LINER galaxy properties and the local environment
(Oxford University Press, 2018-05)
We analyse the properties of a sample of 5560 low-ionization nuclear emission-line region (LINER) galaxies selected from SDSS-DR12 at lowred shift, for a complete range of local density environments. The host LINER galaxies ...
Sea Level Trend and Fronts in the South Atlantic Ocean
(Molecular Diversity Preservation International, 2020-06)
The understanding of the physical drivers of sea level trend is crucial on global and regional scales. In particular, little is known about the sea level trend in the South Atlantic Ocean in comparison with other parts of ...
Consecutive Queries to Assess Biological Correlation in NMR Metabolomics: Performance of Comprehensive Search of Multiplets over Typical 1D 1H NMR Database Search
(American Chemical Society, 2020-05-25)
NMR-based metabolomics requires proper identification of metabolites to draw conclusions from the system under study. Normally, multivariate data analysis is performed using 1D 1H NMR spectra, and identification of peaks ...
High pressure reveals structural determinants for globin hexacoordination: neuroglobin and myoglobin cases.
(Wiley-liss, Div John Wiley & Sons Inc, 2009-12)
The influence of pressure on the equilibrium between five-(5c) and six-coordination (6c) forms in neuroglobin (Ngb) and myoglobin (Mb) has been examined by means of molecular dynamics (MD) simulations at normal and high ...
