The aim of this study was to analyze whether self-reported attachment style (measuring avoidance and anxiety) among adolescents was associated with dissociative symptoms, in addition to self-reported potentially traumatic experiences. A group consisting of 462 adolescents completed three self-assessment questionnaires: Linkoping Youth Life Experience Scale(More)
We have derived the general solution of a wave equation describing the dynamics of two-layer viscoelastic polymer materials of arbitrary thickness deposited on solid (quartz) surfaces in a fluid environment. Within the Voight model of viscoelastic element, we calculate the acoustic response of the system to an applied shear stress, i.e. we find the shift of(More)

Superconducting circuits that incorporate Josephson junctions are of considerable experimental and theoretical interest, particularly in the context of quantum computing. A nanometre-sized superconducting grain (commonly referred to as a Cooper-pair box) connected to a reservoir by a Josephson junction is an important example of such a system. Although the(More)
We discuss the interaction of a tunneling electron with its electromagnetic environment|when the latter either is in equilibrium or includes an applied microwave eld. The environment of an isolated tunnel junction is modeled by a set of harmonic oscillators that are suddenly displaced when an electron tunnels across the junction. We treat these displaced(More)
The dynamics of amphiphilic films deposited on a solid surface is analyzed for the case when shear oscillations of the solid surface are excited. The two cases of surface-and bulk shear waves are studied with the film exposed to gas or to a liquid. By solving the corresponding dispersion equation and the wave equation while maintaining the energy balance we(More)

We study a simple model of a self-assembled, room temperature Coulomb-blockade nanostructure containing a metallic nanocrystal or grain connected by soft molecular links to two metallic electrodes. Self-excitation of periodic grain vibrations at 10-100 GHz is shown to be possible for a sufficiently large bias voltage leading to a novel 'shuttle mechanism'(More)
The influence of long-range Coulomb interactions on the properties of one-dimensional (1D) strongly correlated electron systems in vicinity of the metal-insulator phase transition is considered. It is shown that unscreened repulsive Coulomb forces lead to the formation of a 1D Wigner crystal in the metallic phase and to the transformation of the square-root(More)
We calculate the magnetic moment ('persistent current') in a strongly correlated electron system — a Wigner crystal — in a one-dimensional ballistic ring. The flux-and temperature dependence of the persistent current is shown to be essentially the same as for a system of non-interacting electrons. In contrast , by incorporating into the ring geometry a(More)
