We present a novel compressed dynamic self-index for highly repetitive text collections. Signature encoding, an existing self-index of this type, has a large disadvantage of slow pattern search for short patterns. We obtain faster pattern search by leveraging the idea behind a truncated suffix tree (TST) to develop the first compressed dynamic self-index, called the TST-index, that supports not...
By far, many stereo-matching techniques have been successfully proposed and applied in digital aerial photogrammetry. However, due to some problems such as large parallaxes, occlusions, geometric deformations, and repetitive patterns in convergent close range images, these methods may not be applicable to the same level of success as that of aerial imagery. In order to overcome these shortcomin...
Memory formation is associated with the generation of transiently stable neuronal assemblies. In hippocampal networks, such groups of functionally coupled neurons express highly ordered spatiotemporal activity patterns which are coordinated by local network oscillations. One of these patterns, sharp wave-ripple complexes (SPW-R), repetitively activates previously established groups of memory-en...
BACKGROUND The mechanisms by which persistent atrial fibrillation (AF) terminates via localized ablation are not well understood. To address the hypothesis that sites where localized ablation terminates persistent AF have characteristics identifiable with activation mapping during AF, we systematically examined activation patterns acquired only in cases of unequivocal termination by ablation. ...
Human Activity Recognition (HAR) has been widely addressed by deep learning techniques. However, most prior research applied a general unique approach (signal processing and learning) to deal with different human activities including postures gestures. These types of activity typically have highly diverse motion characteristics, which could be captured wearable sensors placed on the user’s body...
Objectives : The aim of the present study was to investigate the predictive role of emotional dysregulation, metacognitive beliefs, intolerance of uncertainty and experiential avoidance in repetitive negative thinking. Method: In current correlational study, 510 students of Tehran University completed Repetitive Negative Thought Questionnaire (RNTQ), Difficulties in Emotion Regulation Scale (...
Microsatellites are repetitive regions of DNA which account for a highly significant amount of eukaryotic genomes. They are used as genetic markers and have various uses in the study of natural evolution and phylogeny. However, very little is known about the molecular biology mechanisms which produce microsatellites and even less is known about how and why different kinds of microsatellites occ...
Autism Spectrum Disorder (ASD) encompasses a highly variable set of neurodevelopmental disorders with early onset and non-degenerative pattern. According to the World Health Organization's International Classification Diseases (11th Revision), ICD-11, ASD is characterized as “persistent deficits in ability initiate sustain reciprocal social interaction communication, by range restricted, repeti...
Background: Thinking about the future is an integral component of human cognition ability to creatively imagine of possible future events, called future thinking that in recent years much attention in the different field of psychology (cognitive, neuropsychological, clinical, developmental) has attracted. This paper aim to investigate Future Thinking in Children with Autism Spectrum Disorders h...
DNA methylation of CpGs located in two types of repetitive elements-LINE1 (L1) and Alu-is used to assess "global" changes in DNA methylation in studies of human disease and environmental exposure. L1 and Alu contribute close to 30% of all base pairs in the human genome and transposition of repetitive elements is repressed through DNA methylation. Few studies have investigated whether repetitive...
