| 1 | Optimal Energy Flow and Nodal Energy Pricing in Carbon Emission-embedded Integrated Energy Systems显示文摘Green energy is driving the evolutions of energy industry and carbon emission is becoming an important concern.Considering the increasing couplings among various energy sectors,this paper investigates multi-period optimal energy flow and energy pricing in carbon-emission embedded integrated energy systems,including electricity,natural gas,and district heating networks.Firstly,an optimal scheduling model of integrated energy systems was proposed in this paper.The models of DC power flow,natural gas pipeline flow and heating network energy flow are presented and linearized for the optimization problem.Natural gas-fired generators and combined heat and power(CHP)units are modeled as coupling components of electricitygas and electricity-heating networks.Then,based on the optimal scheduling model,the locational marginal prices(LMP)for electricity,natural gas and heating network are determined.Moreover,the carbon emission caused by energy production has been taken into account in the optimal scheduling and energy pricing process.Finally,case studies on a combined network consisting of IEEE 39-bus system,Belgium 20-node natural gas system and 6-node heating system demonstrate the effectiveness of the proposed model and the impacts of carbon emission on system scheduling and LMP. | Tao Jiang Hongwei Deng Linquan Bai Rufeng Zhang Xue Li Houhe Chen | 2018 | CSEE Journal of Power and Energy Systems2018，4，2： | 13 |
| 2 | Day-ahead Scheduling of Multi-carrier Energy Systems with Multi-type Energy Storages and Wind Power显示文摘The integration of large-scale wind power brings challenges to the operation of integrated energy systems(IES).In this paper,a day-ahead scheduling model for IES with wind power and multi-type energy storage is proposed in a scenario-based stochastic programming framework.The structure of the IES consists of electricity,natural gas,and heating networks which are all included in the model.Operational constraints for IES incorporating multi-type energy storage devices are also considered.The constraints of the electricity network,natural gas network and heating network are formulated,and non-linear constraints are linearized.The calculation method for the correlation of wind speed between wind farms based on historical data is proposed.Uncertainties of correlated wind power were represented by creating multiple representative scenarios with different probabilities,and this was done using the Latin hyper-cube sampling(LHS)method.The stochastic scheduling model is formulated as a mixed integer linear programming(MILP)problem with the objective function of minimizing the total expected operation cost.Numerical results on a modified PJM 5-bus electricity system with a seven-node natural gas system and a six-node heating system validate the proposed model.The results demonstrate that multi-type energy storage devices can help reduce wind power curtailments and improve the operational flexibility of IES. | Rufeng Zhang Tao Jiang Guoging Li Houhe Chen Xue Li Linquan Bai Hantao Cui | 2018 | CSEE Journal of Power and Energy Systems2018，4，3： | 13 |
| 3 | Vitality and wound-age estimation in forensic pathology:review and future prospects显示文摘Determining the age of a wound is challenging in forensic pathology,but it can contribute to the reconstruction of crime scenes and lead to arrest of suspects.Forensic scholars have tended to focus on evaluating wound vitality and determining the time elapsed since the wound was sustained.Recent progress in forensic techniques,particularly high-throughput analyses,has enabled evaluation of materials at the cellular and molecular levels,as well as simultaneous assessment of multiple markers.This paper provides an update on wound-age estimation in forensic pathology,summarizes the recent literature,and considers useful additional informa-tion provided by each marker.Finally,the future prospects for estimating wound age in foren-sic practise are discussed with the hope of providing something useful for further study. | Na Li Qiuxiang Du Rufeng Bai Junhong Sun | 2020 | Forensic Sciences Research2020，5，1： | 5 |
| 4 | M2-specific reduction of CD1d switches NKT cell-mediated immune responses and triggers metaflammation in adipose tissue显示文摘Metaflammation is responsible for several metabolic syndromes,such as type 2 diabetes.However,the mechanisms by which metabolic disorders trigger metaflammation remain unclear.We identified a cell type-specific downregulation of CD1d expression in M2 macrophages during the progression of obesity prior to the onset of inflammation in visceral adipose tissues.A reduction in CD1d expression influenced the ability of M2 macrophages to present antigens and caused a change in antigen-presenting cells from M2 macrophages to M1 macrophages.With CD1d conditional knockout(KO)mice,we further demonstrated that natural killer T(NKT)cell activation by M2 macrophages inhibited metaflammation and insulin resistance by promoting Th2 responses and M2 polarization in visceral adipose tissues of obese mice,whereas NKT cell activation by M1 macrophages exacerbated metaflammation and insulin resistance by promoting Th1 responses and inhibiting M2 polarization.Our results suggest that an M2-specific reduction of CD1d is an initiating event that switches NKT cell-mediated immune responses and disrupts the immune balance in visceral adipose tissues in obese mice. | Huimin Zhang Rufeng Xue Shasha Zhu Sicheng Fu Zuolong Chen Rongbin Zhou Zhigang Tian Li Bai | 2018 | Cellular & Molecular Immunology2018，15，5： | 3 |
| 5 | Analysis of sensitivity and specificity:precise recognition of neutrophils during regeneration of contused skeletal muscle in rats显示文摘In this report,we applied the TissueFAXS 200 digital pathological analysis system to rapidly and accurately identify neutrophils during regeneration of contused skeletal muscle,and to provide information for follow-up studies on neutrophils to estimate wound age.Rat injury model was established,and skeletal muscle samples were obtained from the control group and contusion groups at 1,1.5,2,3,4,and 6 h,as well as at 1,3,5,and 15 d post-injury(n紏5 per group).The expression of nuclei and neutrophils was detected by hematoxylin and eosin(HE)staining and immunohistochemical(IHC)staining.A total of 20 injury site areas of 0.25mm^(2)(0.5mm0.5mm)were then randomly selected at all time points.A TissueFAXS 200 digital pathological analysis system was used to identify the positive and negative numbers.Knowledge of five professional medical workers were considered the gold standard to measure the false positive rate(FPR),false negative rate(FNR),sensitivity,specificity,and area under the curve(AUC)of receiver operating characteristic(ROC)curves.As a result,with a staining area of neutrophils from 8 μm^(2) to 15 μm^(2),the FPR was 4.28%–12.14%,the FNR was 12.42%–64.08%,the sensitivity was 35.92%–87.58%,the specificity was 87.86%–95.72%,the Youden index was 0.316–0.754,the accuracy was 82.80%–88.30%,and the AUC was 0.771–0.826.The AUC was largest when the cut-off value of the staining area was 12 mm^(2).Our results show that this software-based method is more accurate than the human eye in evaluating neutrophil infiltration.Based on the sensitivity and specificity,neutrophils can be accurately identified during regeneration of contused skeletal muscle.The TissueFAXS 200 digital pathological analysis system can also be used to optimize conditions for different cell types under various injury conditions to determine the optimal cut-off value of the staining area and provide optimal conditions for further study.Furthermore,it will provide evidence for forensic pathology cases. | Jiajia Niu Guoshuai An Zhen Gu Peng Li Qiqing Liu Rufeng Bai Junhong Sun Qiuxiang Du | 2022 | Forensic Sciences Research2022，7，2： | 2 |

| 9 | Estimation of the Postmortem Interval by Measuring Blood Oxidation‑reduction Potential Values显示文摘Accurate estimation of the postmortem interval(PMI)is an important task in forensic practice.In the last half-century,the use of postmortem biochemistry has become an important ancillary method in determining the time of death.The present study was carried out to determine the correlation between blood oxidation-reduction potential(ORP)values and PMIs,and to develop a three-dimensional surface equation to estimate the PMI under various temperature conditions.A total of 48 rabbits were placed into six groups and sacrificed by air embolism.Blood was obtained from the right ventricle of each rabbit,and specimens were stored at 10℃,15℃,20℃,25℃,30℃,and 35℃.At different PMIs(once every 4 h),the blood ORP values were measured using a PB-21 electrochemical analyzer.Statistical analysis and curve fitting of the data yielded cubic polynomial regression equations and a surface equation at different temperatures.Result:The results showed that there was a strong positive correlation between the blood ORP values at different temperatures and the PMI.This study provides another example of using a three-dimensional surface equation as a tool to estimate the PMI at various temperature conditions. | Zhuqing Jiang Meng You Xu Wang Di Lu Haidong Zhang Shengli Di Fengqin Zhang Zhaoming Guo Xiaofei E Lin Chang Jian Xiang Rufeng Bai Tiantong Yang | 2016 | Journal of Forensic Science and Medicine2016，2，1： | 0 |
| 10 | Primary Screening for Proteins Differentially Expressed in the Myocardium of a Rat Model of Acute Methamphetamine Intoxication显示文摘The mechanism of myocardial injury induced by the cardiovascular toxicity of methamphetamine(MA)has been shown to depend onalterations in myocardial proteins caused by MA.Primary screening of the expression of myocardial proteins in a rat model of MA intoxicationwas achieved by combining two‑dimensional electrophoresis and mass spectrometry analyses,which revealed a total of 100 differentiallyexpressed proteins.Of these,13 displayed significantly altered expression.Moreover,Western blotting and real‑time reverse transcriptionquantitative polymerase chain reaction analyses of several relative proteins demonstrated that acute MA intoxication lowers protein expressionand mRNA transcription of aldehyde dehydrogenase‑2 and NADH dehydrogenase(ubiquinone)1 alpha subcomplex subunit 10.In contrast,MA intoxication elevated the protein expression and mRNA transcription of heat shock protein family B(small)member 1.By combiningbehavioral assessments of experimental rat models with the histological and pathological changes evident in cardiomyocytes,a mechanismaccounting for MA myocardial toxicity was suggested.MA alters the regulation of gene transcription and the subsequent expression of certainproteins that participate in myocardial respiration and in responding to oxidative stress,resulting in myocardial dysfunction and structuralchanges that affect the functioning of the cardiovascular system. | Guoqiang Qu Sizhe Huang Liang Liu Tianshui Yu Rufeng Bai Hongxia Liu Fangming Song Yongqi Wen Haidong Zhang | 2016 | Journal of Forensic Science and Medicine2016，2，3： | 0 |
| 11 | Use of Different Murder Weapons by a Single Murderer:Two Case Reports显示文摘Homicide is an extremely serious crime,and although the offender usually uses the same weapon to initially injure and complete the killing,there are exceptions.We report two cases in which a single murderer killed a victim using different weapons and summarize several situations in which a murderer might use different weapons to kill.The number of murders should be determined and estimated after a comprehensive complicated investigation of the scene,careful examination of the victim’s injuries,and evaluation of evidence reported by eyewitnesses. | Eradil Orazhkan Tao Pu Longlong Wang Zhimin Wang Zhiwei Zhu Rufeng Bai | 2016 | Journal of Forensic Science and Medicine2016，2，3： | 0 |
