The anterior cruciate ligament (ACL) injury is a common occurrence in sports requiring stop-jump tasks. Single- and double-leg stop-jump techniques are frequently executed in sports. The higher risk of ACL injury in single-leg drop landing task compared to a double-leg drop landing task has been identified. However the injury bias between single- and double-leg landing techniques has not been i...

Asset returns have been modeled in continuous time as diffusions by Black and Scholes (1973) and Merton (1973), as pure jump processes by Cox and Ross (1976), and as jump-diffusions by Merton (1976). The jump processes studied by Cox and Ross display finite activity, while some recent research has considered some pure jump processes with infinite activity. Two examples of these infinite-activit...

In this article, we aim to study the stability and dynamic transition of an electrically conducting fluid in presence external uniform horizontal magnetic field rotation based on a Boussinesq approximation model. By analyzing spectrum linear part model verifying validity principle exchange stability, take hybrid approach combining theoretical analysis with numerical computation from simple real...

let g be a (p,q) graph. an injective map f : e(g) → {±1,±2,...,±q} is said to be an edge pair sum labeling if the induced vertex function f*: v (g) → z - {0} defined by f*(v) = σp∈ev f (e) is one-one where ev denotes the set of edges in g that are incident with a vertex v and f*(v (g)) is either of the form {±k1,±k2,...,±kp/2} or {±k1,±k2,...,±k(p-1)/2} u {±k(p+1)/2} according a...

purpose the aim of this study was to investigate the effect of a combined program including sprint repetitions and drop jump training in the same session on male handball players. methods twenty-two male handball players aged more than 20 years were assigned into 2 groups: experimental group (n=11) and control group (n=11). selection was based on variables “axis” and “lines”, goalkeepers were n...

We propose a new transaction-level bivariate log-price model, which yields fractional or standard cointegration. To the best of our knowledge, all existing models for cointegration require the choice of a fixed sampling interval ∆t. By contrast, our proposed model is constructed at the transaction level, thus determining the properties of returns at all sampling frequencies. The two ingredients...

The conformational transitions of five viroid species were studied by melting analysis and by fast and slow temperature jump techniques. Experiments with the fast temperature jump technique had to be carried out in 10 mM Na-cacodylate, 0.1 M NaCl, 4 M urea, 1 mM EDTA, pH 6.8. In addition to the highly cooperative main transition (Tm between 46.5 and 49 degrees C for different viroid species [1]...

the control of hydraulic jump through thin-crested sills in a trapezoidal channel was studied theoretically as well as experimentally. the experiments were conducted in a specially designed stilling basin for 1:1 side slope. the results show that for a given side slope, end sill increases the stability of the jump within the stilling basin. it also causes a 13-15 percent reduction in the length...

Thirty-nine thunderstorms are examined using multiple-Doppler, polarimetric and total lightning observations to understand the role of mixed phase kinematics and microphysics in the development of lightning jumps. This sample size is larger than those of previous studies on this topic. The principal result of this study is that lightning jumps are a result of mixed phase updraft intensification...
