The future sixth-generation(6G) paradigm aims to seamlessly integrate communication and environmental sensing capabilities into a single radio signal, promising improved efficiency and cost-effectiveness through simultaneous data communications and environmental perception. At the core of this evolution, orthogonal frequency division multiplexing(OFDM) and its advanced waveforms emerge as pivotal for integrated sensing and communications(ISAC). This study introduces a concise and unified ISAC waveform design framework based on orthogonal multicarriers. This framework supports versatile applications of OFDM and its derivative waveforms within a generalized ISAC system, marking a significant leap in integrating communication and sensing capabilities. A distinguishing feature of this framework is its adaptability,allowing users to intelligently select modulation strategies based on their specific environmental needs. This adaptability optimizes performance across diverse scenarios. Central to our innovations is the proposal of discrete Fourier transformspread OFDM with index modulation(DFT-S-OFDM-IM). This framework is paired with newly proposed signal processing methods for single-input single-output and multiple-input multiple-output(MIMO) systems. Extensive evaluations highlight DFT-S-OFDM-IM's superiority, including dramatically reduced peak-to-average power ratios(PAPRs), competitive communication performance, and exceptional sensing capabilities, striking an elegant balance between communication capacity and environmental sensing precision.

As Industry 4.0 rapidly advances, optimizing energy and performance in industrial wireless sensor networks (IWSNs) for the Industrial Internet of Things (IIoT) is critical. Addressing the NP-hard challenge of IWSN clustering, this article introduces a novel multiobjective model to balance energy consumption and enhance service quality. Based on this model, a new energy-saving cluster routing protocol called CNCMSA-ECRP was designed. The protocol comprehensively considers four key indicators: 1) total residual energy;2) average network delay;3) average network packet loss rate;and 4) average distance from cluster heads (CHs) to the base station (BS), with the goal of achieving overall optimization of network performance. The CNCMSA-ECRP protocol employs our newly proposed chaotic niching clone moth swarm algorithm (CNCMSA). The algorithm introduces chaotic mapping operators in the initialization phase and clonal and niching operators in the evolution phase, enhancing the search capability and diversity of the algorithm, as well as improving clustering efficiency and network stability. Comparative experiments with four existing advanced clustering schemes—LEACH-C, EEHCHR, OptGACHE, and ESCVAD—demonstrate that CNCMSA-ECRP achieves at least a 16.38% increase in network lifespan and significantly reduces average data transmission delay and packet loss rate by at least 1.84% and 17.76%, respectively. This research provides a novel solution to the clustering routing problem in IWSN. © 2014 IEEE.

The most innovative Service-Optimized Logging for Resource Allocation (SOL-RA) is in situations that support 6G connection. The CyberTwin architecture optimizes the quality of service provided to end users in 6G communications by using the dependability of terahertz connections and interactions of a machine-type nature. Elastically sharing elastic resources among users is made possible by the proposed resource allocation strategy, which makes use of proprietary logger functions. This ensures that efficient allocation is achieved without overlapping or lengthy wait periods. Within the framework of SOL-RA, a categorization mechanism is implemented for dense requests, which differentiates them as either stationary or priority services. Resource allocations are dynamically done based on this categorization, which enhances the organization's responsiveness to different needs. Through a tree classifier learning mechanism, CyberTwin logs play an essential part in the processing of requests and the preparation of resources. This helps to ensure that resources are distributed without inefficiency. Requests that are generating a backlog are identified and processed in parallel by the system, which significantly reduces the amount of time that is wasted waiting. In order to guarantee a specialized distribution for the categorized outputs, resource allocations are directed by CyberTwin data logs. An examination of the performance of the SOL-RA scheme takes into account important metrics such service latency, service backlog, resource usage, and request-to-response ratio. This research offers insights into the efficacy of the scheme in maximizing service quality and resource consumption in 6G settings. © The Author(s) 2025.

Fruits are absolutely delicious for the most part, but more importantly, they are good for healthy life. Fruits are nature's candy and offer all sorts of health benefits besides the great taste. They provide necessary nutrients to the body so that it will not be susceptible to disease or other ailments. Fruits contain enough fiber to keep our digestive system in top health form. Fruits also helps to regulate the water level in body as well as your blood sugar levels, which means that will usually feel hungry less often if we consumes a lot of fruits. The easier it is for people to recognize that a fruit is ripe and ready for selling at the market allows the farmers, in some cases, to sell their crop early before it would normally spoil. If we look closely, we see that many times people don't buy something because it appears rotten or way past its peak ripeness, which demonstrates how products spoil right on time. This study proposed a user-convenient system for fruit ripeness detection using the convolutional neural network (CNN) based on RipeNet structure. © 2025 IEEE.

The rise of fake news on social media has made it important to find effective strategies for assessing news credibility. This study explores how using comment summarization tags on Facebook and Twitter might help users determine if news is credible. We conducted interviews and think-aloud sessions with N=18 Australian and New Zealander participants who actively use these platforms. Participants interacted with true and fake news posts on their news feeds using a Chrome extension, and their thoughts on news credibility were recorded. We found that participants who saw comment summarisation tags were more accurate in determining news credibility. These findings show the effectiveness of comment summarisation tags in evaluating social media news posts (SMNPs). Our study provides insights into social media users’ strategies and platform features to assess credibility and respond to misinformation. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Short videos and reels have emerged as a new method for conveying visual information on social media. These videos often include misleading superimposed captions that create doubt in viewers’ minds. With the rise of misinformation through platforms like TikTok and more people using social media for news, it is important to understand how users assess and interact with high and low-credibility short reels. We conducted a qualitative study with N=24 social media users in Australia to examine the impact of misleading captions on engagement with COVID-19-related videos. Our findings provide recommendations for supporting users when viewing misleading multimodal video posts. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Feature selection is a cornerstone in advancing the accuracy and efficiency of predictive models, particularly in nuanced domains like socio-economic analysis. This study explores nine distinct feature selection methods, utilizing a heart disease dataset as a representative model for complex socio-economic systems. Our findings identified four universally recognized features as critical across all selection methods. However, the divergence in significance attributed to other features by different methods underscores the inherent variability in selection techniques. When the top four features were incorporated into twelve classification models, a noticeable surge in predictive accuracy was observed, emphasizing their foundational role in enhancing model outcomes. The variations among methods stress the need for a methodical and discerning approach to feature selection, especially in data-rich socio-economic landscapes. As we venture further into an era defined by data-driven decision-making, rigour and precision in feature selection become indispensable. Future research should extend this approach to broader datasets, ensuring the robustness and adaptability of our findings. © The author(s) 2025.

Blockchain, as an emerging technology, has been widely studied by the researchers from academia and industry. Alliance chain, as an important form of blockchain, is often applied to smart grids, smart city and the Internet of Things to ensure the authenticity and reliability of data. Practical Byzantine Fault Tolerance (PBFT) algorithm is a key technology to ensure data consistency in the alliance chains, and it plays a critical role in improving system performance, security and scalability. However, with the increase of the number of nodes and transactions, the ability of PBFT to process transactions is challenged. In particular, PBFT’s linear transaction processing also limits its ability to process transactions in parallel. In view of the problems existing in PBFT, this paper studies the consensus mechanism optimization, and puts forward a consensus mechanism with better performance. In this paper, in order to solve the problem of weak parallel transaction processing capability of PBFT, we propose a novel Consensus Mechanism based on Dynamic Sharding (CMDS). CMDS firstly constructs a dynamic fragmentation model based on consistent hash algorithm to segment nodes, and then constructs a voting consensus mechanism based on reputation weight to achieve global state consistency. The experimental results show that CMDS can significantly improve the ability of parallel transaction processing and the performance of blockchain system. © IFIP International Federation for information Processing 2025.
