Die Debatten um die Montanunion: Gewerkschaften und europäische Integration in den 1950er Jahren
Creators: name: Bühlbäcker, Bernd
Publisher: name: Moving the Social
Year: 2015

description: The historiography of (early) European Integration concerning the role of trade unionism is still lacking severe historical research. Neither do we know which role national trade unions and their umbrella organisations played, nor do we have detailed studies of their impact on the European Integration process in the 1950s. The author tries to analyse and evaluate early attempts, conceptions and ideas of the main German umbrella organisation, the DGB, and the most influential trade unions of that time, the steal and mining unions IG Metall and IG Bergbau, towards European integration. Beside that the author imbeds his case study into the social, political and economic background of the 1950s when national interests did not necessarily mean mutual interests and also did not cope with supranational ambitions of the European Coal and Steel Community.

Stylistic normalisation, convergence and cross-linguistic interference in translation: The case of the Czech transgressive
Creators: name: Nádvorníková, Olga
Publisher: name: Zenodo
Year: 2021
Subjects: subject: https://glottolog.org/resource/languoid/id/czec1258

description: The Czech transgressive is a non-finite verb form belonging to the cross-linguistic converb category. In contrast with other converbs (e.g. Romance gerundio or the Russian деепричастие), the Czech transgressive has a strong stylistic mark and is very rare in contemporary language. Using a parallel (multilingual) corpus and
 a comparable corpus of translated and non-translated Czech, the paper investigates the differences in the frequency of the transgressive in translated and non-translated fiction and non-fiction. The data show the effect of stylistic normalisation in fiction, but not in non-fiction. The results of the potential effect of cross-linguistic interference are less conclusive, indicating that a thorough contrastive analysis of different language pairs is required first. Finally, the effect of convergence was observed neither in fiction nor in non-fiction.

description: We report the discovery of propylene (also called propene, CH_2CHCH_3) with the IRAM 30-m radio telescope toward the dark cloud TMC-1. Propylene is the most saturated hydrocarbon ever detected in space through radio astronomical techniques. In spite of its weak dipole moment, 6 doublets (A and E species) plus another line from the A species have been observed with main beam temperatures above 20 mK. The derived total column density of propylene is 4 10^13 cm^-2, which corresponds to an abundance relative to H_2 of 4 10^-9, i.e., comparable to that of other well known and abundant hydrocarbons in this cloud, such as c-C_3H_2. Although this isomer of C_3H_6 could play an important role in interstellar chemistry, it has been ignored by previous chemical models of dark clouds as there seems to be no obvious formation pathway in gas phase. The discovery of this species in a dark cloud indicates that a thorough analysis of the completeness of gas phase chemistry has to be done.

description: Ce mémoire a pour but d’apporter un éclairage sur les raisons qui rendent la collaboration entre les parents et les enseignants si compliquée à mettre en place bien que les études prouvent les bienfaits de celle-ci pour les élèves. Nous prendrons en compte trois pôles qui s’articulent entre eux. Il s’agit de la communication et des pratiques communicatives, de l’implication des enseignants, ainsi que de la collaboration et de ses différentes composantes. Nous tenterons de répondre à la question de recherche : en quoi l’implication des enseignants, au travers de leurs pratiques communicatives, influence-t- elle la qualité de la collaboration avec les parents ? Dans le but de mener à bien ce travail nous avons adapter un modèle de collaboration qui s’articule autour des trois pôles mentionnés plus haut. Le postulat de départ pour ce travail est que l’implication et la collaboration n’existe que lorsque la communication respecte certaines conditions. Afin d’y répondre, nous procéderons à une analyse qualitative qui se base sur l’entretien d’une enseignante en 5-6 et d’une autre en 7-8 de nos classes de stage respectives. Nous nous concentrerons uniquement sur les enseignants et leurs réponses. Le modèle que nous avons élaboré n’est pas une science exacte car il a été utilisé seulement à deux reprises. Il aurait fallu prendre un échantillon plus large afin d’avoir plus de résultats. Cependant, il permettrait de donner des idées ou une ligne guide afin d’améliorer la collaboration avec les parents. La recherche a montré que la collaboration ne fonctionne pas s’il manque un des trois pôles. La collaboration n’est pas toujours présentes selon le niveau de réussite de l’élève. Nous remarquons aussi que les enseignants sont plus investis si l’enfant est en phase d’échec. En dernier lieu, la définition des rôles permet de valoriser les acteurs et les aider à se sentir plus investis.

description: We present the first numerical solutions of the causal, stable relativistic Navier-Stokes equations as formulated by Bemfica, Disconzi, Noronha, and Kovtun (BDNK). For this initial investigation we restrict to plane-symmetric configurations of a conformal fluid in Minkowski spacetime. We consider evolution of three classes of initial data: a smooth (initially) stationary concentration of energy, a standard shock tube setup, and a smooth shockwave setup. We compare these solutions to those obtained with the Muller-Israel-Stewart (MIS) formalism, variants of which are the common tools used to model relativistic, viscous fluids. We find that for the two smooth initial data cases, simple finite difference methods are adequate to obtain stable, convergent solutions to the BDNK equations. For low viscosity, the MIS and BDNK evolutions show good agreement. At high viscosity the solutions begin to differ in regions with large gradients, and there the BDNK solutions can (as expected) exhibit violation of the weak energy condition. This behavior is transient, and the solutions evolve toward a hydrodynamic regime in a way reminiscent of an approach to a universal attractor. For the shockwave problem, we give evidence that if a hydrodynamic frame is chosen so that the maximum characteristic speed of the BDNK system is the speed of light (or larger), arbitrarily strong shockwaves are smoothly resolved. Regarding the shock tube problem, it is unclear whether discontinuous initial data is mathematically well-posed for the BDNK system, even in a weak sense. Nevertheless we attempt numerical solution, and then need to treat the perfect fluid terms using high-resolution shock-capturing methods. When such methods can successfully evolve the solution beyond the initial time, subsequent evolution agrees with corresponding MIS solutions, as well as the perfect fluid solution in the limit of zero viscosity.

description: The fully frustrated ladder - a quasi-1D geometrically frustrated spin one half Heisenberg model - is non-integrable with local conserved quantities on rungs of the ladder, inducing the fragmentation of the Hilbert space into sectors composed of singlets and triplets on rungs. We explore the far-from-equilibrium dynamics of this model through the entanglement entropy and out-of-time-ordered correlators (OTOC). The post-quench dynamics of the entanglement entropy is highly anomalous as it shows clear non-damped revivals that emerge from short connected chunks of triplets and whose persistence is therefore a consequence of fragmentation. We find that the maximum value of the entropy follows from a picture where coherences between different fragments co-exist with perfect thermalization within each fragment. This means that the eigenstate thermalization hypothesis holds within all sufficiently large Hilbert space fragments. The OTOC shows short distance oscillations arising from short coupled fragments, which become decoherent at longer distances, and a sub-ballistic spreading and long distance exponential decay stemming from an emergent length scale tied to fragmentation.

Looking Through the Window: Prostitutes and Their Neighbours (Rio de Janeiro, Early Twentieth Century)
Creators: name: Schettini, Cristiana
Publisher: name: Moving the Social
Year: 2015

description: This article analyses some of the debates on the regulation of sex trade in Rio de Janeiro and the enforcement of a particular set of “non-regulationist” policies at the beginning of the First Republic (1889–1930). I argue that against the background of conflicts in local politics and labour relations, “non-regulationist” policies in Rio de Janeiro opened up unexpected possibilities for prostitutes, who reinterpreted the available law in their dealings with neighbors and other workers. The historical process of the abolition of slavery in Brazil, together with the consolidation of an authoritarian republican regime, created the conditions that allowed Rio de Janeiro’s police to enforce a particular policy of surveillance and control of specific groups of prostitutes. This policy resulted in the increasing clustering of prostitutes – particularly those who used to parade themselves in the doors and windows of their own homes – in designated urban spaces. Although this process had a significant impact on the relationship between the groups of prostitutes and other workers and neighbours, it nevertheless failed to dissolve their bonds.

description: As a step towards formulating projective superspace techniques for supergravity theories with eight supercharges, this work is devoted to field theory in five-dimensional N = 1 anti-de Sitter superspace AdS^{5|8} = SU(2,2|1)/SO(4,1) x U(1) which is a maximally symmetric curved background. We develop the differential geometry of AdS^{5|8} and describe its isometries in terms of Killing supervectors. Various off-shell supermultiplets in AdS^{5|8} x S^2 are defined, and supersymmetric actions are constructed both in harmonic and projective superspace approaches. Several families of supersymmetric theories are presented including nonlinear sigma-models, Chern-Simons theories and vector-tensor dynamical systems. Using a suitable coset representative, we make use of the coset construction to develop an explicit realization for one half of the superspace AdS^{5|8} as a trivial fiber bundle with fibers isomorophic to four-dimensional Minkowski superspace.

We find that it is possible to fit the variance of the domain wall entropy to a power function of L. However, the quality of the data distributions are unsatisfactory with large L > 96. Consequently, it is not possible to reliably determine the fractal dimension of the domain walls.

description: We demonstrate theoretically that an off-resonant circularly polarized electromagnetic field can induce a persistent current in carbon nanotubes, which corresponds to electron rotation about the nanotube axis. As a consequence, the nanotubes acquire magnetic moment along the axis, which depends on their crystal structure and can be detected in state-of-the-art measurements. This effect and related phenomena are analyzed within the developed Floquet theory describing the electronic properties of the nanotubes irradiated by the field.

description: We study non-LTE inversions of the Ca II infrared triplet lines as a tool for inferring physical properties of the quiet Sun. The inversion code is successful in recovering the temperature, velocity and longitudinal magnetic flux density in the photosphere and chromosphere, but the height range where the inversions are sensitive is limited, especially in the chromosphere. We present results of inverting spectropolarimetric observations of the lines in a quiet Sun region. We find three distinct ranges in chromospheric temperature: low temperatures in the internetwork, high temperatures in the enhanced magnetic network and intermediate temperatures associated with low magnetic flux regions in the network. The differences between these regions become more pronounced with height as the plasma-$β$ decreases. These inversions support the picture of the chromosphere, especially close to the magnetic network, being highly inhomogeneous both in the vertical and horizontal directions.

In the chiral transition, three collective excitations appear in the quark spectrum.

Interdisciplinary and Emerging Topics: Biomedical Applications; Magnetic Fluids and Separations; New Applications and Other Emerging Topics (Virtual)
Recent in vivo experimental studies using chlorine-based disinfectants have shown new scientific discoveries about their capabilities for sterilizing power [1]–[3] and inhalation safety/toxicity [4], [5]. In this study, we used aqueous chlorine dioxide (aqCD) as a radical pair-forming agent to investigate whether magnetic fields can control a viral membranous autoxidation through differences in the physical properties of biomembranes. A prepared dry thin film was hydrated by vortexing with 2 mL of 50 mM Tris-HCl buffer (pH 7.4) or D2O, according to the previous method [6]. The dispersion (10 mM) was transferred to a Mini-Extrudor (Avanti Polar Lipids, Inc.) to produce artificial biomembranous nanoparticles. Exposure to a static magnetic field of 0.25 T was performed using a pair of commercially availablepermanent magnets (W215 x D138 x H15 mm). Irradiations of the nanoparticles were performed using an original air-cooled UV-LED irradiation system. To begin with, we analyzed the structural and physicochemical properties of an oxidized viral membranes induced by the peroxyl radical generation after photo-induced degradation of aqCD in the biomembrane. We secondary compared the release rates of aqCD with magnetic field effects on the photochemical reactions developing in the model membrane systems. According to the overall results, the aqCD-radical releases with the field effects obtained using a static field of 0.25 T were more extensive than those obtained at geomagnetic fields. Among other thing, we found the possibility that a static magnetic field influences the pair mechanism in the process of membrane peroxidations induced by excited singlet oxygen (1O2), etc. This innovative methodology must be one of the most adaptable techniques, which may be able to evaluate a detailed reaction scheme in many viral outer membranes equipped with possible magnetic controls, and/or analogize the ultrastructural state of molecular nanoenvironments swiftly and easily. Consequently, further detailed studies on the reaction field-dependent radical pair model with inhalation safety in vivo are now under investigation.References: 1) M.

EfficientNetV2: Smaller Models and Faster Training

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: This paper introduces EfficientNetV2, a new family of convolutional networks that have faster training speed and better parameter efficiency than previous models. To develop this family of models, we use a combination of training-aware neural architecture search and scaling, to jointly optimize training speed and parameter efficiency. The models were searched from the search space enriched with new ops such as Fused-MBConv. Our experiments show that EfficientNetV2 models train much faster than state-of-the-art models while being up to 6.8x smaller. Our training can be further sped up by progressively increasing the image size during training, but it often causes a drop in accuracy. To compensate for this accuracy drop, we propose to adaptively adjust regularization (e.g., dropout and data augmentation) as well, such that we can achieve both fast training and good accuracy. With progressive learning, our EfficientNetV2 significantly outperforms previous models on ImageNet and CIFAR/Cars/Flowers datasets. By pretraining on the same ImageNet21k, our EfficientNetV2 achieves 87.3% top-1 accuracy on ImageNet ILSVRC2012, outperforming the recent ViT by 2.0% accuracy while training 5x-11x faster using the same computing resources.

description: A four month qualitative study was conducted to investigate gender and grade similarities and differences in language; spoken, written and other symbols (art), referring to computers and computer programmes, among elementary school students. The subjects were a heterogeneous intact grade one class of twenty-five students and a heterogeneous intact grade six/seven class of twenty-one students from a small, lower socio-economic school in a large urban centre in British Columbia. Data was gathered over a period of four months through individual and group interviews and, from student responses to broad general questions, in the form of art, journal entries and creative writing. The study took place in the classrooms and in the computer laboratory which consisted of fifteen Commodore 64 computers and three printers. Programmes used were LOGO, KIDWRITER and two district developed programmes, EDITOR (word processing) and MUSIC SHOP. From the analysis of the data clear categories emerged. Findings suggest that: (1) students viewed the world of technology as largely a male domain/ (2) students did not view the use of computers as extraordinary but as a normal part of the everyday school experience/ (3) girls were dissatisfied with the limitations of the programmes, desiring those which featured the Arts and stressed creativity/ (4) Grade Six/Seven boys desired programmes with highly competitive, video-game formats in Mathematics and Spelling/ (5) boys realized the potential of the computer to be used to perform aggressive/violent acts/ (6) Grade One girls desired a computer laboratory environment resembling a spring garden/ (7) Grade Six/Seven girls believed they would be doing word processing as a part of their future jobs/ (8) Grade Six/Seven boys viewed word processing as a tool which would enable them to perform their "real" careers more effectively/and (9) Grade One students preferred typing stories on the computer to printing them by hand.

description: The Mn(Bi$_{1-x}$Sb$_x$)$_2$Te$_4$ series is purported to span from antiferromagnetic (AF) topological insulator at x = 0 to a trivial AF insulator at x = 1. Here we report on neutron diffraction and inelastic neutron scattering studies of the magnetic interactions across this series. All compounds measured possess ferromagnetic (FM) triangular layers and we find a crossover from AF to FM interlayer coupling near x = 1 for our samples. The large spin gap at x = 0 closes rapidly and the average FM exchange interactions within the triangular layer increase with Sb substitution. Similar to a previous study of MnBi$_2$Te$_4$, we find severe spectral broadening which increases dramatically across the compositional series. In addition to broadening, we observe an additional sharp magnetic excitation in MnSb$_2$Te$_4$ that may indicate the development of local magnetic modes based on recent reports of antisite disorder between Mn and Sb sublattices. The results suggest that both substitutional and antisite disorder contribute substantially to the magnetism in Mn(Bi$_{1-x}$Sb$_x$)$_2$Te$_4$.

description: A new kinematic and dynamic study of the halo of the giant elliptical galaxy, NGC 5128, is presented. From a spectroscopically confirmed sample of 340 globular clusters and 780 planetary nebulae, the rotation amplitude, rotation axis, velocity dispersion, and the total dynamical mass are determined for the halo of NGC 5128. The globular cluster kinematics were searched for both radial dependence and metallicity dependence by subdividing the globular cluster sample into 158 metal-rich ([Fe/H] > -1.0) and 178 metal-poor ([Fe/H] < -1.0) globular clusters. Our results show the kinematics of the metal-rich and metal-poor subpopulations are quite similar. The kinematics are compared to the planetary nebula population where differences are apparent in the outer regions of the halo. The total mass of NGC 5128 is found using the Tracer Mass estimator (Evans et al. 2003), to determine the mass supported by internal random motions, and the spherical component of the Jeans equation to determine the mass supported by rotation. We find a total mass of (1.0+/-0.2) x 10^(12) Msun from the planetary nebulae data out to a projected radius of 90 kpc and (1.3+/-0.5) x 10^(12) Msun from the globular clusters out to a projected radius of 50 kpc. Lastly, we present a new and homogeneous catalog of known globular clusters in NGC 5128. This catalog combines all previous definitive cluster identifications from radial velocity studies and HST imaging studies, as well as 80 new globular clusters from a study of M.A. Beasley et al. (2007, in preparation).

Οι περιορισμοί του προβλήματος ορίζουν πως η χωρητικότητα των οχημάτων δεν πρέπει να παραβιάζεται από συνολική ζήτηση που καλύπτεται από αυτά, ενώ παράλληλα η επιμέρους ζήτηση κάθε πελάτη να καλύπτεται πλήρως από ένα μόνο όχημα. Τέλος, σε διαφορετικές εκδοχές του προβλήματος, εφαρμόζεται άνω φράγμα στο συνολικό χρόνο της διαδρομής των οχημάτων.

description: The ExoMars mission of the program Aurora (ESA) aims to send a vehicle (Rover) on Mars in 2013. Beyond the technological aspects of the mission, the Rover will also carry scientific instruments for the analysis of Mars subsurface to search traces of past or present life in the Martian soil. The Rover will embark a drilling machine which will give access to samples of sub-surface of Mars to 2 meters depth. This constitutes the great originality of ExoMars, because the Mars sub-surface remains still unknown and seems to be the best place to shelter good conditions to create life. This drilling machine will be guided by a radar system sounder UHF, the WISDOM instrument, which will also make possible to probe the Mars sub-surface to a few meters of depth to detect water and to study the geological structures. We have analytical and numerical electromagnetic models to simulate the behavior of an electromagnetic wave in the Mars sub-surface, but also to simulate the interactions between the wave and the structure of the Rover. The objective of the work which we present consists in the study of the factors able to create disturbances of measurements in order to correct the effects on the measured signal. Initially we present the solution which we retained in order to be able during the same calculation to simulate the displacement of the Rover on several tens of meters. We also present the results relating to the effect of the orientation of the antenna during displacement due to topography of the observation site.

description: We study the extension of the Kechris-Solecki-Todorcevic dichotomy on analytic graphs to dimensions higher than 2. We prove that the extension is possible in any dimension, finite or infinite. The original proof works in the case of the finite dimension. We first prove that the natural extension does not work in the case of the infinite dimension, for the notion of continuous homomorphism used in the original theorem. Then we solve the problem in the case of the infinite dimension. Finally, we prove that the natural extension works in the case of the infinite dimension, but for the notion of Baire-measurable homomorphism.

description: We report the detection of five Jovian mass planets orbiting high metallicity stars. Four of these stars were first observed as part of the N2K program and exhibited low RMS velocity scatter after three consecutive observations. However, follow-up observations over the last three years now reveal the presence of longer period planets with orbital periods ranging from 21 days to a few years. HD 11506 is a G0V star with a planet of \msini = 4.74 \mjup in a 3.85 year orbit. HD 17156 is a G0V star with a 3.12 \mjup planet in a 21.2 day orbit. The eccentricity of this orbit is 0.67, one of the highest known for a planet with a relatively short period. The orbital period for this planet places it in a region of parameter space where relatively few planets have been detected. HD 125612 is a G3V star with a planet of \msini = 3.5 \mjup in a 1.4 year orbit. HD 170469 is a G5IV star with a planet of \msini = 0.67 \mjup in a 3.13 year orbit. HD 231701 is an F8V star with planet of 1.08 \mjup in a 142 day orbit. All of these stars have supersolar metallicity. Three of the five stars were observed photometrically but showed no evidence of brightness variability. A transit search conducted for HD 17156 was negative but covered only 25% of the search space and so is not conclusive.

description: We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the $D$ and $B$ fields blow up near the cloaking surface. We also consider cloaking with and without the SHS (soft-and-hard surface) lining. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of $D$ and $B$ prevented.

Surfaces from Circles

Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: In the search for appropriate discretizations of surface theory it is crucial to preserve such fundamental properties of surfaces as their invariance with respect to transformation groups. We discuss discretizations based on Möbius invariant building blocks such as circles and spheres. Concrete problems considered in these lectures include the Willmore energy as well as conformal and curvature line parametrizations of surfaces. In particular we discuss geometric properties of a recently found discrete Willmore energy. The convergence to the smooth Willmore functional is shown for special refinements of triangulations originating from a curvature line parametrization of a surface. Further we treat special classes of discrete surfaces such as isothermic and minimal. The construction of these surfaces is based on the theory of circle patterns, in particular on their variational description.

Teaching literacy through interaction

Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study is to describe the similarities between adult assistance to children's early language development and teacher assistance to primary children's literacy development. The main problem the study addresses is how child-centered language interaction was used by teachers in an Emergent Literacy program to promote student's skills in reading and writing. The methodology used were field-based, qualitative research techniques to document interaction during reading and writing conferences. The documentation was done through the use of field notes and audio taping during the conferences. The notes and transcriptions were analyzed for the presence of teacher use of framing and formatting. It was also analyzed for the presence of verbal scaffolds, accountability structures and semantically contingent utterances on the part of the teachers. The study concludes that those selected features of adult assistances to children's language development are present in the teacher assistance to children in this program. This may be explained by the teachers' commitment to child-centered, teacher-guided interactions which place children's efforts and sense of meaning at the center of the literacy learning experiences.

description: The capability to model the nonlinear magnetohydrodynamic (MHD) evolution of stellarator plasmas is developed by extending the M3D-$C^1$ code to allow non-axisymmetric domain geometry. We introduce a set of logical coordinates, in which the computational domain is axisymmetric, to utilize the existing finite-element framework of M3D-$C^1$. A $C^1$ coordinate mapping connects the logical domain to the non-axisymmetric physical domain, where we use the M3D-$C^1$ extended MHD models essentially without modifications. We present several numerical verifications on the implementation of this approach, including simulations of the heating, destabilization, and equilibration of stellarator plasmas with strongly anisotropic thermal conductivity, and of the relaxation of stellarator equilibria to integrable and non-integrable magnetic field configurations in realistic geometries.

Movement or debate? How #MeToo is framed differently in English, Spanish and German Twitter discourse

description: This article examines 1,353 tweets on #MeToo in English, Spanish and German from July and August 2019, revealing how #MeToo is most commonly referred to as a “movement” in English and Spanish but as a “debate” in German, a difference that echoes German-language press habits. Based on an analysis of semantic prosody, the study demonstrates that words indicating longevity such as “era” and “times” collocate with #MeToo in English and Spanish, but not in German. This points to a framing of #MeToo as influential and long-term in English and Spanish and as exaggerated and short-term in German. Reflecting this difference, #MeToo is talked about in more negative terms in German tweets compared to English and Spanish, as shown by a qualitative analysis of evaluative author stance. The study adds to existing knowledge of the power of hashtags for feminist social media activism by highlighting the importance of (cross-)linguistic corpus-assisted discourse studies of hashtags on social media, which helps understand the ways in which anti-feminist discourse taps into the channelling of emotions through hashtags to undermine cross-national women’s movements.

description: We propose a novel method for studying the production of anticentauro events in high energy heavy ion collisions utilizing Chebyshev expansion coefficients. These coefficients have proved to be very efficient in investigating the pattern of fluctuations in neutral pion fraction. For the anticentauro like events, the magnitude of first few coefficients is strongly enhanced (~3 times) as compared to those of normal HIJING events. Various characteristics of Chebyshev coefficients are studied in detail and the probability of formation of exotic events is calculated from the simulated events.

Quantum Monte Carlo simulations of bosonic and fermionic impurities in a two-dimensional hard-core boson system

Year: 2007
Subjects: subject: Other Condensed Matter (cond-mat.other)

description: A two-dimensional lattice hard-core boson system with a small fraction of bosonic or fermionic impurity particles is studied. The impurities have the same hopping and interactions as the dominant bosons and their effects are solely due to quantum statistics. Quantum Monte Carlo simulations are carried out in which paths of the dominant boson species are sampled and a summation is performed over all second-species paths compatible with the permutation cycles. Both kinds of impurities reduce modestly and equally the Kosterliz-Thouless superfluid transition temperature. However, the effective impurity interactions are found to be qualitatively different at lower temperatures; fermions are repulsive and further suppress superfluidity at low temperatures.

description: We study the distribution of finite size pseudo-critical points in a one-dimensional random quantum magnet with a quantum phase transition described by an infinite randomness fixed point. Pseudo-critical points are defined in three different ways: the position of the maximum of the average entanglement entropy, the scaling behavior of the surface magnetization, and the energy of a soft mode. All three lead to a log-normal distribution of the pseudo-critical transverse fields, where the width scales as $L^{-1/ν}$ with $ν=2$ and the shift of the average value scales as $L^{-1/ν_{typ}}$ with $ν_{typ}=1$, which we related to the scaling of average and typical quantities in the critical region.
