- Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of 30 000 men and women aged between 50 and 64 years. The information obtained will be used to improve risk prediction of cardiopulmonary diseases and optimize the ability to study disease mechanisms. A comprehensive pilot study in 1111 individuals, which was completed in 2012, demonstrated the feasibility and financial and ethical consequences of SCAPIS. Recruitment to the national, multicentre study has recently started.

- Objective: This paper aims at studying the influence of single-nucleotide polymorphisms (SNPs) on cancer risk, tumor recurrence, and survival in head and neck (H&N) cancer patients. Methods: A total of 45 SNPs in 41 genes were investigated. A total of 174 Caucasian H&N cancer patients and 245 healthy blood donors were enrolled in the study. Results: Ten SNPs were associated with H&N cancer risk, but the identified SNPs differed among males and females. Some of the SNPs were related to immune response genes. The immune response gene SNPs were also related to survival. In particular, we noted that the tumor necrosis factor alpha (TNFα) rs1800629 could have an influence on cancer risk, tumor recurrence as well as survival. Conclusion: Genetic variation of the TNFα rs1800629 might be useful as a biomarker in clinical decision-making since it was found to be related to cancer risk, tumor recurrence, and survival of H&N cancer patients.

Med de nya svenska klimatmålen i sikte : Gapanalys samt strategier och förutsättningar för att nå etappmålen 2030 med utblick mot 2045
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Under våren 2017 presenterade Naturvårdsverket scenarier för hur växthusgasutsläppen i Sverige skulle kunna utvecklas till 2035. Sedan Naturvårdsverket presenterade scenarierna har ett nytt klimatpolitiskt ramverk för Sverige beslutats av riksdagen med nya klimatmål till 2030, 2040 och 2045. Regeringen har även presenterat ett antal nya styrmedel i budgetpropositionen.Naturvårdsverket ska inom miljömålssystemet löpande och strategiskt analysera och utvärdera styrmedel och åtgärder. Naturvårdsverket har mellan maj och november 2017 gjort en första uppföljning mot de nya klimatmålen. I denna rapport presenteras hur beslutade och planerade styrmedel kan komma att falla ut givet olika antagande. En översiktlig analys av styrmedel görs också.Arbetsgruppens sammansättning har varierat över tid. Sammantaget har följande personer på Naturvårdsverket deltagit i arbetsgruppen: Tea Alopaeus (projektledare), Björn Boström, Mats Björsell, Martin Boije, Joanna Dickinson, Dag Henning, Daniel Engström Stenson, Eva Jernbäcker (projektledare till september), Julien Morel, Miriam Münnich Vass, Karl-Anders Stigzelius, Ulrika Svensson, Per Wollin.Stockholm 29 november 2017Björn RisingerGeneraldirektör

Reliable hp finite element computations of scattering resonances in nano optics
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Eigenfrequencies are commonly studied in wave propagation problems, as they are important in the analysis of closed cavities such as a microwave oven. For open systems, energy leaks into infinity and therefore scattering resonances are used instead of eigenfrequencies. An interesting application where resonances take an important place is in whispering gallery mode resonators.The objective of the thesis is the reliable and accurate approximation of scattering resonances using high order finite element methods. The discussion focuses on the electromagnetic scattering resonances in metal-dielectric nano-structures using a Drude-Lorentz model for the description of the material properties. A scattering resonance pair satisfies a reduced wave equationand an outgoing wave condition. In this thesis, the outgoing wave condition is replaced by a Dirichlet-to-Neumann map, or a Perfectly Matched Layer. For electromagnetic waves and for acoustic waves, the reduced wave equation is discretized with finite elements. As a result, the scattering resonance problem is transformed into a nonlinear eigenvalue problem.In addition to the correct approximation of the true resonances, a large number of numerical solutions that are unrelated to the physical problem are also computed in the solution process. A new method based on a volume integral equation is developed to remove these false solutions.The main results of the thesis are a novel method for removing false solutions of the physical problem, efficient solutions of non-linear eigenvalue problems, and a new a-priori based refinement strategy for high order finite element methods. The overall material in the thesis translates into a reliable and accurate method to compute scattering resonances in physics and engineering.
