Arrested dynamics of the dipolar hard sphere model [PDF]

Soft Matter, 2020
We report the results of molecular dynamics simulations and theoretical calculations concerning various dynamical arrest transitions in a model system consisting in N (soft core) rigid spheres interacting through a truncated dipole–dipole potential.

Tetris with Few Piece Types [PDF]

We prove NP-hardness and #P-hardness of Tetris clearing (clearing an initial board using a given sequence of pieces) with the Super Rotation System (SRS), even when the pieces are limited to any two of the seven Tetris piece types.

On the convergence of soft potential dynamics to hard sphere dynamics [PDF]

Asymptotic Analysis, 2018
We address a question raised in the work of Gallagher, Saint-Raymond and Texier [ From Newton to Boltzmann: Hard Spheres and Short-range Potentials, European Mathematical Society (EMS), Zürich, 2013] that concerns the convergence of soft potential dynamics to hard sphere dynamics.

Approximation hardness of dominating set problems in bounded degree graphs [PDF]

, 2008
We study approximation hardness of the Minimum Dominating Set problem and its variants in undirected and directed graphs. Using a similar result obtained by Trevisan for Minimum Set Cover we prove the first explicit approximation lower bounds for various

Extraction of the dynamic plastic behavior of AlON single crystals by nanoimpact

Journal of Advanced Ceramics
Investigating the dynamic mechanical behavior of single-crystal aluminum oxynitride (AlON) is fascinating and crucial for understanding material performance in relevant applications.

Wear and friction of composites of an epoxy with boron containing wastes

Polímeros, 2015
Polymer surface coatings provide superior adhesion to substrates, some flexibility and corrosion resistance. On the other hand, 400,000 ton of boron wastes are generated each year.

Dynamics of heterogeneous hard spheres in a file [PDF]

Physical Review E, 2010
Normal dynamics in a quasi-one-dimensional channel of length L (\to\infty) of N hard spheres are analyzed. The spheres are heterogeneous: each has a diffusion coefficient D that is drawn from a probability density function (PDF), W D^(-γ), for small D, where 0\leqγ<1.
