Revolving fractals [PDF]

open access: yesJournal of Fractal Geometry, Mathematics of Fractals and Related Topics, 2021
Davis and Knuth in 1970 introduced the notion of revolving sequences, as representations of a Gaussian integer. Later, Mizutani and Ito pointed out a close relationship between a set of points determined by all revolving sequences and a self-similar set, which is called the Dragon.

Controlling long-term SARS-CoV-2 infections can slow viral evolution and reduce the risk of treatment failure

open access: yesScientific Reports, 2021
The rapid emergence and expansion of novel SARS-CoV-2 variants threatens our ability to achieve herd immunity for COVID-19. These novel SARS-CoV-2 variants often harbor multiple point mutations, conferring one or more evolutionarily advantageous traits ...

Time- and cost-effective production of untagged recombinant MVA by flow virometry and direct virus sorting

open access: yesJournal of Translational Medicine, 2023
Background Recombinant MVAs (rMVAs) are widely used both in basic and clinical research. Our previously developed Red-to-Green Gene Swapping Method (RGGSM), a cytometry-based Cell-Sorting protocol, revolves around the transient expression of a green ...

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.

Fractal Nanotechnology [PDF]

open access: yesNanoscale Research Letters, 2008
Abstract Self-similar patterns are frequently observed in Nature. Their reproduction is possible on a length scale 102–105 nm with lithographic methods, but seems impossible on the nanometer length scale. It is shown that this goal may be achieved via a multiplicative variant of the multi-spacer patterning technology, in this way permitting ...
