آنتن هایی با تراز گلبرگ کناری (sll) پایین و پهنای باند زیاد کاربردهای فراوانی در بسیاری از سیستم های راداری دارند. آنتن شبه یاگی به دلیل ساختار ساده ، سبک و ساخت آسان توجه بسیاری از طراحان آنتن را به خود جلب نموده است. از اینرو هدف این پایان نامه طراحی، آنالیز و شبیه سازی آرایه آنتن شبه یاگی پهن باند با تراز گلبرگ کناری پائین می باشد. از آنجا که پهنای باند آرایه آنتن از برهمکنش پهنای باند عناصر...
The ready-to-hand access of mobile devices creates the potential for practicing the novel approach of ‘seamless learning’, marked by continuity of the learning experience across different contexts. In a related note, the focus of Mobile-Assisted Language Learning is swinging to authentic or social mobile learning activities. In turn, we propose perspectives and approaches to address the need of...
Chronic lymphocytic leukemia/small lymphocitic lymphoma (CLL/SLL) is low-grade malignant lymphoprolipheration, that has tendency to convert to a higher-grade neoplasm over time. More common is the development of a diffuse large cell lymphoma or transformation into prolymphocytic cell population. In rare cases, 0.1-0.5% of patients develop multiple myeloma or Hodgkin's disease. We present 65-yea...
Recent GWAS have identified several susceptibility loci for NHL. Despite these successes, much of the heritable variation in NHL risk remains to be explained. Common copy-number variants are important genomic sources of variability, and hence a potential source to explain part of this missing heritability. In this study, we carried out a CNV analysis using GWAS data from 681 NHL cases and 749 c...
This work describes about the synthesis of the flat top power pattern of linear antenna array using differential evolution (DE) algorithm as an optimizing algorithm. In this work a flat top beam pattern of sharp transition (T), low Side Lobe Level (SLL) and very little ripple (R) has been achieved. To reduce the design cost of the feed network of the synthesized pattern, only the complex excita...
In this paper, the Invasive Weeds optimization( IWO) is exploited to produce the array radiation pattern that is nearest to the desired objective which exhibits sidelobe level (SLL) suppression and/or null placement. The inter-element position of even element Linear Arrays Array (LAA) is optimized and relocated whilst maintaining uniform excitation over the array aperture and the phase of the a...
STRIPS-like languages (SLLs) have fostered immense advances in automated planning. In practice, SLLs are used to express highly abstract versions of real-world planning problems, leading to more concise models and faster solution times. Unfortunately, as we show in the paper, simple ways of abstracting solvable real-world problems may lead to SLL models that are unsolvable, SLL models whose sol...
Sulfation of all macromolecules entering the secretory pathway in higher organisms occurs in the Golgi and requires the high-energy sulfate donor adenosine 3'-phosphate 5'-phosphosulfate. Here we report the first molecular identification of a gene that encodes a transmembrane protein required to transport adenosine 3'-phosphate 5'-phosphosulfate from the cytosol into the Golgi lumen. Mutations ...
Introduction. Determining the cause of shoulder pain is usually a challenge as many problems, such rheumatoid arthritis, osteoarthritis, osteonecrosis, rotator cuff arthropathy, traumatic fractures, conditions cervical vertebra, and neo-plasms, can produce similar symptoms. The diagnosis regarded incidental, however, chronic lymphocytic leukemia (CLL) by histopathological evaluation performed o...
Chronic lymphocytic leukemia/small lymphoma (CLL/SLL) is characterized by the accumulation of abnormal lymphocytes in blood, bone marrow, and lymphoid tissues, leading to a weakened immune system an increased risk infections for patients. The NCCN Guidelines CLL/SLL underscore need comprehensive evaluation multiple factors determine most appropriate treatment approach each patient. For frontlin...
