this study aimed at investigating the effect of bcaas consumption on wrestlers' creatine kinase (ck) activity in a three-month depth jump exercise. for this purpose, 22 male wrestlers from zanjan province (age 21.54±3.52 yr, weight 66.18±3.76 kg, height 168.36±2.41 cm, bmi 23.34±1.97 kg/m2) were randomly selected and divided into two groups. during the mentioned period, both groups had the...

Uncertain differential equation with jumps, as a crucial tool to deal with a discontinuous uncertain system, is a type of differential equation driven by both canonical Liu process and uncertain renewal process. So far, a concept of stability in measure for an uncertain differential equation with jumps has been proposed. As a supplement, this paper proposes a concept of almost sure stability fo...

In this paper, we consider a perturbed compound Poisson risk model with two-sided jumps. The downward jumps represent the claims following an arbitrary distribution, while the upward jumps are also allowed to represent the random gains. Assuming that the density function of the upward jumps has a rational Laplace transform, the Laplace transforms and defective renewal equations for the discount...

We aim to determine the influence of sports floorings and sports shoes on impact mechanics and performance during standardised jump tasks. Twenty-one male volunteers performed ankle jumps (four consecutive maximal bounds with very dynamic ankle movements) and multi-jumps (two consecutive maximal counter-movement jumps) on force plates using minimalist and cushioned shoes under 5 sports flooring...

Stock returns are characterized by extreme observations, jumps that would not occur under the smooth variation typical of a Gaussian process. We find that jumps are prevalent in most countries. This has been noticed before in some countries, but there has been little investigation of whether the jumps are internationally correlated. Their possible inter-correlation is important for investors be...

Recently, many people have found polarisation features in the SCIAMACHY Level-1c spectrum, in the form of jumps. The jumps are found to be caused by the polarisation correction algorithm, which is evidenced by the fact that the jumps occur only when the polarisation correction is switched on, and only at cluster transitions where the integration time changes. We explain the origin of the jumps,...

Many studies on maximal vertical jumps have been done in order to clarify the way human exerts ballistic movements (Bobbert and Ingen Schenau, 1988). However, humans often perform jumps with various take-off angles in various situations and the different muscular and segmental coordination may be involved in the jumps with the different take-off angles. For these reasons, it is necessary to inv...

We suggest a one dimensional jump detection algorithm based on local polynomial tting for jumps in regression functions (zero-order jumps) or jumps in derivatives ((rst-order or higher-order jumps). If jumps exist in the m-th order derivative of the underlying regression function, then an (m + 1) order polynomial is tted in a neighborhood of each design point. We then characterize the jump info...

2014 The results of calculations of higher flux jumps positions in hard superconductors in decreasing magnetic field have been presented. It has been shown that flux jumps and corresponding stability limits are dependent on maximal magnetic field value in the cycle, which influences mainly first stability limit in decreasing field. Positions of other flux jumps have been determined for two simp...

We develop Bayesian Markov chain Monte Carlo methods for inferences of continuoustime models with stochastic volatility and infinite-activity Levy jumps using discretely sampled data. Simulation studies show that (i) our methods provide accurate joint identification of diffusion, stochastic volatility, and Levy jumps, and (ii) affine jumpdiffusion models fail to adequately approximate the behav...
