Comparative Normal Mode Analysis of the Dynamics of DENV and ZIKV Capsids (2016)

Key steps in the life cycle of a virus, such as the fusion event as the virus infects a host cell and its maturation process, relate to an intricate interplay between the structure and the dynamics of its constituent proteins, especially those that define its capsid, much akin to an envelope that protects its genomic material. We present a comprehensive, comparative analysis of such interplay for the capsids of two viruses from the <i>flaviviridae</i> family, Dengue (DENV) and Zika (ZIKV). We use for that purpose our own software suite, DD-NMA, which is based on normal mode analysis. We describe the elements of DD-NMA that are relevant to the analysis of large systems, such as virus capsids. In particular, we introduce our implementation of simplified elastic networks and justify their parametrization. Using DD-NMA, we illustrate the importance of packing interactions within the virus capsids on the dynamics of the E proteins of DENV and ZIKV. We identify differences between the computed atomic fluctuations of the E proteins in DENV and ZIKV and relate those differences to changes observed in their high resolution structures. We conclude with a discussion on additional analyses that are needed to fully characterize the dynamics of the two viruses.
A Methodology to Analyze and Evaluate the Uncertainty Propagation due to Temperature and Frequency and Design Optimization for EMC Testing Instrumentation (2021)

This paper presents a study and proposes a new methodology to analyze, evaluate and reduce the overall uncertainty of instrumentations for EMC measurements. For the scope of this work, the front end of a commercial EMI receiver is chosen and variations due to tolerances, temperature and frequency response of the system are evaluated. This paper illustrates in detail how to treat each block composing the model by analyzing each discrete component, and how to evaluate their influence on the measurand. Since a model can have hundreds or even thousands of parameters, the probability distribution functions (PDFs) of some variable might be unknown. So, a method that allows to obtain in a fast and easy way the uncertainty of the measurement despite having so many variables, to then being able to evaluate the influence of each component on the measurand, is necessary for a correct design. In this way, it will be possible to indicate which discrete components have the most influence on the measurand and thus set the maximum tolerances allowed and being able to design a cost-effective solution. Furthermore, this works presents a methodology which can easily be extended and applied to estimate and compute the uncertainty for electromagnetic interferences, energy storage systems (ESS), energy production, electric machines, electric transports and power plants in general.
MID Max: LC–MS/MS Method for Measuring the Precursor and Product Mass Isotopomer Distributions of Metabolic Intermediates and Cofactors for Metabolic Flux Analysis Applications (2015)

The analytical challenges to acquire accurate isotopic data of intracellular metabolic intermediates for stationary, nonstationary, and dynamic metabolic flux analysis (MFA) are numerous. This work presents MID Max, a novel LC-MS/MS workflow, acquisition, and isotopomer deconvolution method for MFA that takes advantage of additional scan types that maximizes the number of mass isotopomer distributions (MIDs) that can be acquired in a given experiment. The analytical method was found to measure the MIDs of 97 metabolites, corresponding to 74 unique metabolite-fragment pairs (32 precursor spectra and 42 product spectra) with accuracy and precision. The compounds measured included metabolic intermediates in central carbohydrate metabolism and cofactors of peripheral metabolism (e.g., ATP). Using only a subset of the acquired MIDs, the method was found to improve the precision of flux estimations and number of resolved exchange fluxes for wild-type E. coli compared to traditional methods and previously published data sets.
Pharmacodynamic Evaluation of the Neutralization of Endotoxin by PMX622 in Mice (2004)

Polymyxin B (PMB) binds to and neutralizes endotoxin, but its systemic clinical utility is limited by neuro- and nephrotoxicity. PMX622 is a covalent conjugate of PMB and Dextran-70 designed to retain the ability of PMB to neutralize endotoxin and to retain the favorable colloidal, pharmacokinetic, and metabolic properties of Dextran-70. PMX622 has demonstrated efficacy in a number of animal models and effectively neutralized endotoxin in phase I clinical trials. Here, we systematically evaluated the pharmacodynamic properties of PMX622 in a murine model of endotoxin-induced lethality in galactosamine-sensitized mice. PMX622 completely and dose dependently inhibited lethality in this model. A stoichiometric relationship was found between the endotoxin challenge dose and the dose of PMX622 needed for protection. PMX622 neutralized endotoxin from four different genera of gram-negative bacteria but not Neisseria meningitidis. PMX622 was significantly less toxic than PMB in the mouse, suggesting that PMX622 has a better margin of safety than PMB. The timing of PMX622 administration relative to endotoxin was crucial. PMX622 was active for several hours prior to the endotoxin challenge; however, PMX622 did not protect mice if administered >/=15 min after endotoxin challenge. This suggests that PMX622 would best be clinically used prophylactically rather than therapeutically. These studies will be crucial in designing and interpreting human clinical trials assessing PMX622 efficacy.
0200 The Impact Of Video Gaming On Training Future Orthopaedic Surgeons – Does Play Correlate With Skill? (2014)

Background Studies have postulated the extent of video gaming exposure and the correlation with surgical skills acquisition and visuospatial awareness. No study has examined the link between extent of video-gaming and performance on a orthopaedic trauma simulator. Objectives To assess whether video-gaming improves performance on a virtual-reality (VR) dynamic hip screw (DHS) fixation for an extra capsular fracture of the left neck of femur. Methodology 38 medical students, naive to VR surgical simulation, were recruited and stratified according to their exposure to video gaming. Group 1 (n = 19, video-gamers) were defined as those who play more than one hour per day in the last year, Group 2 (n = 19, non-gamers) were defined as those who play video games less than one hour per year. Both cohorts performed five attempts on completing a VR DHS and repeated the task after a week. The VR simulator recorded six real-time objective performance metrics. Mean scores were calculated and Mann-Whitney U tests were used to calculate significance (p Results The groups were not significantly different at baseline indicating heterogenous populations to minimise selection bias. After ten attempts, Group 1 were not significantly better than Group 2 in time, fluoroscopy, number of radiographs, number of retries, tip-apex distance, percentage cut-out, and global score. Conclusions Contrary to previous findings in literature, there was no difference between those with extensive video gaming experience and those without similar gaming exposure in regards to gaining competency on a VR orthopaedic trauma simulator. This is the first study to document there being no advantage of playing video games in order to achieve competency on this VR DHS simulator. This study showed that the VR application will neither be affected by previous hand-eye coordination practice nor is there a transferability of generic skills from video-gaming to the VR DHS simulator.

An analytic study of the effects of attenuation on tumor detection in whole-body PET oncology imaging. (2003)

Even though images without attenuation correction may be desired, these results suggest that all studies should at least be reconstructed with attenuation correction to avoid missing regions of elevated tracer uptake.
Cantilever array for measuring traction forces of cells in a confined space (2017)

This paper reports a sensor to directly measure the traction forces generated by migrating cells in a confined space. The sensor consists of an array of miniaturized piezoresistive cantilevers which are surrounded by a pluronic-F127 pattern. The pattern allows the self-alignment and directional migration of the cells to the cantilever array as the adhesion of cells to pluronic-F127 is poor. Our method enables the quantitative evaluation of the traction forces of cells with controlled migrating direction.

A low-power CMOS integrated sensor for CO<inf>2</inf> detection in the percentage range (2013)

Within the Catrene project “PASTEUR”, a low-cost, low-power capacitive carbon dioxide sensor has been developed for tracking CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> concentration in the percentage range. This paper describes this sensor, which operates at room temperature where it exhibits short response times as well as reversible behavior. It can be easily integrated using CMOS compatible processing, and has been combined with a Relative Humidity (RH) sensor, using the same capacitive transduction method, and with a low-power capacitance-to-digital converter, hence enabling correction of cross sensitivity to RH.
Microwave-Accelerated SPOT-Synthesis on Cellulose Supports (2004)

[reaction: see text] We demonstrate that microwave irradiation can dramatically accelerate reaction rates for spatially addressable library synthesis on planar membrane supports. The development of a robust support/linker system, microwave-assisted synthesis of small molecule test libraries, and methods for solid-phase scale-up on cellulose are described.
Annual Report for Ocean Acoustics (2013)

Abstract : One of the long-term goals of this project is to analyze and propose energy-efficient communication techniques for underwater acoustic sensor networks. These techniques aim at consuming as less energy as possible as well as guaranteeing a minimum quality of service. In order to do so, we assume and validate some statistics of the underwater acoustic channels and derive stochastic optimal transmission policies. Another long-term goal of this project is to investigate the possibility that these underwater acoustic networks disrupt the behavior of surrounding species of marine mammals. As a consequence of these two studies, we aim at developing minimally disruptive communication schemes.
Accurate density functional thermochemistry for larger molecules (1997)

Density functional methods are combined with isodesmic bond separation reaction energies to yield accurate thermochemistry for larger molecules. Seven different density functionals are assessed for the evaluation of heats of formation, Delta H 0 (298 K), for a test set of 40 molecules composed of H, C, O and N. The use of bond separation energies results in a dramatic improvement in the accuracy of all the density functionals. The B3-LYP functional has the smallest mean absolute deviation from experiment (1.5 kcal mol/f).
Sugars, Starches and Cellulose Products (2018)

Carbohydrates are a group of organic compounds containing carbon, hydrogen and oxygen generally in the ratio of 1:2:1.The comparatively high percentage of oxygen makes carbohydrates a less efficient source of energy than fats and oils. They may be divided roughly into three groups; monosaccharides, oligosaccharides and polysaccharides.
Oxygen permeability of biodegradable copolycaprolactones (1999)

Polycaprolactone is one of the biodegradable polymers with good drug permeability. In the present paper, polycaprolactone and three kinds of copolycaprolactone–polycaprolactone–poly(ethylene oxide)– polycaprolactone triblock copolymer (PCE), polycaprolactone/polycaprolactone-poly(ethylene oxide)/polylactide tricomponents random block copolymer (PCEL) and polycaprolactone/poly(ethylene terephthalate) random block copolymer (PETCL)– were synthesized. The biodegradation behavior of these polymers were shown by degradation tests in vitro, ex vivo and in vivo. The oxygen permeabilities of these polymers were in the range of 10−10 ∼ 10−9 cm3 (STP) cm/cm2 sec cm Hg. Copolymers PCE and PCEL displayed O2 and N2 permeability coefficients (PO2/PN2) ratios of about 9. The effects of composition and crystallinity of the copolymers on biodegradability and the oxygen permeability of the polymer were discussed. Copyright © 1999 John Wiley & Sons, Ltd.
<title>Application of frequency domain techniques to samples with moderate scatter</title> (1999)

We show that the optical properties of a sample with moderate scatter can be obtained by performing frequency domain measurements in a reflection geometry. In experiments and Monte Carlo simulations we show that absorption and scatter produce opposing trends in the amplitude signal and common trends in the phase signal. Therefore a measured amplitude and phase signal correspond to a unique combination of optical properties for a given phase function.
Pairwise View Weighted Graph Network for View-based 3D Model Retrieval (2020)

View-based 3D model retrieval has become an important task in both computer vision and machine learning domains. Although deep learning methods have achieved excellent performances on view-based 3D model retrieval, the intrinsic correlation and the degree of view discrimination among multiple views in a 3D model have not been effectively exploited. To obtain a more efficient feature descriptor for 3D model retrieval, in this work, we propose the pairwise view weighted graph network (abbreviated PVWGN) for view-based 3D model retrieval where non-local graph layers are embedded into the network architecture to automatically mine the intrinsic relationship among multiple views of a 3D model. Furthermore, the view weighted layer is employed in the PVWGN to adaptively assign the weight to each view according to its aggregation information. In addition, the pairwise discrimination loss function is designed to improve the feature discrimination of the 3D model. Most importantly, these three issues are integrated into a unified framework. Extensive experimental results on the ModelNet40 and ModelNet10 3D model retrieval datasets show that PVWGN can outperform all state-of-the-art methods on the 3D model retrieval task with mAPs of 93.2% and 96.2%, respectively.
Quantum Interference in Acyclic Systems: Conductance of Cross-Conjugated Molecules (2008)

We calculate that significant quantum interference effects can be observed in elastic electron transport through acyclic molecules. Interference features are evident in the transmission characteristics calculated for cross-conjugated molecules; significantly, these effects dominate the experimentally observable conduction range. The unusual transport characteristics of these molecules are highlighted through comparison with linearly conjugated and nonconjugated systems. The cross-conjugated molecules presented here show a large dynamic range in conductance. These findings represent a new motif for electron transfer through molecules that exhibit both very high and very low tunneling conductance states accessible at low bias without nuclear motion. In designing single molecule electronic components, a large dynamic range allows a high on/off ratio, a parameter of fundamental importance for switches, transistors, and sensors.
Multi data rate signaling based on IEEE 802.15.4 (2010)

The IEEE 802.15.4 standard was brought up for the use in wireless personal area networks (WPANs) and is widely known as ZigBee. It employs spread spectrum techniques to obtain a robust transmission at comparatively low data rates of up to 250 kbit/s. In order to better match a certain transmission environment, different spreading factors could be used to obtain additional data rate modes. This approach appears to be a feasible extension to IEEE 802.15.4 allowing the coverage of a wider range of the signal to interference and noise ratio (SINR). However, a signaling scheme must be added to distinguish the additional modes from the native ZigBee mode. This scheme should also allow the operation of extended devices without interfering native ZigBee devices. Based on the structure of an IEEE 802.15.4 frame a method is presented that will allow extending the specified frame structure to a multi data rate system without interfering IEEE 802.15.4 compliant devices.
Photonic Generation, Wireless Transmission, and Detection of Continuously Tunable Chirped Millimeter-Wave Waveforms with Ultra-High Compression Ratio at W-band (2012)

By using fast-sweeping fiber distributed Bragg reflector lasers and wideband/high-power photonic transmitter-mixers at W-band, continuously tunable chirped millimeter-wave waveforms generation, wireless transmission, and detection with record-high compression ratio (89-103 GHz/50µs/7×105) can be achieved.
The effect of the length of a malarial epitope on its antigenicity and immunogenicity in an epitope presentation system using the Pseudomonas aeruginosa outer membrane protein OprF as the carrier (1996)

This study showed that the antigenicity of a malarial epitope increased with the length of the epitope when inserted at positions aa26 (amino acid position 26) and aa196, but not at aa213, of the Pseudomonas aeruginosa major outer membrane protein OprF (326 amino acids). Immunization studies showed that a 19-aa epitope was significantly more immunogenic than a 7-aa epitope when inserted at aa26 of OprF, while neither an 11 — nor a 19-aa epitope fused to the C-terminus of glutathione S-transferase was immunogenic.
Functional characterization of thioredoxin 3 (TRX-3), a Caenorhabditis elegans intestine-specific thioredoxin (2013)

Thioredoxins are a class of evolutionarily conserved proteins that have been demonstrated to play a key role in many cellular processes involving redox reactions. We report here the genetic and biochemical characterization of Caenorhabditis elegans TRX-3, the first metazoan thioredoxin with an intestine-specific expression pattern. By using green fluorescent protein reporters we have found that TRX-3 is expressed in both the cytoplasm and the nucleus of intestinal cells, with a prominent localization at the apical membrane. Although intestinal function, reproductive capacity, longevity, and resistance of trx-3 loss-of-function mutants to many stresses are indistinguishable from those of wild-type animals, we have observed a slight reduction in size and a minor reduction in the defecation cycle timing of trx-3 mutants. Interestingly, trx-3 is induced upon infection by Photorhabdus luminescens and Candida albicans, and TRX-3 overexpression provides a modest protection against these pathogens. Together, our data indicate that TRX-3 function in the intestine is dispensable for C. elegans development but may be important to fight specific bacterial and fungal infections.
ChemInform Abstract: Synthesis of Novel Fluoropicolinate Herbicides by Cascade Cyclization of Fluoroalkyl Alkynylimines. (2015)

Abstract Evaluation of the protecting groups leads to the identification of N‐trityl‐5,5‐diethoxy protected 1,1,1‐trifluoropent‐3‐yn‐2‐imine as suitable precursors for the cyclization with aryl and alkyl substituted methylamines and subsequent deprotection to 2‐substituted picolinaldehydes.
Fcγ receptor polymorphisms in relation to periodontitis (2003)

The current study of relative small sample size suggests that the FcgammaRIIa-H/H131 genotype may be a putative susceptibility and severity factor, and the FcgammaRIIIa-V158 allele a putative susceptibility factor for periodontitis in Northern European Caucasians. These results need further verification and the biological importance of these findings needs further investigation.
Recent Developments in Palladium-Catalyzed Oxidative Cascade Carbocyclization (2017)

In this Perspective, we describe recent advances on Pd-catalyzed oxidative cascade carbocyclizations. These cascade processes enable efficient construction of the molecular complexity and structural diversity of carbocyclic compounds via introducing diverse functionalities concomitant with multiple C–C bond-formations in one-pot operations. In many cases, these processes are facilitated by Pd-catalysts alone, while cocatalysis by combination of Pd catalyst and other catalysts are also discussed, since they represent a new entry to address the preparation of functionalized cyclic compounds with high efficiency and selectivity.
Faults of ZnO Crystal in ZnO Varistor. (1994)

Formation of faults in ZnO grain by addition of some metal oxides were studied . Two kinds of faults were observed in non-ohmic polycrystalline ZnO (ZnO varistor): one is twin-type and the other is stacking-type. ZnO grains having twin structures were obsereved with specimens prepared
