The orbital periods of aa dor and ny vir
(Oxford University Press, 2011)
New timings of eclipses made between 2000 and 2010 are presented for two binary systems
with hot subdwarf primary stars. In the case of AA Dor, an sdOB star with a very cool
secondary, the period is found to be constant ...
Identifying multiple periodicities in sparse photon event time series
(Oxford University Press, 2016)
The data considered are event times (e.g. photon arrival times, or the occurrence of sharp
pulses). The source is multiperiodic, or the data could be multiperiodic because several unresolved sources contribute to the time ...
Hall measurements on carbon nanotube paper modified with electroless deposited platinum
(Springer, 2010)
Carbon nanotube paper, sometimes referred to
as bucky paper, is a random arrangement of carbon nanotubes meshed into a single robust structure, which can be
manipulated with relative ease. Multi-walled carbon
nanotubes ...
Protein interaction networks as metric spaces: A novel perspective on distribution of hubs
(BMC, 2014)
In the post-genomic era, a central and overarching question in the analysis of protein-protein
interaction networks continues to be whether biological characteristics and functions of proteins such as lethality,
physiological ...
A critical look at the mass-metallicity-star formation rate relation in the local universe. I. An improved analysis framework and confounding systematics
(Institute of Physics Publishing, 2014)
It has been proposed that the (stellar) mass-(gas) metallicity relation of galaxies exhibits a secondary dependence on star formation rate (SFR), and that the resulting M∗-Z-SFR relation may be redshift-invariant, i.e., ...
Unpacking physics representations: Towards an appreciation of disciplinary affordance
(American Physical Society, 2014)
This theoretical article problematizes the access to disciplinary knowledge that different physics
representations have the possibility to provide; that is, their disciplinary affordances. It is argued that
historically ...
Human coronavirus NL63: A clinically important virus?
(Future Science Group, 2011)
Respiratory tract infection is a leading cause of morbidity and mortality worldwide, especially among young children. Human coronaviruses (HCoVs) have only recently been shown to cause both lower and upper respiratory tract ...
Recalibrating the Wide-field Infrared Survey Explorer (WISE) W4 Filter
(Cambridge University Press, 2014)
We present a revised effective wavelength and photometric calibration for the Wide-field Infrared Survey Explorer
W4 band, including tests of empirically motivated modifications to its pre-launch laboratory-measured ...
New formulas for the (−2) moment of the photoabsorption cross section, σ−2
(American Physical Society, 2015)
Two new formulas for the (−2) moment of the photoabsorption cross section, σ−2, have been determined,
respectively, from the 1988 photoneutron evaluation of Dietrich and Berman and a mass-dependent symmetry
energy ...
Efficient superoxide scavenging and metal immobilization in roots determines the level of tolerance to vanadium stress in two contrasting Brassica napus genotypes
(Elsevier, 2018)
Brassica napus also known as Rapeseed is a member of the Brassicaceae family which is mainly cultivated for its
oil-rich seeds. Indeed, B. napus is ranked the third-largest source of vegetable oil in the world. Brassica ...
