Intracellular recording techniques were used to examine the electrical properties and behavioral function of a novel type of retraction phase interneuron, the N2 ventral (N2v) cells in the feeding network of the snail Lymnaea. The N2vs were compared with the previously identified N2 cells that now are renamed the N2 dorsal (N2d) cells. The N2vs are a bilaterally symmetrical pair of electrotonic...

An overview of numerically reliable algorithms for model reduction is presented. The covered topics are the reduction of stable and unstable linear systems as well as the computational aspects of frequency weighted model reduction. The presentation of available software tools focuses on a recently developed Fortran library RASP-MODRED implementing a new generation of numerically reliable algori...

BACKGROUND Atrial tachyarrhythmias (AT) frequently complicate the perioperative period. Alcohol intoxication is a recognized causative factor for dysrrhythmias. We studied the effects of propofol and thiopental on atrial electrophysiology and vulnerability to AT in a closed-chest porcine model in which AT are facilitated by ethanol. METHODS Thirty-eight pigs were randomly assigned to thiopent...

The CLaC Lab’s system for the PASCAL RTE challenge explores the potential of simple general heuristics and a knowledge-poor approach for recognising paraphrases, using NP coreference, NP chunking, and two parsers (RASP and Link) to produce Predicate Argument Structures (PAS) for each of the pair components. WordNet lexical chains and a few specialised heuristics are used to establish semantic s...

research aims to find a priori paths that are shortest to ensure a specified probability of on-time arrival. The authors (28) have shown that the RASP belongs to a class of multiple-criteria shortest path problems that rely on a dominance relationship to obtain Paretooptimal solutions (7, 16, 29); that is, no further travel time improvements associated with any on-time arrival probability can b...

Mining large graphs has now become an important aspect of many applications. Recent interest in low cost graph traversal on single machines has lead to the construction of systems that use solid state drives (SSDs) to store the graph. An SSD can be accessed with far lower latency than magnetic media, while remaining cheaper than main memory. Unfortunately SSDs are slower than main memory and al...

The official WHO/IUIS database (www.allergen.org) currently lists 77 mould allergens from a variety of protein families. To date, only eight recombinant single allergens from three mould species are available for molecular allergy diagnosis of mould sensitization. These include rAlt a 1, the major allergen in Alternaria alternata-sensitized individuals, and enolase rAlt a 6 with it potential cr...

The main goal of the present work is to decrease the computational burden for optimum design of steel frames with frequency constraints using a new type of neural networks called Wavelet Neural Network. It is contested to train a suitable neural network for frequency approximation work as the analysis program. The combination of wavelet theory and Neural Networks (NN) has lead to the developmen...

Implant positioning is one of the critical factors influencing postoperative outcomes in total hip arthroplasty (THA). Several studies have reported that the postoperative antetorsion (AT) measurement for the femoral stem inserted without navigation showed wide variability. The current authors developed a simple instrument, the Gravity-guide (G-guide), for intraoperative assessment of stem AT a...
