Infrared precursor of pre-cracked coal failure based on critical slowing down

open access: yesGeomatics, Natural Hazards & Risk, 2022
In order to study the precursor information of infrared radiation temperature of coal containing macro-cracks during load bearing damage, infrared monitoring tests of coal instability damage under different crack inclination angles are designed. Based on

Critical slowing down of semiarid vegetation resilience is amplified by intensifying heatwaves [PDF]

open access: yesNature Communications
Critical slowing down is commonly used as an early-warning signature of declining ecosystem resilience. While widespread greening has been documented, vegetation resilience in semiarid regions has received limited attention, and how climate extremes ...

Lack of Critical Slowing Down Suggests that Financial Meltdowns Are Not Critical Transitions, yet Rising Variability Could Signal Systemic Risk. [PDF]

open access: yesPLoS ONE, 2016
Complex systems inspired analysis suggests a hypothesis that financial meltdowns are abrupt critical transitions that occur when the system reaches a tipping point. Theoretical and empirical studies on climatic and ecological dynamical systems have shown

Modeling and Detection of Critical Slowing Down in Epileptic Dynamics [PDF]

open access: yes2025 European Control Conference (ECC)
Epilepsy is a common neurological disorder characterized by abrupt seizures. Although seizures may appear random, they are often preceded by early warning signs in neural signals, notably, critical slowing down, a phenomenon in which the system's recovery rate from perturbations declines when it approaches a critical point.

Precursory Indicator for Mode I Fracture in Brittle Rock through Critical Slowing Down Analysis

open access: yesShock and Vibration, 2020
The abrupt rock-related hazards, such as landslide, rock burst, and collapse, seriously threaten the safety and service life of engineering works. Precursory information on critical transitions preceding sudden fracture is of great significance in rock ...

Critical Slowing Down Exponents of Mode Coupling Theory [PDF]

open access: yesPhysical Review Letters, 2012
A method is provided to compute the exponent parameter λ yielding the dynamic exponents of critical slowing down in mode coupling theory. It is independent from the dynamic approach and based on the formulation of an effective static field theory. Expressions of λ in terms of third order coefficients of the action expansion or, equivalently, in terms ...

Experimental study on electric potential critical slowing down characteristics before unstable failure of roof rocks

open access: yesGong-kuang zidonghua, 2018
In order to study critical slowing down characteristics of surface electric potential (EP) before unstable failure of roof rocks, loading failure experiment of rock specimens was carried out, the surface EP signal of rocks was collected in loading ...

Early Warning Signals in Ecological Time-Series [PDF]

open access: yesEntropy
Ecosystems can undergo abrupt, often irreversible transitions between alternative states—phenomena termed critical transitions or regime shifts—with profound consequences for biodiversity, ecosystem services, and human well-being.

Critical slowing down in biochemical networks with feedback. [PDF]

open access: yesPhys Rev E, 2019
Near a bifurcation point, the response time of a system is expected to diverge due to the phenomenon of critical slowing down. We investigate critical slowing down in well-mixed stochastic models of biochemical feedback by exploiting a mapping to the mean-field Ising universality class.
