Morphological anisotropy of shear failure surfaces of granite rock bridges
Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesRock bridges are critical for the stability of rock masses and often experience shear failure under natural conditions. As a manifestation of the failure mechanisms of rock bridges, we investigate the morphology of failure surfaces created by direct ...

People and Nature, EarlyView.Abstract The societal and biophysical permeability across human‐demarcated jurisdictions within watersheds necessitates collaboration among administrative regions. The effectiveness of such collaboration is partly determined by the degree to which institutional arrangements align with underlying social and ecological interdependencies, a concept ...

Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesComparison is a crucial stage of site-level selection process. This study integrates the geographic information system (GIS) techniques and analyses the stability of predictions based on five machine learning models to identify key indices for site ...

Applied SciencesLandslide risk assessment (LRA) is an important basis for disaster risk management. The widespread phenomenon of landslide spatial aggregation brings uncertainty to landslide hazard assessment (LHA) in LRA studies, but it is often overlooked.

A protein coevolution method uncovers critical features of the Hepatitis C Virus fusion mechanism. [PDF]
PLoS Pathogens, 2018 Amino-acid coevolution can be referred to mutational compensatory patterns preserving the function of a protein. Viral envelope glycoproteins, which mediate entry of enveloped viruses into their host cells, are shaped by coevolution signals that confer ...

PLANTS, PEOPLE, PLANET, EarlyView.The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Fluctuations and correlations in an individual-based model of biological coevolution
, 2004 We extend our study of a simple model of biological coevolution to its statistical properties. Staring with a complete description in terms of a master equation, we provide its relation to the deterministic evolution equations used in previous ...

PLANTS, PEOPLE, PLANET, EarlyView.This study examines how the fruits of non‐photosynthetic forest plants in the Monotropoideae (Ericaceae) have evolved into the diversity observed today. By analyzing four Asian species, we identified a shift from dry, dehiscent fruits that release seeds into the air to fleshy, berry‐like fruits adapted for animal dispersal.
