Synchronization of Coupled Chaotic Dynamics on Networks
We review some recent work on the synchronization of coupled dynamical
systems on a variety of networks. When nodes show synchronized behaviour, two
interesting phenomena can be observed. First, there are some nodes of the
floating type that show intermittent behaviour between getting attached to some
clusters and evolving independently. Secondly, two different ways of cluster
formation can be identified, namely self-organized clusters which have mostly
intra-cluster couplings and driven clusters which have mostly inter-cluster
couplings.Comment: 15 pages, 3 figure
Waitlist Priority for Patients with Acute-on-Chronic Liver Failure: Not Just Horseplay
Acute on chronic liver failure (ACLF) is a syndrome of systemic inflammation and multiple organ system failures that is associated with a significantly high 28-day mortality ranging from 15-89%,(1) and which is increasing in prevalence in the United States and globally.(2) Although several definitions for ACLF exist, it is generally agreed upon that this condition yields greater non-transplant mortality than mere decompensated cirrhosis. The EASL-CLIF definition of ACLF categorizes patients according to the number of organ failures present, specifically as 1 organ failure (ACLF-1), 2 organ failures (ACLF-2) and 3 or more organ failures (ACLF-3).(1) Liver transplantation (LT) remains the only life-saving intervention in this population, especially among those with ACLF-3
