The phase diagram in the vector meson extended linear sigma model

We investigate the chiral phase transition of the strongly interacting matter at nonzero temperature and baryon chemical potential $\mu_B$ within an extended (2+1) flavor Polyakov constituent quark-meson model which incorporates the effect of the vector and axial vector mesons. The parameters of the model are determined by comparing masses and tree-level decay widths with experimental values. We examine the restoration of the chiral symmetry by monitoring the temperature evolution of condensates. We study the $T-\rho_B$ phase diagram of the model and find that a critical end point exists, although at very low density.Comment: 5 pages, 2 figures, Presented at CPOD 2016, Wrocla

Chiral phase transition in an extended linear sigma model: initial results

We investigate the scalar meson mass dependence on the chiral phase transition in the framework of an SU(3), (axial)vector meson extended linear sigma model with additional constituent quarks and Polyakov loops. We determine the parameters of the Lagrangian at zero temperature in a hybrid approach, where we treat the mesons at tree-level, while the constituent quarks at 1-loop level. We assume two nonzero scalar condensates and together with the Polyakov-loop variables we determine their temperature dependence according to the 1-loop level field equations.Comment: Presented at the Workshop on Unquenched Hadron Spectroscopy: Non-Perturbative Models and Methods of QCD vs. Experiment, At the occasion of Eef van Beveren's 70th birthda

Charmonium spectral functions in pˉA\bar p A collision

We study the in-medium propagation of low-lying charmonium states: $J/\Psi$, $\Psi$(3686), and $\Psi$(3770) in a $\bar p$ Au $10$ GeV collision. This energy regime will be available for the PANDA experiment. The time evolution of the spectral functions of the charmonium states is studied with a BUU type transport model. We observe a substantial effect of the medium in the dilepton spectrum.Comment: 6 pages, 4 figures, Presented at Excited QCD 2017, Sintra, Portuga

Linear Matrix Inequality-based Robust Controller design for Type-1 Diabetes Model

This paper investigates the capabilities of a sophisticate d robust nonlinear controller designed directly for a widely known and used high-order non linear type 1 diabetes (T1DM) model to lessen the dependency from patient compliance and t o answer practical requirements such as avoiding hypoglycaemia. The resulting controller c an perform adequately in nominal conditions, but expected to keep this performance even in ex treme situations, e.g. high carbohydrate intake, rejecting hypoglycaemic episodes

ANALYSIS OF THE CHLORIDE BINDING ABILITY OF CEMENTS

We examined the binding process of NaCI penetrating into hardened cements from outer source through Hungarian manufactured cements representing both general and special fields of application. These types are the following: 450 Rpc, S 54, 350 ppc 20 and 250 kspc 60. We observed the effect of chlorides entering cements (between 1-28 and 28-56 days) by thermal analysis and X-ray diffraction spectroscopy. X-ray diffraction analysis proved that the chloride ion of NaCI is bound by C₃A and C₄AF in the form C₃A· CaCl₂ · H₁₀ containing ferrite. Chloro-aluminate-hydrates were formed not only in the first phase of hydration but in the hardened cement as well by the substitution of anions of the present AFm phases: C₃A· CaS0₄· H₁₂,, C₃A· Ca(OH)₂ . H₁₂, C₃A· CaC0₃· H₁₁. Neither X-ray diffraction nor thermal analysis investigations detected any chlorous calcium-silicate-hydrates

Deviation from the Fourier law in room-temperature heat pulse experiments

We report heat pulse experiments at room temperature that cannot be described by Fourier's law. The experimental data is modelled properly by the Guyer--Krumhansl equation, in its over-diffusion regime. The phenomenon is due to conduction channels with differing conductivities, and parallel to the direction of the heat flux.Comment: 9 pages, 4 figure
