This paper proposes a new method for natural-image deblur based on a single blurred image. The natural image prior, a sparse gradient distribution, is enforced using a gradient histogram remapping method in the proposed ...
We give a rigorous semianalytical definition of impedance for square and triangular (hexagonal) lattice two-dimensional photonic crystals (PCs). Our impedance is a small matrix, derived from transfer matrices, which stores ...
We implement a flexible Z-matrix approach in the density functional theory (DFT) periodic boundary conditions code, SIESTA. This allows a mixture of Z-matrix and Cartesian coordinates to be used for geometry specification ...
This paper, as a pioneering work, presents measurement techniques to characterize soft magnetic materials in three-dimensional (3D) space. A novel 3D magnetic property tester using cubic sample has been constructed and ...
This paper analyzes the effect of the internal field on the measurement with two-dimensional (2-D) rotating fluxes. It is demonstrated that due to the effect of the internal field, the misalignment of H sensing coils, ...

YBa2Cu3O7 films were fabricated by pulsed laser deposition on SrTiO3 s100d single-crystal
substrates whose surfaces were modified by the introduction of Ag nanodots. The critical current
density sJcd was found to increase ...
Impulsive responses in geared systems with multiple clearances are studied when the mean torque excitation and system load change abruptly, with application to a vehicle driveline with an automatic transmission. First, ...
In sub-stoichiometric MoO3, electrical and optical responses across the solar spectrum are tunable and manifest a sharp phase transition in thin films at a specific oxygen content. Models of optical response in insulating ...

Metal laminates have experienced rapid development in many engineering applications and generally possess enhanced properties with improved service performance. Roll bonding is a major technique used in manufacture of metal ...
Material grown by room temperature electron beam induced deposition (EBID) using (CH(3))(3)CH(3)C(5)H(4)Pt precursor consists of platinum nanocrystals embedded in an amorphous matrix. The crystallites are shown to intermix ...
Ultra-thin films are of interest in the production of X-ray mirrors that use a multilayer structure. The most commonly used deposition techniques are dc magnetron sputtering and electron beam evaporation; this paper presents ...
We study the radiation dynamics of an electric dipole source placed near or inside a discrete invisibility cloak. We show that the main features of radiation dynamics can be understood in terms of the interaction of the ...
In this work, the flow of the Josephson vortices (JVs) has been studied for the highly anisotropic Bi2Sr2Ca2Cu3Oy (Bi2223) single crystals. A giant flow of JVs or giant positive magnetoresistance (MR) of over 500%-2000% ...
We report on the magnetoresistance (MR) and magnetic properties of In1.90-xMn0.1SnxO3 (0 <= x <= 0.06) oxide. All samples were found to be ferromagnetic below T-C=46 K. Sn doping changed In1.90Mn0.1O3 from an insulator to ...
A dynamic model of a coupled train-girder-pier system is developed in this paper. Each vehicle in a train is modeled with 27 degrees-of-freedom for a 4-axle passenger coach or freight car, and 31 for a 6-axle locomotive. ...
The lattice parameters of a metallic nanoparticle decrease with its size. To describe this phenomenon, a model based on elasticity is developed in this paper. Using this model, we investigate the lattice contraction of a ...

Figure Persented: Nanoporous gold and silver exhibit strong, omnidirectional broad-band absorption in the far-field. Even though they consist entirely of gold or silver atoms, these materials appear black and dull, in great ...

Local quantum operations and classical communication (LOCC) put considerable constraints on many quantum information processing tasks such as cloning and discrimination. Surprisingly, however, discrimination of any two ...
