A design tool for globally developable discrete architectural surfaces using Ricci flow
Japan Architectural Review, 2023 This paper presents an approach for the design of discrete architectural surfaces that are globally developable; that is, having zero Gaussian curvature at every interior node.

Purely Coclosed G2‐Structures on Nilmanifolds—II
Mathematische Nachrichten, EarlyView.ABSTRACT This paper completes the classification of seven‐dimensional nilpotent Lie groups endowed with a left‐invariant purely coclosed G2$\text{G}_2$‐structure, initiated in Bazzoni et al. [Mathematische Nachrichten 296 no. 6 (2023): 2236–2257], the authors provided the classification of decomposable seven‐dimensional nilpotent Lie groups and of the ...

POSITIVITY OF RICCI CURVATURE UNDER THE KÄHLER–RICCI FLOW [PDF]
Communications in Contemporary Mathematics, 2006 In each complex dimension n ≥ 2, we construct complete Kähler manifolds of bounded curvature and non-negative Ricci curvature whose Kähler–Ricci evolutions immediately acquire Ricci curvature of mixed sign.

Precision agriculture for water saving: The case of processing tomato and table grape
PLANTS, PEOPLE, PLANET, EarlyView.Agriculture faces increasing pressure to produce high‐quality food while reducing water use under intensifying climate change and water scarcity. This study compared sensor‐based precision irrigation, drone monitoring, and near‐infrared spectroscopy with conventional farmer management in table grape and processing tomato production systems.

On the blow-up of four-dimensional Ricci flow singularities [PDF]
, 2013 textIn 2002, Feldman, Ilmanen, and Knopf constructed the first example of a non-trivial (i.e. non-constant curvature) complete non-compact shrinking soliton, and conjectured that it models a Ricci flow singularity forming on a closed four-manifold.

Sustainable Development, EarlyView.ABSTRACT User personas are important tools for user understanding in human‐computer interaction (HCI), and understanding how personas contribute to environmental sustainability across research and practice contexts is increasingly important. Our systematic review of 36 articles on persona research in environmental sustainability reveals four key ...

Analysis of Ricci flow on noncompact manifolds [PDF]
, 2013 textIn this dissertation, we present some analysis of Ricci flow on complete noncompact manifolds. The first half of the dissertation concerns the formation of Type-II singularity in Ricci flow on [mathematical equation]. For each [mathematical equation]
