Expression and Distribution of Phosphodiesterase Isoenzymes in the Human Seminal Vesicles (2011)

The results indicate that cyclic AMP- and cyclic GMP-PDE isoenzymes are involved in the control of secretory activity and efferent neurotransmission in the SV. These findings might be of importance with regard to the identification of new therapeutic avenues to treat premature ejaculation.
Evidence for the Prion Hypothesis: Induction of the Yeast [ <i> PSI <sup>+</sup> </i> ] Factor by in Vitro- Converted Sup35 Protein (2000)

Starting with purified, bacterially produced protein, we have created a [PSI(+)]-inducing agent based on an altered (prion) conformation of the yeast Sup35 protein. After converting Sup35p to its prion conformation in vitro, we introduced it into the cytoplasm of living yeast using a liposome transformation protocol. Introduction of substoichiometric quantities of converted Sup35p greatly increased the rate of appearance of the well-characterized epigenetic factor [PSI+], which results from self-propagating aggregates of cellular Sup35p. Thus, as predicted by the prion hypothesis, proteins can act as infectious agents by causing self-propagating conformational changes.
Fracture Mechanics Evaluation of Pipes Subjected to Combined Load Conditions (2009)

For certain applications, pipelines may be submitted to biaxial loading situations. In these cases, it is not clear the influence of the biaxial loading on the fracture mechanics behavior of cracked pipelines. For further understanding of biaxial loading effects, this work presents a numerical simulation of ductile tearing in a circumferentially surface cracked pipe under biaxial loading using the computational cell methodology. The model was adjusted with experimental results obtained in laboratory using single edge cracked under tension (SENT) specimens. These specimens appear as the better alternative to conventional fracture specimens to characterize fracture toughness of circumferentially cracked pipes. The negligible effect of biaxial loadings on resistance curves was demonstrated. To guarantee the similarities of stress and strains fields between SENT specimens and cracked pipes subjected to biaxial loading, a constraint study using the J-Q methodology and the h parameter was used. The constraint study gives information about the characteristics of the crack-tip conditions.

Degradation of Phospholipid Transfer Protein (PLTP) and PLTP-generated Pre-β-high Density Lipoprotein by Mast Cell Chymase Impairs High Affinity Efflux of Cholesterol from Macrophage Foam Cells (2003)

Human atherosclerotic lesions contain mast cells filled with the neutral protease chymase. Here we studied the effect of human chymase on (i) phospholipid transfer protein (PLTP)-mediated phospholipid (PL) transfer activity, and (ii) the ability of PLTP to generate pre-beta-high density lipoprotein (HDL). Immunoblot analysis of PLTP after incubation with chymase for 6 h revealed, in addition to the original 80-kDa band, four specific proteolytic fragments of PLTP with approximate molecular masses of 70, 52, 48, and 31 kDa. This specific pattern of PLTP degradation remained stable for at least 24 h of incubation with chymase. Such proteolyzed PLTP had reduced ability (i) to transfer PL from liposome donor particles to acceptor HDL(3) particles, and (ii) to facilitate the formation of pre-beta-HDL. However, when PLTP was incubated with chymase in the presence of HDL(3), only one major cleavage product of PLTP (48 kDa) was generated, and PL transfer activity was almost fully preserved. Moreover, chymase effectively depleted the pre-beta-HDL particles generated from HDL(3) by PLTP and significantly inhibited the high affinity component of cholesterol efflux from macrophage foam cells. These results suggest that the mast cells in human atherosclerotic lesions, by secreting chymase, may prevent PLTP-dependent formation of pre-beta-HDL particles from HDL(3) and so impair the anti-atherogenic function of PLTP.
Stretchable conductive fabric simplifies manufacturing of low-resistance dielectric-elastomer-system electrodes (2018)

We made low-resistance electrodes for a dielectric elastomer system (DES) without the use of thin film deposition or wet lab processes by utilizing a stretchable conductive fabric, Less EMF Stretch Conductive Fabric (SCF), for electrode material. Carbon-based DES electrodes are easy to make, but they have high resistances (kilo ohms) that hamper dynamic operation and reduce energy efficiency. Metal and hydrogel DES electrodes have much lower resistances (tens to hundreds of ohms), but they require complex manufacturing processes, such as thin film deposition or wet lab synthesis. Conductive fabrics can have low resistance and they can be made into DES electrodes with merely a laser cutter and a dry lab environment, but their stiffness may hinder DES performance. This work reports electrical and mechanical properties of SCF and a more compliant, though less conductive fabric, MedTex P70+B, and describes the assembly and performance of DES variable stiffness modules using them. SCF had low sheet resistance, less than 3.0 ohm/square even during 125% biaxial stretch, and both fabrics stretched beyond 200 % uniaxial elongation before mechanical failure. The assembly of modules with conductive fabric electrodes was comparable in terms of difficulty to that with carbon powder electrodes, and produced functional modules. However, the stiffness of the fabrics diminished DES stiffness-reduction performance to merely 12.8 % and 13.4 % compared to the 24.5 % stiffness reduction a DES module with carbon powder electrodes achieved. Future work should investigate or develop more compliant conductive fabrics that would yield greater DES performance.
A Pressurized Air Receiver for Solar-driven Gas Turbines (2014)

A pressurized air-based solar receiver is considered for power generation via gas turbines using concentrated solar energy. The modular solar receiver is designed for heating compressed air to the entrance conditions of a gas turbine in the pressure range 4 – 30 bar and temperature range 800 – 1200 °C. The development work involved the design, fabrication, testing, and modelling of a 3 kWth and a 35 kWth solar receiver prototypes. System integration of an array of modular solar receivers with fossil-fuel hybridization was analysed.
Giant Fluctuations and Gate Control of the <i>g</i>-Factor in InAs Nanowire Quantum Dots (2008)

We study the g-factor of discrete electron states in InAs nanowire based quantum dots. The g values are determined from the magnetic field splitting of the zero bias anomaly due to the spin 1/2 Kondo effect. Unlike to previous studies based on 2DEG quantum dots, the g-factors of neighboring electron states show a surprisingly large fluctuation: g can scatter between 2 and 18. Furthermore electric gate tunability of the g-factor is demonstrated.
Neural Graphics Pipeline for Controllable Image Generation (2020)

We present Neural Graphics Pipeline (NGP), a hybrid generative model that brings together neural and traditional image formation models. NGP generates coarse 3D models that are fed into neural rendering modules to produce view-specific interpretable 2D maps, which are then composited into the final output image using a traditional image formation model. Our approach offers control over image generation by providing direct handles controlling illumination and camera parameters, in addition to control over shape and appearance variations. The key challenge is to learn these controls through unsupervised training that links generated coarse 3D models with unpaired real images via neural and traditional (e.g., Blinn-Phong) rendering functions without establishing an explicit correspondence between them. We evaluate our hybrid modeling framework, compare with neural-only generation methods (namely, DCGAN, LSGAN, WGAN-GP, VON, and SRNs), report improvement in FID scores against real images, and demonstrate that NGP supports direct controls common in traditional forward rendering. Code, data, and trained models will be released on acceptance.

Modification of cystatin C activity by bacterial proteinases and neutrophil elastase in periodontitis. (1997)

The physiological control of cathepsin B activity is impeded in periodontitis, owing to the release of proteinases from infecting P gingivalis and neutrophils, with a contribution to the tissue destruction seen in periodontitis as a probable consequence.
Trapping cavitation bubbles with a self-focused laser beam (2004)

We observed that laser-induced cavitation bubbles in water can be trapped in a self-focused laser beam. Both optical imaging and acoustic detection have been utilized to confirm bubble trapping. Transverse and longitudinal trapping forces were measured to be as large as 87 and 11 pN, respectively. This result is contrary to conventional wisdom, since the mechanism of trapping in conventional optical tweezers implies that a low-index particle (a bubble being the limiting case) should be antitrapped.
Influence of polyelectrolyte capillary coating conditions on protein analysis in CE (2009)

CE of biomolecules is limited by analyte adsorption on the capillary wall. To prevent this, monolayer or successive multiple ionic-polymer layers (SMILs) of highly charged polyelectrolytes can be physically adsorbed on the inner capillary surface. Although these coatings have become commonly used in CE, no systematic investigation of their performance under different coating conditions has been carried out so far. In a previous study (Nehmé, R., Perrin, C., Cottet, H., Blanchin, M. D., Fabre, H., Electrophoresis 2008, 29, 3013-3023), we investigated the influence of different experimental parameters on coating stability, repeatability and peptide peak efficiency. Optimal coating conditions for monolayer and multilayer (SMILs) poly(diallyldimethylammonium) chloride/ poly(sodium 4-styrenesulfonate) coated capillaries were determined. In this study, the influence of polyelectrolyte concentration and ionic strength of the coating solutions, and the number of coating layers on coating stability and performance in limiting protein adsorption was carried out. EOF magnitude and repeatability were used to monitor coating stability. Coating ability to limit protein adsorption was investigated by monitoring variations of migration times, time-corrected peak areas and separation efficiency of test proteins. The separation performance of polyelectrolyte coatings were compared with those obtained with bare silica capillaries.
Alterations in the proteome of pulmonary alveolar type II cells in the rat after hepatic ischemia-reperfusion (2008)

The proteins identified by quantitative proteomics indicated significant changes in moderators of cell metabolism and host defense in ATII. These findings provide new insights into possible mechanisms responsible for hepatic ischemia-reperfusion-related acute lung injury and suggest that ATII cells in the lung sense and respond to hepatic injury.
Bent Sequences over Hadamard Codes for Physically Unclonable Functions (2021)

We study challenge codes for physically unclonable functions (PUFs). Starting from the classical Hadamard challenge code, we augment it by one vector. Numerical values suggest that the optimal choice of this vector for maximizing the entropy is to pick a vector the farthest away from the code formed by the challenges and their binary complements. This leads us to study the covering radius of Hadamard codes. A notion of bent sequence that generalizes the classical notion from Hadamard matrices of Sylvester type to general Hadamard matrices is given. Lower bounds for Paley-type Hadamard matrices are given.
Dual Emissions from Ruthenium(II) Complexes Having 4-Arylethynyl-1,10-phenanthroline at Low Temperature (2015)

A [Ru(phen)3](2+) complex (phen = 1,10-phenanthroline) having an arylethynyl group at the 4-position of one of the three phen ligands (aryl: (dimesityl)borylduryl group = [RuBE](2+) or duryl group = [RuDE](2+)) showed dual emissions at low temperature in propylene carbonate (PC). The shorter emission lifetime components (τ(em)(s) ≈ 13 μs) that originated from the lowest-energy excited triplet states (T1) of the complexes were almost independent of temperature (T = 77-320 K), while the longer emission lifetime components (τ(em)(l)), as the T2 emissions appeared below the fluid-to-glass transition temperature (Tg ≈ 220 K) in PC, were almost constant at 27 μs in the range of T = 77-220 K. The τ(em)(s) components of the complexes were assigned to the emissions from the metal-to-ligand charge transfer (MLCT) excited states possessing relatively large ligand-centered (LC) excited-state characters (T1(MLCT/LC)), while the τ(em)(l) components were shown to be originating from the T2(MLCT) excited states. The T2(MLCT) states of the complexes became nonemissive above Tg in PC due to fast nonradiative decay through solvent reorganization around the T2(MLCT) excited states. The photophysical properties of the complexes were also shown to be characterized by the presence of the arylethynyl units at the 4-positions of the phen ligands.

RDF models for dynamic syndication and wireless applications (2001)

Variations in brain gray matter volume and density have been reported in association with a variety of disorders characterized by chronic pain, including chronic low back pain, fibromyalgia, and irritable bowel syndrome. Correlation analyses have demonstrated relationships between morphometric and clinical variables. However, conclusions regarding the nature of these relationships are problematic given that currently available data are derived exclusively from cross-sectional studies. Further efforts to determine the relationship between chronic pain and variations in brain morphometry will depend in part on longitudinal studies of patients at various stages of illness, as well as those at risk of the development of chronic pain. Interpretation of findings from morphometric studies also must take into account genetic and experiential factors that recently have been demonstrated to influence brain morphometry and the risk of developing chronic pain.
Crystal Structures of the Fluorinated Fullerenes C<sub>60</sub>F<sub>36</sub> and C<sub>60</sub>F<sub>48</sub> (1999)

To elucidate the structures of C60F36 and C60F48, X-ray diffraction and electron diffraction experiments have been performed. It was found that the X-ray diffractograms of C60F36 and C60F48 at room temperature are indexed by bcc and bct lattices, respectively. In situ X-ray diffraction experiments at high temperatures have been also undertaken. The bct to fcc phase transition of C60F48 was observed. The mechanism of the transition and the stabilities of the structures of fluorinated fullerenes are discussed.
Paradoxos organizacionais, gestão de pessoas e tecnologia na Souza Cruz (2004)

Pesquisas sobre o atual contexto da gestão de pessoas no Brasil indicam uma importante fase de transição pela qual a área de RH passa atualmente, de uma atuação predominantemente operacional para modelos mais orgânicos de gestão de pessoas. Os autores pesquisados mostram que a aprendizagem organizacional é uma variável progressivamente defendida e valorizada pelos profissionais da área nos novos modelos de gestão que emergem no Brasil. Esta época de transição de modelos tem como característica a intensificação de paradoxos e contradições nas organizações, que adotam rapidamente o novo discurso, mas encontram dificuldades operacionais para implementação das novas estruturas e comportamentos próprios aos novos modelos. Mostrados por meio de um estudo de caso como a organização estudada conseguiu evitar os efeitos do paradoxo discurso x prática gerencial por meio da emergência do modelo político de gestão de pessoas. Na medida em que mudanças graduais permitiram a construção de novas competências e novos relacionamentos necessários à implementação de sistemas de informação, consolidou-se um novo sistema organizacional, mais propício à aprendizagem.
SURFACE MORPHOLOGY AND MICROSTRUCTURAL CHARACTERIZATION OF <font>KCl</font> CRYSTALS GROWN IN HALITE–SYLVITE BRINE SOLUTIONS BY ELECTRON BACKSCATTERED DIFFRACTION TECHNIQUES (2014)

In this paper, a study on the ternary NaCl – KCl – H 2 O system was carried out by an extractive metallurgy technique from mixed brine solutions of different compositions at room temperature (23°C). The surface morphology and microstructure were examined using a scanning electron microscope (SEM), electron backscattered diffraction (EBSD) and an energy dispersive X-ray (EDX) spectroscopy. The presence of [Formula: see text] was found to reduce the stability of the solutions and increase the crystallization induction period, interfacial energy, energy of formation of the nucleus and greatly reduce the nucleation rate of KCl crystal. The surface morphology of KCl crystals is significantly changed due to presence of 5 to 10% (w/w) of NaCl as impurities in the binary solutions and shows the formation of co-crystals of different crystallographic orientation of NaCl on the KCl surface. In addition X-ray diffraction studies performed on KCl crystals grown in halite–sylvite binary solutions reveals that these crystals are cubic in nature and its lattice constant is 6.2952 Å when the NaCl concentration is small.
Xen 2002 (2003)

This report describes the design of Xen, the hypervisor developed as part of the XenoServer wide-area computing project. Xen enables the hardware resources of a machine to be virtualized and dynamically partitioned such as to allow multiple different `guest’ operating system images to be run simultaneously. Virtualizing the machine in this manner provides flexibility, allowing different users to choose their preferred operating system (Windows, Linux, NetBSD), and also enables use of the platform as a testbed for operating systems research. Furthermore, Xen provides secure partitioning between these `domains’, and enables better resource accounting and QoS isolation than can be achieved within a conventional operating system. We show these benefits can be achieved at negligible performance cost. We outline the design of Xen’s main sub-systems, and the interface exported to guest operating systems. Initial performance results are presented for our most mature guest operating system port, Linux 2.4. This report covers the initial design of Xen, leading up to our first public release which we plan to make available for download in April 2003. Further reports will update the design as our work progresses and present the implementation in more detail.

Investigation of Lysine-Functionalized Dendrimers as Dichlorvos Detoxification Agents (2015)

Lysine-containing polymers have seen broad application due to their amines' inherent ability to bind to a range of biologically relevant molecules. The synthesis of multiple generations of polyester dendrimers bearing lysine groups on their periphery is described in this report. Their hydrolytic stabilities with respect to pH and time, their toxicity to a range of cell lines, and their possible application as nano-detoxification agents of organophosphate compounds are all investigated. These zeroth-, first-, and second-generation water-soluble dendrimers have been designed to bear exactly 4, 8, and 16 lysine groups, respectively, on their dendritic periphery. Such monodisperse bioactive polymers show potential for a range of applications including drug delivery, gene delivery, heavy metal binding, and the sequestration of organic toxins. These monodisperse bioactive dendrimers were synthesized using an aliphatic ester dendritic core (prepared from pentaerythritol) and protected amino acid moieties. This library of lysine-conjugated dendrimers showed the ability to efficiently capture the pesticide dichlorvos, confirming the potential of dendrimer-based antidotes to maintain acetylcholinesterase activity in response to poisoning events.
