We present a practical meldable priority queue implementation. All priority queue operations are very simple and their logarithmic time bound holds with high probability, which makes this data structure more suitable for real-time applications than those with only amortized performance guarantees. Our solution is also space-eecient, since it does not require storing any auxiliary information wi...

Fecal extracts from a pregnant black rhinoceros, Diceros bicornis, were analyzed by radioimmunoassay, HPLC, and by GC-mass spectrometry. From 40 g of dried feces a total of 33 pregnanes in the C21O2 series, including a number of novel 17 epimers were identified. No progesterone was recovered. The principal progesterone metabolite by mass was 5 -pregnan-3 ,20 -diol (44.5%), which did not cross r...

Evidence that ovarian steroid hormones such as estrogen and progesterone affect cognition comes from studies of memory in older women receiving estrogen replacement therapy and studies of sexually dimorphic skills in young women across the menstrual cycle. Sixteen women (ages 18–28) completed tests of memory (implicit category exemplar generation, category-cued recall, implicit fragmented objec...

We present a reformulation of the Bristow±Campbell model for daily solar radiation, developed using daily observations of radiation, temperature, humidity, and precipitation, from 40 stations in contrasting climates. By expanding the original model to include a spatially and temporally variable estimate of clear-sky transmittance, and applying a small number of other minor modi®cations, the new...

priority setting of health interventions is generally considered as a valuable approach to support low- and middle-income countries (lmics) in their strive for universal health coverage (uhc). however, present initiatives on priority setting are mainly geared towards the development of more cost-effectiveness information, and this evidence does not sufficiently support countries to make optimal...

OBJECTIVE To describe priority setting for new technologies in medicine. DESIGN Qualitative study using case studies and grounded theory. SETTING Two committees advising on priorities for new technologies in cancer and cardiac care in Ontario, Canada. PARTICIPANTS The two committees and their 26 members. MAIN OUTCOME MEASURES Accounts of priority setting decision making gathered by revi...
