Full-sky bispectrum in redshift space for 21cm intensity maps
(IOP Publishing, 2020)We compute the tree-level bispectrum of 21cm intensity mapping after reionisation. We work in directly observable angular and redshift space, focusing on equal-redshift correlations and thin redshift bins, for which the ... -
A fumonisins immunosensor based on polyanilino-carbon nanotubes doped with palladium telluride quantum dots
(MDPI, 2015)An impedimetric immunosensor for fumonisins was developed based on poly(2,5-dimethoxyaniline)-multi-wall carbon nanotubes doped with palladium telluride quantum dots onto a glassy carbon surface. The composite was assembled ... -
Functional and structural analysis of predicted proteins obtained from homo sapiens' minisatellite 33.15-tagged transcript pAKT-45 variants
(Hindawi, 2020)The spermatozoa are transcriptionally dormant entities which have been recognized to be an archive of mRNA, coding for a variety of functionally crucial cellular proteins. This significant repository of mRNA is predicted ... -
Functional landscape of SARS-CoV-2 cellular restriction
(Cell Press, 2021)A deficient interferon (IFN) response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been implicated as a determinant of severe coronavirus disease 2019 (COVID-19). To identify the molecular ... -
Functional metal oxides synthesized using natural extracts from waste maize materials
(Elsevier, 2021)We show in this article the possibilities of employing an environmentally friendly, uncomplicated, economical and sustainable green synthesis technique effected by natural extracts from waste maize (zea mays lea) materials to ... -
Functional prediction of candidate micrornas for CRC management using in silico approach
(MDPI, 2019)Approximately 30–50% of malignant growths can be prevented by avoiding risk factors and implementing evidence-based strategies. Colorectal cancer (CRC) accounted for the second most common cancer and the third most common ... -
Fundamental physics with the square kilometre array
(Cambridge University Press, 2020)The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity and survey speed than any current radio ... -
Fungal‑derived compounds and mycogenic nanoparticles with antimycobacterial activity: a review
(Springer, 2022)Tuberculosis (TB) is a persistent lung infection caused by Mycobacterium tuberculosis. The disease is characterized by high mortality rates of over 1 million per year. Unfortunately, the potency and efectiveness of currently ... -
Further evidence for periodontal disease as a risk indicator for adverse pregnancy outcomes
(Elsevier, 2017)Although there is increasing evidence to suggest an association between periodontal disease and adverse pregnancy outcomes, the issue remains controversial. Study objective: This study tested the hypothesis that ... -
Further observations of Hipparcos red stars and standards for UBV(RI)C photometry
(Oxford University Press, 2007)We present homogeneous and standardized UBV(RI)C JHK photometry for over 100 M stars selected from an earlier paper on the basis of apparent photometric constancy. L photometry has been obtained for stars brighter than ... -
Fusion-assisted hydrothermal synthesis and post-synthesis modification of mesoporous hydroxy sodalite zeolite prepared from waste coal fly ash for biodiesel production
(MDPI, 2022)Increases in biodiesel prices remains a challenge, mainly due to the high cost of conventional oil feedstocks used during biodiesel production and the challenges associated with using homogeneous catalysts in the process. ... -
Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects
(EDP Sciences, 2017)CONTEXT: The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are ... -
The Galactic halo pulsar population
(Oxford University Press, 2018)Most population studies of pulsars have hitherto focused on the disc of the Galaxy, the Galactic centre, globular clusters, and nearby galaxies. It is expected that pulsars, by virtue of their natal kicks, are also to ... -
Galaxy and Mass Assembly (GAMA): A WISE Study of the Activity of Emission-line Systems in G23
(2020)We present a detailed study of emission-line systems in the GAMA G23 region, making use of WISE photometry that includes carefully measured resolved sources. After applying several cuts to the initial catalogue of ∼41,000 ... -
Galaxy And Mass Assembly (GAMA): Defining passive galaxy samples and searching for the UV upturn
(Oxford University Press, 2019)We use data from the GAMA and GALEX surveys to demonstrate that the UV upturn, an unexpected excess of ultraviolet flux from a hot stellar component, seen in the spectra of many early-type galaxies, arises from processes ... -
Galaxy and Mass Assembly (GAMA): Demonstrating the power of WISE in the study of Galaxy Groups to z < 0.1
(IOP Publishing, 2020)Combining high-fidelity group characterisation from the Galaxy and Mass Assembly (GAMA) survey and source-tailored z < 0.1 photometry from the WISE survey, we present a comprehensive study of the properties of ungrouped ... -
Galaxy and Mass Assembly (GAMA): Mid-infrared properties as tracers of galaxy environment
(EDP Sciences, 2023)We investigate how different mid-infrared (mid-IR) properties of galaxies are correlated with the environment in which the galaxies are located. For this purpose, we first study the dependence of galaxy clustering on the ... -
Galaxy And Mass Assembly (GAMA): Resolving the role of environment in galaxy evolution
(Oxford University Press, 2013)We present observations of 18 galaxies from the Galaxy And Mass Assembly (GAMA) survey made with the SPIRAL optical integral field unit (IFU) on the Anglo- Australian Telescope. The galaxies are selected to ... -

Galaxy and mass assembly: evolution of the Hα luminosity function and star formation rate density up to z < 0.35
(OUP, 2013)Measurements of the low-z Hα luminosity function, Φ, have a large dispersion in the local number density of sources (∼0.5–1 Mpc−3 dex−1), and correspondingly in the star formation rate density (SFRD). The possible causes ...
