description: We show that the spectral weights $W_{m\vec K}(\vec k)$ used for the unfolding of two-component spinor eigenstates $| {ψ_{m\vec K}^\mathrm{SC}} > = | α> | {ψ_{m\vec{K}}^\mathrm{SC, α}} > + | β> | {ψ_{m\vec{K}}^\mathrm{SC, β}} >$ can be decomposed as the sum of the partial spectral weights $W_{m\vec{K}}^μ(\vec k)$ calculated for each component $μ= α, β$ independently, effortlessly turning a possibly complicated problem involving two coupled quantities into two independent problems of easy solution. Furthermore, we define the unfolding-density operator $\hatρ_{\vec{K}}(\vec{k}_{i}; \, \varepsilon)$, which unfolds the primitive cell expectation values $φ^{pc}(\vec{k}; \varepsilon)$ of any arbitrary operator $\mathbf{\hatφ}$ according to $φ^{pc}(\vec{k}_{i}; \varepsilon) = \mathit{Tr}(\hatρ_{\vec{K}}(\vec{k}_{i}; \, \varepsilon)\,\,\hatφ)$. As a proof of concept, we apply the method to obtain the unfolded band structures, as well as the expectation values of the Pauli spin matrices, for prototypical physical systems described by two-component spinor eigenfunctions.

description: Advancements in electrochemical energy storage devices such as batteries and supercapacitors are vital for a sustainable energy future. Significant progress has been made in developing novel materials for these devices, but less attention has focused on developments in electrode and device manufacturing. While electrodes are traditionally made through slurry casting of electrochemically active material, advanced manufacturing techniques enable patterning of novel electrode architectures and control of device geometries in real-time, which can potentially result in electrodes with increased loading, improved electrochemical performance, and added functionality, such as flexibility and wearability. These inexpensive methods are particularly suited for lab-scale research and start-up companies, as they enable rapid prototyping without a full device production line. The present review describes three main methods of advanced manufacturing (inkjet printing, direct ink writing, and laser-induced graphene techniques) and evaluates the performance of batteries and supercapacitors fabricated via these methods in comparison to traditionally manufactured devices.

Origins and development of a “Pygmalion and Galatea” motif in writings of Tanizaki Jun’ichirō

description: The main goal of the article is to define the genesis of the motif constantly appearing in the writings of Tanizaki Jun’ichirō and referred to as “Pygmalion and Galatea” motif. Using the comparative and historical-biographical methods of literature studies it is possible to detect whether this motif has actual connection to “Pygmalion” myth and the works of O. Wilde and B. Shaw influenced by that myth. An influence of the classic Japanese literature’s motif reminiscent of “Pygmalion and Galatea” one was also observed in the writings of Tanizaki. The modification of the motif is attributed to the “Return to Japan” period in life of the writer, when he was disenchanted by the results of westernization and modernization of Japan. The images of “rebellious Galatea” (“The Tattooer”, “Naomi”) was created when Tanizaki was deeply interested in Western literature. The archetype of “obedient Galatea” (“Some Prefer Nettles”) appeared when the writer turned his attention to Japanese tradition. The motif of “Pygmalion and Galatea” is used in Tanizaki’s writings continuously, transforms along with the writer’s cultural and literary preferences of the moment and helps to intensify the main conflicts in his works such as West and Japan, tradition and modernity, art and artist.
The pointer basis and the feedback stabilization of quantum systems

description: The dynamics for an open quantum system can be `unravelled' in infinitely many ways, depending on how the environment is monitored, yielding different sorts of conditioned states, evolving stochastically. In the case of ideal monitoring these states are pure, and the set of states for a given monitoring forms a basis (which is overcomplete in general) for the system. It has been argued elsewhere [D. Atkins et al., Europhys. Lett. 69, 163 (2005)] that the `pointer basis' as introduced by Zurek and Paz [Phys. Rev. Lett 70, 1187(1993)], should be identified with the unravelling-induced basis which decoheres most slowly. Here we show the applicability of this concept of pointer basis to the problem of state stabilization for quantum systems. In particular we prove that for linear Gaussian quantum systems, if the feedback control is assumed to be strong compared to the decoherence of the pointer basis, then the system can be stabilized in one of the pointer basis states with a fidelity close to one (the infidelity varies inversely with the control strength). Moreover, if the aim of the feedback is to maximize the fidelity of the unconditioned system state with a pure state that is one of its conditioned states, then the optimal unravelling for stabilizing the system in this way is that which induces the pointer basis for the conditioned states. We illustrate these results with a model system: quantum Brownian motion. We show that even if the feedback control strength is comparable to the decoherence, the optimal unravelling still induces a basis very close to the pointer basis. However if the feedback control is weak compared to the decoherence, this is not the case.

description: A regular polyhedron of type {p, q} has at least 2pq flags, and it is called tight if it has exactly 2pq flags. The values of p and q for which there exist tight orientably regular polyhedra were previously known. We determine for which values of p and q there is a tight non-orientably regular polyhedron of type {p, q}. Furthermore, we completely classify tight regular polyhedra in terms of their automorphism groups.

description: English-language reviews of translations of prose fiction are dominated by a “belletristic” approach whereby the artistic features of the translation text are assessed with little reference to its original. Such an approach fails to provide an adequate evaluation of the merits, drawbacks or “losses” in the translation under review. The author of the article offers a method of concrete comparative translation discourse analysis (CTDA) of originals and their translations based on their specific lexical, structural-communicative, stylistic, pragmatic, and sociocultural properties. At the lexical level, the objects of comparison of the original text and its translation are the following elements of denotative and connotative meaning: denotation (1) denotative word-sense core; (2) denotative word-sense periphery; connotation the “emotive charge” of the sense core, including (3) the nature of emotion and (4) its intensity; (5) the evaluative connotation of the word-sense (“the author’s attitude”); (6) functional style reference; (7) dialectal reference (temporal/generational, regional, and sociocultural); (8) comparative frequency of occurrence in a particular functional style; (9) word-sense pragmatics (word-sense comparative “metaphoricity,” its “political correctness,” “cumbersomeness” and some other features). At the predication level (sentence and clause), it is possible to single out 5-7 key (constant) syntactic and communicative “discrepancies” between Russian and English, which get rendered in either language with the help of 5-7 constant translation models. The assessment of the overall pragmatics of the translation text consists in determining the degrees of the neutralization, “domestication” (“naturalization”/localization), “contamination,” “foreignization,” and stylization of the original text. The comprehensive “impression” of the quality of a translation in the mind of the translation analyst, based on the analyses at the three levels (lexical, predication, and pragmatic), constitutes the tertium comparationis of the proposed analytical approach. Given the relative “fuzziness” and variance in individual perceptions of textual meaning, the categories of analysis and assessment proposed in this article are not absolute, belonging as they do to the qualitative methods of comparative translation studies. The article contains examples illustrating the author’s conceptual framework.

description: We investigate the structure and dynamics of a rotating superfluid Bose-Fermi mixture (SBFM) made of superfluid bosons and two-component (spin up and down) superfluid fermions. A ground-state phase diagram for the nonrotating case of a SBFM with specific parameters is given, where the ground-state configuration of a nonrotating SBFM is mainly determined by the boson-fermion interaction. For the rotating case of a SBFM with a sufficiently large rotation frequency, we show that the system supports a mixed phase and three typical layer separated phases. In particular, the visible vortex formation in the fermionic superfluid exhibits a remarkable hysteresis effect during the dynamical evolution of a rotating SBFM, which is evidently different from the case of rotating two-component Bose-Einstein condensates.

description: We use the Zurich ENvironmental Study (ZENS) database to investigate the environmental dependence of the merger fraction $Γ$ and merging galaxy properties in a sample of ~1300 group galaxies with $M>10^{9.2}M_\odot$ and 0.0510^{13.5} M_\odot$ relative to less massive systems, indicating a suppression of merger activity in large potential wells. In the fiducial case of relaxed groups only, we measure a variation $ΔΓ/Δ\log (M_{HALO}) \sim - 0.07$ dex$^{-1}$, which is almost independent of galaxy mass and merger stage. At galaxy masses $>10^{10.2} M_\odot$, most mergers are dry accretions of quenched satellites onto quenched centrals, leading to a strong increase of $Γ$ with decreasing group-centric distance at these mass scales.Both satellite and central galaxies in these high mass mergers do not differ in color and structural properties from a control sample of nonmerging galaxies of equal mass and rank. At galaxy masses $<10^{10.2} M_\odot$, where we mostly probe satellite-satellite pairs and mergers between star-forming systems, close pairs (projected distance $<10-20$ kpc) show instead $\sim2\times$ enhanced (specific) star formation rates and $\sim1.5\times$ larger sizes than similar mass, nonmerging satellites. The increase in both size and SFR leads to similar surface star-formation densities in the merging and control-sample satellite populations.

description: Markov-modulated fluid queues are popular stochastic processes frequently used for modelling real-life applications. An important performance measure to evaluate in these applications is their steady-state behaviour, which is determined by the stationary density. Computing it requires solving a (nonsymmetric) M-matrix algebraic Riccati equation, and indeed computing the stationary density is the most important application of this class of equations. Xue, Xu and Li [Numer. Math., 2012] provided a componentwise first-order perturbation analysis of this equation, proving that the solution can be computed to high relative accuracy even in the smallest entries, and suggested several algorithms for computing it. An important step in all proposed algorithms is using so-called triplet representations, which are special representations for M-matrices that allow for a high-accuracy variant of Gaussian elimination, the GTH-like algorithm. However, triplet representations for all the M-matrices needed in the algorithm were not found explicitly. This can lead to an accuracy loss that prevents the algorithms to converge in the componentwise sense. In this paper, we focus on the structured doubling algorithm, the most efficient among the proposed methods in Xue et al., and build upon their results, providing (i) explicit and cancellation-free expressions for the needed triplet representations, allowing the algorithm to be performed in a really cancellation-free fashion; (ii) an algorithm to evaluate the final part of the computation to obtain the stationary density; and (iii) a componentwise error analysis for the resulting algorithm, the first explicit one for this class of algorithms. We also present numerical results to illustrate the accuracy advantage of our method over standard (normwise-accurate) algorithms.

Further structural information about End $R$ is established including that Aut $Γ$ arises in uncountably many ways as a Schützenberger group. Similar results are proved for the countable universal directed graph and the countable universal bipartite graph.

description: In Bangladesh the safety precaution and working condition of tannery workers are very disappointing. The tannery workers are always coming in contact with different chemical exposure and different heavy metals are inserting into their body organs. The aim of this study was to determine selected heavy metal levels including cadmium (Cd), Chromium (Cr) and lead (Pb) in scalp Hair of tannery workers and find out the Relationship between the chromium concentration in workers hair and their working duration. Human hair sample of different tannery worker were collected from different tanneries in Bangladesh and samples of individual were analyzedfor heavy metals (Cd, Cr and Pb) by Flame Atomic Absorption Spectrophotometric technique (AAS). The results of replicate analysis shows the following mean concentrations in (mg/kg): Cd = 0.04± 0.085, Cr = 5.85 ± 0.8391, Pb = 1.3 ± 0.0465. Comparing with others study around the world, the result shows that the presence of chromium is in very large amount in Bangladeshi tannery workers hair, lead in relatively large amount and cadmium is in small amount.

description: An anisotropic thermal plasma phase of a strongly coupled gauge theory can be holographically modelled by an anisotropic AdS black hole. The temperature and anisotropy parameter of the AdS black hole background of interest [1] is specified by the location of the horizon and the value of the Dilaton field at the horizon. Interestingly, for the first time, we obtain two functions for the values of the horizon and Dilaton field in terms of the temperature and anisotropy parameter. Then by introducing a number of spinning probe D7-branes in the anisotropic background, we compute the value of the chiral magnetic effect (CME). We observe that in the isotropic and anisotropic plasma the value of the CME is equal for the massless quarks. However, at fixed temperature, raising the anisotropy in the system will increase the value of the CME for the massive quarks.

description: The Type Ia supernova SN 2011fe is one of the closest supernovae of the past decades. Due to its proximity and low dust extinction, this object provides a very rare opportunity to study the extremely late time evolution ($>900$ days) of thermonuclear supernovae. In this Letter, we present our photometric data of SN 2011fe taken at an unprecedented late epoch of $\approx 930$ days with GMOS-N mounted on the Gemini North telescope ($g=23.43 \pm 0.28$, $r=24.14 \pm 0.14$, $i=23.91 \pm 0.18$, and $z=23.90 \pm 0.17$) to study the energy production and retention in the ejecta of SN 2011fe. Together with previous measurements by other groups, our result suggests that the optical supernova light curve can still be explained by the full thermalization of the decay positrons of Co56. This is in spite of theoretical predicted effects (e.g. infrared catastrophe, positron escape, and dust) that advocate a substantial energy redistribution and/or loss via various processes that result in a more rapid dimming at these very late epochs.

description: We analyze the partition function of two dimensional Yang-Mills theory on a family of surfaces of infinite genus. These surfaces have a recursive structure, which was used by one of us to compute the partition function that results in a generalized Migdal formula. In this paper we study the `small area' (weak coupling) expansion of the partition function, by exploiting the fact that the generalized Migdal formula is analytic in the (complexification of the) Euler characteristic. The structure of the perturbative part of the weak coupling expansion suggests that the moduli space of flat connections (of the SU(2) and SO(3) theories) on these infinite genus surfaces are well defined, perhaps in an appropriate regularization.

Privacy Amplification in the Isolated Qubits Model

description: Isolated qubits are a special class of quantum devices, which can be used to implement tamper-resistant cryptographic hardware such as one-time memories (OTM's). Unfortunately, these OTM constructions leak some information, and standard methods for privacy amplification cannot be applied here, because the adversary has advance knowledge of the hash function that the honest parties will use. In this paper we show a stronger form of privacy amplification that solves this problem, using a fixed hash function that is secure against all possible adversaries in the isolated qubits model. This allows us to construct single-bit OTM's which only leak an exponentially small amount of information. We then study a natural generalization of the isolated qubits model, where the adversary is allowed to perform a polynomially-bounded number of entangling gates, in addition to unbounded local operations and classical communication (LOCC). We show that our technique for privacy amplification is also secure in this setting.

description: Vor dem Hintergrund einer Perspektive auf Sprache im Sinne einer sozialen Praxis untersucht diese Arbeit das Masterstudium Lehramt Deutsch am Institut für Germanistik der Universität Wien als Kontext des Spracherlebens (in Anlehnung an Brigitta Busch) von vier niederösterreichischen Studierenden. Methodisch stützt sich die Untersuchung auf die qualitativ-inhaltsanalytische Auswertung von sprachbiographisch akzentuierten Interviews, die mit den Gewährspersonen (zwei davon weiblich, zwei männlich) geführt wurden. Die Ergebnisse zeigen, dass einerseits gesamtgesellschaftlich verankerte Konventionen respektive soziale Bedeutungen hinsichtlich eines kontextsensitiven, domänenspezifisch situativ/funktional determinierten standard- bzw. nonstandardsprachlichen Kommunizierens einen wesentlichen Einfluss auf Lehrende und Studierende und ihren Sprachgebrauch im Rahmen des betreffenden Studiums (sowie auf einschlägige Wahrnehmungen und Einstellungen der interviewten Gewährspersonen) ausüben. Andererseits lässt sich das Studium insofern als spezifischer Kontext des Spracherlebens der Proband*innen charakterisieren, als diese Veränderungen ihres Sprachbewusstseins und Sprachverhaltens nicht nur reflektieren, sondern dezidiert auf die (sprach-)wissenschaftliche Beschäftigung mit Sprache zurückführen.

description: The existence of envelopes is studied for systems of differential equations in connection with the method of asymptotic splittings which allows to determine the singularity structure of the solutions. The result is applied to braneworlds consisting of a 3-brane in a five-dimensional bulk, in the presence of an analog of a bulk perfect fluid parametrizing a generic class of bulk matter. We find that all flat brane solutions suffer from a finite distance singularity contrary to previous claims. We then study the possibility of avoiding finite distance singularities by cutting the bulk and gluing regular solutions at the position of the brane. Further imposing physical conditions such as finite Planck mass on the brane and positive energy conditions on the bulk fluid, excludes however this possibility, as well.

description: The lightest baryon octet is studied within a covariant and confining Nambu--Jona-Lasinio model. By solving the relativistic Faddeev equations including scalar and axialvector diquarks, we determine the masses and axial charges for ΔS = 0 transitions. For the latter the degree of violation of SU(3) symmetry arising because of the strange spectator quark(s) is found to be up to 10%.

A new approach to determine optically thick H2 cooling and its effect on primordial star formation

description: We present a new method for estimating the H2 cooling rate in the optically thick regime in simulations of primordial star formation. Our new approach is based on the TreeCol algorithm, which projects matter distributions onto a spherical grid to create maps of column densities for each fluid element in the computational domain. We have improved this algorithm by using the relative gas velocities, to weight the individual matter contributions with the relative spectral line overlaps, in order to properly account for the Doppler effect. We compare our new method to the widely used Sobolev approximation, which yields an estimate for the column density based on the local velocity gradient and the thermal velocity. This approach generally underestimates the photon escape probability, because it neglects the density gradient and the actual shape of the cloud. We present a correction factor for the true line overlap in the Sobolev approximation and a new method based on local quantities, which fits the exact results reasonably well during the collapse of the cloud, with the error in the cooling rates always being less than 10%. Analytical fitting formulae fail at determining the photon escape probability after formation of the first protostar (error of 40%) because they are based on the assumption of spherical symmetry and therefore break down once a protostellar accretion disc has formed. Our method yields lower temperatures and hence promotes fragmentation for densities above 10^{10}/ccm at a distance of 200AU from the first protostar. Since the overall accretion rates are hardly affected by the cooling implementation, we expect Pop III stars to have lower masses in our simulations, compared to the results of previous simulations that used the Sobolev approximation.

description: During galaxy mergers the gas falls to the center, triggers star formation, and feeds the rapid growth of supermassive black holes (SMBHs). SMBHs respond to this fueling by supplying energy back to the ambient gas. Numerical studies suggest that this feedback is necessary to explain why the properties of SMBHs and the formation of bulges are closely related. This intimate link between the SMBH's mass and the large scale dynamics and luminosity of the host has proven to be a difficult issue to tackle with simulations due to the inability to resolve all the relevant length scales simultaneously. In this paper we simulate SMBH growth at high-resolution with {\it FLASH}, accounting for the gravitational focusing effects of nuclear star clusters (NSCs), which appear to be ubiquitous in galactic nuclei. In the simulations, the NSC core is resolved by a minimum cell size of about 0.001 pc or approximately $10^{-3}$ of the cluster's radius. We discuss the conditions required for effective gas funneling to occur, which are mainly dominated by a relationship between NSC velocity dispersion and the local sound speed, and provide a sub-grid prescription for the augmentation of central SMBH accretion rates in the presence of NSCs. For the conditions expected to persist in the centers of merging galaxies, the resultant large central gas densities in NSCs should produce drastically enhanced embedded SMBH accretion rates - up to an order of magnitude increase can be achieved for gas properties resembling those in large-scale galaxy merger simulations. This will naturally result in faster black hole growth rates and higher luminosities than predicted by the commonly used Bondi-Hoyle-Lyttleton accretion formalism.

description: The Fermi surface of a metal is the fundamental basis from which its properties can be understood. In underdoped cuprate superconductors, the Fermi surface undergoes a reconstruction that produces a small electron pocket, but whether there is another, as yet undetected portion to the Fermi surface is unknown. Establishing the complete topology of the Fermi surface is key to identifying the mechanism responsible for its reconstruction. Here we report the discovery of a second Fermi pocket in underdoped YBa2Cu3Oy, detected as a small quantum oscillation frequency in the thermoelectric response and in the c-axis resistance. The field-angle dependence of the frequency demonstrates that it is a distinct Fermi surface and the normal-state thermopower requires it to be a hole pocket. A Fermi surface consisting of one electron pocket and two hole pockets with the measured areas and masses is consistent with a Fermi-surface reconstruction caused by the charge-density-wave order observed in YBa2Cu3Oy, provided other parts of the reconstructed Fermi surface are removed by a separate mechanism, possibly the pseudogap.

description: We consider metrics related to each other by functionals of a scalar field $φ(x)$ and it's gradient $\nabla φ(x)$, and give transformations of some key geometric quantities associated with such metrics. Our analysis provides useful and elegant geometric insights into the roles of {\it conformal} and {\it non-conformal} metric deformations in terms of intrinsic and extrinsic geometry of $φ$-foliations. As a special case, we compare {\it conformal} and {\it disformal} transforms to highlight some non-trivial scaling differences. We also study the geometry of {\it equi-geodesic} surfaces formed by points $p$ at constant geodesic distance $σ(p,P)$ from a fixed point $P$, and apply our results to a specific disformal geometry based on $σ(p,P)$ which was recently shown to arise in the context of spacetime with a minimal length.

title: Pinkwashing oder Solidarität?
Creators: name: Wagner, Roman
Year: 2021

description: Die gesellschaftliche Akzeptanz der LGBTQ+ Community nimmt in zahlreichen Staaten seit einigen Jahren rasant zu. Aus diesem Grund erkennen stets mehr Unternehmen das Umsatzpotential durch eine direkte Ansprache dieser Zielgruppe, beschränken ihre Werbeaktivitäten dabei jedoch oftmals auf den Monat Juni. Für viele Konsumentinnen und Konsumenten stellt sich folglich die Frage, ob LGBTQ+ freundliche Werbemaßnahmen Solidarität mit der LGBTQ+ Community vermitteln wollen oder lediglich Pinkwashing (ausnutzen und vorspielen eines LGBTQ+ positiven Images) betreiben. Mittels der Forschungsfrage „Wie nehmen Konsumentinnen und Konsumenten LGBTQ+ freundliche Werbemaßnahmen wahr und durch welche Faktoren kann eine Wahrnehmung als solidarisch erreicht werden? Wie beeinflussen diese Faktoren folglich die daraus resultierende Kaufentscheidung?“ wurden erste Erkenntnisse in diesem Bereich gewonnen. Anhand der inhaltlich strukturierenden Inhaltsanalyse nach Udo Kuckartz (2018) wurden 12 durchgeführte Interviews mit 5 homosexuellen Männern sowie 7 heterosexuellen Personen ausgewertet und deren Ergebnisse anschließend besprochen. Dabei konnte unter anderem festgestellt werden, dass Konsument:innen glaubwürdige Werbungen nicht folglich auch als solidarisch empfinden, sondern hierfür additive Faktoren wie Mut, Zusammenhalt und Rücksichtnahme benötigt werden. Ebenso kam es zu dem Ergebnis, dass sich Boykott- oder Buykottentscheidungen als solidarisches Handeln verstehen und die Kaufentscheidung mitbeeinflussen.

description: We study integrable non-degenerate Monge-Ampere equations of Hirota type in 4D and demonstrate that their symmetry algebras have a distinguished graded structure, uniquely determining the equations. This is used to deform these heavenly type equations into new integrable PDE of the second order with large symmetry pseudogroups. We classify the obtained symmetric deformations and discuss self-dual hyper-Hermitian geometry of their solutions, which encode integrability via the twistor theory.
description: This version is updated with an appendix about multi-component extensions of the integrable equations. Our deformations can be considered as reductions of such extensions (as they are reductions of the self-duality equation), but we stress that second order deformations carry the natural geometry which encodes integrability. We also expanded the introduction a bit

description: The most studied mechanism of inflationary magnetogenesis relies on the time-dependence of the coefficient of the gauge kinetic term $F_{μν}\,{F}^{μν}$. Unfortunately, only extremely finely tuned versions of the model can consistently generate the cosmological magnetic fields required by observations. We propose a generalization of this model, where also the pseudoscalar invariant $F_{μν}\,\tilde{F}^{μν}$ is multiplied by a time dependent function. The new parity violating term allows more freedom in tuning the amplitude of the field at the end of inflation. Moreover, it leads to a helical magnetic field that is amplified at large scales by magnetohydrodynamical processes during the radiation dominated epoch. As a consequence, our model can satisfy the observational lower bounds on fields in the intergalactic medium, while providing a seed for the galactic dynamo, if inflation occurs at an energy scale ranging from $10^5$ to $10^{10}$ GeV. Such energy scale is well below that suggested by the recent BICEP2 result, if the latter is due to primordial tensor modes. However, the gauge field is a source of tensors during inflation and generates a spectrum of gravitational waves that can give a sizable tensor to scalar ratio $r={\cal O}(0.2)$ even if inflation occurs at low energies. This system therefore evades the Lyth bound. For smaller values of $r$, lower values of the inflationary energy scale are required. The model predicts fully helical cosmological magnetic fields and a chiral spectrum of primordial gravitational waves.
