Controlling segregation is both a practical and a theoretical challenge. Using a novel drum design comprising concave and convex geometry, we explore, through the application of both discrete particle simulations and positron emission particle tracking, a means by which radial size segregation may be used to drive axial segregation, resulting in an order of magnitude increase in the rate of sep...

In the experiments reported here, we attempted to find out more about how the auditory system is able to separate two simultaneous harmonic sounds. Previous research (Halikia & Bregman, 1984a, 1984b; Scheffers, 1983a) had indicated that a difference in fundamental frequency (F0) between two simultaneous vowel sounds improves their separate identification. In the present experiments, we looked a...

Segregation discovery consists of finding contexts of segregation of social groups distributed across units or communities. The SCube system implements an approach for segregation discovery on top of frequent itemset mining, by offering to the analyst a multi-dimensional (segregation) data cube for exploratory data analysis. The demonstration first guides the audience through the social science...

Grain boundary and surface segregation of Bi in Cu were investigated under identical conditions. Cu bicrystals containing deliberately made internal cavities at the interfaces were doped with Bi, annealed at different temperatures, and broken in an Auger microprobe. The segregation level at the free surfaces was found to be higher than that at grain boundaries. Grain-boundary and surface segreg...

We propose a set of basic properties that any reasonable segregation index should have. We then fully characterize the class of segregation indices that satisfy these basic properties. We show that every such index has a particular simple form. Finally, we show that with one rarely used exception, each index defined in the literature violates one or more of our basic properties. Journal of Econ...

It is shown how linear genetic algebras, ordinarily applied in situations with discrete time, will also simplify certain systems of differential equations in time continuous models. These models describe the variation of genotype frequencies in infinite populations in different mating systems. The cases considered include matings between individuals randomly drawn from the population at each mo...

Urban segregation represents a significant barrier to achieving social inclusion in cities. To mitigate this problem, it is necessary to implement policies founded upon a better understanding of segregation dynamics. This paper proposes MASUS, a multi-agent simulator for urban segregation, which provides a virtual laboratory for exploring the impacts of different contextual mechanisms on the em...

This article examines the influence of resource dependence and institutional processes on post-Civil Rights Act changes in private sector workplace segregation. We use data collected by the U.S. Equal Employment Opportunity Commission from 1966 through 2000 to examine organizations embedded within their firm, industry, local labor market and federal regulatory environments. Sex segregation decl...

The successful inheritance of genetic information across generations is a complex process requiring replication of the genome and its faithful segregation into two daughter cells. At each replication cycle there is a risk that new DNA strands incorporate genetic changes caused by miscopying of parental information. By contrast the parental strands retain the original information. This raises th...

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 stream s...
