Realistic Earth escape strategies for solar sailing [PDF]
With growing interest in solar sailing comes the requirement to provide a basis for future detailed planetary escape mission analysis by drawing together prior work, clarifying and explaining previously anomalies.

RNA interference reveals the escape response mechanism of Paramecium to mechanical stimulation
In Paramecium, a mechanical stimulus applied to the posterior portion of the cell causes a transient increase in membrane permeability to potassium ions, transiently rendering the membrane in a hyperpolarized state.

Neural events underlying escape swimming behaviour in the squat lobster 'Galathea strigosa' (Crustacea, Anomura) [PDF]
1. The anatomy and physiology of escape swimming behaviour in the squat lobster, Galathea strigosa, have been investigated and the results discussed in the context of comparative mechanisms of escape in rela~ed species. 2.

KINETICS OF A BINARY MIXTURE DECOMPOSITION IN RELATIONTO THE EFFECTS ON OIL RESERVOIR
The kinetic constants of the decomposition reaction of an aqueous solution of a binary mixture used for thermal-pressure induced impact on the bottomhole zone during stimulation of oil inflow are determined.

Non-equilibrium stochastic dynamics of open ion channels [PDF]
We present and discuss a modified version of reaction rate theory (RRT) to describe the passage of a positive ion through a biological ion channel. It takes explicit account of the non-equilibrium nature of the permeation process. Unlike traditional RRT,

Thermal tolerance windows are key indicators of the range of temperatures tolerated by animals and therefore, a measure of resilience to climate change.

Full distribution of first exit times in the narrow escape problem
In the scenario of the narrow escape problem (NEP) a particle diffuses in a finite container and eventually leaves it through a small ‘escape window’ in the otherwise impermeable boundary, once it arrives to this window and crosses an entropic barrier at

Prepontine non-giant neurons drive flexible escape behavior in zebrafish.
Many species execute ballistic escape reactions to avoid imminent danger. Despite fast reaction times, responses are often highly regulated, reflecting a trade-off between costly motor actions and perceived threat level.

De Novo generation of escape Variant-specific CD8+ T-Cell responses following Cytotoxic T-Lymphocyte escape in chronic Human Immunodeficiency Virus Type 1 Infection [PDF]
Human immunodeficiency virus type 1 (HIV-1) evades CD8+ T-cell responses through mutations within targeted epitopes, but little is known regarding its ability to generate de novo CD8+ T-cell responses to such mutants.
