Improving Performance of Affine Projection–Like Algorithm Using Two Combination Methods
Journal of Applied MathematicsThe affine projection–like (APL) algorithm has garnered significant attention due to its low steady-state mean-square deviation and simplicity. However, its performance is limited by a fixed step-size, which forces a trade-off between fast convergence ...

Sparse Adaptive Channel Estimation Based on lp-Norm-Penalized Affine Projection Algorithm
International Journal of Antennas and Propagation, 2014 We propose an lp-norm-penalized affine projection algorithm (LP-APA) for broadband multipath adaptive channel estimations. The proposed LP-APA is realized by incorporating an lp-norm into the cost function of the conventional affine projection algorithm (

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Low Cost Variable Step-Size LMS With Maximum Similarity to the Affine Projection Algorithm
IEEE Open Journal of Signal ProcessingThe LMS algorithm is widely employed in adaptive systems due to its robustness, simplicity, and reasonable performance. However, it is well known that this algorithm suffers from a slow convergence speed when dealing with colored reference signals ...

On breathers in affine toda theories [PDF]
, 1995 Oscillating solitonic solutions, the breathers, of affine Toda theory are studied. These breather solutions are constructed from two solitons of the same mass with velocity opposite of each other; by analytically continuing its velocity or rapidity to a ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Fast exact variable order affine projection algorithm [PDF]
, 2012 Variable order affine projection algorithms have been recently presented to be used when not only the convergence speed of the algorithm has to be adjusted but also its computational cost and its final residual error. These kind of affine projection (AP)
