Transition times in the Landau-Zener model [PDF]

, 1998
This paper presents analytic formulas for various transition times in the Landau-Zener model. Considerable differences are found between the transition times in the diabatic and adiabatic bases, and between the jump time (the time for which the ...

Using informative prior based on expert opinion in Bayesian estimation of the transition probability matrix in Markov modelling—an example from the cost-effectiveness analysis of the treatment of patients with predominantly negative symptoms of schizophrenia with cariprazine

Cost Effectiveness and Resource Allocation, 2020
Background When patient health state transition evidence is missing from clinical literature, analysts are inclined to make simple assumptions to complete the transition matrices within a health economic model.

Atomic Transition Probabilities for Transitions of Si i and Si ii and the Silicon Abundances of Several Very Metal-poor Stars

The Astrophysical Journal Supplement Series, 2023
We report new measurements of branching fractions for 20 UV and blue lines in the spectrum of neutral silicon (Si i ) originating in the 3 s ^2 3 p 4 s ^3 P ^o _1,2 , ^1 P ^o _1 , and 3 s 3 p ^3 ^1 D ^o _1,2 upper levels. Transitions studied include both

Resonance enhancement of neutrino oscillations due to transition magnetic moments

, 2020
Studying neutrino propagation in static background of dense matter and electromagnetic field [1] we obtained that the resonance enhancement of neutrino oscillations due to transition magnetic moments is possible.

Lifetimes, transition probabilities, and level energies in Fe I [PDF]

, 1991
We use time-resolved laser-induced fluorescence to measure the lifetime of 186 Fe levels with energies between 25 900 and 60 758 cm . Measured emission branching fractions for these levels yield transition probabilities for 1174 transitions in the range ...

High-Energy Neutrino Flavor State Transition Probabilities

Applied Sciences
We analytically determine neutrino transitional probabilities and abundance ratios at various distances from the source of creation in several astrophysical contexts, including the Sun, supernovae and cosmic rays.

Experimental Determination of Electron Transition Probabilities in Elementary Electron-Phonon Scattering Processes Using Electron-Energy-Loss Spectroscopy: The Example of Graphite

, 2010
We have investigated coupling constants in elementary electron-phonon scattering processes on a graphite surface by the combined use of high-resolution electron-energy-loss spectroscopy (HREELS) and very low-energy electron diffraction (VLEED). HREELS is

Some limit theorems for ratios of transition probabilities

International 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

Frontiers 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.

Superstatistical random-matrix-theory approach to transition intensities in mixed systems

, 2006
We study the fluctuation properties of transition intensities applying a recently proposed generalization of the random matrix theory, which is based on Beck and Cohen's superstatistics.
