Strain localisation plays a key role in the deformation of granular materials. Such localisation involves bands of just a few grains wide, which dominate the material's macroscopic response. This grain-scale phenomenon presents challenges for continuum modelling, which is the rationale behind models that explicitly take micro-scales into account. These in turn require micro-scale experimental anal

Electron–ion coincidence measurements with energy-resolved electrons are a powerful tool in studies of molecular fragmentation processes, since fragmentation from a specific doorway state can be monitored while the remaining reactions are discriminated. Presently, we have applied this technique in measurements of coincidence spectra of the CD4 and SF6 molecules after valence and core electron exci

Popular Abstract in Swedish Västeuropeiska stater har blivit alltmer mångkulturella. Migrationsflöden från fattigare delar av välden har bidragit till att länder som tidigare uppfattade sig själva som homogena, uppvisar en allt högre grad av kulturella, etniska och religiösa olikheter. Förespråkare för mångkulturalism har argumenterat att ett sätt att hantera gruppers olikheter är att tolerera derWestern European states are faced by societies with increasing ethnic, cultural and religious diversity as a result of migration flows. Advocates of multiculturalism have tried to address these potential challenges by advocating the accommodation of minorities within the recipient society. This study argues that the normative and practical measures suggested by multiculturalists tend to be de-cont

PURPOSE: To identify and develop a conceptual map of prioritized areas and to determine their relative importance for outcome measurement in clinical Parkinson's disease (PD) trials, from the perspectives of health care professionals and people with PD. METHOD: We used concept mapping, a qualitative/quantitative method consisting of three steps: item generation through focus groups (n = 27; 12 peo

The present study introduces sparse modeling for the estimation of propagation patterns in intracardiac atrial fibrillation (AF) signals. The estimation is based on the partial directed coherence (PDC) function, derived from fitting a multivariate autoregressive model to the observed signals. A sparse optimization method is proposed for estimation of the model parameters, namely, the adaptive grou

Background: Computed tomography angiography (CTA) of intracranial arteries has high demands on image quality. Important parameters influencing vessel enhancement are injection rate, concentration of contrast media and tube voltage. Purpose: To evaluate the impact of an increase of contrast media concentration from 300 to 400 mg iodine/mL (mgI/mL) and the effect of a decrease of tube voltage from

Four recombinant Saccharomyces cerevisiae strains with enhanced xylose growth (TMB3400, C1, C5 and BH42) were compared with two control strains (TMB3399, TMB3001) through genome-wide transcription analysis in order to identify novel targets for inverse metabolic engineering. A subset of 13 genes with changed expression levels in all improved strains was selected for further analysis. Thirteen vali
