Objectives: This study investigated the efficacy of working memory training for improving working memory capacity and related auditory stream segregation in auditory processing disorders children. Methods: Fifteen subjects (9-11 years), clinically diagnosed with auditory processing disorder participated in this non-randomized case-controlled trial. Working memory abilities and auditory strea...

Segregation of granular materials composed of different-sized particles has important repercussions in various industrial processes and natural phenomena, but predicting size segregation remains a challenging problem. To address this problem, we have developed a theoretical model that captures the interplay between advection, segregation, and diffusion in size bidisperse granular materials. The...

A study of occupational race and sex segregation was performed on time series, census data from 1940 to 2000. Modernization / neoclassic economic theories and institutional / queuing theories were tested in the analyses. Modernization theory suggests that over time, occupational segregation will decrease, while institutional/queue theory suggests segregation will not decline due to rigidities a...

through an application of genetic engineering, genes from a soil bacterium bacillus thuringiensis (bt) which confer resistance to pests were transferred into rice. successful employment of genetic engineering in traditional breeding programs is dependent upon stable transmission of transgene in transgenic varieties. three different segregating f2 populations were developed from a cross between ...

Meiotic crossovers (COs) are crucial for ensuring accurate homologous chromosome segregation during meiosis I. Because the double-strand breaks (DSBs) that initiate meiotic recombination greatly outnumber eventual COs, this process requires exquisite regulation to narrow down the pool of DSB intermediates that may form COs. In this paper, we identify a cyclin-related protein, CNTD1, as a critic...

extended abstract 1. introduction spatial segregation in tabriz metropolitan physically indicates some poor infrastructure indexes such as lack of arterial transportation networks, lack of water supply and sewage networks, inadequate housing, increasing and inhumane density, lack of service per capita, but from a social and cultural perspective, it is the vehicle of marginal identity that in in...

Drawing on insights from Shannon’s (1948) seminal paper on Information Theory, we propose that all measures of segregation and inequality are united within a single conceptual framework. We argue that segregation is fundamentally analogous to the loss of information from an aggregation process. Integration is information loss and segregation is information retention. Specifying the exact theore...

Kinetochore components have catalytic as well as structural activities. New evidence illustrates how these proteins integrate spindle morphogenesis with regulation of the timing and accuracy of chromosome segregation.

BACKGROUND Neighbourhood segregation has been described as a fundamental determinant of physical health, but literature on its effect on mental health is less clear. While most previous research has relied on conceptualised measures of segregation, Northern Ireland is unique as it contains physical manifestations of segregation in the form of segregation barriers (or 'peacelines') which can be ...
