Semantic Incompleteness of Liberman et al. (2020)'s Hilbert-style System for Term-modal Logic K with Equality and Non-rigid Terms
Takahiro Sawasaki
In this paper, we prove the semantic incompleteness of the Hilbert-style system for the minimal normal term-modal logic with equality and non-rigid terms that was proposed in Liber…
Minimal dark matter in grand unification
Takashi Toma
Minimal dark matter is an attractive candidate for dark matter because it is stabilized without the need to impose additional symmetries. It is known that the quintuplet…
Cosmological scenario based on the first and second laws of thermodynamics: Thermodynamic constraints on a generalized cosmological model
Nobuyoshi Komatsu
The first and second laws of thermodynamics should lead to a consistent scenario for discussing the cosmological constant problem. In the present study, to establish such a thermod…
Grassmann tensor renormalization group for the massive Schwinger model with a term using staggered fermions
Hayato Kanno, Shinichiro Akiyama, Kotaro Murakami +1
We use the Grassmann tensor renormalization group method to investigate the Schwinger model with the staggered fermions in the presence of a periodic term in a bro…
Gill and Massar type bound for estimation of channel
Koichi Yamagata
In the estimation for a parametric family of quantum state on a Hilbert space , the Gill and Massar bound is known as a lower bound of weighted traces of covariances o…
Evolution of X-ray and optical rapid variability during the low/hard state in the 2018 outburst of MAXI J1820+070 = ASASSN-18ey
Mariko Kimura, Hitoshi Negoro, Shinya Yamada +3
We performed shot analyses of X-ray and optical sub-second flares observed during the low/hard state of the 2018 outburst in MAXI J1820070. Optical shots were less spread than X…
Excitation frequency dependence of noise and minimum detectable force in amplitude-modulation atomic force microscopy
Kenichi Umeda, Noriyuki Kodera
Atomic force microscopy (AFM) is a versatile nanoscale imaging technique. Since its spatiotemporal resolution is fundamentally limited by the minimum detectable force (MDF) arising…
Multiwavelength Afterglow Analysis of GRB 221009A: Unveiling the Evolution of a Cooling Break in a Wind-like Medium
Donggeun Tak, Z. Lucas Uhm, Gregory S. H. Paek +8
Gamma-ray bursts (GRBs) are the most energetic explosions in the universe, and their afterglow emission provides an opportunity to probe the physics of relativistic shock waves in…
Quantized neural network for complex hologram generation
Yutaka Endo, Minoru Oikawa, Timothy D. Wilkinson +2
Computer-generated holography (CGH) is a promising technology for augmented reality displays, such as head-mounted or head-up displays. However, its high computational demand makes…
Direct imaging of carbohydrate stereochemistry
Shuning Cai, Joakim S. Jestilä, Peter Liljeroth +1
Carbohydrates, essential biological building blocks, exhibit functional mechanisms tied to their intricate stereochemistry. Subtle stereochemical differences, such as those between…
The Density and Ionization Profile of Optically Dark and High Redshift GRBs Probed by X-ray Absorption
Eka Puspita Arumaningtyas, Hasan Al Rasyid, Maria Giovanna Dainotti +1
The X-ray column density (NHX) of gamma-ray bursts (GRBs) can probe the local environment of their progenitors over a wide redshift range. Previous work has suggested an increasing…
Isolated circular orders on free products of cyclic groups
Chihaya Jibiki, Shuhei Maruyama
In this paper, we construct countably many isolated circular orders on the free products of cyclic groups. More…
Precise large-scale chemical transformations on surfaces: deep learning meets scanning probe microscopy with interpretability
Nian Wu, Markus Aapro, Joakim S. Jestilä +9
Scanning Probe Microscopy (SPM) techniques have shown great potential in fabricating nanoscale structures endowed with exotic quantum properties achieved through various manipulati…
The horocyclic metric on Teichm{ü}ller spaces
Hideki Miyachi, Ken'Ichi Ohshika, Athanase Papadopoulos
In his paper Minimal stretch maps between hyperbolic surfaces, William Thurston defined a norm on the tangent space to Teichm{ü}ller space of a hyperbolic surface, which he called…
The Second-Level Preheating
Norma Sidik Risdianto, Apriadi Salim Adam, Lalu Zamakhsyari
This paper proposes two levels of preheating for the inflaton that is non-minimally coupled with gravity. The first level, later named by the quadratic regime, corresponds to the m…
Holographic thermodynamic relation for dissipative and non-dissipative universes in a flat FLRW cosmology
Nobuyoshi Komatsu
To clarify a holographic modified thermodynamic relation, the present study applies a general formulation for cosmological equations in a flat FLRW universe to the first law of the…
Weight Enumerators of codes over and over
A. K. M. Selim Reza, Manabu Oura, Nur Hamid
Weight enumerators are important tools for deciphering the algebraic structure of the related code spaces and for understanding group actions on these spaces. Our study focuses on…
Quantitative Formulation of Frequency-Dependent Average Force in AM-AFM
Kenichi Umeda, Karen Kamoshita, Noriyuki Kodera
Amplitude-modulation atomic force microscopy (AM-AFM) measures nanoscale surface structures by detecting changes in the cantilever oscillation amplitude, contributing to materials…
Lattice-guided growth of dense arrays of aligned transition metal dichalcogenide nanoribbons with high catalytic reactivity

Transition metal dichalcogenides (TMDs) exhibit unique properties and potential applications when reduced to one-dimensional (1D) nanoribbons (NRs), owing to quantum confinement an…
The random walk of intermittently self-propelled particles
Agniva Datta, Carsten Beta, Robert Großmann
