Partial Eruption of Solar Filaments. I. Configuration and Formation of Double-decker Filaments
The Astrophysical Journal, 2023 Partial eruptions of solar filaments are the typical representatives of solar eruptive behavior diversity. Here we investigate a typical filament partial eruption event and present integrated evidence for the configuration of the pre-eruption filament ...

Sympathetic Partial Filament Eruptions Caused by the Interaction between Two Nearby Filaments
The Astrophysical Journal, 2023 To better understand the physical connections in sympathetic solar eruptions, we investigated the interaction between two nearby filaments and their successive partial eruptions in the active region (AR) NOAA 12866 on 2021 September 9 by using data from ...

Automated High-Precision Recognition of Solar Filaments Based on an Improved U2-Net
UniverseSolar filaments are a significant solar activity phenomenon, typically observed in full-disk solar observations in the H-alpha band. They are closely associated with the magnetic fields of solar active regions, solar flare eruptions, and coronal mass ...

High-altitude Spider-type Prominence above the Magnetic Null Point
The Astrophysical Journal, 2023 Rather unique observations of a high-altitude spider-type prominence in 2023 February are presented. The prominence or corresponding filament on the disk was not visible all the time but could appear and disappear in the course of a particular day ...

Network Jets as the Driver of Counter-streaming Flows in a Solar Filament/Filament Channel [PDF]
The Astrophysical Journal Letters, 2020 Abstract Counter-streaming flows in a small (100″ long) solar filament/filament channel are directly observed in high-resolution Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA) extreme-ultraviolet (EUV) images of a region of enhanced magnetic network.

The Kinematical Behavior of Solar Eruptive Filaments Affected by the Poloidal Magnetic Field
The Astrophysical JournalKinematics of solar eruptive filaments is one of the important diagnostic parameters for predicting whether solar eruptions would induce geomagnetic storms.

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

A Unified Model of Solar Prominence Formation with Self-consistent Heating
The Astrophysical JournalSeveral models have been proposed to explain the formation of solar prominences, among which the evaporation–condensation model and the direct injection model are the most popular ones.

Solvent‐Guided Chiral Assemblies and Chemical Doping of OEG‐Functionalized Conjugated Polymers
Advanced Materials, EarlyView.Solvent‐dependent aggregation pathways dictate whether conjugated polymers form chiral lyotropic liquid‐crystalline assemblies or achiral packed aggregates. Mapping solvent‐controlled β₁ and β2 states reveals that weaker backbone association favors β₁ aggregates and reorganizable twisted mesophases, whereas stronger backbone association favors β2 ...
