Optimal Trilateration Is an Eigenvalue Problem

The problem of estimating receiver or sender node positions from measured receiver-sender distances is a key issue in different applications such as microphone array calibration, radio antenna array calibration, mapping and positioning using UWB or using round-trip-time measurements between mobile phones and WiFi-units. In this paper we address the problem of optimally estimating a receiver positi

Lung Cancer Risk in Never-Smokers of European Descent is Associated With Genetic Variation in the 5p15.33 TERT-CLPTM1Ll Region

Introduction: Inherited susceptibility to lung cancer risk in never-smokers is poorly understood. The major reason for this gap in knowledge is that this disease is relatively uncommon (except in Asians), making it difficult to assemble an adequate study sample. In this study we conducted a genome-wide association study on the largest, to date, set of European-descent never-smokers with lung cance

Band-selective dynamics in charge-transfer excited iron carbene complexes

Ultrafast dynamics of photoinduced charge transfer processes in light-harvesting systems based on Earth-abundant transition metal complexes are of current interest for the development of molecular devices for solar energy conversion applications. A combination of ultrafast spectroscopy and first principles quantum chemical calculations of a recently synthesized iron carbene complex is used to eluc

Work identity development in young adults with mental health problems

Background: How we identify ourselves is strongly related to employment. Young adults are a vulnerable group with regard to entering the Labor market. If they also have mental health problems, entering becomes more difficult and increases risk of early marginalization. Nevertheless, working can be essential for personal recovery process. Aims: To explore experiences of young adults with mental hea

Exit as governance : do blockholders affect corporate innovation in large US firms?

Using a sample of large US firms, this study shows that blockholders in combination with liquidity can contribute positively to innovation (R&D investments). We contribute to the literature on managerial myopia that has focused mainly on large owners and their type (short-term/long-term). Our results are in line with recent theoretical studies arguing that blockholders in combination with mark

Fiske och säl – en analys av möjligheter till samexistens

Det småskaliga fisket längs Östersjökusten minskar idag i snabb takt. Det finns mångamöjliga orsaker till utvecklingen. En som uppmärksammats är de växande sälstammarna i Östersjön eftersom de konkurrerar med människan om fiskresursen. Både det kustnära fisket och sälen är viktiga delar av Östersjöns kultur- och naturliv, men de senasteårens utveckling tyder på att det är svårt för småskaligt fisk

Age and geographic patterns of Plasmodium falciparum malaria infection in a representative sample of children living in Burkitt lymphoma-endemic areas of northern Uganda

Background: Falciparum malaria is an important risk factor for African Burkitt lymphoma (BL), but few studies have evaluated malaria patterns in healthy BL-age children in populations where both diseases are endemic. To obtain accurate current data, patterns of asymptomatic malaria were investigated in northern Uganda, where BL is endemic. Methods: Between 2011 and 2015, 1150 apparently healthy ch

Risk prediction to inform surveillance of chronic kidney disease in the US Healthcare Safety Net : A cohort study

Background: The capacity of electronic health record (EHR) data to guide targeted surveillance in chronic kidney disease (CKD) is unclear. We sought to leverage EHR data for predicting risk of progressing from CKD to end-stage renal disease (ESRD) to help inform surveillance of CKD among vulnerable patients from the healthcare safety-net. Methods: We conducted a retrospective cohort study of adult

Plasma-free fatty acids, fatty acidebinding protein 4, and mortality in older adults (from the cardiovascular health study)

Plasma-free fatty acids (FFAs) are largely derived from adipose tissue. Elevated levels of FFA and fatty acidebinding protein 4 (FABP4), a key cytoplasmic chaperone of fatty acids, have been associated with adverse cardiovascular outcomes, but limited data are available on the relation of these biomarkers with cardiovascular and total mortality. We studied 4,707 participants with a mean age of 75
