Evolutionary psychology has revolutionized research on human mate choice and sexual attraction in recent years, combining a rigorous Darwinian framework based on sexual selection theory with a loosely cognitivist orientation to task analysis and mechanism modelling. This hard Darwinian, soft computational approach has been most successful at revealing the adaptive logic behind physical beauty, ...

rumbs (Crb) helps flies distinguish apical from basal in their epithelia. Now two new studies show that it is required for cell expansion independently of its specification of apical polarity. During cell expansion, the apical domain of photoreceptors elongates perpendicular to the apical–basal axis so that the domain can extend from the top to the bottom of the fly eye. The process may be cons...

RNA splicing, the process that removes introns from pre-mRNA and links exons together to generate the fully mature messenger RNA (mRNA), is a complicated and highly regulated process. Splicing is catalyzed by the spliceosome, a large RNA-protein complex composed of several small nuclear ribonucleoprotein complexes (snRNPs) that each have a specific task during splicing. Correct splicing is impo...

Turn to turn fault is one of the major internal failures in the power transformers that if it is not quickly detected, can be extended and led to a complete transformer breakdown. So, the diagnosis and location of the turn to turn fault of the power transformer, as one of the most important equipment in the power system, is the main objective of this paper. For this purpose, a detailed model of...

SEE PAGE 804 O ne of the most challenging aspects of obesity is its link to “metabolic syndrome,” when abdominal obesity is accompanied by high fasting blood glucose, low levels of high-density lipoprotein cholesterol, high levels of triglycerides, and elevated blood pressure. With rising obesity rates, metabolic syndrome is likely to become more common in the years ahead (1). Although progress...

It has now been 3 years since the von Willebrand factor (VWF)-cleaving protease implicated in thrombocytopenic purpura (TTP) pathogenesis was identified as ADAMTS13 (a disintegrin-like and metalloprotease with thrombospondin type 1 motif 13). More than 50 ADAMTS13 mutations resulting in familial TTP have been reported. Considerable progress has also been realized toward understanding the role o...

n the recent years, the knowledge of stylistics has experienced some new branches. thanks to the recent efforts of a group of linguists, traditional stylistics has changed its branches in favour of genres, rather than the types of prose and verse. up until two decades ago, stylistics mainly focused on the form of the text, and the genres were almost ignored or overlooked. however, in the light ...
