Electron Acceleration at a Low-mach-number Perpendicular Collisionless Shock
A full particle simulation study is carried out on the electron acceleration at a collisionless, relatively low Alfven Mach number (MA = 5), perpendicular shock. Recent self-consistent hybrid shock simulations have demonstrated that the shock front of perpendicular shocks has a dynamic rippled character along the shock surface of low-Mach-number perpendicular shocks. In this paper, the effect o...
متن کاملPull-in behavior of a bio-mass sensor based on an electrostatically actuated cantilevered CNT with consideration of rippling effect
This paper examines the pull-in behavior of a bio-mass sensor with a cantilevered CNT actuated electrostatically by considering rippling deformation. Although this phenomenon can remarkably change the behavior of CNT, its effect on the performance of a CNT-based mass sensor has not been investigated thus far. This investigation is based on modified Euler-Bernoulli beam theory and rippling effec...
متن کاملThe properties and causes of rippling in quasi-perpendicular collisionless shock fronts
The overall structure of quasi-perpendicular, high Mach number collisionless shocks is controlled to a large extent by ion reflection at the shock ramp. Departure from a strictly one-dimensional structure is indicated by simulation results showing that the surface of such shocks is rippled, with variations in the density and all field components. We present a detailed analysis of these shock ri...
متن کاملUpstream whistlers generated by protons reflected from a quasi-perpendicular shock
Numerical simulations of collisionless supercritical quasi-perpendicular shocks suggest that the upstream whistlers may be generated near the shock by the reflected protons which gyrate back to the shock. We investigate in detail results of hybrid simulations and a linear theory for a gyrotropic gyrating beam in a Maxwellian plasma, and we compare their outcomes. We find good agreement between ...
متن کاملSpeculative Oil Demand and Crude Oil Price Dynamics: A TVP-VAR Approach
Significant decline in the slope of short-term oil supply and demand curves, along with the meaningful change in the degree of risk aversion in arbitrageurs encouraged us to test the time-varying effects of speculative demand on crude oil price dynamics over the period 1985-2016. Using a time-varying parameter vector autoregressive (TVP-VAR) model – with structural shocks identified by Killian ...
