The Astrophysical JournalBipolar magnetic regions (BMRs) that appear on the solar photosphere are surface manifestations of the Sun’s internal magnetic field. With modern observations and continuous data streams, the study of BMRs has moved from manual sunspot catalogs to ...

Atmosphere(1) Introduction: The subject of the present study concerns the analysis of the existence and long time evolution of the solar ~200 yr (de Vries/Suess) and ~2400 yr (Hallstadt) cycles during the recent part of the Wurm ice epoch and the Holocene, as well

Journal of Paediatrics and Child Health, EarlyView.ABSTRACT Background Retinopathy of prematurity (ROP) is a neurovascular disorder that may affect not only the retina but also the brain structures involved in visual processing. The relationship between ROP severity and the volumetric development of these regions remains unclear.

The Astrophysical JournalWe explore what fraction of delta sunspots with a sharp polarity inversion line (PIL) in photospheric magnetograms are produced by a writhe kink in an emerging twisted flux rope.

Detecting Periodicity of a General Stationary Time Series via AR(2)‐Model Fitting
Journal of Time Series Analysis, EarlyView.ABSTRACT Estimating the periodicity of a stationary time series via fitting a second‐order stationary autoregressive (AR(2)) model has been initiated by the seminal paper of Yule (1927). We investigate properties of this procedure when applied to general stationary processes possessing a spectral density with a dominant peak at some unknown frequency ...

Duplicitous Remembrance: Confessing Self‐Deception with Augustine
Modern 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.

Surface Evolution of the Sun's Magnetic Field: A Historical Review of the Flux-Transport Mechanism
Living Reviews in Solar Physics, 2005 This paper reviews our attempts to understand the transport of magnetic flux on the Sun from the Babcock and Leighton models to the recent revisions that are being used to simulate the field over many sunspot cycles.

Long‐term stability of transcrestal sinus augmentation
Periodontology 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 ...
