This thesis is composed of five papers, which all attempt to optimise calculations of scattering amplitudes in high-energy-physics collisions. These scattering amplitudes are a key part of theoretical predictions for particle-physics experiments like the Large Hadron Collider at CERN. The first four papers are the main topic of the thesis, and describe a novel method called chirality flow. Chirali
A method is presented for the determination of complex-valued compression and shear elastic moduli of polymers for ultrasound applications. The resulting values, which are scarcely reported in the literature, are found with uncertainties typically around 1% (real part) and 6% (imaginary part). The method involves a setup consisting of a cm-radius, mm-thick polymer ring glued concentrically to a di
Green infrastructure (GI) is increasingly used in policymaking to promote biodiversity and enhance ecosystem services through the protection, creation, restoration and connection of natural and man-made green areas. The EU Commission adopted in 2013, the concept as a strategy. When member states apply the policy, it is translated into specific bureaucratic and political systems, creating different
OBJECTIVE: Treatment adherence is suggested to be associated with greater improvement in patient outcomes. Despite the growing use of digital therapeutics in osteoarthritis management, there is limited evidence of person-level factors influencing adherence to these interventions in real-world settings. We aimed to determine the relative importance of factors influencing adherence to a digital self
BACKGROUND: The EAT-Lancet Commission proposed a globally environmentally sustainable dietary pattern featuring mainly plant-based foods in 2019. However, evidence on this dietary pattern in preventing coronary events is minimal.OBJECTIVE: We aimed to examine the association between the EAT-Lancet diet and risk of coronary events.METHODS: The Malmö Diet and Cancer cohort study (recruited between 1
With an increase in international migration, it is becoming significant to examine the function of religious organizations to present a philanthropic model in which religious membership is not perceived as a source of social visibility and access to social resources based on religious affiliation. Due to the cultural diversity of the migrant community, it is important to explore the role of religi
Much has been written about the risks posed by artificial intelligence (AI). This article is interested not only in what is known about these risks, but what remains unknown and how that unknowing is and should be approached. By reviewing and expanding on the scientific literature, it explores how social knowledge contributes to the understanding of AI and its regulatory challenges. The analysis i
Organic colloids are an important part of dissolved organic matter (DOM) yet many of their properties remain elusive. The main aims of this study were to assess how the colloidal properties of DOM extracted with water from an organic boreal soil horizon varied with the extraction protocol, and thereby provide insight into the nature of the DOM colloids and develop a mechanistic understanding of ho
We re-examine the importance of instruction time for student achievement on international assessments. We successfully replicate the positive effect of weekly instruction time in the seminal paper by Lavy (Economic Journal, 125, F397-F424) in a narrow sense. Extending the analysis to other international assessments, we find effects that are consistently smaller in magnitude. We provide evidence th
While wild pollinators play a key role in global food production, their assessment is currently missing from the most commonly used environmental impact assessment method, Life Cycle Assessment (LCA). This is mainly due to constraints in data availability and compatibility with LCA inventories. To target this gap, relative pollinator abundance estimates were obtained with the use of a Delphi asses
This article is opened by explaining a specific type of hate speech: Holocaust denial. I will establish that Holocaust denial is a form of hate speech. The article is concerned with the expression of this idea by educators. I make some constructive distinctions that will help in crystallizing our treatment of teachers who are Holocaust deniers. Should we allow Holocaust deniers to teach in schools
In this paper, we compare two approaches to numerically approximate the solution of second-order Gurtin–Pipkin type of integro-differential equations. Both methods are based on a high-order Discontinous Galerkin approximation in space and the numerical inverse Laplace transform. In the first approach, we use functional calculus and the inverse Laplace transform to represent the solution. The spect
The prevalence of obesity has reached pandemic proportions, and now approximately 25% of adults in Westernized countries have obesity. Recognized as a major health concern, obesity is associated with multiple comorbidities, particularly cardiometabolic disorders. In this Review, we present obesity as an evolutionarily novel condition, summarize the epidemiological evidence on its detrimental cardi
Technical Analysis to Inform the Trigger Design for Adaptive Safety Nets in Malawi 2023 has been prepared by the Finance, Competitiveness & Innovation Global Practice’s Crisis, and Disaster Risk Finance team in collaboration with Tetra Tech, who acted as technical advisors for the World Bank. Funding and expertise were provided by the Disaster Protection Program (funded by the UK) and from the
The capacitive biosensor technology can be utilized for the analytical detection of a variety of different compounds. By employing the electrical double-layer principle, it is possible to detect very low concentrations of the target analyte due the methods inherent high sensitivity. This affinity-based capacitive biosensor is a powerful tool also for the analytical detection of low molecular weigh
The aim of this study is to estimate and compare soil erosion, in the Mount Elgon region, eastern Uganda, during the last decade. Possible trends and changes in erosion are linked to precipitation/climate change as well as changes in land cover. Two different versions of the Revised Universal Soil loss Equation RUSLE. are implemented and compared, one using slope length and the other using flow ac
Agricultural intensification and extreme weather events can represent considerable stress to soil microorganisms and their functions by influencing the key players behind the degradation of soil organic matter. A better understanding of the diversity and abundance of microbial functional genes that predict the functional potential of soils, can link the microbial communities to their key ecosystem
