BACKGROUND During menopause, the decrease of estrogenic secretion induces the disruption of skin functioning, thus causing the decline in skin elasticity characteristic of skin aging. The purpose of this study was to evaluate in postmenopausal women the effect of daily consumption and/or application of argan oil on skin elasticity. MATERIALS AND METHODS Sixty postmenopausal women consumed but...

Previous work on the angular momentum balance and meridional circulation of the solar convective zone (SCZ) generally consists either of semianalytic approaches in which a simple turbulence model is adopted, or full direct numerical simulation (DNS) of the hydrodynamics or magnetohydrodynamics (MHD). In both instances the inclusion of magnetic fields has been troublesome. Also, both approaches ...

Robust FETI-DP methods for heterogeneous, linear elasticity problems in three dimensions were developed and analyzed in Klawonn and Widlund [2004]. For homogeneous problems or materials with only small jumps in the Young moduli, the primal constraints can be chosen as edge averages of the displacement components over well selected edges; see Klawonn and Widlund [2004] and for numerical experime...

We explore extended B-splines as a stable basis for isogeometric analysis with trimmed parameter spaces. The stabilization is accomplished by an appropriate substitution of Bsplines that may lead to ill-conditioned system matrices. The construction for non-uniform knot vectors is presented. The properties of extended B-splines are examined in the context of interpolation, potential, and linear ...

The goal of this essay is to examine estimates of individual bank X-efficiency across time. First, we estimate a translog flexible function specification of bank efficiency during the period 1988-1997. Then, we estimate a time-series/cross-sectional model with independent variables that reflect business cycle and monetary policy conditions that may affect bank performance. Like Calomiris and Ma...

This paper investigates the UK wage curve using longitudinal micro data drawn from the first eight waves of the British Household Panel Survey (BHPS). We estimate a fixed-effects model that controls for observed and unobserved individual-specific heterogeneity. Our results suggest that there is evidence of a negative relationship in wage-unemployment space. The estimated unemployment elasticity...

M literature has long recognized that brand price elasticity need not be monotonic and symmetric, but has yet to provide generalizable market-level insights on threshold-based price elasticity, asymmetric thresholds, and the sign and magnitude of elasticity transitions. This paper introduces smooth transition regression models to study threshold-based price elasticity of the top 4 brands across...
