| 1 | Low-carbon unit commitment with intensive wind power generation and carbon capture power plant显示文摘The paper proposes a stochastic unit commitment(UC)model to realize the low-carbon operation requirement and cope with wind power prediction errors for power systems with intensive wind power and carbon capture power plant(CCPP).A linear re-dispatch strategy is introduced to compensate the wind power deviation from the spot forecast.The robust optimization technique is employed to obtain a reliable commitment plan against all realizations of wind power within the uncertainty set given by probabilistic forecast.The proposed model is validated with IEEE 39-bus system.The advantages of flexible CCPPs are compared to the normal coal-fueled plants and the impacts of robustness controlling are discussed. | Jiaming LI Jinyu WEN Xingning HAN | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，1： | 19 |
| 2 | Transmission Network Expansion Planning Considering Uncertainties in Loads and Renewable Energy Resources显示文摘This paper proposes a novel method for transmission network expansion planning(TNEP)that take into account uncertainties in loads and renewable energy resources.The goal of TNEP is to minimize the expansion cost of candidate lines without any load curtailment.A robust linear optimization algorithm is adopted to minimize the load curtailment with uncertainties considered under feasible expansion costs.Hence,the optimal planning scheme obtained through an iterative process would be to serve loads and provide a sufficient margin for renewable energy integration.In this paper,two uncertainty budget parameters are introduced in the optimization process to limit the considered variation ranges for both the load and the renewable generation.Simulation results obtained from two test systems indicate that the uncertainty budget parameters used to describe uncertainties are essential to arrive at a compromise for the robustness and optimality,and hence,offer a range of preferences to power system planners and decision makers. | Jinyu Wen Xingning Han Jiaming Li Yan Chen Haiqiong Yi Chang Lu | 2015 | CSEE Journal of Power and Energy Systems2015，1，1： | 17 |

| 5 | Mesenteric lymph reperfusion may exacerbate brain injury in a rat model of superior mesenteric artery occlusion shock显示文摘BACKGROUND:The intestinal lymphatic pathway and intestinal ischemia/reperfusion are mainly involved in mesenteric lymph duct ligation or drainage;moreover,intervention by reducing the lymph liquid reflux might relieve lung and other organ dysfunction induced by intestinal ischemia/reperfusion;however,research addressing mesenteric lymph reperfusion (MLR) and brain injury has not yet to be reported.OBJECTIVE:To observe the effect of MLR on brain tissue in a rat model of superior mesenteric artery occlusion (SMAO) shock,and to explore the molecular mechanism of MLR.DESIGN,TIME AND SETTING:A randomized,controlled,animal experiment at a neuro-pathophysiology level was performed at the Institute of Microcirculation,Hebei North University;Department of Pathophysiology,Basic Medical College;Department of Pathology,the First Hospital of Hebei North University between December 2007 and March 2009.MATERIALS:Adenosine triphosphate (ATP) standard was provided by the National Institute for the Control of Pharmaceutical and Biological Products;lactic acid (LA),superoxide dismutase (SOD),malonaldehyde (MDA),nitrogen monoxidum (NO),nitric oxide synthase (NOS),myeloperoxidase (MPO) and ATPase assay kits were provided by Nanjing Jiancheng Bioengineering Institute,China.METHODS:A total of 24 male Wistar rats were randomly divided into four groups.In the sham-surgery group (n=6),both the mesenteric lymph duct and the superior mesenteric artery were not blocked;in the MLR group (n=6),the mesenteric lymph duct was occluded for 1 hour followed by 2-hour reperfusion;in the SMAO group (n=6),the superior mesenteric artery was occluded for 1 hour followed by 2-hour reperfusion;in the MLR + SMAO group (n=6),both the mesenteric lymph duct and superior mesenteric artery were occluded for 1 hour followed by 2-hour reperfusion.MAIN OUTCOME MEASURES:Mean arterial blood pressure prior to and following ischemia/reperfusion;brain tissue morphology levels of LA,MDA,SOD,NO,NOS,MPO,ATPase and ATP following reperfusion.RESULTS:MLR did not cause changes in mean arterial blood pressure,brain tissue morphology,LA,MDA,NO,ATP,SOD,NOS,MPO and ATPase.However,SMAO caused a rapid decrease and gradual increase of mean arterial blood pressure.Neuronal necrosis,degeneration and swelling were observed in brain tissue.Contents of MDA,NO,LA and ATP as well as activities of NOS and MPO were significantly increased (P < 0.05),but activities of SOD and Na+-K+-ATPase were significantly decreased (P < 0.05).MLR aggravated neuronal damage in a rat model of SMAO shock.Following MLR,mean arterial blood pressure was significantly decreased (P < 0.05),contents of MDA and NO as well as activities of NOS and MPO were significantly increased (P < 0.05),but activities of Ca2+-ATPase,Mg2+-ATPase and Ca2+-Mg2+-ATPase as well as ATP content were significantly decreased (P < 0.05).CONCLUSION:MLR aggravates brain injury in a rat model of SMAO shock,which correlates with oxygen-derived free radical injury,NO synthesis and release,sequestration of neutrophilic granulocytes,decreasing activity of cell membrane pumps and energy metabolism dysfunction.Pathogenesis of the intestinal lymphatic pathway should be thoroughly investigated to prevent ischemia/reperfusion injury. | Zigang Zhao Chunyu Niu Aimin Shang Jiaming Tian Rui Han Chunhui Zhang Yuping Zhang Jing Zhang | 2010 | Neural Regeneration Research2010，5，9： | 7 |
| 6 | Understanding of mineral change mechanisms in coal mine groundwater reservoir and their influences on effluent water quality:a experimental study显示文摘This paper presents results of an experimental study to characterize the law of mineral change of fallen rock in coal mine groundwater reservoir ant its influence on water quality.The minerals of the underground reservoir of Daliuta Coal Mine is taken as the research object.Simulation experiments were designed and conducted to simulate water–rock action in the laboratory.The mineral composition was analyzed by X-ray diffractometer(XRD),the surface morphology of the mineral was analyzed by scanning electron microscope(SEM),and the specific surface area,total pore volume and average pore diameter of the mineral were measured by fast specific surface/pore analyzer(BET).The experimental results show that the sandstone and mudstone in the groundwater reservoir of Daliuta Coal Mine account for 70%and 30%,respectively.The pore diameter is 15.62–17.55 nm,and pore volume is 0.035 cc/g.Its pore structure is a key factor in the occurrence of water–rock interaction.According to the water–rock simulation experiment,the quartz content before the water–rock action is about 34.28%,the albite is about 21.84%,the feldspar is about 17.48%,and the kaolinite is about 8.00%.After the water–rock action,they are 36.14%,17.78%,11.62%,and 16.75%,respectively.The content of albite and orthoclase is reduced while the content of kaolinite is increased,that is,the Na+content becomes higher,and the Ca2+and Mg2+contents become lower.This research builds a good theoretical foundation for revealing the role of water and rock in underground coal reservoirs. | Kai Zhang Huifang Li Jiaming Han Binbin Jiang Ju Gao | 2021 | International Journal of Coal Science & Technology2021，8，1： | 3 |
| 7 | Reduced graphene oxide aerogel decorated with Mo_(2)C nanoparticles toward multifunctional properties of hydrophobicity,thermal insulation and microwave absorption显示文摘Reduced graphene oxide(rGO)aerogels are emerging as very attractive scaffolds for high-performance electromagnetic wave absorption materials(EWAMs)due to their intrinsic conductive networks and intricate interior microstructure,as well as good compatibility with other electromagnetic(EM)components.Herein,we realized the decoration of rGO aerogel with Mo_(2)C nanoparticles by sequential hydrothermal assembly,freeze-drying,and high-temperature pyrolysis.Results show that Mo_(2)C nanoparticle loading can be easily controlled by the ammonium molybdate to glucose molar ratio.The hydrophobicity and thermal insulation of the rGO aerogel are effectively improved upon the introduction of Mo_(2)C nanoparticles,and more importantly,these nanoparticles regulate the EM properties of the rGO aerogel to a large extent.Although more Mo_(2)C nanoparticles may decrease the overall attenuation ability of the rGO aerogel,they bring much better impedance matching.At a molar ratio of 1:1,a desirable balance between attenuation ability and impedance matching is observed.In this context,the Mo_(2)C/r GO aerogel displays strong reflection loss and broad response bandwidth,even with a small applied thickness(1.7 mm)and low filler loading(9.0wt%).The positive effects of Mo_(2)C nanoparticles on multifunctional properties may render Mo_(2)C/r GO aerogels promising candidates for high-performance EWAMs under harsh conditions. | Yahui Wang Minghui Zhang Xuesong Deng Zhigang Li Zongsheng Chen Jiaming Shi Xijiang Han Yunchen Du | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，3： | 2 |
| 8 | A wave propagation model with the Biot and the fractional viscoelastic mechanisms显示文摘Energy loss in porous media containing fluids is typically caused by a variety of dynamic mechanisms.In the Biot theory,energy loss only includes the frictional dissipation between the solid phase and the fluid phase,resulting in underestimation of the dispersion and attenuation of the waves in the low frequency range.To develop a dynamic model that can predict the high dispersion and strong attenuation of waves at the seismic band,we introduce viscoelasticity into the Biot model and use fractional derivatives to describe the viscoelastic mechanism,and finally propose a new wave propagation model.Unlike the Biot model,the proposed model includes the intrinsic dissipation of the solid frame.We investigate the effects of the fractional order parameters on the dispersion and attenuation of the P-and S-waves using several numerical experiments.Furthermore,we use several groups of experimental data from different fluid-saturated rocks to testify the validity of the new model.The results demonstrate that the new model provides more accurate predictions of high dispersion and strong attenuation of different waves in the low frequency range. | Jiaming YANG Dinghui YANG Hongwei HAN Lingyun QIU Yuanfeng CHENG | 2021 | Science China Earth Sciences2021，64，3： | 2 |
| 9 | Influence of mesenteric lymph reperfusion on neurotransmitter expression in brain tissue of a superior mesenteric artery occlusion shock rat model显示文摘BACKGROUND: Previous studies have shown that mesenteric lymph reperfusion (MLR) exacerbates brain injury in a rat model of superior mesenteric artery occlusion (SMAO) shock. However, little is known about the influence of MLR on neurotransmitter expression in brain tissue. OBJECTIVE: To observe the effect of MLR on brain tissue injury by measuring monoamine and cholinergic neurotransmitter levels. DESIGN, TIME AND SETTING: A randomized, controlled, animal experiment was performed at the Institute of Microcirculation, Hebei North University, China; Research Room of Microcirculation and Laboratory of Biochemistry, Department of Pathophysiology, Basic Medical College, Hebei North University between December 2007 and March 2009. MATERIALS: Choline acetyltransferase (ChAT) and acetylcholine esterase (AChE) kits were provided by Nanjing Jiancheng Bioengineering Institute, China; dopamine (DA) and noradrenalin (NE) standards were provided by the National Institute for the Control of Pharmaceutical and Biological Products; HP1100 chromatograph of liquid was provided by Agilent, USA. METHODS: A total of 24 male, Wistar rats were randomly assigned to 4 groups: sham-surgery, MLR, SMAO, and MLR + SMAO groups, with 6 rats in each group. In the MLR or SMAO groups, the mesenteric lymph duct or superior mesenteric artery was blocked for 1 hour. In the MLR + SMAO group, the mesenteric lymph duct and superior mesenteric artery were occluded for 1 hour, followed by 2-hour reperfusion. ChAT and AChE levels were measured using the synthesized and hydrolyzed acetylcholine method, respectively. Liquid chromatography was employed to quantitatively analyze DA and NE levels, using relative retention time and the external standard method. MAIN OUTCOME MEASURES: ChAT, AChE, DA, and NE levels. RESULTS: AChE levels were significantly increased, but ChAT levels were significantly decreased in the MLR and MLR + SMAO groups following 2-hour reperfusion (P < 0.01). However, AChE activity in the MLR + SMAO group was greater than in the MLR group (P < 0.05). DA and NE levels were significantly decreased in the SMAO and MLR + SMAO groups (P < 0.01), while DA levels in the MLR + SMAO group were less than in the SMAO group (P < 0.05). CONCLUSION: MLR exacerbated brain injury in a rat model of SMAO shock, which correlated with the intestinal lymphatic pathway. MLR decreased DA levels, but increased AChE activity, in a rat model of SMAO shock. | Chunyu Niu Zigang Zhao Aimin Shang Jiaming Tian Chunhui Zhang Rui Han Yuping Zhang Jing Zhang | 2010 | Neural Regeneration Research2010，5，11： | 2 |

| 13 | An Elliptic Centerness for Object Instance Segmentation in Aerial Images显示文摘Instance segmentation in aerial images is an important and challenging task.Most of the existing methods have adapted instance segmentation algorithms developed for natural images to aerial images.However,these methods easily suffer from performance degradation in aerial images,due to the scale variations,large aspect ratios,and arbitrary orientations of instances caused by the bird’s-eye view of aerial images.To address this issue,we propose an elliptic centerness(EC)for instance segmentation in aerial images,which can assign the proper centerness values to the intricate aerial instances and thus mitigate the performance degradation.Specifically,we introduce ellipses to fit the various contours of aerial instances and measure these fitted ellipses by two-dimensional anisotropic Gaussian distribution.Armed with EC,we develop a one-stage aerial instance segmentation network.Extensive experiments on a commonly used dataset,the instance segmentation in aerial images dataset(iSAID),demonstrate that our proposed method can achieve a remarkable performance of instance segmentation while introducing negligible computational cost. | Yixin Luo Jiaming Han Zhou Liu Mi Wang Gui-Song Xia | 2022 | Journal of Remote Sensing2022，，1： | 0 |
| 14 | A facile solution phase synthesis of directly ordering monodisperse FePt nanoparticles显示文摘The ordered Pt-based intermetallic nanoparticles(NPs)with small size show superior magnetic or catalytic properties,but the synthesis of these NPs still remains a great challenge due to the requirement of high temperature annealing for the formation of the ordered phase,which usually leads to sintering of the NPs.Here,we report a simple approach to directly synthesize monodisperse ordered L1_(0)-FePt NPs with average size 10.7 nm without further annealing or doping the third metal atoms,in which hexadecyltrimethylammonium chloride(CTAC)was found to be the key inducing agent for the thermodynamic growth of the Fe and Pt atoms into the ordered intermetallic structure in the synthetic process.In particular,10.7 nm L1_(0)-FePt NPs synthesized by the proper amount of CTAC show a coercivity of 3.15 kOe and saturation magnetization of 45 emu/g at room temperature.The current CTAC-assisted synthetic strategy makes it possible to deeply understand the formation of the ordered Pt-based intermetallic NP in solution phase synthesis. | Yongsheng Yu Lin He Junjie Xu Jiaming Li Sida Jiang Guanghui Han Baojiang Jiang Wenjuan Lei Weiwei Yang Yanglong Hou | 2022 | Nano Research2022，15，1： | 0 |

| 16 | Highly Efficient Aligned Ion‑Conducting Network and Interface Chemistries for Depolarized All‑Solid‑State Lithium Metal Batteries显示文摘Improving the long-term cycling stability and energy density of all-solid-state lithium(Li)-metal batteries(ASSLMBs)at room temperature is a severe challenge because of the notorious solid–solid interfacial contact loss and sluggish ion transport.Solid electrolytes are generally studied as two-dimensional(2D)structures with planar interfaces,showing limited interfacial contact and further resulting in unstable Li/electrolyte and cathode/electrolyte interfaces.Herein,three-dimensional(3D)architecturally designed composite solid electrolytes are developed with independently controlled structural factors using 3D printing processing and post-curing treatment.Multiple-type electrolyte films with vertical-aligned micro-pillar(p-3DSE)and spiral(s-3DSE)structures are rationally designed and developed,which can be employed for both Li metal anode and cathode in terms of accelerating the Li+transport within electrodes and reinforcing the interfacial adhesion.The printed p-3DSE delivers robust long-term cycle life of up to 2600 cycles and a high critical current density of 1.92 mA cm^(−2).The optimized electrolyte structure could lead to ASSLMBs with a superior full-cell areal capacity of 2.75 mAh cm^(−2)(LFP)and 3.92 mAh cm^(−2)(NCM811).This unique design provides enhancements for both anode and cathode electrodes,thereby alleviating interfacial degradation induced by dendrite growth and contact loss.The approach in this study opens a new design strategy for advanced composite solid polymer electrolytes in ASSLMBs operating under high rates/capacities and room temperature. | Yongbiao Mu Shixiang Yu Yuzhu Chen Youqi Chu Buke Wu Qing Zhang Binbin Guo Lingfeng Zou Ruijie Zhang Fenghua Yu Meisheng Han Meng Lin Jinglei Yang Jiaming Bai Lin Zeng | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 17 | Consistency correction of echo intensity data for multiple radar systems and its application in quantitative estimation of typhoon precipitation显示文摘Calibration error is one of the primary sources of bias in echo intensity measurements by ground-based radar systems.Calibration errors cause data discontinuity between adjacent radars and reduce the effectiveness of the radar system.The Global Precipitation Measurement Kuband Precipitation Radar(GPM KuPR)has been shown to provide stable long-term observations.In this study,GPM KuPR observations were converted to S-band approximations,which were then matched spatially and temporally with ground-based radar observations.The measurements of stratiform precipitation below the melting layer collected by the KuPR during Typhoon Ampil were compared with those of multiple radar systems in the Yangtze River Delta to determine the deviations in the echo intensity between the KuPR and the ground-based radar systems.The echo intensity data collected by the ground-based radar systems was corrected using the KuPR observations as reference,and the correction results were verified by comparing them with rain gauge observations.It was found that after the correction,the consistency of the echo intensity measurements of the multiple radar systems improved significantly,and the precipitation estimates based on the revised ground-based radar observations were closer to the rain gauge measurements. | Shuai ZHANG Jing HAN Bingke ZHAO Zhigang CHU Jie TANG Limin LIN Xiaoqin LU Jiaming YAN | 2022 | Frontiers of Earth Science2022，16，1： | 0 |
| 18 | Nutritional value of domesticated duckweed variety DW2602 and its feeding effects on the growth performance and digestive activities of tilapia fingerlings显示文摘Duckweed are a family of fast-growing aquatic plants,in which wild plants of many species have been tested in animal feed.We domesticated a duckweed variety,Spirodela polyrhiza DW2602,which had 44.5%protein and 2.6% lysine and was grown on a large scale.The effects of DW2602 on the growth performance and the digestive enzyme activities of tilapia variety GIFT(Genetic Improvement of Farmed Tilapia,Oreochromis niloticus)fingerlings were evaluated.The dry powder of DW2602 was added to conventional tilapia feed at six inclusion levels of 0%,10%,15%,20%,25%,and 30%.The diets were fed to tilapia fingerlings with an initial weight of 2.0±0.15 g for 60 d.Results showed that DW2602 improved the growth performance and digestive enzyme activities significantly.The feeding effect was the best when the inclusion rate was 20%,in which the body weight increased to 37.24±1.21 g in 60 d,18.15%higher than the control(P<0.05).The weight gain rate,the specific growth rate,the condition factor,and the hepatosomatic index of the fish were all significantly higher than the control(P<0.05),and the amylase,protease,and lipase activities in the digestive system were all promoted by DW2602(P<0.05).Therefore,the duckweed variety DW2602 has great application prospect in tilapia culture. | Bingying Han Ting Chen Bohan Yu Yuepan Ren Yuhan Long Deguan Tan Lili Fu Jiaming Zhang | 2022 | Tropical Plants2022，1，1： | 0 |
