The Solar Flux and Sunspot Number; A Long-Trend Analysis [PDF]
, 2018 We investigate the nature of monthly sunspot numbers and solar flux F10.7 by employing the linear and multiple regression techniques. We observed a brilliant correlation between monthly mean sunspot number and F10.7.

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.

Molecular Biomarkers in Meniere's Disease: A Scoping Review of Current Evidence
Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective Meniere's disease is a complex chronic inner ear condition that is characterized by vertigo, tinnitus, aural fullness, and progressive hearing loss. Currently, diagnostic strategies remain symptom‐driven, and treatments focus on management of discrete episodes rather than targeting underlying pathophysiology.

Re-examining sunspot tilt angle to include anti-Hale statistics [PDF]
, 2014 Sunspot groups and bipolar magnetic regions (BMRs) serve as an observational diagnostic of the solar cycle. We use Debrecen Photohelographic Data (DPD) from 1974-2014 that determined sunspot tilt angles from daily white light observations, and data ...

Pest Management Science, EarlyView.Adult Halyomorpha halys and Nezara viridula rapidly moved between berry crops and companion plants. Habitat use varied across environmental contexts, demonstrating that companion plantings function as dynamic elements in diversified cropping systems. Abstract BACKGROUND The brown marmorated stink bug Halyomorpha halys and the southern green stink bug ...

VIEW, EarlyView.Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Evidence for Solar Modulation on the Millennial-Scale Climate Change of Earth
Universe, 2020 In this study, we use available reconstructed data to investigate periodicities of solar activity (i.e., sunspot number) and the Earth’s climate change (temperatures of Lake Qinghai in China and Vostok in Antarctica, the GISP δ18O climate record of ...
