From the multi-terms urn model to the self-exciting negative binomial distribution and Hawkes processes
Masato Hisakado, Kodai Hattori, Shintaro Mori
This study considers a new multi-term urn process that has a correlation in the same term and temporal correlation. The objective is to clarify the relationship between the urn mod…
Jets from MRC 0600-399 bent by magnetic fields in the cluster Abell 3376
James O. Chibueze, Haruka Sakemi, Takumi Ohmura +7
Galaxy clusters are known to harbour magnetic fields. The nature of the intra-cluster magnetic fields remains an unresolved question. Intra-cluster magnetic field can be observed a…
Pólya urn with memory kernel and asymptotic behaviours of autocorrelation function
Shintaro Mori, Masato Hisakado, Kazuaki Nakayama
Pólya urn is a stochastic process in which balls are randomly drawn from an urn of red and blue balls, and balls of the same color as the drawn balls are added. The probability of…
Magnetic Switching by Oxygen Adsorption in Metal-Organic Framework Systems
Masaki Kato, Kunio Tokushuku, Hiroyasu Matsuura +2
In this letter, we address magnetization switching by oxygen adsorption in porous metal-organic framework systems. To this end, we construct a simple localized spin model combined…
No-Transaction Band Network: A Neural Network Architecture for Efficient Deep Hedging
Shota Imaki, Kentaro Imajo, Katsuya Ito +2
Deep hedging (Buehler et al. 2019) is a versatile framework to compute the optimal hedging strategy of derivatives in incomplete markets. However, this optimal strategy is hard to…
