Recoverability and Irreversible Information Loss in Physical Inference: Lessons From Quantum Measurement and Climate Reanalysis

Annalen der Physik, Volume 538, Issue 4, April 2026.
ABSTRACT Quantum Mechanics (QM) and Climate Science (CS) confront the epistemic problem of inferring an unobservable state from incomplete, indirect, and context‐dependent measurements. Although their physics differ profoundly (non‐commutative algebra vs.

Immunologic Profiling Suggests an Association Between Treg Cell Dysfunction and Pain in Knee Osteoarthritis

Arthritis &Rheumatology, Volume 78, Issue 4, Page 848-860, April 2026.
Objective Pain is the hallmark symptom of osteoarthritis (OA), and its biologic drivers remain poorly understood. Although the role of innate immunity in OA has been extensively studied, the involvement of adaptive immunity, in particular Treg cells, is not well understood.

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, Volume 2026, Issue 4, April 2026.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Excited state Rényi entropy and subsystem distance in two-dimensional non-compact bosonic theory. Part I. Single-particle states

Journal of High Energy Physics, 2020
We investigate the Rényi entropy of the excited states produced by the current and its derivatives in the two-dimensional free massless non-compact bosonic theory, which is a two-dimensional conformal field theory.

Kaniadakis Holographic Dark Energy Behavior in f(Q) Theory

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT In this study, the cosmological behavior of the Kaniadakis holographic dark energy model is investigated under the f(Q)$f(Q)$ theory within the framework of a flat Friedmann–Robertson–Walker (FRW) universe. The generalized holographic energy density based on Kaniadakis entropy is modeled using the Hubble horizon infrared cutoff scale, and the ...

Pseudo entropy and pseudo-Hermiticity in quantum field theories

Journal of High Energy Physics
In this paper, we explore the concept of pseudo Rényi entropy within the context of quantum field theories (QFTs). The transition matrix is constructed by applying operators situated in different regions to the vacuum state.

From modified Tsallis–Rényi entropy to a MOND-like force law, Bekenstein bound, and Landauer principle for black holes

Physics Letters B
We examine black hole thermodynamics within the framework of modified Rényi entropy and explore its implications in Modified Newtonian Dynamics (MOND), an extension of Newton's second law proposed to explain galaxy rotation curves without invoking dark ...

e3SIM: Epidemiological‐ecological‐evolutionary simulation framework for genomic epidemiology

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1051-1059, April 2026.
Abstract Infectious disease dynamics result from the complex interplay of epidemiological, ecological and evolutionary (epi‐eco‐evo) processes. Accurately modelling these coupled processes is crucial for understanding pathogen spread and informing public health strategies.

Renyi divergences from Euclidean quenches

, 2019
We study the generalisation of relative entropy, the Renyi divergence $D_{\alpha} ( \rho||\rho_\beta) $ in 2$d$ CFTs between an excited state density matrix $\rho$, created by deforming the Hamiltonian, and the thermal density matrix $\rho_\beta$.
