Channel networks are key to coastal wetland functioning and resilience under climate
change. Vegetation affects sediment and hydrodynamics in many different ways, which calls …

We study the problem of a policymaker who aims at taming the spread of an epidemic while
minimizing its associated social costs. The main feature of our model lies in the fact that the …

In this paper a Feynman-type path integral control approach is used for a recursive
formulation of a health objective function subject to a fatigue dynamics, a forward-looking …

In this work, we provide a general mathematical formalism to study the optimal control of an
epidemic, such as the COVID-19 pandemic, via incentives to lockdown and testing. In …

With the recent trend in the spread of coronavirus disease 2019 (Covid-19), there is a need
for an accurate approximate analytical solution from which several intrinsic features of …

This paper studies a discrete-time time-varying multi-layer networked SIWS (susceptible-
infected-water-susceptible) model with multiple resources under both single-virus and …

The aim of this article is to determine the optimal intensity of lock-down measures and
vaccination rates to control the spread of coronavirus disease 2019. The study uses a …

Objectives The COVID-19 pandemic placed significant strain on many health systems and
economies. Mitigation policies decreased health impacts but had major macroeconomic …

The stability of the economy of any country is primarily determined by the totality of
macroeconomic indicators that describe the current economic state. This article provides a …

Lockdown procedures have been proven successful in mitigating the spread of the viruses
in this COVID-19 pandemic, but they also have devastating impact on the economy. We use …
