A novel concept of orbital launch system in which all stages are reusable is presented. The first two stages called Midpoint Delivery System (MPDS) deliver the next stages to a midpoint.

We have detected, for the first time, Cepheid variables in the Sculptor Group spiral galaxy NGC 7793. From wide-field images obtained in the optical V and I bands on 56 nights in 2003-2005, we have discovered 17 long-period (24-62 days) Cepheids whose periods and mean magnitudes define tight period-luminosity relations... | Hemos detectado, por primera vez, variables Cefeidas en la galaxia espiral NGC 7793 del Grupo Escultor.

This paper considers a downlink ultra-dense heterogeneous cloud radio access network (H-CRAN) which guarantees seamless coverage and can provide high date rates. In order to reduce channel state information (CSI) feedback overhead, incomplete inter-cluster CSI is considered, i.e., each remote radio head (RRH) or macro ... | 本文研究了一种下行链路超密集异构云无线接入网络（H-CRAN），该网络可保证无缝覆盖并提供高速数据速率。为了降低信道状态信息（CSI）反馈开销，本文考虑不完整的跨簇CSI，即每个远程射频头端（RRH）或宏基站（MBS）仅测量其服务簇内用户设备（UE）的CSI。为减少导频开销，假设UE之间进行导频复用，从而导致簇内CSI不准确。随后，本文建立了一个两阶段优化问题。在第一阶段，提出一种导频调度算法，以最小化所有信道估计的均方误差（MSE）之和。具体而言，首先利用Dsatur算法确定所需的最少导频数量及一种可行的导频分配方案，然后根据定义的导频污染程度进行调整，以进一步优化性能。在第二阶段，基于第一阶段获得的导频分配结果，通过优化波束向量... | zh |
Successful applications of reinforcement learning in real-world problems often require dealing with partially observable states. It is in general very challenging to construct and infer hidden states as they often depend on the agent's entire interaction history and may require substantial domain knowledge.
