Self-organized Criticality across 13 Orders of Magnitude in the Solar–Stellar Connection

The Astrophysical Journal
The observed size distributions of solar and stellar flares are found to be consistent with the predictions of the fractal-diffusive self-organized criticality (FD-SOC) model, which predicts power-law slopes with universal constants of α _F  = (9/5) = 1 ...

Identifying Cardiovascular Risk by Nonlinear Heart Rate Dynamics Analysis: Translational Biomarker from Mice to Humans

Brain Sciences
Background: The beat-by-beat fluctuation of heart rate (HR) in its temporal sequence (HR dynamics) provides information on HR regulation by the autonomic nervous system (ANS) and its dysregulation in pathological states.

Research on Slope Early Warning and Displacement Prediction Based on Multifractal Characterization

Fractal and Fractional
The occurrence of landslide hazards significantly induces changes in slope surface displacement. This study conducts an in-depth analysis of the multifractal characteristics and displacement prediction of highway slope surface displacement sequences ...

YOSMR: A Ship Detection Method for Marine Radar Based on Customized Lightweight Convolutional Networks

Journal of Marine Science and Engineering
In scenarios such as nearshore and inland waterways, the ship spots in a marine radar are easily confused with reefs and shorelines, leading to difficulties in ship identification. In such settings, the conventional ARPA method based on fractal detection
