1. Dynamic Systems with Fractional Derivatives Applied to Interagent Populations Problems
ABSTRACT The present work has as main objective to investigate the use of fractional calculus in the modeling of epidemic outbreaks of interacting populations. In particular, we propose a generalization of the SIR model with fractional derivatives to describe the dynamics of the COVID-19 epidemic outbreak in two cities with interacting populations. In specia

2. Vegetation loss and the 2016 Oropouche fever outbreak in Peru
BACKGROUND Oropouche virus causes Oropouche fever, an arboviral disease transmitted mainly by midges of the genus Culicoides and Culex mosquitoes. Clinical presentation of Oropouche fever in humans includes fever, headache, rash, myalgia, and in rare cases spontaneous bleeding and aseptic meningitis. Landscape change has been proposed as a driver of Oropouc

3. Modelagem da dinâmica de doenças infecciosas em redes de movimentação de animais / Modeling the dynamics of infectious diseases in networks of animal movements
A dinâmica de movimentação de animais em uma rede de propriedades rurais e o espalhamento de algumas doenças animais estão intrinsecamente relacionados. Assim, compreender a dinâmica do espalhamento de doenças infecciosas nestas redes é um instrumento importante no controle destas. Neste projeto, foram implementados algoritmos para gerar redes de mov

4. Modelagem de problemas da dinâmica de populações por meio da dinâmica estocástica / Modeling problems of population by the stochastic dynamics
Apresentamos o estudo de três modelos estocásticos governadas por equações mestras que descrevem a propagação de epidemias em uma comunidade de indivíduos;

5. Análise da associação dos protocolos de roteamento AODV e DSR com o algoritmo Gossip, sistema de Quorum e com um novo algoritmo de economia de energia, PWSave. / Association analisys of the routing protocols AODV and DSR with Gossip, Quorum system and a new algorithm, PWSave.
This work studies the implementation of the Quorum system associated with the Gossip algorithm, the implementation of a new power saving algorithm - the PWSave - and the routing protocol AODV in a scenario with and without failures of an ad hoc network with mobility. It has been chosen to implement this work in an environment of simulation, because the mathe

6. Geostatistic modeling of spatial distribution of common bean and soybean diseases and it relationship among soil fertility and mineral nutrition plants / Modelagem geoestatÃstica da distribuiÃÃo espacial de doenÃas do feijoeiro comum e da soja e sua relaÃÃo com a fertilidade do solo e nutriÃÃo mineral de plantas
The knowledge of the spatial dynamics of plant diseases and environmental factors that can influence an epidemic is very important for the definition of control strategies for efficient and sustainable management. Therefore, the objective of the present work was to evaluate the pattern of spatial distribution of white mold in two areas of winter common bean

8. Modeling the Effects of Epidemics on Routinely Collected Data
The use of routinely collected data, such as absenteeism, to provide an early warning of an epidemic will depend on better understanding of the effects of epidemics on such data. We reviewed studies in behavioral medicine and health psychology in order to build a model relating known factors related to human health information and treatment seeking behavior

9. Group interest versus self-interest in smallpox vaccination policy
The recent threat of bioterrorism has fueled debate on smallpox vaccination policy for the United States. Certain policy proposals call for voluntary mass vaccination; however, if individuals decide whether to vaccinate according to self-interest, the level of herd immunity achieved may differ from what is best for the population as a whole. We present a

10. Accurate noise projection for reduced stochastic epidemic models
We consider a stochastic susceptible-exposed-infected-recovered (SEIR) epidemiological model. Through the use of a normal form coordinate transform, we are able to analytically derive the stochastic center manifold along with the associated, reduced set of stochastic evolution equations. The transformation correctly projects both the dynamics and the noise o

11. Sporadic—but Not Variant—Creutzfeldt-Jakob Disease Is Associated with Polymorphisms Upstream of PRNP Exon 1
Human prion diseases have inherited, sporadic, and acquired etiologies. The appearance of the novel acquired prion disease, variant Creutzfeldt-Jakob disease (vCJD), and the demonstration that it is caused by the same prion strain as that causing bovine spongiform encephalopathy, has led to fears of a major human epidemic. The etiology of classical (sporadic
