We studied 129 female rhythmic gymnasts (RG) and 142 female artistic gymnasts (AG) who participated in the 1999 Gymnastics World Championship for RG in Osaka, Japan, and the 1999 and 2001 Gymnastics World Championships for AG in Tianjin, China (n = 48), and Ghent, Belgium (n = 94), respectively. RG were taller than average, with a mean height SD score above the 50th percentile, whereas AG were ...

We demonstrated previously that ginsenoside Rg(3) (Rg(3)), an active ingredient of Panax ginseng, inhibits brain-type Na(+) channel activity. In this study, we sought to elucidate the molecular mechanisms underlying Rg(3)-induced Na(+) channel inhibition. We used the two-microelectrode voltage-clamp technique to investigate the effect of Rg(3) on Na(+) currents (I(Na)) in Xenopus laevis oocytes...

In earlier work, the evolution operator for exact RG equation was mapped to a field theory in Euclidean AdS. This gives simple way of understanding AdS/CFT. We explore aspects this map by studying example Schrödinger free particle with time-dependent mass. is an analytic continuation ERG like equation. show instance that it can be harmonic oscillator. same techniques lead dS/CFT too.

The second derivatives of prepotential with respect to Whitham time-variables in the Seiberg-Witten theory are expressed in terms of Riemann theta-functions. These formulas give a direct transcendental generalization of algebraic ones for the Kontsevich matrix model. In particular case they provide an explicit derivation of the renormalization group (RG) equation proposed recently in papers on ...

Renormalization group flows of quiver gauge theories play a central role in determining the low-energy properties of string vacua. We demonstrate that useful predictions about the RG dynamics of a quiver gauge theory may be extracted from the global structure of its quiver diagram. For quiver theories of a certain type, we develop an efficient and practical method for determining which superpot...

We study cosmological backgrounds from the point of vue of the dS/CFT correspondence and its renormalization group flow extension. We focus on the case where gravity is coupled to a single scalar with a potential. Depending on the latter, the scalar can drive both inflation and the accelerated expansion (dS) phase in the far future. We also comment on quintessence scenarios, and flows familiar ...

RG 12525 is a new chemical entity recently evaluated for the treatment of type II diabetes. Clinical studies have previously identified the tetrazole N2-glucuronide conjugate of RG 12525 as the predominant metabolite in plasma following oral administration of RG 12525. Species differences in RG 12525 glucuronidation were first investigated with incubations of RG 12525 with rat, monkey, and huma...

Let R be a commutative ring, G a group and RG its group ring. Let φ : RG → RG denote the R-linear extension of an involution φ defined on G. An element x in RG is said to be φantisymmetric if φ(x) = −x. A characterization is given of when the φ-antisymmetric elements of RG commute. This is a completion of earlier work. keywords: Involution; group ring; antisymmetric elements. keywords: 2000 Mat...
