‎Let $Omega$ be a class of unital‎ ‎$C^*$-algebras‎. ‎We introduce the notion of a local tracial $Omega$-algebra‎. ‎Let $A$ be an $alpha$-simple unital local tracial $Omega$-algebra‎. ‎Suppose that $alpha:Gto $Aut($A$) is an action of a finite group $G$ on $A$‎ ‎which has a certain non-simple tracial Rokhlin property‎. ‎Then the crossed product algebra‎ ‎$C^*(G,A,alpha)$ is a unital local traci...

Polymeric materials bearing polar groups constitute a class of macromolecules with interest in number uses. Because the direct synthesis employing polymerization strategies from monomers is very often precluded by catalyst poisoning or uncontrolled side reactions, alternative postpolymerization route consisting modifying previously prepared polymer continuously progressing. However, such poster...

Our work in carbon-microelectromechanical systems (C-MEMS) suggests that C-MEMS might provide a very interesting material and microfabrication solution to the battery miniaturization problem, active DNA arrays and a wide variety of chemical and biological sensors. We established that it is possible to use C-MEMS to create very high aspect ratio carbon structures (e.g. posts with an aspect ratio...

In this paper, we study the game-theoretic and computational repercussions of Henkin’s partially ordered quantifiers [19]. After defining a gametheoretic semantics for these objects, we observe that tuning the parameter of absentmindedness gives rise to quantifier prefixes studied in [28]. In the interest of computation, we characterize the complexity class PNP q in terms of partially ordered q...

This article presents a view of the relationship between K&R C’s most prominent descendants: ISO C and ISO C++. It gives a rough chronology of the exchanges of features between the various versions of C and C++ and presents some technical details related to their most significant current incompatibilities. My focus here is the areas where C and C++ differ slightly (‘‘the incompatibilities’’), r...

In this article, the complexes [Rh(Binor-S )(PR3)][BAr4] (R iPr, Cy, C5H9) are described. A combination of x-ray crystallography, NMR spectroscopy, density functional theory, and ‘‘atoms in molecules’’ calculations unequivocally demonstrates that the complexes contain rare examples of metal C–C agostic interactions. Moreover, they are fluxional on the NMR time scale, undergoing rapid and revers...
