The problem is to determine the number of ‘cops’ needed to capture a ‘robber’ where the game is played with perfect information, the different sides moving alternately. The cops capture the robber when one of them occupies the same vertex as the robber at any time in the game. A copwin graph is one in which one cop can always capture the robber. A graph is cop-win edge-critical with respect to ...

Although many researchers and practitioners have discussed different aspects of outsourcing in the past, there have been only a handful of papers that grapple these complex issues from a broad perspective. The main purpose of this study is to lay an integrative groundwork for the understanding of outsourcing, including its key research areas, its evolution, its theoretical models, and its futur...

PURPOSE To establish normative data for children on the Words-in-Noise Test (WIN; R. H. Wilson, 2003; R. H. Wilson & R. McArdle, 2007). METHOD Forty-two children in each of 7 age groups, ranging in age from 6 to 12 years (n=294), and 24 young adults (age range: 18-27 years) with normal hearing for pure tones participated. All listeners were screened at 15 dB HL (American National Standards In...

Let G be a finite connected graph of order at least two. Two players (a cop and a robber) are allowed to play a game on G according to the following rule: The cop chooses a vertex to stay then the robber chooses a vertex afterwards. After that they move alternately along edges of G, where the robber may opt to stay put when his turn to move comes. The cop wins if he succeeds in putting himself ...

The endocannabinoid system and the cannabinoid CB(1) receptors are involved in the development of ethanol tolerance and dependence. This study aimed to investigate the in vivo sensitivity of a CB(1) receptor agonist (WIN 55,212-2) modulating the synthesis of 3,4-dihydroxy-phenylalanine/dopamine/noradrenaline (DOPA/DA/NA) and that of 5-hydroxy-tryptophan/serotonin (5-HTP/5-HT) in rat brain after...

Cannabinoid CB1 receptor (CB1R) signaling system is extensively distributed in the vertebrate retina. Activation of CB1Rs regulates a variety of functions of retinal neurons through modulating different ion channels. In the present work we studied effects of this receptor signaling on K(+) channels in retinal ganglion cells by patch-clamp techniques. The CB1R agonist WIN55212-2 (WIN) suppressed...
