Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Iliotibial Band Meniscal Augmentation for a Revision Inside‐Out Lateral Meniscus Radial and Horizontal Cleavage Tear Repair

open access: yesArthroscopy Techniques, EarlyView.
Abstract Surgical repair of complex meniscal tears can be quite challenging, especially in the case of a failed meniscus repair. In this setting, meniscal volume may be lost, leading to an increased risk of osteoarthritis development. To prevent this from occurring, care should be taken to revise these complex tears using an inside‐out technique ...

Arthroscopic Anterior and Posterior Glenohumeral Capsular Augmentation With Gracilis Allograft

open access: yesArthroscopy Techniques, EarlyView.
Abstract Multidirectional instability in patients with connective tissue disorders such as Ehlers‐Danlos syndrome (EDS) is difficult to treat due to poor tissue quality and frequent failure of standard repairs. We describe an arthroscopic technique using gracilis tendon allografts to perform an anterior and posterior capsular augmentation in the ...

Arthroscopic‐Assisted Triple‐Bundle Reconstruction for Acromioclavicular Joint Dislocation

open access: yesArthroscopy Techniques, EarlyView.
Abstract This article describes a practical technique for treating acute and chronic acromioclavicular joint dislocations. With the aid of intraoperative arthroscopy, tunnels were drilled on the clavicle and coracoid process, and Tightrope and Endobutton devices were introduced to anatomically reconstruct the conoid and trapezoid ligaments ...

Technique for Lateral Opening Wedge Distal Femoral Osteotomy Using Patient‐Specific Instrumentation for Genu Valgum and Patellar Instability

open access: yesArthroscopy Techniques, EarlyView.
Abstract Recurrent lateral patellar instability poses a technical challenge to orthopaedic surgeons. Isolated soft‐tissue procedures through medial patellofemoral ligament reconstruction or lateral release show unacceptably high failure rates. Lateral opening wedge distal femoral osteotomy addresses underlying bony malalignment and reinforces the soft ...

New views on the emission and structure of the solar transition region

open access: yes, 2010
The Sun is the only star that we can spatially resolve and it can be regarded as a fundamental plasma laboratory of astrophysics. The solar transition region (TR), the layer between the solar chromosphere and corona, plays an important role in solar wind

Fast X-Ray Variability from the Coronae of Supermassive Black Holes

open access: yesThe Astrophysical Journal Letters
We present the first systematic study of short-timescale X-ray variability in radio-quiet active galactic nuclei (AGN), utilizing archival Chandra observations of approximately 3000 broad-line AGN selected from the Sloan Digital Sky Survey and Dark ...

Physical properties of solar polar jets: A statistical study with Hinode XRT data

open access: yes, 2015
The target of this work is to investigate the physical nature of polar jets in the solar corona and their possible contribution to coronal heating and solar wind flow based on the analysis of X-ray images acquired by the Hinode XRT telescope. We estimate

Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.
