为了实现对肝癌的早期实时和在体探测,基于前期搭建的光纤共聚焦后向散射(FCBS)光谱仪获取肝癌细胞的显微后向散射光谱,分别使用主成分分析(PCA)和支持向量机(SVM)两种算法,对获得的正常肝细胞株(L02)、低转移潜能肝癌细胞株(MHCC97-L)和高转移潜能肝癌细胞株(HCCLM3)三种细胞的后向散射光谱进行分类。使用PCA对获得的三种细胞光谱数据进行降维分析,得到的前两个主成分综合了全部信息的95.4%,由主成分1和主成分2的得分图可以观察到,三种细胞在直观上有明显的区分;对同一数据集选取69例对象通过SVM机器学习算法训练分类模型,随机抽取50例作为训练集,19例作为预测集,最终分类的准确度达到了94.7%。实验结果表明:使用光纤共聚焦后向散射(FCBS)光谱仪获取的细胞显微后向散射光谱可以分别通过PCA和SVM对不同转移潜能的肝癌细胞进行自动分类,这将为研究活检提供必要的检测手段。

光纤的几何参数是评价光纤是否符合使用要求的重要指标。常用的几何参数测量方法为近场光分布法,这种方法对光纤端面图像的质量有很高的要求,当光纤端面的切割不平整或照明条件较差时,几何参数的测量会出现较大的误差。本文采用椭圆函数对图像边缘点拟合的方法,先设定自适应的阈值,在剔除超出边界阈值的误差数据点后,再次进行函数拟合,以此循环,直至所有数据点均在阈值内,最后得到一个最佳的拟合椭圆。以光纤纤芯测量为例,标准仪器测得直径和不圆度为8.420μm和0.670%,当光纤切割或照明条件不好时,仪器的测量值变为9.044μm和1.457%。而本文方法前后的测量值分别为8.420μm、8.664μm和0.815%、0.493%。对比数据发现,多次函数拟合法可以有效提高光纤几何参数的测量准确度与精度。

尽管纹身的人数在增加,但希望祛除纹身的需求量也在增加。现在纹身祛除大多采用激光进行治疗,但仅凭肉眼观察的单次疗效不够理想,往往需要重复治疗。因此,研究了基于图像技术量化评价治疗的效果。使用皮秒激光对猪皮的不同颜色的纹身进行照射,采集治疗部位与正常皮肤组织的图像,再标准化提取部位,并对此部位的图像进行特征提取后,量化照射前后的纹身所占面积比,进而得到祛除率。为了验证量化算法的可靠性,设计了不同对比度的标准图像来计算色素占比,得到的误差均小于0.01%,证明该算法是可靠的。对于色素祛除的量化评价能客观反映激光祛除色素的效果,避免了因医师的主观判断所造成的疗效偏差,为治疗参数的选择及疗效的提高等提供了帮助。

The decay channel ψ′→ π 〉＋π^-J/ψ（J/ψ 〉 γp^-p） is studied using a sample of 1.06 × 10^8 ψ′ events collected by the BESIII experiment at BEPCII. A strong enhancement at threshold is observed in the p^-p invariant mass spectrum. The enhancement can be fitted with an S-wave Breit-Wigner resonance function with a resulting peak mass of M = 1861-13^＋6 （stat）-26^＋7 （syst） MeV/c^2 and a narrow width that is Г 〈 38 MeV/c^2 at the 90% confidence level. These results are consistent with published BESII results. These mass and width values do not match with well established mesons.
