    A Spatial Sigma-Delta Approach to Mitigation of Power Amplifier Distortions in Massive MIMO Downlink

    A Spatial Sigma-Delta Approach to Mitigation of Power Amplifier Distortions in Massive MIMO Downlink by Yatao Liu, Mingjie Shao, Wing-Kin Ma

    Published 2025-01-01

    In massive multiple-input multiple-output (MIMO) downlink systems, the physical implementation of the base stations (BSs) requires the use of cheap and power-efficient power amplifiers (PAs) to avoid high hardware cost and high power consumption. However, such PAs usually have limited linear amplifi...

    Impact of different perioperative dexmedetomidine administration regimens on postoperative sleep quality in gastrointestinal tumor resection: a randomized controlled trial

    Impact of different perioperative dexmedetomidine administration regimens on postoperative sleep quality in gastrointestinal tumor resection: a randomized controlled trial by Chengying Ji, Xiaodong Su, Chaohui Gao, Qijing Liu, Ying Liu, Qian Fu, Boxiong Gao, Jiayi Xie, Bokang Yang, Jinxiang Xie, Huping Song, Yatao Liu

    Published 2025-07-01

    Introduction: Perioperative sleep disorders constitute a recognized risk factor for multiple postoperative complications. Although dexmedetomidine (DEX) has been clinically employed to enhance perioperative sleep quality, its optimal administration protocol for postoperative sleep improvement remain...
