This letter presents measurement results for a low supply voltage 28 GHz beam steering PLL, designed in a SiGe bipolar process with fT=200 GHz. The PLL, designed around a QVCO, is intended for a beam steering 81-86 GHz E-band transmitter. Linear phase control is implemented by variable current injection into a Gilbert type phase detector, with a measured nominal phase control sensitivity of 2.5 °/

We investigate the prognostic significance of the pro-angiogenic cytokine vascular endothelial growth factor (VEGF), urokinase-type plasminogen activator (uPA), plasminogen activator inhibitor 1 (PAI-1), and S-phase fraction (SPF) for distant disease free survival (DDFS) in 219 premenopausal patients with node-negative breast cancer (NNBC). In univariate analysis significantly shorter DDFS was obs

Context: CCAAT/enhancer binding protein alpha (C/EBPalpha) is a transcription factor involved in adipogenesis and hepatic glucose and lipid metabolism. Objective: To test the hypothesis that adipose tissue C/EBPalpha regulates genes in lipid and glucose metabolism and to test for association between a polymorphism in C/EBPalpha and metabolic parameters. Design and Methods: Adipose tissue C/EBPalph

Fibulin-1, a circulating extracellular matrix glycoprotein, has been associated with arterial disease and elevated N-terminal prohormone B-type natriuretic peptide (NT-proBNP) in diabetes. Soluble urokinase plasminogen activator receptor (suPAR), a marker of inflammation, has been associated with subclinical atherosclerosis. Therefore, we aimed to explore the interplay between these biomarkers and

Purpose: The purpose of this thesis is to explain the investment decision process in a newly established market that is characterized by uncertainty. Methodology: The research has a qualitative character and is based on a case study based on the biogas industry in Sweden. Theoretical perspectives: The theoretical framework of the study is based on the three phases of an investment process: The

A concept for a bee, - and beekeeper friendly horizontal top bar beehive for northern climates, aiming to provide a platform for discussion and further development of bee keeping methods. An ergonomic alternative to the heavy handled traditionally used vertical hives, Apivaria aims to offer an older generation a possibility to postpone retirement from beekeeping, while introducing a new generation

The main idea with this thesis is to discuss the situation of the parent and the teacher of a child with attention deficit hyperactivity disorder (ADHD). Previous research on the parents’ and the teachers’ per-spective of the children has helped me to understand the complexity of the disorder. I have analyzed a single case of a child from Poland who came with his parents to Sweden and started educ

Climate change and environmental awareness have been a focus topic in the past years due to the increase of greenhouse emissions in the atmosphere. A significant part of the problem is the greenhouse gas emissions caused by the construction industry, whether in the early stages of construction or over the life of a building. In order to reduce human impact, several actors in the building and const

Flood risk is influenced not only by climate change but also underlying factors including unplanned urbanization, environmental degradation, poverty, social inequalities and weak governance. Given its complexity, effective flood risk management requires a better understanding of its conceptual context and comprehensive assessments that beyond hazard consider exposure, vulnerability and capacity. T

Coffee is associated with decreased breast cancer risk, but the impact of body mass index (BMI) in combination with coffee consumption on prognosis is unclear. The suppressive effect of coffee constituents on the insulin-like growth factor receptor 1 (IGF1R) levels in breast cancer cells may play a role. The aim was to investigate the prognostic impact of coffee consumption and possible associatio

Purpose: This study aims to explore negotiations of hope in everyday life for families where a child with spinal muscular atrophy (SMA) has received a new drug treatment. Methods: A narrative design was used, drawing on interviews and participant observations in two families with children with SMA, types 1–2, to situate family experiences of hope in everyday life. Narrative analysis was used on th

American playwright Tony Kushner’s characters in Angels In America: Millenium Approaches (1992) and Angels In America: Perestroika (1994) are faced with the consequences of the HIV AIDS crisis in 1980s New York City and all attempt to escape from their physical or psychological reality to another. Previous analysis on these plays have focused on how broader societal issues affect the characters in

Predicting live birth after the first IVF/ICSI treatment is challenging, as many factors may interact to affect IVF/ICSI outcomes. Adenomyosis is one factor that impacts live birth rates. Machine learning algorithms have been shown valuable for detecting complex dependencies and predicting outcomes in different clinical settings. We aimed to develop a prediction model for live birth after IVF/ICSI
