Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Modulation of interferon-gamma response to QuantiFERON-TB-plus detected by enzyme-linked immunosorbent assay in patients with active and latent tuberculosis infection

International Journal of Mycobacteriology, 2016
Objective/Background: Interferon (IFN)-γ-release assays (IGRAs) are designed for the diagnosis of tuberculosis (TB) infection. The new IGRA called QuantiFERON-TB Plus (QFT-Plus) is based on enzyme-linked immunosorbent assay (ELISA) detection of IFN-γ ...

Monopoles, Clarified

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Intermediate‐Temperature Specific Heat of Solids and the Rationale Behind the Maier–Kelley Empirical Formula

physica status solidi (b), Volume 263, Issue 2, February 2026.
We develop a basic‐principles model from an analytically tractable semi‐harmonic Hamiltonian and compare our predictions with experimental data for Cu, Al, Pb, Si, and Ge. The results are quite satisfactory, considering that there are no fitting parameters in our theory.

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.

Research priorities for advanced HIV disease in Latin America and the Caribbean region: a modified Delphi study

Journal of the International AIDS Society, Volume 29, Issue 1, January 2026.
Abstract Introduction Advanced HIV disease (AHD) remains a leading cause of mortality in Latin America and the Caribbean (LAC), driven by late diagnosis, treatment gaps and structural barriers, particularly among key populations and children. Persistent disparities in healthcare access, stigma, and limited health system capacity highlight the need for ...

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.

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.

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.
