Professor Zhang Jianghua

Published the latest research results in the direction of emergency logistics

Recently, Professor Zhang Jianghua's team made new progress in the direction of emergency logistics. The paper "Fuzzy-Control-Based CHANCED Programming for Humanitarian RELIEF ALLIECATION PROBLEM" was officially published in the international top of IEEEEEEEEEEEEEEEEEEEETRTARRANSAT). Professor Zhang Jianghua is the first author and communication author, Liu Yang, a doctoral student of the team, Professor Su Xiaojie of Chongqing University, and IEEE FELLOW Professor Peng Shi, Adelaide University.

The difficulty of accurate prediction of information such as uncertain demand and road driving time is one of the key factors that restrict the effectiveness of emergency resource deployment decision -making. Most of the existing research is based on the assumptions of the random point probability distribution. This is too ideal for emergencies, so the resource allocation scheme is low and the robustness is low under the condition of disturbance. The article innovatively adopts a fuzzy control method to introduce incomplete road information to the problem, and establish a mathematical model under unknown distribution situation to ensure the feasibility and robustness of the resource allocation scheme under disturbance. In order to improve the demand satisfaction rate in this situation, the article uses fuzzy theory to portray the uncertain needs under limited information. By opportunity constraint , Reliable path selection and emergency vehicle scheduling and other decisions. In response to the difficulties of blurring opportunities to restrain the planning and solution of excessive dimensions and parameter information fuzzy, the article builds a triangular fuzzy set and interval -based uncertain set, and proposes a new method of transforming fuzzy opportunities into a mixed integer model. Numerical experiments show that the blurring opportunity constraint model is more reliably reliability than the scenario -based random planning model, with lower total cost and the latest vehicle time to reach the time; sex.

Shanda Archaeological Team in France

Discover important ancient human fossils

Recently, the joint archeological team composed of Shandong University and Bordeaux University in France found two ancient human finger fossils in the excavation of the IrToiRAC Paleolithic Diuski era.

Under the leadership of Luneng, a foreign professor of Shandong University, the iconic fossils found from the archeological strata are exactly the same as the standards established by Oxford University, which can determine the age in the middle and late stages of Granit. The sequence of the previous age has been based on past excavations (1850-1950), which has made the place the key to studying the evolution of Gravit's cultural evolution before the last period of ice.

Naandrt's fingertips

Homo sapiens (suspected)

After the excavation team removed two boulder from the front of Yanxia, ​​it cleared the stolen and disturbed accumulation of the stolen destruction and re -organized the new stratigraphy profile. Although the landform is more complicated, many interesting materials have been found, such as the in the middle and late period of the Paleolithic Age (Moster and Granit), the tuberculosis of the mineral pigment, and the most interesting thing about the two human fingers, one of which is determined For the Neanderthal, the other may be the Homo sapiens.

Southern stratum section

It is not uncommon to find the cave ruins of the Neandertians and Homo sapiens at the same time in Europe and the Middle East. Human and Homes. The Pestera Cu Oase, which is about 35,000 years ago, shows the inlaid characteristics of the Naandrt and Homo sapiens. In recent years, the research of molecular biology has gradually revealed more and more Nian. Information about the Duters and Homo sapiens. Therefore, if more evidence of fossils coexisting with the Homo sapiens can be discovered in the place, then it is important for us to understand the cultural exchanges and genetic exchanges between the Naandart and Homo sapiens in the late life of the world. effect.

Undergraduate students of the School of Environment published a paper study and explore the metabolic activation and conversion mechanism of CYP1A1 catalyzed NF

Recently, Zhou Junhua and Zhang Xin of the School of Environmental Sciences and Engineering 2018 and Zhang Xin, the first author of the first author of environmental science and ecology, published on the ENVIRONMENT International (IF: 9.621) entitled "Endocrine-Disrupting Metabolic Activity of 2 -NITROFLUORENE CATALYZED by Human Cytochrome P450 1A1: A QM/MM Approach ". Shandong University is the only communication author unit. Zhou Junhua and Zhang Xin, a 2018 undergraduate student at the School of Environment, are the first authors. Associate Professor Li Yanwei of the Environment Research Institute is the communication author.

Nitro multi -ring aromatics (NPAHS) is one of the most important air pollutants. Recent research shows that as one of the richest NPAHS, 2-nitroe (NF) can be transformed into metabolites with endocrine interference by cytochrome P450 1A1 enzyme (CYP1A1) in human cells. However, related metabolic activation mechanisms still need to be explored to a large extent. In response to this problem, the study systematically explored the metabolic activation and transformation mechanism of CYP1A1 catalyzed NF through theoretical computing research methods such as molecular dynamics, density general letters, and quantum mechanics/molecular mechanics technology.

该研究证明CYP1A1可以通过两步基本过程来代谢活化NF：（i）亲电加成（12.4 kcal·mol-1）或氢提取（38.2 kcal·mol-1）过程和（ii）环氧化（ 5.9 and 8.7 kcal · mol-1) or NIH displacement (12.5 and 14.9 kcal · mol-1) or proton shuttle (12.1 kcal · mol-1) process. Studies have shown that the parenting bonus process is the speed determination step, and the epoxy process is a more feasible way after the parenting bonus. Metabolic products 6,7-epoxy-2-nitroe and 7,8-epoxy-2-nitro-2-nitrotida are identified as the main epoxy products. The epoxy is unstable, and it is easy to react with hydrogen-hydrogen ions and hydroxyl-based reactions to generate endocrine interference 7-hydroxyl-2-nitrate. Toxic analysis shows that some metabolites have greater toxicity to model aquatic creatures (such as green algae) than NF. Analysis of the combination of human hormone binding globulin shows that NF metabolites have endocrine interference potential. This study provides a comprehensive understanding of the NF biological conversion process and helps further study various NPAHS activation of human P450 enzyme catalysis.

Space Science Climbing Team in the Electric ionization layer in the polar region

New progress has been made in plasma cloud block research

Recently, the climbing team of Shandong University's "Sunburst and its impact on the planet space environment "-" Polar Area Electric ionization-Magnetic Layer Coupling "research team has made new progress in the research of plasma blocks in the polar region, and the results are" The research on the dependence of the local plasma transportation and particle sedimentation of local plasma blocks in winter cold/hot plasma cloud blocks in the northern hemisphere "was published on Geophysical Research Letters (GRL) (ZHANG DUAN, ET Al., 2022, JCR and Chinese Academy of Sciences. zone 1). Zhang Duan, a doctoral student of the research group, is the first author, the head of the project team Zhang Qinghe as the author of the paper, and Shandong University is the first and communication authors.

The polar ionizing layer plasma cloud block has always been one of the core research directions of the "ionization layer -magnetic layer coupling" research group, and has successively flickered the formation mechanism and evolution characteristics of plasma cloud blocks and its accompanying ionization and ionization layer. It has achieved a series of research results (published more than 15 SCI papers, including 1 SCIENCE, GRL 7, etc.). Recently, the research team also classified the sheets cloud block: cold and other ions cloud blocks (high density and low -electronic temperature) and hot plasma cloud blocks (high density and high electronic temperature), found that it has different space weather effects and effects and effects and effects and weather effects and effects and weather effects and weather effects and weather effects and weather effects and weather effects and weather effects and weather effects Different solar activity dependence, such as: The occurrence of cold and other ionic cloud blocks is obviously dependent on solar activity and geomagnetic activity, while thermal plasma cloud blocks are not as dependent; in the northern hemisphere winter, cold and hot plasma plasma body The spatial scale of the cloud block is reduced with the sun (geomagnetic) activity (zhang duan, et al., 2021). However, the dependence of cold/hot plasma cloud blocks on local plasma transportation and particle sedimentation has not been clear (the mystery of the cause).

Under the conditions of 8 different clock angles, the daytime-side cold plasma cloud block (blue) and thermal plasma cloud block (red) are distributed under the mloat-MLT coordinate system, and the ionizing layer statistics on the ionization layer ( Power potential, gray line), clock angle (θ = atan (by/bz)) is a interval every 45O, and the center clock angle of each interval is (A) -45o, (B) 0o, (C) 45o, etc. The yellow dotted line indicates pole ultraviolet light egg statistics to the boundary. The number of hot and cold clouds is marked in the upper right corner of each panel.

(A1-A4) The occurrence rate of plasma cloud blocks, (B1-B4) O+density, (C1-C4) electronic temperature (TE), (D1-D4) soft electrons (<1KEV) energy flux, and (E1-E1- E4) The Mlat of the Cross-track speed (Vcross-Track) is distributed from the clock angle. The two columns on the left correspond to the cold plasma cloud block, and the two rows on the right are cloud blocks corresponding to the thermal plasma. The data is divided into a grid with a 1MLAT and 10o clock angle. The black/ocean red thread in the panel A1-A4 identifies the MLAT connection corresponding to the maximum incidence of cloud blocks in the clock angle interval (the ocean red dotted line in the panel A1-A2 is overlapped with the panel A3-A4 ocean red solid line in order to change the more It is easy to compare the occurrence rate of hot and cold cloud blocks). Cold (blue)/hot (red) plasma cloud blocks and background conditions (gray) and horizontal flow speed (Vcross-Track) and soft electron settlement can be flushed. Blue and red dot lines represent the relative incidence of hot and cold cloud blocks, respectively. Panel A and B correspond to the south direction IMF, panel C and D correspond to north -direction IMF.

In this study, under the guidance of Professor Zhang Qinghe, Zhang Duan and other 4634 cold plasma cloud blocks (high density and low-electrical temperature) and 4700 thermal plasma were observed by the DMSP F16 satellite in the winter half-year in the winter of 2018. The cloud block (high density and high -electronic temperature) conducted statistical analysis, and studied the distribution and relative position of the ionizing layer in the polarized ionization plasma cloud block under different planetary magnetic fields (IMF) conditions. The dependence of cold/hot plasma cloud blocks on local plasma transportation and soft electron settlement. The results of the study show that in winter, (1) Cold/hot plasma cloud blocks are more distributed in the stronger ionization layer of the IMF modulation. (2) Cold -waiting cloud blocks are closer to the center of the pole cover area, while the thermal plasma cloud block is closer to the aurora eggs. (3) Under the conditions of BZ <0, the enhanced anti -sun flow (E x B drilling) promotes the generation of cold plasma clouds, and whether it is south or north of the planetary magnetic field or north, soft electronics promotes thermal plasma cloud block Express.

Invited to write comments in Nature Physics

Recently, the LHCB experiment at the European Nuclear Research Center announced the discovery of the new four quark particles TCC and studied its nature. At the same time, he published papers in Nature Physics and Nature Communications. Professor Liu Zhiqing of the Person Science and Technology Research Center of Shandong University Professor Liu Zhiqing, as an invitation expert of the Nature Physics journal, wrote a special review of news and viewpoints (News Views) on the title of "A Tetraquark Trophy".

Graval physics believes that strong seeds can be divided into three quarks and measons composed of positive and anti -quarks. Over the years, people have been trying to find a new strong sub -state beyond Chongzi and Jiezi to further understand the shape of the material and research strong interaction. Since the beginning of this century, many well -known large -scale cooperation teams in the world (Belle/Belle II, BABAR, LHCB, BESIII, etc. have all participated in more than 500 scientists) have invested a lot And found a series of evidence of the existence of new strong sub -state. Professor Liu Zhiqing has been active in BESIII and Belle/Belle II experiments for a long time to engage in the research of new strong sub -state. In 2013, the ZC (3900) particles discovered during the doctoral dissertation during the Besiii and Belle experiments were reported as the first four quark particles with exact experimental evidence, as shown in the figure above (a) above.

The TCC particles discovered by the LHCB experiment this time are the first four quark particles containing dual -oligraphy, with significant significance exceeding 22 times the standard deviation (particle physics experiments generally define more than 5 times the standard deviation), which may compose a possible quark composition As shown in the figure above (b). In addition, a interesting feature of TCC particles is at least 100 times that of its life expectancy. The discovery of the TCC particles has greatly expanded members of the physical family of Qiangzi, and prompts that there may be more unknown new strong children. At present, people's interpretation of the four quark particles mainly exists in the views of Genuine Tetraquark, Hadronic Molecule. As stated in the article comments, "No matter what kind of types of four quake particles are, these new particles represent a small number of people knowing a small number of people in the universe" "people's understanding of strong sub -material is far from complete" Essence

Reveal the impact of power trade on energy storage carbon emission reduction

近日，能源与动力工程学院袁学良教授团队在储能碳排放核算方面取得新进展，相关研究成果以“Estimation of Emission Factors from Purchased Electricity for European Countries: Impacts on Emission Reduction of Electricity Storage”为题发表在环境Domestic journal ENVIRONMENTAL Science Technology. The study was jointly completed by researchers from Shandong University and Liz University. Shandong University was the first completion unit of the paper. Tang Cosmic, a doctoral student of the School of Energy and Power Engineering, was the first author. Professor Yuan Xueliang was the only communication author of the paper.

In order to evaluate the carbon emission reduction effect brought by energy storage technology, we must first master the accurate data of electricity production of carbon emissions. When evaluating the marginal emissions factor (MEFS) to calculate power carbon emissions, due to the lack of large -scale large -scale power data for high -resolution of European countries, the existing MEF computing is mainly based on power generation emissions and direct power transmission emissions. However, the hidden emissions flow in the power trading network will bring a significant deviation to carbon emissions accounting and have a significant impact on the carbon emission calculation of the energy storage system. In view of this, Professor Yuan Xueliang's team used the power generation data and power trade data of 28 countries in Europe to comprehensively examine the impact of power trade on carbon accounting and MEF computing, and constructed three energy storage scenarios to evaluate carbon that used power storage countries Reduction potential.

Figure 128 of the power generation structure of European countries

Figure 2 28 Electricity and carbon emissions transfer between 28 European countries

Researchers specifically evaluated the impact of power trade on electricity carbon emissions. The results show that if the impact of power transactions is not considered, the errors of carbon emission accounting and MEF computing are 7%and 10%, indicating that power transactions have an important impact on the accuracy of power consumption MEF; The error of emissions accounting and MEF calculation is 1%, and it is contrary to the impact trend of power transactions. Therefore, only considering the impact of direct power transfer to overly evaluate the carbon emissions transfer of power trade.

Figure 3 Evaluation of carbon reduction displacement with different energy storage efficiency

Researchers evaluated the emission reduction effect of European countries to implement different storage operation scenarios. The results show that the accuracy of MEF computing has a considerable impact on the result of emission reduction, and generally underestimates the revenue reduction income obtained by these countries in the reduction of the scene. Energy storage cycle efficiency greatly affects the carbon emission reduction effect of energy storage technology. When the storage efficiency in the peak scene is less than 70% and 90% of the wind -energy balance scene, all countries will increase power carbon emissions. In reducing the abandonment of electricity, no matter how the storage cycle efficiency decreases, storage operations can always obtain emission reduction income in all countries. With the efficiency of only 50%, the scheme can achieve emission reduction benefits of more than 100G CO2/KWH. The work is based on the carbon nuclear calculation results within three range, which can provide a reference for accurately calculating MEF. Study the effects of MEF's accuracy on the effect of carbon reduction and emission reduction effect on energy storage, and provides countermeasure suggestions from the perspective of policy and management.
