Isometric and Quasi-isometric weighted composition operators

In this paper we characterize $m$-isometric and quasi-$m$-isometric weighted composition operators on the Hilbert space $L^2(μ)$. Also, we find that normal-$m$-isometry and normal quasi-$m$-isometry weighted composition operators have finite spectrum. Consequently we have the results for composition and multiplication operators.

Tissue‐Specific and Spatially Dependent Metabolic Signatures Perturbed by Injury in Male and Female Mice

Arthritis &Rheumatology, EarlyView.
Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

Combined Reconstruction of the Medial Patellofemoral Ligament and the Medial Quadriceps Tendon–Femoral Ligament Using Rectus Femoris Tendon Autograft

Arthroscopy Techniques, EarlyView.
Abstract Patellofemoral instability remains a challenging condition, especially in skeletally immature patients, who are at increased risk of recurrence. The medial patellofemoral ligament has historically been the focus of surgical reconstruction; however, recent anatomic studies have also highlighted the medial quadriceps tendon–femoral ligament as ...

Kinematic, Neuromuscular and Bicep Femoris In Vivo Mechanics during the Nordic Hamstring Exercise and Variations of the Nordic Hamstring Exercise

Muscles
The Nordic hamstring exercise (NHE) is effective at decreasing hamstring strain injury risk. Limited information is available on the in vivo mechanics of the bicep femoris long head (BFLH) during the NHE.

Isometric spectral subtriples

Journal of Mathematical Physics
We investigate the notion of subsystem in the framework of spectral triple as a generalized notion of noncommutative submanifold. In the case of manifolds, we consider several conditions on Dirac operators which turn embedded submanifolds into isometric submanifolds.

Arthroscopic Anterior and Posterior Glenohumeral Capsular Augmentation With Gracilis Allograft

Arthroscopy 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 ...

Percutaneous Double‐Loaded All‐Suture Knotless Anchor at the 6‐O'Clock Position for Shoulder Instability

Arthroscopy Techniques, EarlyView.
Abstract Glenohumeral instability is a common condition encountered by orthopaedic sports surgeons, particularly in young, active athletes. Initial management is nonoperative, consisting of physical therapy, but some patients may still require surgical intervention.

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

Arthroscopy 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 ...
