    Статья поступила в редакцию 13.01.2022 г.Статья посвящена творчеству современной американской писательницы Д. Тартт. Выделяются жанровые и нарративные конституции young adult literature в ее романах, которые описываются в контексте опоры на поэтику романов Ф. М. Достоевского. В статье осуществляется реконструкция мифологических и символических моделей и образов в произведениях Д. Тартт и Ф. М. Достоевского, а также генетических и типологических связей как в жанровых, так и в сюжетных структурах романов «Щегол» и «Идиот».This article is centered on the work of the modern American writer D. Tartt. The genre and narrative constitutions of young adult literature are highlighted in her novels, which are described in the context of relying on the poetics of F. M. Dostoevsky’s novels. The article reconstructs mythological and symbolic models and images in the works of D. Tartt and F. M. Dostoevsky, as well as genetic and typological connections, both in genre and in the plot structures of the novels “The Goldfinch” and “The Idiot”

    We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of 2.1 x 10(14) and 7.7 x 10(14) electrons/cm(3). We show that these wakefields periodically defocus the proton bunch itself, consistently with the development of the seeded self-modulation process. We show that the defocusing increases both along the bunch and along the plasma by using time resolved and time-integrated measurements of the proton bunch transverse distribution. We evaluate the transverse wakefield amplitudes and show that they exceed their seed value (< 15 MV/m) and reach over 300 MV/m. All these results confirm the development of the seeded self-modulation process, a necessary condition for external injection of low energy and acceleration of electrons to multi-GeV energy levels

    Experimental Observation of Proton Bunch Modulation in a Plasma at Varying Plasma Densities

    We give direct experimental evidence for the observation of the full transverse self-modulation of a long, relativistic proton bunch propagating through a dense plasma. The bunch exits the plasma with a periodic density modulation resulting from radial wakefield effects. We show that the modulation is seeded by a relativistic ionization front created using an intense laser pulse copropagating with the proton bunch. The modulation extends over the length of the proton bunch following the seed point. By varying the plasma density over one order of magnitude, we show that the modulation frequency scales with the expected dependence on the plasma density, i.e., it is equal to the plasma frequency, as expected from theory

    Optoelectronic properties of CuPc thin films deposited at different substrate temperatures

    Structural and optical characterization of copper phthalocyanine thin film thermally deposited at different substrate temperatures was the aim of this work. The morphology of the films shows strong dependence on temperature, as can be observed by atomic force microscopy and x-ray diffraction spectroscopy, specifically in the grain size and features of the grains. The increase in the crystal phase with substrate temperature is shown by x-ray diffractometry. Optical absorption coefficient measured by photothermal deflection spectroscopy and optical transmittance reveal a weak dependence on the substrate temperature. Besides, the electro-optical response measured by the external quantum efficiency of Schottky ITO/CuPc/Al diodes shows an optimized response for samples deposited at a substrate temperature of 60 °C, in correspondence to the I-V diode characteristics
