Global Ecology and Biogeography, Volume 35, Issue 10, October 2026.ABSTRACT Aim To determine the factors that structure coral‐associated microbial communities (bacteria and Symbiodiniaceae). These microbial communities play critical roles in reef ecosystem function, yet the relative importance of environmental versus geographic drivers in structuring these communities across large spatial scales remains poorly ...

, 2007 Let (Mn, g) be a Riemannian manifold. Say K ! E ! M is a principal K-bundle with connection A. We define a natural evolution equation for the pair (g,A) combining the Ricci flow for g and the Yang-Mills flow for A which we dub Ricci Yang-Mills flow ...

Ricci Solitons in β-Kenmotsu Manifolds
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 The object of the present paper is to study Ricci soliton in β-Kenmotsu manifolds. Here it is proved that a symmetric parallel second order covariant tensor in a β-Kenmotsu manifold is a constant multiple of the metric tensor.

New Phytologist, Volume 252, Issue 1, Page 260-275, October 2026.Maize regeneration via somatic embryogenesis by ectopic expression of morphogenic factors TaGRF4‐TaGIF1 and ZmBBM. Summary Transformation is an indispensable tool for plant genetics and functional genomics. Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic ...

Harmonic spinors in the Ricci flow
, 2022 This paper studies the Ricci flow on closed manifolds admitting harmonic spinors. It is shown that Perelman's Ricci flow entropy can be expressed in terms of the energy of harmonic spinors in all dimensions, and in four dimensions, in terms of the energy

The Journal of Physiology, Volume 604, Issue 19, Page 8069-8099, 1 October 2026.Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Magnetic Reconnection Driven by the Impact of a Magnetosheath High‐Speed Jet
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract High‐speed jets (HSJs) are transient structures in the magnetosheath characterized by enhanced dynamic pressure. While recent studies report that HSJs trigger magnetic reconnection at the magnetopause, whether they can directly drive reconnection within the magnetosheath remains an open question.

Polymer Composites, Volume 47, Issue 18, Page 16649-16665, 20 September 2026.Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.
