RNA secondary structure prediction is a compute intensive task that lies at the core of several search algorithms in bioinformatics. Fortunately, the RNA folding approaches, such as the Nussinov base pair maximization, involve mathematical operations over affine control loops whose iteration space can be represented by the polyhedral model.

Syntactic theories based on the concept of dependency have a long tradition. Tesni` re (Tesni` re, e e 1959) was the first who systematically described the sentence structure in terms of binary relations between words (dependencies), which form a dependency tree (D-tree for short). D-tree itself does not presume a linear order on words. However, any its surface realization projects some linear order relation (called also precedence). Some properties of surface syntactic structure can be expressed only in terms of both dependency (or its transitive closure called dominance) and precedence.

This paper describes a novel event-matching strategy using features obtained from the transitive closure of dependency relations. The method yields a model capable of matching events with an F-measure of 66.5%. training and test instance in a feature space. Conceptually, our features are of three different varieties. This section describes the first two kinds, which we call “low-level” features, in that they attempt to capture how much of the basic information of an event e is present in a sentence s. 2.1 Lexical features ...

3-Phosphoglycerate kinase (PGK) is a typical two-domain hinge-bending enzyme with a well-structured interdomain region. The mechanism of domain–domain interaction and its regulation by substrate binding is not yet fully understood. Here the existence of strong cooperativity between the two domains was demonstrated by following heat transitions of pig muscle and yeast PGKs using differential scanning microcalorimetry and fluorimetry.

Cyclosporin A induces closure of the mitochondrial permeability transition pore. We aimed to investigate whether this closure results in concomitant increases in mitochondrial membrane potential (DWm) and the produc-tion of reactive oxygen species.

First, you will need to decide if you are going to invest in clear plastic envelopes or use any number of paper envelopes commercially available. If you use paper, we suggest you try and find an envelope with clasp closure system, not an adhesive one. Remember, your entry will be opened and closed many times during its judging. A paper envelope is shown in example B to enter a brochure. Note, the larger label is permanently affixed (we suggest 3M’s Supper 77 spray glue) to the exterior of the envelope and the smaller label to the back of the piece itself. An...

Fostering the development of a ubiquitously networked society, connected over high-capacity networks, is a widely shared goal among both developed and developing countries. High capacity networks are seen as strategic infrastructure, intended to contribute to high and sustainable economic growth and to core aspects of human development. In the pursuit of this goal, various countries have, over the past decade and a half, deployed different strategies, and enjoyed different results.

In utero, the placenta is the main site for gas exchange for the developing foetus and the blood flow to the foetal lung is minimal. Blood from the right ventricle bypasses the lungs and passes directly from the pulmonary artery to the aorta via a foetal vessel called the arterial duct. After birth, a number of changes occur in transition from the foetal to the newborn circulation including expansion of the lungs (which reduces pulmonary vascular resistance) and closure of the arterial duct, so that blood now perfuses the lungs.
