Quantifying Collective Emotions: Japan's Societal Trends Through Enhanced Sentiment Index Using POMS2 and SNS
Koutarou Tamura, Yukie Sano, Junichi Shiozaki
In this study, we constructed an emotion index that quantitatively represents the collective emotions present in the Japanese web space by utilizing Social Networking Service (SNS)…
Observation of phonon Poiseuille flow in isotopically-purified graphite ribbons
Xin Huang, Yangyu Guo, Yunhui Wu +7
In recent times, the unique collective transport physics of phonon hydrodynamics motivates theoreticians and experimentalists to explore it in micro- and nanoscale and at elevated…
RM-CVaR: Regularized Multiple -CVaR Portfolio
Kei Nakagawa, Shuhei Noma, Masaya Abe
The problem of finding the optimal portfolio for investors is called the portfolio optimization problem. Such problem mainly concerns the expectation and variability of return (i.e…
Bounds on Separating Redundancy of Linear Codes and Rates of X-Codes
Yu Tsunoda, Yuichiro Fujiwara, Hana Ando +1
An error-erasure channel is a simple noise model that introduces both errors and erasures. While the two types of errors can be corrected simultaneously with error-correcting codes…
Supersymmetry and d-Wave Superconductivity
Kazusumi Ino
Motivated by a recent development in the field theory of the fractional quantum Hall effect, we propose a supersymmetric field theoretical model of quantum critical d-wave and (d+i…
Field theory of spin-singlet quantum Hall states
Kazusumi Ino
We formulate a field theory for a class of spin-singlet quantum Hall states (the Haldane-Rezayi state and its variants) which have been proposed for the quantized Hall plateaus obs…
Persistent edge currents for paired quantum hall states
Kazusumi Ino
We study the behavior of the persistent edge current for paired quantum Hall states on the cylinder. We show that the currents are periodic with the unit flux . At low te…
Spin-singlet hierarchy in the fractional quantum Hall effect
Kazusumi Ino
We show that the so-called permanent quantum Hall states are formed by the integer quantum Hall effects on the Haldane-Rezayi quantum Hall state. Novel conformal field theory descr…
