Predicting Outcomes in a Sequence of Binary Events: Belief Updating and Gambler's Fallacy Reasoning

description: We report on six experiments studying participants’ predictions of the next outcome in a sequence of binary events. Participants faced one of three mechanisms generating 18 sequences of 8 events: a random mechanical bingo cage, an intentional goal-directed actor, and a financial market. We systematically manipulated participants’ beliefs about the base rate probabilities at which different types of outcomes were generated by each mechanism. Participants either faced unknown (ambiguous) base rates, a specified distribution of three equiprobable base rates, or a precise, stationary base rate. Six target sequences ended in streaks of between two and seven identical outcomes. We focused on participants’ predictions of the ninth, unobserved outcome in each of these target sequences. Across all generating mechanisms and prior belief conditions, the most common prediction pattern was best described as close-to-rational belief updating, producing an increasingly strong bias toward repetition of streaks. The exception to this generalization was for sequences generated by a random mechanical bingo cage with a precise, stationary base rate of .50. Under these conditions, participants exhibited a bias toward reversal of streaks. This effect was irrational, given our instructions on the nature of the generator. We conclude that the dominant judgment habit when predicting outcomes of sequences of binary events is reasonable belief updating. We review alternate accounts for the anomalous judgments of sequences produced by random mechanical devices with a precise, stationary base rate.

description: Using high statistics datasets generated in (2+1)-flavor QCD calculations at finite temperature we present results for low order cumulants of net baryon-number fluctuations at non-zero values of the baryon chemical potential. We calculate Taylor expansions for the pressure (zeroth order cumulant), net baryon-number density (first order cumulant) and the variance of the distribution on net-baryon number fluctuations (second order cumulant). We obtain series expansions from an eighth order expansion of the pressure and compare these to diagonal Padé approximants. This allows us to estimate the range of values for the baryon chemical potential in which these expansions are reliable. We find $μ_B/T\le 2.5$, $2.0$ and $1.5$ for the zeroth, first and second order cumulants, respectively. We furthermore, construct estimators for the radius of convergence of the Taylor series of the pressure. In the vicinity of the pseudo-critical temperature, $T_{pc}\simeq 156.5$ MeV, we find $μ_B/T \gtrsim\ 2.9$ at vanishing strangeness chemical potential and somewhat larger values for strangeness neutral matter. These estimates are temperature dependent and range from $μ_B/T \gtrsim\ 2.2$ at $T=135$ MeV to $μ_B/T\ \gtrsim\ 3.2$ at $T=165$ MeV. The estimated radius of convergences is the same for any higher order cumulant.

description: This article contains a digest of the theory of electromagnetism and a review of the transformation between inertial frames, especially under low speed limits. The covariant nature of the Maxwell's equations is explained using the conventional language. We show that even under low speed limits, the relativistic effects should not be neglected to get a self-consistent theory of the electromagnetic fields, unless the intrinsic dynamics of these fields has been omitted completely. The quasi-static limits, where the relativistic effects can be partly neglected are also reviewed, to clarify some common misunderstandings and imprecise use of the theory in presence of moving media and other related situations. The discussion presented in this paper provide a clear view of why classical electromagnetic theory is relativistic in its essence.

Characterization of Supernovae Based on the Spectral-Temporal Energy Distribution: Possible two SN Ib Subtypes

description: A quantitative data-driven comparison among supernovae (SNe) based on their spectral time series combined with multi-band photometry is presented. We use an unsupervised Random Forest algorithm as a metric on a set of 82 well-documented SNe representing all the main spectroscopic types, in order to embed these in an abstract metric space reflecting shared correlations between the objects. We visualize the resulting metric space in 3D, revealing strong agreement with the current spectroscopic classification scheme. The embedding splits Type Ib supernovae into two groups, with one subgroup exhibiting broader, less prominent, higher-velocity lines than the other, possibly suggesting a new SN Ib subclass is required. The method could be to classify newly discovered SNe according to their distance from known event groups, or ultimately to devise a new, spectral-temporal classification scheme. Such an embedding could also depend on hidden parameters which may perhaps be physically interpretable.

Jahrhunderts einzufangen, Schulkindheiten und Schuljugenden in der Stadt zu konzeptionalisieren, zu definieren und zu kontrollieren. Dabei wird besonders auf Beschreibungen und Entwürfe einer bestimmten Gruppe von Lehrpersonen, aber auch auf Ansätze von Exponenten der Sozialpädagogik, Psychologie und der entstehenden Stadtsoziologie fokussiert. Die Konzeptionen changierten in ihren Bezugnahmen zwischen wissenschaftlichen Studien, Lehrmitteln und didaktischen Äusserungen, die im volksaufklärerischen Sinne nicht Teil der Eliten- oder Gebildetenkommunikation sein wollten, sondern auf Personen zielten, die in grossstädtischen und durch soziale Umbruchsituationen geprägten Milieus arbeiteten. Ob es auf die Frage nach der «guten» oder «richtigen» Schulkindheit in der Grossstadt seinerzeit nicht nur in wissenschaftsgestützten Debatten, sondern auch in sozialpolitischen Foren Auseinandersetzungen gegeben hat, soll mit in den Blick genommen werden.

description: The high-magnetic-field thermoelectric effect in nodal-line semimetals with straight nodal lines was investigated. Three-dimensional (3D) Dirac/Weyl semimetals exhibit constant thermoelectric Hall conductivity at the high-magnetic-field quantum limit, resulting in a boundless linear increase of Seebeck coefficient. This is known as the quantized thermoelectric Hall effect (QTHE), and is expected to lead to high-performance thermoelectricity at low temperatures. Here, in addition to Dirac/Weyl semimetals, we demonstrated that 3D semimetals with straight nodal lines can also exhibit the QTHE under high magnetic fields. As a candidate material for experimental validation, we discussed the thermoelectric properties of bulk graphite. Furthermore, we investigated the dimensional crossover of thermoelectricity to two-dimensional behavior in thin-film graphite.

description: Deep learning has revolutionised synthetic speech quality. However, it has thus far delivered little value to the speech science community. The new methods do not meet the controllability demands that practitioners in this area require e.g.: in listening tests with manipulated speech stimuli. Instead, control of different speech properties in such stimuli is achieved by using legacy signal-processing methods. This limits the range, accuracy, and speech quality of the manipulations. Also, audible artefacts have a negative impact on the methodological validity of results in speech perception studies. This work introduces a system capable of manipulating speech properties through learning rather than design. The architecture learns to control arbitrary speech properties and leverages progress in neural vocoders to obtain realistic output. Experiments with copy synthesis and manipulation of a small set of core speech features (pitch, formants, and voice quality measures) illustrate the promise of the approach for producing speech stimuli that have accurate control and high perceptual quality.

description: Methods that address data shifts usually assume full access to multiple datasets. In the healthcare domain, however, privacy-preserving regulations as well as commercial interests limit data availability and, as a result, researchers can typically study only a small number of datasets. In contrast, limited statistical characteristics of specific patient samples are much easier to share and may be available from previously published literature or focused collaborative efforts. Here, we propose a method that estimates model performance in external samples from their limited statistical characteristics. We search for weights that induce internal statistics that are similar to the external ones; and that are closest to uniform. We then use model performance on the weighted internal sample as an estimation for the external counterpart. We evaluate the proposed algorithm on simulated data as well as electronic medical record data for two risk models, predicting complications in ulcerative colitis patients and stroke in women diagnosed with atrial fibrillation. In the vast majority of cases, the estimated external performance is much closer to the actual one than the internal performance. Our proposed method may be an important building block in training robust models and detecting potential model failures in external environments.

description: For communication to happen successfully, a common language is required between agents to understand information communicated by one another. Inducing the emergence of a common language has been a difficult challenge to multi-agent learning systems. In this work, we introduce an alternative perspective to the communicative messages sent between agents, considering them as different incomplete views of the environment state. Based on this perspective, we propose a simple approach to induce the emergence of a common language by maximizing the mutual information between messages of a given trajectory in a self-supervised manner. By evaluating our method in communication-essential environments, we empirically show how our method leads to better learning performance and speed, and learns a more consistent common language than existing methods, without introducing additional learning parameters.

description: Through a qualitative survey among European researchers and interviews with policy makers we hope to enhance knowledge about interdisciplinary and transdisciplinary collaboration. The survey and interviews were carried out as part of Work Package 2 of the SHAPE-ID Horizon 2020 project (https://www.shapeid.eu), which is also conducting a systematic literature review. We aim to serve the research community and relevant stakeholders in society with new insights, examples of good practice and tips on how to overcome difficulties that might help their current and future interdisciplinary and transdisciplinary endeavours. We focus on Arts, Humanities and Social Sciences (AHSS), but are also interested in the growing collaboration between these fields and the so-called STEMM fields (Science, Technology, Engineering, Medicine and Mathematics). We address two main questions: (i) When developing a European interdisciplinary or transdisciplinary project, what are the main difficulties people encounter in realising a good research team that is balanced in terms of the various interests and goals of the different participants, and (ii) Which factors of success and failure do researchers integrating AHSS in larger projects consider relevant for their daily practice of interdisciplinary and transdisciplinary research?

description: We construct and explore a family of states for quantum systems in contact with two or more heath reservoirs. The reservoirs are described by equilibrium distributions. The interaction of each reservoir with the bulk of the system is encoded in a probability, which characterises the particle exchange among them and depends in general on the particle momentum. The convex combination of the reservoir distributions, weighted with the aforementioned probabilities, defines a new distribution. We establish the existence of an emission-absorption regime in which the new distribution generates a non-equilibrium quantum state. We develop a systematic field theory framework for constructing this state and illustrate its physical properties on a simple model. In this context we derive the particle current full counting statistics, the heat current and the Lorenz number. The entropy production and the relative quantum fluctuations are also determined.

description: Electromagnetic radiation in the mid- to far-infrared spectral range represents an indispensable tool for the study of numerous types of collective excitations in solids and molecules. Short and intense pulses in this THz spectral range are, however, difficult to obtain. While wide wavelength-tunability is easily provided by free-electron lasers, the energies of individual pulses are relatively moderate, on the order of microjoules. Here we demonstrate a setup that uses cavity-dumping of a free-electron laser to provide single, picosecond-long pulses in the mid- to far-infrared frequency range. The duration of the Fourier-limited pulses can be varied by cavity detuning, and their energy was shown to exceed 100 μJ. Using the aforementioned infrared pulse as a pump, we have realized a two-color pump-probe setup facilitating single-shot time-resolved imaging of magnetization dynamics. We demonstrate the capabilities of the setup first on thermally-induced demagnetization and magnetic switching of a GdFeCo thin film and second by showing a single-shot time-resolved detection of resonant phononic switching of the magnetization in a magnetic garnet.

description: At fixed stellar mass $M_*$, the effective radius $R_{\rm e}$ of massive satellite early-type galaxies (ETGs) in galaxy clusters is, on average, larger at lower redshift. We study theoretically this size evolution using the state-of-the-art cosmological simulation IllustrisTNG100: we sampled $75$ simulated satellite ETGs at redshift $z=0$ with $M_* \ge 10^{10.4} M_{\odot}$ belonging to the two most massive ($\approx 10^{14.6} M_{\odot} $) haloes of the simulation. We traced back in time the two clusters' main progenitors and we selected their satellite ETGs at $z>0$ with the same criterion adopted at $z=0$. The $R_{\rm e}-M_*$ relation of the simulated cluster satellite ETGs, which is robustly measured out to $z=0.85$, evolves similarly to the observed relation over the redshift range $0\lesssim z \lesssim 0.85$. In the simulation the main drivers of this evolution are the acquisition of new galaxies ("newcomers") by the clusters and the transformation of member galaxies located at large clustercentric distance ("suburbanites") at $z=0.85$, which end up being massive satellite ETGs at $z=0$. Though several physical processes contribute to change the population of satellite ETGs in the considered redshift interval, the shape of the stellar mass function of the simulated cluster ETGs is not significantly different at $z=0.85$ and at $z=0$, consistent with observations.

description: Several interesting physical systems, such as the Lovelock extension of General Relativity in higher dimensions, classical time crystals, k-essence fields, Horndeski theories, compressible fluids, and nonlinear electrodynamics, have apparent ill defined sympletic structures, due to the fact that their Hamiltonians are multi-valued functions of the momenta. In this paper, the dynamical evolution generated by such Hamiltonians is described as a degenerate dynamical system, whose sympletic form does not have a constant rank, allowing novel features and interpretations not present in previous investigations. In particular, it is shown how the multi-valuedness is associated with a dynamical mechanism of dimensional reduction, as some degrees of freedom turn into gauge symmetries when the system degenerates.

description: The proposed method, Neural Radiance Projection (NeRP), addresses the three most fundamental shortages of training such a convolutional neural network on X-ray image segmentation: dealing with missing/limited human-annotated datasets; ambiguity on the per-pixel label; and the imbalance across positive- and negative- classes distribution. By harnessing a generative adversarial network, we can synthesize a massive amount of physics-based X-ray images, so-called Variationally Reconstructed Radiographs (VRRs), alongside their segmentation from more accurate labeled 3D Computed Tomography data. As a result, VRRs present more faithfully than other projection methods in terms of photo-realistic metrics. Adding outputs from NeRP also surpasses the vanilla UNet models trained on the same pairs of X-ray images.

description: The IMPRESSIONS section of a radiology report about an imaging study is a summary of the radiologist's reasoning and conclusions, and it also aids the referring physician in confirming or excluding certain diagnoses. A cascade of tasks are required to automatically generate an abstractive summary of the typical information-rich radiology report. These tasks include acquisition of salient content from the report and generation of a concise, easily consumable IMPRESSIONS section. Prior research on radiology report summarization has focused on single-step end-to-end models -- which subsume the task of salient content acquisition. To fully explore the cascade structure and explainability of radiology report summarization, we introduce two innovations. First, we design a two-step approach: extractive summarization followed by abstractive summarization. Second, we additionally break down the extractive part into two independent tasks: extraction of salient (1) sentences and (2) keywords. Experiments on English radiology reports from two clinical sites show our novel approach leads to a more precise summary compared to single-step and to two-step-with-single-extractive-process baselines with an overall improvement in F1 score Of 3-4%.

description: We derive a particular approximate solution of Einstein equations, describing the gravitational field of a mass distribution that slightly deviates from spherical symmetry. The deviation is described by means of a quadrupole parameter that is responsible for the appearance of a curvature singularity, which is not covered by a horizon. We investigate the motion of test particles in the gravitational field of this naked singularity and show that the quadrupole parameter affects the properties of Schwarzschild trajectories. By investigating radial geodesics, we find that no effects of repulsive gravity are present. We interpreted this result as indicating that repulsive gravity is non-linear effect.

description: A água é o elemento mais importante e essencial para a vida humana e sua preservação tem sido pauta de discussões internacionais, uma vez que as interferências humanas têm sido a maior causadora do esgotamento. Para manter a preservação, o tratamento de esgoto é essencial. O problema é que, em geral, um sistema de tratamento convencional é muito acima do orçamento de comunidades onde cada habitante precisa sobreviver com menos de um salário mínimo. Surgiram, então, os sistemas de tratamento de esgoto alternativos, como as Wetlands (ambientes constituídos com plantas aquáticas, micro-organismos e meio filtrante como areia, cascalho e/ou outro material inerte). Esse método tem chamado atenção por seus custos relativamente baixos de operação e manutenção, simplicidade operacional e satisfatórios índices de remoção de poluentes. O presente trabalho contém um dimensionamento quantitativo e financeiro de uma Wetland de escoamento vertical do tipo francês aplicável para uma comunidade de 100 pessoas. Estudos indicam que a Wetland é de fácil construção, possui baixa manutenção e é mais barata de ser implementada do que um sistema convencional de tratamento. Foram detalhados todos os cálculos e passos necessários para o dimensionamento, com plantas baixas e vistas de como foi idealizada e algumas pontuações. O custo de implantação do projeto realizado chegou a R$49.669,10 em materiais, o que, comparado ao de um sistema convencional (uma média aproximada de R$700,00 por habitante), levam à conclusão de que as CWS são mais viáveis do que sistemas convencionais a comunidades de baixa renda.
Diagnostic and screening programs for fetal anomalies and genetic disease: how should we evaluate them?

description: I was asked to talk about evaluating diagnostic and screening programs for fetal anomalies; I'm going to take this to include genetic diseases as well, as they are so closely related. I am going to talk about programs that are aimed at detecting prenatally whether the fetus has a genetic disease or a physical anomaly. I am not going to address newborn or other screening. I will tell you what we have learned from Commission research about how prenatal programs are currently used in Canada, talk about developments on the horizon, and mention some of the issues raised by such programs. I will conclude my talk by describing the usual approach to evaluating prenatal diagnostic and screening programs, pointing out some of the detrimental effects of this approach, and outlining an alternative.

description: Digital systems for analyzing human communication data have become prevalent in recent years. Intelligence analysis of communications data in investigative journalism, criminal intelligence, and law present particularly interesting cases, as they must take into account the often highly sensitive properties of the underlying operations and data. At the same time, these are areas where increasingly automated, sophisticated approaches systems can be particularly relevant, especially in terms of Big Data manageability. However, by the shifting of responsibilities, this also poses dangers. In addition to privacy concerns, these dangers relate to uncertain or poor data quality, leading to discrimination and potentially misleading insights. Visual analytics combines machine learning methods with interactive visual interfaces to enable human sense- and decision-making. This technique can be key for designing and operating meaningful interactive communication analysis systems that consider these ethical challenges. In this interdisciplinary work, a joint endeavor of computer scientists, ethicists, and scholars in Science & Technology Studies, we investigate and evaluate opportunities and risks involved in using Visual analytics approaches for communication analysis in intelligence applications in particular. We introduce, at first, the common technological systems used in communication analysis, further discussing the domain-specific ethical implications, tensions, and risks involved. We then make the case of how tailored Visual Analytics approaches may reduce and mitigate the described problems, both theoretically and through practical examples. We show that finding Visual Analytics design solutions for ethical issues is not a mere optimization task, but balancing out and negotiating these trade-offs has, as we argue, to be an integral aspect of the system design process from the outset.

description: The critical heat flux (CHF) is an important thermal-hydraulic parameter that must be determined during the design of water-cooled reactors to ensure safety of operation. In this paper, a methodology is proposed to predict the CHF in VVER rod bundles. A whole-reactor model of VVER-1000 is implemented in RELAP-SCDAPSIM, and, based on the bundle-average approach, the parameters of the hot channel are used to assess four CHF predictors (i.e., the 2006 Groeneveld look-up table (LUT), and the Bowring, W-3, Biasi, and OKB-Gidropress correlations) upon comparison with the 2011 Bobkov LUT. A brief critique is given of the correction factors for both the Groeneveld and Bobkov LUTs. The effects of channel diameter and non-uniform axial heat flux on the predicted values of CHF in subcooled conditions are also studied. The performance and time complexity of the standard and Bourke trilinear interpolation algorithms are assessed for use with LUTs in safety codes. It has been concluded that the non-uniform axial heat flux does not affect the CHF in subcooled conditions and that the Groeneveld diameter factor exponent gives better predictability of the CHF in VVER rod bundles over the Tanase and Wong exponent correlations. Additionally, the Groeneveld LUT has been found to nearly reproduces the Bobkov LUT CHF values when used in conjunction with the Bobkov heated length factor. Values of MDNBR equal to 1.83 and 1.96 can be used as thermal limits at 12\% overpower when the Bowring and W-3 correlations, respectively, are used in subcooled conditions. The standard and Bourke algorithms nearly exhibit the same average CPU time. The Bourke algorithm, however, is less affected by noise. Further research is needed to ensure the smoothness of the Bobkov LUT and to derive reactor type-dependent correction factor formulas for use with the Groeneveld LUT.

description: Bioactive glasses release ions such as sodium when implanted in the human body. However, an excess of the released ions can cause problems related to cytotoxicity. The ion release control is considered one of the primary challenges in developing new bioactive glasses. Here, we use molecular dynamics simulations to investigate the effect of the density on atoms' dynamics in an archetypal phosphosilicate bioactive system. The diffusion coefficient displays three main regimes with increasing density. The mobility of the modifiers is significantly affected by the increase of the density, especially Na, compared to other elements. We use a modified Arrhenian model to access the complex dynamic behavior of 45S5 melts and correlate it to the structural changes by evaluating the network connectivity and pair-excess entropy. Overall, our results present a step toward the rational design of bioactive glasses and a key to controlling the ion release of bioactive glasses.
