TL;DR: Grain boundary structures, energies, and dynamics of binary two-dimensional materials are investigated through the development of a phase field crystal model that is parametrized to match the ordering, symmetry, energy, and length scales of hexagonal boron nitride.

TL;DR: This work examines a type of nonpotential active system, focusing on effects of coupling and competition between chiral particle self-propulsion and self-spinning, which leads to the transition between three bulk dynamical regimes dominated by collective translative motion, spinning-induced structural arrest, and dynamical frustration.

TL;DR: The authors show that in the context of ultrasound tomography, it is possible to construct reflection images of the breast that correct for inhomogeneous distributions of both sound speed and attenuation.

TL;DR: In this article, the authors consider dislocation-free, coherent, growing alloy films which could exhibit a morphological instability without nucleation and investigate such strained films by developing a nonequilibrium continuum model and by performing a linear stability analysis.
