We consider channel estimation (CE) in narrowband Internet-of-Things (NB-IoT) systems. Due to the fluctuations in phase within receiver and transmitter oscillators, and also the residual frequency offset (FO) caused by discontinuous receiving of repetition coded transmit data-blocks, random phase noises are presented in received signals. Although the coherent-time of fading channel can be assumed
This article chronicles and analyzes the history of the third sector of R&D in Sweden, which corresponds to an organizational field of research institutes outside academia and private firms. Using secondary sources and governmental documentation, the chronicle begins with the forming of a number of industry-specific and industry-owned institutes in the 1940s and ends with today’s reformed and
Employing the Foucauldian term ‘conduct’, this article explores how social resilience and morale became a target of state intervention in Denmark during the Cold War. ‘Psychological defence’ was a Cold War phenomenon designed to bring an imagined future war into a space of control as well as a tool for the authorities’ exercise of power in case another world war became a reality. Advocating a meth
I den här avhandlingen, syftar jag till att utforska kopplingarna mellan natur, konflikt och fred som bygger på litteratur från freds- och konflikstudier och miljöfredsbyggande. Jag hävdar att miljöfrågor, särskilt relaterade till fördelningen av naturresurser, är centrala för att förstå strukturella förhållanden möjliggör både konflikt och fred. För att svara på förskningsfrågan utforskar jag hurIn this dissertation, I aim to explore the links between nature, conflict, and peace building on literature from peace and conflict studies and environmental peacebuilding. I argue that environmental issues, especially related to the distribution of natural resources, are central to understanding structural conditions allowing for both conflict and peace. In order to answer the research question,
The spatial distribution of an anti-cancer drug and its intended target within a tumor plays a major role on determining how effective the drug can be at tackling the tumor. This study provides data regarding the lateral distribution of sunitinib, an oral antiangiogenic receptor tyrosine kinase inhibitor using an in vitro animal model as well as an in vitro experimental model that involved deposit
Extracting complementary features in parallel pathways is a widely used strategy for a robust representation of sensory signals. Weakly electric fish offer the rare opportunity to study complementary encoding of social signals in all of its electrosensory pathways. Electrosensory information is conveyed in three parallel pathways: two receptor types of the tuberous (active) system and one receptor
We evaluated the diagnostic potential of 24S-hydroxycholesterol (24OHC) in cerebrospinal fluid. At a memory clinic, we investigated subjects with subjective cognitive impairment (SCI, n = 33), mild cognitive impairment (MCI) patients (n = 27), MCI patients with later progression into Alzheimer dementia at follow up (n = 10), and patients with AD (n = 24). We also had a control group of healthy vol
Through a discourse analysis of the end-users’ statements on their choice of primary care, there is a focus on how they use certain discourses in society with regard to which discourses governs their choices of primary care. For this purpose, a group interview was administered in a location in the south of Sweden. It was strategically designed to on the whole include individuals with following cha
To evaluate the risk of urothelial cancer in the upper urinary tract and the bladder, determine the contribution from the different mismatch-repair genes and define clinical characteristics of urothelial cancer in Lynch syndrome.
The addition of the growth stimulator fetal calf serum (FCS, 10%) to rings of rat tail artery causes an increase in [Ca2+]i, accompanied by contraction. This response was inhibited by the calcium entry blocker verapamil (1 microM). To investigate the effect of Ca2+ entry blockade on growth and contractility, rings of rat tail artery were cultured for 4 days in medium with or without FCS and then m
Smooth muscle strips from guinea pig ileum were cultured for 5 days and then tested for contractile properties to investigate whether endogenous polyamines influence excitation-contraction coupling. Inhibition of spermidine and spermine synthesis by culture in the presence of the adenosylmethionine decarboxylase (EC4.1.1.50) inhibitor CGP-48664 (1-10 microM) decreased spermidine and spermine level
PhD Thesis defended at the Department of Mathematics, University of Athens, Greece. It concerns the appropriate formulation and solvability / well-posedness of the Maxwell system for the general linear medium. Special attention is paid in the extraction of the constitutive relation from the axioms that govern the phenomenon. The whole approach is purely functional analytic and operator theoretic.
Cerebral intraventricular haemorrhage (IVH) is the most common cause of severe neurologic impairment following preterm birth in human infants. Ideally, an animal model for cerebral IVH should allow for reliable noninvasive evaluation of haemorrhagic extension and of subsequent development of posthaemorrhagic ventricular dilatation (PHVD). The aim of this study was to evaluate the use of high-frequ
OBJECTIVE: To assess the reliability of 4 gait performance tests in individuals with late effects of polio. DESIGN: An intrarater (between occasions) test-retest reliability study. SETTINGS: University hospital. PARTICIPANTS: Thirty men and women (mean age 63 +/- 6.4 years) with clinically and electrophysiologically verified late effects of polio. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE
Intestinal ischemia as well as mastocytosis occur in patients with inflammatory bowel disease and irritable bowel syndrome. Our aim was to clarify how ischemia with reperfusion (I/R) affects the structure, enteric neurons, and immune cells in the colon. Rats were subjected to colon ischemia for 1 h and reperfused for 1 day up to 20 weeks; sham-operated rats were used as controls. No structural rem
