FOXM1 Protects Against Myocardial Ischemia‐Reperfusion Injury in Rodent and Porcine Models by Suppressing MKRN1‐Dependent LKB1 Ubiquitination

Advanced Science, EarlyView.
FOXM1 maintains mitochondrial bioenergetic function by inhibiting MKRN1‐mediated ubiquitination of LKB1 in cardiomyocytes. Loss of FOXM1 in cardiomyocytes results in upregulation of MKRN1, which enhances LKB1 ubiquitination and disrupts AMPK signaling and energy metabolism pathways. Conversely, FOXM1 overexpression preserves mitochondrial bioenergetics

Projection effects in coronal mass ejections [PDF]

Astronomy & Astrophysics, 2007
Basic observational parameters of a Coronal Mass Ejection (CME) are its speed and angular width. Measurements of the CME speed and angular width are severely influenced by projection effects. The goal of this paper is to investigate a statistical relationship between the plane-of-sky speeds of CMEs and the direction of their propagation, hopefully ...

Disparity of turbinal bones in placental mammals

The Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Study of Evolution and Geo-effectiveness of Coronal Mass Ejection–Coronal Mass Ejection Interactions Using Magnetohydrodynamic Simulations with SWASTi Framework

The Astrophysical Journal
The geo-effectiveness of coronal mass ejections (CMEs) is a critical area of study in space weather, particularly in the lesser-explored domain of CME–CME interactions and their geomagnetic consequences.

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).

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.

FORECASTING A CORONAL MASS EJECTION'S ALTERED TRAJECTORY: ForeCAT [PDF]

, 2013
To predict whether a coronal mass ejection (CME) will impact Earth, the effects of the background on the CME's trajectory must be taken into account. We develop a model, ForeCAT (Forecasting a CME's Altered Trajectory), of CME deflection due to magnetic ...

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

physica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

An Improved Halo Coronal Mass Ejection Geoeffectiveness Prediction Model Using Multiple Coronal Mass Ejection Features Based on the DC-PCA-KNN Method

The Astrophysical Journal
Coronal mass ejections (CME) are regarded as the main drivers of geomagnetic storms (GSs). In the prediction of geoeffectiveness, various CME features have been introduced without adequately considering the geoeffectiveness of CMEs and strong ...

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

Small Methods, EarlyView.
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.
