Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

open access: yesFood Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Craniofacial Resection for Advanced Cutaneous Squamous Cell Carcinoma: Results From the 2nd International Collaborative Case‐Series

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Robust outcome data for anterior skull base cutaneous squamous cell carcinoma (cSCC) are limited, particularly as emerging therapies reshape management. We evaluated survival and prognostic factors following craniofacial resection. Methods Retrospective multi‐institutional case‐series (1995–2015) of patients who underwent skull base

Where Projects Fail: Geospatial Evidence of Delays and Cancellations in Chinese Development Finance

open access: yesJournal of International Development, EarlyView.
ABSTRACT Delays and cancellations can severely undermine the effectiveness of development finance. Yet, little systematic evidence exists on where and why these disruptions occur within the rapidly expanding portfolio of Chinese‐financed development projects in Africa.
