Measurement-Based Quantum Computation on Symmetry Breaking Thermal States
We consider measurement-based quantum computation (MBQC) on thermal states of
the interacting cluster Hamiltonian containing interactions between the cluster
stabilizers that undergoes thermal phase transitions. We show that the
long-range order of the symmetry breaking thermal states below a critical
temperature drastically enhance the robustness of MBQC against thermal
excitations. Specifically, we show the enhancement in two-dimensional cases and
prove that MBQC is topologically protected below the critical temperature in
three-dimensional cases. The interacting cluster Hamiltonian allows us to
perform MBQC even at a temperature an order of magnitude higher than that of
the free cluster Hamiltonian.Comment: 8 pages, 7 figure
Bright Type II SN 2023ixf in M101: A Quick Analysis of the Early-Stage Spectroscopic and Near-Infrared Light Curves
We present the early-stage analysis of the low-resolution () optical
spectra and the near-infrared light curves of the bright Type II supernova (SN
II) 2023ixf in the notable nearby face-on spiral galaxy M101, which are
obtained since until d. Our first spectrum shows remarkable
emission features of Balmer series, He~{\sc ii}, N~{\sc iv}, and C~{\sc iv}
with a strong blue continuum. Compared with SNe II showing the flash-ionized
features, we suggest that this SN could be categorized into high-luminosity SNe
II with a nitrogen/helium-rich circumstellar material (CSM), e.g., SNe 2014G,
2017ahn, and 2020pni. The H~{} emission line is composed of broad
(~2800 km~s), intermediate (520 km~s), and narrow (
km~s) components. The near-infrared light curves are well consistent
with those of another luminous SN II 2017ahn, and the absolute magnitudes
locate on the bright end in the lumosity distribution of SNe II. These
observational facts support that SN 2023ixf is well consistent with a
high-luminosity SN II with the dense nitrogen/helium-rich CSM.Comment: 5 pages, 4 figures, submitted to PASJ Letter

EFFECTS OF COMBINATIONS OF PATTERNMAKING METHODS AND DRESS FORMS ON GARMENT APPEARANCE
We investigated the effects of the combinations of patternmaking methods and dress forms on the appearance of a garment. Six upper garments were made using three patternmaking methods used in France, Italy, and Japan, and two dress forms made in Japan and France. The patterns and the appearances of the garments were compared using geometrical measurements. Sensory evaluations of the differences in garment appearance and fit on each dress form were also carried out. In the patterns, the positions of bust and waist darts were different. The waist dart length, bust dart length, and positions of the bust top were different depending on the patternmaking method, even when the same dress form was used. This was a result of differences in the measurements used and the calculation methods employed for other dimensions. This was because the ideal body shape was different for each patternmaking method. Even for garments produced for the same dress form, the appearances of the shoulder, bust, and waist from the front, side, and back views were different depending on the patternmaking method. As a result of the sensory evaluation, it was also found that the bust and waist shapes of the garments were different depending on the combination of patternmaking method and dress form. Therefore, to obtain a garment with better appearance, it is necessary to understand the effects of the combinations of patternmaking methods and body shapes.ArticleAUTEX RESEARCH JOURNAL.17(3):277-286(2017)journal articl

Use of Nucleic Acid Analogs for the Study of Nucleic Acid Interactions
Unnatural nucleosides have been explored to expand the properties and the applications of oligonucleotides. This paper briefly summarizes nucleic acid analogs in which the base is modified or replaced by an unnatural stacking group for the study of nucleic acid interactions. We also describe the nucleoside analogs of a base pair-mimic structure that we have examined. Although the base pair-mimic nucleosides possess a simplified stacking moiety of a phenyl or naphthyl group, they can be used as a structural analog of Watson-Crick base pairs. Remarkably, they can adopt two different conformations responding to their interaction energies, and one of them is the stacking conformation of the nonpolar aromatic group causing the site-selective flipping of the opposite base in a DNA double helix. The base pair-mimic nucleosides can be used to study the mechanism responsible for the base stacking and the flipping of bases out of a nucleic acid duplex
