Identification of genes involved in the susceptibility of Serratia marcescens to polyquaternium-1 (2004)

This study shows that random transposon mutagenesis is an effective tool for the elucidation of mechanisms of action and resistance to biocides. The results support our previous findings that PQ-1 is active against the cytoplasmic membrane of S. marcescens.
Carbothermal Reduction of Oxide Powder Prepared from Waste WC/Co Hardmetal by Solid Carbon (2005)

In the present study, the focus is on the analysis of carbothermal reduction of oxide powder prepared from waste WC/Co hardmetal by solid carbon under a stream of argon for the recycling of the WC/Co hard-metal. The oxide powder was prepared by the combination of the oxidation and crushing processes using the waste <TEX>$WC-8 wt.\%Co$</TEX> hardmetal as the raw material. This oxide powder was mixed with carbon black, and then this mixture was carbothermally reduced under a flowing argon atmosphere. The changes in the phase structure and gases discharge of the mixture during carbothermal reduction was analysed using XRD and gas analyzer. The oxide powder prepared from waste <TEX>$WC-8wt.\%Co$</TEX> hardmetal has a mixture of <TEX>$WO_{3} and CoWO_{4}$</TEX>. This oxide powder reduced at about <TEX>$850^{\circ}C$</TEX>, formed tungsten carbides at about <TEX>$950^{\circ}C$</TEX>, and then fully transformed to a mixed state of tungsten carbide (WC) and cobalt at about <TEX>$1100^{\circ}C$</TEX> by solid carbon under a stream of argon. The WC/Co composite powder synthesized at <TEX>$1000^{\circ}C$</TEX> for 6 hours from oxide powder of waste <TEX>$WC-8wt.\%Co$</TEX> hardmetal has an average particle size of <TEX>$0.3 {\mu}m$</TEX>.
Interventional calendar and protocol for cleft lift and palate repair at the maxillofacial and plastic surgery department of the Armand Trousseau Children’s Hospital (AP-HP, Paris) (2011)

Parents want their children’s’ faces, the most visible part of their bodies, one that marks their identity throughout life, to be perfect. To satisfy this understandably urgent desire, a high quality of primary treatment for cleft lip and palate is essential and must satisfy a double objective: restore normal morphology and normal function. The functional, morphological, and esthetic prognoses depend on the character of the defect, whether it stands alone or is associated in a syndrome with other malformations. Important sequellae flow from the quality of the initial repair, as a consequence of the surgery and other therapies as well as from the deformity itself.Before the year 2000, the Maxillo-facial and Plastic Surgery Service at the Armand Trousseau Hospital of the Pierre and Marie Curie Faculty of Medicine adhered to the protocol that Malek had described, making an initial repair of the soft palate at 3 months and then a cheiloplasty, with upper and lower triangles, and closure of the hard palate at 6 months. Since then we have adopted the more functional approach that Talmant described, integrating systematic nasal surgery and the type of lip surgery that Millard suggested without leaving any residual exposed bone after closure of the osseous cleft. We then perform gingivo-periosteal surgery with bone grafts on patients when they were between 4 and 6 years of age, after orthodontic therapy had been completed. This constitutes the last stage of primary treatment.The therapeutic approach we have been using on our service, which has evolved of over the last 20 years, has come to define its principal objective as integration of extensive rehabilitation into the very first stages of our multi-disciplinary therapy so as to minimize the establishment of faulty functioning of phonation, lip competence, and ventilation while avoiding any intervention that would have a harmful impact on facial growth. This multi-disciplinary approach, which integrates surgical evaluation and protocol, is indispensable and fully justifies treatment of patients with cleft lip and palate at accredited centers.
Definition of an Experimental Blood Like Fluid for Laser Measurements in Cardiovascular Studies (2007)

Abstract Nowadays it is necessary to perform experimental measurements to compare with numerical calculations. In this study we focus on different aqueous solutions which are tested to obtain in the same time a rheological blood like fluid and particular optical properties for laser measurements (particle image velocimetry (PIV) or laser Doppler velocimetry (LDV)). Using viscometric tests we show that the non Newtonian behavior of blood is reached by adding xanthan gum in aqueous glycerol and aqueous potassium thiocyanate solutions. Optical properties are directly achieved by modifying glycerol or thiocyanate potassium concentrations. Indeed we proove using refractometric measurements that the addition of xanthan gum does not affect the value of the refractive indexes. Finally, we can prepare an optical blood like fluid adapted to cardiovascular studies by adjusting the proportion of the different components.
Retinoid X Receptor (RXR) Agonist-Induced Activation of Dominant-Negative RXR-Retinoic Acid Receptor α403 Heterodimers Is Developmentally Regulated during Myeloid Differentiation (1999)

The multiple biologic activities of retinoic acid (RA) are mediated through RAR and retinoid X receptor (RXR) nuclear receptors that interact with specific DNA target sequences as heterodimers (RXR-RAR) or homodimers (RXR-RXR). RA receptor activation appears critical to regulating important aspects of hematopoiesis, since transducing a COOH-terminally truncated RARalpha exhibiting dominant-negative activity (RARalpha403) into normal mouse bone marrow generates hematopoietic growth factor-dependent cell lines frozen at the multipotent progenitor (EML) or committed promyelocyte (MPRO) stages. Nevertheless, relatively high, pharmacological concentrations of RA (1 to 10 microM) overcome these differentiation blocks and induce terminal granulocytic differentiation of the MPRO promyelocytes while potentiating interleukin-3 (IL-3)-induced commitment of EML cells to the granulocyte/monocyte lineage. In the present study, we utilized RXR- and RAR-specific agonists and antagonists to determine how RA overcomes the dominant-negative activity of the truncated RARalpha in these different myeloid developmental stages. Unexpectedly, we observed that an RXR-specific, rather than an RAR-specific, agonist induces terminal granulocytic differentiation of MPRO promyelocytes, and this differentiation is associated with activation of DNA response elements corresponding to RAR-RXR heterodimers rather than RXR-RXR homodimers. This RXR agonist activity is blocked by RAR-specific antagonists, suggesting extensive cross-talk between the partners of the RXR-RARalpha403 heterodimer. In contrast, in the more immature, multipotent EML cells we observed that this RXR-specific agonist is inactive either in potentiating IL-3-mediated commitment of EML cells to the granulocyte lineage or in transactivating RAR-RXR response elements. RA-triggered GALdbd-RARalpha hybrid activity in these cells indicates that the multipotent EML cells harbor substantial nuclear hormone receptor coactivator activity. However, the histone deacetylase (HDAC) inhibitor trichostatin A readily activates an RXR-RAR reporter construct in the multipotent EML cells but not in the committed MPRO promyelocytes, indicating that differences in HDAC-containing repressor complexes in these two closely related but distinct hematopoietic lineages might account for the differential activation of the RXR-RARalpha403 heterodimers that we observed at these different stages of myeloid development.
Speaking more like you (2008)

When people engage in conversation, they adapt the way they speak to the speaking style of their conversational partner in a variety of ways. For example, they may adopt a certain way of describing something based upon the way their conversational partner describes it, or adapt their pitch range or speaking rate to a conversational partner's. They may even align their turn-taking style or use of cue phrases to match their partner's. These types of entrainment have been shown to correlate with various measures of task success and dialogue naturalness. While there is considerable evidence for lexical entrainment from laboratory experiments, much less is known about other types of acoustic-prosodic and discourse-level entrainment and little work has been done to examine entrainments in multiple modalities for the same dialogue. We will discuss work on entrainment in multiple dimensions in the Columbia Games Corpus. Our goal is to understand how the different varieties of entrainment correlate with one another and to determine which types of entrainment will be both useful and feasible for Spoken Dialogue Systems.
Preferences of Coptotermes formosanus Shiraki and Coptotermes gestroi (Wasmann) (Blattodea: Rhinotermitidae) among Three Commercial Wood Species (2011)

The Formosan subterranean termite, Coptotermes formosanus Shiraki, and the Asian subterranean termite, Coptotermes gestroi (Wasmann), are both pests of wood in service in Hawaii and Florida. We conducted a laboratory study using method modified from those described in standard E1-09 of the American Wood Protection Association (AWPA 2009) to assess the termite resistance of three commercially available wood species used in regions of the USA where both termite species occur: Douglas fir, Pseudotsuga menziessii, southern yellow pine, Pinus spp. and redwood, Sequoia sempervirens. A multiple-choice (three-choice) assay was used for four weeks (28 days) in order to simulate field conditions of food choice and assess termite feeding preferences under 28 °C and 72-80% RH. 400 termites (360 workers: 40 soldiers) were released into each test jar. Five replicates and two controls of each wood species were used with each termite species. Termite mortality was recorded at the end of the test; and wood wafers were oven-dried and weighed before and after termite exposure to determine the mass loss due to termite feeding, and rated visually on a 0 (failure) to 10 (sound) scale. There were significant differences in mean mass loss values among the three wood species and between two termite species. The mean mass loss value for redwood was significantly lower than Douglas fir and southern yellow pine with both termite species. However, C. formosanus showed increased feeding on Douglas fir and southern yellow pine compared to C. gestroi.
Denial-of-Service Attacks on Dynamic Spectrum Access Networks (2008)

Cognitive radio technologies have emerged as a platform to solve the problem of spectrum scarcity for wireless applications since cognitive radios have the potential to utilize the idle licensed spectrum bands in an intelligent way without interfering with other licensed devices. However, most of the proposed protocols for opportunistic usage of the licensed spectrum bands assume that the participants involved in the protocols are honest and that there are no malicious adversaries that will attack the network. Using two examples, we demonstrate that in the presence of a malicious adversary the systems designed making these assumptions will fail to fulfill their goals of minimal disruption of the primary users and efficient utilization of the unused spectrum. We also briefly discuss some security design goals of the future cognitive DSA networks.
Scanning laser terahertz near-field imaging system (2012)

We have proposed and developed a scanning laser terahertz (THz) near-field imaging system using a 1.56 μm femtosecond fiber laser for high spatial resolution and high-speed measurement. To obtain the two-dimensional (2D) THz images of samples, the laser pulses are scanned over a 2D THz emitter plate [DASC: 4'-dimenthylamino-N-methyl-4- stilbazolium p-chlorobenzenesulfonate] by a galvano meter. In this system, THz wave pulses locally generated at the laser irradiation spots transmit through the sample set on the emitter, and the amplitude of the transmitted THz wave pulse is detected by using a typical THz time-domain spectroscopy (THz-TDS) technique. Using this system, we have succeeded in obtaining THz transmission images of a triangle shaped metal sheet of millimeter-size and a human hair sample with a spatial resolution of sub-wavelength order up to ~27 μm (~λTHz/28) at an imaging speed of about 47 seconds/image for 512 x 512 pixels.
flexLiTE: flexible micro-LED integrated optoelectrodes for long-term chronic deep-brain studies (2022)

Abstract Understanding complex neuronal circuitry and its functions of a living organism requires a specialized tool which is capable of recording a large ensemble of neuronal signals at single cell resolution and modulating neuronal activities selectively in the target region of brains with high spatiotemporal resolution, while sustaining long-term chronic operation without significant tissue degeneration or device shifts. We hereby present an ultra-flexible, minimally-invasive, Michigan-type neural probe for chronic opto-electrophysiology studies: flexLiTE (flexible micro-LED integrated optoelectrodes). flexLiTE incorporates monolithically integrated, soma-sized inorganic micro-LEDs (12 individually operated) and 32 recording electrodes. Both stimulation and recording modalities were achieved by stacking two modules on a flexible substrate: one with micro-LEDs for neuromodulation and the other with recording sites, resulting in a 115 μm-wide,12 μm-thick, 10 mm-long optoelectrode. From prototype devices, we demonstrated the reliable operation of flexLiTEs for recording and modulation of hippocampal neurons in a freely moving mice for over ∼8 month.
On the age of information in multi-source queueing models (2020)

Freshness of status update packets is essential for enabling services where a destination needs the most recent measurements of various sensors. In this paper, we study the information freshness of single-server multi-source queueing models under a first-come first-served (FCFS) serving policy. In the considered model, each source independently generates status update packets according to a Poisson process. The information freshness of the status updates of each source is evaluated by the average age of information (AoI). We derive an exact expression for the average AoI for the case with exponentially distributed service time, i.e., for a multi-source M/M/1 queueing model. Moreover, we derive three approximate expressions for the average AoI for a multi-source M/G/1 queueing model having a general service time distribution. Simulation results are provided to validate the derived exact average AoI expression, to assess the tightness of the proposed approximations, and to demonstrate the AoI behavior for different system parameters.
Up-Fusion (2014)

The amount of multimedia data on the Internet has increased exponentially in the past few decades and this trend is likely to continue. Multimedia content inherently has multiple information sources, therefore effective fusion methods are critical for data analysis and understanding. So far, most of the existing fusion methods are static with respect to time, making it difficult for them to handle the evolving multimedia content. To address this issue, in recent years, several evolving fusion methods were proposed, however, their requirements are difficult to meet, making them useful only in limited applications. In this article, we propose a novel evolving fusion method based on the online portfolio selection theory. The proposed method takes into account the correlation among different information sources and evolves the fusion model when new multimedia data is added. It performs effectively on both crisp and soft decisions without requiring additional context information. Extensive experiments on concept detection and human detection tasks over the TRECVID dataset and surveillance data have been conducted and significantly better performance has been obtained.

How many winning tickets are there in one DNN? (2020)

The recent lottery ticket hypothesis proposes that there is one sub-network that matches the accuracy of the original network when trained in isolation. We show that instead each network contains several winning tickets, even if the initial weights are fixed. The resulting winning sub-networks are not instances of the same network under weight space symmetry, and show no overlap or correlation significantly larger than expected by chance. If randomness during training is decreased, overlaps higher than chance occur, even if the networks are trained on different tasks. We conclude that there is rather a distribution over capable sub-networks, as opposed to a single winning ticket.

Evidence for an Inhibiting Influence of Fetal Bovine Serum on “Spontaneous” Neoplastic Transformation <italic>In Vitro</italic> (1972)

C3H mouse embryo cells grown in horse serum-supplemented, chemically defined medium were shown previously to undergo “spontaneous” neoplastic transformation early as compared with cells From the same cell pool grown in Fetal bovine serum supplement. These observations suggested that some component(s) of horse serum accelerates spontaneous neoplastic transformation, or that Fetal bovine serum inhibits neoplastic transformation, or that both phenomena occur. The present study supports the conclusion that fetal bovine serum does tend to inhibit spontaneous neoplastic transformation. These transformations were delayed or prevented in 4 independent sublines when Fetal bovine serum was added to a medium containing horse or calf serum in which transformations occurred early. In more limited tests with the fetuin fraction of fetal bovine serum, there appeared to be some inhibition of transformation, but the results were not conclusive.
Wavelength dependence of noise figure in InGaAs/InGaAsP multiple-quantum-well laser amplifier (1992)

Theoretical and experimental results are presented for the wavelength dependence of the noise figure and the single-pass gain in multiquantum well amplifiers. The theoretical model accounts for both conduction band/heavy hole band and conduction band/light-hole band transitions. The calculations are in good agreement with the experimental results, which indicate that the noise figure has some dependence on the wavelength. A minimum traveling-wave amplifier (TWA) noise figure of 3.9 dB has been measured at 1550 nm for a single-pass of 22 dB.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
CNS delivery of antisense oligodeoxynucleotides using biodegradable microspheres (2000)

Antisense oligodeoxynucleotides can selectively inhibit gene expression provided they are delivered to their target site successfully for a sufficient duration. Biodegradable microspheres have previously been developed for the potential systemic delivery of antisense oligodeoxynucleotides and offer an excellent strategy for central administration of antisense oligodeoxynucleotides, providing a sustained-release delivery system. Biodegradable microspheres were formulated to entrap antisense oligodeoxynucleotides for stereotaxic implantation into site-specific regions of the rat brain.Release profiles of antisense oligodeoxynucleotides from biodegradable microspheres over 56 days that were triphasic were observed with high molecular weight polymers. Antisense oligodeoxynucleotides loaded into microspheres (1-10μm) had a five-fold increase in cellular association with glial and neuronal cells compared to the naked molecule, which was partially due to a greater cellular accumulation as observed by a slower efflux profile. In vivo distribution studies of antisense oligodeoxynucleotides demonstrated that the use of microspheres provided a sustained-release over more than 2 days compared to 12 hours of the naked molecule. Efficacy of antisense oligodeoxynucleotides was demonstrated during locomotor activity investigations, which significantly reduced cocaine-induced locomotor activity, where no efficacy was demonstrated with microspheres, possibly attributed to antisense loading and measurements being taken during a lag phase of antisense oligodeoxynucleotide release. Biodegradable microspheres can be delivered site-specifically into the brain and provide sustained-release of antisense oligodeoxynucleotides, offering the potential of in vivo efficacy in these reagents in the brain.
Operation of a dielectric motor with a low conductivity liquid (1970)

Operation of a liquid immersed dielectric motor has been obtained with a dielectric medium whose conductivity was two orders lower than the previous reported limit.
Simulation of inhomogeneous broadening and mode-beating effects in semiconductor lasers (1988)

A model is proposed in which the conduction band is discretised into energy intervals corresponding to longitudinal-mode separations for the simulation of inhomogeneous broadening and mode beating effects in semiconductor lasers. Four first-order relaxation processes are proposed to take account of intraband relaxations, and mode beating is included as a separate nonlinear gain term in the rate equations. In addition to the usual results of spectral-hole burning, single longitudinal-mode stabilisation and increased damping of relaxation oscillations, the model also accounts for the excitation of nonadjacent longitudinal modes experimentally observed at high bias in narrow planar-stripe lasers and the temperature dependence of spectral behaviour in CSP lasers.
