Purpose:This research examined road traffic injury mortality and morbidity disparities across of country development status,and discussed the possibility of reducing country disparities by various actions to accelerate the pace of achieving Sustainable Development Goals target 3.6 e to halve the number of global deaths and injuries from road traffic accidents by ***:Data for road traffic mortality,morbidity,and socio-demographic index(SDI)were extracted by country from the estimates of the Global Burden of Disease study,and the implementation of the three types of national actions(legislation,prioritized vehicle safety standards,and trauma-related post-crash care service)were extracted from the Global Status Report on Road Safety byWorld Health *** fitted joinpoint regression analysis to identify and quantify the significant rate changes from 2011 to ***:Age-adjusted road traffic mortality decreased substantially for all the five SDI categories from 2011 to 2017(by 7.52%e16.08%).Age-adjusted road traffic mortality decreased significantly as SDI increased in the study time period,while age-adjusted morbidity generally increased as SDI *** analysis by road user yielded similar results,but with two major differences during the study period of 2011 to 2017:(1)pedestrians in the high SDI countries experienced the lowest mortality(1.68e1.90 per 100,000 population)and morbidity(110.45e112.72 per 100,000 population for incidence and 487.48e491.24 per 100,000 population for prevalence),and(2)motor vehicle occupants in the high SDI countries had the lowest mortality(4.07e4.50 per 100,000 population)but the highest morbidity(428.74e467.78 per 100,000 population for incidence and 1025.70e1116.60 per 100,000 population for prevalence).Implementation of the three types of national actions remained nearly unchanged in all five SDI categories from 2011 to 2017 and was consistently stronger in the higher SDI countries than in the lower SD

对于不平衡数据分类问题,传统的随机梯度下降方法在求解一般的支持向量机问题时会产生一定的偏差,导致效果较差。自适应随机梯度下降算法定义了一个分布p,在选择样例进行迭代更新时,其依据分布p而非依据均匀分布来选择样例,并且在优化问题中使用光滑绞链损失函数。对于不平衡的训练集,依据均匀分布选择样例时,数据的不平衡比率越大,多数类中的样例被选择的次数就越多,从而导致结果偏向少数类。分布p在很大程度上解决了这个问题。普通的随机梯度下降算法没有明确的停机准则,这导致何时停机成为一个很重要的问题,尤其是在大型数据集上进行训练时。以训练集或训练集的子集中的分类准确率为标准来设定停机准则,如果参数设定恰当,算法几乎可以在迭代的早期就停止,这种现象在大中型数据集上表现得尤为突出。在一些不平衡数据集上的实验证明了所提算法的有效性。

基于29根钢管轻集料混凝土试件抗剪试验,研究材料性能、截面特性、剪跨比及轴压比对钢管轻集料混凝土试件的破坏形态、抗剪承载力的影响。将试验实测值与相关公式计算值进行对比,通过分析、回归试验结果,得到抗剪承载力计算公式。分析结果表明:剪跨比λ0.85施加轴压力的试件为弯曲型破坏。剪跨比越大,试件抗剪承载力越小;轴压比越大,试件抗剪承载力越大,且延性越好;轻集料混凝土强度对试件抗剪承载力影响不明显;含钢率越高,试件抗剪承载力越大。考虑以上影响因素得出抗剪承载力计算公式,试验值与计算值吻合较好,且偏于安全。

父亲是位儒雅的学者，慈祥又多才多艺。记得小时候最开心的就是看父亲画画。吃过晚饭，父亲刚刚坐到写字台前，我就迅速地爬上他的膝盖，给他戴好老花镜，母亲拿来一块可以画水彩的纸和笔，父亲按照我要画的主题挑选出合适的水彩颜料……我屏住呼吸，兴奋地看着他神奇的笔尖在水、调色盘和画纸上有节奏的轻轻拂过，魔术般地在纸上浮现出各种梦幻般的风景和神奇的房子。此时，全家早已融入了那画意中……父亲很瘦，身体又差，每次我都是坐到他抱不动我才下来。在我熟睡后，父亲才在灯下伏案工作、研究。
