AIM Multifactorial analysis of local and lymph node recurrences in stage 0-II breast cancer treated by conservative or radical surgery. MATERIAL AND METHODS In the interval January 1, 2005-July 31, 2013, 477 breast cancer patients were assessed by imaging techniques at the Radiology Clinic of Iasi "Sf. Spiridon" Hospital and Radiology Service of the Iasi Regional Cancer Institute. Of these 22...

1 Recurrences A linear, first order recurrence is a problem of the form x(j) = a(j)x(j − 1) + y(j), x(1) = y(1) (x(0) = 0), 1 · · · · · · · −a(2) 1 · · · · · · · −a(3) 1 · · · · · · · −a(4) 1 · · · · · · · −a(5) 1 · · · · · · · −a(6) 1 · · · · · · · −a(7) 1 · · · · · · · −a(8) 1 Such a bidiagonal system of equations corresponds to the forward solution of a system Ax = y after LU–factorization o...

General solution methods for linear vector recurrences are considered; an algorithm based on partial fraction expansion is shown to be the most efficient way of solving this problem.
