Electroweak baryogenesis in the three-loop neutrino mass model with dark matter
Mayumi Aoki, Kazuki Enomoto, Shinya Kanemura
Baryon asymmetry of the Universe is evaluated in the model originally proposed in Phys. Rev. Lett. 102 (2009) 051805, where Majorana masses of neutrinos are generated via three-loo…
Social-Aware Clustered Federated Learning with Customized Privacy Preservation
Yuntao Wang, Zhou Su, Yanghe Pan +3
A key feature of federated learning (FL) is to preserve the data privacy of end users. However, there still exist potential privacy leakage in exchanging gradients under FL. As a r…
Phenomenological and cosmological implications of a scotogenic three-loop neutrino mass model
Asmaa Abada, Nicolás Bernal, Antonio E. Cárcamo Hernández +3
We propose a scotogenic model for generating neutrino masses through a three-loop seesaw. It is a minimally extended inert doublet model with a spontaneously broken global symmetry…
Horizon thermodynamics and cosmological equations: A holographic-like connection between thermostatistical quantities on a cosmological horizon and in the bulk
Nobuyoshi Komatsu
Horizon thermodynamics is expected to be related to the effective energy based on the energy density calculated from the Friedmann equation for a Friedmann--Robertson--Walker (FRW)…
Single-Fingered Reconfigurable Robotic Gripper With a Folding Mechanism for Narrow Working Spaces
Toshihiro Nishimura, Tsubasa Muryoe, Yoshitatsu Asama +3
This letter proposes a novel single-fingered reconfigurable robotic gripper for grasping objects in narrow working spaces. The finger of the developed gripper realizes two configur…
1-degree-of-freedom Robotic Gripper With Infinite Self-Twist Function
Toshihiro Nishimura, Yosuke Suzuki, Tokuo Tsuji +1
This study proposed a novel robotic gripper that can achieve grasping and infinite wrist twisting motions using a single actuator. The gripper is equipped with a differential gear…
Sensing and Control of Friction Mode for Contact Area Variable Surfaces (Friction-variable Surface Structure)
Seita Nojiri, Akihiko Yamaguchi, Yosuke Suzuki +2
Robotic hands with soft surfaces can perform stable grasping, but the high friction of the soft surfaces makes it difficult to release objects, or to perform operations that requir…
A minor extension of the logistic equation for growth of word counts on online media: Parametric description of diversity of growth phenomena in society
Hayafumi Watanabe
To understand the growing phenomena of new vocabulary on nationwide online social media, we analyzed monthly word count time series extracted from approximately 1 billion Japanese…
The -support as a micro-support
Tomohiro Asano, Stéphane Guillermou, Vincent Humilière +2
We prove that for any element in the completion of the space of smooth compact exact Lagrangian submanifolds of a cotangent bundle equipped with the spectral distance, the -…
All-mode Renormalization for Tensor Network with Stochastic Noise
Erika Arai, Hiroshi Ohki, Shinji Takeda +1
In usual (non-stochastic) tensor network calculations, the truncated singular value decomposition (SVD) is often used for approximating a tensor, and it causes systematic errors. B…
Reaction-induced molecular dancing and boosted diffusion of enzymes
Hiroyuki Kitahata, Alexander S. Mikhailov
A novel mechanism of reaction-induced active molecular motion, not involving any kind of self-propulsion, is proposed and analyzed. Because of the momentum exchange with the surrou…
Low-frequency quantum sensing
E. D. Herbschleb, I. Ohki, K. Morita +5
Exquisite sensitivities are a prominent advantage of quantum sensors. Ramsey sequences allow precise measurement of direct current fields, while Hahn-echo-like sequences measure al…
Water dimer driven DNA base superstructure with mismatched hydrogen-bonding
Shuning Cai, Lauri Kurki, Chen Xu +2
The existence of water dimers in equilibrium water vapor at room temperature and their anomalous properties revealed by recent studies suggest the benchmark role of water dimer in…
