We formulate a holographic Wilsonian renormalization group flow for strongly coupled systems with a gravity dual, motivated by the need to extract efficiently low energy behavior of such systems. Starting with field theories defined on a cutoff surface in a bulk spacetime, we p...

aims: drug abuse among college students continues as a major public-health concern. theory-driven research is necessary to address and find causes. the current research investigates the utility of theory of planned behavior (tpb) in designing and implementing a drug abuse educational prevention program among medical college students. methods: this quasi-experimental study was conducted among 12...

It is shown that for 2D field theories only the first order coefficient of the gravitationally dressed RG β-function is scheme independent. This is valid even for matter theories with one dimensionless coupling, where the first two coefficients of the original β-function are scheme independent.

background : drug abuse is one of the important challenges in the field of mental health and adolescence health promotion. because of the social and medical cost of drug abuse and its consequences among youth people, it is necessary to intervene effectively. this theoretical based study explained predictability of the theory of planned behaviour (tpb) on drug abuse related behaviours. methods :...

The flow equations or exact RG equations for the Higgs Top System are solved to leading order in 1/Nc. This allows to relate arbitrary bare actions with this field content continuously to effective low energy theories, and we find the flow converging towards general renormalizable models. The assumption of a bare action of the generalized Nambu-Jona-Lasinio type does not restrict the parameters...

BACKGROUND/OBJECTIVES The purpose of this investigation was to test whether the gateway hypothesis of drug initiation sequencing applies equally well to high-risk African-American and Caucasian youth. METHODS The study sample (N = 618, mean age = 15.5, SD = 1.2) represented the population of residents in the Missouri Division of Youth Services (DYS) who had initiated marijuana and nicotine us...

We study the Penrose limit of the (p, q) fivebranes supergravity background. We consider the different phases of the worldvolume field theory and their weakly coupled descriptions. In the Penrose limit we get a solvable string theory and compute the spectrum. It corresponds to states of the six-dimensional worldvolume theory with large energy and large U(1) charge. We comment on the RG behavior...

The calculation of the full (renormalized) holographic action is undertaken in general Einstein-scalar theories. The appropriate formalism is developed and the renormalized effective action is calculated up to two derivatives in the metric and scalar operators. The holographic RG equations involve a generalized Ricci flow for the space-time metric as well as the standard β-function flow for sca...
