    The present work continues a series of the KEDR measurements of the RR value that started in 2010 at the VEPP-4M e+eβˆ’e^+e^- collider. By combining new data with our previous results in this energy range we measured the values of RudsR_{\text{uds}} and RR at nine center-of-mass energies between 3.08 and 3.72 GeV. The total accuracy is about or better than 2.6%2.6\% at most of energy points with a systematic uncertainty of about 1.9%1.9\%. Together with the previous precise RR measurement at KEDR in the energy range 1.84-3.05 GeV, it constitutes the most detailed high-precision RR measurement near the charmonium production threshold.Comment: arXiv admin note: text overlap with arXiv:1610.02827 and substantial text overlap with arXiv:1510.0266

    The article reports a clinical case of a patient with four recurring episodes of headache, nausea and focal neurological symptoms (hemiparesis, sensorimotor aphasia, adversive epileptic seizures) with a rapid onset of remission. The clinical picture of the disease was supplemented with lymphocytic pleocytosis and cell-protein dissociation in the cerebrospinal fluid, which allowed to diagnose benign recurrent lymphocytic meningitis (Mollaret meningitis) and to conduct pathogenetic therapy. The aim of this work is to improve the diagnosis of rare Mollaret meningitis.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ приводится описаниС клиничСского случая  развития Ρƒ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚Π° Ρ‡Π΅Ρ‚Ρ‹Ρ€Π΅Ρ… Ρ€Π΅Ρ†ΠΈΠ΄ΠΈΠ²ΠΈΡ€ΡƒΡŽΡ‰ΠΈΡ… эпизодов Π³ΠΎΠ»ΠΎΠ²Π½ΠΎΠΉ Π±ΠΎΠ»ΠΈ, Ρ‚ΠΎΡˆΠ½ΠΎΡ‚Ρ‹ ΠΈ ΠΎΡ‡Π°Π³ΠΎΠ²ΠΎΠΉ нСврологичСской симптоматики (Π³Π΅ΠΌΠΈΠΏΠ°Ρ€Π΅Π·, сСнсомоторная афазия, адвСрсивныС эпилСптичСскиС ΠΏΡ€ΠΈΠΏΠ°Π΄ΠΊΠΈ) с быстрым наступлСниСм рСмиссии.

    Measurement of the branching fraction of J/Οˆβ†’ΟΟ€J/\psi\rightarrow\rho\pi at KEDR

    Full text link
    We present the study of the decay J/Οˆβ†’ΟΟ€J/\psi \rightarrow \rho \pi. The results are based on of 5.2 million J/ψJ/\psi events collected by the KEDR detector at VEPP-4M collider. The branching fraction is measured to be B(J/Οˆβ†’ΟΟ€)=(2.072Β±0.017Β±0.056)β‹…10βˆ’2\mathcal{B}(J/\psi\rightarrow\rho\pi) = \big(2.072\pm 0.017 \pm 0.056 \big)\cdot 10^{-2} where the first uncertainty is statistical, the second one is systematic. This is the most precise single measurement of this quantity at the moment

The authors analyse different approaches to professional success rate, considering social competence as the main agency. On the ground of studing the influence of extra-curricular activities to forming as elements of students’ social competence as understanding of their values and getting ahead motivation, the authors have concluded that the success rate is connected with the social competence
