Critical exponents for the 3D O(n)–symmetric model with n > 3 are estimated on the base of six–loop renormalisation–group (RG) expansions. Simple Padé–Borel technique is used for resummation of RG series and Padé approximants [L/1] are shown to give rather good numerical results for all calculated quantities. For large n, the fixed point location gc and critical exponents are also determined di...

The presence of comorbidity becomes increasingly important for its prognostic effect on survival in breast cancer patients with advancing age. This study aimed to evaluate the role of comorbidities including hypertension as a mediator of disparity in survival after metastasis diagnosis between younger (≤51 years) and older (>51 years) patients. A total of 553 patients 26-88 years of age with br...

This article aims to define the conceptual field of jouissance in Lacanian theory, and put forth the hypothesis of a relationship between certain neurophysiological mechanisms and specific clinical phenomena where jouissance is "kindled" and outside the control of the symbolic process. First, the author briefly introduces Lacan's notion of jouissance and the way it draws on Freud's theorization...

The eigenvalues of the isotropic magnetic interaction system extraction from Internal Field Approximation (IFA) q e computed. on the basis of RKKY for the complicated magnetic behaviour of Gd, X system X= (Au , Pt , Al , In ) as well as Gd. From the strength and slope of eigenvalue curves in different ranges of interaction the strength and sharpness of the magnetic transition can be suggest...

We construct a Hamiltonian which in a scaling limit becomes equivalent to one that can be diagonalized by a Bogoliubov transformation. There may appear simultaneously a mean-field and a superconducting phase. They influence each other in a complicated way. For instance, an attractive mean field may stimulate the superconducting phase and a repulsive one may destroy it.
