Cumulative Social Disadvantage and Disease Activity in Juvenile Idiopathic Arthritis: A Childhood Arthritis and Rheumatology Research Alliance Registry Study

open access: yesArthritis Care &Research, EarlyView.
Objective Social determinants of health (SDOH) contribute to juvenile idiopathic arthritis (JIA) disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship among cumulative social disadvantage ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

Symmetries for the Semi-Discrete Lattice Potential Korteweg–de Vries Equation

open access: yesMathematics
In this paper, we prove that the isospectral flows associated with both the x-part and the n-part of the Lax pair of the semi-discrete lattice potential Korteweg–de Vries equation are symmetries of the equation.

On some integrability aspects of the two-component Camassa–Holm equation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The integrability of the two-component Camassa–Holm shallow water equation with the gravity acceleration points downwards and upwards is investigated by prolongation structure theory and the geometric approach of pseudo-spherical surfaces.

Nonlinear contact Lax pair for (3+1)-dimensional integrable systems

open access: yes, 2019
The nonlinear contact Lax pair is a novel kind of Lax pair for integrable dispersionless systems in 3+1 dimensions. It is a key ingredient in the new construction of such systems introduced in the paper A.

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

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 ...
