The prognostic value of lymphocyte-to-monocyte ratio in retinopathy of prematurity

引用

International Journal of Ophthalmology(English edition) 2017年第11期10卷 1716-1721页

作者： Yu-Xiang Hu Xiao-Xuan Xu Yi Shao gao-le yuan Feng Mei Quan Zhou Yi Cheng Jun Wang Xiao-Rong Wu Department of Ophthalmology the First Affiliated Hospital of Nanchang University Nanchang 330006 Jiangxi Province China Department of Pediatrics the First Affiliated Hospital of Nanchang University Nanchang 330006 Jiangxi Province China Second Department of Respiratory Disease Jiangxi Provincial People's Hospital Nanchang 330006 Jiangxi Province China

AIM： To evaluate the associations between development of retinopathy of prematurity（ROP） and serum lymphocyteto-monocyte ratio（LMR）, neutrophil-to-lymphocyte ratio（NLR）, and platelet-to-lymphocyte ratio（PLR）. METHODS： A retrospective cohort study was performed, involving infants who were screened for ROP from January 2015 to December 2015. Preterm newborns of ≤32 gestational weeks with ROP were enrolled as the observation group, and non-ROP infants were enrolled as the control group, whose complete blood cell were measured within the first 24 h of life. The levels of NLR, LMR and PLR were determined in all groups. The data obtained were analyzed using univariate and multivariate logistic regression ***： In this study, 40 cases of ROP were enrolled and 40 cases of non-ROP as controls. The LMR levels were significantly higher（P〈0.001） in ROP group（3.96±1.16） compared to non-ROP group（2.85±0.79）. The NLR levels were significantly lower（P=0.035） in ROP group {median [interquartile range（IQR）], 0.88（0.67-1.46）} compared to non-ROP group [median（IQR）, 1.20（0.85-1.89）]. The median PLR values were 61.99（IQR, 50.23-75.98） in ROP group and 69.24（IQR, 55.52-88.12） in non-ROP group（P=0.104）. Logistic regression analysis suggested that LMR was an independent risk factor for ROP（OR： 0.275; 95% CI： 0.134-0.564; P=0.001）. CONCLUSION： The findings demonstrate that higher LMR is independently and significantly associated with the development of ROP, and the LMR may be invoked as a predictive tool for identifying risk for ROP.

The Investigation of Data Voting Algorithm for Train Air-Braking System Based on Multi-Classification SVM and ANFIS

引用

Chinese Journal of Electronics 2024年第1期33卷 274-281页

作者： Juhan WANG Ying gao yuan CAO Tao TANG School of Electronics and Information Engineering Beijing Jiaotong University Graduate Department China Academy of Railway Science National Engineering Research Center of Rail Transportation Operation and Control System Beijing Jiaotong University

The pressure data of the train air braking system is of great significance to accurately evaluate its operation state. In order to overcome the influence of sensor fault on the pressure data of train air braking system, it is necessary to design a set of sensor fault-tolerant voting mechanism to ensure that in the case of a pressure sensor fault, the system can accurately identify and locate the position of the faulty sensor, and estimate the fault data according to other normal data. A fault-tolerant mechanism based on multi-classification support vector machine(SVM) and adaptive network-based fuzzy inference system(ANFIS) is introduced. Multi-classification SVM is used to identify and locate the system fault state, and ANFIS is used to estimate the real data of the fault sensor. After estimation, the system will compare the real data of the fault sensor with the ANFIS estimated data. If it is similar,the system will recognize that there is a false alarm and record it. Then the paper tests the whole mechanism based on the real data. The test shows that the system can identify the fault samples and reduce the occurrence of false alarms.

《尚书考异》是第一部系统考辨《古文尚书》为伪作的著作,具有重要的学术研究价值。关于此书版本。较有价值的是台湾故宫藏旧抄本、《四库全书》文渊阁抄本、孙星衍平津馆刻本。台湾故宫藏旧抄本年代最早,有了它,可以大体推测《尚书考异》在传写过程中致误之由。文渊阁抄本最为常见,四库馆臣在将此书收入《四库全书》时,对书中许多讹误作了校正。平津馆刻本最为完整,它不仅比前两个抄本多出两万余字。而且更全面而系统地对《古文尚书》进行了辨伪搜证工作。但此本虽经顾广圻、孙星衍两位清代大学者"详加校正",但书中仍沿袭了故宫旧抄本的许多错误。这也就是说,《尚书考异》迄今尚无一部理想的版本。本文通过《尚书考异》版本的比较研究,以见各版本的优缺点及其价值。

作者： Fanfan LV Wei WANG Jinjin LI yuan gao Kuaishe WANG College of Metallurgical Engineering Xi’an University of Architecture and TechnologyXi’an710055China State Key Laboratory of Tribology in Advanced Equipment Tsinghua UniversityBeijing10084China

Black phosphorus (BP) is a new class of two-dimensional (2D) layered material, which shows the unanticipated characteristics in many aspects including electronics, transistors, sensors, energy storage, batteries, photocatalysis, and other applications due to its high charge carrier mobility, tunable direct bandgap, and unique in-plane anisotropic structure. In addition, BP has drawn tremendous attention in the field of tribology due to the low shear strength, the layered structure, and the weak connected force between the layers by van der Waals interaction. In recent years, many significant progresses have been made in experimental studies on BP materials as solid lubricants or lubrication additives. This work offers a review of researching regarding the tribological properties of BP. Moreover, the lubrication mechanisms of BP as the lubrication additive including the formation of the tribo-film, micro-bearing effect, and self-repair performance are also summarized. Finally, the current challenges and prospects of BP material as lubricant are proposed.
