description: The permafrost in Siberia (Russia) plays an important role for the global water cycle and climate change in the Earth system. In this study, data from satellite altimetry missions, hydrological models and GRACE are assimilated to retrieve a more realistic pattern of surface mass variations in Siberia. GRACE provides the integral mass variations with different spatial-temporal resolution depending on the applied filters and reduction models. We used the new release L2 products from GFZ (RL05a) and tested various filters. Geometrically, surface mass variations are determined based on satellite (radar/laser) altimetry tracking data (e.g. Jason-2, ICESat), where especially lake level variations are extracted. In addition, hydrological surface mass variations are obtained from hydrological water cycle models based on observations of precipitation, evapotranspiration and run-off data. We tried to quantify the individual signal contributions in Siberia and to consistently combine the various data to get a better estimate on how big the real permafrost change might be.

description: Areal precipitation estimation for fine temporal and spatial resolution is still a challenging task. Beside the fact that newly developed instrumentations, e.g. weather radar, provide valuable information with high spatial and temporal resolutions, they are subject to different sources of errors. On the other hand, recording rain gauges provide accurate point rainfall depth, but are still often poor in density. Equipping a car with a GPS device as well as sensors measuring rainfall makes it possible to implement cars on the streets as the moving rain gauges. Initial results from a modeling study assuming arbitrary measurement errors have shown that implementing a reasonable large number of inaccurate measurement devices (raincars) provide more reliable areal precipitations compared to the available rain gauge network. The purpose of this study is to derive relationships between sensor readings and rain rate in a laboratory and quantify the errors. Sensor readings involve wiper frequency and optical sensors which are on the cars to automate wiper activities. Besides, the influence of car speed on the sensor readings is investigated implementing a car-speed simulator. It has been observed that the manual wiper activity adjustment, according to front visibility, shows a strong relationship between rainfall intensity and wiper speed. Two optical sensors calibrated in laboratory showed a relatively strong relationship with the rain intensity recorded by a tipping bucket. A positive relationship between the velocity and the amount of water has been observed meaning that the higher the speed of a car, the higher the amount of water hitting the car. Additionally, some preliminary results of the field experiments are discussed.

description: We study minimum vertex cover problems on random α-uniform hypergraphs using two different approaches, a replica method in statistical mechanics of random systems and a leaf removal algorithm. It is found that there exists a phase transition at the critical average degree e/(α-1). Below the critical degree, a replica symmetric ansatz in the statistical-mechanical method holdsand the algorithm estimates a solution of the problem which coincide with that by the replica method. In contrast, above the critical degree, the replica symmetric solution becomes unstable and these methods fail to estimate the exact solution.These results strongly suggest a close relation between the replica symmetry and the performance of approximation algorithm.

description: We compute the trace of an endomorphism in equivariant bivariant K-theory for a compact group G in several ways: geometrically using geometric correspondences, algebraically using localisation, and as a Hattori-Stallings trace. This results in an equivariant version of the classical Lefschetz fixed-point theorem, which applies to arbitrary equivariant correspondences, not just maps.

description: Recent Cosmic Microwave Background (CMB) results from the Planck satellite, combined with previous CMB data and Hubble constant measurements from the Hubble Space Telescope, provide a constraint on the effective number of relativistic degrees of freedom of Neff=3.62^{+0.50}_{-0.48} at 95% CL. These new measurements provide a unique opportunity to place limits on models containing relativistic species at the decoupling epoch. Here we review the bounds or the allowed parameter regions in sterile neutrino models, hadronic axion models as well as on extended dark sectors with additional light species based on the latest Planck CMB observations.

description: The inhomogeneous fluctuations that underlie structure formation - galaxies and CMB hotspots - might have been seeded by quantum cosmological fluctuations, as magnified by some inflationary mechanism. The Halliwell-Hawking model for these, as a lower-energy semiclassical limit, is expected to be shared by many theories. E.g. an O((H/m_pl)^2) suppression of power at large scales results from this. This model contains/suppresses very many terms; we want a qualitative understanding of the meaning of these terms and of different regimes resulting from different combinations of them. I study this with toy models that have tractable mathematics: minisuperspace and, especially, relational particle mechanics. In the present Seminar, I consider in particular averaged terms with some lessons from Hartree-Fock approach to Atomic and Molecular Physics. One needs to anchor this on variational principles; treating the subsequent equations is a numerical venture.

description: The stochastic simulation of rainfall time series can profit from the application of multivariate models called copulas. One of these applications is based on events and copulas are used for modelling the joint behaviour of characteristics such as duration, amount, intensity and peak. Properly modelling the dependence structure between amount and duration is essential for reproducing the observed properties of all rainfall events, especially for the extreme ones. However, the non-exchangeable property between these two characteristics is a crucial aspect to be considered during the simulation. The aim of this work is to analyze the relationship between the bivariate behaviour of rainfall event characteristics and the extreme values. For this purpose, different statistics used to describe the dependence structure are estimated, namely Kendall’s Tau correlation coefficient, asymmetry measure and tail dependence coefficients. The extreme values are described by the Intensity-Duration-Frequency (IDF) curves. The properties of these curves should be related to the dependence structure. A total of 800 rainfall stations covering the whole extent of Germany are used for this analysis. The stations consist of high temporal resolution records, i.e. rainfall data every 5 minutes. The length of the available data ranges from 10 to 25 years. Continuous time series of rainfall events are identified for each station to estimate the bivariate measures. Extreme value analysis is performed to define the IDF curves. Furthermore the spatial variability of joint behaviour and extreme values is assessed.

description: A main challenge in cell therapies and other tissue regeneration approaches is to produce a therapeutically significant cell number. For expansion of mesenchymal stem cells (MSC) the cultivation on 2D plastic surfaces is still the conventional procedure, even though the culture conditions differ significantly from the 3D environment in vivo. Additionally, static amplification of MSC is a labour-intensive procedure. We therefore used a specialized rotating bed bioreactor in order to maximize ex vivo expansion of MSC. MSC were isolated from umbilical cord (UC) by explant method approach under xeno-free conditions. UC-MSC were thereafter expanded under dynamic conditions in a novel rotating bed bioreactor. The bioreactor system was designed to enable integration of sensors for online monitoring of various parameters (e.g. pH, pO2, pCO2) and hence, allow ensured cultivation under well controlled and reproducible conditions. Beside cell expansion, directed differentiation of MSC was also achieved in bioreactors. MSC lack the ability to grow in 3D direction and build functional tissue in vitro. Thus, it is necessary to seed and culture MSC on 3D matrices to obtain functional implants. For guided differentiation towards the osteogenic lineage, MSC were cultivated on ceramic porous matrices under dynamic conditions. Custom-made miniaturized perfusion bioreactors for parallel testing were designed and optimized for that purpose.

description: Plastics, or polymers, are low-cost materials that show good corrosion resistance, fair strength and low weight. This would make polymers excellent replacement materials for the heavy, expensive and corrosion sensitive metals used in most heat exchangers. This could result in reduced weight of vehicles improving the fuel economy, better functioning desalination plants for providing cheaper potable water and plenty of other possibilities. The only problem here is that polymers are thermal insulators. This problem can be solved by adding heat conducting materials as a filler in the polymer matrix, thus making a composite.
 This poster covers the basics of thermal conductivity in polymer composites.

description: Gravitational waves are now observed routinely. Therefore, data analysis has to keep up with ever improving detectors. One relatively new tool to search for gravitational wave signals in detector data are machine learning algorithms that utilize deep neuralnnetworks. The first successful application was able to differentiate time series strain data that contains a gravitational wave from a binary black hole merger from data that consists purely of noise. This work expands the analysis to signals from binary neutron star mergers, where a rapid detection is most valuable, as electromagnetic counterparts might otherwise be missed or not observed for long enough. We showcase many different architecture, discuss what choices improved the sensitivity of our search and introduce a new multi-rate approach. We find that the final algorithm gives state of the art performance in comparison to other search pipelines that use deep neural networks. On the other hand we also conclude that our analysis is not yet able to achieve sensitivities that are on par with template based searches. We report our results at false alarm rates down to ~30 samples/month which has not been tested by other neural network algorithms. We hope to provide information about useful architectural choices and improve our algorithm in the future to achieve sensitivities and false alarm rates that rival matched filtering based approaches on.

description: Classic taxonomy is a powerful tool for identifying animals based on morphology but has shown to be problematic on similar looking, cryptic species. A solution to this problem has been found within the bauplan of life, the DNA (deoxyribonucleic acid). DNA is used to create and regulate proteins. The structure of DNA has highly unique sections that are conserved within species, but diverse between species. One particular section, a 648 bp long fragment of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene, has become a popular barcode for species identification. Here, a new barcoding technique, character-based barcoding more similar to traditional approaches is tested. This thesis investigates whether CO1 is suitable as a single marker (a) or should be complemented by others (b). Performance of distance- and character-based barcoding (c) is evaluated and it is tested whether character-based barcoding can be used to identify cryptic species (d). In the first manuscript, CO1 sequences of endangered turtle species are compared (a). Having a reliable tool for species identification is an important asset in species protection surveillance. Variability within the barcode region is assessed and the utility of both distance- and character-based methods for species identification are evaluated (c). Odonata is an old order rich in species. As many species have evolved in a short time, it was observed that intra- and interspecific variety is overlapping in some sister groups. This observation made Odonata the ideal candidate for testing CO1 (a), ND1 (b), as well as distance- and character-based-barcoding (c) in the second manuscript. Ants are prime examples for high degrees of cryptic biodiversity due to complex population differentiation, hybridization and speciation processes. As combinations of multiple marker regions seemed to be a better approach to barcoding, three markers (CO1, 28S rDNA, rhodopsin) are tested (b) in the third manuscript. A combined, layered approach to character-based barcoding is evaluated and unique diagnostics specific to geolocations are identified (d). The results of all three studies show that combining multiple markers improves identification success. The character-based approach provides better identification in the tested animal groups. This method can be used to estimate presence, absence or frequency of cryptic species.

description: Introduction: Experiences and determinants connected with type 2 diabetes mellitus-associated erectile dysfunction (T2DMED) in health appointments are not well understood and infrequently reported. This systematic review was undertaken to synthesise evidence of the experiences, facilitators, and barriers around screening ED in men with T2DM during health service consultations. Methods: The review report was based on the guidelines provided by the Joanna Briggs Institute for conducting mixed-method systematic reviews. Eight electronic databases were searched, including Web of Science, Embase via Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCO, ProQuest, PubMed, PsychInfo via Ovid, MEDLINE via Ovid, Portal Garuda. Additionally, the review manually looked through the reference lists of the studies we included. Erectile dysfunction, type 2 diabetes mellitus, screening and barriers were initially used as keywords in the search strategy. All identified primary studies written in English and Bahasa Indonesia, and published between 2001 and 2022 were meticulously screened following an agreed set of inclusion criteria. Findings: Out of 3468 papers screened, only six were chosen for the review. These included three cross-sectional studies, two qualitative studies, and one mixed-method study. The study quality of the included studies was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. Based on the checklist criteria, the studies ranged between 5/10 to 9/10 in terms of quality. After synthesizing the findings, four main categories were identified including the willingness to discuss T2DMED, the barriers experienced and perceived, the limited understanding of T2DMED, and the support expected by men with T2DM. Discussion: Many men kept quiet about their struggles with T2DMED, hoping to bring it up as a topic of discussion during healthcare consultations. Barriers such as embarrassment, a sense of helplessness and reluctance to seek help, financial constraints, and dismissive healthcare professionals hindered them from addressing this issue. Both the participating men and healthcare professionals lacked a comprehensive understanding of T2DMED. Recommendations: It is important to provide education tailored to men's specific needs and improve awareness about T2DM-associated ED. Creating a more T2DMED-friendly environment could be a potential solution to increase early screening and management. Future research should investigate potential barriers that prevent HCPs from identifying and addressing T2MED since their absence in the identified studies highlights this need.

description: The diffeomorphism symmetry of general relativity leads in the canonical formulation to constraints, which encode the dynamics of the theory. These constraints satisfy a complicated algebra, known as Dirac's hypersurface deformation algebra. This algebra has been a long standing challenge for quantization. One reason is that discretizations, on which many quantum gravity approaches rely, generically break diffeomorphism symmetry. In this work we find a representation for the Dirac constraint algebra of hypersurface deformations in a formulation of discrete 3D gravity and for the flat as well as homogeneously curved sector of discrete 4D gravity. In these cases diffeomorphism symmetry can be preserved. Furthermore we present different versions of the hypersurface deformation algebra for the boundary of a simplex in arbitrary dimensions.

description: In this study, machine learning representation is introduced to evaluate the flexoelectricity effect in truncated pyramid nanostructure under compression. A Non-Uniform Rational B-spline (NURBS) based IGA formulation is employed to model the flexoelectricity. We investigate 2D system with an isotropic linear elastic material under plane strain conditions discretized by 45×30 grid of B-spline elements. Six input parameters are selected to construct a deep neural network (DNN) model. They are the Young's modulus, two dielectric permittivity constants, the longitudinal and transversal flexoelectric coefficients and the order of the shape function. The outputs of interest are the strain in the stress direction and the electric potential due flexoelectricity. The dataset are generated from the forward analysis of the flexoelectric model. 80% of the dataset is used for training purpose while the remaining is used for validation by checking the mean squared error. In addition to the input and output layers, the developed DNN model is composed of four hidden layers. The results showed high predictions capabilities of the proposed method with much lower computational time in comparison to the numerical model.

description: One of the most profound questions about the newly discovered class of low-density super-Earths is whether these exoplanets are predominately H2-dominated mini-Neptunes or volatile-rich worlds with gas envelopes dominated by H2O, CO2, CO, CH4, or N2. Transit observations of the super-Earth GJ 1214b rule out a cloud-free H2-dominated atmosphere, but are not able to determine whether the lack of deep spectral features is due to high-altitude clouds or the presence of a high mean molecular mass atmosphere. Here, we demonstrate that one can unambiguously distinguish between cloudy mini-Neptunes and volatile-dominated worlds based on the differences in the wing steepness and relative depths of water absorption features in moderate-resolution NIR transmission spectra (R~100). In a numerical retrieval study, we show for GJ 1214b that an unambiguous distinction between a cloudy H2-dominated atmosphere and cloud-free H2 atmosphere will be possible if the uncertainties in the spectral transit depth measurements can be reduced by a factor of ~3 compared to the published HST WFC3 and VLT transit observations. We argue that the required precision for the distinction may be achievable with currently available instrumentation by stacking 10-15 transit observations. We provide a scaling law that scales our quantitative results to other transiting super-Earths and Neptunes such as HD 97658b, 55 Cnc e, and GJ 436b. The analysis is performed using an improved version of our Bayesian atmospheric retrieval framework. The new framework not only constrains the gas composition and cloud/haze parameters, but also determines our confidence in having detected molecules and cloud/haze species through Bayesian model comparison. Using the Bayesian tool, we demonstrate quantitatively that the subtle transit depth variation in the Berta et al. (2012) data is not sufficient to claim the detection of water absorption.

description: Information-theoretical quantities such as statistical distinguishability typically result from optimisations over all conceivable observables. Physical theories, however, are not generally considered valid for all mathematically allowed measurements. For instance, quantum field theories are not meant to be correct or even consistent at arbitrarily small lengthscales. A general way of limiting such an optimisation to certain observables is to first coarse-grain the states by a quantum channel. We show how to calculate contractive quantum information metrics on coarse-grained equilibrium states of free bosonic systems (Gaussian states), in directions generated by arbitrary perturbations of the Hamiltonian. As an example, we study the Klein-Gordon field. If the phase-space resolution is coarse compared to h-bar, the various metrics become equal and the calculations simplify. In that context, we compute the scale dependence of the distinguishability of the quartic interaction.

description: Zizaene synthase (ZS) from Chrysopogon zizanioides (Poaceae) is the critical enzyme in the biosynthesis of the fragrant sesquiterpene khusimol, a major component of the vetiver essential oil used widely by the cosmetic industry. As reported previously, we heterologously and successfully ex-pressed the active ZS with a small ubiquitin-related modiﬁer (SUMO) fusion domain. In this study, we report the optimization of reaction conditions and determination of enzyme kinetics of ZS. Moreover, we investigate the catalytic speciﬁcity and reaction mechanisms with the ubiquitous (2E,6E)-farnesyl diphosphate (FDP) and with C10 and C15 prenyl diphosphate isomers. Catalytic promiscuity occurs with monoterpene substrates generating eight products that comprise acyclic, cyclic, and hydroxylated monoterpenes. In contrast, ZS is a high-ﬁdelity terpene cyclase when used with C15 isomer substrates, yielding as major products (Z)-β-farnesene (100%) for (2E,6Z)-FDP and (+)-zizaene (81.7%), β-acoradiene (12.8%), and (E)-β-farnesene (5.5%) for (2Z,6E)-FDP. Cyclization of the ubiquitous substrate (2E,6E)-FDP demonstrates a higher catalytic speciﬁcity, whereas the reaction proceeds via the acorenyl cation that generates (+)-zizaene (91.5%) and β-acoradiene (8.5%). Furthermore, catalytic speciﬁcity with (2E,6E)-FDP was stable in reactions tested at distinct pH and temperatures, suggesting a stable and eﬃcient closed conformation of the active site during catalysis. To understand such stability, open and closed structural conformations of ZS were modeled in silico and revealed putative residues in the active site and in the A-C and J-K surrounding loops, which could explain the high ﬁdelity of ZS.

description: Objective: The aim of the present study was to compare the bioavailability of calcium from 3 mineral waters with different concentrations of minerals with that of milk and a calcium supplement. Methods: A single-center, randomized controlled trial with a crossover design with 21 healthy men and women was conducted at the Institute of Food Science and Human Nutrition, Leibniz University Hannover. The participants consumed the 5 test products providing 300 mg of calcium each on 5 examination days with 1-week wash-out phases in between. Primary outcome variables were the area under the curve of serum calcium levels for 10-hour (AUC0–10h) and 24-hour urinary calcium excretion. Results: In all groups, no significant differences in the AUC0-10h of serum calcium levels as well as in the 24-hour urinary calcium excretion were observed. Likewise, mean changes in serum phosphate and urinary phosphate, as well as serum parathormone, showed no differences between the groups. Conclusion: Given an equivalent bioavailability of calcium in all test products, neither a high concentration of SO42− or of HCO3 influenced the bioavailability of calcium. Accordingly, the use of mineral water with high concentrations of calcium constitutes a calorie-free calcium source that can improve calcium supply.

description: Detection of the small molecule 25-hydroxyvitamin D (25(OH)D) as the most relevant marker for vitamin D supply suffers from a high variability of results using the current detection methods, such as high-performance liquid chromatography (HPLC) and immunoassays. A new detection approach using a highly specific aptamer directed against 25(OH)D was established in this study based on the target-induced dissociation (TID) sensing approach. In this work, the aptamer was investigated regarding its structural properties as well as its binding affinity by using microscale thermophoresis (MST). Moreover, complementary oligonucleotides were designed based on the aptamer structure and were evaluated in MST experiments. Binding experiments of immobilized aptamers were conducted in microarray experiments. It could be shown that the aptamer exhibited the usual B-DNA structure and did not form any G-quadruplexes. The design of complementary oligonucleotides for the TID assay identified a putative 25(OH)D binding site within the aptamer. The limit of detection of the established competitive assay was determined to be 5.4 nM, which sets the stage for the development of a biosensor system.

description: In this paper we investigate the nature of 27 star cluster candidates, most of them projected towards the Galactic anticentre. We derive fundamental parameters for 20 confirmed clusters, among these 7 are new identifications. Four of the remaining are uncertain cases that require deeper photometry to establish their nature, and 4 are probably field fluctuations. In addition, we provide a partial census of the open clusters towards the Galactic anticentre. We also include in this study some interesting objects outside the anticentre region, in the second and third Galactic quadrants, mainly in the Perseus and Outer arms. These clusters confirm the extension of the Outer arm along the third quadrant. We also point out that the embedded cluster FSR 486, at a distance of 7.2 +/- 1.3 kpc from de Sun, is projected on the line of sight of the Local Group irregular dwarf galaxy IC 10. Thus, part of the unusual properties of IC 10 may be explained by a Galactic contamination. We point out the importance of embedded clusters in tracing the spiral structure.

description: f(R)-theories of gravity are reviewed in the framework of the matter-antimatter asymmetry in the Universe. The asymmetry is generated by the gravitational coupling of heavy (Majorana) neutrinos with the Ricci scalar curvature. In order that the mechanism works, a time varying non-zero Ricci curvature is necessary. The latter is provided by f(R) cosmology, whose Lagrangian density is of the form {\cal L}(R)\sim f(R). In particular we study the cases f(R)\sim R+αR^n and f(R)\sim R^{1+ε}.
