In standard quantitative models, bilateral trade imbalances are determined by aggregate imbalances, expenditure and production patterns, wedges. We calibrate such a model using recent data on incomes, factor endowments, sector-level expenditures, outputs flows for 40 economies the rest of world. Large pairwise asymmetries in wedges needed model’s bilateral-trade predictions to match data. They ...

Tectonic activity in the Mediterranean area (involving migrations of old orogenic belts, formation basins and building systems) has been determined by convergence confining plates (Nubia, Arabia Eurasia). Such mainly accommodated consumption oceanic thinned continental domains, triggered lateral escapes wedges. Here, we argue that implications above basic concepts can allow plausible explanatio...

We outline specific features of numerical simulations of metamaterial wedges and interfaces. We study the effect of different positioning of a grid in the Yee method, which is necessary to obtain consistent convergence in modeling of interfaces with metamaterials characterized by negative dielectric permittivity and negative magnetic permeability. We demonstrate however that, in the framework o...

We present an analytical study in the structure-modulated plasmonic angular momentum, which is trapped in the core region of a sectorial indefinite metamaterial. This metamaterial consists of periodically arranged metal-dielectric nano-wedges along the azimuthal direction. Employing a transfer-matrix calculation and a conformal-mapping technique, our theory can deal with an arbitrary number of ...

Ultrasonic wedges which can propagate one longitudinal L and two orthogonally polarized shear S waves are presented. In order to use this wedge to generate and received guided plate acoustic waves along a metal plate at high temperatures brass which has a slow L and S wave velocities was chosen. Mode conversion method was used to convert L to S waves in the wedge. The mode conversion efficiency...
