Joint European Torus discharges which demonstrate the critical role the safety factor profile, q, can play in the formation of internal transport barriers (ITB) are examined. In these discharges, the target parameters, including the E x B flows, were kept virtually the same, except for the q profile. In a discharge with a nonmonotonic q, an ITB was triggered whereas a discharge with monotone q ...

background: prevention of slipping accidents requires provision of adequate friction through the use of suitable combinations of footwear and underfoot surfaces. shoe sole tread groove is one of the important factors on friction coefficient during walking. objective: to measure the effect of different shoe sole tread groove depths and different surfaces on the required quotient of friction (q),...

Pion transition form factor for the process γγ → π at space-like values of photon momenta is calculated within the effective quark-meson model with the interaction induced by instanton exchange. The leading and next-to-leading order power asymptotics of the form factor and the relation between the light-cone pion distribution amplitudes of twists 2 and 4 and the dynamically generated quark mass...

The domestication gene Q is largely responsible for the widespread cultivation of wheat because it confers multiple traits. However, underlying molecular mechanisms how regulates these traits remain unclear. In this study, we identify a Q-interacting protein TaLAX1, basic helix–loop–helix transcription factor, through yeast two-hybrid assays. Using biochemical and genetic approaches, explore ro...
