Communications on Pure and Applied Mathematics, EarlyView.Abstract Let (Mn,g)$(M^n,g)$ be a complete Riemannian manifold which is not isometric to Rn$\mathbb {R}^n$, has nonnegative Ricci curvature, Euclidean volume growth, and quadratic Riemann curvature decay. We prove that there exists a set G⊂(0,∞)$\mathcal {G}\subset (0,\infty)$ with density 1 at infinity such that for every V∈G$V\in \mathcal {G}$ there ...

Ricci curvatures on Hermitian manifolds
Transactions of the American Mathematical Society, 2017 In this paper, we introduce the first Aeppli-Chern class for complex manifolds and show that the ( 1 , 1 ) (1,1) -component of the curvature 2 2 -form of the Levi-Civita connection on the anti-canonical line bundle represents this class. We systematically investigate the relationship

Rigidity of cones with bounded Ricci curvature [PDF]
Journal of the European Mathematical Society, 2020 We show that the only metric measure space with the structure of an N -cone and with two-sided synthetic Ricci bounds is the Euclidean space \mathbb R^{N+1} for N integer.

Fragmentation of Multimodal Rectal Cancer Care: A Population‐Level Retrospective Cohort Study
Journal of Surgical Oncology, EarlyView.ABSTRACT Background Locally advanced rectal cancer is often treated with multimodal therapy. Patients may receive care at a single institution or across multiple institutions. We designed this population‐level retrospective cohort to determine the association between fragmented care and timeliness of treatment and long‐term oncologic outcomes.

Moderate Laryngeal Dysplasia in the Context of Classification Systems and Clinical Decision Making
The Laryngoscope, EarlyView.There is still an ongoing debate about the classification of laryngeal dysplasia. In a large retrospective analysis of 392 patients, the progression of dysplasia and the risk of a de novo occurrence of invasive carcinoma were evaluated. Here especially the high rate of occurrence of invasive carcinoma in the group of moderate dysplasia with 44% is of ...

AIMS MathematicsThe Ricci curvature in Finsler geometry naturally generalizes the Ricci curvature in Riemannian geometry. In this paper, we study the -th root metric with weakly isotropic scalar curvature and obtain that its scalar curvature must vanish.

Stability of China’s Stock Market: Measure and Forecast by Ricci Curvature on Network
Complexity, 2023 The systemic stability of a stock market is one of the core issues in the financial field. The market can be regarded as a complex network whose nodes are stocks connected by edges that signify their correlation strength.

Polymer Composites, EarlyView.Production process of amine‐modified silica aerogel reinforced aramid/epoxy composite (EAFS). ABSTRACT Due to its high pore size and low density, amine‐modified silica aerogel (XSA) is an excellent candidate for the secondary reinforcement material of polymer matrix composites.
