Circadian Oscillation of the Lettuce Transcriptome under Constant Light and Light–Dark Conditions

open access: yesFrontiers in Plant Science, 2016
Although, the circadian clock is a universal biological system in plants and it orchestrates important role of plant production such as photosynthesis, floral induction and growth, there are few such studies on cultivated species.

A critical oscillation constant as a variable of time scales for half-linear dynamic equations

open access: yes, 2010
We present criteria of Hille-Nehari type for the half-linear dynamic equation (r(t)Φ(yΔ))Δ+p(t)Φ(yσ) = 0 on time scales. As a particular important case we get that there is a a (sharp) critical constant which may be different from what is known from the ...

Cooling and self-oscillation in a nanotube electromechanical resonator [PDF]

open access: yesNature Physics, 2019
Nanomechanical resonators are used with great success to couple mechanical motion to other degrees of freedom, such as photons, spins and electrons1,2. The motion of a mechanical eigenmode can be efficiently cooled into the quantum regime using photons2 ...

The Oscillation of a Class of the Fractional-Order Delay Differential Equations

open access: yesDiscrete Dynamics in Nature and Society, 2014
Several oscillation results are proposed including necessary and sufficient conditions for the oscillation of fractional-order delay differential equations with constant coefficients, the sufficient or necessary and sufficient conditions for the ...

Bloch Oscillations Due to Quantum Domain Breathing in One-Dimensional Electronic Photoinduced Phase Transitions

open access: yesApplied Sciences, 2019
We theoretically predict a novel oscillation that will be observed during the dynamical processes of one-dimensional electronic photoinduced phase transitions.

Numerical Analysis of Aeroacoustic Characteristics around a Cylinder under Constant Amplitude Oscillation

open access: yesEnergies, 2022
The present study numerically investigated a cylinder under oscillating motions at a low Reynolds number. The effects of two oscillation frequencies and amplitudes on the lift drag coefficient, near-field surface pressure fluctuation, and far-field noise

Relation between dispersion lines and conductance of telescoped armchair double-wall nanotubes analyzed using perturbation formulas and first-principles calculations

open access: yes, 2012
The Landauer's formula conductance of the telescoped armchair nanotubes is calculated with the Hamiltonian defined by first-principles calculations (SIESTA code). Herein, partially extracting the inner tube from the outer tube is called 'telescoping'. It

Prospects for Resolving the Hubble Constant Tension with Standard Sirens. [PDF]

open access: yesPhysical Review Letters, 2018
The Hubble constant (H_{0}) estimated from the local Cepheid-supernova distance ladder is in 3-σ tension with the value extrapolated from cosmic microwave background (CMB) data assuming the standard cosmological model. Whether this tension represents new

A Survey on the Oscillation of Difference Equations with Constant Delays

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2019
In this survey, necessary and sufficient conditions for the oscillation of all solutions of delay difference equations with one or several constant arguments, in terms of the characteristic equation, are presented.
