By means of critical behaviors of the dynamical fermion mass in four-fermion interaction models, we have shown by explicit calculations that when T = 0 the particle density will have a discontinuous jumping across the critical chemical potential µc in 2D and 3D Gross-Neveu (GN) model and these physically explain the first order feature of corresponding symmetry restoring phase transitions. For ...

Abstract. Utilizing various gauges of the radial coordinate we give a description of static spherically symmetric space-times with point singularity at the center and vacuum outside the singularity. We show that in general relativity (GR) there exist a two-parameters family of such solutions to the Einstein equations which are physically distinguishable but only some of them describe the gravit...

The long-distance effective field theory of our Universe—the Standard Model coupled to gravity— has a unique 4D vacuum, but we show that it also has a landscape of lower-dimensional vacua, with the potential for moduli arising from vacuum and Casimir energies. For minimal Majorana neutrino masses, we find a near-continuous infinity of AdS3×S1 vacua, with circumference ∼ 20 microns and AdS3 leng...

The Quarterly Workforce Indicators (QWI) are local labor market data produced and released every quarter by the United States Census Bureau. Unlike any other local labor market series produced in the U.S. or the rest of the world, QWI measure employment flows for workers (accession and separations), jobs (creations and destructions) and earnings for demographic subgroups (age and gender), econo...

We show that the effective potential for local composite operators is a useful object in studing dynamical symmetry breaking by calculating the effective potential for the local composite operators ψ̄ψ and φ2 in the Gross– Neveu (GN) and O(N) models, respectively. Since the effective potential for local composite operators can be calculated by using the Cornwall–Jackiw– Tomboulis (CJT) effective...

In this paper we show that it is always possibk to reduce errors for some forms of inductive Inference by increasing the numller of machines involved in the inference process. Moreover, we obtain precise bounds for the number of machines required to reduce any given number of errors. The type of inference we consider here was originally defined by Barzdin [l] (called GN” inference 1, and later ...

Using a fixed-energy amplitude in Randall-Sundrum single brane scenario, we compute the Newton potential on the brane. It is shown that the correction terms to the Newton potential involve a logarithmic factor. Especially, when the distance between two point masses are very small compared to AdS radius, the contribution of KK spectrum becomes dominant compared to the usual inversely square law....

A review of the supplier choice literature revealed that the locations and financial positions of the companies are among the most important elements in the supplier selection decisions (Stadtler, 2005). Therefore, distance between buyer and potential suppliers was selected as one input variable. Number of employees is the other input variable that is used as a proxy for the financial position ...

Design, setting, participants, & measurements Renal biopsy specimens from 29 patients with ANCA-associated vasculitis diagnosed at Peking University First Hospital from January of 2008 to December of 2010 were randomly collected. Urine samples from 27 of 29 patients in active stage and 22 ANCA-associated vasculitis patients in complete remission who were independent of the above-mentioned 29 pa...
