Today ABR ABR: Auditory B ainstem Responses) characteristics are widely and qualitatively used, and they ar e mainly used for clinical application of a consciousness obstacle, brain death and some consciousness level, vegetative state and so on, as the very useful inspection method. Until now, many various characteristics and models about these brain waves have been reported. But the theor ies and experiments of ABR are still more needed to understand the ABR characters in more details. In this paper we discussed the analysis of a differ ential equation model on the latency of the 5th wave of ABR, and considered the system model of generation of the type of solution of the differential equation model on the basis of an estimation of parameters of a solution of its equation model by using the Taylor ser ies method as an iterative approximation method.

Large-scale optimal design problems involving nonlinear differential equations are widely applied in modeling such as craft manufacturing, chemical engineering and energy engineering. Herein we propose a fast and flexible holomorphic embedding-based method to solve nonlinear differential equations quickly, and further apply it to handle the industrial application of reverse osmosis desalination. Without solving nonlinear differential equations at each discrete point by a traditional small-step iteration approach, the proposed method determines the solution through an approximation function or approximant within segmented computational domain independently.

The aim of this study was to assess the effect of nutrition education and counseling using health belief health model constructs along with iron-folic acid supplementation on hemoglobin level and adherence to IFAs during pregnancy. The study was a three-month quasi-experimental study design in Butajira town, Ethiopia. Community-based nutrition education and counseling sessions using the Health belief model, and IFAS for six weeks were given to the pregnant women.

Accurately predicting the phase behavior and properties of reservoir fluid plays an essential role in the simulation of petroleum recovery processes. Similar to the inaccurate liquid-density prediction issue in the isobaric-isothermal (PT) phase equilibrium calculations, an inaccurate pressure prediction issue can also be observed in isothermal-isochoric (VT) phase equilibrium calculations which involves a liquid phase. In this work, a practical methodology is proposed to incorporate a volume-translated equation of state in VT phase equilibrium calculations for more accurate pressure predictions.

This study employed structural equation modeling (SEM) and geographically weighted regression (GWR) to investigate the various impacts and spatial variations in the factors influencing the HFMD epidemic in Hubei Province from 2016 to 2018. The results indicated that (1) with respect to the direct effects, the number of primary school students had the greatest positive direct effect on the number of HFMD cases, with a coefficient of 0.

We present a nonlinear model of thermal field emission in resonant tunneling nanostructures with multiple barriers and potential wells, based on an accurate determination of the quantum potential shape and a rigorous solution of the Schrödinger equation, while considering thermal balance. The model applies to vacuum and semiconductor resonant tunnel diode and triode structures with two and three electrodes and to the general case of two-way tunneling with electrode heating. The complete balance of heat release and transfer is accounted for, with heat transport considered ballistic.
