Analysis of bidirectional information transfer on drumming ensemble using robotic session system (2012)

For the design of artificial systems with the ability to co-create with humans, it is necessary to consider how robots interpret and apply its human partner's actions in its own actions. Nowadays many robots with the ability to co-create with human appeared but few research succeeded in quantifying the interaction between humans and robots, making it difficult to assess the importance of the robot's contribution to the interaction.
A DVI Previewer in Java (2006)

A DVI file is the standard output of the TeX typesetting system. My\nthesis explores the possibility of creating a complete DVI file\npreviewer on the Java platform. I have taken a close look at the\nvarious issues that had to be overcome, proposed and discussed\nsolutions, and for the most part ended up with an implementation. I\nhave found Java to be well suited an application like this, with its\nrich graphics API, especially with regard to font and shape\nprocessing. The final result has been a working DVI previewer which,\nin my opinion, with a little more tuning, will be a good alternative\nto the major previewers in the TeX world - on any operating system.

Joint amplitude and timing estimation for scintillation pulses in GPU (2016)

We present an implementation on a graphics processing unit (GPUs) of a maximum-likelihood (ML) contracting-grid algorithm that performs joint estimation of amplitude and time of scintillation pulses. ML estimation consists in finding the parameters that maximizes the likelihood. We proposed a multivariate normal model for the likelihood, which implies that we need mean pulses and covariance matrices for every parameter variation. In a previous work, we performed a Fisher information analysis to determine the minimum number of samples that contains the most timing information in a digital pulse, for a given acquisition rate. Here, we use just the right amount of samples to reduce the size of mean pulses and covariance matrices. In order to reduce the number of precomputed mean pulses and covariance matrices, we take advantage of the linearity of scintillation pulses, which allows us to scale a normalized pulse to obtain mean pulses of any amplitude. We make use of this information to limit the amount of computation and shared memory used in our GPU code, while preserving full timing performance. We developed our code on an Nvidia Tesla C2075 GPU and we were able to process 1.5 million events per second. The estimation algorithm and GPU implementation can be used in real-time for systems that require high temporal resolution such as time-of-flight positron emission tomography or in processes that have high gamma-ray count rate.

Étude expérimentale de l'influence du blocage aval sur les performances d'un ventilateur axial (2013)

L’étude a pour objet d’aider au développement d’une méthode de pré-dimensionnement des ventilateurs opérant en champs contraints. L’influence d’un obstacle situé à l’aval d’un ventilateur axial est étudiée expérimentalement sur quatre rotors de vitesses angulaires spécifiques différentes. Les rotors sont testés sur banc d’essais normalisé du type caisson aspirant. Les rotors fonctionnent en champ libres et en champs contraints par 15 configurations de blocages différentes. Les blocages sont réalisés par une plaque plane, perpendiculaire à l’axe de rotation du rotor, modélisant par exemple l’obstruction d’un bloc moteur automobile à combustion interne. Les quatre jeux de performances globales (élévation de pression, débit et rendement statique) évoluant avec la distance à l’obstacle sont comparés pour mettre en évidence leurs similarités. On observe des variations d’élévation de pression en fonction du débit qui sont plus rapides quand l’obstacle se rapproche du ventilateur. Les courbes caractéristiques semblent évoluer autour d’un pivot dont la position par rapport au débit nominal du rotor en champ libre parait être en relation avec la vitesse angulaire spécifique.

Fujitsu has developed an optical flying head (OFH) containing a thin-film coil and a high numerical aperture lens for magneto-optical (MO) disk drives. Experiments show successful writing and reading MO media. We explain the design and testing of the OFH.
Incidence, timing and risk factors of type 1 retinopathy of prematurity in a North American cohort (2020)

Type 1 ROP developed in about 6% of premature infants over wide time windows in terms of both PMA and PNA. BW and GA are the dominant risk factors for type 1 ROP, while other prenatal factors add minimal predictive power for type 1 ROP.
Preparation and characterization ofBxC1−xthin films with the graphite structure (1992)

Using chemical vapor deposition (CVD), we have prepared ${\mathrm{B}}_{\mathit{x}}$${\mathrm{C}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$ solid solutions for 0x0.17, which have the graphite structure. By varying the relative proportions of benzene and boron trichloride in the CVD reactor, we are able to control the boron concentration in our thin-film samples. Grazing-incidence x-ray diffraction shows that for a series of films prepared at 900 \ifmmode^\circ\else\textdegree\fi{}C, ${\mathrm{B}}_{\mathit{x}}$${\mathrm{C}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$ becomes more graphitic (with less turbostratic disorder) as x increases. There is a discontinuity between x=0.12 and x=0.15 in the variation of the distance between boron-carbon layers, as measured by the (002) plane spacing, which suggests the formation of an ordered ${\mathrm{BC}}_{5}$ compound. Using synchrotron radiation, we measured the near-edge x-ray absorption of these films at the boron and carbon 1s edges as a function of the angle between the photon beam and the substrate. The dependence of the absorption with angle at both edges shows the same behavior as that reported for highly oriented pyrolytic graphite, where transitions to unoccupied \ensuremath{\pi} bands are suppressed when the photon beam is normal to the graphite layers, proving that the boron substitutionally replaces carbon in these materials.
MACHINABLE CALCIUM PHOSPHATE CERAMICS (2002)

SiO2-free calcium phosphate ceramics with easy machinability were prepared by crystallization of the glasses in the CaO-P2O5-TiO2-Na2O system. β-Ca2P2O7- and β-Ca3(PO4)2-containing glass-ceramic, which was prepared by sintering of a compact of 6OCaO-30P2O5-3TiO2-7Na2O (in mol%) glass powders at 850°C, was found to show good machinability, as confirmed by a drilling test using a conventional carbide tool. SEM observation of the glass-ceramic showed that β-Ca2P2O7 crystals having a layered morphology are interlocking one another; plate-like crystals of several tens nanometers in thickness are piled up. The easy machinability of the glass-ceramics was suggested to result from the cleavage of β-Ca2P2O7 crystals precipitated in the glass. By volume-crystallization of a 43CaO-30P2O5-25TiO2-2Na2O glass, the glass-ceramic containing β-Ca2P2O7 and (Cao.5, Na)Ti2(PO4)3 crystals was found to be prepared. The glass-ceramic also could be drilled using a conventional carbide tool. These glass-ceramics in the present work have relatively high strength of ~120 MPa in bending.
Motor conduction block and high titres of anti-GM1 ganglioside antibodies: pathological evidence of a motor neuropathy in a patient with lower motor neuron syndrome. (1993)

A patient with a progressive lower motor neuron syndrome and neurophysiological evidence of motor axon loss, multifocal proximal motor nerve conduction block, and high titres of anti-ganglioside GM1 antibodies. Neuropathological findings included a predominantly proximal motor radiculoneuropathy with multifocal IgG and IgM deposits on nerve fibres associated with a loss of spinal motor neurons. These findings support an autoimmune origin of this lower motor neuron syndrome with retrograde degeneration of spinal motor neurons and severe neurogenic muscular atrophy.
Efficient homogeneous photochemical water gas shift reaction catalysed under extremely mild conditions by novel iridium(III) complexes: [(η5-Me5C5)Ir(bpy)Cl]+, [(η5-Me5C5)Ir(bpy)H]+, and [(η5-Me5C5)Ir(phen)Cl]+(bpy = 2,2′-bipyridine; phen = 1,10-phenanthroline) (1988)

The title compounds are shown to be active catalysts for the light-driven water gas shift reaction with turnover numbers up to 10 h–1; the iridium hydride species exhibits strong luminescence in solution at room temperature.
Attenuation Coefficients of Various Body Tissues, Fluids, and Lesions at Photon Energies of 18 to 136 keV (1975)

Radioactive sources of 241Am, 125I, 153Gd, 170Tm, and 57Co were used to measure the attenuation coefficient muL of various body tissues (gray and white matter, fat, liver, pancreas, and muscle), fluids (water, cerebrospinal fluid, plasma, and red blood cells), and cerebral lesions (blood clots, edematous brain tissue, and eight types of brain tumors) at 16 different energies in the range 18-136 keV. Experimental accuracy was about 0.1-0.3% and 0.2-0.4% in the energy ranges 18-60 keV and 60-136 keV, respectively. Comparisons with values determined in vivo and in vitro with an EMI scanner showed excellent agreement. It is hoped that these findings will provide a better understanding of the photon interactions at the sensitivity level of computed tomography.
Controlled release of perfumery alcohols by alkaline hydrolysis of 2-formyl- and 2-acetylbenzoates and their corresponding phthalides (2001)

The 2-formyl- and 2-acetylbenzoates of fragrance alcohols and their corresponding pseudo-esters (phthalides) are suitable precursors for the controlled release of fragrances by alkaline hydrolysis; the rate of benzoate hydrolysis depends on the structure of the alcohol released.
Moth-Like Chemo-Source Localization and Classification on an Indoor Autonomous Robot (2011)

Olfaction is a crucial sense for many living organisms. Many animals, especially insects, rely heavily on the olfactory sense for encoding and processing different chemical cues in order to perform several tasks such as foraging, predator avoidance, mate finding, communication etc.(22). Yet, olfaction has not been as widely studied as vision or the auditory system in insects. At the same time, robotic platforms capable of searching, locating and classifying odor sources in wind turbulence and in the presence of complex odors have diverse applications ranging from environmental monitoring (21), detection of explosives and other hazardous substances (19), land mine detection (2) to human search and rescue operations. The main challenge thereby is the stable and fast coding and decoding of odors and the localization of the sources (17). In our own recent work, we have proposed an insect-like mapless navigation mechanism which integrates surge-and-cast chemo search, path integration, wind detection and visual landmark navigation on an indoor mobile robot (28). Also, we have proposed a model based on insect navigation that is capable of navigating in highly dynamic environments and our model was compared directly to ant navigational data, with strikingly similar navigational behaviors (26). The problem of ambiguous information, particularly in the navigational context, is also addressed in our recent work (27). Beyond that, we have contributed significantly to modeling insect navigation and designing robotic systems such as: a model of the locust Lobula Giant Movement Detector (LGMD) tested on a high speed robot (29), moth-like odor localization for robots (30), control of an unmanned aerial vehicle using a neuronal model of a fly-locust brain (31; 32), moth-like optomotor anemotactic chemical search for robots (33), and a blimp flight control using a biologically inspired flight control system (34). Despite these advances, several biological systems with relatively simple nervous systems solve the odor localization and classification problem much more efficiently than their artificial counterparts: bees use odor to localize nests, ants use pheromone trails to organize foraging in swarms, lobsters use odor to locate food, the Escherichia bacteria use odors to locate nutrients, male moths use olfaction to locate female mates etc. The odor localization
On the existence of typical minimum distance for protograph-based LDPC codes (2010)

In this paper we prove that, for a certain class of protograph-based LDPC codes with degree-two variable nodes, a typical minimum distance exists. We obtain a tight bound on the sum of weight enumerators, up to some weight d*, for the ensemble of finite-length protograph LDPC codes. Then we prove that this sum goes to zero as the block length goes to infinity. Finally, we prove that Pr(d < d*) goes to zero as the block length goes to infinity. This typical minimum distance exists if degree-two nodes have certain connections to the check nodes. This is also important in practice since it identifies a certain class of protograph LDPC codes that have typical minimum distances.
Low-noise terahertz material parameter extraction using a spinning wheel (2009)

We demonstrate measurement of material optical parameters, in the THz regime, by mounting the sample under test on a spinning wheel. The proposed measurement technique is implemented using double-modulated terahertz differential timedomain spectroscopy (double-modulated THz-DTDS). Spinning sample addresses fundamental limitations imposed by linear sample dithering. The concept of spinning the sample allows rapid switching between the reference and sample signals with a single mechanical delay scan. We validate this technique by measuring the dielectric properties of thick polymer material.
A novel peptide-based vaccine candidate with protective efficacy against influenza A in a mouse model (2017)

Current influenza vaccines mainly induce antibody responses to the variable hemagglutinin proteins of the virus strains included in the vaccine. Instead, a broadly protective influenza vaccine should aim at inducing antibody- and/or cell-mediated immunity against conserved viral proteins. Vacc-FLU is a peptide based vaccine combining conserved B and T cell epitopes. Peptide selection was done using a proprietary peptide design platform technology focusing on responses to human leukocyte antigen (HLA)-restricted epitopes. Immunization of wild-type mice and mice transgenic for HLA-A2.1 with the peptide mix successfully induced both humoral and cell mediated immune responses. Partial protection from severe weight loss upon challenge was observed in both mouse strains but was stronger and observed at lower vaccine doses in transgenic mice. Our results show that the Vacc-FLU peptide mix is capable of inducing IFNγ-producing T cells and antibody-producing B cells which can protect from severe disease symptoms upon infection.
Post-translational Down-regulation of Melanoma Antigen-A11 (MAGE-A11) by Human p14-ARF Tumor Suppressor (2020)

X-linked primate-specific melanoma antigen-A11 (MAGE-A11) is a human androgen receptor (AR) coactivator and proto-oncogene expressed at low levels in normal human reproductive tract tissues and at higher levels in castration-resistant prostate cancer where it is required for androgen-dependent cell growth. In this report, we show that MAGE-A11 is targeted for degradation by human p14-ARF, a tumor suppressor expressed from an alternative reading frame of the p16 cyclin-dependent kinase inhibitor INK4a/ARF gene. MAGE-A11 degradation by the proteasome was mediated by an interaction with p14-ARF and was independent of lysine ubiquitination. A dose-dependent inverse relationship between MAGE-A11 and p14-ARF correlated with p14-ARF inhibition of the MAGE-A11-induced increase in androgen-dependent AR transcriptional activity and constitutive activity of a splice variant-like AR. Reciprocal stabilization between MAGE-A11 and AR did not protect against degradation promoted by p14-ARF. p14-ARF prevented MAGE-A11 interaction with the E2F1 oncoprotein and inhibited the MAGE-A11-induced increase in E2F1 transcriptional activity. Post-translational down-regulation of MAGE-A11 promoted by p14-ARF was independent of HDM2, the human homologue of mouse double minute 2, an E3 ubiquitin ligase inhibited by p14-ARF. However, MAGE-A11 had a stabilizing effect on HDM2 in the absence or presence of p14-ARF and cooperated with HDM2 to increase E2F1 transcriptional activity in the absence of p14-ARF. We conclude that degradation of MAGE-A11 promoted by the human p14-ARF tumor suppressor contributes to low levels of MAGE-A11 in nontransformed cells and that higher levels of MAGE-A11 associated with low p14-ARF increase AR and E2F1 transcriptional activity and promote the development of castration-resistant prostate cancer.
Effect of Chloroquine on the Formation of Tight Junctions in Cultured Immature Rat Sertoli Cells (1996)

Adjoining immature Sertoli cells in the seminiferous epithelium form a tight junctional complex leading to the development of the blood-testis barrier. Protease and antiprotease activities have been implicated in the process of formation of tight junctions. Here, we report the effect of chloroquine, an antimalarial drug with antiprotease activity, on the development of intercellular tight junctions in cultured immature rat Sertoli cells. For positive control, the classical lysosomotropic agent ammonium chloride was used. Sertoli cells were seeded in serum-free defined medium at a density of 3 x 10(6) cells/0.64-cm2 well on Matrigel-covered Millicell-HA filters. Chloroquine at concentrations ranging from 25 to 100 microM was added to the outer chamber of the bicameral system on either day 1 or 7 of the culture. The formation of the tight junction was monitored by the measurement of the transepithelial resistance (TER) at 24-hour intervals using an impedance meter. TER in untreated controls was 50 ohms/cm2 on day 1; it increased progressively to 80 ohms/cm2 by day 7 and plateaued until day 12. The cells treated from day 1 with chloroquine also showed a dose-dependent progressive increase in TER until day 9, reaching 225 ohms/cm2 in cells treated with the 100 microM concentration. In comparison to controls, the increase in TER was significantly higher. In cells treated with chloroquine starting from day 7 of culture onwards, there was no observable difference in TER from the untreated control. These observations demonstrate that chloroquine and ammonium chloride increase the TER of immature Sertoli cells in the bicameral chamber.
Modulation of Visual Responses in Macaque Frontal Eye Field during Covert Tracking of Invisible Targets (2006)

The purpose of this study was to investigate the interaction between internal representations of invisible moving targets and visual responses of neurons in frontal eye fields (FEFs). Monkeys were trained to make saccades to the extrapolated position of a target that was temporarily rendered invisible for variable durations as if it had passed behind an occluder. Flashed, task-irrelevant visual probe stimuli were used to study the visual responsiveness of FEF neurons during this task. Probes were flashed at various times and locations during the occlusion interval. Net changes in neuronal activity were obtained by comparing the activity on trials with probes with randomly interleaved trials without any probe. Most neurons showed an increase in firing rate in response to the probe, but some showed a decrease. Both types of responses were enhanced when the invisible target moved toward the receptive field (RF) as compared with trials on which the target moved away from the RF. Some neurons showed a spatial shift in the visual response during the occlusion interval. For cells that were excited by the probe, the shift tended to be correlated with the direction of motion of the target, whereas for cells that were inhibited the shift tended to be in the opposite direction. These results suggest that the role of FEF in predicting invisible target motion includes a sensory/perceptual component.
The Metabolite GnRH-(1-5) Inhibits the Migration of Immortalized GnRH Neurons (2013)

The decapeptide GnRH is an important regulator of reproductive behavior and function. In the extracellular matrix, GnRH is metabolized by the endopeptidase EC3.4.24.15 (EP24.15) to generate the pentapeptide GnRH-(1-5). In addition to its expression in the adult hypothalamus, EP24.15 is expressed along the migratory path of GnRH-expressing neurons during development. Although we have previously demonstrated a role for EP24.15 in the generation of the biologically active pentapeptide GnRH-(1-5) in regulating GnRH expression and mediating sexual behavior during adulthood in rodents, the modulatory role of GnRH-(1-5) in the migration of GnRH neurons during development remains unknown. To address this information gap, we examined the effect of GnRH-(1-5) on the cellular migration of a premigratory GnRH-secreting neuronal cell line, the GN11 cell, using a wound-healing assay. Dose- and time-response studies demonstrated that GnRH-(1-5) significantly delayed wound closure. We then sought to identify the mechanism by which GnRH-(1-5) inhibits migration. Because the cognate GnRH receptor is a G protein-coupled receptor, we examined whether GnRH-(1-5) regulates migration by also activating a G protein-coupled receptor. Using a high-throughput β-arrestin recruitment assay, we identified an orphan G protein-coupled receptor (GPR173) that was specifically activated by GnRH-(1-5). Interestingly, small interfering RNA to GPR173 reversed the GnRH-(1-5)-mediated inhibition on migration of GN11 neurons. Furthermore, we also demonstrate that the GnRH-(1-5)-activated GPR173-dependent signal transduction pathway involves the activation of the signal transducer and activator of transcription 3 in GnRH migration. These findings indicate a potential regulatory role for GnRH-(1-5) in GnRH neuronal migration during development.
