Direct detection of pseudo-Nambu-Goldstone dark matter with light mediator
Yoshihiko Abe, Takashi Toma
It has been found that a pseudo-Nambu-Goldstone boson dark matter suppresses the amplitude for elastic scattering with nuclei in non-relativistic limit, and thus can naturally evad…
Variable-Grasping-Mode Gripper With Different Finger Structures For Grasping Small-Sized Items
Tetsuyou Watanabe, Kota Morino, Yoshitatsu Asama +2
This letter presents a novel small gripper capable of grasping various types of small-sized items from flat surfaces for the assembly of small devices. Using a single actuator, the…
Towards robust and domain agnostic reinforcement learning competitions
William Hebgen Guss, Stephanie Milani, Nicholay Topin +26
Reinforcement learning competitions have formed the basis for standard research benchmarks, galvanized advances in the state-of-the-art, and shaped the direction of the field. Desp…
Vanishing or non-vanishing rainbow? Reduction formulas of electric dipole moment
Motoko Fujiwara, Junji Hisano, Takashi Toma
In this paper, we derive a simplified formula of electric dipole moments (EDMs) of a fermion. In the Standard Model, it is well-known that non-trivial cancellations between some ra…
Photonic neural field on a silicon chip: large-scale, high-speed neuro-inspired computing and sensing
Satoshi Sunada, Atsushi Uchida
Photonic neural networks have significant potential for high-speed neural processing with low latency and ultralow energy consumption. However, the on-chip implementation of a larg…
Using multidimensional speckle dynamics for high-speed, large-scale, parallel photonic computing
Satoshi Sunada, Kazutaka Kanno, Atsushi Uchida
The recent rapid increase in demand for data processing has resulted in the need for novel machine learning concepts and hardware. Physical reservoir computing and an extreme learn…
