High Rate of Return to Sport in Competitive Athletes Undergoing Periacetabular Osteotomy With Concomitant Hip Arthroscopy

open access: yesArthroscopy, EarlyView.
Purpose To report the return‐to‐sport rate of competitive athletes with hip dysplasia, in relation to their preoperative level of competition, who underwent hip arthroscopy with concomitant periacetabular osteotomy (HA + PAO). Methods Patients participating in competitive sports who underwent HA + PAO for the correction of hip dysplasia between January

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

open access: yesCarbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Enhancing Evidence Generation by Linking Randomized Clinical Trials to Real‐World Data: The INVESTED‐Medicare Linkage Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Real‐world evidence (RWE) derived from real‐world data (RWD) can complement randomized controlled trials (RCTs), yet the validity of RWD relative to RCT data remains insufficiently characterized. We obtained post hoc consent and linked individual participant data from the US‐based INVESTED trial (2016–2019) with Medicare fee‐for‐service claims (2012 ...

Evaluation of Virtual Refrigerant Mass Flow Sensors [PDF]

open access: yes, 2012
Refrigerant mass flow rate is an important measurement for monitoring equipment performance and enabling fault detection and diagnostics. However, a traditional mass flow meter is expensive to purchase and install. A virtual refrigerant mass flow sensor (

Bondi-Sachs metrics and photon rockets

open access: yes, 2011
We study the Bondi-Sachs rockets with nonzero cosmological constant. We observe that the acceleration of the systems arises naturally in the asymptotic symmetries of (anti-) de Sitter spacetimes.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

History of Solid Rockets [PDF]

open access: yes, 2017
Solid rockets were created by accident and their design and uses have evolved over time. Solid rockets are more simple and reliable than liquid rockets, but they have reduced performance capability.

Stopping Power of Electron Liquid for Slow Quantum Projectiles

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We revisit the problem of the deceleration of a charge moving in a medium. In the low‐velocity limit of the projectile, we construct the fully nonlinear (in the charge–target interaction) theory of the stopping power (SP), which goes beyond the classical Ehrenfest dynamics.
