results the predominant genotype among bahraini patients was type 1 (36.71%), followed by genotypes 3 and 4 (15.6% each) and the lowest frequency was found for genotype 2 (3.9%). among genotype 1, subtype 1b had the highest frequency (21.09%), followed by subtype 1a (14.06%). among genotype 3, subtype 3a had the highest frequency (11.72%), while among genotype 4, most of subtypes were undetermi...

BACKGROUND/AIMS Data on normal stool form and frequency, which are important for defining constipation, are scanty; hence, we studied these in an eastern Indian population. METHODS One thousand and two hundred apparently healthy asymptomatic subjects were evaluated for predominant stool form (Bristol chart with descriptor) and frequency. Data on demographic and life-style (diet and physical a...

Domestic fleas were collected in 12 villages in the western Usambara Mountains in Tanzania. Of these, 7 are considered villages with high plague frequency, where human plague was recorded during at least 6 of the 17 plague seasons between 1986 and 2004. In the remaining 5 villages with low plague frequency, plague was either rare or unrecorded. Pulex irritans, known as the human flea, was the p...

As the interconnect technology is shrinking into nanometres regime the bandwidth of long interconnects reduces. Hence an accurate modelling of bandwidth is essential for the estimation of performance of VLSI interconnects. With the increase in frequency towards the giga hertz range, the analysis of high frequency effects like skin effect etc. are becoming extensively predominant and important f...

it is well known that ground-shaking site effect caused by an earthquake can vary significantly within a small distance. this is because at sites having soft soil and/or topographic and basement undulations, seismic energy gets trapped, leading to amplification of vibration that may cause considerable damage to man-made structures. theoretical analysis and observational data have shown that eac...

Discrete time-varying autoregressive moving average (ARMA) models are used to describe realistic earthquake ground motion time histories. Both amplitude and frequency nonstationarities are incorporated in the model. An iterative Kalman filtering scheme is introduced to identify the time-varying parameters of an ARMA model from an actual earthquake record. Several model verification tests are pe...

Visual tracking tests have been used to obtain a quantified statistical description of the involuntary movements of the arm about the elbow joint in a group of patients suffering from athetoid cerebral palsy. Three separate components of involuntary activity can be recognized and it is possible that each may be a different physiological mechanism. First there are irregular movements which are r...
