This paper presents an experimental and numerical study of composite plates, analyzing the interaction between mechanical thermal loads related to buckling occurrence mode jumping. A novel setup for thermomechanical testing was developed. The is conceived around a frame with low coefficient expansion, so that plate can experience jumping when heated; compressed, interactions two loading states ...

In tapping mode atomic force microscopy (AFM) the highly nonlinear tip-sample interaction gives rise to a complicated dynamics of the microcantilever. Apart from the well-known bistability under typical imaging conditions the system exhibits a complex dynamics at small average tip-sample distances, which are typical operation conditions for mechanical dynamic nanomanipulation. In order to inves...

Abstract. The hybrid MHD-Gyrokinetic model has been proven to be very successful in describing the coupling between Alfvén waves and energetic particles and their mutual interaction in toroidal devices. HMGC, the nonlinear MHD-Gyrokinetic code originally developed at the Frascati laboratories, is being currently extended to include new physics. In this paper we will present the first simulation...

We have investigated plasmonic excitations at the surface of Bi_{2}Se_{3}(0001) via high-resolution electron energy loss spectroscopy. For low parallel momentum transfer q_{∥}, the loss spectrum shows a distinctive feature peaked at 104 meV. This mode varies weakly with q_{∥}. The behavior of its intensity as a function of primary energy and scattering angle indicates that it is a surface plasm...

The hydrogen and water molecules are ubiquitous in the Universe. Their mutual collisions drive water masers and other line emission in various astronomical environments, notably molecular clouds and star-forming regions. We report here a full nine-dimensional interaction potential for H2O-H2 calibrated using high-accuracy, explicitly correlated wave functions. All degrees of freedom are include...

A number of studies have contributed to demonstrate that neurons and astrocytes tightly and actively interact. Indeed, the presence of astrocytes in neuronal cultures increases the number of synapses and their efficiency, and thanks to enzymatic and uptake processes, astrocytes play a role in neuroprotection. A typical feature of astrocytes is that they establish cell-cell communication in vitr...
