| 1 | An EcoCity model for regulating urban land cover structure and thermal environment: Taking Beijing as an example显示文摘Urban land-use/cover changes and their effects on the eco-environment have long been an active research topic in the urbanization field. However, the characteristics of urban inner spatial heterogeneity and its quantitative relationship with thermal environment are still poorly understood, resulting in ineffective application in urban ecological planning and management.Through the integration of 'spatial structure theory' in urban geography and 'surface energy balance' in urban climatology, we proposed a new concept of urban surface structure and thermal environment regulation to reveal the mechanism between urban spatial structure and surface thermal environment. We developed the EcoCity model for regulating urban land cover structure and thermal environment, and established the eco-regulation thresholds of urban surface thermal environments. Based on the comprehensive analysis of experimental observation, remotely sensed and meteorological data, we examined the spatial patterns of urban habitation, industrial, infrastructure service, and ecological spaces. We examined the impacts of internal land-cover components(e.g., urban impervious surfaces, greenness, and water) on surface radiation and heat flux. This research indicated that difference of thermal environments among urban functional areas is closely related to the proportions of the land-cover components.The highly dense impervious surface areas in commercial and residential zones significantly increased land surface temperature through increasing sensible heat flux, while greenness and water decrease land surface temperature through increasing latent heat flux. We also found that different functional zones due to various proportions of green spaces have various heat dissipation roles and ecological thresholds. Urban greening projects in highly dense impervious surfaces areas such as commercial, transportation, and residential zones are especially effective in promoting latent heat dissipation efficiency of vegetation, leading to strongly cooling effect of unit vegetation coverage. This research indicates that the EcoCity model provides the fundamentals to understand the coupled mechanism between urban land use structure and surface flux and the analysis of their spatiotemporal characteristics. This model provides a general computational model system for defining urban heat island mitigation, the greening ratio indexes, and their regulating thresholds for different functional zones. | KUANG WenHui YANG TianRong LIU AiLin ZHANG Chi LU DengSheng CHI WenFeng | 2017 | Science China Earth Sciences2017，60，6： | 16 |
| 2 | Remote sensing-based artificial surface cover classification in Asia and spatial pattern analysis显示文摘Artificial surfaces, characterized with intensive land-use changes and complex landscape structures, are important indicators of human impacts on terrestrial ecosystems. Without high-resolution land-cover data at continental scale, it is hard to evaluate the impacts of urbanization on regional climate, ecosystem processes and global environment. This study constructed a hierarchical classification system for artificial surfaces, promoted a remote sensing method to retrieve subpixel components of artificial surfaces from 30-m resolution satellite imageries(Globe Land30) and developed a series of data products of high-precision urban built-up areas including impervious surface and vegetation cover in Asia in 2010. Our assessment, based on multisource data and expert knowledge, showed that the overall accuracy of classification was 90.79%. The mean relative error for the impervious surface components of cities was 0.87. The local error of the extracted information was closely related to the heterogeneity of urban buildings and vegetation in different climate zones. According to our results, the urban built-up area was 18.18×104 km2, accounting for 0.59% of the total land surface areas in Asia; urban impervious surfaces were 11.65×104 km2, accounting for 64.09% of the total urban built-up area in Asia. Vegetation and bare soils accounted for 34.56% of the urban built-up areas. There were three gradients: a concentrated distribution, a scattered distribution and an indeterminate distribution from east to west in terms of spatial pattern of urban impervious surfaces. China, India and Japan ranked as the top three countries with the largest impervious surface areas, which respectively accounted for 32.77%, 16.10% and 11.93% of the urban impervious surface area of Asia. We found the proportions of impervious surface and vegetation cover within urban built-up areas were closely related to the economic development degree of the country and regional climate environment. Built-up areas in developed countries had relatively low impervious surface and high public green vegetation cover, with 50–60% urban impervious surfaces in Japan, South Korea and Singapore. In comparison, the proportion of urban impervious surfaces in developing countries is approaching or exceeding 80% in Asia. In general, the composition and spatial patterns of built-up areas reflected population aggregation and economic development level as well as their impacts on the health of the environment in the sub-watershed. | KUANG WenHui CHEN LiJun LIU JiYuan XIANG WeiNing CHI WenFeng LU DengSheng YANG TianRong PAN Tao LIU AiLin | 2016 | Science China Earth Sciences2016，59，9： | 12 |
| 3 | Bilayer dissolving microneedle array containing 5-fluorouracil and triamcinolone with biphasic release profile for hypertrophic scar therapy显示文摘Hypertrophic scar(HS)is an undesirable skin abnormality following deep burns or operations.Although intralesional multi-injection with the suspension of triamcinolone acetonide(TA)and 5-fluorouracil(5-Fu)has exhibited great promise to HS treatment in clinical,the difference of metabolic behavior between TA and 5-Fu remarkably compromised the treatment efficacy.Besides,the traditional injection with great pain is highly dependent on the skill of the experts,which results in poor compliance.Herein,a bilayer dissolving microneedle(BMN)containing TA and 5-Fu(TA-5-Fu-BMN)with biphasic release profile was designed for HS therapy.Equipped with several micro-scale needle tips,the BMN could be self-pressed into the HS with uniform drug distribution and less pain.Both in vitro permeation and in vivo HS retention tests revealed that TA and 5-Fu could coexist in the scar tissue for a sufficient time period due to the well-designed biphasic release property.Subsequently,the rabbit ear HS model was established to assess therapeutic efficacy.The histological analysis showed that TA-5-Fu-BMN could significantly reduce abnormal fibroblast proliferation and collagen fiber deposition.It was also found that the value of scar elevation index was ameliorated to a basal level,together with the downregulation of mRNA and protein expression of Collagen I(Col I)and transforming growth factor-β1(TGF-β1)after application of TA-5-Fu-BMN.In conclusion,the BMN with biphasic release profiles could serve as a potential strategy for HS treatment providing both convenient administrations as well as controlled drug release behavior. | Beibei Yang Yating Dong Yifeng Shen Ailin Hou Guilan Quan Xin Pan Chuanbin Wu | 2021 | Bioactive Materials2021，6，8： | 8 |
| 4 | Analysis and construction status of SG-Ⅱ 5PW laser facility显示文摘We present a recent progress of the SG-II 5 PW facility, which designed a multi-petawatt ultrashort pulse laser based on optical parametric chirped-pulse amplification(OPCPA). The prior two optical parametric amplifiers have been accomplished and chirped pulses with an energy of 49.7 J and a full-width-at-half-maximum(FWHM) spectrum bandwidth of 85 nm have been achieved. In the PW-scale optical parametric amplification(OPA), with the pump pulse that has an energy of 118 J from the second harmonic generation of the SG-II 7 th beam, the pump-to-signal conversion efficiency is up to 41.9%, which to the best of our knowledge is the highest among all of the reported values for OPCPA systems. The compressed pulse is higher than 37 J in 21 fs(1.76 PW), and the focal spot is ~10 μm after the closed-loop corrections by the adaptive optics. Limited by the repetition of the pump laser, the SG-II 5 PW facility operates one shot per hour. It has successfully been employed for high energy physics experiments. | Jianqiang Zhu Xinglong Xie Meizhi Sun Jun Kang Qingwei Yang Ailin Guo Haidong Zhu Ping Zhu Qi Gao Xiao Liang Ziruo Cui Shunhua Yang Cheng Zhang Zunqi Lin | 2018 | High Power Laser Science and Engineering2018，6，2： | 7 |

| 7 | Theory, technology and prospects of conventional and unconventional natural gas显示文摘The development of natural gas in China has entered a golden and leap-forward stage, which is a necessary bridge to clean energy. This in-depth study on the status quo, theory, technology and prospect of natural gas development shows:(1) The global remaining proven recoverable reserves of natural gas are 186×1012 m3, and the reserves-production ratio is 52.4, indicating a solid resource base for long-term and rapid development.(2) Ten formation and distribution laws of conventional and unconventional natural gas reservoirs have been proposed. In terms of exploration geology, the theory of conventional 'monolithic' giant gas fields with different gas sources, and an unconventional gas accumulation theory with continuous distribution of 'sweet areas' in different lithologic reservoirs have been established; in terms of development geology, a development theory of conventional structural gas reservoirs is oriented to 'controlling water intrusion', while a development theory of unconventional gas is concentrated on man-made gas reservoirs.(3) With the geological resources(excluding hydrates) of 210×1012 m3 and the total proven rate of the resources less than 2% at present, the natural gas in China will see a constant increase in reserve and production; by 2030, the proven geological reserves of natural gas are expected to reach about(6 000-7 000)×108 m3, the production of conventional and unconventional natural gas each will reach about 1 000×108 m3, and the gas consumption will reach 5 500×108 m3. The dependence on imported natural gas may be 64% by 2030, and 70% by 2050.(4) Ten measures for future development of natural gas have been proposed, including strengthening exploration in large-scale resource areas, increasing the development benefits of unconventional gas, and enhancing the peak adjusting capacity of gas storage and scale construction of liquified natural gas. | ZOU Caineng YANG Zhi HE Dongbo WEI Yunsheng LI Jian JIA Ailin CHEN Jianjun ZHAO Qun LI Yilong LI Jun YANG Shen | 2018 | Petroleum Exploration and Development2018，45，4： | 4 |
| 8 | Determination of Cd-MT in Pteria penguin with Indirect Non-Competitive ELISA显示文摘Cadmium-metallothionein (Cd-MT) of Pteria penguin was used to immunize domestic rabbit in order to obtain polyclonal antibody against Cd-MT. Using the anti-Cd-MT antibody, a method of indirect non-competitive enzyme-linked immunosorbent assay (non-competitive ELISA) was established to detect shellfish Cd-MT. In this case, the minimum detectable concentration of P. penguin Cd-MT was (4.563±0.051) ng/mL. The linear range of detection was 9.75-2.0×104 ng/mL. Intra-assay relative standard deviation (RSD) was less than 11.6%, and inter-assay RSD less than 6.7%. The recovery rates ranged from 83.7% to 119.0%. The polyclonal antibody against Cd-MT of P. penguin can also be used to detect MT of other four types of shellfish. In the crude extracts from different organs of P. penguin, the MT concentrations determined by this method matched well with the concentrations of cadmium detected by the atomic absorption spectroscopy. | WU Xiaoping LIAO Ailin ZHANG Chaohua LIAO Yan LU Hongyu YANG Jie | 2011 | Wuhan University Journal of Natural Sciences2011，16，4： | 2 |
| 9 | Characterization of novel microsatellite markers of the Emei Shan Liocichla using restriction site-associated DNA sequencing显示文摘Background:The Emei Shan Liocichla(Liocichla omeiensis) is an endemic bird species to southwestern China with a small geographic range. However, little was known about the genetic status of this threatened species.Methods:We applied restriction-site-associated DNA sequencing(RAD-Seq) for rapid mass identification of microsatellite markers of the Emei Shan Liocichla.Results:A total of 11,564 microsatellite sequences were obtained, 600 random loci were designed for screening and 24 polymorphic microsatellite loci were selected for further validation. The average allele number, average observed heterozygosity and average expected heterozygosity were relatively low in our samples, which were 6.08, 0.6618 and 0.7048, respectively, indicating that the Emei Shan Liocichla might have lost some genetic diversity. Further analyses suggested that the populations distributed on two mountains(Daxiangling and Xiaoliangshan) showed a modest degree of genetic differentiation.Conclusions:These novel microsatellite markers provided valuable preliminary knowledge regarding the genetic status of the Emei Shan Liocichla and can be useful in further studies, as well as in the management and conservation of this species. | Ailin Yang De Chen Pengcheng Wang Yiqiang Fu Zhengwang Zhang | 2017 | Avian Research2017，8，2： | 2 |

| 11 | A bioinformatic evaluation of potential allergenicity of 85 candidate genes in transgenic organisms显示文摘The potential of genetically modified organisms(GMOs) to increase allergenicity or predispositions to allergies has attracted much attention.An approach that will properly and holistically evaluate the allergenicity of GMOs is yet to be found.Here,85 transgenes that have been reported in both international and domestic studies during recent years are summarized case by case;49 of the transformed genes were from plant sources and 36 were from animal sources.EVALLERTM,a web server for the in silico assessment of potential protein allergenicity,was used to evaluate the potential of the transgenic proteins as allergens.The biomedical journals listed in Highwire(http://gffzzd58bc32f34884012huwcnuko09q596nvc.ffgz.tsg.suse.edu.cn/) were searched and reviewed to decipher whether any of the transformed genes were linked to allergenicity or human health.The EVALLER analysis identified 5 allergenic genes,whilst our literature review found 11 genes that were either related to allergic cases or to clinical adverse events;all 16 of these genes have been used in GMOs.The analysis pathway that we have developed can help guide the selection of genes to be used in genetic modification.The pathway also provides a paradigm for allergenicity analysis of transgene candidates. | ZOU ZeHong HE Ying RUAN Lin SUN BaoQing CHEN HuiFang CHEN De LIU ShiMing YANG XiaoGuang TAO AiLin | 2012 | Chinese Science Bulletin2012，57，15： | 1 |
| 12 | Systematic study of spatiotemporal influences on temporal contrast in the focal region in large-aperture broadband ultrashort petawatt lasers显示文摘Temporal contrast is one of the crucial physical determinants which guarantee the successful performance of laser–matter interaction experiments. We generally reviewed the influences on the temporal contrast in three categories of noises based on the requirement by the physical mechanisms. The spatiotemporal influences on temporal contrast at the focal region of the chromatic aberration and propagation time difference introduced by large-aperture broadband spatial filters, which were spatiotemporally coupled with compression and focusing, were calculated and discussed with a practical case in SG-Ⅱ5 PW ultrashort petawatt laser. The system-wide spatiotemporal coupling existing in large-aperture broadband ultrashort petawatt lasers was proved to be one of the possible causes of temporal contrast degradation in the focal region. | Ping Zhu Xinglong Xie Jun Kang Qingwei Yang Haidong Zhu Ailin Guo Meizhi Sun Qi Gao Ziruo Cui Xiao Liang Shunhua Yang Dongjun Zhang Jianqiang Zhu | 2018 | High Power Laser Science and Engineering2018，6，1： | 1 |
| 13 | Characteristics and development model of karst reservoirs in the fourth member of Sinian Dengying Formation in central Sichuan Basin,SW China显示文摘The reservoir space,types and distribution characteristics of karst carbonate gas reservoirs in the fourth member of Sinian Dengying Formation(Deng 4 Member)in central Sichuan Basin are analyzed based on the drilling,logging and seismic data.A development model of karst reservoirs is constructed to support the high-efficiency development of gas pools.The research shows that the reservoirs in Deng 4 Member have mainly small-scale karst vugs and fractures as storage space,and can be divided into three types,fracture-vug,pore-vug and pore types.The development patterns of the karst reservoirs are determined.On the plane,the karst layers increase from 65 m to 170 m in thickness from the karst platform to the karst slope,and the high-quality reservoirs increase from 25.0 m to 42.2 m in thickness;vertically,the reservoirs at the top of Deng 4 Member appear in multiple layers,and show along-bedding and along fracture dissolution characteristics.The reservoirs at the bottom are characterized by the dissolution parallel to the water level during the karstification period,and have 3-5 large-scale fracture-cave systems.Based on the reservoir development characteristics and the genetic mechanism,three types of reservoir development models of karst reservoir are established,i.e.,bed-dissolved body,fracture-dissolved body and paleohorizon-dissolved body.The construction of karst reservoir development models and seismic response characteristics of the three types of reservoirs can provide parameter for well placement and trajectory design,and substantially improve productivity and development indices of individual wells and gas reservoirs.The designed production capacity of the gas reservoir has enhanced from the initial 3.6 billion to 6 billion cubic meters,making the profit of the reservoir development increase noticeably. | YAN Haijun HE Dongbo JIA Ailin LI Zhiping GUO Jianlin PENG Xian MENG Fankun LI Xinyu ZHU Zhanmei DENG Hui XIA Qinyu ZHENG Guoqiang YANG Shan SHI Xiaomin | 2022 | Petroleum Exploration and Development2022，49，4： | 1 |

| 15 | Research progress of p-type Fe-based skutterudite thermoelectric materials显示文摘Filled skutterudite is currently one of the most promising intermediate-temperature thermoelectric(TE)materials,having good thermoelectric transport performance and excellent mechanical properties.For the preparation of high-efficiency filled skutterudite TE devices,it is important to have p-and n-type filled skutterudite TE materials with matching performance.However,the current TE properties of p-type Fe-based filled skutterudite materials are worse than n-type filled skutterudite materials.Therefore,how to obtain high-performance p-type Fe-based filled skutterudite materials is the key to preparation of high-efficiency skutterudite-based TE devices.This review summarizes some methods for optimizing the thermal transport performance of p-type filled skutterudite materials at the atomic-molecular and nano-mesoscopic scale that have been used in recent years.These methods include doping,multi-atom filling,and use of low-dimensional structure and of nanocomposite.In addition,the synergistic optimization methods of the electrical and thermal transport parameters and advanced preparation technologies of p-type filled skutterudite materials in recent years are also briefly summarized.These optimizational methods and advanced preparation technologies can significantly improve the TE properties of p-type Fe-based filled skutterudite materials. | Xin TONG Zhiyuan LIU Jianglong ZHU Ting YANG Yonggui WANG Ailin XIA | 2021 | Frontiers of Materials Science2021，15，3： | 1 |
| 16 | A Simple BCH Decoder for NoC Interconnects and SoC Buses显示文摘Network on a chip(NoC)uses packetswitched network to implement interconnections in System on chip(SoC).In SoC design,performance and energy efficiency are respectively the first and second priorities,and optimal on-chip communication should decrease the power consumption and area overhead.In this work,a simplified BCH codec is proposed for reliable communication in NoC and SoC.It performs BCH error corrections without Berlekamp’s algorithm,only using reduced syndrome bits to determine error patterns.The error locations can be found by looking up tables,by which the possible errors are directly corrected.Only one matrix product and one ROM access are required in the BCH decoder.The proposed(20,8,2)and(31,16,3)decoders in the paper can be easily applied for error corrections of interconnects and buses for NoC and SoC.It is also beneficial to correct data lines without length definition and control lines without storage. | WU Tao YANG Ailin | 2021 | Chinese Journal of Electronics2021，30，3： | 1 |

| 20 | Two-in-one strategy:a remineralizing and anti-adhesive coating against demineralized enamel显示文摘Tooth enamel is prone to be attacked by injurious factors,leading to a de/remineralization imbalance.To repair demineralized enamel and prevent pulp inflammation caused by biofilm accumulation,measures are needed to promote remineralization and inhibit bacterial adhesion on the tooth surface.An innovative material,poly(aspartic acid)-polyethylene glycol(PASP-PEG),was designed and synthesized to construct a mineralizing and anti-adhesive surface that could be applied to repair demineralized enamel.A cytotoxicity assay revealed the low cytotoxicity of synthesized PASP-PEG.Adsorption results demonstrated that PASPPEG possesses a high binding affinity to the hydroxyapatite(HA)/tooth surface.In vitro experiments and scanning electron microscopy(SEM)demonstrated a strong capacity of PASP-PEG to induce in situ remineralization and direct the oriented growth of apatite nanocrystals.Energy dispersive X-ray spectroscopy(EDS),X-ray diffraction analysis(XRD)and Vickers hardness tests demonstrated that minerals induced by PASP-PEG were consistent with healthy enamel in Ca/P ratio,crystal form and surface micro-hardness.Contact angle tests and bacterial adhesion experiments demonstrated that PASP-PEG yielded a strong antiadhesive effect.In summary,PASP-PEG could achieve dual effects for enamel repair and anti-adhesion of bacteria,thereby widening its application in enamel repair. | Ailin Hou Jun Luo Min Zhang Jianshu Li Wenlin Chu Kunneng Liang Jiaojiao Yang Jiyao Li | 2020 | International Journal of Oral Science2020，12，3： | 0 |
