| 1 | Cross-depiction problem: Recognition and synthesis of photographs and artwork显示文摘Cross-depiction is the recognition—and synthesis—of objects whether they are photographed,painted, drawn, etc. It is a significant yet underresearched problem. Emulating the remarkable human ability to recognise and depict objects in an astonishingly wide variety of depictive forms is likely to advance both the foundations and the applications of computer vision. In this paper we motivate the cross-depiction problem, explain why it is difficult, and discuss some current approaches. Our main conclusions are(i) appearance-based recognition systems tend to be over-fitted to one depiction,(ii) models that explicitly encode spatial relations between parts are more robust,and(iii) recognition and non-photorealistic synthesis are related tasks. | Peter Hall Hongping Cai Qi Wu Tadeo Corradi | 2015 | Computational Visual Media2015，1，2： | 2 |

| 3 | 2013~2017年中国空气质量改善与早产疾病负担改变显示文摘Preterm birth(PTB)is a leading cause of perinatal mortality and morbidity worldwide[1].Since maternal and fetal health protection has been included in the United Nations Sustainable Development Goals,identification of modifiable risk factors for PTB is particularly crucial.The Global Burden of Disease(GBD)Study 2019 recognized fine particulate matter(PM2.5)pollution as a risk factor for decreased gestational age and low birth weight. | Yixuan Jiang Yuan He Shenpeng Wu Renjie Chen Ying Yang Jihong Xu Ya Zhang Qiaomei Wang Haiping Shen Yiping Zhang Donghai Yan Zuoqi Peng Xudong Dong Hongping Zhang Lifang Jiang Huichu Li Yixiang Zhu Cong Liu Weidong Wang Xia Meng Tao Pei Ci Song Aaron Cohen Xu Ma Jing Cai Haidong Kan | 2022 | Science Bulletin2022，67，9： | 1 |
| 4 | Studies on reaction mechanisms and distinct chemiluminescence from cyanoimino neonicotinoids triggered by peroxymonosulfate in advanced oxidation processes显示文摘In this study, we proposed a novel method to investigate the advanced oxidation process of neonicotinoids(NNIs) from the perspective of concomitant chemiluminescence(CL) reaction. It was found that in the presence of cobalt ions with cyanoimino NNIs, acetamiprid(ACE) and thiacloprid(THI), could promote peroxymonosulfate and Ru(bpy)_(3)^(2+) to produce strong CL, but no CL occurred with nitro-involved NNIs as alternatives. Experimental dada from UV absorption spectra and chemiluminescence spectra suggested that new cyclic compounds might be formed during the reaction. Based on the results of free radical scavenging experiment and mass spectra, a new degradation and reaction mechanism of cyanoiminocontaining NNIs was proposed. ACE or THI were first attacked by SO_(4)^(·-) to form benzyl radicals, which in turn reacted with the carbon atoms of cyano group through electrophilic addition reaction in the formation of intramolecular ring. Then a redox reaction between Ru(bpy)_(3)^(3+) and imino group immediately took place with CL emission(610 nm). The new mechanistic knowledge would be meaningful for other contaminants for their interactions with PMS. | Mengdie Cai Weimin Gan Zhiqin Ding Hongping Cai Lijun Wei Xianglei Cheng | 2023 | Chinese Chemical Letters2023，34，3： | 0 |
