Non-LTE ionization potential depression model for warm and hot dense plasma
Chensheng Wu, Fuyang Zhou, Yong Wu +3
For warm and hot dense plasma (WHDP), the ionization potential depression (IPD) is a key physical parameter in determining its ionization balance, therefore a reliable and universa…
Extending Science from Lunar Laser Ranging
Vishnu Viswanathan, Erwan Mazarico, Stephen Merkowitz +18
The Lunar Laser Ranging (LLR) experiment has accumulated 50 years of range data of improving accuracy from ground stations to the laser retroreflector arrays (LRAs) on the lunar su…
Randomized Spectral Sampling for Efficient Simulation of Laser Propagation through Optical Turbulence
Daniel A. Paulson, Chensheng Wu, Christopher C. Davis
We present a new method for the generation of atmospheric turbulence phase screens based on the frequency shift property of the Fourier transform. This method produces low spatial…
Variation of the transition energies and oscillator strengths for the 3C and 3D lines of the Ne-like ions under plasma environment
Chensheng Wu, Shaomin Chen, T. N. Chang +1
We present the results of a detailed theoretical study which meets the spatial and temporal criteria of the Debye-Huckel (DH) approximation on the variation of the transition energ…
Object Detection and Geometric Profiling through Dirty Water Media Using Asymmetry Properties of Backscattered Signals
Chensheng Wu, Robert Lee, Christopher C. Davis
The scattering of light observed through the turbid underwater channel is often regarded as the leading challenge when designing underwater electro-optical imaging systems. There h…
Allometric Scaling in Scientific Fields
Hongguang Dong, Menghui Li, Ru Liu +2
Allometric scaling can reflect underlying mechanisms, dynamics and structures in complex systems; examples include typical scaling laws in biology, ecology and urban development. I…
Do Mathematicians, Economists and Biomedical Scientists Trace Large Topics More Strongly Than Physicists?
Menghui Li, Liying Yang, Huina ZHang +3
In this work, we extend our previous work on largeness tracing among physicists to other fields, namely mathematics, economics and biomedical science. Overall, the results confirm…
Using an incoherent target-return to adaptively focus through atmospheric turbulence
William Nelson, John P. Palastro, Chensheng Wu +1
A laser beam propagating to a remote target through atmospheric turbulence acquires intensity fluctuations. If the target is cooperative and provides a coherent return beam, the ph…
Using Graph Theory and a Plenoptic Sensor to Recognize Phase Distortions of a Laser Beam
Chensheng Wu, Jonathan Ko, Christopher C. Davis
Atmospheric turbulence causes fluctuations in the local refractive index of air that accumulatively disturb a wave's phase and amplitude distribution as it propagates. This impairs…
Interrelations among scientific fields and their relative influence revealed by input-output analysis
Zhesi Shen, Liying Yang, Jiansuo Pei +7
In this paper, we try to answer two questions about any given scientific discipline: First, how important is each subfield and second, how does a specific subfield influence other…
Determining the Phase and Amplitude Distortion of a Wavefront using a Plenoptic Sensor
Chensheng Wu, Jonathan Ko, Christopher C. Davis
We have designed a plenoptic sensor to retrieve phase and amplitude changes resulting from a laser beam's propagation through atmospheric turbulence. Compared with the commonly res…
Enhanced backscatter of optical beams reflected in turbulent air
W. Nelson, J. P. Palastro, C. Wu +1
Optical beams propagating through air acquire phase distortions from turbulent fluctuations in the refractive index. While these distortions are usually deleterious to propagation,…
From sparse to dense and from assortative to disassortative in online social networks
Menghui Li, Shuguang Guan, Chensheng Wu +5
Inspired by the analysis of several empirical online social networks, we propose a simple reaction-diffusion-like coevolving model, in which individuals are activated to create lin…
Do scientists trace hot topics?
Tian Wei, Menghui Li, Chensheng Wu +4
Do scientists follow hot topics in their scientific investigations? In this paper, by performing analysis to papers published in the American Physical Society (APS) Physical Review…
