A discontinuous change in the size of an attractor is the most easily observed type of global bifurcation. More generally, an explosion is a discontinuous change in the set of recurrent points. An explosion often results from heteroclinic and homoclinic tangency bifurcations. We prove that, for one-dimensional maps, explosions are generically the result of either tangency or saddle-node bifurca...

Durch das ATEX-konforme Anlagenkonzept Condux Compact wird die Installation einer leistungsfähigen Mahlanlage für zahlreiche Produkte nun deutlich einfacher, denn Explosionsschutzventile oder Explosions-Unterdrückungseinrichtungen, Explosions-Entkoppelung

The expense, danger, planning and precision required to create explosions suggests that the computational visual modelling of explosions is worthwhile. However, the short time scale at which explosions occur, and their sheer complexity, poses a difficult modelling challenge. After describing the basic phenomenology of explosion events, we present an efficient computational model of isotropic bl...

Supernova (SN) explosions are one of the most energetic---and potentially lethal---phenomena in the Universe. We show that the Scorpius-Centaurus OB association, a group of young stars currently located at approximately 130 pc from the Sun, has generated 20 SN explosions during the last 11 Myr, some of them probably as close as 40 pc to our planet. The deposition on Earth of (60)Fe atoms produc...

Observations of type Ia supernovæ at high redshifts have become an important tool for studying the geometry of the universe. The relation between the duration of the peak phase of a type Ia supernova’s lightcurve and its luminosity (broader is brighter) forms the cornerstone of this measurement, yet it is a purely empirical relation. In this paper we show that the relation is a natural conseque...

Classical novae are dramatic stellar explosions that take place in the accreted envelopes of white dwarfs in close binary systems. These unique cataclysmic events constitute a crucible where different scientific disciplines merge, including astrophysics, nuclear and atomic physics, cosmochemistry, high-energy physics or computer science. In this paper, we will focus on the nucleosynthesis accom...

Forty strains of Gram-positive, aerobic, heterotrophic bacteria isolated from saturated subsurface lacustrine, paleosol and fluvial sediments at the US Department of Energy's Hanford Site in south central Washington State were characterized by phylogenetic analysis of 16S rRNA gene sequences and by determination of selected morphological, physiological and biochemical traits. Phylogenetic analy...
