On finite analogues of Euler's constant

We introduce and study finite analogues of Euler's constant in the same setting as finite multiple zeta values. We define a couple of candidate values from the perspectives of a ``regularized value of $\zeta(1)$'' and of Mascheroni's and Kluyver--N\"orlund's series expressions of Euler's constant using Gregory coefficients. Moreover, we reveal that the differences between them always lie in the $\mathbb{Q}$-vector space spanned by 1 and values of a finite analogue of logarithm at positive integers.Comment: 14 page

Towards the Deep Riemann Hypothesis for GLn\mathrm{GL}_{n}

We explicate the deep Riemann hypothesis for the general linear group $\mathrm{GL}_{n}$ on the convergence of normalised Euler products of standard $L$-functions on the critical line. It conditionally improves upon the error term in the prime number theorem beyond what the grand Riemann hypothesis predicts. Furthermore, we discuss the Chebyshev bias for Satake parameters on $\mathrm{GL}_{n}$ from the perspective of the deep Riemann hypothesis.Comment: 17 page

Kampo, a Traditional Japanese Medicine, for the Body, Mind, and Soul

Traditional Japanese (Kampo) medicine is widely used to treat numerous conditions. Kampo medicine includes herbal formulas, acupuncture, moxibustion, and massage. After the Great East Japan Earthquake (GEJE), Kampo medicine was used to treat the imbalances in the body, mind, and soul in severely affected areas. The effects of the Kampo medicine saikokeishikankyoto (SKK) for the treatment of post-traumatic stress disorder (PTSD) have been proven in our clinical study. In this chapter, we have summarized both our reports from the Kampo medical clinics that were set up after the GEJE disaster and our findings of the clinical study on PTSD treatment in disaster survivors

Charged particle display

An optical shutter based on charged particles is presented. The output light intensity of the proposed device has an intrinsic dependence on the interparticle spacing between charged particles, which can be controlled by varying voltages applied to the control electrodes. The interparticle spacing between charged particles can be varied continuously and this opens up the possibility of particle based displays with continuous grayscale.Comment: typographic errors corrected in Eqs (37) and (39); published in Journal of Applied Physics; doi:10.1063/1.317648

Evolution of network structure by temporal learning

We study the effect of learning dynamics on network topology. A network of discrete dynamical systems is considered for this purpose and the coupling strengths are made to evolve according to a temporal learning rule that is based on the paradigm of spike-time-dependent plasticity. This incorporates necessary competition between different edges. The final network we obtain is robust and has a broad degree distribution.Comment: revised manuscript in communicatio

In the case of the effect of "Shall we look on your character?" of Kan‒Dai 1 seminar

The purpose of this survey is to evaluate the educational effects of a delivery lecture on character analysis for high school students. People are now clamoring about the need for career counseling adapted to the times. The effect of the egogram carried out for high school students as part of career counseling was checked from their comment. Based on this consideration the importance of various types of career counseling for the young people is argued

Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting

In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction. Here we investigate the 3-dimensional (3D) bulk band structures of BiTeI using the bulk-sensitive $h\nu$-dependent soft x-ray angle resolved photoemission spectroscopy (SX-ARPES). The obtained band structure is shown to be well reproducible by the first-principles calculations, with huge spin splittings of ${\sim}300$ meV at the conduction-band-minimum and valence-band-maximum located in the $k_z=\pi/c$ plane. It provides the first direct experimental evidence of the 3D Rashba-type spin splitting in a bulk compound.Comment: 9 pages, 4 figure
