3A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM.Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON 2020Science China Earth Sciences2020,63,8:7
4Anti-P-selectin lectin-EGF domain monoclonal antibody inhibits the maturation of human immature dendritic cells显示文摘Dendritic cells(DCs) are professinal antigen-presenting cells with the ability to initiate primary Tcell responses. While it iswell known that inflammatory stimuli induce the functional maturation of immature DCs, whether adhesion molecule selectins regulate DCmaturation is poorly understood. Using anti-P-selectin lectin-EGF domain monoclonal antibody (PsL-EGFmAb) that blocks the adhesionof P-, E-, and L-selectin, we demonstrate herein that selectins play important role in stimulating functional maturation of immature DCs.Immature DCs are generated from human cord blood CD34+hematopoietic stem/progenitor cells that were cultured in the presence of stemcell factor, Fms-like tyrosine-kinase-3 ligand, granulocyte-macrophage colony stimulating factor, and transform growth factor-β1. Whenstimulated with tumor necrosis factor-alpha(TNF-α), immature DCs differentiated into mature DCs, producing increased levels of costim-ulatory molecules and interleukin (IL)-12 and obtaining the ability to potently activate naive Tcells. Interestingly, in contrast to matureDCs derived from TNF-α-induced immature DC cultures without PsL-EGFmAb, immature DCs treated with PsL-EGFmAb for7 days werecompletely blocked their maturation, as evidenced by decreased expression of costimulatory molecules CD80, CD86, and CD83, inhibi-ted production of IL-12, and inability to activate naive Tcellsin vitro. Thus, blockade of selectins using PsL-EGFmAb will prove to bea valuable tool for the study of the molecuar mechanisms of DC maturation, as well as for the prevention and treatment of DC-mediated au-toimmunity.Tong Zhou Yanyu Zhang Guizhi Sun Yumei Zhang Dongqing Zhang Yapeng Zhao Nan Chen 2006上海交通大学学报(医学版)2006,26,5:5
5Processing,Quality,Safety,and Acceptance of Meat Analogue Products显示文摘Rapid global population growth has caused an increasing need for products containing protein.Meat products are the most common high-protein food source,but impact the environment,cause animal welfare issues,and raise public health concerns.Consumer health and food safety are paramount to the food industry.Both the scientists and food industry are actively seeking plant proteins to substitute for animal-sourced proteins.Plant proteins have a well-balanced amino acid composition,and exhibit great potential for replacing meat via the development of healthy,high-protein,low-saturated fat,cholesterol-free,and nutritionally similar meat-like products.Generally,meat analogue formulations are specially designed and processing conditions are optimized to obtain the texture and bite of real animal meat.This article focuses on plant-based meat analogues,and covers aspects regarding processing,products,quality,and nutritional and structural modifications.Product safety consciousness and consumer acceptance are also discussed.Challenges and perspectives for future research concerning nonmeat products are presented.Cuixia Sun Jiao Ge Jun He Renyou Gan Yapeng Fang 2021Engineering2021,7,5:4
6Force-controlled Compensation Scheme for P-Q Valve-controlled Asymmetric Cylinder used on Hydraulic Quadruped Robots显示文摘Under the requirement of the force controller of hydraulic quadruped robots,the goal of this work is to accurately track the force commands at the level of the hydraulic drive unit.The main contribution focuses on the development of a force-controlled compensation scheme,which is specifically aimed at the key issues affecting the hydraulic quadrupedal locomotion.With this idea,based on a P-Q valve-controlled asymmetric cylinder,we first establish a mathematical model for the hydraulic drive unit force control system.With the desired force commands,a force feed-forward algorithm is presented to improve the dynamic performance of the system.Meanwhile,we propose a disturbance compensation algorithm to reduce the influence induced by external disturbances due to foot-ground impacts.Afterwards,combining with a variable gain PI controller,a series of experiments are implemented on a force control performance test platform to verify the proposed scheme.The results demonstrate that the force-controlled compensation scheme has the ability to notably improve the force tracking accuracy,reduce the response time and redundant force.Yapeng Shi Mantian Li Fusheng Zha Lining Sun Wei Guo Cong Ma Zhibin Li 2020Journal of Bionic Engineering2020,17,6:1

8A high-accuracy DCO with hybrid architecture显示文摘In this paper, a novel hybrid digital-controlled oscillator(DCO) is proposed, which is used to improve the accuracy of the all-digital clock generator without reference source. The DCO with hybrid architecture consists of two parts: DCO_high and DCO_low. The DCO_high decides the coarse output frequency of DCO, and adopts the cascade structure to decrease the area. The DCO_low adopts the chain structure with three-state buffer, and decides the fine output frequency of DCO. Compared with traditional cascade DCO, the proposed hybrid DCO features higher precision with less inherent delay. Therefore the clock generator can tolerate process, voltage and temperature(PVT) variation and meet the needs of different conditions. The DCO is designed in SMIC 180 nm CMOS process with 0.021 mm^2 chip area. The output frequency is adjusted from 15–120 MHz. The frequency error is less than 0.83% at 25 MHz with 1.6–1.8 V supply voltage and 0–80℃ temperature variations in TT, FF,SS corners.Yapeng Sun Huidong Zhao Shushan Qiao Yong Hei Fuhai Zhang 2017Journal of Semiconductors2017,38,7:0
9An Improved Gorilla Troops Optimizer Based on Lens Opposition-Based Learning and Adaptive β-Hill Climbing for Global Optimization显示文摘Gorilla troops optimizer(GTO)is a newly developed meta-heuristic algorithm,which is inspired by the collective lifestyle and social intelligence of gorillas.Similar to othermetaheuristics,the convergence accuracy and stability of GTOwill deterioratewhen the optimization problems to be solved becomemore complex and flexible.To overcome these defects and achieve better performance,this paper proposes an improved gorilla troops optimizer(IGTO).First,Circle chaotic mapping is introduced to initialize the positions of gorillas,which facilitates the population diversity and establishes a good foundation for global search.Then,in order to avoid getting trapped in the local optimum,the lens opposition-based learning mechanism is adopted to expand the search ranges.Besides,a novel local search-based algorithm,namely adaptiveβ-hill climbing,is amalgamated with GTO to increase the final solution precision.Attributed to three improvements,the exploration and exploitation capabilities of the basic GTOare greatly enhanced.The performance of the proposed algorithm is comprehensively evaluated and analyzed on 19 classical benchmark functions.The numerical and statistical results demonstrate that IGTO can provide better solution quality,local optimumavoidance,and robustness compared with the basic GTOand five other wellknown algorithms.Moreover,the applicability of IGTOis further proved through resolving four engineering design problems and training multilayer perceptron.The experimental results suggest that IGTO exhibits remarkable competitive performance and promising prospects in real-world tasks.Yaning Xiao Xue Sun Yanling Guo Sanping Li Yapeng Zhang Yangwei Wang 2022Computer Modeling in Engineering & Sciences2022,,5:0
10Effects of the vegetative propagation method on juvenility in Robinia pseudoacacia L.显示文摘Vegetative propagation is an important method of reproduction and rejuvenation in forestry.The growth and development of asexually propagated trees are influenced by the age and position of the propagule on the plant,effects referred to as cyclophysis and topophysis,respectively.Due to the long lifespans and large body sizes of woody trees,the selection of propagules is critically important.Here,we used three vegetative propagation methods(shoot cutting,root sprouting,and root cutting)to study the effect of different regeneration methods on juvenility of the resulting black locust plants,with seed-derived seedlings used as a control.Most characteristics of plantlets generated by rootsprouting were similar to those of seed-derived seedlings,including leaf traits and leaf anatomical structure.However,there were significant differences between the plantlets derived from shoot-cuttings and seedlings from seeds.Furthermore,the data showed that some of these agerelated small RNAs and genes differed in expression among propagation methods and between plantlets/seedlings and mature trees.These agerelated small RNAs,genes,and transcription factors may be used as molecular markers of juvenility and phase transitions in black locust.Our results provide useful information for the optimal propagation of woody trees and for further research into the mechanisms of root regeneration.Jie Liu Zijie Zhang Yapeng Li Juan Han Huayu Si Yueqi Mi Shaoming Wang Xiaoning Wei Hao Yang Yuhan Sun Yun Li 2022Forestry Research2022,2,1:0
