The Mean Across‐Shore Coastal Upwelling Cell in the Southern California Current System

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Equatorward winds off California transport coastal surface waters offshore, which are replaced by deeper onshore flow that upwells. The mean upwelling cell is rarely measured directly because its magnitude is small compared to other variability.

Micro-XCT Imaging and Synthetic Data Generation for Deep Learning-Based Computer Vision of Microstructural Defects

e-Journal of Nondestructive Testing
This study introduces a pipeline that integrates high-resolution micro-X-ray computed tomography (micro-XCT) with synthetic image generation to enable deep learning-based computer vision of microstructural defects. Ammonite fossils were chosen as a case

A Representative Underlying Scale for Spectrally Resolved Energy Dissipation in Surface Breaking Waves

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract In the Duncan‐Phillips framework for breaking wave energy dissipation, the underlying scale at which dissipation occurs is commonly inferred from a measure of the breaking‐wave phase speed, most often taken as the spectrally informed phase speed Cs, $\left({C}_{s}\right),$ the local phase speed at incipient breaking Cb, $\left({C}_{b}\right),$

Perlin noise generation of physiologically realistic cardiac fibrosis

Medical Image Analysis
Fibrosis, a pathological increase in extracellular matrix proteins, is a significant health issue that hinders the function of many organs in the body, in some cases fatally. In the heart, fibrosis impacts on electrical propagation in a complex and poorly predictable fashion, potentially serving as a substrate for dangerous arrhythmias. Individual risk

Financial Time Series Uncertainty: A Review of Probabilistic AI Applications

Journal of Economic Surveys, Volume 40, Issue 2, Page 915-953, April 2026.
ABSTRACT Probabilistic machine learning models offer a distinct advantage over traditional deterministic approaches by quantifying both epistemic uncertainty (stemming from limited data or model knowledge) and aleatoric uncertainty (due to inherent randomness in the data), along with full distributional forecasts.

View-dependent Real-time Rendering of Ocean

工程科学与技术, 2016
:In order to meet strict requirements of real-time and reality of Simulation System, a rendering algorithm of ocean applied to the earth model is proposed. For real-time, ocean mesh grids are classified into near-view part and far-view part.

A Lightweight CNN Based on Axial Depthwise Convolution and Hybrid Attention for Remote Sensing Image Dehazing

Remote Sensing
Hazy weather reduces contrast, narrows the dynamic range, and blurs the details of the remote sensing image. Additionally, color fidelity deteriorates, causing color shifts and image distortion, thereby impairing the utility of remote sensing data.

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

A Space-Time Plume Algorithm to Represent and Compute Dynamic Places

Computers
Contrary to what is represented in geospatial databases, places are dynamic and shaped by events. Point clustering analysis commonly assumes events occur in an empty space and therefore ignores geospatial features where events take place.

A Common Assessment Space for Different Sensor Structures

Sensors, 2019
The study of the evolution process of our visual system indicates the existence of variational spatial arrangement; from densely hexagonal in the fovea to a sparse circular structure in the peripheral retina.
