Finite-time stability analysis and control of stochastic SIR epidemic model: A study of COVID-19.
Biomed Signal Process Control
September 2023
Finite-time stability analysis is a powerful tool for understanding the long-term behavior of epidemiological models and has been widely used to study the spread of infectious diseases such as COVID-19. In this paper, we present a finite-time stability analysis of a stochastic susceptible-infected-recovered (SIR) epidemic compartmental model with switching signals. The model includes a linear parameter variation (LPV) and switching system that represents the impact of external factors, such as changes in public health policies or seasonal variations, on the transmission rate of the disease.

- Nitrogen (N) is a crucial nutrient for plant growth and is the most commonly used fertilizer in agriculture, but only about 50% of applied N is effectively used by crops.
- Excess nitrogen is lost through processes like volatilization, runoff, leaching, and denitrification, which harms the environment and reduces farmers' returns.
- Improving Nitrogen Use Efficiency (NUE) through better management practices and technological advancements is essential for reducing environmental impacts and meeting agricultural demands sustainably.
Background: The COVID-19 pandemic has captured the mental health discussion worldwide. Examining countries' representation in this discussion could prove instrumental in identifying potential gaps in terms of ensuring a truly global conversation in times of global crisis.
Methods: We collected mental health and COVID-19-related journal articles published in PubMed in 2020.
