2Impacts of Land-use and Land-cover Changes on River Runoff in Yellow River Basin for Period of 1956–2012显示文摘River runoff is affected by many factors, including long-term effects such as climate change that alter rainfall-runoff relationships, and short-term effects related to human intervention(e.g., dam construction, land-use and land-cover change(LUCC)). Discharge from the Yellow River system has been modified in numerous ways over the past century, not only as a result of increased demands for water from agriculture and industry, but also due to hydrological disturbance from LUCC, climate change and the construction of dams. The combined effect of these disturbances may have led to water shortages. Considering that there has been little change in long-term precipitation, dramatic decreases in water discharge may be attributed mainly to human activities, such as water usage, water transportation and dam construction. LUCC may also affect water availability, but the relative contribution of LUCC to changing discharge is unclear. In this study, the impact of LUCC on natural discharge(not including anthropogenic usage) is quantified using an attribution approach based on satellite land cover and discharge data. A retention parameter is used to relate LUCC to changes in discharge. We find that LUCC is the primary factor, and more dominant than climate change, in driving the reduction in discharge during 1956–2012, especially from the mid-1980 s to the end-1990 s. The ratio of each land class to total basin area changed significantly over the study period. Forestland and cropland increased by about 0.58% and 1.41%, respectively, and unused land decreased by 1.16%. Together, these variations resulted in changes in the retention parameter, and runoff generation showed a significant decrease after the mid-1980 s. Our findings highlight the importance of LUCC to runoff generation at the basin scale, and improve our understanding of the influence of LUCC on basin-scale hydrology.WANG Fang GE Quansheng YU Qibiao WANG Huaxin XU Xinliang 2017Chinese Geographical Science2017,27,1:9
3Superior mesenteric venous thrombosis after laparoscopic radical resection of rectal cancer: a report of a rare case and literature review显示文摘Mesenteric venous thrombosis(MVT) is rare, but life-threatening. MVT is often characterized by occult and nonspecific signs and symptoms. Diagnosis requires a high index of clinical suspicion, and emergency surgery is necessary to optimize patient survival, especially in people aged more than 70 years. MVT is a rare but fatal complication after laparoscopic radical surgery for rectal cancer. This study reports a case of extensive intestinal ischemic infarction caused by acute MVT after laparoscopic radical surgery for rectal cancer in a 70-year-old male.Xinliang Jin Weijie Xue Yixiu Wang Qinkai Xue Zhiqi Gong Yongke Liu Zhaojian Niu Chengzhan Zhu 2018Oncology and Translational Medicine2018,4,6:9
4On-chip programmable pulse processor employing cascaded MZI-MRR structure显示文摘Optical pulse processor meets the urgent demand for high-speed,ultra wideband devices,which can avoid electrical confinements in various fields,e.g.,alloptical communication,optical computing technology,cohcrcnt control and microwave fields.To date,great efforts have been madc particularly in on-chip programmable pulse proccessing.Here,we experimentally demonstrate a programmable pulse proceesor employing 16cascaded Mach-Zehnder interferometer coupled microring resonator(MZI-MRR)structure based on silicon-oninsulator wafer.With micro-heaters loaded to the device,both amplitude and frequency tunings can be realized in each MZI-MRR unit.Thanks to its reconfigurability and integration ability,First,it can serve as a fractional differentiator whose tuning range is 0.51-2.23 with deviation no more than 7%.Second,the device can be tuned into a programmable optical filter whose bandwidth varies from 0.15to 0.97nm.The optical filter is also shape tunable.Especially,15-channel wavelength selective switches are generated.Yuhe ZHAO Xu WANG Dingshan GAO Jianji DONG Xinliang ZHANG 2019Frontiers of Optoelectronics2019,12,2:9
5Recent Progress of MXene-Based Nanomaterials in Flexible Energy Storage and Electronic Devices显示文摘The increasing demands for wearable electronics have stimulated the rapid development of flexible energy storage devices.MXenes are considered as promising flexible electrodes due to the ultrahigh volumetric specific capacitance,metallic conductivity,superior hydrophily,and rich surface chemistry.Qi Yang Yukun Wang Xinliang Li Hongfei Li Zifeng Wang Zijie Tang Longtao Ma Funian Mo Chunyi Zhi 2018Energy & Environmental Materials2018,1,4:8
6Concentration level and distribution of polycyclic aromatic hydrocarbons in soil and grass around Mt. Qomolangma, China显示文摘High mountains may serve as a condenser for persistent organic pollutants. In the present study, soil and grass samples from Mt. Qomolangma region, China were collected from 4600 to 5620 m a.s.l and were analyzed for polycyclic aromatic hydrocarbons (PAHs) to determine if they are concentrated at colder, more elevated sites and to evaluate their possible resources and fractionation. The total PAHs concentration in soil samples was < 600 ng g?1, the critical value to differentiate PAHs levels in remote and urban regions. This implied the PAHs levels at Mt. Qomolangma are relatively low and what one might expect in such a remote region of the world. These low values may represent a soil background for mid-latitude Northern Hemisphere soils away from the direct influence of an anthropogenic source. As for the distribution pattern, the low molecular weight PAHs were prone to accumulate at higher altitude, while the high molecular weight PAHs inversely related or unrelated with elevation. Based on high concentration of phenanthrene at elevated sample site and the ratios of individual PAHs, we deduced that home-heating combustion and vehicle emission may result in the constitution trait of PAHs in this mountain region. Monsoon traveling over India, Pakistan and other countries with dense population may carry contaminant to Mt. Qomolangma region.WANG XiaoPing YAO TanDong CONG ZhiYuan YAN XinLiang KANG ShiChang ZHANG Yong 2007Chinese Science Bulletin2007,52,10:8

8Impacts of Park Landscape Structure on Thermal Environment Using QuickBird and Landsat Images显示文摘Urban parks composed mostly of vegetation and water bodies can effectively mitigate the urban heat island effect. Many studies have investigated the cooling effects of urban parks; however, little attention has been given to park landscape structure. Based on landscape metrics, this study has explored the influences of the park landscape structure on its inner thermal environment, taking heavily urbanized Beijing Municipality in China as the study area. Three indices, including the percentage of landscape(PLAND), landscape shape index(LSI) and aggregation index(AI), were used to measure the composition and configuration characteristics of the landscape components inside the parks. The indices were calculated for five landscape types being interpreted from Quickbird images. Urban thermal conditions were measured using the land surface temperature(LST) derived from Landsat TM images. The results showed that the park LST had a negative relationship with the park size, but no significant relationship was found with park shape. For the park's interior landscape, however, the configuration and composition characteristics of the landscape components inside the park explained 70% of the park LST variance. The area percentage of water bodies and the aggregation index of woodland were identified as the key influencing characteristics. In addition, when the composition and configuration characteristics of the park landscape components were separately considered, the configuration characteristics(LSI and AI) explained approximately 54% of the variance in park LST, which was comparable with that explained by the composition characteristics(PLAND). Thus, this study suggested that an effective and practical way for urban cooling park design is the optimization of spatial configuration of landscape components inside the park.XU Xinliang CAI Hongyan QIAO Zhi WANG Liang JIN Cui GE Yaning WANG Luyao XU Fengjiao 2017Chinese Geographical Science2017,27,5:4
9DESIGN OF QUASI-CYCLIC LDPC CODES BASED ON EUCLIDEAN GEOMETRIES显示文摘A new method for constructing Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes based on Euclidean Geometry (EG) is presented. The proposed method results in a class of QC-LDPC codes with girth of at least 6 and the designed codes perform very close to the Shannon limit with iterative decoding. Simulations show that the designed QC-LDPC codes have almost the same performance with the existing EG-LDPC codes.Liu Yuanhua Niu Xinliang Wang Xinmei Fan Jiulun 2010Journal of Electronics(China)2010,27,3:4
10Wideband adaptive microwave frequency identification using an integrated silicon photonic scanning filter显示文摘Photonic-assisted microwave frequency identification with distinct features, including wide frequency coverage and fast tunability, has been conceived as a key technique for applications such as cognitive radio and dynamic spectrum access. The implementations based on compact integrated photonic chips have exhibited distinct advantages in footprint miniaturization, light weight, and low power consumption, in stark contrast with discrete optical-fiber-based realization. However, reported chip-based instantaneous frequency measurements can only operate at a single-tone input, which stringently limits their practical applications that require wideband identification capability in modern RF and microwave applications. In this article, we demonstrate, for the first time, a wideband, adaptive microwave frequency identification solution based on a silicon photonic integrated chip,enabling the identification of different types of microwave signals from 1 to 30 GHz, including single-frequency,multiple-frequency, chirped-frequency, and frequency-hopping microwave signals, and even their combinations.The key component is a high Q-factor scanning filter based on a silicon microring resonator, which is used to implement frequency-to-time mapping. This demonstration opens the door to a monolithic silicon platform that makes possible a wideband, adaptive, and high-speed signal identification subsystem with a high resolution and a low size, weight, and power(SWaP) for mobile and avionic applications.XU WANG FENG ZHOU DINGSHAN GAO YANXIAN WEI XI XIAO SHAOHUA YU JIANJI DONG XINLIANG ZHANG 2019Photonics Research2019,7,2:3
11Broadband on-chip integrator based on silicon photonic phase-shifted Bragg grating显示文摘All-optical integrators are key devices for the realization of ultra-fast passive photonic networks, and, despite their broad applicability range(e.g., photonic bit counting, optical memory units, analogue computing, etc.), their realization in an integrated form is still a challenge. In this work, an all-optical integrator based on a silicon photonic phase-shifted Bragg grating is proposed and experimentally demonstrated, which shows a wide operation bandwidth of 750 GHz and integration time window of 9 ps. The integral operation for single pulse, inphase pulses, and π-shifted pulses with different delays has been successfully achieved.XU WANG FENG ZHOU SIQI YAN YUAN YU JIANJI DONG XINLIANG ZHANG 2017Photonics Research2017,5,3:3
12Role ofδ-ferrite in fatigue crack growth of AISI 316 austenitic stainless steel显示文摘FF sample(nearly free ofδ-ferrite)and CF sample(containing∼4%δ-ferrite)were prepared from the AISI 316 austenitic stainless steel plate to elucidate the role ofδ-ferrite in the fatigue crack growth under the solution treated and accelerated aged conditions.It is found that the fatigue crack growth resistance of the CF sample is higher than the FF sample under the solution treated condition.However,a significant deterioration of the fatigue crack growth resistance is observed in the CF sample while little variation is found in the FF sample after accelerated aging treatment at 750°C for 10 h.In the solution treated condition,deflected crack growth path is present when the main crack encounters theδ-ferrite in the CF sample due to the differences in the fatigue responses between austenite andδ-ferrite.The measured growth rate of the deflected crack is significantly slower than that of the flat crack of the same length.After the accelerated aging treatment,microcracks are produced at the M_(23)C_(6)/δinterface due to the strain incompatibility between M_(23)C_(6) and retainedδ-ferrite when the decomposedδ-ferrite is subject to plastic deformation in the crack tip plastic zone.The preexisting microcracks in the front of crack tip provide a viable path for crack propagation,resulting in the relatively flat crack path.Qiyu Wang Shenghu Chen Xinliang Lv Haichang Jiang Lijian Rong 2022Journal of Materials Science & Technology2022,,19:3
13Capturing dynamic biological signals via bio-mimicking hydrogel for precise remodeling of soft tissue显示文摘Soft tissue remodeling is a sophisticated process that sequentially provides dynamic biological signals to guide cell behavior.However,capturing these signals within hydrogel and directing over time has still been unrealized owing to the poor comprehension of physiological processes.Here,a bio-mimicking hydrogel is designed via thiol-ene click reaction to capture the early physical signal triggered by inflammation,and the chemical signals provided with chemokine and natural adhesion sites,which guaranteed the precise soft tissue remodeling.This bio-mimicking hydrogel efficiently facilitated cell anchoring,migration,and invasion in the 3D matrix due to the permissive space and the interaction with integrin receptors.Besides,the covalently grafted chemokine-like peptide is optimal for colonization and functional differentiation of endothelial cells through a HIF-1αdependent signal pathway.Furthermore,the early polarization of macrophages,collagen deposition and angiogenesis in rat acute wound model,and the increased blood perfusion in mouse skin flap model have confirmed that the bio-mimicking hydrogel realized precise soft tissue remodeling and opens new avenues for the phased repair of different tissues such as nerve,myocardium,and even bone.Zhengwei Cai Qimanguli Saiding Liang Cheng Liucheng Zhang Zhen Wang Fei Wang Xinliang Chen Gang Chen Lianfu Deng Wenguo Cui 2021Bioactive Materials2021,6,12:2
14Building durable aqueous K-ion capacitors based on MXene family显示文摘Obtaining stable aqueous K-ion capacitors is still challenging due to the cathode materials tended to structurally collapse after long-term cycling during large-radius K-ion insertion/extraction.In this work,three different typical MXene electrodes,i.e.,Nb_(2)C,Ti_(2)C,and Ti_(3)C_(2) were individually investigated upon their electrochemical behaviors for potassium-ion(K-ion)storage.All these MXene materials exhibited pseudocapacitive-dominated behaviors,fast kinetics,and durable K-ion storage,delivering superior performance compared with other K-ion host materials.According to the experimental results,it could be ascribed to the intrinsically large interlayer distance for K-ion transport and the superb structural stability of MXene even subjected to long-term potassiation/depotassiation process.Guojin Liang Xinliang Li Yanbo Wang Shuo Yang Zhaodong Huang Qi Yang Donghong Wang Binbin Dong Minshen Zhu Chunyi Zhi 2022Nano Research Energy2022,1,1:2

17In situ evidence of resonant interactions between energetic electrons and whistler waves in magnetopause reconnection显示文摘In this paper,we analyze one reconnection event observed by the Magnetospheric Multiscale(MMS)mission at the earth’s magnetopause.In this event,the spacecraft crossed the reconnection current sheet from the magnetospheric side to the magnetosheath side,and whistler waves were observed on both the magnetospheric and magnetosheath sides.On the magnetospheric side,the whistler waves propagated quasi-parallel to the magnetic field and toward the X-line,while on the magnetosheath side they propagated almost anti-parallel to the magnetic field and away from the X-line.Associated with the enhancement of the whistler waves,we find that the fluxes of energetic electrons are concentrated around the pitch angle 90°when their energies are higher than the minimum energy that is necessary for the resonant interactions between the energetic electrons and whistler waves.This observation provides in situ observational evidence of resonant interactions between energetic electrons and whistler waves in the magnetic reconnection.Zhi Li QuanMing Lu RongSheng Wang XinLiang Gao HuaYue Chen 2019Earth and Planetary Physics2019,3,6:2
18Autoantibody against angiotensin AT1 receptor from preeclamptic patients enhances collagen-induced human platelet aggregation显示文摘Hypercoagulability,血小板激活,和 thrombocytopenia 是 preeclampsia 的主要特征,但是他们的负责的内在的分子的机制仍然保持阴暗。最近的研究证明了对血管收缩素 II 类型 1 受体(AT1-AA ) 的自身抗体为 preeclampsia 组成一个新奇风险因素。然而,在血小板激活的 AT1-AA 和在 preeclampsia 的 hypercoagulability 的角色从来没被调查过。在现在的学习,我们决定了 AT1-AA 是否在 vitro 支持血小板聚集,并且把潜在的位于 \O 下面机制。AT1-AA 被连接酶的 immunosorbent 试金检测。在从 preeclamptic 病人净化的免疫球蛋白 G 部分以后,积极 sera 被加到从健康志愿者,血小板聚集和细胞内部的 Ca2+ 孤立的血小板层次被检测。AT1-AA 显著地在 vitro 提高了导致骨胶原的血小板聚集,效果由 AT1 受体对手 losartan 堵住了。另外, AT1-AA 在整个实验增加了并且维持导致骨胶原的 cytosolic 钙集中。我们第一次证明 AT1-AA 显著地在 vitro 通过血管收缩素类型 1 受体激活支持导致骨胶原的血小板聚集,潜在地经由增加的细胞内部的 Ca2+ 集中,作为一个潜在的贡献者支持 AT1-AA 到 preeclampsia 的 hypercoagulable 状态。Kehua Bai Ke Wang Xiaoyu Li Jie Wang Jie Zhang LiSong Jin Wang Suli Zhang Wayne Bond Lau Xinliang Ma Huirong Liu 2013Acta Biochimica et Biophysica Sinica2013,45,9:2

20Numerical simulation of the stress-strain curve and the stress and strain distributions of the titanium-duplex alloy显示文摘The stress-strain curve of an α-β Ti-8Mn alloy was measured and then it was calculated with finite element method (FEM) based on the stress-strain curves of the single α and β phase alloys. By comparing the calculated stress-strain curve with the measured one, it can be seen that they fit each other very well. Thus, the FE model built in this work is effective. According to the above mentioned model, the distributions of stress and strain in the α and β phases were simulated. The results show that the stress gradients exist in both α and β phases, and the distributions of stress are inhomogeneous. The stress inside the phase is generally higher than that near the interface. Meanwhile, the stress in the α phase is lower than that in the β phase, whereas the strain in the α phase is higher than that in the β phase.ZHAO Xiqinga ZANG Xinliang WANG Qingfeng Park Joongkeun YANG Qingxiang 2008Rare Metals2008,27,5:2
