Fast Food and Deprivation in Nova Scotia [PDF]

open access: yesCanadian Journal of Public Health, 2009
To examine the relationship between density of fast food restaurants and measures of social and material deprivation at the community level in Nova Scotia, Canada.Census information on population and key variables required for the calculation of deprivation indices were obtained for 266 communities in Nova Scotia.

Quark nova model for fast radio bursts [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2016
FRBs are puzzling, millisecond, energetic radio transients with no discernible source; observations show no counterparts in other frequency bands. The birth of a quark star from a parent neutron star experiencing a quark nova - previously thought undetectable when born in isolation - provides a natural explanation for the emission characteristics of ...

A 9 Month Hubble Space Telescope Near-UV Survey of M87. I. Light and Color Curves of 94 Novae, and a Redetermination of the Nova Rate

open access: yesThe Astrophysical Journal Supplement Series, 2023
M87 has been monitored with a cadence of 5 days over a span of 9 months through the near-ultraviolet (NUV; F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3) of the Hubble Space Telescope.

Near-infrared and optical studies of the fast nova V4643 Sgr (Nova Sagittarii 2001) [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2006
V4643 Sagittarii or Nova Sagittarii 2001 was discovered in outburst at 7.7 mag. on 2001 February 24. Here, we present near-infrared results of this fast classical nova obtained in the early decline phase in 2001 March followed by optical observations about one month later.

Nova remnants … the fast siblings of planetary nebulae

open access: yesProceedings of the International Astronomical Union, 2023
AbstractClassical and recurrent novae are luminous eruptions taking place in binary star systems in which a white dwarf accretes material from a non-degenerate stellar companion. After the nova event, a shell of gas is expelled and expands into the surrounding environment at hundreds to thousands of km s−1.

A Multiwavelength Light-curve Analysis of the Classical Nova YZ Ret: An Extension of the Universal Decline Law to the Nebular Phase

open access: yesThe Astrophysical Journal, 2023
YZ Ret is the first X-ray flash detected classical nova, and is also observed in optical, X-ray, and gamma-ray. We propose a comprehensive model that explains the observational properties.

BRAT-nova: fast and accurate mapping of bisulfite-treated reads [PDF]

open access: yesBioinformatics, 2016
Abstract Summary: In response to increasing amounts of sequencing data, faster and faster aligners need to become available. Here, we introduce BRAT-nova, a completely rewritten and improved implementation of the mapping tool BRAT-BW for bisulfite-treated reads (BS-Seq). BRAT-nova is very fast and accurate. On the human genome, BRAT-nova
