Prospective randomised controlled trial comparing PLLA and PLDLA/HA/β‐TCP interference screws in anterior cruciate ligament reconstruction: CT scans, MRI and clinical outcomes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modifying interference screw composition may ensure better osteoconductive properties in order to reduce tunnel enlargement after anterior cruciate ligament (ACL) reconstruction. The primary and secondary purposes were to evaluate tunnel and screw volume changes in poly‐L‐lactide acid (PLLA) and poly‐D‐lactic acid + hydroxyapatite + β ...

Integrating Augmented Reality Into Otologic Cadaveric Surgical Training

The Laryngoscope, EarlyView.
This pilot study developed and implemented a specimen‐specific augmented reality (AR) workflow for cadaveric temporal bone dissection, using CT‐derived 3D models registered to each specimen and viewed intermittently through a Microsoft HoloLens 2 headset.

The observation of possible reconnection events in the boundary changes of solar coronal holes [PDF]

Coronal holes are large scale regions of magnetically open fields which are easily observed in solar soft X-ray images. The boundaries of coronal holes are separatrices between large scale regions of open and closed magnetic fields where one might expect

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

Laser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

Energy and Mass Transport Associated with Impulsive Spicular Flows in Solar Coronal Holes

The Astrophysical Journal Letters
How the solar atmosphere is heated from a temperature of about 5000 to 6000 K in the lower atmosphere to about 1–2 MK in the corona has challenged the astrophysical community for nearly 80 yr.

Study of the mechanism for solar wind formation [PDF]

Observations of the corona and solar wind are analyzed and compared with generalized results derived from laboratory-scale experiments. It was shown that a thermal pressure gradient can make a major contribution to a precipitating plasma of the solar ...

Shape‐Memory Collagen/Silk‐Fibroin Scaffold for Dura Sealing and Skull Base Regeneration

Small, EarlyView.
ABSTRACT When a skull base defect occurs, reconstruction is typically performed using a variety of autologous grafts, flaps, or synthetic materials. Failure to achieve appropriate management and closure can lead to serious consequences, such as cerebrospinal fluid (CSF) leakage and subsequent meningitis.

Pre‐task Vocabulary Support Enhances Lexical Learning but Dampens Positive Emotions: Interactive Task Implementation in English‐as‐a‐Foreign‐Language Classroom

TESOL Quarterly, EarlyView.
Abstract This classroom study explored the effects of vocabulary support on collocation learning and affective responses in task‐based language teaching (TBLT) among English‐as‐a‐foreign‐language (EFL) learners at a Japanese university. For this purpose, 68 EFL learners completed two interactive information‐gap tasks under either vocabulary‐support or ...

The Fiery Eyes of a Maenad: Origin Determination of Faceted Garnet Eye Inlays in a Roman Bronze Bust From Southern Tyrol

Archaeometry, EarlyView.
ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as
