The purpose of the study was to examine the effects of running speed and surface compliance on shock attenuation (SA) characteristics for male and female runners. We were also interested in identifying possible kinematic explanations, specifically, kinematics of the lower extremity at foot-ground contact, for anticipated gender differences in SA. Fourteen volunteer recreational runners (7 male,...

As musculoskeletal modeling improves, the possibilities of calculating more diverse parameters or performing specific motion analyses increase. However, customization might require a different approach that is not offered by original software it requires complex knowledge. Patient lift was analyzed in Plug-in-Gait (PiG) marker-set-based kinematic model Rhino Grasshopper for range calculation ar...

contrary to the long period ground motions that can be predicted and estimated, high frequency ground motions have random character and behave stochastically. stochastic modeling methods are usually used for the modeling of high frequency ground motions where there are not strong ground motion records. stochastic methods are of two kinds: in the first one, the seismic source is considered as a ...

For diastolic function (DF) quantification, transmitral flow velocity has been characterized in terms of the geometric features of a triangle (heights, widths, areas, durations) approximating the E-wave contour, whereas mitral annular velocity has only been characterized by E'-wave peak amplitude. The fact that E-waves convey global DF information, whereas annular E'-waves provide longitudinal ...

The Radcliffe Wave (RW) is a recently discovered sinusoidal vertical feature of dense gas in the proximity Sun. In disk plane, it aligned with Local Arm. However, origin its undulation still unknown. This study constrains kinematics RW, using young stars and open clusters as tracers, explores possibility this oscillation being part more extended mode. We median velocity trends along RW extend f...
