Event-Triggered Dissipative Filtering for Network-Based Stochastic Genetic Regulatory Networks Under Aperiodic Sampling

IEEE Access, 2020
Based on event-triggered mechanism, networked dissipative filtering of stochastic genetic regulatory networks is investigated under aperiodic sampling.

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

From the Fibonacci Icosagrid to E₈ (Part II): The Composite Mapping of the Cores

Crystals
This paper is part of a series that describes the Fibonacci icosagrid quasicrystal (FIG) and its relation to the E8 root lattice. The FIG was originally constructed to represent the intersection points of an icosahedrally symmetric collection of planar ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

Angewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.

Freeform Light Routing in Nearly‐Hyperuniform Slabs: Toward a General‐Purpose Design Platform for Integrated Photonics

Advanced Optical Materials, EarlyView.
Nearly hyperuniform disordered photonic slabs guide light along prescribed freeform pathways without relying on lattice symmetry. A pathway‐first design embeds curved channels within a photonic bandgap hyperuniform network, maintaining high transmission through freeform bends.

Towards aperiodic tesellation: a self-organising particle spring system approach [PDF]

, 2008
The derivation of novel programming methods for the generation of aperiodic tiling patterns, predominantly in 2d space, has attracted considerable attention from both researchers and practicing architects.

Regularity of aperiodic minimal subshifts

Bulletin of Mathematical Sciences, 2017
At the turn of this century Durand, and Lagarias and Pleasants established that key features of minimal subshifts (and their higher-dimensional analogues) to be studied are linearly repetitive, repulsive and power free.
