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

Direction-of-Arrival Estimation Based on Joint Sparsity
Sensors, 2011 We present a DOA estimation algorithm, called Joint-Sparse DOA to address the problem of Direction-of-Arrival (DOA) estimation using sensor arrays. Firstly, DOA estimation is cast as the joint-sparse recovery problem.
