An algorithm is described for finding the maximal weight chain between two points in a locally finite partial order under the restriction that all but • (or fewer) successive pairs in the chain belong to a given subset of the partial order relation. Applications of the method in molecular genetics, critical path scheduling, and other fields are discussed. Let P be a set with two locally finite ...

the information revolution is one of the important problem that affects many aspects our life. this revolution and it’s technology not only increase the actors in international relations but also creates the new rules and new space. because, this revolution and it’s political effects , the main purpose of this paper is the examination of international relations theories about this problem. so i...

One hundred and forty-four years elapsed between the publication of Copernicus’s De Revolutionibus, which opened the great scientific revolution of the XVII century, and the publication of Newton’s Principia, the final synthesis that brought that revolution to a spectacularly successful end. During those hundred and forty-four years, the basic grammar for understanding the physical world change...

In this paper, we construct surfaces of revolution with constant mean curvature H = c and minimal surfaces of revolution in hyperbolic 3-space H(−c) of constant sectional curvature −c. It is shown that surfaces of revolution with constant mean curvature H = c in H(−c) tend toward the catenoid, the minimal surface of revolution in Euclidean 3-space E as c → 0. Minimal surfaces of revolution in H...

the present paper studies the objectives and functions of constructing the new towns before and after the revolution in iran. before the revolution, new towns were established based on political – bureaucratic objectives, for the operation of huge oil resources and affiliated industries, to accommodate the workforce in industrial complexes, to implement the policy of regional decentralization...

Although ant ibodies against nuclear antigens are considered the hal lmark of systemic lupus e ry thematosus (SLE) 1, antibodies against cytoplasmic consti tuents have also been identified (1, 2). Despite their recogni t ion more than 25 years ago, the prevalence, antigenic specificities, and disease associations of antir ibosomal antibodies (ARA) are all controversial (3-10) . Since these prob...
