INTRODUCTION Healthcare workers (HCWs) are exposed to Mycobacterium tuberculosis (MTB) and therefore are screened for tuberculosis (TB). Results of TB screenings with the Interferon-γ Release Assay (IGRA) in a French psychiatric hospital without a TB ward are described. METHODS At the Sainte-Anne Hospital, a referral centre for psychiatric patients throughout the municipal region of Paris, IG...

The aim of this study was to evaluate the sensitivity and specificity of a whole blood interferon-γ release assay, the QuantiFERON®-TB Gold In-Tube (QFT-GIT) test, in the diagnosis of Mycobacterium tuberculosis (MTB) infection, and to assess its monitoring role during antitubercular treatment. In total, 20 patients received the QFT test, along with other commonly-used tests, prior to, and follo...

OBJECTIVE To assess the performance of the QuantiFERON-TB Gold in-tube (QFT-GIT) assay for tuberculosis (TB) screening using a convenience sample from among a population of healthcare provider (HCP) employees of a hospital. METHODS For the individuals in our cohort, we reviewed occupational health records, including TB risk factors, and the results of QFT-GIT testing. We considered a QFT-GIT ...

A quantum Fourier transform (QFT) has been implemented on a three qubit nuclear magnetic resonance (NMR) quantum computer to extract the periodicity of an input state. Implementation of a QFT provides a first step towards the realization of Shor's factoring and other quantum algorithms. The experimental implementation of the QFT on a periodic state is presented along with a quantitative measure...

In this study, the security of Novel Enhanced Quantum Representation (NEQR) of quantum images are suggested by using the Quantum Fourier Transform (QFT ) with blind trent. In the protocol, QFT and keys are used to share signature with recipients. So all members know only their signature information which are encrypted output of the QFT . This improves the security of the protocol. In addition, ...

Parametric uncertainty is the one of the challenging task in many dynamical systems. In this paper QFT based PID Controller is developed to improve the performance for a pitch control of uncertain aircraft system. The controller is designed based on the dynamic modeling of system begins with a derivation of suitable mathematical model to describe the longitudinal motion of an aircraft. Genetic ...

In this study, quantum proxy group signature protocol based on the Quantum Fourier Transformation (QFT ) is suggested. In this protocol, QFT is used to share signature with group members. So all proxy group members know only their part of the signature information which are encrypted output of the QFT . This improves the security of the protocol. In addition, the security of the quantum proxy g...

The renormalization group (RG) has been characterized as merely a coarse-graining procedure that does not illuminate the microscopic content of quantum field theory (QFT), but merely gets us from that content, as given by axiomatic QFT, to macroscopic predictions. I argue that in the constructive field theory tradition, RG techniques do illuminate the microscopic dynamics of a QFT, which are no...

A number of elegant approaches have been developed for the identification of quantum circuits which can be efficiently simulated on a classical computer. Recently, these methods have been employed to demonstrate the classical simulability of the quantum Fourier transform (QFT). Here we show that one can demonstrate a number of simulability results for QFT circuits in a straightforward manner us...
