Active piezoelectric vibration control for high speed switched reluctance machine (2007)

This paper presents an active compensation method of mechanical and aerodynamic vibrations for high speed switched reluctance machines (SRM). This method consists in sticking two piezoelectric bars on the external surface of the stator. These ones are controlled considering the vibratory acceleration of a particular structure point. This method allows the reduction of the vibratory acceleration due to aerodynamic, mechanical and magnetic phenomena of the studied structure and then the decrease of generated acoustic noise.
Reaction between Salicylic Acid and Zinc Oxide in the Presence of Water. (1964)

For the explanation of chemical changes and loss of dermatological activity of salicylic acid in external preparations containing salicylic acid and zinc oxide, systems composed of salicylic acid, zinc oxide, and water were investigated. By the determination of salicylic acid and zinc ion in the aqueous phase after an equilibrium state was attained, the formation of 1 : 1 and 2 : 1 salts of salicylic acid and zinc was ascertained quantitatively.

Intravital Co-Imaging of Oxygen Tension and Immune Response in Leukemia using 2-Photon PLIM (2017)

Abstract Tumor infiltrating lymphocytes (TILs) must compete with cancer cells for metabolic resources that become depleted in result of cancerous metabolism and compromised blood supply. In bone marrow, highly proliferative acute leukemias utilize oxidative phosphorylation and deplete local oxygen supply resulting in bone marrow hypoxia which contributes to therapeutic resistance. We aim to decipher the role that metabolic reprogramming of leukemic blasts plays in modulating the bone marrow microenvironment, particularly the impact on local oxygen tension, and how this affects the anti-leukemia immune response. To characterize the spatiotemporal dynamics of leukemia infiltrating T cells during disease progression, and determine the impact of oxygen tension, OxPhos, and OxPhos inhibition on T cell function inside the leukemic bone marrow, we have utilized a novel oxygen probe, PtP-C343, and intravital 2-photon phosphorescence lifetime microscopy (2p-PLIM). Our initial results demonstrate sufficient spatial and temporal resolution of the combination 2p-PLIM to simultaneously reveal intravital oxygen gradients and track lymphocytes in single cell resolution. The combination 2p-PLIM and in vivo cell tracking will enable to study the dynamic regulation of the migratory behavior of cancer-infiltrating T lymphocytes by the intratumoral oxygen tension gradients.
Digital distance relay with improved characteristics against distorted transient waveforms (1989)

A microprocessor-based digital distance relay with improved performance in relation to low-frequency transient oscillation is introduced. New calculation algorithms for the distance element and directional element are discussed. This distance element delivers high measurement performance with an error of less than +or-3% against distorted transient waveforms containing low-frequency spectral components using a modified differential approximation algorithm based on a differential equation. The directional element utilizes a pseudo-vector product that is not affected by distortion waves for reliable direction judgement.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
X-Ray Powder Diffraction Data for Seventeen Local Anesthetics (1972)

Abstract X-ray powder diffraction data for some local anesthetics have been obtained by the Debye-Scherrer technique. The data for individual local anesthetics are tabulated in terms of lattice spacings (d in Å) and the relative intensities of lines. In addition, a classification is provided of the 3 most intense lines for each of the local anesthetics, with their relative intensities arranged in descending numerical order with regard to d spacing of the most intense line from each pattern.
Bendamustine (2009)

Alkylating agents form the basis of most combination treatment regimens for low-grade lymphoproliferative disorders. Bendamustine is a unique alkylating agent that has distinctive preclinical activity in cell lines resistant to other alkylators. Furthermore, clinical activity has been demonstrated in patients with alkylating agent resistant disease. Recently, larger studies have been organized to study the clinical effects of bendamustine further. In indolent B-cell non-Hodgkin lymphoma that is resistant to rituximab, bendamustine induced a remission in 77% of patients. Myelosuppression was identified as the most common toxicity. In 2 studies of similar populations of patients, the combination of bendamustine and rituximab induced remission 90% of patients with a median progression-free survival of 23-24 months. The overall remission rate was 59% in a prospective, randomized study of untreated patients with chronic lymphocytic leukemia, which was significantly greater than the rate of 26% in the chlorambucil control arm (P < 0.001). Combined with rituximab, bendamustine induces a remission in 67% of patients with relapsed or refractory chronic lymphocytic leukemia. Bendamustine is an active agent for the treatment of low-grade lymphoproliferative disorders and more study is needed to determine which dose and schedule is optimal, and which patients will derive the greatest benefit from its use.
An ISOCAM survey of nearby star formation regions (1999)

Several nearby star formation regions have been surveyed in two ISOCAM bands (centred at 6.7 and 14.3 m). Stars with cicumstellar emission are effectively separated from reddened background stars and in general the number of new young stellar sources is comparable to the number of previously known within the mapped regions. Most of these new YSOs are faint and we discuss the implication as regards the initial mass function (IMF) for the Cha I region. We find that the IMF rises slowly (logarithmic index = \\Gamma0:2) towards sub-stellar masses. Test cases confirm that this ISOCAM survey reveals many brown dwarfs in the closest star formation regions.
Mutagenic and genotoxic effects of mate (Ilex paraguariensis) in prokaryotic organisms. (1994)

1. The mutagenic and genotoxic effects of mate (Ilex paraguariensis) aqueous solutions were analyzed in bacterial cells. 2. Mate solutions showed mutagenic activity in the Ames test (TA97, TA98, TA100 and TA102 strains) at concentrations of 20 to 50 mg/plate (mutagenic factors of 3.5 to 5.6) and genotoxic activity in the inductest (WP2s (lambda) strain), with a maximal phage induction at concentrations of 10 to 20 mg/plate. Above these concentrations the mate solutions were cytotoxic. 3. Addition of 5 U/ml catalase, 20 microliters/ml S9 rat liver microsomal fraction, 100 mM thiourea or 10 mM dipyridyl completely inhibited the lysogenic induction produced by mate; however, the addition of 1,000 U/ml superoxide dismutase was almost ineffective. 4. Oxygen reactive species may be present in mate solutions playing an essential role in its genotoxicity.

Biotransformation fongique des xénobiotiques : du sol au gène (2001)

Les objectifs de notre programme de recherche sont de préciser les mécanismes qui gouvernent le devenir des xénobiotiques dans les sols, et de proposer des procédés innovants de dépollution. En ce qui concerne les réactions de biotransformation, nous focalisons plus particulièrement nos recherches sur les capacités métaboliques des champignons filamenteux. Les polluants considérés sont des pesticides, des produits à usage vétérinaire, des polluants industriels ou domestiques, présentant souvent un caractère toxique avéré.Au cours des études réalisées dans les sols ou en milieu liquide, la transformation des xénobiotiques par des champignons filamenteux appartenant aux différents groupes taxonomiques est évaluée en fonction de critères physico-chimiques (température, pH, présence de surfactants…). Nous avons développé des outils afin de sélectionner les souches les plus performantes vis à vis de la dégradation de xénobiotiques particuliers, d'inoculer ces souches dans des sols non stériles et d'assurer leur survie ou maintien dans les sols pendant plusieurs semaines.En général, les résultats obtenus montrent que la minéralisation des xénobiotiques est faible en présence des champignons seuls, mais que ces derniers synergisent la minéralisation microbienne. D'autre part, les champignons oxydent les xénobiotiques en composés qui semblent de bons substrats pour les populations microbiennes. Les souches fongiques que nous avons sélectionnées, après inoculation, se développent rapidement dans des sols agricoles ou industriels. Cependant, les réactions de transformation restent limitées par la biodisponibilité des polluants.Nos résultats permettent d'impliquer dans certaines réactions d'oxydation des enzymes exocellulaires (peroxydases, laccases), mais aussi des cytochromes P450 intracellulaires. Nous avons purifié et caractérisé certaines formes de laccases dont nous cherchons à déterminer la structure (homogénéité protéique, taux de glycosylation,…) ainsi que leur mode d’action selon le type de substrat pris en compte (rôle des médiateurs redox, formes réactives,…).Les laccases ont un potentiel d’oxydation inférieur à celui de certains des polluants à transformer. Ces substrats potentiels ne sont alors que peu ou pas transformés. L’activité catalytique des enzymes peut être augmentée par ajout d’un médiateur redox, jouant le rôle de transporteurs d’électrons entre l’enzyme et son substrat. L’optimisation de l’activité des laccases, par mutagénèse dirigée ou aléatoire, constitue une seconde voie de recherches.
Design, Synthesis, Derivatization, and Structure−Activity Relationships of Simplified, Tricyclic, 1,2,4-Trioxane Alcohol Analogues of the Antimalarial Artemisinin (1998)

Novel C4-(hydroxyalkyl)trioxanes 5d and 5e were designed and synthesized based on an understanding of the molecular mechanism of action of similar 1,2,4-trioxanes structurally related to the antimalarial natural product artemisinin (1). In vitro efficacies of these two new pairs of C4-diastereomers against chloroquine-sensitive Plasmodium falciparum support conclusions about the importance to antimalarial activity of formation of a C4 radical by a 1,5-hydrogen atom abstraction. Derivatives 6, 7, and 21 of C4β-substituted trioxane alcohols 4a, 5d, and 5e were prepared, each in a single-step, high-yielding transformation. Four of these new analogues, 6a−c and 7, are potent in vitro antimalarials, having 140 to 50% of the efficacy of the natural trioxane artemisinin (1).

Detection of Human Monkeypox in the Republic of the Congo Following Intensive Community Education (2013)

Monkeypox is an acute viral infection with a clinical course resembling smallpox. It is endemic in northern and central Democratic Republic of the Congo (DRC), but it is reported only sporadically in neighboring Republic of the Congo (ROC). In October 2009, interethnic violence in northwestern DRC precipitated the movement of refugees across the Ubangi River into ROC. The influx of refugees into ROC heightened concerns about monkeypox in the area, because of the possibility that the virus could be imported, or that incidence could increase caused by food insecurity and over reliance on bush meat. As part of a broad-based campaign to improve health standards in refugee settlement areas, the United Nations International Children's Emergency Fund (UNICEF) sponsored a program of intensive community education that included modules on monkeypox recognition and prevention. In the 6 months immediately following the outreach, 10 suspected cases of monkeypox were reported to health authorities. Laboratory testing confirmed monkeypox virus infection in two individuals, one of whom was part of a cluster of four suspected cases identified retrospectively. Anecdotes collected at the time of case reporting suggest that the outreach campaign contributed to detection of suspected cases of monkeypox.
Analysis of single-mode yields above threshold for complex-coupled distributed feedback lasers with asymmetric facet reflectivities (2005)

Single-mode yields above threshold of complex-coupled (CC) distributed feedback (DFB) lasers with antireflection and high-reflection-coated facets for various values of ∣kL∣ and coupling coefficient ratio (CR) are presented and compared with the spatial hole burning- (SHB-) corrected yield at threshold. If the criterion necessary for the SHB-corrected yield is selected properly, the two yields give good agreement. We present two single-mode yields above threshold, showing the difference between in-phase (IP) and antiphase (AP) CC DFB lasers, even though the two yields are the same at threshold. Single-mode yields above threshold of IP CC DFB lasers are higher than those of AP CC DFB lasers, since the threshold gain of the next strongest mode of AP CC DFB lasers, increases rapidly compared with that of IP CC DFB lasers because of the SHB effect. As the CR increases, the single-mode yield of IP CC DFB lasers initially increases and has a nearly constant value of more than 90% for a CR greater than or equal to 0.3. As the CR and ∣kL∣ increase, the effect of the reflectivity of the antireflection facet on the single-mode yield decreases.
5-HT4 Receptors (2004)

Serotonin 4 receptors (5-HT(4)Rs) were discovered 15 years ago. They are coded by a very complex gene (700Kb, 38 exons) which generates eight carboxy-terminal variants (a, b, c, d, e, f, g, n). Their sequences differ after position L(358). Another variant is characterized by a 14 residue insertion within the extracellular loop 2. Highly selective potent 5-HT(4) receptor antagonists and partial agonists which cross the blood-brain barrier have been synthesized, but a specific full agonist for brain studies is still missing. Based on physiological and behavioral experiments, 5-HT(4)Rs may be targets to treat cognitive deficits, abdominal pain and feeding disorders. One 5-HT(4)R-directed drug (SL65.0155) is already in phase II to treat patients suffering from memory deficits or dementia.

Fusion of depth maps with multiple scales (2011)

Multi-view stereo systems can produce depth maps with large variations in viewing parameters, yielding vastly different sampling rates of the observed surface. We present a new method for surface reconstruction by integrating a set of registered depth maps with dramatically varying sampling rate. The method is based on the construction of a hierarchical signed distance field represented in an incomplete primal octree by incrementally adding triangulated depth maps. Due to the adaptive data structure, our algorithm is able to handle depth maps with varying scale and to consistently represent coarse, low-resolution regions as well as small details contained in high-resolution depth maps. A final surface mesh is extracted from the distance field by construction of a tetrahedral complex from the scattered signed distance values and applying the Marching Tetra-hedra algorithm on the partition. The output is an adaptive triangle mesh that seamlessly connects coarse and highly detailed regions while avoiding filling areas without suitable input data.
Annealed high band gap tunnel junctions with peak current densities above 800 A/cm2 (2016)

The development of high-performance high band gap tunnel junctions is critical for producing efficient multijunction photovoltaic cells that can operate at high solar concentrations. The n-InGaP/GaAs/p-AlGaAs TJ has been demonstrated to produce peak tunneling currents (J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pk</sub> ) above 1000 A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> with minimal absorption losses due to the use of thin (≤50 Å) GaAs layer. We will report on the growth and device modeling of these structures as well as the effect of high temperature annealing on J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pk</sub> . A method to grow TJ structures resistant to annealing will be described, which has resulted in thermally annealed TJ with J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pk</sub> above 800 A/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . This is the highest value ever reported for an annealed high band gap TJ. Device modeling has been used to investigate the source of the high tunneling current, as well as the behavior of the annealed TJ.

De Novo Synthesis of Long-Wavelength Absorbing Chlorin-13,15-dicarboximides (2010)

Chlorins bearing a six-membered imide ring spanning positions 13-15, commonly referred to as purpurinimides, exhibit long-wavelength absorption yet have heretofore only been available via semisynthesis from naturally occurring chlorophylls. A concise route to synthetic chlorins, which bear a geminal dimethyl group in the pyrroline ring, has been extended to provide access to chlorin-13,15-dicarboximides. The new route entails (i) synthesis of a 13-bromochlorin, (ii) palladium-catalyzed carbamoylation at the 13-position, (iii) regioselective 15-bromination under acidic conditions, and (iv) one-flask palladium-mediated carbonylation and ring closure to form the imide. In some cases the ring closure reaction afforded the isomeric (and readily separable) chlorin-isoimide in addition to the chlorin-imide. The resulting chlorin-imides and chlorin-isoimides exhibit long-wavelength absorption (679-715 nm) and emission (683-720 nm) in the far-red and near-infrared spectral region. The absorption of the chlorin-(iso)imides fills the spectral window between that of analogous synthetic chlorins and 13(1)-oxophorbines (603-687 nm) and bacteriochlorins (707-792 nm). The synthetic versatility of the de novo route complements the existing semisynthetic route from chlorophylls and should enable fundamental spectroscopic studies and photochemical applications.
Identifiability Issues for Parameter-Varying and Multidimensional Linear Systems (1997)

Abstract This paper considers the identifiability of state space models for a system that is expressed as a linear fractional transformation (LFT): a constant matrix (containing identified parameters) in feedback with a finite-dimensional, block-diagonal (“structured”) linear operator. This model structure can represent linear time-invariant, linear parameter-varying, uncertain, and multidimensional systems. Families of input-output equivalent realizations are characterized as manifolds in the parameter space whose tangent spaces — and orthogonal complements — can be obtained via singular value decomposition. As illustrated by a numerical example, restricting iterative parameter estimation algorithms (e.g., maximum-likelihood with nonlinear programming) to the orthogonal directions offers significant computational advantages.
