description: To scale non-parametric extensions of probabilistic topic models such as Latent Dirichlet allocation to larger data sets, practitioners rely increasingly on parallel and distributed systems. In this work, we study data-parallel training for the hierarchical Dirichlet process (HDP) topic model. Based upon a representation of certain conditional distributions within an HDP, we propose a doubly sparse data-parallel sampler for the HDP topic model. This sampler utilizes all available sources of sparsity found in natural language - an important way to make computation efficient. We benchmark our method on a well-known corpus (PubMed) with 8m documents and 768m tokens, using a single multi-core machine in under four days.

 Ce Melanoxus semble bien moins commun que son congénère précédent. Il a d’abord été découvert au Nimba puis, quelques années plus tard, d’autres échantillons ont été trouvés en Côte d’Ivoire, dans la région des savanes de Lamto (C. Girard). En fait, Il n’est pas spécial à l’Afrique occidentale, mais vit aussi dans les forêts du Cameroun où un individu a été récolté il y a quelques années (Ph. Bruneau de Miré). Il se distingue assez facilement par les deux petites taches rougeâtres qui sont situées à la base des élytres et par la ponctuation plus dense de son pronotum.

description: Any two triangulations of a closed surface with the same number of vertices can be transformed into each other by a sequence of regular flips, provided the number of vertices exceeds a number N depending on the surface. Examples show that in general N is bigger than the minimal number of vertices of a triangulation. The existence of N was known, but no estimate. This paper provides an estimate for N that is linear in the Euler characteristic of the surface.

description: Surveys of microbial biodiversity such as the Earth Microbiome Project (EMP) and the Human Microbiome Project (HMP) have revealed robust ecological patterns across different environments. A major goal in ecology is to leverage these patterns to identify the ecological processes shaping microbial ecosystems. One promising approach is to use minimal models that can relate mechanistic assumptions at the microbe scale to community-level patterns. Here, we demonstrate the utility of this approach by showing that the Microbial Consumer Resource Model (MiCRM) -- a minimal model for microbial communities with resource competition, metabolic crossfeeding and stochastic colonization -- can qualitatively reproduce patterns found in survey data including compositional gradients, dissimilarity/overlap correlations, richness/harshness correlations, and nestedness of community composition. By using the MiCRM to generate synthetic data with different environmental and taxonomical structure, we show that large scale patterns in the EMP can be reproduced by considering the energetic cost of surviving in harsh environments and HMP patterns may reflect the importance of environmental filtering in shaping competition. We also show that recently discovered dissimilarity-overlap correlations in the HMP likely arise from communities that share similar environments rather than reflecting universal dynamics. We identify ecologically meaningful changes in parameters that alter or destroy each one of these patterns, suggesting new mechanistic hypotheses for further investigation. These findings highlight the promise of minimal models for microbial ecology.

Protoplanetary Disk Masses from Radiative Transfer Modeling: A Case Study in Taurus

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Measuring the masses of protoplanetary disks is crucial for understanding their planet-forming potential. Typically, dust masses are derived from (sub-)millimeter flux density measurements plus assumptions for the opacity, temperature, and optical depth of the dust. Here we use radiative transfer models to quantify the validity of these assumptions with the aim of improving the accuracy of disk dust mass measurements. We first carry out a controlled exploration of disk parameter space. We find that the disk temperature is a strong function of disk size, while the optical depth depends on both disk size and dust mass. The millimeter-wavelength spectral index can be significantly shallower than the naive expectation due to a combination of optical depth and deviations from the Rayleigh-Jeans regime. We fit radiative transfer models to the spectral energy distributions (SEDs) of 132 disks in the Taurus-Auriga region using a Markov chain Monte Carlo approach. We used all available data to produce the most complete SEDs used in any extant modeling study. We perform the fitting twice: first with unconstrained disk sizes and again imposing the disk size--brightness relation inferred for sources in Taurus. This constraint generally forces the disks to be smaller, warmer, and more optically thick. From both sets of fits, we find disks to be $\sim$1--5 times more massive than when derived using (sub-)millimeter measurements and common assumptions. With the uncertainties derived from our model fitting, the previously measured dust mass--stellar mass correlation is present in our study but only significant at the 2$σ$ level.

description: An exploration of reactions of 1,1′,1″-(benzene-1,3,5-triyltris(methylene))tris(4-carboxypyridinium)-tribromide (H3LBr3) with LnIII salts has led to the formation of three complexes, {[LnL(H2O)2]·3(NO3)·6H2O} (Ln = Eu (1), Gd (2), and Tb (3)). Single-crystal X-ray analyses revealed that these complexes are isomorphous and have 3-D, channel-like structures, in which the carboxylic acids are fully deprotonated with syn–syn μ2-η1:η1 type bridging modes and L ligands in a chair-shaped configuration. Both 1 and 3 showed strong luminescence upon excitation. Magnetic measurements were performed for 2 and 3. The magnetic studies show that very weak antiferromagnetic couplings exist between GdIII and GdIII in 2. Moreover, powder X-ray diffraction, infrared spectroscopy, and elemental analysis were also performed.
Bundled Causal History Interaction

description: Complex system arises as a result of the nonlinear interactions between components. In particular, the evolutionary dynamics of a multivariate system encodes the ways in which different variables interact with each other individually or in groups. One fundamental question that remains unanswered is: how do two non-overlapping multivariate subsets of variables interact to causally determine the outcome of a specific variable? Here we provide an information based approach to address this problem. We delineate the temporal interactions between the bundles in a probabilistic graphical model. The strength of the interactions, captured by partial information decomposition, then exposes complex behavior of dependencies and memory within the system. The proposed approach successfully illustrates complex dependence between cations and anions as determinants of \textit{pH} in an observed stream chemistry system. This example demonstrates the potentially broad applicability of the approach, establishing the foundation to study the interaction between groups of variables in a range of complex systems.

description: Medium modification of jet fragmentation functions and parton energy loss in cold and hot matter are reviewed. The predicted nuclear modification of the jet fragmentation function agrees well with the recent HERMES data with a resultant energy loss dE/dx approximately 0.5 GeV/fm. From the the recent PHENIX data of high p_T pi_0 spectra in central Au+Au collisions at sqrt(s)=130 GeV, one extracts an energy loss for a 10 GeV parton that is equivalent to dE/dx=7.3 GeV/fm in a static medium with the same gluon density as in the initial stage of the collision at tau_0=0.2 fm/c. Constraints on jet quenching by the central rapidity density of charged hadrons is also discussed.

title: Male Muslim Refugee Experiences of English Language Training Programmes and Links to Employment in Australia

subject: Refugees, Australia

description: Since the modern Refugee and Humanitarian Programme began in 1977, around 14,000 refugees have been granted residency in Australia every year, with Muslim communities now representing more than 50 per cent of the intake. Most of these refugees entering Australia speak little, if any, English, have little or no education in their first language, and most do not possess employment skills or qualifications valued in the Australian workplace. The Federal Government thus offers them English language training within the Adult Migrant English Programme (AMEP) and the Skills for Education and Employment (SEE) programme. These programmes aim to provide refugee migrants with enough English proficiency to gain employment in Australia, and to successfully participate socially and economically in Australian society. However, there has been only limited research specifically centred on these Federal English training programmes. In particular, there have been no in-depth studies centred on the opinions of the actual refugee clients attending these programmes. The research in this thesis thus investigates the perspectives of a group of eight male Muslim refugees on the effectiveness of the Federal English Language Training Programmes in facilitating their settlement and employment in Australia. Male Muslim refugees were chosen as participants as they represent a particularly disadvantaged, but under-researched, minority social group in Australian society. A qualitative research design and methodology was adopted for this research, framed within a socio-critical (transformative) research paradigm. Data was collected using in-depth, semi- structured interviews, and then analysed and described using the theoretical framework of Pierre Bourdieu’s conceptual tools of field, capital and habitus. The findings from this research suggest that there may be a number of key problems with the language training programmes. Most of the refugees in the study failed to find consistent employment, and many entered a repetitive cycle of intermittent attendance at the English training programmes. Additionally, many of the participants reached only a basic proficiency in oral English communication, making little or no progress in their literacy acquisition, and thus they were generally unable to complete any vocational qualifications.

description: In the near future galaxy surveys will target Lyman alpha emitting galaxies (LAEs) to unveil the nature of the dark energy. It has been suggested that the observability of LAEs is coupled to the large scale properties of the intergalactic medium. Such coupling could introduce distortions into the observed clustering of LAEs, adding a new potential difficulty to the interpretation of upcoming surveys. We present a model of LAEs that incorporates Lyman-alpha radiative transfer processes in the interstellar and intergalactic medium. The model is implemented in the GALFORM semi-analytic model of galaxy of formation and evolution. We find that the radiative transfer inside galaxies produces selection effects over galaxy properties. In particular, observed LAEs tend to have low metallicities and intermediate star formation rates. At low redshift we find no evidence of a correlation between the spatial distribution of LAEs and the intergalactic medium properties. However, at high redshift the LAEs are linked to the line of sight velocity and density gradient of the intergalactic medium. The strength of the coupling depends on the outflow properties of the galaxies and redshift. This effect modifies the clustering of LAEs on large scales, adding non linear features. In particular, our model predicts modifications to the shape and position of the baryon acoustic oscillation peak. This work highlights the importance of including radiative transfer physics in the cosmological analysis of LAEs.

description: A proof of Poincaré-Birkhoff-Witt theorem is given for a class of generalized Lie algebras closely related to the Gurevich S-Lie algebras. As concrete examples, we construct the positive (negative) parts of the quantized universal enveloping algebras of type A_n and M_{p,q,e}(n,K), which is a non-standard quantum deformation of GL(n). In particular, we get, for both algebras, a unified proof of the Poincaré-Birkhoff-Witt theorem and we show that they are genuine universal enveloping algebras of certain generalized Lie algebras.

Gefühlssprache - Wie Emojis unsere Wortwahl bestimmen: Eine Analyse des digitalen Kommunikationsstils unserer Zeit

description: Seit Unicode 8.0 haben wir sie alle auf der Tastatur unseres mobilen Endgeräts - Emojis. Allgegenwärtig, gerne und häufig genutzt finden sie mit einem sich wandelnden Kommunikationsstils und der sukzessiven Verlagerung unseres Alltags ins Digitale breitflächig Anwendung. Klassischerweise von jungen Leuten in informellen, privaten Kontexten genutzt, findet die ältere Generation ebenso Gefallen an den 3600 kleinen Symbolen und auch Personen des öffentlichen Lebens erfreuen sich mittlerweile des Repertoires tausender Illustrationen. Selbst Politiker scheuen nicht mehr davor zurück, formale Inhalte mit Emojis auszukleiden (forsa Politik- und Sozialforschung GmbH, 2018; Wurst et al., 2023). Durch ihren affektiven Ausdruck unterstreichen Emojis den emotionalen Gehalt einer Nachricht und erleichtern es de Rezipienten häufig, diesen korrekt einzuordnen (Kaye et al., 2016; Logi & Zappavigna, 2021; Shoeb & de Melo, 2020, Escouflaire, 2021; Tossell et al., 2012; Negishi, 2014). Sie haben naheliegende Funktionen.

Was aber zeichnet ihr Verhältnis zur geschriebenen Sprache aus, was ist ire semantische Funktion? Werden Emojis eher Textsprache ergänzend oder Textsprache ersetzend verwendet? Wie steht die Vielfältigkeit von Wörtern im Verhältnis zur Vielfältigkeit von Emojis? Mit meiner Arbeit möchte ich mich nicht auf die Seite konservativer Sprachliebhaber stellen, die bereits seit Jahrzehnten um die Diversität von Sprache fürchten, ihren inhaltlichen und formellen Verfall beklagen und in Emojis möglicherweise den Höhepunkt eines unabdingbaren degenerativen Prozesses sehen. Ich möchte, diesen Gedanken spielerisch aufgreifend, vielmehr das Verhältnis von Emoji-Use und Sprachgebrauch in Hinblick auf unseren emotionalen Ausdruck untersuchen. Denn, Emojis als Pendant zu Mimik und Körpersprache betrachtend, glaube ich, dass sie uns erlauben, manchmal das zu sagen, was dem bewussten Geist entrinnt (vgl. Schooler et al., 1993). Sie stellen ein Mittel dar, wortlos zu kommunizieren. Emojis sind unsere digitale Körpersprache. Greifen wir, um Emotionen Ausdruck zu verleihen also vielleicht eher zu Bildern als zu Worten?

description: The production cross section for pseudo-scalar Higgs bosons at hadron colliders is computed at next-to-next-to-leading order (NNLO) in QCD. The pseudo-scalar Higgs is assumed to couple only to top quarks. The NNLO effects are evaluated using an effective lagrangian where the top quarks are integrated out. The NNLO corrections are similar in size to those found for scalar Higgs boson production.

description: We report on the structure, magnetization, magnetic anisotropy, and domain morphology of ultrathin yttrium iron garnet (YIG)/Pt films with thickness ranging from 3 to 90 nm. We find that the saturation magnetization is close to the bulk value in the thickest films and decreases towards low thickness with a strong reduction below 10 nm. We characterize the magnetic anisotropy by measuring the transverse spin Hall magnetoresistance as a function of applied field. Our results reveal strong easy plane anisotropy fields of the order of 50-100 mT, which add to the demagnetizing field, as well as weaker in-plane uniaxial anisotropy ranging from 10 to 100 $μ$T. The in-plane easy axis direction changes with thickness, but presents also significant fluctuations among samples with the same thickness grown on the same substrate. X-ray photoelectron emission microscopy reveals the formation of zigzag magnetic domains in YIG films thicker than 10 nm, which have dimensions larger than several 100 $μ$m and are separated by achiral Néel-type domain walls. Smaller domains characterized by interspersed elongated features are found in YIG films thinner than 10 nm.

description: This paper explores the topics within psychology of creativity such as past studies on expertise, brain function, and memory, in addition to past models for understanding how those deemed as creative individuals solve problems in novel ways. Within this paper, various older models of creativity are explained, a new definition of creativity is posed, and ultimately, the model presented in the text as the basis for all creativity analyses is the constraint model devised by Patricia D. Stokes. The reader will learn about where creativity has come from, how it had been studied, and why Stokes’ model in particular is the most appropriate to use when studying creativity. Utilizing the structure of a conversational novel, this paper discusses creativity constraints within art (with painters Umberto Boccioni, Jean-Baptiste-Camille Corot, and Frederic Bazille), and constraints within literature (A. S. Byatt, Italo Calvino, Milan Kundera, and Annie Dillard). This model is then applied specifically with the writer Franz Kafka as a supplemental exploration of creative constraints in literature.

description: We derive an exact renormalization group recursion relation for the Loschmidt amplitude of the quantum $Q$-state clock model and the quantum $Q$-state Potts model in one dimension. The renormalization group flow is discussed in detail. The fixed-points of the renormalization group flow are found to be complex in general. These fixed-points control the dynamical phases of the two models, giving rise to non-analyticities in its Loschmidt rate function, for both the pure and the disordered system. For the quench protocols studied, dynamical quantum phase transitions are found to occur in the clock model for all $Q$s considered, while in the Potts model, they only occur when $Q$ < 4.

description: Biogenic collagen membranes (BCM) have been widely used in guided bone regeneration (GBR) owing to their biodegradability during tissue integration. However, their relatively high degradation rate and lack of pro-osteogenic properties limit their clinical outcomes. It is of great importance to endow BCM with tailored degradation as well as pro-osteogenic properties. In this study, a fluoride-modified polymer-induced liquid precursor (PILP) based biomineralization strategy was used to convert the collagen membrane from an organic phase to an apatite-based inorganic phase, thus achieving enhanced anti-degradation performance as well as osteogenesis. As a result, three phases of collagen membranes were prepared. The original BCM in the organic phase induced the mildest inflammatory response and was mostly degraded after 4 weeks. The organic-inorganic mixture phase of the collagen membrane evoked a prominent inflammatory response owing to the fluoride-containing amorphous calcium phosphate (F-ACP) nanoparticles, resulting in active angiogenesis and fibrous encapsulation, whereas the inorganic phase induced a mild inflammatory response and degraded the least owing to the transition of F-ACP particles into calcium phosphate with high crystallinity. Effective control of ACP is key to building novel apatite-based barrier membranes. The current results may pave the way for the development of advanced apatite-based membranes with enhanced barrier performances.

Although diagnosis is made based upon the occurrence of positive and negative symptoms (First, Spitzer, Gibbon & Williams, 1995), it is the cognitive symptoms that are most strongly associated with functional outcome (Green, 1996 ). Cognitive control, including the ability to appropriately update relevant information and resist interference from irrelevant information, is critical for flexible and adaptive goal-directed behavior, and is among the most frequently noted of the cognitive symptoms in schizoprenia (Barch, 2005; Barch & Smith, 2008). Despite this, deficits in cognitive control are unaffected by medications used to treat the clinical symptoms of the disorder (Greene et al, 2008).  Understanding both the behavioral and the neural mechanisms that comprise this deficit is thus of paramount importance.  Although deficits in cognitive control in schizoprenia have been extensively studied, a number of questions still remain.  Here, I ask two main questions: First, is cognitive control impaired globally, or are only certain aspects of cognitive control impaired in schizophrenia?  I found that that there are (at least) two different selection mechanisms, and that people with schizophrenia are impaired in only one of these: dysregulation in left posterior ventrolateral prefrontal cortex correlates with impaired behavioral performance on a working memory task, suggesting that deficits in inhibiting irrelevant information from working memory is the crux of the deficit.  Second, I asked whether the nature of the information affects cognitive control.  I found that people with schizophrenia are able to deploy cognitive control processes more effectively than healthy controls in cases in which salient, emotional information competes with active cognitive goals, suggesting specific underlying deficits in emotional processing.

description: Chains of magnetic impurities placed on a superconducting substrate and forming helical spin order provide a promising venue for realizing a topological superconducting phase. An effective tight-binding description of such helical Shiba chains involves long-range (power-law) hopping and pairing amplitudes which induce an unconventional topological critical point. At the critical point, we find exponentially localized Majorana bound states with a short localization length unrelated to a topological gap. Away from the critical point, this exponential decay develops a power-law tail. Our analytical results have encouraging implications for experiment.

description: We consider the focusing cubic wave equation in the energy supercritical case, i.e., in dimensions $d \geq 5$. For this model an explicit nontrivial self-similar blowup solution was recently found by the first and third author in \cite{GlogicSchoerkhuber}. Furthermore, the solution is proven to be co-dimension one stable in $d=7$. In this paper, we study the equation from a numerical point of view. For $d=5$ and $d=7$ in the radial case, we provide evidence that this solution is at the threshold between generic ODE blowup and dispersion. In addition, we investigate the spectral problem that underlies the stability analysis and compute the spectrum in general supercritical dimensions.

description: In this note, we propose that an object moving with proper constant acceleration, i.e., a Rindler observer experiences a sublimation (or evaporation) process. In this first proposal, we do not consider the backreaction due to the sublimation. We focus on charged matter particles for the discussion, but for simplicity, we present the quantization of the neutrally charged massive scalar field in Rindler space. The amplitude from the Minkowski observer perspective of detection of matter particles that have been emitted by a Rindler observer, or accelerated detector, is computed in a new fashion. We make a comparison between the Rindler observer sublimation and the black hole evaporation. We present three variants of a new experimental setup, and we show that in two of them, the Minkowski amplitude of detection of matter particles corresponds to that of a thermal process. There is one, however, where deviations from thermality can be found. It is numerically explored.

description: Der Beitrag gibt – unter Rückgriff auf eigene Forschungen zum Thema – einen Überblick über Möglichkeiten und Grenzen des für die Umweltstrategie wichtig gewordenen Konzepts der „ökologische Modernisierung“. Der Begriff beschreibt in seiner ursprünglichen Fassung das große Segment möglicher Umweltverbesserungen, die durch technischen Fortschritt jenseits von End-of- pipe-Ansätzen und diesseits von weitergehenden strukturellen Lösungen zu erzielen sind. Dabei kommt dem Mechanismus der Innovationsdiffusion eine spezielle Bedeutung zu, zumal dann, wenn es um die Entwicklung einer globalen Strategie der ökologischen Modernisierung geht. Von besonderem Interesse ist das Wechselspiel von Politik und Technik in diesem Prozess. In aller Regel weisen technisch lösbare Umweltprobleme umweltpolitisch einen geringeren Schwierigkeitsgrad auf als solche, die strukturelle Eingriffe erfordern. Der Begriff der ökologischen Modernisierung könnte – im Gegensatz zu weiteren Fassungen - dieses ökonomischtechnische Potenzial akzentuieren und so die Abgrenzung des schwierigeren Pensums eines ökologischen Struktur- und Lebensstilwandels erleichtern.
description: The article gives an analysis of the possibilities and limits of the concept of ecological modernisation. The concept was used already in the early 1980s to describe the common field of ecology and economy. The focus was on technological progress reducing the environmental impact of production and consumption. Hajer and other authors had a broader definition of the concept. But it could make sense to differentiate technical non-technical solutions (the latter being less compatible with the economic system). The limits to eco-modernisation strategies and the need for „structural“ solutions could possibly better be demonstrated by the earlier concept. A policy for ecological modernisation may be defined as the sum of government actions aimed to stimulate environmental innovations and their diffusion. Higher eco- efficiency - instead of end-of-pipe measures - is its main objective. But innovation is a highly difficult task, especially for governments. No simple „instrumentalistic“ solution is available. Therefore, a more complex policy pattern will be necessary. A more global policy approach would be the stimulation of „green“ lead markets. As a rule a complex interplay between political and technical innovation and diffusion can be observed.
