We review the renormalization group (RG) method for interacting fermions, building off typical φ theory to account for the presence of a Fermi surface. A few geometries and the general procedure are briefly discussed. The method is illustrated with a model of two Fermi circles with different spin components and momenta, which can describe experiments with interacting fermions. General results o...

In this paper we derive a simple parametrization of the cycling method developed by us in our earlier work. The new method, called renormalization group (RG) mapping, consists of a series of carefully tuned APEsmearing steps. We study the relation between cycling and RG mapping. We also investigate in detail how smooth instantons and instanton-antiinstanton pairs behave under the RG mapping tra...

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...

Using the recent four-loop calculations of the QCD β-function and the three-loop matching coefficients we study the induced errors in αs(mZ) obtained from αs(mτ ) due to the evolution procedure. We show that, when consistent matching and running is used at this order, these errors are pushed below 0.0005 in αs(mZ). The beta function and the quark mass anomalous dimension govern the evolution of...

abstract this study investigates the impact of housing and non- housing investment on the iran's gross domestic production (gdp) using quarterly data from 1370-1 to 1386-4. considering that iran has an open economy and that the net export plays an important role in gdp fluctuations, this research focuses on the difference between the effects of residential and non-residential investment in open...

There has been significant increase in penetration of renewable generation (RG) sources all over the world. Localized concentration of many such generators could initiate a cascade tripping sequence that might threaten the stability of the entire system. Understanding the impact of cascade tripping process would help the system planner identify trip sequences that must be blocked in order to in...

This paper presents and compares WordNetbased and distributional similarity approaches. The strengths and weaknesses of each approach regarding similarity and relatedness tasks are discussed, and a combination is presented. Each of our methods independently provide the best results in their class on the RG and WordSim353 datasets, and a supervised combination of them yields the best published r...

The aim is to develop an application which will provide the functionality to manage regular operations of the residential apartments. The main objective of the project is to develop the application software for the different apartments which will be useful for all of them. Working efforts of the members and the managing body of the apartment will be reduced to maintain the society. It mainly su...

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...

Identifying users' frequent behaviors is considered a key step to achieving real, intelligent environments that support people in their daily lives. These patterns can be used in many different applications. An algorithm that compares current behaviors of users with previously discovered frequent behaviors has been developed. In addition, it identifies the differences between both behaviors. Id...
