We address the question whether the cut-off dependence, which has to be introduced in order to properly define the Lippmann-Schwinger equation for the one pion exchange potential plus local (δ-function) potentials, can be removed (up to inverse powers of it) by a suitable tuning of the various (bare) coupling constants. We prove that this is indeed so both for the spin singlet and for the spin ...

Abstract Trapped-mode frequencies are computed for submerged, horizontal, circular cylinders in a two-layer fluid consisting of a finite layer bounded above by a free surface and below by a infinite layer of greater density. Two separate cases are considered. First we consider waves which propagate along the top of a single cylinder at frequencies below the cut-off for wave propagation away fro...

introduction: quantification of epstein - barr virus (ebv) in peripheral blood mononuclear cells (pbmnc) of allogenic bone marrow transplant (bmt) recipients is important because ebv-associated posttransplant lymphoproliferative disease (ptld) can occur after transplantation due to immunosup-pression therapy. methods: to this end we chose real-time pcr using taqman probe. for the standard curve...

background: anti-mullerian hormone (amh) is constantly secreted during menstrual cycles and may offer several advantages over traditional biomarkers of ovarian reserve. objective: to assess the relationship of anti-mullerian hormone (amh) values, which are used to evaluate ovary reserves, with oocyte and embryo quality and with art outcomes in patients undergoing intra-cytoplasmic sperm injecti...

Most Salmonella control programmes are based on serological testing in the slaughterhouse. However, from a point of view of carcass contamination, it is rather the presence of Salmonella spp. in the animal at the time of slaughter that is important. The aim of this cross-sectional study was to investigate the possible discrepancies between the isolation of Salmonella spp. in the mesenteric lymp...

The one– and two– particle densities of up to four interacting electrons with spin, confined within a quasi one–dimensional “quantum dot” are calculated by numerical diagonalization. The transition from a dense homogeneous charge distribution to a dilute localized Wigner–type electron arrangement is investigated. The influence of the long range part of the Coulomb interaction is studied. When t...

The time evolution of plane waves in the presence of a 1-dimensional square quantum barrier is considered. Comparison is made between the cases of an infinite and a cut-off (shutter) initial plane wave. The difference is relevant when the results are applied to the analysis of the tunnelling regime. This work is focused on the analytical calculation of the time-evolved solution and highlights t...

We analyze the two-dimensional angular momentum-energy distribution of electrons emitted from argon by short laser pulses. We identify characteristic features of both multiphoton and tunneling ionization in the partial-wave distribution for Keldysh parameters close to unity. We observe a remarkable degree of quantum-classical correspondence in the photoinization process which becomes even more ...
