Maximum Coronal Mass Ejection Speed as an Indicator of Solar and Geomagnetic Activities

, 2011
We investigate the relationship between the monthly averaged maximal speeds of coronal mass ejections (CMEs), international sunspot number (ISSN), and the geomagnetic Dst and Ap indices covering the 1996-2008 time interval (solar cycle 23).

Long-term Evolution of Sunspot Magnetic Fields [PDF]

, 2010
Independent of the normal solar cycle, a decrease in the sunspot magnetic field strength has been observed using the Zeeman-split 1564.8nm Fe I spectral line at the NSO Kitt Peak McMath-Pierce telescope.

ACLY‐Driven Metabolic Reprogramming Promotes Histone Acetylation and Inflammation‐Associated Fibrosis in Chronic Kidney Disease

Advanced Science, EarlyView.
This study reveals a citrate–ACLY–H3K27ac metabolic–epigenetic axis driving inflammatory gene activation and kidney fibrosis, highlighting ACLY inhibition as a potential therapeutic strategy for chronic kidney disease (CKD). ABSTRACT The mechanisms by which metabolic stress drives epigenetic dysregulation and fibrosis in chronic kidney disease (CKD ...

Beyond the Ban—Shedding Light on Smallholders' Price Vulnerability in Indonesia's Palm Oil Industry

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Indonesian government imposed a palm oil export ban in April 2022 to address rising cooking oil prices. This study explores oil palm smallholders' vulnerability to the policy using descriptive statistics, Lasso, and post‐Lasso OLS regressions.

Reconstruction of solar activity for the last millennium using $^{10}$Be data

, 2003
In a recent paper (Usoskin et al., 2002a), we have reconstructed the concentration of the cosmogenic $^{10}$Be isotope in ice cores from the measured sunspot numbers by using physical models for $^{10}$Be production in the Earth's atmosphere, cosmic ray ...

Recalibration of the Sunspot-Number: Status Report

Solar Physics, 2023
AbstractWe report progress on the ongoing recalibration of the Wolf sunspot number ($S_{\mathrm{N}}$SN) and group-sunspot number ($G_{\mathrm{N}}$GN) following the release of version 2.0 of$S_{\mathrm{N}}$SNin 2015. This report constitutes both an update of the efforts reported in the 2016 Topical Issue of Solar Physics and a summary of work by the ...

Hyperreflective Foci in the Inner Nuclear Layer: Proof‐of‐Concept for an Optical Coherence Tomography Derived Microglia‐Related Marker in Multiple Sclerosis

Annals of Neurology, EarlyView.
The role of microglia has emerged as a critical driver of disease progression in multiple sclerosis (MS), but we lack broadly applicable monitoring tools. Here, we investigated whether hyperreflective foci (HRF), as detected by optical coherence tomography (OCT) within the inner nuclear layer (INL) of the retina, can be used as a marker for microglial ...
