We study the propagation coherence for neutrino oscillations in media with different density profiles. For each profile, we find dependence of length, $L_{coh}$, on energy and address issue correspondence results distance energy-momentum representations. The key new feature matter is existence ranges enhanced around energies $E_0$ "infinite coherence" at which $L_{coh} \rightarrow \infty$. In c...

results all variables reached a peak at 1 minute post-jump. salivary alpha-amylase, galvanic skin responses and heart rate did not return to basal value at 90 minutes post-jump, while cortisol returned to basal value at 90 minutes post-jump. conclusions this evidence indicates that parachute jumping is accompanied by a dissociation of sns and hpa response patterns in novice parachutists, showin...

To gain a better understanding of push-off mechanics in speed skating, forward simulations were performed with a model comprising four body segments and six muscles. We started with a simulated maximum height one-legged jump, obtained by optimization of muscle stimulation time histories. The simulated jump was very similar to one-legged jumps produced by a human, indicating that the model was r...

Relations between force-velocity characteristics of the multijoint movement of the lower limbs and vertical jump performance were investigated. A total of 67 untrained subjects (age: 19.54 +/- 2.38 years; height: 166.88 +/- 8.53 cm; body mass: 59.14 +/- 10.82 kg, mean +/- SD) performed isometric and isotonic knee-hip extension movements on a servo-controlled dynamometer, and the force-velocity ...

Jumping is an important locomotor behaviour used by many animals. The power required to perform a jump is supplied by skeletal muscle. The mechanical properties of skeletal muscle, including the power it can produce, are determined by its composition, which in turn reflects trade-offs between the differing tasks performed by the muscle. Recent studies suggest that muscles used for jumping are r...

We study the mean first-passage time (MFPT) for asymmetric continuous-time random walks in continuous-space characterised by waiting-times with finite and jump-sizes both variance. In asymptotic limit, this well-controlled process is governed an advection-diffusion equation MFPT results to be when advecting velocity direction of boundary. derive a nonhomogeneous Wiener-Hopf integral that allows...

the discharge data used for hydrological modeling should be the long-term suitable random data without trend and jump which is followed a specific statistical distribution. in this study, the above mentioned conditions were evaluated for 31 years period (1974-2004) of annual mean discharge data of 10 gauging stations of west azarbaijan province. for this purpose, the non-parametric spearman cor...

the purpose of this study was to investigate the effects of body mass index on fundamental motor skills performance in 7-8-year-old boys in hamedan. forthis purpose, 72 elementary students were selected via cluster randomization from the elementary schools of hamedan and divided into three groups: fat, normal, and thin according to percentile diagram. then, tgmd-2 was performed by children and ...

In very recent experimental work, diffusive motion of individual particles in a dense columnar phase of colloidal suspension of filamentous virus particles probed by means of fluorescence video microscopy [S. Naderi, E. Pouget, P. Ballesta, P. van der Schoot, M. P. Lettinga, and E. Grelet, Phys. Rev. Lett. 111, 037801 (2013)]. Rare events were observed in which the minority fluorescently labele...

purpose the purpose of this study was to describe the body structure and morphological characteristics of tunisian elite handball players, and to determine the effect of these variables on functional and physical performance levels. methods a sample of 42 male handball players (mean age 21.98±3.24 years; training duration 12 years) at international level was submitted to a test battery comprisi...
