H3K36 Trimethylation-Mediated Epigenetic Regulation is Activated by Bam and Promotes Germ Cell Differentiation During Early Oogenesis in Drosophila
Autor: Masanori Mukai, Seiji Hira, Katsuhiro Nakamura, Shoichi Nakamura, Hiroshi Kimura, Masanao Sato, Satoru Kobayashi
Publikováno v: Biology Open, Vol 4, Iss 2, Pp 119-124 (2015)
Epigenetic silencing is critical for maintaining germline stem cells in Drosophila ovaries. However, it remains unclear how the differentiation factor, Bag-of-marbles (Bam), counteracts transcriptional silencing. We found that the trimethylation of l

Fast-forward scaling theory for phase imprinting on a BEC: creation of a wave packet with uniform momentum density and loading to Bloch states without disturbance
Autor: Shumpei Masuda, Katsuhiro Nakamura, Mikio Nakahara
Publikováno v: New Journal of Physics, Vol 20, Iss 2, p 025008 (2018)
We study phase imprinting on Bose–Einstein condensates (BECs) with the fast-forward scaling theory revealing a nontrivial scaling property in quantum dynamics. We introduce a wave packet with uniform momentum density (WPUM) which has peculiar prope

Pilot test of study on brine injection into shallow formation for mitigating land subsidence in the Southern Kanto Gas Field in Japan
Autor: Nobuhiro Ono, Tsutomu Nakagawa, Katsuhiro Nakamura, Akira Kurihara, Toshiaki Yamaguchi, Yuji Hayashi, Kazunori Ono, Shota Kuroshima, Noriyuki Muraoka
Publikováno v: Proceedings of the International Association of Hydrological Sciences, Vol 382, Pp 787-790 (2020)
In the Southern Kanto Gas Field, natural gas dissolved in water has been produced for over 80 years. In order to produce the natural gas dissolved in water, formation water must be pumped from a reservoir in the gas field. The production of formation

Fast forward approach to stochastic heat engine
Autor: Yuki Izumida, Katsuhiro Nakamura, Jasur Matrasulov
The fast-forward (FF) scheme proposed by Masuda and Nakamura (\textit{Proc. R. Soc. A} \textbf{466}, 1135 (2010)) in the context of conservative quantum dynamics can reproduce a quasi-static dynamics in an arbitrarily short time. We apply the FF sche

Publikováno v: T. Mito et al., "Reexamination of Refrigeration Power of the LHD Cryogenic System After Fire and Restart of Operation," in IEEE Transactions on Applied Superconductivity, vol. 28, no. 4, pp. 1-4, June 2018, Art no. 4206004, doi: 10.1109/TASC.2018.2810517.
The Large Helical Device (LHD), built in the 1990s, is a heliotron-type fusion plasma experimental device with the world's first fully superconducting magnetic confinement system. The LHD cryogenic system operated stably for 18 years from 1998 to 201

Fast-forward approach to adiabatic quantum dynamics of regular spin clusters: nature of geometry-dependent driving interactions
Autor: Iwan Setiawan, S. Avazbaev, Katsuhiro Nakamura, Bobby E. Gunara
The fast forward scheme of adiabatic quantum dynamics is applied to finite regular spin clusters with various geometries and the nature of driving interactions is elucidated. The fast forward is the quasi-adiabatic dynamics guaranteed by regularizati

Quantum gas in the fast forward scheme of adiabatically expanding cavities: Force and equation of states
Autor: Gulmira Babajanova, Katsuhiro Nakamura, Jasur Matrasulov
With use of the scheme of fast forward which realizes quasi-static or adiabatic dynamics in shortened time scale, we investigate a thermally-isolated ideal quantum gas confined in a rapidly dilating one-dimensional (1D) cavity with the time-dependent
