GeSn‐on‐Si Avalanche Photodiodes with High Responsivity and Low Dark Current

Advanced Electronic Materials, Volume 11, Issue 21, December 17, 2025.
GeSn‐on‐Si avalanche photodiodes with up to 1.9% Sn are fabricated and characterized. They exhibit exceptionally low dark currents and achieve a record‐high responsivity of 14.7 A W−1 at 1550 nm. The image highlights the double‐mesa design and spectral performance, demonstrating the potential of complementary metal‐oxide‐semiconductor (CMOS)‐compatible

Surface Runoff and Sediment Yield Modelling Under No‐Till: Chiselling and Crop Management Effects

Hydrological Processes, Volume 39, Issue 12, December 2025.
The study demonstrates the applicability of the LISEM model in simulating erosion processes on agricultural hillslopes under no‐till farming. Modelling at the hillslope scale allows for a more precise description of the initial stages of runoff formation and propagation, which is often difficult to observe at the catchment scale.

Inverse Uncertainty Quantification using the Modular Bayesian Approach based on Gaussian Process, Part 2: Application to TRACE

, 2018
Inverse Uncertainty Quantification (UQ) is a process to quantify the uncertainties in random input parameters while achieving consistency between code simulations and physical observations. In this paper, we performed inverse UQ using an improved modular

Efficient and Regionally Transferable Snow Water Equivalent Estimation Using a Long Short‐Term Memory Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Snow reanalyses that combine process based models and remote sensing observations of snow provide estimates of seasonal snow water equivalent (SWE) evolution that surpass the accuracies of traditional modeling approaches. However, snow reanalyses are only available over smaller subregions and sometimes use computationally expensive modeling ...

Deep Learning‐Based MultiSource Satellite Data Fusion and Downscaling for Tropical Cyclone Wind Fields

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract High‐resolution observations of ocean surface wind (OSW) are crucial for analyzing and forecasting tropical cyclones; however, current data are insufficient. While data sets such as the Cross‐Calibrated Multiplatform (CCMP) and ERA5 provide gap‐free wind fields, their 25 km resolution and tendency to underestimate cyclone wind speeds limit ...

An extremely high velocity molecular jet surrounded by an ionized cavity in the protostellar source Serpens SMM1

, 2016
We report ALMA observations of a one-sided, high-velocity ($\sim$80 km s$^{-1}$) CO($J = 2 \rightarrow 1$) jet powered by the intermediate-mass protostellar source Serpens SMM1-a. The highly collimated molecular jet is flanked at the base by a wide-angle

A Conceptual Framework for Erosion of Unsaturated Cohesive Soil

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Accurately predicting soil erosion remains difficult owing to variability in the factors that drive the interaction of unsaturated flow and soil deformation. For example, seasonal changes in soil moisture affect infiltration, swelling, and soil stiffness, all factors that interact and may affect soil erosion through changes in matric suction ...

Analysing the Impact of 3D-Printed Perforated Panels and Polyurethane Foam on Sound Absorption Coefficients

Modelling
Effective sound absorption is crucial in environments like schools and hospitals. This study evaluates open-pore polyurethane foam and perforated onyx panels, which attenuate noise via distinct mechanisms: porous materials convert sound energy to heat ...
