In this paper, we solve the MOSFET RF circuit ordinary differential equations with the waveform relaxation method, monotone iterative method, and Runge-Kutta method. With the monotone iterative method, we prove each decoupled and transformed circuit equation converges monotonically. This method provides an alternative in the time domain numerical solution of MOSFET RF circuit equations.
An important issue for neurophysiological studies of the visual system is the definition of the region of the visual field that can modify a neuron's activity (i.e., the neuron's receptive field - RF). Usually a trade-off exists between precision and the time required to map a RF. Manual methods (qualitative) are fast but impose a variable degree of imprecision, while quantitative methods are m...
conclusions it was concluded that ihlq might be a practical and useful tool for investigating hl for persian language speakers around the world. since hl is dynamic and its instruments should be regularly revised, further studies are recommended to assess hl with application of ihlq to detect its potential imperfections. results internal consistency and test-retest reliability (icc) of the fact...
Relevance feedback (RF) is an iterative process which refines the retrievals by utilizing user’s feedback marked on retrieved results. Recent research has focused on the optimization for RF heuristic selection. In this paper, we propose an automatic RF heuristic selection framework which automatically chooses the best RF heuristic for the given query. The proposed method performs two learning t...
The performance of multidimensional spatially selective radiofrequency (RF) pulses is often limited by their long duration. In this article, high-order, nonlinear gradients are exploited to reduce multidimensional RF pulse length. Specifically, by leveraging the multidimensional spatial dependence of second-order gradients, a two-dimensional spatial-spectral RF pulse is designed to achieve thre...
Anti-cyclic peptide antibodies (CCP/ACPA) are directed towards synthetic citrullinated peptides and are specific markers in diagnosis of Rheumatoid arthritis. This study aimed to compare the values and acuracy of the test in anticyclic citrullinated peptides (Anti-CCP /ACPA) antibodies, rheumatoid factor (RF), C-reactive protein (CRP) and disease activity index (PASI) in early diagnosis of untr...
آرتریت روماتوئید rheumatoid arthritis,(ra) یک بیماری خود ایمن است که یکی از معیارهای تشخیصی آن وجود فاکتور روماتوئید ( rheumatoid factor,rf ) در سرم بیماران می باشد. مطالعات نشان داده اند که بین بیماران آرتریت روماتوئید rf+ و rf- از نظر تظاهرات بافت شناسی ( histologic ) اختلافاتی وجود دارد. در این مطالعه میزان (crp) c-reactive protein و ایزوتیپهای iga rf و igm rf در 45 بیمار مبتلا به ra مورد سن...
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is a problematic pathogen posing a serious therapeutic challenge in the clinic. It is often multidrug-resistant (MDR) to conventional classes of antibacterial agents and there is an urgent need to develop new agents or strategies for treatment. Magnolol (ML) and honokiol (HL) are two naturally occurring diallylbiphenols which have be...
Hypothalamic tissues of female rats were extracted with 1.M acetic acid. The acidic extract was lyophilized and subjected to gel filtration on Sephadex column and assayed for follicle-stimulating hormone-releasing factor (FSH-RF) activity and luteinizing hormone-releasing factor (LH-RF) activity by estimating FSH and LH using the organ culture method of rat anterior pituitaries. FSH activity wa...
Background & Aim: According to the variable progression of rheumatoid arthritis(RA) determination of factors related with poor prognosis is necessary for appropriate treatment of these patients. In this cross section analytical study the aim was to determine the correlation between IgA RF, anti-MPO, anti-PR3 antibodies and clinical, radiological severity in patients with RA. Patients and Me...
