Left-right symmetrical distal limb conformation can be an important prerequisite for a successful performance, and it is often hypothesized that asymmetric or uneven feet are important enhancing factors for the development of lameness. On a population level, it has been demonstrated that uneven footed horses are retiring earlier from elite level competition, but the biomechanical consequences a...

Cracks in thin layers are influenced by what lies beneath them. From buried craters to crocodile skin, crack patterns are found over an enormous range of length scales. Regardless of absolute size, their substrates can dramatically influence how cracks form, guiding them in some cases, or shielding regions from them in others. Here we investigate how a substrate's shape affects the appearance o...

Racism may well be an affect of despair. Racism may also be a central cause of despair. A telephone survey in the states of Queensland and NSW (sample 5056) examined the extent and distribution of experiences of racism. About 15 percent of Australians have experienced racism within the workplace and in education. About one-quarter of Australians report the experience of ‘everyday racisms’, such...

For production of high quality grape berries, the whole cluster should ripen at one time. The lack of uniform ripening within a cluster is termed "uneven ripening," and is characterized by the presence of green berries in an otherwise mature ripe cluster. Uneven ripening of 'Concord' is a major problem in the South, often prohibiting production. Northwest Arkansas is the southern boundary for c...

Let μ1, . . . , μn be continuous probability measures on Rn and α1, . . . , αn ∈ [0, 1]. When does there exist an oriented hyperplane H such that the positive half-space H+ has μi(H) = αi for all i ∈ [n]? It is well known that such a hyperplane does not exist in general. The famous ham sandwich theorem states that if αi = 2 for all i, then such a hyperplane always exists. In this paper we give ...

quadruped robots have unique capabilities for motion over uneven natural environments. this article presents a stable gait for a quadruped robot in such motions and discusses the inverse-dynamics control scheme to follow the planned gait. first, an explicit dynamics model will be developed using a novel constraint elimination method for an 18-dof quadruped robot. thereafter, an inverse-dynamics...
