Design and Multibody Dynamics Modeling of a Novel High‐Static‐Low‐Dynamic‐Stiffness Vibration Isolation Mechanism Based on Euler Buckling Characteristics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibration isolation has long been a critical area of research, with the design of isolators based on the mechanical properties of Euler buckling beams representing one of the primary approaches. Traditionally, the focus has been on utilizing the negative stiffness characteristics of a post‐buckled Euler beam in parallel with positive stiffness

Optimization of Venting Units to Minimize the Dimensions of Explosive Zones

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT This contribution investigates how changes of standardized venting geometries affect the EX zone extension. CFD simulations are used to explore different venting unit geometries in order to reduce the experimental effort. The optimization of the venting unit geometries is analyzed separately from the dispersion of the hydrogen–air mixture into

A Comparison of FDS, ANSYS-CFX and Caelus for Car Park CO Ventilation [PDF]

Australasian Fluid Mechanics Conference (AFMC), 2020
A comparison of three computational fluid dynamics (CFD) solvers for carbon monoxide ventilation in a car park: FDS, ANSYS-CFX and Caelus is presented. FDS is a fire/smoke CFD solver used widely in the building services industry, whilst ANSYS-CFX and Caelus (an OpenFOAM R fork) are general purpose CFD solvers.

A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, Volume 293, Issue 15, Page 4604-4623, August 2026.
The Notch signaling pathway plays a crucial role in regulating endothelial biology. Notch signaling is sensitive to hemodynamic forces and governs mechanically driven cardiovascular development, physiology, and remodeling. This study reveals a non‐canonical role for the Notch ligand Jagged1 in endothelial mechanotransduction.

Allogeneic Immune Cell Perfusion Inhibits the Growth of Vascularized 3D In Vitro Tumor Models, Induces Vascular Regression and Desmoplasia, but Promotes Tumor Cell Invasion

Advanced Science, Volume 13, Issue 22, 17 April 2026.
This study presents a vascularized 3D tumor model to investigate immune–stromal–tumor interactions under allogeneic PBMC perfusion. While immune cells induced tumor shrinkage, they also promoted vascular regression, stromal activation, and cancer cell invasion.

Mechanistic Insights Into How Rewiring and Bifurcation Angle Affect DK‐Crush Stent Deployment

Catheterization and Cardiovascular Interventions, Volume 107, Issue 5, Page 1314-1323, April 1, 2026.
ABSTRACT Background Double kissing crush (DKC) is a preferred two‐stent technique for complex coronary bifurcation lesions. Proximal cell rewiring is routinely recommended to reduce technical failure, and DKC is considered effective across various bifurcation angles. However, it remains unclear whether this standard approach is optimal for all patients.
