We theoretically analyze the Cops and Robber Game for the first time in a multidimensional grid. It is shown that for an ndimensional grid, at least n cops are necessary to ensure capture of the robber. We also present a set of cop strategies for which n cops are provably sufficient to catch the robber. Further, for two-dimensional grid, we provide an efficient cop strategy for which the robber...

We present a decentralized heuristic applicable to multi-agent systems (MAS), which is able to solve multiple-choice combinatorial optimization problems (MC-COP). First, the MC-COP problem class is introduced and subsequently a mapping to MAS is shown, in which each class of elements in MC-COP corresponds to a single agent in MAS. The proposed heuristic ”COHDA” is described in detail, including...

Context-oriented Programming, or COP, provides programmers with dedicated abstractions and mechanisms to concisely represent behavioral variations that depend on execution context. By treating context explicitly, and by directly supporting dynamic composition, COP allows programmers to better express software entities that adapt their behavior late-bound at run-time. Our paper illustrates COP c...

A graph is bridged if it contains no isometric cycles of length greater than three. Anstee and Farber established that bridged graphs are cop-win graphs. According to Nowakowski and Winkler and Quilliot, a graph is a cop-win graph if and only if its vertices admit a linear ordering v1 , v2 , ..., vn such that every vertex vi , i>1, is dominated by some neighbour vj , j<i, i.e., every vertex vk ...

Ataxia is a neurological symptom characterized by abnormal movement, due to cerebellar malfunction. Although the cause of the malfunction varies, from mutations in calcium or potassium channels to progressive degeneration of cerebellar tissue, the neurological symptoms of cerebellar-related ataxia are similar. In this short review we present a model that portrays the olivo-cerebellar system as ...

Approximately one third of a cell's proteins are destined to function outside the cell's boundaries or while embedded within cellular membranes. Ensuring these proteins reach their diverse final destinations with temporal and spatial accuracy is essential for cellular physiology. In eukaryotes, a set of interconnected organelles form the secretory pathway, which encompasses the terrain that the...

INTRODUCTION Carbon monoxide poisoning (COP) is one of the leading causes of death from poisoning worldwide. There is no published study of COP in Singapore so far. MATERIALS AND METHODS All patients admitted with the diagnosis of COP to Tan Tock Seng Hospital (TTSH) over 5 years from 1999 to 2003 were retrospectively reviewed. The diagnosis was based on a history of potential exposure to car...

Copolymer 1 (Cop 1) is a synthetic basic random copolymer of amino acids that has been shown to be effective in suppression of experimental allergic encephalomyelitis and is being tested as a candidate drug for multiple sclerosis. It has been previously demonstrated that Cop 1 is immunologically cross-reactive with the autoantigen myelin basic protein (BP) and competitively inhibits the respons...

Ensuring that software can display different behavior in different use contexts requires adapting software at runtime in dynamically created scopes (e.g. in a thread, in a client session, in a collaboration). ContextOriented Programming (COP) offers dedicated language constructs for performing such dynamically scoped adaptations. COP supports powerful customizations such as concurrent customiza...

On the ideal bat, the sweet spot and COP locations would be coincident. This paper presents a combined experimental and finite element study into the relationship amongst the sweet spot, COP and vibration nodes of wood and aluminum baseball bats. Changes in mass distribution, material stiffness and wall thickness are explored to develop a fundamental understanding of the interaction between the...
