Bayesian on-line anticipation of critical transitions

open access: yesNew Journal of Physics, 2022
The design of reliable indicators to anticipate critical transitions in complex systems is an important task in order to detect imminent regime shifts and to intervene at an early stage to either prevent them or mitigate their consequences.

Identification of Critical Hidden Failure Line Based on State-failure-network

open access: yesJournal of Modern Power Systems and Clean Energy, 2022
The hidden failures generally exist in power systems and could give rise to cascading failures. Identification of hidden failures is challenging due to very low occurrence probabilities. This paper proposes a state-failure-network (SF-net-work) method to

Behavior of the Thermodynamic Properties of Binary Mixtures near the Critical Azeotrope

open access: yesEntropy, 2003
: In this work we investigate the critical line of binary azeotropic mixtures of acetone-n-pentane. We pinpoint the abnormal behavior of the critical density line as a function of the mole fraction of one of the component and show its influence on other ...

Critical span identification model with critical periods for dynamic thermal rating equipment arrangement [PDF]

open access: yesITM Web of Conferences, 2022
Compared with static thermal rating (STR), dynamic thermal rating (DTR) technology can explore the potential current-carrying capacity of overhead lines and bring considerable economic benefits. Considering that there are many spans of the overhead line,

Fate of the Critical Line and Chiral Transition in Finite-Temperature Lattice QCD with the Wilson Quark Action [PDF]

open access: yes, 1995
Finite-temperature phase structure of lattice QCD with the Wilson quark action is analyzed. We show that the critical line at finite temperatures, defined to be the line of vanishing pion screening mass, turns back toward strong coupling, forming a cusp ...

Acute kidney injury in postoperative shock: is hyperoncotic albumin administration an unrecognized resuscitation risk factor?

open access: yesPerioperative Medicine, 2018
Background The use of hyperoncotic albumin (HA) for shock resuscitation is controversial given concerns about its cost, effectiveness, and potential for nephrotoxicity.

Exploring autophagy in treating SARS-CoV-2 spike protein-related pathology

open access: yesEndocrine and Metabolic Science
Fasting, a practice with historical roots in various cultures, has recently garnered significant interest in the field of medicine. In this article, we delve into the mechanisms underlying fasting-induced autophagy and its therapeutic applications for ...

Interplay of quantum and classical fluctuations near quantum critical points

open access: yes, 2011
For a system near a quantum critical point (QCP), above its lower critical dimension $d_L$, there is in general a critical line of second order phase transitions that separates the broken symmetry phase at finite temperatures from the disordered phase ...

Slip Line Growth as a Critical Phenomenon

open access: yesPhysical Review Letters, 2009
We study the growth of slip line in a plastically deforming crystal by numerical simulation of a double-ended pile-up model with a dislocation source at one end, and an absorbing wall at the other end. In presence of defects, the pile-up undergoes a second order non-equilibrium phase transition as a function of stress, which can be characterized by ...
