Remark. The notation in condition (iii) reflects the possibility that ḣ might fail to exist at finitely many points. (Various alternative ways to deal with this possibility exist; none is completely satisfactory.) There is an obvious heierarchy in these concepts: every global minimizer also satisfies the criteria to lie in each of the local categories listed above. Any strong local minimizer is...

32 GHz observations with the Effelsberg 100-m telescope revealed a highly polarized Galactic Centre filament: G0.087−0.087, running parallel to the well-known Arc structure. It has a similar flat spectrum, but it is an order of magnitude weaker. G0.087−0.087 is about 2.5 or 6.2 pc long and located at the western boundary of the expanding molecular cloud G0.11−0.11. This unusual cloud is also vi...

Rho family GTPases have been implicated in neuronal growth cone guidance; however, the underlying cytoskeletal mechanisms are unclear. We have used multimode fluorescent speckle microscopy (FSM) to directly address this problem. We report that actin arcs that form in the transition zone are incorporated into central actin bundles in the C domain. These actin structures are Rho/Rho Kinase (ROCK)...

In this paper, we extend the language we proposed in [11] to make it possible to program arc-consistency algorithms. We also propose a hybrid algorithm that integrates the interval-consistency (IC) and arc-consistency (AC) algorithms. For a constraint, the algorithm checks IC when it is non-binary and checks AC when the constraint turns into binary. The algorithm is well-balanced. Its reduction...

Dual Consistency (DC) is a property of Constraint Networks (CNs) which is equivalent, in its unrestricted form, to Path Consistency (PC). The principle is to perform successive singleton checks (i.e. enforcing arc consistency after the assignment of a value to a variable) in order to identify inconsistent pairs of values, until a fixpoint is reached. In this paper, we propose two new algorithms...

The existing complete methods for solving Constraint Satisfaction Problems (CSPs) are usually based on a combination of exhaustive search and constraint propagation techniques for the reduction of the search space. Such propagation techniques are the local consistency algorithms. Arc Consistency (AC) and Generalized Arc Consistency (GAC) are the most widely studied local consistencies that are ...

Two sets of ultraviolet images of the Jovian north aurora were obtained with the Faint Object Camera on board the Hubble Space Telescope. The first series shows an intense discrete arc in near corotation with the planet. The maximum apparent molecular hydrogen emission rate corresponds to an electron precipitation of approximately 1 watt per square meter, which is about 30,000 times larger than...

A digraph obtained by replacing each edge of a complete multipartite graph by an arc or a pair of mutually opposite arcs with the same end vertices is called a semicomplete multipartite digraph. L. Volkmann (1998) raised the following question: Let D be a strong semicomplete multipartite digraph with a longest path of length l. Does there exist a strong spanning oriented subgraph of D with a lo...

In this paper we study the asymptotic behavior, as n → ∞, of ratios Dn(e hdμ)/Dn(dμ) of Toeplitz determinants defined by a measure μ and a sufficiently smooth function h. The approach we follow is based on the Verblunsky coefficients associated to μ. We prove that that the second order asymptotics depends on only few Verblunsky coefficients. In particular, we establish a relative version of the...

following our interest in reaching for a molded rubber article with possible detergent contact applications, durable silver nanopowder (agnp) is synthesized by arc discharge, then mixed with varying ratios of ethylene propylene rubber (epr), affording novel agnp@epr nanocomposites. x-ray diffraction (xrd) patterns of agnp as well as agnp@epr show no trace of impurity, while scanning electron mi...
