description: A new method has been developed at the Siberian Research Institute of Metrology (SNIIM) for highly accurate prediction of UT1 and Pole coordinates. The method is based on construction of a general polyharmonic model of the variations of the Earth rotation parameters using all the data available for the last 80-100 years, and modified autoregression technique. In this presentation, a detailed comparison was made of real-time UT1 predictions computed making use of this method in 2006-2010 with simultaneous predictions computed at the International Earth Rotation and Reference Systems Service (IERS). Obtained results have shown that proposed method provides better accuracy at different prediction lengths.

description: Quantum probes are atomic sized devices mapping information of their environment to quantum-mechanical states. By improving measurements and at the same time minimizing perturbation of the environment, they form a central asset for quantum technologies. We realize spin-based quantum probes by immersing individual Cs atoms into an ultracold Rb bath. Controlling inelastic spin-exchange processes between the probe and bath allows us to map motional and thermal information onto quantum-spin states. We show that the steady-state spin population is well suited for absolute thermometry, reducing temperature measurements to detection of quantum-spin distributions. Moreover, we find that the information gain per inelastic collision can be maximized by accessing the nonequilibrium spin dynamic. Keeping the motional degree of freedom thermalized, individual spin-exchange collisions yield information about the gas quantum by quantum. We find that the sensitivity of this nonequilibrium quantum probing effectively beats the steady-state Cramér-Rao limit by almost an order of magnitude, while reducing the perturbation of the bath to only three quanta of angular momentum. Our work paves the way for local probing of quantum systems at the Heisenberg limit, and moreover, for optimizing measurement strategies via control of nonequilibrium dynamics. © 2020 authors.

description: Obstructions of the Fallopian tube represent one of the most common reasons for an unfulfilled desire to have children. Microstent technology opens up new therapeutic possibilities to restore the natural lumen of the Fallopian tube within a single treatment. Within the current work we developed a self-expandable biodegradable microstent for gynecological applications. Based on a novel microstent design, prototypes were manufactured from poly-L-lactide tubing by means of fs-laser cutting. Microstent prototypes were characterized morphologically by means of scanning electron microscopy and biaxial laser scanning. As manufactured, a microstents outside diameter of about 2.3 mm and a strut thickness/width of about 114 µm/103 µm was measured. Mechanical characterization of microstents included bending as well as crimping and release behavior. After crimping to a minimum diameter of 0.8 mm and consecutive release, a microstent recovery to a diameter of 1.8 mm was found. Therefore, proof-of-concept for the self-expandable microstent could be successfully provided. © 2020 by Walter de Gruyter Berlin/Boston 2020.

description: The neighborhood effect, a crucial component of the cellular automata (CA) model, has been extensively studied. However, no research has yet investigated CA modeling based on varying neighborhood sensitivity for different land use types. In this study, we combined the First Law of Geography and various sensitivity of different land use types to introduce two novel types of neighborhoods for CA modeling: adaptive homogeneous neighborhood (AHN) and adaptive spatially heterogeneous neighborhood (ASHN). By applying this approach to Beijing, Wuhan, and the Pearl River Delta, we demonstrated the implementation process and conduct land use change simulations from 2000 to 2010 as the calibration period and from 2010 to 2020 as the validation period. Our findings revealed that the AHN-CA and ASHN-CA models exhibit higher accuracy than homogeneous neighborhoods cellular automata (HN-CA) and provide more detailed landscape patterns.

description: Background: Child vaccination is one of the public health interventions that are responsible for
the relatively low child morbidity and mortality in developed nations compared to the developing
world. We carried out this study to examine the association between mothers' use of traditional
healer services and vaccination among Haitian children. Our hypothesis was that children whose
mothers used the services of traditional healers were less likely to be vaccinated compared to
children whose mothers did not use the services of traditional healers.
Methods: A two-stage stratified sampling method was used to select 720 mothers from the
population of Pont-Sonde, Haiti. Of these mothers, 691 (96%) completed the survey by responding
to a standardized questionnaire on vaccination giving unadjusted odds ratios (OR) and adjusted
odds ratios (AOR) and 95% confidence intervals (CI) and use of traditional healers. Bivariate and
multivariate logistic regression analyses were performed to estimate the effect of explanatory
variables on vaccination (the main outcome).
Results: Mother's use of traditional healer services was negatively associated with vaccination after
controlling for maternal age, education, religion, and distance from the nearest health care facility.
For those children whose mothers often or always used the services of traditional healers, we
found a 53% decrease in the odds of vaccination (AOR = 0.47; 95% CI [0.27, 0.83]) compared
against children whose mothers never used the services of the traditional healers. There were
negative associations between practice of Vodou and vaccination (AOR = 0.56; 95% CI [0.35,
0.92]), and distance from the nearest health care service facility and vaccination (AOR = 0.53; 95%
CI [0.29, 0.97] and AOR = 0.34; 95% CI [0.20, 0.59] at 46–60 and more than 60 minutes walk time,
respectively).
Conclusion: We found that mother's use of traditional healer services was negatively associated
with vaccination of Haitian children. Findings from this study underscore the potential to enlist the
support of traditional healers in promoting child health by educating, mentoring them (the
traditional healers) in supporting vaccination efforts.

description: Measuring the spectral irradiance of solar radiation is required in many fields of science and technology. In this work, we present an in-depth discussion of the measuring procedure and required corrections for such measurements. We also describe our measurement uncertainty analysis, which is based on a Monte-Carlo procedure in accordance with the Guide to the expression of uncertainty in measurement (JCGM, Paris, 2008). For this purpose, fifteen uncertainty sources are identified, analyzed and described analytically. As a specific application example, we describe the instrumentation and procedure for determining the spectral irradiance of a solar simulator at the ISO/IEC 17 025 accredited solar cell calibration laboratory ISFH CalTeC and the corresponding measurement uncertainty analysis. Moreover, we provide a Python implementation for this calculation along with the paper. We show that for state-of-the-art instrumentation, significant uncertainty contributions arise from the reference lamp (primary calibration standard), stray light and signal-to-noise ratio. If sharp spectral features are present (which is common, e.g. for Xenon lamps), spectral bandwidth and wavelength uncertainty also contribute significantly to the overall uncertainty. © 2020 BIPM & IOP Publishing Ltd

description: Abstract Background In rheumatoid arthritis (RA), cardiovascular risk is associated with paradoxical reductions in total cholesterol, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C). Concentrations of small LDL (LDL-P) and HDL (HDL-P) particles are also reduced with increased inflammation and disease activity in RA patients. Here we sought to identify which measure(s) of inflammation, disease activity and cardiometabolic risk contribute most to the RA-associated lipoprotein profile. Methods NMR lipoprotein measurements were obtained for individuals with RA (n = 50) and age-, gender-, and body mass index (BMI)-matched controls (n = 39). Groups were compared using 39 matched pairs with 11 additional subjects used in RA only analyses. Among RA patients, relationships were determined for lipoprotein parameters with measures of disease activity, disability, pain, inflammation, body composition, insulin sensitivity and exercise. Percentage of time spent in basal activity (<1 metabolic equivalent) and exercise (≥3 metabolic equivalents) were objectively-determined. Results Subjects with RA had fewer total and small LDL-P as well as larger LDL and HDL size (P < 0.05). Among RA patients, pain and disability were associated with fewer small HDL-P (P < 0.05), while interleukin (IL)-6, IL-18, and TNF-α were associated with LDL size (P < 0.05). BMI, waist circumference, abdominal visceral adiposity and insulin resistance were associated with more total and small LDL-P, fewer large HDL-P, and a reduction in HDL size (P < 0.05). Most similar to the RA lipoprotein profile, more basal activity (minimal physical activity) and less exercise time were associated with fewer small LDL-P and total and small HDL-P (P < 0.05). Conclusions The RA-associated lipoprotein profile is associated with a lack of physical activity. As this was a cross-sectional investigation and not an intervention and was performed from 2008–13, this study was not registered in clinicaltrials.gov.

description: In this paper, strain gradient elasticity formulation for analysis of FG (Functionally Graded) micro-cylinders is presented. The material properties are assumed to obey a power law in radial direction. The governing differential equation is derived as a fourth order ODE. A power series solution for stresses and displacements in FG micro-cylinders subjected to internal and external pressures is obtained. Numerical examples are presented to study the effect of the characteristic length parameter and FG power index on the displacement field and stress distribution in FG cylinders. It is shown that the characteristic length parameter has a considerable effect on the stress distribution of FG micro-cylinders. Also, increasing material length parameter leads to decrease of the maximum radial and tangential stresses in the cylinder. Furthermore, it is shown that the FG power index has a significant effect on the maximum radial and tangential stresses.

description: Abstract Background To illustrate the 10-year risks of urinary adverse events (UAEs) among men diagnosed with prostate cancer and treated with different types of therapy, accounting for the competing risk of death. Methods Prostate cancer is the second most common malignancy among adult males in the United States. Few studies have reported the long-term post-treatment risk of UAEs and those that have, have not appropriately accounted for competing deaths. This paper conducts an inverse probability of treatment (IPT) weighted competing risks analysis to estimate the effects of different prostate cancer treatments on the risk of UAE, using a matched-cohort of prostate cancer/non-cancer control patients from the Surveillance, Epidemiology and End Results (SEER) Medicare database. Results Study dataset included men age 66 years or older that are 83% white and had a median follow-up time of 4.14 years. Patients that underwent combination radical prostatectomy and external beam radiotherapy experienced the highest risk of UAE (IPT-weighted competing risks: HR 3.65 with 95% CI (3.28, 4.07); 10-yr. cumulative incidence = 36.5%). Conclusions Findings suggest that IPT-weighted competing risks analysis provides an accurate estimator of the cumulative incidence of UAE taking into account the competing deaths as well as measured confounding bias.

description: An der Basis der Eisschilde, die Grönland und die Antarktis bedecken, finden sich Kanalstrukturen. Sie stellen einen wichtigen Teil des subglazialen hydrologischen Systems der Eisschilde und der Schelfeise dar. Mithilfe eines numerischen Modells der viskoelastischen Rheologie von Eis wird die zeitliche Entwicklung dieser Strukturen in dieser Arbeit untersucht. Ein Abfall des Wasserdrucks innerhalb eines subglazialen Kanals an der Basis eines gegründeten Gletschers führt zu einer Verringerung seiner Querschnittsfläche. Die Geschwindigkeit, mit der diese Verringerung erfolgt, hängt wesentlich vom Wasserdruck und der initialen Form des Kanals ab. Ein Teil der Querschnittsflächenverringerung erfolgt instantan durch die elastische Deformation des viskoelastischen Eises. Am Support-Force Gletscher in der Westantarktis findet sich ein Schmelzkanal an der Unterseite des Filchner Schelfeises. Aufgrund des Schmelzkanals ist das hydrostatische Gleichgewicht des Schelfeises gestört. Der Kanal beginnt sich durch ein Fließen des Eises zu schließen. Die Geschwindigkeit dieses Eisflusses wird wesentlich durch die nichtlineare Viskosität des Eises beeinflusst. Basales Schmelzen und oberflächliche Akkumulation stellen zusätzliche Einflussfaktoren auf die Entwicklung des Eiskörpers dar. Der elastische Anteil der viskoelastischen Deformation von Eis trägt in signifikantem Maß zur Verringerung der Querschnittsfläche subglazialer Kanäle großer Breite und geringer Höhe bei. In der Reaktion des Schelfeises auf eine zyklische Belastung spiegelt sich die viskoelastische Rheologie des Eises ebenfalls wider. Zukünftige Betrachtungen der untersuchten Strukturen mithilfe numerischer Modelle sollten daher die viskoelastischen Materialeigenschaften des Eises mit berücksichtigen.

description: Dynamic spectrum management (DSM) has been recognized as a key technology to significantly improve the performance of digital subscriber line (DSL) broadband access networks. The basic concept of DSM is to coordinate transmission over multiple DSL lines so as to mitigate the impact of crosstalk interference amongst them. Many algorithms have been proposed to tackle the nonconvex optimization problems appearing in DSM, almost all of them relying on a standard subgradient based dual decomposition approach. In practice however, this approach is often found to lead to extremely slow convergence or even no convergence at all, one of the reasons being the very difficult tuning of the stepsize parameters. In this paper we propose a novel improved dual decomposition approach inspired by recent advances in mathematical programming. It uses a smoothing technique for the Lagrangian combined with an optimal gradient based scheme for updating the Lagrange multipliers. The stepsize parameters are furthermore selected optimally removing the need for a tuning strategy. With this approach we show how the convergence of current state-of-the-art DSM algorithms based on iterative convex approximations (SCALE, CA-DSB) can be improved by one order of magnitude. Furthermore we apply the improved dual decomposition approach to other DSM algorithms (OSB, ISB, ASB, (MS)-DSB, MIW) and propose further improvements to obtain fast and robust DSM algorithms. Finally, we demonstrate the effectiveness of the improved dual decomposition approach for a number of realistic multi-user DSL scenarios.

description: Abstract: Out of a single Bose-Einstein condensate (BEC), we create two simultaneous interferometers, as employed for the differentiation between rotations and accelerations. Our method exploits the precise motion control of BECs combined with the precise momentum transfer by double Bragg diffraction for interferometry. In this way, the scheme avoids the complexity of two BEC sources and can be readily extended to a six-axis quantum inertial measurement unit.

description: Der Wald im Nationalpark Harz befindet sich derzeit im Wandel. Globale Erwärmung, Windwürfe und anfällige Fichtenreinbestände begünstigen die Ausbreitung des Borkenkäfers. Auf großer Fläche wird der Käfer im Nationalpark nicht bekämpft, denn hier greift der Prozessschutz. Die Natur darf sich nach ihren eigenen Gesetzen entwickeln. Dies führt zu großen Totholzflächen, in denen in den darauffolgenden Jahren eine Naturverjüngung stattfindet. Sie bilden einen Kontrast zum gewohnten Waldbild und sind Ursache eines größeren Konfliktes. Teil dessen sind Befürchtungen über reduzierte Touristenzahlen. Der Harz ist seit Jahrhunderten eine beliebte Freizeit- und Tourismusregion und der Naturtourismus nimmt eine bedeutende Rolle in der regionalen Wirtschaft ein. Die Ergebnisse aus Literaturrecherche und empirischer Untersuchung zeigen, dass die Flächen von den Touristen weitestgehend mit positiven Assoziationen verbunden werden. Zudem haben sowohl die Gäste als auch die lokalen Tourismusakteure eine positive Einstellung gegenüber der Nationalparkphilosophie „Natur Natur sein lassen“. Eine negative Beeinflussung der Besucherzahlen durch die Totholz- und Naturverjüngungsflächen im Nationalpark Harz ist nicht zu befürchten. Um diese Wahrnehmungen und Einstellungen zu bestärken, sind intensive Aufklärung und Information essentiell. Weiterhin ist zur Lösung des übergeordneten Konfliktes eine stärkere Auseinandersetzung mit verschiedenen Interessensgruppen zu empfehlen.

description: The aim of this bachelor thesis is to give an overview of the implementation of the minimum wage in the transport sector five years after the introduction of the minimum wage. In collaboration with R V Insurance, KRAVAG-LOGISTIC and the Institute for logistics law & risk management, this work is intended to close research gaps in the still slender literature and provide recommendations for action for companies, associations and legislators. The focus is on the strictness of monitoring of foreign transport companies in Germany and the resulting distortions in competition in the German transport sector. To this end, in addition to extensive literature and press research, several wide-ranging interviews were conducted with experts from the industry. Overall, a comparison of my empirical enquiries with my theoretical findings shows that Eastern European freight forwarders enjoy a competitive advantage on German roads due to blatant differences in minimum wages in the European Union. In this way, nationwide breaches of the minimum wage law are being tolerated. Overall this has resulted in very interesting and meaningful outcomes. So, for example, a wage advantage of almost 100.000.000 a a year for foreign freight forwarders in German cabotage traffic or the fact that a Polish truck that operates cabotage in Germany would be able to drive about 180.000 kilometres without getting in a minimum wage control. But thata s just a small sample of all results. Five years after its introduction, the minimum wage law is still a much discussed and controversial topic in the transport industry. Even beyond the controls and competitive advantages of Eastern European freight forwarders, it is confronted with several problems, such as general contractor liability and extensive documentation obligations. You notice the problems in connection with the minimum wage law go far beyond the mere payment of the minimum wage. So ita s worth taking a look at this bachelor thesis in order on the one hand to gain some possible insights from my treatment of a hypothesis which has not yet been discussed in the literature in such a way, and on the other to get a completely new view on the minimum wage law in the German transport industry.

description: Abstract Background The Patient Reported Outcomes Measurement Information System 43-item short form (PROMIS-43) and the five-level EQ-5D (EQ-5D-5L) are recently developed measures of health-related quality of life (HRQL) that have potentially broad application in evaluating treatments and capturing burden of respiratory-related diseases. The aims of this study were: (1) to examine their psychometric properties in patients with chronic obstructive pulmonary disease (COPD), and (2) to identify dimensions of HRQL that differ and do not differ by lung function. Methods We conducted a multi-center, cross-sectional study (“COPD Outcomes-based Network for Clinical Effectiveness & Research Translation” [CONCERT]). We analyzed patients who met spirometric criteria for COPD, and completed EQ-5D-5L and PROMIS questionnaires. Disease severity was graded based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. Pulmonary function test, PROMIS-43, EQ-5D (index score and EQ-Visual Analog Scale [EQ-VAS]), six minute walk test (6MWT), and three dyspnea scales (mMRC, Borg, FACIT-Dyspnea) were administered. Validity and reliability of EQ-5D-5L and PROMIS-43 were examined, and differences in HRQL by GOLD grade were assessed. Results Data from 670 patients with COPD were analyzed (mean age 68.5 years; 58% male). More severe COPD was associated with more problems with mobility, self-care and usual activities (all p-values <0.01) according to EQ-5D-5L. Related domains on EQ-5D-5L, PROMIS and clinical measures were moderately (r = 0.30-0.49) to strongly (r ≥ 0.50) correlated. A statistically significant trend of decreasing HRQL with more severe lung functions was observed for EQ-5D-5L index scores, EQ-VAS scores, and PROMIS physical function and social roles. Conclusions Results supported the validity of EQ-5D-5L and PROMIS-43 in COPD patients, and indicate that physical function and social activities decrease with level of lung function by GOLD grade, but not pain, mental health, sleep or fatigue as reported by patients.

description: In dieser Masterarbeit erfolgt eine Auseinandersetzung mit der Adoption der Innovation Open Data in der deutschen öffentlichen Verwaltung. Anlass für die Untersuchung ist einerseits die Frage danach, warum die Ausbreitung von Open Data in Deutschland trotz potenzieller Vorteile und den von den politischen Instanzen vorgegeben Richtungssignalen in der Praxis bisher eher zurückhaltend stattgefunden hat. Und andererseits, wie eine weitergehende Akzeptanz und damit Ausbreitung der Idee von Open Data erfolgen, bzw. gefördert werden könnte. Im Zentrum des Interesses stehen die individuellen Innovationsentscheidungsprozesse von Adoptierenden in der öffentlichen Verwaltung. Darüber hinaus werden die Schlüsselakteure der Innovation Open Data und deren Einflussnahme auf die Innovationsentscheidungsprozesse fokussiert. Als theoretische Grundlage dieser Arbeit dient die Theorie der „Diffusion of Innovations“ sowie die aus der Innovationsforschung stammenden Konzepte der „Innovationschampions“ und der „Promotoren einer Innovation“. Die Arbeit ist als explorative Interviewstudie konzipiert, die eine möglichst breite Erfassung von Erfahrungswerten, Erklärungsansätzen sowie Handlungsempfehlungen von verwaltungsinternen- oder nahen Open-Data-Expert*innen zum Ziel hat. Insgesamt wurden 10 leitfadengestützte Expert*inneninterviews durchgeführt. Die Auswertung des erfassten Datenmaterials erfolgte mithilfe einer softwaregestützten inhaltlich-strukturierenden Inhaltsanalyse nach Udo Kuckartz. Es konnten zum einen vielfältige Erkenntnisse hinsichtlich ablehnender Haltungen, negativer Einstellungen sowie des Auftretens von Widerstand gegenüber der Innovation Open Data erfasst werden. Zum anderen konnte mit der Identifizierung von Handlungsbögen sowie der Erfassung und Strukturierung von Empfehlungen der befragten Expert*innen die Frage nach dem „Wie“ der weitergehenden Adoption des Prinzips der offenen Verwaltungsdaten in der öffentlichen Verwaltung ein Stück weit beantwortet werden.

description: Abstract Innovative research relating oceans and human health is advancing our understanding of disease-causing organisms in coastal ecosystems. Novel techniques are elucidating the loading, transport and fate of pathogens in coastal ecosystems, and identifying sources of contamination. This research is facilitating improved risk assessments for seafood consumers and those who use the oceans for recreation. A number of challenges still remain and define future directions of research and public policy. Sample processing and molecular detection techniques need to be advanced to allow rapid and specific identification of microbes of public health concern from complex environmental samples. Water quality standards need to be updated to more accurately reflect health risks and to provide managers with improved tools for decision-making. Greater discrimination of virulent versus harmless microbes is needed to identify environmental reservoirs of pathogens and factors leading to human infections. Investigations must include examination of microbial community dynamics that may be important from a human health perspective. Further research is needed to evaluate the ecology of non-enteric water-transmitted diseases. Sentinels should also be established and monitored, providing early warning of dangers to ecosystem health. Taken together, this effort will provide more reliable information about public health risks associated with beaches and seafood consumption, and how human activities can affect their exposure to disease-causing organisms from the oceans.

description: Die Arbeit wendet Jürgen Habermas' Theorie des kommunikativen Handelns auf das soziale Medium Facebook als Fallbeispiel für prägende digitale Kommunikationsstrukturen an. Phänomene digitaler Kommunikation wurden zuvor in erster Linie nur aus den Perspektiven von dessen Habilitationsschrift oder Diskursethik untersucht, welche eine Eignung digitaler Kommunikation für Diskurse und öffentliche Willensbildung suggerieren. Mit der umfassenden Rekonstruktion von Habermas' Hauptwerk stellt diese Arbeit jedoch fest, dass soziale Medien weder öffentlicher Willensbildung noch Diskursen oder kommunikativem Handeln allgemein eine sichere Grundlage bieten. Stattdessen schreitet die Kolonialisierung der Lebenswelt durch das wirtschaftliche und das administrative Subsystem hier durch eine von der Arbeit erfasste dreifache Mediatisierung von Kommunikation beschleunigt voran. Die Monetarisierung von Nutzer*innendaten, die mediale Steuerung von Kommunikation durch Algorithmen und der dadurch etablierte Wettbewerb um Aufmerksamkeit zwischen den Nutzer*innen sozialer Medien bewirken, dass sie einander zunehmend eher als zweckrationale Akteure, denn als Mitbewohner der selben Lebenswelt begegnen. Insofern Nutzer*innen durch Werbung permanent als Konsumierende angesprochen sind, ihr online ständig aufgezeichnetes Verhalten für den Arbeitsmarkt oder für die Qualifikation zu sozial-staatlichen Versorgungsangeboten anpassen oder um Aufmerksamkeit in einem durch digitale Massenmedien konstant gehaltenen politischen Meinungskampf ringen, können sie miteinander keine lebensweltliche Verständigung mehr bewältigen.

description: Im Rahmen dieser Bachelorarbeit wird der folgenden Forschungsfrage theoretisch nachgegangen: "Anhand welcher Kriterien können Bilderbücher für einen inklusiven Literaturunterricht in der Primarstufe ausgewählt werden?" Dabei wird zunächst die Notwendigkeit eines Kriterienkataloges für die schulische Praxis der Primarstufe dargelegt. Nach der Definition eines Inklusionsverständnisses werden die Ansätze von Sabine Pfäfflin, Simone Hell und Jochen Hering dahingehend überprüft, welche Kriterien zur Auswahl für Bilderbücher für inklusive Settings geeignet erscheinen. Darauf baut der im Folgenden entwickelte Kriterienkatalog auf, der an exemplarischen Bilderbuchbetrachtungen überprüft und konkretisiert und schließlich an zwei Bilderbüchern zur Anwendung gebracht wird. Anhand der ausgefüllten Kriterienkataloge werden Potenziale der Bilderbücher hinsichtlich ausgewählter Grundkompetenzen literarischen Verstehens, anhand des BOLIVE-Modells, dargestellt. Zuletzt werden, nach einer kritischen Reflexion des Kriterienkataloges, die Erkenntnisse zusammenfasst und Forschungsdesiderata aufzeigt.

description: We present results of a search for periodic gravitational wave signals with frequencies between 20 and 400 Hz from the neutron star in the supernova remnant G347.3-0.5 using LIGO O2 public data. The search is deployed on the volunteer computing project Einstein@Home, with thousands of participants donating compute cycles to make this endeavour possible. We find no significant signal candidate and set the most constraining upper limits to date on the amplitude of gravitational wave signals from the target, corresponding to deformations below 10-6 in a large part of the band. At the frequency of best strain sensitivity, near 166 Hz, we set 90% confidence upper limits on the gravitational wave intrinsic amplitude of . Over most of the frequency range our upper limits are a factor of 20 smaller than the indirect age-based upper limit. © 2022. The Author(s). Published by the American Astronomical Society..

description: Ein Modell zur Simulation der Elektrostatik in der Mesosphäre unter einem Strom- moment wurde für diese Arbeit entwickelt. Das Modell löst gewöhnliche Diffe- rentialgleichungen, welche sich aus der Kontinuitätsgleichung und der Poisson- Gleichung sowie Reaktionsgleichungen ergeben, zur Berechnung der (reduzierten) elektrischen Feldstärke, sowie Teilchendichten von e^− , N_2^+, O_2^+ , O^- , O^+ , N^+ , N_2 und O_2 . Mithilfe dieses Modells wird das notwendige Strommoment be- stimmt, welches für die Entstehung einer Entladung in der Mesosphäre, einem Sprite, notwendig ist. Dazu werden Ratenkoeffizienten von BOLSIG+, Borisov et al./Sentman et al. und Pasko et al. verwendet. Abhängig von den verwendeten Ratenkoeffizienten liegt die kritische reduzierte elektrische Feldstärke zwischen 93 Td und 138 Td, sowie das für einen Sprite notwendige Strommoment zwischen 200 kA km und 300 kA km. Ein Streamer kann bei denselben reduzierten elektri- schen Feldstärken entstehen.
