description: Chronic diseases are a global burden affecting billions of people, causing millions of deaths per year and excessive costs for healthcare systems. Smart and ubiquitous eHealth applications supporting patients in their everyday life could have a major impact on patients’ quality of life and treatment outcomes. In this paper, we present results of an online survey with 320 participants (188 chronically ill patients, 132 persons related to chronic diseases in various ways, e.g. relatives) in order to gain insights into expectations and concerns of patients with chronic conditions towards eHealth solutions based on Internet of Things (IoT) technologies. 175 of them finished the questionnaire completely. In addition, interviews with 8 physicians on patient-doctor-relationships, therapy processes of patients with chronic health conditions and opportunities for improvements through IoT-based eHealth services were conducted. By thematic analysis of the results, requirements were identified that future applications need to fulfill to achieve acceptance and long term usage. Accordingly, we present six design principles for IoT based eHealth applications for chronically ill patients.

Comparison of the Phenomena of Light Refraction and Gravitational Bending

description: The properties of light in the presence of electromagnetic and gravitational fields are compared. Once one takes account of the fact that clock rates vary with distance from a massive object, it is argued that in an absolute sense light frequencies remain constant in both interactions. It is also pointed out that the criterion used by Einstein for the angle of curvature of light rays passing close to the sun is not their actual trajectory but rather Huygens' Principle. The latter only requires that the speed of light vary with distance from a gravitational source in order to produce a measurable effect. As a result, the observed displacement of star images during solar eclipses can be explained on the basis of a rotation of the wave front of light without assuming that individual photons are actually deflected by the sun. A calculation reported by Schiff in 1960 based on the assumption that light travels in a straight line for all local observers obtains the same closed expression for the angle of displacement of star images as in Einstein's original work, in support of this interpretation. Since light is believed to follow a straight-line trajectory within any given homogeneous transparent medium, it is argued that light refraction and gravitational bending have more in common than is generally realized.

Spanish-speaking Latin Americans in Canadian workplaces

description: The linguistic landscape of Canadian workplaces is becoming more diverse as organizations employ individuals who come from various countries and speak different native languages. As language is an important marker of identity and group membership, language-based identities are powerful in shaping workplace experiences. Guided by both the ethnolinguistic identity theory (ELIT: Giles et al., 1977; Giles & Johnson, 1987) and communication accommodation theory (CAT: e.g., Dragojevic et al., 2016; Gallois et al., 2005; Giles & Ogay, 2006), this study explores the experiences of Spanish-speaking Latin Americans working in the Canadian National Capital Region in relation to their linguistic identities, coping strategies, and intergroup interactions. A thematic analysis of 24 semi-structured interviews shows that participants experience a dynamic shift in their identity in which they move between feelings of self-doubt and a sense of confidence and comfort in their workplaces. This shift occurs as they navigate the cognitive and emotional experiences of working in a nonnative language. Factors that influence this identity shift include social comparisons, positive implications associated with their native linguistic identity, negative evaluations, and empathy in the workplace. This study also provides a detailed description of the intrapersonal, interpersonal, and interactional coping strategies that participants enact to navigate their workplaces. In terms of intergroup interactions, the participant’s experiences, their evaluations, and reactions to accommodative or nonaccommodative behaviours from native speaking peers in their workplaces are explored. The final pages of this study include some recommendations for human resource practitioners.

description: Quantum machine learning (QML) algorithms have obtained great relevance in the machine learning (ML) field due to the promise of quantum speedups when performing basic linear algebra subroutines (BLAS), a fundamental element in most ML algorithms. By making use of BLAS operations, we propose, implement and analyze a quantum k-means (qk-means) algorithm with a low time complexity of $\mathcal{O}(NKlog(D)I/C)$ to apply it to the fundamental problem of discriminating quantum states at readout. Discriminating quantum states allows the identification of quantum states $|0\rangle$ and $|1\rangle$ from low-level in-phase and quadrature signal (IQ) data, and can be done using custom ML models. In order to reduce dependency on a classical computer, we use the qk-means to perform state discrimination on the IBMQ Bogota device and managed to find assignment fidelities of up to 98.7% that were only marginally lower than that of the k-means algorithm. Inspection of assignment fidelity scores resulting from applying both algorithms to a combination of quantum states showed concordance to our correlation analysis using Pearson Correlation coefficients, where evidence shows cross-talk in the (1, 2) and (2, 3) neighboring qubit couples for the analyzed device.
Sharp Stability Estimates for the Force-based Quasicontinuum Method

description: A sharp stability analysis of atomistic-to-continuum coupling methods is essential for evaluating their capabilities for predicting the formation and motion of lattice defects. We formulate a simple one-dimensional model problem and give a detailed analysis of the stability of the force-based quasicontinuum (QCF) method. The focus of the analysis is the question whether the QCF method is able to predict a critical load at which fracture occurs. Numerical experiments show that the spectrum of a linearized QCF operator is identical to the spectrum of a linearized energy-based quasi-nonlocal quasicontinuum operator (QNL), which we know from our previous analyses to be positive below the critical load. However, the QCF operator is non-normal and it turns out that it is not generally positive definite, even when all of its eigenvalues are positive. Using a combination of rigorous analysis and numerical experiments, we investigate in detail for which choices of "function spaces" the QCF operator is stable, uniformly in the size of the atomistic system. Force-based multi-physics coupling methods are popular techniques to circumvent the difficulties faced in formulating consistent energy-based coupling pproaches. Even though the QCF method is possibly the simplest coupling method of this kind, we anticipate that many of our observations apply more generally.

description: We investigate the geometric interpretation of quantized Nambu-Poisson structures in terms of noncommutative geometries. We describe an extension of the usual axioms of quantization in which classical Nambu-Poisson structures are translated to n-Lie algebras at quantum level. We demonstrate that this generalized procedure matches an extension of Berezin-Toeplitz quantization yielding quantized spheres, hyperboloids, and superspheres. The extended Berezin quantization of spheres is closely related to a deformation quantization of n-Lie algebras, as well as the approach based on harmonic analysis. We find an interpretation of Nambu-Heisenberg n-Lie algebras in terms of foliations of R^n by fuzzy spheres, fuzzy hyperboloids, and noncommutative hyperplanes. Some applications to the quantum geometry of branes in M-theory are also briefly discussed.

description: We present a new variational method to study the dynamics of a closed bosonic many-body system, the time-dependent hypernetted-chain Euler-Lagrange method, tHNC . Based on the Jastrow ansatz, it accounts for quantum fluctuations in a non-perturbative way. tHNC scales well with the number of dimensions, as demonstrated by our results on one, two, and three dimensions. We apply the tHNC method to interaction quenches, i.e. sudden changes of the interaction strength, in homogeneous Bose gases. When the quench is strong enough that the final state has roton excitations (as found and predicted for dipolar and Rydberg-dressed Bose-Einstein condensates, respectively), the pair distribution function exhibits stable oscillations. For validation, we compare tHNC results with time-dependent variational Monte Carlo results in one and two dimensions.

description: This paper presents the design, implementation, and evaluation of a system that supports the analysis of visitor interactions with augmented reality (AR) content in museum exhibitions. It can be used in conjunction with the AR authoring and presentation system InfoGrid. InfoGrid enables museum professionals to setup indoor and outdoor AR tours by connecting visual features of physical exhibits with different kinds of media. Visitors can retrieve these media by using the InfoGrid mobile app and scanning the target areas. The analytics application presented in this paper aims to help museum professionals to get an understanding of how visitors are using the AR tours they created. It shows how visitors interact with each AR element and reveals if some elements have been unrecognized. It allows museum professionals to visually inspect the data mapped onto a digital floor plan of the museum. The system visualizes movement paths on the floor plan as well as heatmaps that represent the overall time spent in an exhibit. Data for the evaluation system is anonymously generated by using a logging mechanism of the InfoGrid AR mobile app. Finally, we present a usability evaluation of the analytics system, discuss the results as well as future work.

Zum 1.1.2020 wurden die Alten-, Kranken- und Kinderkrankenpflegeausbildungen zur generalistischen Pflegeausbildung zusammengefasst. Der Digitalisierungsschub erfordert, die Vermittlung digitaler Medienkompetenzen stärker in die Pflegeausbildung und -didaktik zu integrieren. [1] Die COVID-19-Krise erhöht Druck und Chance, digitale Lehrangebote zu schaffen. [2] Das hier vorgestellte Projekt „DAPF 4.0 – Digitale Akademie Pflege 4.0“ hat zum Ziel, Lehrpersonal zu befähigen, digitale Lehr- und Lernszenarien zu erstellen und so individualisiertes Lernen und Medienkompetenzaufbau angesichts zukünftiger Anforderungen zu ermöglichen. [3] Eine offene digitale Transfer-Plattform führt die Er-gebnisse zu einem „Baukasten zum Mitnehmen“ zusammen. In den partizipativen Prozess der Technikentwicklung wird die Heterogenität von Lernenden (z.B. hinsichtlich Bildung, Alter, Geschlecht) und Lehrenden (z.B. hinsichtlich digitaler Kom-petenzen) dieser „Community of Practice“ [4] einbezogen, da diese in der generalistischen Pflegeausbildung zunimmt.

description: In digitalen Medien wie dem Internet ist der Inhalt entscheidend. Die subjektive Wahrnehmung von Inhalten durch die Nutzer*innen beeinflusst eine Vielzahl ihrer Bewertungen und Einstellungen und hat Konsequenzen für das Verhalten. Daher ist es essentiell die Inhaltswahrnehmungen der Nutzer*innen zu messen. Eine solche Erfassung sollte möglichst valide sein, muss aber gleichzeitig oft möglichst kurz sein. Hierfür haben wir eine vier Items umfassende Kurzversion des Web-CLIC-Fragebogens [18] erstellt. Dieser Web-CLIC-S wurde in einer Reihe von drei Studien getestet, in Summe n = 1.414 Befragte bewerteten dabei insgesamt 33 voll funktionsfähige Websites verschiedener Inhaltsbereiche. Der Web-CLIC-S spiegelt einen g-Faktor der subjektiven Wahrnehmung von Webinhalten wider: Die Unidimensionalität wurde mittels konfirmatorischer Faktoranalyse geprüft. Der Web-CLIC-S weist hohe interne Konsistenz und eine hohe kurz- bis mittelfristige Retest-Reliabilität auf. Darüber hinaus finden wir starke Evidenz für die Konstruktvalidität im Sinne von konvergenter, divergenter, diskriminativer, konkurrenter, inkrementeller und prädiktiver Validität. Interpretationshilfen in Form von Benchmarks für 12 verschiedene Inhaltsbereiche und optimale Schwellenwerte wurden auf Basis von 12.568 Bewertungen für insgesamt 183 verschiedene Websites berechnet. Insgesamt zeigen die vorliegenden Studien, dass der Web-CLIC-S als fundiertes Screening-Instrument zur Beurteilung der subjektiven Wahrnehmung von Inhalten durch die User in Praxis und Forschung dienen kann.
Effective Field calculations of the Energy Spectrum of the $\mathcal{PT}% $-Symmetric ($-x^{4}$) Potential

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this work, we show that the traditional effective field approach can be applied to the $\mathcal{PT}$-symmetric wrong sign ($-x^{4}$) quartic potential. The importance of this work lies in the possibility of its extension to the more important $\mathcal{PT}$-symmetric quantum field theory while the other approaches which use complex contours are not willing to be applicable. We calculated the effective potential of the massless $-x^{4}$ theory as well as the full spectrum of the theory. Although the calculations are carried out up to first order in the coupling, the predicted spectrum is very close to the exact one taken from other works. The most important result of this work is that the effective potential obtained, which is equivalent to the Gaussian effective potential, is bounded from below while the classical potential is bounded from above. This explains the stability of the vacuum of the theory. The obtained quasi-particle Hamiltonian is non-Hermitian but $\mathcal{PT}$-symmetric and we showed that the calculation of the metric operator can go perturbatively. In fact, the calculation of the metric operator can be done even for higher dimensions (quantum field theory) which, up till now, can not be calculated in the other approaches either perturbatively or in a closed form due to the possible appearance of field radicals. Moreover, we argued that the effective theory is perturbative for the whole range of the coupling constant and the perturbation series is expected to converge rapidly (the effective coupling $g_{eff}={1/6}$).

description: A frustrated Ising model on a diamond hierarchical lattice is studied. We obtain the exact partition function of this model and calculate the transition temperature, specific heat, entropy, magnetization, and ferromagnetic correlation function. Depending on the magnitude of a parameter giving the frustration, there exist three types of ground states: ferromagnetic, classical spin-liquid with highly developed short-range order, and paramagnetic. The dependence of the zero-temperature entropy on the frustration parameter has an infinite number of steps. The temperature dependence of the specific heat exhibits many peaks with decreasing temperature and entropy loss. The dominant spin configurations at low temperatures are also specified.

description: Hexagonal boron nitride (hBN) is a van der Waals semiconductor with a wide bandgap of ~ 5.96 eV. Despite the indirect bandgap characteristics of hBN, charge carriers excited by high energy electrons or photons efficiently emit luminescence at deep-ultraviolet (DUV) frequencies via strong electron-phonon interaction, suggesting potential DUV light emitting device applications. However, electroluminescence from hBN has not been demonstrated at DUV frequencies so far. In this study, we report DUV electroluminescence and photocurrent generation in graphene/hBN/graphene heterostructures at room temperature. Tunneling carrier injection from graphene electrodes into the band edges of hBN enables prominent electroluminescence at DUV frequencies. On the other hand, under DUV laser illumination and external bias voltage, graphene electrodes efficiently collect photo-excited carriers in hBN, which generates high photocurrent. Laser excitation micro-spectroscopy shows that the radiative recombination and photocarrier excitation processes in the heterostructures mainly originate from the pristine structure and the stacking faults in hBN. Our work provides a pathway toward efficient DUV light emitting and detection devices based on hBN.

Transition states in protein folding

Publisher: name: arXiv
Year: 2009
Subjects: subject: Biomolecules (q-bio.BM)
subject: FOS: Biological sciences

description: The folding dynamics of small single-domain proteins is a current focus of simulations and experiments. Many of these proteins are 'two-state folders', i.e. proteins that fold rather directly from the denatured state to the native state, without populating metastable intermediate states. A central question is how to characterize the instable, partially folded conformations of two-state proteins, in particular the rate-limiting transition-state conformations between the denatured and the native state. These partially folded conformations are short-lived and cannot be observed directly in experiments. However, experimental data from detailed mutational analyses of the folding dynamics provide indirect access to transition states. The interpretation of these data, in particular the reconstruction of transition-state conformations, requires simulation and modeling. The traditional interpretation of the mutational data aims to reconstruct the degree of structure formation of individual residues in the transition state, while a novel interpretation aims at degrees of structure formation of cooperative substructures such as alpha-helices and beta-hairpins. By splitting up mutation-induced free energy changes into secondary and tertiary structural components, the novel interpretation resolves some of the inconsistencies of the traditional interpretation.

We designed and developed the Cost-Benefit Tracker as a simple software-based BPMN 2.01 tool by integrating the concepts of the Service-Dominant Business Model design. As a result, the software is simple and straightforward to use more than enterprise BPMN 2.0 software. The entrepreneurs can use the presented softwaresupported method to financially evaluate own business processes designed as BPMN 2.0 diagrams, before committing a large amount of financial resources into realisation of these. In order to evaluate the usefulness and usability of the proposed software we tested it with a specific scenario including tasks with representative test persons from possible target groups. We also used standardized surveys like Computer System Usability Questionnaire (CSUQ) and Nielsen’s Heuristic model (NHE) to obtain the insights on usability of the system. The findings of usability evaluation of CB Tracker will be presented as main contribution of this paper.

description: In the framework of the so called link approach we study exact lattice supersymmetry for the simplest supersymmetric model: N=1 supersymmetry in D=1. The model is described by a lattice with spacing a/2, thus containing twice as many sites as the conventional one. The boson and fermion are related through a 2pi/a momentum shift, which can provide an interpretation of them being species doublers to each other. An exactly supersymmetric lattice action can be written within this scheme in momentum representation, which however turns out to be non local in coordinate space.

description: Betrachtet man Landwirtschaft unter dem Blickwinkel kritischer Infrastruktur, da sie einen essenziellen Bestandteil der lebenswich-tigen Nahrungsmittelproduktion darstellt, so wird schnell klar, dass auch die dort eingesetzten Werkzeuge hohen Anforderungen stand-halten müssen. Mit dem Einsatz moderner digitaler Werkzeuge werden Erwartungen verbunden, sowohl den gesellschaftlichen Anforderungen nach Qualität und Quantität von Nahrungsmitteln gerecht zu werden, als auch dabei die Produktion möglichst effi-zient unter Berücksichtigung von Umwelt und Natur durchzufüh-ren. Ebenso gilt es die Interessen der landwirtschaftlich Beschäftig-ten zu wahren. Die Geobox-Infrastruktur verfolgt dieses Ziel. Zu den wichtigsten Aspekten, die dabei erfüllt werden müssen, zählen eine resiliente Systemarchitektur, Sicherheit und Datenhoheit, aber auch Gebrauchstauglichkeit. Dieser Beitrag diskutiert den For-schungsansatz sowie zentrale Anforderungen.

description: Privacy Assistants (PAs) are a promising method to support users in making and communicating privacy-related decisions. In this work in progress paper, we present a study design to investigate users perspective on PAs in the context of mobile apps in an explorative user-centric workshop. The participants are asked to provide 1) which information they are comfortable sharing with their PA, 2) how the PA learns this information, 3) how the PA should assist and how it should communicate with the participants, and 4) which entity should provide the PA. Participants are encouraged to think aloud during the workshop and are interviewed as debriefing. The initial results of a pilot study indicate that there may be a great variety of requirements and ideas of a PA between users.
Quantifying Non-Stationarity with Information Theory

description: We introduce an index based on information theory to quantify the stationarity of a stochastic process.The index compares on the one hand the information contained in the increment at the time scale $τ$ of the process at time $t$ with, on the other hand, the extra information in the variable at time $t$ that is not present at time $t-τ$. By varying the scale $τ$, the index can explore a full range of scales. We thus obtain a multi-scale quantity that is not restricted to the first two moments of the density distribution, nor to the covariance, but that probes the complete dependences in the process. This index indeed provides a measure of the regularity of the process at a given scale.Not only is this index able to indicate whether a realization of the process is stationary, but its evolution across scales also indicates how rough and non-stationary it is.We show how the index behaves for various synthetic processes proposed to model fluid turbulence, as well as on experimental fluid turbulence measurements.

description: We discuss practical and theoretical solutions to problems that arose during the development of a collaborative VR application in which a teacher guides students through visualization and interactive interpretation of a geological dataset. To provide access to a large number of tools, we introduced a dashboard-style menu that rotates and moves to follow the user through the environment. We expect users to need good awareness of each other in the virtual environment, and especially to understand each other’s attention to specific terrain surface features or annotations. For this, we display an eye gaze cue on the visualized terrain and visually tether a nametag widget on the dashboard to each user’s avatar. Results of an initial usability review, involving an expert geologist guiding students, show promise for sharing eye gaze with a gaze trail as a basic method for understanding attention. Other tested indicators of avatar location or view appeared less important during the terrain feature presentation and interpretation.We additionally summarize ongoing work to enhance collaborative awareness through other eye tracking metrics and physiological data.

description: Der demografische Wandel und die digitale Transformation stellen unsere heutige Gesellschaft vor große Herausforderungen. Durch die zunehmende Überalterung leben immer mehr Menschen in Wohnungen, die nicht altersgerecht ausgelegt sind. Gleichzeitig können Senioren ohne Hinführung nur schwer mit den technischen Möglichkeiten umgehen, die die digitale Transformation bietet, indem sie bspw. ein einfacheres Leben in den eigenen vier Wänden ermöglicht. Wir berichten von der Problemstellung in einem Projekt rund um die Digitalisierung einer kommunalen Wohnberatungsstelle. Hierbei ist sowohl die digitale Inklusion der zumeist älteren ehrenamtlichen Wohnberater als auch die Vermittlung von Digitalkompetenzen bei den zu beratenden Senioren eine große Herausforderung.

description: Computer unterstützen Menschen heute zunehmend in sicherheitskritischen Kontexten und Notfallsituationen: Beispielsweise in der Medizin und Produktion, aber auch im Verkehr und Katastrophenschutz begegnen wir immer häufiger digitalen Systemen, mit denen wir interagieren. Vor allem mobile Anwendungen haben im Laufe der letzten Jahre immer mehr an Relevanz gewonnen. Aufgrund vielfältiger Einsatzmöglichkeiten müssen hier diverse Disziplinen zusammenwirken, um die Kooperation zwischen Menschen und Maschinen sicher und effizient zu gestalten. Doch auch die Zusammenarbeit zwischen Menschen wird zunehmend technologisch unterstützt, was sich u.a. in der steigenden Popularität sozialer Medien widerspiegelt. Mithilfe solcher Systeme kann eine Kommunikation, Awareness und Koordination insbesondere in der Krisenbewältigung angestrebt und erreicht werden, sie bringen aufgrund ihrer teilweise technischen Komplexität aber auch Probleme mit sich. Im Zentrum dieses Workshops stehen Erkenntnisse zur Mensch-Computer-Interaktion in sicherheitskritischen Anwendungsgebieten.

description: In Bioinformatics, text mining and text data mining sometimes interchangeably used is a process to derive high-quality information from text. Perl Status Reporter (SRr) is a data fetching tool from a flat text file and in this research paper we illustrate the use of SRr in text or data mining. SRr needs a flat text input file where the mining process to be performed. SRr reads input file and derives the high quality information from it. Typically text mining tasks are text categorization, text clustering, concept and entity extraction, and document summarization. SRr can be utilized for any of these tasks with little or none customizing efforts. In our implementation we perform text categorization mining operation on input file. The input file has two parameters of interest (firstKey and secondKey). The composition of these two parameters describes the uniqueness of entries in that file in the similar manner as done by composite key in database. SRr reads the input file line by line and extracts the parameters of interest and form a composite key by joining them together. It subsequently generates an output file consisting of the name as firstKey secondKey. SRr reads the input file and tracks the composite key. It further stores all that data lines, having the same composite key, in output file generated by SRr based on that composite key.
