We discuss the influence of anomalous tt̄G couplings on total and differential tt̄ production cross sections in hadron–hadron collisions. We study in detail the effects of a chromoelectric and a chromomagnetic dipole moment, d′t and μ ′ t, of the top quark. In the d′t–μ ′ t plane, we find a whole region where the anomalous couplings give a zero net contribution to the total top production rate. I...

Radiatively driven transfer flow perpendicular to a luminous disk was examined under a fully special relativistic treatment, taking into account radiation transfer. The flow was assumed to be vertical, and the gravity, the gas pressure, and the viscous heating were ignored. In order to construct the boundary condition at the flow top, the magic speed above the flat source was re-examined, and i...

Magnetic cores of passive components are required to have low hysteresis loss, which is dependent on the coercive force. Since it is well known that the coercive force becomes zero at the superparamagnetic regime below a certain critical size, we attempted to synthesize Ni nanoparticles in a size-controlled fashion and investigated the effect of particle size on the magnetic properties. Ni nano...

A direct numerical simulation (DNS) of an unstably stratified convective boundary layer with system rotation was performed to study top-down and bottom-up diffusion processes. In order to better understand near-wall dynamics associated with scalar diffusion in the absence of surface roughness, direct simulation is utilized to numerically integrate the governing equations that model the atmosphe...

Chlorinated paraffins (CPs) were analyzed in marine wildlife from Greenland, Iceland, and the Swedish west coast. CPs up to C29 detected samples Arctic, indicating long-range transport of an industrial chemical group with a 2-million-ton annual production volume. CP concentrations generally higher biota The Sweden/Arctic concentration ratios for very-short-chain (vSCCPs, C<10), short-chain (SCC...
