Given a tournament T = (X, A), we consider two tournament solutions applied to T: Slater’s solution and Copeland’s solution. Slater’s solution consists in determining the linear orders obtained by reversing a minimum number of directed edges of T in order to make T transitive. Copeland’s solution applied to T ranks the vertices of T according to their decreasing out-degrees. The aim of this pap...

despite a lot of efforts and investigations worldwide, dnr is still a controversial issue in many countries. in iran although significant achievements are reached in different fields; end of life care is hardly considered as a scientific necessity. development and implementation of clear policies for dnr orders is required to prevent futile prolongation of death, psychological stress to the pat...

Autocatalytic activation of initiator caspases is the link between pro-apoptotic signals and the destruction machinery of apoptosis. Activation of caspase-9, which mediates oncogene and drug-induced apoptosis, requires binding to the protein APAF-1. We found that the proteolytic activity of caspase-9 in a complex with APAF-1 is several orders of magnitude higher than that of the free enzyme. Th...

OBJECTIVES To evaluate the feasibility of midnight routine blood draws and assess their impact on test result availability and stat laboratory orders. METHODS We changed the timing of routine blood draws from early morning to midnight on five inpatient wards during the period November 16 to 30, 2011. RESULTS For the entire institution, of all orders placed each day, laboratory test orders p...

Table 6: The best orders of the S-boxes (p = 2 ?48). 6 Appendix This appendix describes 136 orders of DES S-boxes for which the maximal probability of two-round iterative characteristics is as in DES or smaller. Table 6 describes the orders whose best characteristics have probability 2 ?48 , which is lower than the best characteristic of DES. Table 7 describes the orders whose best characterist...

We describe Abello’s acyclic sets of linear orders [1] as the permutations visited by commuting equivalence classes of maximal reduced decompositions. This allows us to strengthen Abello’s structural result: we show that acyclic sets arising from this construction are distributive sublattices of the weak Bruhat order. This, in turn, shows that Abello’s acyclic sets are, in fact, the same as Cha...

Pairwise nonisomorphic directed and hybrid triple systems can be generated by, respectively, directing and ordering twofold triple systems and using the automorphisms of the twofold triple systems for isomorph rejection. Using this approach directed triple systems of order up to 10 and hybrid triple systems of order up to 9 are classified. In particular, it turns out that the number of nonisomo...

This note presents the study of the conjugacy classes of elements of some given finite order n in the Cremona group of the plane. In particular, it is shown that the number of conjugacy classes is infinite if n is even, n = 3 or n = 5, and that it is equal to 3 (respectively 9) if n = 9 (respectively 15), and is exactly 1 for all remaining odd orders. Some precise representative elements of the...
