description: Robust low-level image features have been proven to be effective representations for a variety of visual recognition tasks such as object recognition and scene classification; but pixels, or even local image patches, carry little semantic meanings. For high level visual tasks, such low-level image representations are potentially not enough. In this paper, we propose a high-level image representation, called the Object Bank, where an image is represented as a scale-invariant response map of a large number of pre-trained generic object detectors, blind to the testing dataset or visual task. Leveraging on the Object Bank representation, superior performances on high level visual recognition tasks can be achieved with simple off-the-shelf classifiers such as logistic regression and linear SVM. Sparsity algorithms make our representation more efficient and scalable for large scene datasets, and reveal semantically meaningful feature patterns.

description: Theia is a proposed multi-kiloton scale advanced optical neutrino detector with a broad range of physics goals. By employing water-based liquid scintillator (WbLS) or a similar technology, Theia will be able to harness the high light yield of liquid scintillator detectors with the direction reconstruction capability of water Cherenkov detectors. One physics goal is to leverage these capabilities to study the as-yet-undetected CNO neutrino flux, in order to help resolve uncertainties regarding solar metallicity. In this poster, we discuss the physics potential for measurement of the CNO flux in various possible Theia detector configurations, considering different sizes, targets, angular resolutions, background levels and more. We show sensitivity to the flux normalization at the several percent-level for a range of configurations. We also discuss other potential opportunities for solar neutrino physics in Theia.

description: Food waste presents a substantial challenge with significant environmental and economic ramifications, and its severity on campus environments is of particular concern. In response to this, we introduce FoodWise, a dual-component system tailored to inspire and incentivize campus communities to reduce food waste. The system consists of a data storytelling dashboard that graphically displays food waste information from university canteens, coupled with a mobile web application that encourages users to log their food waste reduction actions and rewards active participants for their efforts. Deployed during a two-week food-saving campaign at The Hong Kong University of Science and Technology (HKUST) in March 2023, FoodWise engaged over 200 participants from the university community, resulting in the logging of over 800 daily food-saving actions. Feedback collected post-campaign underscores the system's efficacy in elevating user consciousness about food waste and prompting behavioral shifts towards a more sustainable campus. This paper also provides insights for enhancing our system, contributing to a broader discourse on sustainable campus initiatives.

description: Automatic translation tools have facilitated navigating multilingual contexts, by providing accessible shortcuts for gathering, processing, and spreading information. As language technologies become more widely used and deployed on a large scale, however, their societal impact has sparked concern both within and outside the research community. This thesis adresses gender bias affecting Machine Translation (MT) and Speech Translation (ST) models. It contributes to this pressing area of research with an interdisciplinary perspective, to raise awareness of bias, improve the understanding of the phenomenon, and investigate best practices and methods to unveil and mitigate it in translation systems.

description: The emergence of robo-advisors (RAs) raises crucial questions revolving around the balance of human intervention and machine component in wealth management, calling for a deeper understanding of a model where human and machine coexist. This paper focuses on the impact of automation and AI on the shifting role of financial advisors. Through a systematic literature review, it aids understanding how RAs are defined, how they are evolving, and how they interact with human financial advisors. Findings show that a consensus as to whether RAs will replace human financial advisors or not does not yet exist. Based on the literature review, we suggest a conceptual framework with two possible strategies for human-robot-coexistence in wealth management and a future research agenda. To successfully implement RAs into the workplace, we call for a deeper understanding of how organisations can help to adapt their workforce to accommodate automation technologies.

description: NOvA is a long-baseline neutrino oscillation experiment based at Fermilab, Illinois, sampling the NuMI neutrino beam at two functionally-identical detectors. The NOvA Test Beam program consists of a third, scaled-down detector placed in a charged particle beam, and aims to provide an improved understanding of the detector response and energy calibration to enable higher precision measurements of the neutrino oscillation parameters. As part of this program, a new beamline was deployed, derived from 120 GeV protons accelerated by Fermilab's Main Injector. This tertiary beamline provides 0.2—2 GeV/c charged particles sampled by the NOvA detector. It includes an analyzer magnet, time-of-flight system, and tracking using multi-wire proportional chambers, providing particle identification and precise momentum determination of the particles. This poster will discuss the design and performance of the beamline and show results from the first 4 months of data taking.

description: Three bodies moving in a periodic orbit under the influence of Newtonian gravity ought to emit gravitational waves. We have calculated the gravitational radiation quadrupolar waveforms and the corresponding luminosities for the 13+11 recently discovered three-body periodic orbits in Newtonian gravity. These waves clearly allow one to distinguish between their sources: all 13+11 orbits have different waveforms and their luminosities (evaluated at the same orbit energy and body mass) vary by up to 13 orders of magnitude in the mean, and up to 20 orders of magnitude for the peak values.

description: We propose an (optimal) estimator for a CMB bispectrum containing logarithmically spaced oscillations. There is tremendous theoretical interest in such bispectra, and they are predicted by a plethora of models, including axion monodromy models of inflation and initial state modifications. The number of resolved logarithmical oscillations in the bispectrum is limited due to the discrete resolution of the multipole bispectrum. We derive a simple relation between the maximum number of resolved oscillations and the frequency. We investigate several ways to factorize the primordial bispectrum, and conclude that a one dimensional expansion in the sum of the momenta $\sum k_i = k_t$ is the most efficient and flexible approach. We compare the expansion to the exact result in multipole space and show for $ω_{\rm eff}=100$ that $\mathcal{O}(10^3)$ modes are sufficient for an accurate reconstruction. We compute the expected $σ_{f_{\rm NL}}$ and find that within an effective field theory (EFT) the overall signal to noise scales as $S/N\propto ω^{3/2}$. Using only the temperature data we find $S/N\sim\mathcal{O}(1-10^2)$ for the frequency domain set by the EFT.

description: Real-time unusual event detection in video stream has been a difficult challenge due to the lack of sufficient training information, volatility of the definitions for both normality and abnormality, time constraints, and statistical limitation of the fitness of any parametric models. We propose a fully unsupervised dynamic sparse coding approach for detecting unusual events in videos based on online sparse re-constructibility of query signals from an atomically learned event dictionary, which forms a sparse coding bases. Based on an intuition that usual events in a video are more likely to be reconstructible from an event dictionary, whereas unusual events are not, our algorithm employs a principled convex optimization formulation that allows both a sparse reconstruction code, and an online dictionary to be jointly inferred and updated. Our algorithm is completely un-supervised, making no prior assumptions of what unusual events may look like and the settings of the cameras. The fact that the bases dictionary is updated in an online fashion as the algorithm observes more data, avoids any issues with concept drift. Experimental results on hours of real world surveillance video and several Youtube videos show that the proposed algorithm could reliably locate the unusual events in the video sequence, outperforming the current state-of-the-art methods.
title: Wohnen in Siedlungen der Protoindustrialisierung des 18. Jh. am Beispiel der Nadelburg in Lichtenwörth bei Wiener Neustadt
Creators: name: Harm, Nina
Year: 2023

description: Die Nadelburger Arbeitersiedlung stellt zu ihrer Entstehungszeit in der Mitte des 18. Jahrhunderts ein Novum auf österreichischem Boden dar: Erstmals ist eine einheitlich geplante, als auch errichteten Siedlung für die Arbeiterschaft einer spezifischen Fabrikanlage fassbar, die zugleich den Versuch darstellte eine Form des Wohnens für die sich neuformierende Bevölkerungsschicht der „Arbeiter“ zu etablieren. Es entstanden Häuser, deren äußeres Erscheinungsbild zwar vertraut auf die lokale Bevölkerung wirken mussten (sie entsprechen dem typisch ostösterreichischen Gebäudetypus des Streckhofes) jedoch zugleich eine Binnengliederung aufweisen, die auf die notwendigsten Funktionen des Wohnens reduziert wurden: Eine geteilte Küche für zwei Familien im Zentrum der Wohneinheit und jeweils ein einziges zusätzliches Zimmer für alle anderen alltäglichen Bedürfnisse. Ausgehend des zur Verfügung stehenden Quellmaterials, historischen Abbildungen und Planmaterials, untersucht diese Arbeit zunächst die Gründungsumstände der Siedlung, um schließlich eine architekturhistorische Einordung der Arbeitersiedlung als Ganzes und die Konzeption der einzelnen Häuser betreffend, vorzunehmen.
description: The Nadelburg housing settlement for the working class was a novelty on Austrian soil at the time it was built in the middle of the 18th century: For the first time, a uniformly planned and build settlement for the workers of a specific factory complex can be identified, which at the same time represented an attempt to establish a model of housing for the newly forming class of "workers". Houses were built whose external appearance had to be familiar to the local population of the nearby settlement (they visually corresponded to the rural eastern Austrian building type of the so called Streckhof), but at the same time the houses had an internal structure that was reduced to the most necessary functions of living: A shared kitchen for two families in the center of each housing unit and only a single additional room for all other daily needs one household got. Based on the available historical source material, figures and photographs, this work first examines the founding circumstances of the settlement, to finally undertake an architectural-historical classification of the workers' settlement, as well as investigate the configuration of the individual houses as a contemporary architectural phenomenon.

description: Purpose: Cone-beam CT (CBCT) projection images provide anatomical data in real-time over several respiratory cycles, forming a comprehensive picture of tumor movement. We developed and validated a method which uses these projections to determine the trajectory of and dose to highly mobile tumors during each fraction of treatment. Methods: CBCT images of a respiration phantom were acquired, the trajectory of which mimicked a lung tumor with high amplitude (up to 2.5 cm) and hysteresis. A template-matching algorithm was used to identify the location of a steel BB in each CBCT projection, and a Gaussian probability density function for the absolute BB position was calculated which best fit the observed trajectory of the BB in the imager geometry. Two modifications of the trajectory reconstruction were investigated: first, using respiratory phase information to refine the trajectory estimation (Phase), and second, using the Monte Carlo (MC) method to sample the estimated Gaussian tumor position distribution. Results: With all methods, the mean position of the BB was determined with accuracy better than 0.1 mm, and trajectory errors averaged 3.8$\pm$1.1% of the marker amplitude. Dosimetric calculations using Phase methods were more accurate, with mean absolute error less than 0.5%, and with error less than 1% in the highest-noise trajectory. MC-based trajectories prevent the over-estimation of dose, but when viewed in an absolute sense, add a small amount of dosimetric error (<0.1%). Conclusions: Marker trajectory and target dose-of-the-day were accurately calculated using CBCT projections. This technique provides a method to evaluate highly-mobile tumors using ordinary CBCT data, and could facilitate better strategies to mitigate or compensate for motion during SBRT.

description: In this paper, we explore salient questions about user interests, conversations and friendships in the Facebook social network, using a novel latent space model that integrates several data types. A key challenge of studying Facebook’s data is the wide range of data modalities such as text, network links, and categorical labels. Our latent space model seamlessly combines all three data modalities over millions of users, allowing us to study the interplay between user friendships, interests, and higher-order network-wide social trends on Facebook. The recovered insights not only answer our initial questions, but also reveal surprising facts about user interests in the context of Facebook’s ecosystem. We also confirm that our results are significant with respect to evidential information from the study subjects.

description: The ecosystem concept has gained increased attention in strategy, innovation, entrepreneurship, and marketing literature. Yet there is little understanding of how ecosystems emerge and their specific processes, mechanisms, and outputs. Firms need to better understand the ecosystem emergence dynamics to decide the ecosystem strategies they need to pursue. We conducted a systematic literature review on ecosystem emergence comprising 120 articles across management disciplines to address this gap. The paper contributes to the literature on strategy and innovation by highlighting the differences and similarities of structure, processes, and outputs across strategy and innovation, entrepreneurship and regional development and marketing. We also observe two different perspectives on entrepreneurial ecosystems in terms of output. An integrated view to examine the ecosystem emergence is proposed by highlighting the research gaps.

description: The combination of S-matrix unitarity and the dynamics of thermal freeze-out for massive relic particles (denoted here simply by WIMPs) implies a lower limit on the density of such particles, that provide a (potentially sub-dominant) contribution to dark matter. This then translates to lower limits to the signal rates for a variety of techniques for direct and indirect detection of dark matter. For illustration, we focus on models where annihilation is s-wave dominated. We derive lower limits to the flux of gamma-rays from WIMP annihilation at the Galactic center; direct detection of WIMPs; energetic neutrinos from WIMP annihilation in the Sun; and the effects of WIMPs on the angular power spectrum and frequency spectrum of the cosmic microwave background radiation. The results suggest that a variety of dark-matter-search techniques may provide interesting avenues to seek new physics, even if WIMPs do not constitute all the dark matter. While the limits are quantitatively some distance from the reach of current measurements, they may be interesting for long-range planning exercises.

Critical Approach to L2 Classroom Discourse Competence

Publisher: name: PraxisForschungLehrer*innenBildung. Zeitschrift für Schul- und Professionsentwicklung.
Year: 2023

description: This article develops a proposal for a Critical Second Language (L2) Classroom Discourse Competence (CDC) for (English) language teachers. The proposal takes the comprehensive competence model as a starting point which Thomson (2022) presents in her volume on Classroom Discourse Competence, and argues that the existing model is highly valuable yet lacking in two aspects: 1) It does not yet consider the interconnectedness of classroom discourse with discourses outside the classroom. 2) In its focus on L2 acquisition (in the sense of language structures), it neglects the fact that another key task of 21st-century L2 teaching is fostering inclusion and, hence, social justice in and beyond the classroom. Consequently, this contribution argues that today’s L2 teachers’ classroom performance should not only provide a model of language structures, but also of inclusive and empowering discourse practices. To provide such a model, L2 teachers need a Critical L2 CDC. Hence, this article proposes to add knowledge, skills, and awareness elements to Thomson’s L2 CDC model, turning it into a Critical L2 CDC model. These considerations are specified by a multimodal interaction analysis of classroom videos from (inclusive) English lessons (years 5, 6, 9) that employ learner-centred methods. This analysis reveals the use of power-asymmetrical turn-taking practices and a potentially exclusive use of gender categories for classroom management. The article concludes by pointing out the potential role of teacher education in fostering Critical L2 CDC.

description: Massive MIMO and small cell are both recognized as the key technologies for the future 5G wireless systems. In this paper, we investigate the problem of user association in a heterogeneous network (HetNet) with massive MIMO and small cells, where the macro base station (BS) is equipped with a massive MIMO and the picocell BS's are equipped with regular MIMOs. We first develop centralized user association algorithms with proven optimality, considering various objectives such as rate maximization, proportional fairness, and joint user association and resource allocation. We then model the massive MIMO HetNet as a repeated game, which leads to distributed user association algorithms with proven convergence to the Nash Equilibrium (NE). We demonstrate the efficacy of these optimal schemes by comparison with several greedy algorithms through simulations.

description: In this paper, we address a challenging image segmentation problem called multiple foreground cosegmentation (MFC), which concerns a realistic scenario in general Webuser photo sets where a finite number of K foregrounds of interest repeatedly occur cross the entire photo set, but only an unknown subset of them is presented in each image. This contrasts the classical cosegmentation problem dealt with by most existing algorithms, which assume a much simpler but less realistic setting where the same set of foregrounds recurs in every image. We propose a novel optimization method for MFC, which makes no assumption on foreground configurations and does not suffer from the aforementioned limitation, while still leverages all the benefits of having co-occurring or (partially) recurring contents across images. Our method builds on an iterative scheme that alternates between a foreground modeling module and a region assignment module, both highly efficient and scalable. In particular, our approach is flexible enough to integrate any advanced region classifiers for foreground modeling, and our region assignment employs a combinatorial auction framework that enjoys several intuitively good properties such as optimality guarantee and linear complexity. We show the superior performance of our method in both segmentation quality and scalability in comparison with other state-of-the-art techniques on a newly introduced FlickrMFC dataset and the standard ImageNet dataset.

description: Rapidity dependent strangeness enhancement factors for the identified particles have been studied with the help of a string based hadronic transport model UrQMD-3.3 (Ultra-relativistic Quantum Molecular Dynamics) at FAIR energies. A strong rapidity dependent strangeness enhancement could be observed with our generated data for $Au + Au$ collisions at the beam energy of 30\textit{A} GeV. The strangeness enhancement is found to be maximum at mid-rapidity for the particles containing leading quarks while for particles consisting of produced quarks only, the situation is seen to be otherwise. Such rapidity dependent strangeness enhancement could be traced back to the dependence of rapidity width on centrality or otherwise on the distribution of net-baryon density.

description: Der Beitrag nimmt den unsichtbaren Kanon der Vergleichsdokumente des Lateinunterrichts in den Blick und unterzieht ihn exemplarisch an Cesare Maccaris Bild „Cicero klagt Catilina an“ einer Kritik. Auf dieser Basis werden zwei nicht-europäische Vergleichsdokumente – eines aus dem nordamerikanischen Westen, eines aus dem chinesischen Fernen Osten – unter dem Gesichtspunkt ihrer Eignung für den altsprachlichen Unterricht betrachtet. Die Vorschläge antworten dabei nicht zuletzt auf die Kritik des US-amerikanischen Altertumswissenschaftlers Dan-el Padilla Peralta an latent rassistischen Grundstrukturen in seiner Disziplin. Diese Kritik hat in den USA eine schon lange schwelende Debatte befeuert, in deren Rahmen auch der klassische Lektürekanon in Frage gestellt wurde. Gegenüber einer problematischen Lösung, den Textkanon der alten Sprachen aufzulösen, das in Hinblick auf muttersprachliche Texte als abgeschlossen gelten muss, wird der Vorschlag unterbreitet, den unsichtbaren Kanon der Vergleichsdokumente nach West und Ost zu öffnen. Der Beitrag illustriert diesen Vorschlag an jeweils einem Beispiel, wobei das erste, die Mythenrezeption der ersten afroamerikanischen Schriftstellerin Phillis Wheatley (1753?–1784), näher ausgeführt wird. Betrachtet wird konkret ihre poetische Rezeption des Niobe-Mythos der Metamorphosen Ovids und eines Gemälde Richard Wilsons, welche sich als Reflex biographischer Erfahrungen im Code der ovidischen und wilsonschen poetischen Welt zeigt. Ein zweites Beispiel, welches illustriert, inwiefern unter kulturwissenschaftlicher Perspektive historiographische Texte des Fernen Ostens als Vergleichsdokumente herangezogen werden können, schließt den Beitrag ab.

description: This poster summarizes which nuclear particles emit, absorb, and scatter with neutrinos in central engines of core collapse supernovae. Our numerical simulations show that neutrino interactions with nucleons and nuclei have great impacts on the results of supernova simulations. Before the core-bounce, neutron-rich heavy nuclei like Zn$^{80}$ are dominant at the center of collapsing cores and their neutrino absorption greatly affect the neutrino observations and following dynamics of the core. After the core-bounce, heavy nuclei are dissolved to nucleons and light clusters between the expanding shock wave and the new-born neutron star. The neutrino interactions of nucleons, deuterons and alpha particles greatly affect the shock-wave dynamics and supernova explosion of the outer envelopes.

description: Gravitational lensing time delays are well known to depend on cosmological parameters, but they also depend on the details of the mass distribution of the lens. It is usual to model the mass distribution and use time-delay observations to infer cosmological parameters, but it is naturally also possible to take the cosmological parameters as given and use time delays as constraints on the mass distribution. This paper develops a method to isolate what exactly those constraints are, using a principal-components analysis of ensembles of free-form mass models. We find that time delays provide tighter constraints on the distribution of matter in the very high dense regions of the lensing clusters. We apply it to the cluster lens SDSS J1004+4112, whose rich lensing data includes two time delays. We find, assuming a concordance cosmology, that the time delays constrain the central region of the cluster to be rounder and less lopsided than would be allowed by lensed images alone. This detailed information about the distribution of the matter is very useful for studying the dense regions of the galaxy clusters which are very difficult to study with direct measurements. A further time-delay measurement, which is expected, will make this system even more interesting.

description: Recent experimental findings and theoretical predictions suggest that nitrogen-doped CVD-grown graphene may give rise to electronic band gaps due to impurity distributions which favour segregation on a single sublattice. Here we demonstrate theoretically that such distributions give rise to more complex behaviour in the presence of edges, where geometry determines whether electrons in the sample view the impurities as a gap-opening average potential or as scatterers. Zigzag edges give rise to the latter case, and remove the electronic bandgaps predicted in extended graphene samples. We predict that such behaviour will give rise to leakage near grain boundaries with a similar geometry or in zigzag-edged etched devices. Furthermore, we examine the formation of one-dimensional metallic channels at interfaces between different sublattice domains, which should be observable experimentally and offer intriguing waveguiding possibilities.

description: Nonparametric mixture models based on the Dirichlet process are an elegant alternative to finite models when the number of underlying components is unknown, but inference in such models can be slow. Existing attempts to parallelize inference in such models have relied on introducing approximations, which can lead to inaccuracies in the posterior estimate. In this paper, we describe auxiliary variable representations for the Dirichlet process and the hierarchical Dirichlet process that allow us to perform MCMC using the correct equilibrium distribution, in a distributed manner. We show that our approach allows scalable inference without the deterioration in estimate quality that accompanies existing methods.

description: The general perception is that kernel methods are not scalable, so neural nets become the choice for large-scale nonlinear learning problems. Have we tried hard enough for kernel methods? In this paper, we propose an approach that scales up kernel methods using a novel concept called doubly stochastic functional gradients''. Based on the fact that many kernel methods can be expressed as convex optimization problems, our approach solves the optimization problems by making two unbiased stochastic approximations to the functional gradient---one using random training points and another using random features associated with the kernel---and performing descent steps with this noisy functional gradient. Our algorithm is simple, need no commit to a preset number of random features, and allows the flexibility of the function class to grow as we see more incoming data in the streaming setting. We demonstrate that a function learned by this procedure after t iterations converges to the optimal function in the reproducing kernel Hilbert space in rate O(1/t), and achieves a generalization bound of O(1/\sqrt{t}). Our approach can readily scale kernel methods up to the regimes which are dominated by neural nets. We show competitive performances of our approach as compared to neural nets in datasets such as 2.3 million energy materials from MolecularSpace, 8 million handwritten digits from MNIST, and 1 million photos from ImageNet using convolution features.

description: The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs), conducted with a 60/90 cm Schmidt telescope at Xinglong station of NAOC. This survey repeatedly covers ~ 1000 square degrees of the north sky with a cadence of 3-4 days. With an exposure of 60 s, the survey reaches a limited unfiltered magnitude of about 19.5 mag. This enables us to discover supernovae at their relatively young stages. In this paper, we describe the overall performance of our survey during the first year and present some preliminary results.

description: Orchestration is an emergent concept, understood as a style of interfirm coordination via indirect governance, which has gained attention due to its relevance for joint value creation and delivery across a diverse set of actors and stakeholders. The purpose of this conference paper is to present the progress of our review thus far and receive feedback for the development and understanding of this important concept. Overall, the aim of the review is to consolidate and clarify understanding on inter-organizational orchestration to direct future studies on this topic. To achieve this, we have followed appropriate guidelines for collecting relevant papers systematically and are currently at the stage of finalising our sample before conducting abductive qualitative analyses. Preliminary findings suggests that orchestration has previously been examined from an intra-organizational perspective, focussed on the resource-based view and capabilities-based view, where this review calls for a higher level of analysis at the inter-organizational perspective. We provide definitions of the concept and discuss initial emergent themes including: antecedents, roles & types, capabilities, mechanisms, and benefits & outcomes. Particularly for platform and ecosystem scholars this review provides comprehension and clarity on orchestration from an inter-organizational perspective, in order to guide future research. While practitioners, notably orchestrators (i.e. hub-firms), can learn from these studies best practices relevant for future management.
Measurement of beam related gamma background using plastic scintillator at JSNS$^{2}$

description: The purpose of the JSNS$^{2}$ experiment is to search for sterile neutrinos with Δm$^{2}$ near 1eV$^{2}$. A 3 GeV J-PARC proton beam incident on a mercury target produces an intense neutrino beam from muon decay at rest. which oscillate to anti-electron neutrinos. The JSNS$^{2}$ detector is located at 24 m baseline from the target. The detector has a fiducial volume of 17 tons filled with GdLS, that efficiently can detect electron anti-neutrinos via the IBD reaction follow by a gamma signal from the captured neutron on Gd. It is essential to shield gamma background to discern inverse beta decay signals. Lead blocks and iron plates are placed on the floor to reduce this beam related gamma background, which is measured using plastic scintillator. We present the results of a study of the gamma background after shielding and compared it with Monte Carlo simulations.
