Effects of Plyometric Training on Power and Power-Endurance in High School Basketball Players (2003)

PURPOSE: This study examined the effects of plyometric training on power and power-endurance performance in high school basketball players. METHODS: Twenty male basketball players aged 16-19 participated in this study. Several types of vertical jump tests were performed on a force platform to measure force, velocity, and power production during vertical jumping. The Wingate anaerobic test was performed on a bicycle ergometer, and the blood lactate concentrations were assessed before and at 5 and 30 minutes after the test. Subjects completed these test and were randomly divided into two groups, control and treatment .All subjects completed the usual preseason basketball on-court training and a weight-training program. Furthermore, the treatment group completed 8 weeks of plyometric training. Both groups were retested at the completion of the training period. RESULTS: The peak and mean power of the Wingate anaerobic test were significantly improved in the treatment group; however, the percent fatigue was unchanged. There were no significant differences in blood lactate concentrations over time in the pre-training between the two groups. In particular, the blood lactate concentration at pre-test in post-training in the treatment group was significantly lower than the control group (treatment vs. control, 0.95±0.18 vs. 1.50±0.35 mM•L-1, p ＜ .05). The treatment group produced significant increases in 1RM half-squat strength, squat jumps (SJ) and counter movement jump (CMJ) performance over the training period. However, there were significant differences only on the 1RM half-squat strength in the control group after training. There were no significant differences in the numbers of jumps (treatment: 42.0±15.8 to 45.6±15.7 times, p ＞ .05; control: 46.9±14.8 to 45.0±10.8 times, p ＞ .05), and total power output (treatment: 991.1±484.7 to 1l91.4±622.5 W．kg-1, p＞ .05; control: 1l93.5±412.0 to 1214.5±408.4 W•kg-1, p＞.05) during CJ (continuous jumps) after training. CONCLUSION: These results lend support to the effectiveness of an 8-weeks combination of weight and plyometric training for improving vertical jump and power performance in high school basketball players, but not power-endurance performance.
Crystal structures and physical properties of flurbiprofen salts (2005)

parameters a 12.5, b 6.2, c 18.4 , and V 1400 3 . Similar to the LnNiSb 2 compounds, these compounds are layered but consist of rare-earth atoms located above and below planes of nearly square, buckled Sb nets, however with layers of highly distorted edge-and face-sharing NiSb 6 octahedra. The structures of the LnNi x Sb 2 (Ln = Y, Gd -Er; x 0.6) and LnNiSb 3 (Ln = Pr, Nd, Sm) compounds are similar to the structure of the simple binary phases LnSb 2 (Ln = La-Nd, Sm, Gd-Er). In an effort to correlate and elucidate the origin of the physical behavior observed, the structural units found within these three families will be compared.
High-efficiency power supplies for home computers and servers (2006)

Most likely, the computer you’re using wastes 30-40% of the electrical power it consumes because it is using an inefficient power supply. It’s difficult to believe that something as basic as a power supply could be responsible for that amount of waste, but it’s true. The problem with power supplies is that they generate heat, which saps away energy meant to power the computer. That happens when the power supply converts AC current into the DC current needed by computers.
Conservation of molecular and cellular phenotypes of invariant NKT cells between humans and non-human primates (2019)

Invariant NKT (iNKT) cells in both humans and non-human primates are activated by the glycolipid antigen, α-galactosylceramide (α-GalCer). However, the extent to which the molecular mechanisms of antigen recognition and in vivo phenotypes of iNKT cells are conserved among primate species has not been determined. Using an evolutionary genetic approach, we found a lack of diversifying selection in CD1 genes over 45 million years of evolution, which stands in stark contrast to the history of the MHC system for presenting peptide antigens to T cells. The invariant T cell receptor (TCR)-α chain was strictly conserved across all seven primate clades. Invariant NKT cells from rhesus macaques (Macaca mulatta) bind human CD1D-α-GalCer tetramer and are activated by α-GalCer-loaded human CD1D transfectants. The dominant TCR-β chain cloned from a rhesus-derived iNKT cell line is nearly identical to that found in the human iNKT TCR, and transduction of the rhesus iNKT TCR into human Jurkat cells show that it is sufficient for binding human CD1D-α-GalCer tetramer. Finally, we used a 20-color flow cytometry panel to probe tissue phenotypes of iNKT cells in a cohort of rhesus macaques. We discovered several tissue-resident iNKT populations that have not been previously described in non-human primates but are known in humans, such as TCR-γδ iNKTs. These data reveal a diversity of iNKT cell phenotypes despite convergent evolution of the genes required for lipid antigen presentation and recognition in humans and non-human primates.
A new VR bike system for balance rehabilitation training (2002)

Describes a bike system for the postural balance rehabilitation training. A virtual environment and three dimensional graphic models are designed with CAD tools such as 3D Studio Max/sup TM/ and World Up/sup TM/. For the real time bike simulation, the optimized WTK graphic library is embedded with the dynamic geometry generation method, multi-thread method, and portal generation method. In an experiment, 20 normal adults were tested to investigate the influencing factors of balancing posture. We evaluated the system by measuring the parameters such as path deviation, driving velocity, COP, and average weight shift. Also, we investigated the usefulness of visual feedback information by weight shift. The results showed that visual stimulus of continuous visual feedback by weight shift way more effective than that of non-visual feedback in the postural balance control. It is concluded that this system might be applied in clinical use as a postural balance training system.

Platelet Factor Four and Protamine Sulfate Neutralization of Heparin Fractionated According to Anionic Charge Density (1982)

The role of heparin structure in neutralization by the neutralizing substances (NS) platelet factor 4 (PF4) and protamine sulfate (PS) was investigated using a thrombin clotting assay and a series of more homogeneous heparin fractions varying systematically in charge density (Z). For a given heparin, plotting inverse clotting times measured without NS, and in the presence of PF4 or PS, vs heparin concentration yielded approximately parallel straight lines displaced horizontally according to the amount of NS. Potencies of heparin fractions in the absence of NS, or in the presence of PF4 of PS, depended almost identically upon Z2. Small but significant quantitative differences in potency among equivalent fractions from different heparins showed both PF4 and PS had a slight preference for the least active subfraction of decolorized heparins, but for the most active subfraction of undecolorized heparins. Neutralization of heparin by PF4 and PS probably proceeds by similar mechanisms, but the details of structure outside the antithrombin III-binding oligosaccharide of heparin may enter in differently.
High-throughput surface plasmon resonance imaging-based biomolecular kinetic screening analysis (2010)

In this paper we show a high-throughput method to screen the kinetics and affinity constants of many biomolecular interactions simultaneously. During the preparation of the sensor chip, ligands were serially diluted and spotted in a 6 × 4 microarray on the sensor surface. A multi-analyte sample was injected and the real-time surface plasmon resonance (SPR) responses of all the 24 microarray spots were obtained using a commercial SPR imaging instrument. The multi responses of the association and dissociation processes obtained from a single analyte injection are sufficient to calculate the rates and affinity constants of the interactions between three interactant antigen-antibody pairs using a simple monophasic kinetic model. The method drastically reduces the measurement time and cost in the benefit of increased throughput.
An exceptional family: Ophiocordyceps‐allied fungus dominates the microbiome of soft scale insects (Hemiptera: Sternorrhyncha: Coccidae) (2017)

Hemipteran insects of the suborder Sternorrhyncha are plant sap feeders, where each family is obligately associated with a specific bacterial endosymbiont that produces essential nutrients lacking in the sap. Coccidae (soft scale insects) is the only major sternorrhynchan family in which obligate symbiont(s) have not been identified. We studied the microbiota in seven species from this family from Israel, Spain and Cyprus, by high-throughput sequencing of ribosomal genes, and found that no specific bacterium was prevalent and abundant in all the tested species. In contrast, an Ophiocordyceps-allied fungus sp.-a lineage widely known as entomopathogenic-was highly prevalent. All individuals of all the tested species carried this fungus. Phylogenetic analyses showed that the Ophiocordyceps-allied fungus from the coccids is closely related to fungi described from other hemipterans, and they appear to be monophyletic, although the phylogenies of the Ophiocordyceps-allied fungi and their hosts do not appear to be congruent. Microscopic observations show that the fungal cells are lemon-shaped, are distributed throughout the host's body and are present in the eggs, suggesting vertical transmission. Taken together, the results suggest that the Ophiocordyceps-allied fungus may be a primary symbiont of Coccidae-a major evolutionary shift from bacteria to fungi in the Sternorrhyncha, and an important example of fungal evolutionary lifestyle switch.

Metal‐Free Deoxygenation of Chiral Nitroalkanes: An Easy Entry to α‐Substituted Enantiomerically Enriched Nitriles (2021)

A metal-free, mild and chemodivergent transformation involving nitroalkanes has been developed. Under optimized reaction conditions, in the presence of trichlorosilane and a tertiary amine, aliphatic nitroalkanes were selectively converted into amines or nitriles. Furthermore, when chiral β-substituted nitro compounds were reacted, the stereochemical integrity of the stereocenter was maintained and α-functionalized nitriles were obtained with no loss of enantiomeric excess. The methodology was successfully applied to the synthesis of chiral β-cyano esters, α-aryl alkylnitriles, and TBS-protected cyanohydrins, including direct precursors of four active pharmaceutical ingredients (ibuprofen, tembamide, aegeline and denopamine).
Designing Multi-functional Metamaterials (2022)

The ability to design passive structures that perform different operations on different electromagnetic fields is key to many technologies, from beam-steering to optical computing. While many techniques have been developed to optimise structure to achieve specific functionality through inverse design, designing multi-function materials remains challenging. We present a semi-analytic method, based on the discrete dipole approximation, to design multi-functional metamaterials. To demonstrate the generality of our method, we design a device that operates at optical wavelengths and beams light into different directions depending on the source polarisation and a device that works at microwave wavelengths and sorts plane waves by their angle of incidence.

Mutational and Biochemical Analysis of Isoprenylcysteine Carboxyl Methyltransferase (2016)

Ninety percent of pancreatic cancers are attributed to mutations in the Ras protein, making it paramount to concentrate on Ras activity. This study focuses on Ras activity by targeting a post-translational modifying enzyme of Ras called Isoprenylcysteine carboxyl methyltransferase (Icmt). Elucidation of the binding site of Icmt will allow the development of therapeutics that effectively inhibit Icmt causing the mislocalization of Ras, and in turn, aid in the treatment of Ras driven cancers. Currently, the hydrophobic substrate binding site of Icmt is unknown. In order to characterize the substrate binding site of Icmt, site-directed mutagenesis was used to design mutations in the yeast homolog of Icmt, Ste14p, and these mutants were tested on substrate specificity. Residues L33, L34, L40, L176, L190, and L195 were mutated to alanine and residue F80 was mutated to tyrosine. When tested with a methyltransferase assay, all of the mutants lost activity as compared to wild type (WT). Noticeably, L190A had only 44% WT activity. This suggests that L190A is important for either substrate binding or the overall structural integrity of Ste14p. The results from trypsin digestion show that all mutants have cleavage patterns similar to WT. This indicates that the structural integrity of Ste14p remains intact regardless of these mutations. Substrate specificity and photolabeling experiments should be conducted in the future to elucidate if these residues are vital for the substrate binding site of Icmt. These results could be utilized to design more potent and effective drug therapies to minimize Ras signaling in cancer cells.
Spatio-temporal forecasting of weather-driven damage in a distribution system (2015)

A major ongoing effort by utilities is to improve their emergency preparedness process for weather events, in order to: 1) reduce outage time 2) reduce repair and restoration costs and 3) improve customer satisfaction. This paper proposes a method for forecasting the number of damages of different types that will result from a weather event, up to 3 days before the event actually occurs. The proposed method overcomes practical issues with sparsity of historical damage and weather records by 1) using a spatial clustering-based scheme to work even in cases where there are very few historical incidents of damage, 2) combining data from multiple weather observation networks, 3) using weather hindcast data and 4) accounting for variability in damage susceptibility across different substation regions. The performance of the method is evaluated on real utility data.
Suppressing the Cliff Effect in Video Reproduction Quality (2012)

The cliff effect is a phenomenon evidenced when the quality of received data drops abruptly when the channel quality falls below a critical point and does not improve once the channel quality surpasses this point. In modern networks (content delivery networks (CDNs), mobile, wireless), when content is transmitted over diverse channels to heterogeneous users, the cliff effect becomes a major impediment. In simultaneous video delivery to multiple users, the users with channel quality below the critical point will receive unwatchable streams, whereas those whose channel quality is well above it will not see any improvement. We propose a multiple description based joint source-channel coding approach to suppress the cliff effect in video delivery, which can be optimized according to a statistical description of the channels, and specific requirements of the application. After introducing the analytical model of the proposed approach, we describe two possible strategies to modify state-of-the-art video codecs. This involves design of a new data processing block based on linear complexity encoding by sparse codes, which is our ongoing work. © 2012 Alcatel-Lucent.
Synthesis, crystal structures and reactivity of rhodium(III) complexes containing β-ketophosphine and phosphino enolate ligands (1995)

The reaction of 3 equivalents of the ketophosphine Ph2PCH2C(O)Ph (L) with RhCl3·3H2O in ethanol yielded [[graphic omitted])Ph}{Ph2PCH2C(O)Ph}] in the form of the mer,trans-(1) and mer,cis-(2) isomers. Complex 2 exhibits fluxional behaviour on the 1H NMR time-scale as a result of dynamic exchange between the pendant and the co-ordinated keto functions, the activation energy for this process being 75 ± 2 kJ mol–1. Treatment of 2 with TIPF6 in CH2Cl2 afforded the cationic complex trans,cis,cis-[[graphic omitted])Ph}2]PF63, which reacts with excess L to give mer,cis-[[graphic omitted])Ph}{Ph2PCH2C(O)Ph}]PF65. Complex 5 has an unprecedented ligand set: two ligands L, Bound in two different co-ordination modes (terminal through P and chelating), and the corresponding phosphino enolate as the other chelate. In solution, fluxional behaviour is observed by 31P NMR spectroscopy with an activation energy of 56 ± 1 kJ mol–1. The reaction of 3 with NaH afforded [{[graphic omitted])Ph]2}2]6. The chloride bridges are readily cleaved by PMePh2, affording [[graphic omitted])Ph}2(PMePh2)]7. Treatment of [RhCl(PPh3)3] with 3 equivalents of L in toluene afforded the RhIII complex mer,cis-[[graphic omitted])Ph2{Ph2PCH2C(O)Ph}]8. Complex 2 and L reacted with NaOMe to afford the tris(enolato) RhIII complex fac-[[graphic omitted])Ph}3]9, which could be also obtained from [RhCl(PPh3)3].

Multi-Source Remote Sensing Image Fusion for Ship Target Detection and Recognition (2021)

The active recognition of interesting targets has been a vital issue for remote sensing. In this paper, a novel multi-source fusion method for ship target detection and recognition is proposed. By introducing synthetic aperture radar (SAR) sensor images, the proposed method solves the problem of precision degradation in optical remote sensing image target detection and recognition caused by the limit of illumination and weather conditions. The proposed method obtains port slice images containing ship targets by fusing optical data with SAR data. On this basis, spectral residual saliency and region growth method are used to detect ship targets in optical image, while SAR data are introduced to improve the accuracy of ship detection based on joint shape analysis and multi-feature classification. Finally, feature point matching, contour extraction and brightness saliency are used to detect the ship parts, and the ship target types are identified according to the voting results of part information. The proposed ship detection method obtained 91.43% recognition accuracy. The results showed that this paper provides an effective and efficient ship target detection and recognition method based on multi-source remote sensing images fusion.
Histoire des formes orales à libération prolongée et de la contribution de la pharmacie galénique dans ce domaine (2005)

The second part of the XXth century have seen the creation of new systems of administration for drugs, including delayed formulation systems or prolonged-release formulations (PRF). It is first within the industry, and mainly in the USA, that such new formulations were developed, with the purpose to increase the duration of action for pharmaceutical active principles. Several approaches were proposed and developed, jointly with more and more sophisticated evaluation techniques. In France, PRF market increased progressively during the 1980's; it then decreased because of more severe restrictions by health authorities for new drug approvals. In French specialty reference book (Vidal) included 518 PRF in the year 2000, from which 121 were tablets and 118 were hard gelatine capsules.
Control of distributed UPS systems (2002)

This paper is concerned with the control aspects of distributed uninterruptible power supply (UPS) systems. These are systems in which the UPS units and the critical loads are located flexibly in an interconnected network in the manner of a typical power system. Decentralized control without data communication is an essential control requirement for such systems. The main aim of this paper is the identification of the major control aspects of distributed UPS systems, and the development of solutions to these control issues.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Semantic knowledge driven utility calculation towards efficient multi-robot task allocation (2018)

With the advent of Industry 4.0 era, employing a team of robots within a factory floor or a warehouse is pretty prevalent today as robots can perform a known task with higher accuracy and efficiency if its capability permits. Efficiency and throughput of such a setup depend on careful task assignment and scheduling, which further depend on utility calculation. Though there exists a number of techniques to perform efficient task allocation, they assume the utility values are available and static. They neither consider all the relevant parameters nor the dynamic changes that may occur during task execution. Moreover, methods of automating such dynamic utility calculation (both at the start and at runtime) based on knowledge and semantics are not present and this is a hindrance to building a fully automated robotic workforce. In this article, we explore an avenue of semantic-based dynamic utility calculation and showcase its application for a use-case.

Velocity Prediction Program for a Hydrofoiling Lake Racer (2022)

The aim of this paper is to develop an accurate and robust six degrees of freedom stationary velocity prediction program (VPP) applied to a high-performance sailing yacht. The model is set up to assist NC Raceboats with the VPP based hydrofoil design, considering the sailing performance in three modes: displacement, transition and hydrofoil. The yacht is a lightweight monohull designed for light wind conditions with up to five crew members. The design includes a self-stabilizing hydrofoil configuration and an elevator rudder. The software tool, which is used for the velocity prediction program, is FS-Equilibrium, developed by DNV. The software offers a modular workbench in which each force can be modelled with semi-empirical force modules, which are based on validated methods and theories. The performance prediction is interpreted and discussed: as foreseen, the performance of the high-performance lake racer in hydrofoiling condition is significantly improved compared to its assessment in displacement sailing mode. In medium breeze conditions, the yacht is able to lift up on its hydrofoils and attain flight mode. The minimum hydrofoiling speed investigation demonstrates that the VPP is able to consistently iterate Through the transition mode. This paper shows that it is possible to develop a VPP model for a hydrofoiling sailing yacht on the basis of relatively simple assumptions and theories.
