Sequence analysis of rDNA intergenic spacer region (IGS) as a tool for phylogenetic studies in Trichoderma spp.

open access: yes浙江大学学报. 农业与生命科学版, 2004
Different from ribosomal genes, which contain highly conserved sequences that are detected in all- organisms, the intergenic spacer of rDNA (IGS) appears to be the most rapidly-evolving spacer region.

Synchronized excitability in a network enables generation of internal neuronal sequences

open access: yeseLife, 2016
Hippocampal place field sequences are supported by sensory cues and network internal mechanisms. In contrast, sharp-wave (SPW) sequences, theta sequences, and episode field sequences are internally generated. The relationship of these sequences to memory

Ultrafast and memory-efficient alignment of short DNA sequences to the human genome

open access: yesGenome Biology, 2009
Bowtie is an ultrafast, memory-efficient alignment program for aligning short DNA sequence reads to large genomes. For the human genome, Burrows-Wheeler indexing allows Bowtie to align more than 25 million reads per CPU hour with a memory footprint of ...

Better is worse, worse is better: Reexamination of violations of dominance in intertemporal choice [PDF]

open access: yesJudgment and Decision Making, 2017
Recently, Scholten and Read (2014) found new violations of dominance in intertemporal choice. Although adding a small receipt before a delayed payment or adding a small delayed receipt after an immediate receipt makes the prospect objectively better, it ...

Learning precise spatiotemporal sequences via biophysically realistic learning rules in a modular, spiking network

open access: yeseLife, 2021
Multiple brain regions are able to learn and express temporal sequences, and this functionality is an essential component of learning and memory. We propose a substrate for such representations via a network model that learns and recalls discrete ...

Sparse Sequence-to-Sequence Models [PDF]

open access: yesProceedings of the 57th Annual Meeting of the Association for Computational Linguistics, 2019
Sequence-to-sequence models are a powerful workhorse of NLP. Most variants employ a softmax transformation in both their attention mechanism and output layer, leading to dense alignments and strictly positive output probabilities. This density is wasteful, making models less interpretable and assigning probability mass to many implausible outputs.

Integrality and the Laurent phenomenon for Somos 4 and Somos 5 sequences [PDF]

open access: yes, 2008
Somos 4 sequences are a family of sequences defined by a fourth-order quadratic recurrence relation with constant coefficients. For particular choices of the coefficients and the four initial data, such recurrences can yield sequences of integers.
