The SNMP evolution: lost on simplicity or on functionality
The SNMP framework has gained a new stimulus with the efficient emergence of the third version (SNMPv3). Beyond its enrichments, namely the security model, the enormous base of legacy knowledge and legacy systems leads the SNMP management framework to a necessary choice in nowadays management scenarios. However, its services correspond roughly to low-level operations for setting or retrieving n...
متن کاملThe evolution of migration in a seasonal environment.
Despite the fact that migration occurs in a wide variety of taxa worldwide, little is known about the conditions under which migration is expected to evolve from an ancestral resident population. We develop a model that focuses on ecological factors affecting the evolution of migration in a seasonal environment within a genetically explicit framework. We model the evolution of migration for two...

15 صفحه اولSeasonal and spatial evolution of albedo in a snow-ice-land-ocean environment
[1] In the course of a program studying Arctic coastal processes we have investigated the albedos for the range of surfaces in the region and their response to seasonal changes in a land-ice-ocean regime near Barrow, Alaska. From April through June in the years 2000, 2001, and 2002, spectral and wavelength-integrated albedos were measured along 200-m survey lines. These lines were installed at ...
متن کاملRescue of social motility lost during evolution of Myxococcus xanthus in an asocial environment.
Replicate populations of the social bacterium Myxococcus xanthus underwent extensive evolutionary adaptation to an asocial selective environment (liquid batch culture). All 12 populations showed partial or complete loss of their social (S) motility function after 1,000 generations of evolution. Mutations in the pil gene cluster (responsible for type IV pilus biogenesis and function) were found ...
