We consider the minimum order graphs with a given cop number k, and we focus especially on the cases k = 2, 3. We prove that the minimum order of a connected graph with cop number 3 is 10, and show that the Petersen graph is the unique isomorphism type of graph with this property. We provide the results of a computational search on the cop number of all graphs up to and including order 10. A re...

OBJECTIVE To determine the cost of medical attention associated with traffic accidents in Bogotá, Colombia. METHODS Prospective observational study with data from adult patients attended to in the emergency centers of 6 hospitals. RESULTS Average total cost per patient was $1'112.000 COP. Average daily cost of hospitalized patients was $1'200.000 COP. Average cost of ambulatory treated pati...

A graph G is given and two players, a cop and a robber, play the folioking game: the cop chooses a vertex, then the robber chooses a vertex, then the players move alternately beginning with the cop. A move consists of staying at one’s present vertex or moving to an adjacent vertex; each move is seen by both players. The cop wins if he manages to occupy the same vertex as the robber, and the rob...

Knowledge Management (KM) on its surface may appear to be a dichotomous dis-synchronization with Community of Practice (CoP) development. KM is systematic and intentional, and presumes the defined body of facts. CoP, on the other hand, is based, as its name intends, on skill-based practice. It is the above oversimplified definition, though, that prompted the case study referred to herein. CoP b...

The purpose of this study was to examine the characteristics of centre of pressure (COP) and centre of mass (COM) fluctuations in ballet dancers standing quietly. Ten healthy young women performing classic ballet dance as recreational exercise (dancer group) and 10 healthy non-ballet dancers young women who were not ballet dancers (control group) participated in this study. Participants were in...

BACKGROUND Postural control deficits in individuals with Autism Spectrum Disorders (ASD) are widely acknowledged; however, the underlying biomechanical features of these deficits remain unknown. Nonlinear analyses provide insight into the nature of how movement is controlled and have the potential to provide new insight into the postural control abnormalities associated with ASD. The purpose of...

We present an efficient algorithm that computes the optimal strategy for cop in the game of Cop v.s. Gambler where the gambler’s strategy is not optimal but known to the cop. The algorithm runs inO(|V (G)||E(G)|) time.

The cDNA encoding epsilon-COP, the 36-kD subunit of coatomer, was cloned from a bovine liver cDNA library and sequenced. Immunoblotting with an anti-epsilon-COP antibody showed that epsilon-COP exists in COP-coated vesicles as well as in the cytosolic coatomer. Using the cloned cDNA, recombinant His6- tagged epsilon-COP was overexpressed in cultured Chinese hamster ovary (CHO) cells, from which...

Background Foot types (e.g. pronated, supinated foot) are used for clinical reasoning [1] and widely assumed to be related to centre of pressure (COP) patterns [2,3]. Specifically, a pronated foot will demonstrate a medially deviated COP. It follows that COP could be a measure of foot type and inferences about function extrapolated from it. The purpose of this study was to investigate whether C...

The Nintendo Wii balance board (WBB) has generated significant interest in its application as a postural control measurement device in both the clinical and (basic, clinical, and rehabilitation) research domains. Although the WBB has been proposed as an alternative to the "gold standard" laboratory-grade force plate, additional research is necessary before the WBB can be considered a valid and ...
