Visual experience relates the optically-specified environment to people’s ever-changing phenotype, which consists of their morphology, physiology, and behavior. Within near space, apparent distances are scaled with morphology, and in particular, to the extent of an actor’s reach. For example, we have found that the apparent distance to targets becomes foreshortened when a person holds a tool, w...

Mathematical models are emerging as important tools in the study of microbiology. As an illustrative example, we present results from several models each generated to study the interaction of Mycobacterium tuberculosis and the immune system. Different mathematical models were formulated on the basis of assumptions regarding system-component interactions, enabling us to explore specific aspects ...

Let $A$ and $B$ be two disjoint subsets of the vertex set $V$ of a graph $G$. The set $A$ is said to dominate $B$, denoted by $A rightarrow B$, if for every vertex $u in B$ there exists a vertex $v in A$ such that $uv in E(G)$. For any graph $G$, a partition $pi = {V_1,$ $V_2,$ $ldots,$ $V_p}$ of the vertex set $V$ is an textit{upper domatic partition} if $V_i rightarrow V_j$ or $V_j rightarrow...

Parts mating often requires the use of compliant motions, which cause an object in the grasp of a robot to slide along obstacles in its environment. This paper is about the interface between a compliant motion progra mming system and a compliant motion control system. We propose that in this interface the robot can be modeled as a damped spring. This model allows the programmin g system to spec...
