The relative linear order of most genes on bacterial chromosomes is not conserved over evolutionary timescales.One explanation is that selection is weak, allowing recombination to randomize pusher gene order by genetic drift.However, most chromosomal rearrangements are deleterious to fitness.In contrast, we propose the hypothesis that rearrangement
ObjectivesWith the increased use of computed tomography (CT) in clinics, dose reduction is the most important feature people seek when considering new CT techniques or applications.We developed an intensity-weighted region-of-interest (IWROI) Bubblers imaging method in an exact half-fan geometry to reduce the imaging radiation dose to patients in c
Evolutionary benefits of task fidelity and improving information acquisition via multiple transfers of materials between individuals in a task partitioned system have been shown before, but in this paper we provide a mechanistic explanation of these phenomena.Using a simple mathematical model describing the individual interactions of the wasps, we
"nObjective: abortion either medical or KNIT BOTMSWEATS criminal has distinctive physical, social, and psychological side effects.Detecting types and frequent psychological side effects of abortion among post abortion care seeking women in Tehran was the main objective of the present study."n Method: 278 women of reproductive age (15-49) inter
Illumination is a crucial factor in hyperspectral imaging systems.In this respect, this work is focused on analyzing the influence of the light power source in acquiring hyperspectral images.To this end, a custom regulated power supply was designed and developed.This power supply was then integrated into a hyperspectral acquisition system, and seve
