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

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

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 $T_A$

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

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

In the complex action theory whose path runs over not only past but also future we study a normalized matrix element of an operator $\hat{\cal O}$ defined in terms of the future state at the latest time $T_B$ and the past state at the earliest time $
