Regional motion correction for in vivo photoacoustic imaging in humans using interleaved ultrasound images

In translation from preclinical to clinical studies using photoacoustic imaging, motion artifacts represent a major issue. In this study the feasibility of an in-house algorithm, referred to as intensity phase tracking (IPT), for regional motion correction of in vivo human photoacoustic (PA) images was demonstrated. The algorithm converts intensity to phase-information and performs 2D phase-tracki

Spatially resolved spectroscopy across stellar surfaces : V. Observational prospects: Toward Earth-like exoplanet detection

Context. High-precision stellar analyses require hydrodynamic 3D modeling. Testing such models is feasible by retrieving spectral line shapes across stellar disks, using differential spectroscopy during exoplanet transits. Observations were presented in Papers I, II, and III, while Paper IV explored synthetic data at hyper-high spectral resolution for different classes of stars, identifying charac

Spatially resolved spectroscopy across stellar surfaces : IV. F, G, and K-stars: Synthetic 3D spectra at hyper-high resolution

Context. High-precision stellar analyses require hydrodynamic 3D modeling. Such models predict changes across stellar disks of spectral line shapes, asymmetries, and wavelength shifts. For testing models in stars other than the Sun, spatially resolved observations are feasible from differential spectroscopy during exoplanet transits, retrieving spectra of those stellar surface segments that succes

Stability assessment of p-i-n perovskite photovoltaic mini-modules utilizing different top metal electrodes

Long-term stability is one of the major challenges for p-i-n type perovskite solar modules (PSMs). Here, we demonstrate the fabrication of fully laser-patterned series interconnected p-i-n perovskite mini-modules, in which either single Cu or Ag layers are compared with Cu/Au metalbilayer top electrodes. According to the scanning electron microscopy measurements, we found that Cu or Ag top electro

Dijet resonance searches for dark matter mediators using the ATLAS detector

Dark matter is abundant in the universe, yet its composition and nature are unknown. If dark matter consists of new particles with nonzero interactions with Standard Model particles, it could be produced and detected or inferred by collider experiments. This thesis describes searches for dark matter models with new spin-1 force mediators coupling dark matter to quarks, using the ATLAS detector at

The transformation of the forest steppe in the lower Danube Plain of southeastern Europe : 6000 years of vegetation and land use dynamics

Forest steppes are dynamic ecosystems, highly susceptible to changes in climate, disturbances and land use. Here we examine the Holocene history of the European forest steppe ecotone in the lower Danube Plain to better understand its sensitivity to climate fluctuations, fire and human impact, and the timing of its transition into a cultural forest steppe. We used multi-proxy analyses (pollen, n-al

Is there evidence for the racialization of pharmaceutical regulation? : Systematic comparison of new drugs approved over five years in the USA and the EU

Recent decades have seen much interest in racial and ethnic differences in drug response. The most emblematic example is the heart drug BiDil, approved by the US Food and Drug Administration in 2005 for “self-identified blacks.” Previous social science research has explored this “racialization of pharmaceutical regulation” in the USA, and discussed its implications for the “pharmaceuticalization o

From the extraordinary to the everyday : Discourses on American quality serial television in Sweden’s leading newspapers and the breakthrough of streaming TV

This essay explores discourses on American quality serial television in Sweden’s leading newspapers, and how a gradual discursive repositioning of quality TV – from the extraordinary to the everyday – is linked to Swedish television’s transition into a screen culture increasingly dominated by commercial streaming services. The analysis of the newspaper material shows that the campaign to legitimat

Finns det ett samband mellan yrkesfiske och turism?

Det finns en uttalad politisk vilja att stödja det lokala fisket i Sverige. Ett skäl till detta är att levande fiskehamnar kan locka turister till kustnära samhällen. I denna studie analyserar vi kopplingen mellanyrkesfiske och antalet gästnätter på hotell, vandrarhem och stugbyar.* Vi finner att antalet gästnätter är högre i kustkommuner med mer yrkesfiske.* Vi finner däremot inte stöd för att yr

Computational modeling of mechanobiology in intact and healing rat Achilles tendon

Tendons fulfill an important musculoskeletal function by enabling energy-efficient force transmission between muscles and bones. The tendon is a collagen-rich connective tissue that adapts to mechanical loading through mechanobiological processes. The tendon contains a hierarchical collagen fiber structure that displays complex mechanical behaviour by storing and dissipating energy. Current unders

Förhöjd vardaglighet : Unga på landsbygden gör vardag

I avhandlingen skildras vardagslivet hos en grupp unga som bor på landsbygden. Medan vardagen i regel ses som grå och trist visar avhandlingen hur unga gör den till något särskilt, meningsfullt och roligt, hur de gör förhöjd vardaglighet. Genom att studera ungas vardagsliv med etnografiska metoder och teoretisk nyfikenhet når studien kunskap bortom de problembeskrivningar som vanligtvis skildrar sToday, the terms ‘young people’ and ‘rural Sweden’ are automatically associated with problems. Young people are associated with various worrying issues, such as mental illness, stress, pressure at school, or internet risk. Being young and living in a rural community is often regarded as especially problematic. Rural life is thought dull, and bracketed with isolation, lack of meaningful activities,

The physical and mental impact of surviving sepsis – a qualitative study of experiences and perceptions among a Swedish sample

Background: Sepsis is a critical illness with high morbidity and mortality rates. Each year, sepsis affects about 48.9 million people all over the world. This study aims to illuminate how sepsis survivors experience sepsis and the impact of sepsis, as well as the health-related quality of life thereafter. Methods: An interview study with eight sepsis survivors was carried out in Sweden with an ind

Stability of supported aerosol-generated nanoparticles in liquid media

The stability of nanoparticles and their supports are critical, but poorly understood, parameters for applications of such systems in liquid environments. Here we develop an approach to systematically investigate the stability of aerosol-generated nanoparticles after exposure to commonly used solvents using a combination of identical location-SEM and density/size analysis. We demonstrate that the

Falls After Stroke : A Follow-up after Ten Years in Lund Stroke Register

OBJECTIVES: To evaluate incidence of self-reported falls and associated factors in a ten-year perspective after stroke.METHODS: From a population-based cohort of first-ever stroke patients (n = 416) included in the Lund Stroke Register between March 1, 2001, and February 28, 2002, we performed a follow up of all 145 survivors ten years after stroke. We collected data on age, gender, main stroke ty

Antibodies against apoB100 peptide 210 inhibit atherosclerosis in apoE-/- mice

Atherosclerotic plaques are characterized by an accumulation and subsequent oxidation of LDL, resulting in adaptive immune responses against formed or exposed neoepitopes of the LDL particle. Autoantibodies against native p210, the 3136–3155 amino acid sequence of the LDL protein apolipoprotein B-100 (apoB100) are common in humans and have been associated with less severe atherosclerosis and decre

Methotrexate reduces circulating Th17 cells and impairs plasmablast and memory B cell expansions following pneumococcal conjugate immunization in RA patients

Methotrexate (MTX) impairs antibody response after pneumococcal vaccination. We aimed to investigate differences in phenotypes of circulating B and T cells after pneumococcal conjugate vaccine (PCV) in rheumatoid arthritis (RA) patients on MTX (MTX group), RA without disease-modifying drugs (0DMARD), and controls (HC). MTX group (n = 11), 0DMARD (n = 12) and HC (n = 13) were studied. Blood samples

Sediment Sampling and Analysis in Rönne å at Ängelholm

This report presents the results of sediment sampling in Rönne å (river) at Ängelholm, located in the north-western part of Scania, which is the southern-most province in Sweden. The sampling and subsequent grain-size analysis were performed primarily to verify hypotheses about main mechanisms controlling local scour at a number of sites where scour holes had been observed in the river during deta
