Optimization of noncollinear magnetic ordering temperature in Y-type hexaferrite by machine learning

Kavli Affiliate: Long Zhang | First 5 Authors: Yonghong Li, Jing Zhang, Linfeng Jiang, Long Zhang, Yugang Zhang | Summary: Searching the optimal doping compositions of the Y-type hexaferrite Ba2Mg2Fe12O22 remains a long-standing challenge for enhanced non-collinear magnetic transition temperature (TNC). Instead of the conventional trial-and-error approach, the composition-property descriptor is established via a data […]

Rateless Stochastic Coding for Delay-constrained Semantic Communication

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Rulong Wang, Yong Xiao, , | Summary: We consider the problem of joint source-channel coding with distortion and perception constraints from a rateless perspective, the purpose of which is to settle the balance between reliability (distortion/perception) and effectiveness (rate) of transmission over uncertain channels. We […]
