description: Nur ein Teil der Menschen mit COVID-19 ist von einem schweren oder kritischen Krankheitsverlauf betroffen. Viele dieser Personen weisen Risiken wie ein hohes Alter oder Vorerkrankungen auf und stehen bei Schutzmaßnahmen besonders im Fokus. Ziel ist es, die Zahl dieser Personen in Deutschland zu bestimmen und nach Alter, Geschlecht, Bildung, Lebensform und Bundesland zu differenzieren. Die Auswertungen beruhen auf der Studie Gesundheit in Deutschland aktuell (GEDA) 2019/2020-EHIS, die als bundesweite telefonische Querschnittbefragung zwischen April 2019 und Oktober 2020 durchgeführt wurde. Die Definition eines erhöhten Risikos für einen schweren COVID-19-Verlauf erfolgte vornehmlich durch das Alter und die Vorerkrankungen der Befragten. Etwa 36,5 Millionen Menschen in Deutschland haben danach ein erhöhtes Risiko für einen schweren COVID-19-Verlauf. Unter diesen gehören 21,6 Millionen Menschen zur Hochrisikogruppe. Überdurchschnittlich viele Personen unter Risiko sind alleinlebend. Die Prävalenz für ein erhöhtes Risiko ist bei Männern mittlerer Altersgruppen höher als unter gleichaltrigen Frauen und bei Personen mit geringer Bildung deutlich höher als unter Hochgebildeten. Im Saarland und in den ostdeutschen Bundesländern leben anteilig die meisten Menschen mit einem erhöhten Risiko. Bei der Bekämpfung der Pandemie ist zu berücksichtigen, dass mehr als die Hälfte der Bevölkerung ab 15 Jahren ein erhöhtes Risiko aufweist. Zudem kann die regional unterschiedliche Risikolast bei der Maßnahmenplanung relevant sein.

description: The spectral, timing, and jet formation properties of neutron stars in low mass x-ray binary systems are influenced by the presence of central magnetic moments. Similar features shown by the galactic black hole candidates (GBHC) strongly suggest that their compact cores might be intrinsically magnetic as well. We show that the existence of intrinsically magnetic GBHC is consistent with a new class of solutions of the Einstein field equations of General Relativity. These solutions are based on a strict adherence to the Strong Principle of Equivalence (SPOE) requirement that the world lines of physical matter must remain timelike in all regions of spacetime. The new solutions emerge when the structure and radiation transfer properties of the energy momentum tensor on the right hand side of the Einstein field equations are appropriately chosen to dynamically enforce this SPOE requirement of timelike world line completeness. In this context, we find that the Einstein field equations allow the existence of highly red shifted, Magnetospheric, Eternally Collapsing Objects (MECO). MECO necessarily possess intrinsic magnetic moments and they do not have trapped surfaces that lead to event horizons and curvature singularities. Their most striking features are equipartition magnetic fields, pair plasma atmospheres and extreme gravitational redshifts. Since MECO lifetimes are orders of magnitude greater than a Hubble time, they provide an elegant and unified framework for understanding a broad range of observations of GBHC and active galactic nuclei. We examine their spectral, timing and jet formation properties and discuss characteristics that might lead to their confirmation.

description: Anisotropic multi-slice Cardiac Magnetic Resonance (CMR) Images are conventionally acquired in patient-specific short-axis (SAX) orientation. In specific cardiovascular diseases that affect right ventricular (RV) morphology, acquisitions in standard axial (AX) orientation are preferred by some investigators, due to potential superiority in RV volume measurement for treatment planning. Unfortunately, due to the rare occurrence of these diseases, data in this domain is scarce. Recent research in deep learning-based methods mainly focused on SAX CMR images and they had proven to be very successful. In this work, we show that there is a considerable domain shift between AX and SAX images, and therefore, direct application of existing models yield sub-optimal results on AX samples. We propose a novel unsupervised domain adaptation approach, which uses task-related probabilities in an attention mechanism. Beyond that, cycle consistency is imposed on the learned patient-individual 3D rigid transformation to improve stability when automatically re-sampling the AX images to SAX orientations. The network was trained on 122 registered 3D AX-SAX CMR volume pairs from a multi-centric patient cohort. A mean 3D Dice of $0.86\pm{0.06}$ for the left ventricle, $0.65\pm{0.08}$ for the myocardium, and $0.77\pm{0.10}$ for the right ventricle could be achieved. This is an improvement of $25\%$ in Dice for RV in comparison to direct application on axial slices. To conclude, our pre-trained task module has neither seen CMR images nor labels from the target domain, but is able to segment them after the domain gap is reduced.

description: The Soviet occupation authorities in East Germany sent their American counterparts in West Germany into a frenzy in 1948 with their release of Mikhail Romm's Russkii Vopros; the film was an unequivocally biting indictment of American capitalism, which featured an opening montage of newsreel footage showing American poverty, decadence, and--most provocatively--racial inequality. The American administration's lightning-fast response was Ernst Lubitsch's Ninotchka, a 1939 film in which Greta Garbo plays a communist official comically seduced by the pleasures of capitalism. This episode in Cold War history became the focal point of my master's thesis for the clarity with which it revealed both the power of film as a tool for relaying ideology and political rhetoric (a fact that had long been clear to both American and Soviet politicians and propagandists), as well as the potential of cinema to reveal the fears, hang-ups and values of the societies which produced, consumed, and contested it.
Thermodynamic model and data on the partitioning of nonprocess elements between kraft fibres and water in a pulp suspension
Creators: name: Bygrave, Geoffrey Scott
Publisher: name: University of British Columbia
Year: 2009

description: The partitioning of non-process elements in kraft fibre suspensions has been modeled using the Donnan equilibrium framework with activity coefficients introduced to account for the non-ideal nature of the electrolyte solutions. Activity coefficients have been obtained using Pitzer's model. Total anionic charge, dissociation constants, and mass of water within the fibres are used as input to the model and were determined by independent experiments. Partitioning data were also obtained for a post brown stock washer kraft pulp, from an interior BC mill, for the metal ions of Na⁺, Ca⁺² , and Mg⁺² over the pH range 2-13. Such data above a pH of 11 were not previously available in the literature. Two models were used to obtain the charge on the fibres at any pH; a two dissociation constant model (corresponding roughly to the carboxyl and phenolic hydroxyl) and an "exact" charge model. Results indicate that below a pH of 7 both models do a good job of representing the experimental data obtained in this work and data available in the literature. Above a pH of 7 the two dissociation constant model under-predicts the partitioning data while the exact charge model follows the experimental data over the entire pH range. This indicates Donnan equilibrium is an excellent framework for non-process element partitioning prediction as long as the fibre charge is known accurately. Experiments with elevated Mg and Ca contents were also performed, resulting in precipitation within the fibres at pHs above 10. The model does not account for precipitation phenomena that may occur when concentrations of Ca and Mg are increased above those naturally occurring in post brown stock pulps.

description: We analyze the decay of classically chaotic quantum systems in the presence of fast ballistic escape routes on the Ehrenfest time scale. For a continuous excitation process, the form factor of the decay cross section deviates from the universal random-matrix result on the Heisenberg time scale, i.e. for times much larger than the time for ballistic escape. We derive an exact analytical description and compare our results with numerical simulations for a dynamical model.

description: Managing and monitoring AI models in production, also known as machine learning operations (MLOps), has become essential in our days, resulting in the need for highly reliable MLOps platforms and frameworks. In the AI4EOSC project in order to provide our customers with the best available ones, we reviewed the field of open-source MLOps and examined the platforms that serve as the backbone of machine learning systems. Recognizing how tracking experiments may improve the process of organising and analysing the results of machine learning experiments as well as team collaboration and knowledge sharing should be noted. From workflow orchestration to drift detection, every aspect of the machine learning lifecycle was reviewed.
Based on that study and in order to aid scientists in their goal to achieve high model standards and implement MLOps practices, we deployed the MLflow platform for the AI4EOSC and iMagine users, are offering a Frouros drift detection python library, are developing a monitoring system for logging drift detection runs. The provided MLflow platform features a central remote tracking server so that every AI experimentation run either on the AI4EOSC platform or any other resources can be individually tracked and shared with other registered users if desired. Frouros library combines classical and more recent algorithms for both concept and data drift detection.
In this contribution, the global MLOps landscape of the continuously growing AI world will be presented together with our practical implementation in the AI4EOSC project and lessons learned from our users.

description: Less common ligand coordination of transition-metal centers is often associated with peculiar valence-shell electron configurations and outstanding physical properties. One example is the Fe$^+$ ion with linear coordination, actively investigated in the research area of single-molecule magnetism. Here we address the nature of 3$d^9$ states for Cu$^{2+}$ ions sitting in the center of trigonal bipyramidal ligand cages in the quasi-two-dimensional honeycomb compound InCu$_{2/3}$V$_{1/3}$O$_3$, whose unusual magnetic properties were intensively studied in the recent past. In particular, we discuss the interplay of structural effects, electron correlations, and spin-orbit couplings in this material. A relevant computational finding is a different sequence of the Cu ($xz$, $yz$) and ($xy$, $x^2\!-\!y^2$) levels as compared to existing electronic-structure models, which has implications for the interpretation of various excitation spectra. Spin-orbit interactions, both first- and second-order, turn out to be stronger than previously assumed, suggesting that rather rich single-ion magnetic properties can be in principle achieved also for the 3$d^9$ configuration by properly adjusting the sequence of crystal-field states for such less usual ligand coordination.

description: The long and complex Trypanosoma brucei development in the tsetse fly vector culminates when parasites gain mammalian infectivity in the salivary glands. A key step in this process is the establishment of monoallelic variant surface glycoprotein (VSG) expression and the formation of the VSG coat. The establishment of VSG monoallelic expression is complex and poorly understood, due to the multiple parasite stages present in the salivary glands. Therefore, we sought to further our understanding of this phenomenon by performing single-cell RNA-sequencing (scRNA-seq) on these trypanosome populations. We were able to capture the developmental program of trypanosomes in the salivary glands, identifying populations of epimastigote, gamete, pre-metacyclic and metacyclic cells. Our results show that parasite metabolism is dramatically remodeled during development in the salivary glands, with a shift in transcript abundance from tricarboxylic acid metabolism to glycolytic metabolism. Analysis of VSG gene expression in pre-metacyclic and metacyclic cells revealed a dynamic VSG gene activation program. Strikingly, we found that pre-metacyclic cells contain transcripts from multiple VSG genes, which resolves to singular VSG gene expression in mature metacyclic cells. Single molecule RNA fluorescence in situ hybridisation (smRNA-FISH) of VSGgene expression following in vitro metacyclogenesis confirmed this finding. Our data demonstrate that multiple VSGgenes are transcribed before a single gene is chosen. We propose a transcriptional race model governs the initiation of monoallelic expression.

description: We study in theory the generation and detection of electron spin coherence in nonlinear optical spectroscopy of semiconductor quantum dots doped with single electrons. In third-order differential transmission spectra, the inverse width of the ultra-narrow peak at degenerate pump and probe frequencies gives the spin relaxation time ($T_1$), and that of the Stoke and anti-Stoke spin resonances gives the effective spin dephasing time due to the inhomogeneous broadening ($T_2^*$). The spin dephasing time excluding the inhomogeneous broadening effect ($T_2$) is measured by the inverse width of ultra-narrow hole-burning resonances in fifth-order differential transmission spectra.

Decoherence is described by Kraus operators, which take into account dephasing and energy relaxation at an arbitrary temperature. We show that in the experiments with superconducting phase qubits the survival time for entanglement should be much longer than for the Bell inequality violation.

description: The New Deal's Civilian Conservation Corps (CCC) is often heralded as a perfect cohesion for solving two of the nation's most neglected resources: unemployed young men and a decimated natural landscape.  While this study does not debate this conclusion, it adds to this interpretation by focusing on a specific region, Garrett and Allegany Counties in Maryland, to explore the impact of the Corps at a local level. The examination includes the exploration of the history of the region, the changes to the landscape and surrounding environment, the effect of an influx of young men upon the nearby farming and mountain communities, and the economic impact for both the enrollees and for the local population.  A variety of sources were employed, including local archives and museums, photographs, official government publications, health statistics, crime statistics, marriage records, census records, newspaper articles, and artifacts in private collections.  The research process demonstrates the lack of material available to the public.  To that end, this project also involved processing documents for the Maryland State Archives and resulted in an exhibition proposal that incorporates all of the research with personal holdings, memoirs, and photographs.  Such an exhibit serves to reinsert the Civilian Conservation Corps into the local public memory, providing a tangible connection to the forests and parks that enhance the local community.

description: Citrus Huanglongbing leads to abnormal starch accumulation in citrus leaves, and its molecular mechanisms are not yet clear. In order to elucidate the role of starch metabolism in the interaction between citrus and Candidatus Liberibacter spp., this study used bioinformatics methods to identify genes related to starch synthesis in Citrus sinensis, analyze the chromosomal distribution, exon/intron structure, and phylogenetic relationship with orthologous genes in Arabidopsis thaliana, identify conserved motifs and structural domains of proteins encoded by genes related to starch synthesis in C. sinensis, cis-acting elements in promoter regions, and explore the expression pattern changes and transcriptional regulatory network of genes related to starch synthesis in C. sinensis during infection by Candidatus Liberibacter asiaticus and Xanthomonas citri subsp. citri. The study found that there are 17 starch synthesis-related genes in C. sinensis, unevenly distributed on 8 chromosomes. The number of exons in genes related to starch synthesis is significantly higher than the average number of exons in all genes of C. sinensis. Genes related to starch synthesis in C. sinensis and A. thaliana cluster into 4 groups. proteins encoded by starch synthesis-related genes have conserved motifs or structural domains consistent with their biological functions. the promoter regions of genes related to starch synthesis in C. sinensis contain various cis-acting elements involved in biotic and abiotic stresses. The expression patterns of genes related to starch synthesis in C. sinensis change significantly during the infection process by Candidatus Liberibacter asiaticus and X. citri subsp. citri., and transcriptional regulatory analysis suggests that multiple transcription factors are involved in regulating the expression of genes related to starch synthesis in C. sinensis. This study provides data support for in-depth analysis of starch synthesis metabolism in response to pathogen infection in C. sinensis, and offers new insights into the relationship between plant energy metabolism and immunity.

description: Chemical imaging synergistically combines the chemical differentiation and identification; capabilities of spectroscopy with the spatial location and morphological information provided through imaging. Chemical imaging is a universally applicable means for characterizing complex; biological systems and samples using techniques ranging from basic microscopic imaging to the more advanced high-resolution techniques like near-field scanning optical microscopy (NSOM). Despite the current means by which chemical imaging is achieved, the development of a tool for chemical imaging on the nanoscale in a dynamic label-free manner has remained challenging. Such a visualization tool could potentially provide new insight and understanding into such extracellular events like lipid rafting. This work has resulted in the development, characterization, and optimization of surfaceenhanced; Raman scattering (SERS)-based imaging probes for the detection and imaging of biochemical species in real-time on the nanoscale. The nanoimaging probes synergistically combine the imaging capabilities of a tapered fiber optic bundle with chemical identification and; quantification using SERS-based spectroscopy. To fabricate the SERS nanoimaging probes, fiber optic bundles are first tapered, resulting in equi-diameter nanometer scale fiber elements. Following tapering, the fiber bundles are suspended in a solution of hydrofluoric acid (HF acid), which etches fiber element cores at a more rapid rate than surrounding cladding to create a uniformly roughened surface of cladding peaks across the fiber bundle. Raman signal enhancement across the probe surface is achieved by selectively depositing an array of metal islands onto the cladding peaks via vacuum evaporation. These SERS nanoimaging probes can; therefore be used to image biochemical species in a non-destructive, label-free manner in

description: We consider the astrophysical and cosmological implications of the existence of a minimum density and mass due to the presence of the cosmological constant. If there is a minimum length in nature, then there is an absolute minimum mass corresponding to a hypothetical particle with radius of the order of the Planck length. On the other hand, quantum mechanical considerations suggest a different minimum mass. These particles associated with the dark energy can be interpreted as the ``quanta'' of the cosmological constant. We study the possibility that these particles can form stable stellar-type configurations through gravitational condensation, and their Jeans and Chandrasekhar masses are estimated. From the requirement of the energetic stability of the minimum density configuration on a macroscopic scale one obtains a mass of the order of 10^55 g, of the same order of magnitude as the mass of the universe. This mass can also be interpreted as the Jeans mass of the dark energy fluid. Furthermore we present a representation of the cosmological constant and of the total mass of the universe in terms of `classical' fundamental constants.

These corrections are completely encoded by a single function characterizing a generic four-dimensional quaternion-Kahler metric without isometries. We give explicit solutions for this function describing all one-instanton corrections, including the fluctuations around the instanton to all orders in the string coupling constant. In the semi-classical limit these results are in perfect agreement with previous supergravity calculations.

description: This thesis discusses the interacting relationship between China's nuclear arms control and nonproliferation policy and U.S.-China relations from 1979 to 2007. By exploring the interactions of the two countries in the context of the international nonproliferation regime, and using developments in North Korea, Iran and Taiwan as case studies, this thesis concludes that China's nuclear arms control and nonproliferation policy had shifted since the late 1970s to one characterized by active engagement, and it has continued to evolve. This evolution was related to the development of US-China relations. Constructive developments in U.S.-China relations may positively influence China's nuclear arms control and nonproliferation policy and China's active participation in nonproliferation may also prove beneficial in the development of U.S.-China relations.

We propose here general closure of the Ornstein Zernike equation, that is the sum of an arbitrary number of yukawas, and that that will go well beyond the MSA . For this closure we get for the Laplace transform of the pair correlation function . This function is easily transformed into S(k) by replacing the Laplace variable by the Fourier wariable. Although the method is general and valid for polydisperse systems, an explicit continued fraction solution is found for the monodisperse case.

description: This thesis presents a new computer-aided linkage design and simulation system for task driven path generation problem. Mechanism design is considered a mixture of science and art. The former is about utilizing computers to rigorously sizing a mechanism in meeting a set of design requirements. And the latter is about taking advantage of designers' experience to narrow down design domain and speed up the design process. The ultimate goal of the presented design system is to incorporate both science and art into the linkage design process by (1) developing an automatic design framework based on library searching and optimization techniques and (2) developing an interactive design framework based on advanced human-computer interfaces. To enable the design automation framework, we first built a library of open and closed planar curves generated by commonly used planar linkages. We then turned the classical linkage path generation problem into a library searching problem together with a local optimization problem. To enable the interactive design framework, we developed a set of design interfaces that facilitate designers intervene and steer the design process. This hybrid design system was developed based on our existing VRMDS (Virtual Reality Mechanism Design Studio) framework. The result is a versatile mechanism design tool that is beneficial to the early stages of the mechanism design process.

description: Data Management and Data Analytics are of huge importance to Business Process Outsourcing Providers in Customer Relationship Management (CRM) in order to offer tailor-made CRM Solutions to their business clients during presales, sales and aftersales. These solutions support business clients to improve their internal processes, as well as their customer service in a variety of communication channels (including e-mail, chat, social media, private messages, etc.) to reach out to end customers in an efficient way. As customer interactions may happen via various channels basically at any time, a crucial challenge is to efficiently store and integrate the data of the various channels in order to obtain a unified customer profile. This paper abstracts from the underlying platforms and instead considers the requirements to CRM solutions for the various communication channels, in order to devise a uniform and corporate-wide data architecture for an omni-channel customer view to maximize the business clients' value in customer retention and customer centric analytics. Especially, online customer segmentation integrating channel usage and preferences is presented as a very promising means for constructing a self-energising information loop which will lead to highly improved customer service along the whole customer journey.

description: Low-frequency radio observations are revealing an increasing number of diffuse synchrotron sources from galaxy clusters, dominantly in the form of radio halos or radio relics. The existence of this diffuse synchrotron emission indicates the presence of relativistic particles and magnetic fields. It is still an open question what mechanisms exactly are responsible for the population of relativistic electrons driving this synchrotron emission. The LOFAR Two-metre Sky Survey Deep Fields offer a unique view of this problem. Reaching noise levels below 30 $μ$Jy/beam, these are the deepest images made at the low frequency of 144 MHz. This paper presents a search for diffuse emission in galaxy clusters in the first data release of the LOFAR Deep Fields. We detect a new high-redshift radio halo with a flux density of $8.9 \pm 1.0$ mJy and corresponding luminosity of $P_{144\mathrm{MHz}}=(3.6 \pm 0.6)\times10^{25}$ W Hz$^{-1}$ in an X-ray detected cluster at $z=0.77$ with a mass estimate of $M_{500} = 3.3_{-1.7}^{+1.1} \times 10^{14} M_\odot.$ Deep upper limits are placed on clusters with non-detections. We compare the results to the correlation between halo luminosity and cluster mass derived for radio halos found in the literature. This study is one of few to find diffuse emission in low mass ($M_{500} < 5\times10^{14} M_\odot$) systems and shows that deep low-frequency observations of galaxy clusters are fundamental for opening up a new part of parameter space in the study of non-thermal phenomena in galaxy clusters.

Analysis of path integrals at low temperature : Box formula, occupation time and ergodic approximation

description: We study the low temperature behaviour of path integrals for a simple one-dimensional model. Starting from the Feynman-Kac formula, we derive a new functional representation of the density matrix at finite temperature, in terms of the occupation times of Brownian motions constrained to stay within boxes with finite sizes. From that representation, we infer a kind of ergodic approximation, which only involves double ordinary integrals. As shown by its applications to different confining potentials, the ergodic approximation turns out to be quite efficient, especially in the low-temperature regime where other usual approximations fail.

description: Fractons are topological quasiparticles with limited mobility. While there exists a variety of models hosting these excitations, typical fracton systems require rather complicated many-particle interactions. Here, we discuss fracton behavior in the more common physical setting of classical kagome spin models with frustrated two-body interactions only. We investigate systems with different types of elementary spin degrees of freedom (three-state Potts, XY, and Heisenberg spins) which all exhibit characteristic subsystem symmetries and fracton-like excitations. The mobility constraints of isolated fractons and bound fracton pairs in the three-state Potts model are, however, strikingly different compared to the known type-I or type-II fracton models. One may still explain these properties in terms of type-I fracton behavior and construct an effective low-energy tensor gauge theory when considering the system as a 2D cut of a 3D cubic lattice model. Our extensive classical Monte-Carlo simulations further indicate a crossover into a low temperature glassy phase where the system gets trapped in metastable fracton states. Moving on to XY spins, we find that in addition to fractons the system hosts fractional vortex excitations. As a result of the restricted mobility of both types of defects, our classical Monte-Carlo simulations do not indicate a Kosterlitz-Thouless transition but again show a crossover into a glassy low-temperature regime. Finally, the energy barriers associated with fractons vanish in the case of Heisenberg spins, such that defect states may continuously decay into a ground state. These decays, however, exhibit a power-law relaxation behavior which leads to slow equilibration dynamics at low temperatures.
