The observation and investigation of nonlinear effects in catalytic reactions provides valuable mechanistic insight. However, the applicability of this method was, until now, limited to molecules possessing chirality and therefore to asymmetric synthesis. The concept of nonlinear effects is expanded to catalytic reactions beyond asymmetric catalysis by using derivatives instead of enantiomers a...

T his article examines cross-price promotional effects in a dynamic context. Among other things, we investigate whether previously established findings hold when consumer and competitive dynamics are taken into account. Five main influential effects (asymmetric price effect, neighborhood price effect, asymmetric share effect, neighborhood share effect, and private label versus national brand as...

This study applies the information system success model to analyze the website quality of a restaurant (the website of T.G.I. Friday’s as the research case). Website quality was analyzed according to three dimensions: information quality, system quality, and service quality. Customer perceptions related to losses and gains due to website quality were assessed to determine whether such perceptio...

The univariate Generalised Autoregressive Conditional Heterscedasticity (GARCH) model has successfully captured the symmetric conditional volatility in a wide range of time series financial returns. Although multivariate effects across assets can be captured through modelling the conditional correlations, the univariate GARCH model has two important restrictions in that it: (1) does not accommo...

conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...

conclusions the lack of difference between adma levels in patients with pa and eh suggests that endothelial dysfunction is more likely related to hypertension per se than to the specific etiology of elevated blood pressure. results patients with pa had significantly higher concentrations of adma than healthy controls (0.488 ± 0.085 vs. 0.433 ± 0.053 μmol/l, p = 0.027). no difference was found i...

Simultaneous effects of slip and heat transfer on peristaltic transport of an incompressible electrically conducting viscous fluid  in an  asymmetric channel is studied under the assumptions of long wavelength and low Reynold number .The  asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitudes and phase.Exect solutions for stream function,velocity ...

Peristaltic transport of an incompressible electrically conducting viscous fluid in an inclined planar asymmetric channel is studied. The asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase. The closed form solutions of momentum and energy equation in presence of viscous dissipation term are obtained for long wave length and low Reynol...
