The Forward Physics Facility : Sites, experiments, and physics potential
- 2022

Tidskriftsartikel (refereegranskat)abstract
- The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider during the High Luminosity era. Located along the beam collision axis and shielded from the interaction point by at least 100 m of concrete and rock, the FPF will house experiments that will detect particles outside the acceptance of the existing large LHC experiments and will observe rare and exotic processes in an extremely low-background environment. In this work, we summarize the current status of plans for the FPF, including recent progress in civil engineering in identifying promising sites for the FPF and the experiments currently envisioned to realize the FPF's physics potential. We then review the many Standard Model and new physics topics that will be advanced by the FPF, including searches for long-lived particles, probes of dark matter and dark sectors, high-statistics studies of TeV neutrinos of all three flavors, aspects of perturbative and non-perturbative QCD, and high-energy astroparticle physics.

Loss of the lupus autoantigen Ro52/Trim21 induces tissue inflammation and systemic autoimmunity by disregulating the IL-23-Th17 pathway
- 2009
-
Ingår i: Journal of Experimental Medicine. - : Rockefeller University Press. - 0022-1007 .- 1540-9538. ; 206:8, s. 1661-1671

Tidskriftsartikel (refereegranskat)abstract
- Ro52/Trim21 is targeted as an autoantigen in systemic lupus erythematosus and Sjögren's syndrome. Polymorphisms in the Ro52 gene have been linked to these autoimmune conditions, but the molecular mechanism by which Ro52 may promote development of systemic autoimmune diseases has not been explored. To address this issue, we generated Ro52-null mice (Ro52(-/-)), which appear phenotypically normal if left unmanipulated. However, Ro52(-/-) mice develop severe dermatitis extending from the site of tissue injury induced by ear tags. The affected mice further develop several signs of systemic lupus with hypergammaglobulinemia, autoantibodies to DNA, proteinuria, and kidney pathology. Ro52, which was recently identified as an E3 ligase, mediates ubiquitination of several members of the interferon regulatory factor (IRF) family, and the Ro52-deficient mice have an enhanced production of proinflammatory cytokines that are regulated by the IRF transcription factors, including cytokines involved in the Th17 pathway (interleukin [IL] 6, IL-12/IL-23p40, and IL-17). Loss of IL-23/IL-17 by genetic deletion of IL-23/p19 in the Ro52(-/-) mice conferred protection from skin disease and systemic autoimmunity. These data reveal that the lupus-associated Ro52 protein is an important negative regulator of proinflammatory cytokine production, and they provide a mechanism by which a defective Ro52 function can lead to tissue inflammation and systemic autoimmunity through the IL-23-Th17 pathway.

Konferensbidrag (refereegranskat)abstract
- The activities of the EUROfusion consortiums on the development of high quality nuclear data for fusion applications are presented. The activities, implemented in the Power Plant Physics and Technology (PPPT) programme of EUROfusion, include nuclear data evaluations for neutron and deuteron induced reactions and the production of related data libraries which satisfy the needs for nuclear analyses of the DEMO fusion power plant and the IFMIF-DONES neutron source. The activities are closely linked to the JEFF initiative of the NEA Data Bank. The evaluation work is complemented by extensive benchmark, sensitivity and uncertainty analyses to check the performance of the evaluated cross-section data and libraries against integral experiments.

Tidskriftsartikel (refereegranskat)abstract
- Double-differential production yields of light ions (p, d, t, (3)He, and alpha) from a thin silicon target induced by 175 MeV quasi mono-energetic neutrons were measured using the MEDLEY setup at the The Svedberg Laboratory (TSL) in Uppsala in order to benchmark evaluated nuclear data and nuclear reaction models. The MEDLEY is a conventional spectrometer system which consists of eight counter telescopes. Each telescope is composed of two silicon surface barrier detectors as the Delta E detectors and a CsI(Tl) scintillator as the E detector for particle identification. The telescopes are placed at angles from 20 degrees to 160 degrees in steps of 20 degrees. The measured double-differential yields of light ions are compared with PHITS calculations using the following nuclear reaction options: the high-energy nuclear data library (JENDL/HE-2007), the quantum molecular dynamics (QMD) model, and the intra-nuclear cascade (INC) model.

Changes, Activities and Bones : Intra-site analysis of the Pitted Ware Culture site Ajvide on the Baltic Sea island of Gotland
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this dissertation the structure, practices and evolution of a single Pitted Ware Culture site, Ajvide on Gotland, is explored and placed within the larger Pitted Ware Culture context. The site has been excavated over a period of 24 years, making it one of the most excavated Pitted Ware Culture sites in Sweden. Extensive archaeological and osteological material, burials, scattered human skeletal remains and faunal skeletal remains were discovered at Ajvide. Through the lens of practices identified by the means of these archaeological and osteological materials within different areas of Ajvide, the extensive remains can be untangled, creating a deeper insight to the Pitted Ware Culture on Gotland, Sweden and Åland. The osteological mass material has been analysed by studying species distribution, age, distribution of body parts, degree of bone fragmentation and more. It has thus been possible to provide an in-depth image of the handling of animal remains. This was achieved by applying GIS through the use of distribution maps as well as visual and statistical analysis. Seal hunting, fishing, the question of keeping and/or hunting domestic pigs/wild boars, the introduction of new species and rituals involving animals at Ajvide can all be studied throughout the 800 years of Middle Neolithic use of Ajvide. Combining the handling of animal remains with other prominent datasets, such as the documented features, dark areas and postholes, the archaeological data revealed a detailed timeline of practices and the impact of environmental events on those practices. Ajvide, and the practices identified there, can be placed within a greater context through comparative studies of other Pitted Ware Culture sites on Gotland, the Swedish mainland and Åland.
