The scenario of brane inflation without using the conventional slow-roll approximations has been investigated. Based on the mechanism of generating the curvature perturbations at the end of inflation, a new brane inflation paradigm was developed. The conditions for making a sufficiently large enough number of e-foldings and for generating the curvature perturbations without producing dangerous relics were also examined. Benefits of our scenario are subsequently discussed in detail.

Vasomotor effects of 5-hydroxytryptamine, histamine, angiotensin II, acetylcholine, noradrenaline, and bradykinin on the cerebral artery of bottlenose dolphin (Tursiops truncatus)

The irreversible changes in electrical resistance (time-decay) of gold films evaporated at room temperature were measured as a function of time to know the mechanism of the forming process of evaporated films. An experimental formula was derived for the change in electrical resistance. For the initial portions of the decay curves, the decay rate d R/d t was found to be proportional to (R-R ∞) n , where n was almost independent of the evaporation rate. When the film thickness is 140 A±10 A, n is about 6.0 and it increases with increasing thickness. The mechanism of decay is understood as annihilation process of distortions generated in films during deposition. It is found that recombination theory and diffusion theory already proposed to explain the phenomenon are unsuitable to interprete the decay of the very initial stage of the film formation. It seems that much more complicated processes take place at this stage.
