G-quadruplex formation of FXYD1 pre-mRNA indicates the possiblity of regulating expression of its protein product
(2014-10-15)G-quadruplexes are higher-order nucleic acid structures formed of square-planar arrangements of four guanine bases held together by Hoogsteen-type hydrogen bonds. Stacks of guanine tetrads are stabilised by intercalating ... -
A G.984 GPON Exhibiting Multi-Wavelength Protocol Functionalities
(2010)A Gigabit Passive Optical Network (GPON) upstream-map frame- format enhancement has been developed to accommodate dynamic multi wavelength (DMW) transmission over splitter-based GPONs. Accordingly network functionality has ... -

The G305 Star Forming Complex: a Panoramic View of the Environment and Star Formation
(2012-11-20)This thesis presents molecular line and radio continuum observations of the giant molecular cloud (GMC) complex known as G305. The energy input from high-mass stars in the form of powerful winds and ionising radiation ... -
The G305 star-forming complex : a wide-area radio survey of ultracompact H ii regions
(2012-04)We present wide-area radio continuum 5.5 and 8.8 GHz (5.5 and 3.4 cm) Australia Telescope Compact Array observations of the complex and rich massive star-forming region G305. The aim of this study is to perform an un-targeted ... -
The G305 star-forming complex : radio continuum and molecular line observations
(2013-11-01)We present 109–115 GHz (3 mm) wide-field spectral line observations of 12CO, 13CO and C18O J = 1–0 molecular emission and 5.5 and 8.8 GHz (6 and 3 cm) radio continuum emission towards the high-mass star-forming complex ... -
The G305 star-forming complex : the central star clusters Danks 1 and Danks 2
(2012)The G305 H ii complex (G305.4+0.1) is one of the most massive star-forming structures yet identified within the Galaxy. It is host to many massive stars at all stages of formation and evolution, from embedded molecular ... -
The G305 star-forming complex : wide-area molecular mapping of NH3 and H2O masers
(2010)We present wide-area radio (12 mm) Mopra telescope observations of the complex and rich massive star-forming region G305. Our goals are to determine the reservoir for star formation within G305 using NH3 to trace the dense ... -
Ga(III) complexes-The effect of metal coordination on potential systemic absorption after topical exposure
(2011-05-10)The handling of elemental gallium is not thought to be harmful, but this assumption does not consider metal coordination which readily occurs in physiological fluids. The aim of this work was to determine Ga(III) coordination ... -
GA-NIFS: A massive black hole in a low-metallicity AGN at z ∼ 5.55 revealed by JWST/NIRSpec IFS
(2023-09-18)We present rest-frame optical data of the compact z=5.55 galaxy GS_3073 obtained using the integral field spectroscopy mode of the Near-InfraRed Spectrograph on board the James Webb Space Telescope. The galaxybs prominent ... -
GA-NIFS: Black hole and host galaxy properties of two z-6.8 quasars from the NIRSpec IFU
(2023-10-20)Aims. Integral field spectroscopy (IFS) with JWST NIRSpec will significantly improve our understanding of the first quasars, by providing spatially resolved, infrared spectroscopic capabilities that cover key rest-frame ... -
Gaeumannomyces graminis, the take-all fungus and its relatives
(2004-07)Take-all, caused by the fungus Gaeumannomyces graminis var. tritici, is the most important root disease of wheat worldwide. Many years of intensive research, reflected by the large volume of literature on take-all, has led ... -
The Gaia -ESO Survey : Empirical determination of the precision of stellar radial velocities and projected rotation velocities
(2015-08)Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims. A key aim is to provide precise radial velocities (RVs) and projected equatorial ... -
