• SmB6 dielectric response at low temperatures reveals crucial role of surface in impedance spectra. Equivalent inductance drops drastically as bulk starts to control conductivity micro-crystals are excellent candidates for tunable oscillators. We report results from an in–plane and out–of–plane study on SmB 6 single crystals, performed over a wide frequency range. A universal equivalent circui...

a number of innocent rashes occurs in neonates. they are usually transient and self limited and thus require no therapy but early recognition is important to distinguish these lesions from more serious disorders. in this study, our purpose was to determine the frequency of birthmarks in iranian neonates. the presence of various types of birthmarks was determined in 503 iranian neonates under 72...
