Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Electroosmotic Pressure-Driven Flow through a Slit Micro-Channel with Electric and Magnetic Transverse Field

open access: yesJournal of Applied Fluid Mechanics, 2019
In the present study, flow through two-dimensional microchannel under an axial electric field, transverse electric and magnetic fields and with axial pressure gradient has been investigated numerically.

Numerical study of magnetohydrodynamic duct flow at high Reynolds and Hartmann numbers [PDF]

open access: yesJournal of Fluid Mechanics, 2012
AbstractHigh-resolution direct numerical simulations are conducted to analyse turbulent states of the flow of an electrically conducting fluid in a duct of square cross-section with electrically insulating walls and imposed transverse magnetic field. The Reynolds number of the flow is $1{0}^{5} $ and the Hartmann number varies from $0$ to $400$.

Neuromuscular Electric Stimulation Improves Early Isometric Knee Strength After Anterior Cruciate Ligament Reconstruction and Repair: A Meta‐analysis of Randomized Controlled Trials

open access: yesArthroscopy, EarlyView.
Purpose To assess the effectiveness of neuromuscular electrical stimulation (NMES) on quadriceps strength and knee function after anterior cruciate ligament surgery. Methods A comprehensive search of PubMed, Ovid MEDLINE, and Embase from inception until February 2025 was conducted.

Initial treatment strategies and outcomes across haemodynamic thresholds and risk stratification in incident systemic sclerosis–associated pulmonary arterial hypertension: a EUSTAR analysis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Real‐world initial treatment strategies in SSc‐PAH remain incompletely described. We aimed to characterise these strategies across haemodynamic thresholds and risk strata and evaluate outcome associations. Methods We analysed treatment‐naïve SSc‐PAH patients in EUSTAR (2000–2021) fulfilling the 2022 haemodynamic definition.

Unsteady hydromagnetic couette flow due to ramped motion of one of the porous plates

open access: yesInternational Journal of Applied Mechanics and Engineering, 2013
An unsteady flow formation in Couette motion of an electrically conducting fluid subject to transverse magnetic field has been analyzed in the presence of suction/injection through the porous plates when one of the porous plates is in ramped motion.
