The Playing Session: Enhanced Playability for Mobile Gamers in Massive Metaverses
Full text linkInternet ubiquity and the success of mobile gaming devices are increasing the interest in wireless access to virtual environments. Mainly due to the mobility factor and wireless medium features, traditional gaming architectures are not enough to guarantee good levels of playability and fairness to mobile gamers. We suggest a new mechanism, called playing session, capable of controlling communications between mobile devices and the game infrastructure. In case of network failures, a mimicking mechanism is in charge of playing, until the communication channel is restored. The goal is to reproduce, with an adequate level of mimesis, the user behavior. According to this approach, it will be possible to enhance the overall playability of Internet games without requiring any modification to the existing communication infrastructure
A Hydrogel Based on a polyaspartamide: Characterization and Evaluation of In-vivo Biocompatibility and Drug release in the Rat.
No full textAbstract
This paper deals with the characterization of a new microparticulate hydrogel obtained by gamma irradiation of α,β-poly[N-(2-hydroxyethyl)-dl-aspartamide] (PHEA).
When enzymatic digestion of PHEA hydrogel was evaluated using various concentrations of pepsin and α-chymotrypsin no degradation occurred within 24 h. In-vivo studies showed that this new material is biocompatible after oral administration to rats. PHEA hydrogel was also studied as a system for delivery of diflunisal, an anti-inflammatory drug. In-vitro release studies in simulated gastrointestinal juice (pH 1 or 6.8) showed that most of the drug was released at pH 6.8. In-vivo studies indicated that diflunisal-loaded PHEA microparticles significantly improved the gastric tolerance and oral bioavailability of the drug in comparison with free diflunisal.
These results suggest the potential application of PHEA hydrogel as a new delivery system for the oral administration of anti-inflammatory drugs.</jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
A RIO-like Technique for Interactivity Loss Avoidance in Fast-Paced Multiplayer Online Games
No full textThe astonishing increase in the spread of the Internet has given rise to a globally connected community proficient at deploying online games for a large number of participants geographically located very far from each other. However, online games are characterized by more stringent requirements than traditional distributed applications deployed over the Internet can fulfill. Indeed, one of the key factors in determining the success of an online game is its ability to rapidly deliver events to the various game servers that maintain the state of the game over the network. We have already demonstrated [Palazzi et al. 2004] that in this context adapting RED (random early detection) techniques, borrowed from queuing management, can improve the global responsiveness of a game. However, this solution may not be sufficient for a specific class of online games. We deem that fast-paced multiplayer online games (such as shoot 'em ups, for example) in which participants have to behave frenetically, must guarantee a very high degree of interactivity, even at the cost of partially sacrificing the consistency of the game state. In this case having only a partially consistent view of the game state will not affect a player's amusement as much as delaying action-processing activity will. Hence we explore the possibility of applying a RIO-based (RED with in and out) algorithm to manage game delivery to the various game servers, in order to improve the degree of interactivity for fast-paced online games. Preliminary experimental results confirm the viability of our approach
