Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
The Anatomical Record, EarlyView.Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

On a Schwarzian PDE associated with the KdV hierarchy [PDF]
, 2000 We present a novel integrable non-autonomous partial differential equation of the Schwarzian type, i.e. invariant under M\"obius transformations, that is related to the Korteweg-de Vries hierarchy.

Symbolic Computation of Lax Pairs of Partial Difference Equations using Consistency Around the Cube
, 2022 A three-step method due to Nijhoff and Bobenko & Suris to derive a Lax pair for scalar partial difference equations (PΔEs) is reviewed. The method assumes that the PΔEs are defined on a quadrilateral, and consistent around the cube.

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.Purpose To evaluate the clinical outcomes and survivorship of hip arthroscopy with simultaneous labral and ligamentum teres (LT) reconstruction for the treatment of irreparable labral and LT tears, with a minimum follow‐up of 2 years. Methods Prospectively collected data were retrospectively reviewed for patients who underwent combined arthroscopic ...

Weak Lax pairs for lattice equations [PDF]
, 2011 We consider various 2D lattice equations and their integrability, from the point of view of 3D consistency, Lax pairs and B¨acklund transformations. We show that these a concepts, which are associated with integrability, are not strictly equivalent.

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.Purpose To evaluate the inter‐rater reliability and sensitivity of the GNRB arthrometer compared with the KT1000 and clinical examination with the Lachman test for patients with an anterior cruciate ligament (ACL) injury. Methods Patients with ACL injury were examined preoperatively and postoperatively by 2 examiners.

Scientific Reports, 2023 In this paper, the exact solutions of generalized nonlinear Schrödinger (GNLS) equation are obtained by using Darboux transformation(DT). We derive some expressions of the 1-solitons, 2-solitons and n-soliton solutions of the GNLS equation via ...
