2Wood defect detection method with PCA feature fusion and compressed sensing显示文摘We used principal component analysis(PCA) and compressed sensing to detect wood defects from wood plate images. PCA makes it possible to reduce data redundancy and feature dimensions and compressed sensing, used as a classifier, improves identification accuracy. We extracted 25 features, including geometry and regional features, gray-scale texture features, and invariant moment features, from wood board images and then integrated them using PCA, and selected eight principal components to express defects. After the fusion process, we used the features to construct a data dictionary, and realized the classification of defects by computing the optimal solution of the data dictionary in l_1 norm using the least square method. We tested 50 Xylosma samples of live knots, dead knots, and cracks. The average detection time with PCA feature fusion and without were 0.2015 and 0.7125 ms,respectively. The original detection accuracy by SOM neural network was 87 %, but after compressed sensing, it was 92 %.Yizhuo Zhang Chao Xu Chao Li Huiling Yu Jun Cao 2015Journal of Forestry Research2015,26,3:17
3Recognition of wood surface defects with near infrared spectroscopy and machine vision显示文摘To improve the accuracy in recognizing defects on wood surfaces,a method fusing near infrared spectroscopy(NIR)and machine vision was examined.Larix gmelinii was selected as the raw material,and the experiments focused on the ability of the model to sort defects into four types:live knots,dead knots,pinholes,and cracks.Sample images were taken using an industrial camera,and a morphological algorithm was applied to locate the position of the defects.A portable near infrared spectrometer(900–1800 nm)collected the spectra of these positions.In addition,principal component analysis was utilized on these variables from spectral information and principal component vectors were extracted as the inputs of the model.The results show that a back propagation neural network model exhibited better discrimination accuracy of 92.7%for the training set and 92.0%for the test set.The research reveals that the NIR fusing machine vision is a feasible tool for detecting defects on board surfaces.Huiling Yu Yuliang Liang Hao Liang Yizhuo Zhang 2019Journal of Forestry Research2019,30,6:16
4Assessment of coral bleaching using symbiotic zooxanthellae density and satellite remote sensing data in the Nansha Islands,South China Sea显示文摘Coral bleaching,characterized by a significant loss of symbiotic zooxanthellae,is the primary cause of mass coral mortality and reef degradation throughout the world.The characteristics,processes,and resistance of corals to bleaching varies significantly and is dependent on environmental conditions.We documented a mass coral bleaching event in June 2007 at the Meiji and Zhubi Reefs,Nansha Islands (NS),South China Sea using ecological surveys and measurement of coral zooxanthellae density and sea surface temperatures (SST).More than 35 species of corals (between 0-20 m in depth) were bleached.These bleached corals accounted for 15.6% of total corals in the investigated quadrats.The branching corals Pocillopora and Acropora were the most vulnerable species whereas the massive corals Porites and Favia were more tolerant of the high SSTs.Surprisingly,we found no evidence of bleaching in Agariciidae corals suggesting that this family is resistant to thermal stresses.The bleached corals had lost 72%-90% of their symbiotic zooxanthellae.Furthermore,corals that had no visual signs of bleaching had also lost 31%-53% of their zooxanthellae suggesting that most corals were experiencing the early stage of bleaching.The monthly mean SST during June 2007 was 30.8°C,the highest since 1998.Based on measurements of SST and the Hotspots and DHW data (NOAA),we conclude that it the extremely high SSTs triggered this coral bleaching event.Our results suggest that the previously accepted temperature thresholds used to predict coral bleaching based on satellite data are likely to underestimate the extent and intensity of coral bleaching,at least in the NS.LI Shu,YU KeFu,CHEN TianRan,SHI Qi & ZHANG HuiLing CAS Key Laboratory of Marginal Sea Geology,South China Sea Institute of Oceanology,Chinese Academy of Sciences Guangzhou 510301,China 2011Chinese Science Bulletin2011,56,10:15
5SURFACE STRESS EFFECT IN MECHANICS OF NANOSTRUCTURED MATERIALS显示文摘This review article summarizes the advances in the surface stress effect in mechanics of nanostructured elements,including nanoparticles,nanowires,nanobeams,and nanofilms,and heterogeneous materials containing nanoscale inhomogeneities.It begins with the fundamental formulations of surface mechanics of solids,including the definition of surface stress as a surface excess quantity,the surface constitutive relations,and the surface equilibrium equations.Then,it depicts some theoretical and experimental studies of the mechanical properties of nanostructured elements,as well as the static and dynamic behaviour of cantilever sensors caused by the surface stress which is influenced by adsorption.Afterwards,the article gives a summary of the analytical elasto-static and dynamic solutions of a single as well as multiple inhomogeneities embedded in a matrix with the interface stress prevailing.The effect of surface elasticity on the diffraction of elastic waves is elucidated.Due to the difficulties in the analytical solution of inhomogeneities of complex shapes and configurations,finite element approaches have been developed for heterogeneous materials with the surface stress.Surface stress and surface energy are inherently related to crack propagation and the stress field in the vicinity of crack tips.The solutions of crack problems taking into account surface stress effects are also included.Predicting the effective elastic and plastic responses of heterogeneous materials while taking into account surface and interface stresses has received much attention.The advances in this topic are inevitably delineated.Mechanics of rough surfaces appears to deserve special attention due to its theoretical and practical implications.Some most recent work is reviewed.Finally,some challenges are pointed out.They include the characterization of surfaces and interfaces of real nanomaterials,experimental measurements and verification of mechanical parameters of complex surfaces,and the effects of the physical and chemical processes on the surface properties,etc.Jianxiang Wang Zhuping Huang Huiling Duan Shouwen Yu Xiqiao Feng Gangfeng Wang Weixu Zhang Tiejun Wang 2011Acta Mechanica Solida Sinica2011,24,1:11
6A LysM Receptor Heteromer Mediates Perception of Arbuscular Mycorrhizal Symbiotic Signal in Rice显示文摘Symbiotic microorganisms improve nutrient uptake by plants.To initiate mutualistic symbiosis with arbus-cular mycorrhizal(AM)fungi,plants perceive Myc factors,including lipochitooligosaccharides(LCOs)and short-chain chitooligosaccharides(CO4/CO5),secreted by AM fungi.However,the molecular mechanism of Myc factor perception remains elusive.In this study,we identified a heteromer of LysM receptor-like kinases consisting of OsMYR1/OsLYK2 and OsCERK1 that mediates the perception of AM fungi in rice.CO4 directly binds to OsMYR1,promoting the dimerization and phosphorylation of this receptor complex.Compared with control plants,Osmyr1 and Oscerk1 mutant rice plants are less sensitive to Myc factors and show decreased AM colonization.We engineered transgenic rice by expressing chimeric receptors that respectively replaced the ectodomains of OsMYR1 and OsCERK1 with those from the homologous Nod factor receptors MtNFP and MtL YK3 of Medicago truncatula.Transgenic plants displayed increased cal-cium oscillations in response to Nod factors compared with control rice.Our study provides significant mechanistic insights into AM symbiotic signal perception in rice.Expression of chimeric Nod/Myc recep-tors achieves a potentially important step toward generating cereals that host nitrogen-fixing bacteria.Jiangman He Chi Zhang Huiling Dai Huan Liu Xiaowei Zhang Jun Yang Xi Chen Yayun Zhu Dapeng Wang Xiaofeng Qi Weichao Li Zhihui Wang Guoyong An Nan YU Zuhua He Yong-Fei Wang Youli Xiao Peng Zhang Ertao Wang 2019Molecular Plant2019,12,12:9

8Soft measurement of wood defects based on LDA feature fusion and compressed sensor images显示文摘We proposed a detection method for wood defects based on linear discriminant analysis(LDA) and the use of compressed sensor images. Wood surface images were captured, using a camera Oscar F810C IRF camera,and then the image segmentation was performed, and the defect features were extracted from wood board images. To reduce the processing time, LDA algorithm was used to integrate these features and reduce their dimensions. Features after fusion were used to construct a data dictionary and a compressed sensor was designed to recognize the wood defects types. Of the three major defect types, 50 images live knots, dead knots, and cracks were used to test the effects of this method. The average time for feature fusion and classification was 0.446 ms with the classification accuracy of 94%.Chao Li Yizhuo Zhang Wenjun Tu Cao Jun Hao Liang Huiling Yu 2017Journal of Forestry Research2017,28,6:6

12Deep brain–machine interfaces:sensing and modulating the human deep brain显示文摘Different from conventional brain–machine interfaces that focus more on decoding the cerebral cortex,deep brain–machine interfaces enable interactions between external machines and deep brain structures.They sense and modulate deep brain neural activities,aiming at function restoration,device control and therapeutic improvements.In this article,we provide an overview of multiple deep brain recording and stimulation techniques that can serve as deep brain–machine interfaces.We highlight two widely used interface technologies,namely deep brain stimulation and stereotactic electroencephalography,for technical trends,clinical applications and brain connectivity research.We discuss the potential to develop closed-loop deep brain–machine interfaces and achieve more effective and applicable systems for the treatment of neurological and psychiatric disorders.Yanan Sui Huiling Yu Chen Zhang Yue Chen Changqing Jiang Luming Li 2022National Science Review2022,9,10:3
13A rapid, automated flaw segmentation method using morphological reconstruction to grade wood flooring显示文摘Region-Growing Algorithms(RGAs) are used to grade the quality of manufactured wood flooring. Traditional RGAs are hampered by problems of long segmentation time and low inspection accuracy caused by neighborhood search. We used morphological reconstruction with the R component to construct a novel flaw segmentation method. We initially designed two template images for low and high thresholds, and these were used for seed optimization and inflation growth, respectively. Then the extraction of the flaw skeleton from the low threshold image was realized by applying the erosion termination rules. The seeds in the flaw skeleton were optimized by the pruning method. The geodesic inflection was applied by the high threshold template to realize rapid growth of the flaw area in the floor plate, and region filling and pruning operations were applied for margin optimization. Experiments were conducted on 512×512, 256×256 and 128×128 pixel sizes, respectively. The 256×256 pixel size proved superior in time-consumption at 0.06 s with accuracy of 100%. But with the region-growing method the same process took 0.22 s with accuracy of 70%. Compared with RGA, our proposed method can realize more accurate segmentation, and the speed and accuracy of segmentation can satisfy the requirements for on-line grading of wood flooring.Yizhuo Zhang Sijia Liu Jun Cao Chao Li Huiling Yu 2014Journal of Forestry Research2014,25,4:3
14Intelligent lesion blood–brain barrier targeting nano-missiles for Alzheimer's disease treatment by anti-neuroinflammation and neuroprotection显示文摘The treatment of Alzheimer's disease(AD)is one of the most difficult challenges in neurodegenerative diseases due to the insufficient blood‒brain barrier(BBB)permeability and unsatisfactory intra-brain distribution of drugs.Therefore,we established an ibuprofen and FK506 encapsulated drug co-delivery system(Ibu&FK@RNPs),which can target the receptor of advanced glycation endproducts(RAGE)and response to the high level of reactive oxygen species(ROS)in AD.RAGE is highly and specifically expressed on the lesion neurovascular unit of AD,this property helps to improve targeting specificity of the system and reduce unselective distribution in normal brain.Meanwhile,these two drugs can be specifically released in astrocytes of AD lesion in response to high levels of ROS.As a result,the cognition of AD mice was significantly improved and the quantity of Aβplaques was decreased.Neurotoxicity was also alleviated with structural regeneration and functional recovery of neurons.Besides,the neuroinflammation dominated by NF-κB pathway was significantly inhibited with decreased NF-κB and IL-1βin the brain.Overall,Ibu&FK@RNPs can efficiently and successively target diseased BBB and astrocytes in AD lesion.Thus it significantly enhances intracephalic accumulation of drugs and efficiently treats AD by anti-neuroinflammation and neuroprotection.Xueqin He Xiaorong Wang Lianyi Yang Zhihang Yang Wenqi Yu Yazhen Wang Rui Liu Meiwan Chen Huile Gao 2022Acta Pharmaceutica Sinica B2022,12,4:3
15Needling at the Waiguan (SJ5) in healthy limbs deactivated functional brain areas in ischemic stroke patients A functional magnetic resonance imaging study显示文摘Deactivation is common in cerebral functional imaging. However, the physiological mechanisms responsible for this phenomenon remain poorly understood. The present study analyzed 12 ischemic stroke patients, who were randomly assigned to two groups: one group underwent sham needling and true needling at the Waiguan (SJ 5) in the healthy upper limb and the other group underwent sham and true needling at a sham point. Functional magnetic resonance imaging results showed no activation points in brain tissues following needling at SJ 5. However, compared with sham needling at SJ 5, true needling at SJ 5 deactivated Broadmann 4, 6, 24, and 32 areas. In addition, compared to needling at the sham point, true needling at SJ 5 deactivated bilateral hypothalamus. Results demonstrated that SJ 5 needling in the healthy upper limb resulted in specific directional brain action, as manifested by deactivation of cerebral areas related to motor (Broadmann 4 and 6), emotion (hypothalamus), and cognition (Broadmann 24, 32).Yong Huang Huiling Xiao Junqi Chen Shanshan Qu Yu Zheng Yangjia Lu Xinsheng Lai 2011Neural Regeneration Research2011,6,36:2
