title: Datenschutz bei der Verwendung von maschineller Übersetzung: der Umgang mit sensiblen Textinhalten in der translatorischen Praxis
Creators: name: Puchegger, Anita
Year: 2023

description: Mit den technologischen Fortschritten in allen Bereichen des Lebens fand die Technologie in Form von maschinellen Übersetzungs-Tools (MÜ-Tools) auch Einzug in die Übersetzungsbranche. Diese Tools entwickeln sich ständig weiter und werden zunehmend besser, aber mit diesen Entwicklungen entstehen auch Gefahren und Risiken. Um diese Tools weiterentwickeln und verbessern zu können, wird eine Unmenge an Daten benötigt, die vor allem durch die kostenlos angebotenen Versionen dieser MÜ-Tools gesammelt werden. Somit stellte sich im Rahmen der vorliegenden Masterarbeit die Frage, wie aktuell in der Branche mit sensiblen Inhalten (personenbezogenen Daten) bei der Verwendung von maschineller Übersetzung umgegangen wird. Zur Beantwortung dieser Frage wurden Expert:inneninterviews mit Übersetzer:innen und Projektmanager:innen geführt, die anschließend transkribiert und ausgewertet wurden. Aus den Ergebnissen der Interviews kann geschlossen werden, dass in der Branche für den gesetzlich notwendigen Datenschutz gesorgt wird, jedoch sensible Inhalte bei MÜ-Aufträgen (noch) nicht gesondert behandelt werden.
description: Considering the technological advancements in all aspects of our life, it is no wonder that technology also found its way into the translation industry as machine translation (MT). These tools are improving rapidly, but with these improvements also come great risks. Because in order to further develop these tools, large amounts of data are needed. Therefore, this Master’s thesis tries to get a glimpse into how sensitive data (personal data) is treated in the translation industry when MT is used to carry out a translation task. To answer this question, eight interviews with experts in the field were conducted and subsequently transcribed and analyzed. The findings of this analysis show that legally required data protection is ensured by the industry, but sensitive data is not (yet) being treated differently when translations are performed with MT.

description: Standard galaxy formation models predict that large-scale double-lobed radio sources, known as DRAGNs, will always be hosted by elliptical galaxies. In spite of this, in recent years a small number of spiral galaxies have also been found to host such sources. These so-called spiral DRAGNs are still extremely rare, with only $\sim 5$ cases being widely accepted. Here we report on the serendipitous discovery of a new spiral DRAGN in data from the Giant Metrewave Radio Telescope (GMRT) at 322 MHz. The host galaxy, MCG+07-47-10, is a face-on late-type Sbc galaxy with distinctive spiral arms and prominent bulge suggesting a high black hole mass. Using WISE infra-red and GALEX UV data we show that this galaxy has a star formation rate of 0.16-0.75 M$_{\odot}$yr$^{-1}$, and that the radio luminosity is dominated by star-formation. We demonstrate that this spiral DRAGN has similar environmental properties to others of this class, but has a comparatively low radio luminosity of $L_{\rm 1.4GHz}$ = 1.12$\times$10$^{22}$ W Hz$^{-1}$, two orders of magnitude smaller than other known spiral DRAGNs. We suggest that this may indicate the existence of a previously unknown low-luminosity population of spiral DRAGNS.

description: Nanofluids; dispersions of nanometer-sized particles in a liquid medium; have been proposed for a wide variety of thermal management applications. It is known that a solid-like nanolayer of liquid of typical thickness 0.5-1 nm surrounding the colloidal nanoparticles can act as a thermal bridge between the nanoparticle and the bulk liquid. Yet, its effect on the nanofluid viscosity has not been elucidated so far. In this article, we compute the local viscosity of the nanolayer using equilibrium molecular dynamics based on the Green-Kubo formula. We first assess the validity of the method to predict the viscosity locally. We apply this methodology to the calculation of the local viscosity in the immediate vicinity of a metallic nanoparticle for a wide range of solid-liquid interaction strength, where a nanolayer of thickness 1 nm is observed as a result of the interaction with the nanoparticle. The viscosity of the nanolayer, which is found to be higher than its corresponding bulk value, is directly dependent on the solid-liquid interaction strength. We discuss the origin of this viscosity enhancement and show that the liquid density increment alone cannot explain the values of the viscosity observed. Rather, we suggest that the solid-like structure of the distribution of the liquid atoms in the vicinity of the nanoparticle contributes to the nanolayer viscosity enhancement. Finally, we observe a failure of the Stokes-Einstein relation between viscosity and diffusion close to the wall, depending on the liquid-solid interaction strength, which we rationalize in terms of hydrodynamic slip.
“O that I did truly love! For by love only my soul shall become capable of understanding truth”: Dame Gertrude More’s The Spiritual Exercises (1658) from a feminist perspective on religious women’s agency and on mysticism and gender

description: English Catholic nuns from the early-modern period were marginalised voices for several reasons: firstly, they were women, in a historical context where their voices were usually not expressed and not heard; secondly, they were Catholic under the penal laws; finally, they were exiled on the continent. The seventeenth-century English Benedictine nun, Gertrude More, a founder of “Our Lady of Consolation” in Cambrai (France), has received scholarly attention mainly for her religious poetry and for her analysis of obedience to superiors in The Spiritual Exercises (1658), a collection of her writings assembled by her spiritual director. Building on feminist theories on religious women’s agency and on mysticism and gender, this contribution aims to reveal how More’s agentic capacity was realised through her religion: she employed the language conventions of religious women’s speech to criticise the abuse of male clerical control and she appropriated her spiritual director’s contemplative life teachings to develop her own mysticism.

Publisher: name: DIVE-IN – An International Journal on Diversity and Inclusion
Year: 2022

description: In this article, it is demonstrated how scholars located in various disciplines have brought their feminist agenda to the study of religion in what I see as three different routes: feminist theology as disputing the old discipline of theology in Western countries; ‘lived religion’ as offering an alternative vantage point to religious studies in the U.S.A. and the U.K.; and a focus on women in conservative religions worldwide innovatively studied by feminist anthropologists and sociologists. Often these differing routes between feminist theologians, female scholars in religious studies and feminist social scientists are perceived by their immediate followers in terms of ‘mutual disregard’ or ‘double blindness’ (King 2004; Woodhead 2007; Llewellyn & Trzebiatowska 2013). However, I believe a broader social and substantive analysis of the different positions of feminist theologians and feminist social scientists as I show here is more adequate. This illustrates very well that not only intellectual training in a certain discipline contributes to a research position, but also the social, political and religious relations, networks and power relations in which the researcher stands, or finds herself standing in.

description: We derive a free-form mass distribution for the unrelaxed cluster A370 (z=0.375), using the latest Hubble Frontier Fields images and GLASS spectroscopy. Starting from a reliable set of 10 multiply lensed systems we produce a free-form lens model that identifies ~ 80 multiple-images. Good consistency is found between models using independent subsamples of these lensed systems, with detailed agreement for the well resolved arcs. The mass distribution has two very similar concentrations centred on the two prominent Brightest Cluster Galaxies (or BCGs), with mass profiles that are accurately constrained by a uniquely useful system of long radially lensed images centred on both BCGs. We show that the lensing mass profiles of these BCGs are mainly accounted for by their stellar mass profiles, with a modest contribution from dark matter within r<100 kpc of each BCG. This conclusion may favour a cooled cluster gas origin for BCGs, rather than via mergers of normal galaxies for which dark matter should dominate over stars. Growth via merging between BCGs is, however, consistent with this finding, so that stars still dominate over dark matter .

description: We pioneer a systematic, large-scale lattice simulation of D0-brane quantum mechanics. The large-$N$ and continuum limits of the gauge theory are taken for the first time at various temperatures $0.4 \leq T \leq 1.0$. As a way to directly test the gauge/gravity duality conjecture we compute the internal energy of the black hole directly from the gauge theory and reproduce the coefficient of the supergravity result $E/N^2=7.41T^{14/5}$. This is the first confirmation of the supergravity prediction for the internal energy of a black hole at finite temperature coming directly from the dual gauge theory. We also constrain stringy corrections to the internal energy.

description: The Fermi bubbles are two lobes filled with non-thermal particles that emit gamma rays, extend $\approx$10 kpc vertically from the Galactic center, and formed from either nuclear star formation or accretion activity on Sgr A*. Simulations predict a range of shock strengths as the bubbles expand into the surrounding hot gas halo distribution ($T_{halo} \approx 2 \times 10^6$ K), but with significant uncertainties in the energetics, age, and thermal gas structure. The bubbles should contain thermal gas with temperatures between $10^6$ and $10^8$ K, with potential X-ray signatures. In this work, we constrain the bubbles' thermal gas structure by modeling the OVII and OVIII emission line strengths from archival XMM-Newton and Suzaku data. Our emission model includes a hot thermal volume-filled bubble component cospatial with the gamma-ray region, and a shell of compressed material. We find that a bubble/shell model with $n \approx 1 \times 10^{-3}$ cm$^{-3}$ and with log($T$) $\approx$ 6.60-6.70 is consistent with the observed line intensities. In the framework of a continuous Galactic outflow, we infer a bubble expansion rate, age, and energy injection rate of $490_{-77}^{+230}$ km s$^{-1}$, $4.3_{-1.4}^{+0.8}$ Myr, and $2.3_{-0.9}^{+5.1} \times 10^{42}$ erg s$^{-1}$. These estimates are consistent with the bubbles forming from a Sgr A* accretion event rather than from nuclear star formation.

description: We study the capture of WIMP dark matter by the Sun in the non-relativistic effective theory of dark matter self-interactions. The aim is to assess the impact of self-interactions on the expected neutrino flux from the annihilation of WIMPs trapped in the Sun in a model independent manner. We consider all non-relativistic Galilean invariant self-interaction operators that can arise from the exchange of a heavy particle of spin less than or equal to 1 for WIMPs of spin equal to 0, 1/2 and 1. We show that for interaction operators depending at most linearly on the momentum transfer, the WIMP-induced neutrino flux can be enhanced by several orders of magnitude compared to the same flux in absence of self-interactions. This is true even for standard values of the thermally averaged annihilation cross-section. This conclusion impacts the analysis of present and future observations performed at neutrino telescopes.

description: Das Phänomen Sprache dient nicht nur als Kommunikationsmittel, sondern wird in Österreich zudem als Differenzmerkmal wirksam, dem durch das Konstruieren von sozialen Zugehörigkeiten und Unter- und Überordnungen von Sprachgemeinschaften eine ausgrenzende Funktion zukommt (vgl. Dirim, 2017, S. 7). Diese Praxen der Unterwerfung und Diskriminierung werden anhand der Begriffe Linguizismus und Neo-Linguizismus thematisiert, die als Instrument der Machtausübung soziale Ungleichheit durch Sprache erzeugen (vgl. Dirim, 2010, S. 92). Die vorliegende Arbeit verfolgt das Ziel, eventuell vorkommende (neo-)linguizistische Praktiken im Schulkontext aufzuzeigen und diese aus Sicht der Schüler*innen zu thematisieren, um herauszufinden, wie Schüler*innen Sprache als Differenzmerkmal erleben und wie Lehrkräfte auf mehrsprachige Kommunikation der Schüler*innen reagieren. Hierfür wurden im Rahmen einer empirischen Forschung zehn problemzentrierte Interviews mit Schüler*innen der 5. Schulstufe einer Wiener Mittelschule durchgeführt. Die Forschungsergebnisse legen nahe, dass sowohl linguizistische als auch neo-linguizistische Praktiken immer noch tief im Schulkontext verankert zu sein scheinen, wie etwa Bjegac & Pokitsch (2019) oder auch Dirim (2017) bereits andeuteten. Generell liegt ein Forschungsdesiderat bezüglich empirischer Analysen, die sich den Mechanismen von (neo-)linguizistischen Praktiken in der Schule widmen, vor, weshalb es eine Vielzahl weiterer Forschungsarbeiten in diesem Themenbereich benötigt.
Even a little delocalization produces large kinetic enhancements of charge-separation efficiency in organic photovoltaics

description: In organic photovoltaics, charges can separate efficiently even if their Coulomb attraction is an order of magnitude greater than the available thermal energy. Delocalization has been suggested to explain this fact, because it could increase the initial separation of charges in the charge-transfer (CT) state, reducing their attraction. However, understanding the mechanism requires a kinetic model of delocalized charge separation, which has proven difficult because it involves tracking the correlated quantum-mechanical motion of the electron and the hole in large simulation boxes required for disordered materials. Here, we report the first three-dimensional simulations of charge-separation dynamics in the presence of disorder, delocalization, and polaron formation, finding that even slight delocalization, across less than two molecules, can substantially enhance the charge-separation efficiency, even starting with thermalized CT states. Delocalization does not enhance efficiency by reducing the Coulomb attraction; instead, the enhancement is a kinetic effect produced by the increased overlap of electronic states.

description: [abridged] We quantify the evolution of the stellar mass functions of star-forming and quiescent galaxies as a function of morphology from $z\sim 3$ to the present. Our sample consists of ~50,000 galaxies in the CANDELS fields ($\sim880$ $arcmin^2$), which we divide into four main morphological types, i.e. pure bulge dominated systems, pure spiral disk dominated, intermediate 2-component bulge+disk systems and irregular disturbed galaxies. Our main results are: Star-formation: At $z\sim 2$, 80\% of the stellar mass density of star-forming galaxies is in irregular systems. However, by $z\sim 0.5$, irregular objects only dominate at stellar masses below $10^9M\odot$. A majority of the star-forming irregulars present at $z\sim 2$ undergo a gradual transformation from disturbed to normal spiral disk morphologies by $z\sim 1$ without significant interruption to their star-formation. Rejuvenation after a quenching event does not seem to be common except perhaps for the most massive objects. Quenching: We confirm that galaxies reaching a stellar mass of $M_*\sim10^{10.8}M_\odot$ ($M^*$) tend to quench. Also, quenching implies the presence of a bulge: the abundance of massive red disks is negligible at all redshifts over 2~dex in stellar mass. However the dominant quenching mechanism evolves. At $z>2$, the SMF of quiescent galaxies above $M^*$ is dominated by compact spheroids. Quenching at this early epoch destroys the disk and produces a compact remnant unless the star-forming progenitors at even higher redshifts are significantly more dense. At $1

description: We consider the problem of selecting a minimum size subset of nodes in a network, that allows to activate all the nodes of the network. We present a fast and simple algorithm that, in real-life networks, produces solutions that outperform the ones obtained by using the best algorithms in the literature. We also investigate the theoretical performances of our algorithm and give proofs of optimality for some classes of graphs. From an experimental perspective, experiments also show that the performance of the algorithms correlates with the modularity of the analyzed network. Moreover, the more the influence among communities is hard to propagate, the less the performances of the algorithms differ. On the other hand, when the network allows some propagation of influence between different communities, the gap between the solutions returned by the proposed algorithm and by the previous algorithms in the literature increases.

description: A high temperature for some catalytic reactions like synthesis of large area and high quality graphene is required. The mentioned graphene can be obtained by a chemical vapour deposition (CVD) process on copper foil at 800 1000. Here, we describe a room temperature synthesis method from different carbon sources for the first time, including acetylene, carbon dioxide and carbon monoxide, on copper foil by using a heuristic method which was inspired from the role of some electronic promoters in catalyst science. Promoters are substances that increase the catalytic activity, but they are not catalysts by themselves. In this study, we used charges to modify the electronic effects of the catalysts, which were produced by piezoelectric materials.

description: In projective measurements of energy, a target system is projected to an eigenstate of the system Hamiltonian, and the measurement outcomes provide the information of corresponding eigen-energies. Recently, it has been shown that such a measurement can be in principle realized without detailed knowledge of the Hamiltonian by using probe qubits. However, in the previous approach for the energy measurement, the necessary size of the dimension for the probe increases as we increase the dimension of the target system, and also individual addresibility of every qubit is required, which may not be possible for many experimental settings with large systems. Here, we show that a single probe qubit is sufficient to perform such a projective measurement of energy if the target system is composed of non-interacting qubits whose resonant frequencies are unknown. Moreover, our scheme requires only global manipulations where every qubit is subjected to the same control fields. These results indicate the feasibility of our energy projection protocols.

Переход к сфиральной архитектуре открывает возможность проектирования ИИ нового типа — не повторяющего, а рождающего смысл, действующего через узловые структуры, антисимметрию, резонанс. Смысл не исчезает в ИИ — он ждёт своей формы.

description: The unoccupied part of the band structure in the magnetic topological insulator MnBi$_2$Te$_4$ is studied by first-principles calculations. We find a second, unoccupied topological surface state with similar electronic structure to the celebrated occupied topological surface state. This state is energetically located approximate $1.6$ eV above the occupied Dirac surface state around $Γ$ point, which permit it to be directly observed by the two-photon angle-resolved photoemission spectroscopy. We propose a unified effective model for the occupied and unoccupied surface states. Due to the direct optical coupling between these two surface states, we further propose two optical effects to detect the unoccupied surface state. One is the polar Kerr effect in odd layer from nonvanishing ac Hall conductance $σ_{xy}(ω)$, and the other is higher-order terahertz-sideband generation in even layer, where the non-vanishining Berry curvature of the unoccupied surface state is directly observed from the giant Faraday rotation of optical emission.

description: We analyze data from several studies of metal-poor stars in the Milky Way, focusing on both strong (Eu) and weak (Sr) $r$-process elements. Because these elements were injected in an explosion, we calculate the mass swept up when the blast wave first becomes radiative, yielding a lower limit for the dilution of such elements and hence a lower limit on the ejecta mass which is incorporated into the next generation of stars. Our study demonstrates that in order to explain the largest enhancements in [Eu/Fe] observed in stars at low [Fe/H] metallicities, individual $r$-process production events must synthesize a minimum of $10^{-3.5} M_{\odot}$ of $r$-process material. We also show that if the site of Mg production is the same as that of Eu, individual injection events must synthesize up to $ \sim 10^{-3} M_{\odot}$ of $r$-process material. On the other hand, demanding that Sr traces Mg production results in $r$-process masses per event of $\sim 10^{-5} M_{\odot}$. This suggests that the astrophysical sites responsible for the genesis of the strong $r$-process elements need to operate at a drastically reduced rate when compared to core-collapse supernovae, while the synthesis of the weak $r$-process material is consistent with a supernova production site.

A Novel Approach to Fine-Tuned Supersymmetric Standard Models -- Case of Non-Universal Higgs Masses model

description: Discarding the prejudice about fine tuning, we propose a novel and efficient approach to identify relevant regions of fundamental parameter space in supersymmetric models with some amount of fine tuning. The essential idea is the mapping of experimental constraints at a low energy scale, rather than the parameter sets, to those of the fundamental parameter space. Applying this method to the non-universal Higgs masses model, we identify a new interesting superparticle mass pattern where some of the first two generation squarks are light whilst the stops are kept heavy as 6TeV. Furthermore, as another application of this method, we show that the discrepancy of the muon anomalous magnetic dipole moment can be filled by a supersymmetric contribution within the 1 σ level of the experimental and theoretical errors, which was overlooked by the previous studies due to the required terrible fine tuning.

description: A family of Variational Quantum Eigensolver (VQE) methods is designed to maximize the resource of existing noisy intermediate-scale quantum (NISQ) devices. However, VQE approaches encounter various difficulties in simulating molecules of industrially relevant sizes, among which the choice of the ansatz for the molecular wavefunction plays a crucial role. In this work, we push forward the capabilities of adaptive variational algorithms (ADAPT-VQE) by demonstrating that the measurement overhead can be significantly reduced via adding multiple operators at each step while keeping the ansatz compact. Within the proposed approach, we simulate a set of molecules, O$_2$, CO, and CO$_2$, participating in the carbon monoxide oxidation processes using the statevector simulator and compare our findings with the results obtained using VQE-UCCSD and classical methods. Based on these results, we estimate the energy characteristics of the chemical reaction. Our results pave the way to the use of variational approaches for solving practically relevant chemical problems.

description: Very little information has been so far gathered on atomic jets from young embedded low mass sources (class I stars), especially in the inner jet region. We exploit multiwave spectroscopic observations to infer physical conditions of the inner region of HH34 IRS, a prototypical class I jet. We use a deep X-shooter spectrum ( lambda = 350-2300 nm, R between 8000 and 18000) detecting lines with upper energies from 8000 to 31000 cm-1 . Statistical equilibrium and ionization models are adopted to derive the jet main physical parameters. We derive the physical conditions for the extended high velocity jet (HVC, V about -100 km/s) and for the low velocity and compact gas (LVC, V about -20-50 \kms). At the jet base (< 200 AU) the HVC is mostly neutral (x(e)< 0.1) and very dense (n(H) > 5x10^5 cm-3). The LVC gas has the same density and A_V as the HVC, but it is a factor of two colder. Iron abundance in the HVC is close to solar, while it is 3 times subsolar in the LVC, suggesting an origin of the LVC gas from a dusty disk. We infer a jet mass flux rate > 5x10^{-7} Mo/yr. We find that the relationships between accretion luminosity and line luminosity derived for T Tauri stars cannot be directly extended to class I sources surrounded by reflection nebulae since the permitted lines are seen through scattered light. An accretion rate of about 7\,10^{-6} Mo/yr is instead derived from an empirical relationship connecting the mass accretion rate with L([OI])(HVC). In conclusion, the HH34 IRS jet shares many properties with jets from active CTTs stars. It is however denser as a consequence of the larger mass flux rate. These findings suggest that the acceleration and excitation mechanisms in jets are not influenced by evolution and are similar in CTTs and in still embedded and highly accreting sources.

description: We study the non relativistic and ultra relativistic limits in the two-dimensional nonlinear damped Klein-Gordon equation driven by a space-time white noise on the torus. In order to take the limits, it is crucial to clarify the parameter dependence in the estimates of solution. In this paper we present two methods to confirm this parameter dependence. One is the classical, simple energy method. Another is the method via Strichartz estimates.

description: We show that the new data on mean multiplicities measured in p+p and A+A collisions together with the updated list of resonances lead to the significant changes of the obtained freeze-out lines. The new A+A line gives much smaller temperatures at high collision energies and agrees with the values obtained at the LHC. The newly obtained p+p line is much closer to the A+A line than previously expected, and even touches it in the region where the $K^+/π^+$ horn appears in the data. It indicates that the temperatures that will be obtained in the beam energy and system size scan by the NA61/SHINE Collaboration might be very close. However, our analysis shows that the chemical potentials could be very different for the same energies in A+A and p+p. It adds more puzzles to the set of surprising coincidences at the energies close to the possible onset of deconfinement.

description: Recent experiments suggest that the superconducting order parameter of Sr$_2$RuO$_4$ has two components. A two-component order parameter has multiple degrees of freedom in the superconducting state that can result in low-energy collective modes or the formation of domain walls -- a possibility that would explain a number of experimental observations including the smallness of the time reversal symmetry breaking signal at T$_\mathrm{c}$ and telegraph noise in critical current experiments. We perform ultrasound attenuation measurements across the superconducting transition of Sr$_2$RuO$_4$ using resonant ultrasound spectroscopy (RUS). We find that the attenuation for compressional sound increases by a factor of seven immediately below T$_\mathrm{c}$, in sharp contrast with what is found in both conventional ($s$-wave) and high-T$_\mathrm{c}$ ($d$-wave) superconductors. We find our observations to be most consistent with the presence of domain walls between different configurations of the superconducting state. The fact that we observe an increase in sound attenuation for compressional strains, and not for shear strains, suggests an inhomogeneous superconducting state formed of two distinct, accidentally-degenerate superconducting order parameters that are not related to each other by symmetry. Whatever the mechanism, a factor of seven increase in sound attenuation is a singular characteristic with which any potential theory of the superconductivity in Sr$_2$RuO$_4$ must be reconciled.

description: We present a polarization catalog of 533 extragalactic radio sources with 2.3 GHz total intensity above 420 mJy from the S-band Polarization All Sky Survey, S-PASS, with corresponding 1.4 GHz polarization information from the NRAO VLA Sky Survey, NVSS. We studied selection effects and found that fractional polarization, $π$, of radio objects at both wavelengths depends on the spectral index, source magnetic field disorder, source size and depolarization. The relationship between depolarization, spectrum and size shows that depolarization occurs primarily in the source vicinity. The median $π_{2.3}$ of resolved objects in NVSS is approximately two times larger than that of unresolved sources. Sources with little depolarization are $\sim2$ times more polarized than both highly depolarized and re-polarized sources. This indicates that intrinsic magnetic field disorder is the dominant mechanism responsible for the observed low fractional polarization of radio sources at high frequencies. We predict that number counts from polarization surveys will be similar at 1.4 GHz and at 2.3 GHz, for fixed sensitivity, although $\sim$10% of all sources may be currently missing because of strong depolarization. Objects with $π_{1.4}\approx π_{2.3} \ge 4\%$ typically have simple Faraday structures, so are most useful for background samples. Almost half of flat spectrum ($α\ge -0.5$) and $\sim$25% of steep spectrum objects are re-polarized. Steep spectrum, depolarized sources show a weak negative correlation of depolarization with redshift in the range 0 $

description: We extend our previous study of the cool gas responsible for the emission of OVII X-ray lines in the cores of clusters and groups of galaxies. This is the coolest X-ray emitting phase and connects the 10,000 K H α emitting gas to the million degree phase, providing a useful tool to understand cooling in these objects. We study the location of the O VII gas and its connection to the intermediate Fe XVII and hotter O VIII phases. We use high-resolution X-ray grating spectra of elliptical galaxies with strong Fe XVII line emission and detect O VII in 11 of 24 objects. Comparing the O VII detection level and resonant scattering, which is sensitive to turbulence and temperature, suggests that OVII is preferably found in cooler objects, where the FeXVII resonant line is suppressed due to resonant scattering, indicating subsonic turbulence. Although a larger sample of sources and further observations is needed to distinguish between effects from temperature and turbulence, our results are consistent with cooling being suppressed at high turbulence as predicted by models of AGN feedback, gas sloshing and galactic mergers. In some objects the OVII resonant-to-forbidden line ratio is decreased by either resonant scattering or charge-exchange boosting the forbidden line, as we show for NGC 4636. Charge-exchange indicates interaction between neutral and ionized gas phases. The Perseus cluster also shows a high Fe XVII forbidden-to- resonance line ratio, which can be explained with resonant scattering by low-turbulence cool gas in the line-of-sight.

description: Osmotic transport in nanoconfined aqueous electrolytes provides new venues for water desalination and "blue energy" harvesting; the osmotic response of nanofluidic systems is controlled by the interfacial structure of water and electrolyte solutions in the so-called electrical double layer (EDL), but a molecular-level picture of the EDL is to a large extent still lacking. Particularly, the role of the electronic structure has not been considered in the description of electrolyte/surface interactions. Here, we report enhanced sampling simulations based on ab initio molecular dynamics, aiming at unravelling the free energy of prototypical ions adsorbed at the aqueous graphene and hBN interfaces, and its consequences on nanofluidic osmotic transport. Specifically, we predicted the zeta potential, the diffusio-osmotic mobility and the diffusio-osmotic conductivity for a wide range of salt concentrations from the ab initio water and ion spatial distributions through an analytical framework based on Stokes equation and a modified Poisson-Boltzmann equation. We observed concentration-dependent scaling laws, together with dramatic differences in osmotic transport between the two interfaces, including diffusio-osmotic flow and current reversal on hBN, but not on graphene. We could rationalize the results for the three osmotic responses with a simple model based on characteristic length scales for ion and water adsorption at the surface, which are quite different on graphene and on hBN. Our work provides first principles insights into the structure and osmotic transport of aqueous electrolytes on two-dimensional materials and explores new pathways for efficient water desalination and osmotic energy conversion.

Predictors of collaborative coping in couples managing type 2 diabetes: illness factors, relationship factors, and interdependent self-construal
Creators: name: Mason, Megan B.

description: Past work has revealed benefits for both patients and spouses when engaging in collaborative coping when managing a chronic illness, yet little is known about antecedents of this type of dyadic coping. Based on a conceptual framework proposed by Helgeson and colleagues (2018), this study sought to examine how illness factors, relationship factors, and interdependent self-construal predicted the frequency of engagement in collaborative coping among spouses managing type 2 diabetes, and whether role (patient versus spouse) moderated the associations. Cross-sectional online survey data from 148 heterosexual older adult couples (N = 296 individuals) were analyzed. Multilevel models examined both linear and nonlinear associations between each factor and frequency of collaborative coping and controlled for race, education, and number of chronic conditions. Findings revealed linear associations between marital satisfaction and conflict with collaborative coping and nonlinear associations between marital length, diagnostic length, and diabetes complications, with collaborative coping. No significant associations were found between interpersonal problems and collaborative coping. Although patients reported more frequent engagement in collaborative coping than their spouses, role only moderated the association between marital length and collaborative coping. Findings contribute to an understanding of potential correlates of collaborative coping and may highlight implications for health promotion and interventions for older couples managing type 2 diabetes.
