Blind Adaptive Interference Suppression Based on Set-Membership Constrained Constant-Modulus Algorithms with Time-Varying Bounds

Rodrigo C. de Lamare, Paulo S. R. Diniz

This work presents blind constrained constant modulus (CCM) adaptive algorithms based on the set-membership filtering (SMF) concept and incorporates dynamic bounds {for interferenc…

First observation of the decays $B ˉ_{(s)}^{0} \to D_{s}^{+} K^{-} π^{+} π^{-}$ and $B ˉ_{s}^{0} \to D_{s 1} (2536)^{+} π^{-}$

LHCb collaboration, R. Aaij, C. Abellan Beteta +621

The first observation of the decays $B ˉ_{s}^{0} \to D_{s}^{+} K^{-} π^{+} π^{-}$ and $B ˉ^{0} \to D_{s}^{+} K^{-} π^{+} π^{-}$ are reported using an integrated luminosity of 1.0 fb $^{- 1}$ recorded by the…

Anomalous metamagnetic-like transition in a FeRh/Fe $_{3}$ Pt interface occurring at T120 K in the field-cooled-cooling curves for low magnetic fields

S. Salem-Sugui, A. D. Alvarenga, R. D. Noce +4

We report on the magnetic properties of a special configuration of a FeRh thin film. An anomalous behavior on the magnetisation vs. temperature was observed when low magnetic field…
