A two-stream instability in an unmagnetized plasma is examined by a particle-in-cell simulation. Each beam initially consists of cold electrons and protons... ME Dieckmann - 《Physical Review Letters》 被引量: 45发表: 2005年 Ion Acceleration by the Relativistic Two-Stream Instability Theoretical...
a. Find the ratio of the electrostatic force to the gravitational force between two electrons. b. Will this ratio change if the two electrons are replaced by protons? If yes, find the new ratio. Two charged spheres 10 cm apart attrac...
The starting point for the selection of K− absorption processes leading to Σ0p final state is the identification of a Λ(1116) hyperon through its decay into protons and negative pions (BR = 63.8%). Proton and pion track candidates are selected via dE/dx measurement in the DC. For ea...
NMR self-diffusion and relaxation, coupled with viscosity, were used to study the properties and structure of two imidazolium-based ionic liquids, 1-ethyl-3-methylimidazolium acetate [C2MIM][OAc] and 1-ethyl-3-methylimidazolium octanoate [C2MIM][OOct]. T
limits of validity of linear and quadratic response theory calculations, and show that nonlinear screening theory already provides significant corrections in the case of protons. In contrast to the 3D situation, we find that the nonlinearly screened potential supports a bound state even in the ...
[34], so it can be speculated that the higher energy status in the overexpressing GatA recombinant strain provides more energy for the catalytic action of H+-ATPase to pump the accumulated protons out of the cell to maintain intracellular pH homeostasis and relieve acid stress [35,36]. When ...
