BACKGROUND:Global health research is essential for development. A major issue is the inequitable distribution of research efforts and funds directed towards populations suffering the world's greatest health problems. This imbalance is fostering major attempts at redirecting research to the health…

Since its discovery shortly after the International Geophysical Year, the terrestrial magnetosphere has been under intensive study with satellites and ground-based instrumentation. We have a fairly good picture of its main structural features and the dynamic behavior of its multiple…

References on historical and recent earthquakes in Oaxaca City, or that have caused in other localities of the Oaxaca state from 1542 until 1988, are reviewed. Macroseismic data are used to define sets of similar earthquakes. On the basis of…

Las competencias representan el despliegue de una forma de razón que anula el "yo pienso" y "cómo yo explico" que debe darse en el diálogo de saberes como expresión intersubjetiva. En este contexto, el proceso tradicional de evaluación está vinculado…

We show how to recover Euler's formula for $\zeta(2n)$, as well as $L_{\chi_4}(2n+1)$, for any integer $n$, from the knowledge of the density of the product $\mathbb{C}_1,\mathbb{C}_2\ldots,\mathbb{C}_k$, for any $k\geq 1$, where the $\mathbb{C}_i$'s are independent standard Cauchy variables.
