Multivariate analysis of the immune response upon recent acquisition of Mycobacterium tuberculosis infection
… that were defined based on their longitudinal QFT results: the recent QFT converters, the QFT reverters, the persistent QFT positives and negatives. Analysis was based on the integration of different arms of the immune response, including adaptive and “innaptive” responses, measured on the …

The quantum Fourier transform and quantum chaos
… of this work is the quantum Fourier transform (QFT), an essential gate for quantum algorithms and quantum simulations. Experiments are performed on a three qubit liquid-state nuclear magnetic resonance quantum information processor, and demonstrate salient features of the QFT in both of these …

Algorithmic Quantum-State Generation for Simulating Quantum Field Theories on a Quantum Computer
Simulating a quantum field theory (QFT) on a quantum computer comprises three steps: generating an initial state, simulating time evolution and measuring observables, with the initial-state generation being the most expensive step for the entire simulation. In this thesis, we introduce a general …

The predictive value of a QuantiFERON conversion in the development of active tuberculosis disease in adolescents
… who were identified to have converted their QFT status during the original study will be followed up and observed for the occurrence of active TB disease over a period of two years. A similar sized, random sample of participants identified to have a QFT status that remained negative …

Numerical implementations of holographic duality via the fluid/gravity correspondence
… duality, in which a quantum field theory (QFT) is dual to a gravitational theory with the QFT defined on the boundary. Since we can regard hydrodynamics as a low-energy description of many QFTs, the fluid/gravity correspondence lets us probe holographic duality for QFTs at low energy. In …

Characterisation of T cell specificity, functional, activation and memory profiles associated with QuantiFERON TB Gold conversion and reversion
… assay [IGRA e.g. QuantiFERON TB GOLD (QFT)], is commonly thought to be a chronic state. However, longitudinal studies have demonstrated the dynamic nature of M.tb infection, whereby TSTs and IGRAs revert from a positive to a negative test in some individuals, possibly an indication of …

The incidence of tuberculosis in adolescents in the context of proposed TB vaccine trials
… assay, the QuantiFERON® TB Gold (in-tube) assay (QFT). They were also screened for TB disease using an algorithm composed of a set of screening tests. They were followed up for at least two years for incident TB and the predictive value of the baseline TST and QFT for incident TB disease was …

“The experiences I give them, that is going to be their opinion” : Formative assessment through dialogue in Technology Education
… Questioning Framework for Technology - Primary (QFT-P). This study, thus, contributes to the research in formative assessment and dialogue in TE in primary schools - two areas that have limited research to date. This research addresses the research gap in the process of IFA in TE, teacher beliefs …

A study to evaluate immunodiagnostic tests for tuberculosis infection and determinants of TB infection in a population of health care workers in the Western Cape of South Africa
… TST, QuantiFERON - TB Gold In - Tube (QFT - GIT) and a T - SPOT.TB test. All tests were repeated one year later. Results: The prevalence of TB infection at baseline was 84%, 65% and 60% as measured by TST, QFT - GIT and T - SPOT.TB. There was only fair agreement between TST and IGRAs. …

On the Generation of Entanglement in Ytterbium Clock Atoms and a Novel Interpretation of the Madelung Fluid Theory of Quantum Mechanics
… theory is applied to a toy quantum field theory (QFT) for the first time. This generates a classical set of equations, that contain QFT dynamics. It was not yet proven to be entirely equivalent to the starting QFT. Like how the NMT illustrated a hidden fifth fundamental force, the NMT version of …
