Axion couplings in grand unified theories

Abstract We show that Dining Bench the couplings of axions to gauge bosons are highly restricted in Grand Unified Theories where the standard model is embedded in a simple 4D gauge group.The topological nature of these couplings allows them to be matched from the UV to the IR, and the ratio of the anomaly with photons and gluons for any axion is fi

Rates of dinosaur body mass evolution indicate 170 million years of sustained ecological innovation on the avian stem lineage.

Large-scale adaptive radiations might explain the runaway success of a minority of extant vertebrate clades.This hypothesis predicts, among other things, rapid rates of morphological evolution during the early history of major groups, as lineages invade disparate ecological niches.However, few studies of adaptive radiation have included deep time d

Study of irritant effect of permethrin impregnated nets on pyrethroid resistant and susceptible genotypes of the mosquito anopheles stephensi

pyrethroid-impregnated bednets have been shown to be one of the most promising tools that have emerged in recent years to control malaria.mosquito may be physically irritated by pyrethroid reducing the time searching for blood meals,or driving them away.permethrin impregnated nets also may deter a proportion of mosquitoes from entering houses.irrit

ARS2 Plays Diverse Roles in DNA Damage Response, Fungal Development, and Pathogenesis in the Plant Pathogenic Fungus Fusarium graminearum

Arsenite-resistance protein 2 (Ars2) is an important nuclear protein involved in various RNA metabolisms in animals and plants, but no Ars2 ortholog has been studied in filamentous fungi.Although it is an essential gene in most model eukaryotes, FgARS2 null mutants Dining Bench were viable in the plant pathogenic fungus Fusarium graminearum.The del
