The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed t...

Given a stream with frequencies fd, for d ∈ [n], we characterize the space necessary for approximating the frequency negative moments Fp = ∑ |fd|, where p < 0 and the sum is taken over all items d ∈ [n] with nonzero frequency, in terms of n, , andm = ∑ |fd|. To accomplish this, we actually prove a much more general result. Given any nonnegative and nonincreasing function g, we characterize the ...

The distribution of 6/ 3 integrin in adhesion complexes at the basal membrane in human normal and cancer prostate glands was analyzed in 135 biopsies from 61 patients. The levels of the polarized 6/ 3 integrin expression at the basal membrane of prostate tumor glands were determined by quantitative immunohistochemistry. The 6/ 3 integrin expression was compared with Gleason sum score, pathologi...

BACKGROUND Patients often report neurocognitive difficulties after neuroborreliosis (NB). The frequency and extent of cognitive problems in European patients have been studied incompletely. METHODS Sixty patients received a neurological and neuropsychological work-up 6 months or longer after treatment for proven NB. Quality of life, psychiatric symptom load, and brain atrophy were measured. A...

Problem statement: The faults in digital circuit can be classified broadly as single stuck-atfaults, multiple stuck-ay-faults, stuck-open faults, stuck-on faults, path delay faults, transient faults. Extensive research had been carried out in the field of testing of digital circuits to limit the number of input vectors. The cardinality of the test vectors proposed by many authors was quite high...

background: in the case of sensitive questions such as number of alcoholics known, majority of respondents might give an answer of zero. poisson regression model (p) is the standard tool to analyze count data. however, p provides poor fit in the case of zero inflated counts, when over-dispersion exists. therefore, the questions to be addressed are to compare performance of alternative count reg...
