本次演讲将分享复杂度受限容量可达的概念和研究进展，与传统复杂度不受限下多用户容量可达设计不同，本报告首先提出复杂度受限下容量可达科学问题及其潜在研究方向，然后给出复杂度受限下线性复杂度接收机设计的高谱效传输实例，并将其推广到免调度（Grant-free）海量随机接入应用场景，最后对MIMO最大似然（Maximum likelihood）检测一般性经典复杂度问题进行探讨。

在现代的时域天文学领域中，随着时域巡天设备的升级，大量的暂现源被发现。中等亮度的暂现源是一类非常特殊且稀少的暂现源，其亮度介于典型的超新星和经典的新星之间，目前基本处于唯象学的研究阶段。我将主要介绍此类暂现源的研究进展。另外，稻城是我们国家的优良天文台台址，我也将提及基于稻城无名山台址的R2Pub（from Research to Public outreach）大视场双筒望远镜的相关情况。

Stochastic temperature distribution should be carefully inspected in the thermal-failure design of heterogeneous solids with unexpected random energy excitations. Stochastic multiscale modeling for these problems involve uncertain thermal conductivity, high-dimensional and multiscale features, which remains limitation of prohibitive computation. In this paper, we propose an multi-modes based constrained energy minimization generalized multiscale finite element method (MCEM-GMsFEM), which can transform the original stochastic multiscale model into a series of recursive multiscale models sharing the same deterministic material parameters by multiscale analysis. Thus, MCEM-GMsFEM reveals an inherent low-dimensional representation in random space, and is designed to effectively reduce the complexity of repeated computation of discretized multiscale systems. In addition, the convergence analysis is established, and the optimal error estimates are derived. Finally, several typical stochastic disturbance on the mean value of uncertain thermal conductivity are considered to validate the theoretical results in the numerical examples. The numerical results indicate that the multi-modes multiscale model is a robust integrated method with the excellent performance.
