This paper presents a QVCO and divider for a 28 GHz SiGe PLL. It was designed in a SiGe process with fT= 200 GHz. The PLL is intended to be used for beam steering in an 81-86 GHz E-band transmitter. Phase control is implemented by programmable current injection into the loop filter. The simulations in Spectre use a layout extracted view with parasitics for the QVCO and the frequency divider and an
Legacy streamer data and newer 3D ocean-bottom-cable data are cross-matched and analysed for time-lapse analysis of geomechanical changes due to production in the Valhall Field. The issues relating to time-lapse analysis using two such distinctly different data sets are addressed to provide an optimal cross-matching workflow that includes 3D warping. Additionally an assessment of the differences b
In recent years, dynamical modelling has been provided with a range of breakthrough methods to perform exact Bayesian inference. However, it is often computationally unfeasible to apply exact statistical methodologies in the context of large data sets and complex models. This paper considers a nonlinear stochastic differential equation model observed with correlated measurement errors and an appli
Objectives. Cancer and type 2 diabetes (T2D) are two common diseases that may share risk factors. We aimed at determining subsequent cancer risks in patients hospitalized for T2D in Sweden. Methods. T2D patients were obtained from the nationwide Hospital Discharge Register; cancers were recorded from the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for cancer follo
Akt (also known as PKB) is a survival kinase frequently up-regulated in cancer; three isoforms of Akt exist, and among them Akt1 and Akt2 are the most widely and highly expressed. They share the same structure and activation mechanism and have many overlapping functions; nevertheless isoform-specific roles and substrates have been reported, which are expected to rely on sequence diversities. In pa
We examine the applicability of the extended law of corresponding states (ELCS) to equilibrium and non equilibrium features of the state diagram of the globular protein lysozyme. We provide compelling evidence that the ELCS correctly reproduces the location of the binodal for different ionic strengths, but fails in describing the location of the arrest line. We subsequently use Mode Coupling Theor
The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable prosthesis-patient mismatch (PPM). PPM has been reported to be detrimental for survival and symptom resolution main
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.
To increase the overall ethanol yield from softwood, the steam pretreatment stage can be carried out in two steps. The two-step pretreatment process was evaluated from a techno-economic standpoint and compared with the one-step pretreatment process. The production plants considered were designed to utilize spruce as raw material and have a capacity of 200 000 tons/year. The two-step process result
Study Design. The study is an observational cohort study. Objectives. To determine the incidence and the long-term outcome of thoracic or lumbar vertebral fractures in children. Summary of Background Data. The incidence of vertebral fractures in children is described as rare and the outcome as favorable. However, no studies evaluate the clinical and radiographic long-term outcome and if a fracture
A series of field studies at cold workplaces were initiated. This paper deals with the study at a telecommunication company and the main attention is paid to the thermal responses of the feet and footwear performance. The study was carried out in February. Eight male workers were the subjects. They were selected among volunteers who carried out various jobs on high masts on four different days. Th
Apolipoprotein ( apo) M is a novel apolipoprotein belonging to the lipocalin protein superfamily, i.e. proteins binding small lipophilic compounds. Like other apolipoproteins, it is expressed in hepatocytes and secreted into plasma where it associates with high-density lipoprotein particles. In addition, apoM is expressed at high levels in the kidney tubule cells. In this study, we show that the m
The overall aim of this thesis was to describe changes in the prevalence and severity of periodontal diseases and to identify risk factors for severe periodontal disease in adults living in Jönköping County, Sweden, by analysing the cross-sectional, epidemiological studies that had been carried out in the city of Jönköping in 1973, 1983, and 1993. Individuals were randomly selected from the follow
A system for the photodynamic laser treatment of massive tumors that employs multiple optical fibers to be inserted into the tumor mass is described. The light flux through the tumor can be assessed by use of the individual fibers both as transmitters and as receivers. With a computer model that describes the diffusive light propagation, optical dosimetry is under development, The system has been
The objective of this study was to design and experimentally examine a sampling method for high-temperature aerosols from biomass combustion, in which nucleation and condensation from fly ash forming vapors is controlled. The sampling method includes a high-temperature probe in which the hot gas is diluted and then cooled. Laboratory results from sampling a model aerosol with known concentrations
Embryonic genome activation (EGA) is the first major step towards successful initiation of preimplantation development, which culminates in the formation of implantation-competent embryos. EGA occurs at species-specific embryonic cell stages. In the present work, EGA was identified for buffalo embryos by studying the development rate of embryos in normal as well as imposed transcription block cond
