persian natural language processing (nlp) researchers have many limitations to access linguistic tools which are suitable for text processing. therefore, researchin persian text processing is very limited. since dataset is an important requirement for experiments and their evaluation, we aimed to create appropriate corpora for information retrieval and natural language processing in persian. th...

Tags are markers placed on or in animals to identify an individual. Animals are tagged to estimate their abundance as well as rates of growth, fishing mortality, natural mortality, and movement. In many studies, a tagged animal is assumed to retain its tag permanently. This assumption, however, is not valid for certain types of tags. Consequently, many attempts have been made to estimate tag sh...

In response to increases in cohabitation in the United States, researchers have recently focused on differences between cohabiting and marital unions. One of the more consistent findings in this emerging literature has been a higher rate of domestic violence among cohabiting couples. A prominent explanation for this finding is that cohabitors are not subject to the institutionalized social cont...

We characterize those formulas of MSO monadic second order logic that are safe for bisim ulation formulas de ning binary relations such that any bisimulation is also a bisimulation with respect to these de ned relations Every such formula is equivalent to one constructed from calculus tests atomic actions and the regular operations The proof uses a characterization of completely additive calcul...

Protein function may be modulated by an event occurring far away from the functional site, a phenomenon termed allostery. While classically allostery involves conformational changes, we recently observed that charge redistribution within antibody can also lead to allosteric effect, modulating kinetics of binding target antigen. In present work, study association polyhistidine tagged enzyme (pho...

This paper reports a versatile egfp-tagged pFL61based expression vector system which allows the production on yeast of homoand heterologous proteins fused with the Enhanced Green Fluorescent Protein (EGFP) at the C-terminus. This expression system, which involves a fluorescent protein, readily allows both to verify the expression and to localize the protein in the yeast cell. The vector carries...

Vulnerability of biomolecules to ultraviolet radiation is intimately linked to deexcitation pathways: photostability requires fast internal conversion to the electronic ground state, but also intramolecular vibrational redistribution and cooling on a time scale faster than dissociation. Here we present a protocol to disentangle slow and non-hazardous statistical dissociation from prompt cleavag...

The DNA photocleavage reaction of mismatch-selective Rh complexes has been analyzed by MALDI-TOF mass spectrometry as well as gel electrophoresis analysis of radioactively tagged oligonucleotides. Analogous results are obtained with these two techniques showing site-specific cleavage neighboring the mismatch to yield primarily 5'- and 3'-phosphate termini. Additional intermediates and products ...
