The existence of a Kodaira fibration, i.e., of a fibration of a compact complex surface S onto a complex curve B which is a differentiable but not a holomorphic bundle, forces the geographical slope ν(S) = c 1 (S)/c2(S) to lie in the interval (2, 3). But up to now all the known examples had slope ν(S) ≤ 2 + 1/3. In this paper we consider a special class of surfaces admitting two such Kodaira fi...

objective: preventing communicable diseases in the armed forces (af) of a country is considered as a national interest and has a great importance. there are limited data on the efficacy of vaccination of the navy personnel. this study was designed to evaluate both the safety and the immunogenicity of a recombinant hepatitis b (hb) vaccine made by pasteur institute of iran (ipi-rhb), in this tar...

HB and HB+ are a shared secret-key authentication protocols designed for low-cost devices such as RFID tags. HB+ was proposed by Juels and Weis at Crypto 2005. The security of the protocols relies on the learning parity with noise (LPN) problem, which was proven to be NP-hard. The best known attack on LPN by Levieil and Fouque [13] requires subexponential number of samples and sub-exponential n...

objective(s):typhoid fever is a dreadful disease of a major threat to public health in developing countries. vaccination with bacterial immunodominant components such as surface proteins may prove as a potent alternative to live attenuated vaccines. invh, an important part of needle complex in type three secretion system (ttss) plays important role in efficient bacterial adherence and entry int...

Previous findings, viz. that mice can be successfully immunized against infection with Salmonella dublin with either live or inactivated vaccine, were confirmed. Immunity lasted for at least 12 weeks in mice which had been immunized with inactivated alum-precipitated vaccine. The immunogenicity of inactivated vaccine gradually decreased on storage at 4 degrees C, but this was only detectable if...

Resumo Em Visão Computacional e Processamento de Imagens, uma das técnicas bastante utilizadas para realizar a decomposição de uma imagem em diferentes ńıveis de resolução consiste na criação de uma pirâmide de imagens. Neste trabalho é apresentada a teoria de pirâmides, acompanhada por diversos exemplos de decomposições piramidais e suas propriedades. Algumas aplicações que utilizam estruturas...

We describe haematological and DNA characterization of haemoglobinopathies in Thai adolescents caused by compound heterozygosities for Hb E [beta26(B8) Glu-Lys] and two other beta-globin chain variants, Hb Pyrgos [beta83(EF7) Gly-Asp] and Hb J Bangkok [beta56(D7) Gly-Asp]. Hb analysis demonstrated that although these two beta-chain variants have separated elution profiles on liquid chromatograp...
