Le germplasm des rutacées de l'île de la Réunion : sa gestion et son évaluation (1993)

Le germplasm des rutacées présent à la Réunion comporte 144 lignées dont des variétés introduites et endémiques ainsi que différentes lignées de porte-greffe introduites sous forme de semences. Ce matériel végétal est évalué pour ses performances agronomiques et son comportement vis-à-vis du chancre bactérien et du virus de la tristeza des agrumes. La majorité des greffons nécessaires à l'approvisonnement des pépinières est prélevée dans le parc à bois dont l'état sanitaire est donc très rigoureusement contrôlé
The temperature dependence of the conductivity in the critical regime of the metal - insulator transition in conducting polymers (1997)

The metal - insulator (M - I) transition in conducting polymers is particularly interesting; critical behaviour has been observed over a relatively wide temperature range in a number of systems, including polyacetylene , polypyrrole (PPy), poly(p-phenylenevinylene) (PPV), and polyaniline (PANI). In each case, the metallic, critical, and insulating regimes near the M - I transition have been identified from plots of versus T: in the metallic and insulating regimes W(T) exhibits positive and negative temperature coefficients, respectively, while in the critical regime W(T) is temperature independent. Thus, in the critical regime, the conductivity follows a power law, , where is the critical exponent which is predicted by scaling theory to be between one-third and unity. In conducting polymers, the critical regime is easily tunable by varying the extent of disorder, or by applying external pressure and/or magnetic fields. The transitions from metallic to critical behaviour and from critical to insulating behaviour have been induced with a magnetic field, and that from insulating to critical and then to metallic behaviour with increasing external pressure. The detailed evolution of in the critical regime at low temperatures can be observed in W(T) plots as the system is changed from metal to insulator. Although W(T) is temperature independent for a wide range of temperatures below 50 K, systematically increases from values less than one-third on the metallic side towards unity as the system is moved toward the insulating side.
P b -type interface defects in (100)Si/SiO2 structures grown in ozonated water solution (2003)

Si dangling bond interface defects (Pb0,Pb1) were probed by electron spin resonance in entities of (100)Si with ultrathin SiO2 grown in ozonated de-ionized water solution at room temperature. After photodesorption of passivating hydrogen, Pb0 appears with densities up to ∼5×1012 cm−2, a value five times larger than the one standardly attained with high temperature thermal growth. Thus standard quality thermal Si/SiO2 interface properties, as exposed by the Pb0-type defects criterion (interface traps), are not obtained by oxidation in ozonated water solutions at room temperature. The interface quality may be upgraded by providing additional thermal budget. Yet standard qualitity is still not attained after vacuum annealing at 600 °C.
Automatic High-Dynamic Range Image Generation for Dynamic Scenes (2008)

Automatic high-dynamic range image generation from low- dynamic range images offers a solution to conventional methods, which require a static scene. The method consists of two modules: a camera-alignment module and a movement detector, which removes the ghosting effects in the HDRI created by moving objects.
A Framework for Remote Execution and Visualization of Cell-DEVS Models (2003)

Simulation is becoming increasingly important in the analysis and design of complex systems with natural and artificial components. CD++ is a modeling and simulation tool that was created to study these kinds of systems by using a discrete event cell-based approach. It was successfully employed to define a variety of models for complex applications. Here, the authors present different extensions done to the tool using a client-server architecture. Users can create models in local workstations, execute them in a remote high-performance simulation engine, and then receive, visualize, and analyze the results locally with easy-to-use 2D and 3D interfaces. The 3D interface was built using the virtual reality markup language (VRML) to facilitate Web-based visualization. The tool now enables running several models simultaneously and supports multiview outputs.
A Novel Halo Orthosis to Reduce Pin Loosening (2008)

Pin loosening is a frequent complication associated with the use of halo orthoses. Efforts to reduce pin loosening incidence include increasing the number of halo pins, increasing the torque specification, and proactively retightening the halo pins. Although these approaches lower pin loosening incidence rates, none addresses the cause of pin loosening, which is the inability of current halo ring designs to accommodate changes in geometry of the skull. A novel four-pin adaptive halo ring is introduced that can accommodate changes in geometry of the skull and provide a nearly constant pin force. To quantify pin loosening in a halo ring, tests were performed using a fixture that was capable of simulating the changes in skull geometry that are responsible for pin loosening. Both the four-pin adaptive halo and a conventional halo were tested. After 1.1mm of radial recession of the skull at the pin site, the average halo pin force in the conventional halo decreased by 78% while the average halo pin force in the four-pin adaptive halo decreased by 12%. In addition, the four-pin adaptive halo had significantly less variation in initial halo pin force (p-value <0.0001) than that of the four-pin adaptive halo.
Design And Analysis Of Optical Systems For The Stanford/MSFC Multi-Spectral Solar Telescope Array (1989)

We report on the design and the theoretical ray trace analysis of the optical systems which will comprise the primary imaging components for the Stanford/MSFC Multi-Spectral Solar Telescope Array (MSSTA). This instrument is being developed for ultra-high resolution investigations of the Sun from a sounding rocket. We have analyzed doubly reflecting systems of sphere-sphere, ellipsoid-sphere (Dail-Kirkham), paraboloid-hyperboloid (Cassegrain), and hyperboloid-hyperboloid (Ritchey-Chretien) configurations. For these mirror systems, we have performed ray trace analysis and generated through-focus spot diagrams, point spread function plots, and geometrical and diffraction MTFs. The results of these studies will be presented along with the parameters of the Ritchey-Chretien optical system selected for the MSSTA flight. The payload, which incorporates seven of these Ritchey-Chretien systems, is now being prepared for launch in late September 1989.
On the Hydrolysis and Alcoholysis of Quinazoline-2-carbonitrile Derivatives (1959)

Radziszewski reaction of 4-methoxy- (I), 4-ethoxy- (III), 4-butoxy- (V), and 4-benzyloxy-quinazoline-2-carbonitrile (VII) affords 4-methoxy- (II), 4-ethoxy- (IV), 4-butoxy- (VI), and 4-benzyloxy-quinazoline-2-carbonamide (VIII) in a good yield. Alcoholysis of (III), (V), quinoline-2-carbonitrile (IX), quinoline-4-carbonitrile (XII), and benzonitrile (XX) was carried out. The nitrile was dissolved in dry ethanol, dry hydrogen chloride was saturated in this solution, and the hygroscopic crystals thereby obtained were treated with acid or alkali. Treatment with acid afforded acid amide in the majority, with a minute amount of ester, while treatment with alkali resulted in larger formation of the ester. It was also found that the nitriles of quinazoline and quinoline series tended to form acid amide.
[Acute myocardial infarction in young patients--severe failures in the system of acute and secondary care]. (2012)

In patients who suffered AMI in young age, risk factors are dominated by smoking and positive family history of CV diseases. One fifth of patients suffer from other underlying disease (inflammatory disease, malignancies, combined thrombophilia) or have another precipitating factor (febrile disease, drug abuse). The acute care seems unsatisfactory due to late arrival of most patients to catheterization laboratories (underestimation of the disease, incorrect initial diagnosis). Subsequent therapy is well composed but lacks in intensity.

A Super Compact $2\times 2$ MIMO Antenna for GSM/WLAN Applications (2018)

This paper presents a highly compact four elements multiple input multiple output (MIMO) antenna with triple band radiation characteristics. The proposed MIMO antenna consists of a spiral shaped radiating element and a modified ground plane. The antenna resonates at 1.8 GHz (1.75-1.82 GHz), 3.7 GHz (3.67-3.84 GHz) and 5.3 GHz (5.17-5.47 GHz) covering GSM and WLAN application bands. The isolation in the proposed MIMO antenna is achieved by means of the orthogonal arrangement of radiators and by using square ring shaped decoupling element. The designed antenna shows bidirectional radiation characteristics.
Realization of Bragg grating based integrated fractional photonic Hilbert transformer (2015)

Wideband integrated fractional order photonic Hilbert transformer (FrPHT) is proposed and demonstrated, by using single apodized Bragg gratings with phase shifts in a silica-on-silicon planar platform. Effects of apodization profiles and operation bandwidths are analyzed.
Modulation in spinal circuits and corticospinal connections following nerve stimulation and operant conditioning (2006)

Neural plasticity occurs throughout adult life. In healthy individuals, different spinal pathways are differently modulated during different daily activities. Drastic changes to nervous system activity and connections caused by injuries or diseases alter spinal reflexes, and this is often related to disturbed motor functions. In both health and disease, spinal reflexes are subject to substantial modifications. Plasticity in supraspinal descending connections is even more remarkable; corticospinal connectivity has been shown to be extremely plastic. In this session, we describe two approaches for possibly improving recovery after central nervous system (CNS) lesions. They are very different, but both involve repetitive nerve stimulation and CNS plasticity. The first approach is functional electrical stimulation (FES) of the common peroneal nerve, which has been used to treat foot drop in patients with CNS lesions. The second approach is operant conditioning of a spinal reflex. Spinal reflex operant conditioning studies in animal models have shown plastic changes in spinal cord neurons associated with this form of learning and improved locomotor function in incomplete spinal cord injured rats. Thus, reflex conditioning might be a robust approach to inducing plasticity at spinal and supraspinal levels. As a first step in establishing this approach and characterizing its effects in the human adult CNS, we are currently investigating the extent and time course of operant conditioning of the soleus H-reflex in healthy subjects.
Agency and AI in Consulting: Pathways to Prioritize Agency‐Enhancing Automations (2019)

Amidst the advances of AI and automation, this paper provides a framework for ethnographic methods and insights to enhance human agency at work. Through analyzing data collected from ethnographic immersions in three different consulting firms (a professional services firm, a management consultancy, and a boutique insights agency), human‐agent decisions are isolated in case studies and the pathways of unlocking the potential of automation to enhance the agency of individuals rather than constraining it are highlighted. Through drawing a distinction between thinking agency and executional agency present in the work of a consultant, this paper argues that automations that preserve thinking agency while maximizing productivity and accuracy are the solutions that should be adopted. Through vetting workflows sourced from ethnographic immersions with the established criteria, a framework for consultancies – and more broadly businesses – to better employ AI and automation is laid out and substantiated by an account of how anthropological approaches can be brought in to assist the process of prioritization among contextual automation processes.
Mutational analysis of the highly conserved C‐terminal residues of the XylS protein, a member of the AraC family of transcriptional regulators (2000)

The XylS protein of the TOL plasmid of Pseudomonas putida belongs to the so-called AraC/XylS family of regulators, that includes more than 100 different bacterial proteins. A conserved stretch of about 100 amino acids is present at the C-terminal end. This conserved region is believed to contain seven alpha-helices, including two helix-turn-helix (HTH) DNA binding motifs (alpha(2)-T-alpha(3) and alpha(5)-Talpha-(6)), connected by a linker alpha-helix (alpha(4)), and two flanking alpha-helices (alpha(1) and alpha(7)). The second HTH motif is the region with the highest homology in the proteins of the family, with certain residues showing almost 90% identity. We have constructed XylS single mutants in the most conserved residues and have analysed their ability to stimulate transcription from its cognate promoter, Pm, fused to 'lacZ. The analysis revealed that mutations in the alpha(5)-helix conserved residues had little effect on the XylS transcriptional activity, whereas the distribution of polarity in the alpha(6)-helix was important for the activity. The strongest effect of the mutations was observed in conserved residues located outside the DNA binding domain, namely, Gly-290 in the turn between the two helices, Pro-309 located downstream of alpha(6), and Leu-313, in the small last helix alpha(7), that seems to play an important role in the activation of RNA-polymerase. Our analysis shows that conservation of amino acids in the family reflects structural requirements rather than functionality in specific DNA interactions.
Bacteremia Due to<i>Clostridium hathewayi</i>in a Patient with Acute Appendicitis (2004)

Clostridium hathewayi is a newly described Clostridium species isolated from the feces of healthy human individuals, but its clinical significance is not known. We describe a case of human infection associated with C. hathewayi. The bacterium (strain HKU18) was isolated from the blood culture of a 39-year-old patient with acute gangrenous appendicitis complicated by septic shock. The cells were strictly anaerobic, nonmotile rods that stained gram negative. Conventional phenotypic tests and commercial identification systems failed to identify HKU18 to the species level. 16S rRNA gene analysis showed 1.4% nucleotide difference between the sequence of HKU18 and that of C. hathewayi, indicating that HKU18 was a strain of C. hathewayi. The patient responded to appendectomy and antibiotic treatment. 16S rRNA gene sequencing would be useful in further characterizing the clinical disease spectrum of C. hathewayi.
Induction of high mobility group box 1 release from serotonin-stimulated human umbilical vein endothelial cells (1998)

High mobility group box 1 (HMGB1) is a non-histone nuclear protein which is released from the nucleus of activated macrophages into the extracellular space in response to stimuli such as endotoxin or necrosis. The HMGB1 functions as a potent proinflammatory cytokine in the extracellular spaces. Recently, HMGB1 has been implicated in the progression of atherosclerosis. However, the association between HMGB1 and the development of atherosclerosis is poorly understood. Therefore, we examined whether serotonin (5-HT), a key factor involved in the development of atherosclerosis, induced HMGB1 release in human umbilical vein endothelial cells (HUVECs). We found that 5-HT induced the release of HMGB1 but not of ERK1/2 and JNK from HUVECs via the 5-HT receptor (5-HT1B)/p38 mitogen-activated protein kinase (MAPK) signaling pathway. The p38MAPK inhibitor SB203580 and the 5-HT1B antagonist GR55526 markedly inhibited HMGB1 release from 5-HT-stimulated HUVECs. The vascular endothelial growth factor (VEGF) derived from activated macrophages in atherosclerotic lesions also plays an important role in the progression of atherosclerosis. We found that HMGB1 induced VEGF production in macrophage-like RAW264.7 cells. HMGB1 induced the activation of p38MAPK, ERK1/2 and Akt. The PI3-kinase inhibitor LY294002 significantly inhibited VEGF production in HMGB1-stimulated macrophages, while other kinase inhibitors did not. These results suggest that HMGB1 release may contribute as a risk factor in the development and progression of atherosclerosis.

Analysis of retroviral sequences in the spinal form of multiple sclerosis (1991)

The polymerase chain reaction was used, in a blind study, to look for retroviral sequences in DNA extracted from the peripheral blood mononuclear cells of 11 patients with the spinal form of multiple sclerosis (MS). Control subjects consisted of 7 patients with other neurological diseases and 5 healthy blood donors. Three sets of oligonucleotides were used. They could detect all known human oncoretroviruses, lentiviruses, or spumaretroviruses. The primers recognized conserved sequences in the long terminal repeats of the proviral DNA. Control experiments showed that the primers crossreacted within the human immunodeficiency virus or human T-cell lymphotropic virus group and that they provided the expected level of sensitivity. Therefore the assay could have detected not only known human retroviruses but also new related members. In spite of this, no retroviral sequences were detected in either the MS or the control specimen.
Emergency department ‘undercrowding’ is associated with decreased waiting times (2016)

Patient presentation numbers are strongly associated with and likely impact on median waiting time. Understanding that controlling demand can lead to significant benefits in patient processing, flow and overall patient perceived level of care and satisfaction is relevant to any discussion on ED overcrowding and the deleterious effects of access block.

Measurements of Randomly Placed Wireless Transmitters Used as an Array for Receivers Located Within the Array Volume With Application to Emergency Responders (2009)

Emergency responders often experience poor quality wireless communications due to the complex radio-frequency propagation environment encountered at a typical emergency response location, such as an apartment complex, office building, or other large building structure. Our previous theoretical analysis in conjunction with simulation studies suggests that optimizing arrays of randomly located wireless transmitters can provide a significant increase in the received signal level for a receiver located in the array volume. Here we present experimental results from the application of our initial algorithm in representative complex propagation environments. Several different scenarios are included in the experiments to demonstrate the effectiveness of the optimization approach in an environment that contains a variety of scattering objects. For the various scenarios, we observed at least a 7 dB median gain over a single transmitter when the array consists of four transmitters.
Removal of Thermal Barrier Coatings From Turbine Blades: A Comparison of Mechanical and Chemical Methods (2001)

Abstract Thermal barrier coatings are gaining considerable importance for the improvement the energetic efficiency of turbines. These materials are often applied on the surface of blades and are based on a layer of antioxidation material (mainly MCrAlY alloys) and a top layer that acts as proper thermal barrier (normally Yttria partially stabilized Zirconia). Coating removal is an important aspect in the production of these blades. "Decoating" or "stripping" is needed for the production of new components as well as for the reconditioning of existing ones. The present paper is dedicated to the comparison of different stripping methods and to the characterization of the blades surface after removal of thermal spray coatings both of Zirconia and of MCrAlY. The results reported here show that chemical stripping is particularly suitable for MCrAlY coating removal and does not affect the substrate. Water jet stripping can successfully be used for Zirconia-MCrAlY system removal although care is needed to avoid substrate damage. Salt bath technologies have been formed to be effective for TBC removal but not for MCrAlY removal.
