Lateral distributions of electrons in air showers initiated by photons of ultra high energies ( eV) obtained on the basis of numerical solution of adjoint cascade…
High Forbidden-to-resonance Line Ratio of OVII Discovered in the Cygnus Loop
H. Uchida, S. Katsuda, H. Tsunemi +5
Charge exchange (CX) is an important process in shock physics since it indicates an interaction between downstream ions and ambient neutral hydrogen, suggesting a presence of a col…
Rigid Foldability is NP-Hard
Hugo Akitaya, Erik D. Demaine, Takashi Horiyama +3
In this paper, we show that deciding rigid foldability of a given crease pattern using all creases is weakly NP-hard by a reduction from Partition, and that deciding rigid foldabil…
Strong-coupling formula for momentum-dependent susceptibilities in dynamical mean-field theory
Junya Otsuki, Kazuyoshi Yoshimi, Hiroshi Shinaoka +1
Computing momentum-dependent susceptibilities in the dynamical mean-field theory (DMFT) requires solving the Bethe-Salpeter equation, which demands large computational cost. Exploi…
COMET Phase-I Technical Design Report

We study ordered phases with broken translational symmetry in the half-filled three-orbital Hubbard model with antiferromagnetic Hund coupling by means of dynamical mean-field theo…
Application of isochronous mass spectrometry for the study of angular momentum population in projectile fragmentation reactions
X. L. Tu, A. Kelic-Heil, Yu. A. Litvinov +37
Isochronous mass spectrometry was applied to measure isomeric yield ratios of fragmentation reaction products. This approach is complementary to conventional gamma-ray spectroscopy…
Isochronous mass measurements of -shell nuclei from projectile fragmentation of Ni
Y. H. Zhang, P. Zhang, X. H. Zhou +33
Atomic masses of seven , -shell nuclei from V to Cu and two low-lying isomers, V () and Co (), have been measured with r…
Updated Core Libraries of the ALPS Project
Markus Wallerberger, Sergei Iskakov, Alexander Gaenko +13

Imitation Learning for Object Manipulation Based on Position/Force Information Using Bilateral Control
Tsuyoshi Adachi, Kazuki Fujimoto, Sho Sakaino +1
This study proposes an imitation learning method based on force and position information. Force information is required for precise object manipulation but is difficult to obtain b…
Bilateral Control of Two Finger Joints Using Functional Electrical Stimulation
Yuu Hasegawa, Tomoya Kitamura, Sho Sakaino +1
Bilateral control, a remote-control technique, is used to work at a distance. However, many existing bilateral control systems have two common problems: 1) it is difficult to creat…
An X-ray spectroscopic search for dark matter and unidentified line signatures in the Perseus cluster with Hitomi
Takayuki Tamura, Andrew C. Fabian, Poshak Gandhi +14
We present results of a search for unidentified line emission and absorption signals in the 2-12keV energy band of spectra extracted from Perseus Cluster core region observations o…
On the nonlinear Brascamp-Lieb inequality
Jonathan Bennett, Neal Bez, Stefan Buschenhenke +2
We prove a nonlinear variant of the general Brascamp-Lieb inequality. Instances of this inequality are quite prevalent in analysis, and we illustrate this with substantial applicat…

We present the results of the search for ultra-high-energy photons with nine years of data from the Telescope Array surface detector. A multivariate classifier is built upon 16 rec…
Quadratic unconstrained binary optimization formulation for rectified-linear-unit-type functions
Go Sato, Makiko Konoshima, Takuya Ohwa +2
We propose a quadratic unconstrained binary optimization (QUBO) formulation of rectified linear unit (ReLU) type functions. Different from the q-loss function proposed by Denchev e…
Estimation of Relationship between Stimulation Current and Force Exerted during Isometric Contraction
Tomoya Kitamura, Yuu Hasegawa, Sho Sakaino +1
