Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Haotian Fan, Xiaoxia Hou, Yitian Xu, Tao Li | Summary: Measuring the perceptual quality of images automatically is an essential task in the area of computer vision, as degradations on image quality can exist in many processes from image acquisition, transmission to enhancing. Many Image […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Shiyan Zhong, Shuo Li, Peter Berczik, Rainer Spurzem, | Summary: Tidal disruption of stars in dense nuclear star clusters containing supermassive central black holes (SMBH) is modeled by high-accuracy direct N-body simulation. Stars getting too close to the SMBH are tidally disrupted and a tidal disruption event […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Samuel W. Yee, Joshua N. Winn, Joel D. Hartman, Joseph E. Rodriguez, George Zhou | Summary: We report the discovery of ten short-period giant planets (TOI-2193A b, TOI-2207 b, TOI-2236 b, TOI-2421 b, TOI-2567 b, TOI-2570 b, TOI-3331 b, TOI-3540A b, TOI-3693 b, TOI-4137 b). All […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Zhifang Zhang, , , | Summary: Piggybacking design has been widely applied in distributed storage systems since it can greatly reduce the repair bandwidth with small sub-packetization. Compared with other existing erasure codes, piggybacking is more convenient to operate and the I/O cost is lower. […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Minghui Pang, Qiuming Zhu, Cheng-Xiang Wang, Zhipeng Lin, Junyu Liu | Summary: Path probability prediction is essential to describe the dynamic birth and death of propagation paths, and build the accurate channel model for air-to-ground (A2G) communications. The occurrence probability of each path is complex and time-variant […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jiayu Mao, Haibo Yang, Peiwen Qiu, Jia Liu, Aylin Yener | Summary: Over-the-air federated learning (OTA-FL) has emerged as an efficient mechanism that exploits the superposition property of the wireless medium and performs model aggregation for federated learning in the air. OTA-FL is naturally sensitive to wireless […]
Kavli Affiliate: Erin Kara | First 5 Authors: Kishalay De, Ilya Mereminskiy, Roberto Soria, Charlie Conroy, Erin Kara | Summary: We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using data from the Palomar Gattini-IR survey, we identify a spatially and temporally […]

Kavli Affiliate: Kevin Reil | First 5 Authors: Joseph Harry Silber, Parker Fagrelius, Kevin Fanning, Michael Schubnell, Jessica Nicole Aguilar | Summary: A system of 5,020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically re-target their optical fibers every 10 – 20 minutes, each […]
