In this two-part paper, a common algebraic framework is introduced for the frozen-time analysis of stability and H"-optimization in slowly time-varying systems, based on the notion of a normed algebra on which local and global products are defined. Relations between local stability, local (near) optimality, lotal coprime factorization, and global versions of these properties are sought. The fra...

fasting is a common practice among people with diabetes (pwd). as healthcare providers we are in a position to assist those who choose to fast to manage their diabetes effectively. diabetes self-management education for pwd is needed both prior and during the time of fasting to best metabolic control.

Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...

Objective: Many studies have suggested that there is a relationship between coherence and cognitive processes. This study aims at investigating this hypothesis through assessing the relationship between cognitive variables and coherence in the discourse of two groups of Persian-speaking younger and older adults. Methods: In order to evaluate our participants' cognitive capabilities, we recrui...

We performed two-dimensional non-linear hydrodynamical simulations of two-component gravitating disks aimed at studying stability properties of these systems. In agreement with previous analytical and numerical simulations, we find that the cold gas component strongly affects the growth rates of the unstable global spiral modes in the disk. Already a five percent admixture of cold gas increases...
