Expressed sequence tags, abbreviated ESTs, are DNA fragments experimentally derived from expressed portions of genes. Clustering of ESTs is essential for gene recognition and understanding important genetic variations such as those resulting in diseases. In this paper, we present the design and development of a parallel software system for EST clustering. The novel features of our approach incl...

ltimamente se han acercado a mí distinguidos miembros de la Sociedad Mexicana de Cardiología para preguntarme sobre el origen y el significado del lema de la Sociedad: “Plus est en toi ”. Hace más de 20 años que el lema fue adoptado por voto unánime de los Socios. Con el objeto de dar respuesta a la inquietud de los miembros jóvenes y actualizar la importancia que para la Sociedad tiene su lema...

In epistemic logic, Kripke structures are used to model the distribution of information in a multi-agent system. In this paper, we present an approach to quantifying how much information each particular agent in a system has, or how important the agent is, with respect to some fact represented as a goal formula. It is typically the case that the goal formula is distributed knowledge in the syst...

Trimming procedures are an important part of the sequence analysis pipeline in an EST Sequencing Project. In general, trimming is done in several phases, each one detecting and removing some kind of undesirable artifact, such as low quality sequence, vectors or adapters sequence, and contamination. However, this strategy often results in a phase being unable to recognize its target because part...

The Diatom EST database provides integrated access to expressed sequence tag (EST) data from two eukaryotic microalgae of the class Bacillariophyceae, Phaeodactylum tricornutum and Thalassiosira pseudonana. The database currently contains sequences of close to 30,000 ESTs organized into PtDB, the P.tricornutum EST database, and TpDB, the T.pseudonana EST database. The EST sequences were cluster...

Within the realm of nano-, bio-, info- and cogno- (or NBIC) technosciences, the 'power to change the world' is often invoked. One could dismiss such formulations as 'purely rhetorical', interpret them as rhetorical and self-fulfilling or view them as an adequate depiction of one of the fundamental characteristics of technoscience. In the latter case, a very specific nexus between science and te...

dans la plupart des cas, la reponse des differents systemes juridiques aux questions juridiques est identique ou rapprochee. ceci se justifie, sans doute, par le fait que la raison humaine ala recherche de solutions pour les problemes juridique arrive aux memes resultants, meme si ceux s'expriment differemment, la derogation au principe pacta sunt servanda sous certaines conditions en est ...
