description: The integration of digital tools in mathematics education is considered both promising and problematic. To deal with this issue, notions of webbing and instrumental orchestration are developed. However, the two seemed to be disconnected, and having different cultural and theoretical roots. In this article, we investigate the distinct and joint journeys of these two theoretical perspectives. Taking some key moments in recent history as points of de- parture, we conclude that the two perspectives share an importance attributed to digital tools, and that initial differences, such as different views on the role of digital tools and the role of the teacher, have become more nuances. The two approaches share future chal- lenges to the organization of teachers'collaborative work and their use of digital resources.

title: Kinds and classification in consciousness science
Creators: name: Whiteley, Cecily
Publisher: name: London School of Economics and Political Science (LSE)

description: Understanding the biological basis of consciousness is one of the central challenges for modern science. Is a mature scientific explanation really possible, and if so, how should consciousness science be organized so as to achieve this? This thesis is a collection of four papers which approach these questions via an account of the natural categories or ‘kinds’, drawn from philosophy of science, to which paradigmatic mental phenomena like consciousness belong. The central claims defended in the thesis are twofold. Firstly, that to facilitate a mature science of consciousness it is crucial to explicitly introduce a new organizing concept of consciousness modelled on the kinds of concepts which underpin previous successful explanations of other natural phenomena – that of a natural kind concept of consciousness . This draws on the general observation that some concepts are better suited to scientific theorizing about the world than others, and thus that progress in scientific and philosophical domains can be (and indeed, has often been) made by working to refine our existing conceptual schemes to reflect this. Secondly, that a mature science of consciousness will be one which recognizes the reality and explanatory importance of a particular category of mental phenomena called ‘global states of consciousness’ which includes dreaming and wakefulness. Examination of this latter claim leads to a third idea explored and motivated in the thesis which brings consciousness science into closer connection with psychiatry. This is the hypothesis that Major Depressive Disorder involves a change to a subject’s global state of consciousness, marking a change from a state of ordinary wakeful consciousness to an altered ‘depressive state’ of consciousness akin to a dream or psychedelic state.

description: In any realistic quantum metrology scenarios, the ultimate precision in the estimation of parameters is limited not only by the so-called Heisenberg scaling, but also the environmental noise encountered by the underlying system. In the context of quantum estimation theory, it is of great significance to carefully evaluate the impact of a specific type of noise on the corresponding quantum Fisher information (QFI) or quantum Fisher information matrix (QFIM). Here we investigate the multiple phase estimation problem for a natural parametrization of arbitrary pure states under white noise. We obtain the explicit expression of the symmetric logarithmic derivative (SLD) and hence the analytical formula of QFIM. Moreover, the attainability of the quantum Cramér-Rao bound (QCRB) is confirmed by the commutability of SLDs and the optimal estimators are elucidated for the experimental purpose. These findings generalize previously known partial results and highlight the role of white noise in quantum metrology.

Creators: name: Landeck, Maximilian

Publisher: name: GI
Year: 2023

description: In this article, we present a selection of recent studies from our research group that investigated the relationship between time perception and virtual reality (VR). We focus on the influence of avatar embodiment, visual fidelity, motion perception, and body representation. We summarize findings on the impact of these factors on time perception, discuss lessons learned, and implications for future applications. In a waiting room experiment, the passage of time in VR with an avatar was perceived significantly faster than without an avatar. The passage of time in the real waiting room was not perceived as significantly different from the waiting room in VR with or without an avatar. In an interactive scenario, the absence of a virtual avatar resulted in a significantly slower perceived passage of time compared to the partial and full-body avatar conditions. High and medium embodiment conditions are assumed to be more plausible and to less different from a real experience. A virtual tunnel that induced the illusion of self-motion (vection) appeared to contribute to the perceived passage of time and experience of time. This effect was shown to increase with tunnel speed and the number of tunnel segments. A framework was proposed for the use of virtual zeitgebers along three dimensions (speed, density, synchronicity) to systematically control the experience of time. The body itself, as well as external objects, seem to be addressed by this theory of virtual zeitgebers. Finally, the standardization of the methodology and future research considerations are discussed.
Towards EHR interoperability in Tanzania hospitals: Issues, Challenges and Opportunities

description: This study aimed at identifying the issue, challenges and opportunities from the health consumers in Tanzania towards interoperability of electronic health records. Recognizing that we conducted a study to identify the challenges, issues and opportunities towards health information exchange. The study was conducted in three major cities of Tanzania. This was in order to come up with a clear picture of how to implement some EHRs that will be trusted by health consumers. The participants (n=240) were surveyed on computer usage, EHRs knowledge, demographics, security and privacy issues. A total of 200 surveys were completed and returned (83.3% response rate). 67.5% were women, 62.6% had not heard of EHRs, 73% highly concerned about privacy and security of their information. 75% believed that introduction of various security mechanisms will make EHRs more secure. A number of chi-square tests (p<0.05) showed there was a strong relationship among the variable of age, computer use, EHRs knowledge and concerns for privacy and security. The study showed that there was a small difference of 8.5% between those who think EHRs are safer than paper records and those who think otherwise. The general observation of the study was that in order to make EHRs successful, then the issue of security, and health consumer involvement were two key towards the road of successful EHRs in our hospitals practices and that will make consumers more willing to allow their records to be shared.

description: We discuss the cosmological inflation in the context of $f(Q)$ non-metric gravity, where $Q$ is the non-metric scalar. After introducing conformal transformations for $f(Q)$ gravity, we first focus on the potential-slow-roll inflation by studying the corresponding potentials for different forms of the function $f(Q)$ in the Einstein frame. Secondly, we investigate the Hubble-slow-roll inflation for three classes of inflationary potentials considered for the specific form $f(Q)\propto Q^{2}$, in the Jordan frame. We compare results in both approaches with observations coming from Planck and BICEP2/Keck array satellites. Observational constraints on the parameters space of the models are obtained as well.

description: Rate constants for the N + C2 reaction have been measured in a continuous supersonic flow reactor over the range 57 K to 296 K by the relative rate technique employing the N + OH - H + NO reaction as a reference. Excess concentrations of atomic nitrogen were produced by the microwave discharge method and C2 and OH radicals were created by the in-situ pulsed laser photolysis of precursor molecules C2Br4 and H2O2 respectively. In parallel, quantum dynamics calculations were performed based on an accurate global potential energy surfaces for the three lowest lying quartet states of the C2N molecule. The 14A" potential energy surface is barrierless, having two deep potential wells corresponding to the NCC and CNC intermediates. Both the experimental and theoretical work show that the rate constant decreases to low temperature, although the experimentally measured values fall more rapidly than the theoretical ones except at the lowest temperatures. Astrochemical simulations indicate that this reaction could be the dominant source of CN in dense interstellar clouds.

description: Ever since Davis’ Technology acceptance model for information technology has been introduced in the 1980ies, ease of use has been identified as a key determinant of people’s willingness to use information systems. This factor is particularly relevant for information and communication technology (ICT) for disaster situations, where users are under severe stress, potentially in danger, and have to cope with adverse conditions such as partial or complete breakdowns of infrastructure, power blackouts, and network congestions. The impact of such adverse conditions show that ease of use of ICT for disaster management and crisis communication is not only determined by the characteristics of the user interface, but also substantially impacted by properties of the backend and the infrastructure, such as its resilience and availability. This paper proposes a generalized metric for a holistic assessment of public safety systems and services for disaster management as well as emergency and crisis communication. This metric can be used to compare different ICT alternatives and to extend existing qualitative and quantitative approaches such as thinking aloud, focus groups, surveys and field tests by specifically addressing the unique aspects of a disasters which are difficult to simulate in trials and difficult to assess in interviews and surveys, in particular if a newly developed system or technology has never been used in a real disaster setting so far.1

description: We present a new case of duality between integrable many-body systems, where two systems live on the action-angle phase spaces of each other in such a way that the action variables of each system serve as the particle positions of the other one. Our investigation utilizes an idea that was exploited previously to provide group-theoretic interpretation for several dualities discovered originally by Ruijsenaars. In the group-theoretic framework one applies Hamiltonian reduction to two Abelian Poisson algebras of invariants on a higher dimensional phase space and identifies their reductions as action and position variables of two integrable systems living on two different models of the single reduced phase space. Taking the cotangent bundle of U(2n) as the upstairs space, we demonstrate how this mechanism leads to a new dual pair involving the BC(n) trigonometric Sutherland system. Thereby we generalize earlier results pertaining to the A(n) trigonometric Sutherland system as well as a recent work by Pusztai on the hyperbolic BC(n) Sutherland system.

Une nouvelle démonstration d'irrationalité de racine carrée de 2 d'après les Analytiques d'Aristote
Creators: name: Ofman, Salomon
Publisher: name: arXiv

description: To account for the first proof of existence of an irrational magnitude, historians of science as well as commentators of Aristotle refer to the texts on the incommensurability of the diagonal in Prior Analytics, since they are the most ancient on the subject. The usual proofs suggested by the historians of science derive from a proposition found at the end of Book X of Euclid's Elements. But its conclusions, using the representation of fractions as a ratio of two integers relatively prime i.e. the proposition VII.22 of the Elements, do not match the Aristotelian texts. In this article, we propose a new demonstration conformed to these texts. They are based on very old results of the odd/even theory. Since they use neither the proposition VII.22, nor any other result proved by a reductio ad absurdum, it seems to be the first result which was impossible to prove in another way. The significance of this result, revealing a complete new territory in Mathematics, the field of irrational magnitudes, accounts for the centrality gained afterwards by this kind of reasoning, firstly in Mathematics, then in all forms of rational discourse. From the consequences of this new proof, we can construe very simply the lecture on the irrationals in the mathematical text in Plato's Theaetetus (147d-148b). It will be done in an article to appear in a forthcoming volume.

description: We describe the first steps in the development of an artificial agent focused on the Brazilian maritime territory, a large region within the South Atlantic also known as the Blue Amazon. The "BLue Amazon Brain" (BLAB) integrates a number of services aimed at disseminating information about this region and its importance, functioning as a tool for environmental awareness. The main service provided by BLAB is a conversational facility that deals with complex questions about the Blue Amazon, called BLAB-Chat; its central component is a controller that manages several task-oriented natural language processing modules (e.g., question answering and summarizer systems). These modules have access to an internal data lake as well as to third-party databases. A news reporter (BLAB-Reporter) and a purposely-developed wiki (BLAB-Wiki) are also part of the BLAB service architecture. In this paper, we describe our current version of BLAB's architecture (interface, backend, web services, NLP modules, and resources) and comment on the challenges we have faced so far, such as the lack of training data and the scattered state of domain information. Solving these issues presents a considerable challenge in the development of artificial intelligence for technical domains.

description: League Championship Algorithm (LCA) is a sports-inspired population based algorithmic framework for global optimization over a continuous search space first proposed by Ali Husseinzadeh Kashan in the year 2009. A common characteristic between all population based optimization algorithms similar to the LCA is that, they attemt to move a population of achievable solutions to potential areas of the search space during optimization. In this paper, we proposed a job scheduling algorithm based on the L CA optimization technique for the infrastructure as a service (IaaS) cloud. Three other established algorithms i.e. First Come First Served (FCFS), Last Job First (LJF) and Best Effort First (BEF) were used to evaluate the performance of the proposed algorithm. All four algorithms assumed to be non-preemptive. The parameters used for this experiment are the average response time and the average completion time. The results obtained shows that, LCA scheduling algorithm perform moderately better than the other algorithms as the number of virtual machines increases.

description: We examine the impact of different anisotropic relics on inflation, in particular the predictions on the density perturbations. These relics can be the source of the large scale anomalies in the cosmic microwave background. There are two different types of background relics, one from the matter sector and the other purely from the metric. Although the angular-dependence of the statistical anisotropy in both cases are degenerate, the scale-dependence are observationally distinctive. In addition, we demonstrate that non-Bunch-Davies vacuum states can extend the statistical anisotropy to much shorter scales, and leave a scale-dependence that is insensitive to the different backgrounds but sensitive to the initial quantum state.

description: The overarching societal integration of social robots requires positive experiences. However, frameworks for specifically considering the interaction experience with social robots in public spaces do ot exist. Previous research suggests that the experience concepts of User Experience (UX) and Customer Experience (CX) should be equally considered in the design process of applications of social robots. Building on this, we propose an interdisciplinary framework for evaluating and optimizing UX and CX in human-robot interaction (HRI), along the Customer Journey (CJ). The framework differentiates interdisciplinary evaluation criteria along adapted contact phases compared to the conventional CJ including the identification of associated touchpoints with a focus on UX and CX. It considers how the individual touchpoints and experiences made at each touchpoint (pain and gain points) during the respective phase can be methodically evaluated and related to each other. It is meant as a concept from which implications can be derived as to how UX and CX can be integrated into the interaction concepts in order to achieve a long-term stable intention to use and loyalty.

description: This paper contributes to tourism knowledge by critically analysing the social model of
 disability as it applies to neurodiversity. It concludes that neurodiversity is poorly
 problematised within tourism literature. Thus, while the social model has been widely adopted
 by the industry and governments, it lacks the potency required to challenge the focus of industry
 providers on serving the needs of neurotypical holidaymakers. The model fails to identify what
 changes are required and who should have responsibility for implementing them. The paper
 further applies the social model to a particular example of neurodiversity – the challenges
 involved in holidaymaking for families with autistic children– and develops a framework for
 action with three tiers of responsibility (governments, the tourism system, neurodiverse
 families). Finally, the paper identifies a research agenda for the future study of tourism and
 neurodiversity with particular reference to the responsibilities of the tourism industry, tourists
 and governments (including charitable organisations).

description: Solid-state qubits have recently advanced to the level that enables them, in-principle, to be scaled-up into fault-tolerant quantum computers. As these physical qubits continue to advance, meeting the challenge of realising a quantum machine will also require the engineering of new classical hardware and control architectures with complexity far beyond the systems used in today's few-qubit experiments. Here, we report a micro-architecture for controlling and reading out qubits during the execution of a quantum algorithm such as an error correcting code. We demonstrate the basic principles of this architecture in a configuration that distributes components of the control system across different temperature stages of a dilution refrigerator, as determined by the available cooling power. The combined setup includes a cryogenic field-programmable gate array (FPGA) controlling a switching matrix at 20 millikelvin which, in turn, manipulates a semiconductor qubit.

description: In this paper we present the results of an experiment to increase the attraction of a public display. To do so, we added a gamification component to improve the frequency of interaction and did an in-the-wild evaluation of the changes by analyzing the automatically logged data in combination with conducting a survey of the staff. We compare interaction data gathered before and during the experiment, and highlight the differences in these two data sets and explain their significance in prospect to the experiment. First, we discuss whether we achieved our goal of increasing the attraction or not based on the interaction data. Second we evaluate the results of our survey in which we asked people that work near the public display and possibly interacted with it, to gather some more information. The combination of both information sources allows us to further answer a question regarding intrinsic and extrinsic motivational factors to interact with smart screens.

Four fountains have been in operation for more than two years and are included in the ensemble used to generate the USNO master clock. Individual fountain performance is characterized by a white-frequency noise level below $2\times 10^{-13}$ and fractional-frequency stability routinely reaching the low $10^{-16}$s. The highest performing pair of fountains exhibits stability consistent with each fountain integrating as white frequency noise, with Allan deviation surpassing $6\times 10^{-17}$ at $10^7$~s, and with no relative drift between the fountains at the level of $7.5 \times 10^{-19}$/day. As an ensemble, the fountains generate a timescale with white-frequency noise level of $1\times 10^{-13}$ and long-term frequency stability consistent with zero drift relative to the world's primary standards at $1 \times 10^{-18}$/day. The rubidium fountains are reported to the BIPM as continuously running clocks, as opposed to secondary standards, the only cold-atom clocks so reported. Here we further characterize the performance of the individual fountains and the ensemble during the first two years in an operational environment, presenting the first look at long-term continuous behavior of fountain clocks.

description: The B fields in OB stars (BOB) survey is an ESO large programme collecting spectropolarimetric observations for a large number of early-type stars in order to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive stars. As of July 2014, a total of 98 objects were observed over 20 nights with FORS2 and HARPSpol. Our preliminary results indicate that the fraction of magnetic OB stars with an organised, detectable field is low. This conclusion, now independently reached by two different surveys, has profound implications for any theoretical model attempting to explain the field formation in these objects. We discuss in this contribution some important issues addressed by our observations (e.g., the lower bound of the field strength) and the discovery of some remarkable objects.

description: Liquid mass transfer has emerged as a promising approach to induce weight perception in Virtual Reality (VR). This concept utilizes a tubing system to exchange a liquid between two or more units, to change their weight. As at least one of these units is attached to the user’s body or controller, different weight sensations can be achieved. In this position paper, we provide an overview of related work in the area of liquid-based weight-changing devices, point at limitations of their approach and discuss future directions for their advancement.

description: Bicyclists belong to vulnerable road users (VRUs) and are increasingly involved in accidents. As accidents pose a significant risk to their safety due to the lack of protection from the bike or clothing, there is a need for effective measures to enhance bicyclists’ safety. While road infrastructure improvements can play a role, they are often challenging to implement and costly. In this paper, we propose the use of smart wearables as a solution for providing hazard notifications to cyclists. Specifically, we focus on the application of different systems, including augmented reality (HoloLens) and virtual reality (VR headset, CAVE), and present preliminary results from evaluations conducted on real roads, including closed test tracks. In this workshop, we will present our findings and progress to date in using these technologies to improve cyclist safety. We believe that by usign smart wearables, cyclists are better able to recognize and manage hazardous situations, leading to a reduction in accidents and improved safety outcomes.
