Detecting brain tumours is complex due to the natural variation in their location, shape, and intensity in images. While having accurate detection and segmentation of brain tumours would be beneficial, current methods still need to solve this problem despite the numerous available approaches. Precise analysis of Magnetic Resonance Imaging (MRI) is crucial for detecting, segmenting, and classifying brain tumours in medical diagnostics. Magnetic Resonance Imaging is a vital component in medical diagnosis, and it requires precise, efficient, careful, efficient, and reliable image analysis techniques. The authors developed a Deep Learning (DL) fusion model to classify brain tumours reliably. Deep Learning models require large amounts of training data to achieve good results, so the researchers utilised data augmentation techniques to increase the dataset size for training models. VGG16, Resnet50, and convolutional deep belief networks networks extracted deep features from MRI images. Softmax was used as the classifier, and the training set was supplemented with intentionally created MRI images of brain tumours in addition to the genuine ones. The features of two DL models were combined in the proposed model to generate a fusion model, which significantly increased classification accuracy. An openly accessible dataset from the internet was used to test the model's performance, and the experimental results showed that the proposed fusion model achieved a classification accuracy of 98.98%. Finally, the results were compared with existing methods, and the proposed model outperformed them significantly.

The study focuses on the transition from conventional energy sources to sustainable renewable energy (RE) in Palestine, particularly in the West Bank and Gaza Strip. The research aims to understand the relationship between key factors and residents' willingness to invest in the RE sector, with a specific focus on the impact of education. Using the unified theory of acceptance and use of technology, the study analyzes data from 400 residents through a questionnaire and employs ordinary least-squares regression analysis with Eviews 12. The key findings indicate that residents' inclination to invest in RE is significantly influenced by factors such as resource availability, knowledge level and power outages. Moreover, the study suggests that educated residents are more likely to invest in RE when factors such as knowledge, effort expectation, enabling conditions and resource availability are relatively high. The conclusion emphasizes the importance of policymakers' allocating sufficient funds to research and development to promote technological innovation in RE sources, thereby enhancing the population's energy efficiency. The study focuses on the transition from conventional energy to sustainable renewable energy in Palestine, particularly in the West Bank and Gaza Strip, to understand the relationship between key factors and residents' willingness to invest in the RE sector, with a specific focus on the impact of education.

United States Healthcare Data Breaches: Insights for nIST SP 800-66 Revision 2 from a Review of the nIST SP 800-66 Revision 1

引用

Journal of Information Security 2024年第2期15卷 232-244页

作者： mohammed mohammed Raoof Center for Information Systems & Technology Claremont Graduate University Claremont USA

Healthcare security and privacy breaches are occurring in the United States (US), and increased substantially during the pandemic. This paper reviews the national Institute of Standards and Technology (nIST) publication base as an effective solution. The nIST Special Publication 800-66 Revision 1 was an essential standard in US healthcare, which was withdrawn in February 2024 and superseded by SP 800-66 Revision 2. This review investigates the academic papers concerning the application of the nIST SP 800-66 Revision 1 standard in the US healthcare literature. A systematic review method was used in this study to determine current knowledge gaps of the SP 800-66 Revision 1. Some limitations were employed in the search to enforce validity. A total of eleven articles were found eligible for the study. Consequently, this study suggests the necessity for additional academic papers pertaining to SP 800-66 Revision 2 in the US healthcare literature. In turn, it will enhance awareness of safeguarding electronic protected health information (ePHI), help to mitigate potential future risks, and eventually reduce breaches.

针对水平井产量受水平井井筒射孔密度分布影响的问题,建立两种水平井射孔密度分布模式(即分别增大井筒入口段和出口段射孔密度)下的数值模型对水平井两相流动进行模拟;将模拟结果与实验结果进行对比,验证本研究数值模拟方法的可靠性,在此基础上采用数值模拟研究两种射孔密度分布模式下井筒各流型阶段总压降、气水两相流体表观速度、空隙率、液膜厚度和产气量、产液量的变化规律。研究表明,当水相流量保持不变时,随着空气流量的增加,总压降、气水两相流体表观速度增大,空隙率增加,液膜厚度减小;相较于增大出口段射孔密度,当入口段射孔密度增大时,产液量和产气量均增加,且产气量随着气体流量增加而增大;产液量在泡状流阶段增加,而达到弹状流—分层流过渡点后开始降低,进入分层波状流阶段后产液量开始增加;无因次产液量在增大井筒入口段射孔密度的模式下更大,且随着径向气相流量的增加而增大。
