The detection of a coincident bright X-ray burst represents the first observed multiwavelength counterpart of an FRB. However, the search for similar emission at optical wavelengths has been hampered by the high inferred extinction on the line of sight. Here, we present results from the first search for second-timescale emission from the source at near-infrared (NIR) wavelengths using the Palomar Gattini-IR observing system in the J band, enabled by a novel detector readout mode that allows short exposure times of ?0.84 s with 99.9% observing efficiency. With a total observing time of ?12 hr (?47,728 images) during its 2020 outburst, we place median 3Ҡlimits on the second-timescale NIR fluence of ?18 Jy ms (13.1 AB mag). The corresponding extinction-corrected limit is ?125 Jy ms for an estimated extinction of AJ = 2.0 mag. Our observations were sensitive enough to easily detect an NIR counterpart of FRB 200428 if the NIR emission falls on the same power law as observed across its radio to X-ray spectrum. We report nondetection limits from epochs of four simultaneous X-ray bursts detected by the Insight-HXMT and NuSTAR telescopes during our observations. These limits provide the most stringent constraints to date on fluence of flares at 1014 Hz, and constrain the fluence ratio of the NIR emission to coincident X-ray bursts to RNIR ? 0.025 (fluence index ?0.35).   AN END-TO-END SIMULATION OF OCEAN SALINITY USING L/S/C TRI-FREQUENCY RADIOMETER FOR WATER CYCLE OBSERVATION MISSION (WCOM) 会议论文  OAI收割 Valencia, SPAIN, JUL 22-27, 2018 作者:  Li, Yan;  Liu, Hao   |  收藏  |  浏览/下载：21/0  |  提交时间：2019/01/31 Water Cycle Observation Mission (WCOM)  Interferometric Microwave Imager (IMI)  L/S/C band  Salinity  Brightness Temperature (TB)  Retrieval   Detection of Essential Tremor at the S-Band 期刊论文  OAI收割 IEEE JOURNAL OF TRANSLATIONAL ENGINEERING IN HEALTH AND MEDICINE-JTEHM, 2018, 卷号: 6 作者:  Yang, Xiaodong;  Shah, Syed Aziz;  Ren, Aifeng;  Fan, Dou;  Zhao, Nan   |  收藏  |  浏览/下载：47/0  |  提交时间：2018/10/10 S-band Sensing Technique  Essential Tremor  Biomedical Engineering   Tuning the band gap of cu(in,ga)se-2 thin films by simultaneous selenization/sulfurization 期刊论文  iSwitch采集 Materials letters, 2016, 卷号: 182, 页码: 114-117 作者:  Huang, Yongliang;  Han, Anjun;  Wang, Xian;  Liu, Xiaohui;  Liu, Zhengxin 收藏  |  浏览/下载：110/0  |  提交时间：2019/05/09 Cigs  Thin film  Simultaneous selenization/sulfurization  Tunable band gap  S incorporation   The network of causal interactions for beta oscillations in the pedunculopontine nucleus, primary motor cortex, and subthalamic nucleus of walking parkinsonian rats 期刊论文  OAI收割 EXPERIMENTAL NEUROLOGY, 2016, 卷号: 282, 期号: 2016, 页码: 27-36 作者:  Li, Min;  Zhou, Ming;  Wen, Peng;  Wang, Qiang;  Yang, Yong 收藏  |  浏览/下载：47/0  |  提交时间：2016/08/08 Parkinson's disease  Parkinsonian rats  Local field potentials  Beta band oscillations  Pedunculopontine nucleus  Primary motor cortex  Subthalamic nucleus   A SURE Based Sub-band Adaptive De-noising Method 会议论文  OAI收割 2016 2nd IEEE International Conference on Computer and Communications (ICCC 2016), Chengdu, China, October 14-17, 2016 作者:  Gong TR(宫铁瑞);  Yang ZJ(杨志家);  Wang GS(王庚善);  Jiao P(焦平) 收藏  |  浏览/下载：34/0  |  提交时间：2016/12/21 Wavelet denoising  sub-band adaptive denoising  Stein’s unbiased risk estimate (SURE)  minimization
