Ten‐year outcomes of combined ACLR and lateral extra‐articular tenodesis: A systematic review

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This systematic review evaluates long‐term outcomes after anterior cruciate ligament reconstruction (ACLR) with lateral extra‐articular tenodesis (LET), including patient‐reported outcome measures (PROMs), failure rates, objective knee scores and radiographic osteoarthritis (OA).

Pure Gaussian Apodisation Reduces Integral Crosstalk Sensitivity in Quantitative NMR

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Exponential apodisation redistributes peak area away from its centre, which increases crosstalk with neighbouring peaks and reduces integral trueness when integrating between defined regions. A pure Gaussian apodisation limits wing growth: Crosstalk between peaks is not worsened, and trueness is conserved during integration.

Quantitative Susceptibility Mapping of Kidney Stones: An Ex Vivo MRI Phantom Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To visualize and characterize the five most common kidney stone types based on their magnetic susceptibilities in MRI using QSM. Methods Three water‐based agar phantoms were constructed, containing a total of 53 ex vivo kidney stones of varying types and sizes.

Robust Linearization and Eigenvalue Analysis of General Complex Constrained Multibody Systems

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The derivation of linearized equations and subsequent eigenvalue analysis is the basis for tasks such as frequency‐domain response analysis, control design, and stability assessment for mechanical systems. However, for general multibody systems with redundant or nonholonomic constraints, practical challenges persist in achieving numerically ...

High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

open access: yesPolymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

A Dual Country Validation of the Basic Psychological Needs Satisfaction and Frustration Scale: A New Focus on School Relationships

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT Despite the growing interest in basic psychological needs within educational settings, existing measures fail to distinguish between students' relationships with teachers and classmates, limiting the understanding of how different social dynamics uniquely impact need satisfaction and frustration during adolescence.
