Butterfly effect and spatial structure of information spreading in a chaotic cellular automaton
(2021-03-17)
Inspired by recent developments in the study of chaos in many-body systems, we construct a measure of local information spreading for a stochastic cellular automaton in the form of a spatiotemporally resolved Hamming ...
Building a model: Developing genomic resources for common milkweed (Asclepias syriaca) with low coverage genome sequencing
(BioMed Central, 2011-05-04)
Background: Milkweeds (Asclepias L.) have been extensively investigated in diverse areas of evolutionary biology and ecology; however, there are few genetic resources available to facilitate and compliment these studies. ...
Growth phase and temperature influence promoter activity, transcript abundance, and protein stability during biosynthesis of the Pseudomonas syringae phytotoxin coronatine
(American Society for Microbiology, 1998-03)
The plant-pathogenic bacterium Pseudomonas syringae pv. glycinea PG4180.N9 synthesizes high levels of the polyketide phytotoxin coronatine (COR) at 18°C, whereas no detectable toxin is produced at 28°C. Previously, we ...
miR-27b inhibits fibroblast activation via targeting TGFB signaling pathway
(BioMed Central, 2017-01-17)
Background: MicroRNAs are a group of small RNAs that regulate gene expression at the posttranscriptional level. They regulate almost every aspect of cellular processes. In this study, we investigated whether miR-27b regulates ...
Greater neural adaptations following high- vs. low-load resistance training
(Frontiers Media, 2017-05-29)
We examined the neuromuscular adaptations following 3 and 6 weeks of 80 vs. 30% one repetition maximum (1RM) resistance training to failure in the leg extensors. Twenty-six men (age = 23.1 +/= 4.7 years) were randomly ...
Characterization and transcriptional analysis of the gene cluster for coronafacic acid, the polyketide component of the phytotoxin coronatine
(American Society for Microbiology, 1995-11)
Coronafacic acid (CFA), the polyketide component of the phytotoxin coronatine (COR), is activated and coupled to coronamic acid via amide bond formation, a biosynthetic step presumably catalyzed by the CFA ligase (cfl) ...
Bacterial community structure and diversity in a century-old manure-treated agroecosystem
(American Society for Microbiology, 2004-10)
Changes in soil microbial community structure and diversity may reflect environmental impact. We examined 16S rRNA gene fingerprints of bacterial communities in six agroecosystems by PCR amplification and denaturing gradient ...
Looking at the label and beyond: The effects of calorie labels, health consciousness, and demographics on caloric intake in restaurants
(BioMed Central, 2013-02-08)
Background: Recent legislation has required calorie labels on restaurant menus as a means of improving Americans' health. Despite the growing research in this area, no consensus has been reached on the effectiveness of ...
Eu-doped CaF2 grown on Si(100) substrates by molecular beam epitaxy
(AIP Publishing, 1995-09-25)
Eu is incorporated into CaF2 films grown on Si(100) by molecular beam epitaxy using elemental Eu evaporation. Eu doping as high as 4.05 at. % does not significantly degrade the surface morphology, indicating a relatively ...
Evidence for phage-mediated gene transfer among Pseudomonas aeruginosa strains on the phylloplane
(American Society for Microbiology, 1994-02)
As the use of genetically engineered microorganisms for agricultural tasks becomes more frequent, the ability of bacteria to exchange genetic material in the agricultural setting must be assessed. Transduction (bacterial ...
