MODULATIONAL INSTABILITY OF THE RADIAL VIBRATIONS OF CORONAL LOOPS
Современная наука и инновации, 2022 Axisymmetric modes in coronal loops are used to interpret observed fast microwave and hard x-ray pulsations. Their properties are well studied in the approximation of linear magnetic hydrodynamics.

Vibrations of straight pipes/beams with two-sided stops: Analytical and numerical analyzes
Forces in Mechanics, 2021 The impacts on pipes or beams are of fundamental mechanical interest. These impacts can be studied analytically. This makes it easier to examine the basic effects and to compare these effects with the results of finite element analyzes (FEA).

Lyapunov Mode Dynamics in Hard-Disk Systems [PDF]
Journal of Statistical Physics, 2008 The tangent dynamics of the Lyapunov modes and their dynamics as generated numerically - {\it the numerical dynamics} - is considered. We present a new phenomenological description of the numerical dynamical structure that accurately reproduces the experimental data for the quasi-one-dimensional hard-disk system, and shows that the Lyapunov mode ...

Reaching Hard-to-Survey Populations: Mode Choice and Mode Preference [PDF]
Journal of Official Statistics, 2014 This study assesses the effect of response-mode choices on response rates, and responsemode preferences of hard-to-survey populations: young adults, full-time workers, big city inhabitants, and non-Western immigrants. Using address-based sampling, a stratified sample of 3,496 households was selected. The first group of sample members was contacted face

From Lyapunov modes to their exponents for hard disk systems [PDF]
Physical Review E, 2010 We demonstrate the preservation of the Lyapunov modes by the underlying tangent space dynamics of hard disks. This result is exact for the zero modes and correct to order $ε$ for the transverse and LP modes where $ε$ is linear in the mode number. For sufficiently large mode numbers the dynamics no longer preserves the mode structure.

Mode transformer for hard-surface waveguides [PDF]
31st European Microwave Conference, 2001, 2001 Mode transformation effect inside a corrugated circular waveguide filled with gyrotropic material, e.g., magnetoplasma or ferrite, is considered. The corrugation is in axial direction and the depth of the corrugation is a quarter wave length forming a boundary condition equal to a hard surface (HS).
