We study real-time electron dynamics in a molecular junction with a variety of approximations to the electronic structure, toward the ultimate aim of determining what ingredients are crucial for the accurate prediction of charge transport. We begin with real-time, all electron simulations using some common density functionals that differ in how they treat long-range Hartree-Fock exchange. We fi...

BACKGROUND Exaggerated cardiovascular reactions to psychological stress are considered a risk factor for cardiovascular morbidity. Social support may reduce such risk by attenuating cardiovascular reactivity to stress. PURPOSE To examine the effects of three independent social support variables and their interaction on cardiovascular reactivity to acute stress. The variables were stranger or ...

Based on the revised social contact theory, correlates of cross-ethnic friend nomination among 580 African American, 948 Asian-descent, 860 Latino, and 3986 White adolescents were examined. Socioeconomic and academic disparities between ethnic groups differentiated cross-ethnic friend nomination between schools for all groups but African Americans. For all groups, cross-ethnic friend nomination...

A specific antigenic component in mouse leukemias induced by Friend virus has been demonstrated by cytotoxic tests in vitro. Serum from mice of several inbred strains immunized with histoincompatible Friend leukemia tissue contained antibody that was cytotoxic in vitro for leukemia cells induced by Friend virus in the strains providing the immune serum. Unexpectedly, a high proportion of mice f...

Argumentation, whether philosophical or formal and mathematical, is a discipline of interdisciplinary nature, per se. The recent works on the computational argumentation formalism and their foundations, however, have rested only on logic or logical account. In this paper, we reconsider Dung’s seminal argument acceptability notion in the context of Heider’s socio-psychological balance theory, wh...
