Abstract Large defects are the main factor leading to degradation of material properties under irradiation environments. It is commonly assumed that large mainly formed through cluster growth continuous irradiations. Besides this mechanism, recent experiments and simulations show sometimes an individual ion can also directly create a defect. Here we report novel mechanism for formation defects, as discovered by our Molecular Dynamics (MD) collision cascades in hcp Zirconium (Zr):...
The mutual transformations among the four typical divacancy defects induced by a high-energy pulse were studied via molecular dynamics simulation. Our study revealed all six possible and found that transformed absorbing energy to overcome barrier with bonding, debonding, bond rotations. reversibility of defect was also investigated potential analysis. difference greatly influence transformation reversibility. direct path irreversible if too large. We correlation between probability input...
Single-atom catalysts (SACs) represent the ultimate goal of nanocatalysis fields. However, complex synthesis processes and pyrolysis inactivation problems are two main challenges that plague development SACs. In this work, we propose ultralow-energy ion-implantation (ULEII) method could be utilized to simply efficiently synthesize stable Our simulation results Pt-ion implantation into graphene indicate total doping efficiency, including direct displacement indirect trap doping, can...
In this paper, we introduce and study $p$-uniform subsmoothness of a collection infinitely many closed sets in Banach space. Using variational analysis techniques, mainly linear regularity for satisfying subsmoothness. The necessary or/and sufficient conditions on the are obtained case. particular, extend characterizations convex to nonconvex setting.
We introduce a stochastic model in which adjacent planar regions $A, B$ merge stochastically at some rate $\lambda(A,B)$, and observe analogies with the well-studied topics of mean-field coagulation bond percolation. Do infinite appear finite time? give simple condition on $\lambda$ for this {\em hegemony} property to hold, another it not but there is large gap between these conditions, includes case $\lambda(A,B) \equiv 1$. For case, non-rigorous analytic argument simulations suggest hegemony.

This paper is devoted to primal conditions of error bounds for a general function. In terms Bouligand tangent cones, lower Hadamard directional derivatives and the Hausdorff-Pompeiu excess subsets, we provide several necessary and/or sufficient with mild assumptions. Then use these results characterize composite-convex functions (i.e. composition convex function continuously differentiable mapping). It proved that characterization can be established via if mapping metrically regular at given...
This article is devoted to the stability of error bounds (local and global) for semi-infinite convex constraint systems in Banach spaces. We provide primal characterizations local global when are subject small perturbations. These given terms directional derivatives functions that enter into definition these systems. It proved essentially equivalent verifying optimal values several minimax problems, defined defining systems, outside some neighborhood zero. Moreover, such only requires all...
Abstract For a group G and $m\ge 1$ , let $G^m$ denote the subgroup generated by elements $g^m$ where g runs through . The subgroups not of form are nonpower We classify groups with at most nine subgroups.
For a group G and positive interger m, Gm denotes the subgroup generated by elements gm where g runs through G. The subgroups not of form are called nonpower subgroups. We extend classification groups with few from at most 9 to 13
Error bounds are central objects in optimization theory and its applications. They were for a long time restricted only to the before becoming over course of field itself. This paper is devoted study error general inequality defined by proper lower semicontinuous function on an Asplund space. Even though results dual characterization (if one drops convexity assumption) may not be valid, several necessary conditions still obtained terms Fr\'echet/Mordukhovich subdifferentials concerned at...
