On the automaticity of the Hankel determinants of a family of automatic sequences [PDF]
Theoretical Computer Science, 2019 Hankel determinants and automatic sequences are two classical subjects widely studied in Mathematics and Theoretical Computer Science. However, these two topics were considered totally independently, until in 1998, when Allouche, Peyrière, Wen and Wen proved that all the Hankel determinants of the Thue-Morse sequence are nonzero.

Repetition factorization of automatic sequences
CoRR, 2023 Following Inoue et al., we define a word to be a repetition if it is a (fractional) power of exponent at least 2. A word has a repetition factorization if it is the product of repetitions. We study repetition factorizations in several (generalized) automatic sequences, including the infinite Fibonacci word, the Thue-Morse word, paperfolding words, and ...

Virology Journal, 2008 RNA recombination is one of the two major factors that create RNA genome variability. Assessing its incidence in plant RNA viruses helps understand the formation of new isolates and evaluate the effectiveness of crop protection strategies.

Frobenius Numbers and Automatic Sequences
CoRR, 2021 The Frobenius number $g(S)$ of a set $S$ of non-negative integers with $\gcd 1$ is the largest integer not expressible as a linear combination of elements of $S$. Given a sequence ${\bf s} = (s_i)_{i \geq 0}$, we can define the associated sequence $G_{\bf s} (i) = g(\{ s_i,s_{i+1},\ldots \})$. In this paper we compute $G_{\bf s} (i)$ for some classical

Emotion Recognition from Skeletal Movements
Entropy, 2019 Automatic emotion recognition has become an important trend in many artificial intelligence (AI) based applications and has been widely explored in recent years. Most research in the area of automated emotion recognition is based on facial expressions or

Machine learning can differentiate venom toxins from other proteins having non-toxic physiological functions [PDF]
PeerJ Computer Science, 2016 Ascribing function to sequence in the absence of biological data is an ongoing challenge in bioinformatics. Differentiating the toxins of venomous animals from homologues having other physiological functions is particularly problematic as there are no ...

A generalization of automatic sequences
Theoretical Computer Science, 1988 The paper deals with sequences of strings from a word semigroup \(A^*\) and gives a connection between the following ideas: (1) generalized systems of enumeration, (2) locally catenative formulas, (3) automata with generalized digits as inputs and (4) fixed points of (certain) morphisms.

Recognising facial expressions in video sequences
, 2008 We introduce a system that processes a sequence of images of a front-facing human face and recognises a set of facial expressions. We use an efficient appearance-based face tracker to locate the face in the image sequence and estimate the deformation of ...
