One-Class Classification (OCC) has been prime concern for researchers and effectively employed in various disciplines. But, traditional methods based one-class classifiers are very time consuming due to its iterative process and various parameters tuning. In this paper, we present six OCC methods and their thirteen variants based on extreme learning machine (ELM) and Online Sequential ELM (OSEL...
PURPOSE To determine whether volumes based on the contours of the mucosal surface instead of the oral cavity can be used to predict grade ≥3 acute oral mucosa toxicity in patients with locally advanced nasopharyngeal carcinoma (LANPC) treated with concurrent intensity-modulated radiation therapy (IMRT) and chemotherapy. METHODS AND MATERIALS A standardized method for the oral cavity (oral cav...
MicroRNAs (miRNAs) are short nucleotide sequences that form a typical hairpin structure which is recognized by a complex enzyme machinery. It ultimately leads to the incorporation of 18-24 nt long mature miRNAs into RISC where they act as recognition keys to aid in regulation of target mRNAs. It is involved to determine miRNAs experimentally and, therefore, machine learning is used to complemen...
Given a set of spatial objects, our task is to assign all the objects to the minimum number of service sites and to find the regions for building these service sites. Each service site has a coverage region (i.e., an area of service) and a capacity (i.e., a maximum number of objects it can serve, called k-constraint). The service sites can provide service for objects located within the coverage...
Recent functional neuroimaging studies have revealed that occipital or visual cortical areas in individuals blinded in o_r around birth are metabolically active during tactile, auditory and cognitive stimulation. These findings suggest that in the early blind (EB) the areas that are normally engaged by visual stimulation process non-visual information (a phenomenon referred to as cross-modal re...
We previously showed that nordihydroguaiaretic acid (NDGA) and other antioxidants inhibit the resumption of meiosis in oocyte-cumulus complexes (OCC) and denuded oocytes (DO). Because NDGA is well known to be an inhibitor of lipoxygenases (LOX), we assessed whether other LOX inhibitors influence spontaneous germinal vesicle breakdown (GVBD) in OCC and DO. Spontaneous GVBD in rat OCC obtained fr...
Background: In contrast to pharyngo-laryngeal cancer, definitive radiation-chemotherapy of advanced oral cavity cancer (OCC) results in inferior disease control rates. Surgery in combination with radiation +/concomitant chemotherapy is therefore the treatment of choice for squamous cell OCC stages >/=pT1-2pN0-1. Modern intensity modulated radiation techniques (IMRT) allow more conformal dose di...
There is an ever-increasing demand for more complex transactions and higher throughputs in transaction processing systems leading to higher degrees of transaction concurrency and, hence, higher data contention. The conventional two-phase locking (2PL) Concurrency Control (CC) method may, therefore, restrict system throughput to levels inconsistent with the available processing capacity. This is...
محدود بودن سطح جنگل های دنیا و تخریب شدید آن از یک طرف و افزایش روز افزون مصرف کاغذ و محصولات کاغذی هم گام با ازدیاد جمعیت و پیشرفت تکنولوژی از طرف دیگر، اهمیت بازیافت کاغذ در صنایع کاغذسازی را ضروری ساخته است. متاسفانه بازیافت کاغذ علی رغم مزیت های اقتصادی و زیست محیطی، به علت فرآیندهای متناوب تولید باعث کوتاه شدن الیاف خمیرکاغذ و ایجاد نرمه ها و ریزه الیاف می شود که این امر منجر به کاهش شدید ...
چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
