Shadow of slowly rotating Kalb-Ramond black holes

open access: yes
Real astronomical objects possess spin, yet deriving exact solutions for rotating black holes within gravitational theories is a formidable challenge.

Photocatalytic Solar Hydrogen Peroxide Production on Donor+Acceptor Linear Polymer Semiconductor Powders Reconfigurable by H‐Bonding and π‐Stacking Interactions

open access: yesAngewandte Chemie International Edition, EarlyView.
A linear polymer, poly(2,3‐dihydroxynaphthalene), when insolubilized, leads to self‐assembly into a hydroquinone–quinone donor+acceptor semiconducting architecture through H‐bonding and π‐stacking interactions. The polymer behaves as a heterogeneous photocatalyst in water for H2O2 production via water oxidation and O2 reduction under visible light.

Spin Dynamics of Excitons and Carriers in Mixed‐Cation MAxFA1–xPbI3 Perovskite Crystals: Alloy Fluctuations Probed by Optical Orientation

open access: yesAdvanced Physics Research, EarlyView.
The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.

Integrating whole‐bone and regional analyses to understand human scapular growth

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

Lateral Extra‐articular Tenodesis Using Knotless All‐Suture Anchor Fixation With Suture Tape: A Modified Technique for Augmenting Anterior Cruciate Ligament Reconstruction

open access: yesArthroscopy Techniques, EarlyView.
Abstract Lateral extra‐articular tenodesis has emerged as a valuable adjunct to anterior cruciate ligament reconstruction for mitigating residual rotational instability. We describe a modified lateral extra‐articular tenodesis technique utilizing an all‐suture knotless anchor with suture tape, which provides strong, flexible fixation with reduced soft ...

Knotless Suture Staple Remplissage for Hill‐Sachs Lesions in the Beach Chair Position

open access: yesArthroscopy Techniques, EarlyView.
Abstract The addition of remplissage to arthroscopic Bankart repair in the presence of a Hill‐Sachs lesion can help decrease recurrence of anterior shoulder instability. The remplissage procedure often involves passage of suture from anchors in the Hill‐Sachs lesion to the extra‐articular side of the shoulder capsule followed by knot tying.

Lateral Extra‐articular Tenodesis Utilizing Modified Ellison Technique With Knotless Anchor Fixation

open access: yesArthroscopy Techniques, EarlyView.
Abstract Lateral extra‐articular tenodesis (LET) to augment anterior cruciate ligament reconstruction significantly reduces graft failure rates. Although there are many techniques for lateral extra‐articular tenodesis, the modified Ellison technique provides numerous advantages as a distally fixed construct, including dynamic rotational stability ...
