| 2 | The Y.D.and climate abrupt events in the early and middle Holocene:Stalagmite oxygen isotope record from Maolan,Guizhou,China显示文摘The isotope records which range from 3.9 kaBP to 15.7 kaBP with an average resolution of 90 a have been obtained from 45 cm to 193.6 cm of the upper part of D4 stalagmite from Dongguo Cave in Libo, Guizhou, by using system TIMS U-series dating and carbon and oxygen stable isotope analyses.The study indicates that the last cold event, the YD (Younger Dryas) event, of the last glacial period was apparently shown in D4 record, which started from 12.80 kaBP and ended in 11.58 kaBP, with a great range of drop in temperature. The end of the last glacial period was consistent with the termination I in oceanic isotope records and was with time limit of 11.3 kaBP. The three most distinct cold events in the early and middle Holocene occurred respectively in 10.91 kaBP, 8.27 kaBP and 4.75 kaBP, with a range of drop in tem- perature reaching 2—5℃. The climate abrupt events in thousand and hundred years scale re- corded in stalagmite δ O can be compared to those in GISP2 ice cores from Greenland in their 18 happening time and the range of their lasting time. The cold events in 8.27 kaBP and 4.75 kaBP can also be compared to CC3 stalagmite records in Ireland, which indicate that climate changes of short range in China monsoon areas, western Europe and polar regions, have the same driv- ing factor. This has a global significance. In addition, the trend of record curves in some time- stages is apparently different, which reflects probably the difference between environment in monsoon climate areas and in polar regions. | QIN Jiaming1, YUAN Daoxian1, CHENG Hai2, LIN Yushi1, ZHANG Meiliang1, WANG Fuxing1, R.

| 3 | Demand Response Based and Wind Farm Integrated Economic Dispatch显示文摘Increased penetration of intermittent renewable energy resources is pushing the grid to prepare more reserves to meet the supply and demand balance.Demand response(DR)is an efficient strategy to reduce the overall load at peak times.In order to fully utilize the application of DR and make DR capable of actively supporting grid operations at all times,this paper builds a DR and wind farm integrated economic dispatch model.The objective is to minimize the total operation costs,such as fuel cost,startup cost,greenhouse gas(GHG)emission costs,and DR cost.DR maximum participating time and DR ramp rate constraints are considered.A system with 10 traditional units,one large-scale wind farm,three types of DR,including interruptible load,direct load control,and load as capacity resource are selected to verify the proposed model.Four DR penetration rates are analyzed:0%,10%,20%and 30%.The results indicate that DR penetration can decrease total operation costs.The lower price DR resource gets the priority to be committed.The DR and wind farm integration is indispensable in the future economic dispatch. | Haijun Xing Haozhong Cheng Libo Zhang | 2015 | CSEE Journal of Power and Energy Systems2015，1，4： | 15 |
| 4 | Modeling the global ionospheric total electron content with empirical orthogonal function analysis显示文摘In the present work we model the global ionospheric total electron content (TEC) with the analysis of empirical orthogonal functions (EOF). The obtained statistical eigen modes, which makeup the modeled TEC, consist of two factors: the eigen vectors mapping TEC patterns at latitude and longitude (or local time LT), and the corresponding coefficients displaying the TEC variations in different time scales, i.e., the solar cycle, the yearly (annual and semiannual) and the diurnal universal time variations. It is found that the EOF analysis can separate the TEC variations into chief processes and the first two modes illustrate the most of the ionospheric climate properties. The first mode contains both the semiannual component which shows the semiannual ionospheric anomaly and the annual component which shows the annual or non-seasonal ionospheric anomaly. The second mode contains mainly the annual component and shows the normal seasonal ionospheric variation at most latitudes and local time sectors. The annual component in the second mode also manifests seasonal anomaly of the ionosphere at higher mid-latitudes around noontime. It is concluded that the EOF analysis, as a statistical eigen mode method, is resultful in analyzing the ionospheric climatology hence can be used to construct the empirical model for the ionospheric climatology. | WAN WeiXing DING Feng REN ZhiPeng ZHANG ManLian LIU LiBo NING BaiQi | 2012 | Science China(Technological Sciences)2012，55，5： | 15 |
| 5 | Sea surface temperature records of core ZY2 from the central mud area in the South Yellow Sea during last 6200 years and related effect of the Yellow Sea Warm Current显示文摘Sea surface temperature (SST) records in the South Yellow Sea during the last 6200 years are reconstructed by the unsaturation index of long-chain alkenones (K 37 U ') in sediment core ZY2 from the central mud area.The SST records varied between 14.1 and 16.5°C (15.6°C on average),with 3 phases:(1) A high SST phase at 6.2-5.9 cal ka BP;(2) A low and intensely fluctuating SST phase at 5.9-2.3 cal ka BP;and (3) A high and stable SST phase since 2.3 cal ka BP.Variation of the SST records is similar to intensity of the Kuroshio Current (KC),and corresponds well in time to global cold climate events.However,the amplitude of the SST response to cooling events was significantly different in different phases.The SST response to global cooling event was weak while the KC was strong;and the SST response was strong while the KC was weak.The difference in amplitude of the SST response is possibly caused by the modulation effect of the Yellow Sea Warm Current which acts as a shelf branch of the KC and a compensating current induced by the East Asia winter monsoon.The warm waters brought by the Yellow Sea Warm Current cushion the SST decrease induced by climate cooling,and both the Kuroshio and East Asian winter monsoon play important roles in the modulation mechanism.The SST records display a periodicity of 1482 years.The same period was found in the KC records,indicating that variation of the SST records in the central South Yellow Sea is strongly affected by KC intensity.The same period was also found in Greenland ice cores and North Atlantic and Arabian Sea sediment cores,showing a regional response of marine environmental variability in the East China Seas to that in the global oceans. | WANG LiBo YANG ZuoSheng ZHANG RongPing FAN DeJiang ZHAO MeiXun HU BangQi | 2011 | Chinese Science Bulletin2011，56，15： | 13 |

| 7 | Electrochemical performance of Ti_(3)C_(2)supercapacitors in KOH electrolyte显示文摘Two-dimensional(2D)carbide Ti_(3)C_(2)was synthesized by exfoliating Ti_(3)AlC_(2)in HF solution and used for supercapacitive performance investigation in 3 M KOH electrolyte.The specific surface area(SSA)of as-synthesized Ti_(3)C_(2)was 22.35 m^(2)/g.Ti_(3)C_(2)-based supercapacitor electrodes exhibited good energy storage ability and had a volumetric capacitance 119.8 F/cm^(3)at the current density of 2.5 A/g.Moreover,the addition of carbon black into Ti_(3)C_(2)powders greatly improved the performance of Ti_(3)C_(2)-based capacitors because carbon black restrained the preferred orientation of 2D Ti_(3)C_(2),providing fast ion transport channels,and in turn,decreasing electrical resistance from 16.7Ωto 3.5Ω. | Yupeng GAO Libo WANG Zhengyang LI Yafei ZHANG Baolin XING Chuanxiang ZHANG Aiguo ZHOU | 2015 | Journal of Advanced Ceramics2015，4，2： | 10 |
| 8 | Finite p-Groups all of Whose Subgroups of Index p^(3) are Abelian显示文摘Suppose that G is a finite p-group.If all subgroups of index p^(t)of G are abelian and at least one subgroup of index p^(t−1)of G is not abelian,then G is called an A_(t)-group.We useA0-group to denote an abelian group.From the definition,we know every finite non-abelian p-group can be regarded as an A_(t)-group for some positive integer t.A_(1)-groups and A_(2)-groups have been classified.Classifying A_(3)-groups is an old problem.In this paper,some general properties about A_(t)-groups are given.A_(3)-groups are completely classified up to isomorphism.Moreover,we determine the Frattini subgroup,the derived subgroup and the center of every A_(3)-group,and give the number of A_(1)-subgroups and the triple(μ_(0),μ_(1),μ_(2))of every A_(3)-group,whereμi denotes the number of A_(i)-subgroups of index p of A_(3)-groups. | Qinhai Zhang Libo Zhao Miaomiao Li Yiqun Shen | 2015 | Communications in Mathematics and Statistics2015，3，1： | 9 |
| 9 | Synergistic effects of non-thermal plasma-assisted catalyst and ultrasound on toluene removal显示文摘A wire-mesh catalyst coated by La0.8Sr0.2MnO3 was combined with a dielectric barrier discharge (DBD) reactor for toluene removal at atmospheric pressure. It was found that toluene removal efficiency and carbon dioxide selectivity were enhanced in the catalytic packed-bed reactor. In addition, ozone and nitrogen monoxide from the gas effluent byproducts decreased. This is the first time that ultrasound combined with plasma has been used for toluene removal. A synergistic effect on toluene removal was observed in the plasma-assisted ultrasound system. At the same time, the system increased toluene conversion and reduced ozone emission. | Yongli Sun Libo Zhou Luhong Zhang Hong Sui | 2012 | Journal of Environmental Sciences2012，24，5： | 9 |
| 10 | Actively priming autophagic cell death with novel transferrin receptor-targeted nanomedicine for synergistic chemotherapy against breast cancer显示文摘Recently, considerable attention in the field of cancer therapy has been focused on the mammalian rapamycin target(m TOR), inhibition of which could result in autophagic cell death(ACD). Though novel combination chemotherapy of autophagy inducers with chemotherapeutic agents is extensively investigated, nanomedicine-based combination therapy for ACD remains in infancy. In attempt to actively trigger ACD for synergistic chemotherapy, here we incorporated autophagy inducer rapamycin(RAP) into 7 pep-modified PEG-DSPE polymer micelles(7 pep-M-RAP) to specifically target and efficiently priming ACD of MCF-7 human breast cancer cells with high expression of transferrin receptor(Tf R). Cytotoxic paclitaxel(PTX)-loaded micelle(7 pep-M-PTX) was regarded as chemotherapeutic drug model. We discovered that with superior intracellular uptake in vitro and more tumor accumulation of micelles in vivo, 7 pep-M-RAP exhibited excellent autophagy induction and synergistic antitumor efficacy with 7 pep-M-PTX. Mechanism study further revealed that 7 pep-M-RAP and 7 pep-MPTX used in combination provided enhanced efficacy through induction of both apoptosis-and mitochondria-associated autophagic cell death. Together, our findings suggested that the targeted excess autophagy may provide a rational strategy to improve therapeutic outcome of breast cancer, and simultaneous induction of ACD and apoptosis may be a promising anticancer modality. | Dong Mei Binlong Chen Bing He Haibin Liu Zhiqiang Lin Jialiang Lin Xiaoyan Zhang Ning Sun Libo Zhao Xiaoling Wang Qiang Zhang | 2019 | Acta Pharmaceutica Sinica B2019，9，5： | 8 |
| 11 | Comparison of activated carbon and iron/cerium modified activated carbon to remove methylene blue from wastewater显示文摘The methylene blue(MB)removal abilities of raw activated carbon and iron/cerium modified raw activated carbon(Fe–Ce-AC)by adsorption were researched and compared.The characteristics of Fe–Ce-AC were examined by N_2adsorption,zeta potential measurement,FTIR,Raman,XRD,XPS,SEM and EDS.After modification,the following phenomena occurred:The BET surface area,average pore diameter and total pore volume decreased;the degree of graphitization also decreased.Moreover,the presence of Fe_3O_4led to Fe–Ce-AC having magnetic properties,which makes it easy to separate from dye wastewater in an external magnetic field and subsequently recycle.In addition,the equilibrium isotherms and kinetics of MB adsorption on raw activated carbon and Fe–Ce-AC were systematically examined.The equilibrium adsorption data indicated that the adsorption behavior followed the Langmuir isotherm,and the pseudo-second-order model matched the kinetic data well.Compared with raw activated carbon,the maximum monolayer adsorption capacity of Fe–Ce-AC increased by27.31%.According to the experimental results,Fe–Ce-AC can be used as an effective adsorbent for the removal of MB from dye wastewater. | Song Cheng Libo Zhang Aiyuan Ma Hongying Xia Jinhui Peng Chunyang Li Jianhua Shu | 2018 | Journal of Environmental Sciences2018，30，3： | 8 |
| 12 | Recent Advances in Self-Supported Layered Double Hydroxides for Oxygen Evolution Reaction显示文摘Electrochemical water splitting driven by clean and sustainable energy sources to produce hydrogen is an efficient and environmentally friendly energy conversion technology.Water splitting involves hydrogen evolution reaction(HER)and oxygen evolution reaction(OER),in which OER is the limiting factor and has attracted extensive research interest in the past few years.Conventional noble-metal-based OER electrocatalysts like IrO_(2) and RuO_(2) suffer from the limitations of high cost and scarce availability.Developing innovative alternative nonnoble metal electrocatalysts with high catalytic activity and long-term durability to boost the OER process remains a significant challenge.Among all of the candidates for OER catalysis,selfsupported layered double hydroxides(LDHs)have emerged as one of the most promising types of electrocatalysts due to their unique layered structures and high electrocatalytic activity.In this review,we summarize the recent progress on self-supported LDHs and highlight their electrochemical catalytic performance.Specifically,synthesis methods,structural and compositional parameters,and influential factors for optimizing OER performance are discussed in detail.Finally,the remaining challenges facing the development of self-supported LDHs are discussed and perspectives on their potential for use in industrial hydrogen production through water splitting are provided to suggest future research directions. | Libo Wu Luo Yu Xin Xiao Fanghao Zhang Shaowei Song Shuo Chen Zhifeng Ren | 2020 | Research2020，，1： | 7 |

| 15 | Historical Changes and Future Projections of Extreme Temperature and Precipitation along the Sichuan-Tibet Railway显示文摘Based on multiresource high-resolution in situ and satellite merged observations along with model simulations from the Coordinated Regional Climate Downscaling Experiment(CORDEX),this study first investigated historical changes in extreme temperature and precipitation during the period of 1979-2018 in areas along the Sichuan-Tibet Railway,and then projected the future changes in the frequency and intensity of extreme temperature and precipitation under the RCP(Representative Concentration Pathway)4.5 and 8.5 scenarios.This paper is expected to enhance our understanding of the spatiotemporal variability in the extreme temperature and precipitation along the Sichuan-Tibet Railway,and to provide scientific basis to advance the Sichuan-Tibet Railway construction and operation.The results show that temperatures in the Sichuan-Tibet region display a noticeable warming trend in the past 40 years,and the increase of minimum temperature is significantly higher than that of maximum temperature in the northwest of the region.Significant increase of precipitation is found mainly over the northwest of the Tibetan Plateau.Except for Lhasa and its surrounding areas,precipitation over other areas along the Sichuan-Tibet Railway shows no significant change in the past 40 years,as indicated in five datasets;however,precipitation along the railway has shown a remarkable decrease in the past 20 years in the TRMM satellite dataset.The warm days and nights have clearly increased by 6 and 5 day decade1-for 1979-2019,while cold days and nights have markedly decreased by about 6.6 and 3.6 day decade-1,respectively.In the past 20 years,the areas with increased precipitation from very wet days and extremely wet days are mainly distributed to the north of the Sichuan-Tibet Railway,while in the areas along the railway itself,the very wet days and extremely wet days are decreasing.Under RCPs 4.5 and 8.5,the temperature in the Sichuan-Tibet region will increase significantly,and the frequency of extreme high(low)temperature events in the late 21 st century(2070-2099)will greatly increase(decrease)by about 50%-80%(10%)compared with occurrences in the late 20 th century(1970-1999).Meanwhile,the frequency of very wet days and extremely wet days in the Sichuan-Tibet region will increase by about 2%-19% and 2%-5%,respectively,and the areas along the Sichuan-Tibet Railway will be affected by more extreme high temperature and extreme precipitation events. | Jingpeng ZHANG Tianbao ZHAO Libo ZHOU Lingkun RAN | 2021 | Journal of Meteorological Research2021，35，3： | 5 |

| 17 | Assessment of the individual and combined effects of Rht8 and Ppd-D1a on plant height, time to heading and yield traits in common wheat显示文摘Grain yield in cereal crops is a complex trait controlled by multiple genes and influenced by developmental processes and environment. Here we report the effects of alleles Rht8 and Ppd-D1 a on plant height, time to heading, and grain yield and its component traits. Association analysis and quantitative trait locus mapping using phenotypic data from 15 environments led to the following conclusions. First, both Rht8 and Ppd-D1 a reduce plant height. However, Ppd-D1 a but not Rht8 causes earlier heading.Second, both Rht8 and Ppd-D1 a promote grain yield and affect component traits. Their combined effects are substantially larger than those conferred by either allele alone.Third, promotion of grain yield by Rht8 and Ppd-D1 a is through increasing fertile spikelet number. We speculate that Rht8 and Ppd-D1 a act independently and additively in control of plant height, grain yield and yield component. Combination of the two alleles is desirable for adjusting plant height and enhancing grain yield and abiotic stress tolerance. | Kunpu Zhang Junjun Wang Huanju Qin Zhiying Wei Libo Hang Pengwei Zhang Matthew Reynolds Daowen Wang | 2019 | The Crop Journal2019，7，6： | 5 |
| 18 | Effects of purified zearalenone on selected immunological measurements of blood in post-weaning gilts显示文摘Zearalenone(ZEA), an estrogenic mycotoxin, is produced mainly by Fusarium fungi. Previous studies have indicated that acute ZEA exposure induced various damages in different species; however, its transparent hematotoxicity in female piglets at dietary levels of 1.1 to 3.2 mg/kg has not been shown. The present study was conducted to investigate the effects of dietary ZEA(1.1—3.2 mg/kg) on hematology, T lymphocyte subset, immunoglobulin, antibody titer, lymphocyte proliferation rate(LPR), and interleukin-2(IL-2) in peripheral blood of post-weaning gilts. A total of 20 female piglets(Landrace × Yorkshire × Duroc),weaned at 42 d with an average body weight of 10.36 ± 1.21 kg were used in the study. Female piglets were kept in a temperature controlled room, divided into four treatments, and fed a diet based on corn-soybean meal-fishmeal-whey, with an addition of 0, 1.1, 2.0, or3.2 mg/kg purified ZEA for 18 d ad libitum. Feed intake and refusal were measured daily and individual pigs were weighed weekly. Blood and serum samples were collected for selected immunological measurements. Female piglets fed different levels of dietary ZEA grew similarly with no difference in feed intake. Hematological values including leukocytes, platelets, lymphocytes, hematocrit, and mean corpuscular hemoglobin(MCH) decreased linearly(P < 0.05) as dietary ZEA increased. Female piglets fed diets containing 2.0 mg/kg ZEA or greater showed significantly decreased CD4+CD8+, CD4+, and CD4+/CD8^+ in comparison to the control(P < 0.05), whereas CD8^+ was significantly increased(P = 0.026) in the gilts which were fed the diet containing 3.2 mg/kg ZEA. Serum immunoglobulin G(IgG) and the antibody titer on d 18 were reduced linearly as dietary ZEA levels increased(P < 0.001). Linear decrease in LPR was observed(P < 0.05). Female piglets fed diets containing 2.0 mg/kg ZEA or more showed significantly decreased IL-2 in comparison to the control(P < 0.05). The results suggested that dietary ZEA at the levels of 1.1 to 3.2 mg/kg can induce different degrees of hematotoxicity and negatively affect immune function in female piglets. | Lijie Yang Weiren Yang Qiang Feng Libo Huang Guiguo Zhang Faxiao Liu Shuzhen Jiang Zaibin Yang | 2016 | Animal Nutrition2016，，3： | 5 |
