Abstract The phenomenon of bifurcation in disease transmission models has 151 been observed in a number of epidemiological models.The consequence of bifurcation is that the classical requirement of the reproduction number being less than unity becomes only a necessary, but not sufficient, for disease elimination.This paper addresses the problem of
Abstract Retinopathy of prematurity (ROP) is one of the main causes of blindness in children.Timely prevention and treatment can effectively control its progression.Although convolutional neural networks (CNNs) have been widely studied in the field of ROP detection, limitations such as parameter redundancy, spatial information loss, and limited int
Efficient and accurate modeling of rock deformation and well production in weakly A consolidated reservoirs requires reliable and accurate reservoir modeling techniques.During hydrocarbon production, the reservoir pressure is dropped, and rock compaction is induced.In such depletion-induced reservoir rock deformation, both elastic and plastic defor
Pesticide and veterinary drug residues in agricultural products are one of the main problems in the field of food safety.It is necessary to test the residual content of these drugs and set strict limits.At present, adsorption extraction materials such as zeolite and multi-walled carbon nanotubes have the problems of low adsorption capacity and easy
