A New Declining Phase Precursor and an Early Prediction of Cycle 26 Maximum

The Astrophysical Journal
The overall level of solar activity as seen in the sunspot number (SSN) record paces both the state of the ionosphere and the amplitude and occurrence rates of extreme space weather events.

Photospheric high-frequency acoustic power excess in sunspot umbra: signature of magneto-acoustic modes [PDF]

, 2013
We present observational evidence for the presence of MHD (magnetohydrodynamic) waves in the solar photosphere deduced from SOHO/MDI (Solar and Heliospheric Observatory/Michelson Doppler Imager) Dopplergram velocity observations.

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.

Outcomes of Recurrent Laryngeal Nerve Reinnervation for Pediatric Unilateral Vocal Fold Paralysis

The Laryngoscope, EarlyView.
The objective of this study was to describe voice outcomes from the largest single‐center, single‐surgeon experience with recurrent laryngeal nerve reinnervation for pediatric unilateral vocal fold paralysis. In 102 patients who underwent reinnervation, we demonstrate that reinnervation is an effective and durable intervention for treatment of ...

Understanding Solar Activity after the Maunder Minimum: Sunspot Records by Rost and Alischer

The Astrophysical Journal
The Maunder Minimum was a period with significantly reduced solar activity between 1645 and 1715, approximately. The transition between the low solar activity in the Maunder Minimum and the subsequent “normal” regime of solar activity was gradual ...

Response of Extreme Precipitation to Solar Activity and El Nino Events in Typical Regions of the Loess Plateau

Advances in Meteorology, 2017
Extreme climatic oscillation has been the subject of global attention. The purpose of this study is to explore the response of extreme precipitation to solar activity and El Nino events in typical regions of the Loess Plateau—a case study in the Yan’an ...

Slow‐Phase Nystagmus Velocity as a Risk Factor for Lateral Canal BPPV Recurrence

The Laryngoscope, EarlyView.
This study investigated slow‐phase nystagmus velocity (SPV) at initial diagnosis as an objective vestibular predictor for the recurrence of lateral semicircular canal benign paroxysmal positional vertigo (BPPV). Binomial logistic regression analysis demonstrated that an elevated initial SPV is a novel, independent risk factor for recurrence ...

FUNCTIONAL SUNSPOT EQUILIBRIA [PDF]

Consider a one step forward looking model where agents believe that the equilibrium values of the state variable are determined by a function whose domain is the current value of the state variable and whose range is the value for the subsequent period ...

Prime editing in neuropsychiatric disorders: From mutation‐specific target selection to clinical translation

Neuroprotection, EarlyView.
Abstract Prime editing, a novel clustered regularly interspaced short palindromic repeats (CRISPR)‐based technology, fuses a reverse transcriptase (RT) to an engineered CRISPR‐associated protein 9 (Cas9) and uses a prime editing guide RNA (pegRNA)‐encoded template.
