science forum South Africa

description: During South Africa’s fourth Science Forum, the anticipated vision and strategy of the African Open Science Platform (AOSP) was announced. This pan-African endeavour aims to position African scientists at the cutting edge of data intensive science by stimulating interactivity and creating opportunity through the development of efficiencies of scale, the creation of critical mass through shared capacities, and amplifying impact through a commonality of purpose and voice.

The AOSP was presented by Dr Khotso Mokhele, co-chairperson of the advisory council of the AOSP [and former President of the National Research Foundation (NRF)], and was acknowledged by the Minister of Science and Technology (DST), Minister Kubayi-Ngubane.

The conceptualisation of the AOSP was initiated during the 2015 Science Forum, where the first meeting of Science International (ICSU, ISSC, TWAS, IAP) was hosted, leading to the publication of an international accord on open data in a big data world. This ignited a conversation that resulted in the launch of the AOSP pilot project during the 2016 Science Forum.

During the next two years, the founding members of the AOSP will operationalise the platform, to be initiated during a meeting of the founding members and international funders in May 2019, hosted by Dr Ismail Serageldin who also serves as the AOSP co-chair.

It is anticipated that the fully-fledged platform will be operationalised in 2020. The DST, NRF, the International Council of Science, CODATA, and the SA Academy of Science, actively participate in the initiative.

description: We present a new computer program, feyntrop, which uses the tropical geometric approach to evaluate Feynman integrals numerically. In order to apply this approach in the physical regime, we introduce a new parametric representation of Feynman integrals that implements the causal $i\varepsilon$ prescription concretely while retaining projective invariance. feyntrop can efficiently evaluate dimensionally regulated, quasi-finite Feynman integrals, with not too exceptional kinematics in the physical regime, with a relatively large number of propagators and with arbitrarily many kinematic scales. We give a systematic classification of all relevant kinematic regimes, review the necessary mathematical details of the tropical Monte Carlo approach, give fast algorithms to evaluate (deformed) Feynman integrands, describe the usage of feyntrop and discuss many explicit examples of evaluated Feynman integrals.

description: In fall line cultivation of vineyards, the vines are planted vertically to the hill's slope. Therefore, steep slope vineyards require a high amount of manual labor, doubling production costs. Working in such environments is exhausting and laborious. Therefore, autonomous robots should assist humans in reducing costs and increasing safety. However, current state-of-the-art robotic systems and control architectures are not designed to work in such harsh environments with extreme terrains. Therefore, this work proposes and modular control architecture for safe and robust autonomous working in steep slope environments. Tests in an authentic vineyard near the Moselle river in Germany prove the approach's feasibility and robustness.
The effect of a finite time horizon in the durable good monopoly problem with atomic consumers

description: A durable good is a long-lasting good that can be consumed repeatedly over time, and a duropolist is a monopolist in the market of a durable good. In 1972, Ronald Coase conjectured that a duropolist who lacks commitment power cannot sell the good above the competitive price if the time between periods approaches zero. Coase's counterintuitive conjecture was later proven by Gul et al. (1986) under an infinite time horizon model with non-atomic consumers. Remarkably, the situation changes dramatically for atomic consumers and an infinite time horizon. Bagnoli et al. (1989) showed the existence of a subgame-perfect Nash equilibrium where the duropolist extracts all the consumer surplus. Observe that, in these cases, duropoly profits are either arbitrarily smaller or arbitrarily larger than the corresponding static monopoly profits -- the profit a monopolist for an equivalent consumable good could generate. In this paper we show that the result of Bagnoli et al. (1989) is in fact driven by the infinite time horizon. Indeed, we prove that for finite time horizons and atomic agents, in any equilibrium satisfying the standard skimming property, duropoly profits are at most an additive factor more than static monopoly profits. In particular, duropoly profits are always at least static monopoly profits but never exceed twice the static monopoly profits. Finally we show that, for atomic consumers, equilibria may exist that do not satisfy the skimming property. For two time periods, we prove that amongst all equilibria that maximize duropoly profits, at least one of them satisfies the skimming property. We conjecture that this is true for any number of time period.

Lo es también que la tecnología desarrollada por Amazon pueda reportar suntuosas ganancias al venderla a otras empresas que deseen aplicar en sus tiendas tan innovadora aplicación, y que pasarán a ser meros subsidiarios de este nuevo señor feudal corporativo. Amazon, en línea con otros gigantes tecnológicos, continúa esforzándose en robotizar la mayoría de sus operaciones y, por ende, las nuestras son cada vez más ‘democracias robotizadas’. La finalidad no es otra que eliminar mano de obra en todo lo que sea posible. Además, ahora sabemos que también quiere vender la tecnología y hacerse con un mercado de rentabilidad incalculable.

description: Die Digitalisierung schreitet auch in der Landwirtschaft immer weiter voran. Vermehrt werden in landwirtschaftlichen Betrieben sogenannte Smart Farming-Technologien eingesetzt, mit deren Hilfe verschiedenste Arbeitsabläufe automatisiert ablaufen, kontrolliert werden und mit anderen Betrieben ausgetauscht werden können. Durch die verfügbaren Daten und die Vernetzung mit anderen Betrieben, ergeben sich vielfältige neue Möglichkeiten in Bezug auf ressourcenschonendes, wirtschaftlicheres und kollaboratives Arbeiten. Problematiken ergeben sich mit Blick auf die Speicherung dieser sensiblen Betriebsdaten, vor allem, wenn hierfür nur einige wenige Anbieter zur Verfügung stehen. Das Forschungsprojekt „AgriRegio“ soll die digitalisierte Datenerfassung und -nutzung in landwirtschaftlichen Betrieben widerstandsfähiger machen und die sicherheitskritische Infrastruktur schützen. Sieben Projektpartner erproben dazu smarte Sensoren auf Basis standardisierter Open-Source-Technologien in der Landwirtschaft, bei denen die Betriebsdaten dezentral auf lokalen Servern gespeichert werden.

description: We study the connection between the affine degenerate Grassmannians in type $A$, quiver Grassmannians for one vertex loop quivers and affine Schubert varieties. We give an explicit description of the degenerate affine Grassmannian of type $GL_n$ and identify it with semi-infinite orbit closure of type $A_{2n-1}$. We show that principal quiver Grassmannians for the one vertex loop quiver provide finite-dimensional approximations of the degenerate affine Grassmannian. Finally, we give an explicit description of the degenerate affine Grassmannian of type $A_1^{(1)}$, propose a conjectural description in the symplectic case and discuss the generalization to the case of the affine degenerate flag varieties.

description: Digitalisierung und Datafizierung in Gesellschaft, Politik, Wissenschaft und Wirtschaft haben unmittelbaren Einfluss auf die zukünftige Hochschullehre und darauf, welche Kompetenzen Studierende benötigen. Eine wesentliche Schlüsselkompetenz in diesem Diskurs bildet die Data Literacy. Dabei besteht Konsens, dass Lehr-Lern-Prozesse im Sinne einer Data Literacy Education (DLE) inter- bzw. transdisziplinär gestaltet werden müssen. Ungeklärt ist hierbei jedoch noch der Beitrag der Informatik zur DLE in der Hochschullehre. In einer Interviewstudie wird diese Problematik genauer untersucht, indem Hochschullehrende diverser Disziplinen u.a. zu ihrem Verständnis von DLE, dem Beitrag der Fachdisziplinen hierzu und den Anknüpfungspunkten zur Informatik befragt werden. Die bisherigen Ergebnisse zeigen Einigkeit der unterschiedlichen Disziplinen auf, dass die Stärkung der Data Literacy von Studierenden fächerübergreifend ein notwendiges und dringendes Anliegen ist. Weiterhin zeigt die Studie die Herausforderungen und die interdisziplinäre Diskrepanz im Aushandlungsprozess einer angemessenen Berücksichtigung von informatischen Inhalten in der hochschulweiten fachspezifischen DLE. Sie liefert aber auch Anknüpfungspunkte zur Überwindung dieser Diskrepanz.

description: Complementarity is one of the main features of quantum physics that radically departs from classical notions. Here we consider the limitations that this principle imposes due to the unpredictability of measurement outcomes of incompatible observables. For two-level systems, it is shown that any preparation violating complementarity enables the preparation of a non-signalling box violating Tsirelson's bound. Moreover, these "beyond-quantum" objects could be used to distinguish a plethora of non-orthogonal quantum states and hence enable improved cloning protocols. For higher-dimensional systems the main ideas are sketched.

Techno-economic and carbon footprint assessment of advanced waste-to-energy with carbon capture and storage for East Coast Cluster
Creators: name: Hanak, Dawid
Publisher: name: OSF
Year: 2024

description: The East Coast Cluster, identified as one of the Track-1 clusters, aims to deliver CCUS infrastructure capable of removing nearly 50% of the UK’s industrial emissions. To achieve this ambitious target, the cluster’s decarbonisation will need negative emission power and fuels that can be delivered, for example, via carbon capture and storage (CCS) retrofits to waste-to-energy (WtE) plants. It is crucial to note that on the national scale, WtE sector is projected to contribute up to 20 MtCO2e per annum in the UK by mid-2020, surpassing the emissions from industrial processes. Therefore, the need to develop low-carbon alternatives for WtE is imperative.

Gerade an Mittelschulen ist es jedoch oft nicht einfach, Schülerinnen und Schüler für diese Themen zu begeistern. Dazu kommt, dass an dieser Schulart häufig fachfremde LehrerInnen mit wenig Vorwissen Informatik unterrichten sollen. In diesem Beitrag wird der EmiLe Computer Club (ECC) vorgestellt, der den Fokus auf den Teilbereich des Programmierens legt. Im ECC wird an einer Montessori-Schule im Münchner Südosten seit dem Schuljahr 2020/21 Programmieren von der 3.8. Klasse spielerisch und ungezwungen vermittelt. Es wird das Konzept des ECC vorgestellt und ausgewählte Beispiele aus der Praxis werden präsentiert. Darüber hinaus soll der Beitrag die Diskussion zur Verbindung der Montessori-Pädagogik mit der Ausbildung junger Menschen im Programmieren anregen.

description: Remarkable progress of quantum information theory (QIT) allowed to formulate mathematical theorems for conditions that data-transmitting or data-processing occurs with a non-negative entropy gain. However, relation of these results formulated in terms of entropy gain in quantum channels to temporal evolution of real physical systems is not thoroughly understood. Here we build on the mathematical formalism provided by QIT to formulate the quantum H-theorem in terms of physical observables. We discuss the manifestation of the second law of thermodynamics in quantum physics and uncover special situations where the second law can be violated. We further demonstrate that the typical evolution of energy-isolated quantum systems occurs with non-diminishing entropy.

description: During transport of boar semen for artificial insemination of pigs, there is currently no mobile measuring system available for recording all relevant impact factors systematically. Based on a survey of artificial insemination centers, this paper describes the requirements for a systematic approach to record all relevant environmental impact factors during the transport of artificial insemination doses. The developed system architecture as well as the implementation to fulfil the derived requirements is presented. An Arduino Nano 33 BLE Sense with an external temperature sensor and an external luminance sensor is used as the measuring device. This device sends measurement data to a smartphone app using Bluetooth Low Energy (BLE). The app persists the measurement data on a local storage on the smartphone. With the presented mobile measuring system, a comprehensive monitoring for transport of artificial insemination doses becomes available.

description: The Square Kilometre Array (SKA) will produce spectroscopic surveys of tens to hundreds of millions of HI galaxies, eventually covering 30,000 sq. deg. and reaching out to redshift z~2. The huge volumes probed by the SKA will allow for some of the best constraints on primordial non-Gaussianity, based on measurements of the large-scale power spectrum. We investigate various observational set-ups for HI galaxy redshift surveys, compatible with the SKA Phase 1 and Phase 2 (full SKA) configurations. We use the corresponding number counts and bias for each survey from realistic simulations and derive the magnification bias and the evolution of source counts directly from these. For the first time, we produce forecasts that fully include the general relativistic effects on the galaxy number counts. These corrections to the standard analysis become important on very large scales, where the signal of primordial non-Gaussianity grows strongest. Our results show that, for the full survey, the non-Gaussianity parameter fNL can be constrained down to an accuracy of 1.54. This improves the current limit set by the Planck satellite by a factor of five, using a completely different approach.

description: In this paper we discuss different recursion relations (BCFW and all-line shift) for the form factors of the operators from the $\mathcal{N}=4$ SYM stress-tensor current supermultiplet $T^{AB}$ in momentum twistor space. We show that cancelations of spurious poles and equivalence between different types of recursion relations can be naturally understood using geometrical interpretation of the form factors as special limit of the volumes of polytopes in $\mathbb{C}\mathbb{P}^4$ in close analogy with the amplitude case. We also show how different relations for the IR pole coefficients can be easily derived using momentum twistor representation. This opens an intriguing question - which of powerful on-shell methods and ideas can survive off-shell ?

description: Universities have rarely been challenged to radically evolve and transform as they have been in the Covid-19 pandemic. The conduct of teaching and research, as well as the environment of staff and administration, have had to digitalize and transform under time pressure. This development has placed and continues to place high demands on IT and its infrastructure. In addition, new challenges have emerged, such as technology-based future skills, cybersecurity, and the need for an agile university-wide IT governance. Mastering these requires IT to address the present and the future already today. Therefore, in this article, we conducted a literature analysis to identify and examine current and future challenges for IT and its infrastructure in universities. We identified twelve overarching challenges, which we describe individually. This paper provides starting points for further IT-related research and essential viewing angles for IT governance in universities for practitioners.

description: La campaña del PSOE para el 28-A canalizó, en buena medida, mensajes que reclamaban revertir los retrocesos de las políticas sociales. Recuérdese que los programas de bienestar social superan el 50% del gasto público total. Educación, sanidad, pensiones y protección al desempleo y, en general las transferencias de rentas entre ricos y pobres o mayores y jóvenes, ocupan las principales preocupaciones de los españoles en su vida social. Los partidos de derecha prefirieron enfatizar aspectos fulgurantes como el liderazgo (mejor, la carencia del mismo) o la lealtad emotiva a una España uniforme, alfa y omega de la regimentación política ciudadana. Los mensajes de las formaciones de izquierda (PSOE y Unidas Podemos) recabaron explícitamente el apoyo de aquellos grupos sociales que más perdieron con la crisis desatada en 2007-08. En el conjunto de las propuestas electorales, la campaña giró en torno a asuntos de política doméstica, muchos de ellos relativos al asunto del encaje territorial de la pluralidad interna de España.

description: Let $\cal{N}=\{1,\cdots,n\}$. The entropy function $\bf h$ of a set of $n$ discrete random variables $\{X_i:i\in\cal N\}$ is a $2^n$-dimensional vector whose entries are ${\bf{h}}({\cal{A}})\triangleq H(X_{\cal{A}}),\cal{A}\subset{\cal N} $, the (joint) entropies of the subsets of the set of $n$ random variables with $H(X_\emptyset)=0$ by convention. The set of all entropy functions for $n$ discrete random variables, denoted by $Γ^*_n$, is called the entropy function region for $n$. Characterization of $Γ^*_n$ and its closure $\overline{Γ^*_n}$ are well-known open problems in information theory. They are important not only because they play key roles in information theory problems but also they are related to other subjects in mathematics and physics. In this paper, we consider \emph{partition-symmetrical entropy functions}. Let $p=\{\cal{N}_1,\cdots, \cal{N}_t\}$ be a $t$-partition of $\cal N$. An entropy function $\bf h$ is called $p$-symmetrical if for all ${\cal A},{\cal B} \subset {\cal N}$, $\bf{h}({\cal A}) = \bf{h}({\cal B})$ whenever $|{\cal A} \cap {\cal N}_i| = |{\cal B} \cap {\cal N}_i|$, $i = 1, \cdots,t$. The set of all the $p$-symmetrical entropy functions, denoted by $Ψ^*_p$, is called $p$-symmetrical entropy function region. We prove that $\overline{Ψ^*_p}$, the closure of $Ψ^*_p$, is completely characterized by Shannon-type information inequalities if and only if $p$ is the $1$-partition or a $2$-partition with one of its blocks being a singleton. The characterization of the partition-symmetrical entropy functions can be useful for solving some information theory and related problems where symmetry exists in the structure of the problems. Keywords: entropy, entropy function, information inequality, polymatroid.

description: Artificial intelligence is an essential key competence for cost reduction in companies. For this reason, the German government is promoting its use and hopes that it will lead to a digital transformation of companies. We investigated whether small and medium-sized enterprises (SMEs) also participate in this transformation by examining AI-related vacancies for their fields of activity. In particular, we observe whether the required skills of potential applicants suggest that enterprises also require artificial intelligence at an advanced stage and that quality factors such as fairness and ethics play a role. We found that the need for more advanced AI-related jobs has started increasing but still plays a minor role compared to traditional data science roles. Notably, only large companies require some of these additional skills. Moreover, many vacancies even state that a deep AI understanding is not necessarily a prerequisite.

description: E-Mails enthalten in der Regel personenbezogene Daten, die den datenschutzrechtlichen Löschvorgaben unterliegen. Eine angemessene Umsetzung der Löschvorgaben stellt jedoch die verantwortlichen Unternehmen vor eine große Herausforderung, zumal nach Erfüllung des Verarbeitungszwecks oftmals unterschiedliche (spezial-)rechtliche Aufbewahrungspflichten einer sofortigen Löschung entgegenstehen. Für die Einhaltung von Lösch- und Aufbewahrungspflichten ist es zunächst erforderlich, E-Mails, die diesen Verpflichtungen unterliegen (z.B. Rechnungen) zu identifizieren. Dieser Beitrag untersucht, inwieweit E-Mails mithilfe von maschinellem Lernen (ML) klassifiziert werden können. Für auf diese Weise klassifizierte E-Mails kann im nächsten Schritt entschieden werden, ob sie gemäß den Anforderungen der Datenschutz-Grundverordnung (DSGVO) gelöscht oder gemäß gesetzlicher Aufbewahrungsfristen länger aufbewahrt und archiviert werden müssen. Der Beitrag beschreibt zudem die Entwicklung eines Proof-of-Concept in Form eines Add-ons für Microsoft Outlook, das Nutzern erlaubt, die in ihren Postfächern enthaltenen E-Mails zu klassifizieren.

description: Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. It executes arbitrary dataflow programs in a data-parallel and pipelined manner in event-driven applications such as, fraud detection (i.e. detection of suspicious transactions), anomaly detection (i.e. detection of rare or suspicions events), rule-based alerting (i.e. identification of data which satisfy one or more rules) and many more. Despite its versatility, Apache Flink cannot automatically and optimally adjust the utilization of its underlying computing resources when streaming sources produce data at varying speeds. In order to address this issue, we describe an autonomous agent to support dynamic autoscaling for Apache Flink on Kubernetes. This agent monitors, models and adjusts Flink's behaviour by optimally modifying its allocated resources in order to match the incoming workload while achieving minimum cost. The decision making process is based on operator idleness and changes to the input's record lag. We prove that our model not only successfully maintains the performance of the application while minimizing infrastructure costs, but can provide a better performance-to-cost ratio compared to already existing work on Flink autoscaling. The effectiveness of our model is supported by an exhaustive set of synthetic and real life workloads aimed to simulate a plethora of possible scenarios.

description: Autonomous weapon systems (AWS) are not yet established, but strong military motives exist to develop and introduce them. A major fear is that they could deteriorate the stability in a crisis between two actors. To investigate this problem, we use agent-based modeling and simulation (ABMS). Here one AWS fleet patrols the perimeter of a protected area while a second moves outside. AWS of the first shoot if they sense being attacked or if AWS of the second enter the protected area. Errors in attack detection or in position determination can lead to escalation from crisis into war. The escalation probability is evaluated with a variation of these errors. Moreover, we elaborate on the shortcomings of ABMS in general.

description: Due to climate change and the effect on human health, there is an urgency to observe and understand the environment. To achieve this goal, knowledge about the development of environmental parameters over time and space is necessary. The analysis of the underlying data can therefore be done with spatial, temporal or even spatio-temporal methods. These methods can also be combined: First spatial,then temporal analyses and vice versa. In this work, we compare the effect of the decision whether to first analyze the data spatially, temporally or both simultaneously. We chose temperature data in Baden-Württemberg, yearly and monthly aggregated, for our comparison.

description: Numerical simulations of extereme mass ratio inspirals, the mostimportant sources for the LISA detector, face several computational challenges. We present a new approach to evolving partial differential equations occurring in black hole perturbation theory and calculations of the self-force acting on point particles orbiting supermassive black holes. Such equations are distributionally sourced, and standard numerical methods, such as finite-difference or spectral methods, face difficulties associated with approximating discontinuous functions. However, in the self-force problem we typically have access to full a-priori information about the local structure of the discontinuity at the particle. Using this information, we show that high-order accuracy can be recovered by adding to the Lagrange interpolation formula a linear combination of certain jump amplitudes. We construct discontinuous spatial and temporal discretizations by operating on the corrected Lagrange formula. In a method-of-lines framework, this provides a simple and efficient method of solving time-dependent partial differential equations, without loss of accuracy near moving singularities or discontinuities. This method is well-suited for the problem of time-domain reconstruction of the metric perturbation via the Teukolsky or Regge-Wheeler-Zerilli formalisms. Parallel implementations on modern CPU and GPU architectures are discussed.

description: We ask whether or not thermal light can be represented as a mixture of single broadband coherent pulses. We find that it cannot. Such a mixture is simply not rich enough to mimic thermal light; indeed, it cannot even reproduce the first-order correlation function. We show that it is possible to construct a modified mixture of single coherent pulses that does yield the correct first-order correlation function at equal space points. However, as we then demonstrate, such a mixture cannot reproduce the second-order correlation function.

description: Barrierefreiheit und Inklusion stellen bei Webanwendungen häufig hohe Hürden dar. In der Technikentwicklung dient das Universal Design als Framework für ein Produkt für alle Nutzenden. In der Realität werden jedoch häufig einzelne Lösungen entwickelt. Anhand der Entwicklung einer Indoor-Navigations App werden drei Spannungsfelder in der Technikentwicklung aufgezeigt: Bekanntheit vs. Barrierefreiheit, Detailgrad vs. Überforderung und Individualisierung vs. Datensicherheit. Dabei zeigt sich, an welchen Stellen es Herausforderungen für eine gute User Experience zwischen individuellen Bedürfnissen und einer universellen Nutzbarkeit gibt.

description: Two-sample $U$-statistics are widely used in a broad range of applications, including those in the fields of biostatistics and econometrics. In this paper, we establish sharp Cramér-type moderate deviation theorems for Studentized two-sample $U$-statistics in a general framework, including the two-sample $t$-statistic and Studentized Mann-Whitney test statistic as prototypical examples. In particular, a refined moderate deviation theorem with second-order accuracy is established for the two-sample $t$-statistic. These results extend the applicability of the existing statistical methodologies from the one-sample $t$-statistic to more general nonlinear statistics. Applications to two-sample large-scale multiple testing problems with false discovery rate control and the regularized bootstrap method are also discussed.

description: Die Nachfrage nach der breiten Verfügbarkeit von medizinischen Daten zu Forschungszwecken nimmt stetig zu. Die enormen Datenmengen bieten vor allem für Big Data Verfahren ein großes Potential. In der Gesetzgebung soll dieser Bedarf durch ein Forschungsdatenzentrum, das im Digitale-Versorgung-Gesetz (DVG) geregelt wird, erfüllt werden. Hierbei stellen sich allerdings eine Reihe von Fragen bezüglich des Datenschutzes. So sollen die Daten zwar in pseudonymisierter oder anonymisierter Form vorliegen, allerdings kann nach wie vor ein Re-Identifizierungsrisiko bestehen. Diese Ausarbeitung analysierte die bestehende Gesetzeslage und zieht überblickartig Vergleiche zu internationalen Vorschriften bezüglich der Regulierung anonymer Daten. Auf Basis dieser Analyse wird eine Erweiterung des Forschungsdatenzentrums skizziert, das mithilfe von Privatsphäre-wahrenden Technologien eine datenschutzkonforme Weitergabe von Versichertendaten ermöglichen kann.

Signature of a topological phase transition in long SN junctions in the spin-polarized density of states

description: We investigate the spin texture of Andreev bound states and Majorana states in long SN junctions. We show that measuring the spin-polarized density of states (SPDOS) allows one to identify the topological transition. In particular, we find that its total component parallel to the wire is non-zero in the topological phase for the lowest-energy state, while vanishing in the trivial one. Also, the component parallel to the Zeeman field is symmetric between positive and negative energies in the topological phase and asymmetric in the trivial phase. Moreover the SPDOS exhibits a moderate accumulation close to the SN boundary which changes sign when crossing the topological transition. We propose that these signatures may allow one to unambiguously test the formation of a topological phase via spin-resolved transport and STM measurements.
