Integrated Genomic and Epidemiological Surveillance to Monitor SARS‐CoV‐2 Variants in Italy: Insights From the JN.1 Case Study (2023–2024)

Journal of Medical Virology, Volume 98, Issue 1, January 2026.
ABSTRACT The epidemiology of SARS‐CoV‐2 is marked by the continuous emergence of new lineages. Early detection and assessment of their transmissibility can be challenging for surveillance systems that rely solely on case time series data. Genomic surveillance, focusing on identifying and characterizing circulating variants, can provide early insights ...

Embracing new practices in plant breeding for agroecological transition: A diversity‐driven research agenda

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 38-48, January 2026.
Plant breeding for agroecological transition (AET) holds the potential to transform agriculture by fostering crop diversification and empowering farmers through collaborative, inter‐ and transdisciplinary research. By adopting a systemic, co‐learning approach, we can deepen our understanding of the complex interactions between plant diversity ...

Grey‐Body Factors and Absorption Cross‐Sections of Scalar and Dirac Fields in the Vicinity of Dilaton‐De Sitter Black Hole

Fortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Introduction of the G2-Ricci flow: Geometric implications for spontaneous symmetry breaking and gauge boson masses

Nuclear Physics B
This work introduces the G2-Ricci flow on seven-dimensional manifolds with non-zero torsion and explores its physical implications. By extending the Ricci flow to manifolds with G2 structures, we study the evolution of solitonic solutions and their role ...

Trends on Strategies for Mitigation of Antibiotic Residues in Milk and Dairy Products Based on Scientometric Analysis and Systematic Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT The presence of antibiotic residues (ARs) in milk poses a significant challenge to public health and the dairy industry. This study presents the research trends on strategies to mitigate ARs in milk and dairy products, combining scientometric and systematic review approaches.

The Ricci flow for nilmanifolds

Journal of Modern Dynamics, 2010
We consider the Ricci flow for simply connected nilmanifolds, which translates to a Ricci flow on the space of nilpotent metric Lie algebras. We consider the evolution of the inner product and the evolution of structure constants, as well as the evolution of these quantities modulo rescaling.
