description: In recent years, digital technologies have significantly reshaped the economy and society, impacting all sectors of activity and the daily lives of Europeans. The digitalization of the European economy has compelled entities across the board to adapt their internal processes to address emerging needs. This paper explores how European SMEs can leverage recent advancements in Large Language Models (LLMs) or Generative Pre-trained Transformers (GPT), such as ChatGPT, GEMINI, or other tools of Artificial Intelligence (AI), to achieve this objective, considering their constraints in terms of human and financial resources compared to larger enterprises. Our focus is on PRINTRIA, a small Portuguese company that utilized these resources to overcome internal skill shortages and execute system migrations without external reliance. The findings highlight the practical steps taken, the benefits realized, and the challenges faced by PRINTRIA, demonstrating the potential of AI tools in supporting SMEs. Furthermore, the study concludes that investing in digital skills and leveraging AI technologies can significantly enhance operational resilience, efficiency, and competitive advantage for SMEs.

description: We examine high signal to noise XMM-Newton European Photon Imaging Camera (EPIC) and Reflection Grating Spectrometer (RGS) observations to determine the physical characteristics of the gas in the cool core and outskirts of the nearby rich cluster A3112. The XMM-Newton Extended Source Analysis Software data reduction and background modeling methods were used to analyze the XMM- Newton EPIC data. From the EPIC data we find that the iron and silicon abundance gradients show significant increase towards the center of the cluster while the oxygen abundance profile is centrally peaked but has a shallower distribution than that of iron. The X-ray mass modeling is based on the temperature and deprojected density distributions of the intra-cluster medium determined from EPIC observations. The total mass of A3112 obeys the M-T scaling relations found using XMM-Newton and Chandra observations of massive clusters at R500. The gas mass fraction f_gas= 0.149^{+0.036}_{-0.032} at R500, is consistent with the seven-year WMAP results. The comparisons of line fluxes and flux limits on the Fe XVII and Fe XVIII lines obtained from high resolution RGS spectra indicate that there is no spectral evidence for cooler gas associated with the cluster with temperature below 1.0 keV in the central <38" (\sim 52 kpc) region of A3112. High resolution RGS spectra also yield an upper limit to the turbulent motions in compact core of A3112 (206 km/s). We find that the energy contribution of turbulence to total energy is less than 6 per cent. This upper limit is consistent with the amount of energy contribution measured in recent high resolution simulations of relaxed galaxy clusters.

description: Recently it has been shown that the non-local correlations needed for measurement based quantum computation (MBQC) can be revealed in the ground state of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model involving nearest neighbor spin-3/2 interactions on a honeycomb lattice. This state is not singular but resides in the disordered phase of ground states of a large family of Hamiltonians characterized by short-range-correlated valence bond solid states. By applying local filtering and adaptive single particle measurements we show that most states in the disordered phase can be reduced to a graph of correlated qubits that is a scalable resource for MBQC. At the transition between the disordered and Neel ordered phases we find a transition from universal to non-universal states as witnessed by the scaling of percolation in the reduced graph state.

Publisher: name: ICIEMC Proceedings
Year: 2025

description: Balanced scorecard (BSC) has seen intensified scrutiny from academia in terms of its ability and effectiveness in driving sustainability goals. Additionally, the wider topic of organizational social impact measurement has seen similar debates around what can be considered a proper outlet for performance and control tracking. It also remained unresolved the need for a sustainability and/or social impact measurement solution that is standardizable, consistent, effective in achieving its goals and integrated in the corporate strategy. This paper takes on a journey of systematic literature review aiming to address whether a social impact measurement scheme can be effectively incorporated into existing performance monitoring & control systems. Following this approach, it investigates the space created around Balanced Scorecard (BSC), sustainability -as a benchmark in assessing their ‘co-existence’- and social value. The aim is to answer 2 research questions: (1) What are the missing links when it comes to achieving an integrated and standardizable approach in corporate sustainability and social impact measurement? (2) Is it effective to use BSC based design to monitor and track the corporate sustainability and/or social impact of an organization? This study analyzed 69 papers published between 2010 and 2024 and indexed on ISI Web of Science - Current Contents. These papers underwent comprehensive analysis with the help of Endnote and NVivo. Subsequently a refined sample of 40 papers, directly related to the research questions, was isolated. The findings of this study show that although existing infrastructures for performance management (i.e BSC) could be redesigned so that they can incorporate additional social impact measures, there are significant limitations in terms of effectiveness. It suggests that given the complexities of a social impact measurement endeavor, essential foundational elements of effective measurement and integration need to be addressed first. This implies having a tailored approach in the setup of performance tools able to effectively support the social impact measures endeavor.

description: Individuals in brokerage positions are vital when further developing complex organizations with multiple subgroups only loosely coupled to each other. Network theorists have conceptualized an individual’s brokerage as the degree to which a person occupies a bridging position between disconnected others. Research outside the school context has indicated for quite some time that an individual’s social capital in the form of brokerage is positively associated with professional development—not only on a collective but also on an individual level. Schools are without any doubt complex organizations with multiple loosely connected stakeholders involved when further developing their educational practice. Thus, it is not surprising that in recent years, the concept of brokerage has gained interest in research on school improvement as well. Up to now, in school improvement research brokerage has been operationalized in different ways: as individuals’ formal entitlement to act as intermediaries (formal brokerage), their position within a social network (structural brokerage), or their behavior when linking disconnected groups of staff members (behavioral brokerage). As these perspectives have often been examined separately, this study, as a first step, aimed to simultaneously assess school staff members’ formal, structural, and behavioral brokerage, and examine their degree of interrelatedness. In a second step, associations of brokerage with professional well-being were analyzed. Even though there is evidence for the positive impact of brokerage on professional development, only little is known about its associations with professional well-being. In a third step, interaction effects were examined when formal brokerage is congruent or incongruent with other facets of brokerage. Based on a sample of 1,316 school staff members at 51 primary schools in the German-speaking part of Switzerland, we conducted both bivariate correlational and multiple-group structural equation modeling analyses. The findings revealed that formal, structural, and behavioral brokerage are interrelated facets. However, formal entitlement did not determine either structural position or behavior. Moreover, brokerage within schools was only partially related to professional well-being. In the discussion section, the study’s key contributions and practical implications are presented in detail.

description: Ultra-high energy cosmic rays (UHECRs) are atomic nuclei with energies over ten million times energies accessible to human-made particle accelerators. Evidence suggests that they originate from relatively nearby extragalactic sources, but the nature of the sources is unknown. We develop a multilevel Bayesian framework for assessing association of UHECRs and candidate source populations, and Markov chain Monte Carlo algorithms for estimating model parameters and comparing models by computing, via Chib's method, marginal likelihoods and Bayes factors. We demonstrate the framework by analyzing measurements of 69 UHECRs observed by the Pierre Auger Observatory (PAO) from 2004-2009, using a volume-complete catalog of 17 local active galactic nuclei (AGN) out to 15 megaparsecs as candidate sources. An early portion of the data ("period 1," with 14 events) was used by PAO to set an energy cut maximizing the anisotropy in period 1; the 69 measurements include this "tuned" subset, and subsequent "untuned" events with energies above the same cutoff. Also, measurement errors are approximately summarized. These factors are problematic for independent analyses of PAO data. Within the context of "standard candle" source models (i.e., with a common isotropic emission rate), and considering only the 55 untuned events, there is no significant evidence favoring association of UHECRs with local AGN vs. an isotropic background. The highest-probability associations are with the two nearest, adjacent AGN, Centaurus A and NGC 4945. If the association model is adopted, the fraction of UHECRs that may be associated is likely nonzero but is well below 50%. Our framework enables estimation of the angular scale for deflection of cosmic rays by cosmic magnetic fields; relatively modest scales of $\approx\!3^{\circ}$ to $30^{\circ}$ are favored. Models that assign a large fraction of UHECRs to a single nearby source (e.g., Centaurus A) are ruled out unless very large deflection scales are specified a priori, and even then they are disfavored. However, including the period 1 data alters the conclusions significantly, and a simulation study supports the idea that the period 1 data are anomalous, presumably due to the tuning. Accurate and optimal analysis of future data will likely require more complete disclosure of the data.

The ecohydrology of coupled surface water - groundwater systems
Creators: name: Neumann, Natasha Niki
Publisher: name: University of British Columbia
Year: 2013

description: Our ability as a society to responsibly manage water resources for both humans and the environment relies on accurate predictive models. Current hydrologic models are unable to simulate important biogeochemical reactions that occur in systems where surface water and groundwater are coupled, where flowpaths alternate between highly contrasting surface and subsurface environments. Informed and responsible aquatic ecosystem management requires an understanding of the complex feedbacks between ecological properties and functions in ponds, streams, rivers and lakes, and the catchment hydrological processes affecting the quantity and quality of water entering aquatic systems. The types of flowpaths and the duration of water flow in a catchment determine the physical and chemical characteristics of water entering aquatic systems, which in turn affect the natural range of ecological properties and functions. The primary objective of this work was to create capacity for better prediction of the impacts of hydrologic variability on aquatic ecosystems. Three field studies were undertaken, representing different aquatic ecosystems (a river, stream, and lake) and different ecological functions (salmon spawning habitat use, wetted habitat availability, and nutrient cycling) occurring at different scales (point, regional and catchment). For each study, a combined hydrochemical and hydrometric approach was developed to describe the variability in flowpaths over space and time, and to quantify or infer the relative transit times of water received from the catchments. Water exiting a catchment is the convergence of many different flowpaths with many different transit times. It was found that the selected ecological processes could be discussed in terms of transit time, specifically the ratio of long to short transit times of water delivered to an aquatic system. These results were used to propose a conceptual model capable of predicting the impacts of climatic variability and change and anthropogenic activities on aquatic ecosystems through their effects on hydrologic processes. Further work is needed to quantify the transit time ratio and test the efficacy of the predictive model.

description: We study coupled axial and polar axisymmetric oscillations of a neutron star endowed with a strong magnetic field, having both poloidal and toroidal components. The toroidal component of the magnetic field is driving the coupling between the polar and axial oscillations. The star is composed of a fluid core as well as a solid crust. Using a two dimensional general relativistic simulation and a magnetic field B = 10^16 G, we study the change in the polar and axial spectrum caused by the coupling. We find that the axial spectrum suffers a dramatic change in its nature, losing its continuum character. In fact, we find that only the 'edges' of the continua survive, generating a discrete spectrum. As a consequence the crustal frequencies, that in our previous simulation could be absorbed by the continua, if they were embedded inside it, are now long living oscillations. They may lose their energy only in the very special case that they are in resonance with the 'edges' of the continua.

description: The notion of an apparent horizon (AH) in a collapsing object can be carried over from the Lema\^ıtre -- Tolman (L--T) to the quasispherical Szekeres models in three ways: 1. Literally by the definition -- the AH is the boundary of the region, in which every bundle of null geodesics has negative expansion scalar. 2. As the locus, at which null lines that are as nearly radial as possible are turned toward decreasing areal radius $R$. These lines are in general nongeodesic. The name "absolute apparent horizon" (AAH) is proposed for this locus. 3. As the boundary of a region, where null \textit{geodesics} are turned toward decreasing $R$. The name "light collapse region" (LCR) is proposed for this region (which is 3-dimensional in every space of constant $t$); its boundary coincides with the AAH. The AH and AAH coincide in the L--T models. In the quasispherical Szekeres models, the AH is different from (but not disjoint with) the AAH. Properties of the AAH and LCR are investigated, and the relations between the AAH and the AH are illustrated with diagrams using an explicit example of a Szekeres metric. It turns out that an observer who is already within the AH is, for some time, not yet within the AAH. Nevertheless, no light signal can be sent through the AH from the inside. The analogue of the AAH for massive particles is also considered.

title: Time-Invariant Control in LQ Optimal Tracking: An Alternative to Output Regulation
Creators: name: Bernhard, Sebastian
Publisher: name: Elsevier
Year: 2021

description: We propose a new time-invariant control for linear quadratic tracking problems with references and disturbances generated by linear exo-systems. The control consists of a static feedback and a static pre-filter similar as in output regulation theory (ORT). Instead of forcing the tracking error to converge to zero, a tolerated steady-state error is balanced against the necessary input-energy via a quadratic cost. For the first time in this context, we deduce a time-invariant control from algebraic equations such that necessary optimality conditions are satisfied on infinite horizons. Then, we prove strong optimality for bounded exo-system states. Hence, any other steady-state solution will lead to infinite additional cost. On finite horizons and for arbitrary exo-systems, we prove that our control is an agreeable plan as it approximates the computational expensive, time-varying optimal control of any suitably large horizon. Since our control applies for any initial conditions of the plant and the exo-system, it is well suited for a practical resource-efficient implementation. In this regard, a presented algorithm allows for an easy to carry out control design. Finally, an industrial application indicates the unified treatment of square, under- and over-actuated systems by our approach in contrast to ORT.
Understanding AI's Role in Shaping Consumer Choices
Creators: name: Arantes, Luzia
Publisher: name: ICIEMC Proceedings
Year: 2025

description: The rapid evolution of artificial intelligence (AI) has substantially transformed marketing and the way consumers make decisions. This study investigates the impact of transparency and perceived control on the acceptance of personalized recommendations made by AI systems. The research was conducted with 81 participants through online questionnaires collected between March and April 2024. The structural model used analyzed the relationships between transparency, perceived control, perception of AI, and consumers' purchasing decisions. The results reveal that transparency and perceived control act as critical mediators in the relationship between the perception of AI and acceptance of personalized recommendations, influencing consumer trust as well as their concerns about privacy and ethics in the use of data. The findings highlight that clear communication about how AI operates and offers recommendations can increase the perception of transparency, giving consumers a deeper understanding of the processes involved. At the same time, giving users more control over personalized preferences can lead to greater engagement and trust in AI-generated recommendations. Thus, companies looking to deploy personalized recommendation systems should focus on developing strategies that emphasize transparency and offer significant control to the user. The findings indicate that such approaches can significantly contribute to increasing the acceptance of personalized recommendations while addressing ethical and privacy concerns in the use of data.

description: We present a space-time generalization of the known spatial (monochromatic) wave vortex beams carrying intrinsic orbital angular momentum (OAM) along the propagation direction. Generic spatio-temporal vortex beams are polychromatic and can carry intrinsic OAM at an arbitrary angle to the mean momentum. Applying either (i) a transverse wave-vector shift or (ii) a Lorentz boost to a monochromatic Bessel beam, we construct a family of either (i) time-diffracting or (ii) non-diffracting spatio-temporal Bessel beams, which are exact solutions of the Klein-Gordon wave equations. The proposed spatio-temporal OAM states are able to describe either photon or electron vortex states (both relativistic and nonrelativistic), and can find applications in particle collisions, optics of moving media, quantum communications, and astrophysics.

As an application, we show that Rado systems are solvable in C-sets.

description: Thirty years ago Australian researchers led the development of language and content integration in schools, advocating systematic teaching of language across the curriculum to meet the needs of English as an additional language (EAL) students. However, despite significant improvements in initial teacher education, targeted professional development and language-specific curriculum and assessment, this paper suggests that secondary teachers have gained only a superficial understanding of the language knowledge necessary to teach EAL students. Drawing on questionnaires, interviews, and observations, this case study of two secondary schools in Sydney reveals the majority of teachers report their perspectives and experiences of good teaching have equipped them with a repertoire of sufficient strategies to meet EAL needs, and they see little difference between teaching EAL and learners with low levels of literacy. This paper concludes a renewed focus on integrating language and content teaching and partnership models of professional learning and evaluation are needed.

description: We present a new systematic method to construct Abelian functions on Jacobian varieties of plane, algebraic curves. The main tool used is a symmetric generalisation of the bilinear operator defined in the work of Baker and Hirota. We give explicit formulae for the multiple applications of the operators, use them to define infinite sequences of Abelian functions of a prescribed pole structure and deduce the key properties of these functions. We apply the theory on the two canonical curves of genus three, presenting new explicit examples of vector space bases of Abelian functions. These reveal previously unseen similarities between the theories of functions associated to curves of the same genus.

description: Despite the rapid growth of implementation science, economic evaluations of implementation strategies in health and social care remain limited, with fewer than 10% of studies including comparative economic analyses. Existing reviews have highlighted the scarcity of economic evaluations and the lack of standardized methodologies for assessing implementation costs and reporting them alongside health and implementation outcomes. Given the growing need for cost-effective strategies to enhance the adoption of evidence-based interventions, a comprehensive understanding of economic evaluations of implementation strategies is essential. This scoping review aims to identify, compare, and assess the methodological quality of economic evaluations of implementation strategies in health and social care settings.

Twisted vertex algebras, bicharacter construction and boson-fermion correspondences

description: The boson-fermion correspondences are an important phenomena on the intersection of several areas in mathematical physics: representation theory, vertex algebras and conformal field theory, integrable systems, number theory, cohomology. Two such correspondences are well known: the types A and B (and their super extensions). As a main result of this paper we present a new boson-fermion correspondence, of type D-A. Further, we define a new concept of twisted vertex algebra of order $N$, which generalizes super vertex algebra. We develop the bicharacter construction which we use for constructing classes of examples of twisted vertex algebras, as well as for deriving formulas for the operator product expansions (OPEs), analytic continuations and normal ordered products. By using the underlying Hopf algebra structure we prove general bicharacter formulas for the vacuum expectation values for three important groups of examples. We show that the correspondences of type B, C and D-A are isomorphisms of twisted vertex algebras.
description: Intermediate version---shorter than version 2, but longer than the version which is to appear in the Journal of Mathematical Physics. The name of the new correspondence related to the bosonization on the single neutral fermion Fock space is changed to "boson-fermion correspondence of type D-A". Part of the definition of a twisted vertex algebra revised. Minor changes to language, typos corrected

Light-based mapping of mouse sensorimotor cortex
Creators: name: Harrison, Thomas Clarke
Publisher: name: University of British Columbia
Year: 2013

description: The motor cortex controls voluntary, skilled movements. It possesses a basic somatotopic organization, but its fine structure remains controversial. Although the reorganization of motor cortex after brain injury is believed to be a critical part of behavioral recovery, our understanding of this process has been constrained by technical limitations. Conventional methods for mapping the motor cortex rely on the insertion of intracortical stimulating electrodes into the brain. We developed a new method for light-based motor mapping that is faster, less invasive, and better suited to repeated mapping in both acute and longitudinal studies. Using this technique, we identified a functional subdivision of the mouse forelimb motor representation according to the direction of movement. Pharmacological and anatomical experiments revealed that the expression of complex movements requires the intact function of the intracortical circuitry, whereas the basic topography of movement in motor cortex may arise primarily from the arrangement of output projections. We also refined methods for intrinsic optical signal sensory imaging, which can be combined with light-based motor mapping to obtain a more complete map of sensorimotor cortex. Performing light-based mapping of sensorimotor cortex for weeks before and after targeted photothrombotic stroke allowed us to monitor cortical reorganization on an unprecedented timescale. We found that if forelimb somatosensory cortex was destroyed by targeted stroke, the forelimb motor cortex was able to incorporate a reorganized sensory map. As a consequence of this increased integration of sensory and motor function after stroke, however, the structure of the motor map was altered, evidenced by a decrease in spatial autocorrelation. Strokes in motor cortex caused increased motor output in peri-infarct cortex, but had no effect on the location or sensitivity of the forelimb somatosensory representation. Light-based motor mapping has provided new insights into both the functional organization of motor cortex and its capacity for spontaneous reorganization after stroke.

Futurism and Experimentation in Italian Theater in the Late 20th Century
Creators: name: Bentoglio, Alberto
Publisher: name: Università degli Studi di Milano
Year: 2012

description: This paper aims to understand whether and to which extent the Futurism theory of theatre and its practices have influenced the Italian contemporary scene. Common opinion still has it that Futurism has left little to no legacy in the Italian theatre, and we cannot properly speak of neo-futurism or of an active Futurist avant-garde. Nonetheless, taking a closer look at some of most significant figures in Italian experimental theatre (for example, Ivrea Manifesto’s project, Carmelo Bene, Socìetas Raffaello Sanzio) this paper aims to underline the many elements that trace back to Futurist’s theatre, suggesting the need to re-read futurist artistic experiences – at least in the field of performing arts – as constructive practices aimed at the building of a new kind of theatre.

«Un mulino che macina il testo». Parola e immagine nel teatro di Tadeusz Kantor
Creators: name: Conte, Pietro
Publisher: name: Università degli Studi di Milano
Year: 2012

description: Alla poliedrica attività di regista, pittore e ideatore di performance, Kantor ha saputo accostare, lungo tutto l’arco della sua esistenza, una compatta – seppur non certo sistematica – teoria del teatro. Il saggio si concentra su uno dei maggiori leitmotiv della riflessione kantoriana, relativo al millenario problema del rapporto tra parola e immagine, tra testo e rappresentazione, tra dramma e messa in scena.

description: We examine in more detail specific models which yield a little rip cosmology, i.e., a universe in which the dark energy density increases without bound but the universe never reaches a finite-time singularity. We derive the conditions for the little rip in terms of the inertial force in the expanding universe and present two representative models to illustrate in more detail the difference between little rip models and those which are asymptotically de Sitter. We derive conditions on the equation of state parameter of the dark energy to distinguish between the two types of models. We show that coupling between dark matter and dark energy with a little rip equation of state can alter the evolution, changing the little rip into an asymptotic de Sitter expansion. We give conditions on minimally-coupled phantom scalar field models and on scalar-tensor models that indicate whether or not they correspond to a little rip expansion. We show that, counterintuitively, despite local instability, a little-rip cosmology has an infinite lifetime.
