 Multiplicity dependence of identified particle production in PP collisions with ALICE / Nayak, Kishora (NISER, Jatni) /ALICE On behalf of the ALICE Collaboration A comprehensive measurement of the multiplicity dependence of identified particle production in proton-proton (pp) collisions is important for the understanding of small and large colliding systems. The transverse momentum (pT) dependence of particle ratios and the integrated yield ratio of various particles such as π, K, K 0 S , K * 0 , p, Λ, Ξ, Ω in pp collisions at 7 TeV are reported.

 Design and Test of a GBTX-Based Board for the Upgrade of the ALICE TOF Readout Electronics / Falchieri, D (INFN, Bologna) ; Antonioli, P (INFN, Bologna) ; Baldanza, C (INFN, Bologna) ; Giorgi, F M (INFN, Bologna ; U. Bologna, DIFA) ; Mati, A (CAEN, Viareggio) ; Tintori, C (CAEN, Viareggio) In order to cope with the increased luminosity that the European Organization for Nuclear Research large hadron collider accelerator will provide after Long Shutdown 2 (2019- 2020), the a large ion collider experiment (ALICE) Time-Of-Flight (TOF) readout board data readout module is currently being redesigned. As a first step toward the final design, a test board hosting a Microsemi Igloo2 field-programmable gate array (FPGA), the radiation-hard Application-Specified Integrated Circuit (ASIC) gigabit transceiver ASIC (GBTX), and the optical transceiver versatile link transceiver (VTRX) has been designed and extensively tested.

 The upgrade of the ALICE Inner Tracking System / Ravasenga, Ivan (Turin Polytechnic ; INFN, Turin) /ALICE In 2021, for the third run of the CERN Large Hadron Collider (LHC), Pb-Pb collisions will be performed at a centre-of-mass energy per nucleon of 5.5 TeV, with an integrated luminosity of $6 \times 10^{27}$ cm$^{-2}$ s$^{-1}$ and at an unprecedented interaction rate up to 50 kHz. To fulfil the requirements of the ALICE physics program for Run 3, the ALICE experiment at LHC is planning a major upgrade during the Long Shutdown 2 of LHC in 2019-2020.

 Open heavy-flavour measurements in Pb-Pb collisions with ALICE at the LHC / Mischke, André (Utrecht U. (main)) /ALICE The ALICE experiment has measured charm and beauty production in Pb–Pb collisions at $\sqrt{S_{\rm{NN}}}= 2.76 \text{ TeV}$ and $5.02 \text{ TeV}$, via the reconstruction of hadronic D-meson decays and semi-leptonic Dand B-meson decays. In this contribution, an overview is given on current open heavy-flavour results from ALICE ranging from the nuclear modification factor to elliptic flow measurements and on the interpretation of the data by comparing with different model calculations of in-medium energy loss..
