太空新基建——我国商业航天及卫星互联网技术初探
随着航天产业与低成本可回收火箭技术的进步,国内外卫星互联网技术快速发展,以SpaceX为代表的猎鹰9号火箭和Starlink星座发展迅速,在过去短短几年内,SpaceX公司在500Km低地球轨道部署了近万颗卫星。在国内,受限于传统火箭运力不足,我国卫星互联网基建速度存在规划超前和建设滞后的剪刀差。近年来以上海垣信卫星和中国星网为代表的国内卫星互联网公司加速追赶。卫星互联网构建是一项系统工程,涉及火箭运力、轨道频谱、微波激光通信等多种技术。本讲座从Starlink技术、可回收火箭技术、卫星互联网组网、卫星星间激光通信、星载人工智能等几个方面对我国商业航天及卫星互联网技术做简要介绍。

Exploring the inverse problem from the correlation function for system with two open bottom quarks
We perform a study of two-channel correlation functions for system with two open bottom quarks using an extension of the local hidden gauge approach which provides the interaction from the exchange of light vector mesons and gives rise to a bound state of these components in I=0 with a binding energy of about 21 MeV. After that, we face the inverse problem of determining the low energy observables, scattering length and effective range for each channel, the possible existence of a bound state, and, if found, the couplings of such a state to each component as well as the molecular probabilities of each of the channels. We use the bootstrap method to determine these magnitudes and find that, with errors in the correlation function typical of present experiments, we can determine all these magnitudes with acceptable precision. In addition, the size of the source function of the experiment from where the correlation functions are measured can be also determined with a high precision.

pi-pi谱的一般描述和f0(980)的结构讨论
The nature of light scalar mesons remains an unsolved puzzle in hadron physics, complicated by their large widths and controversial partonic structure. This report will first introduce the debates surrounding the structure of the f0(980). By incorporating the two-pion light-cone distribution amplitudes (2pi-DAs), the report will subsequently elucidate the multi-particle state dominance picture of f0(980) the in the final states of semileptonic charmed meson decays. This picture, along with the simple structure dominance behavior of the f0(980) in meson decays, reveals the diverse emergent phenomena exhibited by light scalar mesons in exclusive processes at different characteristic energy scales. The discussion in this report will closely integrate the latest measurements from the BESIII experiment and traditional cascade decay research approaches.

量子高斯网络可制备纠缠态的函数特征
量子高斯网络是由空间中独立的节点及连接这些节点的高斯量子操作组成,各个节点之间共享纠缠高斯态。在对节点处执行量子操作或者量子测量时,会将节点处共享的量子纠缠传到至整个网络,形成多体纠缠。刻画这种多体纠缠的性质是量子网络中的一个有趣问题,不仅影响到量子网络的技术发展,而且能够增进人们对网络情形下多体纠缠的理解。我们用Renyi-熵诱导的多体互信息、压榨纠缠度量的泛化等信息学函数给出了可制备纠缠高斯态的函数特征。这些特征显示了网络结构对可制备纠缠态具有很强的约束性,这与标准的单一多体纠缠完全不同。

生态文明呼唤一种后现代的生态人
生态人是一种生命力饱满、生生不息、具有高生态智慧和生态意识的人。他们深刻理解万物互相关联的内在联系,尊重自然法则,反对以牺牲自然为代价的发展方式;他们对自然、他人、时代、美有深切的感知与共情,具有“共命意识”,并以此承担起道义责任。生态人不仅有理想、有情怀,还具备实际能力,能打通自然、社会、实践与生命的界限,是通达之人。他们生活简朴、从容淡定、贴近自然,是“踏实的存在”;同时坚守浪漫理想,活出诗意人生。生态文明的建设,离不开生态人的大规模涌现。

新一代 新感知——释读全球艺术转向与当代艺术史写作
在全球化深入发展的当下,艺术史研究正经历着深刻的范式转型,“全球转向” 作为其中极具影响力的学术思潮,打破了传统艺术史研究的地域局限与单一视角,为我们重新审视艺术的跨文化传播、交流与融合提供了全新思路。而翻译,作为跨文化对话的重要桥梁,不仅是语言层面的转换,更是思想与文化的传递与解读,对理解“全球转向” 背景下的艺术创作及写作具有关键意义。
