PUVC: A novel position-based VANET caching framework built upon UAVs association
No full textThe rapid adoption of vehicular communication technologies has driven the development of the Vehicular Ad Hoc Network (VANET), which supports applications such as congestion control and resource allocation and serves as a critical component of automotive cyber-physical and industrial communication networks. Despite enhanced On- Board Units (OBUs), the VANET faces challenges from limited communication range, storage capacity, and highly dynamic topology, which collectively degrade Quality of Service (QoS) and increase network link load. In-network caching improves QoS by distributing content closer to vehicles. Meanwhile, recent advancements have refined VANET caching methodologies by enhancing traditional strategies, such as probabilistic caching, and integrating innovative communication frameworks, including Software-Defined Networking (SDN) and Named Data Networking (NDN). However, existing schemes often suffer from limited coverage and redundant rebroadcasts. To address these challenges, this paper proposes PUVC, a position-based UAV-assisted VANET caching framework in which a Central UAV disseminates popular content and Sub-UAVs maintain backups based on vehicle location and received signal strength. Road-constrained UAV mobility further improves transmission efficiency and mitigates topology-induced QoS degradation. Simulations in urban and highway scenarios show that PUVC reduces link load by over 74%, increases local satisfaction by more than 77%, and decreases data retrieval latency by 55%, demonstrating its effectiveness for QoS-aware industrial vehicular communication systems.</p
A systematic review investigating the characteristics and effectiveness of multi-level mental health interventions in sport
No full textConsensus has begun to emerge around the potential effectiveness of multi-level, mental health interventions within sport. The aim of this review was to evaluate the effectiveness of existing multi-level interventions aimed at enhancing mental health and wellbeing and/or reducing mental ill-health (depression, anxiety, eating disorders, gambling and alcohol use) within sport and identify key characteristics of effective multi-level interventions. The protocol was pre-registered with PROSPERO (CRD42023385320). We systematically searched PsycARTICLES, PsycINFO, Scopus, SPORTDiscus, and PubMed up to August 2025. This search yielded 1922 studies evaluating 12 different multi-level interventions. We examined methodological quality through the Mixed Methods Appraisal Tool and used a narrative synthesis. We provide evidence for the effectiveness of multi-level interventions in enhancing individuals’ mental health and/or reducing mental ill-health within amateur and collegiate level sport. Key characteristics of effective multi-level interventions included: engagement with key stakeholders and/or significant others, involvement of multiple sessions/points of contact and inclusion of multiple, targeted components. Methodological quality across the studies was mixed with evaluations lacking long term follow-up data and process evaluations and a paucity of interventions targeting the elite sport context, female participants, and/or gambling outcomes. </p
James Joyce’s Ulysses in the Limited Editions Club and other works: Recovering the forgotten role of literary agent Denyse Clairouin
No full textThis article recovers the largely forgotten role of Denyse Clairouin (1900–1945)—translator, literary agent, and French Resistance member—in the transatlantic circulation of Anglophone literature during the interwar period. Although Clairouin was a crucial intermediary for prominent American and British writers in France, her contributions have remained marginal within modernist and book-historical scholarship, in part because the archival record of her work is scattered and limited. Drawing on correspondence preserved in a previously unused private family archive, complemented by materials in archival collections in France, Britain, and the United States, the article reconstructs Clairouin’s professional formation as a translator and her subsequent emergence as one of the first literary agents in France specialising in translation rights.
The essay centres on Clairouin’s decisive intervention in the negotiations that enabled the Limited Editions Club’s 1935 edition of James Joyce’s Ulysses, illustrated by Henri Matisse. It shows that George Macy relied on Clairouin to make contact with Joyce and to manage relations with Joyce’s long-time legal adviser Paul Léon, whose cautious, control-oriented approach to rights and reputation often stalled negotiations. By bypassing Léon and appealing directly to Joyce, Clairouin helped secure permission for the edition and was instrumental in commissioning Stuart Gilbert’s prefatory apparatus, designed to make the novel legible to non-specialist bibliophiles. The article interprets the resulting friction between Léon’s legalistic model of protection and Clairouin’s relational model of controlled circulation as a revealing instance of competing modes of mediation within modernist publishing.
Finally, the essay situates Clairouin’s wartime activity and death in deportation within the broader problem of archival disappearance, arguing that agents’ work—especially women’s intermediary labour—was structurally vulnerable to both historiographical neglect and the material disruptions of war. Reconstructing Clairouin’s role thus reframes Ulysses’s transatlantic publishing history and demonstrates the explanatory power of agent-centred microhistory for book history.</p

Effect of vibration on automotive transmission radial lip seal leakage
No full textThe European Union’s regulatory mandate requirements for vehicular components include the integrity of sealing performance, mitigating leaks from fuel tanks and transmission systems in order to guard against environmental pollution. Non-compliance can result in significant costs for the OEM and their supplier base. The majority of the reported research regarding leakage from radial lip seals focuses on static analysis of leakage under a given set of laboratory conditions. However, in practice, seal conjunctions are often subjected to significant excitations due to vehicular vibration. In the current study, the case of a front-wheel drive vehicle, equipped with three-axle accelerometers and subjected to a comprehensive road test, is used as the basis for the development of a realistic representative test rig. The test rig is developed using bespoke components from the vehicle under investigation to assess the impact of the encountered natural frequencies on sealing performance in controlled laboratory conditions, when the system is subjected to controlled excitation. Experiments are conducted to evaluate leakage at the transmission interface, focusing specifically on the sealing system’s performance. The influence of driveshaft manufacturing processes using corundum grinding and subsequent surface topography upon leakage performance are also considered. Identified modal response frequencies are imposed upon the test rig using a shaker, whilst the seal leakage is measured. The importance of shaft roughness characteristics, such as topographical skewness upon seal leakage rate under various resonant conditions, are ascertained. The results indicate potentially significant leakage rates under excitation conditions, with a non-optimised shaft roughness profile.</p
Supplementary information files for "Recommended solutions for the disinfection of Ti-Zr-cu-pd bulk metallic glasses"
No full textSupplementary files for article "Recommended solutions for the disinfection of Ti-Zr-cu-pd bulk metallic glasses"Disinfection of medical devices is crucial to patient safety. Notably, an incorrect selection of disinfectant can damage the material surface and impact its performance. Ti-Zr-Cu-Pd bulk metallic glasses (BMGs) show considerable potential for biomedical use, however standard sterilisation protocols remain undeveloped. This study evaluates the effects of common clinical disinfection solutions, including NaOH, NaClO, and Virkon®, on Ti-Zr-Cu-Pd BMGs, to assess their impact on surface characteristics (chemical composition, surface free energy) and on biocompatibility (pre-osteoblast cells behaviour). The findings aim to inform practical guidelines for safe and effective cleaning and sterilisation of devices that contain these alloys.© The Author(s), CC BY 4.0</p
LLM-enhanced space-air-ground-sea integrated networks
No full textThe space-air-ground-sea integrated networking (SAGSIN) concept promises seamless global multimedia connectivity, yet two obstacles still limit its practical deployment. Firstly, high-velocity satellites, aerial relays and sea-surface platforms suffer from obsolete channel state information (CSI), undermining feedback-based adaptation. Secondly, data-rate disparity across the protocol-stack is extreme: terabit optical links in space coexist with kilobit acoustic under-water links. This article shows that a single large language model (LLM) backbone - trained jointly on radio, optical and acoustic traces - can provide a unified, data-driven adaptation layer that addresses both rapid CSI ageing and severe bandwidth disparity across the SAGSIN protocol- stack. Explicitly, an LLM-based long-range channel predictor forecasts the strongest delay-Doppler components several coherence intervals ahead, facilitating near-capacity reception, despite violent channel fluctuations. Furthermore, our LLM-based semantic encoder turns raw sensor payloads into task-oriented tokens. This substantially reduces the SNR required for high-fidelity image delivery in a coastal underwater link, circumventing the data rate limitation by semantic communications. Inclusion of these tools creates a medium-agnostic adaptation layer that spans radio, optical and acoustic channels. We conclude with promising open research directions in on-device model compression, multimodal fidelity control, cross-layer resource orchestration and trustworthy operation, charting a path from laboratory prototypes to field deployment.</p
Temporal uncertainty, spatial stressors and disrupted connections: temporary accommodation and family life, health and wellbeing
No full textThe growing unaffordability of housing in many high-income countries is pushing more people into temporary living situations. While housing is a recognised social determinant of health, less is known about the impact of housing insecurity and ‘hidden homelessness’, where families are not living on the street, but face repeated moves or protracted periods in temporary accommodation. This paper explores, from the perspective of parents and children, the impact of living in temporary accommodation on families’ health and wellbeing.
We undertook 38 interviews with parents and children across three geographical areas in England: South Yorkshire, the North West and London. Families were living (or had lived) in various forms of temporary accommodation including hotels, hostels, and bed and breakfast accommodation. Interviews took place in person, over the phone and online via video call. We utilised framework analysis to analyse our data.
Our analysis generated key themes focusing on: (i) the constant, cumulative stress associated with not knowing if, when and where stable accommodation might be secured, (ii) the spatial unsuitability of temporary accommodation for family life and (iii) the disconnection and disruption to social support, education and employment for families living in temporary accommodation.
This paper is the first to mobilise slow violence within a social determinants framework in understanding the multiple interacting ways in which temporary accommodation impacts on the health and wellbeing of families.</p
