Breaking barriers : a statistical and machine learning-based hybrid system for predicting dementia

Introduction: Dementia is a condition (a collection of related signs and symptoms) that causes a continuing deterioration in cognitive function, and millions of people are impacted by dementia every year as the world population continues to rise. Conventional approaches for determining dementia rely primarily on clinical examinations, analyzing medical records, and administering cognitive and neur

Slaggrus och dammspridning från anläggningsarbete

Vid förbränning av avfall produceras stora mängder slaggrus som både är ett avfall, som kräver hantering, och en resurs, genom dess goda materialegenskaper. Slaggrus definieras i denna studie som sorterad bottenaska från avfallsförbränning. En potentiell spridningsväg för föroreningar från slaggruset vid anläggningsarbete är damning. Damning är en miljöoch hälsofara även utan föroreningar i materi

Because of varied topography and landscape heterogeneity,Tianshan Mountain has extremely complex hydrological processes. Considering that the climate change poses a great threat to the water security,it’s necessary to simulate the change of water elements quantitatively and systematically along with elevation. In this study,we applied the modified FLEXG-Δh model to four classic river basins in Tia

Evaluation of a QT Adaptation Time Estimator for ECG Exercise Stress Test in Controlled Simulation

Slowed adaptation of the QT interval to sudden abrupt heart rate (HR) changes has been identified as a marker of ventricular arrhythmic risk. However, abrupt HR changes are difficult to induce in patients. Quantifying the QT adaptation time in gradual HR changes, as observed in ECGs recording during an exercise stress test, has been recently proposed. The time lag between the QT series and an inst

Effekt på dammförråd och PM10-halter av tunnelstädning

Driftmetoder mot höga partikelhalter orsakade av vägdamm i gatu- och vägmiljöer har under lång tid utvärderats i vanlig gatumiljö. Resultaten är dock ofta förhållandevis svårtolkade på grund av inverkan av meteorologi och omfattande inblandning från andra partikelkällor än just den gata som studeras. För att komma vidare med mer detaljerade studier av metodik och strategi och för att få mer lättol

A Framework for Intelligent Access and Compliance Assurance for High Capacity Transport

High Capacity vehicles (HCV) have dimensions outside general access rules. The High Capacity Transport (HCT) concept consists of roads, vehicles, operations, and regulations. The Intelligent Access (IA) framework gives access to roads only if compliance assurance schemes are used to ensure “the right vehicle is on the right road at the right time with the right axel loads and driven at the right s

Val av vägbeläggning : Hur påverkas buller, partiklar (vägdamm) och rullmotstånd?

En litteraturgenomgång av miljöeffekter relaterade till val av vägbeläggning redovisas utgående från bullerreducerade beläggningar, och med fokus på slitagepartiklar, då det inom området pågår stor inhämtning av ny kunskap. En enkel beskrivning av beläggningar med utgångspunkt från Trafikverkets krav och råd har kompletterats med relationen till de tre områdena buller, partiklar och rullmotstånd.

Underground capsule pipeline logistic system Feasibility study of an urban application

A feasibility study of an underground capsule-pipe system for storing and transporting small items and waste is presented. “Hyperloop for packages” for the last/first/mile/yard all the way to and from the final user in apartments and establishments. In many cases, one capsule of 2 kg can do the same job as a car with 1000 times larger mass. The conclusion is that such a system is technically feasi

Base-Station and RIS Deployment Optimization for Indoor Coverage Enhancement

Reconfigurable intelligent surfaces (RISs) are promising to improve energy efficiency and coverage for 6G [1]. In this paper, we aim to optimize the deployment of BSs and RISs for enhanced coverage in terms of received power. Specifically, an active RIS structure [2] with tuneable power amplification is applied, and a framework of mixed integer linear programming (MILP) is proposed for the optimiz

Translation of the working alliance inventory short revised into Italian using a Delphi procedure and a forward-backward translation

Introduction: Enhancing treatment adherence, especially for chronic diseases, can be achieved through therapeutic alliance, potentially elevating the quality of care. An instrument to evaluate the therapeutic alliance could be beneficial in routine clinical settings, educational environments, and extensive research efforts at national and European levels. In this study, we translated therapist and

Detection of Pre-and Post-Trigger Atrial Fibrillation in Long-Term Photoplethysmogram Signals Acquired in Free-Living

Modifiable factors, such as alcohol or physical exertion, may trigger atrial fibrillation (AF) episodes. Identifying and eliminating these triggers can lead to effective strategies which reduce risk of AF recurrence. This study aims to evaluate pre-and post-trigger AF in long-term photo-plethysmogram (PPG) signals obtained during daily living from patients with paroxysmal AF. Thirty-seven patients

Semantic processing of verbal narratives compared to semantic processing of visual narratives : an ERP study of school-aged children

There is a misconception that pictures are easy to comprehend, which is problematic in pedagogical practices that include pictures. For example, if a child has difficulties with verbal narration to picture sequences, it may be interpreted as specific to spoken language even though the child may have additional difficulties with comprehension of visual narratives in the form of picture sequences. T

“It’s not just the residents who need to be motivated for activity” : a qualitative study of the perspectives of staff on providing activity support for people with psychiatric disabilities in supported housing in Sweden

Background: The goals for staff in Supported Housing for people with psychiatric disabilities include helping to develop the residents’ independence and self-confidence in activities. However, staff have expressed frustration about providing this type of support when motivating residents to engage in meaningful activities and also about the difficulty in finding suitable levels of independence wit

Comparison of PMSM versus PMa-SynRM and IM from an Optimized Electric Vehicle Powertrain Perspective

This study focuses on comparing three electrical machine (EM) topologies to be used in an electric vehicle powertrain. The considered topologies are the permanent magnet synchronous machine (PMSM), permanent magnet assisted synchronous reluctance machine (PMa-SynRM), and induction machine (IM). For this assessment, complete powertrains are optimized for each EM topology. A powertrain optimization

Exposure to common infections may shape basal immunity and potentially HIV-1 acquisition amongst a high-risk population in Coastal Kenya

Introduction: The impact of exposure to endemic infections on basal immunity and susceptibility to HIV-1 acquisition remains uncertain. We hypothesized that exposure to infections such as cytomegalovirus (CMV), malaria and sexually transmitted infections (STIs) in high-risk individuals may modulate immunity and subsequently increase susceptibility to HIV-1 acquisition. Methods: A case-control stud

Variational Pair-Density Functional Theory : Dealing with Strong Correlation at the Protein Scale

Multiconfigurational pair-density functional theory (MC-PDFT) offers a promising solution to the challenges faced by traditional density functional theory (DFT) in addressing molecular systems containing transition metals, open-shells, or strong correlations in general. By utilizing both the density and on-top pair-density, MC-PDFT can make use of a more flexible multiconfigurational wave function

Measures reducing travel by public transport during peak hours

Generally, the cost of public transport has increased. Previous research has identified peak hour traffic as the main cost driver, mostly because the travel demand increases the number of vehicles and drivers needed. The purpose of this study is to identify measures aiming to reduce travel with public transport during peak hours, conducted through a semi-systematic literature review. The measures
