Kickboxing is a full contact combat sport in which punches, kicks, elbow and knee strikes are allowed. A typical kickboxing tournament has up to eight fights (bouts) on the same day; therefore the ability of an athlete to recover quickly between bouts is very important. Acupuncture might be a safe and substance free way to support kickboxers’ performance, as acupuncture on S34 has been shown to...

Recent observations of white dwarfs in globular clusters indicate that these stars may get a velocity kick during their time as giants. This velocity kick could originate naturally if the mass loss while on the asymptotic giant branch is slightly asymmetric. The kicks may be large enough to dramatically change the radial distribution of young white dwarfs, giving them larger energies than other...

A THz "half-cycle" pulse is a fast ( <1 ps) unipolar pulse, followed by a slow unipolar pulse of opposite polarity. We found that the interaction of such THz pulses with very high Rydberg states results in a displacement of the electron within the atom, while the ionization is strongly suppressed. In classical terms: the first fast unipolar feature corresponds to a start kick of the Rydberg ele...

We report an experimental and theoretical study of the dynamics of cold atoms subjected to closely-spaced pairs of pulses in an optical lattice. The experiments show the interplay between fully coherent quantum dynamics and a novel momentum-diffusion regime: for all previously-studied δkicked systems, chaotic classical dynamics shows diffusion with short-time (2 or 3-kick) correlations; here, c...

We study the dynamics of a quantum rotator, impulsively kicked according to the almost-periodic Fibonacci sequence. A special numerical technique allows us to carry on this investigation for as many as 10(12) kicks. It is shown that above a critical kick strength, the excitation of the system is well described by regular diffusion, while below this border it becomes anomalous and subdiffusive. ...

In this paper we propose a new model for impurity diffusion in compound semiconductors. The model incorporates both the kick-out and the dissociative mechanism, as well as charge effects; the resulting system includes as limit cases many models that have previously appeared in the literature. An initial–boundary value problem that models surface source in-diffusion conditions is then considered...
