Efficient Data Assimilation Method for Optimizing Prediction of Flow Field and Sediment Transport in Open Channel

open access: yesRiver Research and Applications, Volume 42, Issue 3, Page 580-593, March 2026.
ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter k s in a shallow‐water equation model (via the momentum ...

Implementing Wound Hygiene in the Italian Healthcare Context: Expert Recommendations for the Management of Venous Leg Ulcers

open access: yesInternational Wound Journal, Volume 23, Issue 3, March 2026.
ABSTRACT The ‘Wound Hygiene Italia’ project was designed to provide expert‐driven recommendations for the assessment, management and monitoring of venous leg ulcers, tailored to diverse settings of care (hospital, ambulatory and home care). The recommendations, developed by a multidisciplinary panel, emphasise the implementation of the Wound Hygiene ...

Paradiplomacy and City Diplomacy From the Theoretical Perspectives of Tourism and International Relations: An Analysis of the City of São Paulo, Brazil

open access: yesLatin American Policy, Volume 17, Issue 1, March 2026.
ABSTRACT Tourism and International Relations, as interdisciplinary fields, encompass diverse knowledge, making them complex subjects. This article explores how official international relations bodies at subnational levels influence tourism using paradiplomacy and city diplomacy concepts.

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

open access: yesNuclear 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 ...

Eggs and Associated Nutrients: Implications for Brain Development and Function From Conception to Early Adulthood: A Narrative Review

open access: yesNutrition Bulletin, Volume 51, Issue 1, Page 46-66, March 2026.
ABSTRACT Brain development is an ongoing process that occurs throughout the first 1000 days of life (conception until 2 years) and proceeds throughout childhood, adolescence and up until early adulthood. Adequate nutrient intakes are crucial for both neurodevelopment inside the womb and critical life‐stages thereafter when the brain continues to grow ...

University Collaboration and Digitalization in SMEs: The Mediating Role of Managers' Digital Knowledge

open access: yesR&D Management, Volume 56, Issue 2, Page 338-362, March 2026.
ABSTRACT Digital technologies change the nature of product and service development and challenge established firms to adapt to the new digital environment. As small and medium‐sized enterprises (SMEs), in particular, lack the resources necessary to digitally transform their business, they are forced to find new strategies to stay competitive in a ...

Toral symmetries of collapsed ancient solutions to the homogeneous Ricci flow

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract Collapsed ancient solutions to the homogeneous Ricci flow on compact manifolds occur only on the total space of principal torus bundles. Under an algebraic assumption that guarantees flowing through diagonal metrics and a tameness assumption on the collapsing directions, we prove that such solutions have additional symmetries, that is, they ...

The Ricci flow for nilmanifolds

open access: yesJournal 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.

Ageing attenuates regional vasoconstriction during acute lowering of upper and lower limbs

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 674-683, 1 March 2026.
Abstract The venoarteriolar and myogenic response (VMR) is a non‐adrenergic, non‐baroreflex‐mediated mechanism that increases local vascular resistance and contributes to blood pressure (BP) regulation during orthostasis. Despite the importance of the VMR in human cardiovascular control, no information exists elucidating possible differences in the VMR
