| 2 | Identification of various food residuals on denim based on hyperspectral imaging system and combination optimal strategy显示文摘As the science and technology develop,crime methods and scenes have become increasingly complex and diverse.Trace evidence analysis has become amore and more important criminal investigation technology and liquid is the main form of trace evidence.Food can provide not only energy,but clues to solve crimes.In this study,we build a hyperspectral imaging system to detect liquid residue traces,including apple juice,coffee,cola,milk and tea,on denims with light,middle and dark colors.The obtained hyperspectral images are first subjected to spectral calibration and hyperspectral data pretreatment.Subsequently,Partial Least Squares(PLS)is applied to select the informative wavelengths from the preprocessed spectra.For modeling phase,the combination optimal strategy,support vector machine(SVM)combined with random forest(RF),is developed to establish classification models.The experimental results demonstrate that the combination optimal model can achieve TPR,FPR,Precision,Recall,F1,and AUC of 83.5%,2.30%,79.7%,83.5%,81.6%,and 94.7%for classifying fabrics contaminated by various food residuals.With respect to the classification of liquid and fabric types,the combination optimalmodel also yields satisfactory classification performance.In future work,wewill expand the types of liquid,and make appropriate adjustment to algorithms for improving the robustness of classification models.This research may play a positive role in the construction of a harmonious society. | Yuzhen Chen Ziyi Xu Wencheng Tang Menghan Hu Douning Tang Guangtao Zhai Qingli Li | 2021 | Artificial Intelligence in Agriculture2021，，1： | 2 |
| 3 | PCA-U-Net based breast cancer nest segmentation from microarray(jj)hyperspectral images显示文摘The incidence of breast cancer is tending younger globally,and tumor development,clinical treatment,and prognosis are largely influenced by histopathological diagnosis.For diagnosed patients,the distinction between the cancer nests and normal tissue is the basis of breast cancer treatment.Microscopic hyperspectral imaging technology has shown its potential in auxiliary pathological examinations due to the superior imaging modality and data characteristics.This paper presents a method for cancer nest segmentation from hyperspectral images of breast cancer tissue microarray samples.The scheme combines the strengths of the U-Net neural network and unsupervised principal component analysis,which reduces the amount of calculation and improves the recognition accuracy.The experimental accuracy of cancer nest segmentation reaches 87.14%.Furthermore,a set of quantitative pathological characteristic parameters reflects the degree of breast cancer lesions from multiple angles,providing a relatively comprehensive reference for the pathologist’s diagnosis.In-depth exploration of the combined development of deep learning and microscopic hyperspectral imaging technology is worthy to promote efficient diagnosis of breast tumors and concern for human health. | Jiansheng Wang Yan Wang Xiang Tao Qingli Li Li Sun Jiangang Chen Mei Zhou Menghan Hu Xiufeng Zhou | 2021 | Fundamental Research2021，1，5： | 1 |
| 4 | Multi-stage anisotropic etching of two-dimensional heterostructures显示文摘Regarding the reverse process of materials growth,etching has been widely concerned to indirectly probe the growth kinetics,offering an avenue in governing the growth of two-dimensional(2D)materials.In this work,interface-driven anisotropic etching mode is demonstrated for the first time to be generally applied to 2D heterostructures.It is shown that the typical in-plane graphene and hexagonal boron nitride(h-BN)heterostructures follow a multi-stage etching behavior initiated first along the interfacial region between the two materials and then along edges of neighboring h-BN flakes and finally along central edges of hBN.By accurately tuning etching conditions in the chemical vapor deposition process,series of etched 2D heterostructure patterns are controllably produced.Furthermore,scaled formation of graphene and h-BN heterostructures arrays has been realized with full assist of as-proposed etching mechanism,offering a direct top-down method to make 2D orientated heterostructures with order and complexity.Detection of interface-driven multi-staged anisotropic etching mode will shed light on understanding growth mechanism and further expanding wide applications of 2D heterostructures. | Lin Li Jichen Dong Dechao Geng Menghan Li Wei Fu Feng Ding Wenping Hu Hui Ying Yang | 2022 | Nano Research2022，15，6： | 0 |

| 6 | Mechanism and prevention method of drill string uplift during shut-in after overflow in an ultra-deep well显示文摘Drill string will sustain large uplift force during the shut-in period after gas overflow in an ultra-deep well, and in serious case, it will run out of the wellhead. A calculation model of uplift force was established to analyze dynamic change characteristics of the uplift force of drill string during the shut-in period, and then a management procedure for the uplift risk during the shut-in period after gas overflow in the ultra-deep well was formed. Cross section method and pressure area method were used to analyze the force on drill string after shut-in of well, it was found that the source of uplift force was the 'fictitious force' caused by the hydrostatic pressure in the well. When the fictitious force is in the opposite direction to the gravity, it is the uplift force. By adopting the theory of annular multiphase flow, considering the effects of wellbore afterflow and gas slippage, the dynamic change of the pressure and fluid in the wellbore and the uplift force of drill string during the shut-in period were analyzed. The magnitude and direction of uplift force are related to the length of drill string in the wellbore and shut-in time, and there is the risk of uplift of drill string when the length of drill string in the wellbore is smaller than the critical drill string length or the shut in time exceeds the critical shut in time. A set of treatment method and process to prevent the uplift of drill string is advanced during the shut-in period after overflow in the ultra-deep well, which makes the risk management of the drill string uplift in the ultra-deep well more rigorous and scientific. | YIN Hu SI Menghan LI Qian JANG Hongwei DAI Liming | 2018 | Petroleum Exploration and Development2018，45，6： | 0 |
| 7 | Spatial-spectral identication of abnormal leukocytes based on microscopic hyperspectral imaging technology显示文摘Screening and diagnosing of abnormal Leukocytes are crucial for the diagnosis of immune diseases and Acute Lymphoblastic Leukemia(ALL).As the deterioration of abnormal leukocytes is mainly due to the changes in the chromatin distribution,which signicantly affects the absorption and reflection of light,the spectral feature is proved to be important for leukocytes classication and identication.This paper proposes an accurate identication method for healthy and abnormal leukocytes based on microscopic hyperspectral imaging(HSI)technology which combines the spectral information.The segmentation of nucleus and cytoplasm is obtained by the morphological watershed algorithm.Then,the spectral features are extracted and combined with the spatial features.Based on this,the support vector machine(SVM)is applied for classication ofve types of leukocytes and abnormal leukocytes.Compared with different classication methods,the proposed method utilizes spectral features which highlight the differences between healthy leukocytes and abnormal leukocytes,improving the accuracy in the classication and identication of leukocytes.This paper only selects one subtype of ALL for test,and the proposed method can be applied for detection of other leukemia in the future. | Xueqi Hu Jiahua Ou Mei Zhou Menghan Hu Li Sun Song Qiu Qingli Li Junhao Chu | 2020 | Journal of Innovative Optical Health Sciences2020，，2： | 0 |
| 8 | Exploration of Sponge System Design in Wetland Parks Based on Rainwater and Flood Control: A Case Study of Southern Anhui Province显示文摘Based on the background that wetland resources in China are under threat and urgently need to be protected,a series of rainwater and flood problems caused by urban construction is analyzed comprehensively,and the design and planning methods of wetland parks in response to rainwater and flood disasters caused by floods and heavy rainfall are explored.Southern Anhui with complex and variable terrain and frequent rainfall and flood disasters is selected as the research area,with Xuanzhou District of Xuancheng City as the main research object.The relationship between municipal drainage of urban park and water conservancy drainage is investigated from different sample selection,design samples,and design flow rates.Based on literature review and model building methods,an urban storm flood model suitable for typical wetland parks in southern Anhui is constructed after processing the survey data using Arc GIS,SWMM(storm water management model).On this basis,a methodology and principles for designing a sponge system of wetland park based on rainwater and flood control are proposed,including technical measures such as rainwater collection,retention,and purification.This paper provides certain research results in design schemes,effect evaluations,ecological and social benefits,and useful suggestions and solutions for urban stormwater management and resilience development. | CAO Menghan GE Juan HU Yueyue ZHANG Yanwen LI Yinan | 2023 | Journal of Landscape Research2023，15，6： | 0 |
| 9 | Building energy efficiency and COVID-19 infection risk:Lessons from office room management显示文摘To prevent COVID-19 outbreaks,many indoor environments are increasing the volume of fresh air and running air conditioning systems at maximum power.However,it is essential to consider the comfort of indoor occupants and energy consumption simultaneously when controlling the spread of infection.In this study,we simulated the energy consumption of a three-storey office building for postgraduate students and teachers at a university in Beijing.Based on an improved Wells-Riley model,we established an infection risk-energy consumption model considering non-pharmaceutical interventions and human comfort.The infection risk and building energy efficiency under different room occupancy rates on weekdays and at weekends,during different seasons were then evaluated.Energy consumption,based on the real hourly room occupancy rate during weekdays was 43%–55%lower than energy consumption when dynamic room occupancy rate was not considered.If all people wear masks indoors,the total energy consumption could be reduced by 32%–45%and the proportion of energy used for ventilation for epidemic prevention and control could be reduced by 22%–36%during all seasons.When only graduate students wear masks in rooms with a high occupancy,total energy consumption can be reduced by 15%–25%.After optimization,compared with the strict epidemic prevention and control strategy(the effective reproductive number Rt=1 in all rooms),energy consumption during weekdays(weekends)in winter,summer and transition seasons,can be reduced by 45%(74%),43%(69%),and 55%(78%),respectively.The results of this study provide a scientific basis for policies on epidemic prevention and control,carbon emission peak and neutrality,and Healthy China 2030. | Nan Zhang Tingrui Hu Menghan Niu Baotian Chang Nhantumbo Palmira Elisa Peng Xue Ying Ji | 2023 | Building Simulation2023，16，8： | 0 |
| 10 | Excitatory somatostatin interneurons in the dentate gyrus drive a widespread seizure network in cortical dysplasia显示文摘Seizures due to cortical dysplasia are notorious for their poor prognosis even with medications and surgery,likely due to the widespread seizure network.Previous studies have primarily focused on the disruption of dysplastic lesions,rather than remote regions such as the hippocampus.Here,we first quantified the epileptogenicity of the hippocampus in patients with late-stage cortical dysplasia.We further investigated the cellular substrates leading to the epileptic hippocampus,using multiscale tools including calcium imaging,optogenetics,immunohistochemistry and electrophysiology.For the first time,we revealed the role of hippocampal somatostatin-positive interneurons in cortical dysplasia-related seizures.Somatostatin-positive were recruited during cortical dysplasia-related seizures.Interestingly,optogenetic studies suggested that somatostatin-positive interneurons paradoxically facilitated seizure generalization.By contrast,parvalbumin-positive interneurons retained an inhibitory role as in controls.Electrophysiological recordings and immunohistochemical studies revealed glutamate-mediated excitatory transmission from somatostatin-positive interneurons in the dentate gyrus.Taken together,our study reveals a novel role of excitatory somatostatin-positive neurons in the seizure network and brings new insights into the cellular basis of cortical dysplasia. | Yang Zheng Cenglin Xu Jinyi Sun Wenjie Ming Sijie Dai Yuying Shao Xiaoyun Qiu Menghan Li Chunhong Shen Jinghong Xu Fan Fei Jiajia Fang Xuhong Jiang Guoqing Zheng Weiwei Hu Yi Wang Shuang Wang Meiping Ding Zhong Chen | 2023 | Signal Transduction and Targeted Therapy2023，8，6： | 0 |
| 11 | Peroxisome proliferator-activated receptors gama ameliorates liver fibrosis in non-alcoholic fatty liver disease by inhibiting TGF-β/Smad signaling activation显示文摘Background:Nonalcoholic fatty liver disease(NAFLD)is a chronic condition characterized by a progressive decline in liver function,leading to disruptions in liver integrity and metabolic function,resulting in lipid deposition and excessive accumulation of extracellular matrix(ECM).The pathogenesis of NAFLD is complex and not yet fully understood,contributing to the absence of specific therapeutic strategies.Peroxisome proliferator-activated receptor gamma(PPARγ)is a ligand-activated transcription factor pivotal in regulating lipid and glucose metabolism.However,the impacts of PPARγon NAFLD remains insufficiently explored.Thus,this study aimed to investigate the role of PPARγin NAFLD and its underlying molecular mechanisms.Methods:Chemical detection kits were utilized to quantify collagen content,alanine aminotransferase(ALT),and aspartate aminotransferase(AST)level variations.Quantitative real-time polymerase chain reaction(qRT-PCR)was employed to assess alterations in extracellular matrix-related genes and inflammatory response genes in liver tissue and HepG2 cells,while western blotting was conducted to analyze the levels of both PPARγand the TGF-β/Smad signaling pathway.Results:Our findings unveiled significantly reduced PPARγexpression in a rat model of NAFLD,leading to subsequent activation of the TGF-β/Smad signaling pathway.Furthermore,PPARγactivation effectively mitigated NAFLD progression by inhibiting inflammation and fibrosis-related gene expression and collagen production.On a cellular level,PPARγactivation was found to inhibit the expression of extracellular matrix-related genes such as matrix metalloproteinase 2(MMP2)and matrix metalloproteinase 9(MMP9),along with inflammatory response genes interleukin(IL)-1βand IL-6.Additionally,PPARγactivation led to a significant decrease in the levels of ALT and AST.At the molecular level,PPARγnotably down-regulated the TGF-β/Smad signaling pathway,which is known to promote liver fibrosis.Conclusion:These groundbreaking findings underscore PPARγactivation as a promising therapeutic approach to delay NAFLD progression by targeting the TGF-β/Smad signaling pathway in hepatic cells.This highlights the potential of PPARγas a promising therapeutic target for NAFLD management in clinical settings. | Qingwei Zhang Wenjie Zhao Zeqi Sun Xinxin Dong Liwei Zhu Zhen Zhang Ximing Chen Yingying Hu Menghan Du Jiamin Li Yong Zhang | 2024 | Frigid Zone Medicine2024，4，1： | 0 |

| 15 | The composite phenotype analysis identifies potential concerted responses of physiological systems to high altitude exposure显示文摘Environmental stresses,such as temperature,disease and altitude could induce systematic changes of biological systems which manifests as concerted responses across multiple systems within a certain period of time[1].High altitude acclimatization(HAA)refers to a series of adaptive physiological responses to hypoxic stress. | Yi Li Meng Hao Zixin Hu Yanyun Ma Kun Wang Xiaoyu Liu Xianhong Yin Menghan Zhang Yi Wang Meng Liang Yuan Guo Lei Bao Shixuan Zhang Shiguan Le Chenyuan Wu Dayan Sun Yang Wei Fei Wu Rui Zhang Lingxian Zhu Hui Zhang Shuai jang Xingdong Chen Xiaofeng Wang Yao Zhang Longli Kang Wenyuan Duan Bin Qiao Jiucun Wang Li Jin | 2023 | National Science Review2023，10，5： | 0 |
| 16 | Auxiliary Diagnosis of Papillary Thyroid Carcinoma Based on Spectral Phenotype显示文摘Thyroid cancer,a common endocrine malignancy,is one of the leading death causes among endocrine tumors.The diagnosis of pathological section analysis suffers from diagnostic delay and cumbersome operating procedures.Therefore,we intend to construct the models based on spectral data that can be potentially used for rapid intraoperative papillary thyroid carcinoma(PTC)diagnosis and characterize PTC characteristics.To alleviate any concerns pathologists may have about using the model,we conducted an analysis of the used bands that can be interpreted pathologically.A spectra acquisition system was first built to acquire spectra of pathological section images from 91 patients.The obtained spectral dataset contains 217 spectra of normal thyroid tissue and 217 spectra of PTC tissue.Clinical data of the corresponding patients were collected for subsequent model interpretability analysis.The experiment has been approved by the Ethics Review Committee of the Wuhu Hospital of East China Normal University.The spectral preprocessing method was used to process the spectra,and the preprocessed signal respectively optimized by the first and secondary informative wavelengths selection was used to develop the PTC detection models.The PTC detection model using mean centering(MC)and multiple scattering correction(MSC)has optimal performance,and the reasons for the good performance were analyzed in combination with the spectral acquisition process and composition of the test slide.For model interpretable analysis,the near-ultraviolet band selected for modeling corresponds to the location of amino acid absorption peak,and this is consistent with the clinical phenomenon of significantly lower amino acid concentrations in PTC patients.Moreover,the absorption peak of hemoglobin selected for modeling is consistent with the low hemoglobin index in PTC patients.In addition,the correlation analysis was performed between the selected wavelengths and the clinical data,and the results show:the reflection intensity of selected wavelengths in normal cells has a moderate correlation with cell arrangement structure,nucleus size and free thyroxine(FT4),and has a strong correlation with triiodothyronine(T3);the reflection intensity of selected bands in PTC cells has a moderate correlation with free triiodothyronine(FT3). | Bailiang Zhao Yan Wang Menghan Hu Yue Wu Jiannan Liu Qingli Li Min Dai Wendell QSun Guangtao Zhai | 2023 | Phenomics2023，3，5： | 0 |
| 17 | Optical non-destructive techniques for small berry fruits: A review显示文摘Small berries including strawberry and blueberry are extensively consumed fruits with great economic values due to their characteristic flavor and appearance as well as potential health benefits.This review elaborated the optical non-destructive techniques viz.Vis-NIR spectroscopy,computer vision system,hyperspectral imaging,multispectral imaging,laser-induced method and thermal imaging,and their applications for quality and safety control of small berry fruits.The discussion regarding the photoacoustic technique,X-ray technique,Terahertz spectroscopy,odor imaging,micro-destructive testing and smart mobile terminal-based analyzer was also presented.Furthermore,we proposed our personal understanding of the technical challenges and further trends for these optical non-destructive techniques:1)owing to the relatively low detection limit,the so-called micro-destructive techniques may be alternative to the traditional non-destructive techniques in both practical and fundamental research;2)we suggest that the research articles like“collecting data first,and then modeling the relevant properties of agricultural products by machine learning”should be less produced in related fields.That's because such research methods are likely to be suspected of“cheating”.It is recommended that some modeling competitions can be carried out in the agricultural engineering field to avoid or reduce the“cheating”model. | Shuping Li Hongpei Luo Menghan Hu Miao Zhang Jianlin Feng Yangtai Liu Qingli Dong Baolin Liu | 2019 | Artificial Intelligence in Agriculture2019，，2： | 0 |
