Security and Privacy for Modern Wireless Communication Systems, 2nd Edition
No full textWireless communication systems are undergoing rapid transformation, driven by the advent of 6G technologies, the proliferation of Internet of Things (IoT) devices, and the growing reliance on intelligent and connected infrastructure. As wireless networks expand in complexity and capability, ensuring security and privacy becomes increasingly vital—not only to protect sensitive data but also to maintain trust, system integrity, and operational reliability in critical applications such as remote healthcare, autonomous vehicles, and smart manufacturing.
This Special Issue, titled “Security and Privacy for Modern Wireless Communication Systems, 2nd Edition”, aims to address urgent challenges by highlighting the latest innovations in protocols, architectures, software, and hardware solutions designed to enhance the security and privacy of contemporary wireless networks. Unlike traditional systems, modern wireless environments must accommodate a diverse array of resource-constrained devices, ultra-low-latency applications, and emerging vulnerabilities introduced by technologies such as intelligent reflective surfaces, blockchain, edge/fog/cloud computing, and artificial intelligence (AI).
The 12 papers published in this Special Issue discuss a wide range of research topics. Several contributions focus on lightweight and quantum-resistant cryptography. These include discussions on the use of the CHERI architecture to create memory-safe intrusion detection systems and MLWE-based key exchange methods for post-quantum secure authentication. Other papers address network-level threats, proposing innovative solutions such as hybrid communication architectures, blockchain-based security for supply chains, and frameworks for cyber insurance to handle catastrophic cyber incidents. Additionally, this Special Issue highlights advancements in physical-layer security and edge security, including methods for physical-layer fingerprinting of LoRa devices, detection of covert communications, and the development of trust models within 6G edge–node–cloud ecosystems. Practical aspects of cybersecurity are also examined; several studies explore log-based forensic analysis, testbed validation, and real-time monitoring to detect remote access and file exfiltration

Exploring the Utility of Point-of-Care Testing for Diagnosing Snake Envenomation in Australian Snake Bites: A scoping review
No full textIntroduction
Most snake bites in Australia do not result in envenomation. However, when it does occur, envenomation can lead to a range of clinical syndromes, depending on the snake species involved. Diagnosis of envenomation, which relies primarily on laboratory investigations, poses a significant challenge when rapid identification of envenomation is essential for the timely administration of antivenom. Finding a solution to this challenge could enable earlier diagnosis and subsequent treatment of snake envenomation. This review assesses the existing literature on point-of-care testing methods for diagnosing snake envenomation across Australia.
Methods
Six relevant databases were searched using appropriate subject headings and keywords, related to “snake” AND “bite” AND “Australia” with no time or language restrictions. Two reviewers screened titles and abstracts and full text articles. Data from included studies was extracted in duplicate.
Results
1,260 articles were initially identified following removal of duplicates. After screening for eligibility, 12 relevant studies were identified. These articles explored four key areas of point-of-care testing in snake envenomation diagnosis: venom detection, coagulopathy detection, biomarker detection and cardiac assessment. No point-of-care test was found to sufficiently confirm envenomation to guide administration of antivenom in those with a suspected snake bite in Australia.
Conclusion
This review underscores the need for continued research to explore novel approaches for the rapid diagnosis of snake envenomation. Improved diagnostic tools could enhance patient outcomes and potentially allow rural and remote areas without laboratory facilities to diagnose or rule out envenomation without patient transfer. However, the current literature is limited, and existing point-of-care methods lack sufficient accuracy to guide clinical practice
Exploring the impact of replacement rates on carbon footprint in south-east Australian dairy herds
No full textContext:
Greater replacement rates in dairy herds lead to increased costs for rearing and/or purchasing replacement heifers and greater herd greenhouse gas (GHG) emissions.
Aims:
This study aimed to estimate current GHG emissions and potential improvements in net farm emissions (NFE) and emission intensity (EI) by reducing replacement rates (percentage of calvings in the herd in the year that were by first calving heifers) using a series of eight case study farms.
Methods:
The research was conducted by modelling eight Australian case study farms (five from northern Victoria/southern New South Wales and three from the Gippsland region) using farm-specific data. Data included herd structure, milk production, feed quality and quantity, and energy, fuel, and fertiliser usage. GHG emissions were estimated using the Dairy GHG Accounting Framework tool (ver. 14.5), calculating NFE and EI in megagram of carbon dioxide equivalents (Mg CO2e) and kilograms of carbon dioxide equivalent per kilogram of milk solids (kg CO2e/kg MS). The study modelled reducing the replacement rate by 5, 10, and 15 percentage points.
Key results:
The average (±s.d.) EI per kilogram of MS for the eight case study farms was 15.8 ± 3.5 kg CO2e/kg MS. A 15-percentage point reduction in replacement rate was estimated as leading to reductions in EI per kilogram of MS ranging from 0.9 to 1.7 kg CO2e/kg MS across the case-study farms. However, NFEs were estimated as increasing with reductions in replacement rate for five of the eight case study farms.
Conclusions:
Reducing the replacement rate can reduce EI (measured in kg CO2e/kg MS) but increase NFEs.
Implications:
The findings underscore the importance of considering both environmental factors, such as GHG emissions, and economic aspects, such as net farm income, when evaluating and implementing strategies for sustainable dairy farming
Short-term nitrogen enrichment induces sulfide intrusion in tropical oligotrophic seagrass meadows
No full textSediment sulfide stress on seagrasses is related to anthropogenic nutrient enrichment and substrate type (e.g., sandy or muddy). This study investigated if anthropogenic nitrogen (N) enrichment resulted in sulfide stress in tropical seagrass Thalassia hemprichii inhabiting sandy habitats. Anthropogenic input resulted in 3.4-fold increase in sediment δ15N, and increase in the sediment organic matter and fine fraction content. N enrichment increased sediment sulfur (S) content and caused higher δ34S depletion in sediment. Higher N availability contributed towards significant increase of T. hemprichii shoot density and leaf biomass. Conversely, it reduced the root biomass, and root branching index coinciding with depleted root δ34S values. Additionally, in the sandy sedi- ments the sediment Fe levels were lower than pristine conditions, suggesting Fe limitation and subsequent increased sediment sulfide intrusion into T. hemprichii roots. This highlights T. hemprichii growing in sandy sediments with low Fe levels are more prone to sulfide intrusion under N enrichment
Operational Economics of Renewable Energy-Hydrogen System With Hydrogen-Powered Transportation
No full textGreen hydrogen, produced from renewable energy sources, is undergoing a global resurgence as a clean energy solution driving decarbonization and fueling sustainable mobility. However, the major challenge facing the hydrogen economy is its scalability, particularly in the transportation sector. In response, this research develops innovative business models that utilize the low-emission attributes of green hydrogen to alleviate its financial constraints. The decrease in costs, in turn, can stimulate the growth of green hydrogen-powered transportation and facilitate the transition toward a carbon-neutral future. Key components of the proposed business workflow are elaborated, mathematical formulations of market parameters are derived, and case studies are presented to demonstrate the feasibility and efficiency of the proposed business models. Notably, the results demonstrate that the substantial costs associated with current hydrogen-powered transportation can be effectively subsidized in the proposed business models. Under current carbon emission prices of 92 USD/ton, the levelized cost of driving can be halved. Furthermore, these models create new opportunities for stakeholders across the entire hydrogen-powered transportation value chain, contributing to the overall prosperity and growth of the hydrogen industry. This highlights the significance and promising potential of the proposed business models within the green hydrogen credit framework
Marine habitat mapping of green turtle (Chelonia mydas) foraging grounds in the Northern Territory, Australia
No full textContext:
Green turtles (Chelonia mydas) are listed as vulnerable in Australia and are culturally significant to Indigenous Traditional Owners. However, their foraging habitats remain poorly understood, particularly in northern Australia.
Aims:
To map green turtle foraging habitats in the Northern Territory, through collaboration with Traditional Owners and ranger groups to support Sea Country management.
Methods:
Visual classifications of towed video transect data were used in a Support Vector Machine Learning Model to predict habitat across 379 km2 of remotely sensed satellite imagery, encompassing two green turtle foraging grounds within jointly managed parks, namely, Trepang Bay (Garig Gunak Barlu Marine Park) and Field Island (Kakadu National Park).
Key results:
Foraging turtle habitat; algae and seagrass made up 30% of the Trepang Bay and 18.05% of the Field Island foraging areas. The classification accuracy of the model showed a high level of agreement at both sites (0.63 and 0.75 respectively).
Conclusion:
These habitats provide good foraging grounds for green turtles and support different age classes for various behaviours, including resting and predator avoidance.
Implications:
The simple and repeatable field methods used in this study allow for ongoing monitoring by ranger groups. The findings will support conservation planning and management in the Northern Territory
Examining Stakeholder Perspectives and Strategies on Motivational and Experiential Aspects of Repeat Tourism
No full textPurpose: Although destination loyalty has been extensively studied within the context of tourism, there has been a notable lack of significant efforts to examine repeat tourism from the perspectives of multiple stakeholders. Based on stakeholder theory, this article aims to examine the viewpoints of a variety of stakeholders towards development of repeat tourism.
Design: 25 stakeholders representing both private and public sector of tourism operations participated in the study including government, hospitality, DMOs, academic and special interest tourism institutions. Data were collected through an in-depth interview with the participants in India. Owing to its vast geographical expanse, coupled with emerging destinations and evolving infrastructure India presents a diverse range of opportunities for repeat tourism.
Results: The stakeholders emphasised that the sociocultural diversity of India was the key factor that attracts tourists to enjoy a uniquely rewarding experience. The data were analysed using Leximancer, a sophisticated text mining tool. The findings emphasize the role of Design Science in Tourism (DST) framework to evaluate and integrate planning and implementation of strategies for the development of a repeat tourist market.
Originality: Attaining success in repeat tourism is a complex process and this study provides a multistakeholder outlook for the success of repeat tourists’ destinations. The study concludes with the theoretical and managerial contributions of the findings and highlights potential future research directions
Unlocking the repository: A strategy for increasing the uptake of green open access
No full textThis article uses a recent retroactive open access project undertaken by an Australian university library to reframe attitudes and approaches to author self-archiving. In addition to the view that open access is something to be sought for new research outputs – at the time of publication or immediately after an embargo period – the article proposes an ‘archival’ approach to open access, which treats institutional repositories as historical archives of knowledge to be made freely available to the public through periodic author self-archiving campaigns. Informed by data from the Curtin Open Knowledge Initiative’s Open Access Dashboard, this case study presents an alternative way of approaching the task of unlocking the repository archive through open access drives for older outputs. The article concludes that regular calls for author accepted manuscripts address some of the challenges facing the uptake of green open access by researchers. It demonstrates that it is possible to increase rates of author self-archiving through green open access drives
Drowning prevention strategies for migrant adults in Australia: a qualitative multiple case study
No full textDrowning is a global public health issue, with minority populations, including migrants, experiencing significant disparities in drowning. The World Health Organization recommends learning to swim as a strategy to reduce drowning. In Australia, migrants are identified as a priority population for drowning prevention, accounting for approximately one-third of all drowning deaths.
This study aimed to identify swimming and water safety programs aimed at adult migrant populations in Australia and to explore how these programs are meeting the needs of migrant adults.
Using a qualitative multiple case study methodology a desktop review was conducted of 30 publicly accessible swimming and water safety programs across Australia aimed at migrant communities. From this review, six programs were purposively selected for in-depth analysis. Interviews and focus groups with 63 participants (program, managers, swim teachers and program participants), were conducted, guided by the Health Belief Model and Theory of Planned Behaviour. Data was thematically analysed using a deductive approach.
Four overlapping key themes with 14 sub-themes were identified: (1) Motivations for establishing programs for migrant adults, (2) Perceived barriers to participation, (3) Addressing cultural and socio-economic determinants of health and (4) Factors and challenges to program success. Findings revealed that drowning among migrant communities was the catalyst for establishing programs, and that staff consciously design these swim programs to make programs accessible and relevant to migrants. This includes offering single-gender programs, providing culturally appropriate swimwear, having bilingual teachers, low or no cost participation fees and ensuring training pathways to employment in the aquatic industry.
Swimming and water safety programs that acknowledge and respond to migrants’ needs and characteristics offer multiple benefits beyond drowning prevention, including improved physical, social and mental health, and positive settlement experiences. These programs highlight the importance of acquiring water safety awareness, knowledge and skills, and how this can influence generational attitudes and behaviour towards drowning risk and water engagement. Drowning is a complex public health issue, with collaboration among multisectoral stakeholders required to create an impact and reduce inequities, especially for vulnerable populations such as migrant adults
