| In this paper, a modiied form of the ARQ selective repeat protocol with timer control is studied. Transmissions on both the forward and the reverse channels are assumed to experience Markovian errors and therefore the feedback is unreliable. Feedback error recovery is made possible through the use of time diversity. Using results from renewal theory, exact results for the throughput of the pr...

prosite database contains a set of entries corresponding to protein families, which are used to identify the family of a protein from its sequence. although patterns and profiles are developed to be very selective, each may have false positive or negative hits. considering false positives as items that reduce the selectiveness of a pattern, then, the more selective pattern we have, a more accur...

The use of nanopillar array electrodes (NAEs) for biosensor applications was explored using a combined experimental and simulation approach to characterize the role of reaction kinetics and mass transport in glucose detection with NAEs. Thin gold electrodes with arrays of vertically standing gold nanopillars were fabricated and their amperometric current responses were measured under bare and f...

objective(s) rapid tests for detection of streptococcus agalactiae or group b streptococci (gbs) at the onset of labor are needed to permit early intrapartum antibiotic prophylaxis. this study aimed to evaluate the pcr assays targeting the 16s ribosomal rna gene (16s rdna) for detection of the gbs in comparison with a specific culture method. materials and methods two swabs were used to obtain ...

According to modular models of cortical organization, many areas of the extrastriate cortex are dedicated to object categories. These models often assume an early processing stage for the detection of category membership. Can functional imaging isolate areas responsible for detection of members of a category, such as faces or letters? We consider whether responses in three different areas (two ...
