Chromaticity of Gravitational Microlensing Events [PDF]

, 1999
In this paper, we investigate the color changes of gravitational microlensing events caused by the two different mechanisms of differential amplification for a limb-darkened extended source and blending.

Correction Factors for Reactions involving Quark-Antiquark Annihilation or Production

, 1994
In reactions with $q \bar q$ production or $q\bar q$ annihilation, initial- and final-state interactions give rise to large corrections to the lowest-order cross sections.

Fault-tolerant error correction with the gauge color code [PDF]

, 2016
The constituent parts of a quantum computer are inherently vulnerable to errors. To this end we have developed quantum error-correcting codes to protect quantum information from noise.

A Fast Sand-Dust Image Enhancement Algorithm by Blue Channel Compensation and Guided Image Filtering

IEEE Access, 2020
The images captured in sand-dust weather have the characteristics of color deviation and low visibility, which seriously affect computer vision systems. To solve the above problems, we propose a fast and effective algorithm to enhance the images captured

Disk Dominated States of 4U 1957+11: Chandra, XMM, and RXTE Observations of Ostensibly the Most Rapidly Spinning Galactic Black Hole

, 2008
We present simultaneous Chandra-HETG and RXTE observations of a moderate flux `soft state' of the black hole candidate 4U1957+11. These spectra, having a minimally discernible hard X-ray excess, are an excellent test of modern disk atmosphere models that

Underwater Image Enhancement via Adaptive Color Correction and Stationary Wavelet Detail Enhancement

IEEE Access
High-quality images are of great significance for vision tasks in underwater environments. However, as light propagates through water, it is scattered and absorbed, which commonly causes issues like color distortion and loss of detail, making the capture
