Attribute-based encryption provides fine-grained access control, ensuring data security in edge computing. However, existing access control schemes face issues such as high computational complexity due to bilinear pairing and key escrow with a single authority, which limit their effectiveness for lightweight terminal devices. To address these challenges, we propose a lightweight and key escrow-free access control scheme on encrypted data. This scheme replaces bilinear pairing with fast elliptic curve scalar multiplication, transferring most computational tasks to edge servers while preserving privacy, thus alleviating the computational burden on terminal devices. Additionally, we design a blockchain-based distributed key management method that allows multiple edge servers to distribute private keys collaboratively, resolving the key-escrow issue. Security analysis and performance evaluation demonstrate that our scheme effectively ensures data confidentiality, resists collusion attacks, and achieves high computational efficiency on the user side with low storage overheads, making it highly suitable for lightweight devices in edge computing.

It is widely recognized that the timely acquisition and presentation of accurate physiological data is a vital aid to the anaesthesiologist in monitoring and maintaining the well-being of a patient undergoing surgery. Collecting, storing, synchronizing, integrating, evaluating, and retrieving pertinent information from patient data remains very difficult due to limited computer power, the need for specialized software, inconsistency between monitoring devices, and inadequate data storage. This paper introduces the general steps of data acquisition in anaesthesia and summarizes some data acquisition systems. It also introduces some applications of the burgeoning field of artificial intelligence (AI) to data acquisition, illustrating how AI techniques may be used to advantage to assist the anaesthesiologist in monitoring and interpreting such data. © 2023 IEEE.

A great potential of various learning environment in mobile learning application can clearly be seen in current pandemic situation. The accessibility of the learning resources needs to be available from anywhere anytime despite having strong or poor internet connection. It has motivated researchers to imply context-aware capability in improving the accessibility of the learning resources. This paper presents a development process of Mudahnya BM mobile application that follows a fundamental concept of Mobile Cloud Learning (MCL). Mudahnya BM is an application to learn basic Malay language for learner 7–12 years old. The injection of extrinsic and intrinsic context-aware help the application to improve the reasoning process for finding available learning resources from service providers. Semantic-based approach is applied in the reasoning process. This study involved the end users for evaluation purposes. 33 randomized scenarios have been tested using One-Sample Wilcoxon Signed Rank test.

As real environments are quite complex, multiple-input-multiple-output (MIMO) channels should be characterized by the multidimensional-multirelational models. Tensor linear algebra has been emerging as a powerful and promising tool for such MIMO channel modeling and estimation. However, to the best of our knowledge, there hardly exists any algebraic framework of MIMO channel equalization when the channel is modeled as an arbitrary-dimensional transfer tensor (a tensor whose entries are all rational z-functions). In this work, we first propose a new method based on the projection, namely, 'projection-based method,' to determine whether a given transfer tensor is a full-rank tensor or not and carry out the inversion of an invertible transfer tensor. Our idea is employing the projection subspace of the system transfer tensor to simplify the pertinent inversion process. Second, we design the finite-impulse-response (FIR) realization to approximate the inverse of an arbitrary transfer tensor such that all entries of the approximated inverse transfer tensor are finite-degree polynomials of z. Third, we also analyze the computational and memory complexities required by our proposed new projection-based method for checking the full-rank condition of a given transfer tensor and for undertaking the tensor inversion. Our developed new theories and analysis in this work can be applied to determine the FIR model-orders of an approximated inverse MIMO transfer tensor often encountered in signal processing, control, communications, etc. © 2007-2012 IEEE.

Accurate segmentation of kidney ultrasound (KUS) images is of great significance for the diagnosis of kidney diseases. However, KUS images have challenges such as low contrast, large size variations, and acoustic shadow interference. In addition, obtaining labeled data is a major challenge in the field of medical image segmentation. This paper proposes a dual-branch hybrid CNN Transformer combined with a dual teacher semi-supervised segmentation network (DHCT-DT) based on the MT model. The reliability of guidance can be improved between two teachers by constructing consistency regularization constraints. The U-Net architecture is employed between the main teacher and student model. The auxiliary teacher model adopts a dual-branch hybrid CNN Transformer architecture. The multi-scale channel fusion attention mechanism (MSCF) is introduced to capture the feature correlation information of KUS images at different scales and channels. Two different training methods can combine their advantages to fully extract local and global information from images. To demonstrate the applicability of the proposed method, experiments were conducted on two datasets: a KUS dataset and a breast ultrasound (BUS) dataset. Both datasets demonstrated the most competitive segmentation performance. For example, in a semi-supervised experiment using only 10% labeled data in the BUS dataset, the Dice coefficient, Jaccard coefficient, HD, and ASSD reached 82.28%, 76,36%, 13.36mm, and 3.71mm.

With the fast growth of conversational AI, it is very important that these systems can handle religion and cultural sensitivity correctly. New, cutting-edge models like BERT, mBERT (multilingual BERT), and XLM-RoBERTa are very good at many types of natural language processing. But not a lot is known about how well they talk and act about their religious views. The dataset primarily contains content related to Christianity, Islam, and Hinduism, reflecting their prevalence in online discussions and AI training corpora. AIs need to learn how to deal with harsh words, social nuances, and touchy topics where they can talk about religion. Artificial intelligence systems could give answers that don't seem to be legit or different meaning which are very sensitive. This is a big ethical *** look at how well BERT, mBERT, and XLM-RoBERTa can handle religious and cultural situations in this study. We focus on how well they do across languages using the PAWS-X dataset. PAWS-X is a good tool for testing cross-lingual transfer because it has goals for finding paraphrases in a number of different languages. This lets us see how well these models understand complex meanings in a variety of linguistic and cultural settings. We use the dataset to test how well the model works in talks about Hinduism, Islam, and Christianity, which are very sensitive to cultural and religious *** see how well these models can understand underlying cultural differences and come up with suitable responses, we test them on religious sentence pairs as part of our methodology. We test both their language skills and their ability to stay sensitive when religious or doctrinal information is present. We also look into their cross-lingual transfer skills to see how well they work in different religious meaning. BERT, mBERT, and XLM-RoBERTa perform well in basic tasks but struggle with religious and cultural nuances. BERT and mBERT handle multiple languages effectively but often falter in uncle

This paper explores the benefits, challenges, and implications of integrating social media platforms into mobile government and examines its impact on enhancing citizen engagement and improving service delivery. Social media can incorporate citizen-government interactions by enabling the realtime communication, fostering transparency, and promoting public participation. Government agencies can leverage social media platforms to reach citizens directly, with different demographic characteristics, disseminate information efficiently, and get valuable feedback. Different successful use cases discussed, where social media has been employed in mobile government initiatives, such as during emergencies cases, policy formulation, and service promotion. Using the systematic Literature Review, the results show one key benefit of leveraging social media in mobile government platforms is enhanced citizen engagement and increase the user satisfaction. Social media creates interactive spaces where citizens can voice opinions, express concerns, and participate in decision-making processes. It facilitates the formation of virtual communities and encourages collaboration between the user and the service provider.
