Curvature estimates for the Ricci flow I [PDF]

Calculus of Variations and Partial Differential Equations, 2007
In this paper we present several curvature estimates and convergence results for solutions of the Ricci flow. The curvature estimates depend on smallness of certain local space-time integrals of the norm of the Riemann curvature tensor, while the convergence results require finiteness of space-time integrals of the norm of the Riemann curvature tensor.

“I think people's perception that her reading is good enough. That would be a worry to me.” Mother and child perspectives of school‐related reading for children with Down syndrome

Journal of Research in Special Educational Needs, Volume 26, Issue 4, October 2026.
Abstract There is growing interest in children's reading experiences, both volitional and those initiated by, or connected to, school‐related reading. However, the majority of this research focuses on the reading experiences of neurotypical children; limiting understanding and the potential to improve support for other groups of children.

Singularities of Connection Ricci Flow and Ricci Harmonic Flow

, 2013
In this paper, we study the singularities of two extended Ricci flow systems --- connection Ricci flow and Ricci harmonic flow using newly-defined curvature quantities. Specifically, we give the definition of three types of singularities and their corresponding singularity models, and then prove the convergence. In addition, for Ricci harmonic flow, we

Non-local interaction in discrete Ricci curvature-induced biological aggregation

Royal Society Open Science
We investigate the collective dynamics of multi-agent systems in two- and three-dimensional environments generated by minimizing discrete Ricci curvature with local and non-local interaction neighbourhoods.

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Early neurodevelopmental outcome in newborns with mild hypoxic‐ischaemic encephalopathy

Developmental Medicine &Child Neurology, Volume 68, Issue 9, Page 1261-1268, September 2026.
Abstract Aim To describe the natural history of newborn children with mild hypoxic‐ischaemic encephalopathy in the first year of life. Method This was a multicentre, prospective observational study involving five neonatal intensive care units in an Italian region using both structured clinical and neurophysiological assessments according to the Italian

SmartTur+ECO: A Multimodal Conversational Recommender System Integrating Virtual Reality and Gamification for Smart Tourism

Expert Systems, Volume 43, Issue 9, September 2026.
ABSTRACT This paper presents SmartTur+ECO, a system for tourist attractions that integrates conversational recommendation systems (CRS), virtual reality (VR) and gamification. It efficiently gathers trip data and elicits user preferences through interactions with a chatbot, addressing the user‐cold start problem common in tourism.
