SUMMARY We present a new implementation of the shortest path method (SPM) that calculates accurate traveltimes in arbitrarily large model spaces without requirement computational times and amounts memory, an inherent problem Dijkstra's-like algorithms. The multiple graph realizations is based upon sampling space, using numerous random graphs. performance this compared against conventional way t...

Chemical Named Entity Recognition (NER) is the basic step for consequent information extraction tasks such as named entity resolution, drug-drug interaction discovery, extraction of the names of the molecules and their properties. Improvement in the performance of such systems may affects the quality of the subsequent tasks. Chemical text from which data for named entity recognition is extracte...

We present a simple algorithm for estimating the cardinality of a set I, based on a RandomSample(I) primitive that returns an element of I uniformly at random. Our algorithm with probability (1−perr) returns an estimate of |I| accurate within a factor (1 ± δerr) invoking RandomSample(I) at most O (

When properly applied, stereology is a very robust and efficient method to quantify a variety of parameters from biological material. A common sampling strategy in stereology is systematic random sampling, which involves choosing a random sampling [corrected] start point outside the structure of interest, and sampling relevant objects at [corrected] sites that are placed at pre-determined, equi...
