| 1 | RESEARCH OF WAVELET TRANSFORM INSTRUMENT SYSTEM FOR SIGNAL ANALYSIS显示文摘After brief describing the Principle of wavelet transform (WT) of signals, a new signals analysis system based on wavelet transform is introduced. The design and development of the instryment of wavelet transform are described. A number of practical uses of this system demonstrate that wavelet transform system is specially functional in identifying and processing impulse, singular and non-smooth signals, so that it should be evaluated the most advanced signal analyzing system. | Qin Shuren Chen Zhikui Tang Baoping Yang Changqi Xu Mingtao He Hui (Test Center, Chongqing University) | 2000 | Chinese Journal of Mechanical Engineering2000，13，2： | 11 |
| 2 | Research on proton radiation effects on CMOS image sensors with experimental and particle transport simulation methods显示文摘Recently,complementary metal-oxide semiconductor image sensors(CISs)have become a key element of the imaging instrument and have been widely used in many scientific applications[1,2]such as space remote sensing,medical imaging,and nuclear power plant monitoring.However,CISs used in these harsh radiation environments are susceptible to damage by particles or rays. | Yuanyuan XUE Zujun WANG Minbo LIU Baoping HE Zhibin YAO Jiangkun SHENG Wuying MA Guantao DONG Junshan JIN | 2017 | Science China(Information Sciences)2017，60，12： | 6 |
| 3 | Comparison of the dark signal degradation induced by Gamma ray, proton, and neutron radiation in pinned photodiode CMOS image sensors显示文摘Dear editor,CMOS image sensors (CISs) present numerous advantages and have become feasible alternatives for CCDs (charge coupled devices) in satellite imaging system, nuclear industry, and particle detection (1–3)However, CISs used in these applications are often operated under harsh radiation environments and are susceptible to total ionizing dose (TID) and displacement damage. | Zujun WANG Yuanyuan XUE Wei CHEN Rui XU Hao NING Baoping HE Zhibin YAO Minbo LIU Jiangkun SHENG Wuying MA Guantao DONG | 2019 | Science China(Information Sciences)2019，62，6： | 4 |
| 4 | Habitat restoration is the greatest challenge for population recovery of Hainan gibbons(Nomascus hainanus)显示文摘Hainan gibbons are among the world’s most critically endangered primates,with a remaining population of only 35 individuals distributed across 5 social groups in the Bawangling Branch of the Hainan Tropical Rainforest National Park,China.Habitat conversion and forest fragmentation over the past 40 years have reduced their geographical distribution by 95%.In the absence of a quantitative assessment of the availability of remaining suitable habitat,it is unclear whether this species can survive to the end of this century.We used behavioral observations,ArcGIS,remote sensing,stereo optical imagery,and MaxEnt modeling to identify patterns of Hainan gibbon range use and compare changes in the distribution of suitable forest types and areas of forest fragmentation over the past 20 years(2000–2020).The results indicate that the combined range of the 5 extant Hainan gibbon groups totaled 14.89 km2.The home range of the smallest group(Group E,3 individuals)was 1.51 km2,which likely represents the minimum home range size for this species.The remaining area of highly suitable and moderately suitable habitat totals 26.9 km2.However,habitat connectivity across the gibbon range is very low(less than 0.5),limiting the ability of Hainan gibbons to move between forest patches.The results of this study indicate that the availability of suitable habitat in Bawangling is insufficient to allow for future Hainan gibbon population growth.Therefore,immediate action must be taken to restore,reforest,and establish ecological corridors to reconnect areas of suitable habitat for these critically endangered gibbons. | Qingqing HE Shasha YAN Paul A.GARBER Baoping REN Xvming QI Jiang ZHOU | 2023 | Integrative Zoology2023，18，4： | 2 |
| 5 | Modeling dark signal of CMOS image sensors irradiated by reactor neutron using Monte Carlo method显示文摘The dark signal degradation of the CMOS image sensor(CIS) was induced by neutron radiation,and it was modeled by Geant4, which is a three-dimensional Monte Carlo code. The simplified model of the CIS array was established according to the actual pixel geometry, material, and doping concentration. Nuclear elastic interaction and capture interaction were included in the physical processes, and the displacement damage dose in the space charge region of the pixel was calculated. The mean dark signal and dark signal distribution were modeled using Geant4, and the physical mechanisms were analyzed. The modeling results were in good agreement with the experimental and theoretical results. | Yuanyuan XUE Zuun WANG Wei CHEN Baoping HE Zhibin YAO Minbo LIU Jiangkun SHENG Wuying MA Guantao DONG Junshan JIN | 2018 | Science China(Information Sciences)2018，61，6： | 2 |

| 10 | Spatially discontinuous ionization phenomenon in inhomogeneous soil显示文摘By using X-ray film imaging technology,a phenomenon of discontinuous ionization was observed in the inhomogeneous soil around the grounding electrode on which a surge voltage was applied.A simplified two-phase solid-gas model was built to study the electric field distribution in the soil to explain the discontinuous ionization phenomenon.Analysis showed the differences of the dielectric properties,the shapes and sizes of soil particles can cause discontinuous ionization in the soil. | ZHANG BaoPing,HE JinLiang & ZENG Rong State Key Lab of Power Systems,Department of Electrical Engineering,Tsinghua University,Beijing 100084,China | 2010 | Science China(Technological Sciences)2010，53，4： | 1 |
| 11 | Characterization of the core microflora and nutrient composition in packaged pasteurized milk products during storage显示文摘Pasteurized milk contains complex microbial communities affected by sterilization and storage conditions.This complex microflora may be the possible reason that pasteurized dairy products are highly prone to spoilage.In this study,packaged pasteurized milk products collected from dairy processing factories in China were stored at 0,4,10,15,and 25℃ for 0−15 days and subjected to microbial identification using high-throughput sequencing.Accordingly,6 phyla and 44 genera were identified as the dominant microbiota.Moreover,the changes in nutritional composition of the pasteurized milk,including in 16 free amino acids,7 taste values,and 8 chemical constituents,were analyzed using principal component and multi-factor analyses.The Pearson correlation analysis identified Pseudomonas,Aeromonas,Paenibacillus,and Serratia genera as the core functional microbiota that significantly affects the nutritional composition of pasteurized milk.Hence,the results provide a comprehensive understanding of the safety and shelf-life of stored pasteurized milk. | Ruixue Ding Shanshan Yang Lijuan Geng Yumeng Liu Baoping He Liyun Liu Xiqing Yue Rina Wu Junrui Wu | 2023 | Food Science and Human Wellness2023，12，4： | 0 |
| 12 | Study of strip-shaped chromatic aberration defects on the surface of an electro-galvanized fingerprint-resistant sheet显示文摘Strip-shaped chromatic aberration defects on the surface of an electro-galvanized fingerprint-resistant sheet were systematically studied using Thermo-Calc thermodynamic calculations,scanning electron microscope and X-ray diffractometer analyses,and rapid heat treatment simulation technology.The formation mechanism of these defects was also analyzed.The results show a strong correlation between the defects and the uneven distribution of the Fe(001)component on the surface of the steel substrate.The relatively high proportion of Fe(001)components on the surface of the steel substrate affects the distribution density of the Zn crystal cells in different orientations during the electrodeposition process,which causes the reflection intensity of the light of the galvanized layer to differ from various visual perspectives,and macroscopic strip-shaped chromatic aberration defects are finally formed.The high proportion of the Fe(001)component on the surface of the steel substrate is mainly related to the following two factors.First,when the strip steel is hot-rolled,the finishing hot-rolling temperature is close to theγ→αphase transition temperature.When the local temperature on the upper surface of the strip steel is low,γ+αtwo-phase rolling easily occurs,and this results in an uneven stress distribution between theγandαphases after the hot-rolling process.This uneven distribution of hot-rolling stress results in the formation of a coarse grain structure in the local area on the surface of the hot-rolled sheet,which strongly affects the subsequent cold rolling and annealing process,and the annealed steel sheet substrate ultimately contains a greater proportion of the Fe(001)component.And second,a fast cooling rate(>10 K/s)during the slow cooling stage in the continuous annealing process inhibits the transformation of the Fe(001)to the Fe(111)component on the surface of the cold-rolled steel sheet,and it is then not possible to effectively eliminate the influence of the unevenly distributed Fe(001)component on the surface of the annealed steel sheet(originating from the uneven hot-rolled microstructure).This uneven distribution of the Fe(001)component on the surface of the annealed steel sheet following the continuous annealing heat treatment has a strong effect on the electrodeposition behavior of the Zn crystal cell in the subsequent electroplating process and the formation of macroscopic strip-shaped chromatic aberration defects on the surface of electro-galvanized fingerprint-resistant sheet. | HE Yutian HUANG Shengbiao ZHANG Baoping | 2023 | Baosteel Technical Research2023，17，2： | 0 |
