Cyclic sunspot activity during the first millennium CE as reconstructed from radiocarbon
Astronomy & AstrophysicsContext. Solar activity, dominated by 11-year cyclic evolution, has been observed directly since 1610 CE. Indirect cosmogenic proxy data have been used to reconstruct solar activity for millennia prior to 1610.

Investigation of HZE particle fluxes as a space radiation hazard for future Mars missions
Heliyon, 2019 Manned Mars missions planned in the near future of very low solar activity period and hence higher than acceptable radiation doses due mainly to the Galactic Cosmic Rays (GCR), would require special techniques and technological development for ...

THE RELATIVE SUNSPOT NUMBERS IN 2001 [PDF]
Publications of The Korean Astronomical Society, 2002 We have analyzed 209 data of daily sunspot observations made during the period of January 3 to December 31 In 2001 and presented the daily relative sunspot numbers. During the year of 2001, our annual average of relative sunspot numbers is found to be 92.2.

VIEW, EarlyView.In a cross‐sectional cohort of 104 participants, 7 T susceptibility separation MRI and diffusion imaging were combined with retinal imaging and visual evoked potentials to characterize visual pathway involvement in adrenomyeloneuropathy (AMN). Absolute diamagnetic susceptibility, a myelin‐associated measure, and fractional anisotropy (FA) showed ...

14C-Based Sunspot Numbers for the Last Millennium Encompass the Full Range of Variability: Extreme Value Theory [PDF]
We examine the statistical properties of extreme solar activity levels through the application of the extreme value theory to the annual sunspot number series reconstructed from 14C data spanning the last millennium. We have used the extreme value theory

VIEW, EarlyView.Abstract Age‐related macular degeneration (AMD) is a degenerative retinal disorder and a leading cause of global visual impairment, yet effective treatments remain limited. While gastritis is a prevalent clinical condition among older populations and has been associated with adverse effects on the central nervous system, its potential association with ...

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective Otolith is a critical component of the peripheral vestibular system responsible for detecting linear acceleration. Dysfunction of the otolith organs can lead to vertigo, balance disturbances, and gaze instability. By elucidating the physiological foundations and evaluating both current and emerging methods for assessing otolith ...

Fluctuating Sunspot Numbers Exhibit A Non-Markovian Damped Stochastic Process
, 2023 The rise and fall in the number of sunspots have served as a lynchpin in many investigations on solar dynamics. Arising from magnetic disturbances in the sun, variations in sunspot numbers have helped define a solar cycle of around eleven years which to ...
