＜正＞This paper aims to operate the Hopfield neural network model in parallel by means of a new state updating rule,called the majority *** rule is characterized by that a neuron in a parallel Hopfield model changes its state only when the net-input is considerably larger（or smaller） than its threshold regardless of the states of other neurons that operate simultaneously. While the original Hopfield network may not converge if it operate in parallel,the convergence of the proposed parallel Hopfield network is guaranteed thanks to the novel concept of majority *** convergence property of the proposed network is theoretically proved by showing that the energy of network is always monotonically non-decreasing when a state transition with majority protocol is *** addition,this paper demonstrates its usefulness by applying the parallel Hopfield model to well-known combinatorial optimization problems.

Background Although smoking is classified as a risk factor for severe COVID-19 outcomes,there is a scarcity of studies on prevalence of smoking during the COVID-19 ***,this study aims to analyze the trends of prevalence of smoking in adolescents over the COVID-19 pandemic *** The present study used data from middle to high school adolescents between 2005 and 2021 who participated in the Korea Youth Risk Behavior Web-based survey(KYRBs).We evaluated the smoking prevalence(ever or daily)by year groups and estimated the slope in smoking prevalence before and during the *** A total of 1,137,823 adolescents participated in the study[mean age,15.04 years[95%confidence interval(CI)15.03-15.06];and male,52.4%(95%CI 51.7-53.1)].The prevalence of ever smokers was 27.7%(95%CI 27.3-28.1)between 2005 and 2008 but decreased to 9.8%(95%CI 9.3-10.3)in 2021.A consistent trend was found in daily smokers,as the estimates decreased from 5.4%(95%CI 5.2-5.6)between 2005 and 2008 to 2.3%(95%CI 2.1-2.5)in ***,the downward slope in the overall prevalence of ever smokers and daily smokers became less pronounced in the COVID-19 pandemic period than in the pre-pandemic *** the subgroup with substance use,the decreasing slope in daily smokers was significantly more pronounced during the pandemic than during the pre-pandemic *** The proportion of ever smokers and daily smokers showed a less pronounced decreasing trend during the *** findings of our study provide an overall understanding of the pandemic's impact on smoking prevalence in adolescents.

通过用DICTRA法模拟在凝固及冷却过程中磷的微观偏析行为，来分析低碳钢的磷含量和冷速对相转变的作用。本文通过相转变的模拟，材料参数像如P含量，冷速和一次枝晶间距的作用对奥氏体开始形成温度的晶粒长大都有一个明确的阐述。利用相转变可以模拟计算奥氏体晶粒长大的开始温度值，低碳钢中的奥氏体晶粒尺寸，这些都基于P含量在0．01％-0．02％之间和从1．7Ks0到800Ks^-1较宽冷速范围的一个标准晶粒长大模型。目前在100mm的厚板和2mm的薄板上奥氏体晶粒尺寸的预测与实验结果相一致。
