Advances in biomarker technology, digital cognitive assessments, and amyloid-targeting therapies have redefined the opportunities for accurate and early diagnosis and care of Alzheimer's disease (AD). These advances also create new possibilities for intervention before the onset of cognitive impairment. This paradigm shift has increased the focus on Stages 1 and 2 of AD, in which individuals are c
Landslide susceptibility mapping is among the first works for disaster management and land use planning activities in a mountain area like Ganzhou City. The aims of the current study are to assess GIS-based landslide spatial modeling using four models, namely data-driven evidential belief function (EBF), frequency ratio (FR), maximum entropy (Maxent), and logistic regression (LR), and to compare t
In recent years, application of ensemble models has been increased tremendously in various types of natural hazard assessment such as landslides and floods. However, application of this kind of robust models in groundwater potential mapping is relatively new. This study applied four data mining algorithms including AdaBoost, Bagging, generalized additive model (GAM), and Naive Bayes (NB) models to
Reducing the risk exposure in investment portfolios is a constant topic in financial literature. This thesis aims to discuss and compare the risk level in portfolios of only Eastern or only Western European market indices by studying the correlation within each one of the portfolios. The correlation is estimated with two different methods: the traditional time-series and Solnik and Roulet’s (2000)
The most famous theory of family economics is probably Gary Becker’s Quantity-Quality model. Assuming scarce parental resources, it predicts a negative relationship between family size and adult success. The model assumes that parents have common preferences and that income pooling takes place. However, modern theories of household allocation have shown that the assumption of common preferences is
The infringement of intellectual property rights has devastating effects on trade, the free circulation of goods, employment, development and public health. Rights holders and the companies legitimately exploiting them are the main parties injured by this and in the last few years, infringement has increased by more than 1000%. The Commission has fought against such infringement since the eighties
This thesis is a summary of six papers which concern synthesis of optically active bicyclo[2.2.2]octane derivatives. The derivatives prepared are important building blocks in a study towards a possible replacement of the diterpenoidic part of taxol, (baccatin III), so as to construct a taxol mimic. Some of the derivatives have also been developed into new bidentate ligands. TitaniumIV complexes of
Aims: In the present study, we aimed to evaluate the performance of machine learning (ML) models for identification of acute myocardial infarction (AMI) or death within 30 days among emergency department (ED) chest pain patients. Methods and results: Using data from 9519 consecutive ED chest pain patients, we created ML models based on logistic regression or artificial neural networks. Model input
PAM50 gene expression subtypes represent a cornerstone in the molecular classification of breast cancer and are included in risk prediction models to guide therapy. We aimed to illustrate the impact of included genes and biological processes on subtyping while considering a tumor’s underlying clinical subgroup defined by ER, PR, and HER2 status. To do this we used a populationrepresentative and cl
Introduction: The treatment strategies for a 42-year-old female index patient with moderate Graves’ disease (GD) vary according to several international surveys. The important question whether surveys of treatment preferences in theoretical patient cases also match how real patients are treated has not yet been addressed. Materials and Methods: From a Swedish cohort of 1186 GD patients (TT-12 coho
BackgroundEvaluation of emergency department (ED) performance remains a difficult task due to the lack of consensus on performance measures that reflects high quality, efficiency, and sustainability.AimTo describe, map, and critically evaluate which performance measures that the published literature regard as being most relevant in assessing overall ED performance.MethodsFollowing the PRISMA guide
Context. Positions and proper motions of Gaia sources are expressed in a reference frame that ideally should be non-rotating relative to distant extragalactic objects, coincident with the International Celestial Reference System (ICRS), and consistent across all magnitudes. For sources fainter than 16th magnitude, this is achieved through Gaia's direct observations of quasars. At brighter magnitud
BACKGROUND/AIMS: The aim of this study was to develop a risk model for intraoperative complication (IC) during cataract surgery, defined as posterior capsule rupture and/or zonular dehiscence, and to include previous intravitreal therapy (pIVT) in the model.METHODS: This retrospective register-based study covered patients reported to the Swedish National Cataract Register (SNCR) between 1 January
Purpose: The study aims to explore how concept stores (theoretically) differ from other experience-based retail formats, and hence, how they (practically) contribute to a diversified retail store portfolio. Design/methodology/approach: Case study based on semi-structured, qualitative interviews with seven IKEA retail managers, three industry experts and 26 customers of IKEA concept stores in Londo
Capsule A combination of several biometric measures enables the reliable sexing of the European Bee-eater Merops apiaster, a species with subtle sex differences in plumage and morphometry. Aims To explore variation in biometrics and their suitability to discriminate sex in adult European Bee-eaters Merops apiaster. Methods We sampled populations of a long-distance migratory species with low sexual
Prostatacancer är den vanligaste cancern bland män i Sverige. Varje år insjuknar ca 10 000. Sjukdomen är starkt åldersberoende och är mycket vanlig bland äldre män. Latent cancer (icke kliniskt signifikant) förekommer ofta. Sjukdomen klassificeras som låg, mellan eller högrisk baserat på Gleason summa (tumörens aggressivitet), stadium och PSA. Val av behandling sker utifrån riskgrupp och ålder. LåAbstract Backgound Prostate cancer is the most common form of cancer in men in Sweden. Radiotherapy, including external beam radiation therapy (EBRT) and brachytherapy (BT), is important treatment alternatives to surgery and active surveillance. Precise delivery of the prescribed absorbed dose to the prostate with minimal irradiation of normal tissue, specifically organs at risk, is crucial for op
Grazing can have considerable ecological impacts when managed inappropriately, however livestock production is a significant contributor to global food security and the removal of land from production is not always a viable option. Grazing management practices that incorporate periods of planned rest (i.e. strategic-rest grazing) may be an alternative to grazing exclusion or continuous grazing tha
