The bound state structure and dynamics for an atom trap formed from the whispering gallery modes ~WGMs! of a dielectric microsphere are investigated. The coupling of the quantized internal and external atomic degrees of freedom plays a fundamental role in the quantum dynamics of this atom gallery. The radiative processes for a cold atom near a microsphere are modified due to the special symmetr...

This paper presents a recent study focusing on how Internet users introduce themselves publicly in cyberspace through personal web pages, personal diaries and web sites where they can search for relationships, love, or friendship. Our goal is to analyse the extent to which personal relationships are considered from a marketing standpoint, and in what sense we can talk about how personal relatio...

abstract aeration is conducted on the perennial grasses such as lawns to reduce soil compaction and enhances the growth as well as improves soil infiltration. in order to evaluate the effects of aeration and topdressing on water infiltration phenomenon in a perennial lawn a factorial experiment in a completely randomized design was conducted in the city of isfahan in june 2009. aeration, as the...

Given a simple polygon P on n vertices, two points x, y in P are said to be visible to each other if the line segment between x and y is contained in P. The point-guard art gallery problem asks for a minimum set S such that every point in P is visible from a point in S. Assuming integer coordinates and a special general position assumption, we present the first O(log OPT)-approximation algorith...

PURPOSE OF STUDY Dementia refers to a variety of diseases that are characterized by cognitive difficulties and an overall decline in daily living skills. Psychologically informed arts and health programs may be particularly beneficial ways of improving the lives of people with dementia and their caregivers. This study sought to better understand how programs at contemporary and traditional art ...

This paper addresses the estimation of a small gallery size that can generate the optimal error estimate and its confidence on a large population (relative to the size of the gallery) which is one of the fundamental problems encountered in performance prediction for object recognition. It uses a generalized two-dimensional prediction model that combines a hypergeometric probability distribution...

Context-awareness can greatly enhance the usability of mobile devices by making it possible for users to continue with other activities without having to pay too much attention to the device. At the same time contextaware applications can provide timely support for user activities by responding to changes in the user’s state and acting accordingly. We describe our work on developing a generic c...

Results are presented for the largest experimental study to date that investigates the comparison and combination of 2D and 3D face recognition. To our knowledge, this is also the only such study to incorporate significant time lapse between gallery and probe image acquisition, and to look at the effect of depth resolution. Recognition results are obtained in (1) single gallery and a single pro...

We theoretically and experimentally investigate the multipolar hybrid plasmon-photon modes supported by a dielectric-metal core-shell resonator consisting of a dielectric core wrapped by a thin silver shell and the whispering-gallery modes in its pure dielectric counterpart (the dielectric sphere with the same size). We theoretically demonstrate that in a certain wavelength range the achievable...

The intercalation of tetrabutylammonium (TBA) cations into graphite by cation exchange from a sodium-ethylenediamine graphite intercalation compound yields a single-phase first-stage product, C(44)TBA, with a gallery expansion of 0.47 nm. The gallery dimension requires an anisotropic "flattened" cation conformation.
