    Resource allocation algorithm for cognitive radio systems based on STAR-RIS with coupled phase shifts by LI Guoquan, XIONG Hao, XIE Zonglin, LIN Jinzhao

    Published 2024-11-01
    “…To address the issues of spectrum resource scarcity and limited communication quality, a scheme for a coupled phase-shift-based simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS)-assisted multi-ple-input single-output (MISO) cognitive radio system was proposed. …”

    Phase structure and optical properties of the de Sitter Spacetime with KR field based on the Lyapunov exponent by Yun-Zhi Du, Huai-Fan Li, Yu-Bo Ma, Qiang Gu

    Published 2025-01-01
    “…Abstract Since the spontaneously broken of the Lorentz symmetry in the gravity theory with the non-minimally coupling between the Kalb–Ramond (KR) field (that acquires a nonzero vacuum expectation value) and the Einstein gravity, there exists the exactly static and spherically symmetric black holes solutions related with the Lorentz violating parameter. Based on this, we consider the corresponding black hole solution in the de-Sitter (dS) spacetime with the KR field and investigate the thermodynamic properties in the expanded phase space through introducing the interplay entropy between the black hole and cosmological horizons. …”

    GPS Phase Integer Ambiguity Resolution Based on Eliminating Coordinate Parameters and Ant Colony Algorithm by Ning Liu, Shuangcheng Zhang, Xiaoli Wu, Yu Shen

    Published 2025-01-01
    “…When solving the float solution of ambiguity based on the double-difference model epoch by epoch, the common method for resolving the integer ambiguity needs to solve the coordinate parameter information, due to the influence of limited GNSS phase data observations. …”

    Constraining the Gamma-Ray Burst Jet Opening Angle Based on the Very Steep Decay Phase by Qian Xu, Dong-Jie Liu, Yuan-Chuan Zou

    Published 2025-01-01
    “…This study constrains the jet opening angles of GRBs by analyzing the very steep decay phase in the early X-ray afterglow. Using data from Swift/XRT, we identified GRBs with significant breaks in their light curves and applied a broken power-law model to describe the decay phases. …”
