PRÉSERVATION DE LA MUSIQUE AVEC DISPOSITIF ÉLECTRONIQUE: L’INTÉRÊT DES PROCESSUS DE PRODUCTION SONORE (2014)

L’ouverture des pratiques de production musicale au grand public entraîne une explosion des formats et une obsolescence technologique extrêmement rapide. La mu-sique avec dispositif électronique est fortement dépen-dante des technologies et sa préservation est de plus en plus complexe. Actuellement, la mise à jour régulière de l’œuvre est la méthode la plus efficace pour la préserver et permettre de nouvelles représentations. Ces « portages » nécessitent de modifier l’œuvre en profondeur, ce qui pose un risque de perte d’authenticité: pour la conserver à chaque cycle de transformation, il est nécessaire de dispo-ser des informations déterminant les invariants. L’étude du processus de production est une source unique: des infor-mations comme l’intentionnalité de l’œuvre et la méthode de production y sont transcrites, facilitant grandement la migration. Nos travaux veulent modéliser ces processus de production afin de proposer une représentation de la création des œuvres et offrir un accès aux informations. 1.

Multiaxial Fatigue Crack Initiation in Rubber (2001)

Abstract This paper describes a new model for predicting multiaxial fatigue crack initiation in rubber. The work is motivated by a need to predict crack initiation life in tires, based on strain histories obtained via finite element analysis. The new model avoids the need to explicitly include cracks in the finite element model, and applies when the cracks are small compared to the strain gradient. The model links the far‐field strain state to the energy release rate of an assumed intrinsic flaw. This is accomplished through a new parameter, the cracking energy density. The cracking energy density is the portion of the total elastic strain energy density that is available to be released on a given material plane. The model includes an algorithm to select the material plane which minimizes the life prediction for a given strain history. The consequences of the theory for simple strain histories are presented, as well as predictions for more complicated histories. The theory is compared with published data, and with new results from recent combined axial/torsion fatigue experiments.
Enhancement of molecular weight build up in polyimides using ether solvents (1985)

Two linear polyimides were prepared in various ether and amide solvents. The inherent viscosity was then monitored as a function of time. The polymers made in the ether solvents consistently gave higher inherent viscosities, and thus molecular weights, than the same polymers made in the amide solvents. This molecular weight buildup is attributed to the unique solvation mechanism of the ether solvents which enhances the basicity of the amines via hydrogen bonding.
Software defined apertures for 5G wireless network communications (2015)

Commercialized, low C-SWAP (Cost, Size, Weight and Power), software defined communications apertures will substantially increase network capacity in future 5G wireless networks. We advocate using high gain, electronically steerable antennas for small cell radio access networks, backhaul and millimeter wave applications. The steerable beam functionality can provide elevated data rates, reduced power consumption, allow spectrum reuse and enable dynamic network reconfiguration. Additionally, network operating costs would be reduced and deployment schedules would become more flexible. In this paper we elucidate the advantages of using such an antenna in 5G network topologies. We also discuss some of the effects of high-gain, electronically steerable antennas on standards development.
Photon-number squeezing in an integrated light emitter/detector system (2003)

Generation of nonclassical lights, such as photon-number squeezed states and quadrature-phase squeezed state, is required to realize optical communications and accurate measurements at sub-shot-noise levels. Among a variety of schemes, the direct generation of sub-Poissonian photon fluxes from semiconductor light emitters has been attracting much attention because of the simplicity of experimental arrangement, the low energy consumption, the possibility of a large degree of noise suppression, and the compatibility with modern communication system. In this presentation, we demonstrate the experimental results of generation of sub-Poissonian photon fluxes in an integrated light-emitter/detector system. It is shown that the pump-noise-suppression owing to the macroscopic Coulomb blockade effect can work well even when a superlattice alloylike material is used.
Approaching the limits of carrier-envelope phase stability in a millijoule-class amplifier (2014)

The demand for ever shorter light pulses presents a challenge to the detection and stabilization of the carrier-envelope phase (CEP) in amplifier systems. Here we present a combination of single-shot detection and a fast actuator that is capable of measuring and correcting the CEP in every single shot emitted by a millijoule-scale, multi-kHz femtosecond laser amplifier. The residual CEP noise within 50 s amounts to 98 mrad rms in-loop (fast detection, 5·10⁵ shots) and 140 mrad out-of-loop (slow detection, 6250 shots), approaching the noise floor of the f-to-2f measurement. Both values represent a twofold improvement of the CEP stability over previously published results in comparable systems.
Mechanisms of osteoarthritis in the knee: MR imaging appearance (2014)

Osteoarthritis has grown to become a widely prevalent disease that has major implications in both individual and public health. Although originally considered to be a degenerative disease driven by “wear and tear” of the articular cartilage, recent evidence has led to a consensus that osteoarthritis pathophysiology should be perceived in the context of the entire joint and multiple tissues. MRI is becoming an increasingly more important modality for imaging osteoarthritis, due to its excellent soft tissue contrast and ability to acquire morphological and biochemical data. This review will describe the pathophysiology of osteoarthritis as it is associated with various tissue types, highlight several promising MR imaging techniques for osteoarthritis and illustrate the expected appearance of osteoarthritis with each technique.

Adaptive CAD-model building algorithm for general planar microwave structures (1999)

A new adaptive technique is presented for building multidimensional parameterized analytical models for general planar microwave structures with a predefined accuracy and based on full-wave electromagnetic (EM) simulations. The models can be incorporated in a circuit simulator and the time required to calculate the circuit representation of a practical network is reduced by several orders of magnitude compared to full EM simulations. Furthermore, the accuracy of the results is significantly better compared to the circuit models used in state-of-the-art computer-aided design tools.
Data from Inhibitor-Sensitive FGFR2 and FGFR3 Mutations in Lung Squamous Cell Carcinoma (2023)

&lt;div&gt;Abstract&lt;p&gt;A comprehensive description of genomic alterations in lung squamous cell carcinoma (lung SCC) has recently been reported, enabling the identification of genomic events that contribute to the oncogenesis of this disease. In lung SCC, one of the most frequently altered receptor tyrosine kinase families is the fibroblast growth factor receptor (FGFR) family, with amplification or mutation observed in all four family members. Here, we describe the oncogenic nature of mutations observed in &lt;i&gt;FGFR2&lt;/i&gt; and &lt;i&gt;FGFR3&lt;/i&gt;, each of which are observed in 3% of samples, for a mutation rate of 6% across both genes. Using cell culture and xenograft models, we show that several of these mutations drive cellular transformation. Transformation can be reversed by small-molecule FGFR inhibitors currently being developed for clinical use. We also show that mutations in the extracellular domains of &lt;i&gt;FGFR2&lt;/i&gt; lead to constitutive FGFR dimerization. In addition, we report a patient with an &lt;i&gt;FGFR2&lt;/i&gt;-mutated oral SCC who responded to the multitargeted tyrosine kinase inhibitor pazopanib. These findings provide new insights into driving oncogenic events in a subset of lung squamous cancers, and recommend future clinical studies with FGFR inhibitors in patients with lung and head and neck SCC. &lt;i&gt;Cancer Res; 73(16); 5195–205. ©2013 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
Influence of secondary structure (helical conformation) on stereoselectivity in peptide couplings (1987)

The stereoselectivity in the peptide bond formation was investigated and it was demonstrated that secondary structure–secondary structure interaction is significant in affecting the stereochemical course of peptide bond formation.
Diversity Synthesis via C−H Bond Functionalization:  Concept-Guided Development of New C-Arylation Methods for Imidazoles (2003)

Herein, we have formulated the concept of systematic derivatization of a structural motif via C-H bond functionalization. This concept may not only serve as a blueprint for new strategies in diversity synthesis but also provide systematic guidance for the identification of unsolved and important synthetic challenges. To illustrate this point, 2-phenylimidazole was selected as the core motif for this study, a choice inspired by numerous azole-based synthetics, including pharmaceuticals (compound SB 202190), and also fluorescent and chemiluminescent probes. We were able to show that systematic and comprehensive arylation of the 2-phenylimidazole core was feasible, and in the context of this study new arylation methods were developed. The direct 4-arylation of free 2-phenylimidazole was achieved with iodoarenes as the aryl donors in the presence of palladium catalyst (Pd/Ph(3)P) and magnesium oxide as the base. A complete switch from C-4 to C-2' arylation was accomplished using a ruthenium catalyst [CpRu(Ph(3)P)(2)Cl] and Cs(2)CO(3). The corresponding transformations for (N,2)-diphenylimidazole (C-5 and C-2' arylation) were accomplished via the palladium-based method [Pd(OAc)(2)/Ph(3)P/Cs(2)CO(3)] and a rhodium-catalyzed procedure [Rh(acac)(CO)(2)/Cs(2)CO(3)], respectively. All of the arylation methods described herein demonstrated broad synthetic scope, high efficiency, and exclusive selectivity. Furthermore, these new methods proved to be orthogonal to one another and applicable to sequential arylation schemes. With these methods in hand, arrays of arylated imidazoles may now be accessed in a direct manner from 2-phenylimidazole. This strategy stands in sharp contrast to a traditional approach, wherein a distinct and multistep synthesis would be required for each analogue.
Epigenetic regulation of human α 1d ‐adrenergic receptor gene expression: a role for DNA methylation in Spl‐dependent regulation (2007)

A growing body of evidence implicates alpha1-adrenergic receptors (alpha1ARs) as potent regulators of growth pathways. The three alpha1AR subtypes (alpha1aAR, alpha1bAR, alpha1dAR) display highly restricted tissue expression that undergoes subtype switching with many pathological stimuli, the mechanistic basis of which remains unknown. To gain insight into transcriptional pathways governing cell-specific regulation of the human alpha1dAR subtype, we cloned and characterized the alpha1dAR promoter region in two human cellular models that display disparate levels of endogenous alpha1dAR expression (SK-N-MC and DU145). Results reveal that alpha1dAR basal expression is regulated by Sp1-dependent binding of two promoter-proximal GC boxes, the mutation of which attenuates alpha1dAR promoter activity 10-fold. Mechanistically, chromatin immunoprecipitation data demonstrate that Sp1 binding correlates with expression of the endogenous gene in vivo, correlating highly with alpha1dAR promoter methylation-dependent silencing of both episomally expressed reporter constructs and the endogenous gene. Further, analysis of methylation status of proximal GC boxes using sodium bisulfite sequencing reveals differential methylation of proximal GC boxes in the two cell lines examined. Together, the data support a mechanism of methylation-dependent disruption of Sp1 binding in a cell-specific manner resulting in repression of basal alpha1dAR expression.

OXYGEN-STABLE HEMOLYSINS OF GROUP A STREPTOCOCCI (1963)

The production of oxygen-stable hemolysin in growing and resting Group A streptococci has been induced by RNA, by detergents, and by mammalian blood serum proteins, in the presence of glucose, Mg(++), and cysteine. Of the serum proteins, albumin and alpha lipoprotein could act as inducers. In the case of both these serum proteins treatment with trypsin did not affect the capacity to induce hemolysin production, but removal of the bound lipids by alcohol-ether or chloroform-methanol destroyed this property. In comparisons of the conditions of production and of activity between the hemolysin produced by RNA on one hand and albumin and detergents on the other, some data indicated similarities among the hemolysins, and others, differences. The similarities included similar degrees of temperature dependence for production and equal degrees of inhibition by serum beta lipoprotein. Differences found among these hemolysins included differences between, the rate of production of the RNA hemolysin from that of albumin or detergent hemolysin by both resting and growing streptococci, and the failure of utilization of glucosamine as an energy source for the production of albumin hemolysin, in contrast with that of RNA hemolysin. The fact that the data have in some cases indicated similarities and in other cases differences among the hemolysins raises the question of whether these are different molecular species, or a single hemolysin synthesized by the streptococci via different pathways of metabolism, or complexes of a single hemolytic moiety with various molecular carriers.
Comparison of microstructure, second phases and texture formation during melt processing of Bi-2212 mono- and multifilament wires (2016)

Based on simultaneous in situ high energy synchrotron micro-tomography and x-ray diffraction (XRD) measurements we compare the microstructural changes and the formation of second phases and texture during the processing of Bi-2212 round wires with 15 μm filament diameter (multifilament) and 650 μm filament diameter (monofilament) fabricated using identical Bi-2212 precursor. The monofilament tomograms show in unprecedented detail how the distributed porosity agglomerates well before Bi-2212 melting decomposition to form lenticular voids that completely interrupt the filament connectivity along the wire axis. When the Bi-2212 phase completely melts connectivity in the axial wire direction is established via the changes in the void morphology from the lenticular voids to bubbles that remain when Bi-2212 crystallises out of the melt. By measuring the attenuation of the monochromatic x-ray beam, the associated Bi-2212 mass density changes have been monitored during the entire heat cycle. The XRD results reveal that the wire architecture can have a strong influence on the phase evolution during the melt processing heat treatment affecting the reversibility of Bi-2212 melting decomposition reaction. A strong Bi-2212 texturing is only achieved in the multifilament wire, while in the monofilament wire Bi-2212 crystallites grow with nearly random orientation.
Active ultrasonic cross-correlation flowmeters for mixed-phase pipe flows. [Solid/liquid and solid/gas flows] (1984)

This paper describes two ultrasonic flowmeters which employ the active cross-correlation technique and uses a simple clamp-on transducer arrangement. The flowmeter for solid/liquid flows was tested over a wide range of coal concentration in water and oil. The measured velocity based on the peak position of the cross-correlation function is consistently higher by about 15% than the average velocity measured by flow diversion. The origin of the difference results mainly from the flow velocity profiles and the transit-time probability distribution. The flowmeter that can measure particle velocity in a solid/gas flow requires acoustic decoupling arrangement between two sensing stations. The measured velocity is mainly associated with the particles near the wall. Performance of both flowmeters is presented.
Detection and mitigation of jamming attacks in massive MIMO systems using random matrix theory (2016)

Consider the uplink of a single-cell multiuser MIMO system with a very large number of antennas, M, at the base station (BS) and K single-antenna users. A jamming device equipped with K <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">J</sup> antennas transmitting signals attempts to degrade the transmission between the users and the BS. In this paper, we propose a detection algorithm of the jamming attack as well as a method for its rejection. The proposed results are based on the application of results from random matrix theory. We assume that K and K <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">J</sup> are fixed as M converges to infinity while the coherence interval τ is assumed to be of the same order of magnitude as M.
Inter-laboratory Evaluation Studies for Establishment of Notified ELISA Methods for Allergic Substances (Buckwheat) (2004)

Inter-laboratory evaluation studies were conducted for the ELISA methods for allergic substances (buckwheat). Extracts of snack, bun and udon spiked with buckwheat standard protein at a level of 5-20 ng/mL as sample solutions were analyzed in replicate at 10 laboratories. Coefficients of variation (CVs) of the ELISA methods using a Buckwheat Protein ELISA Kit (Buckwheat kit) and a FASTKIT Buckwheat ELISA kit (Buckwheat ELISA kit) were mostly below 10%. Mean recoveries of the buckwheat standard protein from the food extracts were over 40% in the two ELISA methods. Repeatability relative standard deviations of buckwheat standard protein in three food extracts were in the ranges of 6.8-78.5% and 5.0-33.9% for the Buckwheat kit and the Buckwheat ELISA kit, respectively. Reproducibility relative standard deviations of buckwheat standard protein in three food extracts were 11.9-69.5% and 16.5-34.1% for the Buckwheat kit and the Buckwheat ELISA kit, respectively. The detection limits of both ELISA methods were 1 ng/mL in sample solutions. These results suggest that the notified ELISA methods are reliable and reproducible for the inspection of buckwheat protein levels in extracts of snack, bun and udon.
An Improved Approach for the Synthesis of Multiplication-Free Highly-Selective FIR Half-Band Decimators and Interpolators (Invited Paper) (2009)

A substantial improvement is provided in compar- ison with the systematic approach recently presented by the authors of this paper to generate multiplication-free decimators and interpolators. As the earlier one, the proposed approach is founded, first, on expressing the transfer function of a linear- phase finite-impulse response (FIR) half-band filters as a sum of the terms (1/2)zM and G(z 2 ), where the odd integer M is the order of G(z), and, then, on constructing G(z) as a special tapped cascaded interconnection of identical subfilters. The essential improvement is in a quite optimized way of gener- ating multiplication-free tap coefficients such that the resulting passband alteration of the subfilter required by meeting the overall filter criterion becomes significantly larger than in the earlier approach, where this variation is already huge against what is required by the overall filter. This increased passband alteration results in a considerably lowered subfilter order, which, in turn, even further eases finding multiplication-free representations for its coefficient values and decreases the overall filter order. Examples are included illustrating the superiority of the resulting multiplication-free filters compared with those achievable by the earlier approach and their direct-form FIR equivalents. Index Terms—Multiplication-free filters, optimization, half- band filters, decimators and interpolators.
