Elevated Neopterin Levels Are Associated with Increased Tuberculosis Risk in Rheumatoid Arthritis Patients with QuantiFERON Conversion during Biologic Therapy. [PDF]

open access: yesPLoS ONE, 2016
QuantiFERON-TB-Gold (QFT-G) conversion is frequently observed in rheumatoid arthritis (RA) patients receiving biologic therapy. However, there have not been any known biomarkers available for detecting tuberculosis (TB) in QFT-G converters.

From the octagon to the SFT vertex — gluing and multiple wrapping

open access: yesJournal of High Energy Physics, 2017
We compare various ways of decomposing and decompactifying the string field theory vertex and analyze the relations between them. We formulate axioms for the octagon and show how it can be glued to reproduce the decompactified pp-wave SFT vertex which in

Extraordinary methane levels in a small bar‐built tropical estuary

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Small estuaries link uplands and nearshore marine environments but are understudied in many regions. We quantified spatial and temporal variability in CH4, CO2, nutrients, and organic matter in a small, deep, bar‐built tropical estuary in Fajardo, Puerto Rico.

Information Dynamics and Learning in Complex Adaptive Systems: Toward a Transdisciplinary Framework

open access: yesSystems Research and Behavioral Science, Volume 43, Issue 4, Page 1344-1363, July/August 2026.
ABSTRACT This article develops a framework for understanding learning and adaptation in complex adaptive systems. Drawing from neuroscience, systems theory, information theory and quantum field theory, it examines how information processing, plasticity and systemic coherence emerge from distributed, nonlinear and feedback‐driven interactions. It argues

Wiener-Hopf solution of the free energy TBA problem and instanton sectors in the O(3) sigma model

open access: yesJournal of High Energy Physics
Perturbation theory in asymptotically free quantum field theories is asymptotic. The factorially growing perturbative coefficients carry information about non-perturbative corrections, which can be related to renormalons and instantons.

Fluctuating Behavior and Influential Factors in the Performance of the QuantiFERON-TB Gold In-Tube Assay in the Diagnosis of Tuberculosis. [PDF]

open access: yesPLoS ONE, 2015
The QuantiFERON-TB Gold In-Tube (QFT-GIT) is a newly developed but widely used interferon-γ release assay for diagnosing tuberculosis (TB). However, research has not determined whether age or the use of an immune suppressive or anti-TB treatment ...

Guselkumab Safety in Patients With Latent Tuberculosis: Analysis of 11 Studies in Psoriatic Disease

open access: yesThe Journal of Dermatology, Volume 53, Issue 7, Page 1026-1031, July 2026.
ABSTRACT Certain psoriatic disease treatments, including tumor necrosis factor‐α inhibitors (TNFi), increase tuberculosis (TB) risk. Testing for latent TB infection (LTBI) before initiating systemic therapy has been standard practice for psoriasis (PsO) patients; however, updated consensus states routine testing is not required before initiating ...
