The giant plasticity of [Formula: see text]He crystals has been explained as a consequence of the large mobility of their dislocations. Thus, the mechanical properties of dislocation free crystals should be quite different from those of usual ones. In 1996-1998, Ruutu et al. published crystal growth studies showing that, in their helium 4 crystals, the density of screw dislocations along the c-...

The goal of this paper is to investigate the optimality [Formula: see text]-dimensional rock-salt structure, i.e. cubic lattice text] volume with an alternation charges at points, among periodic distributions and structures. We assume that are interacting through two types radially symmetric interaction potentials, according their signs. first restrict our study class orthorhombic lattices. pro...

INTRODUCTION Although continuing medical education (CME) presentations are common across health professions, it is unknown whether slide design is independently associated with audience evaluations of the speaker. Based on the conceptual framework of Mayer's theory of multimedia learning, this study aimed to determine whether image use and text density in presentation slides are associated with...

Instance selection techniques have received great attention in the literature, since they are very useful to identify a subset of instances (textual documents) that adequately represents the knowledge embedded in the entire text database. Most of the instance selection techniques are supervised, i.e., requires a labeled data set to define, with the help of classifiers, the separation boundaries...

We consider Friedel oscillation in the two-dimensional Dirac materials when the Fermi level is near the van Hove singularity. Twisted graphene bilayer and the surface state of topological crystalline insulator are the representative materials which show low-energy saddle points that are feasible to probe by gating. We approximate the Fermi surface near saddle point with a hyperbola and calculat...

text classification is an important research field in information retrieval and text mining. the main task in text classification is to assign text documents in predefined categories based on documents’ contents and labeled-training samples. since word detection is a difficult and time consuming task in persian language, bayesian text classifier is an appropriate approach to deal with different...

Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...

It has long been known that the addition of small quantities (``doping'') so-called reactive elements (REs) such as Y, Zr, and Hf to high-temperature ${\text{Al}}_{2}{\text{O}}_{3}$ scale-forming alloys improves oxidation resistance. The presence at grain boundaries lowers growth rate $\ensuremath{\alpha}\text{\ensuremath{-}}{\text{Al}}_{2}{\text{O}}_{3}$ scales, but cause reduced scale kinetic...

Prior papers have presented a fusion framework called stream fusion for removing intermediate data structures from both lists and arrays in Haskell. Stream fusion is unique in using an explicit datatype to accomplish fusion. We demonstrate how this can be exploited in the creation of a new Haskell string representation Text, which achieves better performance and data density than String . Text ...
