This paper present two variable ordering methods for minimizing Reduced Ordered Binary Decision Diagrams (ROBDDs). The broad formal techniques, based on graph topology, and the details of the algorithms are suitable for further work on other algorithms of the same family. Experiments have shown that the algorithms improve on common algorithms for the majority of benchmark circuits.

Takayasu's arteritis (TA) is a chronic inflammatory disease of unknown cause. Stroke as a initial presentations without any systemic symptoms are rare. We had two cases of Takayasu's arteritis whose initial presentation were stroke without any significant systemic symptoms. So early detection and initiation of treatment lessens the chance of progression of disease and involvement of other organ...

Pheochromocytoma presents with headache, sweating, and palpitations associated with hypertension, heart failure, and arrhythmias due to catecholamine secretion.1 The presence of sustained ventricular tachycardia (VT) has been reported rarely.2,3 We describe a case of pheochromocytoma that manifested as sustained and incessant monomorphic VT. A 47-year-old woman with diabetes and hypertension un...

The object of study of the present paper may be considered as a model, in an elementary topos with a natural numbers object, of a non-classical variation of the Peano arithmetic. The new feature consists in admitting, in addition to the constant (zero) s0 2 N and the unary operation (the successor map) s1 : N ! N, arbitrary operations su : N u ! N of arities u `between 0 and 1'. That is, u is a...
