Chronic low back pain (CLBP) is one of the most common, poorly understood, and potentially disabling chronic pain conditions from which older adults suffer. Many older adults remain quite functional despite CLBP, and because age-related comorbidities often exist independently of pain (e.g., medical illnesses, sleep disturbance, mobility difficulty), the unique impact of CLBP is unknown. We cond...

Microgrids (MGs) contain a diverse mix of energy resources to provide safe and secure power to the consumers. Batteries are utilized in MGs for further energy security assurance as well as cost minimization. In this paper, an efficient approach is introduced for simultaneous energy management and optimal battery sizing to accomplish economic MG operation. Also, demand response programs are empl...

12 Bioelectrical surface recordings are usually performed by unipolar or bipolar disc electrodes even 13 though they entail the serious disadvantage of having poor spatial resolution. Concentric ring electrodes 14 give improved spatial resolution, although this type of electrode has so far only been implemented in 15 rigid substrates and as they are not adapted to the curvature of the recording...

OBJECTIVE The present study investigated whether teacher ratings and parent ratings of inattentive or hyperactive/impulsive symptoms were differently associated with intelligence or cognitive performance in Korean children. METHODS Six hundred sixty-seven children were recruited from nine schools in five Korean cities. The teachers and parents of 580 of these children (9.0±0.7 years old, 333 ...

Materials for use in auditory perceptual assessment of central auditory problems are widely divergent in quality, usefulness, and complexity. These circumstances make interpreting results a highly provincial affair. Comparison of results between different clinics and laboratories is often difficult or impossible. Norms by which to judge an individual's performance are often applicable for only ...

This publication deals with the spatially resolved simulation of a sodium–iodine secondary battery. The anode compartment consists molten sodium and cathode contains high-conductivity metal disc as electrode an aqueous catholyte. latter comprises iodide, triiodide, dissolved iodine, ions. A finite volume approach is proposed to model transport processes electrochemical reactions focusing on pos...

‎ In this paper, the stand-alone photovoltaic system for cathodic protection of underground pipelines is presented. The proposed system offers continuous and automatic adjustment of the applied voltage so that the buried pipelines receive the exact current. A modified perturb and observe (P&O) algorithm for maximum power point tracking (MPPT) is used to improve dynamic and steady state performa...

background & aim: lumbosacral pain is extremely common as age increases. spinal instrumentation is sometimes recommended for lumbar canal stenosis and disk herniation surgery. this study aimed at studying the frequency of instrumentation in patients referring to our center. methods & materials/patients: this retrospective cross-sectional study included 1200 patients with low back and/or radicul...

localizing the optic disc (od) in retinal fundus images is of critical importance, since it is very similar to hard exudates (found in pathology) in color and brightness. because of the importance of od localization in clinical applications, many techniques have been developed. in this paper, we present the results obtained from two methods, correlation and least square, to approximate the opti...
