Musical control gestures in mobile handheld devices: Design guidelines informed by daily user experience

Mobile handheld devices, such as smartphones and tablets, have become some of the most prominent ubiquitous terminals within the information and communication technology landscape. Their transformative power within the digital music domain changed the music ecosystem from production to distribution and consumption. Of interest here is the ever-expanding number of mobile music applications. Despite their growing popularity, their design in terms of interaction perception and control is highly arbitrary. It remains poorly addressed in related literature and lacks a clear, systematized approach. In this context, our paper aims to provide the first steps towards defining guidelines for optimal sonic interaction design practices in mobile music applications. Our design approach is informed by user data in appropriating mobile handheld devices. We conducted an experiment to learn links between control gestures and musical parameters, such as pitch, duration, and amplitude. A twofold action—reflection protocol and tool-set for evaluating the aforementioned links—are also proposed. The results collected from the experiment show statistically significant trends in pitch and duration control gesture mappings. On the other hand, amplitude appears to elicit a more diverse mapping approach, showing no definitive trend in this experiment.info:eu-repo/semantics/publishedVersio

Opinion and community formation in coevolving networks

In human societies opinion formation is mediated by social interactions, consequently taking place on a network of relationships and at the same time influencing the structure of the network and its evolution. To investigate this coevolution of opinions and social interaction structure we develop a dynamic agent-based network model, by taking into account short range interactions like discussions between individuals, long range interactions like a sense for overall mood modulated by the attitudes of individuals, and external field corresponding to outside influence. Moreover, individual biases can be naturally taken into account. In addition the model includes the opinion dependent link-rewiring scheme to describe network topology coevolution with a slower time scale than that of the opinion formation. With this model comprehensive numerical simulations and mean field calculations have been carried out and they show the importance of the separation between fast and slow time scales resulting in the network to organize as well-connected small communities of agents with the same opinion.Comment: 10 pages, 5 figures.

"Cloud computation" na forma de serviços WEB para um banco de dados federativo STING_RDB.

O STING é um produto - plataforma com interface para fácil análise de estruturas macromoleculares (proteicas e de DNA) baseado em um conjunto de pre-calculados descritores de estrutura 3-dimensional destas moléculas. Os descritores encontram se em um banco relacional de dados, mantido automaticamente, atualizado em periodos regulares, acompanhando o crescimento de informações disponibilizadas publicamente pelos principais provedores e repositores mundiais, tais como: PDB, UNIPROT, HSSP, PROSITE, PROTHERM etc. Nossa proposta visa reformulação da maneira do trabalho e da desenvolvimento das principais ferramentas oferrecidas para a comunidade cientifica: queremos fazer o STING um "(bio)logic programable layer" em cima da "processing network layer" (composta por CENABIDs, e outros cluster e núcleos de alto processamento). A maior demanda no campo da Bioinformática é por SOFTWARE de qualidade e não como muitos acreditam, por numero elevado de CPUs. As condições de nosso trabalho permitem montar um sistema genuinamente distribuído, fazendo uso mais racional dos hardwares já adquiridos. Isso possibilitara também que outros interessantes pacotes (a maioria ainda protótipos de uma ideia promissora) de bioinformática, desenvolvidos nos mais diversos rincões de pesquisas possam ser tirados do seu ostracismo e trazidos para a integração. Logo, a racionalização acabara abrangendo também os aplicativos. O STING pode ser esse componente aglutinador, possivelmente tornando-se um padrão de componentização: uma verdadeira plataforma para desenvolvimento de aplicações distribuída em bioinformática. O STING se tornara uma API (Application Programming Interface) capaz de manipular todos os parâmetros presentes no seu RDB. As WEB-APIs dos diversos centros brasileiros e dos outros paises, estarão "virtualmente" integradas nos middlewares, e diferentes aplicações poderão ser montadas por diferentes usuários conforme os diferentes interesses

Failure regime in (1+1) dimensions in fibrous materials

In this paper, we introduce a model for fracture in fibrous materials that takes into account the rupture height of the fibers, in contrast with previous models. Thus, we obtain the profile of the fracture and calculate its roughness, defined as the variance around the mean height. We investigate the relationship between the fracture roughness and the fracture toughness.Comment: 4 pages, 4 figures.eps, Revte

A Minimal, Unstrained S-Allyl Handle for Pre-Targeting Diels-Alder Bioorthogonal Labeling in Live Cells

The unstrained S-allyl cysteine amino acid was site-specifically installed on apoptosis protein biomarkers and was further used as a chemical handle and ligation partner for 1,2,4,5-tetrazines by means of an inverse-electron-demand Diels-Alder reaction. We demonstrate the utility of this minimal handle for the efficient labeling of apoptotic cells using a fluorogenic tetrazine dye in a pre-targeting approach. The small size, easy chemical installation, and selective reactivity of the S-allyl handle towards tetrazines should be readily extendable to other proteins and biomolecules, which could facilitate their labeling within live cells.China Scholarship Council, FCT Portugal, European Union (Marie-Sklodowska Curie ITN Protein Conjugates; Marie-Sklodowska Curie IEF), MINECO (CTQ2015-70524-R and RYC-2013-14706), Engineering and Physical Sciences Research Council, BiFi (Memento cluster), Royal Society, European Research Counci
