Freuder 9] has previously given conditions that guarantee backtrack-free search when solving binary constraint networks. Freuder's condition relies on the \width" of the constraint network. Computing the width of a constraint network involves minimizing over all possible orderings of the vertices in the network. This paper presents an similar result for(More)
Both high and low ambient temperature represent thermal stressors that, among other physiological responses, induce activation of the hypothalamic-pituitary-adrenal (HPA) axis and secretion of arginine-vasopressin (AVP). The exposure to heat also leads to disturbance of osmotic homeostasis. Since AVP, in addition to its well-known peripheral effects, has(More)
In the hypothalamus, insulin takes on many roles involved in energy homoeostasis. Therefore, the aim of this study was to examine hypothalamic insulin expression during the initial phase of the metabolic response to fasting. Hypothalamic insulin content was assessed by both radioimmunoassay and Western blot. The relative expression of insulin mRNA was(More)
