Background: The novel COVID-19 outbreak has been present for over a year and is a permanent companion impacting daily lives and hurting economics universal. Since the presence of the coronavirus has been directly impacting stock markets and its returns worldwide, an analysis of the impact on the COVID-19 outbreak is inevitable. Therefore, this paper examines the influence of the novel COVID-19 out
This thesis aims to investigate and implement a fault-tolerant energy-efficient RISC-V based system on chip (SoC). Key features of the SoC is the testabil- ity and reliability of the low power on-chip embedded memories. A built-in self- test (BIST) for the on-chip memories has been designed and implemented to run on-demand diagnostic tests to detect manufacturing errors in the memories. It incor
Chile is one of the countries in South American working to achieve energy independence by introducing renewables energy to reduce its greenhouse gas emissions from conventional energy sources. Chile has a variety of water resources from the North to the South, where most of these resources are comprehended by short rivers that are exploited to produce hydro-electric power. Chile has a huge number
Vertical nanowire field effect transistors (NWFETs) have in this diploma work been studied in order to examine possible benefits of introducing a highly doped shell around the nanowire channel. It could be concluded that this new device geometry significantly enhances DC performance metrics. It does however also introduce an additional potential drop which may be large enough to reduce device stab
When cultivating barley (Hordeum vulgare), access to cultivars with shorter flowering time can be helpful in various agricultural settings, such as the effort of expanding agricultural capabilities into colder regions with shorter growing seasons. The recently identified gene Praematurum-b (Mat-b) is known to cause the plants to flower 7 days early on average. This thesis aimed to analyze the effe
This thesis examines whether implied volatility derived from Swedish equity options provides superior predictive information relative to historical volatility for future realized volatility and stock returns, and whether this information improves portfolio risk outcomes. Using monthly option and stock data for OMXS30 firms, the study applies predictive regressions and constructs minimum variance p
This piece of work aims at gaining a better understanding of how cognitive and sensual experiences takes place when we interact within the social encounter processes of shared spaces. The structure of this thesis starts off with a theoretical review based on the aspects of social encounters divided into the following areas: affect theory, the ideal of sympathy, and situated multiplicity. These t
The dynamics of molecules and electrons takes place on timescales of femtoseconds and attoseconds, respectively. This requires ultrashort and intense extreme ultraviolet (XUV) pulses to be able to study them. Two sources that can generate intense XUV pulses are free-electron lasers (FELs) based on self amplified spontaneous emission (SASE) and high-order harmonic generation (HHG)driven by intense
Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. coli ) and pullers (e.g C. reinhardtii ). The occurrence of jets, eddies and flocking have been observed in systems of dens pusher suspension. This phenomenon is called active turbulence. Th
This thesis focuses on the integration of management control system (MCS) and sustainability in companies. Some literatures showed a disconnection between the efficiency of sustainability as a success strategy and management control systems. To research this, we aim at answer two questions. What are the challenges that the companies were faced with when they tried to integrate MCS and sustainabili
AIMS/HYPOTHESIS: Delivery by Caesarean section continues to rise globally and has been associated with the risk of developing type 1 diabetes and the rate of progression from pre-symptomatic stage 1 or 2 type 1 diabetes to symptomatic stage 3 disease. The aim of this study was to examine the association between Caesarean delivery and progression to stage 3 type 1 diabetes in children with pre-symp
Dead microbial cells, commonly referred to as necromass, are increasingly recognized as an important source of both persistent carbon as well as nutrient availability in soils. Studies of the microbial communities associated with decomposing fungal necromass have accumulated rapidly in recent years across a range of different terrestrial ecosystems. Here we identify the primary ecological patterns
The Cenozoic Himalaya-Tibet orogen is generally regarded as the archetypal continental collision zone and is often used as an analogue for interpreting ancient orogenic events. However, given the wide diversity observed in present-day collisional mountain belts, the extent to which such inferences can be made remains debated. In this Review, we compare the metamorphic and magmatic record of the Hi
The purpose of this article is to contribute to a refined perspective on how the practices of everyday life can challenge existing spatial scale relations, as well as produce new ones, and how this in turn can be addressed by planning. The investigation is based on a discussion of empirical studies dealing with the role of migrants in processes of place-making and urban transformation. In the arti
Objective: The aim of this study was to evaluate the contemporary population based incidence of acute lower limb ischaemia (ALI) and factors associated with major amputation/death at one year. Methods: In this retrospective observational study, in hospital, operation, radiological, and autopsy registries were scrutinised to capture 161 citizens of Malmö, Sweden, with ALI between 2015 and 2018. Age
Background Elevated troponin levels are a sensitive biomarker for cardiac injury. The quick and reliable prediction of troponin elevation for patients with chest pain from readily available ECGs may pose a valuable time-saving diagnostic tool during decision-making concerning this patient population. Methods and results The data used included 15 856 ECGs from patients presenting to the emergency r
BACKGROUND: Although death in old age is unavoidable, premature death-defined here as death before age 70 years-is not. To assess whether halving premature mortality by 2050 is feasible, we examined the large variation in premature death rates before age 70 years and trends over the past 50 years (1970-2019), covering ten world regions and the 30 most-populous nations. This analysis was undertaken
This report, part of the CULTIVATE project, investigates the costs and benefits of food sharing initiatives (FSIs) in Barcelona, Spain. The study aims to understand the economic, social, and environmental impacts of FSIs, which include growing and composting together, cooking and eating together, and redistributing surplus food. The research employs a Mobile Research Lab (MRL) approach, combining
