Pseudolocality for the Ricci Flow and Applications [PDF]
Canadian Journal of Mathematics, 2011 Abstract Perelman established a differential Li-Yau-Hamilton (LYH) type inequality for fundamental solutions of the conjugate heat equation corresponding to the Ricci flow on compact manifolds. As an application of the LYH inequality, Perelman proved a pseudolocality result for the Ricci flow on compact manifolds. In this article we provide the details

Land Degradation &Development, EarlyView.ABSTRACT Global climate change poses unprecedented challenges for agricultural sustainability, yet significant knowledge gaps persist regarding the multidimensional impacts of climate policy uncertainty (CPU) on agricultural systems. Previous research has primarily focused on isolated aspects such as land‐use changes, production decisions, or emission ...

Ultrasound‐guided injections for the retrotrochanteric region: A cadaveric investigation
PM&R, EarlyView.Abstract Background Injections for the piriformis and triceps coxae tendons/bursae have not been described and validated. Objective To investigate the deep retrotrochanteric anatomy and validate an ultrasound (US)‐guided injection technique. Methods Fifteen sides of the pelvic half/lower limb of formalin‐fixed cadaveric specimens were dissected to ...

Charting cellular differentiation trajectories with Ricci flow
Nature CommunicationsComplex 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.

Driving SDG15: The Role of HEIs in Biodiversity Conservation Through Digitalization and Reporting
Sustainable Development, EarlyView.ABSTRACT Education, research, and public engagement are key strategies guiding European higher education institutions (HEIs) in advancing the United Nations Sustainable Development Goals (SDGs). Through stakeholder, legitimacy, and resource‐based view theories, this study examines the contributions of HEIs to saving Life on Land (SDG15), focusing on ...

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

United European Gastroenterology Journal, EarlyView.ABSTRACT Background The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) pandemic has highlighted the potential exacerbation of gastrointestinal symptoms in patients with disorders of gut‐brain interaction (DGBIs). However, the distinct symptom trajectories and psychological burden in patients with post‐COVID‐19 DGBIs compared with patients
