This paper proposes a data reduction and hypothesis testing methodology that can be used to perform hypothesis testing with data commonly collected in benchmarking studies. A reduced-form performance vector and a reduced-form set of decision variables are constructed using the multivariate data reduction techniques of principal component analysis and exploratory factor analysis. Reductions in d...

From genetic regulatory networks to nervous systems, the interactions between elements in biological networks often take a sigmoidal or S-shaped form. This paper develops a probabilistic characterization of the parameter space of continuous-time sigmoidal networks (CTSNs), a simple but dynamically-universal model of such interactions. We describe an efficient and accurate method for calculating...

A study was carried out of 1086 men aged 16-65 inclusive who were admitted under nine consultants to eight hospitals in Wessex for elective repair of an inguinal hernia. The mean postoperative stay was 5.7 +/- SD 2.7 days. For different consultants operating at any one hospital the mean postoperative stays were similar, whereas for consultants who operated at more than one hospital they were si...

Several animal viruses inhibit host protein synthesis, but only some members of the picornavirus group are known to do so by cleaving translation initiation factor eIF4G. Here we report that infection of human CD4(+) cells with HIV-1 also leads to proteolysis of eIF4G and profound inhibition of cellular translation. Purified HIV-1 protease directly cleaves eIF4GI at positions 678, 681, and 1086...

The aim of this study was to determine the prevalence of HIV co-infection among TB patients in Dabat district, northwest Ethiopia. Medical records of 1086 pulmonary and extrapulmonary tuberculosis patients registered from 2009 to 2012 at two health centers in the district were reviewed. HIV status was determined on 849 (78.2%) patients. The prevalence of HIV co-infection was 97 (11.4%). The maj...

The purpose of this study is two-fold: (1) to examine students’ perceptions their capabilities in respective programs, and (2) the quality teaching learning environment. A stratified sample college students was chosen consisted 1086 (320 male 29.5%, 766 female 70.5%) from 3rd 4th-year students. T-test results indicated that tend be more self-managed cooperative learners than students, where sco...
