Everybody would agree that vision guides locomotion; but how does vision influence choice when there are different solutions for possible foot placement? We addressed this question by investigating the impact of perceptual grouping on foot placement in humans. Participants performed a stepping stone task in which pathways consisted of target stones in a spatially regular path of foot falls and ...

Network attackers frequently use a chain of compromised intermediate nodes to attack a target machine and maintain anonymity. This chain of nodes between the attacker and the target is called a stepping stone chain. Various classes of algorithms have been proposed to detect stepping stones, timing correlation based algorithms being a recent one that is attracting significant research interest. ...

The combined edges systems, which are the work’s central idea, used to introduce and investigate C-space in this paper. We crucial necessary stepping stone for concepts of c-derived graphs, c-closed c-closure.

Results for mutation, selection, genetic drift, and migration in a one-dimensional continuous population are reviewed and extended. The population is described by a continuous limit of the stepping stone model, which leads to the stochastic Fisher-Kolmogorov-Petrovsky-Piscounov equation with additional terms describing mutations. Although the stepping stone model was first proposed for populati...
