G2P variant prediction techniques for ASR and STD
(Interspeech 2013, 2013)Introducing pronunciation variants into a lexicon is a balancing act: incorporating necessary variants can improve automatic speech recognition (ASR) and spoken term detection (STD) performance by capturing some of the ... -
Galactic cosmic rays in the outer heliosphere: theory and models
(Springer, 2011)We review recent advances in the field of galactic cosmic ray transport in the distant heliosphere. The advent of globalMHD models brought about a better understanding of the three-dimensional structure of the interface ... -
Galen and his treatise on grief
(AOSIS, 2016)Throughout his career, Fika Janse van Rensburg has rightly insisted on the importance of the socio-historical context in interpreting early Christian literature. Although New Testament scholars have given careful attention ... -
The Game Object Model and expansive learning: creation, instantiation, expansion, and re-representation
(Universiteit van die Vrystaat/ Sabinet, 2011)In this paper, the collaborative development, instantiation, expansion and re-representation as research instrument of the Game Object Model (GOM) are explored from a Cultural Historical Activity Theory perspective. The ... -
Game ranching inter-sectoral linkages: a structural path analysis for South Africa
(Taylor & Francis, 2014)Unfamiliarity with the economic structure of the game ranching sector is regarded as one of the reasons why questions are raised with regard to the potential economic impact of continued growth in the sector. This study ... -
Games for learning in accountancy education: a systematic literature review
(The Social Sciences Research Society, 2017)Background: Games for learning (educational games) are viewed as instructional strategies requiring students to engage in competitive activities with predetermined rules and conditions. Various studies propose beneficial ... -
Gamifying the industrial engineering profession
(IEOM, 2017)An age-old problem facing higher education institutes is the verification that the knowledge taught in class was actually learnt and internalized. Many consider that the quality of education is to be measured on this basis. ... -
Gaming is related to enhanced working memory performance and task-related cortical activity
(Elsevier, 2017)Gaming experience has been suggested to lead to performance enhancements in a wide variety of working memory tasks. Previous studies have, however, mostly focused on adult expert gamers and have not included measurements ... -
Gamma-gamma absorption in gamma-ray burst environments
(HEASA, 2016)Gamma-ray bursts (GRBs) are the most violent explosions in the universe, seen primarily as bright, short flashes of g-rays. Long GRBs are most likely associated with the violent death of a very massive star. They are ... -
Gamma-gamma absorption in the broad line region radiation fields of gamma-ray blazars
(IOP Publishing, 2016)The expected level of γγ absorption in the Broad Line Region (BLR) radiation field of γ-ray loud Flat Spectrum Radio Quasars (FSRQs) is evaluated as a function of the location of the γ-ray emission region. This is done ... -
Gamma-gamma absorption in the broad line region radiation fields of gamma-ray blazars. ERRATUM. (2016, ApJ, 821, 102)
(IOP Publishing, 2018)In the published article, our code to evaluate the γγ opacity due to the BLR radiation field contained a numerical error, due to which all opacities are a factor of 2π too low. The corrected Figures 2-4 are shown below. ... -
Gamma-gamma absorption in the γ-ray binary system PSR B1259-63/LS 2883
(IOP, 2017)The observed TeV light curve from the γ-ray binary PSR B1259-63/LS 2883 shows a decrease in the flux at periastron that has not been fully explained by emission mechanisms alone. This observed decrease can, however, be ... -
Gamma-ray and radio properties of six pulsars detected by the Fermi Large Area Telescope
(IOP, 2010)We report the detection of pulsed γ-rays for PSRs J0631+1036, J0659+1414, J0742-2822, J1420-6048, J1509-5850, and J1718-3825 using the Large Area Telescope on board the Fermi Gamma-ray Space Telescope (formerly known as ... -
Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
(EDP Sciences, 2017)Context. The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment’s sensitivityto lower energies. The lowest energy threshold is obtained using monoscopic analysis of data taken with ... -
Gamma-Ray emission from the shell of supernova remnant W44 revealed by the Fermi LAT
(AAAS, 2010)Recent observations of supernova remnants (SNRs) hint that they accelerate cosmic rays to energies close to ~1015 electron volts. However, the nature of the particles that produce the emission remains ambiguous. We report ... -
Gamma-ray observational properties of TeV-detected blazars
(IOP Science, 2013)The synergy between the Fermi-LAT and ground-based Cherenkov telescope arrays gives us the opportunity for the first time to characterize the high-energy emission from blazars over 5 decades in energy, from 100 MeV to 10 ... -
Gamma‐ray pulsar visibility
(AIP, 2005)PSR J0437‐4715 is a millisecond pulsar (MSP) thought to be “pair formation starved” (having limited pair cascades due to magnetic photon absorption). Fortunately the general relativistic (GR) electrodynamical model under ... -
Garcinia mangostana Linn displays antidepressant-like and pro-cognitive effects in a genetic animal model of depression: a bio-behavioral study in the Flinders Sensitive Line rat
(Springer, 2018)There is abundant evidence for both disorganized redox balance and cognitive deficits in major depressive disorder (MDD). Garcinia mangostana Linn (GM) has anti-oxidant activity. We studied the antidepressant-like and ... -
Garden ecosystem services of Sub-Saharan Africa and the role of health clinic gardens as social-ecological systems
(Elsevier, 2018)Rapid urbanization is predicted to take place in Africa in the near future and currently stressed cities will be even more overburdened in terms of pressure on green areas and increasing urban poverty. Effectively planning ... -
