Why did Swedish regional net migration rates fall in the 1970s? : The role of policy changes versus structural change, 1945–1985

The relationship between local labour market conditions and regional migration has been widely discussed within research. In Sweden, where interregional migration reached a peak in the 1960s but decreased substantially in the 1970s, the role of economic policy has been especially contended in light of the Swedish model and its official stress on regional mobility. By collecting and creating a new

Aggregate Size Dependence of Amyloid Adsorption onto Charged Interfaces

Amyloid aggregates are associated with a range of human neurodegenerative disorders, and it has been shown that neurotoxicity is dependent on aggregate size. Combining molecular simulation with analytical theory, a predictive model is proposed for the adsorption of amyloid aggregates onto oppositely charged surfaces, where the interaction is governed by an interplay between electrostatic attractio

Pharmacological treatment patterns in neuropathic pain--lessons from Swedish administrative registries

OBJECTIVE: To explore the treatment patterns of patients with a diagnosis related to chronic pain (DRCP) initiating pharmacological treatment indicated for neuropathic pain (NeuP: tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, and anticonvulsants).DESIGN: Retrospective study on administrative registers.SETTING: General population in Western Sweden (one sixth of the countr

The host defense peptide LL-37 is detected in human parotid and submandibular/sublingual saliva and expressed in glandular neutrophils

The human host defense peptide, LL-37, is an important player in the first line of defense against invading microorganisms. LL-37 and its precursor, hCAP18, have been detected in unstimulated whole saliva but no reports showing hCAP18/LL-37 in isolated, parotid, and/or submandibular/sublingual saliva have been presented. Here, we measured the levels of hCAP18/LL-37 in human parotid and submandibul

Utvidgad anlagsbärartestning kan bredda fosterdiagnostiken - Recessiva sjukdomsanlag kan kartläggas hos friska personer inför planerad graviditet

Utvecklingen inom gentekniken har gjort det möjligt att inom sjukvårdens ram undersöka många gener samtidigt genom helgenom-/helexomanalyser. Detta har hittills främst utnyttjats för diagnostik av personer, framför allt barn, med misstänkt ärftliga syndrom.Under de senaste tre åren har tekniken utnyttjats för att bygga upp plattformar att användas för kartläggning av recessiva sjukdomsanlag hos frDue to recent advances in molecular genetic testing, massive parallel sequencing has become possible at an affordable cost for health care. Thus, it is now possible to test healthy young persons for carriership of mutations in many genes for severe recessive genetic conditions – extended genetic carrier testing. The introduction of this test in Swedish health care must be accompanied by ethical co

A hidden cost of migration? Innate immune function versus antioxidant defense

Migration is energetically demanding and physiologically challenging. Migrating birds, for example, need to boost their antioxidant defenses to defeat the pro-oxidants produced during high energetic activity. The enhanced antioxidant defense possibly withdraws limited resources (e.g., energy or micronutrients) from other physiological functions, such as immune defense. Such a trade-off might not o

Both weight at age 20 and weight gain have an impact on sleep disturbances later in life : Results of the EpiHealth study

Study Objectives: Obesity is often associated with impaired sleep, whereas the impact of body mass index (BMI) at younger age and previous weight gain on sleep problems remains unknown. Methods: The present study utilized data from the Swedish EpiHealth cohort study. A total of 15845 participants (45–75 years) filled out an internet-based questionnaire. BMI was calculated from both measured data a

Comprehensive on-line two-dimensional liquid chromatography × supercritical fluid chromatography with trapping column-assisted modulation for depolymerised lignin analysis

Lignin depolymerisation produces a large variety of low molecular weight phenolic compounds that can be upgraded to value-added chemicals. Detailed analysis of these complex depolymerisation mixtures is, however, hampered by the lack of resolving power of traditional analysis techniques. In this study, a novel online comprehensive two-dimensional reversed-phase liquid chromatography (RPLC) × super

Linking multiscale deformation to microstructure in cortical bone using in situ loading, digital image correlation and synchrotron X-ray scattering

The incidence of fragility fractures is expected to increase in the near future due to an aging population. Therefore, improved tools for fracture prediction are required to treat and prevent these injuries efficiently. For such tools to succeed, a better understanding of the deformation mechanisms in bone over different length scales is needed. In this study, an experimental setup including mecha

Solvent control of charge transfer excited state relaxation pathways in [Fe(2,2′-bipyridine)(CN)4]2-

The excited state dynamics of solvated [Fe(bpy)(CN)4]2-, where bpy = 2,2′-bipyridine, show significant sensitivity to the solvent Lewis acidity. Using a combination of optical absorption and X-ray emission transient spectroscopies, we have previously shown that the metal to ligand charge transfer (MLCT) excited state of [Fe(bpy)(CN)4]2- has a 19 picosecond lifetime and no discernable contribution

Mechanism and Rate Constants of the CH3+ CH2CO Reaction : A Theoretical Study

Temperature- and pressure-dependent reaction rate constants have been computed using the Rice-Ramsperger-Kassel-Marcus (RRKM)-Master Equation and transition state theory methods. Three main channels have been shown to dom

Rethinking IS Strategic Alignment : A Middle Management Perspective

IS strategic alignment remains a research phenomenon of key interest, specifically regarding the dimensions of social IS alignment (i.e., shared IS understanding among key organizational members) and intellectual IS alignment (i.e., IS/business strategy congruence). The examination of IS alignment has been predominantly limited to the examination of top ranks within the organization; however, we c

Computationally-efficient modeling of inelastic single crystal responses via anisotropic yield surfaces : Applications to shape memory alloys

Phenomenological constitutive models of inelastic responses based on the methods of classical plasticity provide several advantages, especially in terms of computational efficiency. For this reason, they are attractive for the analysis of complex boundary value problems comprising large computational domains. However, for the analysis of problems dominated by single crystal behavior (e.g., inclusi

The impact of deuteration on natural and synthetic lipids : A neutron diffraction study

The structural investigation of cellular membranes requires access to model systems where the molecular complexity is representative of the cellular environment and that allow for the exploitation of structural techniques. Neutron scattering, and in particular neutron diffraction can provide unique and detailed information on the structure of lipid membranes. However, deuterated samples are desira

Making Minimal Solvers for Absolute Pose Estimation Compact and Robust

In this paper we present new techniques for constructing compact and robust minimal solvers for absolute pose estimation. We focus on the P4Pfr problem, but the methods we propose are applicable to a more general setting. Previous approaches to P4Pfr suffer from artificial degeneracies which come from their formulation and not the geometry of the original problem. In this paper we show how to avoi

Classification of one-dimensional non-stationary signals using the Wigner-Ville distribution in convolutional neural networks

In this paper we argue that the Wigner-Ville distribution (WVD), instead of the spectrogram, should be used as basic input into convolutional neural network (CNN) based classification schemes. The WVD has superior resolution and localization as compared to other time-frequency representations. We present a method where a large-size kernel may be learned from the data, to enhance features important

Export-led innovation : The role of export destinations

This article analyzes the effect of exporting activity on the innovative performances of firms in France, Germany, Italy, Spain, and UK. It argues that the positive effect of exporting on innovation usually found in the literature varies according to the specific destinations of exports, and it identifies two dimensions along which export destinations might differ: the level of foreign technologic
