DBGDGM: Dynamic Brain Graph Deep Generative Model [PDF]
arXiv, 2023 Graphs are a natural representation of brain activity derived from functional magnetic imaging (fMRI) data. It is well known that clusters of anatomical brain regions, known as functional connectivity networks (FCNs), encode temporal relationships which can serve as useful biomarkers for understanding brain function and dysfunction.

Hemodynamics of a Bileaflet Mechanical Heart Valve with Different Levels of Dysfunction [PDF]
Volume 2 Issue 5 - 2017, 2017 Heart disease is one of leading causes of mortality worldwide. Healthy heart valves are key for proper heart function. When these valves dysfunction, a replacement is often necessary in severe cases. The current study presents an investigation of the pulsatile blood flow through a bileaflet mechanical heart valve (BMHV) where one leaflet is healthy and

Temporary neonatal atrial pacing through the umbilical venous route: A novel technique
Annals of Pediatric Cardiology, 2011 Atrial pacing in the neonate is rarely done due to constraints of equipment, technical knowhow, and risk of complications. We describe a novel method of atrial pacing in the new born using equipment readily available in any intensive care unit.

Instantaneous and limiting behavior of an n-node blockchain under cyber attacks from a single hacker [PDF]
arXiv, 2022 We investigate the instantaneous and limiting behavior of an n-node blockchain which is under continuous monitoring of the IT department of a company but faces non-stop cyber attacks from a single hacker. The blockchain is functional as far as no data stored on it has been changed, deleted, or locked.

If players are sparse social dilemmas are too: Importance of percolation for evolution of cooperation [PDF]
Sci. Rep. 2 (2012) 369, 2012 Spatial reciprocity is a well known tour de force of cooperation promotion. A thorough understanding of the effects of different population densities is therefore crucial. Here we study the evolution of cooperation in social dilemmas on different interaction graphs with a certain fraction of vacant nodes.
