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.

Collapsing immortal Kähler-Ricci flows
Forum of Mathematics, PiWe consider the Kähler-Ricci flow on compact Kähler manifolds with semiample canonical bundle and intermediate Kodaira dimension, and show that the flow collapses to a canonical metric on the base of the Iitaka fibration in the locally smooth topology ...

Communications in Mathematical Physics, 2007 In this paper, we study the change of the ADM mass of an ALE space along the Ricci flow. Thus we first show that the ALE property is preserved under the Ricci flow. Then, we show that the mass is invariant under the flow in dimension three (similar results hold in higher dimension with more assumptions).

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. All participants

The crop wild relative Fragaria vesca as source of resistance against strawberry anthracnose
Plant Biology, EarlyView.The crop wild relative Fragaria vesca is a valuable resource to mine for novel resistance factors against Colletotrichum. Abstract The genetic diversity of Fragaria species in situ has great potential for breeding resistance in cultivated strawberries against anthracnose disease.

Forman-Ricci Flow for Change Detection in Large Dynamic Data Sets
Axioms, 2016 We present a viable geometric solution for the detection of dynamic effects in complex networks. Building on Forman’s discretization of the classical notion of Ricci curvature, we introduce a novel geometric method to characterize different types of real-

The Ricci flow on manifolds with boundary [PDF]
Journal of Differential Geometry, 2016 Improved exposition and statement on the control of the existence time of the Ricci flow, and updated/added some references. Also, a new section is added, demonstrating a situation in which the existence time of the Ricci flow (with boundary) with flat initial data and well behaved boundary data may become arbitrarily ...
