Defect Effect of Bi-infinite Words in the Two-element Case [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
Let X be a two-element set of words over a finite alphabet. If a bi-infinite word possesses two X-factorizations which are not shiftequivalent, then the primitive roots of the words in X are conjugates.

Archaizing neologisms of Platon Lukashevich in the early works of Alexei Kruchenykh [PDF]

open access: yesRhema. Рема, 2021
The article discusses the genesis of Alexei Kruchenykh’s manner of writing. To achieve the goal, for the first time, a lexical comparison of the futurist poetic texts and Platon Lukashevich’s book “Charomutie, or sacred language of magicians, Magi and ...

Automatic detection of semantic primitives using optimization based on genetic algorithm [PDF]

open access: yesPeerJ Computer Science, 2023
In this article, we propose a method for the automatic retrieval of a set of semantic primitive words from an explanatory dictionary and a novel evaluation procedure for the obtained set of primitives.

A Classification of Trapezoidal Words [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
Trapezoidal words are finite words having at most n+1 distinct factors of length n, for every n>=0. They encompass finite Sturmian words. We distinguish trapezoidal words into two disjoint subsets: open and closed trapezoidal words. A trapezoidal word

A Note on the Primitive Roots and the Golomb Conjecture

open access: yesJournal of Mathematics, 2021
In this paper, we use the elementary methods and the estimates for character sums to prove the following conclusion. Let p be a prime large enough.

Word posets, with applications to Coxeter groups [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
We discuss the theory of certain partially ordered sets that capture the structure of commutation classes of words in monoids. As a first application, it follows readily that counting words in commutation classes is #P-complete.

On the decidability and complexity of Metric Temporal Logic over finite words [PDF]

open access: yesLogical Methods in Computer Science, 2007
Metric Temporal Logic (MTL) is a prominent specification formalism for real-time systems. In this paper, we show that the satisfiability problem for MTL over finite timed words is decidable, with non-primitive recursive complexity.

Analysis of data types in "Comenius Logo"

open access: yesLietuvos Matematikos Rinkinys, 1999
This paper deals with two standpoint of data types in "Comenius Logo". The traditional one considers three kinds of "Comenius Logo" data structures: words, images, and lists. The modern standpoint pick out three mechanisms of forming and exploring data:

Spinal Metastases of Supratentorial Glioblastoma with Primitive Neuronal Component

open access: yesWorld Neurosurgery: X, 2019
Background: Glioblastoma multiforme with a primitive neuronal component is a rare entity, with few cases reported in the literature. Case Description: A patient who had a supratentorial glioblastoma multiforme with a primitive neuronal component ...
