Quantum channels describe subsystem or open-system evolution. Using the classical Koopman operator that evolves functions on phase space, four classical Koopman channels are identified as analogs of the four possible quantum channels in a b...
Understanding pesticide-induced tipping in plant-pollinator networks across geographical scales: Prioritizing richness and modularity over nestedness [0.03%]
理解植物-传粉者网络中由农药诱导的临界转换：重视丰富度和模块化胜过嵌套性

Mutually beneficial interactions between plants and pollinators are crucial for biodiversity, ecosystem stability, and crop production. A threat to a mutualistic network is the occurrence of a tipping point at which the species abundances c...

We address the counting of level crossings for the generalized Brownian motion in which the motion of a Brownian particle (unbound as well as linearly bound) is governed by an integrodifferential stochastic equation with a memory dissipatio...

Generative diffusion models apply the concept of Langevin dynamics in physics to machine learning, attracting a lot of interest from engineering, statistics, and physics, but a complete picture of inherent mechanisms is still lacking. In th...

Synchronization analysis of real-world systems is essential across numerous fields, including physics, chemistry, and life sciences. Generally, the governing equations of these systems are unknown, and thus, the phase is calculated from mea...
Heat capacity and relaxation dynamics of glassy films: A lattice model study [0.03%]
玻璃薄膜的比热和弛豫动力学：晶格模型研究

Qiang Zhai et al.
We study the calorimetric properties and structural relaxation of glassy films using a distinguishable particle lattice model (DPLM). We determine the glass transition temperature versus film thickness from the heat capacity during heating ...
Noise-induced transitions from contractile to extensile active stress in isotropic fluids [0.03%]
噪声引起的各向同性流体从收缩到伸展的活性应力转换

Tissues of living cells are a prime example of active fluids. There is experimental evidence that tissues generate extensile active stress even though their constituting cells are contractile. Fluctuating forces that could result from cell-...
Effects of radial conductivity variation on the Ponomarenko dynamo [0.03%]

We study the effects of conductivity variation on the Ponomarenko dynamo. Taking monotonically increasing, decreasing and sinusoidally varying radial profiles, we study the kinematic dynamo problem. The threshold of the dynamo, given by the...

Disordered systems theory provides powerful tools to analyze the generic behaviors of high-dimensional systems, such as species-rich ecological communities or neural networks. By assuming randomness in their interactions, universality ensur...
Existence and stability of equilibria in infectious disease dynamics with behavioral feedback [0.03%]

Tyrus Berry et al.
Mathematical models have provided a general framework for understanding the dynamics and control of infectious disease. Many compartmental models are limited in that they do not account for the range of behavioral feedbacks that have been o...
