Comparing results of real-scale time MHD modeling with observational data for first flare M 1.9 in AR 10365

Open Astronomy, 2022
As shown in the first results of MHD simulations in the real scale of time, above the active region (AR) 10365, during the first flare M 1.9 (05/26/2003 05:34) at a height of 16–18 mm (lower corona), a singular line of magnetic field appears.

MMLTC: A Novel Tolerance‐Based Clustering Framework for Multimodal Sentiment and Harmful Meme Classification in Multilingual Settings

Computational Intelligence, Volume 42, Issue 2, April 2026.
ABSTRACT This work introduces a novel Tolerance‐Based Clustering Framework (MMLTC) framework for affective analytics of multimodal/multilingual content in social media. A key feature of the MMLTC framework is its ability to overcome limitations of prior tolerance‐based classifiers through the construction of label specific pure tolerance classes ...

Microwave diagnostics of flare plasma by the direct fitting method based on data from the Siberian Radioheliograph

Solar-Terrestrial Physics
In this paper, we analyze images and the frequency spectrum of microwave emission in the maximum of brightness distribution in the January 20, 2022 and July 16, 2023 flares recorded by the Siberian Radioheliograph in the 3–6 GHz and 6–12 GHz ranges.

PHASE ERROR MEASUREMENT AND CORRECTION IN 8-CM RADIOHELIOGRAPH [PDF]

, 1977
1977-01A computer program to improve dirty solar maps on the basis of measured phase errors was developed for the 8-cm radioheliograph at Toyokawa. The radioheliograph is a simple T-shaped phase-switching interferometer, and is not equipped with a phase ...

Spectral Analysis of Solar Radio Type III Bursts from 20 kHz to 410 MHz

The Astrophysical Journal, 2022
We present the statistical analysis of the spectral response of solar radio type III bursts over the wide frequency range between 20 kHz and 410 MHz. For this purpose, we have used observations that were carried out using both spaced-based (Wind/Waves ...
