Taiwan Oscillation Network [PDF]

open access: yes, 1995
The Taiwan Oscillation Network (TON) is a ground-based network to measure solar intensity oscillations to study the internal structure of the Sun. K-line full-disk images of 1000 pixels diameter are taken at a rate of one image per minute.

Duality Breaking of Vortex Configuration in a Hierarchical Honeycomb Network

open access: yes, 2009
We report measurements of Little-Parks oscillation on the hierarchical honeycomb-superconducting network for investigating possible effects of hierarchical structure in terms of spatial symmetry, parity and duality. We observed an asymmetric Little-Parks

5A2--Theory of the optical parametric oscillator [PDF]

open access: yes, 1966
A formalism for describing optical parametric oscillation is developed. The theory is applied to the derivation of the oscillation threshold condition, power output, the Manley-Rowe conditions, index matching, and frequency ...

An Unusual 500,000 Bases Long Oscillation of Guanine and Cytosine Content in Human Chromosome 21

open access: yes, 2004
An oscillation with a period of around 500 kb in guanine and cytosine content (GC%) is observed in the DNA sequence of human chromosome 21. This oscillation is localized in the rightmost one-eighth region of the chromosome, from 43.5 Mb to 46.5 Mb.

Effects of antibodies against dynein and tubulin on the stiffness of flagellar axonemes [PDF]

open access: yes, 1981
Antidynein antibodies, previously shown to inhibit flagellar oscillation and active sliding of axonemal microtubules, increase the bending resistance of axonemes measured under relaxing conditions, but not the bending resistance of axonemes measured ...

On the Asymptotic Behavior of a Class of Second-Order Non-Linear Neutral Differential Equations with Multiple Delays

open access: yesAxioms, 2020
In this work, we present some new sufficient conditions for the oscillation of a class of second-order neutral delay differential equation. Our oscillation results, complement, simplify and improve recent results on oscillation theory of this type of non-

Cilia oscillations

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2019
Cilia, or eukaryotic flagella, are microscopic active filaments expressed on the surface of many eukaryotic cells, from single-celled protozoa to mammalian epithelial surfaces. Cilia are characterized by a highly conserved and intricate internal structure in which molecular motors exert forces on microtubule doublets causing cilia oscillations.

Oscillation of Emden–Fowler-Type Neutral Delay Differential Equations

open access: yesAxioms, 2020
In this work, we consider a type of second-order functional differential equations and establish qualitative properties of their solutions. These new results complement and improve a number of results reported in the literature.

Asymptotic Properties of Neutral Differential Equations with Variable Coefficients

open access: yesAxioms, 2020
The aim of this work is to study oscillatory behavior of solutions for even-order neutral nonlinear differential equations. By using the Riccati substitution, a new oscillation conditions is obtained which insures that all solutions to the studied ...
