In this study, we analyzed the relationship between ground reaction force (GRF) and both leg kinetics in kicking pullovers, with aim of clarifying mechanics techniques for acquiring vertical GRF moment single-leg takeoffs aerial rotation. applied to support foot kinematics were recorded takeoff phase successful pullovers by 11 adult males. Using a 12-segment, sagittal-plane rigid body link mode...

We analyze a simple model for running: a three-dimensional springloaded inverted pendulum carrying a point mass (3D-SLIP). Our formulation reduces to the sagittal plane SLIP and horizontal plane lateral leg spring (LLS) models in the appropriate limits. Using the intrinsic geometry and symmetries and appealing to the case of stiff springs, in which gravity may be neglected during stance, we der...

Real-time PCR was evaluated as a quantitative diagnostic method for Chlamydia pneumoniae infection using different respiratory samples. Real-time PCR had efficiency equal to or better than that of nested touchdown PCR. This study confirmed sputum as the best sampling material to detect an ongoing C. pneumoniae infection.

This work provides a feasible solution to the shipborne short landing problem for thrust-vectoring V/STOL vehicles. The takeoff and rolling vertical strategy was designed in this work. First, design reference established by flying performance mission requirements, including performance, deceleration trajectory stability, velocity conversion corridor, using attainable equilibrium set methods bas...

Small terrestrial animals continually encounter sloped substrates when moving about their habitat; therefore, it is important to understand the mechanics and kinematics of locomotion on non-horizontal substrates as well as on level terrain. To this end, we trained gray short-tailed opossums (Monodelphis domestica) to move along level, 30 degrees inclined, and 30 degrees declined trackways instr...
