Topological Signals of Singularities in Ricci Flow
Axioms, 2017 We implement methods from computational homology to obtain a topological signal of singularity formation in a selection of geometries evolved numerically by Ricci flow.

Regularity of the Kähler–Ricci flow [PDF]
Comptes Rendus. Mathématique, 2013 In this short note, we announce a regularity theorem for the Kähler–Ricci flow on a compact Fano manifold (Kähler manifold with positive first Chern class) and its application to the limiting behavior of the Kähler–Ricci flow on Fano 3-manifolds. Moreover, we also present a partial C0 estimate of the Kähler–Ricci flow under the regularity assumption ...

PM&R, EarlyView.Abstract Objective To assess the potential prognostic role of sonographic parameters such as glenohumeral joint effusion, subacromial‐subdeltoid bursitis, and the type of intratendinous calcific deposition to predict the clinical and functional outcomes of focal extracorporeal shockwave therapy (fESWT) in patients with calcific tendinopathy of the ...

Unique Asymptotics of Compact Ancient Solutions to Three‐Dimensional Ricci Flow [PDF]
, 2019 We consider compact ancient solutions to the three-dimensional Ricci flow which are noncollapsed. We prove that such a solutions is either a family of shrinking round spheres, or it has a unique asymptotic behavior as $t \to -\infty$ which we describe ...

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production
PLANTS, PEOPLE, PLANET, EarlyView.Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

MathematicsIn this paper, we study the topology of steady gradient Ricci solitons with nonnegative sectional curvature. We apply a characterization theorem for the fundamental group of a positively curved steady gradient Ricci soliton that admits a critical point ...

Frontiers in Physics, 2022 The goal of the present study is to study the ∗-η-Ricci soliton and gradient almost ∗-η-Ricci soliton within the framework of para-Kenmotsu manifolds as a characterization of Einstein metrics.

River Research and Applications, EarlyView.ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter ks in a shallow‐water equation model (via the momentum ...
