This paper dedicates to exploring and exploiting the hidden resource in wireless channel. We discover that the stochastic dependence in wireless channel capacity is a hidden resource, specifically, if the wireless channel capacity bears negative dependence, the wireless channel attains a better performance with a smaller capacity. We find that the dependence in wireless channel is determined by...

This paper initiates the analysis of relation between evacuation time and group size by applying an extended floor-field cellular automaton model. Multi-speed-agents, a structure containing leaders followers, local-density-dependent dynamic field are implemented all together in Most importantly, complete binding mechanism which includes waiting for followers is brought up first time. A counteri...

Path-integral Monte Carlo simulations of liquid helium at negative pressure have been carried out for a temperature range from the critical temperature to below the superfluid transition. We have calculated the temperature dependence of the spinodal line as well as the pressure dependence of the isothermal sound velocity in the region of the spinodal. We discuss the slope of the superfluid tran...

conclusions metacognitive regulation strategies are more considerable prediction than emotional regulation strategies in sd group than in ad group. individuals with ad use alcohol as a means of both cognitive and emotional regulation strategy. patients and methods according to dsm-iv tr criteria, 45 patients with alcohol dependence (ad), 44 patients with substance dependence (sd), and 43 volunt...

conclusions opium was not identified as a risk factor of ischemic stroke. a more extended survey considering further confounding factors is recommended. background one of the supposed risk factors of ischemic stroke is opium addiction, while the researches about its prevalence among patients with stroke are limited. objectives the aim of this study was comparing the prevalence of opium addictio...
