    On Field Induced Diaelastic Effect in a Small Josephson Contact

    Full text link
    An analog of the diaelastic effect is predicted to occur in a small Josephson contact with Josephson vortices manifesting itself as magnetic field induced softening of the contact shear modulus C(T,H). In addition to Fraunhofer type field oscillations, C(T,H) is found to exhibit pronounced flux driven temperature oscillations near T_C

    Formation of coherent structures and patterns from unstable uniform state or noise is a fundamental physical phenomenon that occurs in various areas of science ranging from biology to astrophysics. Understanding of the underlying mechanisms of such processes can both improve our general interdisciplinary knowledge about complex nonlinear systems and lead to new practical engineering techniques. Modern optics with its high precision measurements offers excellent test-beds for studying complex nonlinear dynamics, though capturing transient rapid formation of optical solitons is technically challenging. Here we unveil the build-up of dissipative soliton in mode-locked fibre lasers using dispersive Fourier transform to measure spectral dynamics and employing autocorrelation analysis to investigate temporal evolution. Numerical simulations corroborate experimental observations, and indicate an underlying universality in the pulse formation. Statistical analysis identifies correlations and dependencies during the build-up phase. Our study may open up possibilities for real-time observation of various nonlinear structures in photonic systems

    The description and results of realization of the pilot project within the second stage of primary accreditation of specialists in 2017 (specialty «Medical job») are briefly presented. The pilot project’s goal is to assess the real opportunities of realization examination of the effective communicative skills to with patients during the collection of complaints and anamnesis on a primary outpatient medical appointment. The pilot station was tested in two universities: the First Moscow State Medical University and the Urals State Medical University, Yekaterinburg.Кратко представлены описание и результаты реализации пилотного проекта в рамках второго этапа первичной аккредитации специалистов в 2017 году (специальность «Лечебное дело»). Цель пилота — оценка возможностей реализации экзамена по владению практическими навыками эффективного общения с пациентами при сборе жалоб и анамнеза на первичном амбулаторном врачебном приеме. Пилотная станция проходила апробацию в двух вузах: Первом Московском государственном медицинском университете им. И.М. Сеченова и Уральском государственном медицинском университете, г. Екатеринбург
