Using forensics to inspire the next generation of regolith, soil and clay scientists
Using forensics inspire next generation regolith soil clay scientists
font style='font-size:12px;'>
2012/3/30
These days we need to work harder to attract students to study regolith, soil and clay science because they have a somewhat dry and dusty image or muddy and smelly, but this stereotype can be far from...
Generation of continuous-variable quadripartite square cluster state and its entanglement improvement via quantum feedback
quantum optics continuous variable cluster state feedback
font style='font-size:12px;'>
2011/12/15
In this paper, we investigate the generation of continuous-variable quadripartite square cluster state of optical fields and discuss the enhancement of the multipartite entanglement of the cluster sta...
Optical Millimeter-Wave Signal Generation Using Frequency Quadrupling Technique and No Optical Filtering
font style='font-size:12px;'>
2011/11/22
This letter demonstrates a novel method to generate high-purity optical millimeter-wave signals with carrier suppression by using a frequency quadrupling technique. To the authors’ knowledge, this is ...
Tracing the structure of asymmetric molecules from high-order harmonic generation
Tracing the structure asymmetric molecules high-order harmonic generation
font style='font-size:12px;'>
2014/5/28
We investigate high-order harmonic generation (HHG) from asymmetric molecules exposed to intense laser fields. We show that the emissions of odd and even harmonics depend differently on the orientatio...
Second-generation microlensing planet surveys: a realistic simulation
surveys – gravitational lensing: micro – methods: statistical – binaries: general – planetary systems – Galaxy: stellar content
font style='font-size:12px;'>
2011/10/20
Microlensing surveys, which have discovered about a dozen extrasolar planets to date, have focused on the small minority of high-magnification lensing events, which have a high sensitivity to planet d...

2011/10/18
We present the first self-consistent three-dimensional particle-in-cell simulations of the Kelvin-Helmholtz instability (KHI) in an unmagnetized scenario. We discuss the main features, including densi...
