Effects of CO2 their modulation light in the life-cycle stages the coccolithophoreEmiliania huxleyi
2014/4/2
The effects of ocean acidification on the life-cycle stages of the coccolithophoreEmiliania huxleyiand their modulation by light were examined. Calcifying diploid and noncalcifying haploid cells (Rosc...
Robust laser frequency stabilization by serrodyne modulation
Robust laser frequency stabilization serrodyne modulation
2012/2/28
We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic ...
No role for muons in the DAMA annual modulation results
No role muons DAMA annual modulation results
2012/2/23
Since long time it has been pointed out by the DAMA collaboration that muons surviving the Gran Sasso mountain cannot mimic the Dark Matter annual modulation signature exploited by the DAMA/NaI and DA...
Efficient and flexible generation of entangled qudits with cross-phase modulation
Efficient flexible generation entangled qudits cross-phase modulation
2013/7/3
In this paper, we provide a simple but powerful module to generate entangled qudits. This module, assisted with cross-Kerr nonlinearity, is flexible for generation of entangled qudits with arbitrary d...
A Novel Direct Detection Microwave Photonic Vector Modulation Scheme for Radio-Over-Fiber System
2011/11/22
This letter demonstrates the feasibility of a novel direct detection microwave photonic vector modulation scheme for the radio-over-fiber (RoF) system. Unlike the traditional double-sideband with opti...
Modulation and natural valued quiver of an algebra
Modulation natural valued quive algebra
2018/4/19
The concept of modulation is generalized to pseudo-modulation and its subclassesincluding pre-modulation, generalized modulation and regular modulation. The moti-
vation is to deˉne the valued analog...
Curvature perturbation from velocity modulation
Curvature perturbation velocity modulation
2011/10/9
We propose a new variant model of the modulated reheating. If particles have large scale fluctuations on their velocities, or equivalently their Lorentz factors, the decay rate also fluctuates and the...
We analyze the recently released CoGeNT data with a focus on their time-dependent properties. Using various statistical techniques, we confirm the presence of modulation in the data, and find a signif...

Nonlinear Bose-Einstein-condensate Dynamics Induced Harmonic Modulation the s-wave Scattering Length
2011/9/15
In a recent experiment, a Bose-Einstein condensate of 7Li has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an analytical perturbati...
Time-Frequency Analysis of Superorbital Modulation of X-ray Binary SMC X-1 by Hilbert-Huang Transform
