Li-Wei Liu et al.
The state-space representation is an alternative description of a dynamical system to the input-output representation in the systems theory. In this paper, we used the state-space representation to study the mechanical behavior of the tricu...

In the present study, the mechanical behavior of tricuspid valve (TV) chordae tendineae tissue is investigated experimentally and theoretically. A series of uniaxial mechanical testing experiments of the TV chordae tendineae is conducted an...
Using ultrasonic attenuation in cortical bone to infer distributions on pore size [0.03%]
利用皮质骨中超声衰减来推测孔隙大小的分布情况
R D White,A Alexanderian,O Yousefian et al.
R D White et al.
In this work we infer the underlying distribution on pore radius in human cortical bone samples using ultrasonic attenuation data. We first discuss how to formulate polydisperse attenuation models using a probabilistic approach and the Wate...
A Stochastic Mobility-Driven Spatially Explicit SEIQRD covid-19 Model with VOCs, Seasonality, and Vaccines [0.03%]
一种基于随机移动、具有关注变异毒株、季节性影响和疫苗的SEIQRD COVID-19空间显式模型
Tijs W Alleman,Michiel Rollier,Jenna Vergeynst et al.
Tijs W Alleman et al.
In this work, we extend our previously developed compartmental SEIQRD model for sars-cov-2 in Belgium. We introduce sars-cov-2 variants of concern, vaccines, and seasonality in our model, as their addition has proven necessary for modelling...
Stationary flow driven by non-sinusoidal time-periodic pressure gradients in wavy-walled channels [0.03%]
由非正弦时间周期压差驱动的波纹壁面管道内的驻留流动
J Alaminos-Quesada,C Gutiérrez-Montes,W Coenen et al.
J Alaminos-Quesada et al.
The classical problem of secondary flow driven by a sinusoidally varying pressure gradient is extended here to address periodic pressure gradients of complex waveform, which are present in many oscillatory physiological flows. A slender two...
Individual preferences, government policy, and COVID-19: A game-theoretic epidemiological analysis [0.03%]
个体偏好、政府政策与新冠肺炎：流行病学博弈论分析
Yuxun Zhou,Mohammad Mafizur Rahman,Rasheda Khanam et al.
Yuxun Zhou et al.
Purpose: The ongoing COVID-19 pandemic imposes serious short-term and long-term health costs on populations. Restrictive government policy measures decrease the risks of infection, but produce similarly serious social, me...
Disentangling the role of virus infectiousness and awareness-based human behavior during the early phase of the COVID-19 pandemic in the European Union [0.03%]
在2019冠状病毒病大流行初期解缠欧盟区域内病毒传播力与人类行为的角色关系
Marcos A Capistrán,Juan-Antonio Infante,Ángel M Ramos et al.
Marcos A Capistrán et al.
In this work, we manage to disentangle the role of virus infectiousness and awareness-based human behavior in the COVID-19 pandemic. Using Bayesian inference, we quantify the uncertainty of a state-space model whose propagator is based on a...
Optimal evaluation of re-opening policies for COVID-19 through the use of metaheuristic schemes [0.03%]
利用元启发式算法评估COVID-19重新开放政策的最优解
Erik Cuevas,Alma Rodríguez,Marco Perez et al.
Erik Cuevas et al.
A new contagious disease or unidentified COVID-19 variants could provoke a new collapse in the global economy. Under such conditions, companies, factories, and organizations must adopt reopening policies that allow their operations to reduc...

The high morbidity of acute respiratory infections constitutes a crucial global health burden. In particular, for SARS-CoV-2, non-pharmaceutical intervention geared to enforce social distancing policies, vaccination, and treatments will rem...

A common basis to address the dynamics of directly transmitted infectious diseases, such as COVID-19, are compartmental (or SIR) models. SIR models typically assume homogenous population mixing, a simplification that is convenient but unrea...
