Small-angle scattering from fat fractals

open access: yes, 2014
A number of experimental small-angle scattering (SAS) data are characterized by a succession of power-law decays with arbitrarily decreasing values of scattering exponents.

Design and characterization of electrons in a fractal geometry [PDF]

open access: yesNature Physics, 2018
The dimensionality of an electronic quantum system is decisive for its properties. In one dimension, electrons form a Luttinger liquid, and in two dimensions, they exhibit the quantum Hall effect.

Fractal Dimension of Particle Showers Measured in a Highly Granular Calorimeter

open access: yes, 2013
We explore the fractal nature of particle showers using Monte-Carlo simulation. We define the fractal dimension of showers measured in a high granularity calorimeter designed for a future lepton collider.

Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Decomposition of Heart Rate Variability Spectrum into a Power-law Function and a Residual Spectrum

open access: yesFrontiers in Cardiovascular Medicine, 2016
The power spectral density (PSD) of heart rate variability (HRV) contains a power-law relationship that can be obtained by plotting the logarithm of PSD against the logarithm of frequency.

Direct Ink Writing of Carbon‐Based Electrofluids for Soft Electrical Component Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
This work explores the manufacturing of Electrofluids (EFs), conductive particle suspensions that flow while maintaining conductivity, for soft electrical components. Using Direct Ink Writing (DIW), patterned EFs achieve enhanced performance, including a 800% sensitivity boost in strain gauges. Through rheological studies, a printability map is created

Structural properties of fractals with positive Lebesgue measures

open access: yes, 2015
Small-angle scattering (SAS) data which show a succession of power-law decays with decreasing values of scattering exponents, can be described in terms of fractal structures with positive Lebesgue measure (fat fractals).
