Three-dimensional dynamics of a fermionic Mott wedding-cake in clean and disordered optical lattices

Non-equilibrium quantum phenomena are ubiquitous in nature. Yet, theoretical predictions on the real-time dynamics of many-body quantum systems remain formidably challenging, especially for high dimensions, strong interactions or disordered samples. Here we consider a notable paradigm of strongly correlated Fermi systems, the Mott phase of the Hubbard model, in a setup resembling ultracold-gases e

The release of a pheromonotropic neuropeptide, PBAN, in the turnip moth Agrotis segetum, exhibits a circadian rhythm

In the female turnip moth, Agrotis segetum, a pheromone biosynthesis activating neuropeptide (PBAN) stimulates sex pheromone biosynthesis which exhibits a daily rhythm. Here we show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the endogenous rhythm in sex pheromone biosynthesis. This conclusion is drawn as the observed daily rhythm in PBA

Vibrationally resolved resonant inelastic soft X-ray scattering spectra of free molecules

The brilliance of modern synchrotron radiation sources and capabilities of new instrumentation facilitate molecular resonant inelastic soft X-ray scattering with high spectral quality. Especially, energy resolution of vibrational fine structure allows for a detailed analysis, providing information about the dynamic coupling between nuclear and electronic degrees of freedom. After a brief historica

Giant, level-dependent g factors in InSb nanowire quantum dots.

We report on magnetotransport measurements on InSb nanowire quantum dots. The measurements show that the quantum levels of the InSb quantum dots have giant g factors, with absolute values up to approximately 70, the largest value ever reported for semiconductor quantum dots. We also observe that the values of these g factors are quantum level dependent and can differ strongly between different qua

Immunogenetics of Childhood Type 1 Diabetes in Immigrant Patients in Sweden. Migration Studies on Type 1 Diabetes

Popular Abstract in Swedish Syfte Syftet med denna avhandling var att undersöka om barn födda i Sverige till invandrare (icke-Svenskar) hade en ökad risk för typ 1 diabetes (T1D) och om immunogenetiska markörer för T1D (HLA och icke-HLA genetiska faktorer samt ö-cellsantikroppar) skiljde sig från svenska T1D barn (Svenskar). Målsättningen var också att analysera ärftliga förutsättningar (T1D och TThis thesis examined whether the offspring of immigrants (non-Swedes) to Sweden are at increased risk of Type 1 Diabetes (T1D) when they are born or live in Sweden. It also evaluated if their T1D and T2D-related genes differed from Swedish patients and whether this genetic heritage determined the types and existence of islet autoantibodies at time of diagnosis and affected the classification of di

Long-term changes in vegetation and soil chemistry in a calcareous and sandy semi-natural grassland

Calcicole plant species are vulnerable to acidification and fertilization, caused by deposition and changes in land use, since they are adapted to nutrient-poor calcareous conditions. In this study we used vegetation data (vascular plants, bryophytes and lichens) from 1964 and 1985 and stored soil samples from 1966 to investigate long-term soil chemistry and vegetation changes in a semi-natural, s

Dietary intakes of retinol, beta-carotene, vitamin D and vitamin E in the European Prospective Investigation into Cancer and Nutrition cohort

Objectives: To describe the intake of the fat-soluble nutrients retinol, beta-carotene, vitamin E and vitamin D and their food sources among 27 redefined centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Between 1995 and 2000, 36 034 subjects (age range: 35-74 years) completed a single standardized 24-h dietary recall u

Childhood overweight and obesity conceived by Child Health Care nurses: a qualitative study.

Background: Registered Sick Children's Nurses and District Nurses employed at Child Health Care centres are in a position to help prevent childhood overweight and obesity. Prevention of this challenging public health threat could be improved through having a better understanding of how this group of nurses perceives childhood obesity. The aim of this study was to elucidate the conceptions of child

Sensitivity of the carbon cycle in the Arctic to climate change

The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and human/cultural systems that may be irreversible on century time scales and have the potential to cause rapid changes in the earth system. The response of the carbon cycle of the Arctic to changes in climate is a major issue of global concern, yet there has not been a comprehensive review of the status of th

Morphometric Differences between the Medial and Lateral Meniscus in Healthy Men - A Three-Dimensional Analysis Using Magnetic Resonance Imaging

The objective of this work was to characterize tibial plateau coverage and morphometric differences of the medial (MM) and lateral meniscus (LM) in a male reference cohort using three-dimensional imaging. Coronal multiplanar reconstructions of a sagittal double-echo steady state with water excitation magnetic resonance sequence (slice thickness: 1.5 mm, and in-plane resolution: 0.37 x 0.70 mm) wer

Spin-polarized (001) surface states of the topological crystalline insulator Pb0.73Sn0.27Se

We study the nature of (001) surface states in Pb0.73Sn0.27Se in the newly discovered topological-crystalline-insulator (TCI) phase as well as the corresponding topologically trivial state above the band-gap-inversion temperature. Our calculations predict not only metallic surface states with a nontrivial chiral spin structure for the TCI case, but also nonmetallic (gapped) surface states with non

Data-Rich Multivariable Control of Heavy-Duty Engines

Popular Abstract in Swedish See attachment in related materialThe combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. More sophisticated engine instrumentation with additional degrees of freedom has been added to the engine de

Prosocial norms in the classroom: The role of self-regulation in following norms of giving

Children who are prosocial in elementary school tend to have higher academic achievement and experience greater acceptance by their peers in adolescence. Despite this positive influence on educational outcomes, it is still unclear why some children are more prosocial than others in school. The current study investigates a possible link between following a prosocial norm and self-regulation. We tes

Volatility of Organic Aerosol: Evaporation of Ammonium Sulfate/Succinic Acid Aqueous Solution Droplets

Condensation and evaporation modify the properties and effects of atmospheric aerosol particles. We studied the evaporation of aqueous succinic acid and succinic acid/ammonium sulfate droplets to obtain insights on the effect of ammonium sulfate on the gas/particle partitioning of atmospheric organic acids. Droplet evaporation in a laminar flow tube was measured in a Tandem Differential Mobility A

The History, Development, and Realisation of Medical Radiation Physics Education in Sweden

This paper describes the history of Swedish medical radiation physics education and gives details of the core curriculum of today’s 5-year specialised medical radiation physicist programme, which fulfils the need to educate clinical physicists with versatile basic knowledge and skills who are well prepared for professional life in all sub-areas of medical radiation physics and radiation protection

Phase Behavior in Suspensions of Highly Charged Colloids.

Attractive interactions between like-charged aggregates (macromolecules, colloidal particles, or micelles) in solution due to electrostatic correlation effects are revisited. The associated phenomenon of phase separation in a colloidal solution of highly charged particles is directly observed in Monte Carlo simulations. We start with a simple, yet instructive, description of polarization effects i

Output feedback distributed model predictive control with inherent robustness properties

We consider robust output feedback distributed model predictive control (DMPC). The proposed controller is based on the results in [8] in which nominal stability and feasibility was proven for a DMPC-formulation without terminal constraint set or terminal cost in the optimization. We extend these results to show robust stability under state feedback as well as output feedback when dynamics and mea
