Molecular dynamics simulations using tight-binding many body potential are carried out to study the roller imprint process of a gold single crystal. The effect of the roller tooth's taper angle, imprint depth, imprint temperature, and imprint direction on the imprint force, adhesion, stress distribution, and strain are investigated. A two-stage roller imprint process was obtained from an imprin...

Homogeneous anisotropict urbulence simulations are used to determine off-diagonal componentso fthe Reynolds stress tensora nd itsp arameterizationi nt erms of turbulentv iscosity and Λ-effect.T he turbulence is forced in an anisotropic fashion by enhancing thestrengthofthe forcing in thevertical direction. TheCoriolis force is included with arotationaxis inclined relativetothe vertical directio...

[1] In this paper we consider the problem of modeling a turbulent pulsating boundary layer over ripples. We compare the results of two modeling strategies, Wilcox’s k w Reynolds-Averaged Navier-Stokes equations (RANS) and large-eddy simulation (LES) employing the Lagrangian dynamic eddy viscosity model. The geometry and parameters employed are relevant to nearshore oceanic flows, and the result...

Results of this experiment demonstrate that individualists and collectivists react differently to minority influence. Based on the distinction between objectivity and preference norms in the minority influence literature, we hypothesize that individualism and collectivism influence (A) responses to minority influence (focusing on the target of influence) and (B) effectiveness of minority influe...

To identify preoperative factors which influence the effectiveness of strabismus surgery in adults, we retrospectively reviewed the records of 179 patients > 15 years old (131 with exotropia, 48 with esotropia) who had had combined recession and resection surgery for correction of horizontal strabismus. Eighteen preoperative variables were evaluated; those with significant influence on the surg...

A prospective study was undertaken on 50 acute, consecutive fractures of the radial head. Clinical examination and stress testing were performed on each patient. A valgus stress radiograph, in conjunction with clinical stress testing, was used to assess competence of the medial elbow ligaments. Axial stability of the radius was determined by the axial stress test. Eleven patients (22%) sustaine...

• We used VR to examine the buffering effects of vertical greenery against stressors. Self-report measures show prevented reduction in positive affect. Heart rate variability suggests increase stress. Our results indicate that can be buffer
