Assessment of the Kinetic Trajectory of the Median Nerve in the Wrist by High-Frequency Ultrasound

Sensors, 2014
Carpal tunnel syndrome (CTS) is typically diagnosed by physical examination or nerve conduction measurements. With these diagnostics however it is difficult to obtain anatomical information in the carpal tunnel.

Characterizing Cross-Country Consumption Correlations [PDF]

Review of Economics and Statistics, 1998
General equilibrium models of international fluctuations that assume complete asset markets predict that consumption will be highly correlated across countries, while the data display correlations that are rather low. It has become common to characterize this empirical regularity by noting that cross-country consumption correlations tend to be lower ...

Cosmology from cross correlation of CMB lensing and galaxy surveys

, 2013
In recent years cross correlation of lensing of the Cosmic Microwave Background (CMB) with other large scale structure (LSS) tracers has been used as a method to detect CMB lensing.

The Cross-Correlation between Galaxies and Groups: Probing the Galaxy Distribution in and around Dark Matter Haloes

, 2005
We determine the cross-correlation function between galaxies and galaxy groups, using both the Two-Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).

Correlation Flow: Robust Optical Flow Using Kernel Cross-Correlators

, 2018
Robust velocity and position estimation is crucial for autonomous robot navigation. The optical flow based methods for autonomous navigation have been receiving increasing attentions in tandem with the development of micro unmanned aerial vehicles.

Joint multifractal analysis based on the partition function approach: analytical analysis, numerical simulation and empirical application

New Journal of Physics, 2015
Many complex systems generate multifractal time series which are long-range cross-correlated. Numerous methods have been proposed to characterize the multifractal nature of these long-range cross correlations.

Photonic-Delay Line Cross Correlation Method Based on DWDM for Phase Noise Measurement

IEEE Photonics Journal, 2018
A dual photonic-delay line cross-correlation method for phase noise measurement of microwave signal based on dense wavelength division multiplexing (DWDM) is proposed and experimentally demonstrated. The kilometer-long delay fiber is used together by the

Noise Correlations in a Coulomb Blockaded Quantum Dot

, 2007
We report measurements of current noise auto- and cross-correlation in a tunable quantum dot with two or three leads. As the Coulomb blockade is lifted at finite source-drain bias, the auto-correlation evolves from super-Poissonian to sub-Poissonian in ...

Baryon acoustic oscillations with the cross-correlation of spectroscopic and photometric samples

, 2013
The baryon acoustic oscillation (BAO) experiment requires a sufficiently dense sampling of large-scale structure tracers with spectroscopic redshift, which is observationally expensive especially at high redshifts $z\simgt 1$.

Improved Cross-correlation for Template Matching on the Laplacian Pyramid [PDF]

, 1998
Template matching via cross-correlation on Laplacian pyramid image architectures has been traditionally performed in a "coarse" to "fine" fashion.
