Modulation Methods for Neutral-Point-Clamped Three-Level Inverter (2010)

Multilevel converters have seen an increasing popularity in the last years for medium- and high-voltage applications. The most popular has been the three-level neutral clamped converter and still research is going on to improve the control of it. This master thesis was a continuation of the specialization project fall 2009. The main topics of current thesis were to further investigate the DC-bus balancing issues, compare symmetrical (one sampling per triangular wave) and asymmetrical (sampling at the top and bottom of the triangular wave) modulation, derive current equations for Space Vector and Double-Signal, improve output voltage in overmodulation and be able to DC-bus balance, and to implement the methods in the laboratory. Models of the three-level converter were made in the specialization project in both PSCAD and SIMULINK and further studies of the DC-bus balance were also made in this master thesis. None of the methods showed problems to regulate the DC-bus voltage when there was different capacitor values and unsymmetrical load. A PI controller was introduced for Space Vector but it did not show better performance than a regular P regulator. Asymmetrical modulation showed a clearly better performance than symmetrical modulation when the switching frequency was low compared to the fundamental frequency, especially for Space Vector. The 1st harmonic line-to-line voltage was closer to the wanted value and the THDi was significantly lower. Simulations also showed that the THDi can vary significantly depending on at which angle the first sampling is done. This is most clear for asymmetrical Space Vector modulation, but also for the other cases this pattern occurs. By implementing an overmodulation algorithm the amplitude of the 1st harmonic output voltage was closer to what was desired. Simulations showed how important it was to have three phase sampling symmetry in overmodulation. By having a wrong switching frequency the line-to-line output voltage dropped down to 2.06 when operating in six-step, when the wanted output value should be 2.205. Hence there is a quite large mismatch and the converter is sensitive to the switching frequency when it is operating in the higher modulation area. The balancing algorithm introduced for overmodulation is able to remove an initial offset without a notable change the 1st harmonic output. Both Space Vector and Double-Signal were tested in the laboratory with two separated DC-sources. Asymmetrical and Symmetrical modulation were tested and so was also overmodulation. The laboratory results confirmed the simulated results, but since the switching was not synchronized in the laboratory, some errors occurred.
Cloning of the RNA8 gene of Saccharomyces cerevisiae, detection of the RNA8 protein, and demonstration that it is essential for nuclear pre-mRNA splicing. (1988)

Strains of Saccharomyces cerevisiae that bear the temperature-sensitive mutation rna8-1 are defective in nuclear pre-mRNA splicing at the restrictive temperature (36 degrees C), suggesting that the RNA8 gene encodes a component of the splicing machinery. The RNA8 gene was cloned by complementation of the temperature-sensitive growth defect of an rna8-1 mutant strain. Integrative transformation and gene disruption experiments confirmed the identity of the cloned DNA and demonstrated that the RNA8 gene encodes an essential function. The RNA8 gene was shown to be represented once per S. cerevisiae haploid genome and to encode a low-abundance transcript of approximately 7.4 kilobases. By using antisera raised against beta-galactosidase-RNA8 fusion proteins, the RNA8 gene product was identified in S. cerevisiae cell extracts as a low-abundance protein of approximately 260 kilodaltons. Immunodepletion of the RNA8 protein specifically abolished the activity of S. cerevisiae in vitro splicing extracts, confirming that RNA8 plays an essential role in splicing.

Determinants of quality of life in patients with incurable cancer (2020)

The current findings indicate that QoL is determined (at least in part) by WL, ECOG-PS, and the systemic inflammatory response in patients with advanced cancer. Identifying early predictors of poor QoL may allow the identification of patients who may benefit from early referral to palliative and supportive care, which has been shown to improve QoL.
Active Mobility of the Extremities in Older Subjects (1984)

The purposes of this study were to expand the data base of active range of motion (ROM) in the upper and lower extremities of older persons measured by goniometry and to determine if differences exist related to age, sex, and physical activity. Active ROM was measured with a clinical goniometer in 28 joint motions of the upper and lower extremities of the right side in 60 older subjects. Thirty men and 30 women were equally divided in two age groups of 60 to 69 and 75 to 84 years of age. Multivariate analysis of variance showed no significant differences in ROM that were attributable to sex and age. In univariate tests, however, 12 motions were significantly different (p less than .05) between the sexes, but only in 4 motions was the difference greater than intertester error. Physical activity, as assessed by a questionnaire and a rating scale, was not related to specific changes of joint range. Within the older subjects, however, a significant relationship between ROM and age or ROM and physical activity cannot be assumed. These results suggest that a data base of normative values is needed for older individuals.
Reduction of crystalline iron(III) oxyhydroxides using hydroquinone: Influence of phase and particle size (2005)

Iron oxides and oxyhydroxides are common and important materials in the environment, and they strongly impact the biogeochemical cycle of iron and other species at the Earth's surface. These materials commonly occur as nanoparticles in the 3–10 nm size range. This paper presents quantitative results demonstrating that iron oxide reactivity is particle size dependent. The rate and extent of the reductive dissolution of iron oxyhydroxide nanoparticles by hydroquinone in batch experiments were measured as a function of particle identity, particle loading, and hydroquinone concentration. Rates were normalized to surface areas determined by both transmission electron microscopy and Braunauer-Emmett-Teller surface. Results show that surface-area-normalized rates of reductive dissolution are fastest (by as much as 100 times) in experiments using six-line ferrihydrite versus goethite. Furthermore, the surface-area-normalized rates for 4 nm ferrihydrite nanoparticles are up to 20 times faster than the rates for 6 nm ferrihydrite nanoparticles, and the surface-area-normalized rates for 5 × 64 nm goethite nanoparticles are up to two times faster than the rates for 22 × 367 nm goethite nanoparticles.

Urinary amino-terminal propeptide of type III procollagen (PIIINP) as a marker of interstitial fibrosis in renal transplant recipients (2003)

These findings show that the urinary PIIINP-to-creatinine ratio reflects the ongoing fibrotic processes in the kidney. Tubular epithelial cell injury may initiate the fibrotic processes, and elevated concentrations of urinary TGF-beta 1 and alpha(1)M may associate with the increased production and deposition of collagen type III in the graft. We conclude that measurements of urinary excretion of PIIINP can be used as an early noninvasive indicator of renal fibrosis after kidney transplantation.
The microbiome in wound repair and tissue fibrosis (2012)

Bacterial colonization occurs in all wounds, chronic or acute, and the break in epithelium integrity that defines a wound impairs the forces that shape and constrain the microbiome at that site. This review highlights the interactions between bacterial communities in the wound and the ultimate resolution of the wound or development of fibrotic lesions. Chronic wounds support complex microbial communities comprising a wide variety of bacterial phyla, genera, and species, including some fastidious anaerobic bacteria not identified using culture-based methods. Thus, the complexity of bacterial communities in wounds has historically been underestimated. There are a number of intriguing possibilities to explain these results that may also provide novel insights into changes and adaptation of bacterial metabolic networks in inflamed and wounded mucosa, including the critical role of biofilm formation. It is well accepted that the heightened state of activation of host cells in a wound that is driven by the microbiota can certainly lead to detrimental effects on wound regeneration, but the microbiota of the wound may also have beneficial effects on wound healing. Studies in experimental systems have clearly demonstrated a beneficial effect for members of the gut microbiota on regulation of systemic inflammation, which could also impact wound healing at sites outside the gastrointestinal tract. The utilization of culture-independent microbiology to characterize the microbiome of wounds and surrounding mucosa has raised many intriguing questions regarding previously held notions about the cause and effect relationships between bacterial colonization and wound repair and mechanisms involved in this symbiotic relationship.
Use of the IELTS General Training module in technical and vocational tertiary institutions: A case study from Aotearoa New Zealand (2008)

Technical and vocational courses form a rapidly growing part of the tertiary environment in Aotearoa New Zealand. This area presents opportunities for tertiary education providers focusing on international students who do not have the academic ability for, or interest in, degree-level study, or who are studying niche subjects. One of the intended purposes of the General Training module of IELTS is as a test for students entering such non-degree level education programs. This project explored the following aspects of the use of the General Training module in the technical and vocational sector: the programs for which it is used, the extent to which it predicts success in the programs, other language-related factors involved in success, and student and staff perceptions of the Test. The project was a case study of all available institutions offering technical and vocational courses in one city. Eight institutions were investigated, with subject areas as varied as engineering, performance arts and aviation. The institutions ranged from large public providers with over 30,000 students (1300 international students) to small private providers with fewer than 20 students (all international). In-depth interviews were also carried out with 16 staff and 14 students. The study found that the General Training module was not well-known by students or staff in technical and vocational tertiary institutions in Aotearoa New Zealand, and few people had personal knowledge or experience of the Test. This was influenced by: the sector being extremely fluid, affecting institutional knowledge; student transfers from degrees to vocational programs; confusion about student visa requirements; institutions not insisting on English language requirements; and institutions setting their own tests. In addition, some institutions had changed their entry requirements from the General Training to the Academic module. The main recommendation from the study is that IELTS should work on raising awareness about the General Training module as an option for technical and vocational program entry requirements among students, tertiary providers and industry training organisations. The constant changes in the sector mean that this awareness raising needs to be an ongoing task.
The prevalence and clinical course of functional dyspepsia (2004)

Functional dyspepsia is prevalent world-wide, but the prognosis remains poorly defined. There is a need for population-based studies to examine the prevalence and clinical course of documented functional dyspepsia.
Ellipsis and Movement in the Syntax of Whether/Q...or Questions (2002)

Characterization of the Role of Very Late Expression Factor 1 in Baculovirus Capsid Structure and DNA Processing (2006)

Very late expression factor 1 (VLF-1) of Autographa californica multiple nucleopolyhedrovirus is a putative tyrosine recombinase and is required for both very late gene expression and budded virus production. In this report, we show that a vlf-1 knockout bacmid was able to synthesize viral DNA at levels similar to that detected for a gp64 knockout bacmid that served as a noninfectious control virus. Additionally, analysis of replicated bacmid DNA by field-inversion gel electrophoresis indicated that VLF-1 is not required for synthesizing high-molecular-weight intermediates that could be resolved into unit-length genomes when cut at a unique restriction site. However, immunoelectron microscopic analysis revealed that in cells transfected with a vlf-1 knockout bacmid, aberrant tubular structures containing the capsid protein vp39 were observed, suggesting that this virus construct was defective in producing mature capsids. In contrast, rescuing the vlf-1 knockout bacmid construct with a copy of VLF-1 that carries a mutation of a highly conserved tyrosine (Y355F) was sufficient to restore the production of nucleocapsids with a normal appearance, but not infectious virus production. Furthermore, the results of a DNase I protection assay indicated that the DNA packaging efficiency of the VLF-1(Y355F) virus construct was similar to that of the gp64 knockout control. Finally, a recombinant virus containing a functional hemagglutinin epitope-tagged version of VLF-1 was constructed to investigate the association of VLF-1 with the nucleocapsid. Analysis by immunoelectron microscopy of Sf-9 cells infected with this virus showed that VLF-1 localized to an end region of the nucleocapsid. Collectively, these results indicate that VLF-1 is required for normal capsid assembly and serves an essential function during the final stages of the DNA packaging process.
Linear acoustic echo cancellation using deep neural networks and convex reconstruction of incomplete transfer function (2017)

Linear acoustic path estimation for acoustic echo cancellation is difficult during periods where the near-end signal (speech) is active. In this paper, we assume that the impulse response is sparse. There are many algorithms that solve the problem of estimating sparse impulse response in the time domain. In this paper, we propose algorithms working in the time-frequency domain. In our approach, it is assumed that the respective transfer function can be estimated only for those frequencies where the near-end signal is not active. First, a deep neural network trained on mixed signals is used to detect the activity of the near-end signal. In frequencies where no activity is detected, the acoustic transfer function is estimated using conventional frequency domain least squares. This results in an incomplete transfer function (ITF) estimate. The completion is done through finding the sparsest representation of the ITF in the time domain. This can be done adaptively using the soft-threshold function, which is applied in the time domain. To achieve improved accuracy, oversampling can be used.

Ground roll suppression by the stackarray (1988)

For 2-D common‐midpoint (CMP) seismic data acquisition, ground roll can be highly attenuated and, under ideal circumstances, virtually eliminated from the stacked data if care is taken to adjust the field geometry so that the long array formed by summing the traces of a CMP gather (i.e., the stackarray) is continuous and evenly weighted. In this paper, we use synthetic field data to quantify the improvement in signal‐to‐noise ratio that can be achieved by the stackarray and to determine if such processing steps as normal moveout (NMO) correction affect the stackarray’s effectiveness. We demonstrate that, while the beneficial effects of the stackarray are mitigated somewhat by NMO correction, source‐receiver coupling variations, and static corrections, acquisition geometries that result in a discontinuous or unevenly weighted stackarray have a much more pronounced negative effect. We also compare real field data recorded with geometries that do and do not satisfy the stackarray criterion. On the basis of b...
Genetic and Developmental Control of Multiple Forms of l-Glycerol 3-Phosphate Dehydrogenase (1974)

Abstract A molecular form of l-glycerol 3-phosphate dehydrogenase (EC 1.1.1.8) is found during early stages of mouse development that differs in several respects from the major form found in adult tissues. This early or embryonic form can be separated from the major adult form by ion exchange chromatography, it is more sensitive to thermal denaturation, and has lower Km values for dihydroxyacetone phosphate and lglycerol-3-P. The embryonic form is found in brain up to 9 days of age, in the carcass up to 16 days of gestation, and in mouse teratoma; however, it has not been detected in fetal liver as early as 13 days of gestation nor in fetal kidney. The embryonic form of l-glycerol-3-P dehydrogenase is probably coded for by a genetic locus distinct from the locus for the adult enzyme, for although there is a difference in the rate of thermal denaturation for the enzyme from adult tissues of BALB/cBy and C57BL/6J mice, no strain-dependent differences are observed with the embryonic enzyme.
Altered effect of the Valsalva maneuver on left ventricular volume in patients with cardiomyopathy. (1985)

The failure of the blood pressure to fall during the late strain pase of the Valsalva maneuver in patients with heart failure may result from the left ventricle operating on a flat portion of its function curve or from maintenance of left ventricular volume despite decreased systemic venous return. To test these possibilities, we studied the effect of the Valsalva maneuver (40 cm H2O for 15 sec) on left ventricular volume in 12 normal subjects with a mean left ventricular ejection fraction of 0.65 +/- 0.07 (+/- SD) and in eight patients with nonischemic cardiomyopathy, evidence of pulmonary congestion, and a mean left ventricular ejection fraction of 0.23 +/- 0.09. Left ventricular volume and right ventricular area were determined by apical two-dimensional echocardiography. In both groups the right ventricular end-diastolic area decreased during the late strain phase of the Valsalva maneuver. In normal subjects it decreased from 9.3 +/- 1.5 to 5.6 +/- 1.6 cm2 (p less than .001) and in patients it decreased from 13 +/- 2.2 to 10 +/- 2.9 cm2 (p less than .001). In normal subjects, left ventricular end-diastolic volume decreased from the control level during the Valsalva maneuver, and this was apparent in both the four-chamber (96 +/- 21 to 68 +/- 18 ml, p less than .01) and two-chamber views (97 +/- 15 to 56 +/- 20 ml, p less than .01). In the patients, left ventricular end-diastolic volume was not significantly different from control in either view (199 +/- 70 to 195 +/- 78 and 214 +/- 77 to 218 +/- 86 ml, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
Fair Resource Allocation in OFDMA Two-Hop Cooperative Relaying Cellular Networks (2009)

This paper discusses on the fair resource allocation in OFDMA two-hop cooperative relaying cellular networks which consist of a single base station (BS), dedicated fixed relay stations (RSs) and user stations (USs). By assuming the relay strategy employed on each subcarrier is adaptively selected among direct transmission, amplify-and-forward (AF) and decode-and-forward (DF) according to different channel conditions, we formulate a fair subcarrier assignment, relay station and relay strategy selection problem with QoS constraints in terms of user's minimum rate requirement. The formulated problem is a binary integer programming (BIP) problem which is NP-complete, so a simple suboptimal algorithm is proposed to manage the network resources. Simulations demonstrate the proposed algorithm obtains near optimal solution with low complexity and achieves a good tradeoff between the overall system performance and the fairness among users.
