The phases identified by WAXS include $\gamma$ (matrix), $\gamma$′ (hardening precipitates), MC (metallic carbides), and M$_{23}$C$_6$/M$_6$C (secondary metallic carbides) [...] Restricted: PDF PDF (PDFA); 2017-11-2009:47 [PUBDB-2017-12115] Journal Article et al Running of the charm-quark mass from HERA deep-inelastic scattering data Physics letters / B 775, 233 - 238 (2017) [10.1016/j.physletb.2017.11.002]   Combined HERA data on charm production in deep-inelastic scattering have previously been used to determine the charm-quark running mass $m_{c}(m_{c})$ in the $\overline{MS}$renormalisation scheme. Here, the same data are used as a function of the photon virtuality $Q^2$ to evaluate the charm-quark running mass at different scales to one-loop order, in the context of a next-to-leading order QCD analysis [...] OpenAccess: PDF PDF (PDFA); 2017-11-1623:55 [PUBDB-2017-12073] Journal Article et al Structural, magnetic and electronic properties of pulsed-laser-deposition grown SrFeO$_{3−δ}$ thin films and SrFeO$_{3−δ}$/La$_{2/3}$Ca$_{1/3}$MnO$_{3}$ multilayers Journal of physics / Condensed matter 29(49), 495601 (2017) [10.1088/1361-648X/aa93a6]   We studied the structural, magnetic and electronic properties of ${\rm SrFeO}_{3-\delta}$ (SFO) thin films and ${\rm SrFeO}_{3-\delta}$ /${\rm La}_{2/3}$ ${\rm Ca}_{1/3}$ MnO3 (LCMO) superlattices that have been grown with pulsed laser deposition (PLD) on ${\rm La}_{0.3}$ ${\rm Sr}_{0.7}$ ${\rm Al}_{0.65}$ ${\rm Ta}_{0.35}$ ${\rm O}_{3}$ (LSAT) substrates.

Time-resolved ultrafast x-ray scattering from an incoherent electronic mixture Physical review / A 96(5), 053413 (2017) [10.1103/PhysRevA.96.053413]   Time-resolved ultrafast x-ray scattering from photoexcited matter is an emerging method to image ultrafast dynamics in matter with atomic-scale spatial and temporal resolutions. For a correct and rigorous understanding of current and upcoming imaging experiments, we present the theory of time-resolved x-ray scattering from an incoherent electronic mixture using quantum electrodynamical theory of light-matter interaction [...] OpenAccess: PDF PDF (PDFA); 2017-11-1611:27 [PUBDB-2017-12039] Report/Journal Article et al Search for $\Lambda_c^+\to\phi p \pi^0$ and branching fraction measurement of $\Lambda_c^+\to K^-\pi^+ p \pi^0$ [BELLE-PREPRINT-2017-12; KEK-PREPRINT-2017-08; UCHEP-2017-06; arXiv:1707.00089] Physical review / D 96(5), 051102 (2017) [10.1103/PhysRevD.96.051102]   We have searched for the Cabibbo-suppressed decay $\Lambda_c^+\to\phi p\pi^0$ in $e^+e^-$ collisions using a data sample corresponding to an integrated luminosity of 915 $\rm fb^{-1}$.
