Background: Investigations of running gait among barefoot and populations have revealed a diversity of foot strike behaviors, with some preferentially employing a rearfoot strike (RFS) as the foot touches down while others employ a midfoot strike (MFS) or forefoot strike (FFS). Here, we report foot strike behavior and joint angles among traditional Hadza hunter-gatherers living in Northern Tanz...

We consider the problem of finding bounds on the value of fixed-strike and floatingstrike Asian options. A good lower bound for both types was derived in Rogers & Shi (1995). We provide an alternative derivation, which leads to a simpler expression for the bound, and also to the bound given by Curran (1992) for fixed-strike options; we derive an analogous bound for floating-strike options. Comb...

Recent studies comparing terrestrial versus aquatic locomotion in animals have shown that changes in kinematics, muscular activation patterns, and performance across media are often dramatic. Surprisingly, however, despite the importance of feeding to the survival of most animals, few studies have compared differences in feeding behaviour between media. The present study compares prey-capture b...

There is an increasing need for secure and fast encryption algorithms to support applications communication protocols, business models. In this paper, we present alternative stream cipher (Strike) inspired by the stochastic behaviour of lightning strike phenomena. The novelty originality Strike stem from utilisation as a source generating random keystreams decryption. consists three main functi...

During running, the foot collides with the ground approximately 1000 times per mile. These collisions vary significantly by the strike pattern that the runner adopts. A rearfoot strike pattern results in a very distinct vertical impact peak that is missing in a midfoot or forefoot strike landing (Figure 1) [1]. The impact peak of a rearfoot strike is associated with higher rates of loading comp...

We studied the defensive strike of one species of each of five recognized lineages within the genus Bothrops, namely, B. alternatus, B. jararaca, B. jararacussu, B. moojeni and B. pauloensis. The defensive strike of the studied species was in general similar to that of Crotalus viridis and C. atrox, but some important differences were observed. Bothrops alternatus and B. pauloensis struck prefe...

the increasing use of computers and the widespread use of networks, Social networking and use applications through the use of the Internet to make the spread images, which make it easy to be penetrated from the attacker and from everyone who try to change the information. So, the need arises to transmit the information securely through a secure manner . Steganography is the best solution to sol...
