malpractice. But reassessment of the diagnostic history revealed that Virchow was right in his findings and decisions. It is now believed that the Kaiser had hybrid verrucous carcinoma, a very rare form of verrucous carcinoma, and that Virchow had no way of correctly identifying it. (The cancer type was correctly identified only in 1948 by Lauren Ackerman.)

With the second configuration enclosed in a lead box, the results showed that some cosmic rays interact in lead to produce multiple secondary particles. In an extension of the second experiment, he measured the rate of triple coincidences as a function of the amount of the lead above the counters. A plot of this rate against thickness, which came to be known as the Rossi curve, showed a rapid rise as the lead layer was increased, followed by a slow decline. These experiments showed that ground-level cosmic rays consist of two components: a "soft" component which is capable of prolific generation of multiple particle events, and a "hard" component which is capable of traversing great thicknesses of lead. At the time, the physical nature of both was a mystery, for they did not yet fit into the growing body of knowledge about nuclear and particle physics.

In the Middle Hills and Himalaya of Nepal, people living above about 2,000 m practise transhumance and nomadic pastoralism because settled agriculture becomes less productive due to steep slopes, cooler temperatures and limited irrigation possibilities. Distances between summer and winter pasture may be short, for example in the vicinity of Pokhara where a valley at about 800 meters elevation is less than 20 km. from alpine pastures just below the Annapurna Himalaya, or distances may be 100 km or more. For example, in Rapti zone some 100 km west of Pokhara the Kham Magar move their herds between winter pastures just north of India and summer pastures on the southern slopes of Dhaulagiri Himalaya. In far western Nepal, ethnic Tibetans living in Dolpo and other valleys north among the high Himalaya moved their herds north to winter on the plains of the upper Brahmaputra basin in Tibet proper, until this practice was prohibited after China took over Tibet in 1950–51.

In the U.S., thousands of civilian UAV operators work for contractors, piloting and maintaining UAVs. Up to four UAVs and about 400 to 500 pilot and ground support personnel are required for a single 24-hour-coverage combat air patrol (CAP). A 2011 study by the Air Force School of Aerospace Medicine indicated that nearly 50% of spy UAV operators suffer from high stress. The president of a civilian UAV operators' union, the Association of Unmanned Operation (AUO), cited long working hours and decreasing wages as U.S. involvement in wars in Iraq and Afghanistan was reduced and as a result of the U.S. government's budget sequestration.

In 1937, Hebb married his second wife, Elizabeth Nichols Donovan. That same year, on a tip from his sister Catherine (herself a PhD student with Babkin at McGill University), he applied to work with Wilder Penfield at the Montreal Neurological Institute. Here he researched the effect of brain surgery and injury on human brain function. He saw that the brain of a child could regain partial or full function when a portion of it is removed but that similar damage in an adult could be far more damaging, even catastrophic. From this, he deduced the prominent role that external stimulation played in the thought processes of adults. In fact, the lack of this stimulation, he showed, caused diminished function and sometimes hallucinations.

Cardiac output increases throughout early pregnancy, and peaks in the third trimester, usually to 30-50% above baseline. Estrogen mediates this rise in cardiac output by increasing the pre-load and stroke volume, mainly via a higher overall blood volume (which increases by 40–50%). The heart rate increases, but generally not above 100 beats/ minute. Total systematic vascular resistance decreases by 20% secondary to the vasodilatory effect of progesterone. Overall, the systolic and diastolic blood pressure drops 10–15 mm Hg in the first trimester and then returns to baseline in the second half of pregnancy. All of these cardiovascular adaptations can lead to common complaints, such as palpitations, decreased exercise tolerance, and dizziness.

Research into deployments of multi-factor authentication schemes has shown that one of the elements that tend to impact the adoption of such systems is the line of business of the organization that deploys the multi-factor authentication system. Examples cited include the U.S. government, which employs an elaborate system of physical tokens (which themselves are backed by robust Public Key Infrastructure), as well as private banks, which tend to prefer multi-factor authentication schemes for their customers that involve more accessible, less expensive means of identity verification, such as an app installed onto a customer-owned smartphone. Despite the variations that exist among available systems that organizations may have to choose from, once a multi-factor authentication system is deployed within an organization, it tends to remain in place, as users invariably acclimate to the presence and use of the system and embrace it over time as a normalized element of their daily process of interaction with their relevant information system.

DirectX included DirectInput from version 1.0 (1995). It initially offered true support only for joysticks, as the mouse and keyboard modules simply provided wrappers to the standard Win32 API. DirectX version 3.0 (1996) added support for keyboards and mice; it also improved joystick support. DirectX 5.0 (1997) included greatly improved joystick support, including adding haptic feedback, increasing the number of buttons, changing the underlying device-driver model and incorporating a COM-based API. Mouse support also increased the number of buttons seen from four to eight. In DirectX 7.0 (1999- ), DirectInput added a long-promised feature of seeing individual mice much like individual joysticks, but the feature didn't work with the later released Windows XP, even though it works with Windows 98/Me and DirectX 9. DirectX 8.0 (2000), the last version with major changes, included action mapping and broader support for different types of devices.

In industrialized nations, thiamine deficiency is a clinically significant problem in individuals with chronic alcoholism or other disorders that interfere with normal ingestion of food. Thiamine deficiency within developed nations tends to manifest as Wernicke–Korsakoff syndrome. Chronic alcoholism can disrupt thiamin absorption and thiamin deficiency contributes to neurodegeneration and memory loss in alcoholics known as Wernicke's encephalopathy. Individuals with chronic alcoholism may fall short on minimum daily requirements of thiamine in part due to anorexia, erratic eating habits, lack of available food, or a combination of any of these factors. Thiamine deficiency has been reported in up to 80% of alcoholic patients due to inadequate nutritional intake, reduced absorption, and impaired utilization of thiamine. Alcohol, in combination with its metabolite acetaldehyde, interacts with thiamine utilization at the molecular level during transport, diphosphorylation, and modification processes. For this reason, chronic alcoholics may have insufficient thiamine for maintenance of normal brain function, even with seemingly adequate dietary intake.

The idea of incorporating an integrated circuit chip onto a plastic card was first introduced by two German engineers in the late 1960s, Helmut Gröttrup and Jürgen Dethloff. In February 1967, Gröttrup filed the patent DE1574074 in West Germany for a tamper-proof identification switch based on a semiconductor device. Its primary use was intended to provide individual copy-protected keys for releasing the tapping process at unmanned gas stations. In September 1968, Helmut Gröttrup, together with Dethloff as an investor, filed further patents for this identification switch, first in Austria and in 1969 as subsequent applications in the United States, Great Britain, West Germany and other countries.

Various aspects of pterosaur biology invited controversy from the beginning. Samuel Thomas von Soemmering ignited a multi-century debate over how pterosaurs walked on the ground by suggesting they crawled on all fours like bats. August Quenstedt, by contrast, argued that they walked on their hind limbs. In the early 20th century, Hankin and Watson in the first major study of pterosaur flight biomechanics concluded that on the ground these reptiles were altogether helpless and could only scoot along on their stomachs like penguins. The debate gained steam in 1957 when William Stokes reported unusual tracks left by a four-footed animal he suspected was a pterosaur walking along the ground. In 1984, Kevin Padian, who had recently argued that pterosaurs walked on their hind legs, dismissed Stokes's tracks as those of a crocodilian. However, in the mid-1990s, Jean-Michel Mazin and others reported that fossil footprints in Crayssac, France were similar to those reported by Stokes from the US. Mazin's tracks were more obviously pterosaurian in origin and settled the debate in favor of pterosaurs walking on all fours.

Since 2008, electrical and computer engineering students from Michigan State University have installed multiterminal systems with internet access in three schools in Mto wa Mbu, Tanzania. The purpose of the project is to study the impact of having computer systems with internet access in an education system that cannot afford other educational resources such as books. The computer systems run Ubuntu 8.04 32-bit and utilize the open source Multiseat Display Manager created by C3SL. The research will eventually be used to present to government officials of third world countries in effort to showcase the positive impact of having cost-effective computing systems in schools. The project is sponsored by George and Vickie Rock and the Dow Chemical Company.

These systems claim symmetric and full duplex communication in excess of 1 Gbit/s in each direction. Multiple Wi-Fi channels with simultaneous analog television in the 2.4 and 5.0 GHz unlicensed bands have been demonstrated operating over a single medium voltage line conductor. Because the underlying propagation mode is extremely broadband (in the technical sense), it can operate anywhere in the 20 MHz20 GHz region. Also since it is not restricted to below 80 MHz, as is the case for high-frequency BPL, these systems can avoid the interference issues associated with use of shared spectrum with other licensed or unlicensed services.

Although it resembles a pachinko machine in its aesthetic use of gravity-fed metal balls, it is primarily a teaching device in the fundamentals of logic-computer programming, and as such is an example of gamification. The framing device in the included comic book features an astronaut who must solve sixty increasingly difficult logic problems which illustrate the fundamentals of computer programming. The impetus of the puzzle itself was the frustration of the programmer and chemistry professor Paul Boswell (along with his wife, Alyssa Boswell, a DIY maker), then at the University of Minnesota, at the lack of computing prowess of other scientists which was necessary for their own projects; he was already well known for programming complex games for Texas Instruments computers. They were also inspired by the Digi-Comp II, a precursor from the late 1960s.

In some countries, like the United States, chiropractors earn a professional doctorate where training is entered after obtaining between 90 and 120 credit hours of university level work (see second entry degree) and in most cases after obtaining a bachelor's degree. The World Health Organization lists three potential educational paths involving full‐time chiropractic education around the globe. This includes: one to four years of pre-requisite training in basic sciences at university level followed by a four-year full‐time doctorate program; DC. A five-year integrated bachelor degree; BSc (Chiro). A two-to-three-year master's degree following the completion of a bachelor's degree leads to the MSc (Chiro). In South Africa the Masters of Technology in Chiropractic (M.Tech. Chiro) is granted following six years of university.

One of the most popular of the many versions of Tiny BASIC was Palo Alto Tiny BASIC, or PATB for short, by Li-Chen Wang. PATB first appeared in the May 1976 edition of "Dr. Dobbs", written in a custom assembler language with non-standard mnemonics. This led to further ports that worked with conventional assemblers on the 8080. The first version of the interpreter occupied 1.77 kilobytes of memory and assumed the use of a Teletype Machine (TTY) for user input/output. An erratum to the original article appeared in the June/July issue of "Dr. Dobb's" (Vol. 1, No 6). This article also included information on adding additional I/O devices, using code for the "VDM" video display by Processor Technology as an example.

A number of methods have been reported to produce carbon nanoscrolls, including arc discharge, high-energy ball milling, and intercalation, among others. Wedge based mechanical exfoliation is also reported to form carbon nanoscrolls experimentally. However, the real world applications of nanoscroll products are limited due to their difficult colloidal processing. Thermodynamically, the nanoscale surfaces are stacking each other via van der Waals force to lower the energy barrier. To overcome this problem and obtain high quality nanoscrolls, a polymer-assisted liquid exfoliation technique has been recently demonstrated, allowing to manufacture high throughput and high quality CNS dispersions. Other material-based nanoscrolls, e.g. gold nanoscrolls, were also successfully attained by the exfoliation technique.

Human languages use many different sounds and in order to compare them linguists must be able to describe sounds in a way that is language independent. Speech sounds can be described in a number of ways. Most commonly speech sounds are referred to by the mouth movements needed to produce them. Consonants and vowels are two gross categories that phoneticians define by the movements in a speech sound. More fine-grained descriptors are parameters such as place of articulation. Place of articulation, manner of articulation, and voicing are used to describe consonants and are the main divisions of the International Phonetic Alphabet consonant chart. Vowels are described by their height, backness, and rounding. Sign language are described using a similar but distinct set of parameters to describe signs: location, movement, hand shape, palm orientation, and non-manual features. In addition to articulatory descriptions, sounds used in oral languages can be described using their acoustics. Because the acoustics are a consequence of the articulation, both methods of description are sufficient to distinguish sounds with the choice between systems dependent on the phonetic feature being investigated.

Extracorporeal membrane oxygenation (ECMO) is a potential treatment, providing oxygenation through an apparatus that imitates the gas exchange process of the lungs. However, newborns cannot be placed on ECMO if they are under 4.5 pounds (2 kg), because they have extremely small vessels for cannulation, thus hindering adequate flow because of limitations from cannula size and subsequent higher resistance to blood flow (compare with vascular resistance). Furthermore, in infants aged less than 34 weeks of gestation, several physiologic systems are not well-developed, especially the cerebral vasculature and germinal matrix, resulting in high sensitivity to slight changes in pH, PaO and intracranial pressure. Subsequently, preterm infants are at unacceptably high risk for intraventricular hemorrhage (IVH) if administered ECMO at a gestational age of less than 32 weeks.

"Resistance" (R) proteins, encoded by R genes, are widely present in plants and detect pathogens. These proteins contain domains similar to the NOD Like Receptors and TLRs. Systemic acquired resistance (SAR) is a type of defensive response that renders the entire plant resistant to a broad spectrum of infectious agents. SAR involves the production of chemical messengers, such as salicylic acid or jasmonic acid. Some of these travel through the plant and signal other cells to produce defensive compounds to protect uninfected parts, e.g., leaves. Salicylic acid itself, although indispensable for expression of SAR, is not the translocated signal responsible for the systemic response. Recent evidence indicates a role for jasmonates in transmission of the signal to distal portions of the plant. RNA silencing mechanisms are important in the plant systemic response, as they can block virus replication. The "jasmonic acid response" is stimulated in leaves damaged by insects, and involves the production of methyl jasmonate.

The CSI is a graph-based technique that essentially employs an amino acid-specific digital filter to convert every assigned backbone chemical shift value into a simple three-state (-1, 0, +1) index. This approach generates a more easily understood and much more visually pleasing graph of protein chemical shift values. In particular, if the upfield Hα chemical shift (relative to an amino acid-specific random coil value) of a certain residue is > 0.1 ppm, then that amino acid residue is assigned a value of -1. Similarly, if the downfield Hα chemical shift of a certain amino acid residue is > 0.1 ppm then that residue is assigned a value of +1. If an amino acid residue's chemical shift is not shifted downfield or upfield by a sufficient amount (i.e. <0.1 ppm), it is given a value of 0. When this 3-state index is plotted as a bar graph over the full length of the protein sequence, simple inspection can allow one to identify beta strands (clusters of +1 values), alpha helices (clusters of -1 values), and random coil segments (clusters of 0 values). A list of the amino acid-specific random coil chemical shifts for CSI calculations is given in Table 1. An example of a CSI graph for a small protein is shown in Figure 1 with the arrows located above the black bars indicating locations of the beta strands and the rectangular box indicating the location of a helix.

Weyl applied his theory to Carl Friedrich Gauss's hypergeometric differential equation, thus obtaining a far-reaching generalisation of the transform formula of Gustav Ferdinand Mehler (1881) for the Legendre differential equation, rediscovered by the Russian physicist Vladimir Fock in 1943, and usually called the Mehler–Fock transform. The corresponding ordinary differential operator is the radial part of the Laplacian operator on 2-dimensional hyperbolic space. More generally, the Plancherel theorem for SL(2,R) of Harish Chandra and Gelfand–Naimark can be deduced from Weyl's theory for the hypergeometric equation, as can the theory of spherical functions for the isometry groups of higher dimensional hyperbolic spaces. Harish Chandra's later development of the Plancherel theorem for general real semisimple Lie groups was strongly influenced by the methods Weyl developed for eigenfunction expansions associated with singular ordinary differential equations. Equally importantly the theory also laid the mathematical foundations for the analysis of the Schrödinger equation and scattering matrix in quantum mechanics.

Levan has shown uses for burned tissue, anti-inflammation, and aquaculture. By combining levan into a thin film, it is able to activate an enzyme known as metalloproteinase which increases the recovery and healing process. In the case of inflammation, levan interacts with the aggregating cells and affects their adhesion to the blood vessel causing reduced accumulation. In aquaculture, results have shown that levan incorporated diets could possibly cause an increase in aggregation of viruses allowing for easier phagocytic removal. Levan produced by "Pantoea agglomerans" ZMR7 was reported to decrease the viability of rhabdomyosarcoma (RD) and breast cancer (MDA) cells compared with untreated cancer cells. In addition, it has high antiparasitic activity against the promastigote of "Leishmania tropica"

The "Picea/Abies" forests of the Alberta foothills are often characterized by deep accumulations of organic matter on the soil surface and cold soil temperatures, both of which make reforestation difficult and result in a general deterioration in site productivity; Endean and Johnstone (1974) describe experiments to test prescribed burning as a means of seedbed preparation and site amelioration on representative clear-felled "Picea/Abies" areas. Results showed that, in general, prescribed burning did not reduce organic layers satisfactorily, nor did it increase soil temperature, on the sites tested. Increases in seedling establishment, survival, and growth on the burned sites were probably the result of slight reductions in the depth of the organic layer, minor increases in soil temperature, and marked improvements in the efficiency of the planting crews. Results also suggested that the process of site deterioration has not been reversed by the burning treatments applied.

It started at 11:00 China Standard Time (UTC+8), and was scheduled to last until 17:30 later that day. The course ran north across the heart of the Beijing metropolitan area, passing such landmarks as the Temple of Heaven, the Great Hall of the People, Tiananmen Square and the Beijing National Stadium. After rolling over relatively flat terrain for north of the Beijing city center, the route entered a decisive circuit encompassing seven loops on a section up and down the Badaling Pass, including ramps as steep as a 10 percent gradient.

In the Unicode standard, iota subscript is represented by a non-spacing combining diacritic character U+0345 "Combining Greek Ypogegrammeni". There is also a spacing clone of this character (U+037A, ), as well as 36 precomposed characters, representing each of the usual combinations of iota subscript with lowercase , and , with and without any of the accent and breathing diacritics. In addition, for capitalized ("titlecase") use, Unicode provides a corresponding set of 27 precomposed code points with "prosgegrammeni" ( → ). Despite their name, which implies the use of an adscript glyph, these code points are defined as being equivalent to a combination of the base letter and the combining subscript character U+0345, just like their lowercase equivalents. They may be variously realized with either a subscript diacritic or a full-sized adscript iota glyph, depending on the font design. For use in all-capitals ("uppercase"), Unicode additionally stipulates a special case-mapping rule according to which lowercase letters should be mapped to combinations of the uppercase letter and uppercase iota ( → ). This rule not only replaces the representation of a monophthong with that of a diphthong, but it also destroys the reversibility of any capitalization process in digital environments, as the combination of uppercase letter and uppercase iota would normally be converted back to lowercase letter and lowercase iota. It is therefore strongly recommended, both for the integrity of text and for the practical compatibility with digital environments, that lowercase letter and iota subscript should be capitalized in all situations and contexts as uppercase letter and iota adscript. A future revision of the above-mentioned Unicode stipulation is linguistically stipulated and digitally inevitable, as its application is both destructive to the text and impractical in digital applications.

Control of Biak nearly became a critical turning point battle in the campaign for the Pacific. The Japanese had been seeking to engage the Americans in a decisive battle, the Kantai Kessen, that would enable them to win the war. Biak was not far from major Japanese fleet units and there were a number of land airfields nearby that could support the land-based aircraft the Japanese were hoping to concentrate to defeat the US fleet. The Imperial Navy's Chief of Staff, Admiral Ryūnosuke Kusaka, believed Biak represented the Allies' main effort, and a counterattack at Biak could provoke the US Navy into engaging in a major action. In response to the landing at Biak by US forces, the Japanese launched an operation to reinforce the area. Initially, for air support, the Japanese 23rd Air Flotilla initially only had 18 aircraft but was later reinforced with up to 166 aircraft, which were moved to Sorong, in Dutch New Guinea, arriving from Japan and the Marianas.

It spans of the donated by the Government of former Bombay State. While many states had offered land for a permanent place for the Academy, Bombay got the honour, donating the most land including a lake and neighboring hilly terrain. The site was also chosen for its proximity to the Arabian Sea and other military establishments, an operational air base nearby at Lohagaon as well as the salubrious climate. The existence of an old combined-forces training center and a disused "mock" landing ship, "HMS Angostura", on the north bank of the Khadakwasla lake which had been used to train troops for amphibious landings, lent additional leverage for the selection of the site.

Many hostnames used for the World Wide Web begin with "www" because of the long-standing practice of naming Internet hosts according to the services they provide. The hostname of a web server is often "www", in the same way that it may be "ftp" for an FTP server, and "news" or "nntp" for a Usenet news server. These hostnames appear as Domain Name System (DNS) or subdomain names, as in "www.example.com". The use of "www" is not required by any technical or policy standard and many web sites do not use it; the first web server was "nxoc01.cern.ch". According to Paolo Palazzi, who worked at CERN along with Tim Berners-Lee, the popular use of "www" as subdomain was accidental; the World Wide Web project page was intended to be published at www.cern.ch while info.cern.ch was intended to be the CERN home page; however the DNS records were never switched, and the practice of prepending "www" to an institution's website domain name was subsequently copied. Many established websites still use the prefix, or they employ other subdomain names such as "www2", "secure" or "en" for special purposes. Many such web servers are set up so that both the main domain name (e.g., example.com) and the "www" subdomain (e.g., www.example.com) refer to the same site; others require one form or the other, or they may map to different web sites. The use of a subdomain name is useful for load balancing incoming web traffic by creating a CNAME record that points to a cluster of web servers. Since, currently, only a subdomain can be used in a CNAME, the same result cannot be achieved by using the bare domain root.

The breakthrough for large molecule laser desorption ionization came in 1987 when Koichi Tanaka of Shimadzu Corp. and his co-workers used what they called the “ultra fine metal plus liquid matrix method” that combined 30 nm cobalt particles in glycerol with a 337 nm nitrogen laser for ionization. Using this laser and matrix combination, Tanaka was able to ionize biomolecules as large as the 34,472 Da protein carboxypeptidase-A. Tanaka received one-quarter of the 2002 Nobel Prize in Chemistry for demonstrating that, with the proper combination of laser wavelength and matrix, a protein can be ionized. Karas and Hillenkamp were subsequently able to ionize the 67 kDa protein albumin using a nicotinic acid matrix and a 266 nm laser. Further improvements were realized through the use of a 355 nm laser and the cinnamic acid derivatives ferulic acid, caffeic acid and sinapinic acid as the matrix. The availability of small and relatively inexpensive nitrogen lasers operating at 337 nm wavelength and the first commercial instruments introduced in the early 1990s brought MALDI to an increasing number of researchers. Today, mostly organic matrices are used for MALDI mass spectrometry.

The PPVT-IV provides an estimate of the client's verbal intelligence and has been administered to groups who had reading or speech problems, had intellectual disability, or were emotionally withdrawn. Studies of earlier versions of the test suggested that it tended to underestimate full-scale IQ scores for both intellectually disabled and gifted test-takers. Because the manner of the individual's response to stimulus vocabulary is to point in any fashion to one of four pictures that best fits the stimulus work, these tests also apply to rehabilitation of individuals who have multiple physical impairments, but whose hearing and vision are intact. The PPVT-IV can also be used for assessing the English vocabulary of non-English-speaking individuals and assessing adult verbal ability.

Kerberos was discovered by researchers of the Pluto Companion Search Team using the Hubble Space Telescope on 28 June 2011, using the Wide Field Camera 3, during an attempt to find any rings that Pluto might possess. The search for rings was motivated in part by a desire to avoid damage to "New Horizons" when it passed through the Pluto system in July 2015. Further observations were made on 3 and 18 July 2011 and Kerberos was verified as a new moon on 20 July 2011. It was later precovered or identified in earlier archival Hubble images from 15 February 2006 and 25 June 2010, though Kerberos was obscured by diffraction spikes in those images. Kerberos's brightness is only about 10% of that of Nix, and it was only found because the discovery team took eight-minute exposures; earlier observations had used shorter exposures. It was officially designated S/2011 (134340) 1, and was informally referred to as P4.

Trapped electrons only have a limited time frame when they are within the intermediate energy level stages. After a certain time range, or temperature fluctuations, trapped electrons will return to their energy states and recombine with holes. The recombination of electrons with their holes is only negligible if the average life is ten times higher than the age of the sample being dated. New heating events may erase previous ESR ages so in environments with multiple episodes of heating, such as in hydrothermal vents, maybe only newly formed minerals can be dated with ESR dating but not older minerals. This explains why samples from the same hydrothermal chimney may give different ESR ages. In environments with multiple phases of mineral formation, generally, ESR dating gives the average age of the bulk mineral while radiometric dates are biased to the ages of younger phases because of the decay of parent nuclei.

In a memoir read in September 1822, Fresnel announced that he had verified Brewster's diagnosis more directly, by compressing a combination of glass prisms so severely that one could actually see a double image through it. In his experiment, Fresnel lined up seven 45°-90°-45° prisms, short side to short side, with their 90° angles pointing in alternating directions. Two half-prisms were added at the ends to make the whole assembly rectangular. The prisms were separated by thin films of turpentine ("térébenthine") to suppress internal reflections, allowing a clear line of sight along the row. When the four prisms with similar orientations were compressed in a vise across the line of sight, an object viewed through the assembly produced two images with perpendicular polarizations, with an apparent spacing of 1.5mm at one metre.

The 2017–18 Arkansas–Pine Bluff Golden Lions men's basketball team represented the University of Arkansas at Pine Bluff during the 2017–18 NCAA Division I men's basketball season. The Golden Lions, led by 10th-year head coach George Ivory, played their home games at the K. L. Johnson Complex as members of the Southwestern Athletic Conference. They finished the season 14–21, 12–6 in SWAC play to finish in a three-way tie for second place. Due to Grambling State's Academic Progress Rate violations and subsequent postseason ineligibility, the Golden Lions received the No. 1 seed in the SWAC tournament. They defeated Mississippi Valley State and Southern before losing to Texas Southern in the tournament championship.
