The recursive least-squares (RLS) algorithm is one of the most well-known algorithms used in adaptive filtering, system identification and adaptive control. Its popularity is mainly due to its fast convergence speed, which is considered to be optimal in practice. In this paper, RLS methods are used to solve reinforcement learning problems, where two new reinforcement learning algorithms using l...

The aim of this study was to assess the prevalence of idiopathic restless legs syndrome (RLS) and its correlations in a sample of Medical School faculty members. A transversal study was conducted at a Medical School in the south of Brazil included 78 faculty members. The subjects answered to a structured questionnaire specific to RLS diagnosis and the Epworth and the Stanford scales to measure ...

Restless Legs Syndrome (RLS) is a common movement disorder characterized by a circadian variation in symptoms involving an urge to move the limbs, usually the legs. Pregnant women, patients with end-stage renal disease or iron-deficiency anemia, and children with attention deficit hyperactivity disorder (AD/HD) have a significantly higher prevalence of RLS. The classic presentation includes the...

Restless Legs Syndrome (RLS) is a common condition associated with many medical illnesses and medications. Psychotropic medications (both antidepressants and antipsychotics) may be causal. There have been over twenty cases of RLS due to Quetiapine but no published case reports linking RLS to Quetiapine XR. We present the case of a woman with previously established Bipolar Disorder who presented...

OBJECTIVES To characterize and describe the prevalence of restless leg syndrome (RLS) in hospitalized psychiatric patients and to investigate the correlations between patient profile and RLS. METHODS Demographic information, psychiatric diagnoses, psychotropic medication use, and history of substance use were collected from hospitalized psychiatric patients at the American University of Beiru...

BACKGROUND AND PURPOSE A high prevalence of right-to-left shunt (RLS) was described in a family of patients with CADASIL, a rare cerebral arteriopathy attributable to Notch3 gene mutations. The aim of this study was to determine the prevalence of RLS in patients with CADASIL and possible relation to clinical phenotype and cerebral MRI lesion load. METHODS Twenty-three CADASIL patients underwe...
