Emissions of NO and NH3 from a Typical Vegetable-Land Soil after the Application of Chemical N Fertilizers in the Pearl River Delta
(PLos One, 2013-03-19)
Cropland soil is an important source of atmospheric nitric oxide (NO) and ammonia (NH3). Chinese croplands are characterized by intensive management, but limited information is available with regard to NO emissions from ...
Transient Growth Arrest in Escherichia coli Induced by Chromosome Condensation
(PLos One, 2013-12-23)
MukB is a bacterial SMC (structural maintenance of chromosome) protein that regulates the global folding of the Escherichia coli chromosome by bringing distant DNA segments together. We report that moderate overproduction ...
Similar Gene Estimates from Circular and Linear Standards in Quantitative PCR Analyses Using the Prokaryotic 16S rRNA Gene as a Model
(PLos One, 2012-12-19)
Quantitative PCR (qPCR) is one of the most widely used tools for quantifying absolute numbers of microbial gene copies in test samples. A recent publication showed that circular plasmid DNA standards grossly overestimated ...
Supersymmetry and the Prisoner of Naturalness
(2017-07-27)
In this work, I will address three concerns of supersymmetry. The first is the notion of naturalness and how much fine-tuning exists in a model. Historical measures, ∆ HS and ∆ BG , have led to an over estimate of the ...
Mannose-Binding Lectin 2 Gene and Risk of Adult Glioma
(PLos One, 2013-04-18)
Background and AimsThe immune system is likely to play a key role in the etiology of gliomas. Genetic polymorphisms in the mannose-binding lectin gene, a key activator in the lectin complement pathway, have been associated ...
The Impact of Surface Heterogeneity on Surface Flux Estimates of the Stable Boundary Layer Using Single Column Modeling
(2022-08)
The surface fluxes of momentum and heat play an important role in the evolution of the atmospheric boundary layer (ABL). Accurate representation of the fluxes in weather and climate forecasting models, especially when ...
Immunodominance of Antigenic Site B over Site A of Hemagglutinin of Recent H3N2 Influenza Viruses
(PLos One, 2012-07-25)
H3N2 influenza viruses have now circulated in the human population for 43 years since the pandemic of 1968, accumulating sequence changes in the hemagglutinin (HA) and neuraminidase (NA) that are believed to be predominantly ...
Structure and Dynamics of Amyloid-β Segmental Polymorphisms
(PLos One, 2012-07-24)
It is believed that amyloid-beta (Aβ) aggregates play a role in the pathogenesis of Alzheimer’s disease. Aβ molecules form β-sheet structures with multiple interaction sites. This polymorphism gives rise to differences in ...
