In this paper, we show that in the best-known version of the blocks world (and several related versions), planning is difficult, in the sense that finding an optimal plan is NP-hard. However, the NP-hardness is not due to deleted-condition interactions, but instead due to a situation which we call a deadlock. For problems that do not contain deadlocks,(More)
PURPOSE Positron emission tomography (PET) is widely used for the staging evaluation of non-small-cell lung cancer; however, its use in small-cell lung cancer (SCLC) remains investigational. PATIENTS AND METHODS We did a retrospective study of 137 patients to evaluate the role of PET in SCLC. Fifty-one of 137 patients had computed tomography (CT) and PET(More)
BACKGROUND Iron deficiency anemia is the most common form of anemia in India. Hemoglobin A1c (HbA1c) is used in diabetic patients as an index of glycemic control reflecting glucose levels of the previous 3 months. Like blood sugar levels, HbA1c levels are also affected by the presence of variant hemoglobins, hemolytic anemias, nutritional anemias, uremia,(More)
This phase 3 pivotal study evaluated the safety, efficacy, and pharmacokinetics of a recombinant FVIII Fc fusion protein (rFVIIIFc) for prophylaxis, treatment of acute bleeding, and perioperative hemostatic control in 165 previously treated males aged ≥12 years with severe hemophilia A. The study had 3 treatment arms: arm 1, individualized prophylaxis(More)
UNLABELLED Given in clinically relevant large doses to rats, mu-opioids produce limbic system hypermetabolism and histopathology. This investigation extends these observations, in both rats and humans, for the short-acting drug remifentanil, which allows more precise control and assessment of the effects of duration of opioid exposure. We performed two(More)
Although blocks-world planning is well-known, its complexity has not previously been analyzed, and different planning researchers have expressed connicting opinions about its diiculty. In this paper, we present the following results: 1. Finding optimal plans in a well-known formulation of the blocks-world planning domain is NP-hard, even if the goal state(More)
Lymphatic filariasis is endemic in India. Out of 128 million infected individuals worldwide, India accounts for 48 million cases [Manson's Tropical Diseases, 21st Ed. p 1488]. Filariasis can have protean manifestations, but Tropical pulmonary eosinophilia and chyluria are unusual manifestations reported mainly from South Asian countries [Manson's Tropical(More)
We report the case of a 22-year-old woman who presented with acute onset flaccid quadriparesis. Physical examination showed mild pallor with cervical and axillary lymphadenopathy, hepatomegaly, and bilateral smooth enlarged kidneys. Neurological examination revealed lower motor neuron muscle weakness in all the four limbs with hyporeflexia and normal(More)
Computing an optical flow field using the classical image motion constraint equation $$I_x u + Iy\upsilon + I_t = 0,$$ is difficult owing to the aperture problem and the need to compute the image intensity derivatives via numerical differentiation—an extremely unstable operation. We integrate the above constraint equation over a significant spatio-temporal(More)
