The energy absorbed in a light-harvesting protein complex is often transferred collectively through aggregated chromophore clusters. For population evolution of chromophores, the time-integrated effective rate matrix allows us to construct quantum kinetic clusters quantitatively and determine the reduced cluster-cluster transfer rates systematically, thus defining a minimal model of energy-tran...

Considerable attention has been paid to the hypothesis, advanced by Olson, that accumulations of interest groups build up over time and retard economic performance. Most previous tests of this hypothesis have been based on comparisons of growth rates. In this paper, it is argued that comparisons of income levels yield a superior test. Strong forms of the Olson hypothesis, in which shocks such a...

La descomposición del mantillo es un proceso fundamental para mantener la productividad primaria neta y fertilidad de los ecosistemas forestales. Por tal motivo, se realizó estudio en el ejido Pablillo, municipio Galeana, Nuevo León, México durante año conocer tres forestales clima templado (pino, encino pino-encino) que incluyó modelos predecir tasa descomposición. En cada ecosistema distribuy...
