Kavli Affiliate: Jia Liu | First 5 Authors: Xin Zhang, Minghong Fang, Zhuqing Liu, Haibo Yang, Jia Liu | Summary: Federated learning (FL) has received a surge of interest in recent years thanks to its benefits in data privacy protection, efficient communication, and parallel data processing. Also, with appropriate algorithmic designs, one could achieve the […]
Kavli Affiliate: Jia Liu | First 5 Authors: Zhuqing Liu, Xin Zhang, Jia Liu, , | Summary: To increase the training speed of distributed learning, recent years have witnessed a significant amount of interest in developing both synchronous and asynchronous distributed stochastic variance-reduced optimization methods. However, all existing synchronous and asynchronous distributed training algorithms suffer […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, Dohyeong Kim, Taehyun Kim | Summary: We report an exceptional mid-infrared flare in the Seyfert 1.8 NGC 3786. In the multi-epoch data from the Wide-field Infrared Survey Explorer, the nuclear mid-infrared brightness of NGC 3786 appears to vary substantially […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Yonit Hochberg, Eric Kuflik, Kevin Langhoff | Summary: We introduce Super-Resonant Dark Matter, a model of self-interacting dark matter based on the low energy effective theory of supersymmetric QCD. The structure of the theory ensures a resonant enhancement of the self-interactions of the […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Carolyn Kierans, Tadayuki Takahashi, Gottfried Kanbach, , | Summary: Compton telescopes rely on the dominant interaction mechanism in the MeV gamma-ray energy range: Compton scattering. By precisely recording the position and energy of multiple Compton scatter interactions in a detector volume, a photon’s original direction and energy […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Doug Johnstone, Bhavana Lalchand, Steve Mairs, Hsien Shang, Wen Ping Chen | Summary: Short-duration flares at millimeter wavelengths provide unique insights into the strongest magnetic reconnection events in stellar coronae, and combine with longer-term variability to introduce complications to next-generation cosmology surveys. We analyze 5.5 years […]
Kavli Affiliate: Sara Seager | First 5 Authors: Richard French, Christophe Mandy, Richard Hunter, Ehson Mosleh, Doug Sinclair | Summary: Regular, low-cost Decadal-class science missions to planetary destinations will be enabled by high-{Delta}V small spacecraft, such as the high-energy Photon, and small launch vehicles, such as Electron, to support expanding opportunities for scientists and to […]
Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Eric D. Miller, Gregory Y. Prigozhin, Beverly J. LaMarr, Marshall W. Bautz, Richard F. Foster | Summary: To take advantage of high-resolution optics sensitive to a broad energy range, future X-ray imaging instruments will require thick detectors with small pixels. This pixel aspect ratio affects spectral […]
Kavli Affiliate: George Ricker | First 5 Authors: Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson, Andrea Bonfanti, Vardan Adibekyan | Summary: We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ($T = 8.5$ mag), high proper motion ($sim,200$ mas yr$^{-1}$), […]
Kavli Affiliate: Jing Wang | First 5 Authors: Zhenyu Ni, Jing Wang, Liying Kang, , | Summary: The $kK_{r+1}$ is the union of $k$ disjoint copies of $(r+1)$-clique. Moon [Canad. J. Math. 20 (1968) 95–102] and Simonovits [Theory of Graphs (Proc. colloq., Tihany, 1996)] independently showed that if $n$ is sufficiently large, then $K_{k-1}vee T_{n-k+1,r}$ […]
