A concept of germ graphs and the M-function formalism are employed to construct large families of isospectral and isoscattering graphs. This approach represents a complete departure from the original approach pioneered by Sunada, where isospectral graphs are obtained as quotients of a certain large symmetric graph. Using the M-function formalism and the symmetries of the graph itself we construct
An emissions barrier was used in a premises due to complaints about the indoor air quality (IAQ) as a result of emissions from the building in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood and volatile organic compounds (VOCs), mainly 2-ethylhexanol, from polyvinyl chloride (PVC) flooring and the glue used to paste the f
In applied psychology, ontological assumptions are rarely subjected to scrutiny. Yet ontological positionings will affect all aspects of a research undertaking. Assumptions about what is real—and what is not—will affect conceptualization, study design, and analytical focus. In the investigation of social influence, failure to engage with ontological positionings has resulted in a default ontology
This study analyzes how violent conflict influences taxation in a poor, conflict-affected country, Burkina Faso. We use a unique, large, and representative panel dataset on tax collection of firms between 2015 and 2022 and geographically match these data with indicators of violent conflict at the municipal level. We find that firms pay a lower amount of tax in areas affected by violence. We also fThis study analyzes how violent conflict influences taxation in a poor, conflict-affected country, Burkina Faso.

Solar photo-voltaic (PV) and wind offer to bring both clean energy and clean water to remote regions and peri-urban areas in the world, outside the conventional electric grids. One out of seven people has no electric power available that would bring light to the home, cook the food, pump to access water and purify or re-use it. Off-grid systems are scalable and can be designed to any size, from ho
Additive manufacturing (AM) is revolutionizing industrial production by enabling the fabrication of complex, customized components with reduced material waste. However, the scheduling of AM machines presents significant challenges in terms of optimizing both time-related performance and energy consumption. This paper introduces a novel multi-objective mixed-integer linear programming (MILP) model
Aims: To examine the separate associations of glycemic control and chronic kidney disease with hospitalization days over one year in patients with type 2 diabetes (T2D). Materials and methods: A cross-sectional study using retrospective data on T2D patients in Region Halland, Sweden, during 2020. Data from the Region Halland database included hospitalizations, emergency visits, primary care encoun
This chapter examines the enduring presence of pre-Christian, Pagan religious elements in Baltic folklore—the related but distinct folk traditions of Lithuania and Latvia—and the purposes these remnants of Baltic Paganism serve as expressions of ethnic and/or national identity. Particular attention is paid to a genre of folk songs known as dainasin Latvia and dainos in Lithuania, solstice celebrat
The aim of the paper is to show how Malmö Yllefabrik (MYA)(Malmö Woolen Factory) and its management contributed tobuilding an infrastructure in Malmö and Furulund in the late19th and early 20th centuries.The water situation was a constant reminder. The city councilin Malmö criticized the Woolen factory and other factories forpolluting the canal. At the same time, MYA had problems withdirty and cal
BACKGROUND: CDEUSSA is a Specific Support Action project from the Sixth Framework Programme Priority of the European Union (EU). Its aim is to bring together basic and applied research in the area of coeliac disease (CD). This paper reviews the main issues that are a result of the CDEUSSA initiative.AIM: To identify the major issues in need of investigation in the areas of clinical aspects, treatm
Bayesian optimization is a widely used method for optimizing expensive black-box functions, with Expected Improvement being one of the most commonly used acquisition functions. In contrast, information-theoretic acquisition functions aim to reduce uncertainty about the function’s optimum and are often considered fundamentally distinct from EI. In this work, we challenge this prevailing perspective
Background: Surgery in select individuals with inflammatory bowel disease (IBD) may obviate the need for future IBD-related treatment. Aims: To characterise individuals who remain treatment-free during the first 5 years after initial IBD-related surgery. Methods: We performed a nationwide cohort study using the Swedish National Patient Register and the ESPRESSO histopathology to identify individua
Open and shared government data and services offer an instrument for achieving innovation, interoperability, and transparency in public services but require relevant competency, resources, and culture to realise, something that the public sector actors often lack. In this case study, we exemplify how these challenges to data sharing may be tackled through horizontal coordination in the case of Tra
Introduction. The fourth edition of the Transatlantic Orthopedic Surgery Webinar 2022 took place on December 12th, 2022. The main theme of the webinar was the treatment of crouch gait in children with cerebral palsy (CP). Speakers from Australia, Canada, China, Germany, India, Poland, Spain, Sweden, Turkey, the United Kingdom, and the United States participated. Results. The first general session
Learning urban region embeddings has substantially advanced urban analysis, but their typical focus on individual cities leads to disparate embedding spaces, hindering cross-city knowledge transfer and the reuse of downstream task predictors. To tackle this issue, we present Consistency Region Embedding (CoRE), a unified framework integrating region embedding learning with crosscity latent space a
Tomography technology is not usual when investigating drilled asphalt cores properties. Currently, there is no internationally recognised standard tomography method for asphalt pavements. Tomography provides, however, a non-destructive alternative to traditional, usually destructive, testing of drilled cores. Furthermore, tomography offers possibilities, which traditional laboratory analyses do no
This article is concerned with the tenure track (TT) model, which has become increasingly used to extend the period of early career academics’ probation from one to five years across the EU. This article focuses on the TT in Trinity College Dublin (TCD), the oldest and most prestigious university in Ireland, one where gender equality has been embedded more consistently and where the pace of change
Introduction: The optimal timing for distal radial fracture fixation remains controversial. Most previous studies have dichotomized timing into early or delayed categories, potentially obscuring the true effect of delay. This study investigated surgical timing as a continuous variable to determine its influence on radiographic alignment. Methods: In a retrospective multicentre cohort study, we rev
Generalized anxiety disorder (GAD) is a severe and prevalent disorder among older adults. Cognitive behaviour therapy (CBT) is recommended treatment for GAD, but older adults benefit less than younger peers. Physical exercise has been suggested to improve treatment efficacy. We aimed to determine the efficacy of augmenting CBT with physical exercise for older adults with GAD. This randomised contr
