    A Novel Fall Detection Framework Using Skip-DSCGAN Based on Inertial Sensor Data

    Kun Fang, Julong Pan*, Lingyi Li, Ruihan Xiang

    CMC-Computers, Materials & Continua, Vol.78, No.1, pp. 493-514, 2024, DOI:10.32604/cmc.2023.045008

    Abstract With the widespread use of Internet of Things (IoT) technology in daily life and the considerable safety risks of falls for elderly individuals, research on IoT-based fall detection systems has gained much attention. This paper proposes an IoT-based spatiotemporal data processing framework based on a depthwise separable convolution generative adversarial network using skip-connection (Skip-DSCGAN) for fall detection. The method uses spatiotemporal data from accelerometers and gyroscopes in inertial sensors as input data. A semisupervised learning approach is adopted to train the model using only activities of daily living (ADL) data, which can avoid data imbalance problems. Furthermore, a quantile-based approach… More >

    Soundscapes in Arab Cities: A Systematic Review and Research Agenda

    Tallal Abdel Karim Bouzir1,*, Djihed Berkouk2,3, Theodore S. Eisenman4, Dietrich Schwela5, Nader Azab2, Mohammed M. Gomma2,6, Samiha Boucherit7

    Sound & Vibration, Vol.58, pp. 1-24, 2024, DOI:10.32604/sv.2024.046723

    Abstract In the context of Arab cities, this study explores the intricate interplay between cultural, historical, and environmental elements that shape their unique soundscapes. The paper aims to shed light on this underrepresented field of study by employing a three-fold research approach: systematic review, a comprehensive literature review, and the formulation of a future research agenda. The first part of the investigation focuses on research productivity in the Arab world regarding soundscape studies. An analysis of publication trends reveals that soundscape research in Arab cities is still an emerging area of interest. Critical gaps in the existing body of literature are… More >

    Comprehensive Survey of the Landscape of Digital Twin Technologies and Their Diverse Applications

    Haiyu Chen1, Haijian Shao1,2,*, Xing Deng1, Lijuan Wang1, Xia Wang3

    CMES-Computer Modeling in Engineering & Sciences, Vol.138, No.1, pp. 125-165, 2024, DOI:10.32604/cmes.2023.027834

    Abstract The concept of the digital twin, also known colloquially as the DT, is a fundamental principle within Industry 4.0 framework. In recent years, the concept of digital siblings has generated considerable academic and practical interest. However, academia and industry have used a variety of interpretations, and the scientific literature lacks a unified and consistent definition of this term. The purpose of this study is to systematically examine the definitional landscape of the digital twin concept as outlined in scholarly literature, beginning with its origins in the aerospace domain and extending to its contemporary interpretations in the manufacturing industry. Notably, this… More >

    A novel prognostic gene signature, nomogram and immune landscape based on tanshinone IIA drug targets for hepatocellular carcinoma: Comprehensive bioinformatics analysis and in vitro experiments

    BOWEN PENG1, YUN GE1, GANG YIN2,3,*

    BIOCELL, Vol.47, No.7, pp. 1519-1535, 2023, DOI:10.32604/biocell.2023.027026

    Abstract Background: Tanshinone IIA, one of the main ingredients of Danshen, is used to treat hepatocellular carcinoma (HCC). However, potential targets of the molecule in the therapy of HCC are unknown. Methods: In this study, we collected the tanshinone IIA targets from public databases for investigation. We screened differentially expressed genes (DEGs) across HCC and normal tissues using mRNA expression profiles from The Cancer Genome Atlas (TCGA). Univariate Cox regression analysis and least absolute shrinkage and selection operator (LASSO) Cox regression models were used to identify and construct the prognostic gene signature. Results: Finally, we discovered common genes across tanshinone IIA… More >

    The Euthanasia Era: Grief Intervention in the Context of Anticipated Death

    À l’ère de l’euthanasie : la clinique du deuil en contexte de mort anticipée

    P. Laperle, M. Achille, D. Ummel

    Psycho-Oncologie, Vol.16, No.2, pp. 253-259, 2022, DOI:10.3166/pson-2022-0194

    Abstract Oncology and palliative care professionals benefit from considering the effect of euthanasia on their practice. Choosing the circumstances of one’s death is the zeitgeist, which impacts care trajectories. It becomes relevant to examine the influence of anticipated death (euthanasia or natural death) both on the patient and bereaved loved ones’ experience. We propose a relational approach and grief interventions based on the imprints left by death and the relational landscape of bereavement.

    Les soignants en oncologie et en soins palliatifs gagnent à considérer les effets de l’euthanasie sur leur pratique. Choisir les circonstances de sa mort est dans… More >

    Vers une approche psychoacoustique et qualitative des paysages sonores de la commune de Sidi Bou Saïd

    Mohamed Amin Hammami1 , Christophe Claramunt2

    Revue Internationale de Géomatique, Vol.30, No.2, pp. 215-243, 2020, DOI:10.3166/rig.2022.00113

    Abstract The research presented in this paper introduces a qualitative approach for the representation of urban sound scapes. The approach combines a series of in situ psychoacoustics measurements recorded with different sensors with a qualitative evaluation derived from human beings acting in these urban environments. The experiments realized in the city of Sidi Bou Saïd illustrate the potential of the combination of the quantitative and qualitative views, as well as demonstration of the feasibility of the whole approach when experimented in a real urban environment.

    Do Geographically Isolated Grasslands Follow the Principle of Island Biogeography in a Landscape Scale? Taking Poyang Lake Grassland as an Example

    Shiqi Luo1,3, Wenbo Chen2,3,*, Lei He4, Qiongbing Xiong1,3

    Phyton-International Journal of Experimental Botany, Vol.92, No.2, pp. 455-470, 2023, DOI:10.32604/phyton.2022.022466

    Abstract As one of the basic theories of biodiversity conservation, island biogeography has been widely accepted in the past decades. Originally, island biogeography was put forward and applied in oceanic environments. But later on, it was found out that the application was not only limited to oceanic islands, but also in terrestrial environments with relatively isolated conditions. In terms of biodiversity level, island biogeography generally focuses on a small scale, such as species diversity and genetic diversity. The studies of biodiversity on a large-scale based on island biogeography, such as ecosystem and landscape scales, were seldomly conducted. Taking Poyang Lake, the… More >

    Ahmed Abdulhakim Al-Absi1, Dae-Ki Kang2,*, Mohammed Abdulhakim Al-Absi3

    CMC-Computers, Materials & Continua, Vol.74, No.1, pp. 671-691, 2023, DOI:10.32604/cmc.2023.030262

    Abstract Sentiment analysis (AS) is one of the basic research directions in natural language processing (NLP), it is widely adopted for news, product review, and politics. Aspect-based sentiment analysis (ABSA) aims at identifying the sentiment polarity of a given target context, previous existing model of sentiment analysis possesses the issue of the insufficient exaction of features which results in low accuracy. Hence this research work develops a deep-semantic and contextual knowledge networks (DSCNet). DSCNet tends to exploit the semantic and contextual knowledge to understand the context and enhance the accuracy based on given aspects. At first temporal relationships are established then… More >

    Advances of Polyurethane Foams Derived from Lignin

    Hyoe Hatakeyama1,*, Tatsuko Hatakeyama2

    Journal of Renewable Materials, Vol.1, No.2, pp. 113-123, 2013, DOI:10.7569/JRM.2012.634111

    Abstract Lignin and saccharides are two major components of plants. Huge amounts of plant residues are obtained as by-products of large-scale industries, such as pulp and paper, bio-fuel and the food industry. In this paper, preparation of polyurethane (PU) foam directly from various kinds of industrial lignin and molasses, which have scarcely been utilized, is summarized based on our results obtained by recent investigation. A onestep reaction using hydroxyl groups of plant materials as an active site makes it possible to produce a wide variety of PU, such as foams, sheets, gels and composite matrix. In this paper, PU foams receive… More >
