Subjects: Applied Computer Science

description: This paper briefly presents two concepts of “RE” (1) re-empowering individuals using personal mobile technology reconstructed as measurement instruments and (2) re-cycle as a design constraint for extending a product’s usable lifetime. In the first example we demonstrate the integration of simple low-cost, low-power air quality sensors attached to a mobile phone. In the re-cycle case, we demonstrate the extended re-use of mobile phones using them as toolkits for new duties.

description: It is a great honour for me to write these few lines of preface to the special issues of Substantia dedicated to the 150th anniversary of the Periodic Table by Dmitrij Mendeleev. In 2019 there are other important anniversaries besides that of the periodic table. One of these is the centenary of Primo Levi’s birth. I believe these two anniversaries are strictly related, in fact the Periodic Table by Levi has been considered by the Royal Institution of Great Britain as the “best book of science ever written”.

The Cognitive Tutor Authoring Tools (CTAT) provide both. Using CTAT, real-world ”Example-Tracing Tutors” can be created without programming. CTAT also provides various kinds of support for controlled experiments, such as administration of different experimental treatments, logging, and data analysis. We present two case studies in which Example-Tracing Tutors created with CTAT were used in classroom experiments. The case studies illustrate a number of new features in CTAT: Use of Macromedia Flash MX 2004 for creating tutor interfaces, extensions to the Example-Tracing Engine that allow for more flexible tutors, a Mass Production facility for more efficient template-based authoring, and support for controlled experiments.

description: Measuring dependence in a multivariate time series is tantamount to modelling its dynamic structure in space and time. In the context of a multivariate normally distributed time series, the evolution of the covariance (or correlation) matrix over time describes this dynamic. A wide variety of applications, though, requires a modelling framework different from the multivariate normal. In risk management the non-normal behaviour of most financial time series calls for non-Gaussian dependence. The correct modelling of non-Gaussian dependences is therefore a key issue in the analysis of multivariate time series. In this paper we use copulae functions with adaptively estimated time varying parameters for modelling the distribution of returns, free from the usual normality assumptions. Further, we apply copulae to estimation of Value-at-Risk (VaR) of portfolios and show their better performance over the RiskMetrics approach, a widely used methodology for VaR estimation.

description: We analyze strong field atomic dynamics semiclassically, based on a full time-dependent description with the Hermann-Kluk propagator. From the properties of the exact classical trajectories, in particular the accumulation of action in time, the prominent features of above threshold ionization (ATI) and higher harmonic generation (HHG) are proven to be interference phenomena. They are reproduced quantitatively in the semiclassical approximation. Moreover, the behavior of the action of the classical trajectories supports the so called strong field approximation which has been devised and postulated for strong field dynamics.

description: and compelling applications, but raises very real privacy risks. Existing approaches to privacy generally treat people as the entity of interest, often using a fidelity tradeoff to manage the costs and benefits of revealing a person’s location. However, these approaches cannot be applied in some applications, as a reduction in precision can render location information useless. This is true of a category of applications that use location data collected from multiple people to infer such information as whether there is a traffic jam on a bridge, whether there are seats available in a nearby coffee shop, when the next bus will arrive, or if a particular conference room is currently empty. We present hitchhiking, a new approach that treats locations as the primary entity of interest. Hitchhiking removes the fidelity tradeoff by preserving the anonymity of reports without reducing the precision of location disclosures. We can therefore support the full functionality of an interesting class of location-based applications without introducing the privacy concerns that would otherwise arise.
BV solutions and viscosity approximations of rate-independent systems

description: In the nonconvex case solutions of rate-independent systems may develop jumps as a function of time. To model such jumps, we adopt the philosophy that rate independence should be considered as limit of systems with smaller and smaller viscosity. For the finite-dimensional case we study the vanishing-viscosity limit of doubly nonlinear equations given in terms of a differentiable energy functional and a dissipation potential which is a viscous regularization of a given rate-independent dissipation potential. The resulting definition of `BV solutions' involves, in a nontrivial way, both the rate-independent and the viscous dissipation potential, which play a crucial role in the description of the associated jump trajectories. We shall prove a general convergence result for the time-continuous and for the time-discretized viscous approximations and establish various properties of the limiting $BV$ solutions. In particular, we shall provide a careful description of the jumps and compare the new notion of solutions with the related concepts of energetic and local solutions to rate-independent systems.

description: Four IRAS-detected early type galaxies were observed with ISO. With the exception of the 15 micron image of NGC1052, the mid-IR emission from NGC1052, NGC1155, NGC5866 and NGC6958 at 4.5, 7 and 15 microns show extended emission. Mid-IR emission from NGC1052, NGC1155, and NGC6958 follows a de Vaucouleurs profile. The ratio of 15/7 micron flux decreases with radius in these galaxies, approaching the values empirically observed for purely stellar systems. In NGC5866, the 7 and 15 micron emission is concentrated in the edge-on dust lane. All the galaxies are detected in the [CII] line, and the S0s NGC1155 and NGC5866 are detected in the [OI] line as well. The ISO-LWS observations of the [CII] line are more sensitive measures of cool, neutral ISM than HI and CO by about a factor of 10-100. Three of four early type galaxies, namely NGC1052, NGC6958 and NGC5866, have low ratio FIR/Blue and show a lower [CII]/FIR, which is due to a softer radiation field from old stellar populations. The low [CII]/CO ratio in NGC5866 ([CII]/CO(1-0) < 570) confirms this scenario. We estimate the UV radiation expected from the old stellar populations in these galaxies and compare it to that needed to heat the gas to account for the cooling observed [CII] and [OI] lines. In three out of four galaxies, NGC1052, NGC5866 and NGC6958, the predicted UV radiation falls short by a factor of 2-3. In view of the observed intrinsic scatter in the "UV-upturn" in elliptical galaxies and its great sensitivity to age and metallicity effects, this is not significant. However, the much larger difference (about a factor of 20) between the UV radiation from old stars and that needed to produce the FIR lines for NGC 1155 is strong evidence for the presence of young stars, in NGC1155.

description: The transformer architecture with its attention mechanism is the state-of-the-art deep learning method for sequence learning tasks and has achieved superior results in many areas such as NLP. Utilizing the transformer architecture for the prediction of sequential time series such as financial time series has hardly been investigated in previous studies. In this research paper, the transformer architecture with time embeddings is used in foreign exchange (FX) trading, the world’s largest financial market, and tests its suitability. A systematic comparison is made between transformer and benchmark models. It also examined which influence multivariate, cross-sectional input data have on the forecasting performance of the various models. The goal of the paper is to contribute to the empirical literature on FX forecasting by introducing a transformer with time embeddings to the forecasting community and assessing the accuracy of corresponding models by forecasting exchange rate movements. Empirical results indicate the suitability of transformer models for FX-Spot forecasting in general but also evidence the need for transformer models for multivariate, cross-sectional input data to outperform other state-of-the-art neural networks such as LSTM.

description: We investigate the scattering phenomena in two dimensions produced by a general finite-range nonseparable potential. This situation can appear either in a Cartesian geometry or in a heterostructure with cylindrical symmetry. Increasing the dimensionality of the scattering problem new processes as the scattering between conducting channels and the scattering from conducting to evanescent channels are allowed. For certain values of the energy, called resonance energy, the transmission through the scattering region changes dramatically in comparison with an one-dimensional problem. If the potential has an attractive character even the evanescent channels can be seen as dips of the total transmission. The multi-channel current scattering matrix is determined using its representation in terms of the R-matrix. The resonant transmission peaks are characterized quantitatively through the poles of the current scattering matrix. Detailed maps of the localization probability density sustain the physical interpretation of the resonances. Our formalism is applied to a quantum dot in a two dimensional electron gas and a conical quantum dot embedded inside a nanowire.

description: We address the issue of large-order expansions in strong-field QED. Our approach is based on the one-loop effective action encoded in the associated photon polarisation tensor. We concentrate on the simple case of crossed fields aiming at possible applications of high-power lasers to measure vacuum birefringence. A simple next-to-leading order derivative expansion reveals that the indices of refraction increase with frequency. This signals normal dispersion in the small-frequency regime where the derivative expansion makes sense. To gain information beyond that regime we determine the factorial growth of the derivative expansion coefficients evaluating the first 80 orders by means of computer algebra. From this we can infer a nonperturbative imaginary part for the indices of refraction indicating absorption (pair production) as soon as energy and intensity become (super)critical. These results compare favourably with an analytic evaluation of the polarisation tensor asymptotics. Kramers-Kronig relations finally allow for a nonperturbative definition of the real parts as well and show that absorption goes hand in hand with anomalous dispersion for sufficiently large frequencies and fields.

description: In this paper we consider the optimal stopping problem for general dynamic monetary utility functionals. Sufficient conditions for the Bellman principle and the existence of optimal stopping times are provided. Particular attention is payed to representations which allow for a numerical treatment in real situations. To this aim, generalizations of standard evaluation methods like policy iteration, dual and consumption based approaches are developed in the context of general dynamic monetary utility functionals. As a result, it turns out that the possibility of a particular generalization depends on specific properties of the utility functional under consideration.

description: This paper yields a two-scale homogenization result for a rate-independent elastoplastic system. The presented model is a generalization of the classical model of linearized elastoplacticity with hardening, which is extended by a gradient term of the plastic variables. The associated stored elastic energy density has periodically oscillating coefficients, where the period is scaled by ε > 0 . The additional gradient term of the plastic variables z is contained in the elastic energy with a prefactor εγ (γ ≥ 0) . We derive different limiting models for ε → 0 in dependence of &gamma ;. For γ > 1 the limiting model is the two-scale model derived in [MielkeTimofte07], where no gradient term was present. For γ = 1 the gradient term of the plastic variable survives on the microscopic cell poblem, while for γ ∈ [0,1) the limit model is defined in terms of a plastic variable without microscopic fluctuation. The latter model can be simplified to a purely macroscopic elastoplasticity model by homogenisation of the elastic part.

description: We present a novel method for analyzing Small Angle X-ray Scattering data on multilamellar phospholipid bilayer systems at full hydration. The method utilizes a modified Caille' theory structure factor in combination with a Gaussian model representation of the electron density profile such that it accounts also for the diffuse scattering between Bragg peaks. Thus, the method can retrieve structural information even if only a few orders of diffraction are observed. We further introduce a new procedure to derive fundamental parameters, such as area per lipid, membrane thickness, and number of water molecules per lipid, directly from the electron density profile without the need of additional volumetric measurements. The theoretical apparatus is applied to experimental data on 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine and 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine liposome preparations.

description: Numerous studies have explored influencing factors in COVID-19, yet empirical evidence on spatiotemporal dynamics of COVID-19 inequalities concerning both socioeconomic and environmental factors at an intra-urban scale is lacking. This study, therefore, focuses on neighborhood-level spatial inequalities of the COVID-19 incidences in relation to socioeconomic and environmental factors for Berlin-Neukölln, Germany, covering six pandemic periods (March 2020 to December 2021). Spatial Bayesian negative binomial mixed-effect models were employed to identify influencing factors and risk patterns for different periods. We identified that (1) influencing factors and relative risks varied across time and space, with sociodemographic factors exerting a stronger influence over environmental features; (2) as the most identified predictors, the population with migrant backgrounds was positively associated, and the population over 65 was negatively associated with COVID-19 incidence; (3) certain neighborhoods consistently faced elevated risks of COVID-19 incidence. This study highlights potential structural health inequalities within migrant communities, associated with lower socioeconomic status and a higher risk of COVID-19 incidence across diverse pandemic periods. Our findings indicate that locally tailored interventions for diverse citizens are essential to address health inequalities and foster a more sustainable urban environment.

description: Entropy-driven equilibrium phase behaviour of hard particle dispersions can be understood from excluded volume arguments only. While monodisperse hard spheres only exhibit a fluid-solid phase transition, anisotropic hard particles such as rods, discs, cuboids or boards exhibit various multi-phase equilibria. Ordering of such anisotropic particles increases the free volume entropy by reducing the excluded volume between them. The addition of depletants gives rise to an entropic patchiness represented by orientation-dependent attraction resulting in non-trivial phase behaviour. We show that free volume theory is a simple, generic and tractable framework that enables to incorporate these effects and rationalise various experimental findings. Plate-shaped particles constitute the main building blocks of clays, asphaltenes and chromonic liquid crystals that find widespread use in the food, cosmetics and oil industry. We demonstrate that mixtures of platelets and ideal depletants exhibit a strikingly rich phase behaviour containing several types of three-phase coexistence areas and even a quadruple region with four coexisting phases.

description: By supplanting survival with comfort, the environmental technologies ultimately increased the dependence of the building design on form and materials, particularly those of its ‘envelope.’ The emphasis on form and materials is best seen in the Brutalism Architecture where the “honesty in structure and material” is exhibited through the envelope. Brutalist is relevant to today’s digital fabrication techniques where materiality and fabrication methods are integrated with the realized building elements. For example, looking at 3D printed concrete, parallel and continuous layers of concrete placed on top of each other can be an indicator of the method, whereas seeing a smooth curved surface in a cast part can be an indicator of employing the molding method. Casting a malleable material such as concrete has multiple steps: creating a positive reference part, conceiving the formwork as the negative of the desired part, then pouring the liquid concrete, and finally demolding the hardened part. By employing 3D printing for creating the formwork, the first step of this process can be eliminated. In addition, limitations that a wood or steel formwork may impose on the part can be lifted. This paper looks at concrete elements used in building envelopes. It also reviews some recent projects regarding the design and fabrication of these modules with an interest in sculptural volumetric elements. It then provides an overview of students’ projects designing a volumetric self-standing shading screen using computational design tools and digital fabrication techniques, specifically 3D printed formwork. The pedagogy investigates challenges that students faced to break away from designing a “brick” mindset to designing topologically interlocking elements. The pedagogy demonstrates the complexities and opportunities that today’s advanced fabrication methods such as 3D printing can offer designers.

In this paper, we begin the study of the massless spectrum arising from compactification using this construction by counting zero modes of the linearized equations of motion for the gaugino in the supergravity approximation. We rephrase the question in terms of a cohomology problem and show that for a trivial gauge bundle, this cohomology reduces to the Dolbeault cohomology of the 3-fold, which we then compute.

description: Rapid increases in agent technology as well as the movement of computing into more and more social transactions has increased the need for embodied interface agents. However, interaction designers currently lack sufficient guidelines to confidently and successfully design the visual form of these agents. In this paper we offer a summary of research on the visual form of agents. In addition, we present our own study that explores the relationships between an agents visual form, the task it performs, and the demographics of users. As a result of the review and our own study, we frame the task of design of an agent’s form as being similar to “casting”. Finally, we offer some design guidelines to aid interaction designers in selecting human and non-human forms, in deciding how to address stereotypes, and in looking for opportunities to recast the agent’s visual form.

description: In this thesis we study one-variable fragments of first-order logics. Such a one-variable fragment consists of those first-order formulas that contain only unary predicates and a single variable. These fragments can be viewed from a modal perspective by replacing the universal and existential quantifier with a box and diamond modality, respectively, and the unary predicates with corresponding propositional variables. Under this correspondence, the one-variable fragment of first-order classical logic famously corresponds to the modal logic S5.

This thesis explores some such correspondences between first-order and modal logics. Firstly, we study first-order intuitionistic logics based on linear intuitionistic Kripke frames. We show that their one-variable fragments correspond to particular modal Gödel logics, defined over many-valued S5-Kripke frames. For a large class of these logics, we prove the validity problem to be decidable, even co-NP-complete. Secondly, we investigate the one-variable fragment of first-order Abelian logic, i.e., the first-order logic based on the ordered additive group of the reals. We provide two completeness results with respect to Hilbert-style axiomatizations: one for the one-variable fragment, and one for the one-variable fragment that does not contain any lattice connectives. Both these fragments are proved to be decidable. Finally, we launch a much broader algebraic investigation into one-variable fragments. We turn to the setting of first-order substructural logics (with the rule of exchange). Inspired by work on, among others, monadic Boolean algebras and monadic Heyting algebras, we define monadic commutative pointed residuated lattices as a first (algebraic) investigation into one-variable fragments of this large class of first-order logics. We prove a number of properties for these newly defined algebras, including a characterization in terms of relatively complete subalgebras as well as a characterization of their congruences.
RAINIER: A Simulation Tool for Distributions of Excited Nuclear States and Cascade Fluctuations

description: A new code has been developed named RAINIER that simulates the $γ$-ray decay of discrete and quasi-continuum nuclear levels for a user-specified range of energy, angular momentum, and parity including a realistic treatment of level spacing and transition width fluctuations. A similar program, DICEBOX, uses the Monte Carlo method to simulate level and width fluctuations but is restricted to $γ$-ray decay from no more than two initial states such as de-excitation following thermal neutron capture. On the other hand, modern reaction codes such as TALYS and EMPIRE populate a wide range of states in the residual nucleus prior to $γ$-ray decay, but do not go beyond the use of deterministic functions and therefore neglect cascade fluctuations. This combination of capabilities allows RAINIER to be used to determine quasi-continuum properties through comparison with experimental data. Several examples are given that demonstrate how cascade fluctuations influence experimental high-resolution $γ$-ray spectra from reactions that populate a wide range of initial states.

description: Refugees are frequently shown to have worse mental health outcomes than non-displaced populations. This fact is commonly attributed to traumatic pre-displacement experiences. While important, the focus on trauma risks overlooking the role socioeconomic living-conditions in different arrival and transit contexts can play in determining refugees’ mental distress. Building on the ecological model of refugee distress, we investigate how social ecological conditions relate to the mental distress of Syrians in Lebanon and Turkey. Both countries present important spaces of arrival and transit for millions of displaced Syrians, each with a specific historical, political, social and economic context. The empirical analysis is based on data gathered in early 2021 in face-to-face surveys among displaced Syrians in Lebanon (N = 1127) and Turkey (N = 1364). Individual mental distress is evaluated using the Patient Health Questionnaire (PHQ-8) score as the dependent variable in a multivariate regression analysis. Social ecological factors do not only differ in their extent of deprivation between Lebanon and Turkey. They also differ in their relationship with individual mental health outcomes. In Lebanon, limited access to the health care system and having family in the same city are major risk factors for elevated mental distress, whereas in Turkey, these are low education, poverty, unemployment as well as employment as day laborer. Discrimination and social isolation emerge as relevant predictors in both countries. Based on this analysis, we argue that a context-specific understanding of mental distress amidst the social ecology refugees face in countries of refuge and transit is necessary. This approach needs to be pursued to provide adequate support and alleviate refugees’ mental distress both, in the country of first refuge and after possible onward migration. In addition to clinical implications, the study particularly highlights the important role anti-discrimination and social inclusion policies could play in promoting refugee mental health.
Order From Confusion: International Chemical Standardization and the Elements, 1947-1990

description: The International Union of Pure and Applied Chemistry (IUPAC) is the international standards making body for chemistry whose goal is to create a standardized common language for the global chemistry community. The IUPAC governs the use and creation of names, symbols, and terminology. It also establishes criteria for the discovery of new elements and assesses discovery claims, develops of rules for naming new elements, and defines group numbering and collective names. Notably, the IUPAC does not recommend a specific form of the periodic table. This paper aims to explain why the IUPAC treats changes to the periodic table in a cautious manner by examining several occasions when they either changed nomenclature related to the elements or changed the periodic table. It shows that the negative reactions of chemical researchers to changes in nomenclature were relatively mild in comparison to those of chemical educators in the face of changes related to the periodic table.

Pseudo-3D Video Conferencing with a Generic Webcam

Subjects: Applied Computer Science

description: When conversing with someone via video conference, you are provided with a virtual window into their space. However, this currently remains both flat and fixed, limiting its immersiveness. Previous research efforts have explored the use of 3D in telecommunication, and show that the additional realism can enrich the video conference experience. However, existing systems require complex sensor and cameras setups that make them infeasible for widespread adoption. We present a method for producing a pseudo-3D experience using only a single generic webcam at each end. This means nearly any computer currently able to video conference can use our technique, making it readily adoptable. Although using comparatively simple techniques, the 3D result is convincing.

Periodicity Trees in a Secondary Criterion of Periodic Classification: Its Implications for Science Teaching and Communication
Creators: name: Zambon, Alfio
Publisher: name: Substantia
Year: 2019

description: In this work, I will present a proposal for introductory courses in chemistry. After the topics of atomic structure, chemical periodicity and chemical bonding, this proposal addresses the study of the periodic system based on triads, which has closed structures called periodicity trees as a secondary periodic criterion. This table was designed from a classical chemical perspective, with the purpose of integrating traditional topics and of supplying a conceptual basis for new ones, and, mainly, to privilege the chemical over the physical approach in the process of teaching-learning chemistry in initial courses.

description: In the present work we compute the spectrum of quasinormal frequencies of four-dimensional charged black holes in Einstein-power-Maxwell theory. In particular we study scalar perturbations adopting the 6th order WKB approximation. We analyze in detail the behaviour of the spectrum depending on the charge of the black hole, the quantum number of angular momentum and the overtone number. In addition, a comparison is made between the results obtained here and the results valid for charged black holes in other theories as well as for the Reissner-Nordstr${ö}$m black hole. Finally, we have provided an analytical expression for the quasinormal spectrum in the eikonal limit.

description: We suggest a novel picture of the quantum Universe -- its creation is described by the {\em density matrix} defined by the Euclidean path integral. This yields an ensemble of universes -- a cosmological landscape -- in a mixed state which is shown to be dynamically more preferable than the pure quantum state of the Hartle-Hawking type. The latter is dynamically suppressed by the infinitely large positive action of its instanton, generated by the conformal anomaly of quantum fields within the cosmological bootstrap (the self-consistent back reaction of hot matter). This bootstrap suggests a solution to the problem of boundedness of the on-shell cosmological action and eliminates the infrared catastrophe of small cosmological constant in Euclidean quantum gravity. The cosmological landscape turns out to be limited to a bounded range of the cosmological constant $Λ_{\rm min}\leq Λ\leq Λ_{\rm max}$. The domain $Λ

Julius Lothar (von) Meyer (1830-1895) and the Periodic System
Creators: name: Boeck, Gisela

description: The logo of the “International Year of the Periodic Table of Chemical Elements” (IYPT) shows only Dmitri I. Mendeleev (1834-1907) and none of the other scholars who were closely related with the discovery of the classification of elements. As early as 1864 the German physical chemist Lothar Meyer used a table to explain the “peculiar regularities” that were found among the atomic weights; by the end of that decade he had considered more elements and improved the system. Among other discoverers of the periodicity, Meyer and his colleague Karl Seubert (1851-1942) determined and recalculated atomic weights. This essay depicts the biography of Lothar Meyer and evaluates his contributions to the development of a classifi-cation system for chemical elements in several steps, to the periodic arrangement of elements. Finally, Meyer's opinion of the use of the periodic tables in teaching and organizing the material in courses on inorganic chemistry is presented.
