Understanding the relationship between catalytic selectivity and surface structures of heterogeneous catalysts is essential for high-performance catalysis. In this issue Chem, Zhu et al. report a puzzle-solving strategy relying on single-crystal foils Pearson correlation analysis to determine dependence activity principal parameters. Heterogeneous catalysis solid surfaces represents most pervas...

Human land use legacies have significant and long lasting impacts across landscapes. However, investigating the impacts of ancient land use legacies (>400 years) remains problematic due to the difficulty in detecting ancient land uses, especially those beneath dense canopies. The city of Caracol, one of the most important Maya archaeological sites in Belize, was abandoned after the collapse of ...

Forest types of the Wapiti, Doon and Glaisnock catchments, ranked in order of proportion of preferred food species for deer, paralleled a gradient of landform stability. Seral forests and low altitude silver beech forests were preferred deer habitat because they contained the largest proportions of highly preferred species. They often occurred on unstable landforms such as debris cones, colluvi...

The Gibbons conjecture stating the one-dimensional symmetry of certain solutions of semilinear elliptic equations has been proved by several authors. We show how attractivity properties of minimal propagating terraces of one-dimensional parabolic problems can be used in a proof of a version of this result and related statements.
