Eighty-eight patients with possible ankylosing spondylitis (AS) were selected for this followup study. They showed normal or at most suspicious radiographic findings of the sacroiliac joints. After 5 years' followup, 24, and after 10 years 32 patients (59% of the 54 finally available, 36% of the 88 original patients) had definite AS. In 12 individuals, AS… (More)
PURPOSE To present an interim analysis of the trial comparing two neoadjuvant therapies for unresectable rectal cancer. METHODS Patients with fixed cT3 or cT4 or locally recurrent rectal cancer without distant metastases were randomized to either 5 × 5 Gy and 3 courses of FOLFOX4 (schedule I) or 50.4 Gy delivered in 28 fractions given simultaneously with… (More)
In the context of non-commutative IL p spaces we discuss the conditions for existence and ergodicity of translation invariant stochastic spin ip and diiusion dynamics for quantum spin systems with nite range interactions on a lattice.
A set of early diagnostic (ED) criteria comprising clinical data, ESR, radiological spinal signs, and the risk factor HLA B27 was evaluated after 5 and 10 years in a follow-up of 54 patients with an initial diagnosis of possible ankylosing spondylitis (AS). After 10 years 32 patients (59%) had developed definite AS according to the New York criteria, 10… (More)
We shortly review the progress in the domain of deterministic chaos for quantum dynamical systems. With the appropriately extended definition of quantum Lyapunov exponent we analyze various quantum dynamical maps. It is argued that, within Quantum Mechanics, irregular evolution for properly chosen observables can coexist with regular and predictable… (More)
We present a discussion on local quantum correlations and their relations with entanglement. We prove that vanishing coefficient of quantum correlations implies separability. The new results on locally decomposable maps which we obtain in the course of proof also seem to be of independent interest.
We present a general description of separable states in Quantum Mechanics. In particular, our result gives an easy proof that inseparabitity (or entan-glement) is a pure quantum (noncommutative) notion. This implies that distinction between separability and inseparabitity has sense only for composite systems consisting of pure quantum subsystems. Moreover,… (More)
some old and new problems. Abstract. We outline a new approach to the characterization as well as to the classification of positive maps. This approach is based on the facial structures of the set of states and of the cone of positive maps. In particular, the equivalence between Schroedinger's and Heisenberg's pictures is reviewed in this more general… (More)
AIMS AND BACKGROUND Minimally invasive biopsy should be a standard practice in the non-operative diagnosis of breast lesions that are suspicious for or highly suggestive of malignancy. The aim of this study was to compare the procedure duration time for different methods of minimally invasive image-guided vacuum-assisted breast biopsy (VABB). METHODS Six… (More)
