Generalized Cesàro Operators: Geometry of Spectra and Quasi-Nilpotency

For the class of Hardy spaces and standard weighted Bergman spaces of the unit disk, we prove that the spectrum of a generalized Cesàro operator Tg is unchanged if the symbol g is perturbed to g+h by an analytic function h inducing a quasi-nilpotent operator Th⁠, that is, spectrum of Th equals {0}⁠. We also show that any Tg operator that can be approximated in the operator norm by an operator Th w

A Fast Pixelated Thermal-Neutron Detector

This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden. The response of the detector scintillator, multi-anod

The bounty of the sea and long-run development

We document that a high level of natural productivity of the ocean - a rich bounty of the sea - has had a positive and persistent impact on economic development since pre-industrial times until today. In addition, we document that it is the bounty of the sea of the ancestors of current populations which drives the persistent effect, not geography per se. We argue that an explanation is that a rich

Those Who Stayed: Selection and Cultural Change during the Age of Mass Migration

This paper studies the cultural causes and consequences of mass emigration from Scandinavia in the 19th century. I test the hypothesis that people with individualistic traits were more likely to emigrate, because they faced lower costs of leaving established social networks behind. Data from population censuses and passenger lists confirm this hypothesis. Children who grew up in households with no

Svenska sändebud i revolutionens kaos

Recension av Anna Pavlenko & Per Enerud: Ett fruktansvärda skräckvälde råder i Ryssland. Ryska revolutionen i svensk diplomatisk rapportering 1917-1919

Diagnostic disagreement between clinical standard histopathological- and retrospective assessment of histopathology-based gastrointestinal graft-versus-host disease in children

Background: No previous paediatric study has evaluated the frequency of diagnostic disagreement between clinical standard histopathological assessment (CSHA) and retrospective, independent, histopathological assessment (RIHA) of gastrointestinal Graft-Versus-Host Disease (GI-GVHD). Methods: In a retrospective cohort study, based on gastrointestinal biopsies collected from allogeneic HSCT-treated c

Symptom occurrence and distress after heart transplantation—a nationwide cross-sectional cohort study

Experiencing symptoms after heart transplantation may hamper the heart recipient’s self-management which can lead to negative effects. We know little about symptom occurrence and distress after heart transplantation, especially in relation to sociodemographic variables. The aim of the study was to explore self-reported symptom occurrence and distress after heart transplantation and their relations

Tobacco smoking, snuff dipping and the risk of cutaneous squamous cell carcinoma : a nationwide cohort study in Sweden

We investigated whether tobacco use causes cutaneous squamous cell carcinoma (CSCC) in a large cohort study with complete and long-term follow-up. A total of 756 incident cases occurred in a cohort of 337,311 men during a 30-year follow-up period, but no association was found between any kind of smoking tobacco use and CSCC risk, nor any risk change with increasing dose, duration or time since smo

Primary care practitioners' diagnostic action when the patient may have cancer : an exploratory vignette study in 20 European countries

OBJECTIVES: Cancer survival rates vary widely between European countries, with differences in timeliness of diagnosis thought to be one key reason. There is little evidence on the way in which different healthcare systems influence primary care practitioners' (PCPs) referral decisions in patients who could have cancer.This study aimed to explore PCPs' diagnostic actions (whether or not they perfor

Reduced expression of C5a receptors on neutrophils from cord blood

AIM: To describe further functional deficiencies of neonatal neutrophils by measuring the expression of C5a receptors.METHODS: C5a uptake was measured using flow cytometry with fluorescein isothiocynate labelled recombinant C5a. The response of neutrophils to stimulation with C5a and fMLP was tested by measuring migration and exocytosis of myeloperoxidase and lactoferrin.RESULTS: C5a mean fluoresc

Admission glucose level was associated with increased short-term mortality and length-of-stay irrespective of diagnosis, treating medical specialty or concomitant laboratory values

Background: Glucose is a routine emergency sample. General guidelines for inpatient hyperglycemia are scarce, except in myocardial infarction, stroke, and perioperative/ICU. Previous studies found admission glucose associated with increased mortality in specific conditions. Scandinavian data, and for general patients, are scarcer. We investigated admission glucose levels, 30-day mortality, and len

Analysis of retinal structure and function in cone dystrophy with supernormal rod response

Purpose: To report the clinical and electrophysiological features of cone dystrophy with supernormal rod response (CDSRR). Methods: Retrospective cohort study of 15 unrelated patients (nine males and six females, median age 16, range 5–47 years) diagnosed with CDSRR by clinical examination, full-field electroretinography (ERG) and genetic testing. Observations: History, ophthalmic examination incl

Recent divergence in the contributions of tropical and boreal forests to the terrestrial carbon sink

Anthropogenic land use and land cover changes (LULCC) have a large impact on the global terrestrial carbon sink, but this effect is not well characterized according to biogeographical region. Here, using state-of-the-art Earth observation data and a dynamic global vegetation model, we estimate the impact of LULCC on the contribution of biomes to the terrestrial carbon sink between 1992 and 2015.
