BACKGROUND/AIM Plasma cells infiltrate in the liver is a prototype lesion of autoimmune liver diseases. The possible role of plasma cells isotyping (IgM and IgG) in the liver in the diagnostic definition of autoimmune liver disease, and particularly in variant syndromes such as autoimmune cholangitis and the primary biliary cirrhosis/autoimmune hepatitis overlap syndrome, is less defined. MET...

background: knowing the rate of overlapping in results obtained from information retrieval tools is important to prevent waste of time. medical and health-related information has an outstanding place among the variety of information available on the internet. hence, this research aimed to study the rate of overlap among medical search results derived from mesh (medical subject headings) in gene...

The ratio of L- to K-shell electron captures in light nuclei is particularly sensitive to electron overlap and exchange effects. Calculations of these effects in (7)Be disagree by more than 20%. We report a measurement of the L/K ratio in (7)Be, using a cryogenic microcalorimeter which clearly separates L- and K-shell captures. The obtained L/K ratio of 0.040(6) is less than half that of existi...

Overlap in markup occurs where some markup structures do not nest, such as where the structural division of the text into lists, sections, etc., differs from the syntactic division of the text into sentences and phrases. The Multiple Annotation solution to this problem (redundant encoding in multiple forms) has many advantages: it is based on XML, the modeling of alternative annotations is poss...

Let L be a non empty loop structure. We say that L is add-left-cancelable if and only if: (Def. 1) For all elements a, b, c of L such that a + b = a + c holds b = c. We say that L is add-right-cancelable if and only if: (Def. 2) For all elements a, b, c of L such that b + a = c + a holds b = c. We say that L is add-cancelable if and only if: (Def. 3) For all elements a, b, c of L holds if a + b...

A hallmark of optimal decision making is that cues are weighted by their reliability. Previous studies have reported evidence for reliability weighting in several human perceptual decision-making tasks in which sensory noise was the only possible source of errors. Here we use a target detection task to test whether optimality generalizes to situations where stimulus ambiguity is an additional s...

Objective: To assess the performance of morphometric parameters calculated from breast lesion contours at ultrasonography, in the quantification of morphological features and in the distinction among BI-RADS categories 2, 3, 4 and 5. Materials and Methods: The present casuistry included 40 cases, with orthogonal imaging of patients submitted to surgery. Based on the lesions segmentation, the fo...

in order to determine the effect of valsalva maneuver and head rotation on the internal jugular vein (ijv) diameter and cross-sectional area and overlap with the carotid artery (ca) and find the best technique for safe cannulation of the ijv and decrease the risk of ca puncture, the diameter of both the ijv and the ca and percentage of overlap between the two vessels and cross-sectional area of...

Little is known about the distribution and structure of satisfying assignments of large K-CNF for-mulae. One interesting feature, observed by numerical simulations, is that for K 2, there is a sharp transition from a phase in which almost all formulae are satissable to a phase in which almost all formulae are un-satissable, as the ratio = M N goes through some critical value. So far there is no...
