We modified the work of Wang and Zou , where both costs benefits fear effects were considered, a constant time delay was used to represent biomass conversion from prey predator. In our work, we assumed that digestion is not constant, but rather follows specific distribution. The modeled using general kernel function, more functional response function also employed. Then, established an integral–differential model with distributed delays. show there exists delay-dependent threshold determines...
We consider a susceptible-exposed-infected-removed (SEIR) epidemic model with discontinuous treatment strategies. The rate has at most finite number of jump discontinuities in every compact interval. By using Lyapunov theory for differential equations and other techniques on non-smooth analysis, the basic reproductive $\mathcal{R}_{0}$ is proved to be sharp threshold value which completely determines dynamics model. If $\mathcal{R}_{0}\leq 1$ , then there only exists disease-free...
In this paper, we propose a time‐delayed predator‐prey model with Holling‐type II functional response, which incorporates the gestation period and cost of fear into prey reproduction. The dynamical behavior system is both analytically numerically investigated from viewpoint stability, permanence, bifurcation. We found that there are stability switches, Hopf bifurcations occur when delay τ passes through sequence critical values. explicit formulae determine direction, other properties...
Understanding students’ psychological pressure and bad emotional reaction can solve problems as soon possible avoid affecting normal study life. With the improvement of global scientific technological strength, step-by-step in-depth research on deep learning computational intelligence optimization. Now, we have enough conditions to build a data set for field education, mental health stress detection model with analysis function. In addition, variety experimental methods are used comparison,...
Chitosan/collagen composite nanofibrous scaffold has been greatly concerned in recent years for its favorable physicochemical properties which mimic the native extracellular matrix (ECM) both morphologically and chemically. In a previous study, we had successfully fabricated chitosan/collagen by electrospinning. present further investigate biocompatibility of such nanofiber to be used as scaffolds vascular tissue engineering. The porcine iliac artery endothelial cells (PIECs) were employed...
The project goal was to reduce waste disposal volume, costs and minimize the negative impact that regulated treatment has on environment. This accomplished by diverting bypass circuits from traditional medical (RMW) clear bag waste, or municipal solid (MSW). To qualify be disposed of through MSW stream, needed void any free-flowing blood “responsibly clear.” Traditionally perfusion circuit emptied cardioplegia pump starting shortly after decannulation heparin reversal. Up 2000 mL additional...
