    On-axis Polarization Calibration of the FAST L-band 19-beam Receiver

    On-axis Polarization Calibration of the FAST L-band 19-beam Receiver द्वारा Tao-Chung Ching, Carl Heiles, Di Li, Timothy Robishaw, Xunzhou Chen, Lingqi Meng, You-Ling Yue, Lei Qian, Hong-Fei Liu

    प्रकाशित 2025-01-01

    We present the polarization calibration of the 19-beam receiver at 1420 MHz within the full illumination of the Five-hundred-meter Aperture Spherical radio Telescope from 2018 October to 2023 March. We perform spider observations to characterize the on-axis Mueller matrix of the central beam. The ca...

    Cholinergic basal forebrain neurons regulate vascular dynamics and cerebrospinal fluid flux

    Cholinergic basal forebrain neurons regulate vascular dynamics and cerebrospinal fluid flux द्वारा Kai-Hsiang Chuang, Xiaoqing Alice Zhou, Ying Xia, Zengmin Li, Lei Qian, Eamonn Eeles, Grace Ngiam, Jurgen Fripp, Elizabeth J. Coulson

    प्रकाशित 2025-06-01

    Abstract Brain waste is cleared via a cerebrospinal fluid (CSF) pathway, the glymphatic system, whose dysfunction may underlie many brain conditions. Previous studies show coherent vascular oscillation, measured by blood oxygenation level-dependent (BOLD) fMRI, couples with CSF inflow to drive fluid...

    Discovery of a Periodic Radio Signal from the Formerly Radio-quiet γ-Ray Pulsar J0359+5414 with FAST

    Discovery of a Periodic Radio Signal from the Formerly Radio-quiet γ-Ray Pulsar J0359+5414 with FAST द्वारा Ruobin Ding, Zhichen Pan, Ralph P. Eatough, Shuangqiang Wang, Yujie Lian, Shunshun Cao, Renxin Xu, Lei Qian, Tingting Lin, Haiyan Zhang, Shuo Cao

    प्रकाशित 2025-01-01

    In this paper, we report the detection of a periodic radio signal from the radio-quiet γ -ray pulsar PSR J0359+5414, using the Five-hundred-meter Aperture Spherical radio Telescope. This pulsar has a rotational period of 79.42 ms determined in the γ -ray band by the Fermi satellite. Our results show...

    RBM14 enhances transcriptional activity of p23 regulating CXCL1 expression to induce lung cancer metastasis

    RBM14 enhances transcriptional activity of p23 regulating CXCL1 expression to induce lung cancer metastasis द्वारा Wen Zhang, Yulin Peng, Meirong Zhou, Lei Qian, Yilin Che, Junlin Chen, Wenhao Zhang, Chengjian He, Minghang Qi, Xiaohong Shu, Manman Tian, Xiangge Tian, Yan Tian, Sa Deng, Yan Wang, Xiaokui Huo, Zhenlong Yu, Xiaochi Ma

    प्रकाशित 2025-06-01

    Metastasis serves as an indicator of malignancy and is a biological characteristic of carcinomas. Epithelial–mesenchymal transition (EMT) plays a key role in the promotion of tumor invasion and metastasis and in the enhancement of tumor cell aggressiveness. Prostaglandin E synthase 3 (p23) is a coch...

    प्रकाशित 2025-01-01

    By 2025 January, 60 pulsars were discovered by the Five-hundred-meter Aperture Spherical radio Telescope globular cluster (GC) pulsar survey (GC FANS), with spin periods spanning 1.98–3960.72 ms. Of these, 55 are millisecond pulsars (MSPs; P  < 30 ms), while 35 are binaries with orbital periods s...
