Simulation of interference effects from UWB sources to a digital narrowband transmission system (2006)

This paper reports on the study of the interference effects from 4 types of ultra wideband (UWB) sources on a QPSK transmission system by simulation. The culprit UWB sources were: multi-band orthogonal frequency-division multiple-access (MB-OFDM), direct-sequence code division multiple access (DS-CDMA), DS spread spectrum UWB (DS-SS UWB), and additive white Gaussian noise (AWGN). The MB-OFDM and DS-CDMA were modeled on the proposal specifications in the IEEE.802.15.3a to standardize high-speed wireless personal area networks. Average bit error rate (BER) degradation of the victim system was evaluated under in-band interference from the UWB signal. A proposed modified equivalent baseband system was employed in the simulation which would reduce the simulation costs. Interference effects introduced due to different parameters of the culprit UWB signals and changing bandwidth of the victim receiver were examined

Combined Spectroelectrochemical and Theoretical Study of a Vinylene-Bridged Sexithiophene Cooligomer:  Analysis of the π-Electron Delocalization and of the Electronic Defects Generated upon Doping (2002)

The electronic and the Fourier transform Raman (FT-Raman) spectra of a novel well−barrier−well vinylene-bridged sexithiophene in neutral and in doped states have been recorded. The samples were oxidized chemically, with trifluoroacetic acid or ferric chloride, and electrochemically in dichloromethane solutions. The evolution of the Raman spectral pattern upon oxidation at different anodic potentials has been analyzed for a thin solid film of the material. Experimental observations are explained by the initial generation of a radical cation species followed by the generation of a dication species. A comprehensive assignment of the electronic and Raman spectroscopic features observed in both neutral and oxidized states has been performed on the basis of density functional theory (DFT) calculations. Time-dependent DFT calculations have been performed to calculate the electronic excitation energies. The experimental data and theoretical results give a clear picture of the structure and electronic properties of the charge defects created on this vinylene-bridged sexithiophene.

Crystalline ${\mathrm{As}}_{2}$${\mathrm{S}}_{3}$ (orpiment) is a layer-structure semiconductor whose optical properties, under ordinary conditions, are determined by its diperiodic layer symmetry. We have investigated the effect of hydrostatic pressure on the optical-absorption edge and the Raman scattering spectrum of orpiment. With increasing pressure the optical band gap red-shifts rapidly, decreasing from 2.7 eV at $P=0 \mathrm{to} 1.6$ eV at 100 kbar. The initial slope, $\frac{d{E}_{G}}{\mathrm{dP}}$ at $P=0$, is -(14\ifmmode\pm\else\textpm\fi{}3) meV/kbar, and the closing of the gap is interpreted in terms of pressure-induced enhancement of the interlayer-interaction broadening of intralayer bands. At high pressure, dimensionality effects (2D\ensuremath{\rightarrow}3D) are clearly discerned in the vibrational Raman spectrum. An intralayer quadruplet at 355 ${\mathrm{cm}}^{\ensuremath{-}1}$, near degenerate at zero pressure, disperses at high pressure as the dominance of the diperiodic (isolated layer) symmetry is broken and the admixture repulsion of modes of like crystal symmetry forces them apart. A similar effect occurs at 25 kbar in the forbidden-crossover repulsion of a pair of modes at 145 ${\mathrm{cm}}^{\ensuremath{-}1}$. Also, the rigid-layer modes roughly double in frequency by 100 kbar, corresponding to a quadrupling of the layer-layer coupling. Finally, the pressure data have been used to separate the phonon-occupation-driven (explicit) and the volume-driven (implicit) contribution to the temperature dependence of the band gap and the Raman-active phonon frequencies. We find that ${E}_{G}$ is controlled by the explicit electron-phonon contribution to $\frac{d{E}_{G}}{\mathrm{dT}}$. For the phonons, $\frac{d\ensuremath{\nu}}{\mathrm{dT}}$ of the low-frequency interlayer-interaction modes is dominated by the volume-driven term, while the explicit phonon-phonon effect dominates $\frac{d\ensuremath{\nu}}{\mathrm{dT}}$ for the intralayer modes.
Polystyrene-graft-poly(ethylene oxide) copolymers prepared by macromonomer technique in dispersion. I. Liquid chromatographic separation of product mixtures (2000)

Products of the radical dispersion copolymerization of methacryloyl-terminated poly(ethylene oxide) (PEO) macromonomer and styrene were separated and characterized by size exclusion chromatography (SEC), full adsorption-desorption (FAD)/SEC coupling and eluent gradient liquid adsorption chromatography (LAC). In dimethylformamide, which is a good solvent for PEO side chains but a poor solvent for polystyrene (PS), amphiphilic PS-graft-PEO copolymers formed aggregates, which were very stable at room temperature even upon substantial dilution. The aggregates disappeared at high temperature or in tetrahydrofuran (THF), which is a good solvent for both homopolymers and for PS-graft-PEO. FAD/SEC procedure allowed separation of homo-PS from graft-copolymer and determination of both its amount and molar mass. Effective molar mass of graft-copolymer was estimated directly from the SEC calibration curve determined with PS standards. Presence of larger amount of the homo-PS in the final graft-copolymer products was also confirmed with LAC measurements. The results indicate that there are at least two or maybe three polymerization loci; namely the continuous phase, the particle surface layer and the particle core. The graft copolymers are produced mainly in the continuous phase while PS or copolymer rich in styrene units is formed mostly in the core of monomer-swollen particles. © 2000 John Wiley & Sons, Inc.

Haem oxygenase‐1 polymorphisms can affect HCV replication and treatment responses with different efficacy in humanized mice (2016)

Although the protective function of HO-1 could be elicited in vivo with both host polymorphisms, the strength of HO-1 induction and suppression of HCV occurred in a polymorphism-dependent manner, indicating that host-genetic determinants may affect disease progression and infection outcome.
Deriving a simulation input generator and a coverage metric from a formal specification (2002)

This paper presents novel uses of functional interface specifications for verifying RTL designs. We demonstrate how a simulation environment, a correctness checker, and a functional coverage metric are all created automatically from a single specification. Additionally, the process exploits the structure of a specification written with simple style rules. The methodology was used to verify a large-scale I/O design from the Stanford FLASH project.
Molecular basis for biosynthesis and accumulation of polyhydroxyalkanoic acids in bacteria (1992)

The current knowledge on the structure and on the organization of polyhydroxyalkanoic acid (PHA)-biosynthetic genes from a wide range of different bacteria, which rely on different pathways for biosynthesis of this storage polyesters, is provided. Molecular data will be shown for genes of Alcaligenes eutrophus, purple non-sulfur bacteria, such as Rhodospirillum rubrum, purple sulfur bacteria, such as Chromatium vinosum, pseudomonads belonging to rRNA homology group I, such as Pseudomonas aeruginosa, Methylobacterium extorquens, and for the Gram-positive bacterium Rhodococcus ruber. Three different types of PHA synthases can be distinguished with respect to their substrate specificity and structure. Strategies for the cloning of PHA synthase structural genes will be outlined which are based on the knowledge of conserved regions of PHA synthase structural genes and of the PHA-biosynthetic routes in bacteria as well as on the heterologous expression of these genes and on the availability of mutants impaired in the accumulation of PHA. In addition, a terminology for the designation of PHAs and of proteins and genes relevant for the metabolism of PHA is suggested.
Inhibition of insulin secretion: A fail-safe system (1993)

Insulin secretion from the beta-cells of the endocrine pancreas is subject to a pot-pourri of stimulatory, modulatory and inhibitory influences. beta-Cell secretion is reduced or blocked by a variety of inhibitors (including galanin, somatostatin and noradrenaline) which reach the cells either via the islet vascular system or are released locally from sympathetic and peptidergic nerves terminating in the pancreas. It is now becoming clear that among these many inhibitors, several have multiple mechanisms by which they inhibit release at the cellular level. Indeed, with multiple inhibitors (some of which are co-secreted) and multiple mechanisms of inhibition, the latter including a late effect in stimulus secretion coupling (perhaps on the exocytotic step per se), inhibition of insulin secretion has the characteristics of a fail-safe system.
In vitro Study into the Influence of X-Ray Beam Angulation on the Detection if Artificial Caries Defects on Bitewing Radiographs (1989)

Little is known about the influence of errors in angulation of the X-ray beam on the correct diagnosis of interproximal caries defects from bitewing radiographs. In this study radiographs were made of 10 artificial lesions resembling initial interproximal caries defects in mandibular teeth at different projection angles within a range of +/- 15 degrees in horizontal and in vertical direction and presented in a random order to 25 dentists. The result show that the best angle for lesion detection was site-specific with about a 7 degrees tolerance range. On the average, best detection performance was achieved with horizontal angulation perpendicular to the tooth surfaces, and vertical angulation with a positive or negative tilt of 12-15 degrees relative to the perpendicular. Deviations from the best horizontal angle resulted mainly in loss of sensitivity, while vertical misangulations caused mainly a drop of the specificity. The classification of lesions with an actual depth less than halfway into the enamel is influenced to a larger extent than that of deeper lesions.
Hysteretic Three‐Step Spin Crossover in a Thermo‐ and Photochromic 3D Pillared Hofmann‐type Metal–Organic Framework (2012)

Multistabilität wird bei einem Metall-organischen Gerüstmaterial beobachtet, das einen einzigartigen dreistufigen Spin-Crossover mit einer thermischen Hysterese von 20 K eingeht (siehe Bild). Der stufenweise Übergang ist mit einer dreistufigen Strukturänderung gekoppelt, die vier spezifische Strukturzustände definiert. Das Material zeigt außerdem einen reversiblen photoinduzierten Spin-Crossover.
Long-Term Clinical and Duplex Follow-up After Proximal Vertebral Artery Reconstruction (1992)

From 1977 to 1989, 28 patients, 18 men and 10 women, underwent 29 proximal vertebral artery reconstructions. Indications were vertebrobasilar insufficiency in 17 patients and TIA or stroke in 6. Five were asymptomatic. Procedures performed were endarterectomy in 20, reimplantation in 5, venous bypass in 3, and decompression in 1 case. Concomitant procedures were coronary artery bypass grafting (6) and carotid, subclavian, or innominate artery revascularization (14). There was no operative mortality. There were 3 early reoperations for occlusion, bleeding, and lymph fistula, respectively. Except for 1 foreign patient recent clinical follow-up was complete. Mean follow-up was 85.6 months (range 17-146). During follow-up 10 patients died. Causes were mainly cardiac (3), carcinoma (3), and stroke (2). Seventeen patients were alive, 13 had no cerebrovascular symptoms, 2 sustained a hemispherical stroke, 1 was only slightly improved, and 1 had a drop attack 131 months after operation. Five and ten-year actuarial survival rates were 85% and 51% respectively. Follow-up with duplex scan was available in 26 patients and was complete in 24. Mean duplex follow-up was 78.6 months (range 3-146). Significant abnormalities were noted in 6 but with symptoms in only 1 patient. Mean time to restenosis was 77.3 months. Late angiographic control in 10 patients correlated well with duplex findings. Proximal vertebral artery reconstruction yields good clinical long-term results, and duplex scan is a useful tool in the follow-up of these patients.
Photoelectron Spectra of Hydrogen-bonded Complexes (1979)

Abstract The photoelectron spectra of typical hydrogen-bonded complexes, CF3COOH–(C2H5)2NCH3, CF3COOH–(n-C3H7)3N, CF3CF2COOH–(C2H5)2NCH3, and CF3CF2COOH–(n-C3H7)3N were observed in the gas phase. It was found that the nonbonding orbital of the proton acceptor is stabilized significantly by hydrogen-bond formation while the three higher occupied orbitals of the proton donor are destabilized. The large orbital energy changes due to hydrogen-bond formation strongly support the charge-transfer model for the hydrogen bond.
Tankyrase-2 oligomerizes with tankyrase-1 and binds to both TRF1 (telomere-repeat-binding factor 1) and IRAP (insulin-responsive aminopeptidase) (2002)

The poly(ADP-ribose) polymerase (PARP) tankyrase-1 contains an ankyrin-repeat domain that binds to various partners, including the telomeric protein TRF1 (telomere-repeat-binding factor 1) and the vesicular protein IRAP (insulin-responsive aminopeptidase). TRF1 binding recruits tankyrase-1 to telomeres and allows its PARP activity to regulate telomere homoeostasis. By contrast, IRAP binding and the Golgi co-localization of tankyrase-1 with IRAP might allow tankyrase-1 to affect the targeting of IRAP-containing vesicles. A closely related protein, tankyrase-2, has also been implicated in vesicular targeting. Unlike tankyrase-1, tankyrase-2 has not been shown to have PARP activity. In addition, it has not been implicated in telomere homoeostasis, because it did not interact with TRF1 in previous studies. Here we show that tankyrase-2 contains intrinsic PARP activity and, like tankryase-1, binds to both TRF1 and IRAP. Our analysis suggests that the ankyrin (ANK) domain of tankyrase-2 comprises five subdomains that provide redundant binding sites for IRAP. Moreover, tankyrase-2 associates and co-localizes with tankyrase-1, suggesting that both tankyrases might function as a complex. Taken together, our findings indicate that tankyrase-1 and tankyrase-2 interact with the same set of proteins and probably mediate overlapping functions, both at telomeres and in vesicular compartments.
Heterogeneity of factor XIIIB: A new method for the determination of factor XIIIB phenotypes by isoelectric focusing in 6 <scp>M</scp> urea (1985)

Abstract Previously reported anomalous results obtained on the separation of the factor XIIIB (F XIIIB*2) allele product have been reinvestigated by thinlayer polyacrylamide gel isoelectric focusing (IEF). The ordinary IEF fails to resolve the difference between the products of F XIIIB*1 and F XIIIB*2 alleles. However, IEF in polyacrylamide gel in the presence of 6 M urea has been found to be a useful method of differentiation between these two allele products.
Histone subunit interactions as investigated by high pressure (1989)

High-pressure fluorescence polarization was used to investigate subunit interactions of the histone H2A-H2B dimer and the H3/H4 tetramer isolated from calf thymus (CT) and chicken erythrocyte (CE) chromatin. The proteins were individually labeled with the fluorescent probe 5-(dimethylamino)-naphthalene-1-sulfonate (dansyl or DNS), and the fluorescence polarization was measured as a function of pressure. The long fluorescence lifetime of the probe allows for the observation of global rotations of the protein, the rate of which is dependent upon the aggregation state. From the pressure dependence of the dansyl polarization, the Kd of H2A-H2B dissociation of the CE dimer was found to be approximately 1 X 10(-7) M at 2.0 M NaCl. Lowering the salt concentration to 200 mM slightly stabilized the protein to 6 X 10(-8) M. Our data indicate a small negative volume change for the dissociation of the core particle octamer. The (H3)2(H4)2 tetramer, as was shown in the previous paper (Royer et al., 1989), also formed predominantly dimers of tetramers at higher protein or salt concentrations. In the study presented here, we found the dissociation constant for the H3/H4 octamer to dimer transition to be 1 X 10(-21) M3 (C1/2 = 4 X 10(-8) M) at 2 M NaCl for the CT preparation. Decreasing the salt concentration to 200 mM reduced the stability of the CT H3/H4 octamer to 9 X 10(-21) M3 (C1/2 = 8 X 10(-8) M). The dimer of the CE tetramer also dissociated upon application of pressure in 2 M salt.(ABSTRACT TRUNCATED AT 250 WORDS)

A micro-monolithic optical pressure sensor for high-pressure hydraulic fluid in transportation (2010)

We present a simple concept for a low-cost pressure transducer. The transducer is a polarimetric device consisting of a pressure sensitive dielectric material in-between polarizing optics. The pressure on the sensitive material creates a stress-induced birefringence which is detected through a change in state of polarization. We show the theoretical behaviour of this device and the various ways of optimizing its sensitivity.
Chronic Hypoxic Pulmonary Hypertension: Is Thrombin Involved? (1993)

Thrombin contracts vascular smooth muscle and stimulates its proliferation. Using a specific thrombin inhibitor, hirudin, we studied whether thrombin contributes to the pulmonary vasoconstriction and vascular proliferation that occurs in pulmonary hypertension. Hirudin was infused intravenously (0.2 mg/h/kg) by minipumps in nine rats during a 3-wk exposure to hypobaric hypoxia (HH). Vehicle (normal saline) was infused in eight hypoxic control (HC) and seven normoxic control (NC) rats. Sufficient hirudin delivery was confirmed by a failure of undiluted plasma from HH, but not from NC and HC, to clot in response to thrombin. When the plasma samples were diluted 1:10, the thrombin time was significantly prolonged in HH when compared with that in both NC and HC. Although hirudin slightly reduced mean pulmonary arterial pressure in open-chest rats, there was no significant difference between the hypoxic groups in total pulmonary resistance, right ventricle weight, morphologic remodeling of lung vessels, or the perfusion pressure-flow relationship in isolated lungs. Vasoconstrictor responses of isolated lungs to angiotensin II and acute hypoxic challenges were not affected by hirudin treatment. We conclude that hirudin, in a dose sufficient to reduce thrombin's catalytic effect on fibrinogen, does not significantly prevent the development of chronic hypoxic pulmonary hypertension.
A new modelling of DC machines taking into account commutation effects (2008)

In some specific manufactured electromechanical applications, power electronic converters must be avoided due to hostile environment. In such a context, stand-alone DC machines are good candidates because of their high reliability and low cost. However, the mechanical commutation is a big problem in this kind of machine especially in high current and low voltage applications. Losses due to arching contacts can be significant. The authors present an original technique to take into account every electrical aspect of brushes contacts (mechanical sliding contact and arching contact). The aim of this study is to determine currents and voltages of conductors during commutation in order to reduce significantly losses due to sliding contact. These evolutions are very important data for finite element analysis too.
Magnétofection™ in vitro et in vivo: une voie vers la thérapie génique (2010)

Gene therapy offers exciting opportunities for the treatment of innate or acquired genetic diseases. However, there is still a need for a safe and efficient strategy to deliver nucleic acids into cells while overcoming the current limitations faced with standard viral vectors. Intensive researches have been carried out over the past decade, focusing both on viral and non-viral (i.e. physical or chemical) strategies. Of these numerous attempts, magnetofection, defined as the combination of nucleic acid vectors with magnetic nanoparticles, holds the promise to achieve high transfection efficiency with reduced toxicity by magnetically focusing the genetic material to be delivered on its cellular target. In vitro as well as in vivo results already demonstrated that this strategy may become a valuable tool towards practical gene therapy.
The Mercury Project: a feasibility study for Internet robots (2000)

Initiated at CERN in 1992, the World Wide Web provides a standard graphical interface to the Internet, and the number of users worldwide has grown exponentially in the last few years. In the Spring of 1994, we conjectured that it might be possible to offer public access to a teleoperated robot via the WWW. As a feasibility study in 1994, we built a system that allows a robot manipulator to be teleoperated via the Internet. Although the field of teleoperation dates back over 50 years, HTTP provides a low-cost and widely available interface that can make teleoperated resources accessible to a broad range of users. The Mercury Project consisted of an industrial robot arm fitted with a CCD camera and a pneumatic system. We placed a sandbox filled with buried artifacts in the robot workspace. Novice users remotely moved the camera to view desired locations and directed short bursts of compressed air into the sand to view the newly cleared regions. To our knowledge, the Mercury Project was the first Internet robot. It was available almost continuously from August 1994 through March 1995 and was accessed by over 50,000 unique hosts. The article focuses on the interface design, robot hardware, and architecture of the system.
