This study investigates the potential loss of memory details as a consequence of making successful associative inferences using the associative inference (AI) paradigm with naturalistic stimuli mimicking realistic interactions (AB,BC,and AC). It also aims to further our understanding of the mechanisms involved in the production of integrated memory representations—whether through integrative encod

This thesis presents an approach to improving pulse processing in singlephoton spectroscopy, focusing on crosstalk detection and correction in x-ray microcalorimeters. The work integrates advanced mathematical models, including Jacobian and Hessian computations, Hamiltonian Neural Networks (HNNs), and the application of negative probabilities to optimize Shannon entropy. These models are embedded

Wireless Power Transfer (WPT) is increasingly utilized across various practical domains, requiring continual development and optimization of supporting technologies. An essential aspect of this progress is the efficient testing of WPT Systems. This thesis explores optimization of the testing process using Machine Learning(ML) and data analysis, applied on historical data represented by test outcom

This thesis explores the state-of-the-art methods for the optimization of Wireless Power Transfer (WPT) for Radio Frequency (RF) energy harvesting with a view of increasing the efficiency of the Radio Frequency to Direct Current (RF-to-DC) conversion, which is a key parameter in the creation of Zero Energy Devices (ZEDs) in the context of Internet of Things (IoT). The research focuses on waveform

Safe and clean drinking water delivery is challenged by climate change, as elevated temperatures can promote the growth of pathogens and other detrimental microorganisms. The microbial processes underlying drinking water production in slow sand filters (SSFs) are largely uncharacterized, limiting the possibilities of improving this technology. Periodical clogging, potentially by microbes, disrupts

The dynamics of China’s complex policy process, shaped by the decentralization reforms of the 1980s, remain the subject of much discussion. As China spent three years adhering to its eradication strategy in response to the COVID-19 pandemic, it seems that the relevant theories from the past need to be updated. The purpose of this study was to understand how irrational decisions were made and why u

In this written study, I have researched video game music from the 90’s and early 2000’s to see what I can learn from the process of composing music for video games, as well as how the hardware and software capabilities of the game consoles shaped the music. First it presents my own background and relation to the subject, next it establishes what functionally separates video game music from conven

Intersections have long been recognized as high-risk areas for traffic accidents, with vehicle collisions in Non-Line-of-Sight (NLoS) scenarios resulting in significant economic and human losses. This thesis investigates a vehicle collision avoidance system that integrates Machine Learning (ML), wireless communication technologies, and sensor fusion with Global Navigation Satellite System (GNSS) p

The invaders vs. the protectors: who wins the battle? Pseudomonas aeruginosa or in short PsA is a type of microorganism, also known as “bacteria” or “germ” or “bug”. It is very tiny and invisible to our naked eyes. This germ is found everywhere in places like soil, and water. PsA can get into the human body through wounds and other injuries and make people sick. To prevent humans from getting inf

Utforskandet av nya roller av komplement proteinet C3 Komplementsystemet är en uråldrig evolutionär mekanism i det medfödda immunförsvaret och funkar som en av kroppens första försvarslinje. I detta gamla system finns det ett protein som sticker lite mer, ett protein som har en central roll i komplementsystemet, nämligen komplement protein C3. Inte nog med att den har en viktig roll i framkallninThe complement system is an ancient component of the immune system, comprising three pathways: classical, lectin and alternative pathways. Central to these pathways is complement component C3, which converges the three pathways. C3 can be enzymatically cleaved into C3a which functions as an anaphylatoxin, and C3b, which functions as an opsonin. Previously, C3 was understood as a serum protein, how

Abstrakt Bakgrund: Personalbrist i primärvården har lett till svårigheter att tillgodose patienters vårdbehov. Distriktssköterskor har i tidigare studier beskrivit att deras kompetens och arbetsområde inte prioriterats av chefer och övrig primärvårdspersonal. Konsekvens till följd av detta ledde till att deras hälsofrämjande och sjukdomsförebyggande arbete inte hanns med trots att ett av primärvå

With the persistent phenomenon of rapid urbanization, cities worldwide are in a constant state of change. This transformation extends to the underlying "urban fabric" that encompasses the distinct segments that collectively shape the identity and character of a city. These segments can be formally categorized as districts, boroughs, neighborhoods, or wards. However, at a deeper level fam

Today aromatic ring flipping has become a classic example to highlight the highly dynamic character of proteins. These dynamics occur when the aromatic side chains in phenylalanine and tyrosine turn 180o around its Cβ–Cγ axis, also known as its χ2 dihedral. Discovered in the 1970s’ these ring flippings are a common internal probe used in NMR spectroscopy to understand the protein interior dynamics

Bakgrund: Distriktssköterskans förskrivningsrätt inom primärvården bidrar till effektivisering och förbättring av vårdtillgängligheten inom hälso- och sjukvården. Trots potentiella fördelar finns det distriktssköterskor som inte alltid använder förskrivningsrätten. För att optimera användningen av förskrivningsrätten behövs ökad kunskap om distriktssköterskors erfarenhet i rollen som förskrivare.

Bakgrund: Sverige har upplevt en demografisk förändring där 20% av befolkningen har utländsk bakgrund vilket skapar nya krav på hälso- och sjukvården. Hudbedömning är särskilt utmanande eftersom variationer i hudfärg påverkar diagnos och behandling. För att undvika felbedömningar och upprätthålla en god vårdkvalitet behöver vårdpersonal, inklusive distriktssköterskor, kunskap om melaninrik hud. SBackground: Sweden has experienced a demographic shift, with 20% of the population now having a foreign background, which creates new demands on the healthcare system. Skin assessment is particularly challenging as variations in skin color impact diagnosis and treatment. To avoid misdiagnoses and maintain high-quality care, healthcare professionals, including district nurses, need knowledge about

Previous research has shown that conducting scientific research aimed at studying human behavior in a virtual environment in the context of safety is feasible. However, most applications of this kind are done with a primary focus on the visual aspects of the virtual environment. This study investigates if (a) a visual and auditory recreation of a real-world environment in Virtual Reality (VR) for
