Using Micro-Scale and Solid Material Data for Modelling Heat Transfer in Stone Wool Composites Under Heat Exposures
Modelling capabilities have drastically improved in the last decade. However, in most of the cases the fire response of building elements is predicted by fitting input material properties to the models in order to match test data. This paper presents models developed to predict the unexposed side temperature of stone wool layered composites with stainless steel or gypsum claddings exposed to sever
A localization theorem for the planar coulomb gas in an external field
We examine a two-dimensional Coulomb gas consisting of n identical repelling point charges at an arbitrary inverse temperature β, subjected to a suitable external field. We prove that the gas is effectively localized to a small neighbourhood of the droplet – the support of the equilibrium measure determined by the external field. More precisely, we prove that the distance between the droplet and t
Close relationships in Parkinson´s disease patients with device-aided therapy
Objectives: Deep brain stimulation, continuous subcutaneous apomorphine infusion, and levodopa–carbidopa intestinal gel infusion, together called device-aided therapies (DAT), are introduced when oral and transdermal pharmacotherapy are not enough for a satisfactory control of Parkinson's disease (PD) symptoms. Solid relationships are central to an individual's well-being, but the impact of close
A widespread mechanism in ectomycorrhizal fungi to access nitrogen from mineral-associated proteins
A large fraction of nitrogen (N) in forest soils is present in mineral-associated proteinaceous compounds. The strong association between proteins and minerals limits microbial accessibility to this source, which is a relatively stable reservoir of soil N. We have shown that the ectomycorrhizal (ECM) fungus Paxillus involutus can acquire N from iron oxide-associated proteins. Using tightly control
Panel data measures of price discovery
This paper considers disaggregated price data that are observed not only for multiple markets over extended periods of time, but also for a large number of assets. The previous literature has argued that in such data rich environments, which arise frequently in applied work, the analysis of price discovery can be made more precise by accounting for the panel structure of the data. Moreover, since
Exosome-Functionalized Ceramic Bone Substitute Promotes Critical-Sized Bone Defect Repair in Rats
Ceramic biomaterials are promising alternatives to bone autografts. However, limited bioactivity affects their performance. Therefore, bioactive molecules and cells are often added to enhance their performance. Exosomes have emerged as cell-secreted vesicles, delivering proteins, lipids, and nucleic acids in a paracrine/endocrine fashion. We studied two complementary aspects required for exosome a
A simplified decision rule to rule out deep vein thrombosis using clinical assessment and D-dimer
Background: Current clinical decision rules to exclude deep vein thrombosis (DVT) are underused partly because of their complexity. A simplified rule that can be easily applied would be more appealing to use in clinical practice. Methods: We used individual patient data from prospective diagnostic studies of patients suspected of DVT to develop a new clinical decision rule. The primary outcome was
The Incidental Parameters Problem in Testing for Remaining Cross-Section Correlation
In this article, we consider the properties of the Pesaran CD test for cross-section correlation when applied to residuals obtained from panel data models with many estimated parameters. We show that the presence of period-specific parameters leads the CD test statistic to diverge as the time dimension of the sample grows. This result holds even if cross-section dependence is correctly accounted f
Cytokines in gingival crevicular fluid in elderly rheumatoid arthritis patients in a population-based cross-sectional study : RANTES was associated with periodontitis
Objective: We studied cytokines in gingival crevicular fluid (GCF) in a cross-sectional population-based cohort of rheumatoid arthritis (RA) patients ≥61 years of age with and without a diagnosis of periodontitis. Background data: Earlier studies on cytokines in GCF in RA patients have not given clear results. Methods: In a population-based cross-sectional study of patients ≥61 years of age, 233 R
Physical exercise is associated with beneficial bone mineral density and body composition in young adults with childhood-onset inflammatory bowel disease
Background: Patients with inflammatory bowel disease (IBD) have an increased risk of compromised bone mineral density (BMD) and body composition. There are limited data on the physical exercise (PE) habits of patients with childhood-onset IBD and on the associations between PE and BMD and body composition. Patients and methods: In total, 72 young adults with childhood-onset IBD and 1341 normative
The politics of Myanmar’s agrarian transformation
Myanmar is in a dangerous and uncertain moment following the military coup on 1 February 2021. The articles in this Special Forum provide timely contextual analysis. Written before the coup, the articles delve into the politics of agrarian transformation in the context of (what was then) an ongoing (but fragile) opening up of political space. This introduction outlines three themes that connect th
Rasch Analysis of the Norwegian Version of the Occupational Balance Questionnaire in a Sample of Occupational Therapy Students
Background. Recently, the Occupational Balance Questionnaire developed in Sweden was translated into Norwegian. No studies to date have examined the measurement properties of the Norwegian version of this questionnaire. Aim. The study is aimed at examining the psychometric properties of the Norwegian version of the Occupational Balance Questionnaire, the OBQ11-N. Methods. Along with sociodemograph
Mapping microscale PM2.5 distribution on walkable roads in a high-density city
Monitoring pollution of PM2.5 on walkable roads is important for resident health in high-density cities. Due to the spatiotemporal resolution limitations of Aerosol Optical Depth (AOD) observation, fixed-point monitoring, or traditional mobile measurement instruments, the microscale PM2.5 distribution in the walking environment cannot be fully estimated at the fine scale. In this study, by the int
Comparative barrier membrane degradation over time : Pericardium versus dermal membranes
Objective: The effectiveness of GBR procedures for the reconstruction of periodontal defects has been well documented. The objective of this investigation was to evaluate the degradation kinetics and biocompatibility of two resorbable collagen membranes in conjunction with a bovine xenograft material. Materials and Methods: Lower premolars and first molars were extracted from 18 male Yucatan minip
FBAdLibrarian and Pykognition: open science tools for the collection and emotion detection of images in Facebook political ads with computer vision
We present a methodological workflow using two open science tools that we developed. The first, FBAdLibrian, collects images from the Facebook Ad Library. The second, Pykognition, simplifies facial and emotion detection in images using computer vision. We provide a methodological workflow for using these tools and apply them to a case study of the 2020 US primary elections. We find that unique ima

Biogas recovery for sustainable cities: A critical review of enhancement techniques and key local conditions for implementation
There is great potential to apply energy recovery from municipal wastewater treatment plants (WWTP) to achieve better energy efficiency and greenhouse gas emissions abatement. However, in most of the wastewater treatment plants that produce biogas through sludge digestion, there is no thermal energy recovery or electricity generation, and the biogas is flared and wasted, particularly in developing
