Transition-metal-catalyzed cross-coupling reactions are among the most powerful synthetic transformations. This paper describes an efficient copper-catalyzed homo- and cross-coupling of Grignard reagents with di-tert-butyldiaziridinone as oxidant under mild conditions, giving the coupling products in good to excellent yields. The reaction process has a broad substrate scope and is also effectiv...

A precise measurement of the inclusive deep-inelastic ep scattering cross section is discussed in the kinematic range 1.5 ≤ Q ≤ 150GeV and 3 ·10−5 ≤ x ≤ 0.2. The data were recorded with the H1 detector at HERA in 1996 and 1997, and correspond to an integrated luminosity of 20 pb−1. The double differential cross section was measured with typically 1% statistical and 3% systematic uncertainties. ...

In this paper we perform a numerical study of the tranverse expansion of hadronic scattering amplitudes in high energy QCD, by using the dipole picture. We go beyond the mean field approximation by including fluctuations and also wave function saturation effects, and the evolution with both a fixed and a running coupling is investigated. We also study the nonperturbative aspects, and as has bee...

Recent proposals have looked at the requirements stage, using the aspect oriented programming, trying to separate and after to compose the concerns that are spread and tangled in the requirement document. New factors appear in these requirements documents, such as, crosscutting concerns, size and coupling are not qualitative evaluated, because there are not these metrics. This paper shows a set...

We suggest that the pseudo-rapidity cut dependence of diffractive deep-inelastic scattering events at HERA may provide a sensitive test of models of diffraction. A comparison with the experimental cross section shows that the Donnachie-Landshoff model and a simple two-gluon exchange model of the pomeron model are disfavoured. However a model with a direct coupling of the pomeron to quarks is vi...

Pion multiplicity in heavy-ion collisions at the beam energies of about 1 A GeV [1, 2] is usually overpredicted by transport calculations with vacuum cross sections. Recently [3] we proposed to take into account the in-medium modifications of the NN → N∆ cross section, namely, the exchange pion collectivity, vertex renormalization by the contact nuclear interactions and Dirac effective masses o...

PAMAM dendrimers of generations G2-G3 as well as a partially substituted derivative of generation G4 and a low-molecular-weight tricyclic ligand 4 were used to bind Pd(0) nanoparticles. The obtained adducts were tested as catalysts for C-C cross-coupling reactions, such as the Suzuki-Miyaura, Hiyama, Heck and Sonogashira reaction. The highest yields of the coupling product, diphenylacetylene, w...

We describe a recent progress in finding solutions to three-particle evolution equations at leading order in the QCD coupling constant for multiparton correlation functions based on the integrability of corresponding interaction Hamiltonians.
