We study how much gluon shadowing can be perturbatively generated through the modified QCD evolution in heavy nuclei. The evolution of small-x gluons is investigated within the semiclassical approximation. The method of characteristics is used to evaluate the shadowed distributions in low-Q and small-x region. In solving the modified evolution equation, we model in simultaneously fusions from i...

Realism in computer graphics depends upon digitally representing what we see in the world with careful attention to detail, which usually requires a high degree of complexity in modelling the scene. With some computer graphics applications developers have to limit the complexity of the scene to allow the application to run in real-time on modern consumer grade graphics hardware. This trade-off ...

Future wireless systems are expected to provide considerably higher data rates (100 Mbit/s) than current systems. This in turn implies short-range communication with a large number of wireless access points. In order to keep the infrastructure cost down, it is imperative that the deployment of this infrastructure is fast and cheap. One possibility is to let the users themselves deploy the infra...

In this paper, using the contexts of C-class functions and common limitrange property, common fixed point result for some operator are obtained.Our results generalize several results in the existing literature. Some examplesare given to illustrate the usability of our approach.

This paper presents acoustic analysis for the purpose of automatic evaluation of shadowing speech. We use selfchecked scores of understanding, manual prosodic scores, and TOEIC scores as reference scores of learners’ shadowing speech, and compare these scores with automatic scores based on acoustic features that can reflect phoneme intelligibility and prosodic fluency in terms of intonation, an...

The absorptive corrections resulting from the rescattering of a heavy flavour (the so-called nuclear absorption) are usually calculated with a probabilistic formula valid only in the low energy limit. We extend this formula to all energies using a quantum field theoretical approach. For charmonium and bottonium we find that the absorptive corrections in the rigorous treatment are very similar t...

Nuclear shadowing in the structure function F 3 is investigated as a possible test of shadowing models. The F 3 shadowing is studied in two different theoretical models: a parton-recombination model with Q 2 rescaling and an aligned-jet model. We find that predictions in these models differ completely in the small x region. It suggests that the F 3 shadowing could be used for discriminating amo...
