UBV photometry of the open clusters NGC 6604 and NGC 6704

Forbes, Doug; DuPuy, David L. (American Astronomical Society, 1978-03)

The open clusters NGC 6604 and NGC 6704 have been studied with UBV photoelectric and photographic photometry, resulting in improved distance and color-magnitude diagrams. NGC 6604 is a very young (~4x 10 [supercript 6] yr) ...

Uniformly dissociated graphs

Brešar, Boštjan; Hartnell, Bert L.; Rall, Douglas F. (University of PrimorskaSlovenian Society of Discrete and Applied MathematicsSociety of Mathematicians, Physicists and Astronomers of SloveniaInstitute of Mathematics, Physics and Mechanics, 2017-03-09)

A set D of vertices in a graph G is called a dissociation set if every vertex in D has at most one neighbor in D. We call a graph G uniformly dissociated if all maximal dissociation ...
Untangling nucleotide diversity and evolution of the H genome in polyploid Hordeum and Elymus species based on the single copy of nuclear gene DMC1

Sun, Dongfa; Sun, Genlou (Public Library of Science, 2012-12-10)

Numerous hybrid and polypoid species are found within the Triticeae. It has been suggested that the H subgenome of allopolyploid Elymus (wheatgrass) species originated from diploid Hordeum (barley) species, but the role ...
Unveiling the myth of the Muslim woman: a postcolonial critique

Mills, Albert J., 1945-; Golnaraghi, Golnaz (Emerald Group Publishing, 2013)

Purpose – The purpose of this paper is to examine the relationship between neo-colonialist discourse and Quebec's proposed Bill 94 aimed at restricting the public activities of niqab and veil-wearing Muslim women. ...

Using MOST to reveal the secrets of the mischievous Wolf–Rayet binary CV Ser

Guenther, David B.; David-Uraz, Alexandre; Moffat, Anthony F. J.; Chene, Andre-Nicolas; Rowe, Jason F.; Lange, Nicholas; Kuschnig, Rainer; Matthews, Jaymie M.; Rucinski, Slavek M.; Sasselov, Dimitar (Royal Astronomical Society, 2012)

The Wolf–Rayet (WR) binary CV Serpentis (= WR113, WC8d + O8-9IV) has been a source of mystery since it was shown that its atmospheric eclipses change with time over decades, in addition to its sporadic dust production. The ...
Using the 1.6 [micron]m bump to study rest-frame near-infrared-selected galaxies at redshift 2

Sorba, Robert; Sawicki, Marcin, 1969- (American Astronomical SocietyIOP Publishing, 2010-10-01)

We explore the feasibility and limitations of using the 1.6 [micron]m bump as a photometric redshift indicator and selection technique, and use it to study the rest-frame H-band galaxy luminosity and stellar mass functions ...
