COVID-19 vaccine effectiveness against severe disease from the Omicron BA.1 and BA.2 subvariants: surveillance results from southern Sweden, December 2021 to March 2022

We compared vaccine effectiveness (VE) against severe COVID-19 during calendar periods from December 2021 to March 2022 when Omicron BA.1 and BA.2, respectively, were the dominating virus variants in Scania county, Sweden. We used continuous density case-control sampling matched for sex and age, and with further adjustment for differences in comorbidities and prior infection. VE remained relativel

Institutional Interplay in Global Environmental Governance : lessons learned and future research

Over the past decades, the growing proliferation of international institutions governing the global environment has impelled institutional interplay as a result of functional and normative overlap across multiple regimes. This article synthesizes primary contributions made in research on institutional interplay over the past twenty years, with particular focus on publications with International En

Association of Annual N-Terminal Pro-Brain Natriuretic Peptide Measurements with Clinical Events in Patients with Asymptomatic Nonsevere Aortic Stenosis : A Post Hoc Substudy of the SEAS Trial

Importance: Recent studies have questioned the presumed low-risk status of patients with asymptomatic nonsevere aortic stenosis (AS). Whether annual N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements are useful for risk assessment is unknown. Objective: To assess the association of annual NT-proBNP measurements with clinical outcomes in patients with nonsevere AS. Design, Setting, a

Fractionation of Nanoparticle Matter in Red Wines Using Asymmetrical Flow Field-Flow Fractionation

The particle matter of wine is mainly composed of wine colloids and macromolecules. The present work develops a methodology using asymmetrical flow field-flow fractionation coupled with multi-angle light scattering, differential refractive index detector, and ultraviolet detector (AsFlFFF−MALS−dRI−UV) for the fractionation and determination of the molar mass, the hydrodynamic radius, and the appar

A model of an integrated hydrothermal liquefaction, gasification and Fischer-Tropsch synthesis process for converting lignocellulosic forest residues into hydrocarbons

The aim of this work was to develop a model of an integrated biomass-to-liquid process, consisting of hydrothermal liquefaction, evaporation, gasification and Fischer-Tropsch synthesis, using lignocellulosic forest residues as feedstock to produce hydrocarbons suitable for upgrade into drop-in biofuels. The energy, mass and carbon efficiencies that were achieved were 35%, 20% and 32%, respectively

Effects of pulse chirp on laser-driven proton acceleration

Optimisation and reproducibility of beams of protons accelerated from laser-solid interactions require accurate control of a wide set of variables, concerning both the laser pulse and the target. Among the former ones, the chirp and temporal shape of the pulse reaching the experimental area may vary because of spectral phase modulations acquired along the laser system and beam transport. Here, we

The ABCDE of supply chain visibility : A systematic literature review and framework

Supply chain visibility is a concept that is gaining increasing attention. Increasing levels of visibility in the supply chain is considered beneficial in many respects. A systematic literature review identified 47 empirical research papers from international scientific journals. Two main findings emerged from the content analysis. First, the perspectives provided in the extant literature can be g

A moving-boundary model of reactive settling in wastewater treatment. Part 1 : Governing equations

Reactive settling is the process of sedimentation of small solid particles in a fluid with simultaneous reactions between the components of the solid and liquid phases. This process is important in sequencing batch reactors (SBRs) in wastewater treatment plants. In that application the particles are biomass (bacteria; activated sludge) and the liquid contains substrates (nitrogen, phosphorus) to b

A technocratic road to spatial justice? : The standard as planning knowledge and the making of postwar Sweden’s welfare landscapes

This article analyses the politics of spatial justice in the knowledge-making practices of planning expertise in postwar Sweden. The paper traces the genealogy of ‘standards’ in modern Swedish planning, arguing that this was a fundamental form of planning knowledge which came to articulate a ‘universalist’ politics of justice. Standards were constructed as a way to measure and make complex calcula

The causal effect of education and cognitive performance on risk for suicide attempt : A combined instrumental variable and co-relative approach in a Swedish national cohort

Background: The aim of this study was to clarify the possible causal associations between education phenotypes and non-fatal suicide attempts. In particular, we evaluated the roles of academic achievement (school grades), cognitive performance (IQ), and educational attainment (education level). Methods: Based on longitudinal Swedish registry data, we included 2,335,763 individuals (48.7% female) w

Characterisation and cross-amplification of sex-specific genetic markers in Australasian Egerniinae lizards and their implications for understanding the evolution of sex determination and social complexity

Sex is a pervasive factor that underpins functional phenotypic variation across a range of traits. Although sex can usually be distinguished morphologically, in some species this is not possible. The development of genetic markers for sex identification is, thus, key if we are to incorporate sex into an understanding of ecological or evolutionary process. Here we develop genetic markers for the id

Can differential fatty acid composition help migrating birds to limit oxidative lipid damage?

During migratory endurance flights, which are energetically very demanding, migrants have to deal with prolonged elevated generation of reactive oxygen species (ROS). To limit the damaging actions that ROS have on lipids and proteins, migrating birds are known to upregulate their antioxidant defence system. However, there may be additional ways to limit oxidative damage incurred from flying. Migra

Untangling the controversy on Ce3+luminescence in LaAlO3crystals

Aluminum perovskites represent an important group of promising scintillation materials with excellent proportionality and energy resolution, but due to difficulties in crystal growth not much attention has been paid to them. We studied a Ce-doped LaAlO3lanthanum-aluminum perovskite (LaAP) because of its easy crystal growth facilitated by the large La3+cations in the matrix. Moreover, recent observ

Traveling waves and transverse instability for the fractional Kadomtsev–Petviashvili equation

Of concern are traveling wave solutions for the fractional Kadomtsev–Petviashvili (fKP) equation. The existence of periodically modulated solitary wave solutions is proved by dimension-breaking bifurcation. Moreover, the line solitary wave solutions and their transverse (in)stability are discussed. Analogous to the classical Kadmomtsev–Petviashvili (KP) equation, the fKP equation comes in two vers

The diagnostic utility of DNA copy number analysis of core needle biopsies from soft tissue and bone tumors

Morphologic and immunohistochemical analysis of preoperative core needle biopsies (CNB) is important in the management of patients with soft tissue and bone tumors (STBTs). Most SBTB subtypes have more or less extensive DNA copy number aberrations (CNA), potentially providing useful diagnostic information. To evaluate the technical feasibility of single nucleotide polymorphism (SNP) array analysis
