Solar Storm Type Classification Using Probabilistic Neural Network compared with the Self-Organizing Map [PDF]

, 2012
One of the task of the LAPAN is making observation and forecasting of solar storms disturbance. This disturbances can affect the earths electromagnetic field that disrupt the electronic and navigational equipment on earth.

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 ...

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 ...

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

Acta Ophthalmologica, Volume 104, Issue 4, Page 410-422, June 2026.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Advancing Brain and Body Vascular Imaging in Bipolar Disorder: A Report From the International Society for Bipolar Disorders Vascular Task Force

Bipolar Disorders, Volume 28, Issue 4, June 2026.
ABSTRACT Objectives The heart–brain nexus is increasingly recognized as important for human health. Nonetheless, integration of this perspective in research and treatment remains limited in psychiatry, particularly in bipolar disorder (BD). Multisystem vascular imaging may help elucidate mechanisms linking heart and brain health in BD.

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.

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.

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.

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

Von Lindener's sunspot data: sunspot group number and individual sunspot number

, 2023
Hayakawa et al. (2023) derived sunspot group number and individual sunspot number from von Liindener's records. These data have been extracted from von Lindener's manuscript (Akc.1985/15) in the Library of Wrocław University and Bode (1819).
