Regularising the Ricci Flow Embedding [PDF]

open access: yes, 2010
This paper concerns the analysis of patterns that are specified in terms of non-Euclidean dissimilarity or proximity rather than ordinal values. In prior work we have reported a means of correcting or rectifying the similarities so that the non-Euclidean artifacts are minimized.

OsFeSOD3 Functions as an Enzymatic Component of the PEP Complex, Bifunctionally Regulating Chloroplastic ROS Metabolism and Chloroplast Biogenesis in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Chloroplasts are essential organelles responsible for photosynthesis, providing energy and metabolic intermediates required for plant growth and productivity. Chloroplast development is highly sensitive to environmental stresses such as drought, and this sensitivity is closely associated with growth inhibition and yield reduction under stress ...

Combinatorial Ricci Flows on Surfaces

open access: yesJournal of Differential Geometry, 2003
We show that the analog of Hamilton's Ricci flow in the combinatorial setting produces solutions which converge exponentially fast to Thurston's circle packing on surfaces. As a consequence, a new proof of Thurston's existence of circle packing theorem is obtained. As another consequence, Ricci flow suggests a new algorithm to find circle packings.

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

open access: yesR&D Management, EarlyView.
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 ...

A note on the Cotton flow and the Ricci flow for three-manifolds, and the Hořava–Lifshitz gravity

open access: yesEuropean Physical Journal C: Particles and Fields
We consider the more general geometrical flow in the space of metrics for three-manifolds that consists of a combination of two flows, the Cotton flow and the Ricci flow; by playing a fundamental role in the detailed balance principle of the four ...

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

open access: yesExperimental Physiology, EarlyView.
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
