Machine learning techniques for predictive maintenance of building services: a comprehensive review and research outlook
Get PDFPurpose: Predictive maintenance in buildings is crucial for minimising unplanned downtime and extending lifespan of building components, yet its implementation remains complex. Machine learning (ML) offers a transformative approach by enabling systematic predictions and automation. The purpose of this study is to analyse the interrelationship between ML techniques and predictive maintenance of building services, identifying key research trends and future directions. Design/methodology/approach: A bibliographic analysis was conducted on 118 journal articles using VOSviewer to examine co-authorship and co-occurrence patterns. The key themes generated were then explored semi-systematically, focusing on the most frequently used ML techniques and predictive maintenance applications. Findings: The results reveal a strong relationship between ML and predictive maintenance, with increasing research interest post-2021. Co-occurrence analysis highlights the evolution of research themes, shifting from conventional ML models to advanced techniques such as digital twins and lifelong learning with deep generative replay modelling. Among the most frequently applied ML techniques, Extreme Gradient Boosting, Artificial Neural Networks and Deep Neural Networks have demonstrated the best predictive performance in fault diagnostics and system optimisation. Practical implications: The findings advocate for stronger interdisciplinary collaborations among researchers, institutions and industries to bridge the gap between research advancements and real-world implementation in facilities management and building life cycle. Originality/value: This study provides a comprehensive examination of research trends, highlighting underexplored ML applications in building services predictive maintenance.</p

The Calcium Signalling Profile of the Inner Blood–Retinal Barrier in Diabetic Retinopathy
Get PDFDiabetic retinopathy is a sight-threatening complication of diabetes mellitus, affecting millions of people worldwide. From a vascular perspective, diabetic retinopathy compromises the structure and function of the blood–retinal barrier, leading to aberrant angiogenesis and vascular leakage, with consequent loss of vision. This review will delve into the vascular abnormalities caused by diabetic retinopathy in the inner blood–retinal barrier, focusing primarily on retinal endothelial cells. It will then discuss how calcium signalling regulates inner blood–retina barrier function and dysfunction, how calcium channels contribute to the development of diabetic retinopathy, and how studying the components of the calcium toolkit may identify new therapeutic targets
The Ex Vivo Organ Culture of Bone and Cartilage
No full textThe ex vivo organ culture of bone provides many of the advantages of both the whole organism and isolated cell strategies. Moreover, it can deliver valuable insight into the network of processes fundamental to bone and cartilage biology and thus provide an invaluable tool in pursuit of understanding skeletal health and disease. Through maintaining the bone and/or cartilage cells in their native environment, this model system provides the investigator with a powerful experimental protocol to address specific facets of skeletal growth and development. In this chapter, we outline the basic protocols and possible readouts of organ culture models to replicate; (a) linear bone growth (murine metatarsal culture model), (b) articular cartilage and subchondral bone metabolism (murine femoral head culture model), (c) bone response to mechanical stimulation (bovine trabecular core culture model), and (d) bone resorption and formation (murine calvaria culture model)
Associations between podoconiosis and pedogenic factors globally – a systematic review.
Get PDFBackgroundPodoconiosis is a non-infectious neglected tropical disease that causes progressive swelling of the lower limbs in an estimated 4 million people globally. Podoconiosis has been associated with prolonged exposure to certain soils, however no specific causative component has been identified. We conducted a systematic review of articles to investigate links between podoconiosis and mineral, geochemical and climate factors affecting soil genesis (pedogenesis).Methodology/principal findingsA systematic search was conducted across five electronic databases: Embase, Global Health, Medline, GeoRef and Web of Science. Searches were from database inception to January 2024. Primary quantitative research from any region was included, qualitative studies and those not in English were excluded. The AXIS tool was used to assess study quality and risk of bias. Twenty-seven studies were included and narrative synthesis was used to interpret data from tissue samples, soil samples, and remote sensed bedrock and pedogenic factors. Nine studies found a correlation between podoconiosis occurrence and regions with underlying alkalic volcanic bedrock, and six linked pedogenic factors (altitude and rainfall) with disease occurrence. Several studies linked specific soil mineralogy and geochemistry with endemic regions, including an abundance of phyllosilicate clay minerals, quartz, and trace elements, notably iron, beryllium and zirconium.ConclusionsThis systematic review is the first to be conducted on the literature linking pedogenic factors with podoconiosis globally. Study quality was low for some of the earlier (1970s) studies. Several soil mineralogical and geological variables were linked with podoconiosis prevalence, particularly kaolinite, smectite, micas, quartz, iron oxides and trace elements. However, it remains unclear whether these are covariates or direct contributors to the pathogenesis of the disease and what the role of other peculiarities of soils (complex mineral-organic or material-climate combined factors) might be. Studies on the enrichment of minerals and elements during pedogenesis should be prioritised in future research
Breadcrumbing by a dating partner, perceived social support, and paranoia
No full textBreadcrumbing is an abusive dating behavior that involves sending non-comital signals to another person and feigning interest in them, despite having no intention of taking the relationship forward. Exposure to breadcrumbing has been found to be harmful for mental health but there is no research into its relationship with more severe psychopathology, such as paranoid ideation. This study examines the relationship between exposure to breadcrumbing and paranoid ideation through the mediation of perceived social support, while controlling for the effects of age and sex. An Advanced Mediation Generalized Linear Model was built based on cross-sectional correlational survey data from 544 participants in the United Kingdom. Exposure to breadcrumbing was indirectly associated with paranoid ideation through the mediation of perceived social support. Sex impacted perceived social support, with men reporting lower perceived social support. Age impacted paranoid ideation, with younger participants reporting higher paranoid ideation. The results suggest that more frequent exposure to breadcrumbing from current or past dating partners may result in a perception of lower social support from others which in turn increases the risk of paranoid ideation. Psychological interventions should focus on enabling clients to develop and retain connections with others to access social support in the face of breadcrumbing
Ditchling Fable Book
No full textThis book is essentially to show illustrations of Ditchling through the fables of Aesop together with other drawings that depict locations within the Sussex village. The fables are told by several writers from the past, from William Caxton’s in 1484 (the first illustrated publication of the fables in England); Odo of Cheriton in the 13th Century; Aphra Behn and Roger L’Estrange writing in the 17th century; Samuel Croxall in the 18th century; Thomas James, George Fyler Townsend, Henry Thomas Riley and Joseph Jacobs in the 19th century; and Vernon Jones in the 20th century. John Vernon Lord (born 1939 in Glossop, Derbyshire) is an author, illustrator and educator. He studied at Salford School of Art and at the Central School of Arts and Crafts in London.
