description: Hybrid quantum information protocols are based on local qubits, such as trapped atoms, NV centers, and quantum dots, coupled to photons. The coupling is achieved through optical cavities. Here we demonstrate far-field optimized H1 photonic crystal membrane cavities combined with an additional back reflection mirror below the membrane that meet the optical requirements for implementing hybrid quantum information protocols. Using numerical optimization we find that 80% of the light can be radiated within an objective numerical aperture of 0.8, and the coupling to a single-mode fiber can be as high as 92%. We experimentally prove the unique external mode matching properties by resonant reflection spectroscopy with a cavity mode visibility above 50%.

description: Runaway stars produce shocks when passing through interstellar medium at supersonic velocities. Bow shocks have been detected in the mid-infrared for several high-mass runaway stars and in radio waves for one star. Theoretical models predict the production of high-energy photons by non-thermal radiative processes in a number sufficiently large to be detected in X-rays. To date, no stellar bow shock has been detected at such energies. We present the first detection of X-ray emission from a bow shock produced by a runaway star. The star is AE Aur, which was likely expelled from its birthplace by the encounter of two massive binary systems and now is passing through the dense nebula IC 405. The X-ray emission from the bow shock is detected at 30" to the northeast of the star, coinciding with an enhancement in the density of the nebula. From the analysis of the observed X-ray spectrum of the source and our theoretical emission model, we confirm that the X-ray emission is produced mainly by inverse Compton upscattering of infrared photons from dust in the shock front.

description: The distribution function $f(ψ)$ of magnetic flux $ψ$ in plasmoids formed in high-Lundquist-number current sheets is studied by means of an analytic phenomenological model and direct numerical simulations. The distribution function is shown to follow a power law $f(ψ)\simψ^{-1}$, which differs from other recent theoretical predictions. Physical explanations are given for the discrepant predictions of other theoretical models.

description: We study the spectral properties of the unresolved cosmic X-ray background (CXRB) in the 1.5-7.0 keV energy band with the aim of providing an observational constraint on the statistical properties of those sources that are too faint to be individually probed. We made use of the Swift X-ray observation of the Chandra Deep Field South complemented by the Chandra data. Exploiting the lowest instrument background (Swift) together with the deepest observation ever performed (Chandra) we measured the unresolved emission at the deepest level and with the best accuracy available today. We find that the unresolved CXRB emission can be modeled by a single power law with a very hard photon index Gamma=0.1+/-0.7 and a flux of 5(+/-3)E-12 cgs in the 2.0-10 keV energy band (1 sigma error). Thanks to the low instrument background of the Swift-XRT, we significantly improved the accuracy with respect to previous measurements. These results point towards a novel ingredient in AGN population synthesis models, namely a positive evolution of the Compton-thick AGN population from local Universe to high redshift.

description: We construct a minimal model within the general class of Pyramid Schemes, which is consistent with both supersymmetry breaking and electroweak symmetry breaking. In order to do computations, we make unjustified approximations to the low energy Kähler potential. The phenomenological viability of the resultant mass spectrum is then examined and compared with current collider limits. We show that, for certain regimes of parameters, the Pyramid Scheme can accommodate the current collider mass constraints on physics beyond the standard model with a tree-level light Higgs mass near 125 GeV. However, in this regime the model exhibits a little hierarchy problem, and one must permit fine-tunings that are generically 5%.

description: The Qweak experiment aims to measure the weak charge of the proton to 4% via the parity-violating asymmetry ($\sim$-200 ppb) in elastic e+p scattering. The scattering rate is largely influenced by five beam parameters: horizontal position (X), angle (X'), vertical position (Y), angle (Y'), and beam energy (E). Changes in these parameters when the beam polarization is reversed will create a false asymmetry. To measure the detector sensitivities, we modulate X, X', Y, Y' using four air-core dipoles in the Hall C beamline as well as beam energy with a superconducting RF cavity. Linear regression is then used to remove the false asymmetry. The beam modulation system has also proven valuable for tracking changes in the Hall-C beamline optics including dispersion at the target.

description: The paper is concerned with various ways of analysing the subjective assessment of displaying digital signage content. In the beginning the brief description of the signage system evolution is described and next, the carried out ex-periment is depicted. The preferences of the 32 subjects were obtained using pairwise comparisons of the designed screen formats. Then the priorities were derived by applying the Analytic Hierarchy Process (Saaty, 1977; 1980) framework. The gathered data were modelled and analysed by means of the analysis of variance, multiple regression, conjoint and factor analysis. The results suggest that the application of different methods of preference analysis may provide additional information, which could facilitate more in-depth understanding of the given preference structure.

description: We propose a solution concept for a class of extensive form games with ambiguity. Specifically we consider multi-stage games. Players have CEU preferences. The associated ambiguous beliefs are revised by Generalized Bayesian Updating. We assume individuals take account of possible changes in their preferences by using consistent planning. We show that if there is ambiguity in the centipede game it is possible to sustain 'cooperation' for many periods as part of a consistent-planning equilibrium under ambiguity. In a non-cooperative bargaining game we show that ambiguity may be a cause of delay in bargaining.

description: This is a pre-registration document for our planned research in IndiaBackground and explanation of rationale.There is growing literature that examines the role of political brokers in developing democracies. There have been recent studies in India and Argentina to show slum leaders take up resident problems, themselves rooted and having a reputation within the slum community. This makes them attractive to political parties. Slum leaders offer a way for residents to broker goods and services within their community (Auerbach and Thachil, 2018; Paniagua, 2022). Much of the seminal work on slums and their informal leaders focused on cities in Latin America. Classic studies are Ray (1969), Cornelius (1975), Perlman (1976) and Stokes (1995) who study Caracas, Mexico City, Rio de Janeiro, and Lima respectively. Research also considers the presence of associational activity, where slum level councils provide a structure for informal governance. This has been shown to be the case in barrios in Venezuela (Ray, 1969) and in Peru and Ecuador where neighbourhood associations advance the security and welfare of local residents (Dosh, 2010). Development committees and associations in India’s slums have been found to be able to exert significant efforts to improve local conditions from within. They serve as valuable partners in development projects that build local capacities in quotidian governance (Auerbach, 2017). Professor Mark Pennington at King’s College London and the Centre for the Study of Governance and Society and the John Templeton Foundation funded project ‘The Ideal of Self Governance” considers circumstances where governance institutions arising from a ‘bottom-up’ or ‘polycentric’ process of evolution are better placed to cope with these constraints than a reliance on formal governments and centralised political authority (2013). Research around self-governance and community-based interest groups has also been undertaken around disaster management (Chamlee-Wright and Storr, 2009; Chamlee-Wright, 2010; Chamlee-Wright and Storr, 2011).This research explores the emergence of brokers in different slum types in Delhi, India and how these brokers build a following from the local residents. This research will explore the characteristics that separate brokers from other residents in their neighbourhoods.This research focuses on brokers as informal slum leaders. We seek to investigate the origins of hierarchy in clientelist spaces and study the processes through which informal leaders emerge within different slum types.

description: We analyze Chandra observations of diffuse soft X-ray emission associated with a complete sample of 3CR radio galaxies at z < 0.3. In this paper we focus on the properties of the spectroscopic sub-classes of high excitation galaxies (HEGs) and broad line objects (BLOs). Among the 33 HEGs we detect extended (or possibly extended) emission in about 40% of the sources; the fraction is even higher (8/10) restricting the analysis to the objects with exposure times larger than 10 ks. In the 18 BLOs, extended emission is seen only in 2 objects; this lower detection rate can be ascribed to the presence of their bright X-ray nuclei that easily outshine any genuine diffuse emission. A very close correspondence between the soft X-ray and optical line morphology emerges. We also find that the ratio between [O III] and extended soft X-ray luminosity is confined within a factor of 2 around a median value of 5. Both results are similar to what is seen in Seyfert galaxies. We discuss different processes that could explain the soft X-ray emission and conclude that the photoionization of extended gas, coincident with the narrow line region, is the favored mechanism.

The role of colour preattentive processing in human-computer interaction task efficiency: a preliminary study

Year: 2012
Subjects: subject: Human-Computer Interaction (cs.HC)

description: In this paper, results of experimental research on the preattentive mechanism in the human-computer interaction (HCI) were presented. Fifty four subjects were asked to find interface elements from various panel structures. The arrangements were differentiated by their orientation (vertical, horizontal), colour pattern (ordered, unordered) and object background colours (green-blue, green-red, blue-red). The main finding of the study generally confirms the profits provided by the visual preattentive processing of the colour feature in graphical panel operation efficiency. However, the vertical way of arranging the items in search layouts resulted in decreasing the preattentive effect related to the item background colour. In regular, chessboard-like patterns of different coloured items, the effect of the early vision was less salient than in the case of structures with randomly dispersed colours. The reported results can help in designing efficient graphical user-computer interfaces in many interactive information systems.

title: Development and characterization of two-dimensional metallic magnetic calorimeter arrays for the high-resolution X-ray spectroscopy
Creators: name: Hengstler, Daniel
Publisher: name: Heidelberg University Library
Year: 2017

description: In the framework of this thesis the new two-dimensional detector array maXs30 was developed, fabricated and characterized. It is optimized for high-resolution X-ray
spectroscopy in the energy range up to 30 keV and consists of 8x8 individual metallic magnetic calorimeters. These detectors combine the good energy resolution of crystal spectrometers and the large energy bandwidth of semiconductor detectors and measure the energy of each absorbed photon by the resulting temperature change. This change is converted to a change of magnetization by the paramagnetic alloy Ag:Er, which is read out by sensitive SQUID magnetometers. The detector can be mounted on the side arm of a mobile dry dilution refrigerator and a new 32 channel acquisition system has been developed for this array. The intrinsic energy resolution of the maXs30 detector was measured to be 7.9 eV (FWHM) and a resolving power of almost 3000 was achieved for X-rays with an energy of 60 keV. The complete maXs system was successfully tested during several experiments at the heavy ion storage ring ESR at the GSI, where the Lyman series of Xe53+ and the Balmer series of U89+ were investigated.
Scale dependent non-Gaussianities in the CMB data identified with Minkowski Functionals and Scaling Indices

description: In order to test for non-Gaussianities with respect to scale-dependencies we use so-called surrogate maps, in which possible phase correlations of the Fourier phases of the original WMAP data and simulations, respectively, are destroyed by applying a shuffling scheme to the maps. A statistical comparison of the original maps with the surrogate maps then allows to test for the existence of higher order correlations in the original maps, also and especially on well-defined Fourier modes. Using Minkowski functionals as an image analysis technique we calculate the deviation between the original data and 500 surrogates for different hemispheres in the sky and find ecliptic hemispherical asymmetries between northern and southern ecliptic sky. We find strong deviations from Gaussianity in the WMAP data when considering the low-l range with l = [2,20]. The analysis technique of the scaling indices leads to a slightly lower deviation. Although the underlying foreground reduction methods of the maps differ from each other, we find similar results for the WMAP 7yr ILC map and the WMAP 7yr (needlet-based) NILC map in the low-l range. Our results point once more to a cosmological nature of the signal. For a higher l range with l = [120,300] the results differ between the two image analysis techniques and between the two maps which makes an intrinsic nature of the signal on this l range less likely. When we decrease the size of the analysed sky regions for the low-l study, we do not find signatures of NG in the northern sky. In the south we find individual spots which show deviations from Gaussianity. In addition, we investigate non-Gaussian CMB simulations that depend on the f_NL parameter of the local type. These simulations cannot account for the detected signatures on the low-l range.

description: Alterung ist ein hoch komplexes und streng reguliertes Zusammenspiel zwischen genetischen und umweltlichen Faktoren in lebenden Organismen. Auf zellulärer Ebene ist der Alterungsprozess begleitet von zahlreichen Modifizierungen, einschliesslich Veränderungen der posttranslationalen Proteinmodifikationen (PTM). Mit einem quantitativen proteomischen Ansatz ist das Ziel dieser Arbeit unser jetziges Verständnis von Alterung in der Knochenmarknische zu erweitern, mit einem Fokus auf die Rolle der PTM. In der folgen den Arbeit wird das menschliche Knochenmark in sechs Zellsubpopulationen unterteilt. Veränderungen des Proteoms wurden für 59 Spender untersucht, deren Altersunterschied 40 Jahre beträgt. Modifizierte Proteine wurden identifiziert durch Kombinierung von Masse-tolerant und Standard Datenbank Suchmethoden. Die Analyse zeigte, dass PTM im Knochenmarkproteom weitverbreitet und abhängig vom Zelltyp sind. Zu den unterschiedlichen modifizierten Proteinen gehören Proteine der Glykolyse und Proteine der heterogenen Ribonukleinfamilie. Zusätzlich zeigte die altersabhängige Assoziierungsanalyse der modifizierten Proteine, dass das Modifizierungsniveau für die Mehrheit der modifizierten Proteine während des Alterungsprozesses stabil blieben. Die acetylierten Proteine in den hämatopoetischen Progenitoren korrelierten negativ mit dem Alter, was vielleicht auf das reduzierte Differenzierungspotential der Stammzellen zurückzuführen war. Koregulierungen der modifizierten Proteine während des Alterungsprozesses wurden ebenfalls in den Knochenmarkzellen, vor allem aber in den hämatopoetischen Progenitoren beobachtet. Die Ergebnisse dieser Arbeit könnten als Basis dienen für die Aufklärung biologischer Mechanismen, in denen die beschriebenen PTM die altersassoziierten Prozesse in unterschiedlichen Knochenmarkzellen regulieren.
title: Estimation of Soil Water Dynamics Based on Hydrogeophysical Measurements
Creators: name: Jaumann, Stefan
Publisher: name: Heidelberg University Library
Year: 2018

description: Quantitative understanding of soil water movement is essential to develop methods that allow for a more sustainable use of limited freshwater resources.
In this study, methods are developed that allow to estimate the spatial distribution of these materials, their effective soil hydraulic material properties, and the effect of unrepresented model errors on these properties.
To acquire the necessary data, a 2D subsurface architecture (ASSESS) was forced with a fluctuating groundwater table. The resulting hydraulic dynamics were essentially monitored with time domain reflectometry (TDR) and ground-penetrating radar (GPR).
Based on the TDR data, the effect of unrepresented model errors on estimated soil hydraulic material properties is analyzed with a structural error analysis. This method compares inversions of increasingly complex models, since the required model complexity for a consistent description of the measurement data is application-dependent and unknown a priori. It is demonstrated that the method can indicate unrepresented model errors and quantify their effects on the resulting material properties.
Based on the GPR data, a new heuristic event detection and association algorithm was developed that allows to identify and to extract relevant information from GPR data. 
It is demonstrated for synthetic and measured data that this approach provides reasonably accurate estimates for the spatial distribution of materials and their soil hydraulic material properties.

description: Introduction: The COVID-19 pandemic has deeply influenced the primary healthcare system in Portugal. Knowing that the first two years of life are a period of major development, it is necessary to comply with all the standard moments of screening, surveillance and immunization in this period. The aim of this study was to characterize health surveillance in the first two years, as well as to evaluate the fulfilment of the guideline 008/2020 release on 26th March 2020 by the Portuguese Directorate-General for Health, during the COVID-19 pandemic. Material and Methods: Cross-sectional study based on the application of an anonymous questionnaire to caretakers of children until 24 months of age through social media. The collected data refers to the period of March 2020 to March 2021. Results: This study included 452 children. The coverage of the newborn metabolic screening was 99.6%. Regarding vaccination, 81.9% of the children fulfilled the national program on time and 15.9% with delay. Around 1/3 of the children experienced delay and/or cancelation of the routine consultations. In the group of children aged between 12 to 18 months (n=150), 69.3% complied with the minimum of six consultations during the 1st year of life; and in the group aged between 18 to 24 months (n=116), 72.4% complied with the minimum of one consultation during this period. Conclusion: It is necessary to create strategies to improve compliance with the 008/2020 guideline, especially regarding immunization and consultations at the defined ages, in order to optimize children health surveillance even during pandemics.

The subjects were asked to select an object from among a group of items randomly placed on the computer screen that were visible exclusively during the visual search process. A model expressing the mean object acquisition time as a function of graphical object size and the configuration was developed and statistically validated. The model showed an influence of geometrical design characteristics of the graphical objects (icons) and their groupings (icon structures) on the observed task efficiency. The reported results can be used at those stages of a software lifecycle that concentrate on prototyping, designing, and implementing graphical solutions for the efficient graphical user-computer interface.

description: Generalizing a result (the case $k = 1$) due to M. A. Perles, we show that any polytopal upper bound sphere of odd dimension $2k + 1$ belongs to the generalized Walkup class ${\cal K}_k(2k + 1)$, i.e., all its vertex links are $k$-stacked spheres. This is surprising since the $k$-stacked spheres minimize the face-vector (among all polytopal spheres with given $f_0,..., f_{k - 1}$) while the upper bound spheres maximize the face vector (among spheres with a given $f_0$). It has been conjectured that for $d\neq 2k + 1$, all $(k + 1)$-neighborly members of the class ${\cal K}_k(d)$ are tight. The result of this paper shows that, for every $k$, the case $d = 2k +1$ is a true exception to this conjecture.

description: Accurate low-order structure factors (Fg) measured by quantitative convergent beam electron diffraction (QCBED) were used for validation of different density functional theory (DFT) approximations. 23 low-order Fg were measured by QCBED for the transition metals Cr, Fe, Co, Ni, and Cu, and the transition metal based intermetallic phases γ-TiAl, β-NiAl and γ1-FePd using a multi-beam off-zone axis (MBOZA) method and then compared with Fg calculated ab-initio by DFT using the local spin density approximation (LDA) and LDA+U, and different generalized gradient approximations (GGA) functionals. Different functionals perform very differently for different materials and crystal structures. Among the GGA functionals, PW91 and EV93 achieve the best overall agreement with the experimentally determined low-order Fg for the five metals, while PW91 performs the best for the three intermetallics. The LDA+U approach, through careful selection of U, achieves excellent matches with the experimentally measured Fg for all the metallic systems investigated in this paper. Similar to the band gap for semiconductors, it is proposed that experimentally determined low-order Fg can be used to tune the U term in LDA+U method DFT calculations for metals and intermetallics.

description: We present here a detailed pulsational study applied to low-mass He-core white dwarfs, based on full evolutionary models representative of these objects. The background stellar models on which our pulsational analysis was carried out were derived by taking into account the complete evolutionary history of the progenitor stars, with special emphasis on the diffusion processes acting during the white dwarf cooling phase. We computed nonradial $g$-modes to assess the dependence of the pulsational properties of these objects with stellar parameters such as the stellar mass and the effective temperature, and also with element diffusion processes. We also performed a g- and p-mode pulsational stability analysis on our models and found well-defined blue edges of the instability domain, where these stars should start to exhibit pulsations. We found substantial differences in the seismic properties of white dwarfs with $M_* \gtrsim 0.20 M_{\odot}$ and the extremely low-mass (ELM) white dwarfs ($M_* \lesssim 0.20 M_{\odot}$). Specifically, $g$-mode pulsation modes in ELM white dwarfs mainly probe the core regions and are not dramatically affected by mode-trapping effects by the He/H interface, whereas the opposite is true for more massive He-core white dwarfs. We found that element diffusion processes substantially affects the shape of the He/H chemical transition region, leading to non-negligible changes in the period spectrum of low-mass white dwarfs. Our stability analysis successfully predicts the pulsations of the only known variable low-mass white dwarf (SDSS J184037.78+642312.3), and also predicts both $g$- and $p$-mode pulsational instabilities in a significant number of known low-mass and ELM white dwarfs.

description: Panda-X is a liquid xenon dual-phase detector for the Dark Matter Search. The first modestly-sized module will soon be installed in the China JinPing Deep Underground Laboratory in Sichuan province, P.R. China. The cryogenics system is designed to handle much larger detectors, even the final version in the ton scale. Special attention has been paid to the reliability, serviceability, and adaptability to the requirements of a growing experiment. The system is cooled by a single Iwatani PC150 Pulse Tube Refrigerator. After subtracting all thermal losses, the remaining cooling power is still 82W. The fill speed was 9 SLPM, but could be boosted by LN2 assisted cooling to 40 SLPM. For the continuous recirculation and purification through a hot getter, a heat exchanger was employed to reduce the required cooling power. The recirculation speed is limited to 35 SLPM by the gas pump. At this speed, recirculation only adds 18.5 W to the heat load of the system, corresponding to a 95.2 % efficiency of the heat exchanger.

description: Pattern tree are based on integrated rules which are equal to a combination of some points connected to each other in a hierarchical structure, called Enquiry Hierarchical (EH). The main operation in pattern enquiry seeking is to locate the steps that match the given EH in the dataset. A point of algorithms has offered for EH matching; but the majority of this algorithms seeks all of the enquiry steps to access all EHs in the dataset. A few algorithms such as seek only steps that satisfy end points of EH. All of above algorithms are trying to locate a way just for investigating direct testing of steps and to locate the answer of enquiry, directly via these points. In this paper, we describe a novel algorithm to locate the answer of enquiry without access to real point of the dataset blindly. In this algorithm, first, the enquiry will be executed on enquiry schema and this leads to a schema. Using this plan, it will be clear how to seek end steps and how to achieve enquiry dataset, before seeking of the dataset steps. Therefore, none of dataset steps will be seek blindly.

title: Probabilistic photometric redshift estimation in massive digital sky surveys via machine learning
Creators: name: D'Isanto, Antonio
Publisher: name: Heidelberg University Library
Year: 2019

description: The problem of photometric redshift estimation is a major subject in astronomy, since the need of estimating distances for a huge number of sources, as required by the data deluge of the recent years. The ability to estimate redshifts through spectroscopy does not scale with this avalanche of data. Photometric redshifts provide the required redshift estimates at the cost of some precision. The success of several forthcoming missions is highly dependent on the availability of photometric redshifts.
The purpose of this thesis is to provide innovative methods for photometric redshift estimation. Two models are proposed. The first is fully-automatized, based on the combination of a convolutional neural network with a mixture density network, to predict probabilistic multimodal redshifts directly from images. The second model is features-based, performing a massive combination of photometric parameters to apply a forward selection in a huge feature space. The proposed models perform very efficiently compared to some of the most common models used in the literature. An important part of the work is dedicated to the correct estimation of the errors and prediction quality.
The proposed models are very general and can be applied to different topics in astronomy and beyond.

description: The de-excitation of compound nuclei has been successfully described for several decades by means of statistical models. However, accurate predictions require some fine-tuning of the model parameters. This task can be simplified by studying several entrance channels, which populate different regions of the parameter space of the compound nucleus. Fusion reactions play an important role in this strategy because they minimise the uncertainty on the entrance channel by fixing mass, charge and excitation energy of the compound nucleus. If incomplete fusion is negligible, the only uncertainty on the compound nucleus comes from the spin distribution. However, some de-excitation channels, such as fission, are quite sensitive to spin. Other entrance channels can then be used to discriminate between equivalent parameter sets. The focus of this work is on fission and intermediate-mass-fragment emission cross sections of compound nuclei with 70<=A<=240. The statistical de-excitation model is GEMINI++. The choice of the observables is natural in the framework of GEMINI++, which describes fragment emission using a fission-like formalism. Equivalent parameter sets for fusion reactions can be resolved using the spallation entrance channel. This promising strategy can lead to the identification of a minimal set of physical ingredients necessary for a unified quantitative description of nuclear de-excitation.
