针对复杂环境下激光条纹中心线提取算法稳定性差、精度低等问题，提出一种基于改进U2-Net的中心线提取新方法。首先，在U2-Net网络中加入TSA（transformer-self-attention）、TCA（transformer-cross-attention）模块以提高模型的特征提取能力，实现精准像素级分割，有效去除图像中的噪声、毛刺，为后续中心线提取提供高质量的图像源；其次，根据使用场景特点，对传统Steger方法进行改进，完成激光条纹中心线高精度提取；最后，采用信度评价机制对光条中心点进行精度分析。实验结果表明，本文提出的改进U2-Net相较其他主流语义分割网络具有更高的提取精度、更好的抗噪声性能，在此基础上提取的像素中心点的信度值更高，达到传统Steger算法的1.9倍，满足高精度工业测量的需求。

背景目前儿童药物难治性癫痫(DRE)在儿童癫痫中的占比维持在30%左右,且常合并精神发育迟滞,影响患儿生活质量,因此DRE的诊疗仍然是神经病学的重大挑战。目的分析儿童DRE的遗传学特点及临床特征,为临床进行基因检测提供理论依据。方法回顾性选取2020—2022年于河北省儿童医院住院治疗且完善基因检测的95例DRE患儿为研究对象,根据基因检测结果分为基因突变阳性组(44例)和基因突变阴性组(51例)。收集患儿的一般资料(包括性别、发病年龄、用药情况、发热惊厥史、癫痫家族史等)、临床特征(发作类型、癫痫综合征、发育情况)、辅助检查[基因检测、视频脑电图(VEEG)检查、神经影像学检查],分析DRE的遗传病因及临床特征。结果95例DRE患儿中,男55例(57.9%)、女40例(42.1%),中位发病年龄为1.00(0.50,4.00)岁,用药数量为3(2,4)种;基因突变阳性组患儿发病年龄小于基因突变阴性组(Z=-5.322,P=0.001);两组患儿性别、发热惊厥史、癫痫家族史、用药数量比较,差异均无统计学意义(P>0.05)。38例(40.0%)的患儿确诊为癫痫综合征,其中76.3%(29/38)在新生儿或婴儿期发病;基因突变阳性组患儿癫痫综合征占比高于基因突变阴性组(χ^(2)=12.065,P=0.001)。临床发作类型多样,最常见的为2种及以上发作类型,占52.6%(50/95),其次为单一局灶性发作,占33.7%(32/95);两组DRE患儿发作类型比较,差异无统计学意义(χ^(2)=2.920,P=0.404)。57例患儿完善了发育筛查,其中43例(75.4%)在发病后出现不同程度的发育迟缓,33例(76.7%)表现为全面性发育迟缓;基因突变阳性组患儿发育迟缓占比高于基因突变阴性组(χ^(2)=5.728,P=0.017)。44例患儿检出变异基因,阳性检出率为46.3%,其中以离子通道类变异为主,SCN1A为最常见的单基因突变。90例(94.7%)患儿VEEG检查异常,以局灶性癫痫放电为主;基因突变阳性组患儿高峰失律占比高于基因突变阴性组(χ^(2)=7.425,P=0.006)。25例(26.3%)患儿存在结构性病因,其中基因突变阳性组12例,基因突变阴性组13例;两组DRE患儿结构性病因比较,差异无统计学意义(χ^(2)=0.039,P=0.844)。结论遗传因素为儿童DRE的重要病因,提示发病年龄小、发育迟缓与遗传性病因有关,应积极早期完善基因检测,有助于早期诊断DRE并精准治疗。

A survey of weak stability boundaries in the sun-Mars system

引用

Research in Astronomy and Astrophysics 2015年第3期15卷 376-392页

作者： Jian Li Yi-Sui sun School of Astronomy and Space Science & Key Laboratory of Modern Astronomy and Astrophysics in Ministry of Education Nanjing University

We investigate the weak stability boundary （WSB） for a new primary, Mars, in the framework of the planar circular restricted 3-body problem, and also in the pla- nar bicircular restricted 4-body problem by including a perturbation due to Jupiter. For the sake of a simple stability/instability criterion, our computations have been done us- ing the equations of motion in polar coordinates. It is found that the relative size of the weakly stable sets around Mars is much larger than that of the Earth-Moon and the sun-Jupiter systems, as the mass ratio of the sun-Mars system is significantly smaller. We propose that this difference could be scaled by the Hill radius. In an enlarged view of the domain close to Mars, the geometry of the WSB has been presented for various parameters and compared to previous works. Our results also show that Jupiter＇s grav- itational force would strongly affect the Martian stable regions and should be taken into account to design a ballistic capture trajectory.
