ATLASGAL -- physical parameters of dust clumps associated with 6.7 GHz methanol masers
(2019-12-01)We have constructed the largest sample of dust-associated class II 6.7 GHz methanol masers yet obtained. New measurements from the the Methanol MultiBeam (MMB) Survey were combined with the 870 $\mu$m APEX Telescope Large ... -
ATLASGAL -- Relationship between dense star forming clumps and interstellar masers
(2020-09-29)We have used catalogues from several Galactic plane surveys and dedicated observations to investigate the relationship between various maser species and Galactic star forming clumps, as identified by the ATLASGAL survey. ... -
ATLASGAL --- Molecular fingerprints of a sample of massive star forming clumps
(2019-04-21)We have conducted a 3-mm molecular-line survey towards 570 high-mass star-forming clumps, using the Mopra telescope. The sample is selected from the 10 000 clumps identified by the ATLASGAL (APEX Telescope Large Area Survey ... -
ATM automation: guidance on human technology integration
(CAA UK, 2016-03-01)Human interaction with technology and automation is a key area of interest to industry and safety regulators alike. In February 2014, a joint CAA/industry workshop considered perspectives on present and future implementation ... -
Atmospheric aerosol characterization combining multi-wavelength Raman Lidar and MAX-DOAS measurements in Gwanjgu
(SPIE, 2011)Integrated approach has been adopted at the ADvanced Environmental Research Center (ADEMRC), Gwangju Institute of Science and Technology (GIST), Korea for effective monitoring of atmospheric aerosol. Various active and ... -
Atmospheric dust charging, vertical profiles, and optical properties measured in the Arabian Peninsula during the DREAME campaign
(2010)Polarimetric observations of atmospheric Saharan dust over the Canary Islands have provided strong evidence for the presence of vertically aligned particles. The alignment was thought to be due to the electric field present ... -
Atmospheric dust modeling from meso to global scales with the online NMMB/BSC-Dust model - Part 2 : Experimental campaigns in Northern Africa
(2012)The new NMMB/BSC-Dust model is intended to provide short to medium-range weather and dust forecasts from regional to global scales. It is an online model in which the dust aerosol dynamics and physics are solved at each ... -
Atmospheric polycyclic aromatic hydrocarbons: Source attribution, emission factors and regulation
(2008)There is an increasing concern about the occurrence of polycyclic aromatic hydrocarbons (PAHs) in the environment as they are ubiquitous in ambient air and some of them are among the strongest known carcinogens. PAHs and ... -
Atmospheric Retrieval of L Dwarfs: Benchmarking Results and Characterizing the Young Planetary Mass Companion HD 106906 b in the Near-infrared
(2023-10-13)We present model constraints on the atmospheric structure of HD 106906 b, a planetary-mass companion orbiting at a ∼700 au projected separation around a 15 Myr old stellar binary, using the APOLLO retrieval code on spectral ... -
An Atmospheric Retrieval of the Brown Dwarf Gliese 229B
(2022-12-01)We present results from an atmospheric retrieval analysis of Gl 229B using the Brewster retrieval code. We find the best fit model to be cloud-free, consistent with the T dwarf retrieval work of Line et al.; Zalesky et al. ... -
ATMP-CA: Optimising Mixed-Criticality Systems Considering Criticality Arithmetic
(2021-06-06)Many safety-critical systems use criticality arithmetic, an informal practice of implementing a higher-criticality function by combining several lower-criticality redundant components or tasks. This lowers the cost of ... -
ATMP: An Adaptive Tolerance-based Mixed-criticality Protocol for Multi-core Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2018-06-08)The challenge of mixed-criticality scheduling is to keep tasks of higher criticality running in case of resource shortages caused by faults. Traditionally, mixedcriticality scheduling has focused on methods to handle faults ... -
Atomic hydrogen in the spiral galaxy NGC 3631
(1997)New high resolution, high sensitivity WSRT Hi synthesis observations of the spiral galaxy NGC 3631 are presented. In the total atomic hydrogen map, the spiral arms are well distinguished from the interarm regions, while ... -
Atomic lines in infrared spectra for ultracool dwarfs
(2004-03)We provide a set of atomic lines which are suitable for the description of ultracool dwarf spectra from 10 000 to 25 000 Å. This atomic linelist was made using both synthetic spectra calculations and existing atlases of ... -
Atomic-cascade experiment with detection of the recoil atom
(1994)Bell's inequalities cannot be violated in atomic-cascade experiments, even with ideal apparatus, due to the three-body character of the atomic decay. Here we propose a new experiment that would block this loophole by means ... -
Atomistic simulations of interfacial deformation and bonding mechanism of Pd-Cu composite metal membrane using cold gas dynamic spray process.
(2020-12)The creation of atomic structures and the study of the deformation processes through molecular dynamics simulations have shown many advantages. However, gaps associated with the development and evolution of microstructure ... -
