Mean-field diffusive dynamics on weighted networks [PDF]

, 2010
Diffusion is a key element of a large set of phenomena occurring on natural and social systems modeled in terms of complex weighted networks. Here, we introduce a general formalism that allows to easily write down mean-field equations for any diffusive ...

The Binding of 3‐O‐Methylfluorescein Phosphate to the Catalytic Domain of the Human CDC25B Phosphatase: A Structural Investigation

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
Structural studies on the complex that CDC25B C473S (CDC25B‐S) forms with the 3‐O‐methylfluorescein phosphate (3‐OMFP) reveal how the fluorogenic substrate binds CDC25B‐S, engaging key binding regions and inducing structural adjustments that stabilize the protein.

Dynamically broken Anti-de Sitter action for gravity

, 2008
Due to a suitable Higgs mechanism, a standard Anti-de Sitter gauge theory becomes spontaneously broken. The resulting Lorentz invariant gravitational action includes the Hilbert-Einstein term of ordinary Einstein-Cartan gravity with cosmological constant,

From Barns to Bushes: Exploring the ECOFF‐Based Non‐Wild‐Type Status of Campylobacter spp. in Pets, Livestock, Synanthropic Birds and Wild Animals in Northwestern Italy

Zoonoses and Public Health, Volume 73, Issue 1, Page 30-44, February 2026.
ABSTRACT Introduction Antimicrobial resistance (AMR) poses a significant threat to both humans and animals. Zoonotic bacteria, such as Campylobacter, contribute to human infections and the spread of AMR, particularly through livestock, pets and wildlife. We investigated the prevalence, distribution and EUCAST ECOFF‐based wild‐type (WT) vs.
