Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Optimal distribution of vehicular traffic flow with Dijkstra’s algorithm and Markov chains

African Scientific Reports
The optimization of traffic distribution is a critical problem in transportation networks, where efficient routing can reduce congestion, minimize travel time, and improve overall traffic flow.

Evidence of Free‐Bound Transitions in Warm Dense Matter and Their Impact on Equation‐of‐State Measurements

Contributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is now routinely created and probed in laboratories around the world, providing unprecedented insights into conditions achieved in stellar atmospheres, planetary interiors, and inertial confinement fusion experiments.

A modified algorithm of 'forward-backward' solving the identification of automata Markov models

Учёные записки Казанского университета: Серия Физико-математические науки, 2018
The paper is devoted to solving the problem of identifying discrete stochastic processes generated on the basis of automata Markov models. This problem is relevant because of the need to increase the efficiency of automata Markov models recognition.

Symmetric Markov Chains

The Annals of Probability, 1974
W. Feller's decomposition into a road map and speed measure are adapted to symmetric Markov chains with instantaneous states. The road map is a family of matrices defined by time changing the process with measures concentrated on finite sets.

Synergistic mechanisms foster declines in native fish community stability following the introduction of non‐native species

Ecography, EarlyView.
Non‐native species introductions profoundly alter freshwater communities, yet the mechanisms by which non‐native fishes affect native community stability remain unclear. Using a multi‐decadal dataset on fish community composition and abundance collected across France, we quantified native community stability and decomposed this metric into its main ...

A point on discrete versus continuous state-space Markov chains

Dependence Modeling
This article investigates the effects of discrete marginal distributions on copula-based Markov chains. We establish results on mixing properties and parameter estimation for a copula-based Markov chain model with Bernoulli(pp) marginal distributions ...

Modified Engel Algorithm and Applications in Absorbing/Non-Absorbing Markov Chains and Monopoly Game

Mathematical and Computational Applications
The Engel algorithm was created to solve chip-firing games and can be used to find the stationary distribution for absorbing Markov chains. Kaushal et al.

On markov chains and intuitionism

Indagationes Mathematicae (Proceedings), 1961
The paper contains an intuitionistic treatment of the theory of Markov chains with an enumerable state space. The theory is developed along the same lines as in the book of \textit{K. L. Chung} ``Markov chains with stationary transition probabilities''. Berlin etc.: Springer-Verlag (1960; Zbl 0092.34304).

Euromaidan and Ukrainian Subjective Well‐Being

European Journal of Social Psychology, EarlyView.
ABSTRACT The 2013–2014 Euromaidan in Ukraine was the largest series of pro‐European protests in history. Peaceful civilian protests were met with state violence, resulting in widespread civil unrest, over 100 deaths, and nearly 2000 injuries. The Russo‐Ukrainian War broke out shortly after. We examined the immediate and long‐term changes in Ukrainians’
