Robustness of Spontaneous Polarization Through Nonlinear Directional Antagonism Without Global Inhibition

open access: yesJournal of the Chinese Chemical Society, EarlyView.
The conventional “local activation–global inhibition” (LAGI) models utilize mean‐field averaging inhibition to suppress distant activations. As the inhibition diminishes with distance, LAGI models struggle to achieve robust single‐axis polarity in large systems.

Local Search and the Evolution of World Models

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Bifurcation, Chaos, and Pattern Formation for the Discrete Predator-Prey Reaction-Diffusion Model

open access: yesDiscrete Dynamics in Nature and Society, 2019
In this paper, a discrete predator-prey system with the periodic boundary conditions will be considered. First, we get the conditions for producing Turing instability of the discrete predator-prey system according to the linear stability analysis.

Characterising City Scale Heat Climatology for Australian Climate Zones

open access: yesInternational Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

Dynamics of a Diffusive Predator-Prey Model with Allee Effect on Predator

open access: yesDiscrete Dynamics in Nature and Society, 2013
The reaction-diffusion Holling-Tanner prey-predator model considering the Allee effect on predator, under zero-flux boundary conditions, is discussed. Some properties of the solutions, such as dissipation and persistence, are obtained.

Should Dermatologists Recommend Direct‐to‐Consumer App‐Based Remote Diagnostics? An Ethical Analysis

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Dermatology patients still face barriers in accessing timely specialist care. As direct‐to‐consumer (DTC) apps for remote dermatological diagnostics proliferate, guidance is lacking. While promising efficiency and efficacy, their clinical—and ethical—legitimacy is not yet well established.

A Nonlinear Cross-Diffusion Model for Disease Spread: Turing Instability and Pattern Formation

open access: yesMathematics
In 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.

Noise–Seeded Developmental Pattern Formation in Filamentous Cyanobacteria

open access: yesLife, 2018
Under nitrogen-poor conditions, multicellular cyanobacteria such as Anabaena sp. PCC 7120 undergo a process of differentiation, forming nearly regular, developmental patterns of individual nitrogen-fixing cells, called heterocysts, interspersed between ...

Artificial Intelligence, Economic Decision‐Making, and Air Transport Performance: Evidence From G7 Countries

open access: yesManagerial and Decision Economics, EarlyView.
ABSTRACT This paper examines the role of artificial intelligence (AI) in shaping economic decision‐making and improving air transport performance in G7 countries over the period 1996–2021. AI is proxied by scientific publications and interpreted as an indicator of innovation capacity that supports data‐driven decision‐making and operational efficiency ...
