We propose an ultrametric breaking of replica symmetry for diluted spin glasses in the framework of RandomMulti-Overlap Structures (RaMOSt). Such proposal is closer to the Parisi theory for non-diluted spin glasses than the current theory based on the iterative approach. Our approach permits to formulate an ansatz according to which the Broken Replica Symmetry trial function depends on a set of...

This article tries to give some guidelines to optimize the 3G-2G and 3G-3G handovers, from the extracted experience of a real network in development. The purpose of the adjustment of the 3G-2G handover parameters is to offer the users with dual terminals a quality, equal or better than those ones with only 2G terminals, where in general, the 3G coverage is minor that the 2G one. On the other ha...

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...

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...
