Elaboration et caractérisation d'alliages magnétiques Fe-Si et Fe-Si-Al enrichis par dépôt chimique à partir d'une phase gazeuse pour des applications à basses et moyennes fréquences (1994)

Le but de ce travail consiste a elaborer des materiaux magnetiques doux fer-silicium-aluminium et fer-silicium par depot chimique en phase gazeuse et de comparer leurs proprietes magnetiques a celles d'alliages industriels. Les interactions surface metallique-phase gazeuse halogenee conduisent des les premiers instants a une germination epitaxique des composes fer-silicium-aluminium puis a une solution solide sous-jacente apres diffusion. Les teneurs en silicium et/ou en aluminium ainsi que les gradients de concentration obtenus dependent des conditions de depot (procedes statique et dynamique, nature et composition des gaz, temperature, duree de traitement et nature des substrats). Des etudes cinetiques ont ete realisees et leurs interpretations sont basees sur les observations effectuees par microscopie optique et electronique et radiocristallographie. Les proprietes magnetiques et magnetomecaniques de ces alliages sont donnees. L'enrichissement en silicium et/ou en aluminium permet de reduire considerablement les pertes magnetiques, les constantes de magnetostriction et les effets magnetomecaniques (capacite d'amortissement de vibrations, emission magnetoacoustique)
Smart instruments: Wireless technology invades the operating room (2012)

Wireless medical instruments have revolutionized the medical industry for numerous applications including diagnostics, surgical, in vivo, remote patient monitoring, and indoor positioning. The current research trend is to integrate even more biosensors, electronics, and wireless technologies into low power, small form factor systems that can be worn or directly implanted into patients. Diagnostic monitoring systems can provide non-invasive in vivo tracking and real-time diagnosing capabilities. Smart surgical tools provide wireless sensing and tracking for computer assisted surgery and seamless use intraoperatively. Wireless systems will continue to play an integral role in the future of healthcare technology and hospital infrastructure including various types of wireless sensors networks (body area networks, personal area networks) and devices being deployed inside the hospital and operating room and extended into remote locations including the patient's home and workplace.
Human (α2→6) and Avian (α2→3) Sialylated Receptors of Influenza A Virus Show Distinct Conformations and Dynamics in Solution (2013)

Differential interactions between influenza A virus protein hemagglutinin (HA) and α2→3 (avian) or α2→6 (human) sialylated glycan receptors play an important role in governing host specificity and adaptation of the virus. Previous analysis of HA-glycan interactions with trisaccharides showed that, in addition to the terminal sialic acid linkage, the conformation and topology of the glycans, while they are bound to HA, are key factors in regulating these interactions. Here, the solution conformation and dynamics of two representative avian and human glycan pentasaccharide receptors [LSTa, Neu5Ac-α(2→3)-Gal-β(1→3)-GlcNAc-β(1→3)-Gal-β(1→4)-Glc; LSTc, (Neu5Ac-α(2→6)-Gal-β(1→4)-GlcNAc-β(1→3)-Gal-β(1→4)-Glc] have been explored using nuclear magnetic resonance and molecular dynamics simulation. Analyses demonstrate that, in solution, human and avian receptors sample distinct conformations, topologies, and dynamics. These unique features of avian and human receptors in solution could represent distinct molecular characteristics for recognition by HA, thereby providing the HA-glycan interaction specificity in influenza.
Reverse Shoulder Arthroplasty for the Treatment of Nonunions of the Surgical Neck of the Proximal Part of the Humerus (Type-3 Fracture Sequelae) (2014)

Nonunions of the proximal part of the humerus can be treated with reverse shoulder arthroplasty. Although clinical outcomes improved significantly, we found an unacceptably high rate of dislocations associated with intraoperative resection of the tuberosities. The tuberosities and the attached rotator cuff should be preserved if possible to reduce the risk of dislocation after reverse total shoulder arthroplasty.

Novel Low-Cost Selective Pre-Concentrators Based on Metal Organic Frameworks (2016)

Metal organic frameworks (MOFs) are used as selective preconcentrator-materials in order to improve the overall sensor-system sensitivity. MOFs exhibit interior surface areas of above 1000 m2/g and possess chemically uniform pore structures that render them a perfect sorbent for highly specific interaction with guest molecules. They are evaluated using inverse gas chromatography (iGC) and deposited on microheaters in order to perform cyclic preconcentration measurements on an existing sensor platform.
Non-infectious phosphate renal calculi: Fine structure, chemical and phase composition (2011)

Phosphate renal calculi with the low Ca/P molar ratio predominantly consist of amorphous calcium phosphate whereas those with a high Ca/P molar ratio are composed of poorly crystalline hydroxyapatite which can be partially carbonated. Magnesium may be an inhibitor of HAP formation from urine. Abundant organic matter incorporated into the calculus volume indicates its decisive role at stone formation. Variable point composition of stones implies widely varying conditions during their development.
Blue emission from Tm-doped GaN electroluminescent devices (1999)

Blue emission has been obtained at room temperature from Tm-doped GaN electroluminescent devices. The GaN was grown by molecular beam epitaxy on Si(111) substrates using solid sources (for Ga and Tm) and a plasma source for N2. Indium–tin–oxide was deposited on the GaN layer and patterned to provide both the bias (small area) and ground (large area) transparent electrodes. Strong blue light emission under the bias electrode was observable with the naked eye at room temperature. The visible emission spectrum consists of a main contribution in the blue region at 477 nm corresponding to the Tm transition from the G41 to the H63 ground state. A strong near-infrared peak was also observed at 802 nm. The relative blue emission efficiency was found to increase linearly with bias voltage and current beyond certain turn-on levels.
Idle Mode Measurements to Enable Fast Small Cell Access without Compromising Energy Efficiency (2018)

Offloading traffic to small cells is one of the key enablers in achieving high peak data rates in a heterogeneous cellular network deployment. In this paper, we introduce and evaluate a solution to significantly speed up the small cell access in LTE or NR based on UE performing additional small cell measurements in idle state. These additional measurements naturally have a cost as additional energy consumption in the UE, but enable much faster small cell setup when there is data. The conventional wisdom has been to minimize the amount of measurements in the idle state to keep the UE battery life as long as possible. However, our results show that by leveraging the substantially better energy efficiency of data transmission in a small cell, a net positive effect can be achieved in a typical scenario. The performance gains are compelling: We observe user perceived throughput up to 5-10 times higher, while still maintaining lower average UE energy consumption.
Pharmacological characterization of A-131701, a novel ?1-adrenoceptor antagonist selective for ?1A- and ?1D-compared to ?1B-adrenoceptors (1998)

New compounds selective for α1A-adrenoceptors in the prostate may offer enhanced efficacy for benign prostatic hyperplasia (BPH), with fewer side effects than current treatment. A-131701 (3-[2-((3aR,9bR)-cis-6-methoxy-2,3,3a,4,5,9b,hexahydro-[1H]-benz[e]isoindol-2-yl)ethyl]pyrido[3′,4′:4,5]thieno [3,2-d]pyrimidine-2,4(1H,3H)-dione), from a novel class of benz[e]isolindole pyridothienopyrimidines and pyridothienopyrazines, is selective for α1a- and α1d-adrenoceptors in radioligand binding studies (0.22 nM at α1a-, 0.97 nM at α1d-) compared to α1b-sites (2.5 nM) and in isolated tissue bioassays (pA2 values of 8.9–9.0 for α1A-receptors in rat vas deferens or canine prostate strips, 9.1 at α1D-sites (rat aorta)), compared to 7.9 at α1B-sites (rat spleen). A-131701 also potently blocked radioligand binding to α1-adrenoceptors in canine and human prostatic membranes, but was considerably weaker at α2-adrenoceptors. In isoflurane-anesthetized dogs, A-131701 antagonized epinephrine-induced increases in intraurethral pressure (IUP) with a pseudo-pA2 value of 8.17. In spontaneously hypertensive rats, A-131701 caused transient decreases in mean arterial blood pressure (MABP) and transient tachycardia. The area under the curve (AUC0→60 min) for the hypotensive response was dose-related, with a log index value for A-131701 of 5.33, suggesting a selectivity of >600-fold comparing IUP to MABP effects. In pentobarbital-anesthetized dogs, A-131701 was more potent in blocking phenylephrine (PHE)-induced increases in IUP (pseudo-pA2 = 8.0) compared to concurrently measured MABP (pseudo-pA2 = 7.2), or sixfold selective. Doses greater than 1,000 nmol/kg i.v. of A-131701 were required to lower blood pressure by 10 mm Hg in these dogs (pED10 =. 5.57), indicating a uroselectivity ratio of >250, superior to doxazosin, terazosin, or tamsulosin. Thus, A-131701 is selective for α1A- and α1D- vs. α1B-adrenoceptors in vitro, and prostatic function vs. blood pressure effects in vivo, which may provide therapeutic advantages in the treatment of BPH.

A New Solids Technology Train: Can 70% Volatile Solids Reduction and Class A Biosolids be Achieved from Digestion? (2009)

A New Solids Technology Train: Can 70% Volatile Solids Reduction and Class A Biosolids be Achieved from Digestion?There has been an increase in interest amongst utilities to develop solids technology concept trains that result in solids volume reduction for land application. For example, the Water Environment Research Foundation has recently initiation the OWSO “optimization” program in part to develop concepts that reduce sludge volumes for beneficial reuse or disposal.

Perspectives on poly(dopamine) (2013)

Poly(dopamine) has emerged in recent years as a readily accessible synthetic analogue of the naturally occurring melanins. However, the polymer's structure has proved difficult to unambiguously elucidate and a variety of models have been proposed. Despite these challenges, poly(dopamine) has found extraordinary utility in a range of applications including surface coatings, biotechnology and biomedicine, and water purification membranes. Most of these applications take advantage of the robust polymer films that deposit onto a wide range of surfaces, as well as its inertness to harsh chemical environments. In view of the expansion of interest in poly(dopamine), we provide perspective on this material, focusing on its history, chemical relationship to melanins, recent applications, and potential areas for future study.

1628 Numerical Analysis of Unsteady Flow Phenomena in an Axial Flow Compressor Rotor at Near Stall Condition (2007)

The tip clearance of rotor blades is one of the important factors to be more investigated, because the rotating stall inception originates at a tip leakage flow region in most of axial flow compressors. However, the effect of the tip clearance on unsteady flow field at near-stall condition has not been investigated in detail. In the present work, the unsteady flow phenomena in a low-speed axial flow compressor stage with the large and small tip clearances at near-stall condition have been investigated numerically by URANS (Unsteady Reynolds-averaged Navier-Stokes) simulations. The results show the clear difference caused by the effect of the tip clearance on the flow field at near-stall condition. Namely, the occurrence of separation at the blade suction surface induced instability for small tip clearance, while the occurrence of tip leakage vortex breakdown induced instability for large tip clearance.
Chapter on Distributed Computing (1989)

Abstract : Rigorous analysis starts with a precise model of a distributed system; the most popular models, differing in how they represent interprocess communication, are message passing, shared variables, and synchronous communication. The properties satisfied by an algorithm must be precisely stated and carefully proved; the most successful approach is based on assertional reasoning. Algorithms for solving particular problems in a distributed system can then be designed and analyzed. Typical of the problems that have been addressed are: concurrently accessing shared data, achieving consensus, analyzing network topology, obtaining consistent global information, and controlling database transactions.
L'animal de vérité (2006)

Le philosophe Michel Foucault definissait l'homme comme un «animal de verite». Defait, Homo sapiens semble etre le seul etre pouvant temoigner d'une volonte de connaitre. Mais de quoi s'agit-il? Est-ce possible? La volonte de puissance ne se cache-t-elle pas sous la revendication d'un libre acces au savoir? Cela fait 25 siecles - au moins - qu'on se pose ces questions, qui demeurent neanmoins d'une brulante actualite en ces temps ou co-existent une science triomphante, qui voudrait que rien ne lui echappe; et un retour a un fondamentalisme integriste qui en conteste parfois la legitimite meme.
An aluminum‐germanium eutectic structure for silicon wafer bonding technology (2005)

An aluminum-germanium eutectic bonding technology has been used to uniformly bond two silicon wafers for MEMS packaging at temperatures as low as 450 °C, well below the aluminum-silicon eutectic temperature (577 °C). A device silicon wafer has been put in contact with a cap wafer where an aluminum film covered by a germanium film has been thermally evaporated. The annealing has been performed in a vacuum furnace under uniaxial pressure variable from 1.8 up to 30 kbar. The samples have been analyzed with various analytical techniques. 4He+ MeV Rutherford Backscattering Spectrometry (RBS) has been used to measure the thicknesses of the deposited films and to follow the aluminum-germanium intermixing, Scanning Acoustic Microscope (SAM) to control the uniformity of the bonding, Scanning Electron Microscope (SEM) associated with electron induced X-ray fluorescence to analyze composition, morphology and elements distribution in the film between the two bonded wafers. The temperatures for the annealing were selected above and below the Ge-Al the eutectic temperature. At temperatures below the eutectic no-bonding has been obtained for any applied pressure. Above the eutectic bonding occurs. The formation of a liquid film is mandatory to obtain a reproducible and robust bonding. The pressure is necessary to improve the contacts between the two wafers; its role in the metallurgy of the bonding needs to be explored. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
Commentary: The Operatic Tragedy of Central Europe (2006)

The operas of Leos Janacek-such as Jenufa and Katya Kabanova-illustrate the nature of operatic modernism in relation to history and folklore in the context of the Habsburg monarchy and postwar Central Europe. In the performance history of the operas, moving from Janacek's city of Brno, Moravia, to such cosmopolitan capitals as Prague, Vienna, Berlin, and even New York, the case of Janacek also suggests the complex relationship between provincial, national, and transnational elements in the operatic modernism of Central Europe.
Embedded fiber optic Bragg grating (FBG) detonation velocity sensor (2009)

In order to fully calibrate hydrocodes and dynamic chemistry burn models, initiation models and detonation models of high explosives, the ability to continuously measure the detonation velocity within an explosive is required. Progress on an embedded velocity diagnostic using a 125 micron diameter optical fiber containing a chirped fiber Bragg grating is reported. As the chirped fiber Bragg grating is consumed by the moving detonation wave, the physical length of the unconsumed Bragg grating is monitored with a fast InGaAs photodiode. Experimental details of the associated equipment and data in the form of continuous detonation velocity records within PBX-9502 are presented. This small diameter fiber sensor has the potential to measure internal detonation velocities on the order of 10 mm/&mu;sec along path lengths tens of millimeters long.
Kinetics of water transfer and stress relaxation in cartilage heated with 1.56-μm fiber laser (2000)

In this work we have used for the first time 1.56 micrometer fiber laser to study mechanisms of IR laser induced stress relaxation in cartilage. We have applied several in-situ monitoring techniques: local temperature measurements (IR radiometry and thermocouple), IR-light absorption, direct stress measurements, micro-balancing, visible light scattering and optical coherent tomography. We have measured temporal behavior of 1.56 micrometer laser light transmission through the cartilage sample at different intensities with synchronous temperature and stress monitoring. The observed bleaching effect (self-induced transparency) is caused by water release from irradiating zone, water evaporation from the cartilage surface and, also, by temperature shift and decrease of intensity of water absorption bands.
Pulverization Strategy for Graphite-CoOx Composite Cathode of Lithium-Air Batteries (2015)

The lithium-air battery has been attracted around the world owing to very high energy density, which could well satisfy the increased energy requirement from electronic devices, especially the electric vehicle. 1-3 However, despite large R&amp;D efforts devoted to its implementation, several issues have so far limited the performance of the lithium oxygen battery because of few discharge-charge cycles, large polarization and low rate capability. 4, 5 Some researchers used many materials for cathode in lithium air batteries because inherent activation effect and morphology of each material had an effect to decrease polarization and increase capacity. Although carbon has been talked making by-product like Li 2 CO 3 , it is the mostly used material because of the advantage in the way that amount and cost. Some paper told that not only carbon but also electrolyte co-makes this side reaction problem in lithium oxygen battery system. In this study, a new physical pulverization strategy has been developed to prepare a highly active composite of CoO x and crushed graphite (CG) for the cathode in lithium–air batteries. The effect of CoO x loading on the charge potential in the oxygen evolution reaction was investigated in coin cell tests. The CoO x (38.9 wt%)/CG composite showed a low charge potential of 3.92 V with a delivered capacity of 2 mAh/cm 2 under a current density of 0.2 mA/cm 2 . The charge potential was 4.10 and 4.15 V at a capacity of 5 and 10 mAh/cm 2 , respectively, with a current density of 0.5 mA/cm 2 . The stability of the electrolyte and discharge product on the gas-diffusion layer after the cycling were preliminarily characterized by 1H nuclear magnetic resonance spectroscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The high activity of the composite was further analyzed by electrochemical impedance spectroscopy, cyclic voltammetry, and potential-step chronoamperometry. The results indicate that our near-dry milling method is an effective and green approach to preparing a nanocomposite cathode with high surface area and porosity, while using less solvent. Its relative simplicity compared with the traditional solution method could facilitate its widespread application in catalysis, energy storage, and materials science. References [1] K.M.

Stable Containment of Radionuclides on the Nanoscale by Cut Single-Wall Carbon Nanotubes (2005)

The physisorption of radiolabeled (125)I(-) ions from aqueous solution and the Brunauer-Emmett-Teller (BET) surface areas of various carbonaceous materials [HiPco single-wall carbon nanotubes (SWNTs), F-SWNTs, cut SWNTs, charcoal, graphite, F-graphite and C(60)] have been measured and compared. By far, cut SWNTs (mainly 20-50 nm lengths) displayed the largest surface area of the materials (1180 m(2).g(-1)), being approximately double that of uncut SWNT and charcoal. At low concentrations of (125)I(-), nearly all of the (125)I(-) was adsorbed from aqueous solution within 1 min at room temperature by the cut SWNTs, uncut SWNTs, and charcoal; the other materials showed much less adsorption under the same conditions. Once adsorbed, the (125)I(-) wash-off rate by pure water was highly variable but was especially slow for cut SWNTs (t(1/2) approximately 2720 h) compared to the other materials; wash-off of (125)I(-) by an aqueous H(2)O(2) solution was even slower (t(1/2) approximately 14 300 h). Taken together, these data demonstrate the greatly increased surface area and dramatically enhanced retention properties of cut SWNTs over uncut SWNTs.
