description: We present an investigation of rapidly rotating (small Rossby number $Ro\ll 1$) and stratified turbulence where the stratification strength is varied from weak (large Froude number $Fr\gg1$) to strong ($Fr\ll1$). The investigation is set in the context of a reduced model derived from the Boussinesq equations that efficiently retains anisotropic inertia-gravity waves with order-one frequencies and highlights a regime of wave-eddy interactions. Numerical simulations of the reduced model are performed where energy is injected by a stochastic forcing of vertical velocity, which forces wave modes only. The simulations reveal two regimes characterized by the presence of well-formed, persistent and thin turbulent layers of locally-weakened stratification at small Froude numbers, and by the absence of layers at large Froude numbers. Both regimes are characterized by a large-scale barotropic dipole enclosed by small-scale turbulence. When the Reynolds number is not too large a direct cascade of barotropic kinetic energy is observed, leading to total energy equilibration. We examine net energy exchanges that occur through vortex stretching and vertical buoyancy flux and diagnose the horizontal scales active in these exchanges. We find that the baroclinic motions inject energy directly to the largest scales of the barotropic mode, implying that the large-scale barotropic dipole is not the end result of an inverse cascade within the barotropic mode.

description: We consider algorithms that, from an arbitrarily sampling of $N$ spheres (possibly overlapping), find a close packed configuration without overlapping. These problems can be formulated as minimization problems with non-convex constraints. For such packing problems, we observe that the classical iterative Arrow-Hurwicz algorithm does not converge. We derive a novel algorithm from a multi-step variant of the Arrow-Hurwicz scheme with damping. We compare this algorithm with classical algorithms belonging to the class of linearly constrained Lagrangian methods and show that it performs better. We provide an analysis of the convergence of these algorithms in the simple case of two spheres in one spatial dimension. Finally, we investigate the behaviour of our algorithm when the number of spheres is large.

description: Given a fully extended topological quantum field theory, the 'crossing with the circle' conditions establish that the dimension, or categorification thereof, of the quantum invariant assigned to a closed $k$-manifold $Σ$ is equivalent to that assigned to the ($k$+1)-manifold $Σ\times \mathbb S^1$. We compute in this manuscript these conditions for the 4-3-2-1 Dijkgraaf-Witten theory. In the context of the lattice Hamiltonian realisation of the theory, the quantum invariants assigned to the circle and the torus encode the defect open string-like and bulk loop-like excitations, respectively. The corresponding 'crossing with the circle' condition thus formalises the process by which loop-like excitations are formed out of string-like ones. Exploiting this result, we revisit the statement that loop-like excitations define representations of the linear necklace group as well as the loop braid group.

description: Properties of two-dimensional transition metal dichalcogenides are highly sensitive to the presence of defects in the crystal structure. A detailed understanding of defect structure may lead to control of material properties through defect engineering. Here we provide direct evidence for the existence of isolated, one-dimensional charge density waves at mirror twin boundaries in single-layer MoSe2. Our low-temperature scanning tunneling microscopy/spectroscopy measurements reveal a substantial bandgap of 60 - 140 meV opening at the Fermi level in the otherwise one dimensional metallic structure. We find an energy-dependent periodic modulation in the density of states along the mirror twin boundary, with a wavelength of approximately three lattice constants. The modulations in the density of states above and below the Fermi level are spatially out of phase, consistent with charge density wave order. In addition to the electronic characterization, we determine the atomic structure and bonding configuration of the one-dimensional mirror twin boundary by means of high-resolution non-contact atomic force microscopy. Density functional theory calculations reproduce both the gap opening and the modulations of the density of states.

description: Dieser Beitrag untersucht das Geschehen in Moskau 1812 anhand einer bislang fast unbekannten Quelle: den Kriegserinnerungen des deutschen Einwanderers Johannes Ambrosius Rosenstrauch (1768–1835). Rosenstrauch war erst Schauspieler in St. Petersburg, später Kaufmann in Moskau und zuletzt Pastor im ukrainischen Charkow. Der Artikel bespricht seine Biographie und die Rolle, die europäische Einwanderer wie er in den Prozessen der Modernisierung Moskaus gespielt haben. Danach werden drei Aspekte seines Kriegserlebnisses untersucht: sein kompliziertes Verhältnis zur russischen Bevölkerung; seine Stellung in den Netzwerken, die Russland mit Europa verbanden; und der Einfluss des Kriegs auf das weitere persönliche Schicksal Rosenstrauchs. Auf diese Weise ergibt sich die Chance, den individuellen Lebensweg eines Einzelnen mit den großen Linien der russisch-europäischen Begegnungen in den Napoleonischen Kriegen in Verbindung zu bringen.

description: We generalize the analytical investigation on the properties of $s$-wave holographic superconductors in the presence of Born-Infeld nonlinear electrodynamics by taking the backreaction into account. We find that in the presence of nonlinear gauge field, one can still employ the analytical method when the backreaction is turned on. Our calculation is based on the Sturm-Liouville eigenvalue problem, which is a variational method. For the system under consideration, we obtain the relation between the critical temperature and the charge density. We find that both backreaction and Born-Infeld parameters decrease the critical temperature of the superconductor and make the condensation harder. At the ned of paper, we calculate the critical exponent associated with the condensation near the critical temperature and find that it has the universal value $1/2$ of the mean field theory.

description: Most image data available are often stored in a compressed format, from which JPEG is the most widespread. To feed this data on a convolutional neural network (CNN), a preliminary decoding process is required to obtain RGB pixels, demanding a high computational load and memory usage. For this reason, the design of CNNs for processing JPEG compressed data has gained attention in recent years. In most existing works, typical CNN architectures are adapted to facilitate the learning with the DCT coefficients rather than RGB pixels. Although they are effective, their architectural changes either raise the computational costs or neglect relevant information from DCT inputs. In this paper, we examine different ways of speeding up CNNs designed for DCT inputs, exploiting learning strategies to reduce the computational complexity by taking full advantage of DCT inputs. Our experiments were conducted on the ImageNet dataset. Results show that learning how to combine all DCT inputs in a data-driven fashion is better than discarding them by hand, and its combination with a reduction of layers has proven to be effective for reducing the computational costs while retaining accuracy.

description: Very recently, the Fermi-Lab reported the new experimental combined results on the magnetic momentum of muon with a 4.2$σ$ discrepancy compared with the expectation of the Standard Model \cite{Fermi_Lab}. A new light gauge boson $X$ in the $L_μ-L_τ$ model provides a good explanation for the $g-2$ anomaly. A Dirac fermion dark matter with a large $L_μ-L_τ$ charge can explain both the $g-2$ anomaly and the dark matter relic density \cite{Asai_2021}. In this work, we focus on the case that the mass of the dark matter is larger than the mass of muon (i.e. $m_Ψ > m_μ$) for which the channel $ΨΨ\rightarrow μ^- μ^+$ opens. Although the cross section $(σv)_{μ^{-}μ^{+}}$ is smaller by a factor of $1/q_Ψ^2$ ($q_Ψ$ represents the $L_μ-L_τ$ charge of the dark matter) compared with the channel $ΨΨ\rightarrow XX \rightarrow νν\barν\barν$, the resulting secondary electrons and positrons could imprint on their spectra above GeV energies due to the reacceleration effect of cosmic ray propagation. We use the AMS-02 measurements of electrons and positrons to constrain the annihilation cross section of the channel $ΨΨ\rightarrow μ^{-}μ^{+}$, which rules out part of the parameter space of the large $L_μ-L_τ$ charged dark matter model to account for the muon $g-2$ anomaly.

description: Wissenstransfer spielte eine zentrale Rolle im Prozess der Herausbildung akademischer Disziplinen bzw. der Reform der traditionellen Wissenskulturen in einer Vielzahl nichtwestlicher Länder im 20. Jahrhundert. Ein Beispiel für solch einen Modernisierungsprozess bildet der Einfluss der deutschen Bildung und Pädagogik auf Taiwan. Der Aufsatz beginnt mit einer Analyse der neun einzigen chinesischen Pädagogikstudenten, die ihre akademischen Grade in Deutschland zwischen 1920 und 1949 erwarben, danach nach China zurückkehrten und nach 1949 in Taiwan als „Wissensmediatoren“ fungierten. Es wird gezeigt, wie diese Pädagogen versuchten, nach dem Vorbild der geisteswissenschaftlichen Tradition der deutschen Erziehungswissenschaft die taiwanesische Pädagogik und das Bildungssystem, das bis dahin vom amerikanischen Wissenschaftsparadigma dominiert war, zu reformieren. Dies war mit dem Anspruch verbunden, anhand der kulturellen und philosophischen Annahmen der „Kulturpädagogik“ westliche und chinesische Kultur in Taiwan miteinander harmonisch zu verbinden und angesichts der politischen Ereignisse in China 949 neue Lösungen für den Bildungsbereich zu suchen. Der Analyse liegen die theoretischen Annahmen des Wissenstransfers von Steiner-Khamsi und Schriewer zugrunde.

Der vorliegende Beitrag beleuchtet Akteure und Objekte von Bildungstransfer im China des ausgehenden 19. und frühen 20. Jahrhunderts, als China in wachsendem Maße als Teil einer Weltgesellschaft gedacht wurde. Nach einem Überblick über die unterschiedlichen chinesischen Rezeptionsphasen jener Zeit wendet sich der Beitrag der Frage zu, mit welchen semantischen Ressourcen chinesische Bildungsakteure agieren konnten und welche Rolle dabei vermittelnde Instanzen wie Übersetzungen oder „dritte“ Länder wie Japan spielten. Abschließend werden diese Phänomene unter Rückgriff auf theoretische Zugänge zu Rezeption und Aneignung konzeptualisiert.

Imperial Language Policy in the Nineteenth Century.

Publisher: name: Leipziger Universitätsverlag
Year: 2012

description: Heute ist Englisch, basierend auf der Anzahl der Sprecher und vor allem aufgrund seiner Verbreitung in allen modernen Medien, als Weltsprache anerkannt und als globales Kommunikationsmittel aus unserem Alltag nicht mehr wegzudenken. Die Untersuchung konzentriert sich auf die Anfänge des Englischen als imperiale Sprache und analysiert am Beispiel von Süd- und Südostasien seine Verbreitung im 19. Jahrhundert. Dabei zeigt sich, dass mit Bildungspolitik in den Kolonien immer auch der Versuch verbunden war, sprachpolitische Entwicklungen und damit einhergehende Aufstiegschancen der Kolonisierten zu steuern. Da sie jedoch nur ein Element in einem komplexen und keinesfalls immer kohärenten Gefüge von imperialer Politik in London, Entscheidungen „on the spot“ und „local agency“ war, konnte sie nur bedingt Wirkung zeigen. Dennoch lässt sich in den Quellen zur Bildungs- und Sprachpolitik besonders gut nachlesen, welche Rolle einerseits die Zivilisierungsmission und andererseits eher wirtschaftlich orientierte Herangehensweisen im politischen Denken und im kolonialen Handeln spielten.

description: Dieser Artikel untersucht Prozesse von Erkenntnistransfer unter staatlicher Vermittlung. Er überträgt erstmals den überzeugenden theoretischen Ansatz von Schriewer, Martínez (2004) und anderen auf einen speziellen Kontext kolonialer Bildung in Britisch-Indien. Der Artikel nimmt einen Einzelaspekt des Kolonialdiskurses in den Blick, nämlich Schul(buch)texte, um an ihnen exemplarisch einen allgemeineren Zusammenhang zu verdeutlichen. Indem er seinen Gegenstand während Schlüsseletappen der britischen Herrschaft analysiert, lotet der Beitrag aus, wie der Staat Erkenntnistransfer nach seinen eigenen Regeln steuert. Er berücksichtigt die Rolle kommunaler, klassenbedingter und regionaler Befindlichkeiten, sieht aber im Herrschaftsgeschäft des Empire auch, wie der wechselnde Charakter kolonialer Macht ein stärkeres Metanarrativ organisierte. Dieses Narrativ unterstrich „Bildungsdefizite“, die „Maßnahmen“ erforderten, und war vor allem für das „Mutterland“ Großbritannien sichtbar. Auf diese Weise entstanden falsche imperiale Dualitäten und der einst fruchtbare intellektuelle Austausch zwischen Ost und West verstummte.

description: Let G be a graph with vertex set V (G) and edge set E(G). The first generalized multiplicative Zagreb index of G is M_1(G) and the second multiplicative Zagreb index is M_2(G). The multiplicative Zagreb indices have been the focus of considerable research in computational chemistry dating back to Narumi and Katayama in 1980s. In this paper, we generalize Narumi-Katayama index and the first multiplicative index, where c = 1, 2, respectively, and extend the results of Gutman to the generalized tree, the k-tree, where the results of Gutman are for k = 1. Additionally, we characterize the extremal graphs and determine the exact bounds of these indices of k-trees, which attain the lower and upper bounds.

description: Der Telegraph entwickelte sich nie zu einem weltweit verbreiteten sozialen Instrument der Kommunikation zwischen Privatpersonen. Dieser Aufsatz porträtiert drei Reformer - Ernest Ayscoghe Floyer, John Henniker Heaton und Heinrich von Stephan - die diese Situation zu ändern antraten und argumentierten, dass der gesellschaftliche Gebrauch des Telegraphen erweitert werden sollte. Sie trafen auf der Konferenz der Internationalen Telegraphenunion in Berlin 885 zusammen. Das Ereignis hatte deutlich niedrigere Preise im europäischen Netz zur Folge, die auf einen Vorschlag von Stephans zurückgingen, der die Asymmetrien im Gebrauch des Telegraphen abbauen wollte. Dies scheint symptomatisch für ein allgemeineres Muster in der Entwicklung von Infrastrukturen, demzufolge europäische Arrangements als Zwischenschritt auf dem Weg zu globalen Lösungen angesehen wurden.

description: This work concerns finite free complexes with finite length homology over a commutative noetherian local ring $R$. The focus is on complexes that have length $\mathrm{dim}\, R$, which is the smallest possible value, and in particular on free resolutions of modules of finite length and finite projective dimension. Lower bounds are obtained on the Euler characteristic of such short complexes when $R$ is a strict complete intersection, and also on the Dutta multiplicity, when $R$ is the localization at its maximal ideal of a standard graded algebra over a field of positive prime characteristic. The key idea in the proof is the construction of a suitable Ulrich module, or, in the latter case, a sequence of modules that have the Ulrich property asymptotically, and with good convergence properties in the rational Grothendieck group of $R$. Such a sequence is obtained by constructing an appropriate sequence of sheaves on the associated projective variety.

description: Triple nodal points are degeneracies of energy bands in momentum space at which three Hamiltonian eigenstates coalesce at a single eigenenergy. For spinless particles, the stability of a triple nodal point requires two ingredients: rotation symmetry of order three, four or six; combined with mirror or space-time-inversion symmetry. However, despite ample studies of their classification, robust boundary signatures of triple nodal points have until now remained elusive. In this work, we first show that pairs of triple nodal points in semimetals and metals can be characterized by Stiefel-Whitney and Euler monopole invariants, of which the first one is known to facilitate higher-order topology. Motivated by this observation, we then combine symmetry indicators for corner charges and for the Stiefel-Whitney invariant in two dimensions with the classification of triple nodal points for spinless systems in three dimensions. The result is a complete higher-order bulk-boundary correspondence, where pairs of triple nodal points are characterized by fractional jumps of the hinge charge. We present minimal models of the various species of triple nodal points carrying higher-order topology, and illustrate the derived correspondence on Sc$_3$AlC which becomes a higher-order triple-point metal in applied strain. The generalization to spinful systems, in particular to the WC-type triple-point material class, is briefly outlined.

description: Viele Nationen sahen die Telegraphenverbindungen, insbesondere die Unterseekabel, als strategische Faktoren. Portugals Regierung strebte eine „Modernisierung“ des Landes an, indem es 1854 ein Telegraphennetz aufsetzte. Begrenzte Ressourcen zwangen die portugiesischen Politiker, Techniker und Manager, die Reichweite und Effizienz des Netzes zu optimieren, indem sie Telegraph, Telefon und Radio miteinander verbanden. Portugals geographische Lage machte es zugleich zu einer Peripherie und zu einem Zentrum anderer Peripherien, besonders der Atlantischen Inseln und der afrikanischen Kolonien. Dies bescherte portugiesischen Territorien eine Schlüsselposition im globalen Telegraphennetzwerk und machte es zu einem bedeutenden Faktor von dessen Heraufkunft und Kontrolle zwischen ca. 1860 und 1930. Der vorliegende Artikel konzentriert sich auf die Beziehungen dieser Tatsache zu wechselnden geopolitischen Konstellationen und der nationalen Modernisierungsabsicht.

description: Der elektrische Signale verarbeitende Telegraph habe, so wird oft gesagt, Zeit und Raum „ausgelöscht“, indem er Kommunikation vom physischen Transport der Nachrichten trennte. Der Artikel prüft die empirische Stichhaltigkeit einer solchen Feststellung durch den Vergleich der Ausbreitungsgeschwindigkeit von Neuigkeiten in zwei schwedischen Provinzzeitungen zwischen 1850 und 1870. Die eine wurde im südschwedischen Helsingborg herausgegeben, wo eine gute Anbindung an klassische Transportwege bestand. Die andere erschien im Norden, in der weit abgeschiedeneren Stadt Piteå. Beide Orte waren seit den 1850er Jahren an das Telegraphennetz angeschlossen. Es ließe sich annehmen, dass die Unterschiede in ihrer relativen Distanz zur Hauptstadt Stockholm und zum europäischen Kontinent durch die neue Technologie aufgehoben würden, was sich am Zeitverzug der aufgenommenen Nachrichten messen lässt. Die Resultate zeigen, dass die neue Technologie im Süden rasch vollständig implementiert wurde, im Norden dagegen nur sporadisch zum Einsatz kam. Statt die Distanzen zu verringern führte die neue Technologie sogar zum Anwachsen der relativen Entfernung zwischen den Orten. Dies lag vor allem an Faktoren wie den Kosten für die Verwendung von Nachrichten, die über den Telegraphen übermittelt wurden, im Verhältnis zum Einkommen aus dem Zeitungsvertrieb, sowie den vermuteten Bedürfnissen der Leser.

description: Quantitative trading is an integral part of financial markets with high calculation speed requirements, while no quantum algorithms have been introduced into this field yet. We propose quantum algorithms for high-frequency statistical arbitrage trading in this work by utilizing variable time condition number estimation and quantum linear regression.The algorithm complexity has been reduced from the classical benchmark O(N^2d) to O(sqrt(d)(kappa)^2(log(1/epsilon))^2 )). It shows quantum advantage, where N is the length of trading data, and d is the number of stocks, kappa is the condition number and epsilon is the desired precision. Moreover, two tool algorithms for condition number estimation and cointegration test are developed.

Futurism, Universalism, and the Moral Agency of the Electric Telegraph

Year: 2011

description: Die Idee, dass der elektrische Telegraph in der Lage sei, Grenzen zu beseitigen und nationale wie internationale Konflikte zu überwinden, begleitet seine Geschichte, war aber besonders stark in der Zeit seiner Entwicklung und Ausbreitung über den gesamten Globus. Stimuliert von der Aufmerksamkeit, die die Bemühungen um ein atlantisches Kabel (1857–1866) fanden, wurde dieses Motiv Teil der Popularkultur. Von S. B. F. Morse bis H. G. Wells stellten sich viele vor, dass er Kriege beenden würde, indem er mit den Missverständnissen zwischen Völkern und Nationen aufräumen würde. Nationalismus, Sektierertum und „Partikularismen“ würden verschwinden, eine „universelle Union“ oder ein „Welt-Staat“ würden entstehen. Zentral für diese Annahme war der Glaube, dass der elektrische Telegraph eine große Handlungsmacht habe, nicht nur in Bezug auf soziale, wirtschaftliche und politische Veränderungen, sondern auch für die geistige, moralische und intellektuelle Verbesserung der Menschheit. Wie allerdings schon H. D. Thoreau vorausgesagt hatte, konnte der Telegraph selbst die intellektuelle oder moralische Qualität der Kommunikation nicht verbessern, ohne intelligente und moralische Nutzer würde diese neue Kommunikationsform nur beschleunigen, was die alten Medien, wie etwa die Tageszeitungen, bisher schon getan hatten.

description: Solar microwave type III pair burst is composed of normal and reverse-sloped (RS) burst branches with oppositely fast frequency drifts. It is the most sensitive signature of the primary energy release and electron accelerations in flares. This work reported 11 microwave type III pair events in 9 flares observed by radio spectrometers in China and the Czech Republic at frequency of 0.80 - 7.60 GHz during 1994 - 2014. These type III pairs occurred in flare impulsive and postflare phases with separate frequency in range of 1.08 - 3.42 GHz and frequency gap 10 - 1700 MHz. The frequency drift increases with the separate frequency (f_{x}), the lifetime of each burst is anti-correlated to f_{x}, while the frequency gap is independent to f_{x}. In most events, the normal branches are drifting obviously faster than the RS branches. The type III pairs occurring in flare impulsive phase have lower separate frequency, longer lifetime, wider frequency gap, and slower frequency drift than that occurring in postflare phase. And the latter always has strong circular polarization. Further analysis indicates that near the flare energy-release sites the plasma density is about 10^{10} - 10^{11},cm^{-3} and temperature higher than 10^{7} K . These results provide new constraints to the acceleration mechanism in solar flares.

We searched English language papers on PubMed/MEDLINE, SportsDiscus, CINAHL, and EBSCO for the following inclusion criteria: Participants aged between 11 and 17 years, studies had to include the Functional Movement Screen© (FMS©) and at least one of the following performance outcomes, highlighted by athletic development models (i.e., long-term athletic development (LTAD), youth physical development (YPD)): agility, speed, power, strength, endurance, and balance (YPD), fitness (LTAD), or sport-specific skill (LTAD and YPD). A total of 3146 titles were identified, with 13 relevant studies satisfying the inclusion criteria after full-text screening. The results of this systematic review suggest that children and youth who score highly on the FMS© also tend to have better scores for agility, running speed, strength, and cardiovascular endurance. The strength of associations was weak to moderate in nature. Only one study was considered or controlled for biological maturation in their analysis. These results provide evidence that, while there is a relationship between FMS© scores and tests of athletic performance in youth, they are not the same thing and should be considered conceptually different constructs.

description: Gaussian Mixture Models are a powerful tool in Data Science and Statistics that are mainly used for clustering and density approximation. The task of estimating the model parameters is in practice often solved by the Expectation Maximization (EM) algorithm which has its benefits in its simplicity and low per-iteration costs. However, the EM converges slowly if there is a large share of hidden information or overlapping clusters. Recent advances in manifold optimization for Gaussian Mixture Models have gained increasing interest. We introduce an explicit formula for the Riemannian Hessian for Gaussian Mixture Models. On top, we propose a new Riemannian Newton Trust-Region method which outperforms current approaches both in terms of runtime and number of iterations. We apply our method on clustering problems and density approximation tasks. Our method is very powerful for data with a large share of hidden information compared to existing methods.

description: Asymmetrie ist ein zentrales Konzept für das Verständnis der Rolle, die der Telegraph in der Geschichte der Globalisierung gespielt hat. Dieser Beitrag zeigt diese asymmetrische Entwicklung des globalen Telegraphennetzwerks und setzt sich mit einer allzu systemorientierten Sicht und einer weithin unkritischen Charakterisierung des Telegraphen als Motor der Globalisierung auseinander. Zwei Trends in der aktuellen Geschichtsschreibung sind dafür besonders ermutigend: Einerseits haben verschiedene Forscher begonnen, den scheinbar revolutionären Charakter des Telegraphen kritischer zu beurteilen, indem sie mehr Aufmerksamkeit auf die technologische Entwicklung vor dem Telegraphen und auf Kommunikationsstrategien, die parallel zu ihm entwickelt wurden, gelegt haben. Andererseits haben Untersuchungen des Telegraphen im imperialen Kontext die wechselseitige Abhängigkeit der imperialen Mächte unterstrichen und dabei Konflikte um die Ausweitung des Telegraphennetzwerkes in den Blick genommen. Die Einleitung zu diesem Themenheft schließt damit, dass sie Ideen, Materialität und Gebrauch als drei Perspektiven identifiziert, unter denen die Untersuchung der inhärenten Asymmetrien des globalen Telegraphennetzwerkes besonders fruchtbar erscheint.

description: This paper describes the data acquisition system used for data readout from a segmented detector of reactor antineutrinos with active shielding. Theoretical approach to the data acquisition is described and two possible solutions using QDCs and digitizers are discussed. Also described are the results of the DAQ performance during routine data taking operation of DANSS. DANSS (Detector of the reactor AntiNeutrino based on Solid Scintillator) is a project aiming to measure a spectrum of reactor antineutrinos using inverse beta decay (IBD) in a plastic scintillator. The detector is located close to an industrial nuclear reactor core and is covered by passive and active shielding. It is expected to have about 15000 IBD interactions per day. Light from the detector is sensed by PMT and SiPM.

description: Semantic interoperability of clinical data requires the use of a common vocabulary, such as SNOMED-CT. Unfortunately, mapping data to such a terminology is time-consuming and requires expert knowledge of both the dataset and the terminology. A viable alternative can be the reuse of codebooks - published dataset definitions which, in some cases, have already been mapped to a terminology. We designed the iCRF Generator, a tool which makes it easy to generate interoperable Case Report Forms (iCRFs) for several major EDCs, including Castor and REDCap. The tool currently provides access to multiple codebooks stored online in ART-DECOR and OpenEHR. These slides were used to introduce the iCRF Generator during Health-RI's data stewards course, June 2023.

Aeroacoustics of Twin Rectangular Jets Including Screech: Large-eddy Simulations with Experimental Validation

description: High-fidelity large-eddy simulations (LES) are performed to investigate aeroacoustic characteristics of jets issuing from twin rectangular nozzles with an aspect ratio of 2:1 at two over-expanded conditions and the design condition. For all three jet conditions simulated, LES predicts qualitatively similar near-field flow statistics to those measured at the University of Cincinnati. Using the Ffowcs Williams-Hawkings method, LES captures the fundamental screech tone and its harmonics fairly well at multiple observer locations in the far-field. Intense jet flapping motions in the near-field along the minor axis, which are influenced by jet-to-jet interactions, are found to correspond to those frequencies. Moreover, the predicted overall sound pressure levels are within 1-2 dB of the experimental measurements. However, the screech tones appear to be intermittent, as the twin-jet interaction pattern varies irregularly. To extract dominant flow structures at the screech frequencies and identify the twin-jet coupling modes, spectral proper orthogonal decomposition (SPOD) analysis is used. SPOD analysis recovers energetic peaks at the screech frequencies, and the corresponding leading modes indicate strong upstream radiation originating from the fifth/sixth shock-cells. For the two over-expanded conditions, the leading modes show anti-symmetric coupling in the minor axis at the fundamental screech frequencies. In contrast, the two jets behave symmetrically with respect to each other in the major axis, in line with the absence of jet flapping in this direction. Furthermore, the leading SPOD eigenvalues turn out to be, at least, two orders of magnitude larger than higher-order eigenvalues, suggesting potential of reduced-order models for the twin-jet screech.

description: Force chains, which are quasi-linear self-organised structures carrying large stresses, are ubiquitous in jammed amorphous materials, such as granular materials, foams, emulsions or even assemblies of cells. Predicting where they will form upon mechanical deformation is crucial in order to describe the physical properties of such materials, but remains an open question. Here we demonstrate that graph neural networks (GNN) can accurately infer the location of these force chains in frictionless materials from the local structure prior to deformation, without receiving any information about the inter-particle forces. Once trained on a prototypical system, the GNN prediction accuracy proves to be robust to changes in packing fraction, mixture composition, amount of deformation, and the form of the interaction potential. The GNN is also scalable, as it can make predictions for systems much larger than those it was trained on. Our results and methodology will be of interest for experimental realizations of granular matter and jammed disordered systems, e.g. in cases where direct visualisation of force chains is not possible or contact forces cannot be measured.

description: This paper presents the first topological analysis of the economic structure of an entire country based on payments data obtained from Swedbank. This data set is exclusive in its kind because around 80% of Estonia's bank transactions are done through Swedbank, hence, the economic structure of the country can be reconstructed. Scale-free networks are commonly observed in a wide array of different contexts such as nature and society. In this paper, the nodes are comprised by customers of the bank (legal entities) and the links are established by payments between these nodes. We study the scaling-free and structural properties of this network. We also describe its topology, components and behaviors. We show that this network shares typical structural characteristics known in other complex networks: degree distributions follow a power law, low clustering coefficient and low average shortest path length. We identify the key nodes of the network and perform simulations of resiliency against random and targeted attacks of the nodes with two different approaches. With this, we find that by identifying and studying the links between the nodes is possible to perform vulnerability analysis of the Estonian economy with respect to economic shocks.
