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...

Minimalist running footwear has grown increasingly popular. Prior studies that have compared lower extremity biomechanics in minimalist running to traditional running conditions are largely limited to a single running velocity. This study compares the effects of running at various speeds on foot strike pattern, stride length, knee angles and ankle angles in traditional, barefoot, and minimalist...

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...

Veterinary surgeons are sometimes asked to examine animals that have been found dead without premonitory signs. When death occurs in this manner and without explanation, the term ‘sudden unexpected (unexplained) death’ (SUD) is used.This does not necessarily imply that death was instantaneous, but is usually defined as the death of an animal that appears healthy but dies suddenly within a few m...

Heel strike detection is an important cue for human gait recognition and detection in visual surveillance since the heel strike position can be used to derive the gait periodicity, stride and step length. We propose a novel method for heel strike detection using a gait trajectory model, which is robust to occlusion, camera view and to low resolution which can generalize to a variety of surveill...

The decomposition procedure suggested for magnetotelluric (MT) data in a companion paper is illustrated by examples. Adjacent pairs of stations are examined to test for common features in their MT response. The method analyzes the real and quadrature parts of an impedance tensor separately, and the results for the real and quadrature parts are compared, and in some cases combined, at the end. V...

We consider the problem of pricing European forward starting options in the presence of stochastic volatility. By performing a change of measure using the asset price at the time of strike determination as a numeraire, we derive a closed-form solution based on Heston’s model of stochastic volatility.

We would like to thank the authors of the commentary [1] for pointing out the error in the analysis of the early winter months (Oct–Dec) in our article. We find that this is indeed correct, and wish to apologize for such an error in our analysis. After correcting the error we have been able to reproduce Figure 1 from the commentary. We wish to point out that we have checked that this issue has ...

Strike activity in Spain is unusually high compared to most other developed countries and, moreover, it has remained at a high level for the last decade, whilst strike rates have been falling in most other countries. One possible explanation for this poor strikes record is Spanish labour law with respect to industrial disputes which may be too permissive, or have remained permissive whilst othe...
