Simulerad patientdata och AI för förbättrad upptäckt av förmaksflimmer År 2030 förväntas upp emot 17 miljoner människor i Europa lida av förmaks-flimmer, en sjukdom med mycket allvarliga konsekvenser. Denna studie utforskar användningen av simulering och maskininlärning för att effektivisera diagnostiseringen, och därigenom potentiellt förebygga uppemot 20% av alla strokes. I Sverige uppskattas Atrial fibrillation (AF) is an arrhythmia distinguished by irregular heartbeats, which has seen a significant rise in prevalence globally. Due to the risk of strokes, the condition necessitates early detection and intervention to prevent severe complications, highlighting the critical role of early and precise detection techniques. To effectively train and validate machine learning (ML) models, ha

The analysis of glacier mass changes in northern Sweden from 2003 to 2023 employed the non-repeat observation method, utilizing data from altimetry data ICESat and ICESat-2, along with Swedish national DEM and RGI v7.0 glacier boundary. The total volume decreased by -2.78 ± 0.58 km³, corresponding to a total mass loss of 10.41 ± 6.60 m w.e. over the past two decades. These changes contribute appro

The aim of this thesis is to explore how contextual factors shape experiences of work-related precariousness in a sparsely populated municipality in northern Sweden. In the thesis, the concept of precariousness is operationalized as relating to three dimensions: income, employment stability and employability, and access to social security. These dimensions are explored qualitatively through semi-s

The purpose of this essay is to se if the mental illness of Swedish children has deteriorated or if it is a rhetorical issue. Are the newspapers overreacting and spreading the wrong messages?. Children seeking relief have increased, and the queues are long to get an appointment to a psychiatrist at the children- and youth psychiatry clinic. The daily newspapers are reporting that the numbers of gi

Popular science summary Growth promoting effects of Trichoderma harzianum on sugar beet Imagine if a plant could be prepared to a pathogen attack before the attack occurs, or if a plant could grow stronger, without an excessive addition of inorganic chemicals. It can, it just need a little help from a fungus. The fungus that stimulates plants is called Trichoderma harzianum. It induces both p

This report investigates the possibility of implementing a high-quality, regional, rubber-wheled based public transport system with train-like features to a lower cost than that of a traditional raliway. In order to be regarded as fulfilling this goal, the system, hereafter called rubber-wheel trains, must both be similar enough to railways to be regarded as trains by the passengers – and also be

The Campanian marine strata from Åsen, north east part of the Kristianstad Basin (southern Sweden) contain a most diverse vertebrate and invertebrate marine fossil assemblages. A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. The succession is divided into two zones, the latest early Campanian Belemnellocamax mammilatus Zone

Global mean temperature has been observed to increase over the last hundred years; this increase is coupled with a global increase of warm extreme indices and a decrease in cold extreme indices. In this study, daily observations of mean and extreme temperatures from ten different weather stations in Sweden during the time period 1961-2010 were analyzed. A warming trend was identified for every dat

Genom att slänga bort viss information från en komprimerad video och sedan återskapa sekvensen i realtid kan vi minska behovet av lagringsutrymme för adaptiv videostreaming med 20–30%. Detta med helt bibehållen bildkvalité eller endast små försämringar. ==================== Adaptiv streaming Streaming är ett populärt sätt att skicka video över internet där en sekvens delas upp i korta segment soVideo content is the dominant traffic type on mobile networks today and this portion is only expected to increase in the future. In this thesis we investigate ways of reducing bit rates for adaptive streaming applications in the latest video coding standard, H.265 / High Efficiency Video Coding (HEVC). The current models for offering different-resolution versions of video content in a dynamic way

More often than not one would encounter a problem, know that the solution has to meet some requirements, but do not how to start or how to progress towards solving it. Motivation for a computer that can solve the problem automatically without explicitly programming it is apparent, i.e. a computer that \programs itself", is greatly desired. The method of genetic programming has demonstrated it

Vi lever idag i en tid av fundamental osäkerhet och striden får vi inte sällan höra står mellan de som går en osäker framtid till mötes och de som nostalgiskt blickar tillbaka. I Vellinge möter vi de som med vemod ser sin ort förändras till vad den inte tycks ha varit förut, liksom de som betraktar ortens utveckling i starkt positiva ordalag. Men vi möter också personer med olika materiella förutsThe following thesis examines two responses to processes of social change within the small town of Vellinge in the province of Scania, Sweden. The experiences of change within the town appear in the guise of two contradicting narratives – one of the town’s progress and the other of its decline – which I aim to approximate from nine in-depth interviews with eight inhabitants conducted in two cycles

Varje år, varje dag, varje timme, dör någon av cancer. Cancer är den näst dödligaste sjukdomen i världen efter hjärt- och kärlsjukdomar. Dessutom drabbar sjukdomen inte bara de som dör. Många lider fysiskt och psykiskt av sin diagnos och nära och kära utsätts för stor oro för sina närstående. Den bispecifika molekylen rVAR2-aCD3 är ett nytt, lovande läkemedel mot cancer som snart kan börja prövas The use of immunotherapy for treating cancer has received a lot of attention in the recent years. The therapy is based on activating or deactivating the patient’s own immune system to help fight the disease. One way of doing this, is using bispecific molecules that can target both cancer cells and T-cells simultaneously. In 2003, a researcher found that the surface protein VAR2, expressed on mala

Tröger’s base molecule has a unique V-shaped cavity and a chiral structure. These molecules can be fused together in a linear fashion to create either tubular structure or zigzag structure. Different fields can be benefited from the applications of these molecules. Previous studies carried out in the Wärnmark group led to 30-step synthesis route to get a linearly fused heptakis-Tröger’s Base anal

Kan virus skydda oss från tarminflammation? En generell uppfattning är virus gör oss sjuka, men faktum är att vår tarm alltid är fylld av biljontals mikroorganismer, allt från bakterier till virus och svamp. Hur kommer det sig då att vi inte är konstant sjuka? Anledningen är att vi lever i symbios med mikroorganismerna. En störning i denna balans kan göra oss sjuka, det kan till och med resulteraIn recent time the prevalence of inflammatory bowel diseases (IBDs) has increased, especially in developed countries. In these diseases the gut homeostasis is disturbed due to multiple factors such as the hosts own immune system, environmental factors, as well as genetic predisposition. The microbiome has previously shown to be important for the maintenance of the gut homeostasis. Despite being le
