One way of meeting the increasing demand for higher data rates is by building denser cellular networks in order to maximize the use of the frequency spectrum. The denser deployment leads to an increased probability of inter-cell interference, the phenomenon where the signal quality experienced by a user served by a cell is lowered because of the transmission from neighboring cells in the network.
Accidents with vehicles happen more often than they should, whether it is by road traffic accidents or maritime accidents out in the sea. One big contributing factor is human error. Distraction, influence of alcohol/drugs, carelessness and speeding are examples of factors that can lead to severe injuries for the passengers, the surrounding people and to infrastructure. By transferring human maneuv
Parkinson’s disease (PD) is the most common neurodegenerative disorder after Alzheimer’s disease and today more than 6 million people are living with PD world-wide (2018). PD is characterized by muscle stiffness, shaking at rest, and postural imbalance. The symptoms are caused by a decreased dopamine (DA) level in the brain due to a gradual loss of DA producing neurons. The cause and trigger of th
Problem: The Milky Way disk consists of two distinct components, the thin and thick disk, each with unique kinematical, elemental, and age-related properties. Among all the properties considered, age stands out as the only one that does not exhibit significant overlap, thereby offering clearer separation between the populations. Stellar ages, determined through isochrone fitting, are reliable main
Foodborne diseases are a growing global concern, and a shift in trends has occurred re garding salmonella infections in Sweden. The purpose of this study is therefore to inves tigate how nursing homes in Sweden work to prevent foodborne infections. The study was conducted through semi-structured interviews with staff at nursing homes and with representatives from inspection authorities to gather
Due to the increasing significance of moth species’ contributions to pollination, and the relatively new advancements of AI and LED within this field of study, there is interest in developing a light trap that is both easier to get a hold of and more adapted to the conditions of a northern country like Sweden. In this study I evaluate one such LED-based Light trap and compare it to a more well-tes
This thesis investigates the use of several acceleration schemes to improve the performance of the primal-dual hybrid gradient algorithm for linear programming (PDLP), a state-of-the-art first-order method for linear programming (LP). The three main acceleration schemes investigated are: Polyak heavy ball momentum, Nesterov acceleration, and steering vectors selected in a residual momentum directi
The report investigates whether ultra-high-frequency ultrasound at 30 MHz can distinguish healthy- from diseased intestinal tissue in infants with Hirschsprung's disease with the same accuracy as 50 MHz. Hirschsprung's disease is defined as the absence of ganglion cells in the distal parts of the intestine. During treatment, the affected sections of the intestine are surgically removed. Th
Studien syftar till att kartlägga entreprenörers anbudsprioritering och ge offentliga beställare kunskap om marknaden för att kunna anpassa sina förfrågningsunderlag. Studien har genomförts som en kvalitativ studie innehållande litteraturstudie, dokumentstudie och intervjustudie. Tre administrativa föreskrifter, AF-delar, har analyserats i dokumentstudien. I intervjustudien har både entreprenad-fThe study aims to map contractors’ bid prioritization and provide public clients with knowledge about the market to be able to adjust their tender documents. The study was conducted as a qualitative study including a literature review, document study, and an interview study. Contractual tender documents were analyzed in the document study. In the interview study, both contractors and public procu
Introduction: Therapeutic proteins are crucial in the treatment of a wide range of diseases. However, the proteins are sensitive to chemical degradation reactions, particularly deamidation and isomerization, which can compromise efficacy and safety. Formulation excipients, such as sugars and non-ionic surfactants, are commonly used to enhance stability, yet their effects on chemical degradation re
Co-pathology is a common feature of neurodegenerative diseases that complicates diagnosis, treatment and clinical management. However, sensitive, specific and scalable biomarkers for in vivo pathological diagnosis are not available for most neurodegenerative neuropathologies. Here we present Proteomics-based Artificial Intelligence for Dementia Diagnosis (ProtAIDe-Dx), a deep joint-learning model
This study investigated the applicability of mixture experimental design-based modeling approach to analyze insecticidal activity of thyme essential oils, particularly focusing on the synergistic interaction of their major constituents against Musca domestica. Chemical compositions of twelve commercially available thyme oils were analyzed using GC-MS, revealing their major constituents to be α-pin
In the last few years there has been an ongoing debate concerning the methods of assessing the quality of public libraries and their services. This study investigates the opinions and needs of the users at four different public libraries in Malm : the local libraries in Bellevueg rden, Limhamn, and Kirseberg, and the main library in central Malm . The purpose was to find out whether different user
Målet med denna studie var att undersöka elevers och lärares uppfattningar om olika mobbningsinterventioners effektivitet på en årskurs 6-9 skola i södra Sverige. Avsikten var även att jämföra dessa två grupper, samt titta på olika aspekter hos elevgruppen så som kön, ålder och involvering i mobbning. Urvalet bestod av 375 elever och 25 lärare. Studiens viktigaste resultat var att lärare skattar iThe aim of this study was to investigate the views of students and teachers, at a middle school in the south of Sweden, about the efficacy of different anti-bullying interventions. The purpose was also to compare these two groups, and look at differences within the student population when it came to their sex, age and involvement in bullying. The sample consisted of 375 students and 25 teachers. T
During this master thesis work that was conducted as a case study together with SWEP International, we have investigated marking standards and marking technologies that support handling of varying customer demands and increased information density. We also studied SWEP’s internal information handling and traceability. We were asked to specifically look at the usefulness of RFID for SWEP, and came
Aims: It has in recent years been established that epigenetic changes contribute to β-cell dysfunction and type 2 diabetes (T2D). For example, we have showed that the expression of histone deacetylase 7 (HDAC7) is increased in pancreatic islets of individuals with T2D and that increased levels of Hdac7 in β-cells impairs insulin secretion. The HDAC inhibitor MC1568 rescued this secretory impairmen
We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other stars and binaries. We discuss the necessary conditions to initiate the process of intermediate mass BH formation and the influence of an IMBH on t
Migratory songbirds are guided by an endogenous programme during their first migration, encoding timing of migration, distance and direction. To successfully perform migration, birds have evolved phenotypic adaptations for flight, fuelling and navigation. Migratory distance in different species of birds is encoded as a period of expressed migratory restlessness, for which the length is correlated
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk-outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk-outcome pairs, and new data
