A spring-loaded mechanism can explain the activation process for a protein that has a crucial role in maintaining the genomic integrity of immature eggs cells.

evidence provided from studies in iran points to a possible bias in application of the standard epi cluster sampling procedure, when carried out in populations with highly variant birth rates, tends to over-represent the low birth rate, i.e. higher socio-economic, strata, and if the entity under study shows significant socio-economic gradient, then the estimates arrived at by this method might ...

proteomics refers to the analysis of expression, localization, functions, posttranslational modifications, and interactions of proteins expressed by a genome at a specific condition and at a specific time. current proteomic tools allow large-scale, high-throughput analyses for the detection, identification, and functional investigation of proteome. in this review, we have focused on the proteom...

BACKGROUND AND OBJECTIVE hearing impairment is common in older adults and has been implicated in the risk of disability and mortality. We examined the association between hearing impairment and risk of incident disability and all-cause mortality. DESIGN AND SETTING prospective cohort of community-dwelling older men aged 63-85 followed up for disability over 2 years and for all-cause mortality...

PURPOSE We compared the prevalence of disability among older American Indians and Alaska Natives (AI/ANs) with that among their African American and White peers, then examined sociodemographic characteristics associated with disability among AI/ANs. DESIGN AND METHODS We analyzed the 5% 2000 Census Public Use Microdata Sample. We assessed disability by functional limitation, mobility disabili...

OBJECTIVE To assess the construct and convergent validity of the 16 items of the Late-Life Disability Instrument (LLDI) in Latin American seniors. METHOD Exploratory and confirmatory factor analyses were performed to assess the factor structure of frequency and limitation sub-scales of the LLDI. ANOVA and t test were used to determine the convergent and construct validity of the LLDI by explo...

A recently proposed method in deep learning groups multiple neurons to capsules such that each capsule represents an object or part of object. Routing algorithms route the output from lower-level layers upper-level layers. In this paper, we prove state-of-the-art routing procedures decrease expressivity networks. More precisely, it is shown EM-routing and routing-by-agreement prevent networks d...

In modern railway electric infrastructure design there are two major concerns that should be considered as touch voltage and stray current. The first problem is step which endangers human safety even to deathly situations. Second current leads corrosion of metallic infrastructure. Since has higher priority early on systems grounded the rail earth but this caused problem. Thus these problems han...
