针对电力设备检测中小目标识别精度低的问题,提出一种基于RetinaNet的电力设备目标检测方法。通过K-means聚类方法优化原始网络的锚点框尺寸。然后在特征融合中加入拥有更高分辨率的浅层特征图,解决通过多层卷积后特征图包含信息过少的问题。在此基础上,引入ECA(Efficient Channel Attention)注意力机制,使网络定位电力设备的有效特征,抑制无用特征信息。实验结果表明,相比原始方法,本文方法对于电塔、销钉、工程车、绝缘子、电杆5种电力设备的平均识别精度提升了18.1个百分点,表明改进后的方法能显著提高电力设备的检测水平。

Background： Polycystic ovary syndrome （PCOS） and its characteristic symptoms have been associated with physical and psychological issues in women of reproductive age. The current study was conducted in response to the dearth of systematic research related to psychological functioning and quality of life in patients with PCOS in Southwest China, and to determine whether patients with PCOS exhibit poorer mental health （MH） compared to healthy women of the same age and living in the same region, without a PCOS diagnosis. Methods： We enrolled 120 outpatients with PCOS and 100 healthy controls in this study. Standardized questionnaires were administered to assess general MH conditions （General Health Questionnaire-12-item version）, anxiety （State-Trait Anxiety Inventory）, depression （Beck Depression Inventory）, as well as health-related quality of life （HRQoL） measured using the 36-item short-form health survey. The independent samples t-test was conducted for continuous study variables. For categorical variables, the Pearson Chi-square test, Fisher＇s exact test, and logistic regression were perlbrmed. Results： The prevalence of anxiety （13.3% vs. 2.0%） and depression （27.5% vs. 3.0%） was higher in patients with PCOS compared to the controls （both P 〈 0.05）. Patients with PCOS had decreased HRQoL. Patients with PCOS who had fertility requirements were more likely to be anxious and depressed than those without fertility requirements （anxiety： 22.6% [1 2/53] vs. 5.9% [4/67],Z： = 7.117, P = 0.008： depression： 37.7% （20/53） vs. 19.4% （13/67）, Х^2 = 4.988, P - 0.026）. Conclusions： PCOS and related synaptoms may be risk factors for depression and anxiety. Professionals should be concerned with the MH of women with PCOS, and psychological therapy should be considered.

Analytic expressions have been derived of the alternating current(ac)Zeeman and ac Stark effect in an atomic beam magnetic resonance method using Ramsey separated oscillating *** interesting feature which will affect the normal Ramsey pattern is that an interference fringe is superimposed on the dispersion lineshapes of the normal ac Zeeman or ac Stark *** point out that this new character of ac Zeeman(ac Stark)effect generally exists in all kinds of Ramsey method,for example,in the optical Ramsey atomic interferometer and atomic beam frequency *** important implication is that,particularly in an atomic beam frequency standard using Ramsey method,this effect has an influence on the evaluation of the second-order Doppler frequency shift.
