Hemispheric Asymmetry of Relative Sunspot Numbers during Solar Cycles 17–25

open access: yesThe Astrophysical Journal Supplement Series
The hemispheric asymmetry of solar activity provides important diagnostics of solar dynamo processes. In this study, we present a phase-resolved statistical analysis of hemispheric sunspot number asymmetry over solar cycles 17–25 (1939–2024), using ...

A Comparison of Rome Observatory Sunspot Area and Sunspot Number Determinations With International Measures, 1958-1998 [PDF]

open access: yes, 2005
Two changes in recording the sunspot record have occurred in recent years. First, in 1976, the longer-than-100-yr daily photographic record of the Royal Greenwich Observatory (RGO), used for determination of numbers and positions of sunspot groups and ...

Duplicitous Remembrance: Confessing Self‐Deception with Augustine

open access: yesModern Theology, EarlyView.
Abstract While self‐deception has long been a topic of interest in psychology and analytic philosophy—and increasingly in the academic study of theology and religion—direct engagement with Augustine on self‐deception remains underexplored in contemporary scholarship.

Predicting Interplanetary Shock Occurrence for Solar Cycle 25: Opportunities and Challenges in Space Weather Research

open access: yesSpace Weather
Interplanetary (IP) shocks are perturbations observed in the solar wind. IP shocks correlate well with solar activity, being more numerous during times of high sunspot numbers.

Long‐term stability of transcrestal sinus augmentation

open access: yesPeriodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...

Teacher Perspectives of Student Engagement in Data Practice Instruction: Two Classroom Conditions

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study examines high school science teachers' perceptions of student engagement in data practices across two instructional contexts: a scaffolded, student‐centered environment using the Science Practices Innovation Notebook (SPIN) and a business‐as‐usual (BAU) teacher‐led investigation.

Temporal Behavior and Latitudinal Relationships between Key Solar Parameters and Green Line Emissions in the Solar Corona

open access: yesThe Astrophysical Journal Letters
Understanding the link between solar parameters and their influence on green line emissions would help unravel the complexities of eruptive phenomena within the solar corona. This study explores the intricate relationship between green line emissions and

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.

Identification of cycles in sunspot numbers using percentage variance technique

open access: yes, 2020
In this paper, a method of percentage variance was used to identify the cycle in sunspot numbers given the assumption that the cycle is not known a priori.
