We present a new approach to path planning, called the \Ariadne's clew algorithm". It is designed to nd paths in high-dimensional continuous spaces and applies to robots with many degrees of freedom in static, as well as dynamic environments | ones where obstacles may move. The Ariadne's clew algorithm comprises two sub-algorithms, called search and explore, applied in an interleaved manner. ex...

This paper describes a system for interannotator agreement analysis of ERE annotation, focusing on entity mentions and how the higher-order annotations such as EVENTS are dependent on those entity mentions. The goal of this approach is to provide both (1) quantitative scores for the various levels of annotation, and (2) information about the types of annotation inconsistencies that might exist....

This paper introduces the parallel Chinese-English Entities, Relations and Events (ERE) corpora developed by Linguistic Data Consortium under the DARPA Deep Exploration and Filtering of Text (DEFT) Program. Original Chinese newswire and discussion forum documents are annotated for two versions of the ERE task. The texts are manually translated into English and then annotated for the same ERE ta...

The species responsible for the broad extended red emission (ERE), discovered in 1975 and now known to be widespread throughout the Galaxy, still is unidentified. Spanning the range from approximately 540 to 900 nm, the ERE is a photoluminescent process associated with a wide variety of different interstellar environments. Over the years, a number of plausible candidates have been suggested, bu...

The estrogen pathway plays an important role in the etiology of human endometrial carcinoma (EC). We examined whether estrogen biosynthesis in the tumor microenvironment promotes endometrial cancer. To examine the contribution of stromal cells to estrogen signaling in EC, we used reporter cells stably transfected with the estrogen response element (ERE) fused to the destabilized green fluoresce...

The importance of computational methods for the simulation and analysis of biological systems has increased during the last years. In particular, methods to predict binding energies are developing not only with the aim of ranking the affinities between two or more complexes, but also to quantify the contribution of different types of interaction. In this work, we present the application of HINT...

Les moyens d’action souvent privilégiés pour la sauvegarde de planète comme sanctuarisation zones protégées et gestion production/consommation paraissent aujourd’hui insuffisants endiguer dégradation notre environnement. Nous proposons dans cette contribution une double réflexion qui vise (1) à alimenter le débat sur rapport l’Homme Nature (2) montrer comment l’art contemporain peut contribuer ...

Upon binding to estrogens, the ERα nuclear receptor acts as a transcription factor and mediates a multitude of cellular functions central to health and disease. Herein, using isothermal titration calorimetry (ITC) and circular dichroism (CD) in conjunction with molecular modeling (MM), we analyze the effect of symmetric introduction of single nucleotide variations within each half-site of the e...

Eutypine (4-hydroxy-3-[3-methyl-3-butene-1-ynyl] benzaldehyde) is a toxin produced by Eutypa lata , the causal agent of eutypa dieback of grapevines. Recently, a eutypine detoxifying gene (Vr-ERE ) encoding an NADPH-dependent aldehyde reductase which converts eutypine into the corresponding alcohol, eutypinol, a non-toxic form of the toxin, has been cloned. We report here the obtention of trans...
