| 3 | In situ optical backpropagation training of diffractive optical neural networks显示文摘Training an artificial neural network with backpropagation algorithms to perform advanced machine learning tasks requires an extensive computational process.This paper proposes to implement the backpropagation algorithm optically for in situ training of both linear and nonlinear diffractive optical neural networlks,which enables the acceleration of training speed and improvement in energy efficiency on core computing modules.We demonstrate that the gradient of a loss function with respect to the weights of diffractive layers can be accurately calculated by measuring the forward and backward propagated optical fields based on light reciprocity and phase conjunction principles.The diffractive modulation weights are updated by programming a high-speed spatial light modulator to minimize the error between prediction and target output and perform inference tasks at the speed of light.We numerically validate the effectiveness of our approach on simulated networks for various applications.The proposed in situ optical learning architecture achieves accuracy comparable to in silico training with an electronic computer on the tasks of object dlassification and matrix-vector multiplication,which further allows the diffractive optical neural network to adapt to system imperfections.Also,the self-adaptive property of our approach facilitates the novel application of the network for all-optical imaging through scattering media.The proposed approach paves the way for robust implementation of large-scale difractive neural networks to perform distinctive tasks all-optically. | TIANKUANG ZHOU LU FANG TAO YAN JIAMIN WU YIPENG LI JINGTAO FAN HUAQIANG WU XING LIN QIONGHAI DA | 2020 | Photonics Research2020，8，6： | 11 |

| 7 | Applying the China-PAR Risk Algorithm to Assess 10-year Atherosclerotic Cardiovascular Disease Risk in Populations Receiving Routine Physical Examinations in Eastern China显示文摘Objective To assess the 10-year Atherosclerotic Cardiovascular Disease(ASCVD) risk score among adults in eastern China using the China-PAR equation which formulated primarily for the Chinese population. Methods Data from 72,129 individuals from 35-74 years old who received routine physical examinations in eastern China were analyzed in this study. The 10-year risk scores were calculated using the China-PAR equation. The chi-square test and logistic regression were then performed to evaluate the association between the selected risk factors and overall CVD risk. Results The mean 10-year ASCVD risk scores were 3.82% ± 3.76% in men and 1.30% ± 1.65% in women based on the China-PAR equation. Overall, 20% of men and 3.5% of women were intermediate-risk, and 7.3% of men and 0.3% of women were high-risk. Waist to hip ratio(WHR) [OR = 1.16(CI 95% = 1.06-1.26)], waist to height ratio(WHtR) [OR = 1.16(CI 95% = 1.05-1.28)], non-high-density lipoprotein cholesterol(non-HDL-C) [OR = 1.23(CI 95% = 1.09-1.39)], and total cholesterol(TC)/HDL-C [OR = 1.68(CI 95% = 1.46-1.94)] were more strongly associated with CVD risk than body-mass index(BMI), waist circumference(WC), and TC alone. Conclusion Male-specific prevention and treatment strategies for ASCVD are needed in eastern China. In addition, WHR, WHtR, non-HDL-C, and TC/HDL-C which not included in the the China-PAR equation were also independently associated with 10-year ASCVD risk score categories. | LI Hui Hua HUANG Shan LIU Xing Zhen ZOU Da Jin | 2019 | Biomedical and Environmental Sciences2019，32，2： | 9 |

| 9 | An action-based Markov chain modeling approach for predicting the window operating behavior in office spaces显示文摘Reliable energy and performance prediction for building design and planning is important for newly-designed or retrofitted buildings.Window operating behavior has an important influence on the ventilation and energy consumption of these buildings under different realistic scenarios.Therefore,quantitatively describing this behavior and constructing a prediction model are important.In this work,an action-based Markov chain modeling approach for predicting window operating behavior in office spaces was proposed.Two summer measurement data(2016 and 2018)were used to verify the accuracy and validity of the modeling approach.The opening rate,outdoor temperature,time distribution,and on-off curve were proposed as four inspection standards.This study also compared the prediction performance between the action-based Markov chain modeling approach with the state-based Markov chain modeling approach,which is the most popular modeling approach to model occupant window operating behavior.This study proved that the yearly variation of occupants’behavior performed a form of action that remained unchanged during a certain period.Meanwhile,the results also proved that the action-based Markov chain modeling approach can reflect the actual window operating behavior accurately within an open-plan office,which is a beneficial supplement for energy-consumption simulation software in a window-state prediction module.The state-based Markov chain modeling approach showed better stability and accuracy in terms of the opening rate,whereas the action-based Markov chain modeling approach showed good consistency with the measurement data in the on-off curves and in situations with little data.For the on-off curves,the accuracy of action-based modeling approach in the prediction of window open-state is 20%higher. | Xin Zhou Tiance Liu Da Yan Xing Shi Xing Jin | 2021 | Building Simulation2021，14，2： | 7 |

| 11 | Characterization of atomic defects on the photoluminescence in two-dimensional materials using transmission electron microscope显示文摘Two-dimensional material(2D)that possesses atomic thin geometry and remarkable properties is a star material for the fundamental researches and advanced applications.Defects in 2D materials are critical and fundamental to understand the chemical,physical,and optical properties.Photoluminescence arises in 2D materials owing to various physical phenomena including activator/dopant-induced luminescence and defect-related emissions,and so forth.With the advanced transmission electron microscopy(TEM)technologies,such as aberration correction and low voltage technologies,the morphology,chemical compositions and electronic structures of defects in 2D material could be directly characterized at the atomic scale.In this review,we introduce the applications of state-of-the-art TEM technologies on the studies of the role of atomic defects in the photoluminescence characteristics in 2D material.The challenges in spatial and time resolution are also discussed.It is proved that TEM is a powerful tool to pinpoint the relationship between the defects and the photoluminescence characteristics. | Jiayan Zhang Ye Yu Peng Wang Chen Luo Xing Wu Ziqi Sun Jianlu Wang Wei Da Hu Guozhen Shen | 2019 | InfoMat2019，1，1： | 6 |
| 12 | Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications. | Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang | 2020 | Nano Research2020，13，12： | 6 |

| 14 | A refutation of reported Levallois technology from Guanyindong Cave in south China显示文摘As one of the most complex forms of lithic technology known for the Paleolithic,research on the Levallois stoneknapping method is critically relevant to our understanding of the cognitive abilities and depth of planning capabilities of archaic hominins;as well as the diffusion of knowledge and social learning in Pleistocene societies.For decades,Levallois technology was thought to be absent from East Asia for much of the Pleistocene,appearing only quite late(ca.50-40 ka BP)[1,2].In a recent paper,H u et al.claim that Levallois technology was present at the Guanyindong(GYD)site in Qianxi County,Guizhou,Province,South China by at least 170 ka BP[3].This report claims that the GYD site is an exceptional case,preserving evidence of Levallois technology earlier than 50 ka BP. | Feng Li Yinghua Li Xing Gao Steven L.Kuhn Eric Boёda John W.Olsen | 2019 | National Science Review2019，6，6： | 4 |
| 15 | High sensitive detection of presenilin-1 point mutation based on electrochemilumi-nescence显示文摘Electrochemiluminescence (ECL) is a high- sensitive detection method with broad biological applications. Ruthenium (Ⅱ) tris (bipyridyl) 2+3(Ru(bpy)) and tripro-pylamine (TPA) are most commomly used combination of the reactive species in ECL. The redox of 2+3Ru(bpy) with excess TPA at the surface of an electrode produces a highly efficient and stable light emission due to a rapid cycle of the reactions. This rapid, highly sensitive and accurate method has been applied to gene quantification. In this work, an ECL detection system is designed and applied in detection of presenilin-1 (PS-1) gene mutation. The results show that given the same polymerase chain reaction (PCR) cycle num-ber, the ECL intensities from the digested and the undigested wild-type samples are nearly identical, but the difference in ECL intensities between the digested and the undigested mutant samples is distinctive. This detection technology connects PCR with ECL and allows a reliable discrimination between the wild-type and the mutant genes. | ZHU Debin, XING Da, SHEN Xingyan & YAN Guihong Institute of Laser Life Science, South China Normal University, Guang-zhou 510631, China Correspondence should be addressed to Xing Da (e-mail: xingda@ scnu.edu.cn) | 2003 | Chinese Science Bulletin2003，48，16： | 4 |

| 17 | Defect-rich titanium nitride nanoparticle with high microwaveacoustic conversion efficiency for thermoacoustic imaging-guided deep tumor therapy显示文摘Pulse microwave excite thermoacoustic(TA)shockwave to destroy tumor cells in situ.This has promising applications for precise tumor therapy in deep tissue.Nanoparticle(NP)with high microwave-acoustic conversion is the key to enhance the efficiency of therapy.In this study,we firstly developed defect-rich titanium nitride nanoparticles(TiN NPs)for pulse microwave excited thermoacoustic(MTA)therapy.Due to a large number of local structural defects and charge carriers,TiN NPs exhibit excellent electromagnetic absorption through the dual mechanisms of dielectric loss and resistive loss.With pulsed microwave irradiation,it efficiently converts the microwave energy into shockwave via thermocavitation effect,achieving localized mechanical damage of mitochondria in the tumor cell and yielding a precise antitumor effect.In addition to the therapeutic function,the NP-mediated TA process also generates images that provide valuable information,including tumor size,shape,and location for treatment planning and monitoring.The experimental results showed that the TiN NPs could be efficiently accumulated in the tumor via intravenous infusion.With the deep tissue penetration characteristics of microwave,the proposed TiN-mediated MTA therapy effectively and precisely cures tumors in deep tissue without any detectable side effects.The results indicated that defect-rich TiN NPs are promising candidates for tumor therapy. | Zhujun Wu Fanchu Zeng Le Zhang Shuxiang Zhao Linghua Wu Huan Qin Da Xing | 2021 | Nano Research2021，14，8： | 4 |
| 18 | Synchronous detection of glutathione/hydrogen peroxide for monitoring redox status in vivo with a ratiometric upconverting nanoprobe显示文摘Cellular redox status presents broad implications with diverse physiological and pathological processes. Simultaneous detection of both the oxidative and reductive species of redox couples, especially the most representative pair glutathione/hydrogen peroxide (GSH/H2O2), is crucial to accurately map the cellular redox status. However, it still remains challenging to synchronously detect GSH/H2O2 in vivo due to lack of a reliable measuring tool. Herein, a ratiometric nanoprobe (UCNP-TB) possessing simultaneous delectability of GSH/H2O2 is established based on a multi-spectral upconverti ng nano phosphor (UCNP-OA) as the lumin esce nee res onance energy tran sfer (LRET) donor and two dye molecules as the acceptors, including a GSH-sensitive dye (TCG) and a H2O2-sensitive dye (BCH). With the as-prepared UCNP-TB, real-time and synchronous monitoring the variation of GSH and H2O2 in vitro and in living mice can be achieved using the ratio of the upcon versi on lumin esce nee (UCL) at 540 and 650 nm to that at 800 nm as the detecti on sign al, respectively, providi ng highly inhere nt reliability of the sensing results by self-calibrati on. Moreover, the nan oprobe is capable of mappi ng the redox status within the drug-resista nt tumor and the drug-induced hepatotoxic liver via ratiometric UCL imaging. Thus, this nan oprobe would provide a reliable tool to elucidate the redox state in vivo. | Judun Zheng Yunxia Wu Da Xing Tao Zhang | 2019 | Nano Research2019，12，4： | 3 |
| 19 | Sensitive monitoring of RNA transcription levels using a graphene oxide fluorescence switch显示文摘Catalytic transfer of genetic information from DNA to RNA is very important in life activities. The unconventional RNA transcription level may be related to the source of genetic diseases. At present, conventional methods for detection of RNA transcripts usually involve cumbersome preparative steps, or require sophisticated laboratory equipments. In this study, we presented a rapid, sensitive nano-detection platform for monitoring of RNA transcript levels. T7 RNA polymerase transcription reaction is employed as the example to test the feasibility of this method. In this design, in vitro synthesized RNA products can be hybridized to the FAM labeled single strand DNA (ssDNA) probes which can be adsorbed onto the graphene oxide (GO) surface. Using GO as the fluorescence switch, excellent capacity of the signal-on fluorescence platform for detection of RNA transcripts level is demonstrated. Transcription levels sensing with this nano-platform achieved a sensitivity of 5 pmol/L transcription template. It is antici- pated that current developed RNA transcript nano-detection mode has the potential to be an alternative to the conventional RNA transcript detection methods. | ZHOU XiaoMing LIAO YuHui XING Da | 2013 | Chinese Science Bulletin2013，58，21： | 3 |
| 20 | Effect of long-term fertilization on soil nitrate distribution显示文摘A thirteen years long term field fertilizer experiment was conducted to monitor the effect of different fertilization on soil nitrate distribution. The results showed: (1) Applying relative excessive N fertilizer could result large quantities of NO - 3 residue and NO - 3 movement downward in soil profiles; amending phosphate fertilizer or organic manure with nitrogen fertilizer together could significantly improve the status of NO - 3 leaching downward due to the balanced uptake of nutrients by crops. (2) Appropriate amounts of nitrogen fertilizer which was equal or smaller than the optimal fertilization rate could not result in more NO - 3 leaching in Northern China. (3) Precipitation influenced the amounts and depth of soil NO\+-\-3 leaching: NO - 3 could move to 80 cm depth or below at autumn or at the next spring when rainfall was higher during the rainy season through July to September in North China. | GUO Li ping *, ZHANG Fu suo, WANG Xing ren, MAO Da ru, CHEN Xin ping (Department of Plant Nutrition, China Agricultural University, Beijing 100094, China.
