A simple proof of monotonicity for remainder of Stirling's formula
Yuling Xue, Songbai Guo
The monotonicity properties of remainder of Stirling's formula for the gamma function are simply obtained by using the integral transforms with series.

Chuanqing Xu, Kedeng Cheng, Yu Wang +4
Tuberculosis (TB) is an infectious disease transmitted through the respiratory system. China is one of the countries with a high burden of TB. Since 2004, an average of more than 8…
Global stability of a time-delayed malaria model with standard incidence rate
Songbai Guo, Min He, Jing-An Cui
A four-dimensional delay differential equations (DDEs) model of malaria with standard incidence rate is proposed. By utilizing the limiting system of the model and Lyapunov direct…
