In the present study, we analyzed p16, retinoblastoma (Rb), and cyclin D1 abnormalities in head and neck squamous cell carcinoma (HNSCC) tissues and cell lines from Korean patients. We found a 40% loss of heterozygosity at the D9S171 locus (9p21 region) these tissues. All eight of the HNSCC cell lines did not express the p16 protein, and in two of these cell lines (Amc-HN-6 and 8), this was due...
In this paper, we propose a deep neural network (DNN)-based automatic modulation classification (AMC) for digital communications. While conventional AMC techniques perform well for additive white Gaussian noise (AWGN) channels, classification accuracy degrades for fading channels where the amplitude and phase of channel gain change in time. The key contributions of this paper are in two phases....
Automatic modulation classification (AMC) techniques have applications in a variety of wireless communication scenarios, such as adaptive systems, cognitive radio, and surveillance systems. However, a common requirement to most of the AMC techniques proposed in the literature is the use of signal preprocessing modules, which can increase the computational cost and decrease the scalability of th...
Nowadays, adaptive modulation and coding (AMC) techniques can facilitate flexible strategies subject to dynamic channel quality. The AMC transceivers select the most suitable coding and modulation mechanisms subject to the acquired channel information. Meanwhile, a control channel or a preamble is usually required to synchronously coordinate such changes between transmitters and receivers. On t...
Two hundred twelve patients with colonization/infection due to amoxicillin-clavulanate (AMC)-resistant Escherichia coli were studied. OXA-1- and inhibitor-resistant TEM (IRT)-producing strains were associated with urinary tract infections, while OXA-1 producers and chromosomal AmpC hyperproducers were associated with bacteremic infections. AMC resistance in E. coli is a complex phenomenon with ...

کومارین و مشتقات آن به عنوان یک گروه از فعال ترین مواد شیمیایی آلی هستند که در طیف وسیعی از فعالیت های بیولوژیک کاربرد دارند که در این پایان نامه ثابت اسیدی دو مشتق کومارین به نام 7-آمینو-4-متیل کومارین(amc) و 7-آمینو 4-تری فلویورو متیل کومارین (afc) تعیین شد. به این منظور از روش تیتراسیون اسپکتروفتومتری استفاده شد و توسط نرم افزار matlab و روش کمومتری pka,mcr-alsبه دست آمد. به دلیل اهمیت مایس...
The Mobility Aircraft Availability Forecasting (MAAF) model requirements definition research effort was initiated to help the United States Air Force, Air Mobility Command (AMC) answer the question, “How can we accurately predict mission capable (MC) rates?” Unfortunately, getting a perfect prediction of aircraft MC rates is not possible, either now or anytime in the foreseeable future. Fortuna...
Succinyl-Leu-Leu-Val-Tyr-7-amido-4-methylcoumarin (Suc-LLVY-AMC), a fluorogenic endopeptidase substrate, is used to detect 20 S proteasomal activity from Archaea to mammals. An o-phenanthroline-sensitive Suc-LLVY-AMC hydrolyzing activity was detected in Escherichia coli although it lacks 20 S proteasomes. We identified PepN, previously characterized as the sole alanine aminopeptidase in E. coli...
