Diierent Capacities of a Digraph Jj Anos Kk Orner

The Shannon capacity of every induced subgraph of a perfect graph equals its clique number. However, for the co{normal powers of an odd cycle the super{multiplicativity of the clique number makes the determination of capacity one of the hardest problems in combinatorics. We study the asymptotic growth of induced subgraphs of some particular type in powers of a xed graph. In case of a simple gra...

Seguimento de 11 pacientes com transtorno bipolar por cinco anos

Objective: To study the long-term follow-up of patients with bipolar disorder (BPD). Method: Eleven outpatients with BPD type I were followed up naturalistically for five years at a university teaching hospital. The Clinical Global Impression Scale (BPD version) was used to evaluate the occurrence of affective episodes, and the Strauss-Carpenter Outcome Scale was used to evaluate social and occ...

Biclique cryptanalysis of MIBS-80 and PRESENT-80 block ciphers

In this paper we present the first biclique cryptanalysis of MIBS block cipher and a new biclique cryptanalysis of PRESENT block cipher. These attacks are performed on full-round MIBS-80 and full-round PRESENT-80. Attack on MIBS80 uses matching without matrix method and has a data complexity upper bounded by 252 chosen plaintext where it reduced security of this cipher about 1 bit. Attack on PR...
