Log-Linear Model and Multistate Model to Assess the Rate of Fibrosis in Patients With NAFLD

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In this paper, the deleterious effects of obesity, type II diabetes, and insulin resistance, systolic and diastolic hypertension on the rate of progression of fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) are illustrated using a new

Impact analysis of external stimuli based on the emotional state transfer model

open access: yes工程科学学报, 2015
In order to study the effect of external stimulus duration on the emotional state transition of people,firstly,the Gross emotional regulation process and the finite state machine are used to describe the emotional state transition process.

Analysis of a Pre-Emptive Two-Priority Queuing System with Impatient Customers and Heterogeneous Servers

open access: yesMathematics, 2023
This paper presents a queuing system model that incorporates multiple priorities, multiple abandonments, and heterogeneous servers. Waiting for service easily leads to impatient behaviors.

State-Transition Matrix for Satellite Relative Motion in the Presence of Gravitational Perturbations

open access: yesJournal of Guidance Control and Dynamics, 2019
A state-transition matrix (STM) for the relative motion of artificial satellites is presented in this work that is valid in the presence of the gravitational spherical harmonic perturbations.

Markov-chain Modelling and Simulative Assessment of the Impact of Selected Tactical Behaviours in Modern Tennis

open access: yesInternational Journal of Racket Sports Science, 2023
Game behaviour in net games or other sports is often captured in the form of discrete performance indicators which represent frequencies or relative frequencies of key behavioural variables.

Control Strategy of Discrete Event Systems Modeled by Labeled Petri Nets Based on Transition Priority

open access: yesIEEE Access, 2023
This paper deals with the supervisory control problem of discrete event systems modeled with labeled Petri nets. A transition priority matrix is proposed to control the firing of controllable transitions to prevent the system from entering illegal states.

Stochastic Stabilization for Discrete-Time Markovian Jump Systems With Time-Varying Delay and Two Markov Chains Under Partly Known Transition Probabilities

open access: yesIEEE Access, 2021
This paper investigates the problem of state feedback controller design for discrete-time Markovian jump systems (MJSs) with time delay and two Markov chains under partly known transition probabilities. First, by constructing improved Lyapunov-Krasovskii

Unconventional topological mixed-state transition and critical phase induced by self-dual coherent errors [PDF]

open access: yesPhysical review B
A topological phase can undergo a phase transition driven by anyon condensation. A potential obstruction to such a mechanism could arise if there exists a symmetry between anyons that have non-trivial mutual statistics.
