DYNAMIC ONTOLOGIES THAT ENCODE AND MANAGE RELEVANCE IN CONTEXT AWARE SYSTEMS
… is users who wish to use generic systems must encode relevance across ontological models, filters, and newly created external software with each re-use in order to manage context manipulation at run time. Through the design and implementation of Rover3, while leveraging the concept of an …

Effects of preschoolers' gender and prosocial behavior on their abilities to decode and encode facial affect
… and gender on their abilities to decode and encode facial expressions. Four hypotheses were addressed in this study. The first hypothesis predicted a positive correlation between decoding abilities and pro social behavior of preschool-level children. The second hypothesis made a similar …

Sentiment analysis of product reviews using coupled sentence-bidirectional encode representations from transformers and topic modeling
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-09-16 without embargo terms

Molecular cloning, immunolocalization, and transgenic expression in yeast and tobacco of three cDNAs that encode sugar transporters in sugar beet
Sugar transporter genes from sugar beet have been cloned as a first step in understanding their contribution to assimilate partitioning. Two cloning strategies were attempted. One was functional complementation of a yeast mutant with a sugar beet cDNA library constructed in a yeast expression …

Brain-wide representations of behavior spanning multiple timescales and states in C. elegans
… its brain. However, how neurons across the brain encode behavior and how this is impacted by state is poorly understood. We recorded brain-wide activity and the diverse motor programs of freely-moving C. elegans and built probabilistic models that explain how each neuron encodes quantitative …

Identification of proteins interacting with lupin and Arabidopsis tRNA nucleotidyltransferases
… mitochondrial and chloroplast genomes all encode tRNAs. Therefore, although tRNA nucleotidyltransferase is synthesized in the cytosol, it must function in multiple organelles and be targeted to these locations from its site of synthesis. In general, while much is known about the targeting …

The Flexible Mind of a Worm: the atlas of brain-wide representations of behavior in C. elegans
… outputs. However, how neurons across the brain encode quantitative features of an animal’s behavior remains largely unknown. In this work, we built a new system to record and extract brain-wide activity in freely-behaving C. elegans. We built non-linear probabilistic models to explain how …

Encoding of periodic skin stimuli by spinal dorsal horn neurons
… that for most cells, firing rate is adequate to encode stimuli at 50 Hz and below, but insufficient at 100 and 200Hz. A small number of neurons were able to encode stimulus frequencies of 50Hz and higher in their firing rates. Periodicity is present in most cell discharges at all frequencies. …

Comparative biochemistry and genetic analysis of nucleoside hydrolase in Escherichia coli, Pseudomonas aeruginosa, and Pseudomonas fluorescens.
… In E. coli, three genes were found that encode homologues of several known nucleoside hydrolases in protozoa. All three genes (designated yaaF, yeiK, and ybeK) were amplified by PCR and cloned. Two of the gene products (yeiK and ybeK) encode pyrimidine-specific nucleoside hydrolases, …

Neural Dynamics in the Basal Ganglia Underlying Birdsong Practice and Performance
… performance, favoring exploitation. How neurons encode and dynamically regulate motor variability across practice and performance states remains unknown. Songbirds sing more variable songs when practicing alone and highly stereotyped songs when performing to a female, providing a powerful system …

A hybrid system for video compression based on H.264 and JPEG2000
… and H.264 standards. JPEG2000 is used to encode the I-frames, while H.264 is used to encode the P-frames. The goal of this thesis is to evaluate the performance of this hybrid system. The system is evaluated using a set of eight test video sequences, which cover a range of resolutions (CIF …

Biochemical and Genetic Characterization of Reduced Phosphorus Metabolism in Pseudomonas Stutzeri WM88
… source of P. This process requires two operons encoded by htxABCDEFGHIJKLMN and ptxABCDE, which are separated by ca. 15 kbp. Sequence analysis of the htx operon suggests that htrA encodes a novel member of the 2-oxoglutarate dependent dioxygenase enzyme family, htxBCDE encode a binding protein …

The role of arabidopsis UV-resistance locus 8 protein in regulating photosynthetic competence
… (UV-B) radiation. Some of these genes encode chloroplast proteins including the RNA polymerase sigma factor, sigma 5 (SIG5) and one of the Early Light Induced Proteins in Arabidopsis thaliana (ELIP1). According to this discovery, UVR8 had been proposed to be involved in regulating …

The role of cortical layer six in the perception and laminar representation of sensory change
… patterns. In awake mice, layer 4 neurons encode current stimulus deviations with a predominantly monotonic, faithful encoding, while neurons in layer 2/3 encode history dependent change signals with heterogeneous receptive fields. Corticothalamic (CT) cells in Layer 6 respond sparsely, but …
