Systems Research and Behavioral Science, EarlyView.ABSTRACT This article investigates the characterization of cascading phenomena within sociotechnical systems through a systematic review and the development of a conceptual modelling framework. Cascading phenomena, often described using terms such as ripple effect, domino effect, cascading failure, risk propagation and cascading effect, capture the far‐

, 2015 Note that the terms ‘syncope’ and ‘loss of consciousness’ are not interchangeable as loss of consciousness can be due to either syncopal or non-syncopal causes. Syncope is a form of loss of consciousness in which hypoperfusion of the brain is the cause (from the Greek syn (together) and kopein (to cut), referring to the fact that the blood flow that ...

CoRRThis study explores the integration of Blackout Diffusion into the DIFUSCO framework for combinatorial optimization, specifically targeting the Traveling Salesman Problem (TSP). Inspired by the success of discrete-time diffusion models (D3PM) in maintaining structural integrity, we extend the paradigm to a continuous-time framework, leveraging the ...
