description: We have recently introduced a new model for the distribution of dark matter (DM) in galaxies based on a self-gravitating system of massive fermions at finite temperatures, the Ruffini-Argüelles-Rueda (RAR) model. We show that this model, for fermion masses in the keV range, explains the DM halo of the Galaxy and predicts the existence of a denser quantum core at the center. We demonstrate here that the introduction of a cutoff in the fermion phase-space distribution, necessary to account for the finite Galaxy size, defines a new solution with a central core which represents an alternative to the black hole (BH) scenario for SgrA*. For a fermion mass in the range $mc^2 = 48$ -- $345$~keV, the DM halo distribution is in agreement with the Milky Way rotation curve data, while harbors a dense quantum core of about $4\times10^6 M_\odot$ within the S2-star pericenter.

description: Weltausstellung und Nachhaltigkeit?Zwei sich auf den ersten Blick aufgrund ihrer höchst unterschiedlichen Zeitdimensionen widersprechende Aspekte bilden den Untersuchungsgegenstand der Forschungsarbeit. Kann eine zeitlich befristete Großveranstaltung einen Beitrag zu einer dauerhaften und zukunftsbeständigen Entwicklung leisten?Das Gegenteil scheint der Fall zu sein: Weltausstellungen wird zunächst unterstellt, dass sie reine Prestigeprojekte im Sinne der Städtekonkurrenz seien. Durch die Ausrichtung des halbjährigen Spektakels mit einem medienwirksamen Thema, so die Kritiker, haben die austragenden Städte doch hauptsächlich ökonomische Effekte im Blickfeld, beispielsweise durch Investitionsschübe, steigende Touristenzahlen, monetäre Gewinne und zusätzliche Steuereinnahmen.Auch das Thema Stadtentwicklung bleibt im Zusammenhang mit Weltausstellungen nicht unberührt. Großveranstaltungen wird unterstellt, dass sie Einrichtungen seien, mit denen Stadtentwicklungspolitik betrieben werde. Im Sinne der Festivalisierungsthese also: nicht Stadtpolitik für ein Festival, sondern Festivalisierung der Stadtentwicklung. Eine Projektentwicklung, die im Wesentlichen nicht an vorhandene städtebauliche Leitideen anknüpft, sondern in erster Linie auf den reibungslosen Ablauf der Großveranstaltung abzielt. Eine solche Intention kann jedoch nicht zeitgemäß sein für eine Weltausstellung Expo 2000, die sich medienwirksam am beginnenden 21. Jahrhundert präsentierte.Im Rahmen der Dissertation wird daher herausgearbeitet, ob der Expo-Planung in Hannover noch andere Leitvorstellungen zugrunde lagen. Gab es noch weitere Motive als die Bündelung der städtebaulichen Aktivitäten in einem zeitlich und räumlich begrenzten Prozess auf das ausschließliche Ziel der reibungslosen Durchführung einer Weltausstellung?
Da Großveranstaltungen kein Ersatz für die eigenständige Formulierung von städtebaulichen Zielen und Strategien sein können, ist es vor dem Hintergrund der Modernisierungstheorie interessant zu erkunden, ob der austragenden Stadt Hannover ein dauerhafter städtebaulicher Gewinn durch die realisierten Expo-Projekte bleibt. Fand ein Strukturwandel der Planungsmentalität statt; vielleicht auch Veränderungen innerhalb der Planungspolitik? Und werden die Erkenntnisse aus den Expo-Projekten als Lernerfolge in weitere Maßnahmen überführt?

description: An error-erasure channel is a simple noise model that introduces both errors and erasures. While the two types of errors can be corrected simultaneously with error-correcting codes, it is also known that any linear code allows for first correcting errors and then erasures in two-step decoding. In particular, a carefully designed parity-check matrix not only allows for separating erasures from errors but also makes it possible to efficiently correct erasures. The separating redundancy of a linear code is the number of parity-check equations in a smallest parity-check matrix that has the required property for this error-erasure separation. In a sense, it is a parameter of a linear code that represents the minimum overhead for efficiently separating erasures from errors. While several bounds on separating redundancy are known, there still remains a wide gap between upper and lower bounds except for a few limited cases. In this paper, using probabilistic combinatorics and design theory, we improve both upper and lower bounds on separating redundancy. We also show a relation between parity-check matrices for error-erasure separation and special matrices, called X-codes, for data compaction circuits in VLSI testing. This leads to an exponentially improved bound on the size of an optimal X-code.

description: Along with the oil price, concerns about the security of energy supply have soared once again in recent years. Yet, some 40 years after the OPEC oil embargo in 1973, there is no widely accepted statistical measure that captures the notion of energy security. Most likely, this deficit is the result of the great variety of resource economic aspects that are of potential relevance. This paper develops a statistical risk indicator that aims at characterizing the physical energy supply vulnerability of nations that are heavily dependent on energy imports. Our risk indicator condenses the empirical information on the imports of the whole range of fossil fuels, originating from a multitude of export countries, as well as data on their indigenous contribution to domestic energy supply, into a single figure. Applying the proposed concept to empirical energy data on Germany and the U.S. (1980-2007), we find that there is a large gap in the supply risks between both countries, with Germany suffering much more from a tight energy supply situation today than the U.S.

description: We compute meson scattering amplitudes using the holographic duality between confining gauge theories and string theory, in order to consider holographic corrections to the Veneziano amplitude and associated higher-point functions. The generic nature of such computations is explained, thanks to the well-understood nature of confining string backgrounds, and two different examples of the calculation in given backgrounds are used to illustrate the details. The effect we discover, whilst only qualitative, is re-obtainable in many such examples, in four-point but also higher point amplitudes.

description: An exact, closed form, and easy to compute expression for the mean integrated squared error (MISE) of a kernel estimator of a normal mixture cumulative distribution function is derived for the class of arbitrary order Gaussian-based kernels. Comparisons are made with MISE of the empirical distribution function, the infeasible minimum MISE of kernel estimators, and the asymptotically optimal second order uniform kernel. The results afford straightforward extensions to other classes of kernel functions and distributions. The analysis also offers a guide on when to use higher order kernels in distribution function estimation. A simple plug-in method of simultaneously selecting the optimal bandwidth and kernel order is proposed based on a non-asymptotic approximation of the unknown distribution by a normal mixture. A simulation study shows that the method works well in finite samples, thus providing a viable alternative to existing bandwidth selection procedures.

description: Many security and software testing applications require checking whether certain properties of a program hold for any possible usage scenario. For instance, a tool for identifying software vulnerabilities may need to rule out the existence of any backdoor to bypass a program's authentication. One approach would be to test the program using different, possibly random inputs. As the backdoor may only be hit for very specific program workloads, automated exploration of the space of possible inputs is of the essence. Symbolic execution provides an elegant solution to the problem, by systematically exploring many possible execution paths at the same time without necessarily requiring concrete inputs. Rather than taking on fully specified input values, the technique abstractly represents them as symbols, resorting to constraint solvers to construct actual instances that would cause property violations. Symbolic execution has been incubated in dozens of tools developed over the last four decades, leading to major practical breakthroughs in a number of prominent software reliability applications. The goal of this survey is to provide an overview of the main ideas, challenges, and solutions developed in the area, distilling them for a broad audience.

description: We consider a model ecosystem of sessile species competing for space. In particular, we consider the system introduced in [Mathiesen et al. Phys. Rev. Lett. 107, 188101 (2011)] where species compete according to a fixed interaction network with links determined by a Bernoulli process. In the limit of a small introduction rate of new species, the model exhibits a discontinuous transition from a high-diversity state to a low-diversity state as the interaction probability between species, $γ$, is increased from zero. Here we explore the effects of finite introduction rates and system-size on the phase transition by utilizing efficient parallel computing. We find that the low state appears for $γ>γ_c$. As $γ$ is increased further, the high state approaches to the low state, suggesting the possibility that the two states merge at a high $γ$. We find that the fraction of time spent in the high state becomes longer with higher introduction rates, but the availability of the two states is rather insensitive to the value of the introduction rate. Furthermore we establish a relation between the introduction rate and the system size, which preserves the probability for the system to remain in the high-diversity state.

description: The collective behavior of vibrated hexagonal disks confined in a monolayer is investigated experimentally. Due to the broken circular symmetry, hexagons prefer to rotate upon sufficiently strong driving. Due to the formation of liquid bridges, short-ranged cohesive interactions are introduced upon wetting. Consequently, a nonequilibrium stationary state with the rotating disks self-organized in a hexagonal structure arises. The bond length of the hexagonal structure is slightly smaller than the circumdiameter of a hexagon, indicating geometric frustration. This investigation provides an example where the collective behavior of granular matter is tuned by the shape of individual particles.

Title: An internal diaspora: opportunities for island repopulation?

Presenters:  Paula Duffy, Lorna Philip

Co-authors : Kirsten Gow, Mags Currie and Ruth Wilson

Abstract: 

Academic researchers and policy makers have had a long-standing interest in diaspora populations.  Reflecting an increasingly transnational lens, diaspora research has largely been international in scale, interested in expatriates and their descendants.  In this paper we propose that studies of internal diaspora groups represent an opportunity for advancing diaspora studies.  Across the world there has been long-term out-migration from island communities and associated island depopulation.  Islanders are often internal migrants who settle on the mainland, often in locations where other islanders have moved to in the past which creates opportunities for an islander identity to be sustained.  Sustained out-migration from Scotland’s numerous inhabited islands and associated islands depopulation has resulted in generations of islanders settling on the Scottish mainland and the creation of ‘island spaces’, notably in cities such as Glasgow, Edinburgh and Aberdeen.  Little is known about Scotland’s internal islands diaspora or whether members could contribute to achieving Strategic Objective 1 in the Scottish National Islands Plan, “address population decline and ensure a healthy, balanced population profile” (Scottish Government, 2019)?  We present findings from analysis of data collected via a questionnaire survey designed to map attributes of the Scottish islands diaspora to: (i) identify aspirations to return to live in an island; (ii) understand attributes of diaspora members who aspire and do not aspire to return to live in an island; and (iii) identify spatial patterns of return aspirations.  Combined, this analysis provides novel insights into the population potential of an island diaspora group.

description: Large margin nearest neighbor (LMNN) is a metric learner which optimizes the performance of the popular $k$NN classifier. However, its resulting metric relies on pre-selected target neighbors. In this paper, we address the feasibility of LMNN's optimization constraints regarding these target points, and introduce a mathematical measure to evaluate the size of the feasible region of the optimization problem. We enhance the optimization framework of LMNN by a weighting scheme which prefers data triplets which yield a larger feasible region. This increases the chances to obtain a good metric as the solution of LMNN's problem. We evaluate the performance of the resulting feasibility-based LMNN algorithm using synthetic and real datasets. The empirical results show an improved accuracy for different types of datasets in comparison to regular LMNN.

description: Observations of Pluto's surface made by the New Horizons spacecraft indicates present-day nitrogen ice glaciation in and around the basin known as Sputnik Planum. Motivated by these observations, we have developed an evolutionary glacial flow model of solid nitrogen ice taking into account its published thermophysical and rheologies properties. This model assumes that glacial ice layers flow laminarly and have low aspect ratios which permits a vertically integrated mathematical formulation. We assess the conditions for the validity of laminar nitrogen ice motion by revisiting the problem of the onset of solid-state buoyant convection of nitrogen ice for a variety of bottom thermal boundary conditions. Subject to uncertainties in nitrogen ice rheology, nitrogen ice layers are estimated to flow laminarly for thicknesses less than 400-1000 meters. The resulting mass-flux formulation for when the nitrogen ice flows as a laminar dry glacier is characterized by an Arrhenius-Glen functional form. The flow model developed is used here to qualitatively answer some questions motivated by observed glacial flow features found on Sputnik Planum. We find that the wavy transverse dark features found along the northern shoreline of Sputnik Planum may be a transitory imprint of shallow topography just beneath the ice surface suggesting the possibility that a major shoreward flow event happened relatively recently within the last few hundred years. Model results also support the interpretation that the prominent darkened features resembling flow lobes observed along the eastern shoreline of the Sputnik Planum basin may be a result of wet nitrogen glacial ice flowing into the basin from the pitted highlands of eastern Tombaugh Regio.

description: We theoretically study the magnetic properties of pyrochlore iridate bilayer and trilayer thin films grown along the $[111]$ direction using a strong coupling approach. We find the ground state magnetic configurations on a mean field level and carry out a spin-wave analysis about them. In the trilayer case the ground state is found to be the all-in-all-out (AIAO) state, whereas the bilayer has a deformed AIAO state. For all parameters of the spin-orbit coupled Hamiltonian we study, the lowest magnon band in the trilayer case has a nonzero Chern number. In the bilayer case we also find a parameter range with nonzero Chern numbers. We calculate the magnon Hall response for both geometries, finding a striking sign change as function of temperature. Using a slave-boson mean-field theory we study the doping of the trilayer system and discover an unconventional time-reversal symmetry broken $d+id$ superconducting state. Our study complements prior work in the weak coupling limit and suggests that the $[111]$ grown thin film pyrochlore iridates are a promising candidate for topological properties and unconventional orders.

Serious Games in Cultural Heritage: A Review of Practices and Considerations in the Design of Location-Based Games

Year: 2023
Subjects: Serious games

description: The overwhelming growth and popularity of mobile devices and games have motivated initiatives to explore mobile and augmented reality to bring the physical and virtual together. While several domains have been the recipient of such focus, particular importance has been placed on the cultural heritage (CH) field, with examples demonstrating the promise of location-based games (LBGs) at enhancing the CH experience aimed at promoting awareness. Games like Pokémon GO have exacerbated the appeal of LBGs, showing that they can be as popular as blockbuster video games. However, as much potential as LBGs have in raising CH awareness, they can be challenging to build because, unlike their commercial counterparts, their primary aim is learning, emphasizing the cultural significance of the real-world location rather than augmented assets. With limited research that explicitly identifies elements in creating these games in CH contexts, this work aimed to identify design practices and considerations in the design of LBGs. This work is intended for educators, researchers, instructional designers, game developers, and those in the CH field interested in exploring creative ways to embody a deeper understanding of and appreciation for CH.

description: We present the latest developments to the CheckMATE program that allows models of new physics to be easily tested against the recent LHC data. To achieve this goal, the core of CheckMATE now contains over 60 LHC analyses of which 12 are from the 13 TeV run. The main new feature is that CheckMATE 2 now integrates the Monte Carlo event generation via Madgraph and Pythia 8. This allows users to go directly from a SLHA file or UFO model to the result of whether a model is allowed or not. In addition, the integration of the event generation leads to a significant increase in the speed of the program. Many other improvements have also been made, including the possibility to now combine signal regions to give a total likelihood for a model.

description: The aim of this work is to combine the model of orbital and rotational motion of the Moon developed for DE430 with up-to-date astronomical, geodynamical, and geo- and selenophysical models. The parameters of the orbit and physical libration are determined in this work from LLR observations made at different observatories in 1970-2013. Parameters of other models are taken from solutions that were obtained independently from LLR. A new implementation of the DE430 lunar model, including the liquid core equations, was done within the EPM ephemeris. The postfit residuals of LLR observations make evident that the terrestrial models and solutions recommended by the IERS Conventions are compatible with the lunar theory. That includes: EGM2008 with conventional corrections and variations from solid and ocean tides; displacement of stations due to solid and ocean loading tides; and precession-nutation model. Usage of these models in the solution for LLR observations has allowed us to reduce the number of parameters to be fit. The fixed model of tidal variations of the geopotential has resulted in a lesser value of Moon's extra eccentricity rate, as compared to the original DE430 model with two fit parameters. A mixed model of lunar gravitational potential was used, with some coefficients determined from LLR observations, and other taken from the GL660b solution. Solutions obtain accurate positions for the ranging stations and the 5 retroreflectors. Station motion is derived for sites with long data spans. Dissipation is detected at the lunar fluid core-solid mantle boundary demonstrating that a fluid core is present. Tidal dissipation is strong at both Earth and Moon. Consequently, the lunar semimajor axis is expanding by 38.20 mm/yr, the tidal acceleration in mean longitude is -25.90 "/cy2, and the eccentricity is increasing by 1.48e-11 each year.

description: The AGN that define the radio Celestial Reference Frame (CRF) are not perfect stable point sources and are known to vary in both flux density and structure on timescales of months to years. The variations in structure can lead to significant errors in astrometric Very Long Baseline Interferometry (VLBI) measurements. Ideally, the effects of source structure should be accounted for in the VLBI analysis, but such modelling requires an ongoing imaging effort for all CRF sources.  Observing at 24 GHz, higher than the traditional-used frequencies below 10 GHz, allows for better resolution and astrometric accuracy.

description: Recently, virtual reality, augmented reality, robotics, autonomous driving et al attract much attention of both academic and industrial community, in which image based camera localization is a key task. However, there has not been a complete review on image-based camera localization. It is urgent to map this topic to help people enter the field quickly. In this paper, an overview of image based camera localization is presented. A new and complete kind of classifications for image based camera localization is provided and the related techniques are introduced. Trends for the future development are also discussed. It will be useful to not only researchers but also engineers and other people interested.

description: Abstract: Languages evolve naturally over time, reflecting cultural, social, and phonetic changes as they are spoken and written by different communities. Italian, like all Romance languages, evolved from Latin. While the focal point of this volume may appear to be on the word, espresso, it isn't. While 'espresso' is the global community standard, the correct historical, linguistic, and etymological spelling and pronunciation is actually "expresso." This reflects the word's true origins and the natural linguistic evolution that has shaped its current usage.

description: The rules and procedures regulating the admission of potentially unreliable expert evidence have been substantially weakened over the past several years. We respond to this trend by focusing on one aspect of the rules that has not been explicitly curtailed: unfair prejudice. Unfair prejudice is an important component of trial judges’ authority to exclude evidence, which they may do when that unfair prejudice outweighs the evidence’s probative value. We develop the concept of unfair prejudice by first examining how it has been interpreted by judges and then relating that to the relevant social scientific research on the characteristics of expertise that can make it prejudicial. In doing so, we also discuss the research behind a common reason that judges admit expert evidence despite its prejudice, which is that judicial directions help jurors understand and weigh it. As a result, this article provides two main contributions. First, it advances knowledge about unfair prejudice, which is an important part of expert evidence law that has received relatively little attention from legal researchers. Second, it provides guidance to practitioners for challenging expert evidence under one of the few avenues left to do so.

description: Crowd workers are distributed and decentralized. While decentralization is designed to utilize independent judgment to promote high-quality results, it paradoxically undercuts behaviors and institutions that are critical to high-quality work. Reputation is one central example: crowdsourcing systems depend on reputation scores from decentralized workers and requesters, but these scores are notoriously inflated and uninformative. In this paper, we draw inspiration from historical worker guilds (e.g., in the silk trade) to design and implement crowd guilds: centralized groups of crowd workers who collectively certify each other's quality through double-blind peer assessment. A two-week field experiment compared crowd guilds to a traditional decentralized crowd work model. Crowd guilds produced reputation signals more strongly correlated with ground-truth worker quality than signals available on current crowd working platforms, and more accurate than in the traditional model.

description: Presentation from 19th Acubed & Airbus Semantics Meetup, May 11th, 2023 Abstract: Scientists rely on biomedical knowledge bases such as the Gene Ontology in order to design experiments, predict outcomes, and interpret complex high-throughput molecular data. These knowledge bases contain complex assertions describing the contextual roles of genes in the functioning of cells and whole organisms. These assertions are acquired via painstaking curation from the biomedical literature. Automating the acquisition of these assertions is a hard problem requiring deep expertise to read and interpret scientific papers, and attempts to extract relationships via text mining have not reached a high enough level of accuracy to be deployed in production. Additionally, traditional text mining pipelines require extensive training data, and are typically not generalizable across different databases, or applicable in domains with complex semantic information models. The latest generation of Large Language Models (LLMs) such as GPT-3 and above have demonstrated exceptional general-purpose instruction following abilities, with a single model able to perform on a wide variety of tasks. However, these models lack grounding in knowledge bases, and are prone to hallucination. We have developed a framework called OntoGPT that brings together ontologies and LLMs. I will describe two tools that are part of OntoGPT (1) SPIRES, a tool for extracting semantic structures from text according to a user-specific knowledge schema specified using the LinkML framework, without training data. SPIRES is able to perform tasks such as scraping recipe websites to construct OWL ontologies grounded using classes from the Food Ontology, amenable to logical reasoning (2) SPINDOCTOR, a tool for interpreting genomics experiments. I will describe the strengths and limitations of LLMs for these applications, and potential avenues for future development.

description: Erfolgreiches Lernen von Mathematik erfordert Möglichkeiten, sich die inneren Zusammenhänge der mannigfaltigen Tatsachen erarbeiten zu können und "das Wesen der Mathematik, das besonders in ihren Beweismethoden zutage tritt" (Naas/Tutschke 1986, S. 3), kennenzulernen. Es ist "ein argumentatives Unterrichtsklima zu schaffen, in dem Begründungen mathematischer Aussagen und rationale Argumentationen selbstverständlich sind." (Reiss 2002, S. 30) In meinem Beitrag zeige ich damit zusammenhängende Probleme auf und unterbreite Vorschläge.
Digital-analog quantum simulation of generalized Dicke models with superconducting circuits

description: We propose a digital-analog quantum simulation of generalized Dicke models with superconducting circuits, including Fermi-Bose condensates, biased and pulsed Dicke models, for all regimes of light-matter coupling. We encode these classes of problems in a set of superconducting qubits coupled with a bosonic mode implemented by a transmission line resonator. Via digital-analog techniques, an efficient quantum simulation can be performed in state-of-the-art circuit quantum electrodynamics platforms, by suitable decomposition into analog qubit-bosonic blocks and collective single-qubit pulses through digital steps. Moreover, just a single global analog block would be needed during the whole protocol in most of the cases, superimposed with fast periodic pulses to rotate and detune the qubits. Therefore, a large number of digital steps may be attained with this approach, providing a reduced digital error. Additionally, the number of gates per digital step does not grow with the number of qubits, rendering the simulation efficient. This strategy paves the way for the scalable digital-analog quantum simulation of many-body dynamics involving bosonic modes and spin degrees of freedom with superconducting circuits.
