Numerical unfoldings of codimension-three resonant homoclinic flip bifurcations [PDF]
The paper presents a careful numerical study of two homoclinic codimension-three bifurcations. In these resonant homoclinic flip bifurcations both a resonance between real eigenvalues and some codimension-two flip bifurcation (inclination flip or orbit flip) occur simultaneously.

The crystal structures of Arabidopsis thaliana γ‐glutamyl peptidase 1 (GGP1), including the covalent intermediate state, were determined. GGP1 is involved in both glutathione degradation in the primary metabolism and glutathione conjugate processing in the secondary metabolism of glucosinolate and camalexin biosynthesis.

In this paper, bifurcations and chaotic behaviours of Kopel oligopoly model with different adjustment speed are discussed. The results imply that the Kopel oligopoly model undergoes flip bifurcation, Neimark–Sacker bifurcation, 1:3 and 1:4 resonances ...

Resonant homoclinic flip bifurcations: a numerical investigation [PDF]
We report on a numerical study of codimension-three resonant inclination flip homoclinic orbits. Two cases of unfoldings are presented: one with a single homoclinic doubling, and the other containing a homoclinic-doubling cascade. Our results confirm the unfoldings given in (A.J. Homburg and B.

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry
ABSTRACT The global pesticide industry transformed from one dominated by patented products and legacy multinationals with strong manufacturing bases in the United States and EU to one dominated by generic products produced in India and China. We use proprietary market research data, data from regulatory filings, industry press and bilateral trade data ...

Morphology transition at depinning in a solvable model of interface growth in a random medium
We propose a simple, exactly solvable, model of interface growth in a random medium that is a variant of the zero-temperature random-field Ising model on the Cayley tree.

Finding Stars: Mapping the Geography of the World's Scientific Elites
Short Abstract Scientific excellence is clustering ever more tightly in a few ‘superstar’ cities. Four—New York, Boston, London and the San Francisco Bay Area—now host 12% of the world's top scientists. In contrast, the Global South remains largely absent, with the notable exception of Beijing's dramatic rise.

Bifurcations and chaos in a three-dimensional generalized Hénon map
This article presents the bifurcation and chaos phenomenon of the three-dimensional generalized Hénon map. We establish the existence and stability conditions for the fixed points of the system.

Ghost effect from Boltzmann theory
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...
