Tree-structured neural networks exploit valuable syntactic parse information as they interpret the meanings of sentences. However, they suffer from two key technical problems that make them slow and unwieldy for large-scale NLP tasks: they usually operate on parsed sentences and they do not directly support batched computation. We address these issues by(More)
We consider partially observable Markov decision processes (POMDPs) with a set of target states and every transition is associated with an integer cost. The optimization objective we study asks to minimize the expected total cost till the target set is reached, while ensuring that the target set is reached almost-surely (with probability 1). We show that(More)
OBJECT The Internet has become a widespread source for disseminating health information to large numbers of people. Such is the case for spine surgery as well. Given the complexity of spinal surgeries, an important point to consider is whether these resources are easily read and understood by most Americans. The average national reading grade level has been(More)
PURPOSE Recent structural and histochemical data from our laboratory indicate that human drusen often possess distinct, structural core domains. A similar, corelike structure is frequently noted clinically in some drusen-related conditions. To assess the nature of the corelike structures observed clinically, we evaluated color photographs and fluorescein(More)
OBJECTIVE To study the efficacy of isolated pharmaco-mechanical thrombolysis-thrombectomy (IPMT) by Trellis device (Covidien, Mansfield, MA) in managing acute limb ischemic (ALI). BACKGROUND ALI is both life and limb threatening disease with a reported 9-15% mortality and 15-25% limb loss in the first month after presentation. Pitfalls of current(More)
The effect of the administration of 3.5 g of psyllium husk twice daily for 90 days was investigated in 24 patients of non insulin dependent diabetes mellitus (NIDDM) with hyperlipidaemia. After 90 days of treatment, psyllium was withdrawn and the patients were followed up for a further 90 days. Psyllium significantly decreased the levels of total(More)
Acute aortofemoral graft occlusion is often effectively treated with endovascular therapy but a substantial proportion of patients experience failure or complications of this therapy, and most of them require definitive surgery for the underlying inflow, outflow, or graft disease. We describe a case of an aortofemoral graft occlusion that was successfully(More)
