This paper discusses the statistical distribution of internal fields due to random defects in solids. It extends previous discussions by separating explicitly the contribution of the nearest defect from that due to all others. Possible applications include those to preferential defect pairing, to hopping conduction in randomly doped crystals, and to questions of the existence of phase transitio...

We consider the totally asymmetric simple exclusion process (TASEP) on the periodic chain in the presence of a single impurity site that is inaccessible to other particles and therefore acts as a static defect. Particles are allowed to advance any distance l ≥ 1 on the right with a probability that decays as l−(1+σ), where σ > 1. Despite the long range of the hopping, we find the same type of p...

The spectral problem for an infinite periodic medium perturbed by a compact defect is considered. This may be seen for example as a simplified scalar cross-sectional model of the problem for localised modes in photonic crystal fibers. For a high contrast small size periodicity and a finite size defect we consider the critical (the so called double poros-ity type) scaling. We employ (high contra...

The literature suggests that individuals with autism spectrum disorders (ASD) are deficient in their Theory of Mind (ToM) abilities. They sometimes do not seem to appreciate that behaviour is motivated by underlying mental states. If this is true, then individuals with ASD should also be deficient when they use their ToM to represent and take part in dyadic interactions. In the current study we...

We report on vortex transport in Bi2Sr2Ca1−xYxCu2O8 crystals irradiated at different doses of heavy ions. We show evidence of a flux-creep resistivity typical of a variable-range vortex hopping mechanism as predicted by Nelson and Vinokur.

2014 The conductivity of TMTSF-DMTCNQ has been measured along the main axis of the crystal as a function of temperature and irradiation dose. At room temperature the anisotropies decrease with irradiation due to the defects cutting the conducting chains into decoupled segments. A quite satisfactory fit of all the dose and temperature curves in the longitudinal and transverse directions has been...

Abstract The article presents the results of modeling a ship’s synchronous generator. Based on preliminary design calculations, geometric model generator was built. static and overclocking processes are investigated. For modes, frequency response process is obtained. A numerical used to identify mechanical defect. On example simulated defect an electrical machine - eccentricity rotor, signature...

We report on a channel drop filter with a mode gap in the propagating mode of a photonic crystal slab that was fabricated on silicon on an insulator wafer. The results, simulated with the 3-dimensional finite-difference time-domain and plane-wave methods, demonstrated that an index-guiding mode for the line defect waveguide of a photonic crystal slab has a band gap at wave vector k = 0.5 for a ...

Nomenclature and Classification There are 3 major types of ASDs or interatrial communications: ostium secundum, ostium primum, and sinus venosus (Figure 1A) defects. The ostium secundum is a true defect of the atrial septum and involves the region of the fossa ovalis. The ostium primum defect is within the spectrum of the atrioventricular (AV) septal defects (Figure 1B; also known as AV canal d...
