Abstract In the evolving landscape of the smart grid (SG), the integration of non-organic multiple access (NOMA) technology has emerged as a pivotal strategy for enhancing spectral efficiency and energy management. However, the open nature of wireless channels in SG raises significant concerns regarding the confidentiality of critical control messages, especially when broadcasted from a neighborhood gateway (NG) to smart meters (SMs). This paper introduces a novel approach based on reinforcement learning (RL) to fortify the performance of secrecy. Motivated by the need for efficient and effective training of the fully connected layers in the RL… More >

Abstract Background: For patients with lung cancer, timely identification of new lung lesions as infectious or non-infectious, and accurate identification of pathogens is very important in improving OS of patients. As a new auxiliary examination, metagenomic next-generation sequencing (mNGS) is believed to be more accurate in diagnosing infectious diseases in patients without underlying diseases, compared with conventional microbial tests (CMTs). We designed this study to find out whether mNGS has better performance in distinguishing infectious and non-infectious diseases in lung cancer patients using bronchoalveolar lavage fluid (BALF). Materials and Methods: This study was a real-world retrospective review… More >

Abstract When designing and optimizing the hull of vehicles, their sound quality needs to be considered, which greatly depends on the psychoacoustic parameters. However, the traditional psychoacoustic calculation method does not consider the influence of the real human ear anatomic structure, even the loudness which is most related to the auditory periphery. In order to introduce the real physiological structure of the human ear into the evaluation of vehicle sound quality, this paper first carried out the vehicle internal noise test to obtain the experimental samples. Then, the physiological loudness was predicted based on an established More >

Abstract Feature Selection (FS) is an important problem that involves selecting the most informative subset of features from a dataset to improve classification accuracy. However, due to the high dimensionality and complexity of the dataset, most optimization algorithms for feature selection suffer from a balance issue during the search process. Therefore, the present paper proposes a hybrid Sine-Cosine Chimp Optimization Algorithm (SCChOA) to address the feature selection problem. In this approach, firstly, a multi-cycle iterative strategy is designed to better combine the Sine-Cosine Algorithm (SCA) and the Chimp Optimization Algorithm (ChOA), enabling a more effective search… More >

Abstract Standalone systems cannot handle the giant traffic loads generated by Twitter due to memory constraints. A parallel computational environment provided by Apache Hadoop can distribute and process the data over different destination systems. In this paper, the Hadoop cluster with four nodes integrated with RHadoop, Flume, and Hive is created to analyze the tweets gathered from the Twitter stream. Twitter stream data is collected relevant to an event/topic like IPL- 2015, cricket, Royal Challengers Bangalore, Kohli, Modi, from May 24 to 30, 2016 using Flume. Hive is used as a data warehouse to store the… More >

Abstract Accompagner l’entourage d’un patient atteint de maladie grave, évolutive ou terminale est une obligation légale (loi 99, art. L. 1er B) et nécessite des professionnels éclairés sur les mécanismes spécifiques. Objectif : découvrir les mécanismes psychoadaptatifs familiaux lors de la phase terminale. Méthode : la méthode était qualitative avec une observation participante dans un service de soins palliatifs entre 2016 et 2020. Résultats : l’observation de 649 familles révèle des détresses spécifiques, une relation soignante et/ou fusionnelle et un pacte dénégatif sur le mourir. L’absence de communication familiale sur le mourir est protectrice. Conclusion : More >

Abstract The Covid-19 outbreak has an unprecedented effects on people's daily lives throughout the world, causing immense stress amongst individuals owing to enhanced psychological disorders like depression, stress, and anxiety. Researchers have used social media data to detect behaviour changes in individuals with depression, postpartum changes and stress detection since it reveals critical aspects of mental and emotional diseases. Considerable efforts have been made to examine the psychological health of people which have limited performance in accuracy and demand increased training time. To conquer such issues, this paper proposes an efficient depression detection framework named Improved… More >

Abstract La recherche présentée dans cet article propose une approche qualitative de qualification d’ambiances sonores dans un espace urbain. La démarche combine une série de mesures psychoacoustiques réalisées in situ à partir d’une gamme complémentaire de capteurs sonores avec une évaluation qualitative réalisée par les acteurs de ces environnements. Les expérimentations menées dans la commune de Sidi Bou Saïd montrent la faisabilité de la démarche, l’intérêt de combiner mesures quantitatives et réalités sonores perçues, tout comme l’opérationnalisation possible de l’approche qualitative permettant de qualifier des ambiances sonores dans un riche environnement urbain.

Abstract Mexico is the main producer, consumer and exporter of avocado in the world, being Michoacan the main producer state contributing more than 80% of the national production. There are phytopathogens that decimate the production causing the death of the tree. Root samples were collected in avocado trees that showed the characteristic symptomatology of the disease known as avocado sadness, the sampling was carried out in four of the main avocado producing towns, in the state of Michoacan, Mexico. The isolation consisted in sowing root tissue in Petri dishes with V8^®-PARPH culture medium, subsequently they were identified More >

Abstract An important study in species of the genus Eupatorium, that inhabits other parts of the world, was conducted in the search for new molecules with pharmacological activities, thus showing that it is a potential source of novel secondary metabolites. We reviewed the number of Eupatorium species that have been described in the State of Michoacan, and that can be available for harvesting, to make a phytochemical screening. It was found that 69 Eupatorium spp are growing in 69% of the Michoacan territory. Within this group there are ten species used in Mexican traditional medicine. It was evident More >
