Masses, decay constants and electromagnetic form-factors with twisted boundary conditions

We discuss some of the effects of twisted boundary conditions in finite volume using continuum SU(3) Chiral Perturbation Theory. We point out how broken cubic symmetry affects the definitions of quantities such as form-factors. Using the π+ as an example, we give one loop results for the mass, decay constants and electromagnetic form-factor and illustrate how the relevant Ward identities are satis

Structural topology optimization of multibody systems

Flexible multibody dynamics (FMD) has found many applications in control, analysis and design of mechanical systems. FMD together with the theory of structural optimization can be used for designing multibody systems with bodies which are lighter, but stronger. Topology optimization of static structures is an active research topic in structural mechanics. However, the extension to the dynamic case

Colour reconnection - Models and tests

Recent progress on colour reconnection within the Pythia framework is presented. A new model is introduced, based on the SU(3) structure of QCD and a minimization of the potential string energy. The inclusion of the epsilon structure of SU(3) gives a new baryon production mechanism and makes it possible simultaneously to describe hyperon production at both e+e- and pp colliders. Finally, predictio

ChPT meets lattice : Finite volume and partial quenching for masses, decay constants and VEVs at NNLO

We discuss finite volume effects and partial quenching for Chiral Perturbation Theory in the mesonic sector. The effects are computed in terms of analytical expressions for masses, decay constants and vacuum expectation values (VEVs) to two-loop order. Numerical examples are presented for a number of interesting and relevant cases. All numerical programs are publically available, the prospects of

ATLAS LUCID detector upgrade for LHC Run 2

During the 2009-2013 data taking period (Run I) LUCID was successfully providing information about the luminosity delivered to ATLAS by the LHC. Starting from 2015 (Run II) the LHC machine is expected to provide about twice larger peak instantaneous luminosity and the bunch spacing in the machine is decreased by factor of two (from 50 ns to 25 ns). The original LU-CID design could not cope with th

Bourdieu and the Sociology of Music Education

Pierre Bourdieu has been an extraordinarily influential figure in the sociology of music. For over four decades, his concepts have helped to generate both empirical and theoretical interventions in the field of musical study. His impact on the sociology of music taste, in particular, has been profound, his ideas directly informing our understandings of how musical preferences reflect and reproduce

Gå julaspög

In Skånska årsfester in 1973, I described a few Christmas pranks from the Scanian Recording Collections. The best covered research, "go Christmas ghost" remained untreated. The custom was known since at least the mid-18th century and appeared in most of Scania and a few parishes in Blekinge until the 1930s. Young people made themselves unrecognizable by girls being dressed in outmoded male clothin

TIMESAT : A software package for time-series processing and assessment of vegetation dynamics

Large volumes of data from satellite sensors with high time-resolution exist today, e.g. Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectroradiometer (MODIS), calling for efficient data processing methods. TIMESAT is a free software package for processing satellite time-series data in order to investigate problems related to global change and monitoring of veg

Galectin Inhibitors – Molecular Tools in Biomedical Research and Clinical Implications

Galectins are β-galactoside-binding lectins, which are present in both the intracellular and extracellular environments of cells. During the last two decades, galectins have gained increasing interest as drug targets in various diseases, such as chronic inflammation (fibrosis) and cancer, in which galectins have been shown to play important, and sometimes rate-limiting, roles. Galectins have e.g.

Interactions Between Children and Pediatric Nurses at the Emergency Department : A Swedish Interview Study

Admission to an emergency department can be considered a stressful event for both the child and the family. Due to the nature of traumas, illnesses and fatalities it is a chaotic forum in which good communication between child and staff can be difficult to establish. Purpose: The purpose of the study was to describe nurses' methods when interacting with children aged three to six at a pediatric em
