description: The equation of state of hydrogen, helium, and water effects interior structure models of giant planets significantly. We present a new equation of state data table, LM-REOS, generated by large scale quantum molecular dynamics simulations for hydrogen, helium, and water in the warm dense matter regime, i.e.for megabar pressures and temperatures of several thousand Kelvin, and by advanced chemical methods in the complementary regions. The influence of LM-REOS on the structure of Jupiter is investigated and compared with state-of-the-art results within a standard three-layer model consistent with astrophysical observations of Jupiter. Our new Jupiter models predict an important impact of mixing effects of helium in hydrogen with respect to an altered compressibility and immiscibility.

An Investigation of the Bound State Solutions of the Klein-Gordon Equation for the Generalized Woods-Saxon Potential in Spin Symmetry and Pseudo-spin Symmetry Limits

description: Recently, scattering of a Klein-Gordon particle in the presence of mixed scalar-vector generalized symmetric Woods-Saxon potential was investigated for the spin symmetric and the pseudo-spin symmetric limits in one spatial dimension. In this manuscript, the bound state solutions of the Klein-Gordon equation with mixed scalar-vector generalized symmetric Woods-Saxon potential are examined analytically within the framework of spin and pseudo-spin symmetry limits. We prove that the occurrence of bound state energy spectrum exists only in the spin symmetric limit, while in the pseudo-spin symmetric limit, the bound state spectrum does not exist. Besides the theoretical proof, the Newton-Raphson numerical methods are used to calculate the bound state energy spectra of a neutral Kaon particle, confined in a generalized symmetric Woods-Saxon potential, energy well constituted with repulsive or attractive surface interactions, for the spin and pseudo-spin symmetric limits, respectively. Numerical results are consistent with the non-existence of the bound state energy spectrum in the pseudo-spin symmetric limit.

Media/lity – Between Image Ban and Eucharist
Creators: name: Van Oorschot, Frederike
name: Höhne, Florian
Publisher: name: Cursor_
Year: 2024

description: In this paper, we want to reflect digital media’s function to bridge absent entities theologically, inspired by two discourses: the thinking about the biblical image-ban after the iconic turn on the one hand and the debates about the Lord’s Supper on the other. Of course, this will not lead to a full theory or concept of media and mediality. But it leads to the following main suggestions: We will argue, that the common dualities of “reality” vs. “virtuality” and “embodied” vs. “disembodied” are not appropriate for reflecting digital mediality. Rather, the difference between different media and different media-practices is decisive. This difference is also more decisive than the difference between seemingly unmediated presence and mediated presence. The focus on media all too often hides that seemingly unmediated practices are media practices as well. We will show how different practices – particularly the practice of Eucharist – are already media practices that partake in the dialectic between presence and absence, between making present and withdrawal.

Exploring Multiple Dimensions of Parallelism in Junction Tree Message Passing

description: Belief propagation over junction trees is known to be computationally challenging in the general case. One way of addressing this computational challenge is to use node-level parallel computing, and parallelize the computation associated with each separator potential table cell. However, this approach is not efficient for junction trees that mainly contain small separators. In this paper, we analyze this problem, and address it by studying a new dimension of node-level parallelism, namely arithmetic parallelism. In addition, on the graph level, we use a clique merging technique to further adapt junction trees to parallel computing platforms. We apply our parallel approach to both marginal and most probable explanation (MPE) inference in junction trees. In experiments with a Graphics Processing Unit (GPU), we obtain for marginal inference an average speedup of 5.54x and a maximum speedup of 11.94x; speedups for MPE inference are similar.
Batalin-Vilkovisky algebras and two-dimensional topological field theories

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

description: Batalin-Vilkovisky algebras are a new type of algebraic structure on graded vector spaces, which first arose in the work of Batalin and Vilkovisky on gauge fixing in quantum field theory. In this article, we show that there is a natural structure of a Batalin-Vilkovisky algebra on the cohomology of a topological field theory in two dimensions. Lian and Zuckerman have constructed this Batalin-Vilkovisky structure, in the setting of topological chiral field theories, and shown that the structure is non-trivial in two-dimensional string theory. Our approach is to use algebraic topology, whereas their proofs have a more algebraic character.

description: Cricket ultrasound locationing devices are employed to support SmartSpaces, a ubiquitous smart computing research environment at Carnegie Mellon University Silicon Valley. A key requirement for realization of the SmartSpaces vision is a robust (interior) location-reporting system. This paper discusses some early CMU Silicon Valley experiments with Crickets within the context of the SmartSpaces project with an interior setting. Cricket hardware strengths and weaknesses are evaluated and reported in the context of controlling a Roomba robot vacuum. Experiences using Crickets to guide Roomba navigation are discussed.
Empathy in an Age of Deepfakes
Creators: name: Anderson, Clifford
Publisher: name: Cursor_
Year: 2024

description: What is the potential of empathy in helping us see through and beyond deepfakes? Deepfakes are synthetic media that depict individuals acting in falsified circumstances. With growing concern about the propagandistic uses of deepfakes, researchers are actively working on countermeasures to detect synthetic media. This paper examines whether empathy can play a role in differentiating deepfakes from genuine media. After exegeting the phenomenological interpretation of empathy in the works of Edmund Husserl and Edith Stein, the paper explores whether empathy could play a gnoseological role in an interdisciplinary campaign against deepfakes.

description: The objective of this Deliverable D1.1 Stocktaking Report is to present the results of Task 1.1 of Work Package 1 (WP1) and wants to provide a stocktaking analysis and synthesis of the successful and failed practices in the implementation of RRI, as well as carefully reflect on differences in terms of organisations, cultural factors, context requirements, drivers, barriers and challenges of RRI in the organisational domain. The analysis consisted of a systematic literature review of 29 papers, a stocktaking of 23 EU funded projects and the conclusions of 3 virtual workshops with EU RRI project representatives and experts. The analysis was structured based on an initial framework around the two main topics for identifying and analysing focal key issues in literature and previous RRI projects: organizational change theory and RRI. This report articulates the stocktaking synthesis with the identification of two major drivers that can facilitate the adoption of RRI (societal challenges and distribution of responsibilities in R&D ecosystems), five pillars that sum up the empirical evidence gathered around RRI and organizational change (adapting the process to the degree of institutionalization, ecosystem & context, organizational theory, culture, communication and trust, and metrics and indicators), and two windows of opportunity for implementing RRI (RRIsing smart specialisation strategies, RRI as tool for institutional learning).

description: Devices relying on microwave circuitry form a cornerstone of many classical and emerging quantum technologies. A capability to provide in-situ, noninvasive and direct imaging of the microwave fields above such devices would be a powerful tool for their function and failure analysis. In this work, we build on recent achievements in magnetometry using ensembles of nitrogen vacancy centres in diamond, to present a widefield microwave microscope with few-micron resolution over a millimeter-scale field of view, 130nT/sqrt-Hz microwave amplitude sensitivity, a dynamic range of 48 dB, and sub-ms temporal resolution. We use our microscope to image the microwave field a few microns above a range of microwave circuitry components, and to characterise a novel atom chip design. Our results open the way to high-throughput characterisation and debugging of complex, multi-component microwave devices, including real-time exploration of device operation.

Interrogating the Church’s Relationship to Technology Through Pandemic Internet Memes

description: This paper explores how studying memes can reveal popular narratives that people hold about the relationship between technology and the church, informing perceptions of the move from offline to online worship services during the COVID-19 global pandemic. Of most interest in this article are the stories that memes tell about religion and religious groups during the pandemic related to technology. I argue that this provides a unique insight into the Digital Theology that is emerging out of the COVID-19 pandemic, or the dominant theological assumption about technology widely circulate online and promoted via memes.

description: Using a sample of 1.8 million DDbar meson pairs collected at the psi(3770) with the CLEO-c detector, we study the semileptonic decays D^0 -> pi^- e^+ nu_e, D^+ -> pi^0 e^+ ν_e, D^0 -> K^- e^+ ν_e, and D^+ -> Kbar^0 e^+ nu_e. For the total branching fractions we find B(D^0 -> pi^- e^+ ν_e) = 0.299(11)(9)%, B(D^+ -> pi^0 e^+ ν_e) = 0.373(22)(13)%, B(D^0 -> K^- e^+ nu_e) = 3.56(3)(9)%, and B(D^+ -> Kbar^0 e^+ nu_e) = 8.53(13)(23)%, where the first error is statistical and the second systematic. In addition, form factors are studied through fits to the partial branching fractions obtained in five q^2 ranges. By combining our results with recent unquenched lattice calculations, we obtain |Vcd| = 0.217(9)(4)(23) and |Vcs| = 1.015(10)(11)(106), where the final error is theoretical.

description: The electrodynamic response of organic spin liquids with highly-frustrated triangular lattices has been measured in a wide energy range. While the overall optical spectra of these Mott insulators are governed by transitions between the Hubbard bands, distinct in-gap excitations can be identified at low temperatures and frequencies which we attribute to the quantum spin liquid state. For the strongly correlated $β^{\prime}$-EtMe$_3$\-Sb\-[Pd(dmit)$_2$]$_2$, we discover enhanced conductivity below $175~{\rm cm}^{-1}$, comparable to the energy of the magnetic coupling $J\approx 250$ K. For $ω\rightarrow 0$ these low-frequency excitations vanish faster than the charge-carrier response subject to Mott-Hubbard correlations, resulting in a dome-shape band peaked at 100~\cm. Possible relations to spinons, magnons and disorder are discussed.

description: We must consider: how does the image of the network relate to other ecclesiological descriptions of the church? I propose we sharpen the image of the network in order to clarify its ecclesiological potentials and limits. This is of particular interest because the “network” is widely discussed not only in the field of digital church life but also in practical theology with a view to analog and digital church life. In the context of this conference and referring to the broad oeuvre of Heidi Campbell on this issue I will primarily focus on the debate about digital ecclesiology in the broader field of digital theology.

description: We perform statistical mechanics calculations to analyze the global phase diagram of a fully-connected version of a Maier-Saupe-Zwanzig lattice model with the inclusion of couplings to an elastic strain field. We point out the presence of uniaxial and biaxial nematic structures, depending on temperature $T$ and on the applied stress $σ$. Under uniaxial extensive tension, applied stress favors uniaxial orientation, and we obtain a first-order boundary, along which there is a coexistence of two uniaxial paranematic phases, and which ends at a simple critical point. Under uniaxial compressive tension, stress favors biaxial orientation; for small values of the coupling parameters, the first-order boundary ends at a tricritical point, beyond which there is a continuous transition between a paranematic and a biaxially ordered structure. For some representative choices of the model parameters, we obtain a number of analytic results, including the location of critical and tricritical points and the line of stability of the biaxial phase.

Wearable sensing for continuous free tissue transfer monitoring
Creators: name: Berthelot, Melissa
Publisher: name: Imperial College London
Year: 2018

description: Pervasive sensing has rapidly grown over the last decade to provide more accurate and reliable measurements with advanced on node data analysis. Already adapted in many fields, such as communication, transportation and the food industry, pervasive sensing has enabled a new industry revolution, from production, logistics to management and marketing forecast. Pervasive sensing is also considered a suitable technical approach to tackle the growing demand on health care services. From hospital and home care to everyday wear, pervasive sensing has the potential to provide continuous monitoring of vital signs, assist in the diagnosis of pathologies and early detect exacerbations in chronic diseases. Specifically to hospitals, continuous monitoring with connected devices can assist the clinical staff and reduce their workload by alarming them only when abnormalities are detected. Currently, there is a limited number of connected monitoring devices used in the clinical setting that provide continuous monitoring at bed side. This research proposes a platform which integrates connected wearable devices to provide continuous measurements of blood flow and perfusion parameters. The platform also allows ubiquitous and real time access to contextual information deduced from the measurements with a designed mobile application and an online server. It aims to provide continuous monitoring of tissue oxygen saturation (StO2) and arterial pulse (AP) to assist the clinical team in decision making and allow them to observe blood flow and perfusion evolution. The platform was tested on healthy volunteer humans, animals and patients in a clinical study for the application of postoperative free tissue transfer (FTT) monitoring performed for breast reconstruction following mastectomy. The results show the integrated platform and the wearable devices provide accurate and reliable measurements, independently to the patients anthropometric details and its environment, while ergonomically fitting in the clinical setting. An additional clinical translation was carried using the platform as a training tool for objective monitoring of the evolution of microsurgical skills in the case of vascular repair tasks.

description: Joint analysis of security and routing protocols in wireless networks reveals vulnerabilities of secure network traffic that remain undetected when security and routing protocols are analyzed independently. We formulate a class of continuous metrics to evaluate the vulnerability of network traffic as a function of security and routing protocols used in wireless networks. We develop two complementary vulnerability definitions using set theoretic and circuit theoretic interpretations of the security of network traffic, allowing a network analyst or an adversary to determine weaknesses in the secure network. We formalize node capture attacks using the vulnerability metric as a nonlinear integer programming minimization problem and propose the GNAVE algorithm, a Greedy Node capture Approximation using Vulnerability Evaluation. We discuss the availability of security parameters to the adversary and show that unknown parameters can be estimated using probabilistic analysis. We demonstrate vulnerability evaluation using the proposed metrics and node capture attacks using the GNAVE algorithm through detailed examples and simulation.

description: Digitization is a sometimes radical, sometimes very subtle process of transformation in all areas of our social, church and personal lives. The Corona pandemic in particular has once again brought this home and led to a sharp increase in digital communication in many areas of life. Sound theoretical modeling and theological reflection often lag behind real developments and the imaginaries spun around them. What can theological reflection contribute to the analysis, conceptualization, and evaluation of the emerging logics and narratives of the digital age? Conversely, how is theology challenged to interrogate the way it thinks about particular issues?

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: If a fourth generation of leptons exists, both the neutrino and its charged partner must be heavier than 45 GeV. We suppose that the neutrino is the heavier of the two, and that a global or discrete symmetry prohibits intergenerational mixing. In that case, non-renormalizable Planck scale interactions will induce a very small mixing; dimension five interactions will lead to a lifetime for the heavy charged lepton of $O(1-100)$ years. Production of such particles is discussed, and it is shown that a few thousands can be produced and collected at a linear collider. The possible uses of these heavy leptons is also briefly discussed.

description: We describe and employ a stacking procedure to investigate abundances derived from the low S/N spectra obtained in the Carnegie RR Lyrae Survey (CARRS; Kollmeier et al. 2013). We find iron metallicities that extend from [Fe/H] ~ -2.5 to values at least as large as [Fe/H] ~ -0.5 in the 274-spectrum CARRS RRc data set. We consider RRc sample contamination by high amplitude solar metallicity delta Scuti stars (HADS) at periods less than 0.3 days, where photometric discrimination between RRc and delta Scuti stars has proven to be problematic. We offer a spectroscopic discriminant, the well-marked overabundance of heavy elements, principally [Ba/H], that is a common, if not universal, characteristic of HADS of all periods and axial rotations. No bona fide RRc stars known to us have verified heavy-element overabundances. Three out of 34 stars in our sample with [Fe/H] > -0.7 exhibit anomalously strong features of Sr, Y, Zr, Ba, and many rare earths. However, carbon is not enhanced in these three stars, and we conclude that their elevated n-capture abundances have not been generated in interior neutron-capture nucleosynthesis. Contamination by HADS appears to be unimportant, and metal-rich RRc stars occur in approximately the same proportion in the Galactic field as do metal-rich RRab stars. An apparent dearth of metal-rich RRc is probably a statistical fluke. Finally we show that RRc stars have a similar inverse period-metallicity relationship as has been found for RRab stars.

description: A current challenge for ab initio calculations is systems that contain large continuum contributions such as 8Be. We report on new measurements of radiative decay widths in this nucleus that test recent Green's function Monte Carlo calculations. Traditionally, γ ray detectors have been utilized to measure the high energy photons from the 7Li(p, γ)αα reaction. However, due to the complicated response function of these detectors it has not yet been possible to extract the full γ ray spectrum from this reaction. Here we present an alternative measurement using large area Silicon detectors to detect the two α particles, which provides a practically background free spectrum and retains good energy resolution. The resulting spectrum is analyzed using a many-level multi channel R-matrix parametrization. Improved values for the radiative widths are extracted from the R-matrix fit. We find evidence for significant non-resonant continuum contributions and tentative evidence for a broad 0+ resonance at 12 MeV.

description: We show that a class of type IIA vacua recently found within the N=4 effective approach corresponds to compactification on Ads_4 \times S^3 \times S^3/Z_2^3. The results obtained using the effective method completely match the general ten-dimensional analysis for the existence of N=1 warped compactifications on Ads_4 \times M_6. In particular, we verify that the internal metric is nearly-Kahler and that for specific values of the parameters the Bianchi identity of the RR 2-form is fulfilled without sources. For another range of parameters, including the massless case, the Bianchi identity is satisfied when D6-branes are introduced. Solving the tadpole cancellation conditions in D=4 we are able to find examples of appropriate sets of branes. In the second part of this paper we describe how an example with internal space CP^3 but with non nearly-Kahler metric fits into the general analysis of flux vacua.

description: We use N-body simulations of bar formation in isolated galaxies to study the effect of bulge mass and bulge concentration on bar formation. Bars are global disk instabilities that evolve by transferring angular momentum from the inner to outer disks and to the dark matter halo. It is well known that a massive spherical component such as halo in a disk galaxy can make it bar stable. In this study we explore the effect of another spherical component, the bulge, on bar formation in disk galaxies. In our models we vary both the bulge mass and concentration. We have used two sets of models, one that has a dense bulge and high surface density disk. The second model has a less concentrated bulge and a lighter disk. In both models we vary the bulge to disk mass fraction from 0 to 0.7. Simulations of both the models show that there is an upper cutoff in bulge to disk mass ratio M b /M d above which bars cannot form; the cutoff is smaller for denser bulges( M b /M d = 0.2) compared to less denser ones (M b /M d = 0.5). We define a new criteria for bar formation in terms of bulge to disk radial force ratio (F b /F d ) at the disk scale lengths above which bars cannot form. We find that if F b /F d > 0.35, a disk is stable and a bar cannot form. Our results indicate that early type disk galaxies can still form strong bars in spite of having massive bulges.

description: In this paper we have investigated the gravitational lensing in a spherically symmetric spacetime with torsion in the generalized Einstein-Cartan-Kibble-Sciama (ECKS) theory of gravity by considering higher order terms. The torsion parameters change the spacetime structure which affects the photon sphere, the deflection angle and the strong gravitational lensing. The condition of existence of horizons is not inconsistent with that of the photon sphere. Especially, there exists a novel case in which there is horizon but no photon sphere for the considered spacetime. In this special case, the deflection angle of the light ray near the event horizon also diverges logarithmically, but the coefficients in the strong-field limit are different from those in the cases with photon sphere. Moreover, in the far-field limit, we find that the deflection angle for certain torsion parameters approaches zero from the negative side, which is different from those in the usual spacetimes.

description: We present the quantization of the Liouville model defined in light-cone coordinates in (1,1) signature space. We take advantage of the representation of the Liouville field by the free field of the Backlünd transformation and adapt the approch by Braaten, Curtright and Thorn. Quantum operators of the Liouville field $\partial_{+}ϕ$, $\partial_{-}ϕ$, $e^{gϕ}$, $e^{2gϕ}$ are constructed consistently in terms of the free field. The Liouville model field theory space is found to be restricted to the sector with field momentum $P_{+}=-P_{-}$, $P_{+}> 0$ , which is a closed subspace for the Liouville theory operator algebra.

description: We consider entanglement-assisted (EA) private communication over a quantum broadcast channel, in which there is a single sender and multiple receivers. We divide the receivers into two sets: the decoding set and the malicious set. The decoding set and the malicious set can either be disjoint or can have a finite intersection. For simplicity, we say that a single party Bob has access to the decoding set and another party Eve has access to the malicious set, and both Eve and Bob have access to the pre-shared entanglement with Alice. The goal of the task is for Alice to communicate classical information reliably to Bob and securely against Eve, and Bob can take advantage of pre-shared entanglement with Alice. In this framework, we establish a lower bound on the one-shot EA private capacity. When there exists a quantum channel mapping the state of the decoding set to the state of the malicious set, such a broadcast channel is said to be degraded. We establish an upper bound on the one-shot EA private capacity in terms of smoothed min- and max-entropies for such channels. In the limit of a large number of independent channel uses, we prove that the EA private capacity of a degraded quantum broadcast channel is given by a single-letter formula. Finally, we consider two specific examples of degraded broadcast channels and find their capacities. In the first example, we consider the scenario in which one part of Bob's laboratory is compromised by Eve. We show that the capacity for this protocol is given by the conditional quantum mutual information of a quantum broadcast channel, and so we thus provide an operational interpretation to the dynamic counterpart of the conditional quantum mutual information. In the second example, Eve and Bob have access to mutually exclusive sets of outputs of a broadcast channel.

description: It is argued that color transparency in quasi elastic scattering of electrons and hadrons on nuclei is possible only due to Fermi-motion. We found a strong dependence of nuclear transparency on Bjorken x in (e,e'p), it is close to the Glauber model expectations at $x>1$, but increases and even exceeds one at $x<1$. It is argued that color transparency is accompanied by large longitudinal momentum transfer to nuclear matter during the passage of the small size wave packet. \vspace{\fill}

description: Many context-aware mobile applications require a reasonably accurate and stable estimate of a user’s location. While the Global Positioning System (GPS) works quite well world-wide outside of buildings and urban canyons, locating an indoor user in a real-world environment is much more problematic. Several different approaches and technologies have been explored, some involving specialized sensors and appliances, and others using increasingly ubiquitous Wi- Fi and Bluetooth radios. In this project, we want to leverage existing Wi-Fi access points (AP) and seek efficient approaches to gain usefully high room-level accuracy of the indoor location prediction of a mobile user. The Redpin algorithm, in particular, matches the Wi-Fi signal received with the signals in the training data and uses the position of the closest training data as the user's current location. However, in a congested Wi-Fi environment where many APs exist, the standard Redpin algorithm can become confused because of the unstable radio signals received from too many APs. In this paper, we propose several enhanced indoor-locationing algorithms for the congested Wi-Fi environment. Different statistical learning algorithms are compared and empirical results show that: using more neighbors gives better results than using the 1-best neighbor; weighting APs with the correlation between the AP visibility and the location is better than the equally weighted AP combination, and automatic filtering noisy APs increases the overall detection accuracy. Our experiments in a university building show that our enhanced indoor locationing algorithms significantly outperform the-state-of-the-art Redpin algorithm. In addition, this paper also reports our findings on how the size of the training data, the physical size of the room and the number of APs affect the accuracy of indoor locationing.

description: We study a nonparametric Bayesian approach to linear inverse problems under discrete observations. We use the discrete Fourier transform to convert our model into a truncated Gaussian sequence model, that is closely related to the classical Gaussian sequence model. Upon placing the truncated series prior on the unknown parameter, we show that as the number of observations $n\rightarrow\infty,$ the corresponding posterior distribution contracts around the true parameter at a rate depending on the smoothness of the true parameter and the prior, and the ill-posedness degree of the problem. Correct combinations of these values lead to optimal posterior contraction rates (up to logarithmic factors). Similarly, the frequentist coverage of Bayesian credible sets is shown to be dependent on a combination of smoothness of the true parameter and the prior, and the ill-posedness of the problem. Oversmoothing priors lead to zero coverage, while undersmoothing priors produce highly conservative results. Finally, we illustrate our theoretical results by numerical examples.
