We use fits to recent published CPLEAR data on neutral kaon decays $π^+π^-$ and $πeν$ constrain the CPT--violation parameters appearing in a formulation of system as an open quantum-mechanical system. The obtained upper limits are approaching range suggested by certain ideas concerning quantum gravity.

This article examines the effects of globalization on well-being migrant professional athletes. Interviews with 20 touring golfers reveal that players experience many personal problems—such as loneliness, isolation, low decision latitude, social support, and effort-reward imbalance—which have been identified “strong predictors mental ill-health” (Leka & Jain, 2010, p. 65). Feelings loneliness isolation developed were regularly apart from family friends, spent most their time other whom...

Abstract The external demands of small-sided games (SSGs) according to the positional role are currently unknown. Using a Catapult Minimax X3 5 Hz GPS, with 100 tri-axial accelerometer, we compared accumulated player workload per min (PLacc·min -1 ) during friendly youth match play (MP) (11 vs. 11) and SSGs (2 2, 3 3, 4 4). Significant differences existed between all MP for PLacc·min (F = 21.91, p < 0.001, η2 0.38), individual X 27.40, 0.43), Y 14.50, 0.29) Z 19.28, 0.35) axis loads....

An enhancement in the ${\ensuremath{\Lambda}}^{0}p$ mass spectrum from reaction ${K}^{\ensuremath{-}}d\ensuremath{\rightarrow}{\ensuremath{\Lambda}}^{0}p{\ensuremath{\pi}}^{\ensuremath{-}}$ at ${K}^{\ensuremath{-}}$ momenta of 1.45 and 1.65 $\frac{\mathrm{GeV}}{c}$ is reported. The peak distribution occurs $\ensuremath{\simeq}2129$ MeV width half-height $\ensuremath{\simeq}10$ MeV. A possible interpretation this effect given.
