Byzantine-Robust Federated Learning over Ring-All-Reduce Distributed Computing

Kavli Affiliate: Jia Liu | First 5 Authors: Minghong Fang, Zhuqing Liu, Xuecen Zhao, Jia Liu, | Summary: Federated learning (FL) has gained attention as a distributed learning paradigm for its data privacy benefits and accelerated convergence through parallel computation. Traditional FL relies on a server-client (SC) architecture, where a central server coordinates multiple clients […]

Cosmological Consequences of Domain Walls Biased by Quantum Gravity

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yann Gouttenoire, Stephen F. King, Rishav Roshan, Xin Wang, Graham White | Summary: One of the simplest standard model extensions leading to a domain wall network is a real scalar $S$ with a $mathcal{Z}_2$ symmetry spontaneously broken during universe evolution. Motivated by the swampland program, we explore […]

Three-dimensional core-collapse supernova models with phenomenological treatment of neutrino flavor conversions

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~10^51 erg depending on the critical density for the onset of flavor […]

On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Yue Nan, Masahiro Takada, , | Summary: We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(theta)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show […]

Global symmetries of quantum lattice models under non-invertible dualities

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Yuan Miao, Masahito Yamazaki, , | Summary: Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group. When the […]

The energy dependence of cluster size and its physical processes in the proton measurement with TimePix3 silicon detector

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Naoki Itoh, Hugo Allaire, Tokihiro Ikeda, Shunsaku Nagasawa, Shinji Okada | Summary: We investigated the energy dependence of the number of triggered pixels, or cluster size, when charged particles are detected using the TimePix3 detector with a silicon sensor. We measured protons in the range of 1.5~3.3 […]
