Discordance of 3rd and 4th generation QuantiFERON-TB Gold assays by pregnancy stages in India

open access: yesJournal of Clinical Tuberculosis and Other Mycobacterial Diseases
Background: Pregnancy and HIV affect CD4+ T lymphocytes and impact performance of QuantiFERON-TB Gold (QFT). We compared the results of QFT with QuantiFERON-TB Gold Plus (QFT-Plus), which also measures CD8+ responses to TB antigens, during pregnancy and ...

Work Versus Force: Simultaneous Processes for Describing Interactions

open access: yesAdvanced Physics Research, Volume 5, Issue 6, June 2026.
ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

What is QFT? Resurgent trans-series, Lefschetz thimbles, and new exact saddles [PDF]

open access: yes, 2015
This is an introductory level review of recent applications of resurgent trans-series and Picard-Lefschetz theory to quantum mechanics and quantum field theory. Resurgence connects local perturbative data with global topological structure.

How important is iϵ in QFT? [PDF]

open access: yesInternational Journal of Modern Physics A, 2015
We discuss the role of iϵ in quantum field theories and suggest that it can be identified with the dimensional regularization parameter iϵ = 4-d thus clarifying and simplifying issues related to the infrared divergences without altering any of the present knowledge in QFT. We further present the relevance of this assumption for the optical theorem.

A Structure‐Based Benchmarking Suite for Quantum Learning

open access: yesConcurrency and Computation: Practice and Experience, Volume 38, Issue 10, May 2026.
ABSTRACT The application of quantum computing to Data Processing has naturally extended into the realm of quantum machine learning. However, while numerous benchmarks exist for evaluating quantum hardware, there remains a scarcity of tailored benchmarks that assess the intrinsic performance of learning models.
