Cascading Failure Propagation Simulation in Integrated Electricity and Natural Gas Systems

Journal of Modern Power Systems and Clean Energy, 2020
The sharp increase in the total installed capacity of natural gas generators has intensified the dynamic interaction between the electricity and natural gas systems, which could induce cascading failure propagation across the two systems that deserves ...

A model for cascading failures with the probability of failure described as a logistic function

Scientific Reports, 2022
In most cascading failure models in networks, overloaded nodes are assumed to fail and are removed from the network. However, this is not always the case due to network mitigation measures. Considering the effects of these mitigating measures, we propose

Robust network routing under cascading failures [PDF]

53rd IEEE Conference on Decision and Control, 2014
We propose a dynamical model for cascading failures in single-commodity network flows. In the proposed model, the network state consists of flows and activation status of the links. Network dynamics is determined by a, possibly state-dependent and adversarial, disturbance process that reduces flow capacity on the links, and routing policies at the ...

A Network Perspective On Assessing System Architectures:Robustness to Cascading Failure [PDF]

, 2020
Despite a wealth of system architecture frameworks and methodologies available, approaches to evaluate the robustness and resiliency of architectures for complex systems or systems of systems are few in number.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

The impact of a network split on cascading failure processes [PDF]

, 2017
Cascading failure models are typically used to capture the phenomenon where failures possibly trigger further failures in succession, causing knock-on effects.

Research on Chaotic Characteristics of Cascade Failure in Rail Transit Networks considering Nonlinear Load Fluctuations

Journal of Advanced Transportation
The stable and efficient operation of rail transit networks (RTNs) is critical for the integrated development of metropolitan areas. However, numerous studies have indicated that RTNs are prone to large-scale cascading failures when subjected to ...

Exploring cascading failure in directed weighted small-world network: An adaptive SIRS-F mechanism

International Journal of Electrical Power & Energy Systems
Cascading failures in complex networks is a significant threat to system reliability and robustness, influencing various aspects of daily life. The small-world characteristics within complex networks contribute to increased complexity, making it ...

Model for cascading failures in functional networks: application to epileptic patients with generalized tonic-clonic seizures [PDF]

Journal of Integrative Neuroscience, 2019
The dynamic process of epilepsy is modeled as a cascading failure model in functional networks derived from graph theory. The aim is to test whether cascading failure identified from functional magnetic resonance imaging data could simulate epileptic ...

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.
