Defining sagittal knee phenotypes via monopedal static anterior tibial translation. Part 2: The assessment‐led personalization (ALP) system for indication and correction target planning in slope‐reducing osteotomy

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Current decision‐making for slope‐reducing osteotomy (SRO) often relies on isolated posterior tibial slope (PTS) thresholds, potentially misidentifying patients with acquired soft‐tissue decompensation or possibly overtreating those with an asymptomatic, inherently hyperlax baseline.

Management of increased posterior tibial slope in ACL deficiency: A narrative review and recommendation of the Osteotomy Committee of the German Knee Society

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Increased posterior tibial slope (PTS) is a known risk factor for anterior cruciate ligament (ACL) deficiency and graft failure after ACL reconstruction (ACLR). Although many studies investigated different aspects related to the PTS, there is still a lack of comprehensive recommendations and practical guidelines, especially with regard to ...

Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

open access: yesLaser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Side‐DBR Guided Exciton‐Polariton Lasing With Near‐Field Mode Imaging in an InGaN Thin‐Film Ridge Waveguide

open access: yesLaser &Photonics Reviews, EarlyView.
Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Zero‐Dimensional Perovskite‐Inspired Scintillator‐Based High‐Radiation‐Resistant Radionuclide Analyzer Free From Irreversible Degradation

open access: yesLaser &Photonics Reviews, EarlyView.
A zero‐dimensional perovskite‐inspired scintillator (Cs3Cu2I5) is developed as a high‐radiation‐resilient radionuclide analyzer capable of operating under extreme γ‐ray environments. Even after 200 kGy irradiation, the device fully restores its original spectroscopic performance through simple thermal annealing, demonstrating intrinsic defect ...

Disposition Model for Permafrost Degradation in Mountainous Regions

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and
