Estimation of the Energy Involved in a Solar Coronal Mass Ejection Using Spectroscopic Observations in the 5303 Å Emission Line

The Astrophysical Journal Letters
While the amount of solar coronal energy flux leaving the “quiet” Sun, coronal holes, and active regions has been estimated by many, similar calculations for transients like coronal mass ejections (CMEs) based on observations are few. Using spectroscopic

Improvements on coronal hole detection in SDO/AIA images using supervised classification

Journal of Space Weather and Space Climate, 2015
We demonstrate the use of machine learning algorithms in combination with segmentation techniques in order to distinguish coronal holes and filaments in SDO/AIA EUV images of the Sun.

Lateral and Anterior Closing Wedge “9/9” Degree Osteotomy to Correct Both Tibia Vara and Excessive Tibial Slope

Arthroscopy Techniques, EarlyView.
Abstract High tibial osteotomy is a key option for patients with unicompartmental overload or instability. Although coronal correction for varus deformity is well established, excessive posterior tibial slope (PTS) is increasingly recognized as a contributor to anterior cruciate ligament graft failure.

Arthroscopy‐Assisted Type 2 Posterior Horn Lateral Meniscus Transtibial Root Repair And Concurrent Inside‐Out Lateral Meniscus Horizontal Cleavage Tear Repair With an Anterolateral Ligament Reconstruction Utilizing Iliotibial Band Autograft

Arthroscopy Techniques, EarlyView.
Abstract The anterior cruciate ligament (ACL) and anterolateral ligament (ALL) play key roles in maintaining rotational stability of the knee joint. Injuries that cause ACL tears have been shown to also frequently compromise the integrity of the ALL.

The variation of coronal holes with solar cycle

Coronal holes are commonly known to be the source of the open magnetic flux and the high-speed solar wind. In EUV and X-ray emission lines, coronal holes are seen as the regions with reduced emission due to lower temperatures and electron density than ...

Field-aligned currents are strongly modulated by corotating solar wind high-speed streams

Journal of Space Weather and Space Climate
Birkeland field-aligned currents (FACs) are associated with solar wind-magnetosphere energy coupling leading to substorms/convection events. FAC intensity enhancements have been studied during geomagnetic storms driven by interplanetary coronal mass ...

Automated coronal hole identification via multi-thermal intensity segmentation

Journal of Space Weather and Space Climate, 2018
Coronal holes (CH) are regions of open magnetic fields that appear as dark areas in the solar corona due to their low density and temperature compared to the surrounding quiet corona.

Treatment of Developmental Dysplasia of the Acetabulum by Hip Arthroscopic Acetabuloplasty Combined With Labral Repair, Cam and Pincer Osteoplasty, Collagen‐Induced Autologous Chondroplasty, and Capsule Suture

Arthroscopy Techniques, EarlyView.
Abstract Developmental hip dysplasia due to insufficient acetabular coverage and excessive pressure on the femoral head can easily lead to labral tears, damage to the labrum–cartilage junction, cam and pincer deformities, and joint capsule laxity. This may ultimately result in osteoarthritis.
