1. Morphic detritus, including coarse particulate organic matter such as terrestrial tree leaves and wood, is consumed by few fishes in temperate stream systems but is ingested by abundant and diverse groups of specialized fishes in tropical rivers; physiological assimilation and partitioning of morphic detritus by fishes remain poorly understood. 2. This study examines seven species of Neotrop...

Reliance on plant exudates is a relatively rare dietary specialization among mammals. One well-studied example of closely related exudate feeders is the New World marmosets and tamarins. Whereas marmosets actively gouge tree bark with their incisors to stimulate the flow of sap, tamarins are opportunistic exudate feeders that do not gouge bark. Several studies of the dentaries and jaw adductors...

Exorbitant price increases for critical off-patent medicines have received considerable media attention in recent months, leading to an investigation by the U.S. Senate. However, much of this attention has focused upon the companies that initiated the price increases, all of whom had recently acquired the drugs in question. Overlooked are upstream interventions with the originators of these dru...

We present a precise approach to the generation of optimized collision-free and gouging-free tool paths for 5-axis CNC machining of freeform NURBS surfaces using flat-end and rounded-end (bull nose) tools having cylindrical shank. To achieve high approximation quality, we employ analysis of hyper-osculating circles (HOC) [26, 27], that have third order contact with the target surface, and lead ...
