Recurrent magnetic activity, sunspot number and its rate of decline

, 1974
Power spectral densities computed from low-latitude horizontal intensity of the Earth's magnetic field over two-year periods of declining phases of solar cycles 16 to 19 show a close relationship with the maximum relative sunspot number of the following ...

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 ...

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.

Changing relationships between sunspot number, total sunspot area and F 10.7 in cycles 23 and 24

, 2017
This article is an update of a study (Tapping and Vald\ue8s in Solar Phys.272, 337, 2011) made in the early part of Cycle 24 using an intercomparison of various solar activity indices (including sunspot number and the 10.7 cm solar radio flux), in which ...

CRB1‐Associated Inherited Retinal Dystrophies: Prospective Natural History Study With 4 Years of Follow‐Up

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background The lack of validated and sensitive clinical endpoints remains a major challenge in the design of gene therapy trials for inherited retinal dystrophies (IRDs). This prospective longitudinal cohort study describes the natural disease progression of IRDs caused by pathogenic mutations in the Crumbs homologue 1 (CRB1) gene, and ...

Randomised Clinical Trial to Evaluate the Efficacy of Acetazolamide for the Treatment of Cystoid Fluid Collections in X‐Linked Retinoschisis: The AXIS Trial

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background This trial aimed to evaluate the efficacy of oral acetazolamide in reducing cystoid fluid collections (CFC) and improving visual function in patients with X‐linked retinoschisis (XLRS). Methods In this investigator‐initiated, single centre, open‐label, randomised controlled trial, XLRS patients aged ≥ 12 years with fovea‐involving ...

Solar Observations by Angelo Secchi: An Analysis of His Diary and Annotations in His Sunspot Drawings

The Astrophysical Journal
Angelo Secchi, a pioneer in solar physics, provided an extensive and regular record of sunspot observations spanning the period 1858–1878. This study analyzes the handwritten records by Secchi and collaborators in the form of drawings and an observation ...

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 ...

Assessment of sunspot number cross-calibration approaches [PDF]

Context. Group sunspot number data form the longest record of direct observations of solar activity and variability. However, the observations were conducted by many observers using different telescopes and at diverse locations, which necessitates their ...

Geopolitical Risk and Domestic Bank Deposits

Financial Management, EarlyView.
ABSTRACT We investigate the relationship between global geopolitical risk and bank deposit flows across a wide panel of European countries. Motivated by the pivotal role of deposit stability for financial intermediation and systemic resilience, we explore whether geopolitical shocks alter depositors’ portfolio choices.
