Spatial Lock‐In and Reclamation Delay in Coal‐Subsidence Landscapes: Land Degradation Under Passive Water‐Retention Strategies

Land Degradation &Development, EarlyView.
ABSTRACT In coal‐grain composite regions, intensive underground coal extraction causes large‐scale surface subsidence; under shallow groundwater conditions, these subsided landscapes rapidly transform former croplands into persistent open water bodies, creating long‐term inundated landscapes. Passive water‐retention strategies in these areas often rely

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

Limnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Optimizing stereo‐baited remote underwater video sampling efficiency in turbid waters through horizontal field of view adjustments

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate length data underpin many ecological and physiological analyses, from assessing population size structure to parameterizing biomass and bioenergetic models. Stereo‐baited remote underwater video systems (stereo‐BRUVs) provide a non‐intrusive means of collecting these data in situ, supporting management and conservation of motile ...

Frontiers of Bright CEP‐Stable Broadband Infrared Sources

Laser &Photonics Reviews, EarlyView.
Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage

Laser &Photonics Reviews, EarlyView.
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.
