A hierarchy of pairwise commuting Hamiltonians for the quantum periodic Benjamin–Ono equation is constructed by using the Lax matrix. The eigenvectors of these Hamiltonians are Jack symmetric functions of infinitely many variables x1, x2, . . .. This construction provides explicit expressions for the Hamiltonians in terms of the power sum symmetric functions pn = x n 1 + x n 2 + · · · and is ba...

This paper actualizes the importance of psychological diagnostics children’s preparedness to attend school. The authors consider problem diagnosing foreign-speaking children study at a Russian school, analyze modern complexes, provide recommendations on choosing methods bilingual children, as well point out issues discovered in process interaction with children. Empirical evidence presented inc...

V E N O U S THROMmSIS HAS BEEN A W N troversial subject since John Hunter, in 1786, and Jean Cruveilhier, some 50 years later, enunciated the doctrine that "phlebitis dominates all pathology." VUchow, in 1846, aided by study with the m i m o p e , stated that the predisposing conditions to venous thrombosis were: "inflammatory or degenerative changes in the v e l wall, chemical or physical chan...

Two major classes of chromosomally encoded Escherichia coli pili have been defined functionally by their receptor specificities. Common pili are termed "mannose-sensitive" (MS). They bind Tamm-Horsfal l uromucoid and their agglutination of guinea pig erythrocytes is inhibited by o-mannose. In contrast, mannose-resistant (MR) pili agglutinate human erythrocytes in the presence of D-mannose. Most...

We present a top-down lower bound method for depth 3 AND-OR-NOT circuits which is simpler than the previous methods and in some cases gives better lower bounds. In particular we prove that depth 3 AND-OR-NOT circuits that compute PARITY resp. MAJORITY require size a t least 20.6 18.. fi resp. 2°.849...fi. This is the first simple proof of a strong lower bound by a top-down argument for non-mono...
