Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, EarlyView.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

Mean-field games for high-density crowds: The discount factor reproduces experiments but raises numerical issues [PDF]

EPJ Web of Conferences
Among the various types of crowd models, mean-field games have proved especially appropriate to reproduce some experimental results in high density crowds that involve anticipation on a time scale longer than usually involved in collision avoidance.

A Smart Magnetically Actuated Flip‐Disc Programmable Metasurface with Ultralow Power Consumption for Real‐Time Channel Control

Advanced Functional Materials, EarlyView.
The study proposes a 1‐bit programmable metasurface based on flip‐disc display, named flip‐disc metasurface (FD‐MTS). This new design enables ultralow energy consumption while maintaining coding patterns. It also exhibits high scalability and multifunctional flexibility.

Linear-quadratic-Gaussian mean-field games driven by Poisson jumps with major and minor agents

AIMS Mathematics
This paper studies mean-field linear-quadratic-Gaussian (LQG) games with a major agent and a large number of minor agents, where each agent's state process is driven by a Poisson random measure and independent Brownian motion.

Laser‐Based Sculpturing of Embedded Ultrathin Metal‐Oxide Nanopores for Enhanced Biomolecular Sensing

Advanced Functional Materials, EarlyView.
Controlled laser‐drilling of embedded HfO2 membranes creates three layer nanopores with Gaussian‐shaped cavities sculptured in the supporting layers. These embedded solid‐state nanopores slow DNA translocation by 12‐fold compared to SiNx pores, enabling high‐resolution, label‐free detection of short DNAs, RNAs, and proteins.

Mean-Field Modeling of Green Technology Adoption: A Competition for Incentives

Mathematics
This paper investigates the role of fiscal incentives in promoting the transition to a green economy using a dynamic mean-field game framework. By modeling firms as representative agents undergoing an environmentally sustainable transition, we analyze ...
