Optimization on the Polarization and Waveform of Radar for Better Target Detection Performance under Rainy Condition

open access: yesRemote Sensing
Under rainy conditions, atmospheric settling particles have significant depolarization effects on radar waves and thus affect the target detection performance.

Covert Optical Fingerprints Within Overt Structural Colors via Cascaded Cavity Resonances

open access: yesAdvanced Science, EarlyView.
Cascaded photonic–plasmonic cavities combine vivid structural colors with hidden stochastic optical fingerprints in a single monolithic platform. Layered cavities control the overt appearance, while disordered nanogap resonances generate covert scattering with limited mutual influence.

Architected Load Paths Enable Stiffening and Motion Programming in Soft Pneumatic Actuators

open access: yesAdvanced Science, EarlyView.
A single MARS template introduces an architected reinforcement strategy for programmable soft pneumatic actuators through internal structural organization and selective beam removal. This monolithic architecture enables deformation reconfiguration from continuous bending to joint‐like articulation and torsional motion, allowing one compliant platform ...

Rainfall Forecasting Using an Adaptive Neuro-Fuzzy Inference System with a Grid Partitioning Approach to Mitigating Flood Disasters [PDF]

open access: yes
Hydrometeorological disasters are one of the disasters that often occur in big cities like Semarang. Hydrometeorological disasters that often occur are floods caused by high-intensity rainfall in the area.

Perovskite CsPbI3 Nanocrystal and Nanowire Incorporated G‐C3N4 Nanosheets for CO2 Reduction and NO Removal

open access: yesAdvanced Science, EarlyView.
CsPbI3 nanostructures integrated with g‐C3N4 formed S‐scheme heterojunctions enabling efficient photocatalytic CO2 reduction and NO abatement. The g‐C3N4/CsPbI3 nanowires achieved a CO production rate of 4.6 µmol g−1 h−1, while nanocrystal composites delivered 69.5% NO removal with only 5.0% NO2 selectivity, driven by highly energetic charge carriers ...

Trends in Rainfall and Economic Growth in Africa: A Neglected Cause of the Growth Tragedy [PDF]

open access: yes
We examine the role of trends in rainfall in the poor growth performance of sub-Saharan African nations relative to other developing countries. To do so we use a new crosscountry panel climatic data set in an empirical economic growth framework.

Climate Change is Rewriting the Hydroclimatic Operating Envelope of Mines

open access: yesAdvanced Science, EarlyView.
Climate change is shown to shift the hydroclimatic operating envelope of mines: 16.2% of represented mine locations have already changed Köppen subtype, rising to 42.5% by late century under SSP5‐8.5. Divergent water trajectories are filtered through geology, infrastructure and lifecycle stage, indicating that adaptation requires monitored, scenario ...

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

open access: yesAdvanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Multi-source fusion for high-precision quantitative precipitation estimation in the Pearl River Basin

open access: yesJournal of Hydrology: Regional Studies
Study region: The Pearl River Basin in South China. Study focus: Infrared-based satellite rainfall monitoring faces challenges due to limitations in cloud-top observations, as geostationary meteorological satellites cannot directly measure sub-cloud ...
