OBJECTIVE US is a promising tool in evaluating RA synovitis, but abnormal US findings have been reported in small subsets of normal joints in healthy subjects. This study aimed to systematically assess greyscale US (GSUS) and power Doppler US (PDUS) findings in 40 peripheral joints-the 28-joint DAS (DAS28) set, ankles and MTP joints-in healthy subjects. A composite score of abnormal US findings...

We continue the investigation of the path-connected geometry on the Cantor space and the related notions of dilution and compressibility described in [1]. These ideas are closely related to the notions of effective Hausdorff and packing dimensions of reals, and we argue that this geometry provides the natural context in which to study them. In particular we show that every regular real can be m...

Let SCRc = {σ ∈ 2n : K(σ) ≥ n + K(n) − c}, where K denotes prefix-free Kolmogorov complexity. These are the strings with essentially maximal prefix-free complexity. We prove that SCRc is not a Π1 set for sufficiently large c. This implies Solovay’s result that strings with maximal plain Kolmogorov complexity need not have maximal prefix-free Kolmogorov complexity, even up to a constant. We show...

The purpose of this paper is to investigate the asymptotic behavior of positive solutions of nonautonomous and random competitive Kolmogorov systems via the skew-product flows approach. It is shown that there exists an unordered carrying simplex which attracts all nontrivial positive orbits of the skewproduct flow associated with a nonautonomous (random) competitive Kolmogorov system. © 2008 El...

Intuitively, patterns of numerical sequences are often interpreted as formulas. However, we have observed earlier that such an intuition is too naive. Numerical Kolmogorov complexity theory is further developed. Based on these new formulations, a sequence is random if There is no patterns that are simpler than the complexity of data.

Aim: Evaluating pituitary gland dimensions in varying age ranges and genders is essential for determining average values MRI examinations. Therefore, the main objective of our study to create normative data size Turkish population.
 Material Method: Anteroposterior (AP), transverse (TR), craniocaudal (CC) glands 200 patients over 18 years age, who underwent Brain examination centre between...

In analogy of classical Kolmogorov complexity we define a notion of the algorithmic information in bits contained in any one of continuously many pure quantum states: quantum Kolmogorov complexity. Classical Kolmogorov complexity coincides with the new quantum Kolmogorov complexity restricted to the classical domain. Quantum Kolmogorov complexity is upper bounded and can be effectively approxim...
