PROGNOSES AND ANOMALY OF 24TH CYCLE OF SOLAR ACTIVITY
Odessa Astronomical Publications, 2014 Development of solar activity in 24th cycle has specific peculiarity – non-monotonous increasing of solar activity on grown phase which occurs for 1/3 number of all cycles.

Frontiers in Astronomy and Space Sciences, 2023 Sunspot records reveal that whilst the Sun has an approximately 11 year cycle of activity, no two cycles are of the same duration. Since this activity is a direct driver of space weather at Earth, this presents an operational challenge to quantifying ...

Modulation of the sunspot cycle [PDF]
Astronomy & Geophysics, 2010 Solar activity has been abnormally high for the last half-century, but the extremely feeble start of the latest 11-year cycle suggests that this episode is probably coming to an end. This prospect raises some fascinating and important issues, involving an extremely wide range of timescales, writes Nigel Weiss.

The Astrophysical Journal LettersTelescopic sunspot observations began in 1610 and captured subsequent solar cycles. In combination with proxy reconstructions on an annual scale, these data sets indicate a gradual transition between regular solar cycles and the Maunder Minimum.

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 ...

Timing terminators : forecasting sunspot cycle 25 onset [PDF]
, 2020 Recent research has demonstrated the existence of a new type of solar event, the “terminator.” Unlike the Sun’s signature events, flares and coronal mass ejections, the terminator most likely originates in the solar interior, at or near the tachocline ...

Does Correction Factor Vary with Solar Cycle? [PDF]
Journal of Astronomy and Space Sciences, 2012 Monitoring sunspots consistently is the most basic step required to study various aspects of solar activity. To achieve this goal, the observers must regularly calculate their own correction factor k and keep it stable. Relatively recently, two observing

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 ...

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 ...
