Ricci ϕ-invariance on almost cosymplectic three-manifolds
Open Mathematics, 2023 Let M3{M}^{3} be a strictly almost cosymplectic three-manifold whose Ricci operator is weakly ϕ\phi -invariant. In this article, it is proved that Ricci curvatures of M3{M}^{3} are invariant along the Reeb flow if and only if M3{M}^{3} is locally ...

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Advanced Functional Materials, EarlyView.Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Propagation of symmetries for Ricci shrinkers
Advanced Nonlinear Studies, 2023 We will show that if a gradient shrinking Ricci soliton has an approximate symmetry on one scale, this symmetry propagates to larger scales. This is an example of the shrinker principle which roughly states that information radiates outwards for ...

On the Conditions to Extend Ricci Flow [PDF]
International Mathematics Research Notices, 2008 We develop some estimates under the Ricci flow and use these estimates to study the blowup rates of curvatures at singularities. As applications, we obtain some gap theorems: $\displaystyle \sup_X |Ric|$ and $\displaystyle \sqrt{\sup_X |Rm|} \cdot \sqrt{\sup_X |R|}$ must blowup at least at the rate of type-I.

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box
Advanced Science, EarlyView.High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

American Journal of Hematology, EarlyView.ABSTRACT We analyzed 193 Fanconi anemia patients from the Italian Registry, focusing on hematological outcome, cancer risk, and mortality, both in transplanted (n = 130, 67.4% of the cohort) and non‐transplanted (n = 63, 36.6% of the cohort) patients. After a median follow‐up of 7 years, almost all patients developed cytopenia that was more frequent in

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.

The conical K\"ahler-Ricci flow on Fano manifolds [PDF]
, 2015 In this paper, we study the long-term behavior of the conical K\"ahler-Ricci flow on Fano manifold $M$. First, based on our work of locally uniform regularity for the twisted K\"ahler-Ricci flows, we obtain a long-time solution to the conical K\"ahler ...
