Исследование бифуркационных диаграмм дробной динамической системы Селькова для описания автоколебательных режимов микросейсм

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
В статье исследуется динамические режимы дробной системы Селькова с переменной наследственностью (памятью). Эффект переменной наследственности означает, что наследственность изменяется во времени, т.е. зависимость текущего состояния системы от предыдущих

Plasma Diffuse Reflectance Infrared Fourier Transform Spectroscopy Cell Design and Experimental Set‐Up for Operando‐DRIFTS Investigations on Plasma‐Induced Heterogeneous Catalyzed Reactions

open access: yesChemistry–Methods, Volume 5, Issue 10, October 2025.
A customized apparatus for operando plasma‐diffuse reflectance infrared Fourier transform spectroscopy is developed by modifying the dome of a commercially available Harrick reaction chamber. The designed high‐voltage electrode is mounted and attached within a cylindrical holder made of PEEK.

Acoustic Characteristics of Stridor in Multiple System Atrophy. [PDF]

open access: yesPLoS ONE, 2016
Nocturnal stridor is a breathing disorder prevalent in patients with multiple system atrophy (MSA). An improved understanding of this breathing disorder is essential since nocturnal stridor carries a poor prognosis (an increased risk of sudden death). In

Amphibian Chytrid Fungus Infection Influences Calling Investment in Male Brown Toadlets

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
The sublethal effects of infection and disease on male advertisement behaviour remain poorly understood. Here we show that male brown toadlets infected with the amphibian chytrid fungus produce calls with more pulses compared to uninfected males. The association we report supports the terminal investment hypothesis and has the potential to impact host ...

Liquid‐Assisted Atmospheric Plasma Polymerization of Highly Viscous and Low‐Vapor Pressure Bio‐Based Monomer

open access: yesPlasma Processes and Polymers, Volume 22, Issue 8, August 2025.
Atmospheric plasma polymerization of highly viscous bio‐based isosorbide methacrylate is studied to enhance polymerization efficiency and film durability. The effects of discharge power, monomer injection rate, and plasma gas (argon vs. nitrogen) on the formation of stable coatings are investigated. Results demonstrate that argon plasma promotes higher

APPLICATION OF TRANSDUCTORS IN SHORT-CIRCUIT CURRENT MEASURING DEVICES

open access: yesAdvanced Engineering Research, 2012
The statement that transductors with magnetodielectric carbonyl iron dust-based magnetic circuits have the linear gain characteristic on the peak values throughout the full range of the real current value shift is proved in theory and by experiment ...

Testing non-standard neutrino matter interactions in atmospheric neutrino propagation

open access: yes, 2016
We study the effects of non-standard interactions on the oscillation pattern of atmospheric neutrinos. We use neutrino oscillograms as our main tool to infer the role of non-standard interactions (NSI) parameters at the probability level in the energy ...
