Cost‐utility analysis of add‐on Qili Qiangxin capsules in chronic heart failure with reduced ejection fraction in China

open access: yesESC Heart Failure, EarlyView.
Abstract Aims The study aimed to analyse the cost‐utility of Chinese patent medicine Qili Qiangxin (QLQX) capsules in heart failure with a reduced ejection fraction from the healthcare payer's perspective. Methods and results From the perspective of the healthcare payer, a Markov model was established to estimate the cost‐utility of adding QLQX ...

Elucidating Parasitic Currents in Proton‐Exchange‐Membrane Electrolytic Cells via Physics‐Based and Data‐Driven Modeling

open access: yesElectrochemical Science Advances, EarlyView.
ABSTRACT Proton‐exchange membrane (PEM) water electrolysis is pivotal for green hydrogen production, necessitating accurate predictive models to manage their non‐linearities and expedite commercial deployment. Understanding degradation mechanisms through macro‐scale modeling and uncertainty quantification (UQ) is crucial for advancing this technology ...

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Challenges in High‐Fidelity Implicit Block‐Based Numerical Simulation of Dynamic Out‐of‐Plane Two‐Way Bending in Unreinforced Brick Masonry Walls

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study deals with the high‐fidelity block‐based finite element simulation of dynamic out‐of‐plane (OOP) responses of unreinforced masonry (URM) walls, explicitly focusing on two‐way bending behaviors under seismic loads, which is a common critical failure mode in real‐world masonry structures.

Experimental Investigation of an Earthquake‐Resistant Steel Bridge Substructure System

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The grouted shear stud connection has been experimentally shown to provide two‐column steel bridge bent systems with seismic resistance. It achieves this by relocating the plastic hinging to the column section, thereby mobilizing the full strength and ductility of the steel columns.

Multi‐Axial Subassemblage Testing System for Hybrid Simulation With Large‐Scale Structural Components

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This article presents the Multi‐Axial Subassemblage Testing facility of ETH Zurich, Switzerland (ETHZ‐MAST) for quasi‐static testing and hybrid simulation (HS) of large‐scale structural components and assemblies. The ETHZ‐MAST features a 6‐degrees‐of‐freedom (DOFs, 3 translations and 3 rotations) loading system based on a steel crosshead and ...

Friction Characterization and Mitigation in Large‐Scale 6DOF Multi‐Axial Hybrid Simulation

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In the last few decades, hybrid simulation has become widely used for understanding the response of structural components and systems under extreme loading conditions. Large‐scale, three‐dimensional (3D), multi‐axial testing facilities with six degrees of freedom (6DOF) are versatile testing systems that can be used for testing a variety of ...

Enhanced Objectivity of AHP for More Reliable Solar Farm Site Selection

open access: yesEnergy Science &Engineering, EarlyView.
While the analytic hierarchy process (AHP) was originally designed for subjectively relatable criteria, there may also be objectively defined relationships or consensus on certain criteria pairs. To incorporate these objective relationships and consensuses, this study introduces the analytical hierarchy process with optimized hierarchy (AHP‐OH).

Experimental Study on Instability Mechanism of Red Shale Roadway Under Dynamic Disturbance

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT To delve into the instability mechanism of the surrounding rock in red shale roadways, a bespoke device was chosen to fabricate a physical model, and a similar experiment was conducted with a blasting‐induced disturbance. A meticulous examination was performed on the evolution of surface fractures and the macroscopic failure patterns of the ...
