Être intervenant auprès de parents ayant un trouble de personnalité limite en protection de la jeunesse : quand la souffrance de l’un se conjugue au désarroi de l’autre (2019)

Environ 22,5% des mères d’enfants pris en charge par les services de protection de la jeunesse présente un trouble de personnalité limite avéré ou probable. Il existe cependant très peu d’informations sur les défis que doivent relever les intervenants psychosociaux qui travaillent avec cette clientèle dans le contexte d’un mandat de protection. Cette étude qualitative s’est penchée sur cette problématique particulière. Les données ont été recueillies selon la méthode du groupe cible (focus group) auprès de 104 intervenants du Centre jeunesse de Montréal-Institut universitaire dans le cadre de six rencontres. Les résultats suggèrent que ceux-ci perçoivent que leurs interventions auprès de ces familles sont soumises à un ensemble de contingences qui rendent leur travail particulièrement complexe et exigeant. Trois thèmes principaux reliés aux préoccupations et aux difficultés à l’égard de leur pratique et de leurs besoins ont ainsi été mis en évidence. Le premier concerne les difficultés d’intervention liées au contexte interpersonnel. Les analyses révèlent notamment que devoir concilier protection des enfants et aide aux parents ou encore parler aux enfants du trouble mental de leur parent s’avèrent difficile pour eux. Le second thème, les enjeux liés au contexte environnemental, concernent leurs perceptions des contingences associées à l’organisation interne des services en centre jeunesse et à la collaboration avec les partenaires externes (milieu judiciaire et psychiatrie adulte). L’impact des contextes interpersonnel et environnemental sur les intervenants eux-mêmes constitue le troisième thème. Les analyses suggèrent que la prise en charge des familles touchées par ce trouble mental sollicite énormément les intervenants sur le plan affectif et cognitif et leur pose des défis cliniques quotidiens. Enfin, cet article souligne l’importance de se préoccuper des défis auxquels font face les intervenants oeuvrant auprès de familles touchées par un trouble de personnalité limite et présente quelques recommandations d’ordre organisationnel et clinique pour mieux les soutenir.
PRODUCTION OF MALONALDEHYDE FROM SQUALENE, A MAJOR SKIN SURFACE LIPID, DURING UV‐IRRADIATION (1989)

Malonaldehyde (MA), a product of lipid peroxidation, is known to have a number of toxicological effects. Among skin surface components, squalene has been suggested as a significant source of MA following UV exposure. Irradiation of squalene coated on the inside surface of glass tubes served as a simple model to examine skin surface photochemistry. Malonaldehyde produced during UV-irradiation was reacted with methyl hydrazine to form N-methylpyrazole, which was then measured by gas chromatographic analysis. Ultraviolet A-irradiation produced low levels of MA from squalene, with a maximum of 1.0 nmol MA/mumol squalene near 6 h. Malonaldehyde production varied with the energy of irradiation, with levels of 176 nmol/mg squalene and 9 nmol/mg squalene produced after 3 h of irradiation with UVB and UVA, respectively. The thiobarbituric acid (TBA) assay for lipid peroxidation showed large overestimations of MA levels under all irradiation conditions tested. The TBA assay predicted the highest levels of MA with UVC but we did not detect any MA with our assay.

A New Approach to the Estimation of Linear Driving Force Parameters in the Numerical Simulation of Pressure Swing Adsorption Process (2001)

A mass transfer model based on a linear driving force approximation is widely used in the numerical simulation of pressure swing adsorption processes. This approximation involves a proportionality constant that is dependent on the cycle time. Whereas graphical correlations have been given and curve fitting of experimental data has also been used for estimation of the proportionality constant, in the present study, a new approach based on time-dependent Sherwood number as used in the modeling of extraction processes is suggested for this estimation. PSA simulation model predictions using linear driving force parameters calculated by this approach are compared with experimental data on the separation of CO2/N2 mixtures with activated carbon as the adsorbent.
Trial for Enhancing Technical Writing Skills to Improve Training Efficiencyin Writing Technical Papers and Its Effectiveness Evaluation (2010)

One of the important undertakings of student in laboratory education practiced in higher educational institutions, such as universities, is the development of technical communication skills based on training in technical writing for preparing not only theses but also papers to be submitted to society journals. However, technical writing is difficult for students who study at a technical university. Moreover, it might become a burden for the teaching staff, when a teaching staff trains many students. With the background of this situation, we have examined four effective methods described in this paper from year 2006. This paper describes the effects of practicing our four methods on the basis of the answers to questionnaires provided by students in years 2006 and 2007.
Theory of Deep Learning III: explaining the non-overfitting puzzle (2017)

A main puzzle of deep networks revolves around the absence of overfitting despite large overparametrization and despite the large capacity demonstrated by zero training error on randomly labeled data. In this note, we show that the dynamics associated to gradient descent minimization of nonlinear networks is topologically equivalent, near the asymptotically stable minima of the empirical error, to linear gradient system in a quadratic potential with a degenerate (for square loss) or almost degenerate (for logistic or crossentropy loss) Hessian. The proposition depends on the qualitative theory of dynamical systems and is supported by numerical results. Our main propositions extend to deep nonlinear networks two properties of gradient descent for linear networks, that have been recently established (1) to be key to their generalization properties: 1. Gradient descent enforces a form of implicit regularization controlled by the number of iterations, and asymptotically converges to the minimum norm solution for appropriate initial conditions of gradient descent. This implies that there is usually an optimum early stopping that avoids overfitting of the loss. This property, valid for the square loss and many other loss functions, is relevant especially for regression. 2. For classification, the asymptotic convergence to the minimum norm solution implies convergence to the maximum margin solution which guarantees good classification error for "low noise" datasets. This property holds for loss functions such as the logistic and cross-entropy loss independently of the initial conditions. The robustness to overparametrization has suggestive implications for the robustness of the architecture of deep convolutional networks with respect to the curse of dimensionality.
Age-dependent growth rate of primary breast cancer (1993)

To observe a beneficial effect of screening, if any, for women younger than age 50 years, more frequent screening than in the older age group is necessary.
Modulation of glial glutamate transport through cell interactions with the extracellular matrix (2002)

Glial glutamate transport plays a pivotal role in maintaining glutamate homeostasis in the central nervous system. Expression of glutamate transporters is highly regulated during brain development, and a number of pathological conditions are associated with deficits in expression and/or function of glutamate transports. While several soluble factors have been shown to regulate the expression of glutamate transporter, the contribution of cell-cell interaction and cell-environmental interaction in the regulation of glutamate transport is unknown. Extracellular matrix (ECM) molecules are essential components in cell-cell and cell-environmental interactions, and the ECM has been shown to play critical role in normal development and during brain pathogenesis. We, therefore, investigated the possibility that ECM molecules may regulate astrocytic glutamate transport. Therefore, we cultured rat cortical astrocytes with different ECMs and determined expression levels of the two astrocytic glutamate transporters GLT-1 and GLAST by Western Blot and determined transporter activity through measurements of 3H-D-aspartate uptake. Astrocytes grown on poly-ornithine or poly-D/L-lysine showed approximately two-fold higher GLT-1 expression than sister cells grown on plastic dishes without ECM. Naturally occurring ECM's, including laminin and collagen, showed a dose-dependent regulation of GLT-1 protein expression. These effects were specific for GLT-1 as GLAST expression was unaffected by different ECMs. Surprisingly, however, none of the examined ECMs altered the apparent glutamate uptake activity. In probing blots side-by-side for expression of Na(+)/K(+)-ATPase, we found that ECMs affected expression of Na(+)/K(+)-ATPase and GLT-1 in a reciprocal fashion. Poly-ornithine, for example, enhanced GLT-1 expression, but reduced expression of Na(+)/K(+)-ATPase. Na(+) transport may, thus, be a limiting factor for glutamate uptake.
Military Spaceplane Flight Demonstration Concepts (2004)

*† ‡ This paper re views flight demonstration concepts prepared by and for the Air Force Research Laboratory’s Air Vehicle’s Directorate in support of the Space and Missile Systems Center and the Defense Advanced Research Projects Agency. The objective of these demonstrator s is to validate critical Military Spaceplane technologies and operations through early flight test. Demonstration vehicles range from small, lower cost vehicles focused strictly on validating technologies and operations concepts, to larger more expensive vehicles with significant residual capability. Aggressive military operability goals are a key feature of all the proposed flight demonstration concepts. The role of ground technology maturation programs versus flight demonstration is discussed, and a r oadmap to future capabilities presented.

Macrocycles. XXVIII. Cyclic poly(benzonitrile ether)s derived from bisphenol A (2003)

Abstract Bisphenol A was polycondensed with 2,6‐dichlorobenzonitrile, 2,6‐difluorobenzonitrile, 2,4‐difluorobenzonitrile, and 3,5‐difluorobenzonitrile in sulfolane. With 2,6‐and 2,4‐difluorobenzonitrile, quantitative conversions were achieved, and matrix‐assisted laser desorption/time‐of‐flight mass spectra revealed a nearly quantitative formation of cyclic oligoethers and polyethers. Furthermore, O,O ′‐bistrimethylsilyl bisphenol A was polycondensed with the aforementioned dihalobenzonitriles in dry N ‐methylpyrrolidone (promoted by potassium carbonate). Both the temperature and time were optimized. Only with 2,6‐difluorobenzonitrile were nearly quantitative conversions achieved, and this resulted in high molecular weights and high cycle contents. Size exclusion chromatography elution curves exhibited a tendency toward a bimodal character when larger fractions of cycles were present. Calibration with polystyrene standards indicated number‐average molecular weights of up to 10 5 Da and weight‐average molecular weights of up to 2.3 × 10 5 Da. © 2003 Wiley Periodicals, Inc.

Primary Retroperitoneal Mucinous Cystadenocarcinoma: A Case Report (2023)

Mucinous neoplasms are commonly seen in the ovaries and pancreas. Their occurrence in the retroperitoneum is uncommon. We present a case of a retroperitoneal mucinous cystadenocarcinoma in a 54-year-old female who presented with right flank pain. Imaging demonstrated an 8.6 × 7.9 cm mass at the anterior surface of the lower pole of the right kidney, suspicious for renal cell carcinoma. Serum tumor markers carbohydrate antigen 19-9 (CA 19-9) and cancer embryonic antigen (CEA) were within normal limits, and cancer antigen 125 (CA 125) was elevated. Surgical resection of the mass was performed. Intraoperatively, the mass was noted to lie in the retroperitoneum, unattached to the kidney. On gross examination, a 10.0 × 7.0 × 7.0 cm unilocular cystic structure with red-brown mucoid material was present. The inner lining was mostly smooth with areas of excrescences, covering less than 5% of the surface area. Microscopic examination showed cystic areas lined by mucinous epithelium with an underlying ovarian-type stroma. Solid areas showed features of a borderline papillary mucinous tumor with invasive carcinoma. A diagnosis of mucinous cystadenocarcinoma was made. Their occurrence in the retroperitoneum is unusual. Although rare, this entity should always be considered in the differential diagnosis of retroperitoneal cystic lesions.
Evidence of single domain switching in hafnium oxide based FeFETs: Enabler for multi-level FeFET memory cells (2015)

Recent discovery of ferroelectricity in HfO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> thin films paved the way for demonstration of ultra-scaled 28 nm Ferroelectric FETs (FeFET) as non-volatile memory (NVM) cells [1]. However, such small devices are inevitably sensible to the granularity of the polycrystalline gate oxide film. Here we report for the first time the evidence of single ferroelectric (FE) domain switching in such scaled devices. These properties are sensed in terms of abrupt threshold voltage (VT) shifts leading to stable intermediate VT levels. We emphasize that this feature enables multi-level cell (MLC) FeFETs and gives a new perspective on steep subthreshold devices based on ferroelectric HfO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> .
Turbulence energetics in an axisymmetric impinging jet flow (2019)

Turbulence energetics is investigated in the impingement and wall jet regions of an axisymmetric impinging jet flow, by using the two-dimensional particle-image velocimetry measurement technique. The inlet-based Reynolds number is equal to 5200, and the height to the diameter ratio is equal to 5.95. This study shows that turbulence kinetic energy balances in outer, middle, and inner layers of the impingement region differ greatly from each other. The balances in near-field and far-field wall jet regions differ, as well. This study also provides various useful insights into the directional characteristics of the energy transports. For example, it has revealed that the turbulence diffusion process transports energy in the upstream direction in the jet core, but obliquely in the mixing layers. The balance terms are decomposed into physically meaningful spatial components, which, among various other insights, show that the negative production rate that is earlier reported in the stagnation region is caused by the negative work contributions of the radial and the tangential Reynolds stresses. This study, overall, lets us have a thorough understanding of the turbulence production, the convection, the turbulence diffusion, and the viscous diffusion processes, while the turbulence dissipation and the pressure diffusion terms are clubbed together and obtained as the residual of the energy balance equation. Information that is extracted from the residual has demonstrated the failure of Lumley’s model to estimate the pressure diffusion rate near the impingement surface.
Macro and Molecular Level Insights on Gas Hydrate Growth in the Presence of Hofmeister Salts (2020)

The effect of few monovalent salts (NaCl, NH4Cl, and GdmCl) as additives, according to the Hofmeister series on the growth of methane gas hydrates, has been studied using experiments as well as molecular dynamics (MD) simulation. Further, the Hofmeister effects on hydrate crystallization have been correlated with the methanol as an additive, which is a known thermodynamic hydrate inhibitor for hydrate growth. One of the previous studies (discussed later in this article) available in the literature concludes that methane hydrate formation from ice might show enhanced kinetics in the presence of salts; this behavior is contrary to the general usage of such salts as hydrate inhibitors. This conclusion may not necessarily be true for experiments done with liquid water, and therefore, this work explores the behavior of these salts in a lab-scale setup. In addition, current work reports detailed MD simulation studies to gain insight into the mechanism of hydrate formation in the presence of Hofmeister series salts at two different concentrations of 1 and 10 wt % in water and compare the results with hydrate formation in the methanol–water system. Our study suggests that the presence of these additives at low concentrations (1 wt %) does enhance the hydrate growth kinetics. However, at higher concentrations (10 wt %), inhibition by these additives persisted, and prolonged nucleation, as well as retarded growth, was observed.
Network I/O Path Analysis in the Kernel-Based Virtual Machine Environment through Tracing (2009)

Virtualization is experiencing a resurgence of interest for diverse uses including server consolidation and shared hosting. Unfortunately, the overhead of virtual machine network I/O has became the main factor that affects the performance of the virtual machine. Meanwhile, few tools are currently available to help debug performance problems in virtual machine environments. Therefore, it is especially significant to analyze Virtual Machine network I/O path and then improve the performance. Firstly, we analyze the Kernel-based Virtual Machine (KVM) and its network I/O architecture. Then the tracing tool SystemTap and tracing technology in virtual machine are described. This paper presents in detail the ingressing path and the corresponding overhead in the environment of KVM through tracing. The bottlenecks that affect the performance of network virtualization in KVM are also summarized to make future optimizing work easier.

Time to Digital Converter Based on a Ring Oscillator with Even Number of Non-Inverting Elements (2018)

The proposed Time to Digital Converter architecture is based on a ring oscillator with an even number of delay units. The core system is able to convert time intervals ranging from 0.1 ns to 30 ns in a reduced silicon area of around 140×140 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> for 8 bit. The extension of the maximum time count can be performed by adding an higher-level counter. Moreover, each delay element of the converter can be evaluated by using a Built-In Self Test (BIST) procedure and calibrated in order to reduce process variability effects in each ring stage.
Using a new kind of organic complex system of electrical bistability for ultrahigh density data storage (1997)

We present a new kind of organic complex system of electrical bistability, m-nitrobenzal malononitrile and diamine benzene (mNBMN-DAB), which can be employed as ultrahigh density data storage devices by scanning tunneling microscopy (STM). The mNBMN-DAB thin film was prepared on highly oriented pyrolitic graphite (HOPG) substrates using physical vacuum deposition method. A critical voltage pulse between the STM tip and the surface of the HOPG substrate can make marks on the thin films. The size of the marks is about 1.3 nm and the corresponding data storage density is larger than 1013 bits/cm2. A new mechanism of the charge transfer in the system for the data storage is suggested. These results show a great potential of this type of organic composite systems in the application of the ultrahigh density data storage.
Volumetric Light-Field Excitation (2016)

We explain how to concentrate light simultaneously at multiple selected volumetric positions by means of a 4D illumination light field. First, to select target objects, a 4D imaging light field is captured. A light field mask is then computed automatically for this selection to avoid illumination of the remaining areas. With one-photon illumination, simultaneous generation of complex volumetric light patterns becomes possible. As a full light-field can be captured and projected simultaneously at the desired exposure and excitation times, short readout and lighting durations are supported.

Growth of spherical clusters of hydroxyapatite in gelatin which resemble deposits in biofilms (1991)

Gelatin gels were prepared which incorporated triammonium orthophosphate solution at pH 8.5—9.5. Hydroxyapatite was precipitated within these gels by covering their surfaces with calcium nitrate solution. When the hydroxyapatite within the surface layer was examined by scanning electron microscopy, it appeared as roughly spherical clusters with internal structure; this structure arises because the clusters were composed of plate‐like crystals. The clusters were closely similar to bodies in published electron micrographs of marine surfaces fouled by bacteria. They also resembled clusters of poorly crystalline hydroxyapatite formed on the surfaces of urinary catheters which encrust as a result of bacterial colonisation.
