| 1 | Dynamics of ecosystem carbon stocks during vegetation restoration on the Loess Plateau of China显示文摘In the last few decades, the Loess Plateau had experienced an extensive vegetation restoration to reduce soil erosion and to improve the degraded ecosystems. However, the dynamics of ecosystem carbon stocks with vegetation restoration in this region are poorly understood. This study examined the changes of carbon stocks in mineral soil(0–100 cm), plant biomass and the ecosystem(plant and soil) following vegetation restoration with different models and ages. Our results indicated that cultivated land returned to native vegetation(natural restoration) or artificial forest increased ecosystem carbon sequestration. Tree plantation sequestered more carbon than natural vegetation succession over decades scale due to the rapid increase in biomass carbon pool. Restoration ages had different effects on the dynamics of biomass and soil carbon stocks. Biomass carbon stocks increased with vegetation restoration age, while the dynamics of soil carbon stocks were affected by sampling depth. Ecosystem carbon stocks consistently increased after tree plantation regardless of the soil depth; but an initial decrease and then increase trend was observed in natural restoration chronosequences with the soil sampling depth of 0–100 cm. Moreover, there was a time lag of about 15–30 years between biomass production and soil carbon sequestration in 0–100 cm, which indicated a long-term effect of vegetation restoration on deeper soil carbon sequestration. | WANG Kaibo DENG Lei REN Zongping SHI Weiyu CHEN Yiping SHANG-GUAN Zhouping | 2016 | Journal of Arid Land2016，8，2： | 7 |
| 2 | Thickness of calcium carbonate coats on stones of the Heishanxia terraces of the Yellow River and dating of coarse clastic sedimentary geomorphic surfaces显示文摘The calcium carbonate coats on stones developed in soil on the geomorphic surfaces of coarse clastic sediments in arid-semiarid regions contain evident information of age. The thickness of coats can be used not only as a good age indicator for the geomorphic surfaces but also coats themselves can be directly used as dating materials in the ESR method. Through measuring the thickness of carbonate coats on stones in soils on the alluvial terraces in the mouth of the Heishanxia gorge of the Yellow River and ESR dating of layers separated from the carbonate coats, the average of accumulation rates of the thickness of carbonate coats on stones since 1.57 Ma was calculated to be 0.10 mm/ka in the studied area, and a regression equation between carbonate coat thickness and age was also generated. From these research results, ages of T2-T11 terraces of the Yellow River in the studied area were systematically determined, and their values are in turn 18 ka, 94 ka, 139 ka, 215 ka, 305 ka, 410 ka, 495 ka, 742 ka, | Chengqi Xing Gongming Yin Guoyu Ding Yanchou Lu Xuhui Shen Qinjian Tian Zhizhang Chai Kaibo Wei | 2002 | Chinese Science Bulletin2002，47，19： | 7 |

| 4 | Exosomes rewire the cartilage microenvironment in osteoarthritis:from intercellular communication to therapeutic strategies显示文摘Osteoarthritis(OA)is a prevalent degenerative joint disease characterized by cartilage loss and accounts for a major source of pain and disability worldwide.However,effective strategies for cartilage repair are lacking,and patients with advanced OA usually need joint replacement.Better comprehending OA pathogenesis may lead to transformative therapeutics.Recently studies have reported that exosomes act as a new means of cell-to-cell communication by delivering multiple bioactive molecules to create a particular microenvironment that tunes cartilage behavior.Specifically,exosome cargos,such as noncoding RNAs(ncRNAs)and proteins,play a crucial role in OA progression by regulating the proliferation,apoptosis,autophagy,and inflammatory response of joint cells,rendering them promising candidates for OA monitoring and treatment.This review systematically summarizes the current insight regarding the biogenesis and function of exosomes and their potential as therapeutic tools targeting cell-to-cell communication in OA,suggesting new realms to improve OA management. | Yuangang Wu Jiao Li Yi Zeng Wenchen Pu Xiaoyu Mu Kaibo Sun Yong Peng Bin Shen | 2022 | International Journal of Oral Science2022，14，3： | 4 |
| 5 | Simulating the vegetation-producing process in small watersheds in the Loess Plateau of China显示文摘Small watersheds are the basic composition unit of the Loess Plateau in China. An accurate estimation of vegetation net primary productivity (NPP) is of great significance for eco-benefit evaluation in small watershed management in this region. Here we describe the development and testing of a vegetation-producing process model (VPP) of a small watershed in the Loess Plateau. The model couples three modules: radiation adjustment; soil hydrological processes; and vegetation carbon assimilation. Model validation indicates that the VPP model can be used to estimate the NPP of small watersheds in the region. With the VPP model, we estimated the spatial NPP distributions in the Yangou watershed for 2007. The results show that in the Yangou watershed the NPP is relatively low, averaging 168 g C/(m 2 ·a). Trees and shrubs have a higher NPP than crops and grasses. The NPP is larger on the partly shaded and shaded slopes than on the partly sunny and sunny slopes. The NPP on the slopes increases gradually on 0-20° slopes and decreases slightly on slopes steeper than 20°. Our simulation indicates that the vegetation type is the most important factor in determining the NPP distribution in small watersheds in the Loess Plateau. | KaiBo WANG ZhouPing SHANGGUAN | 2012 | Journal of Arid Land2012，4，3： | 3 |
| 6 | Carbon inputs regulate the temperature sensitivity of soil respiration in temperate forests显示文摘Litter and root activities may alter the temperature sensitivity(Q_(10))of soil respiration.However,existing studies have not provided a comprehensive understanding of the effects of litter and root carbon inputs on the Q_(10)of soil respiration in different seasons.In this study,we used the trench method under in situ conditions to measure the total soil respiration(R_(total)),litter-removed soil respiration(R_(no-litter)),root-removed soil respiration(R_(no-root)),and the decomposition of soil organic matter(i.e.,both litter and root removal;R_(SOM))in different seasons of pioneer(Populus davidiana Dode)and climax(Quercus liaotungensis Mary)forests on the Loess Plateau,China.Soil temperature,soil moisture,litter biomass,fine root biomass,litter carbon,and root carbon were analyzed to obtain the drive mechanism of the Q_(10)of soil respiration in the two forests.The results showed that the Q_(10)of soil respiration exhibited seasonality,and the Q_(10)of soil respiration was higher in summer.The litter enhanced the Q_(10)of soil respiration considerably more than the root did.Soil temperature,soil moisture,fine root biomass,and litter carbon were the main factors used to predict the Q_(10)of different soil respiration components.These findings indicated that factors affecting the Q_(10)of soil respiration highly depended on soil temperature and soil moisture as well as related litter and root traits in the two forests,which can improve our understanding of soil carbon–climate feedback in global warming.The results of this study can provide reference for exploring soil respiration under temperate forest restoration. | LIU Yulin LI Jiwei HAI Xuying WU Jianzhao DONG Lingbo PAN Yingjie SHANGGUAN Zhouping WANG Kaibo DENG Lei | 2022 | Journal of Arid Land2022，14，9： | 3 |
| 7 | AI-Based Optimization of Handover Strategy in Non-Terrestrial Networks显示文摘Complicated radio resource management,e.g.,handover condition,will trouble the user in non-terrestrial networks due to the impact of high mobility and hierarchical layouts which co-exist with terrestrial networks or various platforms at different altitudes.It is necessary to optimize the handover strategy to reduce the signaling overhead and im⁃prove the service continuity.In this paper,a new handover strategy is proposed based on the convolutional neural network.Firstly,the handover process is modeled as a directed graph.Suppose a user knows its future signal strength,then he/she can search for the best handover strategy based on the graph.Secondly,a convolutional neural network is used to extract the underlying regularity of the best handover strategies of different users,based on which any user can make near-optimal handover decisions according to its historical signal strength.Numerical simulation shows that the proposed handover strategy can effi⁃ciently reduce the handover number while ensuring the signal strength. | ZHANG Chenchen ZHANG Nan CAO Wei TIAN Kaibo YANG Zhen | 2021 | ZTE Communications2021，19，4： | 3 |

| 9 | Formamidinium Lead Bromide (FAPbBr_3) Perovskite Microcrystals for Sensitive and Fast Photodetectors显示文摘Because of the good thermal stability and superior carrier transport characteristics of formamidinium lead trihalide perovskite HC(NH_2)_2 PbX_3(FAPbX_3), it has been considered to be a better optoelectronic material than conventional CH_3NH_3-PbX_3(MAPbX_3). Herein, we fabricated a FAPbBr_3 microcrystal-based photodetector that exhibited a good responsivity of 4000 A W-1 and external quantum efficiency up to 106% under one-photon excitation, corresponding to the detectivity greater than 1014 Jones. The responsivity is two orders of magnitude higher than that of previously reported formamidinium perovskite photodetectors. Furthermore, the FAPbBr_3 photodetector's responsivity to two-photon absorption with an 800-nm excitation source can reach 0.07 A W^(-1), which is four orders of magnitude higher than that of its MAPbBr_3 counterparts. The response time of this photodetector is less than 1 ms.This study provides solid evidence that FAPbBr_3 can be an excellent candidate for highly sensitive and fast photodetectors. | Fengying Zhang Bin Yang Kaibo Zheng Songqiu Yang Yajuan Li Weiqiao Deng Rongxing He | 2018 | Nano-Micro Letters2018，10，3： | 2 |

| 11 | A time domain induced polarization relaxation time spectrum inversion method based on a damping factor and residual correction显示文摘Relaxation time spectra(RTS) derived from time domain induced polarization data(TDIP) are helpful to assess oil reservoir pore structures. However, due to the sensitivity to the signal-to-noise ratio(SNR), the inversion accuracy of the traditional singular value decomposition(SVD) inversion method reduces with a decrease of SNR. In order to enhance the inversion accuracy and improve robustness of the inversion method to the SNR, an improved inversion method, based on damping factor and spectrum component residual correction, is proposed in this study. The numerical inversion results show that the oscillation of the RTS derived from the SVD method increased with a decrease of SNR, which makes it impossible to get accurate inversion components. However, the SNR has little influence on inversion components of the improved method, and the RTS has high inversion accuracy and robustness. Moreover, RTS derived from core sample data is basically in accord with the pore-size distribution curve, and the RTS derived from the actual induced polarization logging data is smooth and continuous, which indicates that the improved method is practicable. | Liu Xiaonan Kong Li Zhou Kaibo Zhang Pu | 2014 | Petroleum Science2014，11，4： | 2 |

| 17 | Generation and functional characterization of a conditional Pumilio2 null allele显示文摘The highly conserved RNA binding protein PUF(Pumilio/FBF) family is present throughout eukaryotes from yeast to mammals, with critical roles in development, fertility and the nervous system. However, the function of the mammalian PUF family members remains underexplored. Our previous study reported that a gene-trap mutation of Purm2 results in a smaller testis but does not impact fertility and viability. Although the gene-trap mutation disrupted the key functional domain of PUM protein-PUM-HD(Pumilio homology domain), but still produced a chimeric Pum2-β-geo protein containing part of PUM2, raising a question if such a chimeric protein may provide any residual function or contribute to the reproductive phenotype. Here, we report the generation of a conditional PUM2 allele,when knocked out, producing no residual PUM2 and hence a complete loss-of-function allele. We also uncovered small but significant reduction of male fertility and viability in the mutants, suggesting requirement of PUM2 for male fertility and viability. | Kaibo Lin Shikun Zhang Jieli Chen Ding Yang Mengyi Zhu Eugene Yujun Xu | 2018 | The Journal of Biomedical Research2018，32，6： | 1 |

| 19 | Acoustics Based Monitoring and Diagnostics for the Progressive Deterioration of Helical Gearboxes显示文摘Gearbox condition monitoring(CM)plays a significant role in ensuring the operational reliability and efficiency of a wide range of critical industrial systems such as wind turbines and helicopters.Accurate and timely diagnosis of gear faults will improve the maintenance of gearboxes operating under sub-optimal conditions,avoid excessive energy consumption and prevent avoidable damages to systems.This study focuses on developing CM for a multi-stage helical gearbox using airborne sound.Based on signal phase alignments,Modulation Signal Bispectrum(MSB)analysis allows random noise and interrupting events in sound signals to be suppressed greatly and obtains nonlinear modulation features in association with gear dynamics.MSB coherence is evaluated for selecting the reliable bi-spectral peaks for indication of gear deterioration.A run-to-failure test of two industrial gearboxes was tested under various loading conditions.Two omnidirectional microphones were fixed near the gearboxes to sense acoustic information during operation.It has been shown that compared against vibration based CM,acoustics can perceive the responses of vibration in a larger areas and contains more comprehensive and stable information related to gear dynamics variation due to wear.Also,the MSB magnitude peaks at the first three harmonic components of gear mesh and rotation components are demonstrated to be sufficient in characterizing the gradual deterioration of gear transmission.Consequently,the combining of MSB peaks with baseline normalization yields more accurate monitoring trends and diagnostics,allowing the gradual deterioration process and gear wear location to be represented more consistently. | Kaibo Lu James Xi Gu Hongwei Fan Xiuquan Sun Bing Li Fengshou Gu | 2021 | Chinese Journal of Mechanical Engineering2021，34，4： | 1 |
