description: This study suggests a Nonlinear Dynamic Inversion (ND!) autopilot for roll angle, lateral and longitudinal acceleration control of an aerial vehicle with both thrust vector and aerodynamic control. Sensitivity analysis of the autopilot under uncertainties, performance comparison with a linear autopilot, and a guided scenario with realistic measurement models are examined. The study uses two-loop cascaded structure with second-order reference models and proportional-integral controllers in each control channel. In addition, output redefinition is practiced to solve the non-minimum phase problem with NDI acceleration autopilots related to aerodynamic tail-controlled missile that is considered in the study.

description: Im Zuge der eigenen Arbeiten in dieser Habilitationsschrift ist es gelungen, zur Validierung des Post-Processings von Perfusionsbildgebung zur Nutzung im Rahmen multimodaler MRT-Bildgebung bei akuten cerebrovaskulären Ereignissen beizutragen. Die Erkenntnisse der eigenen Arbeiten integrieren sich hierbei gut in die zunehmende Validierung von Tmax als standardisiertem Perfusionsparameter zur Bestimmung der Penumbra in klinischen Studien. Ein einfacher klinischer Parameter zur Triage von MRT bei TIA-Patienten konnte weder in dieser Arbeit noch durch andere Arbeitsgruppen validiert werden. In Anbetracht der hohen Anzahl von TIA-Patienten, die ischämische Läsionen in der DWI aufweisen, und dem Wissen, dass das Rezidivrisiko bei Nachweis solcher Läsionen deutlich höher ist, rechtfertigt sich der Einsatz von multimodaler MRT bei TIA-Patienten. Das vormals als benigne eingeschätzte bildgebende Syndrom „total mismatch“ zeigt eine Rate von 39% ischämischer Läsionen im Verlauf, und sollte entsprechend behandelt werden. Umgekehrt kann bei selbstlimitierter Klinik und initial unauffälliger DWI auf eine Verlaufsbildgebung verzichtet werden.

description: The termination of endogenous sex hormone release is thought to account for increases in cardiovascular disease (CVD) incidence in postmenopausal women. Thus, hormone replacement therapy may be a preventive measure against cardiovascular disease. To date, most research has been focused on estrogen treatment, but the effects of progesterone, a vasoactive hormone with effects on the endothelium, have received less attention. Two progesterone receptor subtypes, nuclear and membrane, are known to enact the effects of progesterone in endothelial cells which mediate the release of nitric oxide (NO). There is also some evidence that the two subtypes function in a coordinated manner. The aims of this thesis study are to assess the effects of different concentrations of progesterone on endothelial cells and isolate the actions of the progesterone receptor subtypes. Outcomes of this study include migration and proliferation assays to assess endothelial cell function and Western blotting to quantify endothelial nitric oxide synthase expression and phosphorylation. Progesterone and the membrane progesterone receptor agonist were found to inhibit migration and proliferation of human umbilical vein endothelial cells (HUVECs), while progesterone alone or in combination with the membrane progesterone receptor agonist increased endothelial nitric oxide synthase (eNOS) phosphorylation in HUVECs after 24 hours of incubation. While increased eNOS phosphorylation is thought to be beneficial to HUVEC function, other factors released in the presence of progesterone or progesterone receptor agonists may be scavenging bioavailable NO, thus reducing the angiogenic potential of HUVECs.
VALIDATING THE EXPANDED FOOD SECURITY SCREENER AND HOME-DELIVERED MEAL PRIORITIZATION TOOL FOR ELIGIBLE INDIVIDUALS

Subjects: subject: Aging

description: The Expanded Food Security Screener (FSS-Exp) is a screening tool for determining food insecurity risk based on individuals’ physical, economic, and social access to food. The FSS-Exp is the only tool that provides a simple and quick method for identifying which home-delivered meal (HDM) applicants are most vulnerable. However, further testing is required to determine the tool’s validity when compared with health and food-related measures associated with food security. Therefore, this study aimed to validate the FSS-Exp and HDM prioritization tool using concurrent and construct validity methods. To evaluate the concurrent validity, we examined the correlations between the FSS-Exp and other health and food-related tools such as SF-36, MOS-SSS, SWFL, SNAQ, and DST, which were associated with economic food insecurity and physical limitation To determine construct validity using the known-groups approach, we compared those health and food-related scores among participants grouped by different access barriers to food (priority levels). The results showed that the FSS-Exp correlated moderately (r=0.20 to 0.33) with other “gold standard” measures: SF-36, MOS-SSS, and SWFL. Furthermore, our results showed that individuals categorized as priority level A and B had significantly lower mean scores than priority level E for the SF-36 (HRQL) summary measures (p<0.05), SWFL (p<0.05), and the tangible social support ( p<0.01). Thus, the FSS-Exp was shown to be a valid measure in identifying and prioritizing older adults with physical and/or economic access to food, which is especially important for HDM programs with limited resources experiencing increased demand for services. For HDM programs which exist to serve vulnerable older adults, using the validated FSS-Exp tool can help identify those who are most vulnerable and in need of immediate service.

description: Strong spin-orbit coupled 5d transition metal based ABO3 oxides, especially iridates, allow tuning parameters in the phase diagram and may demonstrate important functionalities, for example, by means of strain effects and symmetry-breaking, because of the interplay between the Coulomb interactions and strong spin-orbit coupling. Here, we have epitaxially stabilized high quality thin films of perovskite (Pv) CaIrO3. Film on the best lattice-matched substrate shows semi-metal-like characteristics. Intriguingly, imposing tensile or compressive strain on the film by altering the underlying lattice-mismatched substrates still maintains semi-metallicity with minute modification of the effective correlation as tensile (compressive) strain results in tiny increases (decreases) of the electronic bandwidth. In addition, magnetoresistance remains positive with a quadratic field dependence. This persistent semi-metal-like nature of Pv-CaIrO3 thin films with minute changes in the effective correlation by strain may provide new wisdom into strong spin-orbit coupled 5d based oxide physics.

description: The present work shows that a properly chosen ordering of operators can restore unitarity in anisotropic quantum cosmological models. Bianch V and Bianchi IX models with a perfect fluid are worked out. It has been shown that a transformation of coordinates takes the Hamiltonian to that of an inverse square potential which has equal deficiency indices and a self-adjoint extension is thus possible. It is also shown, although not detected clearly before, that isotropic models are also apt to violate the conservation of probability for a careless operator ordering.

description: Cancer treatment often lacks individual dose adaptation, contributing to insufficient efficacy and severe side effects. Thus, personalized approaches are highly desired. Although various analytical techniques are established to determine drug levels in preclinical models, they are limited in the automated real-time acquisition of pharmacokinetic profiles. Therefore, an online UHPLC-MS/MS system for quantitation of drug concentrations within 3D tumor oral mucosa models was generated. The integration of sampling ports into the 3D tumor models and their culture inside the autosampler allowed for real-time pharmacokinetic profiling without additional sample preparation. Docetaxel quantitation was validated according to EMA guidelines. The tumor models recapitulated the morphology of head-and-neck cancer and the dose-dependent tumor reduction following docetaxel treatment. The administration of four different docetaxel concentrations resulted in comparable courses of concentration versus time curves for 96 h. In conclusion, this proof-of-concept study demonstrated the feasibility of real-time monitoring of drug levels in 3D tumor models without any sample preparation. The inclusion of patient-derived tumor cells into our models may further optimize the pharmacotherapy of cancer patients by efficiently delivering personalized data of the target tissue.

description: Recently, the search for Majorana fermions (MFs) has become one of the most important and exciting issues in condensed matter physics since such an exotic quasiparticle is expected to potentially give rise to unprecedented quantum phenomena whose functional properties will be used to develop future quantum technology. Theoretically, the MFs may reside in various types of topological superconductor materials that is characterized by the topologically protected gapless surface state which are essentially an Andreev bound state. Superconducting doped topological insulators and topological crystalline insulators are promising candidates to harbor the MFs. In this review, we discuss recent progress and understanding on the research of MFs based on time-reversal-invariant superconducting topological materials to deepen our understanding and have a better outlook on both the search for and realization of MFs in these systems. We also discuss some advantages of these bulk systems to realize MFs including remarkable superconducting robustness against nonmagnetic impurities.

Chargino production via Z-Boson Decay in a Strong Electromagnetic Field

description: In the framework of MSSM the probability of $Z^0$-boson decay to charginos in a strong electromagnetic field, $Z^0\rightarrow χ^{+} χ^{-}$, is analyzed. The method of calculations employs exact solutions of relativistic wave equations for charginos in a crossed electromagnetic field. Analytic expression for the decay width $Γ(Z^{0}\rightarrow χ^{+} χ^{-})$ is obtained at an arbitrary value of the parameter $\varkappa=e m_Z^{-3}\sqrt{-(F_{μν}q^ν)^2}$, which characterizes the external-field strength $F_{μν}$ and $Z^0$-boson momentum $q^ν$. The process $Z^0\rightarrow χ^{+} χ^{-}$ is forbidden in vacuum for the case of relatively heavy charginos: $M_{χ^{\pm}} > m_Z/2$. However in an intense electromagnetic background this reaction could take place in the region of superstrong fields ($\varkappa > 1$).

The Plant Rhizosphere-Phyllosphere Connection: Analysis of root-associated Pseudomonas sp. -induced changes in Fruit Surface Phytochemical Profiles of Heirloom and Modern Tomato cultivars and effect on Salmonella enterica association

description: Despite more rigorous food safety regulation for fruit and vegetable production, foodborne illnesses and massive food recalls have resulted from the enteropathogen Salmonella enterica on Solanum lycopersicum (tomato) fruits. While some phytochemical profiles have been studied on modern cultivars in regards to minimizing Salmonella-plant association, little research has been done on heirloom varieties. The interaction between the plant rhizosphere and phyllosphere remains understudied and the inoculation of plants with plant-growth promoting rhizobacteria (PGPR) can modify phyllosphere components of plants including fruit properties. No research exists on whether PGPR colonization of tomato plant roots can alter the fruit’s phytochemical profile to affect Salmonella association. Through several chemical and microbial analyses, I investigated the Salmonella association with fruit of modern and heirloom cultivars, as well as the impact of PGPR inoculation on this system. In Chapter 3, I assessed fruit of modern and heirloom varieties, and explored possible associations between Salmonella growth in fruit surface washes and total sugar quantifications, citric acid and (for heirloom varieties) the fatty acid profiles. Microbial counts differed from variety to variety and heirloom varieties demonstrated higher levels of sugars and citric acid compared to modern varieties. Total sugar quantifications and citric acid were correlated with microbial counts in heirloom varieties, but not in modern varieties. Chapter 4 focuses on the effects of inoculating the heirloom varieties with a PGPR in the genus Pseudomonas sp.on the fruit surface phytochemical profile and changes in microbial association. Differing trends between the PGPR inoculated and non-inoculated groups were seen where citric acids were correlated with Salmonella association for the non-PGPR group, but not for the PGPR inoculated group. For both the PGPR inoculated and non-inoculated groups, we measured a high degree of variation between the cultivars for the phytochemical profiles, and for both groups hexadecanoic acid was negatively correlated with microbial counts. This study furthers the understanding of the relationship between tomato fruit phytochemistry and Salmonella association, as well as the effects of PGPR on modifying tomato fruit phytochemistry. These findings can help manage and improve the pre- and post-harvest food safety of tomato fruit.

description: Environmental protection efforts can only be effective in the long term with a reliable quantification of pollutant gas emissions as a first step to mitigation. Measurement and analysis strategies must permit the accurate extrapolation of emission values. We systematically analyzed the added value of applying modern machine learning methods in the process of monitoring emissions from naturally ventilated livestock buildings to the atmosphere. We considered almost 40 weeks of hourly emission values from a naturally ventilated dairy cattle barn in Northern Germany. We compared model predictions using 27 different scenarios of temporal sampling, multiple measures of model accuracy, and eight different regression approaches. The error of the predicted emission values with the tested measurement protocols was, on average, well below 20%. The sensitivity of the prediction to the selected training dataset was worse for the ordinary multilinear regression. Gradient boosting and random forests provided the most accurate and robust emission value predictions, accompanied by the second-smallest model errors. Most of the highly ranked scenarios involved six measurement periods, while the scenario with the best overall performance was: One measurement period in summer and three in the transition periods, each lasting for 14 days.

We find that the Q balls would be the dark matter in the parameter region different from that for gravitino dark matter. In particular, the Q ball is a good dark matter candidate for low reheating temperature, which may be suitable for the Affleck-Dine baryogenesis and/or nonthermal leptogenesis. Dark matter Q balls are detectable by IceCube-like experiments in the future, which is the peculiar feature compared to the case of gravitino dark matter.

description: We present a multi-wavelength analysis of eleven Sunyaev Zel'dovich effect (SZE)-selected galaxy clusters (ten with new data) from the Atacama Cosmology Telescope (ACT) southern survey. We have obtained new imaging from the Large APEX Bolometer Camera (345GHz; LABOCA) on the Atacama Pathfinder EXperiment (APEX) telescope, the Australia Telescope Compact Array (2.1GHz; ATCA), and the Spectral and Photometric Imaging Receiver (250, 350, and $500\,\rmμm$; SPIRE) on the Herschel Space Observatory. Spatially-resolved 345GHz SZE increments with integrated S/N > 5 are found in six clusters. We compute 2.1GHz number counts as a function of cluster-centric radius and find significant enhancements in the counts of bright sources at projected radii $θ< θ_{2500}$. By extrapolating in frequency, we predict that the combined signals from 2.1GHz-selected radio sources and 345GHz-selected SMGs contaminate the 148GHz SZE decrement signal by ~5% and the 345GHz SZE increment by ~18%. After removing radio source and SMG emission from the SZE signals, we use ACT, LABOCA, and (in some cases) new Herschel SPIRE imaging to place constraints on the clusters' peculiar velocities. The sample's average peculiar velocity relative to the cosmic microwave background is $153\pm 383\,\rm km\,s^{-1}$.

description: Exposure of phosphatidylserine (PS) in the outer leaflet of the plasma membrane is induced by infection with several members of the Alphaherpesvirinae subfamily. There is evidence that PS is used by the equine herpesvirus type 1 (EHV-1) during entry, but the exact role of PS and other phospholipids in the entry process remains unknown. Here, we investigated the interaction of differently charged phospholipids with virus particles and determined their influence on infection. Our data show that liposomes containing negatively charged PS or positively charged DOTAP (N-[1-(2,3-Dioleoyloxy)propyl]-N,N,N-trimethylammonium) inhibited EHV-1 infection, while neutral phosphatidylcholine (PC) had no effect. Inhibition of infection with PS was transient, decreased with time, and was dose dependent. Our findings indicate that both cationic and anionic phospholipids can interact with the virus and reduce infectivity, while, presumably, acting through different mechanisms. Charged phospholipids were found to have antiviral effects and may be used to inhibit EHV-1 infection.

description: Anaerobic digestion (AD) is a sustainable waste-to-energy method for converting organic waste to methane. Various pre-treatment of food waste (FW) with free nitrous acid (FNA; pKa=3.25) were used to stabilize FW and mitigate obstacles (odor in FW storage and pathogenic bacteria) in AD. FNA concentrations ranging from 0-5 mg-N/L were tested in this study at pH ranging from 3-5.5, and volatile solids (VS) content of 16.8-135 g/L. Solubilization of organic material, inhibition of N-related biological processes, and control of problematic microorganisms, including sulfate-reducing bacteria (SRB) and pathogenic bacteria, were compared with the groups without FNA addition. At the tested pH (3, 4, and 5) and concentrations of FNA (0.3-5.0 mg-N/L), FNA addition showed inhibition to N-related biological processes contributing to a consistent FNA concentration over the 72 hours pre-treatment. However, it did not enhance the solubilization of organic materials compared with control group without FNA addition. The FNA concentration affected the bacterial inhibition of SRB. As the concentration of FNA increased from 0.3-5.0 mg-N/L, so did SRB inhibition. Similarly, increasing FNA concentration resulted in a faster reduction (2.5 logs within 4 hours) in pathogenic bacteria compared with the group without FNA addition. Overall, a shorter pre-treatment time (<24 hours) is recommended for using low FNA concentration (1.5 mg N/L) and high solids content (> 80.57 g /L), as the effective FNA concentration cannot be maintained for longer due to NO2- and bioavailable organic carbon consumption by N-related or other microorganisms that remain active or recoverable under the added FNA concentration.

The standard improvement condition using Schroedinger functional boundary conditions is employed at constant physics for a range of couplings relevant for simulations at lattice spacings of ~ 0.09 fm and below. We define the improvement condition projected onto the zero topological charge sector of the theory, in order to avoid the problem of possibly insufficient tunneling between topological sectors in our simulations at the smallest bare coupling. An interpolation formula for c_A(g_0^2) is provided together with our final results.

Although many numerical and experimental studies investigated the capabilities of HLFC, it is still challenging to consider the technology in a conceptual aircraft design phase. The present work focuses on integrating novel methodology for HLFC in the conceptual design with overall aircraft design to investigate the potential of HLFC on performance improvement of commercial aircraft. In particular, three commercial aircraft are studied and optimized aerodynamically for turbulent and HLFC applications, correlations are derived.

description: Quasi-Periodic Oscillations (QPOs) observed in the X-ray flux emitted by accreting black holes, are associated to phenomena occurring near the horizon. Future very large area X-ray instruments will be able to measure QPO frequencies with very high precision, thus probing this strong-field region. By using the relativistic precession model, we show the way in which QPO frequencies could be used to test general relativity against those alternative theories of gravity which predict deviations from the classical theory in the strong-field regime. We consider one of the best motivated strong-curvature corrections to general relativity, namely the Einstein-Dilaton-Gauss-Bonnet theory, and show that a detection of QPOs with the expected sensitivity of the proposed ESA M-class mission LOFT would set the most stringent constraints on the parameter space of this theory.

description: Quantitative sediment analyses performed in the laboratory are often used throughout archaeological excavations to critically reflect on-site stratigraphic delineation. Established methods are, however, often time-consuming and expensive. Recent studies suggest that systematic image analysis can objectivise the delineation of stratigraphic layers based on fast quantitative spectral measurements. The presented study examines how these assumptions prevail when compared to modern techniques of sediment analysis. We examine an archaeological cross-section at a Bronze Age burial mound near Seddin (administrative district Prignitz, Brandenburg, Germany), consisting of several layers of construction-related material. Using detailed on-site descriptions supported by quantitatively measured sediment properties as a measure of quality, we compare clustering results of (i) extensive colour measurements conducted with an RGB and a multispectral camera during fieldwork, as well as (ii) selectively sampled sedimentological data and (iii) visible and near infrared (VIS-NIR) hyperspectral data, both acquired in the laboratory. Furthermore, the influence of colour transformation to the CIELAB colour space (Commission Internationale de l’Eclairage) and the possibilities of predicting soil organic carbon (SOC) based on image data are examined. Our results indicate that quantitative spectral measurements, while still experimental, can be used to delineate stratigraphic layers in a similar manner to traditional sedimentological data. The proposed processing steps further improved our results. Quantitative colour measurements should therefore be included in the current workflow of archaeological excavations.

Salvaging Citizenship: Key West’s Afro-Bahamians, Caribbean Emancipation, and U.S. Naturalization Law
Creators: name: McGrady, Madeleine Marie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Between 1833 and 1840, Afro-Bahamian mariner Thomas Romer faced arrest at least four times on Key West. In February 1832, ten years after the U.S. had acquired the island, Florida’s legislature reacted to domestic slave rebellions by prohibiting the settlement of free people of color in the territory. Established on Key West by 1831, Romer did not fall under the law’s jurisdiction and could come and go as his seafaring work demanded. At least, that was how Monroe County’s court interpreted the law. On the island, responses to Florida’s Negro Seamen Act varied. Although some white Key Westers pursued the arrest of foreign-born people of color who arrived to the burgeoning port, arrests of mariners on Key West occurred less frequently than in other southern port cities. The salvage industry overshadowed slavery on Key West, and white elites prioritized the island’s commercial health over the possible contagion of abolitionism.       Seeking to monopolize the Gulf of Mexico’s lucrative salvage industry, white Key West merchants depended on the wrecking expertise of Afro-Bahamians and often defended their presence on the island. Romer leveraged his reputation, knowledge of the court system, and connections with elite white merchants to protect his claims to belonging on Key West and evade deportation throughout the 1830s. Through local court records, newspaper accounts, and census data, Romer’s case demonstrates the relational nature of antebellum citizenship. After the U.S. Civil War, Romer petitioned for the 1870 Naturalization Act which granted citizenship access to Afro-descended immigrants. Floating in the eddies of empires, Key West’s cosmopolitan community impacted federal U.S. naturalization law and ideas about who belonged in the reconciled nation’s body politic.

description: We study the optimal control problem of minimizing the convergence time in the discrete Hegselmann--Krause model of opinion dynamics. The underlying model is extended with a set of strategic agents that can freely place their opinion at every time step. Indeed, if suitably coordinated, the strategic agents can significantly lower the convergence time of an instance of the Hegselmann--Krause model. We give several lower and upper worst-case bounds for the convergence time of a Hegselmann--Krause system with a given number of strategic agents, while still leaving some gaps for future research.

description: Neutrinoless double beta decay allows to constrain lepton number violating extensions of the standard model. If neutrinos are Majorana particles, the mass mechanism will always contribute to the decay rate, however, it is not a priori guaranteed to be the dominant contribution in all models. Here, we discuss whether the mass mechanism dominates or not from the theory point of view. We classify all possible (scalar-mediated) short-range contributions to the decay rate according to the loop level, at which the corresponding models will generate Majorana neutrino masses, and discuss the expected relative size of the different contributions to the decay rate in each class. Our discussion is general for models based on the SM group but does not cover models with an extended gauge. We also work out the phenomenology of one concrete 2-loop model in which both, mass mechanism and short-range diagram, might lead to competitive contributions, in some detail.

description: Electric variable RPM rotors are increasingly being used for propulsion and control of unmanned air vehicles. As these vehicles scale to carry heavier payloads of 50 to 400 lbs (20 to 180 kgs) in the group 2 and 3 UAS category, there are concerns about their aerodynamic performance and handling quality degradation. Therefore, there is a need to develop a systematic experimental testing procedure to measure loads on these systems to evaluate performance and augment Computational Fluid Dynamic (CFD) validation tools. In this work, a universal electric powered test rig is designed and fabricated for hover and wind tunnel tests of open and shrouded rotors. Steady hover results are validated using blade element momentum theory. These predictions incorporate an empirical correction approach in conjunction with an interpolation scheme to capture Reynolds number variation along the span of the blade and variation with RPM. Results show good agreement with the interpolation method for the low Reynolds number rotor tested (Re_tip<500,000). For the variable RPM rotor, transient step and chirp inputs are also presented. System identification showed linear frequency responses between thrust and torque with RPM and RPM-square in hover. Therefore, when modeling this rotor, steady inflow appears adequate in the frequency range of interest (0.4 to 60 rad/sec). In addition to an open rotor, the electric motor-rotor test stand was used to test a shrouded rotor in hover and forward flight to systematically compare performance results. Test data showed the shrouded rotor gained 15% thrust for the same power in hover with the best configuration. For low speed forward flight, lift-to-drag ratio was found to increase by 8 to 10% for the shrouded rotor system over the isolated rotor.

description: Deepening quantitative survey questions through focus group discussions can shine a light on the deeper understandings of individuals about social citizenship, and also demonstrate how ambivalent and multidimensional attitudes are about such social citizenship in Europe. This paper presents the methodology, the research process and preliminary findings from a series of focus group discussions on the future of European social citizenship that were conducted over the course of 2022 in four European countries: Germany, the Netherlands, Poland, and Spain, involving a total of 134 participants. Importantly, as part of the focus groups, we also collected quantitative survey evidence via a short questionnaire handed out to participants before the discussion, allowing us to compare our qualitative data with quantitative evidence. The focus groups covered three topical areas: 1) support for government redistribution broadly understood (and different meanings thereof), 2) the relationship between the national and EU levels in financing and providing social policy, and 3) inequalities in access to social rights and how to address them. To summarize the core findings of our preliminary analysis: Focus group participants were generally supportive of strengthening the social dimension of the EU (as quantitative surveys have also shown), but the qualitative data also revealed a significant degree of skepticism regarding the ability of the EU in dealing with the current series of large-scale crises. Participants also noted persistent inequalities in accessing social rights, which appear to be correlated to socio-economic status. A main driving force of these inequalities is likely to be a prevailing information deficit, in particular regarding the initiatives of the EU in the social domain.
On the signature of the baryon-dark matter relative velocity in the two and three-point galaxy correlation functions

description: We develop a configuration-space picture of the relative velocity between baryons and dark matter that clearly explains how it can shift the BAO scale in the galaxy-galaxy correlation function. The shift occurs because the relative velocity is non-zero only within the sound horizon and thus adds to the correlation function asymmetrically about the BAO peak. We further show that in configuration space the relative velocity has a localized, distinctive signature in the three-point galaxy correlation function (3PCF). In particular, we find that a multipole decomposition is a favorable way to isolate the relative velocity in the 3PCF, and that there is a strong signature in the l=1 multipole for triangles with 2 sides around the BAO scale. Finally, we investigate a further compression of the 3PCF to a function of only one triangle side that preserves the localized nature of the relative velocity signature while also nicely separating linear from non-linear bias. We expect that this scheme will substantially lessen the computational burden of finding the relative velocity in the 3PCF. The relative velocity's 3PCF signature can be used to correct the shift induced in the galaxy-galaxy correlation function so that no systematic error due to this effect is introduced into the BAO as used for precision cosmology.

description: Many dimensionality and model reduction techniques rely on estimating dominant eigenfunctions of associated dynamical operators from data. Important examples include the Koopman operator and its generator, but also the Schrödinger operator. We propose a kernel-based method for the approximation of differential operators in reproducing kernel Hilbert spaces and show how eigenfunctions can be estimated by solving auxiliary matrix eigenvalue problems. The resulting algorithms are applied to molecular dynamics and quantum chemistry examples. Furthermore, we exploit that, under certain conditions, the Schrödinger operator can be transformed into a Kolmogorov backward operator corresponding to a drift-diffusion process and vice versa. This allows us to apply methods developed for the analysis of high-dimensional stochastic differential equations to quantum mechanical systems.

description: Self-healing inflatable structures are becoming increasingly appealing for space applications as combining their high packing efficiency and light weight with autonomous damage recovery would result in higher safety and reliability and lower costs. Nevertheless, a deeper knowledge of the effects of space environment on self-healing materials is needed. In this work self-healing polymers are characterised before and after space conditioning to determine how space environment can affect their properties. It is observed that some factors significantly modify part of their properties, and the obtained results can help with the determination of actual behaviour and lifetime of these materials in space.
