One of the most interesting scientific challenges nowadays deals with the analysis and the understanding of complex networks’ dynamics and how their processes lead to emergence according to the interactions among their components. In this paper we approach the definition of new methodologies for the visualization and the exploration of the dynamics at play in real dynamic social networks. We pr...

The past few years have seen intensive research efforts carried out in some apparently unrelated areas of dynamic systems – delay-tolerant networks, opportunistic-mobility networks, social networks – obtaining closely related insights. Indeed, the concepts discovered in these investigations can be viewed as parts of the same conceptual universe; and the formal models proposed so far to express ...

This note presents an algorithm that extends a binary choice model to choice among multiple alternatives. Both neoclassical microeconomic theory and Luce choice model are consistent with the proposed algorithm. The algorithm is compatible with several empirical findings (asymmetric dominance and attraction effects) that cannot be explained within standard models.

There is a growing body of research, which suggests that many contemporary urban environments do not support healthy lifestyle choices and are implicated in the obesity pandemic. This paper reviews the evidence from this field in relation to theory, policy and practice, from three different disciplinary perspectives: urban design, geography and public health nutrition. In the UK, our developmen...

The ALMT (aluminium-activated malate transporter) family comprises a functionally diverse but structurally similar group of ion channels. They are found ubiquitously in plant species, expressed throughout different tissues, and located in either the plasma membrane or tonoplast. The first family member identified was TaALMT1, discovered in wheat root tips, which was found to be involved in alum...

Elicited narrative studies have shown that the underlying pragmatic factor of empathy is relatively preserved in aphasic speakers of Japanese and English (7 Japanese and 14 English-speaking aphasics of varied diagnostic types). Occasional "reversal errors" can be explained in terms of a conflict between the normal encoding of the empathic characteristics of an event and the syntactic limitation...

How to guide players towards a more interesting experience without taking away player agency is a key challenge in game design. In this paper, we propose our approach for guiding players’ spatial navigation in 3D adventure games. Based on close analysis of popular adventure games, we propose a set of five 3D structural composition patterns to guide players through level design. To evaluate thei...

Among the most diicult challenges in providing real-time multimedia servicess9] to applications are coping with heterogeneity of end nodes (consisting of various input and output devices) and heterogeneity of media Quality of Service (QoS) requirementss11]. We discuss several architectural choices possible in logical multiplexing, accommodating QoS dynamics, and functional divisions between sen...
