Summary: This article investigates the time at which a one-dimensional stationary time series reaches its global maximum and computes the probability density function of this time for various processes. It is found that for equilibrium processes, the distribution of this time is always symmetric around the midpoint of the time interval. The article also shows that for a diffusive particle in a confining potential, the scaled distribution of this time becomes universal at late times.

Summary: Relative permeability is derived from conservation of energy and used to model fluid flow through porous materials. The study finds dynamic connectivity and explores the distribution of energy fluctuations during steady-state flow. It demonstrates the effectiveness of the conventional relative permeability relationship in simulating energy dissipation in systems with complex pore-scale dynamics.

Summary: This article discusses the non-Gaussian distributions observed in stellar parameter distributions and proposes a formalism of superstatistics to explain these distributions. The distributions are compared with observational data and their moments are computed. The article also addresses the thermalization effects of these distributions on massive objects and highlights how superstatistics can resolve ambiguities and offer possibilities for fitting observational data.

Summary: This article introduces an exponential analytic stationary subspace analysis (EASSA) algorithm to develop an adaptive strategy for nonstationary process monitoring. By accurately estimating stationary sources and developing a monitoring strategy based on them, reliable monitoring of nonstationary processes can be achieved.

Summary: This study develops and investigates a stochastic HLIV model with viral production and Ornstein-Uhlenbeck process to examine the effects of stochastic perturbations on the pathogenesis process of HIV/AIDS. The findings indicate that the interference of random factors greatly influences the persistence of the disease and the clearance of viruses. Numerical simulations validate the effectiveness of the theoretical results.

Summary: This study discusses the extremization of entropy production in fluidic networks to mathematically formalize thermal engineering transfer phenomena using non-equilibrium thermodynamics. A variational formulation of two-phase flow distribution in fluidic junctions is developed, showing that the flow is distributed to maximize or minimize the entropy generation rate. Various factors affecting flow distribution and phase separation are explored, supporting the use of non-equilibrium thermodynamics for general mathematical formulations of thermal engineering transfer phenomena.

Summary: The improved polyester fabric printing ink enhances ink diffusion on the fabric surface by regulating intermolecular forces and ink microstructure. The LF-NMR test reveals the characteristics of main reagent solutions and ink, showing a correlation between ink viscosity and transverse relaxation time. This innovative ink has the potential to achieve green printing with environmental protection, high efficiency, and low energy consumption.

Summary: This paper investigates the entropy production of diffusion processes at non-equilibrium steady-state, and examines the condition that the time-reversal of the diffusion remains a diffusion. The study shows that the measures of the forward and time-reversed path space are mutually equivalent when the time-irreversible part of the drift is in the range of the volatility matrix, and evaluates the entropy production.

Summary: Long-term memory behavior is an important phenomenon in time series analysis. The excess entropy approach is used to classify long-term and short-term memory in stationary time series. Simulation results demonstrate the effectiveness of the approach on various stochastic sequences. The approach has advantages over traditional methods as it is invariant under instantaneous one-to-one transformation and has weak moment conditions.

Summary: Traditionally, the diffusion rates of point defects are believed to be mainly influenced by energy barriers. However, in disordered environments, the entropic variations between local minima and activated states become increasingly important. The unexpectedly slower defect diffusion observed in high entropy alloys has prompted researchers to revisit the role of pre-factors.

Summary: We investigate the nonequilibrium dynamics of a Luttinger liquid following a simultaneous quantum quench of the interaction and dissipative quench to the environment using the Lindblad equation. When the couplings to the environment satisfy detailed balance, the system is destined to thermalize, and we track this process using bosonization. The thermodynamic entropy of the system, which also encodes information about the entanglement with the environment, either exhibits extrema or monotonically grows before reaching its thermal value in a universal manner. The spatiotemporal phase diagram of the single-particle density matrix shows interesting features, including thermal, prethermal, and dissipation-enhanced sudden quench Luttinger liquid behavior, as well as dissipation-enhanced Fermi liquid response.

Summary: Industrial processes often exhibit nonstationary behavior, making it difficult to distinguish faults from changes in statistical characteristics. Cointegration analysis provides long-term equilibrium relationships but has nonorthogonal components and high computational costs. In contrast, orthogonal stationary component analysis offers a more effective way to select orthogonal components for nonstationary cases.

Summary: This paper investigates the dynamics of charged particles in spatially inhomogeneous time-stationary Beltrami magnetic fields, analyzing the chaotic behavior and transport properties of particles in such fields. It also compares the behavior of charged particles in time-periodic Beltrami magnetic fields to those in time-stationary fields, noting differences in anomalous diffusion.

Summary: High-entropy ceramics, containing five or more cations, have attracted significant attention recently for their superior properties in various structural and functional applications. Efforts have been made to increase entropy, minimize Gibbs free energy and achieve stable single-phase high-entropy ceramics. These materials have potential for future applications in fields such as oxides, nitrides, carbides, borides, and hydrides.

Summary: This study introduces a finite memory ansatz that approximates or recovers the true process while ensuring errors are bounded by the strength of the non-Markovian memory. The introduced memory strength is dependent on the probing method, with the recovery error constrained by the smallest memory strength across all possible methods. This allows for an unambiguous and efficient description of non-Markovian phenomena, with implications for compression and recovery techniques essential for near-term technologies.

Summary: Recent studies have shown that one-dimensional antiferromagnetic spin models with frustrated boundary conditions may exhibit peculiar behavior, but the introduction of frustrated boundary conditions does not alter the topological order phases analyzed in the models.

Summary: This work demonstrates that the presence of an odd or even number of elements in antiferromagnetic quantum spin rings can lead to qualitatively and quantitatively different outcomes in non-equilibrium experiments. The observed differences in the low energy spectra between frustrated and non-frustrated chains can be used in quantum thermodynamics protocols.
