In the article recently published by Henderson et al. (1) from the Multiethnic Cohort Study, the authors reported significant race/ethnicity-specific hazard ratios for the timing of menopause. Natural menopause occurred earlier among Latinas and later among Japanese-American women relative to non-Latina whites. The authors further emphasized that these relations are suggestive of a heritable co...

The nonlinear dynamics of the free surface of an ideal conducting liquid in a strong external electric field is studied. It is establish that the equations of motion for such a liquid can be solved in the approximation in which the surface deviates from a plane by small angles. This makes it possible to show that on an initially smooth surface for almost any initial conditions points with an in...

We collect some arguments for treating a D-brane with overcritical electric field as a well-posed initial condition for a D-brane decay. Within the field theoretical toy model of Minahan and Zwiebach we give an estimate for the condensates of the related infinite tower of tachyonic excitations.

We study the evolution of mixed scalar as well as spinor fields within the context of the classical field theory. The initial condition problem is solved and the fields distributions, exactly accounting for the initial conditions, are obtained for both scalar and spinor fields. In the system of two coupled fields we consider the special case of the initial conditions which are rapidly oscillati...

The cosmological effects of the tachyon rolling down to its ground state are discussed by coupling a simple effective field theory for the tachyon field to Einstein gravity. As the tachyon rolls down to the minimum of its potential the universe expands. Depending upon initial conditions, the scale factor may or may not start off accelerating, but ultimately it ceases to do so and the final flat...

In a previous paper [Math. Meth. Mod. App. Sci, vol. 11, 1253-1272, 2001], the high field limit for degenerate semiconductors is analyzed by the authors. The scope of the present paper is the extention of this analysis to boundary value problems. The initial layer, modeled by a homogeneous Boltzmann equation with a frozen electric field provides an initial condition for the high field solution....

Method: Two hundred and nine patients who were diagnosed with precancerous lesions and referred to the dermatology department of Imam Reza hospital from 1997 to 2007 were studied. Study parameters included participants’ age, sex and occupation, type of precancerous skin lesion, clinicopathological type of the lesion and location. The data was collected from the patients’ records in the dermatol...

Previous studies on reaching movements have shown that people can adapt to distortions that are either visuomotor (e.g., prism glasses) or mechanical (e.g., force fields) through repetitive training. Other work has shown that these two types of adaptation may share similar neural resources. One effective test of this sharing hypothesis would be to show that one could teach one using the other. ...

The metrizability of sprays, particularly symmetric linear connections, is studied in terms of semi-basic 1-forms using the tools developed by Bucataru and Dahl in [2]. We introduce a type of metrizability in relationship with the Finsler and projective metrizability. The Lagrangian corresponding to the Finsler metrizability as well as the Bucataru–Dahl characterization of Finsler and projectiv...
