Many stock exchanges set up certain limits on the maximum variation that a stock is allowed to have in a single day. Table 1 gives an overview of the price limit rules of some of the world exchanges. As reflected in the table, among stock exchanges in 41 countries that we obtain information, 23 of them have price limits and 7 of them have some kinds of circuit breaker rules. The normal assertio...

We prove that in the biased (1 : b) Hamiltonicity Maker-Breaker game, played on the edges of the complete graph Kn, Maker has a winning strategy for b(n) ≤ ( 1− 30 ln n ) n lnn , for all large enough n.

The requirements to switching the capacities of SF6 circuit breakers submitted by Russian Grid companies are difficult satisfy. first limitation is related material and financial costs in order create a new requirement-satisfying device. second dictated necessity calculating complex physical processes braker interrupter during fault–current making or breaking before creating prototype. latter t...

Flavivirus nonstructural protein 2A (NS2A) is a component of the viral replication complex that functions in virion assembly and antagonizes the host immune response. Although flavivirus NS2A is known to associate with the endoplasmic reticulum (ER) membrane, the detailed topology of this protein has not been determined. Here we report the first topology model of flavivirus NS2A on the ER membr...
