In string theory, the brane world scenario, where the Standard Model gauge and matter fields live inside some branes while gravitons live in the bulk, can be a viable description of our universe. In this note we argue that the brane world actually is a likely description of nature. Our discussion includes a revisit of certain issues, namely, coupling unification, dilaton stabilization and super...

This article introduces a self-stabilizing deadlock-detection algorithm for the OR model. The algorithm is complete, because it detects all deadlocks, and it is correct, because it does not detect false deadlocks. Because of the self-stabilization property, the algorithm supports dynamic changes in the wait-for graph on which it works, and transient faults; also, it can be started in an arbitra...

A silent self-stabilizing asynchronous distributed algorithm, SSLE, for the leader election problem, in a connected unoriented network with unique IDs, is given. SSLE uses O(log n) space per process and stabilizes in O(n) rounds, where n is the number of processes in the network.

This paper has two objectives. First, it provides an overview of the vast literature on fiscal competition. A major theme is that the desirability of such competition depends in important ways on one’s view of how the public sector works. This is a complex issue with some intriguing twists. Second, the paper explores the emerging structure of the public sector in the European Union in the prese...

This paper discusses the synthesis of compensators for plants which can be represented using a Takagi-Sugeno (T-S) fuzzy model. The resulting compensator designs, called PDC controllers, are parameter dependent and mirror the structure of the T-S plant model. This paper extends the existing work on state feedback PDC controllers by introducing the notion of a dynamic PDC controller. The paper c...

We study stabilization of moduli in the type–IIB superstring theory on the six-dimensional toroidal orientifold T6/Ω · (−1)L · Z2. We consider background space-filling D9-branes wrapped on the orientifold along with non-Abelian fluxes on its world-volume and demonstrate with two examples that this can stabilize all the complex structure moduli and some of the Kähler moduli. kumar(at) iopb (dot)...

This paper is concerned with the quadratic stabilization for a class of switched nonlinear singular systems. For this class of switched systems, when each individual subsystem fails to be minimum-phase, the quadratic stabilization problem is solved via designing switching law. This extends available results for non-switched nonlinear singular systems.
