Abstract This research evaluated the effects of supplementing extruded dried distillers’ grains (DDG) cubes to grazing steers on subsequent finishing performance and carcass characteristics. Steers (n = 140) grazed tall fescue (Festuca arundinacea)/bermudagrass (Cynodon dactylon) pastures from 14 April 17 September 2020 with supplementation treatments 3 pastures/treatment) that included: 1) Fer...

Current Navy implementation of statutory requirements for naval surface combatants dictates the performance of a ship shock trial in order to determine the vulnerability of a ship to an underwater explosion (UNDEX) non-contact shock threat environment. The shock trial features a series of shots, typically three to four, at increasing levels of severity culminating in a two-thirds ship design le...

During World War II many surface combatants were damaged or severely crippled by close-proximity underwater explosions from ordnance that had actually missed their target. Since this time all new classes of combatants have been required to conduct shock trial tests on the lead ship of the class in order to test the survivability of mission essential equipment in a severe shock environment. Whil...

The amount of spill code generated by a compiler backend has crucial effects on program performance. Instruction scheduling before register allocation may cause live range overlaps that lead to suboptimal spill code. Even when a local scheduler tries to minimize register usage, its results can leave room for improvement regarding overall spill costs. We present Register Reuse Scheduling (RRS), ...

The emerging field of discrete differential geometry (DDG) studies discrete analogues of smooth geometric objects, providing an essential link between analytical descriptions and computation. In recent years it has unearthed a rich variety of new perspectives on applied problems in computational anatomy/biology, computational mechanics, industrial design, computational architecture, and digital...

The feed, labor, and equipment costs of developing heifers in a confined feeding system are relatively high. High Plains beef producers can reduce input costs by developing heifers on dormant native range; however, heifers are typically unable to consume sufficient crude protein (CP) from the low-quality (< 7% CP) forage base. Insufficient dietary protein reduces forage digestion and performanc...

Let G be a finite group and k be a field of characteristic p. We investigate the homotopy category K(Inj kG) of the category C(Inj kG) of complexes of injective (= projective) kG-modules. If G is a p-group, this category is equivalent to the derived category Ddg(C(BG; k)) of the cochains on the classifying space; if G is not a p-group it has better properties than this derived category. The ord...
