Satellite–Argo Reconstruction of the Mesoscale-Eddy Sound-Speed Field and Its Effect on Towed-Array Gain: A Differentiable Framework with Bounded Acoustic Feedback

We reconstruct the four-dimensional sound-speed field of mesoscale eddies from satellite sea-level anomaly and sparse Argo profiles with a geostrophically constrained coordinate network, and connect it to array-level acoustics through a differentiable parabolic-equation model and...

Crystallographic Orientation Controls Contact and Spin-Photoresponse in 2D Magnetic Heterostructures

Abstract Two-dimensional ferromagnetic semiconductors such as CrSBr offer exceptional air stability, strong magnetic anisotropy, and rich magneto-optoelectronic coupling, yet inefficient electrical contacts continue to limit carrier injection and spin transport in practical devic...

DynamicFlame Image Generation for Ammonia CombustionMonitoring Using Trend-Encoded Diffusion Models

Abstract Ammonia is a promising green energy carrier, but ammonia combustion, often accompanied by high NOx emissions, poses a great challenge for real-time monitoring. Although flame image-based soft sensors offer a solution for online NOx estimation, the training of this type o...

Pronounced bias-enhanced photocurrent with strong polarization sensitivity in 1T-TiSe2-based photodetectors

We report a 1T-TiSe2-based photodetector with pronounced polarization sensitivity and broadband visible-light photoresponse under low-bias conditions. Using a combined density-functional theory and nonequilibrium Green’s function approach, we calculate the transmission spectra an...

A mechanistic model integrating multi‐source data for operational prediction of rice sheath blight at regional scale

Abstract BACKGROUND Rice sheath blight (RSB) is a destructive disease that causes significant yield losses globally. Accurate regional prediction is critical for sustainable disease management; however, existing models suffer from poor generalizability and limited operational app...

Role of sodium hypophosphite on morphology and corrosion resistance of Ni-P coated Nd-Fe-B

Uniform and dense electroless nickel (EN) was recognized as a promising protective coating for Nd-Fe-B magnets. However, large potential difference between intergranular phase and main phase of Nd-Fe-B made the deposition of EN coating uncontrollable. Sodium hypophosphite was use...
