In this paper we have investigated the dynamics of photo-generated charge carriers in a series of aerotaxy-grown GaAs nanowires (NWs) with different levels of Zn doping. Time-resolved photo-induced luminescence and transient absorption have been employed to investigate radiative (band edge transition) and non-radiative charge recombination processes, respectively. We find that the photo-luminescen
Recently we reported a method for estimating the spontaneous curvatures of lipids from temperature-dependent changes in the lattice parameter of inverse hexagonal liquid crystal phases of binary lipid mixtures. This method makes use of 1,2-dioleoyl-sn-glycerol-3-phosphoethanolamine (DOPE) as a host lipid, which preferentially forms an inverse hexagonal phase to which a guest lipid of unknown spont
Scattering of photons by phonons, or Brillouin scattering, enables manipulation and control of light and has led to revolutionary applications, from slow light to saser and cooling of micromechanical resonators. Recently, enhanced light and sound interaction has been demonstrated in waveguides. However, the design of the waveguide geometry tunes and alters the phonon and photon dispersion simultan
Introduction: Identifying factors that influence individuals' smoking behavior remains a huge public health concern. This study aimed to investigate changes in individuals' cigarette smoking while considering well-known smoking determinants, including social capital, its presence being postulated to reduce smoking. Methods: From British Household Panel Survey data, two baseline smoking cohorts wer
By identifying individuals with low peak bone mass (PBM) at young age, early targeted interventions to reduce future fracture risk could be possible. Peripheral quantitative computed tomography (pQCT) is in many ways superior to the gold standard dual-energy X-ray absorptiometry (DXA), as cortical and trabecular compartments as well as the volumetric density and bone structure can be examined sepa
Understanding electronic processes in organometal halide perovskites, flourishing photovoltaic, and emitting materials requires unraveling the origin of their electronic transitions. Light polarization studies can provide important information regarding transition dipole moment orientations. Investigating individual methylammonium lead triiodide perovskite nanocrystals enabled us to detect the pol
Background: Teamcare should, like all patient care, also contribute to evidence-based practice (EBP). Randomized controlled trials (RCTs) focusing on teamcare have been performed but no study has addressed its essentials. How far this EBP has progressed in different health aspects is generally established in systematic reviews of RCTs. Aim: The aim is to determine the essentials of teamcare includ
The Fano line shape arises from the interference of two excitation pathways to reach a continuum. Its generality has resulted in a tremendous success in explaining the line shapes of many one-dimensional spectroscopies - absorption, emission, scattering, conductance, photofragmentation - applied to very varied systems - atoms, molecules, semiconductors, and metals. Unraveling a spectroscopy into a
We demonstrate crack-free ZnO/GaN distributed Bragg reflectors (DBRs) grown by hybrid plasma-assisted molecular beam epitaxy using the same growth chamber for continuous growth of both ZnO and GaN without exposure to air. This is the first time these ZnO/GaN DBRs have been demonstrated. The Bragg reflectors consisted up to 20 periods as shown with cross-sectional transmission electron microscopy.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease that involves major remodelling of cells and tissue in the lung. There has been much focus on the inflammatory response, while less attention has been paid to structural changes and alterations of the extracellular matrix (ECM). In this review we revisit some of the latest findings on what is currently known about ECM a
Background: COPD is defined as partly irreversible airflow obstruction. The response pattern of bronchodilators has not been followed in advanced lung function parameters. Purpose: The aim of this study was to investigate bronchodilator response pattern in advanced lung function parameters in a continuous fashion along forced expiratory volume in 1 second (FEV1) percent predicted (%p) in COPD pati
The value of a Quality-Adjusted Life-Year (QALY) and the Value of a Statistical Injury (VSI) are important measures within health economics and transport economics. Several studies have therefore estimated people’s WTP for these estimates, but most results show problems with scale insensitivity. The Chained Approach (CA) is a method developed to reduce this problem. The objective of this study was
Solar energy is the most abundant renewable energy source available. Conversion of light into electricity and chemical energy are the two major paths for solar energy conversion. Nanostructured organic and hybrid materials are being explored for applications in photovoltaic solar energy conversion, as well as photocatalysis for solar fuel generation. Light harvesting, energy transport, charge phot
Objectives The objectives of this study were to examine the prevalence of penicillin-susceptible bacteremic Staphylococcus aureus in the Malmö area in 2014, to re-evaluate the phenotypic methods of penicillinase detection on these isolates, and to investigate the clonal distribution of penicillin-susceptible isolates. Methods All non-redundant S. aureus from blood in the Malmö catchment area in so
The aim of the present study is to investigate associations between parental separation/divorce during childhood, and self-reported psychological health, adjusting for social capital, social support, civil status and economic stress in childhood. A cross-sectional public health survey was conducted in the autumn of 2012 in Scania, southern Sweden, with a postal questionnaire with 28,029 participan
The advent of tyrosine kinase inhibitors (TKI) into the management of patients with chronic myeloid leukemia (CML) has profoundly improved prognosis. Survival of responders is approaching that of the general population but lifelong treatment is still recommended. In several trials, TKI treatment has been stopped successfully in approximately half of the patients with deep molecular response. This
Purpose: Substance use disorders and problematic substance use are common problems in adolescence and young adulthood. Brief personalized feedback has been suggested for treatment of alcohol and drug problems and poor mental health. This repeated measurement randomized controlled trial examines the effect of an interactive voice response (IVR) system for assessing stress, depression, anxiety and s
