On the Dynamical Complexity of a Seasonally Forced Discrete SIR Epidemic Model with a Constant Vaccination Strategy by Jalil Rashidinia, Mehri Sajjadian, Jorge Duarte, Cristina Januário, Nuno Martins

“…Studying the evolution of the dynamical variables, a family of unimodal-type iterated maps with a striking biological meaning is detected among those dynamical regimes of the densities of the susceptibles. Using the theory of symbolic dynamics, these iterated maps are characterized based on the computation of an important numerical invariant, the topological entropy. …”

Statistical Damage Constitutive Model for Cemented Sand considering the Residual Strength and Initial Compaction Phase by Cai Tan, Ming-dao Yuan, Yong-sheng Shi, Bing-sheng Zhou, Hao Li

“…Based on continuum damage mechanics and the assumption of volume invariance, a damage constitutive model of cemented sand under triaxial stress was established while considering residual strength. Statistical theory was then introduced into this model. Assuming that the microunit strength of cemented sand obeys a Weibull random distribution, an expression of microunit strength based on the Mohr–Coulomb criterion was derived. …”

A COMPARATIVE ANALYSIS BETWEEN WESTERN BALKAN COUNTRIES AND SELECTED OECD COUNTRIES (2010 - 2019) OF THE EFFECT OF UNEMPLOYMENT ON NON-PERFORMING LOAN by Ercan Özen, Ajshe Komoni, Fisnik Morina, Simon Grıma, İbish Mazreku

“…To carry out this study, panel data and quantitative econometric models have been applied, specifically Linear Regression, Random Effect, Fixed Effect, Huasman - Taylor Regression and Generalized Estimating Equations (GEE Model) on secondary data from official reports of the World Bank, Organization for Economic Cooperation and Development, during the period from 2010 to 2019. Based on economic theory and our findings, we can say that the relationship between the unemployment rate and non-performing loans is directly proportional: an increase in the unemployment rate will lead to an increase in the non-performing loan rate. …”

A Solution of Subgrade Modulus for Response Displacement Method of Circular Underground Structures by Wei Wang, Kun Feng, Yunchao Wang, Chuan He, Guojin Zhu, Yu Ning, Lixiang Zhao

“…First, the analytical solutions of subgrade modulus for ground deformation modes described by the Fourier series are derived based on the theory of elasticity. The ratio of the radial displacement to tangential displacement is introduced to create a link between the radial and tangential subgrade modulus. …”
