Machine Learning Predictions of Transition Probabilities in Atomic Spectra

open access: yesAtoms, 2021
Forward modeling of optical spectra with absolute radiometric intensities requires knowledge of the individual transition probabilities for every transition in the spectrum.

Research on Disability Grading Based on ICF Functional Framework: Empirical Evidence From Zhejiang Province, China

open access: yesFrontiers in Public Health, 2021
Through assignment method, the total score of disability in multiple dimensions is obtained, and it is divided into five functional states—severe disability, partial disability, moderate disability, mild disability, and health—according to the score, and

A generalized scattering theory in quantum mechanics

open access: yesJournal of Physics Communications, 2023
In quantum mechanics textbooks, a single-particle scattering theory is introduced. In the present work, a generalized scattering theory is presented, which can be in principle applied to the scattering problems of arbitrary number of particle.

Computation of Characteristics of C IV Transitions

open access: yesEast European Journal of Physics, 2023
In this research, we computed transition probabilities, line strength, and oscillator strengths of more than 5000 transitions in C IV. Very few values of these spectroscopic characteristics were previously known and reported.

Tehran Stock Exchange dynamics in a Markov regime switching EGARCH-in-mean model [PDF]

open access: yesتحقیقات مالی, 2014
This paper examines regime shifts in TEDPIX return and volatility and the effects of positive and negative crude oil shocks and gold price fluctuations on stock market shifts behavior using Markov switching EGARCH model with Student’s t-distribution.

Maintaining the water consumption, in an urban system: A probabilistic approach is applied

open access: yesJournal of Water and Land Development, 2017
An urban system is influenced by many disruptions that may cause failures for it, in the end. In order to maintain continuity of its operations, analysis of its components operation becomes very necessary.

Network Analysis Using Markov Chain Applied to Wildlife Habitat Selection

open access: yesDiversity, 2022
In the present study, behavioral states for habitat selection are examined using a discrete-time Markov chain (DTMC) combined with a network model with wildlife movement data.

MDPs with setwise continuous transition probabilities [PDF]

open access: yesOperations Research Letters, 2021
This paper describes the structure of optimal policies for infinite-state Markov Decision Processes with setwise continuous transition probabilities. The action sets may be noncompact. The objective criteria are either the expected total discounted and undiscounted costs or average costs per unit time.
