Dynamics of Dengue epidemics using optimal control [PDF]
Math. Comput. Modelling 52 (2010), no. 9-10, 1667--1673, 2010 We present an application of optimal control theory to Dengue epidemics. This epidemiologic disease is an important theme in tropical countries due to the growing number of infected individuals. The dynamic model is described by a set of nonlinear ordinary differential equations, that depend on the dynamic of the Dengue mosquito, the number of infected

Estimating the impact of non-pharmaceutical interventions and vaccination on the progress of the COVID-19 epidemic in Mexico: a mathematical approach [PDF]
arXiv, 2021 Non-pharmaceutical interventions have been critical in the fight against the COVID-19 pandemic. However, these sanitary measures have been partially lifted due to socioeconomic factors causing a worrisome rebound of the epidemic in several countries. In this work, we assess the effectiveness of the mitigation implemented to constrain the spread of SARS-

Beyond COVID-19 Pandemic: Topology-aware optimisation of vaccination strategy for minimising virus spreading [PDF]
arXiv, 2022 The mitigation of an infectious disease spreading has recently gained considerable attention from the research community. It may be obtained by adopting sanitary measurements social rules, together with an extensive vaccination campaign. Vaccination is currently the primary way for mitigating the Coronavirus Disease (COVID-19) outbreak without severe ...

Urban water networks as an alternative source for district heating and emergency heat-wave cooling [PDF]
Energy, Volume 145, 15 February 2018, Pages 79-87, 2018 Urban water networks can contribute to the energy transition of cities by serving as alternatives sources for heating and cooling. Indeed, the thermal energy potential of the urban water cycle is considerable. Paris is taken as an example to present an assessment of the field performance of a district-scale waste water heat recovery system and to ...

Preventing diseases in an urban scale
E3S Web of Conferences, 2018 A perfect setup to prevent epidemics is currently in affect throughout the world. Sanitary engineering, though not directly, is largely responsible for the annihilation of many diseases that used to be very problematic, such as typhus or cholera. However,

Are veterinary drug maximum residue limits protectionist? International evidence
Applied Economic Perspectives and Policy, EarlyView.Abstract We analyze the distribution of maximum residue limits (MRLs) on veterinary drugs used in animal production and aquaculture in a global context of food consumption and trade. We compare MRLs by drug‐product pairs for a large set of countries, commodities, and drugs.
