ContentsRsum en Franais HDR.Tandis que la premire mthode utilise un espace de couleur Y'CbCr, ce qui est la reprsentation la plus courante pour la compression vido, la seconde mthode dfinit un espace de couleur alternatif dcoulant directement des principes de colorimtrie dcrits au premier chapitre.Outre les avantages que cela confre pour la compression de contenu HDR, les proprits de cet espace de couleur permettent une prdiction inter-couches plus simple et plus prcise des composantes chromatiques que dans le cas de l'espace Y'CbCr.Chapter 2 : The second chapter presents the field of image and video compression.After describing the general concepts of decorrelation, quantization and entropy encoding, we explain how they are applied to block-based video codecs.In particular, we provide an overview of the main tools in the new HEVC standard.The question of the compression of HDR content is also raised and the main types of architectures for HDR coding systems are outlined in the last section of the chapter.Chapter 3 : In this first contribution chapter, we tackle the problem of backward compatibility with single layer methods from the angle of the rate-distortion performance.This problem is then to find the best way to reduce the bitdepth of an HDR image so that it can be compressed by a conventional low bitdepth encoder with minimal distortion at a given bitrate.A first work studies the adaptation of a simple uniform quantization technique to the content of either individual blocks, frames or several consecutive frames of a sequence.We show that those variants of the method are adapted
African Swine Fever Virus Undergoes Outer Envelope Disruption, Capsid Disassembly and Inner Envelope Fusion before Core Release from Multivesicular Endosomes (2016)

African swine fever virus (ASFV) is a nucleocytoplasmic large DNA virus (NCLDV) that causes a highly lethal disease in domestic pigs. As other NCLDVs, the extracellular form of ASFV possesses a multilayered structure consisting of a genome-containing nucleoid successively wrapped by a thick protein core shell, an inner lipid membrane, an icosahedral protein capsid and an outer lipid envelope. This structural complexity suggests an intricate mechanism of internalization in order to deliver the virus genome into the cytoplasm. By using flow cytometry in combination with pharmacological entry inhibitors, as well as fluorescence and electron microscopy approaches, we have dissected the entry and uncoating pathway used by ASFV to infect the macrophage, its natural host cell. We found that purified extracellular ASFV is internalized by both constitutive macropinocytosis and clathrin-mediated endocytosis. Once inside the cell, ASFV particles move from early endosomes or macropinosomes to late, multivesicular endosomes where they become uncoated. Virus uncoating requires acidic pH and involves the disruption of the outer membrane as well as of the protein capsid. As a consequence, the inner viral membrane becomes exposed and fuses with the limiting endosomal membrane to release the viral core into the cytosol. Interestingly, virus fusion is dependent on virus protein pE248R, a transmembrane polypeptide of the inner envelope that shares sequence similarity with some members of the poxviral entry/fusion complex. Collective evidence supports an entry model for ASFV that might also explain the uncoating of other multienveloped icosahedral NCLDVs.
Identification and Characterization of Vnx1p, a Novel Type of Vacuolar Monovalent Cation/H+ Antiporter of Saccharomyces cerevisiae (2007)

We identified and characterized Vnx1p, a novel vacuolar monovalent cation/H+ antiporter encoded by the open reading frame YNL321w from Saccharomyces cerevisiae. Despite the homology of Vnx1p with other members of the CAX (calcium exchanger) family of transporters, Vnx1p is unable to mediate Ca2+ transport but is a low affinity Na+/H+ and K+/H+ anti-porter with a Km of 22.4 and 82.2 mm for Na+ and K+, respectively. Sequence analyses of Vnx1p revealed the absence of key amino acids shown to be essential for Ca2+/H+ exchange. vnx1Delta cells displayed growth inhibition when grown in the presence of hygromycin B or NaCl. Vnx1p activity was found in the vacuoles and shown to be dependent on the electrochemical potential gradient of H+ generated by the action of the V-type H+-ATPase. The presence of Vnx1p at the vacuolar membrane was further confirmed with cells expressing a VNX1::GFP chimeric gene. Similar to Nhx1p, the prevacuolar compartment-bound Na+/H+ antiporter, the vacuole-bound Vnx1p appears to play roles in the regulation of ion homeostasis and cellular pH.
Comparison of deconvoluted plasma DSC curves on patients with solid tumors (2020)

Abstract Today, differential scanning calorimetry (DSC) has increasingly been an accepted method for diagnosing and monitoring different diseases. Moreover, as a highly sensitive technique it seems to be applicable in human cancer researches. Our workgroup in several previous researches has already demonstrated marked differences on DSC plasma profiles between healthy control and various tumorous patients and, in addition, at their different stages. The aim of this study was to compare deconvoluted plasma DSC curves on patients with solid tumors. Blood plasma DSC data were analyzed retrospectively from various patients, who has only local cancer diseases (malignant melanoma: n = 15, breast carcinoma: n = 10 and pancreas adenocarcinoma: n = 11) without any regional or distant metastases. The complex curves were deconvoluted in numerous individual transitions (five or seven melting points). In the examined patients with solid tumors, the thermodynamic parameters: heat flow and calorimetric enthalpy of the transitions corresponding to the most abundant plasma proteins, as well as the numbers of transitions were determined from the calorimetric profiles. Deconvoluted DSC curves from blood samples of patients showed differences and similarities at the same time in the thermal denaturation of plasma components in various carcinoma cases.
Stability and detection of recombinant pre‐pro‐concanavalin A after cytoplasmic expression in <i>Escherichia coli</i> (1992)

The cDNA for pre-pro-concanavalin A (pre-pro-Con A) from Canavalia ensiformis was used to construct two cytoplasmic expression vectors: pKconA (no transcription terminator) and pTKconA (containing the cry transcription terminator). The latter produced 2- to 3-fold greater amounts of pre-pro-Con A. This product containing the plant signal can be detected by Western blotting only after electrophoretic transfer in the presence of SDS, indicating reduced solubility. The signal is not removed and pre-pro-Con A is clearly stable after expression in E. coli JM109. The protein is not cleaved and ligated as in the plant, in contrast to a recent report.
Synthesis and Aqueous Solution Viscosity Behavior of Polyampholytes from Cationic-Anionic Monomer Pairs (1980)

This chapter reports the syntheses and viscosity behavior in aqueous salt solution of two recently prepared polyampholytes. These polymers, derived from cationic-anionic vinyl monomer pairs, exhibit viscosity behavior in salt solution that is contrary to that of normal polyelectrolytes. The intrinsic viscosity is found to increase with increasing salt concentration for one of the samples and remain virtually unchanged for the other. Also, a modified form of the Einstein-Simha equation is observed to correlate especially well with the experimental data, where, in some cases, the Huggins equation apparently is not appropriate. In the context of these findings, some previous results with regard to the behavior of a polyvinylimidazolium sulfobetaine are discussed.
Comparison of three latex agglutination kits and counterimmunoelectrophoresis for the detection of bacterial antigens in a pediatric population (1987)

Three commercial latex agglutination kits (Bactigen, Wampole Laboratories, Cranbury, NJ; Directigen, Hynson, Westcott & Dunning, Baltimore, MD; Wellcogen, Wellcome Diagnostics, Dartford, England) used for the detection of bacterial polysaccharide antigens (Haemophilus influenzae type b, Streptococcus pneumoniae, and Neisseria meningitidis) were compared with counterimmunoelectrophoresis and Gram stain for the identification of systemic bacterial disease in children. Urine and (when available) cerebrospinal fluid specimens were saved for all patients. Positive blood or cerebrospinal fluid culture isolates included 36 with H. influenzae type b, 11 with S. pneumoniae, 3 with N. meningitidis and 6 with other organisms. All latex kits performed similarly for the detection of H. influenzae type b antigen with a sensitivity range of 91 to 100%. The four methods performed poorly for the detection of S. pneumoniae (23 to 50%) and N. meningitidis (0%) antigen. Gram stain of cerebrospinal fluid appeared to be equally sensitive to the antigen detection methods for patients with meningitis. The false positive rates for the latex kits and counterimmunoelectrophoresis ranged from 2.8 to 9.2%, with Wellcogen having the lowest rates. The false negative rates ranged from 6.5% to 12% with Directigen having the lowest rate.

We report here the regioselective synthesis of aryl chalcogenides through the iridium-catalyzed meta C-H borylation followed by copper-catalyzed C-S coupling reaction with chalcogenide sources in one pot, giving the 3,5-disubstituted aryl chalcogenides with high regioselectivity and good yields.
A technique for electrically measuring the thermal resistance of GaAs bulk resistors (2002)

An electrical technique to measure the thermal resistance of GaAs bulk resistors is presented. The thermal resistance of several resistors was determined. The difference in these results relative to a liquid crystal method is discussed. Then, the reliability impact on the resistors from self-heating is studied.
Relationship between Serum Levels of Testosterone and the Severity of Chronic Obstructive Pulmonary Disease. (2012)

This study found that the prevalence of the secondary hypogonadism in COPD patients was high. The forced expiratory volume in 1 second (FEV1) was correlated with the level of serum testosterone. Further investigations are required to better evaluate the pathology and treatment of secondary hypogonadism in COPD patients.
A fabric-regulated soft robotic glove with user intent detection using EMG and RFID for hand assistive application (2016)

This paper presents a soft robotic glove designed to assist individuals with functional grasp pathologies in performing activities of daily living. The glove utilizes soft fabric-regulated pneumatic actuators that are low-profile and require lower pressure than previously developed actuators. They are able to support fingers and thumb motions during hand closure. Upon pressurization, the actuators are able to generate sufficient force to assist in hand closing and grasping during different manipulation tasks. In this work, experiments were conducted to evaluate the performances of the actuators as well as the glove in terms of its kinetic and kinematic assistance on a healthy participant. Additionally, surface electromyography and radio-frequency identification techniques were adopted to detect user intent to activate or deactivate the glove. Lastly, we present preliminary results of a healthy participant performing different manipulation tasks with the soft robotic glove controlled by surface electromyography and radio-frequency identification techniques.
Direct adenovirus-mediated gene transfer of interleukin 1 and tumor necrosis factor α soluble receptors to rabbit knees with experimental arthritis has local and distal anti-arthritic effects (1998)

Adenoviral vectors were used to deliver genes encoding a soluble interleukin 1 (IL-1)-type I receptor-IgG fusion protein and/or a soluble type I tumor necrosis factor alpha (TNFalpha) receptor-IgG fusion protein directly to the knees of rabbits with antigen-induced arthritis. When tested individually, knees receiving the soluble IL-1 receptor had significantly reduced cartilage matrix degradation and white blood cell infiltration into the joint space. Delivery of the soluble TNFalpha receptor was less effective, having only a moderate effect on white blood cell infiltration and no effect on cartilage breakdown. When both soluble receptors were used together, there was a greater inhibition of white blood cell infiltration and cartilage breakdown with a considerable reduction of synovitis. Interestingly, anti-arthritic effects were also seen in contralateral control knees receiving only a marker gene, suggesting that sustained local inhibition of disease activity in one joint may confer an anti-arthritic effect on other joints. These results suggest that local intra-articular gene transfer could be used to treat systemic polyarticular arthritides.
Combining various solution techniques for dynamic fault tree analysis of computer systems (2002)

Fault trees provide a conceptually simple modeling framework to represent system-level reliability in terms of interactions between component reliabilities. DIFtree (Dynamic Innovative Fault trees) effectively combines the best static fault tree solution technique (binary decision diagrams) with Markov solution techniques for dynamic fault trees. DIFtree includes advanced techniques for modeling coverage; coverage modeling has been shown to be critical to the analysis of fault-tolerant computer systems. DIFtree is based on a divide-and-conquer technique for modularizing the system-level fault tree into independent sub-trees; different solution techniques can be used for sub-trees. In this paper, we extend the DIFtree analysis capability to model several different distributions of time-to-failure, including fixed probabilities (no time component), exponential (constant hazard rate), Weibull (time-varying hazard rate) and log-normal. Our approach extends both the BDD and Markov analytical approaches and incorporates simulation as well.
Cross-property relations between electrical conductivity and the seismic velocity of rocks (2007)

Abstract Cross-property relations are useful when some rock properties can be measured more easily than other properties. Relations between electrical conductivity and seismic velocity, stiffness moduli, and density can be obtained by expressing the porosity in terms of those properties. There are many possible ways to combine the constitutive equations to obtain a relation, each one representing a given type of rock. The relations depend on the assumptions to obtain the constitutive equations. In the electromagnetic case, the equations involve Archie's law and its modifications for a conducting frame, the Hashin-Shtrikman (HS) bounds, and the self-similar and complex refraction-index method (CRIM) models. In the elastic case, the stress-strain relations are mainly based on the time-average equation, the HS bounds, and the Gassmann equation. Also, expressions for dry rocks and for anisotropic media, using Backus averaging, are analyzed. The relations are applied to a shale saturated with brine (overburden) and to a sandstone saturated with oil (reservoir). Tests with sections of a North Sea well log show that the best fit is given by the relation between the Gassmann velocity and the CRIM, self-similar, and Archie models for the conductivity.
Miniature liquid-crystal-on-silicon display assembly (1998)

A novel integrated assembly process for miniature liquid-crystal-on-silicon displays using photodefinable benzocyclobutene resin is presented. Spin coating speed defines the cell gap, photolithography defines the cell perimeter and spacers, and thermocompression bonding provides the adhesion. The photodefined adhesive spacers provide thin liquid-crystal cell gap control <2.5 µm with excellent uniformity (±100 nm) for glass-on-glass and glass-on-silicon assemblies. The resin is compatible with common liquid-crystal alignment films and exhibits a bonding shear strength of 22±3.2 MPa?The assembly process flow and characterization of demonstration devices are described.
The impact of parallel GaN HEMTs on efficiency of a 12-to-1 V buck converter (2013)

The impact of parallel GaN HEMTs on efficiency of a non-isolated point of load (POL) converter is investigated. The test results indicate how many parallel GaN HEMTs should be used to achieve maximum efficiency based on load current. Loss calculations and simulations provided initial direction, and ten POL converters were tested-only varying the number of paralleled GaN HEMTs. Each design was tested between 2.5 and 30 A output. Depending on application load and frequency, the optimal combination of GaN HEMTs can be derived from this data. Results indicate that above 19.5 A load, two EPC2015 switches and four EPC2015 synchronous rectifiers (referred to as 2×2015/4×2015) minimizes loss. Below 19.5 A load, a 1×2015/2×2015 HEMT combination minimizes loss. Results presented here should expedite the design process for future engineers seeking greater power supply efficiency with GaN transistors, and it provides novel test data over a large load spectrum, variety of frequencies, and ten combinations of GaN HEMTs in a non-isolated POL converter.
Abstract 289: Sex Hormones Influence Progression of Angiotensin II-Induced Abdominal Aortic Aneurysms in Hypercholesterolemic Mice (2014)

Objectives: Similar to humans, angiotensin II (AngII)-induced abdominal aortic aneurysms (AAA) exhibit marked sexual dimorphism with a greater prevalence in male than female mice. We demonstrated that castration of male mice reduced formation of AngII-induced AAAs, while castration of females had no effect. However, the role of sex hormones (testosterone or estrogen) on the progression of an established AAA is undefined. We tested the hypothesis that sex hormones influence the progression of AngII-induced AAAs. Methods/Results: Male ApoE-/- male mice were infused with AngII (1,000 ng/kg/min) for 28 days to induce AAAs, stratified to sham-operated or castration groups, and subsequently infused with AngII for 56 days. Aortic lumen diameters were decreased significantly in castrated compared to sham controls (1.9 ± 0.1 vs 1.6 ± 0.1 mm, P<0.05). While external AAA diameters were not different between groups, 3D image analysis revealed increased wall/lumen ratios of AAAs from castrated compared to sham controls (9.5 ± 2.0 vs 4.8 ± 0.9 ratio; P<0.05). Increased AAA wall thickness was associated with more pronounced α-actin immunostaining and increased matrix deposition. In contrast, castration had no effect on AngII-induced atherosclerosis. LDLr-/- female mice that received a single dose of testosterone at 1 day of age to promote adult AAA susceptibility were infused with AngII. Females with an established AAA were stratified to sham-operated, castrated, and castrated+estrogen (E 2 , 36 μg/ml) groups for 56 days of AngII infusions. Castration of females significantly increased aortic lumen diameters compared to castrated females administered E 2 (vehicle, 2.2 ±0.2; E 2 , 1.7 ± 0.1 mm, P<0.05). Moreover, E 2 administration significantly decreased external aortic diameters (castrated, 2.6 ± 0.3; castrated+E 2 , 1.7 ± 0.1 mm, P<0.05). Finally, castrated females administered E 2 had significantly decreased atherosclerosis compared to sham controls (38.9 ± 3.6 vs 49.6 ± 2.3 % lesion surface area; P<0.05). Conclusions: These results indicate that testosterone contributes to AAA progression in males whereas E 2 administration lowered AAA progression in female mice.

[Regulation of the RNAse activity of the saliva in healthy subjects and in stomach cancer]. (1989)

Acidic and alkaline RNase activity from healthy humans and gastric cancer patients has been studied. A decrease in daily saliva production and an increase in RNase activity was detected saliva of cancer patients. This suggests the existence of RNase inhibitors in healthy humans. This supposition is further confirmed by comparative analysis of total, joint fractional and reconstituted RNase activity. A considerable increase in acidic RNase inhibitors and disappearance of alkaline RNase inhibitor was observed in cancer patients. The specificity, mechanisms and clinical significance of this phenomena has been discussed.
Detection of Early Abl Kinase Activation after Ionizing Radiation by Using a Peptide Biosensor (2012)

The ubiquitously expressed Abl protein is a non-receptor tyrosine kinase that undergoes nuclear-cytoplasmic shuttling and is involved in many signaling pathways in the cell. Nuclear Abl is activated by DNA damage to regulate DNA repair, cell-cycle checkpoints and apoptosis. Previous studies have established that ataxia telangiectasia mutated (ATM) activates nuclear Abl by phosphorylating serine 465 (S465) in the kinase domain in response to ionizing radiation (IR). Using a peptide biosensor that specifically reports on the Abl kinase activity, we found that an Abl-S465A mutant, which is not capable of being activated by ATM through the canonical site, was still activated rapidly after IR. We established that DNA-dependent protein kinase (DNAPK) is likely to be responsible for a second pathway to activate Abl early on in the response to IR through phosphorylation at a site other than S465. Our findings show that nuclear and cytoplasmic Abl kinase is activated early on (within 5 min) in response to IR by both ATM and DNAPK, and that although one or the other of these kinases is required, either one is sufficient to activate Abl. These results support the concept of early Abl recruitment by both the ATM and the DNAPK pathways to regulate nuclear events triggered by DNA damage and potentially communicate them to proteins in the cytoplasm.
