Background: Accurate and internationally comparable human papillomavirus (HPV) DNA detection and typing services are essential for HPV vaccine research and surveillance. Objectives: This study assessed the proficiency of different HPV typing services offered routinely in laboratories worldwide. Study design: The HPV Laboratory Network (LabNet) has designed international proficiency panels that can
The synthesis aims to lay the foundation for an improved understanding of the biophysical influence of land-use and land-cover changes on regional climate and terrestrial ecosystem change in Sweden, and to outline a roadmap for developing tools that support the formulation of policies and decision-making by policymakers, taking these potentially significant effects into account. The additional inf
Large-scale photovoltaic solar farms envisioned over the Sahara desert can meet the world's energy demand while increasing regional rainfall and vegetation cover. However, adverse remote effects resulting from atmospheric teleconnections could offset such regional benefits. We use state-of-the-art Earth-system model simulations to evaluate the global impacts of Sahara solar farms. Our results indi
Field-based thermal infrared cameras provide surface temperature information at very high spatial and temporal resolution and could complement existing phenological camera and spectral sensor networks. Since temperature is one of the main drivers of ecosystem respiration (ER), field-based thermal cameras offer a new opportunity to model and upscale ER in unprecedented detail. We present such an ap
Popular Abstract in Swedish Avhandlingen består av fyra artiklar som behandlar olika aspekter av vattenvågor med vorticitet. Artikel I: Symmetry of steady periodic gravity water waves with vorticity. Vi bevisar att en fortskridande, periodisk, två-dimensionell, rotationell gravitationsvåg, med en ytprofil som är monoton mellan vågdalar och vågtoppar, måste vara symmetrisk kring vågtoppen, oavsAbstract: This thesis consists of four papers related to various aspects of water waves with vorticity. Paper I: Symmetry of steady periodic gravity water waves with vorticity. We prove that steady periodic two-dimensional rotational gravity water waves with a monotone surface profile between troughs and crests have to be symmetric about the crest, irrespective of the vorticity distribution wi
Scientists have deemed existing protected areas in European forests insufficient to halt and reverse biodiversity loss resulting from ongoing intensification of management. In Sweden, protected areas are therefore complemented with the so-called areas of high conservation value (AHCVs), that is, landscapes encompassing both protected and assumed biodiversity-valuable areas as well as surrounding l
This paper provides an overview of the Neurigona species found in Iran. During our studies in northern Iran four species of the genus Neurigona Róndani, 1856 have been collected, three of which for the first time in Iran: Neurigona helva Negrobov & Tsurikov, 1990, Neurigona pallida (Fallén, 1823) and Neurigona pseudolongipes Negrobov, 1987. One species, Neurigona persiana Pollet & Kazerani
The Arctic is warming rapidly, especially in winter, which is causing large-scale reductions in snow cover. Snow is one of the main controls on soil thermodynamics, and changes in its thickness and extent affect both permafrost thaw and soil biogeochemistry. Since soil respiration during the cold season potentially offsets carbon uptake during the growing season, it is essential to achieve a reali
Childhood stunting is a serious public health concern in Rwanda. Although stunting causes have been documented, we still lack a more in-depth understanding of their local factors at a more detailed geographic level. We cross-sectionally examined 615 height-for-age prevalence observations in the Northern Province of Rwanda, linked with their related covariates, to explore the spatial heterogeneity
The long-term carbon storage capacity of the boreal forest is under threat from the increasing frequency and intensity of wildfires. In addition to the direct carbon emissions during a fire, the burnt forest often turns into a net carbon emitter after fire, leading to large additional losses of carbon over several years. Understanding how quickly forests recover after a fire is therefore vital to
Meeting the Paris Agreement’s temperature goals requires limiting future carbon emissions, yet current policies make temporarily overshooting the 1.5°C target likely. The potential climate feedback from destabilizing peatlands, storing large amounts of carbon, remains poorly quantified. Using the reduced-complexity Earth System Model OSCAR with an integrated peat carbon module, we found that acros
Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments. This study examines WS by combining trends in pumping energy consumption and wate
In his comment (Kowalski 2023) on our recent publication (Heiskanen et al. 2022) where we present the Integrated Carbon Observation System (ICOS) research infrastructure, Andrew Kowalski introduces three important and, in our opinion, different potential issues in the definition, collection, and availability of field measurements made by the ICOS network, and he proposes possible solutions to thes
In this paper I propose an emancipation effect that may follow from the ‘reducing effect’ of frequency (Bybee 2006): if a reduced realization of an item gains in frequency, it will become conceptually independent from the full form. In a context of grammaticalization, I show that this is the case for the form gonna, which is becoming emancipated from its source form going to. I use corpus data of
Argonauts of industry: Knowledge gathering and technologies in use in Sweden’s industrial breakthroughIn this article we explore how knowledge transfer about industrial production and new technologies affected Sweden’s rapid industrialisation in the second half of the nineteenth century.

With the continuous increase of rapid urbanization and population growth, sustainable urban land-use planning is becoming a more complex and challenging task for urban planners and decision-makers. Multi-objective land-use allocation can be regarded as a complex spatial optimization problem that aims to achieve the possible trade-offs among multiple and conflicting objectives. This paper proposes
