SAVER: Stochastic Adaptive Variance-Driven Exploration and Reconstruction for Low-Dose Computed Tomography
Shunta Nonaga, Koji Tabata, Junya Honda +3
Computed Tomography (CT) is indispensable in clinical diagnostics, yet minimizing radiation dose without compromising image quality remains a critical challenge. Conventional low-d…
Risk-Averse Best Arm Set Identification with Fixed Budget and Fixed Confidence
Shunta Nonaga, Koji Tabata, Yuta Mizuno +1
Decision making under uncertain environments in the maximization of expected reward while minimizing its risk is one of the ubiquitous problems in many subjects. Here, we introduce…
Enumeration algorithms for combinatorial problems using Ising machines: When should we stop exploring energy landscapes?
Yuta Mizuno, Mohammad Ali, Tamiki Komatsuzaki
Combinatorial problems such as combinatorial optimization and constraint satisfaction problems arise in decision-making across various fields of science and technology. In real-wor…
Low-Dimensional Projection of Reactive Islands in Chemical Reaction Dynamics Using a Supervised Dimensionality Reduction Method
Ryoichi Tanaka, Yuta Mizuno, Takuro Tsutsumi +3
Transition state theory is a standard framework for predicting the rate of a chemical reaction. Although the transition state theory has been successfully applied to numerous chemi…
A Quantum Algorithm for Dynamic Mode Decomposition Integrated with a Quantum Differential Equation Solver
Yuta Mizuno, Tamiki Komatsuzaki
We present a quantum algorithm that analyzes time series data simulated by a quantum differential equation solver. The proposed algorithm is a quantum version of the dynamic mode d…
Finding Optimal Pathways in Chemical Reaction Networks Using Ising Machines
Yuta Mizuno, Tamiki Komatsuzaki
Finding optimal pathways in chemical reaction networks is essential for elucidating and designing chemical processes, with significant applications such as synthesis planning and m…
Gaussian Process Classification Bandits
Tatsuya Hayashi, Naoki Ito, Koji Tabata +4
Classification bandits are multi-armed bandit problems whose task is to classify a given set of arms into either positive or negative class depending on whether the rate of the arm…
Transfer entropy dependent on distance among agents in quantifying leader-follower relationships
Udoy S. Basak, Sulimon Sattari, Md. Motaleb Hossain +2
Synchronized movement of (both unicellular and multicellular) systems can be observed almost everywhere. Understanding of how organisms are regulated to synchronized behavior is on…
A Note on Enumeration by Fair Sampling
Yuta Mizuno, Tamiki Komatsuzaki
This note describes an algorithm for enumerating all the elements in a finite set based on uniformly random sampling from the set. This algorithm can be used for enumeration by fai…
Modes of Information Flow in Collective Cohesion
Sulimon Sattari, Udoy S. Basak, Ryan G. James +2
Pairwise interactions between individuals are taken as fundamental drivers of collective behavior responsible for group cohesion and decision-making. While an individual directly i…
An information-theoretic approach to infer the underlying interaction domain among elements from finite length trajectories in a noisy environment
Udoy S. Basak, Sulimon Sattari, Hossain M. Motaleb +2
Transfer entropy in information theory was recently demonstrated [Phys. Rev. E 102, 012404 (2020)] to enable us to elucidate the interaction domain among interacting elements solel…
Minor-embedding heuristics for large-scale annealing processors with sparse hardware graphs of up to 102,400 nodes
Yuya Sugie, Yuki Yoshida, Normann Mertig +7
Minor embedding heuristics have become an indispensable tool for compiling problems in quadratically unconstrained binary optimization (QUBO) into the hardware graphs of quantum an…
Beyond the Nucleus: Cytoplasmic Dominance in Follicular Thyroid Carcinoma Detection Using Single-Cell Raman Imaging Across Multiple Devices
Aurelien Pelissier, Kosuke Hashimoto, Kentaro Mochizuki +6
Cytological diagnosis of follicular thyroid carcinoma (FTC) is one of major challenges in the field of endocrine oncology due to absence of evident morphological indicators. Morpho…
A Bad Arm Existence Checking Problem
Koji Tabata, Atsuyoshi Nakamura, Junya Honda +1
We study a bad arm existing checking problem in which a player's task is to judge whether a positive arm exists or not among given K arms by drawing as small number of arms as poss…
Theory of Gas Phase Scattering and Reactivity for Astrochemistry
Laurent Wiesenfeld, Wing-Fai Thi, Paola Caselli +13
Because of the very peculiar conditions of chemistry in many astrophysical gases (low densities, mostly low temperatures, kinetics-dominated chemical evolution), great efforts have…
Single Molecule Data Analysis: An Introduction
Meysam Tavakoli, J. Nicholas Taylor, Chun-Biu Li +2
We review methods of data analysis for biophysical data with a special emphasis on single molecule applications. Our review is intended for anyone, from student to established rese…
Reactivity Boundaries to Separate the Fate of a Chemical Reaction Associated with Multiple Saddles
Yutaka Nagahata, Hiroshi Teramoto, Chun-Biu Li +2
Reactivity boundaries that divide the origin and destination of trajectories are crucial of importance to reveal the mechanism of reactions, which was recently found to exist robus…
Reactivity Boundaries to Separate the Fate of a Chemical Reaction Associated with an Index-two saddle
