The Lower Limit of Pitch Perception for Pure Tones and Low-Frequency Complex Sounds
Archives of Acoustics, 2021 The lower limit of pitch (LLP) perception was explored for pure tones, sinusoidally amplitude-modulated (SAM) tones with a carrier frequency of 125 Hz, and trains of 125-Hz tone pips, using an adaptive procedure to estimate the lowest repetition rate for

On Weak Solvability of Boundary Value Problem with Variable Exponent Arising in Nanostructure
Journal of Function Spaces, 2021 This work is devoted to study the limit behavior of weak solutions of an elliptic problem with variable exponent, in a containing structure, of an oscillating nanolayer of thickness and periodicity parameter depending on ε.

Dynamics and Collapse in a Power System Model with Voltage Variation: The Damping Effect. [PDF]
PLoS ONE, 2016 Complex nonlinear phenomena are investigated in a basic power system model of the single-machine-infinite-bus (SMIB) with a synchronous generator modeled by a classical third-order differential equation including both angle dynamics and voltage dynamics,

Fractional magnetoresistance oscillations in spin-triplet superconducting rings
Communications Physics, 2023 Half-quantum vortices in spin-triplet superconductors are predicted to host Majorana zero modes and may provide a viable platform for topological quantum computation. Recent works also suggested that, in thin mesoscopic rings, the superconducting pairing

Emergent periodicity in the collective synchronous flashing of fireflies
eLife, 2023 In isolation from their peers, Photinus carolinus fireflies flash with no intrinsic period between successive bursts. Yet, when congregating into large mating swarms, these fireflies transition into predictability, synchronizing with their neighbors with

Asymptotically almost periodic solutions of limit and almost periodic linear difference systems
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper, limit periodic and almost periodic homogeneous linear difference systems are considered. We study the systems in which the coefficient matrices are taken from a given bounded group and the elements of the matrices are from an infinite ...

On Periodicity in Limit Sets [PDF]
Proceedings of the American Mathematical Society, 1967 The purpose of this paper is to give a necessary and sufficient condition in order that the S limit set of a point consists of exactly one periodic orbit which is both S-Lyapunov stable and S-asymptotically stable. The general reference for most terms used in this paper is [2]. In this paper we assume (X, T, r) is a transformation group.
