regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
A hypothesis is presented that electronic and vibrational resonant energy states are important in biochemical reactions due to their coupling to hydrogen transfer reactions. The hypothesis is based upon (1) the involvement of hydrogen in most biochemical reactions, (2) the unique abiity of hydrogen to act as an energy trap for resonant energy and (3) demonstrations of the coupling of resonant e...
abstract This paper presents a taxonomy of methods for detecting race conditions in parallel programs, shows how recent results t into the taxonomy, and presents some new results for previously unexamined points in the taxonomy. It also presents a taxonomy of \races" and suggested terminology.
Motivation: Enzyme function prediction is an important problem in post-genomic bioinformatics. There are two general methods for solving the problem: annotation transfer from a similar annotated protein, and machine learning approaches that treat the problem as classification against a fixed taxonomy, such as Gene Ontology or the EC hierarchy. These methods are suitable in cases where the funct...
The ability to automatically extract information from the footnotes of financial statements simplifies access to critical information concerning public companies. However, extraction can be particularly challenging due to great variations in the filing structure and terminologies used. Hierarchical formalization of text becomes a necessity in such circumstances. This is facilitated by the creat...
Taxonomy is the discipline in biology aimed at characterizing and naming taxa and taxonomy plays a major role in conserving biodiversity. The central unit of taxonomy is species and generating biological information requires naming of species. Thousands of species are being named every year since the advent of Linnaean nomenclature in 1758. Alpha taxonomy relates to species level characterizati...
There is little agreement in the scientific literature about what the terms "driver distraction" and "driver inattention" mean, and what the relationship is between them. In 2011, Regan, Hallett and Gordon proposed a taxonomy of driver inattention in which driver distraction is conceptualized as just one of several processes that give rise to driver inattention. Since publication of that paper,...
در این پژوهش، جنس .vicia l در ایران مورد بازنگری تاکسونومیکی قرار گرفت. مطالعه 500 نمونه جمع آوری شده و نمونه های هرباریومی دیگر منجر به شناسایی یک زیر گونه جدید برای فلور ایران، .v. villosa roth. subsp. dasycarpa (ten.) cav، جمع آوری و شناسایی دو گونه v. lathyroides و v. mollis که تا کنون در هرباریوم های کشور موجود نبود، احیای بخش های crocea & lenticula ، انتقال گونه های بخش cassubica...
دانه گرده 8 گونه بومی ایران از جنس nepeta l.، بخش sect. psilonepeta بوسیله میکروسکوپ الکترونی (sem) مورد بررسی قرار گرفت. تفاوت های مشخصی از نظر انـــدازه و تزئینات سطح دانه گرده بین گونه ها بخصوص با گونه n. denudata مشاهده شد. نتایج بدست آمده همراه با تفاوت های مورفولوژیکی و آناتومیکی این گونه نشان داد که گونه n. denudata از گونه های دیگر این بخش متمایز بوده و پیشنهاد می شود که گونه n. denudat...
قبیله های arundineae وdanthonieae جهت نگارش فلور ایران مورد مطالعه و بررسی قرار گرفت. در بررسی جنس phragmites مشخص شد که این جنس درایران دو گونه دارد. محدوده انتشار phragmites karka علاوه بر منطقه ای محدود از جنوب شرق ( دشت لوت- بلوچستان ) که اولین بار توسط لئونارد گزارش شده است، مناطقی از جنوب استان کرمان ( بم ) و شمال شرق ایران ( خراسان )را نیز شامل می شود. با توجه به محدود بودن دامنه انتشار ...
