An Integrated and Evolutionary Dynamical Systems View of Climate Complexity

引用

International Journal of Geosciences 2013年第1期4卷 49-57页

作者： Walter Ritter Ortíz lorena cruz Sección de Bioclimatología Centro de Ciencias de la Atmósfera UNAM Circuito Interior s/n Ciudad Universitaria Coyoacan México

The Earth shows a constant display of an organized complexity system, and its intrinsic capacity for sporadic self-organization constitutes its fundamental and profound mysterious property. A graphical method derived from the logistic phase space of precipitation is proposed to identify periods of abundance-scarcity of rain as well as El Nino presence in order to cope with climate change. The most striking result is that the majority of El Nino events on this graph are chaotic, in which the sign of the dominant eigenvalues of precipitation gives trends of scarcity on negative signs and abundance on positive signs, with eleven years periods.

作者： Sonja Menge lorena Decker Axel Freischmidt Department of Neurology Ulm University89081 UlmGermany

In a recent study published in Science,Baughn et *** that TDP-43 acts as a steric block in STMN2 pre-mRNA processing preventing inclusion of a deleterious cryptic exon,and present strategies for substituting this function to compensate for the loss of nuclear TDP-43 in a variety of neurodegenerative diseases(NDs)including amyotrophic lateral sclerosis(ALS).1 Stathmin-2(STMN2)is a microtubule-associated protein speci-fically expressed in neurons and required for axon outgrowth and maintenance,as well as for axon regeneration after injury in vitro.
