Radiation-Induced Degradation Mechanism of X-ray SOI Pixel Sensors with Pinned Depleted Diode Structure
Kouichi Hagino, Masatoshi Kitajima, Takayoshi Kohmura +7
The X-ray Silicon-On-Insulator (SOI) pixel sensor named XRPIX has been developed for the future X-ray astronomical satellite FORCE. XRPIX is capable of a wide-band X-ray imaging sp…
Usefulness of Instructor Annotations on Flipped Learning Preparation Video System
Shintaro Uchiyama, Hayato Okumoto, Mitsuo Yoshida +2
Flipped learning is a method that flips in/out class activities to make lectures learner-centered. In flipped learning, comments from learners on preparation material are useful in…
Influence of EOS on compact star made of hidden sector nucleons
Shinji Maedan
We study compact star made of degenerate hidden sector nucleons which will be a candidate for cold dark matter. A hidden sector like QCD is considered, and as the low energy effect…
Response Collector: A Video Learning System for Flipped Classrooms
Hayato Okumoto, Mitsuo Yoshida, Kyoji Umemura +1
The flipped classroom has become famous as an effective educational method that flips the purpose of classroom study and homework. In this paper, we propose a video learning system…
Sublinear decoding schemes for non-adaptive group testing with inhibitors
Thach V. Bui, Minoru Kuribayashi, Tetsuya Kojima +1
Identification of up to defective items and up to inhibitors in a set of items is the main task of non-adaptive group testing with inhibitors. To efficiently reduce the…
Efficient (nonrandom) construction and decoding for non-adaptive group testing
Thach V. Bui, Minoru Kuribayashi, Tetsuya Kojima +2
The task of non-adaptive group testing is to identify up to defective items from items, where a test is positive if it contains at least one defective item, and negative ot…
Informational Theory of Relativity
Akio Hosoya, Shunsuke Fujii
Assuming the minimal time to send a bit of information in the Einstein clock synchronization of the two clocks located at different positions, we introduce the extended metric to t…
Occurrence of Fermi Pockets without Pseudogap Hypothesis and Clarification of the Energy Distribution Curves of Angle-Resolved Photoemission Spectroscopy in Underdoped Cuprate Superconductors
Hiroshi Kamimura, Kenji Sasaoka, Hideki Ushio
Central issues in the electronic structure of underdoped cuprate superconductors are to clarify the shape of the Fermi surfaces and the origin of the pseudogap. On the basis of the…
Influence of current mass on the spatially inhomogeneous chiral condensate
Shinji Maedan
It is known that, in the chiral limit, spatially inhomogeneous chiral condensate occurs in the Nambu-Jona-Lasinio (NJL) model at finite density within a mean-field approximation. W…
Light Mesons on the Light Front
K. Naito, S. Maedan, K. Itakura
We study the properties of light mesons in the scalar, pseudo-scalar, and vector channels within the light-front quantization, by using the (one flavor) Nambu--Jona-Lasinio model w…
Vector Mesons on the Light Front
K. Naito, S. Maedan, K. Itakura
We apply the light-front quantization to the Nambu--Jona-Lasinio model with the vector interaction, and compute vector meson's mass and light-cone wavefunction in the large N limit…
Quantum description for a chiral condensate disoriented in a certain direction in isospace
S. Maedan
We derive a quantum state of the disoriented chiral condensate dynamically, considering small quantum fluctuations around a classical chiral condensate disoriented in a certain dir…
How parametric resonance mechanism follows quench mechanism in disoriented chiral condensate
S. Maedan
We show how parametric resonance mechanism follows quench mechanism in the classical linear sigma model. The parametric resonance amplifies long wavelength modes of the pion for mo…
Light-Front Realization of Chiral Symmetry Breaking
K. Itakura, S. Maedan
We discuss a description of chiral symmetry breaking in the light-front (LF) formalism. Based on careful analyses of several models, we give clear answers to the following three fu…
Dynamical Chiral Symmetry Breaking on the Light Front I. DLCQ Approach
K. Itakura, S. Maedan
Dynamical chiral symmetry breaking in the DLCQ method is investigated in detail using a chiral Yukawa model closely related to the Nambu-Jona-Lasinio model. By classically solving…
Infrared divergence on the light-front and dynamical Higgs mechanism
S. Maedan
Dynamical Higgs mechanism on the light-front (LF) is studied using a (1+1) dimensional model, with emphasis on the infrared divergence problem. The consideration of the zero mode $…
Classical Aspects of the Abelian Higgs Model on the Light Front
K. Itakura, S. Maedan, M. Tachibana
We investigate canonical structure of the Abelian Higgs model within the framework of DLCQ. Careful boundary analysis of differential equations, such as the Euler-Lagrange equation…
