Hybrid Reaction–Diffusion Epidemic Models: Dynamics and Emergence of Oscillations
ABSTRACT In this paper, we construct a hybrid epidemic mathematical model based on a reaction–diffusion system of the SIR (susceptible‐infected‐recovered) type. This model integrates the impact of random factors on the transmission rate of infectious diseases, represented by a probabilistic process acting at discrete time steps.

Simulation numérique d'un bruleur à biogaz destiné aux moteurs Stirling
The design of a biogas burner for Stirling engines depends on its ability to provide a sufficient heat which is not produced by conventional burners because of the limitation of the contact surface between flame-hot head and the low methane content in ...

This article examines how emerging generative AI technologies in Europe and North America are being used to reanimate the dead, prompting users to define the ‘edges’ of self and personhood through coding practices. These technologies invite new engagements with fundamental questions of relatedness and the construction of the self, challenging and ...

Scale‐robust fibre orientation analysis of hair using two‐dimensional Fourier transform
We present a simple and robust method to quantify hair fibre orientation using 2D‐DFT. It works with standard images and extracts directional features at multiple scales. This enables objective evaluation of cosmetic treatments and product effects. Abstract Objective To address the current lack of standardized tools for evaluating hair appearance in ...

The Role of Near Solstice Solar Radiation on the Pacific Northwest Heatwave of June 2021
Abstract In late June 2021, the Pacific Northwest experienced a severe heatwave, shattering temperature records and making worldwide news. The extreme temperatures have been attributed to an anomalously strong atmospheric block, high moisture content of upstream air, and dry soils.

Sub‐THz Multifunctional Metasurfaces for Independent Transmission or Reflection Phase Manipulation
This article presents a rigorous analysis, design, and characterization of a novel sub‐THz metalens and reflective metasurface. Unlike bulky optical systems, the proposed thin, planar metasurface enables dual‐band full‐space wavefront control, via low‐loss transmission and reflection phase tuning, offering compact integration and improved ...
