The Ricci flow and the early universe

Annals of Physics, 2023
A framework of quantum spacetime reference frame is proposed and reviewed, in which the quantum spacetime at the Gaussian approximation is deformed by the Ricci flow. At sufficient large scale, the Ricci flow not only smooths out local small irregularities making the universe a homogeneous and isotropic Friedmann-Robertson-Walker metric, but also ...

Development of a highly active engineered PETase enzyme for polyester degradation

The FEBS Journal, EarlyView.
Polyethylene terephthalate (PET) accounts for approximately 6% of global plastic production and is a major contributor to plastic pollution. Enzymatic recycling offers a promising solution, but current PET‐degrading enzymes often lack sufficient thermostability and catalytic efficiency. Through in silico design, we engineered a more robust variant, LCC‐

Some New Characterizations of Trivial Ricci–Bourguignon Solitons

Journal of Mathematics
A Ricci–Bourguignon soliton is a self-similar solution to the Ricci–Bourguignon flow equation, and a Ricci–Bourguignon soliton is called trivial if its potential field is zero or killing.

A note on Kähler–Ricci flow

Mathematische Zeitschrift, 2011
Let $g(t)$ with $t\in [0,T)$ be a complete solution to the Kaehler-Ricci flow: $\frac{d}{dt}g_{i\bar j}=-R_{i\bar j}$ where $T$ may be $\infty$. In this article, we show that the curvatures of $g(t)$ is uniformly bounded if the solution $g(t)$ is uniformly equivalet.

IMPLICIT COMPARISONS: VISUALITY AND THE INTERLINEAR MANUSCRIPT PAGE

History and Theory, EarlyView.
ABSTRACT A central question for European philology, informed by various agendas and ideologies, concerned comparison and the positing of hierarchies among languages. With this “traditional” question of philology in mind, but hoping to think in less traditional ways, this article asks how comparative understandings of Arabic and local languages of the ...

Implementation of the ‘Countdown to Theatre’ Approach to Bridge the Evidence–Practice Gap in Paediatric Preoperative Fasting: A Quality Improvement Initiative

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim To evaluate the ‘Countdown to Theatre’ intervention, a co‐designed nurse‐led approach developed using the COM‐B framework to address context‐specific barriers and facilitators to preoperative fasting practices. Design A prospective mixed‐method, pre–post study assessed the intervention's impact on fasting adherence and patient experience ...

Psychological and Clinical Factors Mediate Post‐COVID‐19 Irritable Bowel Syndrome

Neurogastroenterology &Motility, EarlyView.
ABSTRACT Background Exposure to COVID‐19 has been shown previously to be associated with a higher risk for irritable bowel syndrome (IBS). This study aimed to better explain this relationship using mediation analysis. Methods This post hoc analysis of a multicenter cohort study includes 623 patients with and without COVID‐19 infection.

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.

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

R&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 ...
