Metacognitive beliefs mediate the relationship between Anxiety Sensitivity and traits of Obsessive-Compulsive Symptoms
(2020-04-26)Background: Metacognition has been shown as a key contributor to Obsessive Compulsive Disorder as well as other anxiety-related disorders, yet its role in the development and maintenance of these disorders remains unclear. ... -
Metadata Extraction and Classification of YouTube Videos Using Sentiment Analysis
(IEEE 978-1-5090, 2016-10-24)MPEG media have been widely adopted and is very successful in promoting interoperable services that deliver video to consumers on a range of devices. However, media consumption is going beyond the mere playback of a media ... -
Metagenomics approach for Polymyxa betae genome assembly enables comparative analysis towards deciphering the intracellular parasitic lifestyle of the plasmodiophorids
(2022-01-01)Genomic knowledge of the tree of life is biased to specific groups of organisms. For example, only six full genomes are currently available in the rhizaria clade. Here, we have applied metagenomic techniques enabling the ... -
Metal abundances of sdB stars

Metal Abundances of Subdwarf B Stars from SPY - a Pattern Emerges
(Astronomical Society of the Pacific, 2008)The formation of sdBs is still puzzling, as is the chemical compo- sition of their atmospheres. While helium and other light elements are depleted relative to solar values, heavy elements are highly enriched. Diffusion ... -
Metal binding characterization and conformational studies using Raman microscopy of resin-bound poly(aspartic acid)
(2007-03-01)The metal binding capacities, conditional stability constants, and secondary structure of immobilized polyaspartic acid (PLAsp) (n = 6, 20, and 30) on TentaGel resin were determined when binding Mg2+, Co2+, Cd2+, and Ni2+. ... -
Metal remediation and preconcentration using immobilized short-chain peptides composed of aspartic acid and cysteine
(2005-08)Short-chain peptides (two and seven residues) consisting of a glycine (Gly) attachment group and various combinations of cysteine (Cys) and/or aspartic acid (Asp) were synthesized by Fmoc solid phase peptide synthesis ... -
The metal rich abundance pattern - spectroscopic properties and abundances for 107 main-sequence stars
(2017-07-01)We report results from the high resolution spectral analysis of the 107 metal rich (mostly [Fe/H]$\ge$7.67 dex) target stars from the Calan-Hertfordshire Extrasolar Planet Search program observed with HARPS. Using our ... -
Metal-based nanoparticles for combating antibiotic resistance
(2021-10-05)The resistance to antibiotics in combating bacteria is a serious worldwide problem. The search for new approaches to address antibacterial resistance is therefore of crucial importance and seeking alternatives for the ... -
A metal-biased planet search
(American Institute of Physics (AIP), 2009)We have begun a metal-rich planet search project using the HARPS instrument in La Silla, Chile to target planets with a high potential to transit their host star and add to the number of bright benchmark transiting planets. ... -
Metal-Free Disordered Vertical Sub-Micron Silicon Wires Produced from Electrochemical p-Type Porous Silicon Layers
(2011)In this paper, we propose a simple, original and costless method to produce monocrystalline silicon sub-micron wires by electrochemical etching of silicon wafers. For this purpose, 30-50 Omega cm p-type silicon samples ... -
Metal-rich carbon stars in the Sagittarius dwarf spheroidal galaxy
(2009)We present spectroscopic observations from the Spitzer Space Telescope of six carbon-rich asymptotic giant branch (AGB) stars in the Sagittarius dwarf spheroidal galaxy (Sgr dSph) and two foreground Galactic carbon stars. ... -
The Metallicity and Elemental Abundance Gradients of Simulated Galaxies, and their Environmental Dependence
(2017-11-11)The internal distribution of heavy elements, in particular the radial metallicity gradient, offers insight into the merging history of galaxies. Using our cosmological, chemodynamical simulations that include both detailed ... -
The metallicity and elemental abundance maps of kinematically atypical galaxies for constraining minor merger and accretion histories
(2019-03-06)Explaining the internal distribution and motions of stars and gas in galaxies is a key aspect in understanding their evolution. In previous work we identified five well-resolved galaxies with atypical kinematics from a ... -
Metallicity and Mean Age Across M,33

Metallicity distributions of elliptical galaxies and globular cluster systems - Absorption line strength gradients in elliptical galaxies
(1999)Gradients of absorption line indices are studied and mean stellar metallicities are estimated for 46 elliptical galaxies. The mean stellar metallicities range from [[Fe/H]] similar or equal to -0.8 to +0.2 and ellipticals ... -
Metallicity effect on type Ia supernovae and galactic and cosmic chemical evolution
