description: I briefly review the method of population synthesis of binary stars and discuss the preliminary results of a study of the Galactic population of subdwarf B stars. In particular I focus on the formation of (apparently) single sdB stars and their relation to (apparently) single helium-core white dwarfs. I discuss the merits of mergers of two helium white dwarfs and interactions with sub-stellar companions for explaining these single objects. A preliminary conclusion is that the current observations suggest both mechanisms may contribute, but that the helium white dwarfs are likely formed in majority from interactions with sub-stellar companions.

description: The question at which layer network functionality is presented or abstracted remains a research challenge. Traditionally, network functionality was either placed into the core network, middleboxes, or into the operating system -- but recent developments have expanded the design space to directly introduce functionality into the application (and in particular into the browser) as a way to expose it to the user. Given the context of emerging path-aware networking technology, an interesting question arises: which layer should handle the new features? We argue that the browser is becoming a powerful platform for network innovation, where even user-driven properties can be implemented in an OS-agnostic fashion. We demonstrate the feasibility of geo-fenced browsing using a prototype browser extension, realized by the SCION path-aware networking architecture, without introducing any significant performance overheads.

description: In den letzten Jahren hat sich die Vermittlung von Informationskompetenz zu einer der zentralen Aufgaben von wissenschaftlichen Bibliotheken entwickelt. Während sich Präsenzschulungen für unterschiedliche Zielgruppen bereits in den meisten Bibliotheken etabliert haben, sind Angebote, die sich elektronischer Medien bedienen, weniger weit verbreitet; dies trifft besonders auf die Form des Webinars, eines virtuellen Seminars, zu. Vor diesem Hintergrund wurde im Rahmen einer Hausarbeit in der Referendarsausbildung eine Bestandserhebung zum Angebot von Webinaren an deutschsprachigen wissenschaftlichen Bibliotheken im Wintersemester 2013/2014 durchgeführt. In diesem Beitrag wird der Status quo des Angebots an Webinaren auf gezeigt und Perspektiven, die Webinare für Bibliotheken bieten können, erörtert.

description: Quasar absorption line analysis is critical for studying gas and dust components and their physical and chemical properties as well as the evolution and formation of galaxies in the early universe. Ca II absorbers, which are one of the dustiest absorbers and are located at lower redshifts than most other absorbers, are especially valuable when studying physical processes and conditions in recent galaxies. However, the number of known quasar Ca II absorbers is relatively low due to the difficulty of detecting them with traditional methods. In this work, we developed an accurate and quick approach to search for Ca II absorption lines using deep learning. In our deep learning model, a convolutional neural network, tuned using simulated data, is used for the classification task. The simulated training data are generated by inserting artificial Ca II absorption lines into original quasar spectra from the Sloan Digital Sky Survey (SDSS) whilst an existing Ca II catalog is adopted as the test set. The resulting model achieves an accuracy of 96% on the real data in the test set. Our solution runs thousands of times faster than traditional methods, taking a fraction of a second to analyze thousands of quasars while traditional methods may take days to weeks. The trained neural network is applied to quasar spectra from SDSS's DR7 and DR12 and discovered 399 new quasar Ca II absorbers. In addition, we confirmed 409 known quasar Ca II absorbers identified previously by other research groups through traditional methods.

description: In 1911, Jüttner proposed the generalization, for a relativistic gas, of the Maxwell-Boltzmann distribution of velocities. Here we want to discuss, among others, Jüttner probability density function (PDF). Both the velocity space and, consequently, the momentum space are not flat in special relativity. The velocity space corresponds to the Lobachevsky one, which has a negative curvature. This curvature induces a specific power for the Lorentz factor in the PDF, affecting Jüttner normalization constant in one, two, and three dimensions. Furthermore, Jüttner distribution, written in terms of a more convenient variable, the rapidity, presents a curvature change at the origin at sufficiently high energy, which does not agree with our computational dynamics simulations of a relativistic gas. However, in one dimension, the rapidity satisfies a simple additivity law. This allows us to obtain, through the Central Limit Theorem, a new, Lorentz-invariant, PDF whose curvature at the origin does not change for any energy value and which agrees with our computational dynamics simulations data. Also, we perform extensive first-principle simulations of a one-dimensional relativistic gas constituted by light and heavy particles.

description: We report new near-infrared and mm-wave observational data on a selection of massive Galactic molecular clumps (part of the CHaMP sample) and their associated young star clusters. The clumps show, for the first time in a "dense gas tracer", a significant correlation between HCO+ line emission from cold molecular gas and Brγ line emission of associated nebulae. This correlation arises in the HCO+ line's brightness, not its linewidth. In contrast, the correlation between the N2H+ line emission and Brγ is weak or absent. The HCO+/N2H+ line ratio also varies widely from clump to clump: bright HCO+ emission tends to be more closely associated with Brγ nebulosity, while bright N2H+ emission tends to avoid areas that are bright in Brγ. Both molecular species show correlations of weak significance with infrared H2 v=1-0 and v=2-1 line emission, in or near the clumps. The H2 emission line ratio is consistent with fluorescent excitation in most of the clumps, although thermal excitation is seen in a few clumps. We interpret these trends as evidence for evolution in the gas conditions due to the effects of ongoing star formation in the clumps, in particular, the importance of UV radiation from massive YSOs as the driving agent that heats the molecular gas and alters its chemistry. This suggests that some traditional dense gas tracers of molecular clouds do not sample a homogeneous population of clumps, i.e., that the HCO+ brightness in particular is directly related to the heating and disruption of cold gas by massive young stars, whereas the N2H+ better samples gas not yet affected by this process. We therefore suggest that the HCO+-N2H+-Brγ relationship is a useful diagnostic of a molecular clump's progress in forming massive stars.

description: We compiled a sample of 60 quasars with spectroscopy on at least six epochs from the Sloan Digital Sky Survey (SDSS) to study the variabilities of the spectral shape, the continuum and the emission lines luminosity. In this paper, we present the results of SDSS J030639.57+000343.1. We found a strong anti-correlation between the continuum luminosity at $5100 Å$ and the spectral index, implying a bluer-when-brighter trend. The luminosity of the broad $\rm H_α$ line is proportion to the continuum luminosity at $5100 Å$. Correspondingly, we did not find strong correlation between the equivalent width of broad $\rm Hα$ and the continuum luminosity, i.e. no baldwin effect of broad $\rm Hα$ in this source.

description: Mitotic activity is a crucial proliferation biomarker for the diagnosis and prognosis of different types of cancers. Nevertheless, mitosis counting is a cumbersome process for pathologists, prone to low reproducibility, due to the large size of augmented biopsy slides, the low density of mitotic cells, and pattern heterogeneity. To improve reproducibility, deep learning methods have been proposed in the last years using convolutional neural networks. However, these methods have been hindered by the process of data labelling, which usually solely consist of the mitosis centroids. Therefore, current literature proposes complex algorithms with multiple stages to refine the labels at pixel level, and to reduce the number of false positives. In this work, we propose to avoid complex scenarios, and we perform the localization task in a weakly supervised manner, using only image-level labels on patches. The results obtained on the publicly available TUPAC16 dataset are competitive with state-of-the-art methods, using only one training phase. Our method achieves an F1-score of 0.729 and challenges the efficiency of previous methods, which required multiple stages and strong mitosis location information.

title: Trace amine-associated receptor 1 as a novel immunomodulatory target in multiple sclerosis
Creators: name: Barnes, David A.
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: TAAR1 is a previously established neuroregulator with emerging evidence suggesting a role in modulation of the immune response. Multiple sclerosis is an immune-mediated demyelinating disease of the central nervous system (CNS). This study investigated expression of TAAR1 in immune cells relevant to MS pathophysiology in both the periphery and CNS of MS patients. RT-qPCR analyses of TAAR1 mRNA levels in peripheral immune cells from MS patients shared a statistically significant decrease in TAAR1 mRNA in MS patient monocytes compared to controls. TAAR1 expression at the protein-level was visualized in both peripherally-derived and CNS-resident macrophages bordering an MS lesion. Additionally, this study attempted to characterize a function of TAAR1 within the immune system that is relevant to MS neuroinflammation. Effects of TAAR1 agonist treatment on cytokine secretion and on the metabolic profile of pro-inflammatory macrophages from the periphery indicated a potential anti-inflammatory function, however, TAAR1 agonists had no effect on cytokine secretion from macrophages resident to the CNS. This study effectively demonstrates the potential for a novel link between TAAR1 and MS pathophysiology and establishes critical preliminary research towards elucidating the function of TAAR1 in peripheral and CNS-resident macrophages.

description: The physics of collisionless shocks is a very broad topic which has been studied for more than five decades. However, there are a number of important issues which remain unresolved. The energy repartition amongst particle populations in quasiperpendicular shocks is a multi-scale process related to the spatial and temporal structure of the electromagnetic fields within the shock layer. The most important processes take place in the close vicinity of the major magnetic transition or ramp region. The distribution of electromagnetic fields in this region determines the characteristics of ion reflection and thus defines the conditions for ion heating and energy dissipation for supercritical shocks and also the region where an important part of electron heating takes place. All of these processes are crucially dependent upon the characteristic spatial scales of the ramp and foot region provided that the shock is stationary. The earliest studies of collisionless shocks identified nonlinearity, dissipation, and dispersion as the processes that arrest the steepening of the shock transition. Their relative role determines the scales of electric and magnetic fields, and so control the characteristics of processes such as of ion reflection, electron heating and particle acceleration. The purpose of this review is to address a subset of unresolved problems in collisionless shock physics from experimental point of view making use multi-point observations onboard Cluster satellites. The problems we address are determination of scales of fields and of a scale of electron heating, identification of energy source of precursor wave train, an estimate of the role of anomalous resistivity in energy dissipation process by means of measuring short scale wave fields, and direct observation of reformation process during one single shock front crossing.

Towards Integrated Acoustic Models for Speech Synthesis

Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: subject: 80107 Natural Language Processing
subject: FOS: Computer and information sciences

description: All Statistical Parametric Speech Synthesizers consist of a linear pipeline of components. This view means that the synthesizer consists of a top-down structure where data fed into the synthesizer goes to front-end, then to the prediction algorithm, then to the waveform generation, and so on until the speech is finally constructed. Each component in this pipeline naïvely receives a stream of numbers from the preceding component, and spits out a stream of numbers for the next one in line, with little to no knowledge of what happens in the larger scheme of the pipeline. In this thesis, I argue against this “Markovian” structure, and instead propose the idea of an Integrated structure. In an integrated structure, every component in the system influences, and is in turn influenced by every other component in the system. This thesis describes four sets of experiments that move towards this idea. The first involves using lexical information to improve waveform generation algorithms. The second tries to increase the interaction between prediction algorithms and waveform generation. The third is an attempt to derive phonemes and phonetic information automatically from the speech rather than from the text. The last, and probably hardest, describes an idea for an evaluation metric that pays attention to multiple components of the synthesizer, rather than focusing on just a single one.

description: Statistical analyses of the measurements of the Hubble-Lemaître constant $H_0$ (163 measurements between 1976 and 2019) show that the statistical error bars associated with the observed parameter measurements have been underestimated -- or the systematic errors were not properly taken into account -- in at least 15-20\% of the measurements. The fact that the underestimation of error bars for $H_0$ is so common might explain the apparent discrepancy of values, which is formally known today as the Hubble tension. Here we have carried out a recalibration of the probabilities with this sample of measurements. We find that $xσ$ deviation is indeed equivalent in a normal distribution to $x_{\rm eq.}σ$s deviation in the frequency of values, where $x_{\rm eq.}=0.83x^{0.62}$. Hence, a tension of 4.4$σ$, estimated between the local Cepheid-supernova distance ladder and cosmic microwave background (CMB) data, is indeed a 2.1$σ$ tension in equivalent terms of a normal distribution of frequencies, with an associated probability $P(>x_{\rm eq.})=0.036$ (1 in 28). This can be increased up to a equivalent tension of 2.5$σ$ in the worst of the cases of claimed 6$σ$ tension, which may anyway happen as a random statistical fluctuation.

description: We present the latest and final version of the movie of the SiO masers toward the Mira variable TX Cam. The new version consists of 112 frames (78 successfully reduced epochs) with data covering almost three complete stellar cycles between 24 May 1997 to 25 January 2002, observed with the VLBA. In this paper we examine the global morphology, kinematics and variability of the masering zone. The morphology of the emission is confined in a structure that usually resembles a ring or an ellipse, with occasional deviations due to localised phenomena. The ring appears to be contracting and expanding, although for the first cycle contraction is not observed. The width and outer boundary of the masering zone follow the stellar pulsation. Our data seem to be consistent with a shock being created once per stellar cycle at maximum that propagates with a velocity of ~7 km/s. The difference in velocities along different axes strongly suggests that the outflow in TX Cam is bipolar. The contribution of projection is examined and our results are compared with the latest theoretical model.

description: Opinion dynamics concerns social processes through which populations or groups of individuals agree or disagree on specific issues. As such, modelling opinion dynamics represents an important research area that has been progressively acquiring relevance in many different domains. Existing approaches have mostly represented opinions through discrete binary or continuous variables by exploring a whole panoply of cases: e.g. independence, noise, external effects, multiple issues. In most of these cases the crucial ingredient is an attractive dynamics through which similar or similar enough agents get closer. Only rarely the possibility of explicit disagreement has been taken into account (i.e., the possibility for a repulsive interaction among individuals' opinions), and mostly for discrete or 1-dimensional opinions, through the introduction of additional model parameters. Here we introduce a new model of opinion formation, which focuses on the interplay between the possibility of explicit disagreement, modulated in a self-consistent way by the existing opinions' overlaps between the interacting individuals, and the effect of external information on the system. Opinions are modelled as a vector of continuous variables related to multiple possible choices for an issue. Information can be modulated to account for promoting multiple possible choices. Numerical results show that extreme information results in segregation and has a limited effect on the population, while milder messages have better success and a cohesion effect. Additionally, the initial condition plays an important role, with the population forming one or multiple clusters based on the initial average similarity between individuals, with a transition point depending on the number of opinion choices.

title: Design of a novel biologically inspired robot fish with low cost
Creators: name: Jian, Xinyu

description: Being a novel form of underwater vehicle, the robot fish has the advantages of good maneuverability, quick response, high propulsion efficiency, and low noise. It is widely used in marine biological observation, marine water quality monitoring, submarine pipeline inspection, and exploration. It is one of the hot research topics in the marine field. Compared to the robot fish propulsion mechanism using rigid components, which has problems of no adaptability to underwater motion, and low motion efficiency and inability to imitate the fish body to perform flexible swings, the soft robot fish has higher swimming efficiency, and is the focus of this project. In this work, the design of a novel soft robot fish, with focus on actuation system design, is proposed. The actuation system is based on the motor-driven bevel gear mechanism, which has the advantages of realizing rapid speed regulation, two-way drive, and adjustment range in a small space. One advantage of our design is its straightforward assembly and relatively simple fabrication, which can be completed mainly using 3D printing technology. Three different designs are proposed, based on a comprehensive comparison in terms of efficiency, reliability, and fabrication cost, one design is chosen to be fabricated and tested. The test focuses on the relationship between the swing amplitude, frequency, and swimming speed of the tail. The experiment is mainly divided into two parts: the test of driving the tail of the propulsion mechanism; and the robot fish underwater movement. The test results show that the design achieves the expected motion goal and is engineering feasible, which provides a new solution for the design of the robot fish.

description: The field of the new media encounter is a narrative of long duration in the context of modernization and progress discourses, which starts in classical antiquity with Plato's myth of Theuth (Plat.Prot.) and is continued until today, e.g. in Lévi-Strauss' Tristes Tropiques (A World on the Wane). In the Digital Classics which constitute a new field in this encounter we can see the possibilities of the multi-dimensionality - here the conditions of order and arrangement of texts are discussed, but also the change in forms of representation. The position of the project eAQUA within the discussion of digital media is analyzed and some of the
perspectives are discussed which have emerged from the project work: cooccurrence search, the systematization of chance (serendipity), rare incidents and new ways of contextualizing the chronological and spatial visualization.

description: The web contains a tremendous number of data sets presented visually, which computers cannot currently read. Most people, however, understand the data sets with little difficulty, suggesting the potential for applying the techniques of crowd-sourcing to the problem of understanding web data sets. In this thesis we study several issues with respect to crowd-sourcing a collection of wrappers, or small programs mapping data sets to their logical structure, from a crowd of end users. We pay special attention to the majority of users who are not programmers. We present a prototype system, Mixer, that allows end users to demonstrate and execute repetitive ad hoc data retrieval actions over multiple data sources. The evaluation of the prototype suggests that end users, under the strong assumption that input to the individual query systems, as well as their output, is fully understood, are able to construct and combine data from multiple data sources. Furthermore we present another prototype system, SmartWrap showing that end users, explicitly including non programmers, can demonstrate actions sufficient to construct for a data set a wrapper, i.e. the instructions needed to understand the data set. A pilot crowd is able to construct wrappers for most requested data sets, but gives no guidance that the wrapped data sets are useful or relevant to anyone. To narrow the search for relevant data sets we turn to an audience that theory predicts will make use of additional structure in web pages: blind people. We present the theory and the results of a preliminary study demonstrating the concrete benefits non visual users of the web stand to gain from increased structure in web pages and more specifically from the introduction of web tables in place of template-driven visual data sets.

description: I review what eLISA will see from Galactic binaries -- double stars with orbital periods less than a few hours and white dwarf (or neutron star/black hole) components. I discuss the currently known binaries that are guaranteed (or verification) sources and explain why the expected total number of eLISA Galactic binaries is several thousand, even though there are large uncertainties in our knowledge of this population, in particular that of the interacting AM CVn systems. I very briefly sketch the astrophysical questions that can be addressed once these thousands of systems are detected. I close with a short outline of the electro-magnetic facilities that will come on line before eLISA will fly and the importance of developing analysis plans using both electro-magnetic and gravitational wave data.

description: Differential operators usually result in derivatives expressed as a ratio of differentials. For all but the simplest derivatives, these ratios are typically not algebraically manipulable, but must be held together as a unit in order to prevent contradictions. However, this is primarily a notational and conceptual problem. The work of Abraham Robinson has shown that there is nothing contradictory about the concept of an infinitesimal differential operating in isolation. In order to make this system extend to all of calculus, however, some tweaks to standard calculus notation are required. Understanding differentials in this way actually provides a more straightforward understanding of all of calculus for students, and minimizes the number of specialized theorems students need to remember, since all terms can be freely manipulated algebraically.

description: After four years of work, the results of the working group mobility are presented as ethnological case study for interdisciplinary cooperation. Important steps are described chronologically by referring to protocols, summaries of plenary sessions and discussions about literature. By doing so, one can follow how this group analysed notions of mobility and the current state of research on mobility. Using the concepts of social world, arenas, boundary objects, and conventions supported the critical review of this negotiation process. Conclusively,
characteristics of the interdisciplinary group such as personal background, expectations and goals shaped how mobility was commonly understood at the end.

description: Let $F$ be Cayley's ruled cubic surface in a projective three-space over any commutative field $K$. We determine all collineations fixing $F$, as a set, and all cubic forms defining $F$. For both problems the cases $|K|=2,3$ turn out to be exceptional. On the other hand, if $|K|\geq 4$ then the set of simple points of $F$ can be endowed with a non-symmetric distance function. We describe the corresponding circles, and we establish that each isometry extends to a unique projective collineation of the ambient space.
