description: The isospin dependence of incompressibility is investigated in the Skyrme Hartree-Fock (SHF) and relativistic mean field (RMF) models. The correlations between the nuclear matter incompressibility and the isospin dependent term of the finite nucleus incompressibility is elucidated by using the Thomas-Fermi approximation. The Coulomb term is also studied by using various different Skyrme Hamiltonians and RMF Lagrangians. The symmetry energy coefficient of incompressibility is extracted to be K_τ=-(500\pm50) MeV from the recent experimental data of isoscalar giant monopole resonances (ISGMR) in Sn isotopes. Microscopic HF+random phase approximation (RPA) calculations are also performed with Skyrme interactions for ^{208}Pb and Sn isotopes to study the strength distributions of ISGMR. .

description: The horror pleni that Dorfles identifies with «Too much information, too many images, too many noises» is equivalent to the “Tzunami of information” that, according to Floridi, has invested the company in the last decade. Hypertrophy of the sign for the first, infosphere and onlife are the terms from which to start working on the second. A fourth revolution in which the expression onlife defines the new perimeter of our daily activities and ICT technologies, among these the IoT, increasingly configure the environment we live in and influence the processes related to maintaining quality in time and to life cycle assessment. It is not a new theme; the approaches brought about by digital transformation have been innovated. Equally worthy of challenge are the new problems and the new complexities related to interoperability and Big Data Analytics.

description: Recently, two-dimensional ferromagnetism in the family of Chromium compounds $\rm CrXTe_3 (X=Si, Ge)$ has attracted a broad research interest. Despite the structural similarity in $\rm CrTe_6$ octahedra, the size effect of inserted Ge or Si dimer contributes to significant differences in magnetism. Here, we report a new quaternary van der Waals ferromagnetic material $\rm CrGe_δSi_{1-δ}Te_3$ synthesized by flux method. Ge substitution in Si site results in the lattice expansion, further increasing the Curie temperature and reducing the magnetic anisotropy. The critical behavior of $\rm Cr_{0.96}Ge_{0.17}Si_{0.82}Te_3$ has been studied by specific heat as well as magnetization measurements. And the extracted critical exponents are self-consistent and well-obeying the scaling laws, which are closer to the 2D Ising model with interaction decaying as $J(r)\approx r^{-3.44}$.

description: This paper analyses images from 43 to 340 GHz to trace the structure of the Source I disk in Orion-KL with $\sim$12 AU resolution. The data reveal an almost edge-on disk with an outside diameter $\sim$ 100 AU which is heated from the inside. The high opacity at 220-340 GHz hides the internal structure and presents a surface temperature $\sim$500 K. Images at 43, 86 and 99 GHz reveal structure within the disk. At 43 GHz there is bright compact emission with brightness temperature $\sim$1300 K. Another feature, most prominent at 99 GHz, is a warped ridge of emission. The data can be explained by a simple model with a hot inner structure, seen through cooler material. A wide angle outflow mapped in SiO emission ablates material from the interior of the disk, and extends in a bipolar outflow over 1000 AU along the rotation axis of the disk. SiO $v=0$ $J=5-4$ emission appears to have a localized footprint in the warped ridge. These observations suggest that the ridge is the working surface of the disk, and heated by accretion and the outflow. The disk structure may be evolving, with multiple accretion and outflow events. We discuss two sources of variability: 1) variable accretion onto the disk as Source I travels through the filamentary debris from the BN-Source I encounter $\sim$550 yr ago; and 2) episodic accretion from the disk onto the protostar which may trigger multiple outflows. The warped inner disk structure is direct evidence that SrcI could be a binary experiencing episodic accretion.

description: The success of the strategies for safeguarding, preserving and maintaining the precious assets of the huge European Cultural Heritage still represents a challenge that many countries tackle with limited or inadequate actions or systems, despite the fact that the international community is now aware of the serious risks endangering its heritage. The nature of this fragile context requires the knowledge of data and information other than the technical and construction characteristics of buildings. The paper describes an innovative management tool for inspection and maintenance of historical and monumental buildings, developed within the Horizon 2020 European research project INCEPTION (Inclusive Cultural Heritage in Europe through 3D semantic modelling).

description: The wide diffusion of cheap, small, and portable sensors integrated in an unprecedented large variety of devices and the availability of almost ubiquitous Internet connectivity make it possible to collect an unprecedented amount of real time information about the environment we live in. These data streams, if properly and timely analyzed, can be exploited to build new intelligent and pervasive services that have the potential of improving people's quality of life in a variety of cross concerning domains such as entertainment, health-care, or energy management. The large heterogeneity of application domains, however, calls for a middleware-level infrastructure that can effectively support their different quality requirements.

In this thesis we study the challenges related to the provisioning of differentiated quality-of-service (QoS) during the processing of data streams produced in pervasive environments. We analyze the trade-offs between guaranteed quality, cost, and scalability in streams distribution and processing by surveying existing state-of-the-art solutions and identifying and exploring their weaknesses. We propose an original model for QoS-centric distributed stream processing in data centers and we present Quasit, its prototype implementation offering a scalable and extensible platform that can be used by researchers to implement and validate novel QoS-enforcement mechanisms. To support our study, we also explore an original class of weaker quality guarantees that can reduce costs when application semantics do not require strict quality enforcement. We validate the effectiveness of this idea in a practical use-case scenario that investigates partial fault-tolerance policies in stream processing by performing a large experimental study on the prototype of our novel LAAR dynamic replication technique.

Our modeling, prototyping, and experimental work demonstrates that, by providing data distribution and processing middleware with application-level knowledge of the different quality requirements associated to different pervasive data flows, it is possible to improve system scalability while reducing costs.

description: Effects of strong final-state interactions in the superscaling properties of neutral-current quasielastic neutrino cross sections are investigated using the Relativistic Impulse Approximation as guidance. First- and second-kind scaling are analyzed for neutrino beam energies ranging from 1 to 2 GeV for the cases of 12C, 16O and 40Ca. Different detection angles of the outgoing nucleon are considered in order to sample various nucleon energy regimes. Scaling of the second kind is shown to be very robust. Validity of first-kind scaling is found to be linked to the kinematics of the process. Superscaling still prevails even in the presence of very strong final-state interactions, provided that some kinematical restrains are kept, and the conditions under which superscaling can be applied to predict neutral-current quasielastic neutrino scattering are determined.

description:
Although Black women's perfectionist tendencies may mirror other students’, they experience unique academic pressures and expectations due to the intersections of racism and sexism in education. We used stereotype management theory to contextualize the educational experiences of 36 high-achieving Black undergraduate women (18–24 years) attending predominantly white institutions. The women discussed how gendered racial stereotypes of Black women's incompetence, excellence, and anger informed their perfectionist tendencies in both adaptive and maladaptive ways. In the adaptive perfectionist excerpts, we found that while women were cognitively aware of the stereotypes placed on Black women, they used this undue pressure as motivational fuel to persist in their short-term academic and long-term occupational goals. Conversely, maladaptive tendencies included procrastination, burnout from a refusal to take breaks, overcommitment to campus responsibilities, preoccupation with doing everything well, and an intense desire to meet others’ expectations even at the expense of their personal health. Overall, the results suggest that Black women's perfectionist tendencies are a byproduct of trying to achieve educational and occupational success within a racist and sexist society and highlight the myriad ways Black women learn to cope with socially prescribed messages and stereotypes.
title: "That bloody [r]!": exploring variation, variability constraints and indexical meanings of non-prevocalic /r/ realisations in L2 English of Polish Migrants in the South of England.
Creators: name: Trebacz, Jan
Publisher: name: University of Reading
Year: 2023

description: One salient feature that has been associated with the L2 English of Polish migrants, the 
largest linguistic minority in the UK (Census, 2011), is the way they pronounce /r/. Szpyra-Kozłowska (2018) and Waniek-Klimczak & Matysiak (2016) suggest the potential social 
function of /r/ in Polish-accented English as a higher-level indexical (Johnstone & Kiesling, 
2008; Labov, 1972; Silverstein, 2003); nonetheless, very little research on variable rhoticity 
and non-prevocalic /r/ realisations had been done in the context of L2 English of Polish 
migrants in the south of England. This study attempted to address this gap by providing 
further evidence for variable rhoticity, investigating /r/ variants employed by these speakers 
and exploring the various factors that impact their choices, focusing on SLA-related, 
phonological and social constraints. Participants’ beliefs regarding indexical meanings linked 
to the variable were also examined. Both quantitative and qualitative data were collected 
from 26 participants. Questionnaires, semi-structured interviews and a sociolinguistic 
interview in English were employed. 6,955 tokens, i.e. words with non-prevocalic /r/, were 
elicited, coded using auditory analysis and visual inspection of spectrogram, analysed in 
SPSS and contextualised using qualitative data.
The results confirm variability in rhoticity and non-prevocalic /r/, the most-frequently 
employed variant being approximants (57% of all tokens), followed by non-rhotic realisations 
(38.7%). Evidence of taps/tap-like variants and idiosyncratic realisations was also found. A 
small percentage of trills was only identified in Word List data. A number of statistically-significant SLA-related and social variables were found, including Formal Instruction in 
English in Poland, Grammatical Range & Accuracy, Self-estimated Level of English and Social 
Grade. Two strongest predictors discouraging non-rhoticity were NORTH and NEAR vowels. 
The presence of style shifts was also identified. In addition, ample evidence for meta-discourse regarding /r/ variants was found. [ɾ] and [r] were found to be frequently linked to 
second-order indexical meanings, signalling alignment with Poland, the notion of 
foreignness, a lack of willingness to integrate into the British society or a specific brand of 
“Polishness” represented by the commonly-reported stereotype of Polish-thug-in-a-track-suit. 
By examining variability in /r/ realisations and its origins, the current study has made a 
contribution to the body of knowledge regarding rhoticity in Polish-accented English as well 
as the wider field of sociophonetics, warranting the need for further investigation of the 
variable in the context of out-group stereotypes and the attached stigma and accent bias.

description: Currently, much software in healthcare is introduced as large-scale suite systems that aim at covering needed functionality for different institutions, wards, and professionals. With these systems, the software is already in place and development is largely replaced with the activity of configuration. Configurable suite systems create new conditions for user participation in healthcare software projects. We want to explore these conditions further, and we ask the following research question: What is the users’ role in the implementation of large healthcare suite systems? In this study, we discuss four ways in which user participation in implementing large-scale suite systems are different from smaller-scale software projects.

For back-to-back $Λd$ pairs a prominent event cluster has been found just below the $m_{^4\textrm{He}}+m_{K^-}-m_{n}$ mass threshold in the $Λd$ invariant mass spectrum of $Λdn$ events, which is evidence for a three-nucleon absorption process of $K^-$ in $^4$He. In addition, an appreciable strength is revealed below $\sim$3220 MeV/$c^2$. Well separated $Σ^0 dn$ events show a peak similar to the case of $Λdn$.

description: In a unifying way, the doorway mechanism explains spectral properties in a rich variety of open mesoscopic quantum systems, ranging from atoms to nuclei. A distinct state and a background of other states couple to each other which sensitively affects the strength function. The recently measured superscars in the barrier billiard provide an ideal model for an in--depth investigation of this mechanism. We introduce two new statistical observables, the full distribution of the maximum coupling coefficient to the doorway and directed spatial correlators. Using Random Matrix Theory and random plane waves, we obtain a consistent understanding of the experimental data.

description: Long-range interacting systems exhibit unusual physical properties not shared by systems with short-range interactions. Understanding the dynamical and statistical effects of long-range interactions yields insights into a host of physical systems in nature and industry. In this work, we investigate the classical microscopic dynamics of screened Coulomb interacting particles confined in the disk, and reveal the featured dynamics and emergent statistical regularities created by the long-range interaction. We highlight the long-range interaction driven fast single-particle and collective dynamics, and the emergent topological defect structure. This work suggests the rich physics arising from the interplay of long-range interaction, topology and dynamics.

description: The article deals with some cultural and methodological reflections developed within a European research project focused on the enhancement of the architectural heritage built in the first half of Twentieth Century. On such a heritage, which has still not been historicised, the community as a whole does not express unanimous judgements of value; at the same time, it is extremely fragile with respect to the aggressive actions linked to the passage of time. In fact, the time of the «short age» acted in different ways, increasing the value of the architectures (with regard to their critical fortune and authorship) but, also, highlighting their intrinsic fragilities and, sometimes, their design and constructive defects. The research just launched aims at defining some criteria, shared at an international level, to identify the most significant buildings/artefacts and the most appropriate methodologies of social inclusion and of technical nature for their conservation and future valorisation. We will do so also taking into account the unforeseeable effects the recent pandemic will have on our lives and cities.

Non-adiabatic transport in a quantum dot turnstile

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We present a theoretical study of the electronic transport through a many-level quantum dot driven by time-dependent signals applied at the contacts to the leads. If the barriers oscillate out of phase the system operates like a turnstile pump under a finite constant bias, as observed in the experiments of Kouwenhoven {\it et al.} [Phys. Rev. Lett. {\bf 67}, 1626 (1991)]. The time-dependent currents and their averages over succesive pumping periods are computed from the Keldysh formalism for tight-binding models. The calculation considers a sudden application of the pumping potentials at $t=0$ which leads to transient features of the time-dependent and averaged currents during the first pumping cycles which turn out to be important in the high-frequency regime. We show that in the transient regime the efficiency of the system as a pump is rather poor because it mainly absorbs charge from both leads in order to fill the levels located below the bias window. Under a finite bias and a low-frequency pumping signal the charge transferred across the system depends on the number of levels located within the bias window. The internal charge dynamics and the role of energy sidebands are investigated. The so called satellite peaks of the averaged current are observed also in the transient regime.

Time-based design for the habitat of the next future

Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2020

description: Today more than ever, our habitats are subject to constant changes and reconfigurations. If the architecture of the twentieth century were devoted to the design of the forms of space, it could be said that architecture of the twenty-first century focuses on designing the forms of time. This is temporal within spatial architecture – that already exists – which through time-based design is re-functionalised, revitalised and re-signified. These scenarios are already underway, as we can verify from the ways we live the spaces using new media. They arise from the simultaneity produced by the coexistence of different realities in the same spaces, but which – on the contrary – also require forms of ubiquity to enter and leave virtual realities and digital worlds. Time-based design creates other hierarchies, compared to the spatial logics that have shaped the buildings we have lived in for millennia, because the possibility of subverting the “consecutive” sequence of spaces means working on the folds of time: a real “habitat”. The materials, therefore, become a new frontier on which time experiments in space. Their increasingly “living” performance is part of the concept of ​​a building, which arises within a temporal and spatial cycle to be reformulated, and which can be computed up to its micro-structure. The theme of time concerns all the scales of the project, from micro materials to the macro dimensions of the city. The latter is redesigned in its new morphologies by means of transport capable of deforming the Cartesian coordinates of space over time, to fold and reshape the planes, and to finally define new proximity and distances.

description: Background: Many Information and Communication Technology (ICT) implementations fail to deliver described effects and organizational goals. Empirical evidence suggests that organizational and socio-technical challenges are frequently overlooked. Objective: The proposed PhD research project aims to develop theoretically informed guidelines and strategies for how clinical managers should be positioned and engaged in ICT implementation, change management and work practice adaptation. Methods: This qualitative study will employ an interpretive approach with data capturing at three different organizational levels: Top management, mid-level clinical management, clinicians. Empiracally we will use the implementation of a structured Electronic Health Record in Norwegian hospitals as case. Conclusion: A better understanding of how ICT portfolios can be governed, and how and too what degree clinical managers should be involved in an accusation and implementation process can improve outcomes and organizational effects of clinical ICT implementations. The proposed research project will study the implementation of large-scale clinical ICT, with the aim of identifying and describing strategies for what role and involvement clinical managers should have in both development, implementation and governance in order to facilitate the needed change management within own organization.

description: The paper presents the results of a research funded by the Veneto Region concerning the study of innovative temporary wooden housing units for the hospitalisation and accommodation of elderly people in the case of functional requalification of buildings used as care homes. The project originates from the observation that existing buildings used as care homes may often need to be redeveloped. In this scenario, a temporary housing unit with advanced comfort and energy saving features may, therefore, constitute an optimal solution for the protection of elderly people and, at the same time, to experiment with new models of living, besides possibly adapting them for permanent accommodation.

The static and dynamic critical exponents are determined for systems starting separately from ordered and disordered initial states. The obtained values of the exponents are in a good agreement with results of the field-theoretic description of the critical behavior of these models in the two-loop approximation and with our results of Monte Carlo simulations of three-dimensional Ising model in equilibrium state.

Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2020

description: The building market offers numerous wood-based products, which are often more performing and suitable for different types of processing, compared to solid wood analogues. Based on the characteristics of this category of products, design tends to seek a durability that is not typical of wood. It, therefore, clashes with traditional practice, which recognises the natural transformation of the material over time and provides for its maintenance and replacement. The restoration of the water pavilion’s wooden parts in the Brion funeral complex provides an opportunity to reflect on the value of time, not only in relation to the material transformation, but also to the construction rationale, through archival research and site investigations.

description: Nonmagnetic and spherically symmetric dielectric material media are investigated in their generality as analogue models, in the domains of geometrical optics, for a few relevant static and spherically symmetric solutions of gravitation, including black holes and wormholes. Typic and desirable gravitational features are systematically linked to the nonlinear properties of the phenomenological dielectric permittivity of the medium. From this, the limitations of such analogies are explored in terms of their corresponding geometric flexibility, dielectric configurations and causal structure.

Measuring and modelling evapotranspiration from Douglas-fir stands
Creators: name: Spittlehouse, David Leslie
Publisher: name: University of British Columbia
Year: 2010

description: Methods of measuring forest evapotranspiration are reviewed and evaluated. Measurements on Douglas-fir stands indicated that eddy correlation, Bowen ratio/energy balance, stomatal diffusion resistance and soil water balance methods agreed with each other to within their respective measurement errors. A detailed error analysis of a Bowen ratio/energy balance system indicated that it could give estimates of evapotranspiration to within ± 15% and ± 40% when evapotranspiration was high and low, respectively. The accuracy of this system was due to the use of a high sensitivity monitoring system, and the periodic reversal of well-matched sensors which results in the cancelling of certain systematic errors. The effects of certain non-cancelling errors are also illustrated. Approaches to modelling forest evapotranspiration are reviewed and two approaches chosen for further study. Data obtained using the Bowen ratio/energy balance, stomatal diffusion resistance and soil water balance methods are used in the development and testing of two forest evapotranspiration models. These models are combined with simple interception and drainage relationships to produce two forest water balance models. [the rest of the abstract can be found in the attached PDF file]

Building on time: the reconstruction of experimental building-yards in France and Italy (1945-55)
Creators: name: Bertolazzi, Angelo

Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2020

description: In the aftermath of WW2, Europe – as the main war scene – endorsed the “fast time” approach to reconstruction. Relying on optimising production-and-building processes, this approach was widely resorted to in experimental quarters, regarded as the “starting point” on which to build the technical know-how leading to the industrialisation of building techniques. This paper analyses the French and Italian experiences. They are closely linked, since in the shared choice of reinforced concrete as the most eligible material, the French experimentation provided a pattern for Italian reconstruction; so, they jointly become trailblazing researches about making building science-based and about organising building-yard work.

In the research project sensor technologies are used to gather large amounts of data to speak on behalf of the ECwD about change in their behaviour. But in order for the data to create value, network-building efforts made by the project researchers is needed, as the case illustrate. Inspired by the framework of partici- patory infrastructuring we illustrate how front-stage as well as back-stage activities leads to negotiations and translations of concerns and data in a process of network-building to- gether with a multiplicity of users and other actors such as ECwD, their loved ones, care- givers, sensors, researchers, municipalities, companies and nursing homes.

description: What is the level of in-permanence present in the idea of temporary emergency solutions? How much do these architectural solutions meet living comfort requirements? How long does an emergency last in Italy? We would like to share some reflections on the environmental quality of temporary housing structures by presenting the research experience carried out in Norcia, in close collaboration with the Municipal Administration. The study analysed the potential for regeneration and reconfiguration of housing modules designed and built to respond to the post-earthquake emergency. This is an optimistic vision of the opportunities offered by the cultural contradictions of living (permanence and change) as an exciting new frontier of the project.

description: Today architectural design is faced with the complex relationship between time and sustainability. In this perspective, the article reports the results of an articulated research activity, which highlights how the need for a temporary location or use of spaces can be achieved with an appropriate level of environmental sustainability, and only through long-term use of resources during the entire life cycle. The concept of “long-lasting temporariness” is outlined, based on the extension of the life of artefacts and on the reuse/recycling of resources at the end of their life, when the reversibility of construction systems, the circularity of materials, and the life cycle management of material and energy flows assume a paradigmatic role.

description: The work of frontline health workers providing access to pregnancy care services to women in South India is highly distributed and often overlooked in the design of healthcare infrastructures. Unlike clinical and nonclinical personnel who engage in different care practices within and across hospital departments with clearly established work roles, the work of frontline workers is performed across different geographical areas beyond the boundaries of the hospital and with loosely defined roles and resources making the coordination of work more complex. Based on a case study investigating the work of frontline health workers, we report a number of material infrastructural arrangements (the Thayi Card, physical and digital registers, and mobile phones) that played a major role supporting community health practices. We conclude by discussing the opportunities that these artefacts offer for the design of healthcareinfrastructures.
The public planning agency and public participation : an organizational approach
Creators: name: Sorensen, Carl Vernon

description: Public planning agencies in democratic political systems are faced by a demand from the public for the opportunity to have an influence on decision-making processes. Evidence suggests that this demand for public participation will not decline. The typical planning agency response to this demand results from common perceptions of the arguments in favour of participation. The literature suggests that this response has been a reluctant and marginal inclusion of public participation in decision-making processes, in reaction to forces external to the agency. The usual arguments for public participation in planning are based in democratic political theory, and are arguments which have to do with the benefits of participation for the public or the political system. These arguments are themselves not conclusive, for there are different schools of democratic theory which ascribe different levels of significance to participation. Public participation approached from the basis of this political theory does not lead to a concept of it being of significant benefit to the planning agency's organizational needs, except insofar as engaging in participation may make the agency conform to political requirements. An alternative approach, based on organizational theory, considers public participation from the viewpoint of how it may serve organizational needs of the public planning agency. The current Open Systems view of organizations provides such a means for undertaking an organizational approach to public participation. It considers an organization's communication with its external environment to be a critical element in its functioning. An examination of the principles and concepts of the Open Systems view of organizations demonstrates that they are applicable to public participation and the public planning agency. The Open Systems view can be integrated with a model of a public planning agency developed according to current planning theory, and with political systems theory as the latter pertains to a planning agency's interrelationships with its environment. When this integration is done within the context of the manner in which the representative democratic system functions, the result suggests that public participation assists in meeting certain "organizational" needs of the public planning agency. This "organizational approach" to public participation provides a rationale for a planning agency's positive attitude towards public participation, since it is an approach which considers the benefits to the planning agency as an organization.
Self-Similar Polytropic Champagne Flows in H II Regions

description: We explore large-scale hydrodynamics of H II regions for various self-similar shock flows of a polytropic gas cloud under self-gravity and with quasi-spherical symmetry. We formulate cloud dynamics by invoking specific entropy conservation along streamlines and obtain global self-similar "champagne flows" for a conventional polytropic gas with shocks as a subclass. Molecular cloud cores are ionized and heated to high temperatures after the onset of nuclear burning of a central protostar. We model subsequent evolutionary processes in several ways and construct possible self-similar shock flow solutions. We may neglect the mass and gravity of the central protostar. The ionization and heating of the surrounding medium drive outflows in the inner cloud core and a shock travels outwards, leading to the so-called "champagne phase" with an expanding outer cloud envelope. Complementarily, we also consider the expansion of a central cavity around the centre. As the inner cloud expands plausibly due to powerful stellar winds, a cavity (i.e., `void' or `bubble') can be created around the centre, and when the cavity becomes sufficiently large, one may neglect the gravity of the central protostar. We thus present self-similar shock solutions for "champagne flows" with an expanding central void. We compare our solutions with isothermal solutions and find that the generalization to the polytropic regime brings about significant differences of the gas dynamics, especially for cases of n<1, where n is a key scaling index in the self-similar transformation. We also compare our global polytropic self-similar solutions with numerical simulations on the expansion of H II regions.

Mixed reality navigation of a systemic venous baffle obstruction: unravelling the percutaneous approach in atrial switch operation. Eur Heart J. 2020 Nov 27:ehaa961. doi: 10.1093/eurheartj/ehaa961. Epub ahead of print. PMID: 33246335. Congenital heart diseases in adulthood (ACHD) are an increasing evidence, hence the need of interventional procedures due to late-onset complications of early-life corrective surgery. Systemic venous baffle (SVB) obstruction occurs in up to 10% of transposition of great arteries after atrial switch operation (TGA-ASO, Supplementary material online, Movie S1) and stenting is the first-line recommended treatment. However, SVB arrangement with the pulmonary systemic baffle remains challenging to interpret, representing a possible limitation for transcatheter approach. Herein, we exploited a novel image-based platform to set up the percutaneous relief of a superior vena cava (SVC) pathway obstruction in TGA-ASO. Three-dimensional (3D) pre-catheterization anatomy (Panel A) was investigated employing a holographic augmented reality prototype (Panel A1, ARTINESS, Milan, Italy) to directly inspect the 3D anatomy (Panel A2) and perceive the severity of SVB stenosis and its longitudinal extension (Panel A3; Supplementary material online, Movie S2). Multi-planar analysis of SVC cross-sections (Panel B1) effectively supported the stent sizing. A 48-mm ANDRA stent (Andramed, Reutlingen, Germany) was deployed on the stenotic baffle and post-dilated with a balloon-in-balloon catheter 18 × 50 mm (BiB® Catheter, NUMED, Hopkinton, NY, USA; Supplementary material online, Movie S3); peak-to-peak SVC gradient reverted from 6 mmHg to a baseline value. Post-catheterization 3D computer tomography scan reconstruction was navigated through mixed reality, pinpointing the results of the procedure (Panel B2, Supplementary material online, Movie S4).

description: Nowadays, professional caregivers need to provide care in less and less time, while quality requirements are increasing. Therefore, access to information and guidance need to be improved. One solution to support caregivers is the Care Lenses which support caregivers during everyday care with Augmented Reality (AR). AR may provide additional information, guidance and remote support. While technology is not always the best solution for such a difficult and manifold problem, extensive evaluations are needed in order to investigate the potential of AR in everyday care context. In this Paper we summarize perceptions of 25 caregivers, who were participating in our study, using Care Lenses in a simulated everyday care situation. It shows AR is able to support caregiver during their work and what kind of problems might occur during the introduction into professional care.
