Predator–prey pattern formation driven by population diffusion based on Moore neighborhood structure
Diffusion-driven instability is a basic nonlinear mechanism for pattern formation. Therefore, the way of population diffusion may play a determinative role in the spatiotemporal dynamics of biological systems. In this research, we launch an investigation

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.

Turing Instability and Pattern Formation on Directed Networks
Pattern formation, arising from systems of autonomous reaction-diffusion equations, on networks has become a common topic of study in the scientific literature. In this work we focus primarily on directed networks. Although some work prior has been done to understand how patterns arise on directed networks, these works have restricted their attentions ...

Influence of the Turing instability on the motion of domain boundaries
Turing's theory of pattern formation has provided crucial insights into the behavior of various biological, geographical, and chemical systems over the last few decades. Existing studies have focused on moving-boundary Turing systems for which the motion of the boundary is prescribed by an external agent.

Prediction‐Based Algorithms for Long‐Range High‐Speed Force Spectroscopy
ABSTRACT We present a high‐speed force microscopy platform mounted on a confocal microscope with a z sample stage enabling long‐range, high‐speed force spectroscopy measurements on biological samples. The control software is built on a field‐programmable gate array (FPGA)‐based data acquisition and processing system, complemented with a custom ...

Placental ischemia in pre‐eclampsia initiates cytokine‐driven endothelial dysfunction, angiogenic imbalance, oxidative stress, and thromboinflammation. Elevated TNF‐α, IL‐6, IL‐17, sFlt‐1, and complement activation promote vasoconstriction, thrombosis, and cardiovascular instability.

Wavelength of a Turing-type mechanism regulates the morphogenesis of meshwork patterns
The meshwork pattern is a significant pattern in the development of biological tissues and organs. It is necessary to explore the mathematical mechanism of meshwork pattern formation.

Design and Fabrication of Complex Micro–Nano Structures for Osteogenesis Interfacing in 3D
The graphical abstract demonstrates the 3D Si structure platforms and the cell interactions. (left) Si structures including wine glass‐, obelisk‐, and pillar‐shaped structures are fabricated at wafer scale. (right) Compare to planar Si substrate, the wine glass‐shaped structures demonstrated promising cellular behavior and osteogenesis guidance by ...
