description: The purpose of this article is to present a general method to find limiting laws for some renormalized statistics on random permutations. The model considered here is Ewens sampling model, which generalizes uniform random permutations. We describe the asymptotic behavior of a large family of statistics, including the number of occurrences of any given dashed pattern. Our approach is based on the method of moments and relies on the following intuition: two events involving the images of different integers are almost independent.

description: In the last months, governments around the world have adopted public policies to promote large-scale vaccination, and covid certificates. Whether such measures are adequate or not has been largely debated. But why have such debates emerged? To this day, alternatives to centralized decision-making have been limitedly discussed. Here, I present how an online platform could help thousands of citizens express their needs (plurality), agree on common priorities (popular consensus), and pool resources to become the protagonists of a common project, like body cells coordinate in real time to preserve life. Building on the commons, on the free/libre and open-source movement (crowdsourcing), on short online events (hackathons), and on a method to coordinate large groups, I sketch how such a platform could help citizens build solidarity-driven solutions during three-day events.

description: Mallorca ist das beliebteste ausländische Reiseziel deutscher Urlauber und Urlauberinnen. Jedes Jahr fliegen fast fünf Millionen von ihnen auf die Balearische Insel. Die Corona-Pandemie hatte den Passagierflugverkehr aber praktisch zum Erliegen gebracht. Ab Juni 2020 starteten zwar wieder mehr Flüge nach Mallorca, jedoch schwankte das Sitzplatzangebot je nach Woche zwischen zehn und 86 Prozent des Niveaus von 2019. Der Wochenbericht zeigt, welche Corona-Maßnahmen den Flugverkehr zwischen Deutschland und Mallorca besonders beeinflusst haben. So haben lokale Beschränkungen wie Ausgangssperren oder Maskenpflicht im Freien ihn kaum beeinträchtigt. Infektionsraten zu veröffentlichen oder an Reisende öffentlich zu appellieren hatte ebenfalls kaum einen Effekt. Lediglich strenge Reisebeschränkungen wie Einreiseverbote und Quarantänevorschriften haben sich auf den Flugverkehr erheblich ausgewirkt. Die Politik kann also nur über solche Maßnahmen den Reiseverkehr effektiv steuern. Gleichzeitig zeigen erste Daten zu den Impfungen, dass diese die Effekte der Reisebeschränkungen deutlich abschwächen.

description: Das Berliner Musikinstrumenten-Museum, eine der weltweit ältesten und bedeutendsten Sammlungen seiner Art, hat wie viele andere Berliner Museen zahlreiche Kriegsverluste zu beklagen. Nach dem Ende des Zweiten Weltkriegs konnte nur etwa ein Viertel des ursprünglichen Bestands von insgesamt rund 4000 Objekten gesichert werden. 1992 gelangte das historische Akzessionsbuch glücklicherweise wieder in den Besitz des Musikinstrumenten-Museums. Zudem erhielt das Staatliche Institut für Musikforschung umfangreiches Schrift- und Archivgut seiner Vorgängerinstitutionen zurück. Mit Unterstützung durch die Beauftragte der Bundesregierung für Kultur und Medien sowie durch die Stiftung Preußischer Kulturbesitz konnten dann in den Jahren 2013 bis 2015 zahlreiche Quellen und umfangreiche historische Materialien ausgewertet sowie weitere Untersuchungen und eingehende Nachforschungen zu den Kriegsverlusten angestellt werden. Die Publikation der Kriegsverluste des Berliner Musikinstrumenten-Museums erfolgt in drei Bänden, welche neben der eingehenden Dokumentation der verloren gegangenen Objekte und deren Provenienzen zudem die Geschichte der Sammlung von 1888 bis 1945 nachzeichnet. Zahlreiche historische Manuskripte, Skizzen, Zeichnungen und Fotografien dienen der Identifikation des bis heute nicht auffindbaren Bestands. Die Autorschaft der drei Bände haben Christopher Li, Gabriele Groll und Heike Fricke übernommen; alle drei haben sich über Jahre hinweg intensiv und kenntnisreich mit dem Sammlungsbestand des Berliner Musikinstrumenten-Museums befasst. Ergänzend zur Druckfassung lassen sich im Rahmen der vorliegenden Online-Veröffentlichung alle Katalogeinträge und das gesamte ergänzende Bildmaterial bequem recherchieren und mit weiteren Datenbanken abgleichen.
$J/ψ$ Production by Magnetic Excitation of $η_c$

description: We compute the probability of $J/ψ$ production from the interaction between $η_c$ and the strong magnetic field generated in relativistic heavy ion collisions. The computation is first carried out in the heavy quark effective model, in which the M1 radiative transition is considered. Then we investigate the transition in the framework of non-relativistic heavy hadron chiral perturbation theory and show that the polarization of $J/ψ$ produced by this process is parallel to the direction of magnetic field and thus perpendicular to the reaction plane. The transition probability obtained in both approaches is of order $2\times 10^{-4}$.

description: The paper presents two mechanisms for designing an on-demand, reliable and efficient collection protocol for Wireless Sensor Networks. The former is the Bidirectional Link Quality Estimation, which allows nodes to easily and quickly compute the quality of a link between a pair of nodes. The latter, Hierarchical Range Sectoring, organizes sensors in different sectors based on their location within the network. Based on this organization, nodes from each sector are coordinated to transmit in specific periods of time to reduce the hidden terminal problem. To evaluate these two mechanisms, a protocol called HBCP (Hierarchical-Based Collection Protocol), that implements both mechanisms, has been implemented in TinyOS 2.1, and evaluated in a testbed using TelosB motes. The results show that the HBCP protocol is able to achieve a very high reliability, especially in large networks and in scenarios with bottlenecks.

description: Spontaneous symmetry breaking can lead to the formation of time crystals, as well as spatial crystals. Here we propose a space-time crystal of trapped ions and a method to realize it experimentally by confining ions in a ring-shaped trapping potential with a static magnetic field. The ions spontaneously form a spatial ring crystal due to Coulomb repulsion. This ion crystal can rotate persistently at the lowest quantum energy state in magnetic fields with fractional fluxes. The persistent rotation of trapped ions produces the temporal order, leading to the formation of a space-time crystal. We show that these space-time crystals are robust for direct experimental observation. We also study the effects of finite temperatures on the persistent rotation. The proposed space-time crystals of trapped ions provide a new dimension for exploring many-body physics and emerging properties of matter.

Flexible and efficient exploration of rated datasets
Creators: name: Kolloju, Naresh Kumar
Publisher: name: University of British Columbia
Year: 2013

description: As users increasingly rely on collaborative rating sites to achieve mundane tasks such as purchasing a product or renting a movie, they are facing the data deluge of ratings and reviews. Traditionally, the exploration of rated data sets has been enabled by rating averages that allow user-centric, itemcentric and top-k exploration. More speci cally, canned queries on user demographics aggregate opinion for an item or a collection of items such as 18-29 year old males in CA rated the movie The Social Network at 8:2 on average. Combining ratings, demographics, and item attributes is a powerful exploration mechanism that allows operations such as comparing the opinion of the same users for two items, comparing two groups of users on their opinion for a given class of items, and nding a group whose rating distribution is nearly unanimous for an item. To enable those operations, it is necessary to (i) adopt the right measure to compare ratings, and to (ii) develop e cient algorithms to nd relevant  groups. We argue that rating average is a weak measure for capturing such comparisons. We propose contrasting and querying rating distributions, instead, using the Earth Mover's Distance (EMD), a measure that intuitively re ects the amount of work needed to transform one distribution into another. We show that the problem of nding groups matching given rating distributions is NP-hard under di erent settings and develop appropriate heuristics. Our experiments on real and synthetic datasets validate the utility of our approach and demonstrate the scalability of our algorithms.

It combines symplectic groupoids, holomorphic Lie groupoids and holomorphic Poisson groupoids into a unified framework. Their infinitesimal, Glanon Lie algebroids are studied. We prove that there is a bijection between Glanon Lie algebroids and source-simply connected and source-connected Glanon groupoids. As a consequence, we recover various integration theorem and obtain the integration theorem for holomorphic Poisson groupoids.

Multi-site mean-field theory for cold bosonic atoms in optical lattices

description: We present a detailed derivation of a multi-site mean-field theory (MSMFT) used to describe the Mott-insulator to superfluid transition of bosonic atoms in optical lattices. The approach is based on partitioning the lattice into small clusters which are decoupled by means of a mean field approximation. This approximation invokes local superfluid order parameters defined for each of the boundary sites of the cluster. The resulting MSMFT grand potential has a non-trivial topology as a function of the various order parameters. An understanding of this topology provides two different criteria for the determination of the Mott insulator superfluid phase boundaries. We apply this formalism to $d$-dimensional hypercubic lattices in one, two and three dimensions, and demonstrate the improvement in the estimation of the phase boundaries when MSMFT is utilized for increasingly larger clusters, with the best quantitative agreement found for $d=3$. The MSMFT is then used to examine a linear dimer chain in which the on-site energies within the dimer have an energy separation of $Δ$. This system has a complicated phase diagram within the parameter space of the model, with many distinct Mott phases separated by superfluid regions.

description: Exploiting a fundamental characteristic of galaxy assembly in the ΛCDM paradigm, the observed spatial biasing and kinematics of metal-poor globular star clusters are used to constrain the local reionization epoch around individual galaxies. Selecting three galaxies located in different environments, the first attempt at constraining the environmental propagation of reionization in the local Universe is carried out. The joint constraint from the three galaxies (z_reion = 10.5^{+1.0}_{-0.9}) agrees remarkably well with the latest WMAP constraint on z_reion for a simple instantaneous reionization model. More importantly, the range of z_reion values found here are consistent with the global range of z_reion estimates from other observations. We furthermore find a 1.7σ indication that reionization completed in low-density environments before the intergalactic medium in high-density environments was reionized. This is consistent with certain theoretical models that predict that reionization was globally prolonged in duration, with neutral hydrogen pockets surviving in high-density environments, even after the surrounding regions were reionized. More generally, this work provides a useful constraint on the formation history of galaxy stellar halos.

description: As part of the Panama Canal Treaties of 1977, the United States turned over to the Government of the Republic of Panama on Dec. 31, 1999, its control of the Panama Canal, which it financed, built, and maintained. U.S. agricultural shipments are cargoes important to the canal. In 1998, they made up more than one-fifth of the canal cargo volume, more than two-thirds of all agricultural shipments, and more than half of the U.S. cargo volume transported through the canal. The canal is also important to U.S. producers of corn and soybeans in that it gives them an efficient and effective transport route to foreign markets. Without the canal, it is estimated that U.S. exports of corn and soybeans could be 2 percent lower, which would lower producer revenues by $303.6 million. This report addresses how the Panama Canal transition to Panamanian control will affect U.S. agriculture.

description: Ramsey theory is a highly active research area in mathematics that studies the emergence of order in large disordered structures. Ramsey numbers mark the threshold at which order first appears and are extremely difficult to calculate due to their explosive rate of growth. Recently, an algorithm that can be implemented using adiabatic quantum evolution has been proposed that calculates the two-color Ramsey numbers $R(m,n)$. Here we present results of an experimental implementation of this algorithm and show that it correctly determines the Ramsey numbers R(3,3) and $R(m,2)$ for $4\leq m\leq 8$. The R(8,2) computation used 84 qubits of which 28 were computational qubits. This computation is the largest experimental implementation of a scientifically meaningful adiabatic evolution algorithm that has been done to date.

Acceleration of particles by black holes as a result of deceleration: ultimate manifestation of kinematic nature of BSW effect

description: The recently discovered so-called BSW effect consists in the unbound growth of the energy E_{c.m.} in the centre of mass frame of two colliding particles near the black hole horizon. We consider a new type of the corresponding scenario when one of two particles ("critical") remains at rest near the horizon of the charged near-extremal black hole due to balance between the attractive and repulsion forces. The other one hits it with a speed close to that of light. This scenario shows in a most pronounced way the kinematic nature of the BSW effect. In the extremal limit, one would gain formally infinite E_{c.m.} but this does not happen since it would have require the critical massive particle to remain at rest on the null horizon surface that is impossible. We also discuss the BSW effect in the metric of the extremal Reissner-Nordström black hole when the critical particle remains at rest near the horizon.

description: Die OECD empfiehlt die Implementierung nationaler Strategien für finanzielle Bildung. Auch viele weitere Länder, wie China und Indien, verfügen inzwischen über entsprechende Strategien, nicht hingegen Deutschland. Der stärkste Grund für eine ablehnende Haltung ist die Hypothese mangelnder Wirksamkeit von finanziellen Bildungsinterventionen. Diese Hypothese wird hier anhand aller verfügbaren, randomisierten Experimentalstudien untersucht und eindeutig abgelehnt. Finanzielle Bildungsinterventionen sind im Durchschnitt signifikant wirksam und das Ausmaß ist ähnlich zu vergleichbaren (Bildungs-)Interventionen. Dies schließt die Möglichkeit ein, dass einzelne Interventionen auch scheitern können; allerdings handelt es sich dabei um Ausnahmen. Finanzielle Bildung wirkt auch, wenn sie von kurzer Dauer ist, wenn ihre Wirksamkeit erst nach mehr als einem Jahr überprüft wird, wenn die Umstände schwierig sind und die Vermittlungsansätze konventionell bleiben. Das Argument der fehlenden Wirksamkeit ist daher entkräftet und die Politik kann vor diesem Hintergrund die OECD-Empfehlungen umsetzen.

We analyze the effects of this geometry on the backscattering current as a function of voltage, temperature, and strength of the electron interactions. We find that this configuration may be useful to confirm the helical nature of the edge states and to extract their propagation velocity. By comparing with the usual quantum point contact geometry, we observe that the power-law behaviors predicted for the backscattering current and the linear conductance are recovered for low enough energies, while different power-laws also emerge at higher energies.

description: During the course of the Magnetism in Massive Stars (MiMeS) Large Programs from 2009-13 over 550 Galactic B- and O-type stars were observed using high resolution spectropolarimeters in order to characterize the population of hot magnetic stars. Recent careful examination of the large sample of "normal" (i.e. non-Be, non-supergiant) B-type stars observed in the survey has revealed two additional magnetic stars. HD 221218 is an apparently single late-B-type main sequence star hosting a very strong magnetic field (Bz~2 kG) with a rotation period of about 2.6 d. HD 155273 appears to be mid-B-type SB2, in which the broader-lined secondary hosts a field of strength Bz~0.2 kG. In this presentation we provide a brief description of the analysis and modelling of the data, and the results of our detailed characterization of these interesting systems.

Biomechanical simulation of the hand musculoskeletal system and skin
Creators: name: Li, Duo
Publisher: name: University of British Columbia
Year: 2014

description: This thesis presents a biomechanically based hand simulator. We make contributions at two di erent levels: hand motion and hand appearance. We rst develop a musculotendon simulator, and apply this simulator to an anatomically based hand model. Anatomically based hand simulation is challenging because the tendon network of the hand is complicated and it is highly constrained by the skeleton of the hand. Our simulator employs the elegance of the Eulerian-Lagrangian strand algorithm, and introduces a 2D planar collision approach to e ciently eliminate unnecessary degrees of freedom and constraints. We show that with our method, we obtain the coupling between joints automatically, and achieve the storage of energy in tendons for fast movements. Also, by injuring a tendon, we are able to obtain simulations of common nger deformities. Although the musculotendon based hand simulation produces natural hand motion, hand animation is usually observed at the skin level. We present a novel approach to simulate thin hyperelastic skin. Real human skin is a thin tissue which can stretch and slide over underlying body structures such as muscles, bones, and tendons, revealing rich details of a moving character. Simulating such skin is challenging because it is in close contact with the body and shares its geometry. We propose a novel Eulerian representation of skin that avoids all the di culties of constraining the skin to lie on the body surface by working directly on the surface itself. Skin is modeled as a 2D hyperelastic membrane with arbitrary topology, which makes it easy to cover an entire character or object. We use triangular meshes to model body and skin geometry. The method is easy to implement, and can use low resolution meshes to animate high resolution details stored in texture-like maps. Skin movement is driven by the animation of body shape prescribed by an artist or by another simulation, and so it can be easily added as a post-processing stage to an existing animation pipeline. We demonstrate realistic animations of the skin on the hand using this approach. We also extend it to simulate other parts of human and animal skin, and skin-tight clothes.

description: We show that the Nambu-Goto string, and its higher dimensional generalizations, can be quantized, in the sense of an effective theory, in any dimension of the target space. The crucial point is to consider expansions around classical string configurations. We are using tools from perturbative algebraic quantum field theory, quantum field theory on curved spacetimes, and the Batalin-Vilkovisky formalism. Our model has some similarities with the Lüscher-Weisz string, but we allow for arbitrary classical background string configurations and keep the diffeomorphism invariance.

Thermal and chemical changes in planet-forming environments in numerical simulations, a possible new path for planet-hunting with ALMA
Creators: name: Alarcón, Felipe
Publisher: name: Zenodo
Year: 2023

description: Over the past few years, multiple protoplanets have been confirmed through direct imaging, and many other new candidates through indirect method detections such as gas kinematics with ALMA. In the planet-formation scenario with multiple planet candidates, we study the effect of accretion shocks and protoplanet thermal emission on its host disk and the surrounding planet-feeding\planet-seed material. We show the thermal changes of protoplanetary emission change the local emission from those planets. We also show its consequences and expectations for ALMA observations. In our analysis, we show the protoplanetary effect on gas composition and ALMA-relevant observables for different accretion rates and dust-to-gas ratios. Depending on the assumed regime, there will be footprints in the dust continuum emission from planet-hosting disks, along with chemical/thermal predicted signatures in line emission. The results have the potential to open new avenues for protoplanet detection through the scrapping of the rich ALMA archive and for the design of new proposed ALMA observations.

description: Die deutsche Wirtschaft lässt die Pandemie langsamer als erwartet hinter sich. Sie legt wohl in diesem Jahr lediglich um 2,1 Prozent zu; die Kapazitäten bleiben noch deutlich unterausgelastet. Die globalen Lieferengpässe treffen die deutsche Industrie. Dadurch ist die heimische Produktion trotz hoher Nachfrage ins Stocken geraten. Auch die Dienstleistungsbranche schwächelt mit steigenden Infektionszahlen wieder, nachdem sie im Sommer von der zwischenzeitlich beruhigten Infektionslage und dem Impffortschritt noch profitierte. Wenn sich die Lieferengpässe im kommenden Jahr auflösen, dürfte die Industrie durchstarten und die deutsche Wirtschaft ein kräftiges Plus von 4,9 Prozent verzeichnen. Die Inflation bleibt in der Grundtendenz moderat, in diesem Jahr treiben jedoch insbesondere die gestiegenen Ölpreise und die Rückkehr zur normalen Mehrwertsteuer die Rate auf 3,0 Prozent. Diese Effekte entfallen im kommenden Jahr. Dennoch wird die Inflation bei rund 2,0 Prozent etwas erhöht bleiben, da die Unternehmen die aufgrund der knappen Vorleistungen steigenden Produktionskosten teilweise weiterreichen.

description: Report Introduction: The inland waterways system facilitates a strong U.S. economy, providing safe, cost-effective and environmentally friendly transportation of agricultural products and other goods, such as coal, petroleum and chemicals, for export and import and for domestic consumption. Informa’s Agribusiness Consulting has been retained by the U.S. Department of Agriculture, Agricultural Marketing Service to document and quantify the importance of the waterways system to the U.S. economy, specifically to U.S. agriculture. U.S. agriculture depends on an efficient and reliable infrastructure system to move grains, soybeans, and other products to the global market place. The United States has been the envy of the world with a robust and expansive transportation infrastructure. However, that infrastructure has aged over time. An aging and less reliable inland waterways infrastructure has resulted in lower effective transportation capacity. That lower capacity leads to higher freight rates for other modes. Those higher freight rates decrease farmer returns, leading to lower economic activity. Finally, without infrastructure investment, the farmer and the agribusiness sector are less competitive globally. Thus, to be competitive in the global marketplace, the U.S. farmer and U.S. agriculture need a reliable transportation infrastructure system, including a well-functioning inland waterways system.

description: Die Pandemie ließ die konjunkturellen Entwicklungen großer Ökonomien zuletzt auseinanderdriften. Einem im zweiten Quartal abklingenden Infektionsgeschehen etwa in Europa oder den USA verbunden mit kräftigen Produktionszuwächsen standen in Schwellenländern harte wirtschaftliche Einschränkungen aufgrund hoher Corona-Fallzahlen gegenüber. Dort entwickelte sich die Wirtschaft zum Teil rückläufig. Global hat sich das Infektionsgeschehen im Spätsommer deutlich entschleunigt. Die Weltwirtschaft dürfte ab dem dritten Quartal wieder auf Erholungskurs kommen. Zwar sind im Winter wieder steigende Infektionsinzidenzen zu erwarten, allerdings werden diese durch einen erhöhten Impfschutz der Bevölkerung zusammen mit punktuell eingesetzten Eindämmungsmaßnahmen die Wirtschaft vermutlich weit weniger belasten als zuvor. Für positive Impulse insbesondere bei den Dienstleistungen sorgen vor allem weiterhin kräftige Zuwächse im privaten Verbrauch, die auch in den kommenden Jahren ein zentraler Wachstumstreiber bleiben dürften. Zwar dämpfen zurzeit Rohstoff- und Inputknappheiten insbesondere das verarbeitende Gewerbe. Die Störungen internationaler Lieferketten und Einschränkungen an wichtigen Standorten für die Vorproduktherstellung dürften sich allerdings im ersten Halbjahr 2022 wieder auflösen. Dies wird wohl zu einigen Aufholeffekten im verarbeitenden Gewerbe führen, was der Weltwirtschaft zusätzlichen Schwung verleihen dürfte. So hält das DIW Berlin für dieses Jahr an seiner Wachstumsprognose für die Weltwirtschaft von 6,7 Prozent fest. 2022 dürfte die globale Wirtschaftsleistung um 5,2 Prozent zulegen. Vor einem Vierteljahr lag die Erwartung noch um 0,3 Prozentpunkte niedriger. 2023 ist dann mit einem Wachstum von 4,2 Prozent zu rechnen.

description: We construct analytic solutions of open superstring field theory in the Berkovits formulation using boundary condition changing operators under some regularity conditions, extending the previous construction in the bosonic string. We also consider the gauge-invariant observables corresponding to closed string one-point functions on the disk. We analytically calculate the gauge-invariant observables for the solutions both in the bosonic string and in the superstring and find the expected change of boundary conditions of the disk.
