1Progress in Semi-arid Climate Change Studies in China显示文摘This article reviews recent progress in semi-arid climate change research in China.Results indicate that the areas of semiarid regions have increased rapidly during recent years in China,with an increase of 33%during 1994-2008 compared to 1948-62.Studies have found that the expansion rate of semi-arid areas over China is nearly 10 times higher than that of arid and sub-humid areas,and is mainly transformed from sub-humid/humid regions.Meanwhile,the greatest warming during the past 100 years has been observed over semi-arid regions in China,and mainly induced by radiatively forced processes.The intensity of the regional temperature response over semi-arid regions has been amplified by land-atmosphere interactions and human activities.The decadal climate variation in semi-arid regions is modulated by oceanic oscillations,which induce land-sea and north-south thermal contrasts and affect the intensities of westerlies,planetary waves and blocking frequencies.In addition,the drier climates in semi-arid regions across China are also associated with the weakened East Asian summer monsoon in recent years.Moreover,dust aerosols in semi-arid regions may have altered precipitation by affecting the local energy and hydrological cycles.Finally,semi-arid regions in China are projected to continuously expand in the 21st century,which will increase the risk of desertification in the near future.Jianping HUANG Jieru MA Xiaodan GUAN Yue LI Yongli HE 2019Advances in Atmospheric Sciences2019,36,9:15
2Pd/activated carbon sorbents for mid-temperature capture of mercury from coal-derived fuel gas显示文摘Higher concentrations of Hg can be emitted from coal pyrolysis or gasification than from coal combustion, especially elemental Hg. Highly efficient Hg removal technology from coal-derived fuel gas is thus of great importance. Based on the very excellent Hg removal ability of Pd and the high adsorption abilities of activated carbon(AC) for H2 S and Hg, a series of Pd/AC sorbents was prepared by using pore volume impregnation, and their performance in capturing Hg and H2 S from coal-derived fuel gas was investigated using a laboratory-scale fixed-bed reactor. The effects of loading amount, reaction temperature and reaction atmosphere on Hg removal from coal-derived fuel gas were studied. The sorbents were characterized by N2 adsorption, X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS). The results indicated that the efficiency of Hg removal increased with the increasing of Pd loading amount, but the effective utilization rate of the active component Pd decreased significantly at the same time. High temperature had a negative influence on the Hg removal. The efficiency of Hg removal in the N2–H2S–H2–CO–Hg atmosphere(simulated coal gas) was higher than that in N2–H2S–Hg and N2–Hg atmospheres, which showed that H2 and CO, with their reducing capacity, could benefit promote the removal of Hg. The XPS results suggested that there were two different ways of capturing Hg over sorbents in N2–H2S–Hg and N2–Hg atmospheres.Dekui Li Jieru Han Lina Han Jiancheng Wang Liping Chang 2014Journal of Environmental Sciences2014,26,7:8
3Discovery of fossil monocotyledons from Yixian Formation, western Liaoning显示文摘This is the first reports of a few fossil monocotyledons, including \%Liaoxia chenii\% gen. et sp. nov. (belonging to Cyperaceae), \%Eragrosites changii\% gen. et sp. nov. (Gramineae) and a monocotyledonous leaf_shoot, obtained from the Late Jurassic Yixian Formation of western Liaoning Province, NE China. These fossils are the oldest known angiosperms in the world. It may be inferred that the earliest angiosperms probably appeared even earlier than the Late Jurassic.Zhengyao Cao Shunqing Wu Ping’an Zhang Jieru Li 1998Chinese Science Bulletin1998,43,3:5

8Femtosecond laser fabrication of nanograting-based distributed fiber sensors for extreme environmental applications显示文摘The femtosecond laser has emerged as a powerful tool for micro-and nanoscale device fabrication. Through nonlinear ionization processes, nanometer-sized material modifications can be inscribed in transparent materials for device fabrication. This paper describes femtosecond precision inscription of nanograting in silica fiber cores to form both distributed and point fiber sensors for sensing applications in extreme environmental conditions. Through the use of scanning electron microscope imaging and laser processing optimization,high-temperature stable, Type II femtosecond laser modifications were continuously inscribed,point by point, with only an insertion loss at 1 d B m~(-1) or 0.001 d B per point sensor device.High-temperature performance of fiber sensors was tested at 1000℃, which showed a temperature fluctuation of ±5.5℃ over 5 days. The low laser-induced insertion loss in optical fibers enabled the fabrication of a 1.4 m, radiation-resilient distributed fiber sensor. The in-pile testing of the distributed fiber sensor further showed that fiber sensors can execute stable and distributed temperature measurements in extreme radiation environments. Overall, this paper demonstrates that femtosecond-laser-fabricated fiber sensors are suitable measurement devices for applications in extreme environments.Mohan Wang Kehao Zhao Jingyu Wu Yuqi Li Yang Yang Sheng Huang Jieru Zhao Thomas Tweedle David Carpenter Guiqiu Zheng Qingxu Yu Kevin P Chen 2021International Journal of Extreme Manufacturing2021,3,2:1
9A hybrid Wavelet-CNN-LSTM deep learning model for short-term urban water demand forecasting显示文摘Short-term water demand forecasting provides guidance on real-time water allocation in the water supply network, which help water utilities reduce energy cost and avoid potential accidents. Although a variety of methods have been proposed to improve forecast accuracy, it is still difficult for statistical models to learn the periodic patterns due to the chaotic nature of the water demand data with high temporal resolution. To overcome this issue from the perspective of improving data predictability, we proposed a hybrid Wavelet-CNN-LSTM model, that combines time-frequency decomposition characteristics of Wavelet Multi-Resolution Analysis (MRA) and implement it into an advanced deep learning model, CNN-LSTM. Four models - ANN, Conv1D, LSTM, GRUN - are used to compare with Wavelet-CNN-LSTM, and the results show that Wavelet-CNN-LSTM outperforms the other models both in single-step and multi-steps prediction. Besides, further mechanistic analysis revealed that MRA produce significant effect on improving model accuracy.Zhengheng Pu Jieru Yan Lei Chen Zhirong Li Wenchong Tian Tao Tao Kunlun Xin 2023Frontiers of Environmental Science & Engineering2023,17,2:1
10Review of stopping power and Coulomb explosion for molecular ion in plasmas显示文摘We summarize our theoretical studies for stopping power of energetic heavy ion,diatomic molecular ions and small clusters penetrating through plasmas.As a relevant research field for the heavy ion inertial confinement fusion(HICF),we lay the emphasis on the dynamic po-larization and correlation effects of the constituent ion within the molecular ion and cluster for stopping power in order to disclose the role of the vicinage effect on the Coulomb explosion and energy deposition of molecules and clusters in plasma.On the other hand,as a promising scheme for ICF,both a strong laser field and an intense ion beam are used to irradiate a plasma target.So the influence of a strong laser field on stopping power is significant.We discussed a large range of laser and plasma parameters on the coulomb explosion and stopping power for correlated-ion cluster and C 60 cluster.Furthermore,in order to indicate the effects of different cluster types and sizes on the stopping power,a comparison is made for hydrogen and carbon clusters.In addition,the deflection of molecular axis for diatomic molecules during the Coulomb explosion is also given for the cases both in the presence of a laser field and laser free.Finally,a future experimental scheme is put forward to measure molecular ion stopping power in plasmas in Xi’an Jiaotong University of China.Guiqiu Wang He Yi Yujiao Li Yaochuan Wang Dajun Liu Fei Gao Wei Liu Jieru Ren Xing Wang Yongtao Zhao Younian Wang 2018Matter and Radiation at Extremes2018,3,2:1

14A novel and low-toxic peptide DR3penA alleviates pulmonary fibrosis by regulating the MAPK/miR-23b-5p/AQP5 signaling axis显示文摘Pulmonary fibrosis(PF)is a pathological change caused by repeated injuries and repair dysfunction of the alveolar epithelium.Our previous study revealed that the residues Asn3 and Asn4 of peptide DR8(DHNNPQIR-NH_(2))could be modified to improve stability and antifibrotic activity,and the unnatural hydrophobic amino acids a-(4-pentenyl)-Ala and D-Ala were considered in this study.DR3penA(DHa-(4-pentenyl)-ANPQIR-NH_(2))was verified to have a longer half-life in serum and to significantly inhibit oxidative damage,epithelial-mesenchymal transition(EMT)and fibrogenesis in vitro and in vivo.Moreover,DR3penA has a dosage advantage over pirfenidone through the conversion of drug bioavailability under different routes of administration.A mechanistic study revealed that DR3penA increased the expression of aquaporin 5(AQP5)by inhibiting the upregulation of miR-23b-5p and the mitogen-activated protein kinase(MAPK)pathway,indicating that DR3penA may alleviate PF by regulating MAPK/miR-23b-5p/AQP5.Safety evaluation showed that DR3penA is a peptide drug without obvious toxicity or acute side effects and has significantly improved safety compared to DR8.Thus,our findings suggest that DR3penA,as a novel and low-toxic peptide,has the potential to be a leading compound for PF therapy,which provides a foundation for the development of peptide drugs for fibrosis-related diseases.Dan Wang Bochuan Deng Lu Cheng Jieru Li Jiao Zhang Xiang Zhang Xiaomin Guo Tiantian Yan Xin Yue Yingying An Bangzhi Zhang Wenle Yang Junqiu Xie Rui Wang 2023Acta Pharmaceutica Sinica B2023,13,2:0
