Long-range interactions in sequences of human behavior
نویسنده
چکیده
Measures derived from the thermodynamic formalism for dynamical systems are applied to human behavior to determine the degree of interaction within sequences of choices. Sequences of 500 binary choices generated by 22 human subjects are analyzed using autocorrelation and mutual information functions, as well as the fluctuation spectrum of local dynamical entropies or local spatial scaling exponents. The main results are as follows: ~1! choices generated by the subjects are interdependent on short, midrange, and large scales relative to the 500 choices generated in the paradigm; ~2! human behavior is characterized by large fluctuations of dynamical and geometrical choice characteristics; and ~3! these geometric and dynamical characteristics can be related to a few competing principles. @S1063-651X~97!01203-8#

Phylogenetic Analysis of Three Long Non-coding RNA Genes: AK082072, AK043754 and AK082467
Now, it is clear that protein is just one of the most functional products produced by the eukaryotic genome. Indeed, a major part of the human genome is transcribed to non-coding sequences than to the coding sequence of the protein. In this study, we selected three long non-coding RNAs namely AK082072, AK043754 and AK082467 which show brain expression and local region conservation among vertebr...
متن کاملP87: The Role of the Long Non-Coding RNA Sequences (LncRNAs) in Neurological Disorders
Precise interpretation of the transcriptome sequences in the several species showed that the major part of genome has been transcribed; however, just a few amounts of the transcription sequences have open-reading frames which are conversed during the evolution. So, it is unlikely that many of the transcribed sequences code the proteins. Among the all human non-coding transcripts, at least 10000...
متن کاملLong non-coding RNAs and their significance in human diseases
Protein-coding genes account for only a small fraction of the human genome and most of the genomic sequences are transcriptionally silent, but recent observations indicate significant functional elements, including non-coding protein transcripts in the human genome. Long non-coding RNAs (lncRNAs) have been defined as transcripts of >200 nucleotides without protein-coding capacity that perform t...
متن کاملUsing Implicit/Explicit Salvation Models to Theoretical Study Tautomerism in 7H-purine-2, 6-diamine
A theoretical study at the B3LYP/6-31++G(d,p) level was performed on the tatumerization of 7H-purine-2, 6-diamine into 9H-purine-2, 6-diamine. Such a tautomerism can take place via three different pathways namely A, B, and C. The energetic results associated with the gas phase reveal that pathways A, B, and C display a very high activation Gibbs free energy of 45.1, 68.6 and 48.9 kcal/mol, resp...
متن کاملRoles of Chromatin insulators in gene regulation and diseases
With advances in genetic science, the dynamic structure of eukaryotic genome is considered as basis of gene expression regulation. Long-distance communication between regulatory elements and target promoters is critical and the mechanisms responsible for this connection are just starting to emerge. Chromatin insulators are key determinants of proper gene regulation and precise organization of c...
