Electromagnetic response of dense quark matter around color-superconducting phase transition and QCD critical point Open
We explore how the electric conductivity and associated relaxation time are modified near the QCD critical point and the phase transition to a color superconducting phase using the two-flavor Nambu-Jona-Lasinio model with finite current qu…

Estimation of electric field in intermediate-energy heavy-ion collisions Open
We estimate the spacetime profile of the electric field in head-on heavy-ion collisions at intermediate collision energies $\sqrt{s_{\rm NN}} = {\mathcal O}(3 \;-\; 10\;{\rm GeV})$. Using a hadronic cascade model (JAM; Jet AA Microscopic t…

Enhanced Dilepton production near the color superconducting phase and the QCD critical point Open
The dilepton production yields in relativistic heavy ion collisions are investigated along isentropic trajectories in the quark (Wigner) phase within the two-flavor Nambu-Jona-Lasinio model. An enhancement of the ultra-low energy dilepton …

Enhancement of dilepton production rate and electric conductivity around the QCD critical point Open
We investigate whether the soft mode that becomes massless at the QCD critical point (CP) causes an enhancement of the dilepton production rate (DPR) and electric conductivity around the CP through modification of the photon self-energy us…

ADAD2 functions in spermiogenesis and piRNA biogenesis in mice Open
Spermatogenesis is a continual process throughout the adult life of a male, which is governed by unique transcriptional regulation and massive alterations of chromatin. Histone modification was one of the underlying epigenetic mechanisms d…

ADAD2 functions in spermiogenesis and piRNA biogenesis in mice Open
Background Adenosine deaminase domain containing 2 (ADAD2) is a testis‐specific protein composed of a double‐stranded RNA binding domain and a non‐catalytic adenosine deaminase domain. A recent study showed that ADAD2 is indispensable for …

Relationship between PIWIL4-Mediated H3K4me2 Demethylation and piRNA-Dependent DNA Methylation Open
Retrotransposon genes are silenced by DNA methylation because of potential harm due to insertional mutagenesis. DNA methylation of retrotransposon genes is erased and re-established during male germ cell development. Both piRNA-dependent a…
