Memory effect of external oscillation on residual stress in a paste
Jumpei Morita, Michio Otsuki
We numerically investigate the stress distribution of a paste when an external oscillation is applied. The paste memorizes the oscillation as plastic deformation. Due to the plasti…
Analytical and numerical solutions to ergodic control problems arising in environmental management
Hidekazu Yoshioka, Motoh Tsujimura, Yuta Yaegashi
Environmental management optimizing a long-run objective is an ergodic control problem whose resolution can be achieved by solving an associated non-local Hamilton-Jacobi-Bellman (…
Classification of generalized Yamabe solitons in Euclidean spaces
Shunya Fujii, Shun Maeta
In this paper, we consider generalized Yamabe solitons which include many notions, such as Yamabe solitons, almost Yamabe solitons, h-almost Yamabe solitons, gradient k-Yamabe soli…
HJB and Fokker-Planck equations for river environmental management based on stochastic impulse control with discrete and random observation
H. Yoshioka, M. Tsujimura, K. Hamagami +2
We formulate a new two-variable river environmental restoration problem based on jump stochastic differential equations (SDEs) governing the sediment storage and nuisance benthic a…
First principles study on the thermoelectric performance of CaAlSi-type Zintl phase compounds
Hidetomo Usui, Kazuhiko Kuroki
We investigate the thermoelectric properties of CaAlSi-type Zintl phase compounds ( = Mg, Ca, Sr, Ba, = Mg, Zn, Cd, and = P, As, Sb) using first princi…
Renormalizable GUT with Suppressed Dimension-5 Proton Decays
Naoyuki Haba, Yukihiro Mimura, Toshifumi Yamada
We study a renormalizable SUSY GUT model where the Yukawa couplings of single , single and single fields, $Y_{10},Y_{126},Y_{1…
Possible pairing mechanism switching driven by structural symmetry breaking in BiS2-based layered superconductors
Aichi Yamashita, Hidetomo Usui, Kazuhisa Hoshi +3
Investigation of isotope effects on superconducting transition temperature (Tc) is one of the useful methods to examine whether electron-phonon interaction is essential for pairing…
Theta-graph and diffeomorphisms of some 4-manifolds
Tadayuki Watanabe
In this article, we construct countably many mutually non-isotopic diffeomorphisms of some closed non simply-connected 4-manifolds that are homotopic to but not isotopic to the ide…
Charged Lepton Flavor Violating processes in Neutrinophilic Higgs+Seesaw model
Naoyuki Haba, Tsuneharu Omija, Toshifumi Yamada
We investigate charged lepton flavor violating (CFLV) processes in the `neutrinophilic Higgs+seesaw model', in which right-handed neutrinos couple only with an extra Higgs field wh…
QED and QCD helicity amplitudes in parton-shower gauge
Kaoru Hagiwara, Junichi Kanzaki, Kentarou Mawatari
We introduce photon and gluon propagators in which the scalar polarization component is subtracted systematically by making use of the BRST invariance of the off-shell vector boson…
Magnetoelectric Effect in the Antiferromagnetic Ordered State of CeTiBi with Ce Zig-Zag Chains
Masahiro Shinozaki, Gaku Motoyama, Masahiro Tsubouchi +8
In this study, we investigate the magnetoelectric (ME) effect of the newly discovered antiferromagnetic (AFM) compound CeTiBi with a hexagonal structure (space group $P…
Muon and Electron and the Origin of Fermion Mass Hierarchy
Naoyuki Haba, Yasuhiro Shimizu, Toshifumi Yamada
We present a model that gives a natural explanation to the charged lepton mass hierarchy and study the contributions to the electron and the muon . In the model, we introduce…
Electronic Structure of ( = 0.25, = 0.08) Revealed by Angle-Resolved Photoemission Spectroscopy
Toru Adachi, Shinichiro Ideta, Zi How Tin +4
We have investigated the electronic structure of ( = 0.25, = 0.08) by means o…
Regime-switching constrained viscosity solutions approach for controlling dam-reservoir systems
H. Yoshioka, Y. Yoshioka
A new stochastic control problem of a dam-reservoir system installed in a river is analyzed both mathematically and numerically. Water balance dynamics of the reservoir are piece-w…
