description: Incompressible 3D Euler equations develop high vorticity in very thin pancake-like regions from generic large-scale initial conditions. In this work we propose an exact solution of the Euler equations for the asymptotic pancake evolution. This solution combines a shear flow aligned with an asymmetric straining flow, and is characterized by a single asymmetry parameter and an arbitrary transversal vorticity profile. The analysis is based on detailed comparison with numerical simulations performed using a pseudo-spectral method in anisotropic grids of up to 972 x 2048 x 4096.

description: As a contribution to reproducible research, this paper presents a framework and a database to improve the development, evaluation and comparison of methods for gait recognition from motion capture (MoCap) data. The evaluation framework provides implementation details and source codes of state-of-the-art human-interpretable geometric features as well as our own approaches where gait features are learned by a modification of Fisher's Linear Discriminant Analysis with the Maximum Margin Criterion, and by a combination of Principal Component Analysis and Linear Discriminant Analysis. It includes a description and source codes of a mechanism for evaluating four class separability coefficients of feature space and four rank-based classifier performance metrics. This framework also contains a tool for learning a custom classifier and for classifying a custom query on a custom gallery. We provide an experimental database along with source codes for its extraction from the general CMU MoCap database.

description: The incompressible three-dimensional ideal flows develop very thin pancake-like regions of increasing vorticity. These regions evolve with the scaling $ω_{\max}(t)\propto\ell(t)^{-2/3}$ between the vorticity maximum and pancake thickness, and provide the leading contribution to the energy spectrum, where the gradual formation of the Kolmogorov interval $E_{k}\propto k^{-5/3}$ is observed for some initial flows [Agafontsev et. al, Phys. Fluids 27, 085102 (2015)]. With the massive numerical simulations, in the present paper we study the influence of initial conditions on the processes of pancake formation and the Kolmogorov energy spectrum development.

description: This work offers a design of a video surveillance system based on a soft biometric -- gait identification from MoCap data. The main focus is on two substantial issues of the video surveillance scenario: (1) the walkers do not cooperate in providing learning data to establish their identities and (2) the data are often noisy or incomplete. We show that only a few examples of human gait cycles are required to learn a projection of raw MoCap data onto a low-dimensional sub-space where the identities are well separable. Latent features learned by Maximum Margin Criterion (MMC) method discriminate better than any collection of geometric features. The MMC method is also highly robust to noisy data and works properly even with only a fraction of joints tracked. The overall workflow of the design is directly applicable for a day-to-day operation based on the available MoCap technology and algorithms for gait analysis. In the concept we introduce, a walker's identity is represented by a cluster of gait data collected at their incidents within the surveillance system: They are how they walk.

description: Die zunehmende Objektivierung der Natur zu Gunsten des Kapitalismus führt dazu, dass diese immer stärker ausgebeutet wird. Pflanzen werden vorrangig als Nahrungsgrundlage oder Rohstoff betrachtet, aber nicht als ein dem Menschen gleichgestellter Teil des Ökosystems Erde. Diese Sichtweise verstärkte sich besonders mit der industriellen Revolution, die in der zweiten Hälfte des 18. Jahrhunderts begann. Johann Wolfgang von Goethe erlebte die Anfänge der Modernisierung mit und beurteilte die gesellschaftlichen und politischen Ereignisse als sehr kritisch. Der Dichter betrachtete die Natur nie als Objekt, sondern immer als ein ihm gleichwertiges Subjekt, welches starken Einfluss auf sein Inneres und sein Verhalten gegenüber der Umwelt hat. Diese Sichtweise zeigte sich auch in seinem Schreiben und ist besonders in seinen Lebenswerken Faust I (1808) und Faust II (1832) eingeschrieben. Die zunehmende Entfremdung von der Natur ist gegenwärtig unter anderem in den Klassenzimmern des 21. Jahrhunderts spürbar. Im Rahmen dieser Arbeit wurden daher fächerübergreifende (Deutsch und Biologie) Unterrichtsmaterialien entwickelt, die die Tragödie Faust I (1808) zur Grundlage haben. Deren Ziel ist es, dass die Lernenden die Pflanzen als Subjekt begreifen. Dies soll die Basis sein, auf der sich eine nachhaltige und wertschätzende Haltung den Pflanzen und in weiterer Folge auch der Umwelt gegenüber entwickeln kann. Dies fordert auch der Grundsatzerlass zur Bildung für nachhaltige Entwicklung, welchem die Unterrichtsmaterialien entsprechen.
description: The increasing objectification of nature in favor of capitalism means that it is increasingly being exploited. Plants are primarily considered as a food source or raw material, but not as a human-equal part of the earth's ecosystem. This perspective became particularly strong with the industrial revolution that began in the second half of the 18th century. Johann Wolfgang von Goethe witnessed the beginnings of modernization and assessed the social and political events very critical. The poet never considered nature as an object, but always as a subject of equal value, which has a strong influence on his interior and his behaviour towards the environment. This perspective was also evident in his writing and is particularly inscribed in his life's works Faust I (1808) and Faust II (1832). The increasing alienation from nature can currently be felt, among other things, in the classrooms of the 21st century. As part of this work, interdisciplinary (German and biology) teaching materials were developed that are based on the tragedy Faust I (1808). Learners should understand plants as subjects. This should be the basis on which a sustainable and appreciative attitude towards the plants and subsequently also the environment is able to develop. The basic decree on education for sustainable development, to which the teaching materials correspond, are also requiring this learning goal.

description: We investigate the computational structure of a paradigmatic example of distributed social interaction: that of the open-source Wikipedia community. We examine the statistical properties of its cooperative behavior, and perform model selection to determine whether this aspect of the system can be described by a finite-state process, or whether reference to an effectively unbounded resource allows for a more parsimonious description. We find strong evidence, in a majority of the most-edited pages, in favor of a collective-state model, where the probability of a "revert" action declines as the square root of the number of non-revert actions seen since the last revert. We provide evidence that the emergence of this social counter is driven by collective interaction effects, rather than properties of individual users.

description: Auf die Forschungsfrage, welche Potenziale und welche Herausforderungen das Arbeiten mit literarischen Texten im Kontext Deutsch als Zweitsprache in der Erwachsenenbildung birgt, kann vielfältig geantwortet werden. Sei es aus einer kulturwissenschaftlichen Perspektive gesprochen oder im Hintergrund von sprachbezogenen Ansätzen, Literatur bereichert das Sprachenlernen und den Prozess der Lernenden, sich die Sprache anzueignen. Es konnte gezeigt werden, wie Literarizität einen produktiven Zugang zur Sprache schafft. Basierend auf dem Forschungsansatz des Desgin Based Research wurden Unterrichtsmaterialien zu ausgewählten Texten von Friederike Mayröcker, Yoko Tawada, Traude Veran, Rose Ausländer und Veza Canetti für die Zielgruppe Frauen* entwickelt. Die Analyse der daraus entstandenen Lernendenprodukte zeigte einerseits, wie produktiv, im Sinne von sprachlichem Output, das Arbeiten mit Literatur sein kann, und darüber hinaus, wie berührend und persönlich die Auseinandersetzung mit den Texten ist. Neben den Aspekten Freund:innenschaft, Geschlecht, Muttersprache oder Zukunftspläne, wurde an und mit sprachlichen Strukturen gearbeitet. Hier konnte eine der Herausforderungen verortet werden, die eine Adaptierung im Sinne einer zyklischen Materialentwicklung nach sich zog. Die Bedeutung einer Überarbeitungsphase im Schreibprozess der Lernenden und zusätzlich einer adäquaten Aufgabenstellung zu den jeweiligen Vorlagentexten konnte so verdeutlicht werden. Die empirische Untersuchung veranschaulicht, warum literarische Texte ausgiebig im Deutsch als Zweitsprache Unterricht Eingang finden sollten und zeigt, wie die die Offenheit literarischer Texte produktiv genutzt werden kann.

description: Gait recognition from motion capture data, as a pattern classification discipline, can be improved by the use of machine learning. This paper contributes to the state-of-the-art with a statistical approach for extracting robust gait features directly from raw data by a modification of Linear Discriminant Analysis with Maximum Margin Criterion. Experiments on the CMU MoCap database show that the suggested method outperforms thirteen relevant methods based on geometric features and a method to learn the features by a combination of Principal Component Analysis and Linear Discriminant Analysis. The methods are evaluated in terms of the distribution of biometric templates in respective feature spaces expressed in a number of class separability coefficients and classification metrics. Results also indicate a high portability of learned features, that means, we can learn what aspects of walk people generally differ in and extract those as general gait features. Recognizing people without needing group-specific features is convenient as particular people might not always provide annotated learning data. As a contribution to reproducible research, our evaluation framework and database have been made publicly available. This research makes motion capture technology directly applicable for human recognition.

description: We study symmetry protected features in the quasiparticle interference (QPI) pattern of 2D systems with mirror symmetries and time-reversal symmetry, around a single static point impurity. We show that, in the Fourier transformed local density of states (FT-LDOS), $ρ(\bq,ω)$, while the position of high intensity peaks generically depends on the geometric features of the iso-energy contour at energy $ω$, the \emph{absence} of certain peaks is guaranteed by the opposite mirror eigenvalues of the two Bloch states that are (i) on the mirror symmetric lines in the Brillouin zone (BZ) and (ii) separated by scattering vector $\bq$. We apply the general result to the QPI on the $ $-surface of topological crystalline insulator Pb$_{1-x}$Sn$_x$Te and predict all vanishing peaks in $ρ(\bq,ω)$. The model-independent analysis is supported by numerical calculations using an effective four-band model derived from symmetry analysis.

description: We present a novel functional for spin density functional theory aiming at the description of non-collinear magnetic structures. The construction of the functional employs the spin-spiral-wave state of the uniform electron gas as reference system. We show that the functional depends on transverse gradients of the spin magnetization, i.e., in contrast to the widely used local spin density approximation, the functional is sensitive to local changes of the direction of the spin magnetization. As a consequence the exchange-correlation magnetic field is not parallel to the spin magnetization and a local spin-torque is present in the ground state of the Kohn-Sham system. As a proof-of-principle we apply the functional to a Chromium mono-layer in the non-collinear ${120^{\circ}}$-N{é}el state.

Interestingly, rigorous correctness proofs for some of the reductions are missing in the literature.

description: In this work, we propose a distributed rate allocation algorithm that minimizes the average decoding delay for multimedia clients in inter-session network coding systems. We consider a scenario where the users are organized in a mesh network and each user requests the content of one of the available sources. We propose a novel distributed algorithm where network users determine the coding operations and the packet rates to be requested from the parent nodes, such that the decoding delay is minimized for all the clients. A rate allocation problem is solved by every user, which seeks the rates that minimize the average decoding delay for its children and for itself. Since the optimization problem is a priori non-convex, we introduce the concept of equivalent packet flows, which permits to estimate the expected number of packets that every user needs to collect for decoding. We then decompose our original rate allocation problem into a set of convex subproblems, which are eventually combined to obtain an effective approximate solution to the delay minimization problem. The results demonstrate that the proposed scheme eliminates the bottlenecks and reduces the decoding delay experienced by users with limited bandwidth resources. We validate the performance of our distributed rate allocation algorithm in different video streaming scenarios using the NS-3 network simulator. We show that our system is able to take benefit of inter-session network coding for simultaneous delivery of video sessions in networks with path diversity.

We prove that if f is a birational contraction associated to an extremal ray $ R \subset \bar {NE(X)}$ such that R.(K_X+(n-2)L)<0, then f is a weighted blow-up of a smooth point. We then classify divisorial contractions associated to extremal rays R such that R.(K_X+rL)<0, where r is a non-negative rational number, and the fibres of f have dimension less or equal to r+1.

description: The incompressible three-dimensional Euler equations develop very thin pancake-like regions of increasing vorticity. These regions evolve with the scaling $ω_{max}\sim\ell^{-2/3}$ between the vorticity maximum and the pancake thickness, as was observed in the recent numerical experiments [D.S. Agafontsev et al, Phys. Fluids 27, 085102 (2015)]. We study the process of pancakes' development in terms of the vortex line representation (VLR), which represents a partial integration of the Euler equations with respect to conservation of the Cauchy invariants and describes compressible dynamics of continuously distributed vortex lines. We present, for the first time, the numerical simulations of the VLR equations with high accuracy, which we perform in adaptive anisotropic grids of up to $1536^3$ nodes. With these simulations, we show that the vorticity growth is connected with the compressibility of the vortex lines and find geometric properties responsible for the observed scaling $ω_{max}\sim\ell^{-2/3}$.

Va die COVID-19 Pandemie sowie die Verbreitung von „Fake-News“ hat die Forderung nach freiem, unbeschränktem und kostenlosem Zugang zu wissenschaftlichen Informationen gefördert, und mündete in Folge in unzähligen nationalen und internationalen Initiativen zur Förderung von Open Access. Während über die Wichtigkeit der wissenschaftlichen Forschung und der allgemeinen Dissemination dieser Einigkeit herrscht, liegt die Art und Weise der Verbreitung im Dissens. Beginnend mit den Ursprüngen der Open Access-Bewegung und deren rechtlicher Rahmenbedingungen, wird in dieser Arbeit nach vermeintlichen Pflichten zur Veröffentlichung und Verbreitung wissenschaftlicher Informationen gesucht, welche von Urheber:innen mithilfe von öffentlichen Mitteln bzw. auf öffentlich finanzierten Forschungseinrichtungen geschaffen worden sind.

Especially the COVID-19 pandemic as well as the spreading of "fake news" has fostered the demand for free and unrestricted access to scientific information in the sense of OA, and subsequently resulted in countless national and international initiatives to promote Open Access. While there is agreement on the importance of scholarly research and the general dissemination of it, there is dissent on the manner of dissemination. Beginning with the origins of the OA movement and its legal framework, this paper will look for alleged obligations to publish and disseminate scholarly information that have been created by authors with the help of public funds respectively at publicly funded research institutions.

description: We study a model of bosons in the lowest Landau level in a rotating trap where the confinement potential is a sum of a quadratic and a quartic term. The quartic term improves the stability of the system against centrifugal deconfinement and allows to consider rotation frequencies beyond the frequency of the quadratic part. The interactions between particles are modeled by a Dirac delta potential. We derive rigorously conditions for ground states of the system to be strongly correlated in the sense that they are confined to the kernel of the interaction operator, and thus contain the correlations of the Bose-Laughlin state. Rigorous angular momentum estimates and trial state arguments indicate a transition from a pure Laughlin state to a state containing in addition a giant vortex at the center of the trap (Laughlin quasi-hole). There are also indications of a second transition where the density changes from a flat profile in a disc or an annulus to a radial Gaussian confined to a thin annulus.
title: Dolmetschen in Krisensituationen - Dolmetscher*innen als Akteur*innen der Versicherheitlichung
Creators: name: Kernegger, Marco
Year: 2023

description: Das Ziel der hier vorliegenden Arbeit ist es eine dolmetschwissenschaftliche Literaturanalyse, die eine Brücke zwischen der Versicherheitlichungstheorie (securitization theory) der internationalen Beziehungen und dem Dolmetschen in der Politik und Diplomatie darstellt. Dazu wurden sowohl eine primäre als auch eine sekundäre Forschungsfragen formuliert: Welche Rolle spielen Dolmetscher*innen in der Bewältigung von politischen Krisensituationen? (Primär) Welche Herausforderungen ergeben sich für Krisendolmetscher*innen aus der Sicherheitsforschung der internationalen Beziehungen? (Sekundär) Zur Beantwortung dieser Forschungsfragen wurde die Methode der Scoping Review herangezogen in Kombination mit dolmetschpraktischen Fallbeispielen, um den Forschungsstand des Krisendolmetschens zu analysieren und Forschungslücken aufzeigen. Die Literaturanalyse hat ergeben, dass sich die Translationswissenschaft immer mehr den Handlungen der Dolmetscher*innen als Individuen zuwendet und ihnen damit auch eine gewisse Machtstellung zuschreibt. Dolmetscher*innen verfügen über eine Bandbreite an Vorgehensweisen und Werkzeugen, um Konfliktsituationen vorzubeugen beziehungsweise aufzulösen und haben in diesem Rahmen auch die Möglichkeit direkt ins politische Machtgefüge einzugreifen und diskursbeeinflussend zu wirken. Während diese erhöhte Machtstellung der Dolmetscher*innen zur Flexibilisierung und Professionalisierung der Dolmetschpraxis beiträgt, kann dies auch missbraucht werden und besonders Laiendolmetscher*innen, die selbst in Krisensituationen involviert sind, zu Handlungen verleiten, die den professionellen und ethischen Grundsätzen der Dolmetschpraxis widersprechen. Die Versicherheitlichung beschreibt den Prozess der Krisenkommunikation beziehungsweise der Überzeugung der Rezipient*innen von der Bedrohlichkeit eines Themas und der damit einhergehende Handlungsaufruf beziehungsweise der Rechtfertigung außerordentlicher Maßnahmen. Hier ist es die Aufgabe der Dolmetscher*innen diese Sprechakte so in den Zieltext zu übertragen, dass dieser Ausdruck der Bedrohlichkeit beziehungsweise die gewünschten Handlungsaufforderungen von den Zieltextrezipient*innen verstanden werden. Es hat sich gezeigt, dass während sich zum Thema Dolmetschen in der Politik und Diplomatie und Dolmetschethik eine größere Bandbreite an Literatur sowohl auf Deutsch als auch auf Englisch finden lässt, das Thema Krisendolmetschen wenig untersucht wurde, mit Ausnahme des Konfliktdolmetschens. Durch die Verbindung des Dolmetschens in der Politik und Diplomatie und der Versicherheitlichung ergibt sich darüber hinaus ein ganz neues Forschungsfeld der Dolmetschwissenschaft.

description: We study the combined effect of world-volume and background fluxes on Euclidean D3-brane instantons in F-theory compactifications. We derive an appropriate form of the fermionic effective action, in which the fermions are topologically twisted and the dynamical effect of fluxes, non-trivial axio-dilaton and warping is taken into account. We study the structure of fermionic zero modes, which determines the form of possible non-perturbative superpotential and F-terms in the four-dimensional effective action. Invariance under SL(2,Z) is discussed in detail, which allows for an interpretation of the results in terms of the dual M5-brane instanton in the M-theory picture. We also provide the perturbative IIB description in the orientifold limit, when available. Furthermore, we consider the possible inclusion of supersymmetry breaking bulk fluxes and discuss its implications.

description: Macro-economic models describe the dynamics of economic quantities. The estimations and forecasts produced by such models play a substantial role for financial and political decisions. In this contribution we describe an approach based on genetic programming and symbolic regression to identify variable interactions in large datasets. In the proposed approach multiple symbolic regression runs are executed for each variable of the dataset to find potentially interesting models. The result is a variable interaction network that describes which variables are most relevant for the approximation of each variable of the dataset. This approach is applied to a macro-economic dataset with monthly observations of important economic indicators in order to identify potentially interesting dependencies of these indicators. The resulting interaction network of macro-economic indicators is briefly discussed and two of the identified models are presented in detail. The two models approximate the help wanted index and the CPI inflation in the US.

description: Semantic Web Rule Language (SWRL) combines OWL (Web Ontology Language) ontologies with Horn Logic rules of the Rule Markup Language (RuleML) family. Being supported by ontology editors, rule engines and ontology reasoners, it has become a very popular choice for developing rule-based applications on top of ontologies. However, SWRL is probably not go-ing to become a WWW Consortium standard, prohibiting industrial acceptance. On the other hand, SPIN (SPARQL Inferencing Notation) has become a de-facto industry standard to rep-resent SPARQL rules and constraints on Semantic Web models, building on the widespread acceptance of SPARQL (SPARQL Protocol and RDF Query Language). In this paper, we ar-gue that the life of existing SWRL rule-based ontology applications can be prolonged by con-verting them to SPIN. To this end, we have developed the SWRL2SPIN tool in Prolog that transforms SWRL rules into SPIN rules, considering the object-orientation of SPIN, i.e. linking rules to the appropriate ontology classes and optimizing them, as derived by analysing the rule conditions.

Previously recorded. NEW ZEALAND, Fiordland (Crooked Arm Head, Only Island, Long Sound, Nine Fathom Passage, Dusky Sound, Thompson Sound (Page et al. 2014); South Australia, (York Peninsula, Taipara Reef, Eyre Peninsula, Cathedral Rock and Kangaroo Island, Investigator Strait); Western Australia (Esperance, Oyster Harbour); Victoria (Western Port) (see Kott 1962, 1975, 1976, 2001). Description Pale orange colonies have characteristically large common cloacal apertures and zooids arranged in groups, suspended in test connectives visible through a semi-transparent gelatinous test (Figure 6a). The zooids are 1.8–2.0 mm long. The thorax has a large atrial aperture that exposes most of the branchial sac. The branchial sac has 4 rows, approximately 10 stigmata per half-row. There are 2 testis follicles,divided by a straight vas deferens.The larvae characteristic of this species are large, with 3 long, slender lateral ampullae on each side of adhesive papillae on long stalks. Remarks Diplosoma velatum colonies are common on wharf piles and natural substrata throughout Bluff Harbour. They are easily distinguishable from a co-occurring species, Diplosoma listerianum (Milne Edwards, 1841), by their lobed, fleshy, sheet-like colonies.

description: We show that a given conformal boundary can have a rich and intricate space of supersymmetric supergravity solutions filling it, focusing on the case where this conformal boundary is a biaxially squashed Lens space. Generically we find that the biaxially squashed Lens space S^3/Z_p admits Taub-NUT-AdS fillings, with topology R^4/Z_p, as well as smooth Taub-Bolt-AdS fillings with non-trivial topology. We show that the Taub-NUT-AdS solutions always lift to solutions of M-theory, and correspondingly that the gravitational free energy then agrees with the large N limit of the dual field theory free energy, obtained from the localized partition function of a class of N=2 Chern-Simons-matter theories. However, the solutions of Taub-Bolt-AdS type only lift to M-theory for appropriate classes of internal manifold, meaning that these solutions exist only for corresponding classes of three-dimensional N=2 field theories.

title: Bayesian Hierarchical Modelling for Two-Dimensional Blood Pressure Data
Creators: name: Spyropoulou, Maria-Zafeiria
Publisher: name: University of Kent

description: Many real-world phenomena are naturally bivariate. This includes blood pressure, which comprises systolic and diastolic levels. Here, we develop a Bayesian hierarchical model that estimates these values and their interactions simultaneously, using sparse data that vary substantially between groups and over time. A key element of the model is a two-dimensional second-order Intrinsic Gaussian Markov Random Field (IGMRF), which captures non-linear trends in the variables and their interactions. The model is fitted using Markov chain Monte Carlo methods, with a block Metropolis-Hastings algorithm providing efficient updates. Performance is demonstrated using simulated and real data. Furthermore, IGMRFs can be used to induce conditional dependence in Bayesian hierarchical models. IGMRFs have both a precision matrix, which defines the neighbourhood structure of the model, and a precision, or scaling, parameter. Previous studies have shown the importance of selecting the prior of this scaling parameter appropriately for different types of IGMRF, as it can have a substantial impact on posterior results. The focus is on the two-dimensional case, where tuning of the parameter’s prior is achieved by mapping it to the marginal standard deviation of a two-dimensional IGMRF. We compare the effects of scaling various classes of IGMRF, to the application of blood pressure data.

On the Japanese Multiplication Method. A father-and-daughter dialogue
Creators: name: D'Agostini, G.
Publisher: name: arXiv
Year: 2018
Subjects: subject: History and Overview (math.HO)
subject: FOS: Mathematics

description: Recently the media broadcast the news, together with illustrative videos, of a so-called Japanese method to perform multiplication by hand without using the multiplication tables. "Goodbye multiplication tables" was the headline of several websites, including important ones, where news are however too often `re-posted' uncritically. The easy numerical examples could induce naive internauts to believe that, in a short future, multiplications could be really done without the knowledge of multiplication tables. This is what a girl expresses, with great enthusiasm, to her father. The dialogues described here, although not real, are likely and have been inspired by this episode, being Maddalena the daughter of the author. Obviously the revolutionary value of the new method is easily disassembled, while its educational utility is highlighted to show (or remember) the reasoning on which the method learned in elementary school is based, although mostly applied mechanically.

description: After the start of the LHC, a plethora of novel observables for jet tomography in heavy-ion collisions has appeared. Many of these studies have yielded counter-intuitive null results of apparently unmodified jets, which have sparked (sometimes exotic) theoretical efforts to explain these findings. However, it has to be realized that almost all current high P_T observables measure conditional probabilities of events, not probabilities. Thus, the correct starting point for their theoretical understanding is Bayes' formula, and the biases introduced by the conditioning are crucial to understanding the outcome. Once this is introduced properly into the modelling process, the counter-intuitive results are seen to find a natural explanation in terms of various biases and the puzzles largely disappear. In this work, a conceptual framework to classify the various observables according to the types of bias they are sensitive to is presented and illustrated with a large number of case studies ranging from simple jet finding to 2+1 dihadron triggered correlations.

description: We demonstrate formation of hierarchical structures in two-dimensional systems with multiple length scales in the inter-particle interaction. These include states such as clusters of clusters, concentric rings, clusters inside a ring, and stripes in a cluster. We propose to realize such systems in vortex matter (where a vortex is mapped onto a particle with multi-scale interactions) in layered superconducting systems with varying inter-layer thicknesses and different layer materials.
