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)
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 formulationof the blocks-world planning domain is NP-hard, even if the goal state is(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)
The complex relationships between organizational practices have been the focus of information technology business value (ITBV) research in recent years. There appears to be a discernible trend toward a more nuanced view in which the effects of information technology (IT), various organizational practices and their relationships are systematically(More)
A retrospective analysis of 108 cases of primary germ cell tumours of testis seen over a 6 year period at Institute Rotary Cancer Hospital of All India Institute of Medical Sciences, New Delhi is presented. There were 45 (42%) cases of seminoma and 63 (48%) of non-seminomatous germ cell tumours (NSGCT). The median age at presentation was 35 and 30 years(More)
In this paper, a neural network model is proposed which can be used for designing any monopole antenna whose element is square shaped and required to exhibit a wide band characteristics. All the antennas designed using this model shows a wideband response between 4.5 GHz - 5 GHz. This model is prepared using Feed Forward Back Propagation Algorithm. The(More)
Twenty-four out of 164 (14%) adult patients with primary germ cell tumours of testis seen over the last 6 years at the Institute Rotary Cancer Hospital (IRCH) of the All India Institute of Medical Sciences (AIIMS), New Delhi, were found to have cryptorchidism. Only one patient had undergone correction. As a result the testes were intra-abdominal in the vast(More)
Background. Tuberculosis of the liver without active pulmonary or miliary tuberculosis is considered as an uncommon diagnosis. The aim of the present study was to determine the etiological role of tuberculosis in adult patients presenting with features of liver abscess. Methods. A total of 40 patients with liver abscess were included in the study. The liver(More)
