The Swedish forestry model: intensifying production for sustainability

Sweden is often seen as a frontrunner when it comes to sustainability. For example, it has the highest share of renewable energy in the EU and is known for its thorough recycling and waste separation. Sweden is sparsely populated and 70% of its land area is covered by forests. Over the last century, the volume of yearly timber harvests has doubled, but despite this remarkable productivity increase

On the Extended Chen Distribution: Development, Properties, Characterizations and Applications

In this paper, a flexible model called extended Chen (EC) distribution is derived from the generalized Burr-Hatke differential equation and nexus between the exponential and gamma variables. The EC distribution is also derived from compounding mixture of the generalized Chen and gamma distributions. The EC distribution is very flexible and its hazard rate function accommodates various shapes such

Psychometric properties of the Persian version of the overall anxiety severity and impairment scale (OASIS)

Objectives: This study was conducted to assess the psychometric properties of the Persian version of the overall anxiety severity and impairment scale (OASIS), a measure designed to evaluate the severity and functional impairments associated with clinical and subsyndromal anxiety.Methods: Using a descriptive-analytic framework, first, the OASIS was translated into Persian according to the forward-

Functional brain response to emotional musical stimuli in depression, using INLA approach for approximate Bayesian inference

Introduction: One of the vital skills which has an impact on emotional health and well-being is the regulation of emotions. In recent years, the neural basis of this process has been considered widely. One of the powerful tools for eliciting and regulating emotion is music. The Anterior Cingulate Cortex (ACC) is part of the emotional neural circuitry involved in Major Depressive Disorder (MDD). Th

Society Inhaled. Social Epidemiology of COPD

Chronic Obstructive Pulmonary Disease (COPD) is a common disease that in its advanced stages is a life-limiting condition and a leading cause of death globally. This thesis aims at increasing the understanding of the socioeconomic disparities that exist both for COPD and its major risk factor, tobacco smoking. A related aim is to advance the theory and epidemiological methods used to evaluate equi

Avoidable deaths in Sweden, 1997–2018: temporal trend and the contribution to the gender gap in life expectancy

Background: Avoidable mortality is considered as a potential indicator of the influences of public health policies and healthcare quality on population health. This study aimed to examine the trend in avoidable mortality and its influence on rising life expectancy (LE) and declining gender gap in LE (GGLE) in Sweden. Methods: We extracted data on causes of death by age, sex, and year from nationa

Efficient, automated and robust pollen analysis using deep learning

Pollen analysis is an important tool in many fields, including pollination ecology, paleoclimatology, paleoecology, honey quality control, and even medicine and forensics. However, labour‐intensive manual pollen analysis often constrains the number of samples processed or the number of pollen analysed per sample. Thus, there is a desire to develop reliable, high‐throughput, automated systems. We p

Derivation and utility of an Aβ-PET pathology accumulation index to estimate Aβ load

OBJECTIVE: To evaluate a novel β-amyloid (Aβ)-PET-based quantitative measure (Aβ accumulation index [Aβ index]), including the assessment of its ability to discriminate between participants based on Aβ status using visual read, CSF Aβ42/Aβ40, and post-mortem neuritic plaque burden as standards of truth. METHODS: One thousand one hundred twenty-one participants (with and without cognitive impairmen

Large Extracellular Vesicle Characterization and Association with Circulating Tumor Cells in Metastatic Castrate Resistant Prostate Cancer

Liquid biopsies hold potential as minimally invasive sources of tumor biomarkers for diagnosis, prognosis, therapy prediction or disease monitoring. We present an approach for parallel single-object identification of circulating tumor cells (CTCs) and tumor-derived large extracellular vesicles (LEVs) based on automated high-resolution immunofluorescence followed by downstream multiplexed protein p

A finite element implementation of the stress gradient theory

In this contribution, a finite element implementation of the stress gradient theory is proposed. The implementation relies on a reformulation of the governing set of partial differential equations in terms of one primary tensor-valued field variable of third order, the so-called generalised displacement field. Whereas the volumetric part of the generalised displacement field is closely related to

Heading variations resolve the heading-direction ambiguity in vertical-beam radar observations of insect migration

Vertical-beam entomological radars provide precise measurements of the body alignment of individual overflying insects but are unable to distinguish which of the two axial directions the insect is heading towards. Insects migrating at altitude typically show common alignment, although with a broad spread. We show here that when observations from multiple individual insects are available, and the i

Information, switching costs, and consumer choice: Evidence from two randomised field experiments in Swedish primary health care

Consumer choice policies may improve the matching of consumers and providers, and may spur competition over quality dimensions relevant to consumers. However, the gains from choice may fail to materialise in markets characterised by information frictions and switching costs. We use two large-scale randomised field experiments in primary health care to examine if individuals reconsider their provid

2020 update on the clinical validity of cerebrospinal fluid amyloid, tau, and phospho-tau as biomarkers for Alzheimer’s disease in the context of a structured 5-phase development framework

Purpose: In the last decade, the research community has focused on defining reliable biomarkers for the early detection of Alzheimer’s disease (AD) pathology. In 2017, the Geneva AD Biomarker Roadmap Initiative adapted a framework for the systematic validation of oncological biomarkers to cerebrospinal fluid (CSF) AD biomarkers—encompassing the 42 amino-acid isoform of amyloid-β (Aβ42), phosphoryl

A numerical framework for mechano-regulated tendon healing-Simulation of early regeneration of the Achilles tendon

Mechano-regulation during tendon healing, i.e. the relationship between mechanical stimuli and cellular response, has received more attention recently. However, the basic mechanobiological mechanisms governing tendon healing after a rupture are still not well-understood. Literature has reported spatial and temporal variations in the healing of ruptured tendon tissue. In this study, we explored a c
