The Advective Flux Transport Model: Improving the Far Side with Active Regions Observed by STEREO 304 Å

The Astrophysical Journal
Observations of the Sun’s photospheric magnetic field are often confined to the Sun–Earth line. Surface flux transport (SFT) models, such as the Advective Flux Transport (AFT) model, simulate the evolution of the photospheric magnetic field to produce ...

Human‐Interpretable SEP Event Prediction Using White‐Box Explainable AI

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Solar energetic particle (SEP) events pose radiation risks to astronauts and space systems, making their prediction essential. Although various prediction models have been developed, most machine learning (ML)‐based models lack interpretability; that is, it is difficult to explain the reasons behind individual predictions.

FUNCTIONAL SUNSPOT EQUILIBRIA [PDF]

Consider a one step forward looking model where agents believe that the equilibrium values of the state variable are determined by a function whose domain is the current value of the state variable and whose range is the value for the subsequent period ...

Superposed Epoch Analysis of Extreme Geomagnetic Disturbances at Auroral Zone Latitudes Over a Solar Cycle

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Intense and rapidly changing electrical currents in near‐Earth space produce geomagnetic disturbances (GMDs) with large magnetic field rates of change (dB/dt) and in turn large geomagnetically induced currents (GICs) in nearby power lines and pipelines. This study builds on the work of Engebretson, Yang, et al.

Analysis of BMR Tilt from AutoTAB Catalog: Hinting toward the Thin Flux Tube Model?

The Astrophysical Journal
One of the intriguing mechanisms of the Sun is the formation of bipolar magnetic regions (BMRs) in the solar convection zone (CZ), which are observed as regions of concentrated magnetic fields of opposite polarity on the photosphere.

Dual 1550‐nm Erbium Glass Fiber and 1927‐nm Thulium Fiber Non‐ablative Fractional Laser System Treatment in Patients With Skin of Color: A Review of Clinical Studies and Unmet Needs

Lasers in Surgery and Medicine, Volume 58, Issue 3, Page 169-179, March 2026.
ABSTRACT Objectives To review the efficacy and safety of the dual 1550‐nm erbium glass fiber and 1927‐nm thulium fiber non‐ablative fractional laser system in patients with skin of color (ie, Fitzpatrick skin types [FSTs] III–VI). Materials and Methods Efficacy, safety, and histologic outcomes were reviewed from 15 clinical studies examining the use of

Novel Combined Approach for Vision‐Preserving Iridociliary Tumour Excision in a Small‐Breed Dog: Contralateral Iris Excision With En‐Bloc Scleral Resection

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• A 2.8 mm corneal paracentesis positioned opposite to the tumour location enabled fine iris scissors insertion for precise excision of tumour‐bearing iris tissue under miotic guidance with pilocarpine 2%. • A fornix‐based conjunctival peritomy 5 mm from the limbus and stepped scleral flap approach allowed circumferential deep scleral incision with 2–3

Neuroinflammation‐Associated Optic Structural–Functional Degeneration in Early Diabetic Optic Neuropathy

Journal of Diabetes, Volume 18, Issue 3, March 2026.
OCT imaging assessments and visual tests, which were validated by pyroptosis of retinal ganglion cells (RGC) and upregulation of NLRP3 and GSDMD expression, established an early structure‐function‐pathology diabetic optic neuropathy (DON) model in high glucose & obesity mice. Early retinal nerve fiber layer (RNFL)/total retinal thickness (TRT) thinning

Personalized Models of Biological Barriers and Their Diseases: Recent Progress with Organs‐On‐Chips

Advanced Biology, Volume 10, Issue 2, February 2026.
Buck and Bugter et al. explore the architectural diversity and physiological functions of human barrier systems and reveal how organ‐on‐chip platforms, particularly those integrating patient‐derived cells, are advancing barrier disease modeling. They highlight how emerging biological and technological advances can be used to bridge the gap between ...

Addressing Known Challenges in Solar Flare Forecasting I: Limb‐Flare Prediction With a 4π Full‐Heliosphere Framework

Space Weather, Volume 24, Issue 2, February 2026.
Abstract A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming, we develop a “4π $4{\uppi }$” full‐heliosphere event forecasting framework and evaluate its statistical classification ability against this specific challenge.
