Activation of the stress response evokes a cascade of physiological reactions that may be detrimental when repeated or chronic, and when triggered after exposure to psychological/emotional stressors. Investigation of the physiological mechanisms responsible for the health damaging effects requires animal paradigms that repeatedly evoke a response to psychological/emotional stressors. To this en...
The Kerr/CFT correspondence is a holographic duality between a two dimensional chiral conformal field theory (CFT) and the very near horizon limit of an extremal black hole, which includes an AdS2 structure. To understand the dual chiral CFT2, we apply the Kerr/CFT correspondence to a certain class of black holes embedded in string theory, which include the D1-D5-P and the BMPV black holes, and...
It is now well established that there exists the correspondence between the Supergravity theory on Anti-deSitter spacetime (AdS) and the Large N limit of Super Yang-Mills CFT. In the case of 3-d BTZ black hole , Strominger has given a simple statistical derivation of the Bekenstein-Hawking entropy via Cardy’s formula. This is an important check for the correspondence. The AdS/CFT correspondence...
In severe and rapidly increasing jaundice, the use of intensive phototherapy provides greater effectiveness and a faster decrement in bilirubin levels compared to conventional phototherapy. The aim of this study was to compare the effectiveness of two types of intensive phototherapy: intensive compact fluorescent tube (CFT) and intensive light-emitting diode (LED) phototherapy. Forty-three infa...
We use the AdS/CFT correspondence to calculate CFT correlation functions of vector and spinor fields. The connection between the AdS and boundary fields is properly treated via a Dirichlet boundary value problem.
Although tuberculin skin testing has been a hallmark of bovine tuberculosis eradication campaigns, it lacks sensitivity, can be confounded by exposure to nontuberculous mycobacteria, and cannot be repeated for 60 days due to desensitization. To overcome these difficulties, an effective whole-blood cellular immunoassay for bovine gamma interferon (IFN-gamma) has been developed. The IFN-gamma tes...
Counterfactual thinking (CFT) is a type of conditional reasoning involving mental representations of alternatives to past factual events that previous preliminary research has suggested to be impaired in schizophrenia. However, despite the potential impact of these deficits on the functional outcome of these patients, studies examining the role of CFT in this disorder are still few in number. T...
We discuss the relationship between the bulk-boundary correspondence in Rehren’s algebraic holography (and in other ‘fixed-background’, QFT-based, approaches to holography) and in mainstream string-theoretic ‘Maldacena AdS/CFT’. Especially, we contrast the understanding of black-hole entropy from the point of view of QFT in curved spacetime – in the framework of ’t Hooft’s ‘brick wall’ model – ...
buckling instability is the most important factor at columns failune. icauses large deflection and mostly is analysed by first yield criterion. due fo some difficulties in application of the criterion, soecially in inelastic columns, a new method, namely geometric criterion is introduced in this paper to improve the buckling analysis of real columns. in this research project a number box- secti...
