The intricate motions and complex vortical structures generated by the interaction between fluids solids are visually fascinating. However, reproducing such a two-way coupling thin objects turbulent numerically is notoriously challenging computationally costly: existing approaches as cut-cell or immersed-boundary methods have difficulty achieving physical accuracy, even visual plausibility, of ...

Coupling of chemistry and mechanics causes large stresses deterioration in battery active particles, which undergo a phase change. The Cahn–Hilliard approach coupled to deformations provides framework theoretically investigate the underlying physics. However, solving this model is computationally expensive, so that current application limited. In article, thermodynamically consistent phase-fiel...

We study rapidity gaps between jets in pp̄ collisions at the Tevatron by a novel solution of the nonforward BFKL equation including nonleading effects through the consistency constraint and running coupling. Results differ from earlier calculations based on the asymptotic Mueller-Tang formula, but agree with D0 data when including full event simulation using PYTHIA to model the gap survival prob...

We study analytically the effect of a constant magnetic field on the dynamics of a two dimensional Josephson array. The magnetic field induces spatially dependent states and coupling between rows, even in the absence of an external load. Numerical simulations support these conclusions.

The single-particle and collective dynamical properties of liquid lithium have been evaluated at several thermodynamic states near the triple point. This is performed within the framework of mode-coupling theory, using a self-consistent scheme which, starting from the known static structure of the liquid , allows the theoretical calculation of several dynamical properties. Special attention is ...

To test whether the known connectivies of neurons in the lamprey spinal cord are sufficient to account for locomotor rhythmogenesis, a CCconnectionist" neural network simulation was done using identical cells connected according to experimentally established patterns. It was demonstrated that the network oscillates in a stable manner with the same phase relationships among the neurons as observ...

A study of the capacity of multiple element antenna systems is presented, with particular emphasis on the effect that mutual coupling between the antenna elements has on the capacity. The results presented here shows, contrary to some earlier claims, that correlation between different channel coefficients as a function of antenna spacing, can in fact decrease when the mutual coupling effect is ...

We study gravitational collapse of a spherically symmetric scalar field in Einstein-aether theory (general relativity coupled to a dynamical unit timelike vector field). The initial value formulation is developed, and numerical simulations are performed. The collapse produces regular, stationary black holes, as long as the aether coupling constants are not too large. For larger couplings a fini...
