A Criterion for Non-automaticity of Sequences
We give a criterion for a sequence (an)n≥1 to be non-automatic, i.e., for when there does not exist a finite automaton generating this sequence. As application we generalize a result of Yazdani on the non-automaticity of multiplicative sequences.
متن کاملA Generic Criterion for Gene Recognitions in Genomic Sequences.
In this paper, we evaluated the complexity and accuracy of dicodon model for gene finding using Hidden Markov Model with Self-Identification Learning. We used five different models as competitors with smaller parametric space than the dicodon model. Our evaluation result shows that the dicodon model outperforms other competitors in terms of sensitivity as well as specificity. This result indica...
متن کاملTopological Mixing and Hypercyclicity Criterion for Sequences of Operators
For a sequence {Tn} of continuous linear operators on a separable Fréchet space X, we discuss necessary conditions and sufficient conditions for {Tn} to be topologically mixing, and the relations between topological mixing and the Hypercyclicity Criterion. Among them are: 1) topological mixing is equivalent to being hereditarily densely hypercyclic; 2) the Hypercyclicity Criterion with respect ...
متن کاملA Criterion for the Log-Convexity of Combinatorial Sequences
Recently, Došlić, and Liu and Wang developed techniques for dealing with the log-convexity of sequences. In this paper, we present a criterion for the log-convexity of some combinatorial sequences. In order to prove the log-convexity of a sequence satisfying a three-term recurrence, by our method, it suffices to compute a constant number of terms at the beginning of the sequence. For example, i...
متن کاملNew empirical failure criterion for shale
A new failure criterion was presented to predict the ultimate strength of shale under the triaxial and polyaxial state of stress. A database containing 93 datasets was obtained from the results of the uniaxial, triaxial, polyaxial compressive tests, an indirect tensile test was collected from reliable references, and this test was carried out on the shale samples taken from the southwestern oil...
