Probing Coronal Mass Ejection Inclination Effects with EUHFORIA

The Astrophysical Journal
Coronal mass ejections (CMEs) are complex magnetized plasma structures in which the magnetic field spirals around a central axis, forming what is known as a flux rope (FR).

In Situ and Operando Analytical Techniques of Single‐Atom Catalysts for Electrocatalytic CO2 Reduction

Small Methods, Volume 9, Issue 11, November 1, 2025.
Single‐atom catalysts (SACs) exhibit significant potential in CO2 reduction reactions (CO2RR) due to their unique geometric and electronic configurations. In situ and operando analytical techniques are essential for understanding CO2RR mechanisms and designing effective catalysts.

Estimating Coronal Mass Ejection Mass and Kinetic Energy by Fusion of Multiple Deep-learning Models

The Astrophysical Journal Letters, 2023
Coronal mass ejections (CMEs) are massive solar eruptions, which have a significant impact on Earth. In this paper, we propose a new method, called DeepCME, to estimate two properties of CMEs, namely, CME mass and kinetic energy.

A Type II Radio Burst Driven by a Blowout Jet on the Sun

The Astrophysical Journal, 2023
Type II radio bursts are often associated with coronal shocks that are typically driven by coronal mass ejections (CMEs) from the Sun. Here we conduct a case study of a type II radio burst that is associated with a C4.5-class flare and a blowout jet, but

Validating DIRECD: Statistical Evaluation of Coronal Mass Ejection Direction Estimates from Coronal Dimmings

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are among the most energetic phenomena in our solar system, with significant implications for space weather. Understanding their early dynamics remains challenging due to observational limitations in the low corona.

Dynamic disappearance of prominences and their geoeffectiveness [PDF]

Geofísica Internacional, 2008
We study 14 cases of dynamic “disparition brusque” (DBd), the sudden disappearance of quiescent filaments/prominences, during two solar minima: 1985-1986 and 1994.

Sustainable bioceramics, biopolymers, and composites for bone applications: From bench to production

International Journal of Applied Ceramic Technology, EarlyView.
Abstract In response to environmental challenges and primary resource scarcity, sustainable approaches that rely on recycling and reusing waste materials are becoming highly valuable and appealing options in modern society. These strategies have started being applied in biomaterials science, too, leading to the advent of new synergies between ...

On the Optimal Prediction of Extreme Events in Heavy‐Tailed Time Series With Applications to Solar Flare Forecasting

Journal of Time Series Analysis, EarlyView.
ABSTRACT The prediction of extreme events in time series is a fundamental problem arising in many financial, scientific, engineering, and other applications. We begin by establishing a general Neyman–Pearson‐type characterization of optimal extreme event predictors in terms of density ratios.

Hemispheric Distribution of Halo Coronal Mass Ejection Source Locations

The Astrophysical Journal
The hemispheric asymmetry of solar activity is one of the essential physical consequences of the interior dynamo process. However, the hemispheric distribution of halo coronal mass ejection (HCME) source locations has not been investigated in detail ...

Partially Erupted Prominence Material as a Diagnostic of Coronal Mass Ejection Trajectory

Space Weather, 2023
Coronal mass ejections (CMEs) are energetic releases of large‐scale magnetic structures from the Sun. CMEs can have impacts on spacecraft and at Earth. This trajectory is typically assumed to be radial, but often the CME moves outward with some spatial ...
