The role of identification in data‐driven policy iteration: A system theoretic study
International Journal of Robust and Nonlinear Control, EarlyView.Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

SPARLS: The Sparse RLS Algorithm
IEEE Transactions on Signal Processing, 2010 We develop a recursive L1-regularized least squares (SPARLS) algorithm for the estimation of a sparse tap-weight vector in the adaptive filtering setting.

Dynamic Modelling of Critical Infrastructures for Improved Disaster Habitation Recovery
Systems Research and Behavioral Science, EarlyView.ABSTRACT Natural disasters damage infrastructure systems that support housing habitability, leading to population displacement. Recovery efforts speed up infrastructure capacity restoration and, thereby, rehabitation by displaced residents. Current recovery policy analysis methods focus on individual infrastructure systems or overall community recovery

Hydrogen Generation Catalyzed by Fluorinated Diglyoxime−Iron Complexes at Low Overpotentials [PDF]
, 2012 Fe^(II) complexes containing the fluorinated ligand 1,2-bis(perfluorophenyl)ethane-1,2-dionedioxime (dAr^FgH_2; H = dissociable proton) exhibit relatively positive Fe^(II/I) reduction potentials.

SusMat, EarlyView.The study uses rapidly prepared Cr NPs with controllable fluorescence, enabling co‐regulation of quenching and enhancement for dyes and DNA of differing structures. By assembling a CD63‐specific aptamer with Cr NPs, it creates a quantitative readout for CD63‐positive TDEs.

Restless legs syndrome in end stage renal disease patients undergoing hemodialysis
BMC Neurology, 2019 Background The prevalence of Restless legs syndrome (RLS) in End Stage Renal Disease (ESRD) patients is higher than that in the general population. However, the associations of RLS within the ESRD population are inconsistent and RLS is usually neglected ...

Imposing Observation-Varying Equality Constraints Using Generalised Restricted Least Squares [PDF]
Linear equality restrictions derived from economic theory are frequently observation-varying. Except in special cases, Restricted Least Squares (RLS) cannot be used to impose such restrictions without either underconstraining or overconstraining the ...

Veterinary Record, EarlyView.Abstract Background Managing open wounds in birds is challenging. This study compared leukocyte‐ and thrombocyte‐rich fibrin (L‐TRF) and autologous grafts for treating wounds in the tarsometatarsus of chickens. Methods Full‐thickness wounds were experimentally induced in the tarsometatarsus of 23 healthy adult chickens.

A New Approach to Adaptive Signal Processing
, 2015 A unified linear algebraic approach to adaptive signal processing (ASP) is presented. Starting from just Ax=b, key ASP algorithms are derived in a simple, systematic, and integrated manner without requiring any background knowledge to the field ...

Managing the Threat of Subsidized Predators for a Threatened Shorebird
Animal Conservation, EarlyView.Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...
