Klima is a carbon-backed cryptocurrency running as a decentralized autonomous organization (DAO). In 2021, it had accumulated 9 million metric tons of digital carbon credits and reached a market value of more than US$1 billion. In 2023, its treasury stored twice as many carbon credits, but its spot price was a tiny fraction compared to 2021. Building on prior scholarship at the intersection of car
Maria Arnelid, Petter Falk, Desirée Enlund, ErickaJohnson, Sara Mörtsell, Olof Sundin, Fredrik StiernstedtRecent global events, including the COVID-19 pandemic, wars and migration streams, have highlighted the promise of digital infrastructures while also showcasing how dependent we are on digital systems for accessing welfare services such as healthcare, social services and education, as well as for accessing public service media. Notably, in the context of welfare provision, different people and soc
In this work, we present an actors-to-hardware design flow where applications are described as networks of actors and compiled to hardware. Specifically, we use the CAL actor language to describe these applications. CAL has previously been used to specify applications such as the MPEG-RVC decoder and is well suited for compilation to hardware. A key limitation of CAL is that the applications descr
PurposeThis study investigates the anchoring effect in property valuation among students from different educational backgrounds, aiming to determine whether an engineering education mitigates cognitive bias compared to a social science education.Design/methodology/approachAn experimental design was implemented during the final examinations in property valuation courses at two Swedish universities.
The paper is a commentary on the tables in George Peurbach՚s Tabulae Eclypsium and presents their mathematical background with many of the tables analyzed and recalculated. These tables, based on the Alfonsine tradition, made possible more accurate and less tedious calculations of the circumstances of solar and lunar eclipses and were in many respects an improvement over previous similar tables. T
Lung transplantation (LTx) remains the only curative treatment for patients with end-stage lung disease, yet long-term outcomes remain inferior to those of other solid organ transplantations, with a 5-year survival below 70%. Major contributors to this limited outcome include primary graft dysfunction (PGD), the leading cause of early mortality, chronic lung allograft dysfunction (CLAD), and low u
Exposure to engineered nanomaterials (ENMs) at the workplace can adversely affect human health via inhalation. Occupational exposure limits (OELs) for specific ENMs remain scarce due to a lack of nano-specific data and consensus on the most appropriate dose metric for exposure assessment. In 2022, recommendations were provided on how to derive Health-based Nano Reference Values (HNRVs) for differe
Background: The incidence, aetiology, and outcome of unplanned intensive care unit admission after elective colon cancer surgery remain unclear. This study investigated the incidence of, and factors associated with, unplanned intensive care unit admission following elective colon cancer resection in Sweden. Methods: This nationwide retrospective registry study included adult patients undergoing el
Background: Research on the primary care management of back pain in children and young people (CYP) is scarce. Sociodemographic factors may influence presentation and management, potentially contributing to disparities in care and outcomes. This study aimed to describe the management of back pain in CYP and examine associations with sociodemographic characteristics. Methods: Data were extracted fr
Psychedelic experiences have been associated with improved quality of life, but many studies rely on samples of enthusiasts, raising concerns about selection bias. This study examined whether self-reported quality-of-life impact differed between a convenience sample of psychedelic enthusiasts and a general population sample recruited through Prolific, and whether sample differences persisted after
Von Economo neurons (VENs) have been reported to be vulnerable to neurodegeneration in frontotemporal dementia (FTD), particularly the behavioral variant (bvFTD), but these findings have not been systematically assessed across independent brain banks. We conducted a meta-analysis of neuropathological studies measuring VEN density in the anterior cingulate cortex or frontoinsular cortex in FTD usin
An innovative coaxial dual-swirl combustor was developed to address the challenges of combustion instability and NOx emissions inherent to ammonia combustion. The combustor employs an inner swirler supplying a premixed ammonia/air stream and an outer swirler generating a premixed methane/air flame that stabilizes the inner ammonia flame. Combined large-eddy simulations (LES) and planar laser-induc
This thesis is devoted to the study of different aspects of groups acting on rooted trees and their applications.First, we focus on the Hausdorff dimension of groups acting on rooted trees. We develop new tools that lead to the solution of several well-known open problems in the subject due to Abért-Virág, Bartholdi, Grigorchuk, Klopsch and Shalev among others.Secondly, we study many aspects of thThis thesis is devoted to the study of different aspects of groups acting on rooted trees and their applications.First, we focus on the Hausdorff dimension of groups acting on rooted trees.

Long-distance migrants face numerous challenges during their migration, with the spring migration timing being particularly important, as early arrival at the breeding grounds often enhances breeding success. Both innate and environmental factors influence migration timing in birds, and the earlier arrival of males than females is common among songbirds breeding in temperate zones. The great reed
In the future, buildings need to be energy resilient to tackle the energy crisis. This article introduces a concept for classifying the energy resilience of buildings in extreme cold and warm weather in Finland during blackouts. It presents a techno-economic comparison between an old and a new single-family building integrated with photovoltaic (PV) systems and batteries, analyzing their resilienc
Transient concurrent flame spread over solid surfaces involves multiple interacting physical processes, where simplified modelling with effective parameter identification is still challenging. This study presents a modelling framework that combines scaling-based formulation with Bayesian parameter inference to quantitatively capture the transient behaviors of concurrent flame spread. Experimental
