Political Partisanship and State‐Level Bank Efficiency
Financial Review, EarlyView.ABSTRACT We examine the relationship between political partisanship and commercial bank efficiency in the United States from 1972 to 2020, assessing the persistent influence of political affiliations at the state and District of Columbia levels. Bank efficiency scores are estimated using a double‐bootstrap approach, and the analysis is conducted within

Performance Improvement for Wideband DOA estimation with White Noise Reduction Based on Uniform Linear Arrays [PDF]
, 2016 A method is proposed for reducing the effect of white noise in wide- band uniform linear arrays via a combination of a judiciously de- signed transformation followed by highpass filters. The reduced noise level leads to a higher signal to noise ratio for

Performance evaluation of direction-of-arrival (DOA) estimation algorithms for mobile communication systems [PDF]
VTC2000-Spring. 2000 IEEE 51st Vehicular Technology Conference Proceedings (Cat. No.00CH37026), 2002 Spatial filtering for mobile communications has attracted a lot of attention over the last decade and is currently considered a very promising technique that will help future cellular networks achieve their ambitious goals. One way to accomplish this is via array signal processing with algorithms which estimate the direction-of-arrival (DOA) of the ...
