Using the embedded atom method (EAM), we computed lateral interactions between H atoms on Ni(ll1) and on Pd(100). For H/Ni(lll) the binding-energy difference between the two 3-fold sites is very small. As expected due to the very small separation, at nearest neighbor sites there is an extreme repulsion. The only other non-negligible interactions are repulsions of comparable size (a few mev) bet...

a new method is developed for a fast identification of the stability situation of industrial processes. the proposed method includes two factor ratios of the control constants for the upper and lower control limits to process these constants. an indication ratio is then defined as the ratio of the maximum data range value to the difference between the maximum and average values for individual d...

We study the associated jet multiplicity arising from t–channel BFKL gluon evolution in forward dijet production at hadron colliders. Previous results have shown that the effect of conserving overall energy and momentum is to introduce a pdf suppression that completely compensates the predicted exponential BFKL rise with rapidity difference between the leading dijets. However, we show that ther...

The CP violating Dashen phase in QCD is predicted by chiral perturbation theory to occur when the up-down quark mass difference becomes sufficiently large at fixed down-quark mass. Before reaching this phase, all physical hadronic masses and scattering amplitudes are expected to behave smoothly with the up-quark mass, even as this mass passes through zero. In Euclidean space, the topological su...

The nuclear modification factor RAA of nonphotonic electrons in Au + Au collisions at √sNN = 200 GeV is studied by considering the decays of heavy-flavor hadrons produced in a quark coalescence model. Although an enhanced c/D ratio is predicted by the coalescence model, it is peaked at small transverse momenta (∼2 GeV) due to the large difference between heavy and light quark masses. As a resul...

This article provides a meta-analytic review of the relationship between the quality of leader-member exchanges (LMX) and citizenship behaviors performed by employees. Results based on 50 independent samples (N = 9,324) indicate a moderately strong, positive relationship between LMX and citizenship behaviors (rho = .37). The results also support the moderating role of the target of the citizens...

This study evaluated two measures that have been used to compare the performance of particular subjects to outcomes predicted by the articulation index (Al). One measure was the proficiency factor, that is, the ratio between the Al derived from a test score and the Al derived from objective measurements of speech and noise spectra. The other measure was the difference between rationalized arcsi...

On the basis of both Geschwind andBehan's (1984) theory—that at least part of the genesis of left-handedness can be ascribed to overexposure to testosterone during fetal development—andDorner's (1980;Dorneretal., 1991) theory—that transsexuality emerges from prenatal overor underexposure to androgens infemale-to-male (FTM) andmale-to-female (MTF) transsexuals, respectively—it was predicted that...

The optimization method based on the surrogate model has been widely used in simulation and calculation process of complex engineering models. However, this process, low accuracy computational efficiency always an urgent problem that needs to be solved. Aimed at problem, combined with two characteristics global search local detection, a filling criterion multiple points is firstly proposed name...
