    Kondo screening in a Majorana metal

    Kondo impurities provide a nontrivial probe to unravel the character of the excitations of a quantum spin liquid. In the S = 1/2 Kitaev model on the honeycomb lattice, Kondo impurities embedded in the spin-liquid...

    The influence of preoperative epidural labor analgesia on postoperative pain in parturients undergoing emergency cesarean section

    Intense noxious input from the periphery may result in central sensitization and hyperexcitability, thus accentuating subsequent postoperative pain. Parturients who undergo emergency cesarean section (C-sec) a...

    Ultrasonographic investigation of the effect of positive end-expiratory pressure on the cross-sectional area of the femoral vein

    Femoral veins are commonly used as a relatively safe alternative route for central venous cannulation. Several maneuvers are used to increase the cross-sectional area of the vein. In this study, we assessed th...
