The focus of this thesis is on the study of repetitive structures in words, a central topic in the area of combinatorics on words. The results presented in the thesis at hand are meant to extend and enrich the existing theory concerning the appearance and absence of such structures. In the first part we examine whether these structures necessarily appear in infinite words over a finite alphabet...
Current research demonstrates increased learning rates in differential learning (DL) compared to repetitive training. To date, little is known on the underlying neurophysiological processes in DL that contribute to superior performance over repetitive practice. In the present study, we measured electroencephalographic (EEG) brain activation patterns after DL and repetitive badminton serve train...
The basic principles of chromosomal organization in eukaryotic cells remain elusive. Current mainstream research efforts largely concentrate on searching for critical packaging proteins involved in organizing chromosomes. I have taken a different perspective, by considering the role of genomic information in chromatins. In particular, I put forward the concept that repetitive DNA elements are k...
Autism Spectrum Disorder (ASD) is characterized by deficits in communication and social interaction, restricted, repetitive movements behavioural patterns. In this case report we would like to describe a worsening symptomatology of patient affected ASD following SARS-CoV-2 infection
Many man-made and natural structures consist of similar elements arranged in regular patterns. In this paper we present an unsupervised approach for discovering and reasoning on repetitive patterns of objects in a single image. We propose an unsupervised detection technique based on a voting scheme of image descriptors. We then introduce the concept of latticelets: minimal sets of arcs that gen...
We extend our analysis of repetitive patterns found in genetic programming genomes to tree based GP. As in linear GP, repetitive patterns are present in large numbers. Size fair crossover limits bloat in automatic programming, preventing the evolution of recurring motifs. We examine these complex properties in detail: e.g. using depth v. size Catalan binary tree shape plots, subgraph and subtre...
BACKGROUND Restricted and repetitive behaviors are defining features of autism spectrum disorder (ASD). Under revised diagnostic criteria for ASD, this behavioral domain now includes atypical responses to sensory stimuli. To date, little is known about the neural circuitry underlying these features of ASD early in life. METHODS Longitudinal diffusion tensor imaging data were collected from 21...
in this study, the authors reported a case of woman with severe compulsion who became pregnant during the repetitive transcranial magnetic stimulation. we carried out repetitive transcranial magnetic stimulation and behavior therapy simultaneously after repeated medications' refraction. the patient received 20 sessions 1 hz repetitive transcranial magnetic stimulation in right dorsolateral...
A dictionary-based approach for extracting repetitive patterns in music aimed at music feature extraction and indexing for audio database management is proposed. In this system, segmentation is achieved based on the tempo information and a music score is decomposed into bars. Each bar is indexed and a bar index table is built. Then, an adaptive dictionary-based compression algorithm known as Le...
Repetitive microsatellites mutate at relatively high rates and may contribute to the rapid evolution of species-typical traits. We show that individual alleles of a repetitive polymorphic microsatellite in the 5' region of the prairie vole vasopressin 1a receptor (avpr1a) gene modify gene expression in vitro. In vivo, we observe that this regulatory polymorphism predicts both individual differe...
