Beyond similarity assessment: Selecting the optimal model for sequence alignment via the Factorized Asymptotic Bayesian algorithm
Taikai Takeda, Michiaki Hamada
Pair Hidden Markov Models (PHMMs) are probabilistic models used for pairwise sequence alignment, a quintessential problem in bioinformatics. PHMMs include three types of hidden sta…
Multiscale enhanced path sampling based on the Onsager-Machlup action: Application to a model polymer
Hiroshi Fujisaki, Motoyuki Shiga, Kei Moritsugu +1
We propose a novel path sampling method based on the Onsager-Machlup (OM) action by generalizing the multiscale enhanced sampling (MSES) technique suggested by Moritsugu and cowork…
Onsager-Machlup action-based path sampling and its combination with replica exchange for diffusive and multiple pathways
Hiroshi Fujisaki, Motoyuki Shiga, Akinori Kidera
For sampling multiple pathways in a rugged energy landscape, we propose a novel action-based path sampling method using the Onsager-Machlup action functional. Inspired by the Fouri…
Triviality of hierarchical O(N) spin model in four dimensions with large N
Hiroshi Watanabe
The renormalization group transformation for the hierarchical O(N) spin model in four dimensions is studied by means of characteristic functions of single-site measures, and conver…
Mathematical Derivation of Chiral Anomaly in Lattice Gauge Theory with Wilson's Action
Tetsuya Hattori, Hiroshi Watanabe
Chiral U(1) anomaly is derived with mathematical rigor for a Euclidean fermion coupled to a smooth external U(1) gauge field on an even dimensional torus as a continuum limit of la…
Restoration of isotropy on fractals
Martin T. Barlow, Kumiko Hattori, Tetsuya Hattori +1
We report a new type of restoration of macroscopic isotropy (homogenization) in fractals with microscopic anisotropy. The phenomenon is observed in various physical setups, includi…
