Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

OPTIMAL DESIGN OF DAMPED DYNAMIC VIBRATION ABSORBER FOR DAMPED PRIMARY SYSTEMS

Transactions of the Canadian Society for Mechanical Engineering, 2010
This study focuses on the optimum design of the damped dynamic vibration absorber (DVA) for damped primary systems. Different from the conventional way, the DVA damper is connected between the absorber mass and the ground. Two numerical approaches are employed.

Dynamic condensation in a damped system through rational selection of primary degrees of freedom

Journal of Sound and Vibration, 2012
Abstract Various system reduction methods have been proposed to calculate eigenvalues and eigenvectors with computational efficiency. In the case of system condensation, the method of selecting proper primary degrees of freedom (PDOFs) is crucial because they are closely related to the accuracy and reliability of eigensystem prediction in a reduced ...

Exact Algebraic Solution of an Optimal Double-Mass Dynamic Vibration Absorber Attached to a Damped Primary System

The Proceedings of the Dynamics & Design Conference, 2018
AbstractThis article presents exact algebraic solutions to optimization problems of a double-mass dynamic vibration absorber (DVA) attached to a viscous damped primary system. The series-type double-mass DVA was optimized using three optimization criteria (the H∞ optimization, H2 optimization, and stability maximization criteria), and exact algebraic ...
