Macroscopic fluctuation theory and current fluctuations in active lattice gases
SciPost Physics, 2023 We study the current large deviations for a lattice model of interacting active particles displaying a motility-induced phase separation (MIPS). To do this, we first derive the exact fluctuating hydrodynamics of the model in the large system limit.

Transition between two regimes describing internal fluctuation of DNA in a nanochannel. [PDF]
PLoS ONE, 2011 We measure the thermal fluctuation of the internal segments of a piece of DNA confined in a nanochannel about 50-100 nm wide. This local thermodynamic property is key to accurate measurement of distances in genomic analysis.

Field theory of fluctuations in glasses [PDF]
The European Physical Journal E, 2011 We develop a field-theoretical description of dynamical heterogeneities and fluctuations in supercooled liquids close to the (avoided) MCT singularity. Using quasi-equilibrium arguments we eliminate time from the description and we completely characterize fluctuations in the beta regime.

Fluctuation Theory for Upwards Skip-Free Lévy Chains
Risks, 2018 A fluctuation theory and, in particular, a theory of scale functions is developed for upwards skip-free Lévy chains, i.e., for right-continuous random walks embedded into continuous time as compound Poisson processes.

Semiclassical gravity theory and quantum fluctuations [PDF]
Physical Review D, 1993 We discuss the limits of validity of the semiclassical theory of gravity in which a classical metric is coupled to the expectation value of the stress tensor. It is argued that this theory is a good approximation only when the fluctuations in the stress tensor are small. We calculate a dimensionless measure of these fluctuations for a scalar field on a

IEEE Access, 2020 To improve the prediction accuracy of the wave propagation velocity of high-speed railway catenary, a method for identifying the fluctuation velocity of catenary (FVC) considering the influence of the accessory parts of catenary (APC) is proposed.

Dependent Competing Failure Processes in Reliability Systems
EntropyThis paper deals with a reliability system hit by three types of shocks ranked as harmless, critical, or extreme, depending on their magnitudes, being below H1, between H1 and H2, and above H2, respectively.

Evaluation Method of Wind Power Consumption Capacity Based on Multi-Fractal Theory
Frontiers in Energy Research, 2021 An analysis model of wind power consumption capacity is established with the multi-fractal theory. Firstly, the fluctuation characteristics of wind power are described through multi-fractal parameters, and the correlation between wind power fluctuation ...

On the Balance between Emigration and Immigration as Random Walks on Non-Negative Integers
MathematicsLife is on a razor’s edge resulting from the random competitive forces of birth and death. We illustrate this aphorism in the context of three Markov chain population models where systematic random immigration events promoting growth are simultaneously ...
