Different tau biomarkers become abnormal at different stages of Alzheimer's disease, with CSF phospho-tau typically becoming elevated at subthreshold levels of tau-PET binding. To capitalize on the temporal order of tau biomarker-abnormality and capture the earliest changes of tau accumulation, we implemented an observational study design to examine longitudinal changes in Tau-PET, cortical thickn

Measuring the temperature below the surface of a thermal barrier coating (TBC) using a thin phosphor layer is challenging primarily due to the absorption and scattering of laser excitation light and phosphor luminescence as they propagate through the coating. One way to increase phosphor luminescence could be to use upconversion phosphor thermometry, which is investigated in the current study. It

In this paper, we consider a sorting scheme for potentially spurious scattering resonant pairs in one- and two-dimensional electromagnetic problems and in three-dimensional acoustic problems. The novel sorting scheme is based on a Lippmann-Schwinger type of volume integral equation and can, therefore, be applied to structures with graded materials as well as to configurations including piece-wise

We study wave propagation in periodic and frequency dependent materials when the medium in a frequency interval is characterized by a real-valued permittivity. The spectral parameter relates to the quasi momentum, which leads to spectral analysis of a quadratic operator pencil where frequency is a parameter. We show that the underlying operator has a discrete spectrum, where the eigenvalues are sy

Collaboration between academia and society has become a key priority for many higher education institutions (HEIs). In Sweden, this is partly driven by political calls to secure the long-term provision of knowledge, innovation and competitiveness. At the system and institutional level, responses to this are reflected in governance structures and strategic documents. However, those strategic responCollaboration between academia and society has become a key priority for many higher education institutions (HEIs).

The recital is focused on my research involving contemporary voice. My approach to singing research is becoming more systematic as the result of beginning to work on concepts central to the extra-normal voice, term coined by Michael Edward Edgerton. This approach to voice is based on voice science, the aims of which are to investigate the boundaries and/or limits of vocal sound production. In this

The physiological effects of oxygen on Limosilactobacillus reuteri DSM 17938 during cultivation and the ensuing properties of the freeze-dried probiotic product was investigated. On-line flow cytometry and k-means clustering gating was used to follow growth and viability in real time during cultivation. The bacterium tolerated aeration at 500 ml/min, with a growth rate of 0.74 ± 0.13 h-1 which dem

Extending the lifetime of products enables material resource savings and provides an effective resource efficiency strategy within a circular economy paradigm. Although consumer demand for longer lasting products that can be easily repaired has been on the rise, it is not certain that consumers are fully able to identify such products and willing to pay a premium for them. France introduced a mand

In recent years, shared freight systems have emerged in many cities as a new modality of freight transportation. However, little attention has been paid to the impact of a city's socioeconomic status on the characteristics of a shared freight network. To fill this gap, in this study, the structural characteristics of an intra-urban shared freight network are measured from the perspective of comple

Survey data Economic Tendency Survey Swedish households' perceptions of the current rate of inflation and their expectations of the future rate of inflation. They analyse what percentage of households can be considered to be poorly informed about inflation (as their responses devia on te significantly from the historical pattern of inflation), and what characterises these householdsUsing micro-level survey data from the National Institute of EconomicResearch’s Economic Tendency Survey, we find that a relatively largeshare of Swedish households is ill-informed about the rate of inflation inthe economy, with perceived and expected rates of inflation deviatingsubstantially from official measures. Probit analysis of the data indicatesthat such inflation illiteracy is related to
