Ecology meets cancer biology: The cancer swamp promotes the lethal cancer phenotype
As they grow, tumors fundamentally alter their microenvironment, disrupting the homeostasis of the host organ and eventually the patient as a whole. Lethality is the ultimate result of deregulated cell signaling and regulatory mechanisms as well as inappropriate host cell recruitment and activity that lead to the death of the patient. These processes have striking parallels to the framework of ...
متن کاملFootpaths in the Stuff Swamp
This paper discusses stigmergy (i.e., the effect of communication through the environment) in relation to the Internet, especially with regard to World Wide Web-based learning. The paper begins by examining ways in which stigmergy occurs on the Web and then goes on to describe its use in the construction of a continually evolving system, CoFIND (Collaborative Filter In N Dimensions). CoFIND's p...
متن کاملPhylogeography and Domestication of Chinese Swamp Buffalo
To further probe into whether swamp buffaloes were domesticated once or multiple times in China, this survey examined the mitochondrial DNA (mtDNA) Control Region (D-loop) diversity of 471 individuals representing 22 populations of 455 Chinese swamp buffaloes and 16 river buffaloes. Phylogenetic analysis revealed that Chinese swamp buffaloes could be divided into two distinct lineages, A and B,...
متن کاملSwamp: an Isometric Frontend for Speaker Clustering
In this paper, we describe a non-linear feature normalization based on Riemannian differential geometry. This feature normalization will yield parameters that are invariant under any bijective stationary transformation. Moreover, it is robust to additive noise that is uncorrelated with speech and quasi-stationary. The only requirement is that of ergodicity. The frontend is called SWAMP (Sweepin...
متن کاملAuxin Action: Slogging out of the Swamp
How does auxin affect so many different aspects of plant growth and development? Recent evidence from localization of auxin efflux carriers and the effects of auxin on degradation of transcription factors has begun to reveal a possible mechanism for auxin action.
