A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Multi‐Decadal Trends in the Low Latitude foF2 Driven by Secular Magnetic Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Long‐term ionospheric trends have been widely studied, but their origin and magnitude remain subjects of debate. This study quantifies the linear trend in the F2‐region critical frequency (foF2) and its local time dependence using observations from eight low‐latitude ionosonde stations.

Decellularized Aged Bruch's Membrane Confers Unique Biochemical Cues to Retinal Pigment Epithelium for In Vitro Modeling of Age‐Related Macular Degeneration

Aging Cell, Volume 25, Issue 5, May 2026.
A Bruchs membrane (BrM) mimic based on aged decellularized BrM was developed and differentially expressed proteins in aged dECM‐BrM that may provide specific biochemical cues fundamental to model AMD in vitro were identified. RPE culture on aged dECM‐BrM developed certain AMD‐like features including reduced TEER and expression of drusen components ...

Choroidal vascular hyperpermeability patterns in central serous chorioretinopathy correlate with microperimetry: CERTAIN study report 4

Acta Ophthalmologica, Volume 104, Issue 3, Page 288-295, May 2026.
Abstract Purpose This report evaluates the association of three distinct leakage patterns of choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA), previously correlated with disease chronicity, with retinal sensitivity measured by microperimetry in central serous chorioretinopathy (CSC): unifocal indistinct signs of ...
