Turing instability and Hopf bifurcation in a predator–prey model with delay and predator harvesting
Advances in Difference Equations, 2019 In this paper, we study a predator–prey model with delay and harvesting on predator. We give the conditions for stability and Turing instability of coexisting equilibrium by analyzing the eigenvalue spectrum.

Conceptualizing Utu as a Foreign Policy Doctrine for Aotearoa New Zealand
Global Policy, Volume 16, Issue 4, Page 568-578, September 2025.ABSTRACT During Nanaia Mahuta's tenure as New Zealand's Foreign Minister (2020–2023), Aotearoa New Zealand experimented with a foreign policy guided by four tikanga (Māori customary practices), namely, manaakitanga (hospitality), whanaungatanga (connectedness), mahi tahi and kotahitanga (unity through collaboration), and kaitiakitanga ...

Discrete Dynamics in Nature and Society, 2020 The reaction diffusion system is one of the important models to describe the objective world. It is of great guiding importance for people to understand the real world by studying the Turing patterns of the reaction diffusion system changing with the ...

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12011-12037, August 2025.ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.

Water Resources Research, Volume 61, Issue 8, August 2025.Abstract The length of hillslope flowpaths plays a crucial role in various hydrological, geomorphological and ecological processes. However, hillslope lengths change as the flowing network expands or contracts in response to precipitation. Currently, there is limited understanding of how channel network dynamics influence the distribution of hillslope ...

Analysis of dynamic properties on forest restoration-population pressure model
Mathematical Biosciences and Engineering, 2020 On the basis of logistic models of forest restoration, we consider the influence of population pressure on forest restoration and establish a reaction diffusion model with Holling II functional responses.

International Migration, Volume 63, Issue 4, August 2025.ABSTRACT This article argues that there is no single form of security that reduces insecurity but rather forms of (in)security that are contradictory and mutually destructive. This is the case between traditional liberal security, based on evidence, the individual and the penal order, and contemporary predictive preventive security, based on ...

A Nonlinear Cross-Diffusion Model for Disease Spread: Turing Instability and Pattern Formation
MathematicsIn this article, we propose a novel nonlinear cross-diffusion framework to model the distribution of susceptible and infected individuals within their habitat using a reduced SIR model that incorporates saturated incidence and treatment rates.

Spatial Complexity of a Predator-Prey Model with Holling-Type Response
Abstract and Applied Analysis, 2014 We focus on a spatially extended Holling-type IV predator-prey model that contains some important factors, such as noise (random fluctuations), external periodic forcing, and diffusion processes.
