Phase Transitions and Symmetry Breaking in Genetic Algorithms with Crossover
, 2006 In this paper, we consider the role of the crossover operator in genetic algorithms. Specifically, we study optimisation problems that exhibit many local optima and consider how crossover affects the rate at which the population breaks the symmetry of ...

Nonparametric Approaches to the Analysis of Crossover Studies
Statistical Science, 2004 We illustrate nonparametric, and particularly rank-based analyses of crossover studies, designs in which each subject receives more than one treatment over time. Principles involved in using the Wilcoxon rank sum test in the simple two-period, two-treatment crossover are described through theory and example.

A Crossover Comparative Study with Two Bulk Laxatives [PDF]
Journal of International Medical Research, 1983 Twenty elderly in-patients suffering from severe constipation were treated once daily for 2 weeks with each of two bulk laxatives. The preparations were allocated randomly as the first and second preparation. Agiolax, the new preparation, contained 15 mg senna glucosides, the old preparation, Lunelax comp., contained 25 mg senna glucoside A + B per ...

Respiratory Research, 2021 Background Positive associations between ambient PM2.5 and cardiorespiratory disease have been well demonstrated during the past decade. However, few studies have examined the adverse effects of PM2.5 based on an entire population of a megalopolis.

Sound velocity and multibranch bogoliubov spectrum of an elongated fermi superfluid in the BEC-BCS crossover [PDF]
, 2005 We study properties of excited states of an elongated Fermi superfluid along the Bose-Einstein-condensate-BCS crossover including the unitarity limit. Analytic expressions for the sound velocity in an inhomogeneous as well as homogeneous Fermi superfluid

Advanced Functional Materials, EarlyView.This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.
