• INVESTIGATING POSITIVE PERIODIC SOLUTIONS IN SUPERLINEAR FIRST-ORDER DIFFERENTIAL SYSTEMS THROUGH GLOBAL BIFURCATION THEORY

  Cheng Z, Lv L, Liu J

  This paper investigates the superlinear first-order differential systems of the form u′(t)+a(t)u(t)=λb(t)f(v(t−τ(t))), t R, v′(t)+a(t)v(t)=λb(t)g(u(t−τ(t))), t R, where λ is a parameter and a, b, τ, f, and g satisfy certain assumptions. The aim of this study is to explore the existence of

• COMBINING DATA ASSIMILATION AND THE SIR INFECTION EQUATION FOR BETTER UNDERSTANDING OF COVID-19

  G. Kitagawa

  The outbreak of the new coronavirus pandemic (COVID-19) has created a global health crisis, and a significant challenge to mitigate its spread and impact on global communities. The SIR equation has been widely used as a theoretical model to simulate the course of an infection, however, its
