Within the framework of nonrelativistic-QCD factorization,we calculate both the next-to-leading-order relativistic and QCD corrections to prompt J/ψpair production,with feed-down fromψ(2S)mesons,via photon-photon collisions at future e^(+)e^(−)colliders,including the Future Circular Lepton Collider(FCC-ee),the Circular Electron Positron Collider(CEPC),and the Compact Linear Collider(CLIC).We present total cross sections and distributions in single J/ψtransverse momentum and rapidity,as well as in J/ψpair invariant *** relativistic and QCD corrections both turn out to be large and ***,the production rates are large enough for useful experimental studies.

垂直腔面发射激光器（VCSEL）与并行光传输、光互连等领域的数据传输需求相契合，能够应用于单通道和并行光互联网络，是宽带以太网、高速数据通信中关键的光电子器件。而热效应严重限制了VCSEL的带宽等高速调制性能并影响输出的稳定性，通过优化电流分布、调整氧化孔径、减薄衬底、使用高热导率的材料、键合热沉等方式有助于VCSEL的热耗散。本文综述了VCSEL热管理等方面的研究进展，这对于提升其高速调制性能至关重要，最后介绍了本课题组最新设计的具有高效散热结构的高速多孔孔径VCSEL。

In a recent article published in Science,Dart and colleagues reported that colonic T cells expressing the Vγ4 T-cell receptor(TCR)interact with epithelial butyrophilin-like(BTNL)proteins BTNL3 and BTNL8 in healthy individuals,and they observed a depletion of Vγ4 T cells in inflammatory bowel diseases with renormalization associated with disease remission.1 This paper identifies the BTNL/Vγ4 axis as a new disease modifier in IBD.
