Scattering of e by CH Molecule over a Wide Range of Energy: A Theoretical Investigation.

The present work reports the theoretical investigation of the scattering of electrons and positrons by the ethane (C2H6) molecule over the energy range 1 eV-1 MeV. The investigation was carried out by taking into account the screening correction arising from a semiclassical analysis of the atomic geometrical overlapping of the scattering observables calculated in the independent atom approximation. The study is presented through the calculations of a broad spectrum of observable quantities, namely differential, integrated elastic, momentum transfer, viscosity, inelastic, grand total, and total ionization cross-sections and the Sherman functions.

Early-life Chronic Stressors, Rumination, and the Onset of Vulvodynia.

Introduction: Vulvodynia is a debilitating, chronic vulvar pain condition. Community-based case-control studies have consistently shown associations between early-life chronic stressors and vulvodynia onset.

Aim: We examined rumination as a specific stress response involved in the psychobiological mechanism of vulvodynia.

Is chronic stress during childhood associated with adult-onset vulvodynia?

Background: Vulvodynia is an unexplained chronic vulvar pain condition. Case-control studies provide opportunities to examine potential mechanisms by which vulvodynia may develop. Findings inform etiological models that can be tested in subsequent prospective studies.

The influence of depression and anxiety on risk of adult onset vulvodynia.

Background: Studies have shown that women with vulvodynia are more psychologically distressed than women without vulvodynia. These studies, however, have not effectively established temporal associations between diagnosed psychiatric disorders and vulvodynia.

Methods: The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) was administered to 240 case-control pairs of women with and without vulvodynia.

The cognitive mediation of obsessive-compulsive symptoms: a longitudinal study.

Contemporary cognitive models of obsessive-compulsive disorder (OCD) posit that OC symptoms arise from negative interpretations of intrusive thoughts, which are derived from trait-like dysfunctional assumptions ("obsessive beliefs;" e.g., concerning overestimates of responsibility).
