Evaluation of QuantiFERON TB gold plus among TB household contacts in high incidence settings

BMC Infectious Diseases
Background Accurately identifying and categorizing individuals who are latently infected is critical for developing prevention strategies against tuberculosis (TB) disease.

Replica Wormholes and Quantum Hair

Fortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The recent applications of Euclidean path integrals to the black hole information problem are discussed. In calculations with replica wormholes as the next‐to‐leading order correction to the Gibbons–Hawking saddlepoint, the radiation density matrix approaches a pure state at late times, following the Page curve.

Role of interferon gamma release assay in the diagnosis and management of Mycobacterium tuberculosis-associated uveitis: a review

BMJ Open Ophthalmology, 2021
Tuberculosis (TB)-associated uveitis is a common cause of infectious uveitis in the developing world. Diagnosis of TB uveitis remains a challenge. The role of interferon gamma release assays (IGRAs) is uncertain.

IFN‐γ Levels and Indeterminate Rate: Comparative Analysis of Three Commercial Interferon‐Gamma Release Assays for Diagnosis of Mycobacterium tuberculosis Infection

Advances in Public Health, Volume 2026, Issue 1, 2026.
Background The diagnosis of Mycobacterium tuberculosis infection increasingly relies on interferon‐gamma release assay (IGRA) technologies. Despite their usefulness, inconsistency in IFN‐γ responses and the persistence of indeterminate results remain problematic across IGRA platforms.

Performance of QuantiFERON-TB Gold Plus for detection of latent tuberculosis infection in pregnant women living in a tuberculosis- and HIV-endemic setting.

PLoS ONE, 2018
We evaluated the performance of QuantiFERON-TB Gold Plus (QFT-Plus), which includes two Mycobacterium tuberculosis antigen formulations (TB1 and TB2), for detection of latent tuberculosis infection during pregnancy.

First insight into latent tuberculosis infection among household contacts of tuberculosis patients in Duhok, Iraqi Kurdistan: using tuberculin skin test and QuantiFERON-TB Gold Plus test

International Journal of Infectious Diseases, 2020
Background: The objectives were to estimate the prevalence of latent tuberculosis infection (LTBI) among household contacts (HHCs) with active TB patients, and to identify their risk factors.

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

Annalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

Predicting Flow in Fracture Networks With Quantum Algorithms

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Uncertainty quantification plays a crucial role in the modeling of subsurface flow. For instance, uncertainties in the properties of geologic fracture networks significantly impact flow, requiring numerous simulations to accurately estimate quantities of interest.

W‐algebras, Gaussian free fields, and g$\mathfrak {g}$‐Dotsenko–Fateev integrals

Proceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.
Abstract Based on the intrinsic connection between Gaussian free fields and the Heisenberg vertex algebra, we study some aspects of the correspondence between probability theory and W$W$‐algebras. This is first achieved by providing a construction of the W$W$‐algebra associated to a complex simple Lie algebra g$\mathfrak {g}$ by means of Gaussian free ...

Quantum‐Inspired Fourier Transforms Based on Circuits

Advanced Science, Volume 12, Issue 42, November 13, 2025.
An analog scheme of classical circuit for the quantum Fourier transform is proposed. The number of the basic computing components employed in the circuit design is consistent with the number of the quantum gate in the quantum circuit. The information is encoded using correlated electrical signals.
