Weighted and controlled frames have been introduced recently to improve the numerical efficiency of iterative algorithms for inverting the frame operator. In this paper we develop systematically these notions, including their mutual relationship. We will show that controlled frames are equivalent to standard frames and so this concept gives a generalized way to check the frame condition, while ...

We offer a parsimonious definition of large population potential games, provide some alternate characterizations, and demonstrate the advantages of the new definition over the existing definition, but also show the equivalence of the two definitions.

It has been reported that gene expression directed by the long terminal repeat of Rous sarcoma virus (RSV) is trans activated by a protein encoded in an alternate reading frame within the RSV gag gene (S. Broome and W. Gilbert, Cell 40:537-546, 1985). We have made specific mutations to test the role of the putative transcriptional activator in RSV replication. Termination codons were created wi...

Objectives: To investigate the effect of comb-like slot dimensions on dualband microstrip antenna performance parameters. Methods: Alternate comblike slots are placed patch and varied to observe The design is simulated in Mentor Graphics software package. results verified with Finite Difference Time Domain (FDTD) analysis MATLAB. measured Vector Network Analyzer (VNA) good agreement results. Fi...

Adaptation to the acidic microenvironment, and adherence to mucosal epithelium, are essential for persistent colonization of the human stomach by Helicobacter pylori. The expression of SabA, an adhesin implicated in the ability of H. pylori to adhere to the host gastric epithelium, can be modulated by phase variation via slipped-strand mispairing in repetitive nucleotide tracts located in both ...

This work presents a quantitative framework for describing the overcompleteness of a large class of frames. It introduces notions of localization and approximation between two frames F = {fi}i∈I and E = {ej}j∈G (G a discrete abelian group), relating the decay of the expansion of the elements of F in terms of the elements of E via a map a : I → G. A fundamental set of equalities are shown betwee...

Whilst there has been considerable research into the potential uses of digital games in the classroom, there has been less investigation into the educational value of Alternate Reality Games (ARGs). Unlike console or computer games, in ARGs the game-world is constructed through a combination of onand off-screen media, and is created and shaped through dynamic dialogue between the designers and ...

We introduce an endofunctor H on the category baℓ of bounded archimedean ℓ-algebras and show that there is a dual adjunction between Alg(H) algebras for Coalg(V) coalgebras Vietoris V compact Hausdorff spaces. prove Gelfand duality lifts to equivalence full reflective subcategory Algu(H) Alg(H). provide alternate view by introducing Hu consisting uniformly complete objects showing Alg(Hu) isomo...
