Late-time tails of self-gravitating skyrmions

We consider the long-time behaviour of spherically symmetric solutions in the Einstein-Skyrme model. Using nonlinear perturbation analysis we obtain the leading order estimation of the tail in the topologically trivial sector (B = 0) of the model. We show that solutions starting from small compactly supported initial data decay as 1/t^4 at future timelike infinity and as 1/u^2 at future null infinity. We also verified that long-time behaviour for the tail in Einstein-Skyrme model is exactly the same as it was obtained for wave maps.Comment: 7pp; revised version - title changed, sects. 2 and 3 replaced by the new version of sect. 2 with new figure added, section on numerics slightly modified, references updated, accepted for publication in Acta Phys.

Effect of health worry on processing of health information, behavioral intentions, and behavior

Although correlational studies show a relationship between worry about health concerns and higher rates of self-protective behavior, there has been no experimental research supporting the relationship and little research on the mechanisms by which worry might lead to health behaviors. This study experimentally induced a state of worry about influenza in undergraduate college students (N = 165), and examined their intentions to get a flu shot, systematic processing of a message about influenza, and vaccination behavior. The study had four main findings. First, the worry induction was successful in inducing worry about influenza. Second, participants in the experimental (worry) group reported significantly greater intentions to get a flu shot when compared with the intentions of the control group. Group differences in vaccination behavior were in the predicted direction, but were not significant. Third, participants in the experimental group had significantly higher rates of systematic processing of the flu message. However, systematic processing did not mediate the relationship between worry about the flu and intention to get a flu shot. The results support the role of emotion in health behavior decisions and introduce an effective experimental technique for inducing worry about a health condition

Majorana neutrino mass matrix with CP symmetry breaking

From the new existing data with not vanishing theta13 mixing angle we determine the possible shape of the Majorana neutrino mass matrix. We assume that CP symmetry is broken and all Dirac and Majorana phases are taken into account. Two possible approaches "bottom-up" and "top down" are presented. The problem of unphysical phases is examined in detail.Comment: 6 pages, 2 figures, presented at the XXXV International Conference of Theoretical Physics "Matter to the Deepest 2011", Ustron, Poland, September 12-18, 201

Minimally Unbalanced Quivers

We develop a classification of \emph{minimally unbalanced} $3d~\mathcal{N}=4$ quiver gauge theories. These gauge theories are important because the isometry group $G$ of their Coulomb branch contains a single factor, which is either a classical or an exceptional Lie group. Concurrently, this provides a classification of hyperk\"ahler cones with isometry group $G$ which are obtainable by Coulomb branch constructions. HyperK\"ahler cones such as Coulomb branches of $3d~\mathcal{N}=4$ quivers are indispensable tools for describing Higgs branches of different theories in various dimensions. In particular, they are used to describe Higgs branches of $5d~\mathcal{N}=1$ SQCD with gauge group $SU(N_c)$ and $6d~\mathcal N = (1,0)$ SQCD with gauge group $Sp(N_c)$ at the respective UV fixed points.Comment: 59 page

An inventory of recent innovations in fruit and fruit products

The goals of this study were to make an inventory of recent and ongoing fruit and fruit product innovations, to assess what novelty or improvement they offer, and whether consumers could identify and/or recognise them. Researchers from 11 European countries submitted 386 examples of fruit and fruit product innovations. The list of innovations obtained has been coded, categorised, sorted, and reduced in subsequent stages. First, the examples received were categorised according to the Oslo Manual definitions. Second, product and marketing innovations were selected, as they are the only ones that were likely to be recognised by consumers. Next, analysis revealed that the novelties these innovations offered related to Convenience, Health, Differentiation, Target Group, Information, Sensory Characteristics, In Home and/or Out of Home Quality. Some innovations offered only one novel aspect, whereas others offered multiple aspects. Interrelationships between novel aspects are discussed for those innovations that offered a combination of aspects
