    Journal of Renewable Materials, Vol.9, No.9, pp. 1531-1540, 2021, DOI:10.32604/jrm.2021.015346

    Abstract In recent years, bamboo has been widely used in a broad range of applications, a thorough understanding of the structural characteristics of bamboo nodes is essential for better processing and manufacturing of biomimetic materials. This study investigated the complex anatomical structure for the nodes of two bamboo species, Indocalamus latifolius (Keng) McClure and Shibataea chinensis Nakai, using a high-resolution X-ray microtomography (μCT). The results show that the vascular bundle system in the nodal region of I. latifolius and S. chinensis is a net-like structure composed of horizontal and axial vascular bundles. Furthermore, the fiber sheath surrounding metaxylem vessels tended to… More >

    VGG-CovidNet: Bi-Branched Dilated Convolutional Neural Network for Chest X-Ray-Based COVID-19 Predictions

    Muhammed Binsawad1,*, Marwan Albahar2, Abdullah Bin Sawad1

    CMC-Computers, Materials & Continua, Vol.68, No.2, pp. 2791-2806, 2021, DOI:10.32604/cmc.2021.016141

    Abstract The coronavirus disease 2019 (COVID-19) pandemic has had a devastating impact on the health and welfare of the global population. A key measure to combat COVID-19 has been the effective screening of infected patients. A vital screening process is the chest radiograph. Initial studies have shown irregularities in the chest radiographs of COVID-19 patients. The use of the chest X-ray (CXR), a leading diagnostic technique, has been encouraged and driven by several ongoing projects to combat this disease because of its historical effectiveness in providing clinical insights on lung diseases. This study introduces a dilated bi-branched convoluted neural network (CNN)… More >

    Abstract The recent novel coronavirus (COVID-19, as the World Health Organization has called it) has proven to be a source of risk for global public health. The virus, which causes an acute respiratory disease in persons, spreads rapidly and is now threatening more than 150 countries around the world. One of the essential procedures that patients with COVID-19 need is an accurate and rapid screening process. In this research, utilizing the features of deep learning methods, we present a method for detecting COVID-19 and a screening model that uses pulmonary computed tomography images to differentiate COVID-19 pneumonia from healthy cases.

    Abstract The bioactive triterpenoid 3-oxo-6-β-hydroxy-β-amyrin (1) has been isolated from multiple plant sources. In this study, chloroform fraction of Pistacia integerrima extract was processed for the isolation of the compound. The compound identity was confirmed by advanced spectroscopy technique. X-ray crystallography was applied for molecular structure confirmation. In addition, compound 1 was screen for its activity on reversal of MDR (multidrug resistance) mediated by P-gp (P-glycoprotein). This was accomplished by using rhodamine123 exclusion on multidrug-resistant human ABCB1 gene transfected mouse T-lymphoma cell line. Outcomes revealed that MDR reversing effect was comparable to verapamil as positive control in vitro. Treatment of TPA-induced… More >

    Real-Time Anomaly Detection in Packaged Food X-Ray Images Using Supervised Learning

    Kangjik Kim1, Hyunbin Kim1, Junchul Chun1, Mingoo Kang2, Min Hong3,*, Byungseok Min4

    CMC-Computers, Materials & Continua, Vol.67, No.2, pp. 2547-2568, 2021, DOI:10.32604/cmc.2021.014642

    Abstract Physical contamination of food occurs when it comes into contact with foreign objects. Foreign objects can be introduced to food at any time during food delivery and packaging and can cause serious concerns such as broken teeth or choking. Therefore, a preventive method that can detect and remove foreign objects in advance is required. Several studies have attempted to detect defective products using deep learning networks. Because it is difficult to obtain foreign object-containing food data from industry, most studies on industrial anomaly detection have used unsupervised learning methods. This paper proposes a new method for real-time anomaly detection in… More >

    Abstract Coronavirus (COVID-19) epidemic outbreak has devastating effects on daily lives and healthcare systems worldwide. This newly recognized virus is highly transmissible, and no clinically approved vaccine or antiviral medicine is currently available. Early diagnosis of infected patients through effective screening is needed to control the rapid spread of this virus. Chest radiography imaging is an effective diagnosis tool for COVID-19 virus and follow-up. Here, a novel hybrid multimodal deep learning system for identifying COVID-19 virus in chest X-ray (CX-R) images is developed and termed as the COVID-DeepNet system to aid expert radiologists in rapid and accurate image interpretation.

    Deep Learning in DXA Image Segmentation

    Dildar Hussain1, Rizwan Ali Naqvi2, Woong-Kee Loh3, Jooyoung Lee1,*

    CMC-Computers, Materials & Continua, Vol.66, No.3, pp. 2587-2598, 2021, DOI:10.32604/cmc.2021.013031

    Abstract Many existing techniques to acquire dual-energy X-ray absorptiometry (DXA) images are unable to accurately distinguish between bone and soft tissue. For the most part, this failure stems from bone shape variability, noise and low contrast in DXA images, inconsistent X-ray beam penetration producing shadowing effects, and person-to-person variations. This work explores the feasibility of using state-of-the-art deep learning semantic segmentation models, fully convolutional networks (FCNs), SegNet, and U-Net to distinguish femur bone from soft tissue. We investigated the performance of deep learning algorithms with reference to some of our previously applied conventional image segmentation techniques (i.e., a decision-tree-based method using… More >
