BACKGROUND The effect of television viewing (TVV) with and without advertisements (ads) on energy intake is unclear. OBJECTIVE The objectives were to test 1) the effect of TVV, with and without ads, on energy intake compared with a control and reading condition and 2) the association of distractibility and memory for ads with energy intake and body weight. DESIGN Forty-eight (26 female) adu...
BACKGROUND Despite increasing use of assistive devices (ADs) by physically disabled (PD) children, the use rate, number, effects and related services have seldom been studied. Understanding AD utilization is helpful in improving the related services. This study describes the usage of ADs by children with physical disabilities (PDs). METHODS This regional survey enrolled children with PDs. The...
In recent years, there has been an increasing worldwide interest in accelerator driven systems (ADS) due to their perceived superior safety characteristics and their potential for burning actinides and long-lived fission products. Indian interest in ADS has an additional dimension, which is related to our planned large-scale thorium utilization for future nuclear energy generation. The physics ...
Autoimmune diseases (ADs) represent a diverse collection of diseases in terms of their demographic profile and primary clinical manifestations. The commonality between them however, is the damage to tissues and organs that arises from the response to self-antigens. The presence of shared pathophysiological mechanisms within ADs has stimulated searches for common genetic roots to these diseases....
OBJECTIVES We used a validated copy test method to examine the effectiveness of 8 types of antismoking advertisements representing health, counterindustry, and industry approaches. We tested the hypothesis that health ads about tobacco victims can lower most adolescents' intent to smoke if the ads elicit disgust and anti-industry feelings rather than fear. We hypothesized null effects for adole...
The class of ads modules with the SIP (briefly, $SA$-modules) is studied. Various conditions for a module to be $SA$-module are given. It is proved that for a quasi-continuous module $M$, $M$ is a UC-module if and only if $M$ is an $SA$-module. Also, it is proved that the direct sum of two $SA$-modules as $R$-modules is an $SA$-module when $R$ is the sum of the annihilators of thes...
The AdS/CFT conjecture relates quantum gravity on Anti-de Sitter (AdS) space to a conformal field theory (CFT) defined on the spacetime boundary. We interpret the CFT in terms of natural analogues of the bulk S-matrix. Our first approach finds the bulk S-matrix as a limit of scattering from an AdS bubble immersed in a space admitting asymptotic states. Next, we show how the periodicity of geode...
Two kinds of realizations of symmetry on classical domains or the Euclidean version of AdS space are used to study AdS/CFT correspondence. Mass of free particles is defined as an AdS group invariant, the Klein-Gordon and Dirac equations for relativistic particles in the AdS space are set up as a simple mimic in the case of Minkowskian space. The bulk-boundary propagator on the AdS space is give...

This work explores the celebrated AdS/CFT correspondence [1] in the regime of high energy scattering in Anti–de Sitter (AdS) spacetime. In particular, we develop the eikonal approximation to high energy scattering in AdS and explore its consequences for the dual Conformal Field Theory (CFT). Using position space Feynman rules, we rederive the eikonal approximation for high energy scattering in ...
