A variation in right atrial and pulmonary arterial pressure might result in a shunt dynamic across a patent foramen ovale (PFO). In the present study we tested if peak exercise facilitates a restoration of right to left shunt (RLS) in stroke patients who demonstrated a functional PFO closure (no evidence of RLS across an initially demonstrated PFO). In stroke patients with PFO demonstrating a f...

This thesis introduces analysis tools for improving the current state of the art of heuristics for the Maximum Clique (MC) problem. The analysis focusses on algorithmic building blocks, on their contribution in solving hard instances of the MC problem, and on the development of new tools for the visualisation of search landscapes. As a result of the analysis on the algorithmic building blocks, ...

restless leg syndrome (rls) is a common cause of painful legs. the leg pain of restless leg syndrome typically eases with motion of the legs and becomes more noticeable at rest. stress or emotional upset can make symptoms worse. the purpose of the present study was to examine the relationship of emotional disturbance and quality of life to the severity of rls. using a descriptive-correlational ...

conclusions pregnancies complicated by rls are at increased risk for preterm birth. the improved sleep health of pregnant women could decrease pregnancy complications. results rls complicated 43.7 percent of pregnancies. sleepiness (ess score > 8) was reported in 36.4% of the subjects with preterm birth and 35.9% of the term group. no significant correlation was found between the ess score and ...

The symptoms of restless legs syndrome (RLS) are associated with reductions in patients' quality of life (QoL) and mental heath. Sleep disturbance, which is often the most troublesome symptom of RLS, may have a negative impact on patients' daytime cognitive abilities. Research has established a relationship between the symptoms of RLS and mood symptoms, but causality is unclear. Some studies ha...

BACKGROUND Restless legs syndrome (RLS), a common sensorimotor disorder, has a wide range of severity from merely annoying to affecting sleep and quality of life severely enough to warrant medical treatment. Previous epidemiological studies, however, have failed to determine the prevalence of those with clinically significant RLS symptoms and to examine the life effects and medical experiences ...

UNLABELLED RLSOBJECTIVES: To evaluate the humanistic and economic burden of a restless legs syndrome (RLS) diagnosis with regard to health-related quality of life, work productivity loss, healthcare resource use, and direct and indirect costs. STUDY DESIGN Self-reported data came from the 2012 National Health and Wellness Survey (NHWS), a large, annual, nationally representative cross-section...

This paper is concerned with studying the forgetting factor of the recursive least square (RLS). A new dynamic forgetting factor (DFF) for RLS algorithm is presented. The proposed DFF-RLS is compared to other methods. Better performance at convergence and tracking of noisy chirp sinusoid is achieved. The control of the forgetting factor at DFF-RLS is based on the gradient of inverse correlation...

Our research is to develop the low-complexity broadband microphone beamformer which has robustness to moving interference signal. In this paper, an improved broadband GSC-RLS beamformer structure with fast self-tuning algorithm is proposed. Also, the improved fast self-tuning algorithm for the proposed GSC-RLS structure is developed, based on the Song‟s method. The computational complexity of t...

Recently, recursive least square (RLS), or extended Kalman ltering (EKF), based algorithms have been demonstrated to be a class of eeective online training methods for neural networks. This paper discusses several aspects of pruning a neural network trained by the RLS based approach. Based on our study, the RLS approach is implicitly a weight decay training algorithm. Also, we derive two prunin...
