Fixed-Parameter Extrapolation and Aperiodic Order

, 2012
Fix any $ \in\mathbb{C}$. We say that a set $S\subseteq\mathbb{C}$ is $ $-$convex$ if, whenever $a$ and $b$ are in $S$, the point $(1- )a+ b$ is also in $S$. If $S$ is also (topologically) closed, then we say that $S$ is $ $-$clonvex$. We investigate the properties of $ $-convex and $ $-clonvex sets and prove a number of facts about them ...

EEG Fingerprints under Naturalistic Viewing Using a Portable Device

Sensors, 2020
The electroencephalogram (EEG) has been proven to be a promising technique for personal identification and verification. Recently, the aperiodic component of the power spectrum was shown to outperform other commonly used EEG features.

Task-related, intrinsic oscillatory and aperiodic neural activity predict performance in naturalistic team-based training scenarios

Scientific Reports, 2022
Effective teams are essential for optimally functioning societies. However, little is known regarding the neural basis of two or more individuals engaging cooperatively in real-world tasks, such as in operational training environments.

Rapid adaptation of predictive models during language comprehension: Aperiodic EEG slope, individual alpha frequency and idea density modulate individual differences in real-time model updating

Frontiers in Psychology, 2022
Predictive coding provides a compelling, unified theory of neural information processing, including for language. However, there is insufficient understanding of how predictive models adapt to changing contextual and environmental demands and the extent ...

Fractional Transport of Photons in Deterministic Aperiodic Structures

Scientific Reports, 2017
The propagation of optical pulses through primary types of deterministic aperiodic structures is numerically studied in time domain using the rigorous transfer matrix method in combination with analytical fractional transport models.

From the Fibonacci Icosagrid to E₈ (Part I): The Fibonacci Icosagrid, an H₃ Quasicrystal

Crystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...
