We use a time-dependent hopping expansion technique to study the non-equilibrium dynamics of strongly interacting bosons in an optical lattice in the presence of a harmonic trap characterized by a force constant K. We show that after a sudden quench of the hopping amplitude J across the superfluid (SF)-Mott insulator (MI) transition, the SF order parameter [Formula: see text] and the local dens...

this study aimed at investigating the english textese of iranian efl learners by scrutinizing the linguistic features through a qualitative design. in doing so, 700 messages were collected from 43 ma iranian efl learners of both genders. the features were categorized and analyzed calculating the frequency and percentage. the findings of the study showed that iranian efl students used different ...

A number of recent publications on small photon beam dosimetry aim at contributing to the understanding of the response of solid-state detectors in small fields. Some of them assign the difference in response to the mass density, or to the electron density, of the sensitive detector material relative to that of water. This work analyses the role of the mass and electron density ([Formula: see t...

Using transversality and a dimension reduction argument, a result of Bezdek and Kuperberg is applied to polycylinders, showing that the optimal packing density of [Formula: see text] equals [Formula: see text] for all natural numbers n.

We study equilibrium statistical mechanics of classical point counter-ions, formulated on 2D Euclidean space with logarithmic Coulomb interactions (infinite number of particles) or on the cylinder surface (finite particle numbers), in the vicinity of a single uniformly charged line (one single double layer), or between two such lines (interacting double layers). The weak-coupling Poisson-Boltzm...

The detection of outliers in text documents is a highly challenging task, primarily due to the unstructured nature and curse dimensionality. Text document refer data that deviates from found other belonging same category. Mining has wide applications various domains, including spam email identification, digital libraries, medical archives, enhancing performance web search engines, cleaning corp...

A streaming data clustering algorithm is presented building upon the density-based self-organizing stream clustering algorithm SOSTREAM. Many density-based clustering algorithms are limited by their inability to identify clusters with heterogeneous density. SOSTREAM addresses this limitation through the use of local (nearest neighbor-based) density determinations. Additionally, many stream clus...

Abstract Enhanced particle transport events are discovered and analyzed as the density limit of J-TEXT tokamak is approached. Edge shear layer collapse observed ratio Reynolds power to turbulence production decreases. Simultaneously, divergence internal energy flux (i.e. spreading) increases, indicating that triggers an outward spreading event. Studies correlations show enhanced quasi-coherent,...
