Charge-exchange neutralization of H3 + with Cs allows preparation of the low-lying Rydberg states of H3. These states are predissociated by the repulsive ground state and may play roles as intermediates in the dissociative recombination of H3 + + e. Translational spectroscopy and measurements of product momentum partitioning in three-body dissociative charge exchange of fast (12 keV) H3 + and D...

This study aims to investigate massive peers, which is an unique characteristics of Massively Multiplayer Online Game (MMOG), and to empirically explore its role on knowledge conversion driven by different types of motivations from an ecological perspective. A number of researchers had investigated learning behaviors in the MMOG virtual environment, however, theoretical justifications of collab...

We study turn-based quantitative multiplayer non zero-sum games played on finite graphs with reachability objectives. In such games, each player aims at reaching his own goal set of states as soon as possible. A previous work on this model showed that Nash equilibria (resp. secure equilibria) are guaranteed to exist in the multiplayer (resp. two-player) case. The existence of secure equilibria ...

Although trust is widely acknowledged as critical to virtual teams, little is known regarding the causes and consequences of trust in leaders of virtual teams. This paper examines the antecedents and consequences of trust in virtual team leaders. Using survey and archival data from a massively multiplayer online game (MMOG), this study’s findings show that trust in the leader is affected by tea...

This paper briefly overviews five studies examining massively multiplayer online role-playing games (MMORPGs). The first study surveyed 540 gamers and showed that the social aspects of the game were the most important factor for many gamers. The second study explored the social interactions of 912 MMORPG players and showed they created strong friendships and emotional relationships. A third stu...

Addiction to online role-playing games is one of the most discussed aspects of recent cyberpsychology, mainly for its potentially negative impact on the social lives of young people. In our study, we focus on some aspects of youth and adolescent addiction to MMORPGs. We investigated connections between players and their game characters and examined if, and in what ways, player relationship to t...

In this article the participants report on a two year research project titled Textuality and Videogames; Interactivity, Narrative Space and Role Play that ran from September 2001, until late 2003 at the Institute of Education, University of London. After presenting an overview of the project, including the methodologies we have adopted, and the questions we have sought to address, we outline tw...

Medium-induced gluon radiation from massless and massive quarks is treated in the same formalism. The dead cone which regulates gluon radiation from massive quarks in the vacuum at small angles, is filled in the medium but constitutes a small fraction of the available phase space. Our study indicates that the energy loss for charmed hadrons at RHIC should be smaller than for light hadrons, but ...

In order to utilize the spin field effect transistor in logic applications, the development of two types of complementary transistors, which play roles of the n- and p-type conventional charge transistors, is an essential prerequisite. In this research, we demonstrate complementary spin transistors consisting of two types of devices, namely parallel and antiparallel spin transistors using InAs ...
