Spin cross-correlation experiments in an electron entangler. [PDF]
Correlations are fundamental in describing many-body systems. However, in experiments, correlations are notoriously difficult to assess on a microscopic scale, especially for electron spins.

A Novel Cross-Correlation Algorithm Based on the Differential for Target Detection of Passive Radar
For the problem of traditional passive radar target detection, the cross-correlation method is a popular solution. By processing the reference signal and the target echo signal coherently, the method is able to extract the target parameters, such as ...

An optimization method of observation matrix based on QR decomposition
In compressed sensing theory, the most critical issue is the construction of the observation matrix. The factors that affect the image reconstruction quality include the independence between the observation matrix column vectors and the cross-correlation

Baryon acoustic oscillations from the cross-correlation of Lyα absorption and quasars in eBOSS DR14 [PDF]
We present a measurement of the baryon acoustic oscillation (BAO) scale at redshift z = 2.35 from the three-dimensional correlation of Lyman-α (Lyα) forest absorption and quasars. The study uses 266 590 quasars in the redshift range 1.77 < z < 3.5 from

CMB lensing reconstruction biases in cross-correlation with large-scale structure probes [PDF]
The cross-correlation between cosmic microwave background (CMB) gravitational lensing and large-scale structure tracers will be an important cosmological probe in the coming years. Quadratic estimators provide a simple and powerful (if suboptimal) way to
