Agentic metasurface design with self-correcting language-model systems

Bei Wu, Bo Xiong, Haiyao Luo, Yaqi Li et autres

Automated metasurface design is increasingly important, and recent advances in language-model systems are opening a route toward agentic optical design. Yet modern metasurface applications, from metalenses and holography to optical computing, require long design chains spanning modeling, simulation, coding, optimization and evaluation. …

Performance Analysis of Spatiotemporal 2-D Polar Codes for Massive MIMO With MMSE Receivers

Yaqi Li, Xiaohu You, Jiamin Li, Chen Ji et autres

With the evolution from 5G to 6G, ultra-reliable low-latency communication (URLLC) faces increasingly stringent performance requirements. Lower latency constraints demand shorter channel codeword length, which can severely degrade decoding performance. The massive multiple-input multiple-output (MIMO) system is considered a crucial technology to …

Energy-Efficient Duplex Mode Optimization for Network-Assisted Full-Duplex Cell-Free Massive MIMO Systems

Yaqi Li, Xiaoyu Sun, Jiamin Li, Pengcheng Zhu et autres

Network-Assisted Full-Duplex (NAFD) cell-free massive multiple-input multiple-output (CF-mMIMO) systems can improve the spectral efficiency (SE) by dynamically allocating the numbers of uplink (UL) and downlink (DL) remote antenna units (RAUs) to realize simultaneous UL and DL transmission without self-interference (SI). However, with …

ZIF-8-Modified Multifunctional Hydrogel Loading siRNA and DOX for Postoperative Therapy of Maxillofacial Osteosarcoma and Bone Repair

Jiamin Zhou, Guimei Lin, Xianglei Fu, Shengnan Qiu et autres

The primary clinical challenges associated with postoperative maxillofacial osteosarcoma include high mortality rates and significant local recurrence. Additionally, patients often exhibit substantial bone defects that are incapable of self-healing, necessitating the implantation of scaffolds. Multifunctional hydrogels, which enable sustained local release of …
