Deviations from Tri-Bimaximality and Quark-Lepton Complementarity
We study deviations from tri-bimaximality (TBM) and quark-lepton
complementarity (QLC) in a model independent way. The current neutrino
experimental data is well approximated by tri-bimaximal generation mixing but
the QLC relations are not satisfied with each data of 1 level. This
means that there exist deviations from the complementarity. The same fact for
the TBM might be checked in the future neutrino experiments. We discuss such
deviations from the TBM and QLC, simultaneously. A new ratio between the
deviations is introduced, and some interesting points are presented. We also
show predicted correlations among leptonic mixing angles at the points.Comment: 10 pages, 9 figures, final versio
Search for new physics via photon polarization of
We suggest a discriminant analysis of new physics beyond the standard model
through a detection of photon polarization in a radiative B meson decay. This
analysis is investigated in SUSY SU(5) GUT with right-handed neutrino and
left-right symmetric models. New physics search via CP asymmetry in the same
process are also evaluated in each model for comparison. We show that new
physics can be found via detecting the photon polarization in a parameter space
of TeV energy scale.Comment: 20 pages, 8 figures, v2:references added, v3:published versio

Oxy-trifluoromethylation of alkenes and its application to the synthesis of β-trifluoromethylstyrene derivatives
AbstractOxy-trifluoromethylation of di-substituted styrenes and dienes was achieved by using Cu/Togni's reagent system. Not only gem-di-substituted styrenes, but also a β-methylstyrene derivative were transformed to the corresponding oxy-trifluoromethylation products. 1,4-Addition products were obtained selectively in the reaction of mono-substituted dienes. These reactions provide a new approach for the synthesis of β-trifluoromethyl styrene derivatives
Deep Selection: A Fully Supervised Camera Selection Network for Surgery Recordings
Recording surgery in operating rooms is an essential task for education and
evaluation of medical treatment. However, recording the desired targets, such
as the surgery field, surgical tools, or doctor's hands, is difficult because
the targets are heavily occluded during surgery. We use a recording system in
which multiple cameras are embedded in the surgical lamp, and we assume that at
least one camera is recording the target without occlusion at any given time.
As the embedded cameras obtain multiple video sequences, we address the task of
selecting the camera with the best view of the surgery. Unlike the conventional
method, which selects the camera based on the area size of the surgery field,
we propose a deep neural network that predicts the camera selection probability
from multiple video sequences by learning the supervision of the expert
annotation. We created a dataset in which six different types of plastic
surgery are recorded, and we provided the annotation of camera switching. Our
experiments show that our approach successfully switched between cameras and
outperformed three baseline methods.Comment: MICCAI 202
Consecutive ruptures on a complex conjugate fault system during the 2018 Gulf of Alaska earthquake
2018年アラスカ湾地震の複雑な破壊過程を解析 --間欠的に加速・減速する奇妙な巨大地震--. 京都大学プレスリリース. 2021-03-22.We developed a flexible finite-fault inversion method for teleseismic P waveforms to obtain a detailed rupture process of a complex multiple-fault earthquake. We estimate the distribution of potency-rate density tensors on an assumed model plane to clarify rupture evolution processes, including variations of fault geometry. We applied our method to the 23 January 2018 Gulf of Alaska earthquake by representing slip on a projected horizontal model plane at a depth of 33.6 km to fit the distribution of aftershocks occurring within one week of the mainshock. The obtained source model, which successfully explained the complex teleseismic P waveforms, shows that the 2018 earthquake ruptured a conjugate system of N-S and E-W faults. The spatiotemporal rupture evolution indicates irregular rupture behavior involving a multiple-shock sequence, which is likely associated with discontinuities in the fault geometry that originated from E-W sea-floor fracture zones and N-S plate-bending faults
