Interval QFT: a mathematical and computational enhancement of QFT
International Journal of Robust and Nonlinear Control, 2002 AbstractThe paper presents an overview of a mathematical and computational enhancement of Horowitz's QFT design procedure. The enhancement uses methods of interval analysis and is called as interval QFT, or IQFT. IQFT addresses and solves some of the fundamental issues in QFT, concerning selection of design frequencies, selection of controller phases ...

Comparison of QFT-Plus and QFT-GIT tests for diagnosis of M. tuberculosis infection in immunocompetent Korean subjects. [PDF]
Journal of Thoracic Disease, 2019 Background QFT-Plus is a recently developed next-generation QuantiFERON-TB Gold In-Tube (QFT-GIT) test. Unlike the QFT-GIT test, it includes a TB2 antigen tube with peptides that may stimulate CD8+ T cells. This study evaluated the diagnostic performance

Consistency of Higgsplosion in localizable QFT [PDF]
Physics Letters B, 2018 We show that large n-particle production rates derived in the semiclassical Higgsplosion limit of scalar field theoretical models with spontaneous symmetry breaking, are consistent with general principles of localizable quantum field theory.

Aspects of Berry phase in QFT [PDF]
Journal of High Energy Physics, 2017 When continuous parameters in a QFT are varied adiabatically, quantum states typically undergo mixing — a phenomenon characterized by the Berry phase. We initiate a systematic analysis of the Berry phase in QFT using standard quantum mechanics methods ...

Comparison of QFT-IT and QFT-Plus for Detecting Latent Tuberculosis in HIV-Infected Iranian Patients [PDF]
Novelty in BiomedicineBackground: Tuberculosis (TB) is a major public health issue, especially among Human immunodeficiency virus (HIV)-infected individuals, where early detection of latent tuberculosis infection (LTBI) is crucial.

Quantum Information in Relativity: The Challenge of QFT Measurements [PDF]
Entropy, 2021 Proposed quantum experiments in deep space will be able to explore quantum information issues in regimes where relativistic effects are important. In this essay, we argue that a proper extension of quantum information theory into the relativistic domain ...

BMC Infectious Diseases, 2023 Background QuantiFERON-TB Gold Plus (QFT-Plus) is an important test that has emerged in recent years for detecting TB infection. We conducted a review to compare the sensitivity, specificity and positive rate of QFT-Plus with that of QuantiFERON-TB Gold ...

The pragmatic QFT measurement problem and the need for a Heisenberg-like cut in QFT [PDF]
Synthese, 2022 Despite quantum theory’s remarkable success at predicting the statistical results of experiments, many philosophers worry that it nonetheless lacks some crucial connection between theory and experiment.

Entropic order parameters for the phases of QFT [PDF]
Journal of High Energy Physics, 2020 We propose entropic order parameters that capture the physics of generalized symmetries and phases in QFT’s. We do it through an analysis of simple properties (additivity and Haag duality) of the net of operator algebras attached to space-time regions ...
