Supervision language control of electromechanical drives (2004)

The aim of this paper is to introduce a formal language based approach to the automatic supervision control of electromechanical drives. Modern applications often involve electromechanical drives with high dynamical complexity. The proliferation of these systems promises improved efficiency and reliability, reduced maintenance and operative costs, and a more environment friendly operation. However, they exhibit considerable complexities related with their behavior such as large uncertainties at a structural and parameter levels, multidimensionality, and strong mutual interactions. The integration of these systems with information processing techniques allows a better adaptive modeling of their behavior and thus better supervision concepts. Formal language techniques have been used in the past to study autonomous dynamical systems. Assuming the drive system as linguistic source, producing a certain language, the modeling framework is based on a formulation in terms of context-dependent grammars, distinguishing between information generated by the system and by the input control. Making use of the formal language descriptive characteristics the grammatical supervision algorithm governs the overall behavior of the drive. The formalism of the formal language based supervision control algorithm is presented and experimental results are discussed.
Diagnosis of EMI to laptop WWAN device from TFT-LCD driver using non-contact measurement-based transfer function technique (2010)

This paper presents a novel non-contact measurement technique for electromagnetic interference (EMI) diagnosis. The proposed technique uses vector network analyzer with antenna and near-field probes to measure the transfer function for an EMI path without interrupting the operation of device under test. As an example, with the help of the measured transfer function and equivalent source in the proposed technique, the EMI to laptop wireless wide area network (WWAN) device caused by a thin film transistor-liquid crystal display (TFT-LCD) driver is accurately diagnosed and appropriately treated. In addition, an easy-to-follow procedure is given for applying the presented non-contact measurement technique to the demonstrated example.
A review of the biochemical and neuropharmacological actions of lithium (1987)

The pharmacological actions central to the therapeutic effects of lithium have not yet been established, despite almost 40 years of clinical use and scientific investigation. We review the biochemical and neuropharmacological data relating to this problem and attempt to identify profitable areas for further research.
Internet of Things (2020)

The Internet of Things (IoT) which is also known as Web 3.0, represents the interconnection between the internet and objects, places and physical environments. IoT has some challenges in security: in fact, the problem exceeds largely data theft. For example, stopping the operation of a factory or causing material or human damage to it, opening the doors of a house or a store to make thefts, remote control of flying vehicle, blocking road traffic of an entire city, etc.
Segmentation of Rat Cardiac Ultrasound Images with Large Dropout Regions (2006)

Short-axis rat cardiac ultrasound images contain especially large regions of dropout which make it very difficult to segment the endocardium. Previous strategies, such as using shape priors, are not effective with such large dropout regions. This paper proposes a dropout modeling strategy, which can bridge large dropout regions and segment the endocardium when used along with shape priors. The segmentation is formulated as an active contour in a Maximum-APosteriori (M.A.P.) framework with explicit priors for the dropout function and shape. Further, the active contour is evolved by a strategy called tunneling descent. Tunneling descent is a deterministic evolution strategy which can escape from local minima. The combination of dropout modeling and tunneling descent gives active contours which can successfully segment rat cardiac ultrasound images. Experimental results comparing the performance of the new algorithm with manual segmentation and classical active contours are provided.
Plasma Spraying of Porous Electrodes for a Planar Solid Oxide Fuel Cell (1991)

Porous electrodes of Sr‐doped lanthanum manganite in a planar solid oxide fuel cell were made by the plasma spray technique. Spherical carbon particles were utilized as an effective pore former. Spraying a mixture of annealed oxide powders sized between 50 to 200 μm and 15 wt% solid Carbospheres resulted in a uniform coating of 40% porosity. Porous coatings were also obtained when rigid resin intermediates were sprayed followed by annealing at 1000°C in air.
Electrode Kinetics of Vanadium Flow Batteries: Contrasting Responses of V<sup>II</sup>-V<sup>III</sup>and V<sup>IV</sup>-V<sup>V</sup>to Electrochemical Pretreatment of Carbon (2015)

Electrochemical impedance spectroscopy and cyclic voltammetry were used to investigate the electrode kinetics of VII-VIII and VIV-VV in H2SO4 on glassy carbon, carbon paper, carbon xerogel, and carbon fibers. It was shown that, for all carbon materials investigated, the kinetics of VII-VIII is enhanced by anodic, and inhibited by cathodic, treatment of the electrode; in contrast, the kinetics of VIV-VV is inhibited by anodic, and enhanced by cathodic, treatment. The potential region for each of these effects varied only slightly with carbon material. Rate constants were always greater for VIV-VV than for VII-VIII except when anodized electrodes were compared, which may explain discrepancies in the literature. The observed effects are attributed to oxygen-containing functional-groups on the electrode surface. The considerable differences between the potentials at which enhancement of VII-VIII and inhibition of VIV-VV occur indicates that they do not correspond to a common oxidized state of the electrode. Likewise inhibition of VII-VIII and enhancement of VIV-VV do not correspond to a common reduced state of the electrode. It is possible that enhancement of both VII-VIII and VIV-VV is due to the same (active) state of the electrode.
Episodic Control as Meta-Reinforcement Learning (2018)

Abstract Recent research has placed episodic reinforcement learning (RL) alongside model-free and model-based RL on the list of processes centrally involved in human reward-based learning. In the present work, we extend the unified account of model-free and model-based RL developed by Wang et al. (2018) to further integrate episodic learning. In this account, a generic model-free “meta-learner” learns to deploy and coordinate among all of these learning algorithms. The meta-learner learns through brief encounters with many novel tasks, so that it learns to learn about new tasks. We show that when equipped with an episodic memory system inspired by theories of reinstatement and gating, the meta-learner learns to use the episodic and model-based learning algorithms observed in humans in a task designed to dissociate among the influences of various learning strategies. We discuss implications and predictions of the model.
Multiprocessors with a serial multiport memory and a pseudo crossbar of serial links used s a processor-memeory switch (1989)

This paper presents an inventive information exchange pro-cess between the main memory and cache equipped processors. It makes use of serial multiport memories and high throughput serial transmission supports. It is then possible to consider the realization of a multiprocessor with a common memory shared by several hundreds processors set with a performance level close to that of a crossbar network one's without having its disadvantages. This exchange process generates a family of possible architectures in which serial transfers of informations are parallelized, in the contrary of conventional architectures which serialize parallel transfers of informations.
Effects of Oral Supplementation of Glutamine on Small Intestinal Mucosal Mass Following Resection (1992)

Following massive small bowel resection, the remaining small bowel increases in mucosal weight, protein, deoxyribonucleic acid (DNA) content and absorptive function. Enteral nutrients are known to be important in stimulating this response. Recently, glutamine has been described as an essential fuel for the small intestinal mucosa and is thought to be trophic to the small bowel. We investigated if glutamine, when added to the diet in large quantities, might stimulate mucosal adaptation beyond that which normally occurs following physiologic feedings. Male Sprague-Dawley rats were placed on powdered rat chow supplemented with either 5% glutamine, 5% glycine or 5% glucose. After 4 days rats underwent 70% jejunoileal resection. Fourteen days after resection, protein, DNA and sucrase activity in the duodenum of the glutaminefed animals were all significantly lower than results from both the glycine and glucose groups. Duodenal mucosal weight was lower in the glutamine group than in the glycine group. In the ileum, DNA content was significantly lower for the glutamine group than the glycine group. These results suggest that high concentrations of glutamine in the diet can have negative effects on intestinal adaptation.
More Oil Using Downhole Water-Sink Technology: A Feasibility Study (2000)

Summary In this paper we report on recent R&D progress in downhole water sink (DWS) technology resulting in the establishment of a joint industry/Louisiana State U. (LSU) project-DWS Initiative. Presented are recent case histories of DWS design and successful field trials. The results are then analyzed comparatively in view of the superiority of DWS over single conventional completions. The analysis shows that, although DWS increases production of oil, its potential for reducing production of water is unknown and remains a controversial issue among operators. The case history analysis is followed by results from the authors' theoretical and experimental study on water-cut (WC) suppression with DWS. The study was performed by comparing WC development in single (conventional) and dual (DWS) well completions for a broad range of oil reservoirs with bottom water columns. These theoretical results are supported with experiments conducted using a laboratory physical model of a dual/single completed well-reservoir system. The results included in this paper demonstrate the persistence and irreversible nature of water cut in conventional wells compared to its flexibility and easy control in DWS completions. Defined is the range of production rates where DWS may give a sizable, up to 40%, reduction of WC. It is also shown, with calculations, how to determine the expected WC reduction for a given reservoir and well-completion design.

Induction of Tissue Factor Expression in Human Endothelial Cells by CD40 Ligand Is Mediated via Activator Protein 1, Nuclear Factor κB, and Egr-1 (2002)

Induction of tissue factor expression in endothelial cells via ligation of CD40 probably figures prominently in the pathogenesis of prevalent inflammatory diseases, including atherosclerosis. However, the molecular mechanisms of tissue factor gene expression triggered by CD40 ligand (CD40L) in this cell type remain unknown. We demonstrate here that the tissue factor promoter region -278 bp to +121 bp contains the CD40L-responsive elements, consisting of activator protein 1 (AP-1)+/-, nuclear factor (NF) kappaB-, and Egr-1-binding sites. Mutations of either the AP-1- or NF-kappaB-binding sites markedly reduced the CD40L-dependent promoter activation. The AP-1 and NF-kappaB sites displayed constitutive and CD40L-enhanceable DNA binding activity, respectively. Of note, mutation of the Egr-1-binding sites, previously not associated with CD40 signaling, impaired activation of the tissue factor promoter. Accordingly, CD40L strongly induced Egr-1 protein expression and DNA binding activity to all three bindings sites. In contrast to CD40L, other established inducers of tissue factor in endothelial cells, interleukin-1beta or tumor necrosis factor alpha, did not increase the expression of Egr-1. In conclusion, induction of tissue factor gene expression in human endothelial cells by CD40L involves AP-1 and NF-kappaB as well as Egr-1, a pathway previously not implicated in CD40 signaling and distinct from that employed by certain other proinflammatory cytokines.
Computing the Approximate Convex Hull in High Dimensions (2016)

In this paper, an effective method with time complexity of $\mathcal{O}(K^{3/2}N^2\log \frac{K}{ε_0})$ is introduced to find an approximation of the convex hull for $N$ points in dimension $n$, where $K$ is close to the number of vertices of the approximation. Since the time complexity is independent of dimension, this method is highly suitable for the data in high dimensions. Utilizing a greedy approach, the proposed method attempts to find the best approximate convex hull for a given number of vertices. The approximate convex hull can be a helpful substitute for the exact convex hull for on-line processes and applications that have a favorable trade off between accuracy and parsimony.
The pH of Commonly used Topical Ear Drops in the Treatment of Otitis Externa (2011)

Healthy ear canal skin has an acidic pH. Evidence suggests that reacidification of the ear canal may lead to resolution of otitis externa. The pH of 15 commonly prescribed topical ear drop preparations used in the treatment of otitis externa was measured using a Jenway 3020 pH meter with temperature compensation at 37.5°C. The pH values ranged from 2.89 to 7.83. Two-thirds of preparations tested were of acidic pH. The remaining one-third were alkaline. Reacidification of the ear canal may help in the treatment of otitis externa.
Sex pheromone of a coccoid insect with sexual and asexual lineages: fate of an ancestrally essential sexual signal in parthenogenetic females (2017)

Sex pheromones play a central role in intersexual communication for reproduction in many organisms. Particularly in insects, reproductive isolation that leads to speciation is often achieved by shifts of pheromone chemistries. However, the divergence and evolution of pheromones remain largely unknown. This study reveals a unique evolutionary consequence for terpenoid pheromones in coccoid insects. Coccoids, such as mealybugs, show clear sexual dimorphism: males are dwarf and short-lived, whereas females are wingless and almost immobile. Female pheromones are therefore indispensable for males to navigate for sexual reproduction, but some females can reproduce asexually. Interestingly, a derived asexual lineage that reproduces by parthenogenesis coexists with its ancestral lineage that reproduces sexually in a population of the pineapple mealybug, <i>Dysmicoccus brevipes</i> Here, we isolated, characterized and synthesized a novel monoterpene, (-)-(<i>anti</i>-1,2-dimethyl-3-methylenecyclopentyl)acetaldehyde, as a pheromone of the sexual females of <i>D</i><i>brevipes</i> This monoterpene aldehyde, with an irregular linkage of isoprene units, is notable, because all mealybug pheromones previously reported are carboxylic esters of terpenols. This compound was, however, never produced by the asexual females. As a consequence of acquiring parthenogenetic reproduction, the asexual females appear to have abandoned the production of the sex pheromone, which had been essential to attracting males in their ancestors.
Adaptive audio-aware scheduling in Xen virtual environment (2010)

With the development of client virtualization technology, it has become an important tendency to apply soft real-time applications in virtual environment. Currently, most schedulers in VMM (i.e., virtual machine monitor) take the fairly sharing of processor resources and load balancing as a main concern, while show less regard to application diversity and I/O responsiveness. This would be unable to meet the requirement for latency-sensitive tasks, such as audio application. Audio stream may suffer from severe input buffer overrun or output buffer underrun, especially in the case that there is no real-time guarantee on virtualized clients under heavy load. In this paper, we introduce experiments to illustrate that current scheduler in Xen does a poor job in guaranteeing fluent audio playing, and then formulate the fluent playing conditions a scheduler should satisfy. A scheduling strategy with soft real-time support is proposed to improve the responsiveness of latency-sensitive guests. To implement our proposition, we extend the Credit scheduler by using flexible time slice and real-time priority. Our solution is audio-aware and capable of adjusting the real-time priority of guest domains adaptively, achieving a better experience for end-users. The experimental results show that audio glitches can be completely eliminated via our extended scheduler even when the system load is very high.
Deriving logic systems for path delay test generation (1998)

We present an algorithm to derive logic systems for various classes of path delay test problems. In these logic systems, the value of a signal represents the relevant conditions that occur during a set of consecutively applied vectors. Starting from a set of basic values for valid signals at primary inputs, a state transition graph is constructed to enumerate all possible signal states relevant to path activation that are reachable by Boolean operations. These states include all incompletely specified states, composed as combinations of basic values. A distinguishability analysis then finds all state-pairs that need to be distinguished during test generation. The final step minimizes the number of states. For forward and backward implications of test generation in combinational or sequential circuits, the procedure provides optimal logic systems. We define optimality as the smallest set of logic states that provides the least possible ambiguity in implications. Thus, an optimal set of logic states will minimize the number of backtracks in test generation. A 10-valued logic described in the literature is found to be optimal for generating tests for single path delay faults. Other problems addressed in this paper include compact test generation through activation of many single path delay faults, test generation for rated-clock test application, and test generation for multiple path delay faults. The limitations and capabilities of various logic systems are illustrated by examples.
Tight-binding approach to the orbital magnetic moment and magnetocrystalline anisotropy of transition-metal monolayers (1989)

A perturbative theory of magnetocrystalline anisotropy and orbital moment in itinerant ferromagnets is presented that clearly outlines the close connection between these two quantities. The theory is used to study the magnetocrystalline anisotropy in transition-metal monolayers. The importance of the crystal-field energy and of the filling of the valence band is emphasized. For the first time the orbital contribution to the magnetization in monolayers is estimated; it is shown that it may produce an anisotropy in the magnetization of the order of 0.1\ensuremath{\mu}B per atom.
Energy Efficiency and Optimal Power Allocation in Virtual-MIMO Systems (2012)

This paper investigates energy efficiency (EE) performance of a virtual multiple-input multiple- output (MIMO) wireless system using the receiver- side cooperation with the compress-and-forward protocol. We derive a linear approximation of EE as a function of spectral efficiency (SE) in the low SE operation regime. In addition, we obtain a closed-form lower bound for EE which is valid for both low and high SE regions. This lower bound can be used for optimizing the power allocation between the transmitter and the relay in order to minimize the overall energy per bit consumption in the system. Both analytical and simulation results demonstrate that the virtual MIMO system using the receiver-side cooperation outperforms the multiple- input single-output (MISO) case in terms of energy efficiency. Finally we show that, with the optimal power allocation, the virtual-MIMO system achieves an EE performance close to that of an ideal MIMO system.
