description: Context: A long-term goal of exoplanet research is to characterize the atmospheres of a sizable sample of temperate terrestrial exoplanets. Such studies will build our knowledge about the diversity of terrestrial worlds and enable the discovery of habitable or even inhabited worlds. To achieve this goal, missions capable of measuring the spectra of temperate terrestrial exoplanets have been proposed (LUVOIR/HabEx - optical & near-infrared; Large Interferometer For Exoplanets (LIFE)[1] - mid-infrared (MIR)). The MIR thermal emission measured by LIFE provides exclusive probes to important molecules (e.g. the potential bioindicators CH4, O3). Further, the MIR observations can provide constraints on a planet’s pressure-temperature (PT) profile, radius, and surface conditions. Methods & Results: We present results from our recent atmospheric retrieval studies. We investigated a cloud-free Earth- [2] and, to our knowledge for the first time, a cloudy Venus-twin [3] exoplanet around a sun-like star at 10 pc. We simulate the MIR planet emission spectra with petitRADTRANS (1D radiative transfer model) [4] and use LIFESim [5], to estimate the wavelength-dependent noise expected for exoplanet observations with LIFE. Our retrieval suite uses the atmospheric model petitRADTRANS and the MultiNest algorithm [6] for parameter estimation. We retrieve the planetary mass and radius, the PT profile, the surface pressure, the molecular abundances and the cloud parameters. By considering input spectra of different wavelength ranges, resolutions (R), and noise levels (S/N), we aim to determine the requirements to: discriminate Earth- from Venus-like MIR spectra, characterize the structure and composition of atmospheres, detect potential biomarkers in Earth-twin, infer the presence of clouds in atmospheres, constrain cloud structure and composition in a Venus-twin. We also discuss challenges in the analysis of MIR exoplanet spectra from LIFE via atmospheric retrievals and how differences in the quality of the spectra affect them. Conclusion: With these studies and an additional retrieval study for Earth at different times [7], we find first constraints for the instrument requirements for the LIFE interferometer and identify important limitations and challenges of MIR atmospheric retrieval studies for exoplanets.

title: Das Wiener Zwangsarbeitshaus 1804 bis 1838
Creators: name: Haller, Philipp
Year: 2022

description: Diese Masterarbeit beschäftigt sich mit dem Wiener Zwangsarbeitshaus auf der Laimgrube von seinem Gründungsjahr 1804 bis in das Jahr 1838. Grundlage der Arbeit war eine intensive Quellenarbeit und die für den Untersuchungszeitraum notwendige Transkription und Analyse des sogenannten Normalienbuches, eine einzigartige Quelle, die einen detaillierten Blick in Organisation und Alltag dieser Anstalt ermöglicht. Das Normalienbuch entstand aus Aktenabschriften der ausführenden Hofkommission. Mit den Methoden der Strukturierung von „coerced labour“ nach Marcel van der Linden wurde das Material strukturiert und analysiert. Dabei wurde Fragen nach den Modalitäten der Zwangsarbeit nachgegangen. Ebenso wurden die Lebensverhältnisse der InsassInnen und deren sozialer Hintergrund untersucht. Dadurch konnten Erkenntnisse über Formen der Arbeit, der Belohnung, der Bestrafung sowie der Verpflegung gewonnen werden. Auch das Anstaltspersonal wurde untersucht, sowie die Hofkommission, welche die Anstalt gründete. Die Arbeit leistet einen detaillierten Einblick in die Österreichischen Zwangsarbeitsanstalten, welche erst im 20. Jahrhundert endgültig abgeschafft wurden. Die Geschichte dieser Anstalten und das Leben ihrer InsassInnen wurde für die zweite Hälfte des 19. Jahrhunderts und darüber hinaus teilweise erforscht. Über die Gründung der Anstalt und ihre Genese in der ersten Hälfte des 19. Jahrhunderts existierte bisher kaum detaillierte Forschung. Das verwendete Quellenmaterial wurde nun erstmals zur Gänze für die Jahre 1804 bis 1838 analysiert. Die Methodik kann in Zukunft auch auf weiteres, bisher unbearbeitetes, Quellenmaterial angewandt werden.
description: This thesis investigates the history of the forced labour facility in Vienna in the years from 1804 until 1838. The analysis is based on an extensive study of primary sources. The so called “Normalienbuch” has been transcripted and analysed for the period in question. This source – produced by the bureaucratic entity behind the forced labour facility – is a unique document, which allows a detailed observation of the daily routines and the organization of the “Zwangsarbeitshaus”. With a theoretic concept, mainly based on the work of Marcel van der Linden, it was possible to analyse the modalities of forced labour within this institution. In this way insights were gathered on the type of work, on incentives and punishment, on the live and social background of inmates, guards and officials. The thesis offers new findings on the origin and genesis of Austrian forced labour facilities which, until now, have mostly been studied for the second half of the 19th century and beyond. For the first time ever, the available sources have been studied entirely, for the years between 1804 and 1838. In the future the methodology can be applied to further, hitherto unseen, source material.

description: Multiferroic materials, in which ferroelectric and magnetic ordering coexist, are of fundamental interest for the development of novel memory devices that allow for electrical writing and non-destructive magnetic readout operation. The great challenge is to create room temperature multiferroic materials with strongly coupled ferroelectric and ferromagnetic (or ferrimagnetic) orderings. BiFeO3 has been the most heavily investigated single-phase multiferroic to date due to the coexistence of its magnetic order and ferroelectric order at room temperature. However, there is no net magnetic moment in the cycloidal (antiferromagnetic-like) magnetic state of bulk BiFeO3, which severely limits its realistic applications in electric field controlled spintronic devices. Here, we predict that double perovskite Zn2FeOsO6 is a new multiferroic with properties superior to BiFeO3. First, there are strong ferroelectricity and strong ferrimagnetism at room temperature in Zn2FeOsO6. Second, the easy-plane of the spontaneous magnetization can be switched by an external electric field, evidencing the strong magnetoelectric coupling existing in this system. Our results suggest that ferrimagnetic 3d-5d double perovskite may therefore be used to achieve voltage control of magnetism in future spintronic devices.

description: Bell experiments can be used to generate private random numbers. An ideal Bell experiment would involve measuring a state of two maximally entangled qubits, but in practice any state produced is subject to noise. Here we consider how the techniques presented in arXiv:1309.3894 and arXiv:1309.3930, i.e. using an optimized Bell inequality, and taking advantage of the fact that the device provider is not our adversary, can be used to improve the rate of randomness generation in Bell-like tests performed on singlet states subject to either white or dephasing noise.

description: Large-area sky surveys show that massive galaxies undergo at least one major merger in a Hubble time. Ongoing pulsar timing array (PTA) experiments are aimed at measuring the gravitational wave (GW) emission from binary supermassive black holes (SMBHs) at the centres of galaxy merger remnants. In this paper, using the latest observational estimates for a range of galaxy properties and scaling relations, we predict the amplitude of the GW background generated by the binary SMBH population. We also predict the numbers of individual binary SMBH GW sources. We predict the characteristic strain amplitude of the GW background to lie in the range $5.1\times10^{-16}

description: Use of antiretroviral treatment for HIV-1 infection has decreased AIDS-related morbidity and mortality and prevents sexual transmission of HIV-1. However, the best time to initiate antiretroviral treatment to reduce progression of HIV-1 infection or non-AIDS clinical events is unknown. We reported previously that early antiretroviral treatment reduced HIV-1 transmission by 96%. We aimed to compare the effects of early and delayed initiation of antiretroviral treatment on clinical outcomes.

description: In this paper, two new series for the logarithm of the $Γ$-function are presented and studied. Their polygamma analogs are also obtained and discussed. These series involve the Stirling numbers of the first kind and have the property to contain only rational coefficients for certain arguments related to $π^{-1}$. In particular, for any value of the form $\lnΓ(\frac{1}{2}n\pmαπ^{-1})$ and $Ψ_k(\frac{1}{2}n\pmαπ^{-1})$, where $Ψ_k$ stands for the $k$th polygamma function, $α$ is positive rational greater than $\frac{1}{6}π$, $n$ is integer and $k$ is non-negative integer, these series have rational terms only. In the specified zones of convergence, derived series converge uniformly at the same rate as $\sum(n\ln^m\!n)^{-2}$, where $m=1, 2, 3,\ldots$\,, depending on the order of the polygamma function. Explicit expansions into the series with rational coefficients are given for the most attracting values, such as $\lnΓ(π^{-1})$, $\lnΓ(2π^{-1})$, $\lnΓ(\tfrac{1}{2}+π^{-1})$, $Ψ(π^{-1})$, $Ψ(\tfrac{1}{2}+π^{-1})$ and $Ψ_k(π^{-1})$. Besides, in this article, the reader will also find a number of other series involving Stirling numbers, Gregory's coefficients (logarithmic numbers, also known as Bernoulli numbers of the second kind), Cauchy numbers and generalized Bernoulli numbers. Finally, several estimations and full asymptotics for Gregory's coefficients, for Cauchy numbers, for certain generalized Bernoulli numbers and for certain sums with the Stirling numbers are obtained. In particular, these include sharp bounds for Gregory's coefficients and for the Cauchy numbers of the second kind.

description: Clear cell renal cell carcinoma (ccRCC) displays a variety of clinical behaviors. However, the molecular genetic events driving these behaviors are unknown. We discovered that BAP1 is mutated in approximately 15% of ccRCC and that BAP1 and PBRM1 mutations are largely mutually exclusive. The aim of this study was to investigate the clinicopathological significance of these molecular subtypes and to determine whether patients with BAP1-mutant and PBRM1-mutant tumors had different overall survival.
Rare Flavor Processes in Maximally Natural Supersymmetry

description: We study CP-conserving rare flavor violating processes in the recently proposed theory of Maximally Natural Supersymmetry (MNSUSY). MNSUSY is an unusual supersymmetric (SUSY) extension of the Standard Model (SM) which, remarkably, is un-tuned at present LHC limits. It employs Scherk-Schwarz breaking of SUSY by boundary conditions upon compactifying an underlying 5-dimensional (5D) theory down to 4D, and is not well-described by softly-broken $\mathcal{N}=1$ SUSY, with much different phenomenology than the Minimal Supersymmetric Standard Model (MSSM) and its variants. The usual CP-conserving SUSY-flavor problem is automatically solved in MNSUSY due to a residual almost exact $U(1)_R$ symmetry, naturally heavy and highly degenerate 1st- and 2nd-generation sfermions, and heavy gauginos and Higgsinos. Depending on the exact implementation of MNSUSY there exist important new sources of flavor violation involving gauge boson Kaluza-Klein (KK) excitations. The spatial localization properties of the matter multiplets, in particular the brane localization of the 3rd generation states, imply KK-parity is broken and {\it tree-level} contributions to flavor changing neutral currents are present in general. Nevertheless, we show that simple variants of the basic MNSUSY model are safe from present flavor constraints arising from kaon and $B$-meson oscillations, the rare decays $B_{s,d} \to μ^+ μ^-$, $μ\to {\bar e}ee$ and $μ$-$e$ conversion in nuclei. We also briefly discuss some special features of the radiative decays $μ\to e γ$ and ${\bar B}\to X_s γ$. Future experiments, especially those concerned with lepton flavor violation, should see deviations from SM predictions unless one of the MNSUSY variants with enhanced flavor symmetries is realized.

We compute the fixed time Dirac bracket algebra that acts on two different phase spaces. Both of these spaces contain black holes as zero modes. The result for one of these phase spaces is explicitly shown to be isomorphic to $W^{(2)}_3\times W^{(2)}_3$ in first order perturbations.

The inner disc tracers of the physics and chemistry of disc evolution.
Creators: name: Booth, Richard
Publisher: name: Zenodo
Year: 2018

description: Protoplantetary discs play an essential role in our understanding of planet formation, with the chemical competition of planets offering an exciting way to probe conditions where they form. One challenge today in assessing the mass and bulk composition of protoplanetary discs is that many key species are hidden from view, being frozen out in the mid-plane throughout large portions of protoplanetary discs. Conversely, in inner regions of discs many species are directly observable in atomic, gaseous form, thus avoiding these difficulties. Since the composition of the inner disc is connected to the outer disc through the radial transport of gas and dust, it provides a way to constrain both the chemical and transport processes acting in protoplanetary discs. I will present the results of a new investigation into the interplay between chemical evolution and radial transport through accretion and radial drift, discussing how the composition of the inner disc changes in response to these processes. I will discuss these results in the context of inner disc observations and what they mean for the growth and transport of dust, and implications for the chemical evolution of the outer disc.
Social Diffusion and Global Drift on Networks

description: We study a mathematical model of social diffusion on a symmetric weighted network where individual nodes' states gradually assimilate to local social norms made by their neighbors' average states. Unlike physical diffusion, this process is not state conservational and thus the global state of the network (i.e., sum of node states) will drift. The asymptotic average node state will be the average of initial node states weighted by their strengths. Here we show that, while the global state is not conserved in this process, the inner product of strength and state vectors is conserved instead, and perfect positive correlation between node states and local averages of their self/neighbor strength ratios always results in upward (or at least neutral) global drift. We also show that the strength assortativity negatively affects the speed of homogenization. Based on these findings, we propose an adaptive link weight adjustment method to achieve the highest upward global drift by increasing the strength-state correlation. The effectiveness of the method was confirmed through numerical simulations and implications for real-world social applications are discussed.

description: ABSTRACT
 Purpose – The purpose of this study is to measure and compare the brand value and financial performances of capital market intermediary institutions that whose shares are traded on the Borsa Istanbul.
 Design/methodology/approach – The data used in the study is available on the Capital Markets Associationof Turkey (www.tspb.org.tr) and the Public Disclosure Platform (www.kap.org.tr). The Hirose method, which is the most preferred method in the literature for calculating company brand values, and the Gray Relational Analysis (GHI) method, a multi-criteria decision-making method, were used in measuring financial performance. The impact of the financial ratios of the intermediary institutions on the brand values calculated using the Hirose method was ascertained by the regression analysis. The relationships between the brand values calculated using the Hirose method and the GIA financial performance ranking results were analyzed comparatively.
 Findings – The study has determined that there is a negative correlation between the borrowing rate and brand value. As the net working capital ratio increases, brand value decreases. In this respect, there is a negative correlation between net working capital and brand value. There were negative correlations between the liquidity ratios and brand value. Based on the period data from 2016 to 2020, 29.5 percent of the brand value can be explained with the market value. A meaningful relationship (negative) between the GIA financial performance ranking results and brand values was determined within the context of 2016 data only. GLBMD was found to be the best performing brokerage house for three consecutive years. 2016 GEDIK is the brokerage house with the best performance in the GIA performance ranking results, and the brokerage house with the lowest performance is set as INFO.
 Discussion – The number of studies on the brand values and financial performances of intermediary institutions that provide brokerage services in capital markets and whose shares are traded on Borsa Istanbul is limited. Analyzes have not identified a meaningful relationship between the financial performance rankings and the brand values, excluding 2016. There is also no meaningful relationship between brand values and market values. The results of the study revealed that the brand values of intermediary institutions whose shares are traded at Borsa Istanbul fell short in announcing financial performance and market values. The study results are believed to guide investment decisions of investors interested in investing in the shares of related institutions.
Constraining the density slope of nuclear symmetry energy at subsaturation densities using electric dipole polarizability in $^{208}$Pb

description: Nuclear structure observables usually most effectively probe the properties of nuclear matter at subsaturation densities rather than at saturation density. We demonstrate that the electric dipole polarizibility $α_ {\text{D}}$ in $^{208}$Pb is sensitive to both the magnitude $E_{\text{sym}}(ρ_{\text{c}})$ and density slope $L(ρ_{\text{c}})$ of the symmetry energy at a subsaturation cross density $ρ_{\text{c}} = 0.11$ fm$^{-3}$. Using the experimental data of $α_ {\text{D}}$ in $^{208}$Pb from RCNP and the recent accurate constraint of $E_{\text{sym}}(ρ_{\text{c}})$ from the binding energy difference of heavy isotope pairs, we extract a value of $L(ρ_{\text{c}}) = 47.3 \pm 7.8$ MeV. The implication of the present constraint of $L(ρ_{\text{c}})$ to the symmetry energy at saturation density, the neutron skin thickness of $^{208}$Pb and the core-crust transition density in neutron stars is discussed.

description: How do the smallest scales (star-disk interaction at 0.01-0.1 au) connect with the larger ones (disk structure at 1-10 AU) is one of the major issues to be addressed in the framework of disk evolution and planet formation. Does the inner disk edge "feel" what is occurring at larger scales? Conversely, does the complex star-disk interaction process impact on the larger disk structure? How do forming planets modify (govern?) the connection between inner and outer disk scales? I here provide a few graphic slides to illustrate the relevant scales and associated physical processes.

Planetesimal formation in the inner region of the protoplanetary disk
Creators: name: Drazkowska, Joanna
Publisher: name: Zenodo
Year: 2018

description: Formation of the first gravitationally bound building blocks of planets, called planetesimals, is one of the most prominent challenges faced by our understanding of planet formation. As the dust growth is limited by fragmentation and radial drift, the direct growth to planetesimal sizes seems unlikely. However, the same processes drive the global redistribution of solids and may lead to a pile-up of pebbles that triggers planetesimal formation. I will present the recent models which combine dust growth, radial drift, and planetesimal formation via streaming instability. These results consistently show that the first planetesimals are more likely to be formed in the inner regions of the protoplanetary disk, where the dust growth timescale is shorter than the radial drift timescale.

description: A vast range of disorders—from indolent to fast-growing lesions—are labelled as cancer. Therefore, we believe that several changes should be made to the approach to cancer screening and care, such as use of new terminology for indolent and precancerous disorders. We propose the term indolent lesion of epithelial origin, or IDLE, for those lesions (currently labelled as cancers) and their precursors that are unlikely to cause harm if they are left untreated. Furthermore, precursors of cancer or high-risk disorders should not have the term cancer in them. The rationale for this change in approach is that indolent lesions with low malignant potential are common, and screening brings indolent lesions and their precursors to clinical attention, which leads to overdiagnosis and, if unrecognised, possible overtreatment. To minimise that potential, new strategies should be adopted to better define and manage IDLEs. Screening guidelines should be revised to lower the chance of detection of minimal-risk IDLEs and inconsequential cancers with the same energy traditionally used to increase the sensitivity of screening tests. Changing the terminology for some of the lesions currently referred to as cancer will allow physicians to shift medicolegal notions and perceived risk to reflect the evolving understanding of biology, be more judicious about when a biopsy should be done, and organise studies and registries that offer observation or less invasive approaches for indolent disease. Emphasis on avoidance of harm while assuring benefit will improve screening and treatment of patients and will be equally effective in the prevention of death from cancer.

We confirm the value of the nuclear critical charge $Z_{cr}$ recently calculated in Estienne et al. {\em Phys. Rev.

We show that the ground state energy for H$^-$ is accurate to 14 decimals on the lattice $50 \times 50 \times 40$ in comparison with the highly accurate result by Nakashima-Nakatsuji, {\it J. Chem. Phys. \bf 127}, 224104 (2007).

Publisher: name: Zenodo
Year: 2018

description: The atomic helium line at 10830 Angstroms readily shows deep absorption features on both the red and blue sides of line center. Due to helium's high excitation potential, these absorption features probe accretion and outflow, respectively, in the innermost 0.1 AU of accreting star-disk systems. I will present spectra of this transition in young stellar objects with a range of inclination angles and accretion rates, including stars that are undergoing luminosity outbursts. The profiles will be interpreted in light of recent high-resolution images of these systems that probe somewhat larger scales in the inner disk.

description: We perform a thorough study of greybody factors for minimally-coupled scalar fields propagating on the background of rotating black holes in higher (odd) dimensions with all angular momenta set equal. For this special case, the solution enjoys an enhanced symmetry, which translates into the advantageous feature of being cohomogeneity-1, i.e., these backgrounds depend on a single radial coordinate. Our analysis contemplates three distinct situations, with the cosmological constant being zero, positive or negative. Using the technique of matched asymptotic expansions we compute analytically the greybody factors in the low-frequency regime, restricting to s-wave scattering. Our formulas generalize those obtained previously in the literature for the static and spherically symmetric case, with corrections arising from the change in the horizon area due to rotation. It is also proven that, for this family of black holes, the horizon area is a decreasing function of the spin parameter, without regard of dimensionality and of cosmological constant. Through an improvement on a calculation specific to the class of small black holes in anti-de Sitter and not restricted to the usual low-frequency regime, we uncover a rich structure of the greybody spectrum, more complex than previously reported but also enjoying a certain degree of universality. We complement our low-frequency analytic results with numerical computations valid over a wide range of frequencies and extend them to higher angular momentum quantum numbers, $\ell>0$. This allows us to probe the superradiant regime that is observed for corotating wavefunctions. We point out that the maximum amplification factor for intermediate-size black holes in anti-de Sitter can be surprisingly large.

The dimmings of RW Aur. Is the dust accretion preceding an outburst?
Creators: name: Gárate, Matías
Publisher: name: Zenodo
Year: 2018

description: In the recent years, RW Aur A has presented multiple dimming events that last for a few months. The origin of this phenomena remains yet to be uncovered, although several explanations are available. Using numerical simulations, we study how the dust accumulates in a dead zone located at the inner regions of the protoplanetary disk. Should the dead zone be re-activated, all the accumulated material will be flushed towards the star, in particular, the dust excess will travel faster than the gas, potentially blocking the starlight and causing the dimming events. Afterwards the accretion of gas will follow, causing an outburst.

description: In 2007 Rindler and Ishak showed that, contrary to previous claims, the value of the cosmological constant does have an effect on light deflection by a gravitating object in an expanding universe, modeled by a Schwarzschild-de~Sitter spacetime. In this paper we consider light bending in the more general situation of a gravitating object in a cosmological background with varying expansion rate $H(t)$. We calculate numerically the null geodesics representing light rays deflected by a black hole in an accelerating Friedmann-Lemaître-Robertson-Walker universe, modeled by a McVittie metric. Keeping the values of the distances from the observer to the lensing object and to the source fixed, we plot the dependence of the bending angle measured by two different sets of observers in this spacetime on the rate of change of $H(t)$.

description: Treatment of breast cancer with aromatase inhibitors is associated with damage to bones. NCIC CTG MA.27 was an open-label, phase 3, randomised controlled trial in which women with breast cancer were assigned to one of two adjuvant oral aromatase inhibitors—exemestane or anastrozole. We postulated that exemestane—a mildly androgenic steroid—might have a less detrimental effect on bone than non-steroidal anastrozole. In this companion study to MA.27, we compared changes in bone mineral density (BMD) in the lumbar spine and total hip between patients treated with exemestane and patients treated with anastrozole.
The outer disk knows about the inner disk
Creators: name: Garufi, Antonio
Publisher: name: Zenodo
Year: 2018

description: The morphology and composition of star and inner disk also have an impact on the disk structure at larger radii. In fact, the shadows, spirals, rings that have been recurrently imaged at >5 au can be traced back to stellar mass and metallicity as well as to the presence of a misaligned inner belt within a disk cavity. We show the trends found over a large sample of objects and discuss the possibility that the inner disk may also regulate the planet formation by affecting the outer disk properties.
title: The effect of organizational culture on female leadership in Austria
Creators: name: Paulmichl, Samira

description: Im Hinblick auf die Besetzung von Führungspositionen in Unternehmen sind Frauen nach wie vor weltweit, wie auch in Österreich, unterrepräsentiert. Das Ziel der europäischen Union und auch der österreichischen Demokratie ist es, ein ausgeglichenes Verhältnis von Frauen in Führungs- und Entscheidungspositionen zu schaffen. Neben dem politischen Aspekt beleuchtet diese Arbeit auch den betriebswirtschaftlichen Aspekt und zeigt auf, wie Frauen in Führungspositionen den Unternehmenserfolg positiv beeinflussen können. Das Ziel dieser Arbeit ist es herauszufinden, ob bzw. wie Organisationskultur den Anteil von Frauen in Führungspositionen sowie deren Karrierefortschritt beeinflusst. Die Untersuchungsobjekte dieser Arbeit sind die österreichischen Unternehmen des Prime Market der Wiener Börse. Um Organisationskultur zu messen, wurde ein Fragebogen erstellt und an Mitarbeiter dieser Unternehmer versendet. Die durchgeführte Regressionsanalyse zeigt, dass nur eines der vorab acht definierten Elemente von Organisationskultur einen signifikanten Einfluss auf den Anteil von Frauen in Führungspositionen hat, nämlich, dass Männer und Frauen in Meetings gleichermaßen gehört werden. Zusätzlich zeigt die durchgeführte Korrelationsanalyse, dass eine Beziehung zwischen der Organisationskultur und dem Karrierefortschritt vorhanden ist.
description: With regard to leadership positions in companies, women are still underrepresented worldwide, as in Austria. The goal of the European Union and of the Austrian democracy is to create a balanced of women in leadership and decision-making positions. In addition to the political aspect, this work also elaborates the business management aspect and shows how women in leadership positions can have a positive influence on a company's success. The aim of this work is to find out whether and how organizational culture influences the share of women in leadership positions and their career advancement. The objects of investigation of this research are the Austrian companies on the prime market of the Vienna Stock Exchange. In order to assess organizational culture, a survey was created and sent to employees of these companies. The conducted regression analysis revealed that only one of the eight predefined elements of organizational culture has a significant influence on the share of women in leadership positions, namely that men and women are heard equally in meetings. In addition, the correlation analysis reveals that there is a relationship between organizational culture and career advancement.
title: Sialic acids as biomarkers for cardiovascular disease
Creators: name: Cheeseman, Jack
Publisher: name: University of Reading

description: Sialic acids are a family of over 50 derivatives of neuraminic acid that are widely available in Nature and that play many biological roles in health and disease. They are generally located at the terminus of glycans, which in turn form part of glycoproteins and glycolipids. N-Acetyl neuraminic acid (Neu5Ac), the most abundant sialic acid, has been hypothesised to be a biomarker for various diseases including cardiovascular disease (CVD). The presence of many diseases, including CVD can be linked to an increase in plasma and serum concentration of Neu5Ac in disease patients versus healthy controls. Increased Neu5Ac concentrations in plasma have also been linked to increased risk of CVD mortality. These studies have been limited in scope, studying only one derivative of sialic acid and only in plasma and serum. Multiple isomers of acetylated sialic acid exist, challenges have been encountered in synthesising these compounds however, which has hampered impact in this area. Given that Neu5Ac is associated with multiple diseases we need more precise biomarkers for diseases such as CVD. Therefore, the research described here aimed to investigate acetylated sialic acid derivatives as biomarkers for CVD and CVD mortality risk, not only in plasma and serum, but also in urine and saliva. Overall, the work carried out in this thesis details the utility of synthetic sialic acid derivatives as quantitative standards for the analysis of plasma, serum, urine, and saliva. The biomarker potential of Neu5Ac and Neu5,9Ac2 for CVD risk and the presence of advanced CVD was also evaluated.
Current status of the observational search for close-in planets
Creators: name: Haywood, Raphaëlle
Publisher: name: Zenodo
Year: 2018

description: I will give an overview of the current state of detection and characterisation of the general properties (radius, mass, orbital period) of close-in exoplanets. This talk will mainly focus on the small-sized (super-Earth to Neptune-sized) planets discovered and characterised through transit and radial-velocity monitoring. I will review recent observational evidence for distinct populations of planets, as well as observed trends in planet and host star properties. Finally, this talk will address some of the challenges that we currently face, notably for ground-based, resource-intensive radial-velocity follow-up of transiting planet candidates. These challenges include optimising observational sampling, accounting for stellar activity signals and correcting for observational biases.

description: Carbonaceous chondrites (CCs) can be considered cosmic aggregates containing protoplanetary disk components. Modern
 analytical techniques allow us to identify CCs unaffected by thermal or aqueous alteration processes, having a pristine nature. Such a highly unequilibrated meteorites allow us to get clues on the early Solar System (ESS), as their components are ancient materials
 retentive of chemical clues on their formation. The information they contain is valuable to be applied to better understand protoplanetary disks.
A Unitary Model of The Black Hole Evaporation

description: A unitary effective field model of the black hole evaporation is proposed to satisfy almost the four postulates of the black hole complementarity (BHC). In this model, we enlarge a black hole-scalar field system by adding an extra radiation detector that couples with the scalar field. After performing a partial trace over the scalar field space, we obtain an effective entanglement between the black hole and the detector (or radiation in it). As the whole system evolves, the S-matrix formula can be constructed formally step by step. Without local quantum measurements, the paradoxes of the information loss and AMPS's firewall can be resolved. However, the information can be lost due to quantum decoherence, as long as some local measurement has been performed on the detector to acquire the information of the radiation in it. But unlike Hawking's completely thermal spectrum, some residual correlations can be found in the radiations. All these considerations can be simplified in a qubit model that provides a \emph{modified quantum teleportation} to transfer the information via an EPR pairs.

The impact of magnetic fields on star-disk interaction and planet formation
Creators: name: Hussain, Gaitee
Publisher: name: Zenodo
Year: 2018

description: In this presentation we review the current understanding of stellar magnetic fields in T Tauri stars (including intermediate mass T Tauri stars [>1.3 Msun]), and we describe their apparent evolution as they evolve along their PMS tracks. Multi-wavelength observations of T Tauris allow us to probe magnetospheric accretion in more detail. The evolution in X-ray properties between the Hayashi and Henyey tracks appears to mirror that seen in magnetic field maps of our (relatively small) sample of T Tauri stars. A larger sample is needed to fully explore the range of PMS magnetic fields and their evolution -- a new generation of infrared spectro-polarimeters is under construction that will enable us to do exactly that.
Formation of close-in super-Earths: dust enrichment of the inner disk due to the MRI
Creators: name: Jankovic, Marija
Publisher: name: Zenodo
Year: 2018

description: Do the ubiquitous short-period super-Earths/mini-Neptunes form in situ, in the inner protoplanetary disk? If so, the key step to planet formation is dust enrichment of the inner disk. In the outer disk the dust particles are expected to quickly grow by coagulation and drift inwards due to gas drag. The inner disk structure, governed by viscous accretion due to the magneto-rotational instability (MRI), features a local gas pressure maximum that could potentially trap the drifting dust particles. We consider evolution of dust, including growth, radial drift and fragmentation, in a steady-state gas disk, with the inner disk gas structure self-consistently determined from MRI criteria (Mohanty et al. 2017). We find that in the inner disk the dust particle size is limited by fragmentation due to relative turbulent velocities. The particles remain too small to feel significant gas drag and therefore do not accumulate at the local gas pressure maximum. However, as a decrease in particle size also implies less radial drift for the particles from the outer disk, this ultimately leads to dust enhancement throughout the inner disk, interior to the pressure maximum.
