Lexical Description of Signs — Linguistic Benefits of a Geometric Dependency Model Description lexicale des signes — Intérêts linguistiques d’un modèle géométrique à dépendances

Traitement Automatique des Langues , 2009,
Abstract: This article deals with formal representation of sign language lexicons. Present models are based on systematic parameter specification, which we think lacks flexibility. We suggest an adaptable model based on a sequential and geometric approach. Then we discuss a graphical representation for it that allows for a clearer view of the descriptions’ structures and dependencies. We give hints on the benefits we see in the model onto two different domains: sign language synthesis and data base driven studies of sign languages
Use of OVH residue in the ceramics industry
Filhol, A.,Blanc, J. J.,Navarro, S.,Grellier, S.

Abstract: Hydrothermal oxidation (OVH: “Oxydation par Voie Humide”) is an innovative technology used for waste water treatment, which is presented as an alternative to sewage sludge spreading and incineration. This process generates a fine-grain (D50 = 2 μm) mineral by-product, which is very useful for the ceramics industry due to its high content in argillaceous elements, quartz, phosphate and calcium carbonate. Therefore, this work describes the recycling of this OVH residue in the ceramics industry, and more particularly in the manufacture of calcareous earthenware wall tiles. The residue can be combined with a white calcareous earthenware body up to a level of 7% without significant colorimetric deterioration, and if this is raised to 15%, it is possible to completely replace the crushed chalk, some of the quartz and reduce costly imported tight-burning clays by 6%. The developed body exceeds standardised requirements (modulus of rupture: + 40%; moisture swelling and glaze quality), which means that a 20°C reduction in firing temperature might be envisaged. An industrial pilot test of 1500 kg conducted by the DESVRES site managers with 100 m2 of tiles (format: 15 x 20 cm) confirmed these laboratory results, in particular validating the absence of rheological disturbance of the slip and the harmlessness of the addition on the maturing glaze quality. Furthermore, the nature of the fumes emitted in the test complied with current regulations, and the finished product did not exceed the thresholds defined by European regulations for inert waste classification. La oxidación hidrotérmica (OVH: “Oxydation par Voie Humide” u oxidación por vía húmeda) es una tecnología innovadora usada en la depuración de las aguas residuales, que se presenta como alternativa al esparcimiento y a la incineración de los lodos de aguas negras. Este proceso genera un producto derivado de mineral de grano fino (D50 = 2 μm) que es muy útil para la industria cerámica debido a su elevado contenido en elementos arcillosos, cuarzo, fosfato, y carbonato de calcio. Por tanto, este trabajo proporciona una descripción del proceso de reciclaje de este residuo de OVH en la industria cerámica, y más concretamente en la fabricación de azulejos de pasta calcárea. Se puede combinar el residuo con una pasta de azulejo calcárea hasta un contenido del 7% sin que se produzca un deterioro colorimétrico significativo y, si se aumenta hasta el 15%, es posible sustituir por completo la caliza triturada, algo del cuarzo y, además, reducir el alto coste de las arcillas vitrificadas de importación en un 6%.

DSIR: Assessing the Design of Highly Potent siRNA by Testing a Set of Cancer-Relevant Target Genes
Odile Filhol,Delphine Ciais,Christian Lajaunie,Peggy Charbonnier,Nicolas Foveau,Jean-Philippe Vert,Yves Vandenbrouck
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0048057
Abstract: Chemically synthesized small interfering RNA (siRNA) is a widespread molecular tool used to knock down genes in mammalian cells. However, designing potent siRNA remains challenging. Among tools predicting siRNA efficacy, very few have been validated on endogenous targets in realistic experimental conditions. We previously described a tool to assist efficient siRNA design (DSIR, Designer of siRNA), which focuses on intrinsic features of the siRNA sequence. Here, we evaluated DSIR’s performance by systematically investigating the potency of the siRNA it designs to target ten cancer-related genes. mRNA knockdown was measured by quantitative RT-PCR in cell-based assays, revealing that over 60% of siRNA sequences designed by DSIR silenced their target genes by at least 70%. Silencing efficacy was sustained even when low siRNA concentrations were used. This systematic analysis revealed in particular that, for a subset of genes, the efficiency of siRNA constructs significantly increases when the sequence is located closer to the 5′-end of the target gene coding sequence, suggesting the distance to the 5′-end as a new feature for siRNA potency prediction. A new version of DSIR incorporating these new findings, as well as the list of validated siRNA against the tested cancer genes, has been made available on the web (http://biodev.extra.cea.fr/DSIR).
Integration of a Dual GPS and ISM Antenna PIFA in a Human Body Patch for Elderly Tracking  [PDF]
B. Hajjine, C. Escriba, P. Acco, G. Soto Romero, E. Campo, D. Filhol, A. Gaudon, L. Bories, J. Y. Fourniols
Open Journal of Antennas and Propagation (OJAPr) , 2016, DOI: 10.4236/ojapr.2016.42004
Abstract: This paper introduces the development of two Printed Inverted F Antennas (PIFA) to be integrated in a patch worn on the back of human body. This study is part of SACHA project (Search And Computerize Human Acts) whose main aim is to design a tracking device for monitoring the elderly suffering from Alzheimer disease. The first antenna frequency is 868 MHz and will be used to communicate with a specific SIGFOX communication technology. A second frequency (1575.42 MHz) is used for GPS geolocation. The proposed development is a part of research in Human Health Monitoring field, based on the monitoring of the behavior, the location and the position of the patient, and could deeply help the medical team or family to instantly respond through a warning generation.

Abstract: Highly luminescent isolated polydiacetylene (PDA) chains in a new diacetylene crystal are studied. The diacetylene crystal structure and theoretical calculations suggest that the chains are not planar and more strongly twisted than any known PDA. Yet the chains behave as quasi perfect quantum wires, showing that this behaviour is generic among PDA, provided crystal order is high enough. The exciton energy, E0, is higher than in any other well ordered PDA providing a relationship between E0 and twist angle. On the other hand the exciton binding energy and Bohr radius are significantly affected as demonstrated in electroabsorption experiments (and developed in a companion paper).
Does Child Maltreatment Mediate Family Environment and Psychological Well-Being?  [PDF]
Michael Galea
Psychology (PSYCH) , 2010, DOI: 10.4236/psych.2010.12019
Abstract: This study tried to establish if childhood maltreatment mediates the established relationship between family environ-ment and psychological well-being, in a sample of Maltese university students (N = 312). However, our analysis sug-gested partial mediation only. Moreover, results indicated that abusive families are less loving, socially integrated, organized, and more conflicted. Family environment contributed positively, albeit limited, to cognitive well-being after controlling for child abuse history. In particular, cohesion, do add unique variance to subjective well-being, after controlling for child abuse. This study replicates classic research on the important role that family environment plays in children’s holistic development.
Blended Change Management: Concept and Empirical Investigation of Blending Patterns  [PDF]
Michael REISS
iBusiness (IB) , 2009, DOI: 10.4236/ib.2009.12008
Abstract: In coping with the challenges of revolutionary or evolutionary change processes, change managers do not rely on single tools but on toolboxes containing several domains of tools. The impact of toolboxes on change performance depends both on the complementary inter-domain mix and the intra-domain blending of tools. The patterns of blending are investigated both conceptually and empirically with respect to scope, diversity and coupling of tools. Survey results indicate that blending practices are predominantly determined by rational tool evaluation and by task context.
Single Wire Electrical System  [PDF]
Michael Bank
Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.411092
Abstract: The purpose of this article is to remind of the past and present problems of creating single wire electrical systems. This article presents a new one wire electrical transmission system named B-Line which uses one line only and does not use ground as a second line. The proposed method is to work on all frequencies and on all communication systems including DC systems. It also proposes to work on the concept of the single-pole signal source and single-pole signal load. It illustrates the possibility of cutting the cost of electrical lines and several other advantages in the fields of high frequency communication lines and antennas.

Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.59117

Through the process of trial and error, four unitless equations made up of nine constants have been found with exact answers. The related constants are the Speed of Light [1], the Planck constant [2], Wien’s displacement constant [3], Avogadro’s number [4], the universal Gravity constant [5], the Ampere constant [6], the Faraday constant [7], the Gas constant [8] and Apery’s constant [9].

The Counterfeit Electronics Problem  [PDF]
Michael Pecht
Open Journal of Social Sciences (JSS) , 2013, DOI: 10.4236/jss.2013.17003

Counterfeit electronics have been reported in a wide range of products, including computers, telecommunications equipment, automobiles, avionics and military systems. Counterfeit electronic products include everything from very inexpensive capacitors and resistors to costly microprocessors to servers. This paper describes the counterfeit electronic products problem, and discusses the implication of counterfeit electronics on the electronic supply chain. We then present counterfeit detection and prevention techniques for electronics.
