A new type of an integrable mapping is presented. This map is equipped with fractional difference and possesses an exact solution, which can be regarded as a discrete analogue of the Mittag-Leffler function.

The main object of this paper is to investigate the solution of the following free electron laser equations associated with generalized MittagLeffler function and a confluent hypergeometric function in two variables: Dα τ h(τ) = ω ∫ τ 0 t β−1 h(τ − t)E σ,β(iνt σ)dt+ δf(τ), where γ, δ, ω ∈ C; ν ∈ R,α > 0, σ > 0, β > 0; E σ,β(z) is the generalized Mittag-Leffler function and Dα τ h(τ) = λ Γ(γ) ∫ ...

The third meeting of the Group was held on 13-15 June 1995 at the headquarters of the OIE. It was opened by Dr J. Blancou, Director General of the OIE, who welcomed the participants (listed in Appendix I). Drs P. Chardonnet and T. Mörner sent their apologies. Dr M.H. Woodford was elected chairman of the meeting, and Drs M. Artois and R. Bengis were elected as rapporteurs. The agenda (Appendix I...

We describe a Jordan-algebraic version of results related to convexity of images of quadratic mappings as well as related results on exactness of symmetric relaxations of certain classes of nonconvex optimization problems. The exactness of relaxations is proved based on rank estimates. Our approach provides a unifying viewpoint on a large number of classical results related to cones of Hermitia...

Background: The natural orifice transluminal endoscopic surgery (NOTES) has become a commonly considered novel approach in the surgical field. The NOTES provide possibility of operation through the natural orifice and decreases the intentional puncture of the systemic organ and subsequent complications. Totally transanal laparo-endoscopic single-site proctoColectomy-Ileoanal J-Pouch (TLPC-J) is...

During B and T cell development, the RAG1/RAG2 protein complex cleaves DNA at conserved recombination signal sequences (RSS) to initiate V(D)J recombination. RAG1/2 has also been shown to catalyze transpositional strand transfer of RSS-containing substrates into target DNA to form branched DNA intermediates. We show that RAG1/2 can resolve these intermediates by two pathways. RAG1/2 catalyzes h...

The RAG-1 protein plays an essential role in V(D)j recombination, but its exact function has not yet been defined. Here we report that a particular mutation in RAG-1 affects recombination by altering the specificity of target sequence usage. Recombination mediated by wild-type RAG-1 is tolerant of a wide range of coding sequences adjacent to the recombination signal. With the mutant RAG-1, reco...
