New promises and future challenges of fractal calculus: From two-scale thermodynamics to fractal variational principle

open access: yes, 2020
Any physical laws are scale-dependent, the same phenomenon might lead to debating theories if observed using different scales. The two-scale thermodynamics observes the same phenomenon using two different scales, one scale is generally used in the ...

Switched-capacitor-convertors based on fractal design for output power management of triboelectric nanogenerator

open access: yesNature Communications, 2020
Owing to the advantages of integration and being magnet-free and light-weight, the switched-capacitor-convertor plays an increasing role compared to traditional transformer in some specific power supply systems.

Effect of psychoacoustic annoyance on EEG signals of tractor drivers [PDF]

open access: yesArchives of Acoustics, 2022
The purpose of this study was to evaluate the psychoacoustic annoyance (PA) that the tractor drivers are exposed to, and investigate its effects on their brain signals during their work activities. To this aim, the sound of a garden tractor was recorded.

Effect of Heterogeneity in Initial Geographic Distribution on Opinions’ Competitiveness

open access: yesEntropy, 2015
Spin dynamics on networks allows us to understand how a global consensus emerges out of individual opinions. Here, we are interested in the effect of heterogeneity in the initial geographic distribution of a competing opinion on the competitiveness of ...

Evaluating social learning in participatory mapping of ecosystem services

open access: yesEcosystems and People, 2019
Recent studies have shown the opportunities and limitations of participatory mapping for ecosystem services management, although it is an incipient research area. One of the research questions yet to be addressed is whether the composition of stakeholder

Fractal Analytical Approach of Urban Form Based on Spatial Correlation Function [PDF]

open access: yesChaos, Solitons & Fractals, 2013, 49: 47-60, 2012
Urban form has been empirically demonstrated to be of scaling invariance and can be described with fractal geometry. However, the rational range of fractal dimension value and the relationships between various fractal indicators of cities are not yet revealed in theory. By mathematical deduction and transformation (e.g.

The Potential of Biophilic Fractal Designs to Promote Health and Performance: A Review of Experiments and Applications

open access: yesSustainability, 2021
Fractal objects are prevalent in natural scenery. Their repetition of patterns at increasingly fine magnifications creates a rich complexity. Fractals displaying mid-range complexity are the most common and include trees, clouds, and mountains.

Fractal dynamics in physiology: Alterations with disease and aging

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2002
According to classical concepts of physiologic control, healthy systems are self-regulated to reduce variability and maintain physiologic constancy. Contrary to the predictions of homeostasis, however, the output of a wide variety of systems, such as the
