Fast kinetic Monte Carlo simulation of strained heteroepitaxy in three dimensions

Accelerated algorithms for simulating the morphological evolution of strained heteroeptiaxy based on a ball and spring lattice model in three dimensions are explained. We derive exact Green's function formalisms for boundary values in the associated lattice elasticity problems. The computational efficiency is further enhanced by using a superparticle surface coarsening approximation. Atomic hoppings simulating surface diffusion are sampled using a multi-step acceptance-rejection algorithm. It utilizes quick estimates of the atomic elastic energies from extensively tabulated values modulated by the local strain. A parameter controls the compromise between accuracy and efficiency of the acceptance-rejection algorithm.Comment: 10 pages, 4 figures, submitted to Proceedings of Barrett Lectures 2007, Journal of Scientific Computin

Introduction to Interpersonal Acceptance-Rejection Theory (IPARTheory) and Evidence

Interpersonal acceptance-rejection theory (IPARTheory) is an evidence-based theory of socialization and lifespan development. It is composed of three subtheories, each of which deals with a separate but interrelated set of issues. IPARTheory’s personality subtheory – which is the most highly developed component of the theory – deals primarily with the pancultural nature and effects of interpersonal acceptance and rejection. Coping subtheory explores the fact that some individuals are better able to cope with experiences of perceived rejection than are other individuals. Finally, IPARTheory’s sociocultural systems subtheory attempts to predict and explain major causes and sociocultural correlates of interpersonal acceptance-rejection worldwide. Empirical evidence overwhelmingly supports the theory’s major postulates and predictions, especially postulates and predictions in personality subtheory. Emerging evidence about the neurobiological and biochemical risks posed for the development, structure, and function of the human brain are beginning to help explain why these postulates and predictions are so consistently confirmed panculturally

Penerimaan Orang Tua Menentukan Lingkungan Pengasuhan Keluarga Dengan Anak Remaja Di Wilayah Suburban

: The aim of this study was to analyze the relationship between parental acceptance-rejection and parenting environment in families with adolescence in the suburban area. This study involved 50 families randomly selected. Data were collected by using questionnaire and structured interview. Parental acceptance-rejection was measured by Parental Acceptance Rejection Questionnaire (PARQ) and parental environment was measured by Home Observation and Measurement of the Environment type Early Adolescent (HOME-EA). The result showed that there was a significant relationship between age of adolescence and parents' aggressive behavior. Meanwhile, longer mothers' education was significantly correlated with better parenting environment of the family. The results also revealed that there was a significant correlation between parental acceptance-rejection and parenting environment in families with adolescence in the suburban area

Rejection, denial and the democratic primaries

Starting from the case of insurance claims, I investigate the dynamics of acceptance, rejection and denial. I show that disagreement can be more varied than one might think. I illustrate this by looking at the Warren/Sanders controversy in the 2020 democratic primaries and at religious agnosticism

Fermions as Global Correction: the QCD Case

It is widely believed that the fermion determinant cannot be treated in global acceptance-rejection steps of gauge link configurations that differ in a large fraction of the links. However, for exact factorizations of the determinant that separate the ultraviolet from the infrared modes of the Dirac operator it is known that the latter show less variation under changes of the gauge field compared to the former. Using a factorization based on recursive domain decomposition allows for a hierarchical algorithm that starts with pure gauge updates of the links within the domains and ends after a number of filters with a global acceptance-rejection step. Ratios of determinants have to be treated stochastically and we construct techniques to reduce the noise. We find that the global acceptance rate is high on moderate lattice sizes and demonstrate the effectiveness of the hierarchical filter.Comment: 36 pages, 9 figures; improved version to be published in Comput.Phys.Commun., new results for the topological charge presented in Figure
