Experimental study on I/II/III mixed mode fracture characteristics of a combined rock mass under creep loading

Scientific Reports
I/II/III mixed mode fractures of intersecting joint fissures often occur in natural rock masses, and jointed rock masses are prone to rockbursts in deep underground engineering when subjected to long-term crustal stresses.

Electric Field‐Induced Hole‐ and Electron‐Type Flat Bands in Twisted Double Bilayer Graphene

Advanced Electronic Materials, EarlyView.
The electronic structure of twisted double bilayer graphene is visualized using angle‐resolved photoemission spectroscopy with micrometer spatial resolution at twists of 3.1∘$^\circ$ and 6.0∘$^\circ$ as a function of gate voltage. Tunable hybridization effects and flat band formation occurs between valence and conduction band states due to a finite ...

Optimizing Urban Traffic Management: Investigating the Impact of Probe Vehicle Road Coverage, Penetration Rates, and Speed Data Quality in Macroscopic Fundamental Diagram Estimation

Journal of Advanced Transportation
Probe vehicles and loop detectors collect traffic data for empirical MFD estimation. The accuracy of MFD estimation is contingent upon the percentage of road network links covered (road coverage) and the extent of information (penetration rate) from each

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Longitudinal splitting and grouting in deep buried rock layers based on the coupling effect between slurry and rock

Scientific Reports
The coupling effect between slurry and a fractured rock layer controls the width of the fracturing channel and the grouting pressure. This effect is attenuated as the slurry diffusion front spreads from the grouting hole.
