A new piecewise linear Chen system of fractional-order; Numerical approximation of stable attractors

In this paper we present a new version of Chen’s system — a piecewise linear Chen system of fractional-order. Via a sigmoid-like function, the discontinuous system is transformed into a continuous system. By numerical simulations, we reveal chaotic behaviors and also mulistability, i.e. the existence of small parameter windows where, for some fixed bifurcation parameter and depending on initial...

Understanding the 2019-novel Coronavirus (2019-nCoV) and Coronavirus Disease (COVID-19) Based on Available Evidence - A Review Study

Since December 2019, a new coronavirus, called the 2019-novel coronavirus (2019-nCoV), triggers pneumonia outbreak from Wuhan (Huanan seafood market) across China, which now poses major health threats to public health. The Corona Virus Disease-2019 (COVID-19) epidemic by 2019-nCoV is spreading worldwide, and by March 1, 2020, 67 countries, including Iran, have been affected. According to worldw...
