description: Urban mobility is evolving towards sustainable transportation as awareness of the environmental impact of transportation increases. In addition, efforts to improve public health, are leading to a greater focus on micromobile means of urban transport, such as bicycles or scooters. Although the number of people using micromobile urban transport is increasing, technologies to improve rider safety have been researched mainly in the context of motorized vehicles. In this workshop, we will present research and discuss ideas for smart urban micromobility. Therefore, we invite scientists and practitioners from different backgrounds to contribute with their latest work. Our goal is to bring together micromobility and technology enthusiasts to discuss and identify opportunities to provide a smart and safer mode of transportation.

description: We study the structure of maps that Lorentz boosts induce on the spin degree of freedom of a system consisting of two massive spin-$1/2$ particles. We consider the case where the spin state is described by the Werner state and the momenta are discrete. Transformations on the spins are systematically investigated in various boost scenarios by calculating the orbit and concurrence of the bipartite spin state with different kinds of product and entangled momenta. We confirm the general conclusion that Lorentz boosts cause non-trivial behavior of bipartite spin entanglement. Visualization of the evolution of the spin state is shown to be valuable in explaining the pattern of concurrence. The idealized model provides a basis of explanation in terms of which phenomena in systems involving continuous momenta can be understood.

description: Berichte über Schlachten wurden bislang fast immer mit der Absicht betrachtet, aus ihnen das tatsächliche Geschehen zu rekonstruieren. In diesem Aufsatz geht es hingegen um die Frage, wie mittelalterliche Menschen selbst das Kampfgeschehen deuteten und beschrieben, und vor allem darum zu ermitteln, welche Rolle dabei den topographischen Eigenarten des Schlachtfeldes zukam. Es zeigt sich, dass die Verfasser der Quellen keineswegs den Ablauf des Kampfes nüchtern protokollieren wollten, sondern stets ihre spezifische Erzählabsicht verfolgten. Insbesondere versuchten sie, jene Partei, der sie selbst anhingen, möglichst günstig darzustellen. Dieser Erzählabsicht ordneten sie die Erwähnung topographischer Details klar unter. Außerdem flossen in die Schilderung auch scheinbar banaler topographischer Einzelheiten häufig Motive und Erzählmuster ein, die den Autoren und den zeitgenössischen Lesern schon bekannt waren und die daher Wahrnehmung, Erinnerung und Darstellung prägten. Aus dieser Analyse folgt, dass Rückschlüsse auf die örtlichen Gegebenheiten und den tatsächlichen Ablauf des Kampfes den Worten der Chronisten allenfalls mit größter Vorsicht zu entnehmen sind. Zugleich erweist sich, dass die sprachlichen Visualisierungsstrategien aufschlussreiche Erkenntnisse darüber bieten, wie die Autoren kriegerische Handlungen wahrnahmen.

description: Scientific knowledge develops through cumulative discoveries that build on, contradict, contextualize, or correct prior findings. Scientists and journalists often communicate these incremental findings to lay people through visualizations and text (e.g., the positive and negative effects of caffeine intake). Consequently, readers need to integrate diverse and contrasting evidence from multiple sources to form opinions or make decisions. However, the underlying mechanism for synthesizing information from multiple visualizations remains underexplored. To address this knowledge gap, we conducted a series of four experiments (N = 1166) in which participants synthesized empirical evidence from a pair of line charts presented sequentially. In Experiment 1, we administered a baseline condition with charts depicting no specific context where participants held no strong belief. To test for the generalizability, we introduced real-world scenarios to our visualizations in Experiment 2, and added accompanying text descriptions similar to on-line news articles or blog posts in Experiment 3. In all three experiments, we varied the relative direction and magnitude of line slopes within the chart pairs. We found that participants tended to weigh the positive slope more when the two charts depicted relationships in the opposite direction (e.g., one positive slope and one negative slope). Participants tended to weigh the less steep slope when the two charts depicted relationships in the same direction (e.g., both positive). Through these experiments, we characterize participants' synthesis behaviors depending on the relationship between the information they viewed, contribute to theories describing underlying cognitive mechanisms in information synthesis, and describe design implications for data storytelling.

description: In this paper we present an update on the open source MPI-AMRVAC simulation toolkit where we focus on solar- and non-relativistic astrophysical magneto-fluid dynamics. We highlight recent developments in terms of physics modules such as hydrodynamics with dust coupling and the conservative implementation of Hall magnetohydrodynamics. A simple conservative high-order finite difference scheme that works in combination with all available physics modules is introduced and demonstrated at the example of monotonicity preserving fifth order reconstruction. Strong stability preserving high order Runge-Kutta time steppers are used to obtain stable evolutions in multidimensional applications realizing up to fourth order accuracy in space and time. With the new distinction between active and passive grid cells, MPI-AMRVAC is ideally suited to simulate evolutions where parts of the solution are controlled analytically, or have a tendency to progress into or out of a stationary state. Typical test problems and representative applications are discussed, with an outlook to follow-up research. Finally, we discuss the parallel scaling of the code and demonstrate excellent weak scaling up to 30 000 processors allowing to exploit modern petascale infrastructure.

description: Although gamification in education is a pretty well-researched field, there is still considerable room for further studies and exploring the possibilities of better learning. In this study, author took two groups of marketing students and introduced gamification mechanisms to one of them addressing the need of autonomy. The idea was to introduce narration and badges but most important – the possibility of choice. Students were choosing the way the plot was going to develop while learning particular marketing topics. The survey was conducted at the beginning and at the end of semester with students’ own evaluation of their knowledge and skills concerning selected marketing topics. Repeated-measures ANOVA analysis and mean differences were conducted, however there was no significant difference spotted between the experimental and the control group. Even though results could have been more optimistic, it is a good foundation for further studies regarding gamification usage in university classes, especially as a tool addressing need for autonomy.

description: We review three different approaches for the calculation of electromagnetic multipoles, namely the Cartesian primitive multipoles, the Cartesian irreducible multipoles and the spherical multipoles. We identify the latter as the best suited to describe the scattering of electromagnetic radiation, as exemplified for an amorphous silicon sphere. These multipoles are then used to calculate the optical force acting on semiconductor, dielectric or metallic particles in a wide wavelength range, from the dipolar down to the Mie regimes.

description: Most sounds of interest consist of complex, time-dependent admixtures of tones of diverse frequencies and variable amplitudes. To detect and process these signals, the ear employs a highly nonlinear, adaptive, real-time spectral analyzer: the cochlea. Sound excites vibration of the eardrum and the three miniscule bones of the middle ear, the last of which acts as a piston to initiate oscillatory pressure changes within the liquid-filled chambers of the cochlea. The basilar membrane, an elastic band spiraling along the cochlea between two of these chambers, responds to these pressures by conducting a largely independent traveling wave for each frequency component of the input. Because the basilar membrane is graded in mass and stiffness along its length, however, each traveling wave grows in magnitude and decreases in wavelength until it peaks at a specific, frequency-dependent position: low frequencies propagate to the cochlear apex, whereas high frequencies culminate at the base. The oscillations of the basilar membrane deflect hair bundles, the mechanically sensitive organelles of the ear's sensory receptors, the hair cells. As mechanically sensitive ion channels open and close, each hair cell responds with an electrical signal that is chemically transmitted to an afferent nerve fiber and thence into the brain. In addition to transducing mechanical inputs, hair cells amplify them [...]

description: AI is being increasingly used to aid response efforts to humanitarian emergencies at multiple levels of decision-making. Such AI systems are generally understood to be stand-alone tools for decision support, with ethical assessments, guidelines and frameworks applied to them through this lens. However, as the prevalence of AI increases in this domain, such systems will begin to encounter each other through information flow networks created by interacting decision-making entities, leading to multi-AI complex systems which are often ill understood. In this paper we describe how these multi-AI systems can arise, even in relatively simple real-world humanitarian response scenarios, and lead to potentially emergent and erratic erroneous behavior. We discuss how we can better work towards more trustworthy multi-AI systems by exploring some of the associated challenges and opportunities, and how we can design better mechanisms to understand and assess such systems. This paper is designed to be a first exposition on this topic in the field of humanitarian response, raising awareness, exploring the possible landscape of this domain, and providing a starting point for future work within the wider community.

description: We consider the noncommutative space $\mathbb{R}^3_λ$, a deformation of the algebra of functions on $\mathbb{R}^3$ which yields a foliation of $\mathbb{R}^3$ into fuzzy spheres. We first review the construction of a natural matrix basis adapted to $\mathbb{R}^3_λ$. We thus consider the problem of defining a new Laplacian operator for the deformed algebra. We propose an operator which is not of Jacobi type. The implication for field theory of the new Laplacian is briefly discussed.

Distribution of quantum Fisher information in asymmetric cloning machines

description: An unknown quantum state cannot be copied on demand and broadcast freely due to the famous no-cloning theorem. Approximate cloning schemes have been proposed to achieve the optimal cloning characterized by the maximal fidelity between the original and its copies. Here, from the perspective of quantum Fisher information (QFI), we investigate the distribution of QFI in asymmetric cloning machines which produce two nonidentical copies. As one might expect, improving the QFI of one copy results in decreasing the QFI of the other copy, roughly the same as that of fidelity. It is perhaps also unsurprising that asymmetric phase-covariant cloning machine outperforms universal cloning machine in distributing QFI since a priori information of the input state has been utilized. However, interesting results appear when we compare the distributabilities of fidelity (which quantifies the full information of quantum states), and QFI (which only captures the information of relevant parameters) in asymmetric cloning machines. In contrast to the results of fidelity, where the distributability of symmetric cloning is always optimal for any d-dimensional cloning, we find that asymmetric cloning performs always better than symmetric cloning on the distribution of QFI for $d\leq18$, but this conclusion becomes invalid when $d>18$.

Polaron energies obtained by our method are in excellent agreement with recent diagrammatic Monte Carlo calculations for a wide range of interaction strengths. We calculate the effective mass of polarons and find a smooth crossover from weak to strong coupling regimes. Possible experimental tests of our results in current experiments with ultra cold atoms are discussed.

description: Various theories have been proposed to explain the Moon's current inclined orbit. We test the viability of these theories by reconstructing the thermal-orbital history of the Moon. We build on past thermal-orbital models and incorporate the evolution of the lunar figure including a fossil figure component. Obliquity tidal heating in the lunar magma ocean would have produced rapid inclination damping, making it difficult for an early inclination to survive to the present-day. An early inclination is preserved only if the solid-body of the early Moon were less dissipative than at present. If instabilities at the Laplace plane transition were the source of the inclination, then the Moon had to recede slowly, which is consistent with previous findings of a weakly dissipative early Earth. If collisionless encounters with planetesimals up to 140 Myr after Moon formation excited the inclination, then the Moon had to migrate quickly to pass through the Cassini state transition at 33 Earth radii and reach a period of limited inclination damping. The fossil figure was likely established before 16 Earth radii to match the present-day degree-2 gravity field observations.

description: The application of modern technologies to improve educational environments is required due to a lack of workers, a decline in engineering student enrolment, and insufficient support for students who are neurodivergent. To support high education and career training for neurodiverse learners, this paper investigates the incorporation of real device operating concepts into virtual reality. Various VR implementations of common operating components were compared for immersion and usability. Functional virtual devices with operating components were integrated into a VR education platform and evaluated with both neurotypical and people with ASD. The study results demonstrate high usability for neurotypical users while emphasizing the need for improved graphical quality, user comfort, and the integration of features and techniques that enhance user movements and provide adaptable interfaces for neurodivergent users.

description: Το γένος των εντεροϊών αποτελείται από 64 μη ελυτροφόρους, μικρούς RNA ιούς, που ανήκουν στην οικογένεια Picornaviridae. Στο γένος αυτό συμπεριλαμβάνονται οι πολιοϊοί, οι ιοί Coxsackie Α και Β, οι ECHO ιοί και οι εντεροϊοί 68-71. Οι εντεροϊοί προκαλούν στον άνθρωπο ασθένειες ποικίλουσας σοβαρότητας, μπορεί όμως και να παραμείνουν ασυμπτωματικοί επί μακρόν. Η κατανομή τους είναι παγκόσμια και σε ήπια κλίματα η κυκλοφορία τους αυξάνεται στη διάρκεια του καλοκαιριού και στις αρχές του φθινοπώρου. Οι πολιοϊοί δύνανται να προκαλέσουν από παραλυτική πολιομυελίτιδα έως και αδιαφοροποίητη εμπύρετο νόσο, κυρίως κατά τη διάρκεια του καλοκαιριού. Οι Coxsackie Β ιοί, αντίστοιχα συνδέονται με πλευροδυνία, περικαρδίτιδα και μυοκαρδίτιδα, μηνιγγίτιδα και εγκεφαλίτιδα κλπ. Οι ECHO ιοί είναι οι λιγότερο παθογόνοι από τους εντεροϊούς μπορεί όμως να προκαλέσουν εντερικές λοιμώξεις, μηνιγγίτιδα κλπ. Με στόχο την μοριακή διαφοροποίηση των προτύπων στελεχών των πολιοϊών, των Coxsackie Β ιών και των ECHO ιών εφαρμόσθηκε η μέθοδος της Αλυσιδωτής Αντίδρασης της Πολυμεράσης (PCR), σε συνδυασμό με πολυμορφισμούς μήκους μετά από επώαση με περιοριστικά ένζυμα (RFLP). Για την αξιολόγηση της μεθόδου σε κλινικό επίπεδο έγινε εφαρμογή της σε ένα συνολικό αριθμό 63 κλινικών δειγμάτων. Για την PCR χρησιμοποιήθηκε το ζεύγος των κοινών, για τους εντεροϊούς, εκκινητικών μορίων UC53/UG52, τα οποία επεκτείνουν αλληλουχίες στην συντηρητική 5' μη κωδική περιοχή του γενώματος των εντεροϊών. Για την RFLP ανάλυση χρησιμοποιήθηκαν τα περιοριστικά ένζυμα Haelll, Ddel, Ncol, Hpall, Styl και Aval. Σε αντίθεση με τους Coxsackie Β και τους ECHO ιούς, οι πολιοϊοί διαφοροποιήθηκαν πλήρως τόσο μεταξύ τους, όσο και με τους υπόλοιπους εντεροϊούς. Τα ευρήματα αυτά υποδηλώνουν την τελείως διαφορετική πορεία που ακολούθησαν οι διάφορες ομάδες των εντεροϊών, εξαιτίας των διαφορετικών εξελικτικών πιέσεων που ασκήθηκαν με την πάροδο του χρόνου στους ιούς αυτούς.

description: Over a five-year period, computing methods for generating high-fidelity, fictional depictions of people and events moved from exotic demonstrations by computer science research teams into ongoing use as a tool of disinformation. The methods, referred to with the portmanteau of "deepfakes," have been used to create compelling audiovisual content. Here, I share challenges ahead with malevolent uses of two classes of deepfakes that we can expect to come into practice with costly implications for society: interactive and compositional deepfakes. Interactive deepfakes have the capability to impersonate people with realistic interactive behaviors, taking advantage of advances in multimodal interaction. Compositional deepfakes leverage synthetic content in larger disinformation plans that integrate sets of deepfakes over time with observed, expected, and engineered world events to create persuasive synthetic histories. Synthetic histories can be constructed manually but may one day be guided by adversarial generative explanation (AGE) techniques. In the absence of mitigations, interactive and compositional deepfakes threaten to move us closer to a post-epistemic world, where fact cannot be distinguished from fiction. I shall describe interactive and compositional deepfakes and reflect about cautions and potential mitigations to defend against them.

description: The massive star-forming region Mon R2 hosts the closest ultra-compact HII region that can be spatially resolved with current single-dish telescopes. We used the IRAM-30m telescope to carry out an unbiased spectral survey toward two important positions (namely IF and MP2), in order to studying the chemistry of deuterated molecules toward Mon R2. We found a rich chemistry of deuterated species at both positions, with detections of C2D, DCN, DNC, DCO+, D2CO, HDCO, NH2D, and N2D+ and their corresponding hydrogenated species and isotopologs. Our high spectral resolution observations allowed us to resolve three velocity components: the component at 10 km/s is detected at both positions and seems associated with the layer most exposed to the UV radiation from IRS 1; the component at 12 km/s is found toward the IF position and seems related to the molecular gas; finally, a component at 8.5 km/s is only detected toward the MP2 position, most likely related to a low-UV irradiated PDR. We derived the column density of all the species, and determined the deuterium fractions (Dfrac). The values of Dfrac are around 0.01 for all the observed species, except for HCO+ and N2H+ which have values 10 times lower. The values found in Mon R2 are well explained with pseudo-time-dependent gas-phase model in which deuteration occurs mainly via ion-molecule reactions with H2D+, CH2D+ and C2HD+. Finally, the [H13CN]/[HN13C] ratio is very high (~11) for the 10 km/s component, which also agree with our model predictions for an age of ~0.01-0.1 Myr. The deuterium chemistry is a good tool for studying star-forming regions. The low-mass star-forming regions seem well characterized with Dfrac(N2H+) or Dfrac(HCO+), but it is required a complete chemical modeling to date massive star-forming regions, because the higher gas temperature together with the rapid evolution of massive protostars.

description: Failure studies are important in revealing the root causes, behaviors, and life cycle of defects in software systems. These studies either focus on understanding the characteristics of defects in specific classes of systems or the characteristics of a specific type of defect in the systems it manifests in. Failure studies have influenced various software engineering research directions, especially in the area of software evolution, defect detection, and program repair. In this paper, we reflect on the conduct of failure studies in software engineering. We reviewed a sample of 52 failure study papers. We identified several recurring problems in these studies, some of which hinder the ability of the engineering community to trust or replicate the results. Based on our findings, we suggest future research directions, including identifying and analyzing failure causal chains, standardizing the conduct of failure studies, and tool support for faster defect analysis.

description: Swarm cycling has been proposed in previous researches as a novel concept for urban mobility, by adopting the "safety in number" approach, to enhance the visibility of cyclists in urban traffic and to increase the safety of cyclists. To investigate the effects of swarm cycling on the stress level of bicyclists, we conducted an experiment in an enclosed traffic training field with stressors, such as construction sites, etc. to simulate the stress situations in real traffic. A stress detection system utilizing the Galvanic Skin Response (GSR) sensor and an Android application was developed to monitor participants’ stress responses during cycling. In this research, 21 participants engaged in various cycling scenarios, including cycling alone, cycling within a swarm, and cycling in different positions within the swarm. GSR signal data were collected to quantify the number of stress peaks experienced by each participant during the rides. The data were subjected to statistical analysis to compare stress levels among the different cycling scenarios. The results of the statistical analysis indicate that swarm cycling has a positive impact on individual cyclist stress levels compared to cycling alone. However, there was no statistically significant difference in stress levels observed among different cycling positions within the swarm. This research provides insights into the potential benefits of swarm cycling as an urban mobility solution, emphasizing its positive influence on cyclist stress levels, thus encouraging the adoption of this novel concept to enhance safety and comfort for urban cyclists.

description: Recent research has shown that criminal networks have complex organizational structures, but whether this can be used to predict static and dynamic properties of criminal networks remains little explored. Here, by combining graph representation learning and machine learning methods, we show that structural properties of political corruption, police intelligence, and money laundering networks can be used to recover missing criminal partnerships, distinguish among different types of criminal and legal associations, as well as predict the total amount of money exchanged among criminal agents, all with outstanding accuracy. We also show that our approach can anticipate future criminal associations during the dynamic growth of corruption networks with significant accuracy. Thus, similar to evidence found at crime scenes, we conclude that structural patterns of criminal networks carry crucial information about illegal activities, which allows machine learning methods to predict missing information and even anticipate future criminal behavior.

description: Understanding the heating and cooling mechanisms in nearby (Ultra) luminous infrared galaxies can give us insight into the driving mechanisms in their more distant counterparts. Molecular emission lines play a crucial role in cooling excited gas, and recently, with Herschel Space Observatory we have been able to observe the rich molecular spectrum. CO is the most abundant and one of the brightest molecules in the Herschel wavelength range. CO transitions are observed with Herschel, and together, these lines trace the excitation of CO. We study Arp 299, a colliding galaxy group, with one component harboring an AGN and two more undergoing intense star formation. For Arp 299 A, we present PACS spectrometer observations of high-J CO lines up to J=20-19 and JCMT observations of $^{13}$CO and HCN to discern between UV heating and alternative heating mechanisms. There is an immediately noticeable difference in the spectra of Arp 299 A and Arp 299 B+C, with source A having brighter high-J CO transitions. This is reflected in their respective spectral energy line distributions. We find that photon-dominated regions (PDRs) are unlikely to heat all the gas since a very extreme PDR is necessary to fit the high-J CO lines. In addition, this extreme PDR does not fit the HCN observations, and the dust spectral energy distribution shows that there is not enough hot dust to match the amount expected from such an extreme PDR. Therefore, we determine that the high-J CO and HCN transitions are heated by an additional mechanism, namely cosmic ray heating, mechanical heating, or X-ray heating. We find that mechanical heating, in combination with UV heating, is the only mechanism that fits all molecular transitions. We also constrain the molecular gas mass of Arp 299 A to 3e9 Msun and find that we need 4% of the total heating to be mechanical heating, with the rest UV heating.
