The physical origin of aneurysm growth, dissection, and rupture [PDF]

arXiv, 2023
Rupture of aortic aneurysms is by far the most fatal heart disease, with a mortality rate exceeding 80%. There are no reliable clinical protocols to predict growth, dissection, and rupture because the fundamental physics driving aneurysm progression is unknown.

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

Advanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Understanding the dynamics of support seeking in women with lived experience of non‐physical intimate partner violence (IPV) and the service responses—A qualitative study

Australian Journal of Social Issues, Volume 57, Issue 4, Page 861-879, December 2022., 2022
Abstract Non‐physical abuse is a form of intimate partner violence (IPV), which negatively impacts physical and mental well‐being. The study objectives were to understand the process of support seeking amongst women who experience non‐physical IPV. Interviews were conducted with women who have experience of non‐physical IPV and support workers.

Isthmus Dependent Atrial Flutter Cycle Length Correlates with Right Atrial Cross-Sectional Area

Indian Pacing and Electrophysiology Journal, 2009
Background: Right atrial flutter cycle length can prolong in the presence of antiarrhythmic drug therapy. We hypothesized that the cycle length of right atrial isthmus dependent flutter would correlate with right atrial cross-sectional area measurements.

Virtualizing clinical cases of atrial flutter in a fast marching simulation including conduction velocity and ablation scars

Current Directions in Biomedical Engineering, 2015
Diagnosis of atrial flutter caused by ablation of atrial fibrillation is complex due to ablation scars. This paper presents an approach to replicate the clinically measured flutter circuit in a dynamic computer model.

Noise-induced self-oscillation (flutter) suppression in the Keldysh model [PDF]

arXiv, 2021
An equation for the evolution of the energy of a dynamical system (Keldysh model with one degree of freedom), which contains a white noise source, is constructed. It is shown that self-oscillations (flutter) are suppressed if the intensity of white noise exceeds a critical value.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Study on coupled mode flutter parameters of large wind turbine blades

Scientific Reports
As the size of wind turbine blades increases, the flexibility of the blades increases. In actual operation, airflow flow can cause aerodynamic elastic instability of the blade structure.

Energy harvesting below the onset of flutter [PDF]

, 2019
This work demonstrates preliminary results on energy harvesting from a linearly stable flutter-type system with circulatory friction forces. Harmonic external forcing is applied to study the energy flow in the steady sliding configuration. In certain parameter ranges negative excitation work is observed where the external forcing allows to pull part of

Nonlinear stability analysis of whirl flutter in a rotor-nacelle system

Nonlinear dynamics, 2018
Whirl flutter is an aeroelastic instability that affects propellers/rotors and the surrounding airframe structure on which they are mounted. Whirl flutter analysis gets progressively more complicated with the addition of nonlinear effects.
