The critical value of the reaction rate able to sustain the propagation of an invasive front is obtained for general non-Markovian biased random walks with reactions. From the Hamilton-Jacobi equation corresponding to the mean field equation we find that the critical reaction rate depends only on the mean waiting time and on the statistical properties of the jump length probability distribution...

[Purpose] This study aimed to investigate the effect of pelvic adjustment on vertical jump height (VJH) in female university students with functional leg length inequality (FLLI). [Subjects] Thirty female university students with FLLI were divided into a pelvic adjustment group (n = 15) and a stretching (control) group (n = 15). [Methods] VJH was measured using an OptoGait. [Results] After the ...

BACKGROUND Pitching biomechanical analysis has been recommended as an important component of performance, injury prevention, and rehabilitation. Normal values for youth pitching stride length have not been established, leading to application of normative values found among professional pitchers to youth pitchers. HYPOTHESES The average youth pitching stride length will be significantly less t...

Int J Exerc Sci 1(1) : 22-29, 2008. The purpose of this study was to determine if upper body segment length or mass contributes to vertical jump (VJ) displacement. Seventeen men (n=9) and women (n=8) who were active recreationally participated in this investigation. Subjects performed VJ for maximal displacement, and skeletal length measurements of the humerus (acromion following the lateral li...

Abstract – The Dynamic Field Theory (DFT) has been used to account for spatial recall biases in children and adults. This paper extends the DFT to a second spatial working memory task, position discrimination. The DFT captures details of adults’ discrimination performance, as well as predicting developm...

Macaque monkeys were trained to recognize the repetition of one of the images already seen in a sequence of random length. On average, performance decreased with sequence length. However, this was due to a complex combination of factors, as follows: performance was found to decrease with the separation in the sequence of the test (repetition image) from the cue (its first appearance in the sequ...

background: asthma is a common condition in general medical practice, and it accounts for about 1% of all ambulatory hospital visits. nowadays, hospitalization rates for asthma have actually been increased in some demographic subgroups despite recent advances in treatment. understanding the underlying factors that contribute to hospitalization and especially duration of the hospitalization of a...
