Disturbed Binaries: The Early Phases

Models of the non-thermal emission from early-type binaries

The powerful wind-wind collision in massive star binaries creates a region of high temperature plasma and accelerates particles to relativistic energies. I briefly summarize the hydrodynamics of the wind-wind interaction and the observational evidence, including recent γ-ray detections, of non-thermal emission from such systems. I then discuss existing models of the non-thermal emission and the...

Dark and disturbed: a new image of early angiosperm ecology

—Better understanding of the functional biology of early angiosperms may clarify ecological factors surrounding their origin and early radiation. Phylogenetic studies identify Amborella, Nymphaeales (water lilies), Austrobaileyales, and Chloranthaceae as extant lineages that branched before the radiation of core angiosperms. Among living plants, these lineages may represent the best models for ...

Effect of oral genistein administration in early and late phases of allergic encephalomyelitis

Objective(s):Experimental allergic encephalomyelitis (EAE) is an autoimmune disease validated as animal model of multiple sclerosis (MS). Administration of genistein, a phytoestrogenic component of soy, to mice at the onset of EAE is known to attenuate the clinical signs of the disease. The potential effects of genistein on established EAE is less studied. In the current study, we aimed to comp...

Safety activities during early software project phases

This paper describes how methods taken from safety-critical practises can be used in development of business-critical software. The emphasis is on the early phases of product development, and on use together with the Rational Unified Process. One important part of the early project phases is to define safety requirements for the system. This means that in addition to satisfying the need for fun...
