Circular business models in Japan : Analysis of circular business transformation through an institutional approach

The circular economy is becoming a globalised phenomenon, but the regional emergence of circular business models differs significantly. By adopting a circular business institutionalisation perspective which bridges theory on institutional work and “ecologies of business models” we study the emergence of circular business models in Japan, a region with recent circular policy and business commitment

Beware of diffusion models for synthesizing medical images—a comparison with GANs in terms of memorizing brain MRI and chest x-ray images

Diffusion models were initially developed for text-to-image generation and are now being utilized to generate high quality synthetic images. Preceded by generative adversarial networks (GANs), diffusion models have shown impressive results using various evaluation metrics. However, commonly used metrics such as Frechet inception distance and inception score are not suitable for determining whether

3D Quantitative MRI : A Fast and Reliable Method for Ventricular Volumetry

Purpose: Volumetry of cerebral ventricles is a far more sensitive measure for shunt-induced reduction of ventricular size than traditional 2-dimensional (2D) measures, such as Evans index. However, available ventricle segmentation methods are time-consuming, resulting in limited use in clinical practice. Quantitative MRI (qMRI) obtains objective measurements of physical tissue properties, enabling

Impacts of Spartina alterniflora invasion on coastal carbon cycling within a native Phragmites australis-dominated wetland

Despite its significance for climate adaptation, the impact of non-native Spartina alterniflora on coastal blue carbon cycling remains unclear. While it is generally reported that S. alterniflora invasion increases the soil organic carbon (SOC) stock along China's coastlines from tropical to subtropical climate zones, some cases, such as the Jiuduansha wetland in the Yangtze River estuary, show a

Irans agenda för att påverka omvärlden

The Islamist regime in Tehran is increasingly striving to influence, threaten, and spy on Swedish citizens. Influence operations now target not only Swedish-Iranians but also Swedes with no ties to Iran.

Cytopenias in Autoimmune Liver Diseases - A Review

Autoimmune liver diseases (AiLDs), including autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC), are immune-mediated conditions associated with significant hepatic and systemic manifestations. Among these, cytopenias-defined as reductions in blood cell counts affecting single or multiple lineages-represent a clinically important, though often un

Precise measurement of nuclear interaction cross sections towards neutron-skin determination with R3B

The R3B (Reactions with Relativistic Radioactive Beams) experiment as a major instrument of the NUSTAR collaboration for the research facility FAIR in Darmstadt is designed for kinematically complete studies of reactions with high-energy radioactive beams. Part of the broad physics program of R3B is to constrain the asymmetry term in the nuclear equation-of-state and hence improve the description

Lender-Borrower Stock Return Dependencies in Credit Networks: Evidence from Syndicated Loan Deals

We study the impact of credit networks on the interconnectedness between lenders' and borrowers' stock returns using syndicated loan data. We correct for biases from confounding factors and find significant stock return dependencies between small banks and large borrower firms with high default risk. Our analysis shows that portfolios of lender stocks, sorted based on signals from borrowers' retur

Embedded cluster approach for accurate electronic structure calculations of 229Th :CaF2

Building on recent advances of the embedded cluster approach combined with multiconfigurational theory, this work investigates the electronic states in thorium-doped CaF2 crystals. Th:CaF2 is established as a promising material for solid-state nuclear clocks, which utilize the laser-Accessible isomeric state in thorium-229. By comparing simulated absorption spectra of a library of defect configura

Aedas R&D : global practices of computational design

This paper gives an overview of the approach of working methods at the Aedas R&D Computational Design and Research [CDR] Group. It first contextualizes research in architectural practice and tries to propose an explanation for the difficulties in implementing it; then explains the evolution of the groups' computing approach from bespoke to heuristic sets of lightweight applications. It conclud

Simulation heuristics for urban design

Designing simulations for urban design not only requires explicit performance criteria of planning standards but a synthesis of implicit design objectives, that we will call 'purpose rules', with computational approaches. The former would at most lead to automation of the existing planning processes for speed and evaluation, the latter to an understanding of perceived urban qualities and their eff

Suburbs and power : configuration, direct and symbolic presence, absence, and power in the Swedish Suburb Gottsunda

One aspect of how cities are arranged and configured, from structures of communication networks to land division, programme distribution, and location of functions, monuments, and other urban objects is directly related to questions of power and representation. While sometimes more explicitly discussed regarding buildings or historical cities, as by Thomas A Markus and Kim Dovey, it is a present i
