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

open access: yesphysica 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.

Coupling a QFT to a TQFT and duality [PDF]

open access: yes, 2014
A bstractWe consider coupling an ordinary quantum field theory with an infinite number of degrees of freedom to a topological field theory. On $ \mathbb{R} $d the new theory differs from the original one by the spectrum of operators.

Localised Kikuchi–Fujimoto Disease With Mediastinal Lymphadenopathy: A Case Initially Mimicking Malignant Lymphoma on Endobronchial Ultrasound‐Guided Transbronchial Needle Aspiration Cytology

open access: yesRespirology Case Reports, Volume 14, Issue 2, February 2026.
We report a rare case of isolated mediastinal Kikuchi–Fujimoto disease (KFD) in a 37‐year‐old woman, which was initially misinterpreted as malignant lymphoma based on EBUS‐TBNA cytology. Definitive diagnosis was achieved through video‐assisted thoracoscopic surgery, revealing characteristic massive necrosis and histiocytic infiltration.

Reducing CNOT count in quantum Fourier transform for the linear nearest-neighbor architecture

open access: yesScientific Reports, 2023
Physical limitations of quantum hardware often necessitate nearest-neighbor (NN) architecture. When synthesizing quantum circuits using the basic gate library, which consists of CNOT and single-qubit gates, CNOT gates are required to convert a quantum ...

Non relativistic limit of integrable QFT and Lieb–Liniger models [PDF]

open access: yes, 2016
In this paper we study a suitable limit of integrable QFT with the aim to identify continuous non-relativistic integrable models with local interactions.

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

open access: yesJournal 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 ...

QFT-Plus: a plus in variability? – Evaluation of new generation IGRA in serial testing of students with a migration background in Germany

open access: yesJournal of occupational medicine and toxicology, 2017
BackgroundCurrently available Interferon-gamma release assays (IGRAs) show a considerable variability in serial testing for latent tuberculosis infection (LTBI).This study offers first results for the new generation IGRA QuantiFERON-TB Gold Plus (QFT ...

Replica Wormholes and Quantum Hair

open access: yesFortschritte 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.

Second order transport coefficients of nonconformal relativistic fluids in various dimensions from Dp-brane

open access: yesJournal of High Energy Physics, 2019
We derive all the dynamical second order transport coefficients for Dp-brane with p from 1 to 6 within the framework of fluid/gravity correspondence in this paper.
