This thesis focuses on the optimization and control of laser-driven plasma-based acceleration, whichinvolves the driver laser pulse, the accelerated electrons and the subsequent generation of x-rays.In laser wakefield acceleration (LWFA), a high-power laser pulse, typically with terawatt-levelpower, is focused tightly into a gas, reaching intensities on the order of > 1018 W/cm2. Even at the leadi
Idag lever allt fler människor under förhållanden som definieras som prekära. Även i avancerade välfärdssamhällen lyckas inte de traditionella trygghetssystemen erkänna och hantera de nya sociala risker som dessa grupper inom ”prekariatet” ställs inför. Bland dessa grupper finner vi migrantkvinnor med osäker rättslig ställning. Denna forskning undersöker hur aktörer i akademin och i civilsamhälletIn advanced welfare societies, traditional welfare programs are failing to recognize and respond to new social risks faced by groups in precarious life situations, including migrant women. This research explore how actors in academic and civil society settings recognize and frame the struggles of migrant women with precarious legal status, particularly in terms of gender-based violence (GBV) and a
Background: Parents face mental health challenges following their child's cancer diagnosis. However, it is unknown whether parental mental illness following a childhood cancer diagnosis influences the child's mortality.Patients and methods: Using several nationwide registers in Sweden, we identified children diagnosed with cancer between ages 0 to 14 from 2005 to 2016. Parental mental illness was
The sculpture, The Wolf Shall Dwell with the Lamb, is a contemporary adaptation of the prophecy of Isaiah (Chapter 11, Verse 6), installed as a suspended monument to world peace. At first glance, the figures of the wolf and lamb rest together, enveloped in cloth, as if frozen in a moment just before the public unveiling of the sculpture. Yet upon closer inspection, the fabric is revealed as insepa
The Viking Age (c. 800–c. 1050 ad) was characterised by a widespread rise in maritime mobility and interaction, as is made clear by an increasing range of evidence. However, this evidence provides limited information about the sailors and the sailing voyages that connected and transformed the Viking world. This paper presents an approach to reconstruct Viking Age maritime itineraries through the c
The prevalence of tattoos in western countries is about 20%. Tattoo ink may contain carcinogenic compounds. The aim of this study was to investigate if tattoo exposure is associated with an increased risk of cutaneous squamous cell carcinoma in individuals. In this population-based case-control study, 2857 cases aged 20 to 60 years, diagnosed between 2014 and 2017, were identified in the Swedish C
In this thesis, we investigate the random normal matrix model in which the eigenvalues correspond to the two-dimensional Coulomb gas at inverse temperature β = 2. The thesis consists of seven papers concerning differentaspects of the random normal matrix model. The main topics of the thesis are asymptotics of the correlationkernel, fluctuations of linear statistics, asymptotics of the partition fu
The building sector, as a major consumer of energy and resources, has been slow to adopt sustainability and digitalization compared to other sectors. This dissertation investigates how digital tools, particularly computational design (CD), can support the reuse of building parts within a circular economy framework, through design for disassembly and reuse-centred design (RCD) strategies. The resea
Purpose: Digitalization and circularity are core elements to achieve a sustainabledevelopment and call for innovation in the building sector. Although reusing building parts is recognized as a viable strategy, it requires adapted design approaches. Generative design (GD) could assist designers in elaborating suitable solutions using the existing building stock as well as in designing for future re
Background: Individualized cancer rehabilitation should be an integral part of cancer care. Contact nurses play a key role in identifying patient needs and coordinating evidence-based interventions to support rehabilitation. However, cancer rehabilitation remains marginal in current practice, as contact nurses face challenges due to the lack of systematic processes for assessment, intervention, an
Context. The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization at distances from the Solar System far greater than thermally equilibrated terrestrial exoplanets, offering observational opportunities for unique insights into the origin of secondary atmospheres and the near surface conditions of
In this paper we study the evolution of radiative fluxes, flux radii and observable dust masses in protoplanetary discs, in order to understand how these depend on the angular momentum budget and on the assumed heat sources. We use a model that includes the formation and viscous evolution of protoplanetary gas discs, together with the growth and radial drift of the dust component. We find that we
The radius distribution of close-in planets has been observed to have a bimodal distribution, with a dearth of planets around ∼1.5–2.0 R commonly referred to as the ‘radius valley’. The origin of the valley is normally attributed to mass-loss processes such as photoevaporation or core-powered mass loss. Recent work, however, has suggested that the radius valley may instead arise as a consequence o
PLATO (PLAnetary Transits and Oscillations of stars) is ESA’s M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to <2REarth) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations
Planets form and obtain their compositions from the leftover material present in protoplanetary disks of dust and gas surrounding young stars. The chemical make-up of a disk influences every aspect of planetary composition, including their overall chemical properties, volatile content, atmospheric composition and potential for habitability. This Review discusses our knowledge of the chemical and i
Icy dust particles emerge in star-forming clouds and are subsequently incorporated in protoplanetary disks, where they coagulate into larger pebbles up to millimeter in size. In the disk midplane, ices are shielded from UV radiation, but moderate levels of disk turbulence can lift small particles to the disk surface, where they can be altered, or destroyed. Nevertheless, studies of comets and mete
Light to the Nations is a work created by Yael Bartana which combines different media such as sculpture, VR, and video animation, as well as a learning center.It is a proposal about the attempts, dystopic and utopic, to save humanity in the face of a global catastrophe, whether man-made or caused by nature, which would extinguish any possibility of life on Earth. The work is influenced by post-apo
How can the strategic direction for an organization be supported and communicated if planning, and even strategies, are no longer sufficient options in the age of complexity? In this book it is argued that sense-making communication defines contemporary societies and organizations in a world where narratives and the ability to engage in strategic improvisation are crucial. In the book, new and old
Three channel video and sound installation, 7 min. In her work Overcoming the Future Yael Bartana continues her longstanding inquiry into the human capacity for hope –a prophetic emotion based on past experiences and a prime motor of the political imagination. It is based on Bartana’s interest in the 1920s as a time of intense political, ideological, and social upheavals alive with utopian vision
One channel video and sound installation, 11.35 min.In communities of the diaspora, music can be a powerful tool for collectively preserving memories. Along with storytelling, traditional languages, and dancing, songs can represent a living home for stateless nations.Commissioned by the Jewish Brazilian art space Casa do Povo, Yael Bartana's new work brings together two groups from two different d
