Observation of PeV Gamma Rays from the Monogem Ring with the Tibet Air Shower Array
The Tibet AS Gamma Collaboration, M. Amenomori
We searched for steady PeV gamma-ray emission from the Monogem ring region with the Tibet air shower array from 1997 February to 2004 October. No evidence for statistically signifi…
Are protons still dominant at the knee of the cosmic-ray energy spectrum?
The Tibet AS Gamma Collaboration, M. Amenomori
A hybrid experiment consisting of emulsion chambers, burst detectors and the Tibet II air-shower array was carried out at Yangbajing (4,300 m a.s.l., 606 g/cm) in Tibet to obta…
Multifractal PDF analysis for intermittent systems
T. Arimitsu, N. Arimitsu
The formula for probability density functions (PDFs) has been extended to include PDF for energy dissipation rates in addition to other PDFs such as for velocity fluctuations, velo…
Magnetization Losses in Multiply Connected YBa2Cu3O6+x Coated Conductors
G. A. Levin, P. N. Barnes, Naoyuki Amemiya +4
We report the results of a magnetization losses study in experimental multifilament, multiply connected coated superconductors exposed to time-varying magnetic field. In these samp…
Quantum Nernst Effect
Hiroaki Nakamura, Naomichi Hatano, Ryoen Shirasaki
We report our recent predictions on the quantum Nernst effect, a novel thermomagnetic effect in the quantum Hall regime. We assume that, when the chemical potential is located betw…
Food Webs: Experts Consuming Families of Experts
A. G. Rossberg, H. Matsuda, T. Amemiya +1
The question what determines the structure of natural food webs has been listed among the nine most important unanswered questions in ecology. It arises naturally from many problem…
