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‐

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. $g(t)\equiv E$.

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 ...

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.

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

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.

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.

Genome Architecture and Speciation in Plants and Animals

Molecular Ecology, EarlyView.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.
