description: We study the quantum dynamics of a supersymmetric squashed three-sphere by dimensionally reducing to one timelike dimension the action of D=4 simple supergravity for a Bianchi IX cosmological model. After imposition of the diffeomorphism constraints, the wave function of the Universe becomes a spinor of Spin(8,4) depending on the three squashing parameters, which satisfies Dirac, and Klein-Gordon-like, wave equations describing the propagation of a quantum spinning particle reflecting off spin-dependent potential walls. The algebra of the susy constraints and of the Hamiltonian one is found to close. One finds that the quantum Hamiltonian is built from operators that generate a 64-dimensional representation of the maximally compact sub-algebra of the rank-3 hyperbolic Kac-Moody algebra AE3. The (quartic-in-fermions) squared-mass term entering the Klein-Gordon-like equation has several remarkable properties: 1)it commutes with all the other (Kac-Moody-related) building blocks of the Hamiltonian; 2)it is a quadratic function of the fermion number NF; 3)it is negative in most of the Hilbert space. The latter property leads to a possible quantum avoidance of the singularity ("cosmological bounce"), and suggests imposing the boundary condition that the wavefunction of the Universe vanish when the volume of space tends to zero. The space of solutions is a mixture of "discrete-spectrum states" (explicitely given) and of continuous-spectrum states (parametrized by arbitrary functions entering some initial-value problem). The predominantly negative values of the squared-mass term lead to a "bottle effect" between small and large volume-Universes and to a possible reduction of the continuous spectrum to a discrete spectrum of quantum states looking like excited versions of the Planckian-size Universes described by the discrete states at fermionic levels NF=0 and 1.

description: Conventional bridge designs incorporate expansion joints at the ends of the bridge to accommodate the length changes due to environmental loading. However, expansion joints require frequent maintenance to ensure that their operation is not hindered by the collection of debris. To improve the ride quality and to reduce maintenance costs, bridge decks can be seamlessly connected to a continuous reinforced concrete pavement (CRCP). The changes in length of the seamless system, due to environmental loading, are accommodated through the formation of cracks in the concrete pavement, which expands and contracts as required. This pavement adjacent to the bridge, referred to as the transition pavement, mobilizes frictional forces at its interface with the base material upon contraction/expansion movements. As a result, this region of the pavement is subjected to significant tensile stresses during contraction and needs to be designed with sufficient longitudinal reinforcement to maintain an acceptable range of crack widths and spacing. In addition, an approach slab of varying thickness serves as the key element transmitting the longitudinal demands between the bridge and the transition pavement, while adjusting to any settlements to maintain continuity. The goal of this research was to develop an analytical framework for predicting the response of seamless bridges, which can be used to inform seamless bridge designs. Seamless bridge and pavement systems were studied for in-plane (longitudinal) deformation effects using an analytical model developed using a commercial structural analysis software. The model was used to investigate the seamless bridge design used for the Westlink Motorway 7 in Australia. A parametric study was also conducted varying four key design parameters (coefficient of friction of transition pavement with base, length of transition pavement, thickness of approach slab and transition pavement, longitudinal reinforcement in transition pavement) to study their influence on the performance of the seamless system. Based on the Australian bridge design and the insights from the parametric analyses, the design of five concrete bridges representing typical Texas structures was modified to accommodate seamless connections. The in-plane performance of the five Texas bridges was studied analytically, and the amount of longitudinal steel required in the poor-boy joints (reinforcement ratio of 1.73%) and transition slabs (reinforcement ratio of 1.45% - 0.87%) was verified based on the analytical results. The approach slab of a Texas bridge was also analyzed under out-of plane (vertical) effects caused by settlement and traffic loads. Finally, recommendations for designing seamless bridge and pavement systems are provided based on the findings of this study.

description: We derive a priori bounds on the size of the structure constants of the free Lie algebra over a set of indeterminates, relative to its Hall bases. We investigate their asymptotic growth, especially as a function of the length of the involved Lie brackets. First, using the classical recursive decomposition algorithm, we obtain a rough upper bound valid for all Hall bases. We then introduce new notions (which we call alphabetic subsets and relative foldings) related to structural properties of the Lie brackets created by the algorithm, which allow us to prove a sharp upper bound for the general case. We also prove that the length of the relative folding provides a strictly decreasing indexation of the recursive rewriting algorithm. Moreover, we derive lower bounds on the structure constants proving that they grow at least geometrically in all Hall bases. Second, for the celebrated historical length-compatible Hall bases and the Lyndon basis, we prove tighter sharp upper bounds, which turn out to be geometric in the length of the brackets. Third, we construct two new Hall bases, illustrating two opposite behaviors in the two-indeterminates case. One is designed so that its structure constants have the minimal growth possible, matching exactly the general lower bound, linked with the Fibonacci sequence. The other one is designed so that its structure constants grow super-geometrically. Eventually, we investigate asymmetric growth bounds which isolate the role of one particular indeterminate. Despite the existence of super-geometric Hall bases, we prove that the asymmetric growth with respect to each fixed indeterminate is uniformly at most geometric in all Hall bases.

description: Σκοπός της παρούσας πειραματικής μελέτης είναι α)η διερεύνηση της διοστικής εφαρμογής των χαμηλής έντασης παλμικών υπερήχων για την ευόδωση της πώρωσης των καταγμάτων και β)η κατάδειξη της δυνατότητας παρακολούθησης της εξέλιξης της πώρωσης μέσα από τη διάδοση του κύματος των χαμηλής έντασης υπερήχων. Χρησιμοποιήθηκε μοντέλο οστεοτομίας στο μέσο της διάφυσης της κνήμης σε 40 σκελετικά ώριμα πρόβατα ενώ για τη συγκράτηση της ανάταξης και τη σταθεροποίηση εφαρμόστηκε συσκευή εξωτερικής οστεοσύνθε- σης. Δύο μεταλλάκτες υπερήχων εμφυτεύτηκαν στην εστία του κατάγματος και σε επαφή με το οστό. Για τη διερεύνηση της αποτελεσματικότητας των χαμηλής έντασης υπερήχων, τα ζώα χωρίστηκαν τυχαία σε δύο ισάριθμες ομάδες, την ομάδα θεραπείας και την ομάδα ελέγχου. Τα ζώα της ομάδας θεραπείας έλαβαν αλληλουχίες ημιτονοει- δών κυμάτων διάρκειας 200 psec, κεντρικής συχνότητας 1 MHz, ρυθμού επανάληψης παλμού 1 kHz και μέσης έντασης 30 mW/cm2 για 20 min ημερησίως. Για την παρακολούθηση της εξέλιξης της πώρωσης δημιουργήθηκε μια βάση δεδομένων με κυ- ματομορφές από ανακτηθέντα σήματα υπερήχων που αφορούσαν τα 20 ζώα της ομάδας θεραπείας και 10 ζώα από την ομάδα ελέγχου. Η θυσία των ζώων έγινε την 100Π μετεγχειρητική ημέρα. Η επίδραση των υπερήχων στην ευόδωση της πώρωσης αξιολογήθηκε μετά από ακτινολογικό έλεγχο, εμβιομηχανική δοκιμασία λυγισμού τριών σημείων και μέτρηση της οστικής πυκνότητας με χρήση ποσοτικής υπολογιστικής τομογραφίας. Η ανάλυση επιβίωσης με χρήση των καμπύλών Kaplan-Meier κατέδειξε στατιστικά υψηλότερη πιθανότητα ακτινολογικής πώρωσης για τα ζώα της ομάδας θεραπείας (ρ = 0,009). Στατιστικά σημαντική διαφορά παρατηρήθηκε επίσης για την οστι- κή πυκνότητα (ρ = 0,003, Wilcoxon nonparametric test), το φορτίο θραύσης (ρ = 0,001), την ακαμψία (ρ = 0,019), το Young's Modulus (ρ = 0,043) και τη μέγιστη αντοχή (ρ = 0,051) προς όφελος των ζώων που έλαβαν θεραπεία με υπερήχους. Η ανάλυση των κυματομορφών που αντιστοιχούσαν στα ανακτηθέντα σήματα των υπερήχων κατέ- δειξε ότι η ταχύτητα διάδοσης αυτών διαμέσου του πώρου αποτελεί μια σημαντική παράμετρο με δυνατότητα πρώιμης διάκρισης μεταξύ πωρωθέντων και μη πωρωθέ- ντων οστών (η περιοχή κάτωθεν της καμπύλης λειτουργικού χαρακτηριστικού δέκτη, ROC ήταν 0,810 και 0,841 την 80η και 100η μετεγχειρητική ημέρα αντίστοιχα). Η εφαρμογή των υπερήχων τόσο για τη θεραπεία όσο και για την παρακολούθηση της πώρωσης, υποστηρίζεται από ένα ολοκληρωμένο σύστημα τηλεϊατρικής, το οποίο ενσωματώνει μια φορητή συσκευή και μια κεντρική μονάδα διαχείρησης των ασθενών.

description: We explore the ability of a recently proposed jet substructure technique, Dynamical Grooming, to pin down the properties of the Quark-Gluon Plasma formed in ultra-relativistic heavy-ion collisions. In particular, we compute, both analytically and via Monte-Carlo simulations, the opening angle $θ_g$ of the hardest splitting in the jet as defined by Dynamical Grooming. Our calculation, grounded in perturbative QCD, accounts for the factorization in time between vacuum-like and medium-induced processes in the double logarithmic approximation. We observe that the dominating scale in the $θ_g$-distribution is the decoherence angle $θ_c$ which characterises the resolution power of the medium to propagating color probes. This feature also persists in strong coupling models for jet quenching. We further propose for potential experimental measurements a suitable combination of the Dynamical Grooming condition and the jet radius that leads to a pQCD dominated observable with a very small sensitivity ($\leq 10\%$) to medium response.

description: Robots are more and more integrated into everyday environments, which makes it essential to examine how to design them so that humans are motivated and capable to interact with them. An important challenge for robotics is to determine how to design robotsthat accurately infer the human interaction partner’s goals, intentions, and emotional states, and are able to adapt to their actions in time and space. Certain aspects of this challenge can be addressed through appropriate design of robot appearance and behavior, and equipping robots with appropriate models of social cognition. Other aspects, however, arise on the human side of the “equation”, where lifelong experience with human interaction partners raises certain expectations of how verbal and nonverbal social cues are supposed to be interpreted, how actions are supposed to be coordinated and how emotional and motivational states are supposed to be communicated. If a robot meets these expectations, humans can interact with it quite intuitively, make accurate predictions regarding its actions and intentions, and interpret its social signals with ease. The question is how robots can be equipped with representations to meet these expectations. Most robots, however, violate anthropomorphic expectations in terms of their appearance, behavior and cognition, which can negatively impact performance, affect and motivation in human-robot interaction. In this paper, we discuss how the interplay between robots’ actual capabilities and human expectations regarding these capabilities imposes challenges specifically for the time- dependent aspects of social human-robot interactions.

title: Faster Might Not be Fast Enough: Improving Users’ Experience and Performance through Negative Latency
Creators: name: Henze, Niels

Publisher: name: GI
Year: 2023

description: All interactive systems have latency. Previous work showed that reducing latency has a wide range of positive effects and suggests that the benefits of reduced latency might continue even when approaching 0 ms of latency. Previouswork also developed approaches to predict users’ inputs and showed these predictions to reduce latencies’ negative effects. We propose to investigate the effects of predicting beyond a system’s latency which would essentially result in negative latency. Our recent work revealed that there is at least one task where negative latency could be beneficial. In this position paper, we discuss the potential impact and identify three challenges for future work.

description: Interference Alignment is a new solution to over- come the problem of interference in multiuser wireless com- munication systems. Recently, the Compute-and-Forward (CF) transform has been proposed to approximate the capacity of K- user Gaussian Symmetric Interference Channel and practically perform Interference Alignment in wireless networks. However, this technique shows a random behavior in the achievable sum- rate, especially at high SNR. In this work, the origin of this random behavior is analyzed and a novel precoding technique based on the Golden Ratio is proposed to scale down the fadings experiences by the achievable sum-rate at high SNR.

description: In this paper we use finite vector spaces (finite dimension, over finite fields) as a non-standard computational model of linear logic. We first define a simple, finite PCF-like lambda-calculus with booleans, and then we discuss two finite models, one based on finite sets and the other on finite vector spaces. The first model is shown to be fully complete with respect to the operational semantics of the language. The second model is not complete, but we develop an algebraic extension of the finite lambda calculus that recovers completeness. The relationship between the two semantics is described, and several examples based on Church numerals are presented.

description: The interplay between charge order and superconductivity remains one of the central themes of research in quantum materials. In the case of cuprates, the coupling between striped charge fluctuations and local electromagnetic fields is especially important, as it affects transport properties, coherence and dimensionality of superconducting correlations. Here, we study the emission of coherent terahertz radiation in single-layer cuprates of the La$_{2-x}$Ba$_x$CuO$_4$ family, for which this effect is expected to be forbidden by symmetry. We find that emission vanishes for compounds in which the stripes are quasi-static, but is activated when $c$-axis inversion symmetry is broken by incommensurate or fluctuating charge stripes, such as in La$_{1.905}$Ba$_{0.095}$CuO$_4$ and in La$_{1.845}$Ba$_{0.155}$CuO$_4$. In this case, terahertz radiation is emitted by surface Josephson plasmons, which are generally dark modes, but couple to free space electromagnetic radiation because of the stripe modulation.

Recent developments in healthcare such as the proposal of the European Health Data Space point towards a more data-driven future of diagnostics and therapy. These developments lead to new challenges, especially in how to design interaction between individuals and their personal health data. With this proposed workshop we want to stimulate discussion about these challenges from the interaction perspective and critically ask, where our health data should lie in the future and who will be owning it.

description: We present deep and high-resolution (FWHM ~ 0.4 arcsec) near-infrared (NIR) imaging observations of the NGC 7538 IRS 1-3 region (in JHK bands), and IRS 9 region (in HK bands) using the 8.2m Subaru telescope. The NIR analysis is complemented with GMRT low-frequency observations at 325, 610, and 1280 MHz, molecular line observations of H13CO+ (J=1-0), and archival Chandra X-ray observations. Using the 'J-H/H-K' diagram, 144 Class II and 24 Class I young stellar object (YSO) candidates are identified in the IRS 1-3 region. Further analysis using 'K/H-K' diagram yields 145 and 96 red sources in the IRS 1-3 and IRS 9 regions, respectively. A total of 27 sources are found to have X-ray counterparts. The YSO mass function (MF), constructed using a theoretical mass-luminosity relation, shows peaks at substellar (~0.08-0.18 Msolar) and intermediate (~1-1.78 Msolar) mass ranges for the IRS 1-3 region. The MF can be fitted by a power law in the low mass regime with a slope of Gamma ~ 0.54-0.75, which is much shallower than the Salpeter value of 1.35. An upper limit of 10.2 is obtained for the star to brown dwarf ratio in the IRS 1-3 region. GMRT maps show a compact HII region associated with the IRS 1-3 sources, whose spectral index of 0.87+-0.11 suggests optical thickness. This compact region is resolved into three separate peaks in higher resolution 1280 MHz map, and the 'East' sub-peak coincides with the IRS 2 source. H13CO+ (J=1-0) emission reveals peaks in both IRS 1-3 and IRS 9 regions, none of which are coincident with visible nebular emission, suggesting the presence of dense cloud nearby. The virial masses are approximately of the order of 1000 Msolar and 500 Msolar for the clumps in IRS 1-3 and IRS 9 regions, respectively.

title: The Role of Targeting Emotions in Healthcare Design. Report on Participatory Design Research in a Neonatal Intensive Care Unit (NICU)
Creators: name: Gaertner, Wanda
Publisher: name: GI
Year: 2023

description: This paper delves into the role of emotions in healthcare design through a participatory design study conducted in a Neonatal Intensive Care Unit (NICU). Premature births present unique challenges, and this research examines how involving stakeholders in the design process can address emotional aspects. Based on an extensive observation in a NICU, the study engages healthcare professionals, parents, and former patients through conversations, interviews, and workshops to uncover the emotional complexities of the NICU environment. The paper highlights the benefits of participation, including increased expertise, trust, empathy, and appreciation. By focusing on emotions, the paper emphasizes their impact on physical well-being and how they shape responses. The paper concludes that a collaborative design approach fosters understanding and identifies key design points such as addressing uncertainty, promoting intimacy, mitigating helplessness, rectifying structural issues, and enhancing affection. Ultimately, it advocates for designing healthcare spaces that positively influence emotions for patients, families, and healthcare providers.

This critical setting yields hazardous circumstances that could harm human beings. Thus, building such systems with strong assurances of compliance with requirements, domain-specific standards and regulations is of greatest importance. Only few scale impact has been reported so far for such systems since much work remains to manage possible risks. We identify emerging problems in this context and then we report our vision, as well as the progress of our multidisciplinary research team composed of software/systems, and mechatronics engineers to develop a risk-driven assurance process for CAISs.

The aim of this thesis is to investigate control issues in photovoltaic system as the design of PV plants, in the present-day evolving scenario, is not completely defined. This company has pointed out a great interest to explore new control techniques that can have static and dynamic performance better than the existing techniques implemented in its systems, to analyze new scenarios due to the insertion of the Distributed Power Generating Systems (DPGSs) into the grid and to optimize the current methods to extract power from the PV source with the final goal to increase the performance of the PV systems at any level, system, grid and circuit. Hence, the starting points have been highlighted from the industry but they have also a great impact on the scientific and technologic fields. ...[edited by Author]

description: Time perception is an integral aspect of human experience and has numerous implications for the communication between humans and computers. When interacting with computers, user experience is often compromised by non-optimal latency and temporal misperception. In this workshop, we gather scientists from diverse research fields (including Human-Computer Interaction, Psychology, Computer Sciences, and Design) to discuss the possibilities of altering the temporal experience of users of interactive systems and to reflect on the potential benefits and risks of such a systematic manipulation. This workshop aims to foster a shared understanding of imminent research questions at the intersection of time perception and HCI research and to identify strategies for tackling them in collaborative projects.
title: Conflict in a Warming World: How Climate Shocks Impact Rebel Demands and Peace Agreement Outcomes

description: As climate change becomes more severe and its effects more frequently observed, its impact on global conflict is increasingly important. Climate shocks, acting as threat multipliers, worsen vulnerabilities in conflict areas, increasing demands for scarce resources like water and land. This report explores how climate shocks influence rebel demands and violence, and whether these changes are reflected in peace agreements. Not only are the demands for redistribution or influence on management of resources increasing, but the salience of these demands grows for all sides in the conflict, making these topics more likely to be added to the core topics of peace talks. Using geospatial climatological and conflict data, this study tests two main hypotheses: 1) climate shocks will increase rebel demands for climate-related resources, and 2) these increased demands will lead to more provisions for water, land, and resources in peace agreements. The research employs difference-in-differences and panel linear regression methods that allow us to isolate the effects of climate shocks on rebel activity and assess whether these demands are addressed in peace agreements. The findings provide key insights into how climate pressures shape conflict and how we can expect conflicts to evolve in a future of worsening climatic conditions. It is reasonable to assume that any effects found now will be smaller than what we can expect under unmitigated global warming. Therefore, the effects observed with existing data are substantively significant, as they likely represent a conservative estimate of future impacts. These insights are crucial for understanding the dynamics of conflict and for informing conflict resolution strategies in a warming world.

description: Non-negative matrix factorization with transform learning (TL-NMF) is a recent idea that aims at learning data representations suited to NMF. In this work, we relate TL-NMF to the classical matrix joint-diagonalization (JD) problem. We show that, when the number of data realizations is sufficiently large, TL-NMF can be replaced by a two-step approach -- termed as JD+NMF -- that estimates the transform through JD, prior to NMF computation. In contrast, we found that when the number of data realizations is limited, not only is JD+NMF no longer equivalent to TL-NMF, but the inherent low-rank constraint of TL-NMF turns out to be an essential ingredient to learn meaningful transforms for NMF.

description: Despite the merits of public and social media in private and professional spaces, citizens and professionals are increasingly exposed to cyberabuse, such as cyberbullying and hate speech. Thus, Law Enforcement Agencies (LEA) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberabuse. However, their tasks are getting more complex by the increasing amount and varying quality of information disseminated into public channels. Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYLENCE project, which seeks to design strategies and tools for cross-media reporting, detection, and treatment of cyberbullying and hatespeech in investigative and law enforcement agencies. Second, it identifies and elaborates seven research challenges with regard to the monitoring, analysis and communication of cyberabuse in LEAs, which serve as a starting point for in-depth research within the project.

description: High-entropy-alloy (HEA) superconductors are a new class of disordered superconductors. In this study, we investigate the robustness of superconducting states in HEA-type metal telluride (MTe; M = Ag, In, Sn, Pb, Bi) under high pressure. PbTe exhibits a structural transition from a NaCl-type to an orthorhombic Pnma structure at low pressures, and further transitions to a CsCl-type structure at high pressures. When the superconductivity of the CsCl-type PbTe is observed, it is found that its superconducting transition temperature (Tc) decreases with pressure. However, in the HEA-type AgInSnPbBiTe5, Tc is almost independent of pressure, for pressures ranging from 13.0 to 35.1 GPa. This trend is quite similar to that observed in an HEA superconductor (TaNb)0.67(HfZrTi)0.33, which shows that the robustness of superconductivity to external pressure is a universal feature in HEA-type superconductors. To clarify the effects of the modification of the configurational entropy of mixing on the crystal structure, superconducting states, and electronic structure of MTe, electrical resistance measurements, synchrotron X-ray diffraction, and synchrotron X-ray absorption spectroscopy with partial fluorescence mode (PFY-XAS) for three MTe polycrystalline samples of PbTe, AgPbBiTe3, and AgInSnPbBiTe5 with different configurational entropies of mixing at the M site were performed.

description: Since more than two years, the First G-APD Cherenkov Telescope (FACT) is operating successfully at the Canary Island of La Palma. Apart from its purpose to serve as a monitoring facility for the brightest TeV blazars, it was built as a major step to establish solid state photon counters as detectors in Cherenkov astronomy. The camera of the First G-APD Cherenkov Telesope comprises 1440 Geiger-mode avalanche photo diodes (G-APD aka. MPPC or SiPM) for photon detection. Since properties as the gain of G-APDs depend on temperature and the applied voltage, a real-time feedback system has been developed and implemented. To correct for the change introduced by temperature, several sensors have been placed close to the photon detectors. Their read out is used to calculate a corresponding voltage offset. In addition to temperature changes, changing current introduces a voltage drop in the supporting resistor network. To correct changes in the voltage drop introduced by varying photon flux from the night-sky background, the current is measured and the voltage drop calculated. To check the stability of the G-APD properties, dark count spectra with high statistics have been taken under different environmental conditions and been evaluated. The maximum data rate delivered by the camera is about 240 MB/s. The recorded data, which can exceed 1 TB in a moonless night, is compressed in real-time with a proprietary loss-less algorithm. The performance is better than gzip by almost a factor of two in compression ratio and speed. In total, two to three CPU cores are needed for data taking. In parallel, a quick-look analysis of the recently recorded data is executed on a second machine. Its result is publicly available within a few minutes after the data were taken. [...]

description: Over the past thirty years, researchers have highlighted the role played by a class of proteins or polypeptides that forms pathogenic amyloid aggregates in vivo, including i) the amyloid Abeta peptide, which is known to form senile plaques in Alzheimer's disease; ii) alpha-synuclein, responsible for Lewy body formation in Parkinson's disease and iii) IAPP, which is the protein component of type 2 diabetes-associated islet amyloids. These proteins, known as intrinsically disordered proteins (IDPs), are present as highly dynamic conformational ensembles. IDPs can partially (mis) fold into (dys) functional conformations and accumulate as amyloid aggregates upon interaction with other cytosolic partners such as proteins or lipid membranes. In addition, an increasing number of reports link the toxicity of amyloid proteins to their harmful effects on membrane integrity. Still, the molecular mechanism underlying the amyloidogenic proteins transfer from the aqueous environment to the hydrocarbon core of the membrane is poorly understood. This review starts with a historical overview of the toxicity models of amyloidogenic proteins to contextualize the more recent lipid-chaperone hypothesis. Then, we report the early molecular-level events in the aggregation and ion-channel pore formation of Abeta, IAPP, and alpha-synuclein interacting with model membranes, emphasizing the complexity of these processes due to their different spatial-temporal resolutions. Next, we underline the need for a combined experimental and computational approach, focusing on the strengths and weaknesses of the most commonly used techniques. Finally, the last two chapters highlight the crucial role of lipid-protein complexes as molecular switches among ion-channel-like formation, detergent-like, and fibril formation mechanisms and their implication in fighting amyloidogenic diseases.
