    DNA barcoding and gene expression recording reveal the presence of cancer cells with unique properties during tumor progression

    Tumors comprise diverse cancer cell populations with specific capabilities for adaptation to the tumor microenvironment, resistance to anticancer treatments, and metastatic dissemination. However, whether thes...

    Holographic entanglement and causal shadow in time-dependent Janus black hole

    We holographically compute an inter-boundary entanglement entropy in a time-dependent two-sided black hole which was constructed in [1] by applying time-dependent Janus deformation to BTZ black hole. The black...

    Holographic heavy quark symmetry

    We investigate the heavy quark spin symmetry, i.e. the mass degeneracy of pseudo-scalar and vector quarkonia at heavy quark limit, by using the gauge/gravity correspondence. We allow generic D3-like geometry w...

    Soliton stars as holographic confined Fermi liquids

    In this paper, we study a holographic dual of a confined Fermi liquid state by putting a charged fluid of fermions in the AdS soliton geometry. This can be regarded as a confined analogue of electron stars. De...

    Holographic Fermi surfaces and entanglement entropy

    We argue that Landau-Fermi liquids do not have any gravity duals in the purely classical limit. We employ the logarithmic behavior of entanglement entropy to characterize the existence of Fermi surfaces. By im...

    Higher derivative corrections to holographic entanglement entropy for AdS solitons

    We investigate the behaviors of holographic entanglement entropy for AdS soliton geometries in the presence of higher derivative corrections. We calculate the leading higher derivative corrections for the AdS5 se...

    On non-chiral extension of Kerr/CFT

    We discuss possible non-chiral extension of the Kerr/CFT correspondence. We first consider the near horizon geometry of an extremal BTZ black hole and study the asymptotic symmetry. In order to define it prope...

    Emergent AdS3 in the zero entropy extremal black holes

    We investigate the zero entropy limit of the near horizon geometries of D = 4 and D = 5 general extremal black holes with $ {\text{SL}...

    New catalytic functions of Pd–Zn, Pd–Ga, Pd–In, Pt–Zn, Pt–Ga and Pt–In alloys in the conversions of methanol

    Pd and Pt supported on ZnO, Ga2O3 and In2O3 exhibit high catalytic performance for the steam reforming of methanol, CH3OH+H2O→CO2+3HH2, and the dehydrogenation of methanol to HCOOCH3, 2CH3OH→HCOOCH3+2HH2. Combine...
