Na jakich podstawach opiera się mechanika klasyczna: odpowiedź historyka nauki
The author tries to give an answer to the question posed in the title of the paper by referring to those analyses and arguments which have been found important by the history of science (laws of Stevin, d\u27Alembert, Lagrange, arguments of Lazure Carnot, Prony, Ampère, Laplace…). In his opinion the only possible philosophy of mechanics must have the empirical nature. The problem was perceived already by Archimedes, though it was later obscured by numerous metaphysics. Yet, it is only solution of Lagrange which can be said to be approaching the ideal. However, the philosophical part of the arguments still remains unsettled

Dielectron measurements in pp and Pb–Pb colllisions with ALICE at the LHC
The production of low-mass dielectrons is one of the most promising tools for the investigation of chiral symmetry restoration and thermal radiation from the QGP created in heavy-ion collisions. To single out the signal characteristics of the QGP, it is crucial to understand the primordial pair production in vacuum, i.e. in inelastic proton-proton (pp) collisions. Low-mass dielectrons have been measured with ALICE at the LHC in pp collisions at , and in Pb–Pb collisions at TeV. An overview of the results on dielectron production is presented, together with their implications for the direct-photon and heavy-quark production
What Are the Grounds of Classical Mechanics? — the Reply of the History of Science

Open heavy-flavor measurements with ALICE at the LHC
ALICE is well equipped to reconstruct heavy-flavor particles down to low transverse momentum pT at mid and forward rapidity. An overview of the ALICE results obtained with the Run 1 data in pp (√5=2.76TeV and √s=7TeV), Pb-Pb (√Snn=2.76TeV) and p-Pb (√sNN=5.02 TeV) collisions is presented. In pp collisions the measured cross sections are well described by pQCD calculations. The charged-particle multiplicity dependence of heavy-flavor yields indicates that Multi-Parton Interactions contribute to the high-multiplicity pp collisions and affect charm and beauty production in a similar way. In p-Pb and Pb-Pb collisions the measured nuclear modification factors indicate a final-state energy loss of heavy- quarks in central Pb-Pb collisions. Furthermore, the observed positive heavy-flavor elliptic flow in semi-central Pb-Pb collisions gives a hint that charm quarks participate in the collective expansion of the medium at low pT. In high-multiplicity p-Pb collisions, a double-ridge structure is observed in the heavy-flavor decay electron-hadron azimuthal correlations at low pT similar to what is measured in the light-flavor sector. Such long-range correlations in ŋ could originate from a collective expansion of the system, as well as from gluon saturation in the initial state (color-glass condensate) or other mechanisms
Initial clinical presentation of young children with N-methyl-D-aspartate receptor encephalitis
Autoimmune encephalitis with anti-N-methyl-D-aspartate receptor autoantibodies (NMDA-R-Abs) is a recently described disease affecting adult and pediatric patients. Symptoms of the disease are now perfectly described in the adult population but the clinical presentation is less known in young children. The aim of the present study was to describe the clinical presentation and the specificities of symptoms presented by young children with NMDA-R-Abs encephalitis to improve diagnosis of this disease, and to compare these to a series of previously published female adult patients. Fifty cases of children younger than twelve years of age diagnosed with NMDA-R-Abs encephalitis between January 1, 2007 and December 31, 2016 (27 females and 23 males) were retrospectively studied. The first neurological symptoms observed in young children with NMDA-R-Abs encephalitis were characterized by seizure (72%), especially focal seizure (42%), within a median of 15 days before other encephalitis symptoms; other patients mostly had behavioral disorders (26%). The seizures were frequently difficult to diagnose because of the transient unilateral dystonic or tonic posturing presentation or sudden unilateral pain in the absence of clonic movements. A post-ictal motor deficit was also frequently observed. This clinical presentation is different from that observed in adult females with NMDA-R-Abs encephalitis who initially present mainly psychiatric disorders (67%) or cognitive impairment (19%), and less frequently seizures (14%). The diagnosis of NMDA-R-Abs encephalitis should be systematically considered in young children of both sexes who present neurological symptoms suggesting recent seizures (focal or generalized) without obvious other etiology
Z0 Boson Measurement with the ALICE Central Barrel in pp collisions at 14 TeV
The possibility to detect the Z0 in the ALICE central barrel is studied via the electronic decay channel Z0->e+e-. The signal and the background are simulated with the leading order event generator PYTHIA 6. The total cross-sections are taken from NLO calculations. Based on test beam data, the electron identification performance of the Transition Radiation Detector is extrapolated to high momenta. The expected yields for minimum-bias pp collisions at 14 TeV are presented. An isolation cut on the single electron, together with a minimum transverse momentum cut, allows to obtain a clear signal. The expected background is of the order of 1 % with the main contribution coming from misidentified pions from jets.The possibility to detect the Z0 in the ALICE central barrel is studied via the electronic decay channel Z0->e+e-.
