Automatic hermiticity for mixed states
Autor: Keiichi Nagao, Holger Bech Nielsen
Publikováno v: Progress of Theoretical and Experimental Physics
Nagao, K & Nielsen, H B 2023, ' Automatic hermiticity for mixed states ', Progress of Theoretical and Experimental Physics, vol. 2023, no. 3, 031B01 . https://doi.org/10.1093/ptep/ptad025
We previously proposed a mechanism to effectively obtain, after a long time development, a Hamiltonian being Hermitian with regard to a modified inner product $I_Q$ that makes a given non-normal Hamiltonian normal by using an appropriately chosen Her

Formalism of a harmonic oscillator in the future-included complex action theory
Autor: Holger Bech Nielsen, Keiichi Nagao
Publikováno v: Nagao, K & Nielsen, H B 2019, ' Formalism of a harmonic oscillator in the future-included complex action theory ', Progress of Theoretical and Experimental Physics, vol. 2019, no. 7, 073B01 . https://doi.org/10.1093/ptep/ptz047
In a special representation of complex action theory that we call ``future-included'', we study a harmonic oscillator model defined with a non-normal Hamiltonian $\hat{H}$, in which a mass $m$ and an angular frequency $\omega$ are taken to be complex

Complex action suggests future-included theory
Autor: Keiichi Nagao, Holger Bech Nielsen
Publikováno v: Nagao, K & Nielsen, H B 2017, ' Complex action suggests future-included theory ', Progress of Theoretical and Experimental Physics, vol. 2017, no. 11, 111B01 . https://doi.org/10.1093/ptep/ptx156
In quantum theory its action is usually taken to be real, but we can consider another theory whose action is complex. In addition, in the Feynman path integral, the time integration is usually performed over the period between the initial time $T_A$

Reality from maximizing overlap in the future-included real action theory
Autor: Holger Bech Nielsen, Keiichi Nagao
Publikováno v: Progress of Theoretical and Experimental Physics. 2017
In the future-included real action theory whose path runs over not only past but also future, we demonstrate a theorem, which states that the normalized matrix element of a Hermitian operator $\hat{\cal O}$ defined in terms of the future state at the

Erratum to: 'Vortex fermion on the lattice' [Nucl. Phys. B 636 (2002) 264–290]
Autor: Keiichi Nagao
Publikováno v: Nuclear Physics B. 800:401-404
In Ref. [H. Neuberger, hep-lat/03030090 ] Neuberger studied a vortex fermion model with two continuum extra-dimensions, and pointed out that there are no k ≠ 0 zero modes, which is in disagreement with our paper. Since this discrepancy is due to an

Even with the standard first-line chemotherapy, advanced non-small cell lung cancer (NSCLC) recurs in most cases. The purpose of this study is to develop a new chemotherapeutic regimen for patients with NSCLC that has relapsed or was refractory to pr

State of hepatitis C viral replication enhances activation of NF-kB- and AP-1-signaling induced by hepatitis B virus X
Autor: Keiichi Nagao, Hiromitsu Saisho, Tatsuo Kanda, Osamu Yokosuka

We examined the effect of hepatitis B virus X (HBx) on NF-kB- and AP-1- mediated transcription in human hepatocellular carcinoma cell lines, Huh-7 with or without subgenomic hepatitis C virus (HCV) RNA. Expression of HBx in Huh-7 cells with HCV resul

Publikováno v: Biochemical and Biophysical Research Communications. 331:621-629
The effect of six drugs (amantadine, glycyrrhizin, ribavirin, ursodeoxycholic acid, alcohol, and IFN) on HAV RNA translation from the HAV internal ribosomal entry site (IRES) was investigated using a bicistronic reporter construct containing HAV IRES
