Analyzing the Impact of Network Vulnerability Propagation Factor on Cyber Security Risk Assessment in Online Social Networks

Engineering Reports, Volume 7, Issue 11, November 2025.
This study introduces the NVPF metric to quantify cybersecurity risks in online social networks, demonstrating that integrating behavioral, topological, and neighbor‐based features significantly enhances threat detection accuracy—achieving a 24.7% improvement over traditional methods.

Dual nature of mitral annular disjunction: normal variation or pathological precursor?

Hellenic Journal of Cardiology
The concept of mitral annular disjunction (MAD) has garnered significant attention due to its potential clinical implications. MAD refers to a spatial displacement of the hinge point of the mitral valve leaflets.

P4661Increased levels of sST2 in patients with mitral annulus disjunction and ventricular arrhythmias

European Heart Journal, 2019
Abstract Background Mitral annulus disjunction (MAD), a basal displacement of the mitral valve annulus, is described as a possible aetiology of sudden cardiac death. Stretch-induced fibrosis in the sub-valvular apparatus has been suggested as the substrate of arrhythmias.

MAD or MADness?

Cardiovascular Ultrasound
Mitral valve prolapse (MVP) is a common condition affecting approximately 3% of the population, typically with a benign clinical course. However, a small subset of patients (5–10%) may develop severe mitral regurgitation or arrhythmias, which can lead to

Stretch of the papillary insertion triggers reentrant arrhythmia: an in silico patient study

Frontiers in Physiology
BackgroundThe electrophysiological mechanism connecting mitral valve prolapse (MVP), premature ventricular complexes and life-threatening ventricular arrhythmia is unknown.

Blood-nulled late gadolinium enhancement increases sensitivity for subtle basal myocardial scar in mitral valve prolapse with annular disjunction

Radiology Case Reports
Mitral valve prolapse (MVP) with mitral annular disjunction (MAD) is an increasingly recognized arrhythmogenic phenotype in which focal myocardial fibrosis of the basal inferolateral wall serves as a substrate for ventricular arrhythmia and a target for ...
