رفتار میدان الکترومغناطیسی در یک محیط، توسط معادلات ماکسول و شرایط مرزی تعیین می شود. بنابراین با ایجاد شرایط مرزی مناسب می توان رفتار میدان را کنترل نمود. پرکاربردترین شرط مرزی، شرط رسانای الکتریکی کامل (pec) است که در فرکانس های مایکروویو، می توان از رساناهای خوب برای ایجاد آن استفاده کرد. شرط مرزی مفید دیگر، شرط رسانای مغناطیسی کامل (pmc) است. هر چند رسانای مغناطیسی وجود ندارد ولی رسانای مغن...
BACKGROUND Absolute lymphocyte count (ALC) in peripheral blood has recently been reported to be an independent prognostic factor in multiple myeloma (MM). Previous studies indicated that the absolute monocyte count (AMC) in peripheral blood reflects the state of the tumor microenvironment in lymphomas. Neither the utility of the AMC nor its relationship with ALC has been studied in MM. METHOD...
7-Amino-4-methylcoumarin (AMC) was previously shown to suppress pro-inflammatory cytokine production and prevent death in an endotoxic shock model in mice. In the present study, we investigated the effectiveness of AMC as a potential cytokine modulator in alleviating autoimmune diseases. We examined the efficacy and cytokine-modulatory activity of AMC in collagen-induced arthritis (CIA) in mice...
Our previous work demonstrated that abacus-based mental calculation (AMC), a traditional Chinese calculation method, could help children improve their math abilities (e.g. basic arithmetical ability) and executive function (e.g. working memory). This study further examined the effects of long-term AMC training on math ability in visual-spatial domain and the task switching component of executiv...
کدینگ و مدولاسیون تطبیقی (amc) روشی امیدبخش برای بهبود عملکرد طیفی سیستم های بی سیم چند ورودی و چند خروجی (mimo) در کانال های محوشدگی چند مسیره می باشد. در این پایان نامه روی فراهم کردن سیستم های کدینگ و مدولاسیون تطبیقی عملی جدیدی برای محیط های تک کاربره تمرکز می کنیم. اطلاعات حالت کانال (csi) در فرستنده برای تطبیق کردن نرخ ارسال یا بهره آنتن ها در سیستم چند آنتنه استفاده می شود. در تکنیک amc ...
background motion artifacts that degrade image quality of coronary ct angiography (ccta) in patients with high heart rates may be reduced with specific automatic motion correction algorithms (amc). conclusions ccta image quality improves significantly with amc in patients with high heart rates and reduces the proportion of non-diagnostic examinations. results mean heart rate during ccta was 61 ...
results amc-susceptible esbl-producing escherichia coli, klebsiella pneumoniae and k. oxytoca were identified as the causative agents in 31, 14, and 1 patients, respectively. thirty-nine (84.7%) out of 46 patients were successfully treated with oral amc. additionally, 2 (4.3%) patients’ urine cultures turned to be negative, though their clinical complaints and leukocyturia had continued. in the...
BACKGROUND Arthrogryposis multiplex congenita (AMC) is defined as nonprogressive congenital contractures that generally result from lack of fetal movement in utero. AMC is a feature of many congenital disorders caused by genetic, environmental, or other factors. One rare cause of AMC is maternal myasthenia gravis (MG). This is an autoimmune disorder, caused by antibodies to the nicotinic acetyl...
The peripheral blood absolute lymphocyte/monocyte count ratio at diagnosis (ALC/AMC-DX) predicts survival in classical Hodgkin lymphoma (cHL). However, a limitation of the ALC/AMC-DX is the inability to assess sequentially the host/tumor interaction during treatment. Therefore, we retrospectively examined the ALC/AMC ratio, as a surrogate marker of host immunity (ALC) and tumor microenvironment...
This paper extends analysis of the Adaptive Mixed Criticality (AMC) scheme for fixed-priority preemptive scheduling of mixed-criticality systems to include tasks with arbitrary deadlines. Both of the previously published schedulability tests, AMC-rtb and AMC-max are extended to cater for tasks with deadlines that may be greater than their periods. Evaluations show that the simpler method, AMC-r...
