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.

Bifurcations and Transitions to Chaos in An Inverted Pendulum
, 1998 We consider a parametrically forced pendulum with a vertically oscillating suspension point. It is well known that, as the amplitude of the vertical oscillation is increased, its inverted state (corresponding to the vertically-up configuration) undergoes

Advanced Theory and Simulations, EarlyView.Computational fluid dynamics analyses assess the upstream locomotion performance of anisotropic microrollers with varying height‐to‐width ratios. Observing their successful upstream locomotion in veins, their performance in hepatic circulation is investigated for treating primary liver cancer.

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 ...

Early‐Warning Signals for Critical Temperature Transitions
Geophysical Research Letters, 2020 Critical transitions of the state variable (temperature) in dynamic climate systems often lead to catastrophic consequence, whereas the effort to reverse the transitions usually lags behind.

Discrete Breathers in a Nonlinear Polarizability Model of Ferroelectrics
, 2011 We present a family of discrete breathers, which exists in a nonlinear polarizability model of ferroelectric materials. The core-shell model is set up in its non-dimensionalized Hamiltonian form and its linear spectrum is examined.

Enhanced Media Optimize Bovine Myogenesis in 2D and 3D Models for Cultivated Meat Applications
Advanced Science, EarlyView.This study uses multiomics approaches to characterize bovine myogenesis in vitro, identifying media components that enhance myogenic progenitor cell differentiation in 2D and 3D models. Notably, the enhanced conditions promoted formation of unique cell populations and contractile muscle cells expressing mature myogenic markers.

International Journal of Applied Mechanics and Engineering, 2016 In this paper, we investigate the combined effect of internal heating and time periodic gravity modulation in a viscoelastic fluid saturated porous medium by reducing the problem into a complex non-autonomous Ginzgburg-Landau equation.

Signatures of classical bifurcations in the quantum scattering resonances of dissociating molecules
, 2014 A study is reported of the quantum scattering resonances of dissociating molecules using a semiclassical approach based on periodic-orbit theory. The dynamics takes place on a potential energy surface with an energy barrier separating two channels of ...
