P. The thinness coldness galactic disks can be used to set stringent limits on current rate infall satellite systems onto spiral galaxies. After reviewing literature concerning numerical results, we develop analytical arguments which confirm considerably extend prior work. For infalling...
We present a three-dimensional compressible magneto-hydrodynamics (MHD) simulation of the three coronal mass ejections (CMEs) 2000 November 24, originating from NOAA active region 9236. These ejections, with velocities around 1200 km s-1 and associated X-class flares, erupted Sun in period about 16.5 hr. In our simulation, magnetic field is reconstructed MDI magnetogram data, steady-state solar wind based on varying polytropic index model, are initiated using out-of-equilibrium...
Abstract We model voting behaviour in the multi-group setting of a two-tier system using sequences de Finetti measures. Our is defined by representation probability measure (i.e. as mixture conditionally independent measures) describing behaviour. The describes interaction between voters and possible outside influences on them. assume that for each population size there (potentially) different measure, grows, sequence measures converges weakly to Dirac at origin, representing tendency toward...
Abstract It is now well established that the ionosphere, because it acts as a significant source of plasma, plays critical role in ring current dynamics. However, deposits energy into inverse may also be true: can play dynamics ionospheric outflow. This study uses set coupled, first‐principles‐based numerical models to test dependence outflow on current‐driven region 2 field‐aligned currents (FACs). A moderate magnetospheric storm event modeled with Space Weather Modeling Framework using...
Abstract Using a two‐way coupled magnetohydrodynamics with embedded kinetic physics model, we perform substorm event simulation to study electron velocity distribution functions (VDFs) evolution associated Bursty Bulk Flows (BBFs). The was observed by Magnetospheric Multiscale satellite on 16 May 2017. simulated BBF macroscopic characteristics and VDFs agree well observations. from the tail its dipolarization front (DF) during earthward propagation are revealed they show clear energization...
We analyse a generalisation of the Galam model binary opinion dynamics in which iterative discussions take place local groups individuals and study effects random deviations from group majority. The probability deviation or flip depends on magnitude Depending values parameters give deviation, shows wide variety behaviour. are interested characteristics when themselves randomly selected, following some distribution. Examples these whether large majorities ties attractors repulsors, number...
For a domain D, pointpand function f the integral M (D; p)= Z D f(px)dx is called moment of with respect to p taken f. Herepx denotes distance x p. The Moment Theorem László Fejes Tóth states following: Let H be convex polygon in E 2 at most six sides and non-increasing defined for non-negative reals. p1;pn distinct points let Di Dirichlet cell pi relative H. Then we have n P i=1 (Di; pi) 5 nM (Hn; o); where Hn regular hexagon area a(Hn)=a(H)=n centered o. In paper stability criterion established.
