Como numerosos procesos biológicos, la proliferación de diversas poblaciones celulares animales presenta un ritmo circadiano. La respuesta diferencial a la ciclofosfamida ha sido relacionada con la periodicidad mitóti...

Escrito con una dosis de ironía, busca en el texto la respuesta a la pregunta formulada. El autor señala lo efímero de la teoría sobre el Nuevo Orden Mundial, el regreso al Siglo XIX que significa el "Fin de la Histo...

Por una legítima inquietud: reconocer el derecho a la información, y el compromiso por la educación, que trasciende lo biológico, tradicionalmente vinculado a lo genital-reproductivo, para transformarse en lo más pe...

We derive a new self-organizing learning algorithm that maximizes the information transferred in a network of nonlinear units. The algorithm does not assume any knowledge of the input distributions, and is defined here f...

Donoho and Johnstone (1994) proposed a method for reconstructing an unknown function f on [0,1] from noisy data d/sub i/=f(t/sub i/)+/spl sigma/z/sub i/, i=0, ..., n-1,t/sub i/=i/n, where the z/sub i/ are independent and...

Abstract Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in many industrial applications. In this paper we propose that an innovative new cla...

The carrier collection efficiency (η c ) and energy conversion efficiency (η e ) of polymer photovoltaic cells were improved by blending of the semiconducting polymer with C 60 or its functionalized derivatives. Compos...

BACKGROUND: Data were obtained on the general population epidemiology of DSM-III-R posttraumatic stress disorder (PTSD), including information on estimated life-time prevalence, the kinds of traumas most often associated...

A high-capacity system was developed to monitor the expression of many genes in parallel. Microarrays prepared by high-speed robotic printing of complementary DNAs on glass were used for quantitative expression measureme...

The Behavioral Model of Health Services Use was initially developed over 25 years ago. In the interim it has been subject to considerable application, reprobation, and alteration. I review its development and assess its ...
