Pattern Formation Mechanisms of Spatiotemporally Discrete Activator–Inhibitor Model with Self- and Cross-Diffusions

Fractal and Fractional
In this paper, we aim to solve the issue of pattern formation mechanisms in a spatiotemporally discrete activator–inhibitor model that incorporates self- and cross-diffusions.

Economic integration and agglomeration in a customs union in the presence of an outside region [PDF]

, 2012
New Economic Geography (NEG) models do not typically account for the presence of regions other than the ones involved in the integration process. We explore such a possibility in a Footloose Entrepreneur (FE) model aiming at studying the stability ...

Infrared Devices Versus Traditional Palpation Approach for Peripheral Intravenous Catheter Insertion in Adults: A Systematic Review and Meta‐Analysis

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aims This systematic review and meta‐analysis evaluated the efficacy of infrared (IR) devices versus the traditional palpation technique for first‐attempt success of peripheral intravenous catheter (PIVC) insertion in adults. Design Systematic review and meta‐analysis of randomised controlled trials (RCTs).

Controlling the chaos and bifurcations of a discrete prey-predator model

AIMS Mathematics
In this paper, we explore the existence of fixed points, local dynamics at fixed points, bifurcations and chaos of a discrete prey-predator fishery model with harvesting.

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry

Journal of Agrarian Change, EarlyView.
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 ...

Research on Stability and Bifurcation for Two-Dimensional Two-Parameter Squared Discrete Dynamical Systems

Mathematics
This study investigates a class of two-dimensional, two-parameter squared discrete dynamical systems. It determines the conditions for local stability at the fixed points for these proposed systems.

Dynamics analysis for a discrete dynamic competition model

Advances in Difference Equations, 2019
In this paper, the dynamics of a discrete market share attraction model are investigated. It shows that the system can undergo flip bifurcation and chaos.

Subthreshold oscillations in a map-based neuron model

, 2004
Self-sustained subthreshold oscillations in a discrete-time model of neuronal behavior are considered. We discuss bifurcation scenarios explaining the birth of these oscillations and their transformation into tonic spikes.

Muslim women's agency; getting past the binary trap

Sociological Forum, EarlyView.
Abstract Although feminist theorizing on Muslim women's agency has come a long way, recent models reflect a one‐dimensional conception of agency that reinvigorates problematic binaries and undermines feminist politics. To address these limitations, the author focuses on the interpersonal arena where agency involves not only doing but also the ...
