We present a theoretical study of the medium modifications of the p_(T)balance (x_(J)) of dijets in Xe+Xe collisions at■.The initial production of dijets was carried out using the POWHEG+PYTHIA8 prescription,which matches the next-toleading-order (NLO) QCD matrix elements with the parton shower (PS) *** SHELL model described the in-medium evolution of nucleus–nucleus collisions using a transport *** theoretical results of the dijet xJin the Xe+Xe collisions exhibit more imbalanced distributions than those in the p+p collisions,consistent with recently reported ATLAS *** utilizing the Interleaved Flavor Neutralisation,an infrared-and-collinear-safe jet flavor algorithm,to identify the flavor of the reconstructed jets,we classify dijets processes into three categories:gluon–gluon (gg),quark–gluon (qg),and quark–quark (qq),and investigated the respective medium modification patterns and fraction changes of the gg,qg,and qq components of the dijet sample in Xe+Xe *** is shown that the increased fraction of qg component at a small x_(J)contributes to the imbalance of the dijet;in particular,the q_(1)g_(2)(quark-jet-leading) dijets experience more significant asymmetric energy loss than the g_(1)q_(2)(gluon-jet-leading) dijets traversing the *** comparing the■of inclusive,■ dijets in Xe+Xe collisions,we observe■.Moreover,ρ_(Xe),P_(b),the ratios of the nuclear modification factors of dijets in Xe+Xe to those in Pb+Pb,were calculated,which indicates that the yield suppression of dijets in Pb+Pb is more pronounced than that in Xe+Xe owing to the larger radius of the lead nucleus.

电商平台的强渗透性和广覆盖性,使电商经济变得异常火爆。但农产品在进入电商流量经济后,销售的产品逐渐模糊了自身价值,农产品电商价格逐渐偏离了实体市场农产品价格。农产品电商在推动农业科学种养、农村产业融合和农民增收等方面带来积极作用。通过探讨2022年农业农村部管理干部学院和阿里研究院联合公布的“农产品数字化百强县”典型县区的案例,对农产品电商优质优价给三农所带来的积极影响进行阐述。结合学者们对农产品定价、售价的影响因素进行分析,现阶段中国农产品电商“低价上行”现象较为普遍,且存在多平台竞争、谷贱伤农、无品牌经营等问题。为进一步推进农产品电商、农业电商“优质优价”发展,提出了推行分流机制、加强种养指导、关注产品细分、保护品牌等对策建议。
