We propose a theoretical study investigating the spread of novel coronavirus (COVID-19) reported in Wuhan City China 2019. develop mathematical model based on corona virus's characteristics and then use fractional calculus to fractionalize it. Various order epidemic models have been formulated analyzed using number iterative numerical approaches while complications arise due singular kernel. we...
Refined epidemiological model forecasts new cases of the COVID-19 Omicron variant
Introduction: The usage of valid, reliable, rapid and low cost instruments for measurement of physical activity (PA) volume are essential in epidemiological and clinical studies. The purpose of this study was to develop a new physical activity prediction model using physiological and anthropometric variables in middle aged men. Methods: Daily physical activity was measured with pedometer throug...
the links between disasters and violence either self-directed or interpersonal are now more recognized. nevertheless, the amount of research is limited. this article discusses the underlying association of disasters and violence and it also outlines a systematic review of the literature from 1976 to 2011. finally, it concludes and recommends particular approaches for further epidemiological res...
Multiple infections are known to affect virulence evolution. Some studies even show that coinfections may decrease the overall virulence (the disease-induced mortality of a coinfected host). Yet, epidemiological studies tend to overlook the overall virulence, and within-host models tend to ignore epidemiological processes. Here, I develop an epidemiological model where overall virulence is an e...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
In this article, we discuss the structural and practical identifiability of a nested immuno-epidemiological model of arbovirus diseases, where host-vector transmission rate, host recovery, and disease-induced death rates are governed by the within-host immune system. We incorporate the newest ideas and the most up-to-date features of numerical methods to fit multi-scale models to multi-scale da...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
The control, prediction, and understanding of epidemiological processes require insight into how infectious pathogens transmit in a population. The chain of transmission can in principle be reconstructed with phylogenetic methods which analyze the evolutionary history using pathogen sequence data. The quality of the reconstruction, however, crucially depends on the underlying epidemiological mo...
