We propose a novel approach to continuum modeling of the dynamics of crystal surfaces. Our model follows the evolution of an ensemble of step configurations, which are consistent with the macroscopic surface profile. Contrary to the usual approach where the continuum limit is achieved when typical surface features consist of many steps, our continuum limit is approached when the number of step ...

The Balitsky-Fadin-Kuraev-Lipatov (BFKL) evolution equation is known to be " unstable " with respect to fluctuations in gluon virtuality, transverse momentum and energy requiring to go beyond the leading order BFKL. Still, these instabil-ities point to fruitful improvements of our deep understanding of QCD. Recent applications to next-leading order and to saturation problems are outlined.

This article provides multiple parallel readings of the records continuum model in relation to a single case study. The purpose of these multiple readings is to illustrate the capacity of the model to support different interpretations, simultaneously, depending on the context. The article demonstrates that the records continuum theory and model is not a straightjacket for linear application of ...

This paper explores potential advantages of using virtual teams for small and medium-sized enterprises (SMEs) with a comprehensive review on various aspects of virtual teams. Based on the standing of the pertinent literatures, attempt has been made to study the aspects by online survey method in Iran and Malaysia. In both countries, SMEs play an important role in their economies, employments, a...

The charm contribution into the proton structure function in DIS at the HERA ep-collider Abstract In the framework of perturbative QCD and a model for the production of charmed hadrons the structure function F c 2 is calculated and compared with the experimental data of H1 and ZEUS Collaborations. We show that the spectator mechanism of the D *-meson production independent of a hadronic remnant...

We study a novel property of large rapidity-gap events in deep inelastic scattering at HERA: splitting the pomeron into two jets in the photon-pomeron fusion reaction γIP → qq̄. It gives rise to the diffraction dissociation of virtual photons into the back-to-back jets. We find that at large invariant mass M of two jets, M ≫ Q, the transverse momentum of jets comes from the intrinsic transverse ...

Article history: Received 30 May 2016 Accepted 2 August 2016 Available online 5 August 2016 Editor: A. Ringwald We consider the effect of the Sudakov factor in photon-initiated processes, corresponding to the no branching probability for the initial-state photon. We demonstrate how such a factor follows simply from the solution of the DGLAP equation for the photon PDF, and is therefore included...

The curvature of DIS structure functions like F p 2 (x,Q ), i.e., its second derivative with respect to the photon’s virtuality Q at fixed values of x, plays a decisive role in probing the range of validity of perturbative QCD evolutions of parton distributions in the small-x region. This has been observed recently [1, 2, 3, 4] and it was demonstrated that NLO(MS) evolutions imply a positive cu...

We model the dynamics of an ad-hoc sensor network as a continuum percolation model, and prove that a simple local-flooding technique yields an efficient communication protocol in that setting.  2004 Elsevier Inc. All rights reserved.
