Beschäftigungspolitik in Österreich vor dem Hintergrund einer Europäischen Beschäftigungspolitik
Creators: name: Biffl, Gudrun
Publisher: name: Österreichische Zeitschrift für Politikwissenschaft
Year: 2015

description: Die Einbindung Österreichs in die EU hat eine Verringerung des Entscheidungsspielraums in der Beschäftigungspolitik zur Folge. Die Beschäftigungspolitik muss einem vorgegebenen Muster folgen, in das die traditionellen ebenso wie die innovativen politischen Maßnahmen eingebunden werden. Das bedeutet, dass eine Förderstruktur importiert wird, die mit der österreichischen nicht kongruent ist. Um diese Diskrepanzen abzubauen, liegt ein Schwerpunkt des Nationalen Aktionsplans (NAP) in der Anpassung der österreichischen institutionellen Rahmenbedingungen an EU-Strukturen. Der NAP sieht keine substanzielle Ausweitung der Budgetausgaben zur Förderung der Beschäftigung vor. Der Schwerpunkt der zusätzlichen Ausgaben liegt in der aktiven Arbeitsmarktpolitik, die vom Arbeitsmarktservice (AMS) umgesetzt wird.

description: Growth-fragmentation processes describe systems of particles in which each particle may grow larger or smaller, and divide into smaller ones as time proceeds. Unlike previous studies, which have focused mainly on the self-similar case, we introduce a new type of growth-fragmentation which is closely related to Lévy driven Ornstein-Uhlenbeck type processes. Our model can be viewed as a generalization of compensated fragmentation processes introduced by Bertoin, or the stochastic counterpart of a family of growth-fragmentation equations. We establish a convergence criterion for a sequence of such growth-fragmentations. We also prove that, under certain conditions, this system fulfills a law of large numbers.

„Dritter Weg” oder „Eurokeynesianismus”? Zur Entwicklung der Europäischen Beschäftigungspolitik seit dem Amsterdamer Vertrag
Creators: name: Aust, Andreas
Publisher: name: Österreichische Zeitschrift für Politikwissenschaft
Year: 2015

description: Der Beitrag untersucht die Entwicklung der Europäischen Beschäftigungspolitik seit ihrer Verankerung in dem Amsterdamer Vertrag (beschäftigungspolitische Leitlinien, Beschäftigungspakt und Lissabonner Sondergipfel). Der Autor geht dabei von zwei konkurrierenden Konzepten – Dritter Weg und Eurokeynesianismus – aus, skizziert diese kurz und geht dann der Frage nach, ob, von wem befördert und wie sich diese Konzepte in der Europäischen Beschäftigungspolitik niederschlagen. Es lässt sich zeigen, dass die beschäftigungspolitischen Leitlinien den Grundgedanken des Dritten Weges folgen. Strategiekonzepte für einen Eurokeynesianismus standen während des Verhandlungsprozesses zum Europäischen Beschäftigungspakt ganz oben auf der Agenda, konnten sich allerdings nur in engen Grenzen durchsetzen. Das Ergebnis erschöpft sich in der Verabredung eines weitgehend unverbindlichen makroökonomischen Dialogs zwischen den wichtigsten wirtschaftspolitischen Akteuren auf der europäischen Ebene. Von einem makroökonomischen Kurswechsel, wie er von dieser Strategievariante vor allem für die Geldpolitik gefordert wurde, ist zumindest bislang nichts zu spüren.

description: Post-translational modification (PTM) of proteins plays a key role in signal transduction, and hence significant effort has gone toward understanding how PTM networks process information. This involves, on the theory side, analyzing the dynamical systems arising from such networks. Which networks are, for instance, bistable? Which networks admit sustained oscillations? Which parameter values enable such behaviors? In this Perspective, we highlight recent progress in this area and point out some important future directions. Along the way, we summarize several techniques for analyzing general networks, such as eliminating variables to obtain steady-state parametrizations, and harnessing results on how incorporating intermediates affects dynamics.

description: Kolmogorov-Sinai entropy is an invariant of measure-preserving actions of the group of integers that is central to classification theory. There are two recently developed invariants, sofic entropy and Rokhlin entropy, that generalize classical entropy to actions of countable groups. These new theories have counterintuitive properties such as factor maps that increase entropy. This survey article focusses on examples, many of which have not appeared before, that highlight the differences and similarities with classical theory.

description: Recent robotic manipulation competitions have highlighted that sophisticated robots still struggle to achieve fast and reliable perception of task-relevant objects in complex, realistic scenarios. To improve these systems' perceptive speed and robustness, we present SegICP, a novel integrated solution to object recognition and pose estimation. SegICP couples convolutional neural networks and multi-hypothesis point cloud registration to achieve both robust pixel-wise semantic segmentation as well as accurate and real-time 6-DOF pose estimation for relevant objects. Our architecture achieves 1cm position error and <5^\circ$ angle error in real time without an initial seed. We evaluate and benchmark SegICP against an annotated dataset generated by motion capture.

description: There are many different ways that the exponents of Weyl groups of irreducible root systems have been defined and put into practice. One of the most classical and algebraic definitions of the exponents is related to the eigenvalues of Coxeter elements. While the coefficients of the height root when expressed as a linear combination of simple roots are combinatorial objects in nature, there are several results asserting relations between these exponents and coefficients. This study was conducted to give a uniform and fairly elementary proof of the fact that the second smallest exponent of the Weyl group is one or two plus the largest coefficient of the highest root of the root system depending upon a simple condition on the root lengths. As a consequence, we obtain a necessary and sufficient condition for a root system to be of type $G_2$ in terms of these numbers.

Consistent structure estimation of exponential-family random graph models with block structure
Creators: name: Schweinberger, Michael
Publisher: name: arXiv
Year: 2017
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: We consider the challenging problem of statistical inference for exponential-family random graph models based on a single observation of a random graph with complex dependence. To facilitate statistical inference, we consider random graphs with additional structure in the form of block structure. We have shown elsewhere that when the block structure is known, it facilitates consistency results for $M$-estimators of canonical and curved exponential-family random graph models with complex dependence, such as transitivity. In practice, the block structure is known in some applications (e.g., multilevel networks), but is unknown in others. When the block structure is unknown, the first and foremost question is whether it can be recovered with high probability based on a single observation of a random graph with complex dependence. The main consistency results of the paper show that it is possible to do so under weak dependence and smoothness conditions. These results confirm that exponential-family random graph models with block structure constitute a promising direction of statistical network analysis.

description: We consider the so-called frog model with random initial configurations. The dynamics of this model is described as follows: Some particles are randomly assigned on any site of the multidimensional cubic lattice. Initially, only particles at the origin are active and these independently perform simple random walks. The other particles are sleeping and do not move at first. When sleeping particles are hit by an active particle, they become active and start moving in a similar fashion. The aim of this paper is to derive large deviation and concentration bounds for the first passage time at which an active particle reaches a target site.

description: In this paper we prove a new recurrence relation on the van der Waerden numbers, $w(r,k)$. In particular, if $p$ is a prime and $p\leq k$ then $w(r, k) > p \cdot \left(w\left(r - \left\lceil \frac{r}{p}\right\rceil, k\right) -1\right)$. This recurrence gives the lower bound $w(r, p+1) > p^{r-1}2^p$ when $r \leq p$, which generalizes Berlekamp's theorem on 2-colorings, and gives the best known bound for a large interval of $r$. The recurrence can also be used to construct explicit valid colorings, and it improves known lower bounds on small van der Waerden numbers.

The role of DEL1 in chondrocyte expansion and mechanotransduction: an investigative study
Creators: name: Qusous, Ala
Publisher: name: University of Westminster
Year: 2009

description: Matrix-induced autologous chondrocyte implantation offers a potential cure for joint disease and is currently challenged by loss of differentiated phenotype upon culture. To investigate the mechanism of dedifferentiation, chondrocytes were cultured at low density (1x104cell/cm2) and subcultured on days 9 (P1), 14 (P2) and 21 (P3). A loss of a differentiated phenotype was observed in P1 with a reduction in sphericity from 0.72±0.02 to 0.52±0.03. Changes in cellular dimensions in response to 2D culture were additionally recorded with an increase and decrease in cell length and depth, respectively, yielding an increase in cell volume from 474.72±32.08 to 725.20±35.55μm3. Furthermore, the effect of 2D culture-induced dedifferentiation on mechanotransduction was investigated in response to a hyperosmotic challenge whereby regulatory volume increase (RVI) was only observed in 2D cultured chondrocytes with linear volume recovery rates in P1 and biphasic RVI in P2 and P3. Similarly, a REV5901-induced intracellular calcium rise via PLCβ and PKC was shown to be sensitive to extracellular sodium ([Na+]e) in freshly isolated and Gd3+ in 2D cultured chondrocytes. A 2.70±0.63-fold increase in type I collagen (col1) expression was observed in P1 chondrocytes, whereas a 1.58±0.43-fold increase in type II collagen (col2) was followed by a decline to baseline levels upon further culture. A transient rise in the chondrocytic transcription factor Sox9 and Developmental Endothelial Locus 1 (DEL1) was observed in P1 chondrocytes, suggesting the existence of a third phenotype termed ‘mesodifferentiated*’ and a potential role for DEL1 in chondrocyte dedifferentiation. DEL1 knockdown by RNA interference (RNAi) promoted a differentiated phenotype as characterised by a decrease in cell volume, reduced col1 expression, inhibition of RVI and elevated sensitivity to [Na+]e. DEL1 knockdown was shown to inhibit P1-associated Akt phosphorylation and the expression of the dedifferentiation transcription factor Twist, additionally reduced in the presence of R-Etodolac. The induction of Sox9 expression using Bone Morphogenetic Protein 2 and Twist knockdown using RNAi enhanced the expression of DEL1, suggesting DEL1 regulation of dedifferentiation by a feedback signal previously unreported.

description: Pulses of extreme ultraviolet (XUV) light, with wavelengths between 10 and 100$\,$nm, can be used to image and excite ultra-fast phenomena such as the motion of atomic electrons. Here we show that the illumination of plasma with near-critical electron density may be used as a source of relativistically intense XUV radiation, providing the means for novel XUV-pump--XUV-probe experiments in the non-linear regime. We describe how the optimal regime may be reached by tailoring the laser-target interaction parameters and by the presence of preplasma. Our results indicate that currently available laser facilities are capable of producing XUV pulses with duration $\sim 10~\text{fs}$, brilliance in excess of $10^{23}$ photons/s/mm$^2$/mrad$^2$ (0.1% bandwidth) and intensity $Iλ^2 \gtrsim 10^{19}~\text{W}\text{cm}^{-2}μ\text{m}^2$.

description: Goals are results of pin-point shots and it is a pivotal decision in soccer when, how and where to shoot. The main contribution of this study is two-fold. At first, after showing that there exists high spatial correlation in the data of shots across games, we introduce a spatial process in the error structure to model the probability of conversion from a shot depending on positional and situational covariates. The model is developed using a full Bayesian framework. Secondly, based on the proposed model, we define two new measures that can appropriately quantify the impact of an individual in soccer, by evaluating the positioning senses and shooting abilities of the players. As a practical application, the method is implemented on Major League Soccer data from 2016/17 season.

title: Riots als Transformationsstufe von Klassenkampf
Creators: name: Reisinger, David
Year: 2023

description: Mit dem Ziel einer marxistischen Theorie zu Riots, wird in dieser Arbeit zwischen dem marxschen Werk in seinen unterschiedlichen Lebensphasen und dem Marxismus in seinen unterschiedlichen theoretischen Varianten differenziert. Hierfür wird eine Unterscheidung zwischen dem Post-Marxismus Alain Badious oder Antonio Negris und dem Neomarxismus Joshua Clovers entwickelt. Während der Post-Marxismus in seiner Riot-Theorie vor einem Subjektivismus/Voluntarismus-Problem steht, kann der Neomarxismus die deterministisch/geschichtstheologische Ausrichtung des marxistischen/marxschen Projekts nicht überwinden, beziehungsweise scheitert an der empirischen Bestätigung. Für einen neuen Blickwinkel auf Riots wird die marxsche Begriffsentwicklung des Lumpenproletariats als historisches Überbleibsel zur Überfluss-Bevölkerung als sich immanent aus der Kapitalakkumulation entwickelnd dargestellt. Anknüpfend an Clovers Perspektive wird gezeigt, dass die Überfluss-Bevölkerung aus dem Kapitalverhältnis herausfällt und darum kein Teil der Arbeiter_innenklasse ist. Aus dieser Perspektive sind Riots Klassenkampf der sich zur Multitude entwickelnden Überfluss-Bevölkerung. Diese Form des Klassenkampfes unterscheidet sich vom Streik und sozialer Bewegung durch das nicht-Hervorbringen von Kollektivität und der ökonomietheoretischen Basis im Waren-, nicht Arbeitspreis. Durch das nicht-hervorbringen von Kollektivität, welches anknüpfend an Asef Bayats Kategorie des „Non-Movements“ interpretiert wird, reflektieren Riots das Scheitern der „Kommunistischen Hypothese“ im 20. Jahrhundert.
description: With the aim of a Marxian theory on Riots, a differentiation is made between the Marxian work in its different phases of life and Marxism in its different theoretical variants. For this purpose, a distinction is developed between Alain Badiou's or Antonio Negri's post-Marxism and Joshua Clover's neo-Marxism. While post-Marxism faces a subjectivism/voluntarism problem in its riot theory, neo-Marxism cannot overcome the determinist/historical-teological orientation of Marx's work, respectively fails to provide empirical confirmation. For a new perspective on Riots, the Marxian conceptual development of the lumpenproletariat as a historical remnant to the surplus population is presented as developing immanently from capital accumulation. Following Clovers perspective, it is shown that the surplus population falls outside the capital relation and is therefore not part of the working class. From this perspective, riots are class struggle of the surplus population developing into the multitude. This form of class struggle differs from the strike and social movement by the non-emergence of collectivity and the economic theoretical basis in the commodity not labor price. Through the non-production of collectivity, which is interpreted following Asef Bayat's category of "non-movement", riots reflect the failure of the "communist hypothesis" in the 20th century.

description: We study the long wavelength excitations in rotating QCD fluid in presence of an external magnetic field at finite vector and axial charge densities. We consider the fluctuations of vector and axial charge currents coupled to energy and momentum fluctuations and compute the $SO(3)$ covariant dispersion relations of the six corresponding hydrodynamic modes. Among them, there are always two scalar Chiral Magnetic-Vortical-Heat (CMVH) waves; In the absence of magnetic field (vorticity) these waves reduce to CVH (CMH) waves. While CMVH waves are the mixed of CMH and CVH waves, they have generally different velocities compared to the sum of velocities of the latter waves. The other four modes, which are made out of scalar-vector fluctuations, are mixed Sound-Alfvén waves. We show that in the direction parallel to both magnetic field and vorticity, these four modes are the two ordinary sound modes together with two Chiral Alfvén waves (CAW).

Neo-orientalism? A critical appraisal of changing Western perspectives: Bernard Lewis, John Esposito and Gilles Kepel
Creators: name: Samiei, Mohammad
Publisher: name: University of Westminster
Year: 2009

description: In order to justify and naturalise domination and exploitation of ‘others,’ some ideologies that theorise ‘they are less human’ have been invented and employed throughout history. Among these ideologies is the ‘West‐and‐Islam’ dualism, which has been comprehensively and critically studied by Edward Said in Orientalism. Since Orientalism was published in 1978, however, the world seems to have become much more interdependent and political interrelations between the West and Islam have changed dramatically. Consequently this dualism, though more or less in place, has been influenced by escalating waves of globalisation and redistributed and reshaped in a different form. To critically appraise this dualism in this new era, three prominent contemporary Western Islamologists, Bernard Lewis, John Esposito and Gilles Kepel, have been selected and different aspects of their perspectives, their methodologies, their views on Islam and modernity, their political propositions and Islamic belief and law in their vision, are closely compared and critically examined. These three scholars are used to describe parts of the fabric of what I call neo‐Orientalism; they are exemplars suggesting the existence of a larger whole. This dissertation aims to present the genealogy of some lingering traces of the West‐and‐Islam dualism in order to know how they were originated and how they can be replaced by an egalitarian perspective. This is particularly important in this new interdependent world, where we are very close to each other and any crisis anywhere can affect human beings everywhere. This thesis also aims to criticise the often unquestioned assumptions of Western works on Islam and to show through a comparative examination that there can be very different routes with healthier outcomes to look at other cultures. In addition to methods used by Said and to avoid his shortcomings, this research is informed by a Popperian methodology, relying on his theory of the growth of knowledge, his situational analysis and his views on framework and ideology. In conclusion, this thesis suggests that if the West‐and‐Islam dualism is considered as a spectrum of views on Islam, Lewis is the most dualist, perfectly following all principles of dualism, Esposito is the least, and Kepel is (so to say) in between. Moreover, some promising changes in neo‐Orientalism as well as some additional dualistic tendencies that can define neo‐Orientalism are found in this new era. To portray a better future for our interdependent world some new approaches to identity, global ethics and global civil society are suggested. Eradicating the roots of Orientalism and Occidentalism alike and accepting, protecting and even promoting diversity are first steps towards countering devastating threats that endanger humankind as a whole.

description: Mott insulators are commonly pictured with electrons localized on lattice sites. Their low-energy degrees of freedom involve spins only. Here we observe emerging charge degrees of freedom in a molecule-based Mott insulator $κ$-(BEDT-TTF)$_2$Hg(SCN)$_2$Br, resulting in a quantum dipole liquid state. Electrons localized on molecular dimer lattice sites form electric dipoles that do not order at low temperatures and fluctuate with frequency detected experimentally in our Raman spectroscopy experiments. The heat capacity and Raman scattering response are consistent with a scenario where the composite spin and electric dipole degrees of freedom remain fluctuating down to the lowest measured temperatures.
Generating variety and insight from 4D networked relationships

Year: 2022

description: This note collates three abstracts of papers that explore approaches to develop variety and insight arising by combining manual, semi-manual and automated analysis and transformations of network representations that conform to 4-dimensional (4D) modelling principles. We present a unified approach that can be used to model a wide range of situations and scenarios, including influence graphs (IGs), signalling & messaging, financial transactions, historic networks (e.g. provenance, family trees, audit information), plans and procedures, and legal rights on assets (e.g. for IP licensing). We build on a unified set of formal entities that can be applied across broad classes of network representations that conform to 4-dimensional modelling principles. We describe a range of semi-automated network transformations and analysis approaches, and we illustrate automating the discovery of emergent properties in such networks.

description: We prove a well-posedness result for stochastic Allen-Cahn type equations in a bounded domain coupled with generic boundary conditions. The (nonlinear) flux at the boundary aims at describing the interactions with the hard walls and is motivated by some recent literature in physics. The singular character of the drift part allows for a large class of maximal monotone operators, generalizing the usual double-well potentials. One of the main novelties of the paper is the absence of any growth condition on the drift term of the evolution, neither on the domain nor on the boundary. A well-posedness result for variational solutions of the system is presented using a priori estimates as well as monotonicity and compactness techniques. A vanishing viscosity argument for the dynamic on the boundary is also presented.

Flux Accretion and Coronal Mass Ejection Dynamics

Year: 2017
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Coronal mass ejections (CMEs) are the primary drivers of severe space weather disturbances in the heliosphere. Models of CME dynamics have been proposed that do not fully include the effects of magnetic reconnection on the forces driving the ejection. Both observations and numerical modeling, however, suggest that reconnection likely plays a major role in most, if not all, fast CMEs. Here, we theoretically investigate the accretion of magnetic flux onto a rising ejection by reconnection involving the ejection's background field. This reconnection alters the magnetic structure of the ejection and its environment, thereby modifying the forces acting upon the ejection, generically increasing its upward acceleration. The modified forces, in turn, can more strongly drive the reconnection. This feedback process acts, effectively, as an instability, which we refer to as a reconnective instability. Our analysis implies that CME models that neglect the effects of reconnection cannot accurately describe observed CME dynamics. Our ultimate aim is to understand changes in CME acceleration in terms of observable properties of magnetic reconnection, such as the amount of reconnected flux. This flux can be estimated from observations of flare ribbons and photospheric magnetic fields.

Dependence of the propagators on the sampling of Gribov copies inside the first Gribov region of Landau gauge

description: Beyond perturbation theory the number of gauge copies drastically increases due to the Gribov-Singer ambiguity. Any way of treating them defines, in principle, a new, non-perturbative gauge, and the gauge-dependent correlation functions can vary between them. Herein various such gauges will be constructed as completions of the Landau gauge inside the first Gribov region. The dependence of the propagators and the running coupling on these gauges will be studied for SU(2) Yang-Mills theory in two, three, and four dimensions using lattice gauge theory, and for a wide range of lattice parameters. While the gluon propagator is rather insensitive to the choice, the ghost propagator and the running coupling show a stronger dependence. It is also found that the influence of lattice artifacts is larger than in minimal Landau gauge.

In our study, we also take into account the magnetohydrodynamic turbulence effects in dense quark matter. We derive the kinetic equations for the spectra of the magnetic helicity density and the magnetic energy density as well as for the chiral imbalances. On the basis of the numerical solution of these equations, we find that turbulence effects are important for the behavior of small scale magnetic fields. It is revealed that, under certain initial conditions, these magnetic fields behave similarly to the electromagnetic flashes of some magnetars. We suggest that fluctuations of magnetic fields, described in frames of our model, which are created in the central regions of a magnetized compact star, can initiate magnetar bursts.

title: Flächenstrukturen aus berührenden Kugeln
Creators: name: Aparicio Garrido, Samuel
Year: 2024

description: Diese Arbeit beschäftigt sich mit Strukturen aus berührenden Kugeln. Solche Strukturen können mithilfe von Polygonnetzen dargestellt werden. Klassische Beispiele sind reguläre oder platonische und halb reguläre oder archimedische Polyeder. Eine weitere Klasse wären die Johnson Körper. Allgemeinere Strukturen können mithilfe von bestimmten Dreiecksnetzen, wie die Lobel Netze oder Kreispackungsnetze, oder Vierecksnetze, wie die Rhombennetze, modelliert werden. Rhombennetze haben einen engen Zusammenhang mit der diskreten Differentialgeometrie. Man kann Kugelpackungsnetze mithilfe der numerischen Optimierung approximieren. Die Lie Sphären Geometrie bietet ein Werkzeug, um bestimmte Strukturen aus orientierten und berührenden Sphären zu untersuchen. In dieser Geometrie werden Sphären als fünfdimensionale Punkten auf einer projektiven Quadrik (der Lie Quadrik) identifiziert. Ob sich zwei Kugeln orientiert berühren, kann mithilfe der durch die Lie Quadrik induzierten Bilinearform bestimmt werden. Von besonderem Interesse sind die Lie Sphären Transformationen, die die orientierte Berührung erhalten und sphärentreu sind.

Addressing Justice Concerns in Coastal Resilience Strategies: a Literature Review
Creators: name: Marcatelli, Michela

Publisher: name: Zenodo
Year: 2024

description: As part of our commitment to advancing environmental justice for coastal communities, the Decade Collaborative Centre for Coastal Resilience has examined the complexities of enhancing resilience in coastal regions while avoiding the reinforcement of existing inequalities. How do power dynamics intersect with the concept of resilience in the current literature, and who benefits and who bears the brunt of coastal transformations?

Drawing on this review, the DCC-CR has delved deeper into the major issues that define coastal justice as seen from Latin America, Africa, and Asia. The focus on the Global South aligns with the Centre's commitment to broaden the geographic representation in and impact of the Ocean Decade. This close reading of the literature brings attention to two pivotal dimensions for interpreting and framing coastal injustices: climate change and resource extraction. By scrutinizing adaptation strategies within coastal cities and their repercussions on vulnerable populations, the literature emphasizes the imperative for an equitable distribution of adaptation infrastructure. Moreover, the examination of the interplay between resource extraction and justice has emerged as a prominent theme, as seen in the analysis of conflicts arising from competing coastal uses, notably impacting small-scale fishers and coastal harvesters. Lastly, our analysis spotlights research endeavors dedicated to unraveling power imbalances in decision-making processes, advocating for a more inclusive approach that acknowledges local knowledge and institutions.

description: High-luminosity modern accelerators, like the Relativistic Heavy Ion Collider (RHIC) at BNL and Large Hadron Collider (LHC) at CERN, inherently have event pile-up scenarios which significantly contribute to physics events as a background. While state-of-the-art tracking algorithms and detector concepts take care of these event pile-up scenarios, several offline analytical techniques are used to remove such events from the physics analysis. It is still difficult to identify the remaining pile-up events in an event sample for physics analysis. Since the fraction of these events is significantly small, it may not be as serious of an issue for other analysis as it would be for an event-by-event analysis. Particularly, when the characteristics of the multiplicity distribution are observable, one needs to be very careful. In the present work, we demonstrate how a small fraction of residual pile-up events can change the moments and their ratios of an event-by-event net-proton multiplicity distribution, which are sensitive to the dynamical fluctuations due to the QCD critical point. For this study we assume that the individual event-by-event proton and antiproton multiplicity distributions follow Poisson, negative binomial or binomial distributions. We observe a significant effect in cumulants and their ratios of net-proton multiplicity distributions due to pile-up events, particularly at lower energies. It might be crucial to estimate the fraction of pile-up events in the data sample while interpreting the experimental observable for the critical point.

description: We begin an investigation into the behavior of Bowditch and Gromov boundaries under the operation of Dehn filling. In particular we show many Dehn fillings of a toral relatively hyperbolic group with 2-sphere boundary are hyperbolic with 2-sphere boundary. As an application, we show that the Cannon conjecture implies a relatively hyperbolic version of the Cannon conjecture.

title: Das Theater der Dämonen
Creators: name: Schömann, Paul Leon
Year: 2023

description: In welchem Zusammenhang stehen die Dämonen mit dem Theater? Gibt es diesen Zusammenhang überhaupt? Drei dämonologische Fallbeispiele sollen zeigen: ja, es gibt ihn. Die Dämonen brillieren mit Maskerade in theatralen Täuschungsmanövern bei Augustin (354–430 n. Chr.). Sie verzaubern durch ein Puppenspiel die Lektüre bei Cervantes (1547–1616). Und ihr Theater expliziert das literarische Schaffensprojekt eines Flaubert (1821–1880). Die Dämonen stehen mit diesen Autoren durch drei Epochen hindurch in einem Zusammenhang zu dem Theater, der sich in epistemologischen, ethischen und rezeptions-ästhetischen Perspektiven philosophisch eingrenzen lässt.

description: We introduce the Lomonosov suite of high-resolution N-body cosmological simulations covering a full box of size 32 $h^{-1}$ Mpc with low-mass resolution particles ($2\times10^7$ $h^{-1}\,M_\odot$) and three zoom-in simulations of overdense, underdense and mean density regions at much higher particle resolution ($4\times10^4$ $h^{-1}\,M_\odot$). The main purpose of this simulation suite is to extend the concentration-mass relation of dark matter halos down to masses below those typically available in large cosmological simulations. The three different density regions available at higher resolution provide a better understanding of the effect of the local environment on halo concentration, known to be potentially important for small simulation boxes and small halo masses. Yet, we find the correction to be small in comparison with the scatter of halo concentrations. We conclude that zoom simulations, despite their limited representativity of the volume of the Universe, can be effectively used for the measurement of halo concentrations at least at the halo masses probed by our simulations. In any case, after a precise characterization of this effect, we develop a robust technique to extrapolate the concentration values found in zoom simulations to larger volumes with greater accuracy. All together, Lomonosov provides a measure of the concentration-mass relation in the halo mass range $10^7-10^{10}$ $h^{-1}\,M_\odot$ with superb halo statistics. This work represents a first important step to measure halo concentrations at intermediate, yet vastly unexplored halo mass scales, down to the smallest ones. All Lomonosov data and files are public for community's use.

description: It is well known that the "store language" of every pushdown automaton -- the set of store configurations (state and stack contents) that can appear as an intermediate step in accepting computations -- is a regular language. Here many models of language acceptors with various data structures are examined, along with a study of their store languages. For each model, an attempt is made to find the simplest model that accepts their store languages. Some connections between store languages of one-way and two-way machines generally are demonstrated, as with connections between nondeterministic and deterministic machines. A nice application of these store language results is also presented, showing a general technique for proving families accepted by many deterministic models are closed under right quotient with regular languages, resolving some open questions (and significantly simplifying proofs for others that are known) in the literature. Lower bounds on the space complexity for recognizing store languages for the languages to be non-regular are obtained.

description: Light Axionic Dark Matter, motivated by string theory, is increasingly favored for the "no-WIMP era". Galaxy formation is suppressed below a Jeans scale, of $\simeq 10^8 M_\odot$ by setting the axion mass to, $m_B \sim 10^{-22}$eV, and the large dark cores of dwarf galaxies are explained as solitons on the de-Broglie scale. This is persuasive, but detection of the inherent scalar field oscillation at the Compton frequency, $ω_B= (2.5{\rm \, months})^{-1}(m_B/10^{-22}eV)$, would be definitive. By evolving the coupled Schrödinger-Poisson equation for a Bose-Einstein condensate, we predict the dark matter is fully modulated by de-Broglie interference, with a dense soliton core of size $\simeq 150pc$, at the Galactic center. The oscillating field pressure induces General Relativistic time dilation in proportion to the local dark matter density and pulsars within this dense core have detectably large timing residuals, of $\simeq 400nsec/(m_B/10^{-22}eV)$. This is encouraging as many new pulsars should be discovered near the Galactic center with planned radio surveys. More generally, over the whole Galaxy, differences in dark matter density between pairs of pulsars imprints a pairwise Galactocentric signature that can be distinguished from an isotropic gravitational wave background.
