A kinematically Bifurcated Metamaterial for Integrated Logic Operation and Computing

Advanced Science, EarlyView.
A family of 2n‐side kinematic polygonal modules with n decoupled inputs and 2n extreme configurations via kinematic bifurcation is proposed. It allows integrating seven basic logic gates on a quadrilateral module. Moreover, a minimized Parallel Computing Sum of Products function is developed, enabling all 2‐bit arithmetic (including division ...

Design and Structural Transformations of Zinc(II) Knotted Cage Frameworks

Angewandte Chemie, EarlyView.
Systematic control over coordination environments and subcomponent sequences enabled the formation and stabilization of trefoil perplexanes and trefoil tetrahedral knotted cages. Peripheral crosslinkers diminished framework stability to tune host–guest behavior and dynamic exchange, while mechanical entanglement modulated self‐sorting and guest binding,

The driven-dissipative Bose–Hubbard dimer: phase diagram and chaos

New Journal of Physics, 2020
We present the phase diagram of the mean-field driven-dissipative Bose–Hubbard dimer model. For a dimer with repulsive on-site interactions ( U  > 0) and coherent driving, we prove that ${{\mathbb{Z}}}_{2}$ -symmetry breaking, via pitchfork bifurcations ...

Cusp points and pitchfork interactions in equivariant bifurcation problems

Differential and Integral Equations, 1993
The relation between the concept of a cusp point for a mapping between Banach spaces and the interaction of two classical pitchfork bifurcations in equivariant spaces is considered. 2 parameter problems are considered by an approach based on linear normal form theory, Lyapunov-Schmidt reduction and restriction to solutions with appropriate isotropies ...

Bifurcation analysis of a normal form for excitable media: Are stable dynamical alternans on a ring possible?

, 2008
We present a bifurcation analysis of a normal form for travelling waves in one-dimensional excitable media. The normal form which has been recently proposed on phenomenological grounds is given in form of a differential delay equation.

Durable Lithium Metal Anodes Enabled by {110}‐Textured Epitaxy on a LiF@Ag Commensurate Heterostructure

Advanced Science, EarlyView.
Utilizing their commensurate lattices, a LiF@Ag heterostructure is fabricated for Li epitaxy, featuring Ag nanoparticles grown on 2D LiF layers. The composition pinning effect inhibits Li‐Ag alloying and maintains the high lithiophilicity and fast adatom migration associated with Ag.

A Simple, Analytically Solvable, Chamberlinian Agglomeration Model [PDF]

This paper presents a simple Chamberlinian agglomeration model which, like the canonical core-periphery (CP) model, contains two agglomerative forces. However, in contrast to that model, the present model is analytically solvable.

Partial Reprogramming in Senescent Schwann Cells Enhances Peripheral Nerve Regeneration via Restoration of Stress Granule Homeostasis

Advanced Science, EarlyView.
In this study, it is discovered that pathological accumulation of Runx2+ Schwann cell clusters​ during axonal regeneration is a key factor impairing nerve repair in aging. This pathology is associated with ​dysregulation of stress granule homeostasis.

Nonlinear Magnetoconvection in a Sparsely Packed Porous Medium

International Journal of Geophysics, 2011
Linear and weakly nonlinear properties of magnetoconvection in a sparsely packed porous medium are investigated. We have obtained the values of Takens-Bogdanov bifurcation points and codimension two bifurcation points by plotting graphs of neutral curves

Bogdanov-Takens bifurcations in the enzyme-catalyzed reaction comprising a branched network

Mathematical Biosciences and Engineering, 2017
There have been some results on bifurcations of codimension one (such as saddle-node, transcritical, pitchfork) and degenerate Hopf bifurcations for an enzyme-catalyzed reaction system comprising a branched network but no further discussion for ...
