Warren, Young, and Lee (1986) found that treadmill runners control step length by regulating vertical impulse, which could be modulated by the optical time-to-contact variable tau. In contrast, Patla, Robinson, Samways, and Armstrong (1989) report a 40% contribution of horizontal impulse in overground running and a control strategy that depends on the timing of target cuing, undermining the tau...

A Lagrangian numerical method based on impulse variables is analyzed. The relation between impulse vectors and vortex dipoles with a prescribed dipole moment is presented and used to adapt the high-accuracy cutoo functions of vortex methods for use in impulse-based methods. The long-time implementation of the impulse method is shown to contain a source of error whose growth in time renders impu...

Research has found an upward trend in impulse buying in general, and impulse buying is frequently foreseen among mall shoppers. Impulse purchases account for over $4 billion in annual sales in the U.S. (Mogelonsky, 1998). Retailers have found that over 50 percent of mall shoppers purchase on impulse (Nichols et al., 2001). More than one third of all department store purchases were bought on imp...

cardiac conduction system enables the heart to pulsate continuously by producing electric impulse and conducting it. as the anatomical information about cardiac conduction system in human being and other mammals needed in various fields of sciences, such as anatomy, histology, physiology, pathology and cardiology, the present review article intends to provide this basic information about an imp...

No consensus has been reached on how musculoskeletal system injuries or aging can be explained by a walking plantar impulse. We standardize the plantar impulse by defining a principal axis of plantar impulse. Based upon this standardized plantar impulse, two indexes are presented: plantar pressure record time series and plantar-impulse distribution along the principal axis of plantar impulse. T...
