It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft íray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft íray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-íray repeater (SGR) bursts were detected in íray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.   On the Derivation of Geometric Optical Kernels for Directional Thermal Radiation 期刊论文  OAI收割 EARTH AND SPACE SCIENCE, 2020, 卷号: 7, 期号: 1, 页码: 13 作者:  Liu, Xiangyang;  Tang, Bo-Hui;  Li, Zhao-Liang;  Zhang, Xia;  Shang, Guofei   |  收藏  |  浏览/下载：23/0  |  提交时间：2020/05/19 thermal radiation directionality  geometric optical model  kernel function  component temperature difference  land surface temperature   Glucose biosensor using fluorescence quenching with chitosan-modified graphene oxide 期刊论文  OAI收割 MICRO & NANO LETTERS, 2019, 卷号: 14, 期号: 3, 页码: 344-348 作者:  Li, WJ;  Jiang, TT;  Pu, Y;  Jiao, XD;  Tan, WQ   |  收藏  |  浏览/下载：47/0  |  提交时间：2020/07/08 biochemistry  biosensors  nanosensors  nanofabrication  fluorescence  molecular biophysics  radiation quenching  chemical sensors  sugar  proteins  biomedical optical imaging  graphene compounds  GO-CS  low concentrations  competitive binding  maltose-binding protein  recombinant phycocyanin  far-red fluorescence  MBP-rPC  rPC emission  rPC fluorescence  linear detection range  glucose biosensor  fluorescence quenching  chitosan-modified graphene oxide  low-molecular-weight chitosan  glucose detection  fluorescence resonance energy transfer  graphene oxide nanomaterial  mass 0  1 mg to 1  0 mg  CO   Numerical analysis of thermal radiation noise of shock layer over an infrared optical dome at near-ground altitudes 期刊论文  OAI收割 INFRARED PHYSICS & TECHNOLOGY, 2019, 卷号: 97, 页码: 74-84 作者:  He, Zhihong;  Niu, Qinglin;  Gao, Peng;  Yuan, Zhichao;  Dong, Shikui   |  收藏  |  浏览/下载：62/0  |  提交时间：2019/06/20 Radiation noise  Infrared radiation  Optical dome  Conjugate heat transfer  Trace species
