Complexity of solar variability, hydrology and climatic conditions as evidenced in the case of the Oulujoki and Kemijoki river basins, Northern Finland

Fennia: International Journal of Geography, 1983
The work concentrates on the dependency relations between the sunspot numbers, mean annual temperatures, annual precipitation rates, mean annual discharges (MQ), mean discharges of the flood months and coinci­dent monthly mean temperatures and winter ...

An Improved Prediction of Solar Cycles 25 and 26 Using the Informer Model: Gnevyshev Peaks and North–South Asymmetry

The Astrophysical Journal
Forecasting the amplitude and timing of the sunspot cycle is highly important for solar physics and space weather applications, but high-precision prediction of solar magnetic activity has remained an outstanding challenge.

Observations key to understanding solar cycles: a review

Frontiers in Astronomy and Space Sciences
A paradigm shift is taking place in the conception of solar cycles. In the previous conception, the changing numbers of sunspots over intervals of 9–14 years have been regarded as the fundamental solar cycle although two average 11-year cycles were ...

A novel myopathy with autophagic vacuoles associated with biallelic variants in CLN8

Brain Pathology, EarlyView.
We describe a novel adult‐onset myopathy with autophagic vacuoles and characteristic features of ceroid lipofuscinosis associated with biallelic CLN8 variants, seizures, and muscle weakness. Autophagosomal/lysosomal deposition of curvilinear, autofluorescent material containing the mitochondrial adenosine triphosphate (ATP) synthase membrane subunit c ...

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

Towards a Long-Term Catalogue of Sunspot-Group Positions and Rotation Velocities from Kanzelhöhe Observatory: Differential Rotation and Possible Torsional Oscillation Signatures During Solar Cycle 25

Universe
This study presents Solar Cycle (SC) 25 (2020–2025) results from the homogeneous Kanzelhöhe Solar Observatory (KSO) catalogue project and completes the analysis of SCs 19–25. Only SC18 remains to be processed before the catalogue is finalized.

Kcnv2 E151X Mouse Captures Hallmarks of KCNV2‐Associated Retinal Dystrophy

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background KCNV2‐associated retinopathy is a rare inherited retinal dystrophy caused by variants in the KCNV2 gene, leading to disrupted photoreceptor behaviour and progressive deterioration of vision. Patients have characteristic electroretinography abnormalities, including reduced cone response, delayed and reduced rod response to low light ...

Analysis and prediction of sunspot numbers

Geophysical Research Letters, 1985
An extension of anharmonic frequency analysis (AFA) is used to analyze and extrapolate the sunspot numbers. The higher resolution possible with this new approach in principle permits a better accuracy of the prediction for a given extrapolation range, provided the time series is stationary.
