One hope when using non-elitism in evolutionary computation is that the ability to abandon current-best solution aids leaving local optima. To improve our understanding of this mechanism, we perform a rigorous runtime analysis basic non-elitist algorithm (EA), $$(\mu ,\lambda )$$ EA, on most benchmark function with optimum, jump function. We prove for all reasonable values parameters and proble...

Splenic arteriovenous fistulas (AVFs) are rare lesions. Herein, we report a 40-year-old man with portal hypertension secondary to splenic AVF, which was primarily diagnosed by color Duplex sonography. Sonography revealed a non-pulsatile, cyst-like mass at the splenic hilum with an unusual comma-shaped extension. In color duplex sonography, complete color fill-in of the lesion with the character...

Scenarios have been already used for designing and evaluating ontology-based tools. For example, the so-called “motivating scenarios” are a core component of the TOVE ontological engineering method elaborated by Grüninger and Fox (1995; Uschold and Grüninger, 1996). We ourselves used a “scenario approach” for designing and evaluating CoMMA, a corporate memory computer platform based on ontologi...

Recently, an interaction between the mathematical discipline of combinatorics on words and musical scale theory has led to various interesting results. So far, the focus was mainly on scales generated by a single interval. The paper proposes an extension of word scale theory to tone systems of higher dimensions, i.e. generated by more than one interval. It is shown that the number of specific v...

In the quest for an elegant formulation of the notion of “polycategory” we develop a more symmetric counterpart to Burroni’s notion of “T -category”, where T is a cartesian monad on a category X with pullbacks. Our approach involves two such monads, S and T , that are linked by a suitable generalization of a distributive law in the sense of Beck. This takes the form of a span TS ω ST in the fun...

We first prove an extremal property of the infinite Fibonacci∗ word f : the family of the palindromic prefixes {hn | n ≥ 6} of f is not only a circular code but “almost” a comma-free one (see Prop. 12 in Sect. 4). We also extend to a more general situation the notion of a necklace introduced for the study of trinucleotides codes on the genetic alphabet, and we present a hierarchy relating two i...

I met Bernard L. Diamond when he served as one of my examiners for the American Board of Forensic Psychiatry in February 1979. Following that, we became good friends although we lived on opposite coasts. Soon after, we happened to meet in an airport. He said he was trying to determine the significance of a particular comma in a 16th century law book. It turned out to be in the paragraph in Lamb...
