A common source of error when detecting heel-strike moments utilizing split force-plate treadmills is unwillingly stepping on contra-lateral force-plate. In this study, we quantified this error when heel-strike was detected based on such erroneous data and compared three methods to investigate how well the heel-strikes and stride-intervals were detected with erroneous data. Eleven subjects walk...

Although the Andes are believed to have resulted mainly from crustal shortening, the shortening history remains debated and appears to require lateral (along-strike) crustal flow. Three-dimensional viscous flow modeling shows that, within geological uncertainties, the Andes may have been produced by either Neogene shortening alone or with significant preNeogene shortening. These scenarios requi...

Noncontact anterior cruciate ligament (ACL) injuries often occur during lateral cutting maneuvers, in which extension, adduction, and external rotation create high loads on the ACL. The aim of this study was to examine knee moments and foot strike patterns during lateral cutting when shod (SD) and barefoot (BF). Fifteen NCAA Division III athletes (7 female and 8 male; age 20.2 ± 1.5 years; mass...

[1] The tectonic evolution of Mars has been driven primarily by the interaction of Tharsisinduced loading stresses with a uniform contractional stress field, leading to global assemblages of graben and wrinkle ridges. Until recently, strike-slip faults have appeared to be largely absent from the tectonic record. We here present evidence for a new set of Noachian to Early Hesperian strike-slip f...

The change of motion mode multistage active strike-slip faults controls the segmentary types faults, which is seldom studied.Based on high-precision 3D seismic data and principle structural analysis, this paper defines evolution characteristics tp12cx fault in key period identifies segmentation types. Combined with statistical results drilling production width, it demonstrated that different se...

The opposite-sense fault block rotation across the continental strike-slip faulting plays an important role in accommodating crustal deformation north of East Iran orogen. This research constrains post-Neogene kinematics NW-SE to E-W left-lateral transpressional zones at northern termination N-S striking right-lateral Neh system Using two case studies, we analyzed Birjand splay and Shekarab tra...

Western Aphrodite Terra, Venus, is characterized by a series of parallel linear structural discontinuities 2000-4000 km in length and 100-200 km wide, which strike at high angles to the general topographic trend of the Aphrodite Terra highlands. The broad characteristics of the cross-strike discontinuities (CSDs) are similar to both strike-slip fault zones and terrestrial oceanic fracture zones...

+Scanlan, S F; Favre, J; Andriacchi, T P + Stanford University, Stanford, CA, 2 VA Palo Alto Health Care System, Palo Alto, CA [email protected] INTRODUCTION: It has been suggested that the spatial variations in the morphology and mechanical properties of articular cartilage are conditioned to the cyclic loading during ambulation [1]. Specifically it has been shown that regional variation i...

Rodents display characteristic defense responses to predators that are influenced by predatory imminence. The midbrain periaqueductal gray (PAG) serves an important role controlling these responses. The most influential model states that variations in defensive topography are due to distinct PAG regions: ventrolateral PAG (VLPAG) controls postencounter defense, such as freezing and immobility, ...
