compactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولSelf-renewal versus transformation: Fbxw7 deletion leads to stem cell activation and leukemogenesis.
Recent reports have demonstrated that specific tumor suppressors are important for both maintaining hematopoietic stem cell (HSC) quiescence and preventing leukemia development, suggesting a connection between these two activities. Matsuoka and colleagues (pp. 986-991) have further illustrated this theme by demonstrating that inactivation of the tumor suppressor Fbxw7 leads to HSC depletion by ...
متن کاملTRANSFORMATION SEMIGROUPS AND TRANSFORMED DIMENSIONS
In the transformation semigroup (X, S) we introduce the height of a closed nonempty invariant subset of X, define the transformed dimension of nonempty subset S of X and obtain some results and relations.
متن کاملNote on Fuzzy Random Renewal Process and Renewal Rewards Process
Recently, Zhao et al. [Fuzzy Optimization and Decision Making (2007) 6, 279-295] characterized the interarrival times as fuzzy random variables and presented a fuzzy random elementary renewal theorem on the limit value of the expected renewal rate of the process in the fuzzy random renewal process. They also depicted both the interarrival times and rewards are depicted as fuzzy random variables...
متن کاملSelf-renewal and differentiation
The adult human heart has limited regenerative capacity and, theref fore, functional restoration of the damaged heart presents a great challenge. Despite the progress achieved in the pharmacological and surgical treatment of degenerative myocardial diseases, they are still considered a major cause of morbidity and mortality in the western world. Repopulation of the damaged heart with cardiomyof...
