Since the emergence of the first cases in Wuhan, China, the novel coronavirus (2019-nCoV)
infection has been quickly spreading out to other provinces and neighboring countries. …

The basic reproduction number of an infectious agent is the average number of infections
one case can generate over the course of the infectious period, in a naïve, uninfected …

In most models of population dynamics, increases in population due to birth are assumed to
be time-independent, but many species reproduce only during a single period of the year. …

In order to control pests, a specific management strategy called the threshold policy is proposed,
which can be described by Filippov systems (or piecewise smooth systems). The aim of …

The novel Coronavirus (COVID-19) is spreading and has caused a large-scale infection in
China since December 2019. This has led to a significant impact on the lives and economy in …

Background Radio/chemotherapy and immune systems provide examples of hormesis, as
tumours can be stimulated (or reduced) at low radio/chemical or antibody doses but inhibited (…

Two impulsive models of integrated pest management (IPM) strategies are proposed, one
with fixed intervention times and the other with these unfixed. The first model allows natural …

The 2019 novel coronavirus disease (COVID-19) is running rampantly in China and is
swiftly spreading to other countries in the world, which causes a great concern on the global …
