Nonlinear multidimensional cosmological models with form fields: stabilization of extra dimensions and the cosmological constant problem

open access: yes, 2003
We consider multidimensional gravitational models with a nonlinear scalar curvature term and form fields in the action functional. In our scenario it is assumed that the higher dimensional spacetime undergoes a spontaneous compactification to a warped ...

The King's Evil Without the King: The Royal Touch during the Interregnum

open access: yesJournal of Religious History, Volume 49, Issue 4, Page 439-454, December 2025.
This article examines how far, and in what ways, the traditional belief that English monarchs could cure scrofula (the “King's Evil”) by royal touch survived during the eleven years of the Interregnum (1649–1660). Charles I had been executed and the monarchy abolished, and Charles II was in exile for the vast majority of this period. It might seem that

Linking Phase Transitions and Quantum Entanglement at Arbitrary Temperature

open access: yes, 2018
In this work, we establish a general theory of phase transitions and quantum entanglement in the equilibrium state at arbitrary temperatures. First, we derived a set of universal functional relations between the matrix elements of two-body reduced ...

Aflatoxin Contamination in Agri‐Food Systems: A Comprehensive Review of Toxicity, Food Security, Economic Impacts, and Sustainable Mitigation Across the Value Chain

open access: yesFood Science &Nutrition, Volume 13, Issue 10, October 2025.
Toxic and carcinogenic aflatoxins from Aspergillus contaminate global staple crops, threatening food security, public health, and causing $6–18B in annual economic losses. Climate change, poor agricultural and post‐harvest practices, and socioeconomic constraints intensify aflatoxin contamination risks. Sustainable mitigation strategies from biocontrol

Short‐Term Exposure to Fine Particulate Matter (PM2.5), Cause Specific‐Mortality, and High‐Risk Populations: A Nationwide Time‐Stratified Case‐Crossover Study

open access: yesGeoHealth, Volume 9, Issue 10, October 2025.
Abstract Numerous studies have reported that short‐term exposure to fine particulate matter (PM2.5) is associated with mortality risk; however, results on high‐risk populations and regions have been mixed. This study performed a nationwide time‐stratified case‐crossover study to assess the association between short‐term PM2.5 and mortality in South ...

Quantum groups, Yang-Baxter maps and quasi-determinants

open access: yes, 2017
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang-Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...
