Kink Oscillations of Coronal Loops [PDF]
Space Science Reviews, 2021 Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy releases, such as low coronal eruptions. Typical periods of the oscillations

Collective Coordinate Model of Kink-Antikink Collisions in ϕ^{4} Theory. [PDF]
Physical Review Letters, 2021 The fractal velocity pattern in symmetric kink-antikink collisions in ϕ^{4} theory is shown to emerge from a dynamical model with two effective moduli: the kink-antikink separation and the internal shape mode amplitude.

Kink dynamics of the sine-Gordon equation in a model with three identical attracting or repulsive impurities [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2023 Purpose of this work is to use analytical and numerical methods to consider the problem of the structure and dynamics of the kinks in the sine-Gordon model with “impurities” (or spatial inhomogeneity of the periodic potential).

Excitement of solitons in the interaction of kinks of sine-Gordon equation with attracting impurity [PDF]
Компьютерные исследования и моделирование, 2012 We investigate analytically and numerically the structure and properties of localized two- and three-kink solutions of the sine-Gordon equation, which are excited in the region of the attracting impurity.

Extensive investigation of the ultrastructure of kink-bands in flax fibres
Industrial crops and products (Print), 2021 Fibres from annual plants are a sustainable alternative to glass fibres in composite manufacturing. However, both synthetic fibres, such as carbon fibres, and cellulosic fibres exhibit heterogeneities along their lengths, which appear as localised ...

Domain Structure Formation in Designing of the Opened Informative Measuring Systems
Приборы и методы измерений, 2022 The opened systems possess an increasing significance and possibilities of applying in designing of measuring devices. Now an essentially nonlinear models are used for such systems. The perturbation approach is not enough for these purposes.
