    Outpatient clinics have been severely restricted during COVID-19; the specialties face a tremendous challenge in service provision going forward. Attendance has been low in many centres despite implementation of COVID-19-related safety precautions.1 This study aimed to ...

    The chemical composition of the solid grains from comet Halley can be inferred from impact-ionization time-of-flight mass spectrometry. Halley's dust in the vicinity of the VEGA-1 spacecraft is a mixture of a refractory organic component and unequilibrated silicates, bu...

    The electrons found in Dirac materials are notorious for being difficult to manipulate due to the Klein phenomenon and absence of backscattering. Here we investigate how spatial modulations of the Fermi velocity in two-dimensional Dirac materials can give rise to locali...

  • It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as dispersers. See...

    Whole and dissected hops have been dried under controlled conditions and their rates of loss of moisture followed. It is shown that the bracts* dry much more rapidly than do the strigs, both when dried on the whole hop and when the two components are dissected out and d...

    DURING studies of Compton and Rayleigh scattering from suspensions and slurries, we observed that the X-ray intensities showed a markedly different dependence on the size of the grains of the more strongly absorbing component of the material. We investigated these effec...

    We study the average-case running-time of single-source shortest-path (SSSP) algorithms assuming arbitrary directed graphs with n nodes, m edges, and independent random edge weights uniformly distributed in [0,1]. We give the first label-setting and label-correcting alg...

    a b s t r a c t Several multi-year biodiversity experiments have shown positive species richness-productivity rela- tionships which strengthen over time, but the mechanisms which control productivity are not well understood. We used experimental grasslands (Jena Experim...
