Test of Bell's Inequality using the Spin Filter Effect in Ferromagnetic Semiconductor Micro-structures

open access: yes, 2000
A theoretical proposal for testing Bell's inequality in mesoscopic systems is presented. We show that the entanglement of two electron spins can be detected in the spin filter effect in the mesoscopic semiconductor / ferromagnetic semiconductor ...

The FFX Correlator

open access: yes, 2008
We established a new algorithm for correlation process in radio astronomy. This scheme consists of the 1st-stage Fourier Transform as a filter and the 2nd-stage Fourier Transform for spectroscopy.

Feature subset selection: a correlation based filter approach [PDF]

open access: yes, 1997
Recent work has shown that feature subset selection can have a position affect on the performance of machine learning algorithms. Some algorithms can be slowed or their performance adversely affected by too much data some of which may be irrelevant or ...

Dipolar Filtered magic-sandwich-echoes as a tool for probing molecular motions using time domain NMR

open access: yes, 2017
We present a simple $^1$H NMR approach for characterizing intermediate to fast regime molecular motions using $^1$H time-domain NMR at low magnetic field. The method is based on a Goldmann Shen dipolar filter (DF) followed by a Mixed Magic Sandwich Echo (

A Novel Incremental Multi-Template Update Strategy for Robust Object Tracking

open access: yesIEEE Access, 2020
In the field of correlation filter object tracking, the traditional template-update method easily causes template drift, so it performs poorly in complex scenes.
