| 1 | Development and Lubricating Properties of Rolling Oil for Stainless Steel Cold Rolling显示文摘Appropriate base oils and homologous additives such as extreme pressure and anti-wear agents,oiliness agents and antioxidants were selected,and experiments testing the compatibility performance between additive,base oil and other components were carried out to develop the SK and SD series of rolling oils for cold rolling of stainless steel.The developed oils were used in the stainless steel cold rolling lubrication experiments,and were successfully applied in the actual cold rolling operation of stainless steel.Compared with a foreign product,the tribological properties,the thermal oxidation stability,and the rolling lubrication performance of the developed stainless steel cold rolling oils were studied.Test results showed that the tribological properties of the thereby developed rolling oils and the reference one were almost at the same level,and to some extent the performance of rolling was even better than the foreign product,at the same time the stainless steel sheet could retain its well annealed performance.Meanwhile,within a certain range,the lubrication of the rolling oil became better as its viscosity increased at the same level of saponification value,which could provide a lower friction coefficient,so that a higher maximum reduction ratio of the rolled piece through a constant roll gap and a minimum thickness could be secured.Also,similar phenomena appeared as the saponification value increased at a same viscosity level of the rolling oils. | Zhang Xu Wang Yizhu Yao Wenjing Sun Jianlin Wang Shiting | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，2： | 4 |
| 2 | Control measures during the COVID-19 outbreak reduced the transmission of hand,foot,and mouth disease显示文摘Control measures during the coronavirus disease 2019(COVID-19)outbreak may have limited the spread of infectious diseases.This study aimed to analyze the impact of COVID-19 on the spread of hand,foot,and mouth disease(HFMD)in China.A mathematical model was established to fit the reported data of HFMD in six selected cities in China's Mainland from 2015 to 2020.The absolute difference(AD)and relative difference(RD)between the reported incidence in 2020,and simulated maximum,minimum,or median incidence of HFMD in 2015-2019 were calculated.The incidence and R effof HFMD have decreased in six selected cities since the outbreak of COVID-19,and in the second half of 2020,the incidence and R effof HFMD have rebounded.The results show that the total attack rate(TAR)in 2020 was lower than the maximum,minimum,and median TAR fitted in previous years in six selected cities(except Changsha City).For the maximum,median,minimum fitted TAR,the range of RD(%)is 42·20-99·20%,36·35-98·41%48·35-96·23%(except Changsha City)respectively.The preventive and control measures of COVID-19 have significantly contributed to the containment of HFMD transmission. | Yan Niu Li Luo Jia Rui Shiting Yang Bin Deng Zeyu Zhao Shengnan Lin Jingwen Xu Yuanzhao Zhu Yao Wang Meng Yang Xingchun Liu Tianlong Yang Weikang Liu Peihua Li Zhuoyang Li Chan Liu Jiefeng Huang Tianmu Chen | 2021 | Journal of Safety Science and Resilience2021，2，2： | 3 |
| 3 | Microwave triggered multifunctional nanoplatform for targeted photothermal-chemotherapy in castration-resistant prostate cancer显示文摘Lacking a precise targeting strategy,castration-resistant prostate cancer(CRPC)is still hard to be treat effectively.Exploring treatment options that can accurately target CPRC is an important issue with urgent need.In this study,a novel nanotechnologybased strategy had been developed for the precise target treatment of CRPC.By combining microwaves and photothermal therapy(PTT),this nanoplatform,cmHSP70-PL-AuNC-DOX,targets tumor tissues with outstanding precision and achieves better anti-tumor activity by simultaneously eliciting photothermal and chemotherapeutic effects.From nanotechnology,cmHSP70-modified and thermo-sensitive liposome-coated AuNC-DOX were prepared and used for CRPC-targeted photothermal ablation and chemotherapy.Doxorubicin(DOX)was selected as the chemotherapeutic agent for cytotoxicity.In terms of the curative scheme,prostate tissues were firstly pre-treated with microwaves to induce the expression of heat shock protein 70(HSP70)and its migration to the cell membrane,which was then targeted by HSP70 antibody(cmHSP70)coated on the nanoparticles to achieve accurate drug delivery.The nanoplatform then achieved precise ablation and controlled release of DOX under external near-infrared(NIR)irradiation.Through the implementation,the targeting,cell killing,and safety of this therapeutical strategy had been verified in vivo and in vitro.This work establishes an accurate,controllable,efficient,non-invasive,and safe treatment platform for targeting CRPC,provides a rational design for CRPC’s PTT,and offers new prospects for nanomedicines with great precision. | Pengyuan Liu Yajun Wu Xiaogang Xu Xudong Fan Chuan Sun Xiaojie Chen Jindan Xia Shiting Bai Li Qu Huasong Lu Jing Wu Jun Chen Ji-Gang Piao Zhibing Wu | 2023 | Nano Research2023，16，7： | 2 |

| 5 | Feasibility of Booster Vaccination in High-Risk Populations for Controlling Coronavirus Variants—China,2021显示文摘Introduction:Vaccination booster shots are completely necessary for controlling breakthrough infections of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in China.The study aims to estimate effectiveness of booster vaccines for high-risk populations(HRPs).Methods:A vaccinated Susceptible-Exposed-Symptomatic-Asymptomatic-Recovered/Removed(SEIAR)model was developed to simulate scenarios of effective reproduction number(Reff)from 4 to 6.Total number of infectious and asymptomatic cases were used to evaluated vaccination effectiveness.Results:Our model showed that we could not prevent outbreaks when covering 80%of HRPs with booster unless Reff=4.0 or the booster vaccine had efficacy against infectivity and susceptibility of more than 90%.The results were consistent when the outcome index was confirmed cases or asymptomatic cases.Conclusions:An ideal coronavirus disease 2019(COVID-19)booster vaccination strategy for HRPs would be expected to reach the initial goal to control the transmission of the Delta variant in China.Accordingly,the recommendation for the COVID-19 booster vaccine should be implemented in HRPs who are already vaccinated and could prevent transmission to other groups. | Kangguo Li Zeyu Zhao Hongjie Wei Jia Rui Jiefeng Huang Xiaohao Guo Yichao Guo Shiting Yang Guzainuer Abudurusuli Li Luo Xingchun Liu Yao Wang Jingwen Xu Yuanzhao Zhu Meng Yang TianlongYang Weikang Liu Bin Deng Chan Liu Zhuoyang Li Peihua Li Shanshan Yu Zimei Yang Yanhua Su Benhua Zhao Yan Niu Tianmu Chen | 2021 | China CDC weekly2021，3，50： | 2 |
| 6 | Material patterning on substrates by manipulation of fluidic behavior显示文摘Patterned materials on substrates are of great importance for a wide variety of applications.In solution-based approaches to material patterning;fluidic flow is inevitable.Here we demonstrate not only the importance of fluidic behavior but also the methodology of engineering the flow pattern to guide the material crystallization and assembly.We show by both experiment and simulation that substrate heating;which is generally used to accelerate evaporation,produces irregular complex vortexes.Instead;a top-heating-bottom-cooling(THBC)set-up offers an inverse temperature gradient and results in a single Marangoni vortex,which is desired for ordered nanomaterial patterning near the contact line.We then realize the fabrication of large-scale patterns of iodide perovskite crystals on different substrates under THBC conditions.We further demonstrate that harnessing the flow behavior is a general strategy with great feasibility to pattern various functional materials ranging from inorganic;organic,hybrid to biological categories on different substrates,presenting great potential for practical applications. | Yitan Li Hao Wang Henglu Xu Shiting Wu Xuemei Li Jiapeng Yu Chaoyu Huang Zeyao Zhang Hao Sun Lu Han Meihui Li Anyuan Cao Zhenhai Pan Yan Li | 2019 | National Science Review2019，6，4： | 0 |
| 7 | Monocular Depth Estimation with Sharp Boundary显示文摘Monocular depth estimation is the basic task in computer vision.Its accuracy has tremendous improvement in the decade with the development of deep learning.However,the blurry boundary in the depth map is a serious problem.Researchers find that the blurry boundary is mainly caused by two factors.First,the low-level features,containing boundary and structure information,may be lost in deep networks during the convolution process.Second,themodel ignores the errors introduced by the boundary area due to the few portions of the boundary area in the whole area,during the backpropagation.Focusing on the factors mentioned above.Two countermeasures are proposed to mitigate the boundary blur problem.Firstly,we design a scene understanding module and scale transformmodule to build a lightweight fuse feature pyramid,which can deal with low-level feature loss effectively.Secondly,we propose a boundary-aware depth loss function to pay attention to the effects of the boundary’s depth value.Extensive experiments show that our method can predict the depth maps with clearer boundaries,and the performance of the depth accuracy based on NYU-Depth V2,SUN RGB-D,and iBims-1 are competitive. | Xin Yang Qingling Chang Shiting Xu Xinlin Liu Yan Cui | 2023 | Computer Modeling in Engineering & Sciences2023，，7： | 0 |
