Covariance Matrix Estimation for High-Dimensional Interval-Valued Data with Positive Definiteness
Wan Tian, Wenhao Cui, Rui Zhang +3
In the realm of high-dimensional data analysis, the estimation of covariance matrices is a fundamental task, and this holds true for interval-valued data as well. However, there is…
New record in optical gain and room-temperature nanolasers in multiple wavelengths in 2D ErOCl single crystals
Shipeng Yao, Hao Sun, Zhang Liang +5
Erbium-based materials have long been recognized for their important telecom-band applications, yet their widespread adoption in integrated optoelectronics has been hindered by two…
Virtual Polarization Elements for Spatially Varying Jones Matrix Transformations on a Free-Space Plane
Mingyue Wang, Jiayuan Wang
Precise control over the spatial and polarization properties of light is foundational for advanced photonic systems, yet most conventional approaches are constrained to local, cont…
Unseen Attack Detection in Software-Defined Networking Using a BERT-Based Large Language Model
Mohammed N. Swileh, Shengli Zhang
Software defined networking (SDN) represents a transformative shift in network architecture by decoupling the control plane from the data plane, enabling centralized and flexible m…
