N-acetyl cysteine as therapeutic intervention in a “two-hit” model of maternal inflammation and post-natal methamphetamine exposure
(Elsevier, 2016)Schizophrenia is a severe neurodegenerative, pro- gressive degenerative illness, prevalent in 0.5−1% of the world population. It is causally associated with a genetic aspect as well as early-life environmental stress. ... -
N-gram based language identification of individual words
(PRASA, 2013)Various factors influence the accuracy with which the language of individual words can be classified using n-grams. We consider a South African text-based language identification (LID) task and experiment with two different ... -
Network resonance detection using harmonic active power
(IEEE, 2018)Resonances in electrical distribution systems can result in amplification of harmonics, which is undesirable in electrical networks. To avoid intrusive measurement techniques, in the majority of the cases network modeling ... -
Neural models for benchmarking of truck driver fuel economy performance
(INSTICC, 2019)The transport industry is a primary contributor towards emissions that impact climate change. Fuel economy is also of critical importance to the profitability of road freight transport operators. Empirical evidence identified ... -
New advances in pulsar magnetosphere modelling
(Sissa Medialab, 2016)The wealth of high-energy (E &50MeV) and very-high-energy (E >100 GeV) data accumulated over the past few years have provided unprecedented opportunities to probe pulsar emission models. The Fermi Large Area Telescope ... -
New method for determination of diffusion coefficients in turbulent plasmas
(Sissa Medialab, 2015)The transport of charged particles in turbulent magnetic fields is a topic of great interest in as- trophysics, since our ability to successfully use cosmic rays as astronomic messengers depends on our understanding of ... -
“No more going to Nandos”: Rudimentary statistics and venal public servants in tender adjudication
(SAAPAM, 2014)This paper advances the notion that corruption in public service is perpetrated by the corruptibility of functionaries. The psychopathology of corruption demonstrates that hominids are inherently venal and will thus ... -
Noise matching in coupled antennas
(IEEE, 2018)A novel way to calculate the sensitivity and beam- former coefficients of a receiver consisting of coupled antennas and an optimum beamformer is presented. The low-noise ampli- fier (LNA) connected ... -
A non-linear simulation model of an active magnetic bearings supported rotor system
(IEEE, 2010)Nowadays active magnetic bearings (AMBs) are utilized in a wide range of applications including high-speed flywheel energy storage devices. This paper aims at reporting on the modeling and simulation of a flywheel energy ... -
NT-proBNP and metabolic risk factors in two ethnic groups: the SABPA cohort study
(Oxford Univ Press, 2018)Background: Natriuretic peptides are vasoactive peptides with several metabolic actions. Purpose: We aimed to explore associations of N-terminal pro-brain natriuretic peptide (NT-proBNP) with metabolic traits in a mixed ... -
Number pronunciation in a multilingual environment and implications for an ASR system
(PRASA, 2014)The purpose of this paper is to address the challenges and describe step-by-step solutions faced when developing an automatic speech recognition system in multilingual societies. We give a brief statistical analysis of the ... -
Numerical simulation of break flows occurring in the reactor cavity cooling system of a very high temperature reactor using a system CFD approach
(ANS (American Nuclear Society), 2016)To avoid accidents due to human error or the failure of components, the reactor cavity cooling system (RCCS) of a high temperature reactor must be able to operate naturally or passively safe. The system under consideration ... -
Nutrition-related concerns of the primary caregiver regarding children with spastic cerebral palsy: a cross-sectional, quantitative research study
(Karger, 2017)Background and objectives: Parents with children suffering from spastic cerebral palsy (CP) face various challenges regarding their child’s health, nutritional status, growth, development and quality of ... -
Observation of the extremely bright flare of the FSRQ 3C279 with H.E.S.S. II
(PoS, 2017)In June 2015, the Flat Spectrum Radio Quasar 3C 279 underwent an extremely bright gamma-ray flare, with an increase of the flux above 100 MeV by a factor 10 in less than 1 day, revealing an intrinsic variability timescale ... -
Observations and modeling of gamma-ray millisecond pulsars seen with the Fermi LAT
(AIPC, 2011)We present a summary of gamma-ray millisecond pulsar (MSP) observations with the Fermi Large Area Telescope. The radio and gamma-ray light curves of these MSPs have been modeled in the framework of the retarded vacuum ... -
Observations of the blazar PKS 2023-07 in flaring state with H.E.S.S. And Fermi-LAT in 2016-2017 and constraints on an intrinsic cut-off
(Sissa Medialab, 2019)PKS 2023−07 is a flat spectrum radio quasar located at a redshift z = 1.388, farther than any source currently detected at very high energies (E > 100 GeV). At such energies, absorption by the extragalactic background ... -
Observations of the flaring Fermi-LAT blazars and prospects in spectro-polarimetry with SALT-RSS
(HEASA, 2016)The Fermi Gamma-Ray Space telescope has identified 1741 active galactic nuclei during its first four years of observation (2008-2012) and detected 1145 blazars and 573 blazar candidates of uncertain type (BCUs) as listed ... -
Off Line Partial Discharge as an essential Condition Based Monitoring (CBM) Tool for busbar insulation monitoring on Air Insulated Switchgear (AIS)
(NWU, 2018)This paper investigates the effectiveness of current test methods and procedures associated with insulation testing on the busbar of Air Insulated Switchgear (AIS) during scheduled planned maintenance. An improved test ...
