Dansgaard–Oeschger events: bifurcation points in the climate system [PDF]
Climate of the Past, 2013 Dansgaard–Oeschger events are a prominent mode of variability in the records of the last glacial cycle. Various prototype models have been proposed to explain these rapid climate fluctuations, and no agreement has emerged on which may be the more correct

Advanced Materials, EarlyView.Catalyst coordination acts as a loaded dice biasing reaction selectivity. Single‐atom site catalysts lock intermediates in exposed configurations, enabling continued hydrogenation and favoring oxygen‐retaining products. In contrast, extended metal surfaces fully coordinate and shield reactive centers, promoting deoxygenation pathways. This work reveals

On bifurcation points of strongly condensing operators
Научный вестник МГТУ ГА, 2016 Two conditions equivalent to complete continuity of Frechet derivative at a point and the asymptotic derivative in the case of their existence are given. Theorem of M.A. Krasnosel’skii on asymptotic bifurcation points for completely con-tinuous fields to

On the bifurcation analysis of thin multilayer structures by the Asymptotic Numerical Method [PDF]
Journal of Theoretical, Computational and Applied MechanicsThis paper focuses on the stability analysis of multilayer thin shells using the asymptotic numerical method (ANM) combined with Padé approximants. This technique is highly effective for solving nonlinear problems due to its high-order algorithm that ...

Limit values of the non-acyclic Reidemeister torsion for knots
, 2007 We consider the Reidemeister torsion associated with SL(2, C)-representations of a knot group. A bifurcation point in the SL(2, C)-character variety of a knot group is a character which is given by both an abelian SL(2, C)-representation and a non ...

Bistable Wetting States on a Smooth Surface
Advanced Materials Interfaces, EarlyView.Droplets on non‐textured surfaces typically exhibit a monostable wetting state. Here, we show that droplets can exhibit bistability even without surface texture. We investigate water droplets on a smooth substrate immersed in oil. We find that molecular modulation causes the droplet states to bifurcate into either a sticking or a repellent state ...

A global index for bifurcation of fixed points.
Journal für die reine und angewandte Mathematik (Crelles Journal), 1988 Let \(X\) be a Banach space, \(\mathcal O\subset\mathbb R^ k\times X\) be open and \(f: \mathcal O\to X\) be completely continuous such that \(f(\lambda,0)=0\) for all \(\lambda\). If the set \[ \mathcal B:=\mathbb R^ k\cap \text{clos}\{(\lambda,x)\in\mathcal O: f(\lambda,x)=x\neq 0 \} \] of bifurcation points is compact an index \(\mathrm{BI}(f)\) is ...
