Importance: While clinical disease stages remained largely unchanged in the 2024 update of the Alzheimer disease (AD) criteria, tau-positron emission tomography (PET) was introduced as a core biomarker and its spatial extent was incorporated into the revised biological stages of the disease. It is important to consider both the clinical and the biological stages and understand their discrepancies.

A search is presented for a heavy scalar (H) or pseudo-scalar (A) predicted by the two-Higgs-doublet models, where the H/A is produced in association with a top-quark pair (tt¯H/A), and with the H/A decaying into a tt¯ pair. The full LHC Run 2 proton–proton collision data collected by the ATLAS experiment is used, corresponding to an integrated luminosity of 139fb-1. Events are selected requiring

INTRODUCTION: Amyloid-induced tauopathy drives clinical decline in Alzheimer's disease (AD). Because age and sex shape tau trajectories, defining patient-centered amyloid thresholds for tauopathy onset could facilitate pre-tauopathy AD identification and aid treatment decisions and prognosis. METHODS: By including two samples (Alzheimer's Disease Neuroimaging Initiative [ADNI, n = 301]; and 18F-AV

In this paper, we investigate a Multi-layer Aerial system for GenAI inference at the Edge (MAGE). Therein, ground user equipments (UEs) request image synthesis services from a remote base station (BS) that leverages the Latent Diffusion Model (LDM) for image generation. Multiple Unmanned Aerial Vehicles (UAVs) are deployed to serve the UEs for relaying their images and prompts to the BS. To reduce

The production of fast pyrolysis bio-oil (FPBO) from secondary biomass is a promising technique for the production of liquid biofuels. However, the resulting FPBO is often viscous and chemically unstable, requiring significant upgrading while also being difficult to work with. To overcome this issue, FPBO can be hydrotreated using slurry hydrotreatment, which has a long history as a processing tec

Public procurement has the potential to serve as a strategic driver for circular economy implementation and urban sustainability transitions. Purpose: This study explores how municipalities incorporate circular requirements into construction project procurement processes. The aim is to identify practical strategies that support circular implementation in construction projects. Methodology: U

This study explores the effectiveness of combining Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) for identifying internal erosion processes in embankment dams. A small-scale test dam was built in Älvkarleby, Sweden, with deliberately embedded but undisclosed defects to test monitoring capabilities. Daily ERT and IP measurements were collected during 4.5-year years, and anal

This paper presents a two-phase heuristic methodology aimed at the reconfiguration of a radial distribution network with the objective of minimizing the computational time. In the preliminary phase of the operation, all network switches are in a closed state, and it is proposed that a subsequent switch opening methodology be employed to achieve a configuration that approximates optimal radial char

Populärvetenskaplig sammanfattning: Kvävekoncentrationen i den gröna biomassan hos vegetation är involverad i många olika biokemiska processer i det terrestra ekosystemet. Till exempel så påverkar den fotosyntesen, förmultning och evaportanspirationen, för att nämna några. Därför är den också ofta en av grundparametrarna och drivkraften i olika ekosystem-modeller. Att mäta kvävehalten hos blad/barNitrogen in the green biomass of vegetation plays an important role in many biochemical processes in the terrestrial ecosystems, and often used as an input parameter to ecosystem models. It strongly influences photosynthetic rate, decomposition, and evaportanspiration, to name a few. Measuring nitrogen in field involves a lot of time and money, and it would be valuable if this part of the data col

Syftet med vår uppsats var att utreda behovet av multilingvistisk kundservice på den svenska marknaden samt att studera hur företag hanterar kunder med icke-svensk bakgrund. Vårt sekundära syfte vara att undersöka affärsmöjligheter för ett multilingvistiskt call center. Uppsatsens teoretiska ramverk består av kundbaserad teori, där teorier kring Customer Relation Management, kundservice, call cent

This thesis explores the correlation between national role conceptions, national identities and sensemaking processes among South Korean and Swedish policy influencers during the Sunshine Policy years of 1998-2003. The study relies on in depth semi structured interviews with 10 policy influencers who work with North Korea policies. Starting from Holsti’s (1970) national role conceptions and Weick’

With the advent of digitalization, the economy of the world is quickly changing itself and Indian Small and Medium Enterprises (SMEs) are the front runners. This study sheds light on how digital transformation is crucial to support the growth, competitiveness, and sustainability in the present business environment, and how digital transformation is important to the SMEs in India. To encourage SMEs

Household expenditure patterns in Ukraine were explored with a focus on clustering techniques to uncover socioeconomic insights and inform policy interventions. Using an officially published Household Income Survey dataset for 2021, the research applies advanced machine learning models, including k-means, DBSCAN, and PCA, to analyze spending habits and identify household profiles with distinct exp

This thesis critically examines the Swedish ‘Security Zones’ legislation, the associated governmental discourse on organised criminality, and their implications for equality and racial justice. Through a critical discourse analysis, the thesis illustrates how the extended discretion afforded through the legislation facilitates law enforcement’s capacity for racial profiling and discrimination. It

Problem Statement: Sandvik Rock Processing is in the need for a classification tool, which can help them improve their inventory management. Currently, there are problems with inefficiencies with deficit as well as excess in inventory. The new classification shall the basis for the differentiation of service levels and facilitate a shared view on items’ importance. Purpose: The purpose of this th
