Evaporation and Accretion of Extrasolar Comets Following White Dwarf Kicks [PDF]
, 2015 Several lines of observational evidence suggest that white dwarfs receive small birth kicks due to anisotropic mass loss. If other stars possess extrasolar analogues to the Solar Oort cloud, the orbits of comets in such clouds will be scrambled by white ...

AxiomsSince the research of μ-synchronization helps to explore how complex networks (CNs) work together to produce complex behaviors, the μ-synchronization task for uncertain time-delayed CNs is studied in our work.

Standard map in magnetized relativistic systems: fixed points and regular acceleration [PDF]
, 2010 We investigate the concept of a standard map for the interaction of relativistic particles and electrostatic waves of arbitrary amplitudes, under the action of external magnetic fields.

Transition stages of Rayleigh–Taylor instability between miscible fluids [PDF]
, 2001 Direct numerical simulations (DNS) are presented of three-dimensional, Rayleigh–Taylor instability (RTI) between two incompressible, miscible fluids, with a 3:1 density ratio.

Fluctuation-Dissipation relations in Driven Granular Gases
, 2002 We study the dynamics of a 2d driven inelastic gas, by means of Direct Simulation Monte Carlo (DSMC) techniques, i.e. under the assumption of Molecular Chaos.

Three-dimensional flows around low-aspect-ratio flat-plate wings at low Reynolds numbers [PDF]
, 2009 Three-dimensional flows over impulsively translated low-aspect-ratio flat plates are investigated for Reynolds numbers of 300 and 500, with a focus on the unsteady vortex dynamics at post-stall angles of attack. Numerical simulations, validated by an oil

Beyond the Thin Lens Approximation [PDF]
, 1994 We obtain analytic formulae for the null geodesics of Friedmann-Lema\^{\i}tre-Robertson-Walker spacetimes with scalar perturbations in the longitudinal gauge.

Application of Lyapunov's Direct Method to the Existence of Integral Manifolds of Impulsive Differential Equations [PDF]
, 1996 The present paper investigates the existence of integral manifolds for impulsive differential equations with variable perturbations. By means of piecewise continuous functions which are generalizations of the classical Lyapunov’s functions, sufficient ...

Necessary conditions involving Lie brackets for impulsive optimal control problems
, 2019 We obtain higher order necessary conditions for a minimum of a Mayer optimal control problem connected with a nonlinear, control-affine system, where the controls range on an m-dimensional Euclidean space.
