Some limit theorems for ratios of transition probabilities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
In this paper, infinite dimensional forward convergent stochastic chains have been considered in the framework of [1]. The main result of this paper deals with the observation that the total flow of probability from the C-states to the T-states is very ...

Improving the Estimation of Markov Transition Probabilities Using Mechanistic-Empirical Models

open access: yesFrontiers in Built Environment, 2017
In many current state-of-the-art bridge management systems, Markov models are used for both the prediction of deterioration and the determination of optimal intervention strategies.

Atomic Data for Astrophysically Important Spectral Lines of Singly Ionized Nitrogen

open access: yesThe Astrophysical Journal
Nitrogen lines are widely observed in astrophysical spectra and provide important diagnostics for plasma properties. In this work, we present extended calculations for accurate energy levels, electric dipole radiative transition parameters, and lifetimes

Scale-invariant transition probabilities in free word association trajectories

open access: yesFrontiers in Integrative Neuroscience, 2009
Free-word association has been used as a vehicle to understand the organization of human thoughts. The original studies relied mainly on qualitative assertions, yielding the widely intuitive notion that trajectories of word associations are structured ...

A note on computing average state occupation times

open access: yesDemographic Research, 2014
Objective: This review discusses how biometricians would probably compute or estimate expected waiting times, if they had the data. Methods: Our framework is a time-inhomogeneous Markov multistate model, where all transition hazards are allowed to be ...

Methodology for transition probabilities determination in a Markov decision processes model for quality-accuracy management [PDF]

open access: yesJournal of Engineering Management and Competitiveness, 2014
The main goal of the presented research is to define a methodology for determination of the transition probabilities in a Markov Decision Process on the example of optimization of the quality accuracy through optimization of its main measure (percent of ...

Markov chains as a proxy for the predictive memory representations underlying mismatch negativity

open access: yesFrontiers in Human Neuroscience, 2023
Events not conforming to a regularity inherent to a sequence of events elicit prediction error signals of the brain such as the Mismatch Negativity (MMN) and impair behavioral task performance.

Calculated oscillator strengths and transition probabilities of singly ionised nickel (Ni II)

open access: yesAstronomy & Astrophysics
Aims. This work reports calculated transition probabilities for spectral lines of singly ionised nickel (Ni II) incorporating newly determined experimental energy levels, addressing critical gaps in atomic data required for astrophysical spectroscopy and

Basic parametric analysis for a multi-state model in hospital epidemiology

open access: yesBMC Medical Research Methodology, 2017
Background The extended illness-death model is a useful tool to study the risks and consequences of hospital-acquired infections (HAIs). The statistical quantities of interest are the transition-specific hazard rates and the transition probabilities as ...
