We examine the environment of star-forming galaxies selected in the 2dFGRS. We find that bright star-forming galaxies display a significant deficit of faint neighbours relative to passive galaxies. If a deficit in fainter companions implies a smaller mass halo, data support a scenario predicting star-formation to be suppressed in all systems more massive than 1013M⊙, rather than in clusters only.

Abstract What is indoctrination? This paper clarifies and defends a structural epistemic account of indoctrination according to which the inculcation closed-minded belief caused by “epistemically insulating content.” content contains proviso that serious critical consideration relevant alternatives one's reprehensible whether morally or epistemically. As such, it does not demand be type unethic...

: optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (pr) crystal are investigated. each crystal can be supported the spatial soliton, and at least one must be photovoltaic. the two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...

REVIEW QUESTION What is the effectiveness of bright light therapy (BLT) on depressive symptoms in older adults with non-seasonal depression? REVIEW OBJECTIVE The review objective is to determine the current evidence related to the effectiveness of BLT on depressive symptoms in older adults with non-seasonal depression.

The Drosophila single-minded and trachealess bHLH-PAS genes control transcription and development of the CNS midline cell lineage and tracheal tubules, respectively. We show that Single-minded and Trachealess activate transcription by forming dimers with the Drosophila Tango protein that is an orthologue of the mammalian Arnt protein. Both cell culture and in vivo studies show that a DNA enhanc...
