Heterogeneous computing technologies, such as multi-core CPUs, GPUs and FPGAs can provide significant performance improvements. However, developing applications for these technologies often results in coupling applications to specific devices, typically through the use of proprietary tools. This paper presents SHEPARD, a compile time and run-time framework(More)
Three experiments were performed to determine the effect of stress on the neuroendocrine-immune system in nonhuman primates. In Experiment 1 the diurnal variation in cell and hormone levels was determined. The percentages of neutrophils, monocytes, and eosinophils fluctuated throughout the 24-hr period, while white blood cell (WBC), neutrophil-to-lymphocyte(More)
The influence of piglet sensory systems and the role of odors from the sow's ventrum on piglet nipple attachment were investigated. In Experiment 1, four sows had their ventrum washed with organic solvents and four were unwashed control sows. Piglets were given one of four treatments shortly after birth: nares that were mechanically blocked (B), a lidocaine(More)
Lithium (Li) suppresses intraspecific aggression in rats and other mammals. However, antiaggressive doses of Li have been shown to produce signs of illness and to serve as an unconditioned stimulus for conditioned taste aversions (CTA). Therefore, it is possible that the antiaggressive effects of Li result from Li-induced malaise. Malaise and CTA's produced(More)
The present study investigated the question of how restraint affects the hypothalamo-pituitary adrenocortical axis and the hypothalamo-pituitary gonadal axis in intact, adult female rhesus macaques in both the follicular and luteal phases of the menstrual cycle. Restraint was chosen because it is not physically harmful to the animal but rather serves(More)
Continuous observations are an accurate method for behavioral measurements but are difficult to conduct on large numbers of animals because of extensive labor requirements. Thus, we sought to develop methods of behavioral data collection in feedlot cattle production systems that reasonably approximated continuous sampling. Standing, lying, feeding,(More)
The effects of intracerebroventricular (icv) administration of porcine corticotropin-releasing hormone (pCRH) and cortisol on the immune system and behavior were examined in domestic pigs. In Experiment 1, 50 micrograms of pCRH in 200 microliters of saline or 200 microliters of vehicle was administered i.c.v. at 0600 h. Blood samples were obtained at 0600(More)
Effects of pig birth (first 3-wk period) and rearing environments on growth and muscle quality characteristics of loins were evaluated in three experiments over seasons in west Texas and central Missouri. Housing systems included indoor slatted-floor buildings, indoor deep-bedded buildings, outdoor housing on dirt, and outdoor housing on alfalfa pasture.(More)
Abstract— This paper introduces an adaptive packet sampling mechanism for IP flow monitors that are incorporated into network elements. Such monitors have limited resources that can be rapidly exhausted by network attacks such as distributed denial-of-service (DDoS) and port scanning. The mechanism provides resilience against these types of network(More)
