description: Cattle producers tend to market cattle about the same time each year. However, exogenous (external) factors can influence when cattle are marketed. An example of an extremely short-run factor is precipitation events such as rain or snow. Weather events can prohibit cattle producers from getting a truck and trailer to the cattle loading facilities, resulting in delayed marketing (sale). However, these events are generally short-lived and only change sales dates by a week or two. Alternatively, there are other events that can cause cattle producers to change or delay marketing cattle, because such events negatively influence cattle prices. Events that negatively influence cattle prices may be short-lived, or they can have influence on the market price for an extended period of time. When a short-term event becomes a long-term event with an unknown ending, the cattle producer cannot know for certain how long prices will be depressed. Thus, when cattle prices decline, cattle producers tend to delay marketing to give the market time to recover or regain some of its losses. This can be a useful strategy for a short period of time, but most cattle producers have finite resources, which means they cannot hold onto their cattle indefinitely. This strategy does not even consider that cattle are “perishable products,” in that they will continue to grow as time passes and will eventually have to move through the beef supply chain. Coronavirus is one of those events that has resulted in producers changing their cattle marketing plans in the state of Tennessee and across the country because it has had a negative effect on cattle prices. The purpose of this publication is to illustrate how cattle marketing receipts of feeder and stocker cattle have been influenced by coronavirus by providing information on the quantity of cattle that were delayed moving through the beef supply chain.

description: Additional file 2: Plate 1. The survey plot was installed in Albongbunji Basin, Ulleungdo, taken in 2019 (left). This young beech forest (approximately 60 years old) is in the stem exclusion stage of forest development. Broken stems of the canopy species Prunus takesimensis (Ulleungdo cherry, endemic species) and Acer pictum var. mono originated from gap events induced by stochastic disturbances (wind and mechanical damage), which were observed at an earlier stage than in traditional development models. The forest floor of the survey plot is continuously changing in terms of micro-level geomorphology due to soil deposition caused by heavy rains. In part of the survey plot, soil deposition has been taking place since 2016 (right). The red arrow on the picture is the spot where the number tag was attached at the breast height (120 cm) in 2009.

description: We calculate the additional force due to two-axion exchange acting in a sphere-disc geometry, used in experiments on measuring the gradient of the Casimir force. With this result, stronger constraints on the pseudoscalar coupling constants of an axion and axion-like particles to a proton and a neutron are obtained over the wide range of axion masses from 0.03mV to 1eV. Among the three experiments with Au-Au, Au-Ni and Ni-Ni boundary surfaces performed by means of dynamic atomic force microscope, major improving is achieved for the experiment with Au-Au test bodies. Here, the constraints obtained are stronger up to a factor of 170, as compared to the previously known ones. The largest strengthening holds for the axion mass 0.3eV.

Effect of planetary gearboxes on the dynamics of rotating systems
Creators: name: Tatar, Ali
Publisher: name: Imperial College London
Year: 2019

description: The coupled dynamic behaviour of planetary geared rotor systems is much less well understood compared to the classical geared rotor systems. For a better understanding, this research project investigates the coupled dynamic behaviour of planetary geared rotor systems and how the planetary gearbox parameters affect their global dynamics. In the numerical study, a six degrees of freedom hybrid dynamic model of a planetary geared rotor system is created in the recently developed “GEAROT” rotor dynamics software by considering gyroscopic effects. Based on the modal analysis results of the hybrid dynamic model, the vibration modes are classified as coupled torsional-axial, lateral and gearbox for the helical gear configuration, and torsional, axial, lateral and gearbox for the spur one. Modal energy analysis is used to quantify the coupling level between the shafts and planetary gearbox, which highlights the effect of a planetary gearbox on the dynamic behaviour of a rotating system. An extensive planetary gearbox parameter study including gear contact, gearbox mass and support, and planet gear parameters is conducted using the hybrid dynamic model to investigate the parameter effects on the modal behaviour of planetary geared rotors. The sensitivity of planetary geared rotor vibration modes to the gearbox parameters is determined by computing the frequency shifts and comparing the mode shapes between the two extreme cases. In the experimental study, free-free impact hammer tests are carried out on a planetary geared rotor assembly to validate the numerical modal analyses results in “GEAROT”. On the basis of both experimental and numerical modal analysis of planetary geared rotors, the lateral vibration modes are identified as “in phase” and “out of phase”. Briefly, the numerically identified lateral modal behaviour of planetary geared rotor systems is successfully validated with the experimental modal analysis results.

description: Infinite games where several players seek to coordinate under imperfect information are known to be intractable, unless the information flow is severely restricted. Examples of undecidable cases typically feature a situation where players become uncertain about the current state of the game, and this uncertainty lasts forever. Here we consider games where the players attain certainty about the current state over and over again along any play. For finite-state games, we note that this kind of recurring certainty implies a stronger condition of periodic certainty, that is, the events of state certainty ultimately occur at uniform, regular intervals. We show that it is decidable whether a given game presents recurring certainty, and that, if so, the problem of synthesising coordination strategies under w-regular winning conditions is solvable.

description: Excessive crosstie wear and abrasion and ballast wear and fouling are two of the fundamental problems contributing to inadequate railroad track performance. This adversely affects the attainment and long-term maintenance of desired track geometric requirements. The magnitudes and distribution of the stresses at the crosstie-ballast (CT-B) interface must be known to determine the stress distribution on the ballast. However, the stresses at the top of the ballast often vary significantly. This study examines a new approach to predicting dynamic contact pressures at the interface of crosstie and ballast using the ‘square wave theory.’ A data set of in-track CT-B interfacial pressures, taken from a freight mainline at Mascot, TN limited to speeds up to 64 km/h, in 2018, was analyzed to develop relationships in the form of equations to predict dynamic contact pressures as a function of specific information, including train speed, weight, number of axles, and wheel spacing. Several equations were developed to predict CT-B interfacial pressures as a function of these variables. Additionally, the developed square wave theory and obtained data are analyzed and compared to traditional recommended design practices. Longitudinal stress distribution over the crossties and the stress distribution along the crossties are presented. Based on the analyzed CT-B interfacial pressures, the ballast stress distribution is discussed, and recommendations are made.

Computational genomics of developmental gene regulation
Creators: name: Perry, Malcolm
Publisher: name: Imperial College London
Year: 2019

description: The development of multicellular organisms requires the precise execution of complex transcriptional programs. The demands posed by development, coupled with the relatively late evolution of multicellularity, could have led to a separate mode of gene regulation for gene involved in, and regulated throughout development. I investigated the regulation of genes by enhancers using histone modifications coupled to gene expression, based on the observa- tion that developmental genes are surrounded by dense clusters of conserved enhancers which act in concert. Genes regulated by enhancers are much more likely to be developmentally regulated genes, and many enhancers at each loci co-ordinate to direct transcription across multiple tissues. CAGE-seq is a powerful tool for determining the structure of promot- ers. I analysed promoters in Amphioxus using CAGE-seq to determine if the diverse promoter architectures observed in vertebrates had ancestral ori- gins. Promoters in amphioxus can be divided into developmental and house- keeping promoters, which each have characteristic patterns of dinucleotide enrichment. Housekeeping promoters in Amphioxus have a novel promoter architecture, and a contain a high frequency of bidirectional promoters, which represents the ancestral vertebrate state. This set of genes highlight the mal- leability of promoter architecture during evolution. I developed a package in R/Bioconductor ‘heatmaps’ to enable effective visualisation of this, and other, data. Taken together, these results suggest a second mode of regulation in ver- tebrates governing the regulation of developmental genes.

 Abstract Deucravacitinib (SOTYKTU™) is a tyrosine kinase 2 (TYK2) inhibitor that expands the availability of effective oral treatments for the management of moderate to severe plaque psoriasis in adults. In contrast to Janus kinase inhibitors that target Janus kinase 1–3, deucravacitinib selectively inhibits TYK2. This mechanism may allow more specific targeting of type-1 interferons and the interleukin (IL)-23/IL-17 pathway, which are associated with the pathophysiology of psoriasis. In two phase 3 clinical trials, deucravacitinib was superior to placebo in meeting coprimary efficacy endpoints at week 16. The efficacy of deucravacitinib was maintained in most patients who received treatment for 2 years. Deucravacitinib was generally well tolerated during the phase 3 trials and no new safety signals were reported after 2 years of treatment. Deucravacitinib was superior to apremilast with respect to almost all efficacy endpoints.

Spatial organisation of low-frequency unsteadiness in oblique shock wave -- boundary layer interactions
Creators: name: Rabey, Paige
Publisher: name: Imperial College London
Year: 2020

description: This thesis examines the spatial organisation of low-frequency unsteadiness of incident -- reflected shock -- boundary layer interactions (SBLIs). Such SBLI unsteadiness continues to be an active topic of research due to its detrimental effects on supersonic engine intakes, for example. Recent studies have investigated the influence of duct geometry on the topology of the shock-induced separation bubble. This thesis aims to unite these two topics in order to investigate the inter-dependence of the low-frequency unsteadiness and the three-dimensional separation bubble shape and to contribute to the understanding of the low-frequency dynamics. In this study, experiments have been undertaken on eight test cases in the Imperial College blow-down supersonic wind tunnel with a freestream Mach number of two. Three different interaction strengths were achieved by turning the flow $12\,\degree$, ${10\,\degree}$ and ${8\,\degree}$. Each strength interaction was examined at three different effective aspect ratios ${\AR=1}$, ${\AR=1.3}$ and ${\AR=2}$, with the exception of the $12\,\degree$ for which the latter was not examined. The separation regions were measured by oil flow visualisation and the unsteadiness was inferred from pressure fluctuation measurements under the separation shock across the full span of the wind tunnel floor. The obtained measurements provide the first experimentally-measured two-dimensional maps that capture the unsteady characteristics beneath an SBLI. The maps show that low-frequency motion exists across the entire span of the separation shock and is more prevalent where earlier separation occurs. Similar low-frequency unsteadiness is observed in the corner separations and it appears that the interaction, including the central and corner separation bubbles and the separation shock, moves as a whole entity. This might be driven by the pressure gradient across the incident shock rather than by the upstream boundary layer or separation bubble. The driving force of the incident shock strength appears to dictate the characteristic frequency and the product of the amplitude of shock motion and separation volume.

description: The VUV absorption cross sections of most molecular solids present in interstellar ice mantles with the exception of H2O, NH3, and CO2 have not been reported yet. Models of ice photoprocessing depend on the VUV absorption cross section of the ice to estimate the penetration depth and radiation dose, and in the past, gas phase cross section values were used as an approximation. We aim to estimate the VUV absorption cross section of molecular ice components. Pure ices composed of CO, H2O, CH3OH, NH3, or H2S were deposited at 8 K. The column density of the ice samples was measured in situ by infrared spectroscopy in transmittance. VUV spectra of the ice samples were collected in the 120-160 nm (10.33-7.74 eV) range using a commercial microwave-discharged hydrogen flow lamp. We provide VUV absorption cross sections of the reported molecular ices. Our results agree with those previously reported for H2O and NH3 ices. Vacuum-UV absorption cross section of CH3OH, CO, and H2S in solid phase are reported for the first time. H2S presents the highest absorption in the 120-160 nm range. Our method allows fast and readily available VUV spectroscopy of ices without the need to use a synchrotron beamline. We found that the ice absorption cross sections can be very different from the gas-phase values, and therefore, our data will significantly improve models that simulate the VUV photoprocessing and photodesorption of ice mantles. Photodesorption rates of pure ices, expressed in molecules per absorbed photon, can be derived from our data.

Function spaces on Lie groups and applications

Publisher: name: Imperial College London
Year: 2019

description: The overall goal of the thesis is to investigate hypoelliptic and subelliptic functional inequalities of different types and the corresponding function spaces on homogeneous nilpotent Lie groups, which include the cases of Rn, Heisenberg, stratified and more general graded Lie groups. In such settings we derive a variety of functional inequalities including Hardy, Rellich, Hardy-Littllewood-Sobolev, Gagliardo-Nirenberg, Caffarelli-Kohn-Nirenberg, uncertainty and other related inequalities, and their extensions. The approach for obtaining hypoelliptic functional inequalities relies on establishing integral versions of Hardy inequalities on homogeneous Lie groups, for which we also find necessary and sufficient conditions for the weights for such inequalities to be true. Consequently, we link such integral Hardy inequalities to different hypoelliptic inequalities by using the Riesz and Bessel kernels associated to the described hypoelliptic operators. Moreover, we describe Euler–Hilbert–Sobolev, Sobolev–Lorentz–Zygmund, Besov type, Morrey and generalised Morrey spaces on homogeneous Lie groups. We also study the boundedness of the Bessel–Riesz operators, generalised Bessel–Riesz operators, generalised fractional integral operators and Olsen type inequalities. The obtained results on homogeneous Lie groups in this thesis give new statements in the Euclidean setting of Rn when we are working with anisotropic differential structures. Furthermore, even in the isotropic situation in Rn, one novelty of all the obtained results is in the arbitrariness of the choice of any homogeneous quasi-norm, and some estimates are also new in the usual isotropic structure of Rn with the Euclidean norm.
A co-design approach to exploring physical activity, stress, and wellbeing in two British police forces

Subjects: Sport and exercise psychology

description: The aim of this research was to explore stress and wellbeing in two British police forces, to discover what factors were important for police wellbeing and how the wellbeing of police force workers might be better supported. A collaborative (co-design) approach and the Double Diamond (Design Council, 2019) framework were used to guide the research. The sample population for this research was recruited from two UK police organizations. Informed by the Demands Resources and Individual Effects model of work-related stress (Mark & Smith, 2008), Study 1 was a quantitative assessment of the factors associated with stress and wellbeing in the police forces. Work resources (perception of reward, control, support) and individual characteristics (medium and high physical activity behavior) were found to significantly moderate the relationships between work demands and perceived job stress to benefit psychological wellbeing outcomes. To gain deeper insight into physical activity as a potential driver for wellbeing, a series of qualitative enquiries were conducted in Study 2a and 2b. Focus groups were used to explore the relationship between physical activity and wellbeing in Study 2a, and individual interviews were conducted with inactive (low physical activity behavior) police force workers to establish the barriers and enablers to their physical activity behavior in Study 2b. Analysis indicated that psychological capability, social opportunity and motivation were influential in police physical activity behavior. Building on the qualitative insights, Study 3 focused on the development of a context-specific physical activity intervention, co-designed with one department within the police force. Using the Behavior Change Wheel (Michie et al., 2011), the outcome of this collaborative approach was a protocol for an ‘Exertime’ intervention. ‘Exertime’ was an e-health software program which prompted police staff to engage in short-bursts of physical activity throughout their shifts and was supported by supervisors encouraging their staffs’ participation. Holistically, the program of research has advanced knowledge on work-related stress, wellbeing, and physical activity, with practical implications for police force organizations. These include providing support for physical activity at work as a mechanism to maintain wellbeing and providing specific training for supervisors to manage favorable relationships with their staff. A series of learning points can be taken from the research to support future PhD researchers, their supervisors and the external organizations they work with in conducting ecologically valid research.

The BioExcel methodology for developing dynamic, scalable, reliable and portable computational biomolecular workflows
Creators: name: Ejarque, Jorge
Publisher: name: Zenodo
Year: 2022

description: Developing complex biomolecular workflows is not always straightforward. It requires tedious developments to enable the interoperability between the different biomolecular simulation and analysis tools. Moreover, the need to execute the pipelines on distributed systems increases the complexity of these developments. To address these issues, we propose a methodology to simplify the implementation of these workflows on HPC infrastructures. It combines a library, the BioExcel Building Blocks (BioBBs), that allows scientists to implement biomolecular pipelines as Python scripts, and the PyCOMPSs programming framework which allows to easily convert Python scripts into task-based parallel workflows executed in distributed computing systems such as HPC clusters, clouds, containerized platforms, etc. Using this methodology, we have implemented a set of computational molecular workflows and we have performed several experiments to validate its portability, scalability, reliability and malleability.

Both nanowires without defects and with internal tunneling barriers were studied. The measurements were performed at various carrier concentrations in the systems and opacity of contact-to-wire interfaces. The regime of Coulomb blockade is investigated in detail including negative differential conductivity of the whole system. The situation with open contacts with one tunneling barrier and undivided wire is also addressed. Special attention is devoted to recently observed quasi-periodic standing waves.

description: A alimentação é uma necessidade básica de todos os seres humanos, porém a relação dos consumidores com a segurança dos alimentos pode ficar comprometida, devido à sua falta de literacia alimentar. Embora o cumprimento da segurança alimentar seja uma responsabilidade de todos, nem sempre os consumidores têm isso em consideração. Desta forma, o presente estudo analisou o comportamento do consumidor português no que concerne à segurança alimentar, comparando dois momentos temporais. A investigação foi descritiva, com o levantamento de dados quantitativos através de um questionário partilhado na internet num período de 5 meses (junho-outubro de 2019), replicando o estudo de Toscano em 2006 e comparando-os. Os resultados permitiram conhecer a evolução da ligação do consumidor português com a segurança alimentar assim como compreender a importância que a mesma assume no seu dia-a-dia, mediante da análise do seu nível de conhecimento e preocupação e da avaliação da influência dos rótulos alimentares, permitindo evidenciar as principais alterações que ocorreram desde a situação existente em 2006.

description: Efficiently controlling the diffusion process is crucial in the study of diffusion problem in complex systems. In the sense of random walks with a single trap, mean trapping time(MTT) and mean diffusing time(MDT) are good measures of trapping efficiency and diffusion efficiency respectively. They both vary with the location of the node. In this paper, we study random walks on T-fractal and provided general methods to calculate the MTT for any target node and the MDT for any source node. Using the MTT and the MDT as the measure of trapping efficiency and diffusion efficiency respectively, we compare the trapping efficiency and diffusion efficiency among all nodes of T-fractal and find the best (or worst) trapping sites and the best (or worst) diffusing sites. Our results show that: the hub node of T-fractal is the best trapping site, but it is also the worst diffusing site, the three boundary nodes are the worst trapping sites, but they are also the best diffusing sites. Comparing the minimum and maximum of MTT and MDT, we found that the maximum of MTT is almost $6$ times of the minimum for MTT and the maximum of MDT is almost equal to the minimum for MDT. These results show that the location of target node has big effect on the trapping efficiency, but the location of source node almost has no effect on diffusion efficiency. We also conducted numerical simulation to test the results we have derived, the results we derived are consistent with those obtained by numerical simulation.

description: Medical decisions such as benefit-risk assessments of treatments should be based on the best clinical evidence but also require subjective value judgements regarding the impact of disease and treatment outcomes. This thesis argues for a Bayesian implementation of Multi-Criteria Decision Analysis (MCDA) for such problems. It seeks to establish whether suitable Bayesian models can be constructed given the variety of data formats and the interdependencies between the many variables involved. A modelling framework is developed for joint multivariate Bayesian inference of treatment effects and preference values based on data from clinical trials and stated preference studies. This method allows the sampling uncertainty of the parameters to be reflected in the analysis, overcoming a recognised shortcoming of MCDA. Markov Chain Monte Carlo simulation is used to derive the posterior distributions. The models are illustrated using a case study involving treatments for relapsing remitting multiple sclerosis. The clinical evidence synthesis has several advantages over existing multivariate evidence synthesis models, including a comprehensive flexible allowance for correlations, compatibility with any number of treatments and outcomes, and the ability to estimate unreported treatment-outcome combinations. The preference models can analyse data from a variety of elicitation methods such as discrete choice, Analytic Hierarchy Process and swing weighting. In the case of swing weighting no Bayesian analysis has previously been presented, and the results suggest a possible flaw in the standard deterministic analysis that may bias the preference estimates when judgements are subject to random variability. A novel meta-analysis model for preference elicitation studies is also presented. The framework has the unique ability to analyse data from multiple methods jointly to yield a common set of preference parameters. These results demonstrate the flexibility of the Bayesian approach, and the depth of insight it can provide into the impact of uncertainty and heterogeneity in multi-criteria medical decisions.

description: Timor-Leste é um país com um rico património natural e cultural, com grande potencial para desenvolver o turismo para suportar o desenvolvimento económico do país. As infraestruturas turísticas são modestas e os atributos turísticos deficientes, pelo que o número de visitantes é relativamente pequeno. A questão que se coloca é “Como ultrapassar estas limitações ao desenvolvimento do setor do turismo. Este estudo procurou identificar as motivações e expetativas dos visitantes assim como a sua satisfação com o destino Timor-Leste. Para a sua concretização, foram recolhidos dados primários através de inquérito por questionários junto de visitantes de Timor-Leste. O trabalho concluiu que a maioria dos entrevistados, visitantes, era proveniente d Austrália, logo seguida de Portuga e que a finalidade da viagem era maioritariamente profissional. Os atributos constituídos pelo clima, tranquilidade e hospitalidade foram valorizados de forma satisfatória ou muito satisfatória pelos visitantes; nos do grupo respeitante ao usufruto direto, a satisfação e a muita satisfação foram sempre superiores à insatisfação embora com alguns sinais de alerta na insatisfação;, nos preços praticados, o grau de insatisfação rondou os 40%, e na qualidade das infraestruturas verificaram-se os maiores sinais de insatisfação por parte dos visitantes. As propostas de melhoria e recomendações foram: não deixar lixo nas praias, melhoria do saneamento, condições das estradas, informações e guias turísticos, condições de alojamento e de ecoturismo, transportes públicos em Díli e nos Distritos, animação, atração turística e gastronomia tradicional.

description: O contexto competitivo das organizações agrícolas, nomeadamente, as associações e as cooperativas, está a ser influenciado pelo paradigma do desenvolvimento sustentável, sendo necessário ter em conta os requisitos da sustentabilidade na sua atividade. Essas organizações agrícolas poderão facilitar a interação entre os agricultores e, por conseguinte, favorecer a produção e a comercialização dos seus produtos agrícolas de forma sustentável, bem como o acesso a serviços que promovam a adoção de práticas sustentáveis. Elas transmitem a informação aos seus associados, possibilitado o desenvolvimento tecnológico e são atores chave na melhoria da produtividade e nas questões ambientais. Neste sentido, com o objetivo de definir e identificar indicadores de avaliação da sustentabilidade das organizações agrícolas, este estudo desenvolve uma análise sistemática da literatura focada em artigos científicos das bases bibliográficas da Web of Science e Scopus. Os resultados mostraram que os indicadores de sustentabilidade permitem subsidiar modelos preditivos de avaliação da sustentabilidade e destacam sua contribuição para a melhoria da gestão das organizações agropecuárias, permitindo a visualização de pontos fortes e oportunidades para enfrentar fraquezas e ameaças. Por meio do mapeamento de documentos, foi possível identificar indicadores de âmbito económico, ambiental e social, que constituem um ponto de partida para uma agenda de investigação focada no papel das organizações agrícolas na sustentabilidade do setor agrícola.

description: [Abridged] We develop and benchmark a fast and easy-to-use effective-opacity formalism for line and continuum radiative transfer in an accelerating two-component clumpy medium. The formalism bridges the limits of optically thin and thick clumps, and is here used to i) design a simple vorosity-modified Sobolev with exact integration (vmSEI) method for analyzing UV wind resonance lines in hot, massive stars, and ii) derive simple correction factors to the line force driving the outflows of such stars. We show that (for a given ionization factor) UV resonance doublets may be used to analytically predict the upward corrections in empirically inferred mass-loss rates associated with porosity in velocity space (a.k.a. velocity-porosity, or vorosity), but that severe solution degeneracies exist. For an inter-clump density set to 1 % of the mean density, we for O and B supergiants derive upward empirical mass-loss corrections of typically factors of either ~5 or ~50, depending on which of the two applicable solutions is chosen. Overall, our results indicate this solution dichotomy severely limits the use of UV resonance lines as direct mass-loss indicators of clumped hot stellar winds. We next apply the effective-opacity formalism to the standard CAK theory of line-driven winds. By analytic and numerical hydrodynamics calculations, we show that in cases where vorosity is important at the critical point setting the mass-loss rate, the reduced line-force leads to a lower theoretical mass loss, by a factor scaling with the normalized velocity filling factor fvel. On the other hand, if vorosity is important only above this critical point, the predicted mass loss is not affected, but the wind terminal speed is reduced. This shows that porosity in velocity space can have a significant impact not only on the diagnostics, but also on the dynamics and theory of radiatively driven winds.

description: Atom chips made of superconducting material can generate magnetic traps with significantly reduced noise. Recently, several designs for superconducting chips have been theoretically analyzed and experimentally tested, for cases with many vortices considered as an average vortex density. Here we show theoretically, for the first time, how the magnetic field of a $\it single$ vortex, pinned by a superconducting nano-disc of radius $\sim$100 nm and combined with an external bias field parallel to the disc surface, yields a closed 3D trap for cold atoms. The size of the trap, and its height above the superconductor surface, are typically tens or hundreds of nanometers. We estimate the average lifetime $τ$ of $^{87}$Rb (rubidium) atoms (subject to thermal escape and Majorana spin flips) in the range 0.05-1.0 ms. Next, we model the trap in a quantum adiabatic approximation and apply Fermi's rule to estimate the lifetime of $^{87}$Rb atoms in the ground state of this trap. We obtain similar lifetimes $τ$ as in the semiclassical estimate, in the range 0.05-3.5 ms. We find that $τ$ depends on the gradient $B_0$ of the vortex's magnetic field according to $τ\sim(B_0)^{-2/3}$.

title: Regionale Versorgungsunterschiede bei der Durchführung ambulanter oder stationärer Schwangerschaftsabbrüche in Krankenhäusern in Deutschland

description: Hintergrund:
Im Jahr 2019 wurden durchschnittlich 20,9 % der Schwangerschaftsabbrüche in Deutschland in Krankenhäusern durchgeführt. Die Versorgung von Schwangerschaftsabbrüchen im Krankenhaussektor ist trotz dieses Anteils bisher nicht genügend wissenschaftlich untersucht. Es wird angenommen, dass in Deutschland wesentliche Versorgungsunterschiede bei ambulant oder stationär in Krankenhäusern durchgeführten Schwangerschaftsabbrüchen bestehen.

Methodik:
Um regionale Unterschiede bei der Versorgung eines freiwilligen Schwangerschaftsabbruchs in Krankenhäusern zu identifizieren, wurde eine Sonderauswertung von Schwangerschaftsstatistiken vom Jahre 2019 analysiert. Die Sonderauswertung wurde für das Projekt „Medizinische Versorgungssituation zur Durchführung eines Schwangerschaftsabbruchs im Krankenhaussektor in Deutschland (MedVersKH)“ vom Statistischen Bundesamt in Begleitung der Universität Kassel geleistet. Mit der vorliegenden Studie werden diese Statistiken zum Schwangerschaftsabbruch zum ersten Mal tiefergehend ausgewertet und dargestellt.

Ergebnisse:
Markante regionale Unterschiede zwischen den Bundesländern wurden bei Schwangerschaftsabbrüchen, die im Krankenhaussektor nach der Beratungsregelung vorgenommen wurden, identifiziert. Während z. B. 2019 die Bundesquote für freiwillige Schwangerschaftsabbrüche im gebärfähigen Alter (15 bis unter 50 Jahre), die in Ambulanzen von Krankenhäusern durchgeführt wurden, bei 10,4 Abbrüchen je 10.000 Frauen liegt, variieren die Quoten nach Bundesland von 1,9 in Bayern bis 51,8 Abbrüchen in Brandenburg. Dabei liegen die höchsten Schwangerschaftsabbruchquoten überwiegend in den ostdeutschen Bundesländern Brandenburg, Mecklenburg-Vorpommern, Sachsen-Anhalt, Thüringen und Sachsen.

Schlussfolgerungen:
Die Auswertung der Schwangerschaftsabbrüche in Krankenhäusern belegt große regionale Auffälligkeiten beim Vergleich der Bundesländer. Im Gesundheitssystem sind Fragen nach dem Leistungsgeschehen in heterogenen Versorgungsstrukturen sowie der Zugänglichkeit und regionalen Bedarfsgerechtigkeit noch weitgehend offen. Es mangelt an entsprechenden Gesundheitssystemanalysen und Daten für die Versorgungsforschung.
