Within a light-cone quantum-chromodynamics dipole formalism based on the Green function technique, we study nuclear shadowing in deep-inelastic scattering at small Bjorken xBj ∼ < 0.01. Such a formalism incorporates naturally color transparency and coherence length effects. Calculations of the nuclear shadowing for the q̄q Fock component of the photon are based on an exact numerical solution of ...

This paper describes measurements which were performed to characterize shadowing in indoor radio environments. The log-normal shadowing model has been traditionally used to characterize the large scale fading component of the received power envelope in mobile and portable radio channels [1,2]. In this research we investigated the suitability of the log-normal shadowing model for indoor radio ch...

We study the genericity of the first weak inverse shadowing property and the second weak inverse shadowing property in the space of homeomorphisms on a compact metric space, and show that every shift homeomorphism does not have the first weak inverse shadowing property but it has the second weak inverse shadowing property.

We explain the early onset of shadowing in nuclear photoabsorption within a multiple scattering approach and discuss its relation to in-medium modifications of the ρ 0. The nuclear photoabsorption cross section is known to be shadowed at large energies, i.e. σ γA < Aσ γN. This was at first interpreted as a confirmation of the vector meson dominance (VMD) model, which assumes that the photon mig...

The extend to which geometrical effects contribute to the production and suppression of the J/ψ and qq minijet pairs in general is investigated for high energy heavy ion collisions at SPS, RHIC and LHC energies. For the energy range under investigation, the geometrical effects referred to are shadowing and anti-shadowing, respectively. Due to those effects, the parton distributions in nuclei de...

Background and Purpose There is little information on the distribution of atherosclerotic lesions of the extracranial carotid artery wall in free-living populations. The purpose of the present study was to describe the prevalence from 1987 through 1989 of extracranial carotid artery plaque and plaque with acoustic attenuation (shadowing) lesions in a general population of white and black adults...

Cognitive radio network maximizes number of secondary users (SUs) without affecting the service of primary users (PUs). Admittance of SUs is not only affected by the path loss but also lognormal shadowing. In this paper, we have carried out the simulation study of joint admission and power control (JAPC) algorithms: JAPCMRER and JAPC-MSSRA in presence as well as absence of log-normal shadowing....

Shadowing has become a well-known method to improve learners’ overall proficiency. Our previous studies realized automatic scoring of shadowing speech using HMM phoneme posteriors, called GOP (Goodness of Pronunciation) and learners’ TOEIC scores were predicted adequately. In this study, we enhance our studies from multiple angles: 1) a much larger amount of shadowing speech is collected, 2) ma...
