Michelson interferometers have been routinely used in various applications ranging from testing optical components to interferometric time-resolved spectroscopy measurements. Traditionally, plate beamsplitters are employed to redistribute radiation between the two arms of an interferometer. However, such an interferometer is susceptible to relative phase fluctuations between the two arms resulting

Plasma levels of tau phosphorylated at threonine-217 (p-tau217) is a candidate tool to monitor Alzheimer's disease. We studied 150 cognitively unimpaired participants and 100 patients with mild cognitive impairment in the Swedish BioFINDER study. P-tau217 was measured repeatedly for up to 6 years (median three samples per person, median time from first to last sample, 4.3 years). Preclinical (amyl

Farmers know much more than we think, and they are keen to improve their knowledge in order to improve their farms and increase their income. On the other hand, decision-makers, organizations, and researchers are increasing their use of citizen volunteers to strengthen their outcomes, enhance project implementation, and approach ecosystem sustainability. This paper assesses the role of citizen sci

Gambling disorder is associated with severe financial, social, and psychological consequences, but treatment-seeking rates have been described to be low. Apart from formal treatment, motivational interventions in nontreatment-seeking high-risk gamblers have been shown to be promising. However, little is known about the effectiveness and acceptability of such motivational interventions carried out

To predict the final geometry in thermo-mechanical processes, the use of modeling tools is of great importance. One important part of the modeling process is to describe the response correctly. A previously published mechanism-based flow stress model has been further developed and adapted for the nickel-based superalloys, alloy 625, and alloy 718. The updates include the implementation of a solid

The present work illustrates the potential of a new diagnostic technique that allows the measurement of the coronal magnetic field strength in solar active regions by utilizing a handful of bright Fe x and Fe xi lines commonly observed by the high-resolution Hinode/EUV Imaging Spectrometer (EIS). The importance of this new diagnostic technique is twofold: (1) the coronal magnetic field is probably

Sterile liver inflammation and fibrosis are associated with many liver disorders of different etiologies. Both type 1 and type 2 inflammatory responses have been reported to contribute to liver pathology. However, the mechanisms controlling the balance between these responses are largely unknown. Natural killer T (NKT) cells can be activated to rapidly secrete cytokines and chemokines associated w

This paper describes a search for beyond the Standard Model decays of the Higgs boson into a pair of new spin-0 particles subsequently decaying into b-quark pairs, H→aa→(bb¯)(bb¯), using proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider at center-of-mass energy s=13 TeV. This search focuses on the range 15 GeV≤ma≤30 GeV, where the decay products are collimat

Background: The Mendelian Society of Lund launched Hereditas in 1920. The purpose of this article is to give an overview of Hereditas’s hundred-year existence, focusing on the conditions for a learned society to publish a scientific journal, and the journal’s importance for the publication and dissemination of genetic research. The article focuses on the historical development of the journal and a

The cosmic origin of fluorine, the ninth element of the periodic table, is still under debate. The reason for this fact is the large difficulties in observing stellar diagnostic lines, which can be used for the determination of the fluorine abundance in stars. Here we discuss some recent work on the chemical evolution of fluorine in the Milky Way and discuss the main contributors to the cosmic bud

Background: Women account for 60% of all stroke deaths and are more often permanently disabled than men, despite their higher observed stroke incidence. Considering the clinical population affected by stroke, an obvious drawback is that many pre-clinical and clinical studies only investigate young males. To improve therapeutic translation from bench to bedside, we believe that it is advantageous t

Introduction The potential impact of socio-economic condition on virological suppression during antiretroviral treatment (ART) in sub-Saharan Africa is largely unknown. In this case-control study, we compared socio-economic factors among Ethiopian ART recipients with lack of virological suppression to those with undetectable viral load (VL). Methods Cases (VL>1000 copies/ml) and controls (VL6 mont

From 1905 to 1940, 4% of all children and young people placed under Danish child welfare were discharged because they were perceived to be unresponsive to upbringing and care. Gradually a new concept was developed to describe the reason for their failure to transition to well-behaved children: “incorrigibility”. Based on the rise and use of this concept, this article examines the relationship betw

En biografi om en bok: Codex Upsaliensis B 68 från 1430 är en bokhistorisk studie om en medeltida handskrift och dess levnadshistoria, från tillblivelsen till mitten av 1700-talet. Handskriften är en illustrerad medeltida avskrift av Magnus Erikssons landslag men den är också och ett vittne från de tidsperioder som boken varit i omlopp. Antologin har som bakgrund ett seminarium som hölls 2017 på U

Reflections on the impact of Covid-19 and the subsequent state measures on migrant workers.

An interview with Professor Nikita Dhawan, who is a professor for Political Science with focus on Gender Studies. A conversation on social theory, postcolonial theory, queer politics and feminist activism

We present a mathematical model for the simulation of the development of an outbreak of COVID-19 in a slum area under different interventions. Instead of representing interventions as modulations of the parameters of a free running epidemic we introduce a model structure that accounts for the actions but does not assume the results. The disease is modelled in terms of the progression of viremia re

The present dissertation investigates how beginner learners process grammatical tone in a second language and whether their processing is influenced by phonological transfer. Paper I focuses on the acquisition of Swedish grammatical tone by beginner learners from a non-tonal language, German. Results show that non-tonal beginner learners do not process the grammatical regularities of the tones but

Background: Problem gambling is a public health issue affecting both the gamblers, their families, their employers, and society as a whole. Recent law changes in Sweden oblige local and regional health authorities to invest more in prevention and treatment of problem gambling. The economic consequences of gambling, and thereby the potential economic consequences of policy changes in the area, are
