Experimental Results on Multiple-Input Single-Output (MISO) Time Reversal for UWB Systems in an Office Environment (2006)

This paper experimentally investigates the scheme of time reversal (TR) combined with multiple-input single-output (MISO) antennas over ultra-wideband (UWB) channels. In particular, temporal and spatial focusing as well as array gain are studied based on a (4times1) MISO scheme in an office environment. The results confirm that the energy of UWB signals in an MISO scheme is more spatial-temporally focused than in a single-input single-output (SISO) scheme. As a result, a strong peak is observed in the equivalent channel impulse response. The magnitude of this peak grows linearly with the square root of the number of antenna elements at the transmitter. All the measurements and data processing are completed in the time domain

SYNTHESE ET PROPRIETES DE SURFACE DE NOUVELLES 1,5-BENZODIAZEPINE-2,4-DIONES DERIVEES DU D-GLUCOSE (2015)

We synthesized a new glucose derivatives of 1,5-benzodiazepine-2,4-dione in view to study the influence of the glucidic moiety on the amphiphilic behaviour. Reaction of 1,5- benzodiazepine-2,4-dione with 3-O-alkyl-5,6-anhydro-1,2-O-isopropylidene-a-D-glucofuran-ose gave the expected N,N-bis-glucofuranosylbenzodiazepine derivatives which was deprotected to obtain the corresponding glucopyranosyl compounds. These compounds have a water solubility more higher than the starting 1,5-benzodiazepine- 2,4-diones. Morever some glucidic derivatives with an appropriate alkyl chain at the C-3 carbon of the D-glucose gave surface tension g in water at (25°C).

Changes in the taste and textural attributes of apples in response to climate change (2013)

The effects of climate change on the taste and textural attributes of foods remain largely unknown, despite much public interest. On the basis of 30-40 years of records, we provide evidence that the taste and textural attributes of apples have changed as a result of recent global warming. Decreases in both acid concentration, fruit firmness and watercore development were observed regardless of the maturity index used for harvest date (e.g., calendar date, number of days after full bloom, peel colour and starch concentration), whereas in some cases the soluble-solids concentration increased; all such changes may have resulted from earlier blooming and higher temperatures during the maturation period. These results suggest that the qualities of apples in the market are undergoing long-term changes.
Voice-Quality Monitoring and Control for VoIP (2005)

Voice over IP offers important opportunities for the telecommunications market to deploy more advanced services, but it must overcome many obstacles. Users expect toll-quality voice, which calls for end-to-end quality of service (QoS) - a challenge for IP service providers. To make VoIP attractive to end users, the only feasible and directly implementable alternative is to deploy an efficient mechanism within the endpoints. To that end, the authors propose the scalable, modular, call quality monitoring and control framework for maintaining voice quality at acceptable levels over networks that don't offer QoS guarantees.
Local Plant and Insect Conservation Evaluated with Organizational Identity Theory (2023)

With a range of programs focused on local plant and insect conservation, the Cincinnati Zoo &amp; Botanical Garden works with partners and our communities to restore landscapes and thriving ecosystems for wildlife and people. We used organizational identity theory (OIT) to evaluate the current strategies and practices of five programs and determine opportunities for adaptation to better achieve our organizational conservation goals. Case studies ranged from habitat restoration of wetlands and gardens to community engagement to encourage individual gardeners and the reintroduction of endangered plants and insects. We present program characteristics and how collaborative partnerships facilitate opportunities for zoos to lead the conservation of local flora and fauna. The OIT framework reveals components critical to strategy implementation and best practices relevant to other zoos, aquariums, and botanical gardens when evaluating their collaborative conservation initiatives.
The New Soehendra Stent Retriever Makes Stent Exchange Much Easier (2003)

Biliary stent exchange is usually performed in two steps: 1) removal of the occluded stent using either a snare or a rat-tooth forceps, and 2) placement of a new biliary stent. However, in cases of complicated strictures, recannulation of the stricture may be difficult or even impossible. The Soehendra stent retriever was designed to avoid such problems and guarantee stent replacement. Those using this device for replacing on occluded stent may, however, encounter difficulties in inserting the guide wire into the stent and advancing the retriever over the guide wire to engage the distal end of the stent. This drawback has recently been eliminated by modifying the tip of the retriever (Figures [1] and [2].)
Label-free biological sensors based on ring resonators (2008)

This paper reports the progress (design, fabrication and measurement) in label-free biological sensors based on ring resonator technology originally developed for telecommunication. These sensors are made in silicon-on-insulator (SOI), a high index contrast material platform that provides enhanced sensitivity and allows compact waveguide geometries by employing very small bend radii. A double spiral shape allows designing millimetre-long resonator in a compact size (100−150 μm) compatible with spotting technology used for large biochip assays. The detection limit estimated from the resonance shift measurement is ∼5 fg of streptavidin adsorbed on the sensor surface functionalised with biotin.
Profiling Ubiquitin and Ubiquitin-like Dependent Post-translational Modifications and Identification of Significant Alterations (2019)

Ubiquitin (ub) and ubiquitin-like (ubl) dependent post-translational modifications of proteins play fundamental biological regulatory roles within the cell by controlling protein stability, activity, interactions, and intracellular localization. They enable the cell to respond to signals and to adapt to changes in its environment. Alterations within these mechanisms can lead to severe pathological situations such as neurodegenerative diseases and cancers. The aim of the technique described here is to establish ub/ubls dependent PTMs profiles, rapidly and accurately, from cultured cell lines. The comparison of different profiles obtained from different conditions allows the identification of specific alterations, such as those induced by a treatment for example. Lentiviral mediated cell transduction is performed to create stable cell lines expressing a two-tags (6His and Flag) version of the modifier (ubiquitin or a ubl such as SUMO1 or Nedd8). These tags permit the purification of ubiquitin and therefore of ubiquitinated proteins from the cells. This is done through a two-step purification process: The first one is performed in denaturing conditions using the 6His tag, and the second one in native conditions using the Flag tag. This leads to a highly specific and pure isolation of modified proteins which are subsequently identified and semi-quantified by liquid chromatography followed by tandem mass spectrometry (LC-MS/MS) technology. Easy informatics analysis of MS data using Excel software enables the establishment of PTM profiles by eliminating background signals. These profiles are compared between each condition in order to identify specific alterations which will then be studied more specifically, starting with their validation by standard biochemistry techniques.
An algorithm for the identification of proteins using peptides with ragged N‐ or C‐termini generated by sequential endo‐ and exopeptidase digestions (1998)

We have developed an algorithm (MassDynSearch) for identifying proteins using a combination of peptide masses with small associated sequences (tags). Unlike the approach developed by Matthias Mann, 'Tag searching', in which the sequence tags are generated by gas phase fragmentation of peptides in a mass spectrometer, 'Rag Tag' searching uses peptide tags which are generated enzymatically or chemically. The protein is digested either chemically or with an endopeptidase and the resultant mixture is then subjected to partial exopeptidase degradation. The mixture is analyzed by matrix assisted laser desorption and ionization time of flight mass spectrometry and a list of intact peptide masses is generated, each associated with a set of degradation product masses which serve as unique tags. These 'tagged masses' are used as the input to an algorithm we have written, MassDynSearch, which searches protein and DNA databases for proteins which contain similar tagged motifs. The method is simple, rapid and can be fully automated. The main advantage of this approach is that the specificity of the initial digestion is unimportant since multiple peptides with tags are used to search the database. This is especially useful for proteins like membrane, cytoskeletal, and other proteins where specific endopeptidases are less efficient and lower specificity proteases such as chymotrypsin, pepsin, and elastase must be used.
High Performance CMOS Variability in the 65nm Regime and Beyond (2007)

This paper has described the performance of CMOS and categorises the variability. The inability to scale the tolerance of multiple electrical parameters along with their nominal value has contributed to a virtual crisis in the ability to improve performance and power consumption in new processes. The continued infusion of new materials and structures provide an illusion of conventional scaling, but assert additional idiosyncrasies as well. New device structures and materials may allow CMOS to scale further, but variability isn't likely to decrease, since smaller devices contain fewer atoms and consequently exhibit less self-averaging. The situation may be improved by removing most of the doping.
SAR, ISAR and hybrid SAR/ISAR-a unified treatment of radar imaging (2002)

The modeling of aperture synthesis as a process of Fourier transformation and inversion provides a unified description of synthetic aperture radar (SAR), inverse SAR (ISAR) and hybrid SAR/ISAR techniques. The degradation of the resulting imagery arising from errors in the estimation of target and platform motions and operation in the near field is analyzed clearly and concisely, the results being expressed in a compact matrix form. The verification of this analysis by computer simulation and possible future applications of the formalism developed are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Application of MPP to particle tracking (1993)

The SSC requires massive simulation to support the design, commissioning, and operation of the accelerator complex. To this end, the laboratory has made a significant commitment to MPP for this application. A 64 node IPSC/860 was acquired in January of 1991 and has been used extensively in tracking studies of various accelerators of the SSC injector chain. This talk will detail the accomplishments to date and lessons learned.The most basic observation one can make about tracking on a parallel computer is that for a thin element kick code in the absence of space charge, the problem has a natural granularity that makes it ‘‘embarrassingly parallel.’’ One simply distributes the particles over available nodes and tracks. No intermode communication is required except for a small amount of diagnostic information that is generated as the run progresses. Hence, the parallel efficiency approaches 100 percent and the problem is scalable to a large number of processors.This seemingly trivial observation leads immediately to two important conclusions regarding the hardware configuration used to do the tracking. The number of computational nodes should not exceed the number of particles tracked and the overall performance of the calculation will be dominated by single node performance.The situation becomes less clear as more intermode communication is added. The performance of the MPP system on runs where beam emittance is monitored or beam instrumentation is simulated are progressively influenced by message passing overhead. In general, one must be aware that it is sometimes better to abandon the natural granularity and compromise network performance in the interests of optimizing individual node performance.The addition of space charge forces to the tracking code requires a PIC calculation to be done concurrently with the thin element tracking. A procedure for dynamically sorting particles on to nodes that optimizes machine performance will be described.The application of a MPP to serve as the engine of real time simulator will be discussed. Such factors as predictability of network collisions and the interrupt response time of the individual node required to write out data becomes important.An interactive visualization system designed to display the results from the space charge calculation will be described. It has great flexibility in choice of viewpoint, reference frame and data density.
기후변화가 농업용 저수지의 저수량에 미치는 영향 및 대응 방안 제시 (2009)

본 연구는 기후변화에 따른 농업용저수지유역의 저수량과 유입량의 잠재적인 영향을 평가하고자 하며, 이 변화의 대응방안으로써 미래 방류량 조정에 따른 저수위 관리 가능여부를 판단해보고자 한다. 미래 기후변화 영향 평가를 위해 장기수문유출모형인 SLURP 모형이 선택되었으며, 모형의 물리적 매개변수들과 농업용저수지의 방류량을 조정하여 저수지의 유역유출량을 9개년 기간 동안 검·보정하였다. 또한 미래 기후변화자료를 구축하기 위하여 4개의 GCMs의 A1B 시나리오를 선택하여 편이보정과 CF 다운스케일기법을 이용하였다. 미래의 기후변화에 따라 저수지유역의 저수량을 평가한 결과, 가을에 저수량이 감소하기 시작해서 겨울이 끝나는 시점에도 저수량을 회복하지 못하는 것으로 분석되었다. 이는 다음해의 저수량에 큰 영향을 미치므로 이에 대한 대응방안이 필요하며, 그 방안으로 8월과 9월의 방류량을 감소시킴으로써 가을과 겨울의 저수량이 100%회복되는 것을 확인할 수 있었다.
A Sensitive Electronic Photoreceptor (1985)

The photoreceptors in biological systems give meaningful outputs over about six orders of magnitude of illumination intensity. If we are to build an electronic vision system that is truly useful, it must have a similar dynamic range. The elements of an electronic receptor with many orders of magnitude dynamic range are described below. Experimental&#13;\ndevices were fabricated in p-well cMOS bulk technology through the MOSIS foundry; npn phototransistors with collector connected to substrate are a byproduct of this process. The n-type bulk forms the collector, the p-well is the base, and the n+ diffusion the emitter. In a&#13;\ntypical process, a large transistor of this sort has a current gain β of more than a thousand. Smaller transistors have lower current gains, but are still respectable. The key to very sensitive receptors is to use the current&#13;\ngain of this very clean bipolar transistor before subjecting the signal to any noise from subsequent amplification stages.
Time to Start Calling Things by Their Own Names? The Case for Antiseizure Medicines (2020)

Medicines currently used in the management of epilepsy have been developed to suppress seizures, and they have no known impact on the underlying disease. Using the term "antiepileptic" to describe these compounds is misleading because it suggests an action on the epilepsy itself. Pharmacological agents that have a merely symptomatic effect should be referred to as antiseizure medicines. Using appropriate terminology is especially important at a time innovative treatments targeting the development of epilepsy and its comorbidities are being actively pursued.
Taming Silylium Ions for Synthesis: N-Heterocycle Synthesis via Stereoselective C–C Bond Formation (2017)

Silylium ions (formally [R3Si]+) have long been the subject of investigations and significant debate in both theoretical and experimental chemistry, but few catalytic, synthetic applications have been reported due to the exceptionally high reactivity and Lewis acidity of these elusive species. Results to be discussed include the application of easily accessible silylium ion catalysts to the stereoselective synthesis of various N-heterocyclic pyrrolidine and piperidine scaffolds. The tested substrates are derived from the chiral pool and can be obtained in three high-yielding steps from amino alcohols; subsequent stereoselective silylium ion catalyzed Prins cyclization and trapping with R3Si–Nu nucleophiles (e.g., Nu = H, allyl, azide, and enol ethers) results in novel nitrogen-containing polycyclic scaffolds with potential medicinal chemistry applications.
An intercellular pathway for glucose transport into mouse oocytes (2012)

Glucose is an essential nutrient for mammalian cells. Emerging evidence suggests that glucose within the oocyte regulates meiotic maturation. However, it remains controversial as to whether, and if so how, glucose enters oocytes within cumulus-oocyte complexes (COCs). We used a fluorescent glucose derivative (6-NBDG) to trace glucose transport within live mouse COCs and employed inhibitors of glucose transporters (GLUTs) and gap junction proteins to examine their distinct roles in glucose uptake by cumulus cells and the oocyte. We showed that fluorescent glucose enters both cumulus-enclosed and denuded oocytes. Treating COCs with GLUT inhibitors leads to simultaneous decreases in glucose uptake in cumulus cells and the surrounded oocyte but no effect on denuded oocytes. Pharmacological blockade of of gap junctions between the oocyte and cumulus cells significantly inhibited fluorescent glucose transport to oocytes. Moreover, we find that both in vivo hyperglycemic environment and in vitro high-glucose culture increase free glucose levels in oocytes via gap junctional channels. These findings reveal an intercellular pathway for glucose transport into oocytes: glucose is taken up by cumulus cells via the GLUT system and then transferred into the oocyte through gap junctions. This intercellular pathway may partly mediate the effects of high-glucose condition on oocyte quality.

Molecular Characterization of Podoviral Bacteriophages Virulent for Clostridium perfringens and Their Comparison with Members of the Picovirinae (2012)

Clostridium perfringens is a Gram-positive, spore-forming anaerobic bacterium responsible for human food-borne disease as well as non-food-borne human, animal and poultry diseases. Because bacteriophages or their gene products could be applied to control bacterial diseases in a species-specific manner, they are potential important alternatives to antibiotics. Consequently, poultry intestinal material, soil, sewage and poultry processing drainage water were screened for virulent bacteriophages that lysed C. perfringens. Two bacteriophages, designated ΦCPV4 and ΦZP2, were isolated in the Moscow Region of the Russian Federation while another closely related virus, named ΦCP7R, was isolated in the southeastern USA. The viruses were identified as members of the order Caudovirales in the family Podoviridae with short, non-contractile tails of the C1 morphotype. The genomes of the three bacteriophages were 17.972, 18.078 and 18.397 kbp respectively; encoding twenty-six to twenty-eight ORF's with inverted terminal repeats and an average GC content of 34.6%. Structural proteins identified by mass spectrometry in the purified ΦCP7R virion included a pre-neck/appendage with putative lyase activity, major head, tail, connector/upper collar, lower collar and a structural protein with putative lysozyme-peptidase activity. All three podoviral bacteriophage genomes encoded a predicted N-acetylmuramoyl-L-alanine amidase and a putative stage V sporulation protein. Each putative amidase contained a predicted bacterial SH3 domain at the C-terminal end of the protein, presumably involved with binding the C. perfringens cell wall. The predicted DNA polymerase type B protein sequences were closely related to other members of the Podoviridae including Bacillus phage Φ29. Whole-genome comparisons supported this relationship, but also indicated that the Russian and USA viruses may be unique members of the sub-family Picovirinae.

Effects of a strong π-accepting ancillary ligand on the water oxidation activity of weakly coupled binuclear ruthenium catalysts (2019)

Significant differences were found in the proton-coupled redox chemistry and catalytic behavior of the binuclear [{Ru(H2O)(bpz)}2(tpy2ph)](PF6)4 complex [bpz = 2,2'-bipyrazine; tpy2ph = 1,3-bis(4'-2,2':6',2''-terpyridin-4-yl)benzene] as compared with the structurally analogous derivative with 2,2'-bipyridine (bpy) instead of bpz. The differences were assigned to the stronger π-accepting character of bpz relative to bpy as the ancillary ligand. The expectation of a positive shift for the Ru-centered redox potentials was confirmed for the lower oxidation state species, but that trend was reversed in the formation of the high-valence catalytic active species as shown by a negative shift of 0.14 V for the potential of the [RuIV/V[double bond, length as m-dash]O] process. Moreover, DFT calculations indicated a significant decrease of about 15% on the spin density and oxyl character of the [RuV[double bond, length as m-dash]O]3+ fragment. The significantly lower kcat(O2) for the bpz system was attributed to these combined electronic effects.
