Integrated Processors (IP) are meant to supply algorithm-specific cores to a micro-electronic system. They are usually developed separately, and upon success turned into a part, that either by programming or by configuration can be re-used within many systems. This paper looks at architectures for Cellular Neural Networks (CNN) to become realized as IP. First current digital implementations are re
We describe a simple method to detect significant changes of the total ozone column from global (diffuse and direct) zenith sky measurements taken at the Earth’s surface. The calculation of the total ozone column relies on measured irradiance at two wavelengths in the ultra violet part of the solar spectrum. One of these (i.e. 306 nm) are appreciable absorbed by ozone whereas the other (i.e. 360 n
We report on the status of the Baltic/Wadden Sea flyway Eider population based on trends in breeding and wintering numbers throughout the region, supplemented by changes in the sex ratio and proportion of young Eiders as monitored in the Danish hunting bag. At the flyway scale, total numbers of breeding pairs decreased by 48% during 2000-2009, after relatively stable breeding numbers in 1991-2000.
The International Commission on Radiological Protection (ICRP) does not have a specific publication or recent detailed advice on acceptability criteria and suspension levels for medical radiological equipment. However, a number of the Commission's publications clearly stress the need to carry out acceptance testing of radiological equipment. Such general recommendations are frequent in earlier and
The performance of traditional continuous-time (CT) delta-sigma analog-to-digital converters (ADCs) is limited by their large sensitivity to feedback pulse-width variations caused by clock jitter in their feedback digital-to-analog converters (DACs). To mitigate that effect, we propose a modified switched-capacitor (SC) feedback DAC technique, with a variable switched series resistor (SR). The arc
The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. The main part of the work in the thesis concerns control of the microbial substrate uptake rate by manipulat
BACKGROUND: Roux-en-Y gastric bypass is a bariatric procedure of choice. There is evidence supporting a small isolated pouch and a wide anastomosis. Gastric vascular anatomy renders the ventral aspect less suited for anastomotic construction. The lesser curvature has abundant blood supply that should preferably not be interfered with. Terminal anastomosis is a logical choice. METHODS: We devised a
Background: Home mechanical ventilation (HMV) and long-term oxygen therapy (LTOT) are the two treatment alternatives when treating respiratory insufficiency in patients with kyphoscoliosis. We aimed to study the effect on survival with regard to HMV or LTOT alone in patients with respiratory insufficiency due to kyphoscoliosis. Methods: Swedish patients with nonparalytic kyphoscoliosis (ie, scolio
The cAMP-elevating pituitary adenylate cyclase-activating polypeptide (PACAP) stimulates insulin release in pancreatic B-cells. Here, we have investigated its potentiating action in rat insulinoma INS-1 cells. In intact cells, PACAP-27 (100 nM) stimulated glucose-induced insulin secretion by >60%. Using the patch-clamp technique with single-cell exocytosis monitored as increases in cell capacitanc
There is general consensus that children of women with pre-existing diabetes mellitus (PDM) have an increased risk of malformations and neurodevelopmental problems. Whether this is also true for children of women with gestational diabetes mellitus (GDM) is a matter of debate. This study investigated inpatient hospital care up to 10 y of age of children born to GDM and PDM women as a rough estimate
BACKGROUND: To describe the frequency, in some European populations, of the World Health Organisation (WHO) defined metabolic syndrome and to compare the frequency of this syndrome with an alternative definition for non-diabetic subjects, called the insulin resistance syndrome proposed by the European Group for the Study of Insulin Resistance (EGIR). METHODS: Investigators of eight European studie
Objective - To investigate the feasibility of monophasic action potential ( MAP) mapping using an electro-anatomical mapping system ( CARTO) in obtaining information on global dispersion of atrial repolarization and to evaluate the role of dispersion of repolarization in the genesis of paroxysmal atrial fibrillation ( PAF). Methods and results - Right atrial MAPs were recorded from 53 +/- 18 sites
We constructed hydrodynamical model atmospheres for mid M-type main-,as well as pre-main-sequence (PMS) objects. Despite the complex chemistry encountered in these cool atmospheres a reasonably accurate representation of the radiative transfer is possible, even in the context of time-dependent and three-dimensional models. The models provide detailed information about the morphology of M-type gran
3T3-L1 fibroblasts were induced to differentiate to 3T3-L1 adipocytes by dexamethasone, isobutyl-methylxanthine, and insulin. To study how differentiation affects extracellular matrix production, the accumulation of proteoglycans was studied by labeling the 3T3-L1 cells with [35S]sulphate for 24 h. The labeled proteoglycans were isolated from the medium and cell layer extracts by anion-exchange ch
The quality of the periacetabular bone might be an explanation for the increase in the rate of socket loosening seen radiographically in patients with rheumatoid arthritis as compared with patients with osteoarthrosis. Early implant micromotion, as measured by roentgen stereophotogrammetric analysis, is of predictive value with regard to long time retention. For uncemented porous sockets, the init
AIMS: To demonstrate a possible inter-atrial conduction delay in patients with lone paroxysmal atrial fibrillation (PAF) using 'unfiltered' signal-averaged P-wave ECG (PSAECG) and compare these results with those obtained with conventional filter settings. METHODS AND RESULTS: Twenty one patients with lone PAF and 20 healthy volunteers (control group) were enrolled in the study. An orthogonal lead
