The purpose of this study was to investigate the mechanism of foot strike pattern (FSP) adaptations to a minimalist shoe among the different heel height in running. We found that the strike index (SI) and foot strike angle (FSA) were systematically affected by changes in heel height. We also observed a linear correlation between FSA and SI. However, no changes in initial foot angle (IFA) were f...

Integral Transport methods were used to calculate the x-ray intensity in a NOVA hohlraum. Two cases were examined: the nominal case in which all five lasers strike either side of the hohlraum and the abnormal case for which five lasers strike the right side but only four strike the left. As expected, the uniform case produces a fairly uniform illumination over the capsule, whereas the abnormal ...

There are two types of Asian options in the financial markets which differ according to the role of the average price. We give a symmetry result between the floating and fixed-strike Asian options. The proof involves a change of numéraire and time reversal of Brownian motion. Symmetries are very useful in option valuation and in this case, the result allows the use of more established fixed-str...

The predatory labial strike of dragonfly (Aeschna) larvae could be elicited by an artificial water jet stimulus. The larvae showed fair prey-catching ability even when visually deprived, whereas when deprived of mechanosensory and visual information, the ability decreased sharply. Also, immobilized prey were unable to elicit a strike even from intact larvae. The percentage of labial strike (PLS...

Research concerning forefoot strike pattern (FFS) versus rearfoot strike pattern (RFS) running has focused on the ground reaction force even though internal joint contact forces are a more direct measure of the loads responsible for injury. The main purpose of this study was to determine the internal loading of the joints for each strike pattern. A secondary purpose was to determine if converte...

BACKGROUND Impulsive forces in the knee joint have been suspected to be a co-factor in the development and progression of knee osteoarthritis. We thus evaluated the impulsive sagittal ground reaction forces (iGRF), shock waves and lower extremity joint kinematics at heel strike during walking in knee osteoarthritis (OA) patients and compared them to those in healthy subjects. SUBJECTS AND MET...
