Unlocking Climate Action: A Systematic Review of Pathways to Climate‐Friendly Cities Through Behavioral Change

Sustainable Development, EarlyView.
ABSTRACT Maintaining planetary borders is crucial to prevent significant Earth system shifts. Climate change, primarily driven by carbon emissions, necessitates reducing urban carbon footprints. Cities contribute significantly to emissions, and citizens play a crucial role in creating ecologically sustainable cities by changing attitudes.

Strong uniqueness of the Ricci flow [PDF]

Journal of Differential Geometry, 2009
In this paper, we derive some local a priori estimates for Ricci flow. This gives rise to some strong uniqueness theorems. As a corollary, let $g(t)$ be a smooth complete solution to the Ricci flow on $\mathbb{R}^{3}$, with the canonical Euclidean metric $E$ as initial data, then $g(t)$ is trivial, i.e. $g(t)\equiv E$.

The Basophil Activation Test Is the Most Accurate Test in Predicting Allergic Reactions to Baked and Fresh Cow's Milk During Oral Food Challenges

Allergy, EarlyView.
The BAT had larger areas under the receiver‐operator‐characteristic curve to identify BM (0.90) and FM (0.81) allergies compared to SPT (0.70 and 0.78) and sIgE (0.79 and 0.74) to cow's milk. Using optimal cut‐offs for BM allergy, sensitivity and specificity were 80/90% for BAT, 70/64% for SPT, and 90/66% for sIgE to cow's milk.

Designing, Developing and Examining the Effectiveness of a Machine Learning–Based Mobile Recommendation System for Parents' Digital Parenting Skills

Child &Family Social Work, EarlyView.
ABSTRACT It is of paramount importance that children are equipped with the requisite digital parenting skills to protect them from the risks and threats that they may encounter in the digital environment while also enabling them to seize the opportunities that the digital realm presents.

Geometric Classifications of Perfect Fluid Space-Time Admit Conformal Ricci-Bourguignon Solitons

Journal of Mathematics
This paper is dedicated to the study of the geometric composition of a perfect fluid space-time with a conformal Ricci-Bourguignon soliton, which is the extended version of the soliton to the Ricci-Bourguignon flow.

Eternal solutions to the Ricci flow [PDF]

Journal of Differential Geometry, 1993
A Ricci flow is a family of Riemannian metrics \(g = g(t)\) on a fixed manifold \(X\) such that \({\partial g\over \partial t} = -2 \text{Ric}\). (Let \text{Riem}, \text{Ric}, \(R\) denote the curvature tensor, Ricci tensor, scalar curvature respectively to \(g\).) It is assumed here to be eternal, i.e.

Assessing Walkability for Parents With Strollers: Challenges and Recommendations for Sustainable Urban Design

Children &Society, EarlyView.
ABSTRACT The significance of walkability in creating sustainable and livable cities cannot be overstated. However, the majority of cities in Turkey still struggle to meet the needs of vulnerable populations, particularly parents with children aged 0–6, in terms of walkability.

Charting cellular differentiation trajectories with Ricci flow

Nature Communications
Complex biological processes, such as cellular differentiation, require intricate rewiring of intra-cellular signalling networks. Previous characterisations revealed a raised network entropy underlies less differentiated and malignant cell states.

Ricci flow and the holonomy group [PDF]

Journal für die reine und angewandte Mathematik (Crelles Journal), 2012
Abstract. We prove that the reduced holonomy group of a complete smooth solution to the Ricci flow of uniformly bounded curvature cannot spontaneously contract within the lifetime of the solution. It follows then, from an earlier result of Hamilton, that the holonomy is exactly preserved by the equation. In particular, a solution to the
