| 3 | Crop 3D a LiDAR based platform for 3D high-throughput crop phenotyping显示文摘With the growing population and the reducing arable land, breeding has been considered as an effective way to solve the food crisis.As an important part in breeding, high-throughput phenotyping can accelerate the breeding process effectively. Light detection and ranging(LiDAR) is an active remote sensing technology that is capable of acquiring three-dimensional(3 D) data accurately,and has a great potential in crop phenotyping. Given that crop phenotyping based on LiDAR technology is not common in China,we developed a high-throughput crop phenotyping platform, named Crop 3 D, which integrated LiDAR sensor, high-resolution camera, thermal camera and hyperspectral imager. Compared with traditional crop phenotyping techniques, Crop 3 D can acquire multi-source phenotypic data in the whole crop growing period and extract plant height, plant width, leaf length, leaf width, leaf area, leaf inclination angle and other parameters for plant biology and genomics analysis. In this paper, we described the designs,functions and testing results of the Crop 3 D platform, and briefly discussed the potential applications and future development of the platform in phenotyping. We concluded that platforms integrating LiDAR and traditional remote sensing techniques might be the future trend of crop high-throughput phenotyping. | Qinghua Guo Fangfang Wu Shuxin Pang Xiaoqian Zhao Linhai Chen Jin Liu Baolin Xue Guangcai Xu Le Li Haichun Jing Chengcai Chu | 2018 | Science China(Life Sciences)2018,61,3: | 14 |
| 4 | Highly sensitive ethanol gas sensor based on ultrathin nanosheets assembled Bi_2WO_6 with composite phase显示文摘Bismuth tungstate(Bi2 WO6) has many intriguing properties and has been the focus of studies in a variety of fields, especially photocatalysis. However, its application in gas-sensing has been seldom reported.Here, we successfully synthesized assembled hierarchical Bi2 WO6 which consists of ultrathin nanosheets with crystalline-amorphous composite phase by a one-step hydrothermal method. X-ray diffraction(XRD), X-ray photoemission spectroscopy(XPS), field-emission scanning electron microscopy(FESEM),and high-resolution transmission electron microscopy(HRTEM) techniques were employed to characterize its composition, morphology, and microstructure. By taking advantage of its unique microstructure,phase composition, and large surface area, we show that the resulting Bi2 WO6 is capable of detecting ethanol gas with quick response(7 s) and recovery dynamic(14 s), extremely high sensitivity(Ra/Rg= 60.8@50 ppm ethanol) and selectivity. Additionally, it has excellent reproducibility and long-term stability(more than 50 d). The Bi2 WO6 outperform the existing Bi2 WO6-based and most of the other state-of-the-art sensing platforms. We not only provided one new member to the field of gas sensor,but also offered several strategies to reconstruct nanomaterials. | Tongwei Yuan Zhijun Li Wenshuang Zhang Zhenggang Xue Xiaoqian Wang Zhiheng Ma Yu Fan Jiaqiang Xu Yuen Wu | 2019 | Science Bulletin2019,64,9: | 5 |
| 5 | Contribution of Temperature Increase to Restrain the Transmission of COVID-19显示文摘The COVID-19 outbreak has already become a global pandemic and containing this rapid worldwide transmission is of great challenge.The impacts of temperature and humidity on the COVID-19 transmission rate are still under discussion.Here,we elucidated these relationships by utilizing two unique scenarios,repeated measurement and natural experiment,using the COVID-19 cases reported from January 23–February 21,2020,in China.The modeling results revealed that higher temperature was most strongly associated with decreased COVID-19 transmission at a lag time of 8 days.Relative humidity(RH)appeared to have only a slight effect.These findings were verified by assessing SARSCoV-2 infectivity under the relevant conditions of temperature(4C–37C)and RH(>40%).We concluded that temperature increase made an important,but not determined,contribution to restrain the COVID19 outbreak in China.It suggests that the emphasis of other effective controlling polices should be strictly implemented to restrain COVID19 transmission in cold seasons. | Mengyuan Ren Rongjuan Pei Bahabaike Jiangtulu Junxi Chen Tao Xue Guofeng Shen Xiaoru Yuan Kexin Li Changxin Lan Zhen Chen Xinwen Chen Yun Wang Xiaoqian Jia Zewu Li Audil Rashid Tippawan Prapamontol Xiuge Zhao Zhaomin Dong Yali Zhang Le Zhang Rongwei Ye Zhiwen Li Wuxiang Guan Bin Wang | 2021 | The Innovation2021,2,1: | 2 |
| 6 | Modeling the Prevalence of Asymptomatic COVID-19 Infections in the Chinese Mainland显示文摘Recently,considerable efforts have been focused on intensifying the screening process for asymptomatic COVID-19 cases in the ChineseMainland,especially for up to 10 million citizens living in Wuhan City by nucleic acid testing.However,a high percentage of domestic asymptomatic cases did not develop into symptomatic ones,which is abnormal and has drawn considerable public attention.Here,we aimed to investigate the prevalence of COVID-19 infections in the Chinese Mainland from a statistical perspective,as it is of referential significance for other regions.By conservatively assuming a development time lag from pre-symptomatic(i.e.,referring to the infected cases that were screened before the COVID-19 symptom onset)to symptomatic as an incubation time of 5.2 days,our results indicated that 92.5%of those tested in Wuhan City,China,and 95.1%of those tested in the Chinese Mainland should have COVID-19 syndrome onset,which was extremely higher than their corresponding practical percentages of 0.8%and 3.3%,respectively.We propose that a certain false positive rate may exist if large-scale nucleic acid screening tests for asymptomatic cases are conducted in common communities with a low incidence rate.Despite adopting relatively high-sensitivity,high-specificity detection kits,we estimated a very low prevalence of COVID-19 infections,ranging from 106 to 104 in both Wuhan City and the Chinese Mainland.Thus,the prevalence rate of asymptomatic infections in China had been at a very low level.Furthermore,given the lower prevalence of the infection,close examination of the data for false positive results is necessary to minimize social and economic impacts. | Xiaoqian Jia Junxi Chen Liangjing Li Na Jia Bahabaike Jiangtulu Tao Xue Le Zhang Zhiwen Li Rongwei Ye Bin Wang | 2020 | The Innovation2020,1,2: | 1 |

| 10 | Endoplasmic reticulum stress is involved in retinal injury induced by repeated transient spikes of intraocular pressure显示文摘Clinically,a large proportion of glaucoma patients undergo repeated intraocular pressure(IOP)spike(Spike IOP)attacks during their sleep,which may facilitate retinopathy.In this study,we established a mouse model of repeated transient Spike IOP to investigate the direct damage to the retina following Spike IOP attacks,and elucidated the underlying molecular mechanism.We analyzed the changes in the number of retinal ganglion cells(RGCs)via immunofluorescence.Thereafter,we detected retinal cell apoptosis via terminal deoxynucleotidyl transferase deoxyuridine triphosphate(d UTP)nick-end labeling(TUNEL)staining,and performed RNA sequencing(RNA-seq)to reveal the underlying molecular mechanism.Finally,we validated the expression of key molecules in the endoplasmic reticulum(ER)stress pathway using quantitative real-time polymerase chain reaction(q RT-PCR)and western blot analysis.Results revealed a time-dependent RGC loss in Spike IOP,evidenced by a reduction in the number of Brn3 a-positive RGCs in experimental eyes following a 7-d continuous treatment with Spike IOP.In addition,TUNEL staining indicated that apoptosis of retinal cells started in the outer nuclear layer(ONL),and then spread to the ganglion cell layer(GCL)with time.RNA-seq analysis revealed that ER stress might be involved in Spike IOP-induced retinal injury.This result was corroborated by western blot,which revealed upregulation of ER stress-related proteins including binding immunoglobulin protein/glucose-regulated protein 78(Bi P/GRP78),phosphorylated inositolrequiring enzyme 1(p-IRE1),unspliced X-box-binding protein 1(XBP1-u),spliced X-box-binding protein 1(XBP1-s),phosphorylated c-Jun N-terminal kinase(p-JNK),C/EBP-homologous protein(CHOP),and B-cell lymphoma 2(Bcl-2)-associated X protein(Bax).These findings indicate that repeated IOP transients are detrimental to the retina,while ER stress plays an important role in retinal cell apoptosis in this situation.Notably,repeated Spike IOP among glaucoma patients is a crucial factor for progressive retinopathy. | Xue YANG Xiaowei YU Zhenni ZHAO Yuqing HE Jiamin ZHANG Xiaoqian SU Nannan SUN Zhigang FAN | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021,22,9: | 0 |
| 11 | Storage, form, and influencing factors of karst inorganic carbon in a carbonate area in China显示文摘Carbonate rock chemical weathering carbon sinks reduce the rate of increase of the atmospheric CO_(2) concentration and global warming. However, uncertainty still exists in the estimation results of carbonate rock chemical weathering carbon sink fluxes(CCSF), and the contributions of climate change and ecological restoration to the CCSF are not clear. To this end, we compiled published site data on ion concentrations in different watersheds in China and used a classical thermodynamic dissolution model to reassess the potential and spatial and temporal patterns of the CCSF in China from 1991 to 2020. We quantified the contributions of temperature(MAT), precipitation(MAP), evapotranspiration(ET), soil water(SM), and the normalized difference vegetation index(NDVI) to the CCSF. The results revealed that(1) China's CCSF was 22.76 t CO_(2)km^(-2)yr^(-1), which was higher than the global average(15.77 t CO_(2)km^(-2)yr^(-1)). The total carbonate rock chemical weathering carbon sink(CCS) was 4772.67×10^(4)t CO_(2), contributing 14.91% of the global CCS through a carbonate rock area of 252.98×10^(4)km^(-2).(2) China's CCSF decreased gradually from southeast to northwest, with values of 33.14, 12.93, and7.27 t CO_(2)km^(-2)yr^(-1)in the southern karst, Qinghai-Tibetan karst, and northern karst regions, respectively.(3) The overall CCSF in China exhibited an increasing trend from 1991 to 2020, with a rate of increase of 0.16 t CO_(2)km^(-2)yr^(-1).(4) The contributions of the MAP, MAT, ET, SM, and NDVI to the CCSF were 63.3%, 3.02%, 27.5%, 3.1%, and 3.05%, respectively. Among them, the increase in precipitation was the main contributor to the increase in the CCSF in China over the last 30 years, while the enhancement of ET offset part of the positive contribution of the increase in precipitation to the CCSF. In conclusion, the results of this study provide a systematic quantification of the magnitude, the patterns, and the influencing factors of CCS over a long time series in China. The results are of great significance and provide a reference for the diagnosis and gap analysis of the national and global carbon neutrality capacities. | Chaochao DU Xiaoyong BAI Yangbing LI Qiu TAN Cuiwei ZHAO Guangjie LUO Luhua WU Fei CHEN Chaojun LI Chen RAN Sirui ZHANG Lian XIONG Fengjiao SONG Biqin XIAO Zilin LI Yingying XUE Mingkang LONG Qing LUO Xiaoyun ZHANG Minghui LI Xiaoqian SHEN Shu YANG | 2024 | Science China Earth Sciences2024,67,3: | 0 |
| 12 | Modified room temperature solid-state synthesis of yttria-stabilized zirconia(YSZ) nano-powders for solid oxide fuel cells显示文摘High-performance solid oxide fuel cell(SOFC) is in urgent need of high-quality electrolyte powders with high reactivity and chemical uniformity.Here,8 mol% Y_(2)O_(3) doped ZrO_(2)(YSZ) nano-powders were synthesized by an improved solid-state reaction method at ambient temperature,and were applied to the fabrication of SOFC electrolytes.YSZ nano-powders show average grain sizes of ^(2)0 nm and high dispersibility,which is comparable with or even better than some other chemical methods.Benefitting from their high reactivity,dense YSZ electrolytes(relative density of 97.9%) can be obtained at a relatively low sintering temperature of 1400℃.The optimized electrical conductivity reaches up to a high value of0.034 S/cm at 800 0C in air.The anode supported single cell with the construction of Ni-YSZ/YSZ/Sm_(0.2)Ce_(0.8)O_(2-δ)(SDC)/La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)(LSCF) exhibits the peak power density of 0.827 W/cm^(2) at800℃ while taking wet H_(2) as fuels and ambient air as oxidants. | Xiaoqian Xu Yurun Feng Zhaoyu Zhong Xue Guo Zhenhao Zhang Jiao Li Shikai Zhao Shigang Wu Haibin Sun | 2023 | Journal of Rare Earths2023,41,9: | 0 |
| 13 | The neuroprotection of electro-acupuncture via the PGC-1α/TFAM pathway in transient focal cerebral ischemia rats显示文摘ATP depletion is one of the pathological bases in cerebral ischemia.Electro-acupuncture(EA)is widely used in clinical practice for ischemia.However,the mechanism of EA remains unclear.The purpose of this study was to investigate whether EA could activate the AMPK/PGC-1α/TFAM signaling pathway and,consequently,increase the preservation of ATP in rats with ischemia.In this study,48 rats were randomly divided into four groups as a sham-operation control group(sham group),a middle cerebral artery occlusion group(MCAO group),an EA group,and an EA group blocked by the AMPK inhibitor compound C(EA+CC group)(N=12/group).The rats of the EA group and EA+CC group received the EA treatment for 7 days.The rats that belonged in the two remaining groups were only grasped in the same condition.Then,their brain tissues were collected for further detection.When compared with other groups,EA significantly reduced neurological deficits score and increased motor function.The cerebral infarction volume was significantly reduced in the EA group according to TTC staining.With western blot,we found that EA improved the ratio of p-AMPKα/AMPKα(P<0.05),however,there is no difference between the MCAO group and sham group(P>0.05).In addition,EA also increased the expression of PGC-1αand TFAM(all P<0.05).By Elisa,we observed that EA increased the preservation of ATP(P<0.05)and mitochondrial respiratory enzymes,including Complex I(P<0.05),Complex IV(P<0.05),but not Complex III(P>0.05).In summary,we conclude that EA may protect against ischemic damage in MCAO rats,improve the preservation of ATP and mitochondrial respiratory enzymes.This effect may be positively regulated by the activation of the PGC-1α/TFAM signaling pathway. | LUPING YANG YIJING JIANG XIAOQIAN YE YONGMEI YOU LING LIN JING LIAN JUAN LI SHANLI YANG XIEHUA XUE | 2022 | BIOCELL2022,46,1: | 0 |
