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 ...

We calculate the shadowing of sea quarks and gluons and show that the shadowing of gluons is not simply given by the sea quark shadowing, especially at small x. The calculations are done in the lab frame approach by using the generalized vector meson dominance model. Here the virtual photon turns into a hadronic fluctuation long before the nucleus. The subsequent coherent interaction with more ...

We calculate the x dependence of nuclear shadowing at moderate values of Q by using HERA diffractive data. We show that no decrease of shadowing occurs down to very low x (x ≃ 10). Also at II Facoltà di Scienze MFN, 15100 Alessandria, Italy. Supported by EU Contract ERBFMBICT950427. The possibility of studying nuclear shadowing (i.e. the depletion of bound nucleon structure functions (F 2 ) wit...

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...

The interest in using higher frequency bands for high data rate wireless communication is increasing. Large unlicensed bandwidths are available specifically around 60 GHz. At this frequency, the propagation characteristics allow small cells and efficient frequency reuse. However, wireless communication at 60 GHz is mainly limited to Line-of-Sight (LOS), due to the high absorption loss of most m...

This paper presents the shadowing analysis of a body area network (BAN) diversity antenna based on the statistical measurements of the human walking motion. First, the dynamic characteristics of the armswing motion were measured using human subjects, and a statistical analysis was then carried out using the measured data to extract useful information for the analysis of a BAN diversity antenna....

VMS Volume Shadowing Overview Phase II is a fully distributed, clusterwide Volume shadowing is a data availability product technique that provides designed to replace the data availability to obsolete controller-based computer systems by shadowing implementation. protecting against Phase II is intended data loss from media to service current and deterioration, future generations of communicatio...

Speech shadowing is a dual-task paradigm that could reveal certain features of speech processing, where the shadowing latency between the onsets of heard and reproduced speech has often been a key investigation tool. The present study investigated the shadowing latencies in native Japanese adults who do (AWS) and do not stutter (AWNS), with relevant analysis of speech errors. Fifteen AWS and fo...

Flaminio Borgonovo, Michele Zorzi, Luigi Fratta Abstract—Recently, a new method for achieving spectrum reuse in cellular systems, called Capture-Division Packet Access (CDPA), has been introduced. The method uses a single frequency in all cells, and exploits packet switching and packet retransmission as a means to overcome destructive cochannel interference. As the CDPA key factor is packet ret...
