GroupEnvoy: A Conversational Agent Speaking for the Outgroup to Foster Intergroup Relations
Koken Hata, Hengxuan Qin, Rintaro Chujo +3
Conversational agents have the potential to support intergroup relations when psychological or linguistic barriers prevent direct interaction. Based on intergroup contact theory, w…
PaperWave: Listening to Research Papers as Conversational Podcasts Scripted by LLM
Yuchi Yahagi, Rintaro Chujo, Yuga Harada +3
Listening to audio content, such as podcasts and audiobooks, is one way for people to engage with knowledge. Listening affords people more mobility than reading by seeing, thereby…
Formulas for the -mass on -currents with coefficients in
Julius Lohmann, Bernhard Schmitzer, Benedikt Wirth
We consider the minimization of the -mass over normal -currents in with coefficients in and prescribed boundary. This optimization is known as m…
Can AI with High Reasoning Ability Replicate Human-like Decision Making in Economic Experiments?
Ayato Kitadai, Sinndy Dayana Rico Lugo, Yudai Tsurusaki +2
Economic experiments offer a controlled setting for researchers to observe human decision-making and test diverse theories and hypotheses; however, substantial costs and efforts ar…
Site-Specific Ground Motion Generative Model for Crustal Earthquakes in Japan Based on Generative Adversarial Networks
Yuma Matsumoto, Taro Yaoyama, Sangwon Lee +2
We develop a site-specific ground-motion model (GMM) for crustal earthquakes in Japan that can directly model the probability distribution of ground motion acceleration time histor…
Higher time-derivative theories from space-time interchanged integrable field theories
Andreas Fring, Takano Taira, Bethan Turner
We compare a relativistic and a nonrelativistic version of Ostrogradsky's method for higher-time derivative theories extended to scalar field theories and consider as an alternativ…
Spatio-temporal reconstruction of substance dynamics using compressed sensing in multi-spectral magnetic resonance spectroscopic imaging
Utako Yamamoto, Hirohiko Imai, Kei Sano +3
The objective of our study is to observe dynamics of multiple substances in vivo with high temporal resolution from multi-spectral magnetic resonance spectroscopic imaging (MRSI) d…
Non-Hermitian Quantum Fermi Accelerator
Andreas Fring, Takano Taira
We exactly solve a quantum Fermi accelerator model consisting of a time-independent non-Hermitian Hamiltonian with time-dependent Dirichlet boundary conditions. A Hilbert space for…
Optimal Controller and Security Parameter for Encrypted Control Systems Under Least Squares Identification
Kaoru Teranishi, Kiminao Kogiso
Encrypted control is a framework for the secure outsourcing of controller computation using homomorphic encryption that allows to perform arithmetic operations on encrypted data wi…
An expanding ring of the hypercompact HII region W49N:A2
Ryosuke Miyawaki, Masahiko Hayashi, Tetsuo Hasegawa
We present 250~GHz continuum and H29alpha line data toward W49N:A2, a hypercompact HII region ionized by an O9 star. The data obtained with ALMA at a resolution of ~0"05 (600 au) c…
Towards Provably Secure Encrypted Control Using Homomorphic Encryption
Kaoru Teranishi, Kiminao Kogiso
Encrypted control is a promising method for the secure outsourcing of controller computation to a public cloud. However, a feasible method for security proofs of control has not ye…
Low-latency adiabatic quantum-flux-parametron circuit integrated with a hybrid serializer/deserializer
Yuki Hironaka, Taiki Yamae, Christopher L. Ayala +2
Adiabatic quantum-flux-parametron (AQFP) logic is an ultra-low-power superconductor logic family. AQFP logic gates are powered and clocked by dedicated clocking schemes using ac ex…
Moduli spaces for PT-regularized solitons
Francisco Correa, Andreas Fring, Takanobu Taira
We construct and analyse the moduli space (collective coordinates) for a classical field theory in 1 + 1 dimensions that possesses complex stable multi-soliton solutions with real…
Data structures for computing unique palindromes in static and non-static strings
Takuya Mieno, Mitsuru Funakoshi
A palindromic substring of a string is said to be a shortest unique palindromic substring (SUPS) in for an interval if is a shortest palindro…
Evolution of global development cooperation: An analysis of aid flows with hierarchical stochastic block models
Koji Oishi, Hiroto Ito, Yohsuke Murase +2
Despite considerable scholarly attention on the institutional and normative aspects of development cooperation, its longitudinal dynamics unfolding at the global level have rarely…
A New Extension of Chubanov's Method to Symmetric Cones
Shin-ichi Kanoh, Akiko Yoshise
We propose a new variant of Chubanov's method for solving the feasibility problem over the symmetric cone by extending Roos's method (2018) of solving the feasibility problem over…
Redshift identification of X-ray selected active galactic nuclei in the J1030 field: searching for large-scale structures and high-redshift sources
Stefano Marchesi, Marco Mignoli, Roberto Gilli +23
We publicly release the spectroscopic and photometric redshift catalog of the sources detected with Chandra in the field of the =6.3 quasar SDSS J1030+0525. This is currently th…
Input-Output History Feedback Controller for Encrypted Control with Leveled Fully Homomorphic Encryption
Kaoru Teranishi, Tomonori Sadamoto, Kiminao Kogiso
Protecting the parameters, states, and input/output signals of a dynamic controller is essential for securely outsourcing its computation to an untrusted third party. Although a fu…
Sensitivity of string compressors and repetitiveness measures
Tooru Akagi, Mitsuru Funakoshi, Shunsuke Inenaga
The sensitivity of a string compression algorithm asks how much the output size for an input string can increase when a single character edit operation is performed…
On the continuity of half-plane capacity with respect to Carathéodory convergence
Takuya Murayama
We study the continuity of half-plane capacity as a function of boundary hulls with respect to the Carathéodory convergence. In particular, our interest lies in the case that hulls…
