| 3 | Ultrasensitive skin‐like wearable optical sensors based on glass micro/nanofibers显示文摘Electronic skin,a class of wearable electronic sensors that mimic the functionalities of human skin,has made remarkable success in applications including health monitoring,human-machine interaction and electronic-biological interfaces.While electronic skin continues to achieve higher sensitivity and faster response,its ultimate performance is fundamentally limited by the nature of low-frequency AC currents.Herein,highly sensitive skin-like wearable optical sensors are demonstrated by embedding glass micro/nanofibers(MNFs)in thin layers of polydimethylsiloxane(PDMS).Enabled by the transition from guided modes into radiation modes of the waveguiding MNFs upon external stimuli,the skin-like optical sensors show ultrahigh sensitivity(1870 k·Pa^-1),low detection limit(7 mPa)and fast response(10μs)for pressure sensing,significantly exceeding the performance metrics of state-of-the-art electronic skins.Electromagnetic interference(EMI)-free detection of high-frequency vibrations,wrist pulse and human voice are realized.Moreover,a five-sensor optical data glove and a 2×2-MNF tactile sensor are demonstrated.These initial results pave the way toward a new category of optical devices ranging from ultrasensitive wearable sensors to optical skins. | Lei Zhang Jing Pan Zhang Zhang Hao Wu Ni Yao Dawei Cai Yingxin Xu Jin Zhang Guofei Sun Liqiang Wang Weidong Geng Wenguang Jin Wei Fang Dawei Di Limin Tong | 2020 | Opto-Electronic Advances2020，3，3： | 12 |

| 7 | Preparation and in vitro-in vivo evaluation of intestinal retention pellets of Berberine chloride to enhance hypoglycemic and lipid-lowing efficacy显示文摘Berberine chloride(BBR) is a pharmacokinetic profile of drug with poor bioavailability but good therapeutic efficacy,which is closely related to the discovery of BBR intestinal target.The major aim of this paper is to develop BBR intestinal retention type sustained-release pellets and evaluate their in vivo and in vitro behaviors base on the aspect of local action on intestinal tract. Here,wet milling technology is used to improve dissolution and dissolution rate of BBR by decreasing the particle size and increasing the wettability. The pellets are prepared by liquid layer deposition technology,and then the core pellets are coated with Eudragit~?L30 D-55 and Eudragit~?NE30 D aqueous dispersion. The prepared pellets show high drug loading capacity,and the drug loading up to 93%. Meanwhile,it possesses significant sustained drug release effect in purified water which is expected to improve the pharmacokinetic behavior of BBR. The pharmacokinetics results demonstrate that the halflife of BBR was increased significantly from 24 h to 36 h and the inter-and intra-subject variability are decreased compared to commercial BBR tablets. The retention test results indicate that the pellet size and Eudragit~?NE30 D plays an important role in retention time of the pellet,and it is found that the pellets with small particle size and high Eudragit~?NE30 D coating content can stay longer in the intestine than the pellets with large particle size. All in all,BBR intestinal retention type pellets are prepared successfully in this study,and the pellets show satisfactory in vivo and in vitro behaviors. | Guofei Li Mingming Zhao Xianying Su Lin Song Limei Zhao | 2019 | Asian Journal of Pharmaceutical Sciences2019，14，5： | 5 |
| 8 | Effects of meteorological factors on the defoliation dynamics of the larch caterpillar(Dendrolimus superans Butler)in the Great Xing’an boreal forests显示文摘Larch caterpillars are widely distributed in the Great Xing’an boreal forests;however,the relationship between caterpillar defoliation dynamics and climatic factors is poorly understood.The aims of this study are to investigate the primary weather conditions that might influence forest defoliation and to identify the most important life stage of the larch caterpillar at which forest defoliation might be mitigated by incorporating more inhibitory influences from climatic factors.The life cycle of the larch caterpillar was partitioned into four stages and multiple linear regression and mixed effect models were combined with a relative weight analysis approach to evaluate the importance and influence of meteorological variables on defoliation dynamics.The results show that warmer temperatures in growing seasons and overwintering periods can increase the defoliation area,while rainy and humid growing seasons decrease the defoliation area.Total precipitation during the early instar larval period had the greatest power to explain the variance in defoliation dynamics and had a very strong inhibitory effect,followed by the accumulative temperatures of the late instar larval period which had a positive impact,and precipitation during the middle instar larval period which had a negative impact.Weather conditions during the early instar larval period had the greatest influence on the area defoliated and accounted for 40%of the explained variance.This study demonstrates that climatic warming and drying will increase the risk of larch caterpillar outbreaks in the Great Xing’an Mountains. | Lei Fang Yue Yu Guofei Fang Xu Zhang Zhijun Yu Xudong Zhang Ellen Crocker Jian Yang | 2021 | Journal of Forestry Research2021，32，6： | 3 |
| 9 | Molecular dynamics simulations of CH4 diffusion in kaolinite: influence of water content显示文摘Understanding the interaction of CH4 with kaolinite is significant for researchers in the fields of coalbed CH4 and shale gas.The diffusion behaviors of CH4 in kaolinite with water contents ranging from 0 to 5 wt% have been analyzed by molecular dynamics simulations.The results of the simulations indicate that CH4 molecules can jump between adjacent holes in the kaolinite matrix.CH4 diffusion coefficient was very low (3.28 × 10-9 m2/s) and increased linearly with the increasing of water content.As the water content decreased,the value of radial distribution function first peak between CH4 and oxygen was larger,meaning that with lower water content,the interaction energy between CH4 and oxygen in kaolinite is stronger.The interaction between CH4 and water is linearly positively correlated with water content,in contrast,the interaction energy between kaolinite and water as well as between kaolinite and CH4 decreased linearly with increasing water content.On the other hand,the diffusion of CH4 molecules adsorbed on the surfaces also can be accelerated by the fast diffusion of water molecules in the middle micropore of the kaolinite. | Bin Zhang Jianting Kang Tianhe Kang Guanxian Kang Guofei Zhao | 2019 | International Journal of Coal Science & Technology2019，6，4： | 3 |
| 10 | Corrosion Inhibition by Co-Immobilized Lysozyme and Lipase in Circulating Cooling Water System显示文摘The corrosion inhibition performance of co-immobilized lysozyme and lipase was investigated in a recirculating cooling water system. Four methods were carried out in co-immobilization, and the operating parameters were optimized by using the respond surface methodology(RSM). The corrosion inhibition performance of co-immobilized lipase and lysozyme was evaluated by weight loss measurements and electrochemical measurements. The results revealed that the optimal co-immobilization method should be the sequential immobilization of lysozyme and then lipase. The inhibition efficiency was 86.10% under the optimal co-immobilized conditions. Electrochemical data showed that co-immobilized lysozyme and lipase was a mixed-type inhibitor and the corrosion inhibition efficiency was 81%. | Liu Fang Lü Yucui Jiang Guofei Chen Xiaorui Sun Juan Zhao Chaocheng | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，2： | 3 |
| 11 | DFT study on the interaction of HCHO molecule with S-doped TiO_(2) (001) surface without and with water and oxygen molecules显示文摘The interactions of formaldehyde(HCHO)molecule with S-doped anatase TiO_(2)(001)surface without and with water and oxygen were studied by density functional theory(DFT).The adsorption energy of HCHO adsorption on S-doped TiO_(2) surface with water and oxygen(-709.62 kJ/mol)is much larger than that without water and oxygen(-312.14 kJ/mol).For HCHO adsorption system without water and oxygen,one CeH bond of HCHO molecule is broken.The oxygen and carbon atoms of HCHO are bonded to the titanium and sulfur atoms of SeTiO_(2) surface,respectively,and form a CH_(2)OS structure.For the system with water and oxygen,H_(2)O and HCHO molecules are both dissociated.HCHO molecule not only interacts with TiO_(2) surface,but also combines with O_(2) molecule.Two CeH bonds of HCHO are broken,one hydrogen atom(H1)is bonded to the sulfur atom(S)of TiO_(2) surface doping,while another hydrogen atom(H_(2))is bonded to the O atom(O_(2))of O_(2) molecule.The remaining CeO bond can be oxidized to form CO_(2) in subsequent action by oxygen from the atmosphere.The surface doping of sulfur have significant impact on the degradation of HCHO molecule on anatase TiO_(2)(001)surface with H_(2)O and O_(2). | Guofei Wu Cuihua Zhao Xi Zhou Jianhua Chen Yuqiong Li | 2019 | Journal of Materiomics2019，5，4： | 3 |
| 12 | Osteogenesis effects of magnetic nanoparticles modified-porous scaffolds for the reconstruction of bone defect after bone tumor resection显示文摘The treatment of bone defect after bone tumor resection is a great challenge for orthopedic surgeons.It should consider that not only to inhibit tumor growth and recurrence,but also to repair the defect and preserve the limb function.Hence,it is necessary to find an ideal functional biomaterial that can repair bone defects and inactivate tumor.Magnetic nanoparticles(MNPs)have its unique advantages to achieve targeted hyperthermia to avoid damage to surrounding normal tissues and promote osteoblastic activity and bone formation.Based on the previous stage,we successfully prepared hydroxyapatite(HAP)composite poly(lactic-co-glycolic acid)(PLGA)scaffolds and verified its good osteogenic properties,in this study,we produced an HAP composite PLGA scaffolds modified with MNPs.The composite scaffold showed appropriate porosity and mechanical characteristics,while MNPs possessed excellent magnetic and thermal properties.The cytological assay indicated that the MNPs have antitumor ability and the composite scaffold possessed good biocompatibility.In vivo bone defect repair experiment revealed that the composite scaffold had good osteogenic capacity.Hence,we could demonstrate that the composite scaffolds have a good effect in bone repair,which could provide a potential approach for repairing bone defect after bone tumor excision. | Ming Li Jianheng Liu Xiang Cui Guofei Sun Jianwei Hu Sijia Xu Fei Yang Licheng Zhang XiumeiWang Peifu Tang | 2019 | Regenerative Biomaterials2019，6，6： | 3 |
| 13 | Surveillance of pine wilt disease by high resolution satellite显示文摘Pine wilt disease caused by the pinewood nematode Bursaphelenchus xylophilus has led to the death of a large number of pine trees in China.This destructive disease has the characteristics of bring wide-spread,fast onset,and long incubation time.Most importantly,in China,the fatality rate in pines is as high as 100%.The key to reducing this mortality is how to quickly find the infected trees.We proposed a method of automatically identifying infected trees by a convolution neural network and bounding box tool.This method rapidly locates the infected area by classifying and recognizing remote sensing images obtained by high resolution earth observation Satellite.The recognition accuracy of the test data set was 99.4%,and the remote sensing image combined with convolution neural network algorithm can identify and determine the distribution of the infected trees.It can provide strong technical support for the prevention and control of pine wilt disease. | Hongwei Zhou Xinpei Yuan Huanyu Zhou Hengyu Shen Lin Ma Liping Sun Guofei Fang Hong Sun | 2022 | Journal of Forestry Research2022，33，4： | 2 |
| 14 | Validation of Landsat land surface temperature product in the conterminous United States using in situ measurements from SURFRAD, ARM, and NDBC sites显示文摘Since 1982,Landsat series of satellite sensors continuously acquired thermal infrared images of the Earth’s land surface.In this study,Landsat 5,7,and 8 land surface temperature(LST)products in the conterminous United States from 2009 to 2019 were validated using in situ measurements collected at 6 SURFRAD(Surface Radiation Budget Network)sites,6 ARM(Atmospheric Radiation Measurement)sites,and 9 NDBC(National Data Buoy Center)sites.The results indicate that a relatively consistent performance among Landsat 5,7,and 8 LST products is obtained for most sites due to the consistent LST retrieval algorithm in conjunction with the same atmospheric compensation and land surface emissivity(LSE)correction methods for Landsat 5,7,and 8 sensors.Large bias and root mean square error(RMSE)of Landsat LST product are obtained at some vegetated sites due to incorrect LSE estimation where LSE is invariant with the increasing of normalized difference vegetation index(NDVI).Except for the sites with incorrect LSE estimation,a mean bias(RMSE)of the differences between Landsat LST and in situ LST is 1.0 K(2.1 K)over snow-free land surfaces,−1.1 K(1.6 K)over snow surfaces,and−0.3 K(1.1 K)over water surfaces. | Si-Bo Duan Zhao-Liang Li Wei Zhao Penghai Wu Cheng Huang Xiao-Jing Han Maofang Gao Pei Leng Guofei Shang | 2021 | International Journal of Digital Earth2021，14，5： | 2 |
| 15 | Mining Sensor Data in Cyber-Physical Systems显示文摘A Cyber-Physical System(CPS) integrates physical devices(i.e., sensors) with cyber(i.e., informational)components to form a context sensitive system that responds intelligently to dynamic changes in real-world situations. Such a system has wide applications in the scenarios of traffic control, battlefield surveillance,environmental monitoring, and so on. A core element of CPS is the collection and assessment of information from noisy, dynamic, and uncertain physical environments integrated with many types of cyber-space resources. The potential of this integration is unbounded. To achieve this potential the raw data acquired from the physical world must be transformed into useable knowledge in real-time. Therefore, CPS brings a new dimension to knowledge discovery because of the emerging synergism of the physical and the cyber. The various properties of the physical world must be addressed in information management and knowledge discovery. This paper discusses the problems of mining sensor data in CPS: With a large number of wireless sensors deployed in a designated area, the task is real time detection of intruders that enter the area based on noisy sensor data. The framework of IntruMine is introduced to discover intruders from untrustworthy sensor data. IntruMine first analyzes the trustworthiness of sensor data, then detects the intruders' locations, and verifies the detections based on a graph model of the relationships between sensors and intruders. | Lu-An Tang Jiawei Han Guofei Jiang | 2014 | Tsinghua Science and Technology2014，19，3： | 2 |
| 16 | The processes and characteristics of mass balance on the Urumqi Glacier No. 1 during 1958-2009显示文摘As a solid reservoir, a glacier can regulate regional water resources. The annual net mass balance directly reflects the fluctuation of the glacier and climate variability. Based on 51 years of mass balance observation data, the mass balance of Tianshan Mountains Urumqi Glacier No. 1 experienced a nine times positive balance fluctuation and nine times negative balance fluctuation. There were 35 and 16 negative and positive balance years, respectively. From 1996/97 to 2008/09, 12 consecutive negative balance years were observed at Tianshan Mountains Urumqi Glacier No. 1. These results demonstrate that the Urumqi Glacier No. 1 is experiencing a strong negative balance, and the strongest negative balance, 931 mm w.e. (mm water equivalent), during the observation period occurred in 2008. In addition, the cumulative mass balance reached 13,709 mm w.e. in 2008. However, in 2009, the mass balance was positive at 63 mm w.e. The equilibrium-line altitude changes with the fluctuation in the mass balance, and the effective mass balance gradient is 7.4 mm/m. In this paper, the headwaters of the Urumqi River were analyzed using meteorological data from 1958 to 2009, including the average seasonal temperature and precipitation. The results showed that the main factor associated with the mass balance variation of Glacier No. 1 is the fluctuation in the summer air temperature, followed by changes in the precipitation. | WenBin Wang ZhongQin Li GuoFei Zhang XuLiang Li | 2012 | Research in Cold and Arid Regions2012，4，6： | 2 |
