This paper presents empirical support for a new observer model of inferring three-dimensional shape from monocular texture cues. By measuring observers' abilities to estimate the relative three-dimensional curvature along a textured surface from two-dimensional projected images, and concurrently examining the local spectral changes occurring in the projected image for various texture patterns, ...

One-dimensional (1D) subwavelength corrugated metal structures has been described to support spoof surface plasmon polaritons (SPPs). Here we demonstrate that a periodically modulated 1D subwavelength corrugated metal structure can convert spoof SPPs to propagating waves. The structure is fed at the center through a slit with a connected waveguide on the input side. The subwavelength corrugated...

This article is devoted to computer and experimental modeling of the behavior flexible elements shell structures, development effective algorithms for solving emerging nonlinear boundary value problems their calculation optimization parameters. At same time, probability results obtained using different approaches construction a theory established. Their comparative analysis, error estimation, w...

We examine pressure-driven nonequilibrium transport of linear, circular, and star polymers through a nanochannel containing a rectangular pit with full hydrodynamic interactions and thermal fluctuations. We demonstrate that with sufficiently small pressure differences, there is contour length-dependent entropic trapping of the polymer in the pit when the pit and the polymer sizes are compatible...

Much attention has been devoted to the synthesis and characterization of organic–inorganic multilayered perovskites owing to the tunability of their structural features.1–5 The physical and structural properties of these compounds can be fine tuned by substituting or tailoring the organic layers or by modulating the thickness of the perovskite inorganic slabs. Applications of layered perovskite...

Transhiatal oesophagectomy is an established technique for resection of tumours of the lower oesophagus and oesophagogastric junction. The authors describe a previously unreported serious complication associated with placement of a corrugated neck drain during transhiatal oesophagectomy. A 63 year old man was admitted for transhiatal oesophagectomy for resection of a lower third oesophageal tum...

Corrugated waveguide transmission lines are in use to transmit high power mm-wave radiation from gyrotrons to the plasma for electron cyclotron plasma heating in tokamaks such as ITER. The coupling efficiency of the gyrotron output radiation formed as a quasi-Gaussian beam to the waveguide mode is a critical issue. A hyperbolic corrugated horn serves as a converter of the TEM00 Gaussian mode to...

In this letter, we propose the use of the newly developed corrugated quantum well infrared photodetectors ~C-QWIPs! for polarization detection. The corrugated structure, which serves as an optical coupler as well as the polarization-sensitive component, is in this case directly created into the active region of the QWIP, therefore dispensed with the need of an external polarizer. Moreover, four...

In the fresh produce industry, corrugated containers must be made to provide adequate protection throughout the product life cycle. In response to increasing materials costs in the corrugated industry, companies are focusing upon developing more efficient packaging designs. The scope of this project focuses on presenting alternative corrugated packaging designs for the fresh produce industry. I...
