Interpolation methods frequently deal poorly with noise. Least-squares based interpolation methods can deal well with noise, as long as it is Gaussian and zero-mean. When this is not the case, other methods are needed. I use an iteratively-reweighted least-squares scheme to interpolate both regular and sparse data with non-stationary prediction-error filters. I show that multi-scale methods are...

bacteriorhodopsin operates as a light/proton transfer pump which converts the light energy into a proton gradient. energy stored in the proton gradient can be used in a variety of ways. bacteriorhodopsin producing sources are some halobacterium species such as halobacterium sodomense and halobacterium salinarum which continue to grow in harsh and salt-saturated conditions. two types of red pigm...

Abstract Structural Health Monitoring (SHM) is an important tool to maintain structures integrity and safety. Gapped Smoothing Method (GSM) a high sensitivity algorithm for damage detection using mode shape curvature (MSC) identify small size of damage. However, it has limited capability localize wide with decent accuracy. The objective this study improve GSM Robust Regression i.e., Iteratively...

In this paper, we propose a novel algorithm for analysis-based sparsity reconstruction. It can solve the generalized problem by structured sparsity regularization with an orthogonal basis and total variation regularization. The proposed algorithm is based on the iterative reweighted least squares (IRLS) model, which is further accelerated by the preconditioned conjugate gradient method. The con...

PURPOSE To profile macular thickness changes in glaucoma by using three-dimensional spectral-domain optical coherence tomography (3D-SD-OCT). METHODS The study included 30 eyes with suspected glaucoma and preperimetric glaucoma (SGPPG) and 35 healthy eyes. The macular thickness, including those of the total retina, nerve fiber layer (NFL), and combined inner retinal layers (IRLs)-NFL+ganglion...

BACKGROUND AND PURPOSE Enhanced external counter pulsation (EECP) is used to treat angina. With sustained treatment this increases collateral circulation to the coronary arteries as well as to the body as a whole. We found some patients who underwent EECP for angina or congestive heart failure who also coincidentally had severe Restless Legs Syndrome (RLS). Case reports are presented. PATIENT...

BACKGROUND AND OBJECTIVES Restless legs syndrome (RLS) and sleep disturbances are common among in-center hemodialysis patients and are associated with increased morbidity/mortality. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The FREEDOM study is an ongoing prospective cohort study investigating the benefits of home short daily hemodialysis (SDHD) (6 times/week). In this interim report, we ...

Iteratively Re-weighted Least Squares (IRLS) is a method for solving minimization problems involving non-quadratic cost functions, perhaps non-convex and non-smooth, which however can be described as the infimum over a family of quadratic functions. This transformation suggests an algorithmic scheme that solves a sequence of quadratic problems to be tackled efficiently by tools of numerical lin...

OBJECTIVE To assess the efficacy, safety, and tolerability of ropinirole in the treatment of patients with restless legs syndrome. METHODS A 12 week, prospective, double blind, randomised comparison involving 284 patients from 10 European countries. All participants had a score of > or =15 on the international restless legs scale (IRLS). Patients were randomised (1:1) to receive either ropini...
