DOI: 10.1002/mma.5598
Abstract: We deal with the stationary acoustic waves propagating in a cluster of small particles enjoying high contrasts. Such contrasts allow the appearance of (complex valued) resonances that are close to the real line as the… read more here.

DOI: 10.1007/s10035-024-01476-6
Abstract: We numerically examine binary-sized granular mixtures confined between two parallel walls subjected to vertical vibration using the discrete element method. For a size ratio of 3 between large and small particles, we study the structure… read more here.

DOI: 10.1080/00150193.2017.1367214
Abstract: ABSTRACT In this article, the experiments on growth of small ferroelectric-salt particles from their aqueous solutions are analyzed with the help of the Landau-Ginzburg-Devonshire theory of phase transitions. Contrary to the most common trend, the… read more here.

DOI: 10.1093/mnras/stx3023
Abstract: White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and evolving transits in the star's light curve. Here, we… read more here.

DOI: 10.1103/physreve.110.015101
Abstract: We experimentally verify the "phase locking model," which describes the formation of one-dimensional coherent structures by low-Stokes-number particles as proposed by Pushkin et al. [Phys. Rev. Lett. 106, 234501 (2011)0031-900710.1103/PhysRevLett.106.234501] in thermocapillary liquid bridges: When the… read more here.
