Semiconductor nanowires (NW) have been of interest to optoelectronics research for several decades due to the unique optical effects resulting from their geometry. Today, NWs are fabricated from a wide range of materials, ranging from Si to III-Vs and emerging materials like metal-halide perovskites (MHPs). Among NW devices, single NW devices are of special interest because they offer both a usefu
This study analyses how the standard of living for different social groups changed when Sweden developed from an agricultural to an industrial society and when the first steps towards a modern welfare society were taken. As a measure of living standards, we use the ability to overcome short-term economic stress caused by high food prices. We use individual-level longitudinal data from 1813 to 1967
Objectives This study aims to investigate (1) the microbial community composition by work characteristics and (2) the association between microbial genera level and inflammatory markers among recycling workers. Methods In this cross-sectional study, inhalable dust was collected with personal samplers from 49 production (86 samples) and 10 administrative workers (15 samples). Four groups of micro-o
Confinement of reactants within nanoscale spaces of low-dimensional materials has been shown to provide reorientation of strained reactants or stabilization of unstable reactants for synthesis of molecules and tuning of chemical reactivity. While few studies have reported chemistry within zero-dimensional pores and one-dimensional nanotubes, organic reactions in confined spaces between two-dimensi
We investigate the use of a highly scalable intervention to help individuals achieve their physical activity goals: self-funded commitment contracts. Using a randomised experiment, we compare the effect of soft (non-incentivised) and hard (incentivised) contracts among 1629 members of a gym in Stockholm, Sweden. We find a significant positive impact of being offered a hard contract on monthly visi
Thrombosis in myeloproliferative neoplasms (MPNs) is an important clinical problem, and risk-stratified management is essential. To identify the clinical characteristics of thrombosis in patients with MPNs, a nationwide multi-institutional retrospective analysis (JSH-MPN-R18) was conducted. The aim of the present study was to perform a sub-analysis of JSH-MPN-R18 findings to clarify the predictive
Objective: Occupational exposure to welding fumes is linked to a higher risk of cardiovascular disease; however, the threshold exposure level is unknown. Here, we aimed to identify changes in proteins associated with cardiovascular disease in relation to exposure to welding fumes. Methods: Data were obtained from two timepoints six years apart for 338 non-smoking men (171 welders, 167 controls); o
This thesis describes the work done on two open access microcavities that aims at detecting single rare-earth ions for quantum information applications. The initial microcavity faced mechanical instability due to its geometry, which limited robust design possibilities due to the 25 mm diameter space of the helium bath cryostat. A Purcell enhancement of 2.2 was realized for nanoparticles at 2.1 K,
Objective We investigated associations between bioaerosol exposures and work-shift changes in lung function and inflammatory markers among recycling workers. Methods Inhalable dust was measured with personal samplers and analyzed for endotoxin, bacteria, and fungi (incubated at 25 °C and 37 °C) levels. Lung function (FEV1, FVC) was measured before and after work-shifts and serum concentrations of
Aim: To analyse the association between bone turnover markers and bone mass in children and young adults. Methods: This descriptive study followed 132 children (68 boys/64 girls) from Malmö, Sweden, as controls in a school-based intervention study (2000–2017). Height, weight, Tanner stage and bone mass were measured annually from ages 8 to 15 years, with follow-ups at 19 and 23 years of age. Serum
Nanoscale systems coupled to superconducting circuits offer a platform to study a variety of research questions ranging from more fundamental investigations on the quantum nature of light interacting with matter to more application-oriented ones such as quantum computing and communication. These hybrid systems have thus gained a great deal of attention in the community in the recent years and have
We theoretically investigate elementary excitations of dipolar quantum gases across the superfluid to supersolid phase transition in a toroidal trap. We show how decoupled first sound, second sound, and Higgs modes emerge by following their origin from superfluid modes across the transition. The structure of these excitations reveals the interplay between crystal and superfluid oscillations. Our r
Objectives: This study aimed to clinically validate the six-gene prognostic molecular clinical risk score (MCRS) for the prediction of aggressive prostate cancer in diagnostic biopsy tissue. Methods: MCRS was evaluated in prostate biopsy tissue from a Swedish cohort of men with prostate cancer (UPCA, n = 100). The primary outcome of adverse pathology and secondary outcomes of high primary Gleason
This article uses a new database of 1,891 probate inventories from rural southern Sweden to investigate the development of rural households’ productive capacity from the late 1600s to the 1860s. Both labourers and farmers improved their material living standards – as measured by the contents of probate inventories – but the labouring households’ ownership of means of production decreased over timeThis article uses a new database of 1,891 probate inventories from rural southern Sweden to investigate the development of rural households’ productive capacity from the late 1600s to the 1860s.

Peptides constitute alternative molecules for the treatment of infections caused by bacteria, viruses, fungi, and protozoa. However, their therapeutic effectiveness is often limited by enzymatic degradation, chemical and physical instability, and toxicity toward healthy human cells. To improve their pharmacokinetic (PK) and pharmacodynamic (PD) profiles, novel routes of administration are being ex
Complex forms of quantum entanglement can arise in two qualitatively different ways: either between many qubits or between two particles with higher-than-qubit dimension. While both the many-qubit frontier and the high-dimension frontier are well established, state-of-the-art quantum technology is becoming increasingly able to create and manipulate entangled states that simultaneously feature many
Understanding the nature of the photoexcitation and ultrafast charge dynamics pathways in organic halide perovskite nanocubes and their aggregation into superlattices is key for potential applications as tunable light emitters, photon-harvesting materials, and light-amplification systems. In this work, we apply two-dimensional coherent electronic spectroscopy (2DES) to track in real time the forma
