BACKGROUND Inadequate reporting undermines findings of randomized controlled trials (RCTs). This study assessed and compared articles published in high-impact general medical and specialized journals. METHODS Reports of RCTs published in high-impact general and specialized medical journals were identified through a search of MEDLINE from January to March of 1995, 2000, 2005, and 2010. Article...

In spin-glass systems, frustration can be adjusted continuously and considerably, without changing the antiferromagnetic bond probability p, by using locally correlated quenched randomness, as we demonstrate here on hypercubic lattices and hierarchical lattices. Such overfrustrated and underfrustrated Ising systems on hierarchical lattices in d=3 and 2 are studied. With the removal of just 51% ...

A major challenge in neuroscience is to decipher the structural layout of the brain. The term "connectome" has recently been proposed to refer to the highly organized connection matrix of the human brain. However, defining how information flows through such a complex system represents so difficult a task that it seems unlikely it could be achieved in the near future or, for the most pessimistic...

RESUMO: Diversos sistemas computacionais desenvolvidos utilizando metodologias tradicionais como análise estruturada e essencial encontram-se em processo de evolução devido à necessidade de atender novos requisitos, do uso de novas tecnologias, de mudanças na metodologia de desenvolvimento, entre outras motivações. Neste processo, pouca ou nenhuma atenção tem-se dado ao aproveitamento de inform...

b a c k ground: csf is a clear liquid that its mechanical properties are to a large extent similar to water properties. regarding the lack of a numerical index for diagnosis of diseases resulting from increased csf pressure such as hydrocephalus, evaluation of hydrodynamic conditions of csf in cerebral ventricular system is of great importance. methods: at first, the diagram of velocity in sylv...
