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...

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...

Attempts to influence the development of land systems are often based on detailed scenarios that constrain relevant factors, describe a range of divergent but plausible futures and identify potential pathways to visions of desirable conditions. However, a number of assu...

This work was supported by the grants by the Region Aquitaine (to E.M.B) and PEPS (Initial Support for Exploratory Projects to E.M.B) and National Agency for Research (Grant ANR-14-CE19-0006-01 to E.M.B). Plasmodesmata are remarkable cellular machines responsible for th...

Recent research suggests that safer student alcohol consumption might be assisted by understanding how social occasions are managed by non-drinkers. In-depth, semi-structured interviews with five 19-22 year old non-drinking English undergraduates were subjected to inter...

From a national cohort of 8,806 children examined at ages seven, 11 and 16 years (National Child Development Study), data on asthma or wheezing illness (AW) were analyzed to describe its natural history in childhood and its risk factors. Factors found to predict the sub...
