A self-learning fuzzy controller (2003)

A learning scheme for the fuzzy control systems is proposed. The scheme can find proper control actions in the rule-base of a fuzzy controller for a number of different dynamic systems, including the cart-pole system. The learning scheme, which involves the ideas of temporal difference and fuzzy control, can construct a fuzzy controller, which can serve the control purpose on its own after the learning process. A number of different plant dynamics have also been tested, and the results suggest that the method is universal enough to control processes other than the commonly seen inverted pendulum.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
THE ELECTRONIC FLIGHT BAG: A MULTI-FUNCTION TOOL FOR THE MODERN COCKPIT (2002)

This research is intended to inform the reader about Electronic Flight Bags (EFBs). After an explanation of an EFB, a description of its development history, and short discussions of EFBs and human factors engineering and EFB products currently available in the aviation industry, the article discusses current and future display technologies -- the heart of the Electronic Flight Bag. The article continues by discussing the many potential applications of EFBs for general aviation and military aviation, as well some specific military benefits of their use. After reviewing some of the advantages and disadvantages of modifying cockpits to incorporate these devices, the author makes an argument for a cohesive joint effort during the design and implementation phases of EFBs. Finally, conclusions and recommendations are offered. The two appendices are designed to give examples of the many phases of flight an EFB can enhance. The examples are laid out in the form of two simulated flights. The first flight represents a peacetime cargo mission of a C-5 mission from Davis-Monthan AFB in Tucson, Arizona, to Eglin AFB in Fort Walton Beach, Florida. The second mission depicts a notional combat search and rescue (CSAR) mission flown by two A-10s into Iraq. This section is written in the first person from the perspective of Sandy 2, the wingman of a flight of two A-10s.
Cell-cycle regulation in green algae dividing by multiple fission (2014)

Green algae dividing by multiple fission comprise unrelated genera but are connected by one common feature: under optimal growth conditions, they can divide into more than two daughter cells. The number of daughter cells, also known as the division number, is relatively stable for most species and usually ranges from 4 to 16. The number of daughter cells is dictated by growth rate and is modulated by light and temperature. Green algae dividing by multiple fission can thus be used to study coordination of growth and progression of the cell cycle. Algal cultures can be synchronized naturally by alternating light/dark periods so that growth occurs in the light and DNA replication(s) and nuclear and cellular division(s) occur in the dark; synchrony in such cultures is almost 100% and can be maintained indefinitely. Moreover, the pattern of cell-cycle progression can be easily altered by differing growth conditions, allowing for detailed studies of coordination between individual cell-cycle events. Since the 1950s, green algae dividing by multiple fission have been studied as a unique model for cell-cycle regulation. Future sequencing of algal genomes will provide additional, high precision tools for physiological, taxonomic, structural, and molecular studies in these organisms.
La duración y la ultraactividad de los convenios colectivos (2013)

El convenio colectivo, a diferencia de la norma legal, se desenvuelve como una regulacion temporal, pero la parte laboral aspira a que cada logro se mantenga en el tiempo en tanto no se «mejore». De ahi el interes de las reglas sobre duracion, ultraactividad y cuestiones conexas y derivadas, que este estudio expone con maxima claridad.
Calcium-channel blockers and risk of cancer (1997)

The small positive association between calcium-channel blockers and risk of cancer is unlikely to be causal since there is no increase in risk with increasing duration of calcium-channel blocker use.
Flavor Losses in Orange Juice during Ultrafiltration and Subsequent Evaporation (1996)

ABSTRACT Losses of volatile compounds in orange juice during ultrafiltration and subsequent evaporation were studied. Alcohols and esters predominated in the permeate, while terpenes (d‐limonene and valencene) and nonpolar aldehydes (octanal and decanal) were distributed in the retentate from the ultrafiltration (UF) system. Fractions of some flavor compounds were lost during ultrafiltration process. An aqueous phase essence was recovered from the permeate during evaporative concentration. No oil phase was observed. When whole juice was concentrated, both oil and aqueous phases were recovered. Essence recovery efficiency of individual compounds was 3 to 13% when concentrating permeate and <5% when concentrating whole juice.
From Point to Local Neighborhood: Polyp Detection in CT Colonography Using Geodesic Ring Neighborhoods (2010)

Existing polyp detection methods rely heavily on curvature-based characteristics to differentiate between lesions. These assume that the discrete triangulated surface mesh or volume closely approximates a smooth continuous surface. However, this is often not the case and because curvature is computed as a local feature and a second-order differential quantity, the presence of noise significantly affects its estimation. For this reason, a more global feature is required to provide an accurate description of the surface at hand. In this paper, a novel method incorporating a local neighborhood around the centroid of a surface patch is proposed. This is done using geodesic rings which accumulate curvature information in a neighborhood around this centroid. This geodesic-ring neighborhood approximates a single smooth, continuous surface upon which curvature and orientation estimation methods can be applied. A new global shape index, S is also introduced and computed. These curvature and orientation values will be used to classify the surface as either a bulbous polyp, ridge-like fold or semiplanar structure. Experimental results show that this method is promising (100% sensitivity, 100% specificity for lesions > 10 mm) for distinguishing between bulbous polyps, folds and planar-like structures in the colon.

Water Potential Response in Fractured Basalt from Infiltration Events (2002)

The detection of moisture movement in the vadose zone beneath hazardous waste disposal sites is important for monitoring and predicting contaminant transport in the subsurface. This study was conducted to determine if moisture movement could be detected from natural water infiltration in a dual porosity, fractured basalt at the Idaho National Engineering and Environmental Laboratory (INEEL). Episodic infiltration events were determined by examining long-term water potential over three and a half years. Water potential measurements were collected from 2 to over 30 m below land surface. Instruments were placed in both fractured and unfractured basalt media. Water potential measurements were within the tensiometric range, from approximately +100 to −250 cm of water. Typically, water potentials within the fractured basalt exhibited a near steady-state unit-gradient downward flux. However, episodic snowmelt infiltration events at land surface produced detectable changes in water potentials at depths to 15.5 m, in some cases within a few days of the infiltration events. Smaller infiltration events were difficult to distinguish due to fluctuations in water potential resulting from changes in barometric pressure. Water potential responses in boreholes varied both temporally and spatially during episodic infiltration events indicating preferential flow pathways through the fractured basalt. The results of this study indicate that water potential measurements can be used to detect and monitor deep infiltration events at waste disposal sites using tensiometers.
Measuring ligand-dependent and ligand-independent interactions between nuclear receptors and associated proteins using Bioluminescence Resonance Energy Transfer (BRET<sup>2</sup>) (2006)

Bioluminescent resonance energy transfer (BRET2) is a recently developed technology for the measurement of protein-protein interactions in a live, cell-based system. BRET2 is characterized by the efficient transfer of excited energy between a bioluminescent donor molecule (Renilla luciferase) and a fluorescent acceptor molecule (a mutant of Green Fluorescent Protein (GFP2). The BRET2 assay offers advantages over fluorescence resonance energy transfer (FRET) because it does not require an external light source thereby eliminating problems of photobleaching and autoflourescence. The absence of contamination by light results in low background that permits detection of very small changes in the BRET2 signal. BRET2 is dependent on the orientation and distance between two fusion proteins and therefore requires extensive preliminary standardization experiments to conclude a positive BRET2 signal independent of variations in protein titrations and arrangement in tertiary structures. Estrogen receptor (ER) signaling is modulated by steroid receptor coactivator 1 (SRC-1). To establish BRET2 in a ligand inducible system we used SRC-1 as the donor moiety and ER as the acceptor moiety. Expression and functionality of the fusion proteins were assessed by transient transfection in HEK-293 cells followed by Western blot analysis and measurement of ER-dependent reporter gene activity. These preliminary determinations are required prior to measuring nuclear receptor protein-protein interactions by BRET2. This article describes in detail the BRET2 methodology for measuring interaction between full-length ER and coregulator proteins in real-time, in an in vivo environment.
Scheduling parallel applications using malleable tasks on clusters (2005)

Scheduling is a central issue for implementing applications on parallel and distributed systems. This problem has been intensively studied for conventional parallel systems. Clusters of SMP (symmetric Multi-Processors) are a cost effective alternative to parallel supercomputers which are more and more popular. New characteristics are influencing the execution of parallel applications, like for instance the hierarchical structure and the heterogeneity of the processors. Communications between SMP usually need some important latencies that create large communication delays. Designing efficient software that take full advantage of such systems remains difficult. The model of malleable task (MT) was introduced some years ago and has been proved to be an efficient way for implementing parallel applications on conventional systems. Here, the target application is considered at a larger level of granularity than in other models (corresponding typically to numerical routines) where the tasks can themselves be executed in parallel. In this paper, we are interested in designing efficient lowcost scheduling algorithms for implementing parallel applications for clusters. We first discuss the problems that occur while scheduling an application on parallel systems and give a classification of applications leading to various scheduling problems. For each of these problems, we will use the same methodology for optimizing the resource utilization of parallel programs.
Increased rates of initiation of polymerization by 4‐4′‐dicyano‐4‐4′‐azopentanoic acid in the presence of ferric salts (1966)

Abstract The initiation of the polymerization of acrylamide by 4‐4′‐dicyano‐4‐4′‐azopentanoic acid in aqueous solution has been studied kinetically at 25°C. Ferric chloride and ferric sulfate were used to terminate polymerization so that rates of initiation could be calculated from the rates of production of ferrous iron. Velocity coefficients at 25°C. for the initiation reaction were found to be (25.7 ± 2.8) × 10 −7 sec. −1 for the ferric chloride terminated reaction and (73.6 ± 0.6) × 10 −7 sec. −1 for the ferric sulfate‐terminated polymerization. The value reported for the initiation reaction when acrylamide is polymerized in the absence of metal salts is 1.29 × 10 −7 sec. −1 . Velocity coefficients for the termination reaction have been calculated from the overall rates of polymerization obtained with ferric salts present. In the case of the ferric chloride‐terminated reaction, it has been shown that the rate of polymerization is reduced by increasing the total concentration of chloride ions. Termination velocity coefficients at 25°C. for the inner sphere complexes FeCl 2+ ·5H 2 O and FeSO 4 + ·4H 2 O have been calculated to be 18.9 × 10 4 and 7.98 × 10 4 l./mole‐sec., respectively. The dependence on the concentration of ferric chloride of the molecular weights of the polymers produced has also been considered.
Comments on ‘‘On equations for the speed of sound in seawater’’ [J. Acoust. Soc. Am. <b>93</b>, 255–275 (1993)] (1994)

The recent measurements of acoustic arrival patterns [Dushaw et al., J. Acoust. Soc. Am. 93, 255–275 (1993); Spiesberger and Metzger, J. Acoust. Soc. Am. 89, 1697–1700 (1991); 89, 2677–2688 (1991)] indicate that the sound-speed equation of Del Grosso [J. Acoust. Soc. Am. 56, 1084–1091 (1974)] may be more reliable than the equation of Chen and Millero [J. Acoust. Soc. Am. 62, 1129–1135 (1977)] at low temperatures (0° to 15 °C) and high pressures (300 to 1000 bar). In this paper the possible causes of the difference and the resultant effect on the equation of state of seawater are discussed. The error in the sound-speed equation of Chen and Millero originated from the unreliable sound speeds for pure water determined by Wilson [J. Acoust. Soc. Am. 31, 1067–1072 (1959)] at low temperatures and high pressures. This difference does not affect the equation of state of seawater within the standard error of the equation (5×10−6 cm3/g in the specific volume at high pressures, vP). A correction has been derived that is valid from 0° to 15 °C to 1000 bar that can be used to correct the sound-speed equation of Chen and Millero. This correction allows one to use their equation over a much wider range of temperature, pressure, and salinity than the Del Grosso equation.
Curriculum Transformation (2016)

There is a global educational transformation movement to foster gender and sexuality curricula to improve the academic and schooling experiences of girls and lesbian, gay, bisexual, transgender, and questioning (LGBTQ) students. This rights‐based movement seeks to transform school climates and academic content to eradicate discrimination, bullying, gender‐based violence, and sexism. To ensure equity for girls and LGBTQ youth, changes are needed in educational ideologies that frame all aspects of education, in curriculum processes that influence school climate, and in school documents that shape learning. Capitalist and patriarchal approaches to education inhibit advancement of gender and sexuality curricula although research and resources for use in educational settings are widely available from non‐governmental organizations, community organizations, and university researchers.
Human-robot interaction and future industrial robotics applications (2010)

Industrial robots, designed for performing operations quickly, repeatedly and accurately have a long heritage in the manufacturing industry, operating in relatively static environments and in large numbers. Trends in the oil and gas industry to improve safety and efficiency and reduce environmental impact suggest the use of industrial robotics. New developments in regions difficult or dangerous for humans to work in could be enabled with maintenance, inspection and repairs carried out by remotely-controlled industrial robots. This new application area highlights some difficulties with today's robots, as they do not adapt well to dynamic environments, do not offer rich human-robot interaction and are not simple for end-users to program. In addition, the oil and gas context presents a challenging work environment for robots as they are exposed to variable and often extreme weather and need to be safe for use alongside explosive hydrocarbons. As robots are introduced, issues of trust and accountability come to the fore as well as how they fit into organisational structures. If robots have too little autonomy, human operators will waste time attending to robots instead of attending to their work tasks. If robots are highly autonomous, situational awareness of plant activity is diminished. A balance needs to be struck to find a level of autonomy suitable for the task, the realistic capabilities of the automation, and the need to actively engage human operators in a constructive fashion. These issues also relate to what form the interface takes for remote or co-located robot control, as well as how information and activity is represented for remote operators. The contribution of this paper is a discussion of issues relating to human-robot interaction for future industrial robotics, in particular for the oil and gas industry
Peer-to-peer cooperative caching in a hybrid data delivery environment (2004)

In a conventional mobile environment, mobile clients retrieve data items from database servers via mobile support stations, by downloading the items over scalable broadcast channels (push-based), requesting them over shared point-to-point channels (pull-based), or making use of both types of channels to retrieve them (hybrid). Caching is a key technique for improving data retrieval performance of mobile clients, regardless of the data delivery mechanism. The emergence of robust peer-to-peer technologies now brings to reality what we call "cooperative caching" in which mobile clients can access data items from the cache in their neighboring peers, thereby adding a new dimension for data caching. This paper studies the system performance of a cooperative caching scheme, called COCA, in a hybrid data delivery environment, and proposes a cooperative cache replacement scheme, called CORE, for mobile systems. The performance of COCA and CORE schemes is evaluated through a number of simulated experiments. The experiment results show that COCA effectively improves the system performance in push-based and hybrid-data delivery environments, especially in a heavily-loaded environment. The results also indicate that CORE can further improve on the access latency and reduce the number of expensive server requests, which consume scarce pull-based bandwidth.
Synthesis of 5-(3-Hydroxypropyl)-7-methoxy-2-(3‘-methoxy-4‘-hydroxyphenyl)-3- benzo[<i>b</i>]furancarbaldehyde, a Novel Adenosine A<sub>1</sub>Receptor Ligand from the Root of<i>Salvia miltiorrhiza</i> (1996)

A novel adenosine A1 receptor ligand, 5-(3-hydroxypropyl)-7-methoxy-2-(3‘-methoxy-4‘-hydroxyphenyl)-3-benzo[b]furancarbaldehyde (1), is a constituent of the roots of Salvia miltiorrhiza. Through biomimetic considerations, methyl ferulate was used as starting material for an eight-step synthesis of 1.
Acid Soluble Calf Skin Collagen (1971)

The α1‐chain of acid soluble calf skin collagen was cleaved with cyanogen bromide, and the resulting peptides were separated by ion exchange and molecular sieve chromatography. Eight different peptides could be isolated as expected from the seven methionyl residues of the chain. Their size was determined by gel filtration, dodecyl sulfate disc electrophoresis, measurement of electron micrographs of renatured peptides, and amino acid analysis. Peptides, differing in length between 19 and 270 residues were found. The C‐terminal peptide α1‐CB6 occurred in two variants (CB6 a and CB6 b ), differing in size, chromatographic behaviour and amino acid composition. The results suggest that CB6 a contains about 15 amino acid residues more than CB6 b . The amino acid compositions of the peptides were in good agreement with the composition of the α1‐chain. All CNBr‐peptides, including the sum of CB6 a and CB6 b , were isolated in approximately equimolar amounts, thus excluding the possibility of repeating sequences within the chain. The order of the CNBr‐peptides was established by electron microscopy and by comparative amino acid analysis of overlapping collagenase derived peptides and uncleaved CNBr‐peptides. It was found to be the same as in α1 from rat skin collagen.
Estimating conditional distributions using a method based on S-distributions reference percentile curves for body mass index in Spanish children. (2003)

The suggested methodology provides appropriate reference quantiles for the BMI. Our results allow characterizing the change in distribution within the age range considered. Besides describing a raise in BMI with age, we observe an increase in dispersion around puberty. This must be considered when using BMI as a diagnostic variable.

Y-Ba-Cu-O/Dy-Ba-Cu-O superlattices: A first step towards the artificial construction of high-<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">T</mml:mi></mml:mrow><mml:mrow><mml:mi mathvariant="normal">c</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math>superconductors (1989)

We have for the first time epitaxially grown superlattices of Y-Ba-Cu-O/Dy-Ba-Cu-O by dc magnetron sputtering onto ${\mathrm{SrTiO}}_{3}$ and MgO substrates. The wavelengths range from 24 (twice the c axis) to 300 A\r{} and x-ray diffractograms show satellite peaks characteristic of multilayers for each wavelength. The 24-A\r{}-wavelength sample consists of, on the average, alternate planes of Y and Dy. The multilayers are superconducting with ${\mathrm{T}}_{\mathrm{c}0}$'s between 85 and 89 K, transition widths of 2 K, and resistivity ratios of about 3.
