    Performance Analysis of Intelligent CR-NOMA Model for Industrial IoT Communications

    Yinghua Zhang1,2, Jian Liu1, Yunfeng Peng1, Yanfang Dong2, Changming Zhao3,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.125, No.1, pp. 239-257, 2020, DOI:10.32604/cmes.2020.010778

    Abstract Aiming for ultra-reliable low-latency wireless communications required in industrial internet of things (IIoT) applications, this paper studies a simple cognitive radio non-orthogonal multiple access (CR-NOMA) downlink system. This system consists of two secondary users (SUs) dynamically interfered by the primary user (PU), and its performance is characterized by the outage probability of the SU communications. This outage probability is calculated under two conditions where, a) the transmission of PU starts after the channel state information (CSI) is acquired, so the base station (BS) is oblivious of the interference, and b) when the BS is aware of the PU interference, and… More >

    Positional Hypoxemia from Persistent Left Superior Vena Cava Draining to the Left Atrium

    Naveed Rabbani1,*, Sarah Hofman DeYoung2, Ronald L. Gibson2, Jeffrey Conwell1, Jason F. Deen1

    Congenital Heart Disease, Vol.15, No.4, pp. 197-201, 2020, DOI:10.32604/CHD.2020.011527

    Abstract Persistent left superior vena cava (PLSVC) is a relatively common congenital venous anomaly that typically drains into the coronary sinus without hemodynamic significance. Rarely a PLSVC drains directly into the left atrium, forming a right-to-left shunt that can result in hypoxemia and potential paradoxical embolism. We present the case of a 2-year-old medically complex child on chronic mechanical ventilation with eventual diagnosis of episodic hypoxemia due to a PLSVC draining into the left atrium with position-dependent venous flow. The lesion was identified with contrast echocardiography and cardiac MRI. Subsequent occlusion with a vascular plug resulted in resolution of the child’s… More >

    Percutaneous Occlusion of Right Partial Anomalous Pulmonary Venous Connection with Dual Drainage to the Innominate Vein and the Left Atrium: A Unique Anatomical Finding

    Alejandro R. Peirone1,*, Alejandro E. Contreras2, Carolina Carrizo2, Mailén Konicoff2, Raúl O. Cayre3

    Congenital Heart Disease, Vol.15, No.4, pp. 267-274, 2020, DOI:10.32604/CHD.2020.013199

    Abstract A 43-year-old woman with a past medical history of aortic coarctation surgically repaired at the age of 3 years using an end-to-end anastomosis, presented with 2 years complain of increasing dyspnea and fatigue with exercise associated to frequent palpitations. During extensive work-up, she was found to have a partial anomalous pulmonary venous connection (PAPVC) with “dual drainage” represented by a communication between the right pulmonary veins draining into the left atrium and the innominate vein via an anomalous vein due to a persistence of early connections between the sinus of the right pulmonary veins and the cardinal veins system in… More >

    Comprehensive Network Analysis of Different Subtypes of Molecular Disorders in Lung Cancer

    Haoliang Zhang1,*, Xiaowei Xing2, Yang Liu1, Shuangli Li1, Weiyuan Li3

    Oncologie, Vol.22, No.2, pp. 107-116, 2020, DOI:10.32604/oncologie.2020.012494

    Abstract Lung cancer is the leading cause of death in cancer patients. Based on a modular and comprehensive analysis method, it is intended to identify their common pathogenesis. We downloaded data and analyzed differences in lung adenocarcinoma samples, lung squamous cell carcinoma samples, and normal samples. Co-expression analysis, enrichment analysis, and hypergeometric testing were used to predict transcription factors, ncRNAs, and retrospective target genes. We get 4596 differentially expressed genes in common differences in high multiples and clustered into 14 modules dysfunction. The 14 genes (including DOK2, COL5A1, and TSPAN8) have the highest connectivity in the dysfunction module and are identified… More >

    Jianzhong Li1, DexiangMei1, Dong Deng1, Imran Khan2, Peerapong Uthansakul3, *

    CMC-Computers, Materials & Continua, Vol.65, No.2, pp. 1571-1590, 2020, DOI:10.32604/cmc.2020.011822

    Abstract Non-orthogonal multiple access (NOMA) is one of the key 5G technology which can improve spectrum efficiency and increase the number of user connections by utilizing the resources in a non-orthogonal manner. NOMA allows multiple terminals to share the same resource unit at the same time. The receiver usually needs to configure successive interference cancellation (SIC). The receiver eliminates co-channel interference (CCI) between users and it can significantly improve the system throughput. In order to meet the demands of users and improve fairness among them, this paper proposes a new power allocation scheme. The objective is to maximize user fairness by… More >

    Jianfeng Guan*, Jiawei Li, Zhongbai Jiang

    Intelligent Automation & Soft Computing, Vol.25, No.1, pp. 131-141, 2019, DOI:10.31209/2018.100000050

    Abstract The traditional web anomaly detection systems face the challenges derived from the constantly evolving of the web malicious attacks, which therefore result in high false positive rate, poor adaptability, easy over-fitting, and high time complexity. Due to these limitations, we need a new anomaly detection system to satisfy the requirements of enterprise-level anomaly detection. There are lots of anomaly detection systems designed for different application domains. However, as for web anomaly detection, it has to describe the network accessing behaviours characters from as many dimensions as possible to improve the performance. In this paper we design and implement a Multidimensional… More >

    Oncologie, Vol.22, No.1, pp. 35-42, 2020, DOI:10.32604/oncologie.2020.012485

    Abstract This study aimed to explore the expression and diagnostic performance of miR-586 and miR-493 in patients with osteosarcoma. We enrolled 63 patients with osteosarcoma treated between May 2016 and May 2019 as the experimental group and 55 healthy volunteers who underwent physical examination during the same period as the control group. We detected miR-586 and miR-493 expression in serum, normal bone tissue, and tumor samples. We also evaluated the relationship between clinical indicators and the miR-586 and miR-493 expression levels. The correlation between the serum and osteosarcoma tissue expression of miR-586 and miR-493 was examined by Pearson analysis. Furthermore, the… More >
