Elemental Abundances at Coronal Hole Boundaries as a Means to Investigate Interchange Reconnection and the Solar Wind

The Astrophysical Journal
The origin of the slow solar wind is not well understood, unlike the fast solar wind that originates from coronal holes. In situ elemental abundances of the slow solar wind suggest that it originates from initially closed field lines that become open ...

The non-negligible effect of magnetic holes on the magnitude-of-B magnetic power spectral density of the fast Alfvenic coronal-hole-origin solar wind at 1 AU

Frontiers in Astronomy and Space Sciences
To estimate the effects of magnetic holes on the magnitude of B magnetic power spectral density, a 2-day interval of fast coronal-hole-origin plasma at 1 AU is examined. The magnetic holes are identified and removed from the magnetic time series, and the

Parameters of the Magnetic Flux inside Coronal Holes

, 2009
Parameters of magnetic flux distribution inside low-latitude coronal holes (CHs) were analyzed. A statistical study of 44 CHs based on Solar and Heliospheric Observatory (SOHO)/MDI full disk magnetograms and SOHO/EIT 284\AA images showed that the density

Use of microsurfaced acellular dermal matrix for the generation of site‐appropriate keratinized tissue in soft tissue augmentation healing: Proof of concept

Clinical Advances in Periodontics, EarlyView.
Abstract Background Autogenous grafts remain the gold standard for soft tissue augmentation, but allogeneic dermal matrices (ADMs) offer a viable alternative. Limited cellular infiltration and neovascularization restrict ADM efficacy; this study investigates a novel microsurfaced ADM (MS‐ADM) designed to address these limitations. Methods This 180‐day,

Microwave Bright Points with Multiple Periodic Oscillations in the Solar Polar Coronal Hole during Solar Cycle Minimum

The Astrophysical Journal
During solar cycle minimum, polar coronal holes show a prominent radio brightening cap. The analysis of polar microwave enhanced radiation in polar coronal holes is helpful for understanding the magnetic field characteristics and the origin of the solar ...

Velocity Structure of Jets in Coronal Hole

, 2007
Velocity structures of jets in a coronal hole have been derived for the first time. Hinode observations revealed the existence of many bright points in coronal holes. They are loop-shaped and sometimes associated with coronal jets.

A guide to neuromodulation in drug‐resistant epilepsy

Epileptic Disorders, EarlyView.
Abstract Neuromodulation is approved for the treatment of drug‐resistant epilepsy. It has been increasingly utilized over the past two decades with the approval of deep brain stimulation (DBS) and responsive neurostimulation (RNS) in addition to vagus nerve stimulation (VNS)—particularly in patients who are not deemed to be good resective surgical ...

Solar Origins of Short-Term Periodicities in Near-Earth Solar Wind and Interplanetary Magnetic Field

Applied Sciences
This study investigates the solar origins of short-term periodicities in the near-Earth solar wind and interplanetary magnetic field (IMF) using long-term observations (1995–2024) and Potential Field Source Surface modeling.
