INTRODUCTION The reflection and refraction of horizontally polarized shear (SH) waves by a frictional contact interface that can slip has been studied by the present authors [l-3] and Miller [4-6]. If the solids are sheared, the localized slip induced by the waves is more pronounced in one direction than in the other, which leads to the interesting phenomenon of the solids creeping with respect...

If rock beats scissors and scissors beat paper, onemight assume that rock beats paper too. But this is not the case for intransitive relationships thatmake up the famous rock-paper-scissors game. However, the sole presence of papermight prevent rock frombeating scissors, simply because paper beats rock. This is the blueprint for the rock-paper-scissors gamewith protection spillovers, which has ...

the purpose of this study was to determine whether sectioning the cervical septum is associated with intraoperative bleeding, incompetent cervix, and secondary infertility. in this prospective observational study, fourteen women with complete septate uterus who had a history of repeated pregnancy loss and infertility were treated hysteroscopically. preoperative history included 35 pregnancies o...

In this paper, an analytical model for cutting process of a plate of material with a pair of scissors is presented. The cutting model predicts that, during task, force/torque responses of the scissors depend on the toughness and geometry of the plate. A force/position control law for a pair of scissors in contact with a partially known environment is proposed. The environment is a rigid plate o...

Algorithms for several emerging large-scale problems in cheminformatics have as their rate-limiting step the evaluation of relatively slow chemical similarity measures, such as structural similarity or three-dimensional (3-D) shape comparison. In this article we present SCISSORS, a linear-algebraical technique (related to multidimensional scaling and kernel principal components analysis) to rap...
