description: The goal of argumentation mining, an evolving research field in computational linguistics, is to design methods capable of analyzing people's argumentation. In this article, we go beyond the state of the art in several ways. (i) We deal with actual Web data and take up the challenges given by the variety of registers, multiple domains, and unrestricted noisy user-generated Web discourse. (ii) We bridge the gap between normative argumentation theories and argumentation phenomena encountered in actual data by adapting an argumentation model tested in an extensive annotation study. (iii) We create a new gold standard corpus (90k tokens in 340 documents) and experiment with several machine learning methods to identify argument components. We offer the data, source codes, and annotation guidelines to the community under free licenses. Our findings show that argumentation mining in user-generated Web discourse is a feasible but challenging task.

description: We report the observation of a new superfluid phase of 3He -- polar phase. This phase appears in 3He confined in a new type of aerogel with nearly parallel arrangement of strands which play a role of ordered impurities. Our observations qualitatively agree with theoretical predictions and suggest that in other systems with unconventional Cooper pairing (e.g. in unconventional superconductors) similar phenomena may be found in presence of anisotropic impurities.

description: This study aims to discover if and how archivists promote their analog film collections through outreach events. The researcher also wanted to learn how archivists felt about analog film in the digital age. The study utilized a survey sent out through the Association of Moving Image Archivists email listserv; a post-survey was sent out to willing participants to help draw final conclusions. The survey showed that outreach activities are occurring, and analog film is still valuable to archivists but as many studies show, resources and challenges limit the amount that can be done. The study supported the tension between digital files and analog film, and future trends will determine if analog film continues to be promoted for future generations.

description: In its early stages, the field of data visualization focused on representing data, which, though it had physical characteristics, was difficult if not impossible to see.  From internal medicine to the ends of our reach into space, tools like magnetic resonance imagers and high-powered telescopes have collected, colored, and differentiated data for us.  Those tools have changed the way we work with all kinds of data.  But abstract ideas, by their nature, do not have physical attributes, so it is difficult to know where to begin to create representations of things like document structure.  This project explores options for providing document visualizations to assist authors and information architects in analyzing their document collections.  Though conduct of a user study falls outside the scope of this project, this paper also outlines a proposed method for evaluating the prototype.

description: Isothermal crystallization of the mono-hydroxyl alcohol n-butanol was studied with dielectric spectroscopy in real time. The crystallization was carried out using two different sample cells at 15 temperatures between 120 K and 134 K. For all temperatures, a shift in relaxation times to shorter times was observed during the crystallization process, which is characterized by a drop in relaxation strength. The two different sample environments induced quite different crystallization behaviors, consistent and reproducible over all studied temperatures. An explanation for the difference was proposed on the background of an Avrami and a Maxwell-Wagner analysis. Both types analysis suggest that the morphology of the crystal growth changes at a point during the crystallization. The differences between the cells can be explained by this transition taking place at different times for the two cells.

description: Radio-loud active galactic nuclei are among the most powerful objects in the universe. In these objects, most of the emission comes from relativistic jets getting their power from the accretion of matter onto supermassive black holes. However, despite the number of studies, a jet's acceleration to relativistic speeds is still poorly understood. It is widely known that jets contain relativistic particles that emit radiation through several physical processes, one of them being the inverse Compton scattering of photons coming from external sources. In the case of a plasma composed of electrons and positrons continuously heated by the turbulence, inverse Compton scattering can lead to relativistic bulk motions through the Compton rocket effect. We investigate this process and compute the resulting bulk Lorentz factor in the complex photon field of an AGN composed of several external photon sources. We consider various sources here: the accretion disk, the dusty torus, and the broad line region. We take their geometry and anisotropy carefully into account in order to numerically compute the bulk Lorentz factor of the jet at every altitude. The study, made for a broad range of parameters, shows interesting and unexpected behaviors of the bulk Lorentz factor, exhibiting acceleration and deceleration zones in the jet. We investigate the patterns of the bulk Lorentz factor along the jet depending on the source sizes and on the observation angle and we finally show that these patterns can induce variability in the AGN emission with timescales going from hours to months.

description: Case investigation and contact tracing (CICT) has been a fundamental public health practice during the COVID-19 pandemic, but little causal evidence exists on its effectiveness. In partnership with the Santa Clara County Public Health Department, this study utilizes a stepped-wedge (randomized rollout) trial to assess the impacts of call-based contact tracing, compared to an automated virtual survey. We focus on the effects on disease transmission, resource linkage, and other meaningful individual and broader public health outcomes.

description: The sealing potential of geological formations (“cap rocks”) plays an important role in long-term industry projects associated with mine water rebound, carbon sequestration and nuclear waste disposal. It is an important criterion in risk management and monitoring concepts. Clay content and mineralogy were used as screening parameters in order to estimate permeability in the Upper Cretaceous Emscher Formation. The Emscher Formation consists of monotonous grey to greenish alternating clay-, silt- and marlstones with a high amount of micrite. Distribution of clays was quantified on core and cuttings material using combined X-ray diffraction and Rietveld refinement. An important task was to evaluate content and changes in clay mineralogy with respect to expandable clays. The aim is to assess its self-sealing potential. Core sections and cuttings were retrieved from groundwater monitoring wells drilled in the northern part of the Ruhr District. The aim of these wells is to record hydraulic potential in the overburden section during mine water rebound in the Ruhr District. Classical lithological and sedimentological analyses of core section were conducted. Bulk geochemistry included total inorganic and organic carbon measurements. Elemental analyses on selected samples was determined using X-ray fluorescence spectroscopy. Clay mineral identification and quantification was performed on (a) bulk rock, (b) <2µm random powder and (c) <2µm oriented samples. For expandable clays, ethylene glycol and heating to 550°C was applied.

description: There is a distinct lack of current and specific guidance on the creation of content for social media in cultural heritage institutions. This study aims to remedy that lack of specificity by examining user responses to social media strategies employed by cultural heritage institutions and in so doing, identify and evaluate emerging trends in social media content generation. In order to accomplish this task, the researcher conducted an analysis of the British Museum's Facebook page. This consisted of evaluating posts according to a coding schema and recording the level of user response to each post. This method allowed the researcher to identify past, present, and emerging trends as well as the efficacy of each trend in terms of user interaction.

description: Pure and pristine Archaean and Palaeoproterozoic banded iron formations (BIFs) are excellent marine geochemical archives, especially of original rare earths and yttrium (REY) characteristics. As recently demonstrated for the Mt.Ruker BIF in Antarctica[1], ultrapure BIFs preserve seawater-like REY distribution with heavy REYSN enrichment and light REYSN depletion (SN: shale-normalized). Our results indicate that a prominent feature of the REY signature of seawater throughout Earth’s history has been a super-chondritic Y/Ho ratio which falls between that of potential detritus and the maximum Y/Ho ratio of modern seawater. Another more subtle and fragile proxy of modern seawater is the W-type lanthanide tetrad effect (LTE) which results from the slightly differing bonding characteristics of individual REY in chemical complexes, due to the specific electron configuration of the REY3+ ions. This W-type LTE is found in pure marine carbonate rocks and in BIFs, and confirms the primary and marine origin of their REY distribution. The preservation of uniform, super-chondritic Y/Ho ratios in combination with the W-type LTE in chert and Fe-oxide BIF bands is an excellent tool to test the pristineness of geochemical signals in such samples as well as evidence for the primary origin of banding in BIFs.

description: Sustainable groundwater use is commonly linked to groundwater recharge: If the long-term average of withdrawals is not higher than the inflows, the groundwater use is considered sustainable. In arid environments, natural inflows are small, but the amount of groundwater-in-storage might be large. Potential groundwater withdrawals cannot be referred to the small inflows only. Hence, the determination of groundwater-in-storage volumes and their exploitable parts, respectively, is of high importance. In this study regional aquifer systems, like they exist on the Arabian Peninsula or in North Africa, are considered. Options and limits in the determination of groundwater-in-storage are investigated. For the assessment of groundwater-in-storage the determination of aquifer geometry and storativity (under confined and unconfined conditions) are essential. Exploration, data interpretation, and knowledge of aquifer genesis allow for accurate determination of aquifer geometry. In contrast, determination of storage coefficients is difficult. Firstly, the logarithmic relation between storativity and drawdown makes determination from pumping tests indifferent. In regional aquifer systems, exploitable groundwater volumes relate to confined conditions, where the uncertainty of the storage coefficient may range over an order of magnitude. Secondly, there is also a lack in data interpretation: known heterogeneities in lithology, or assumable changes with increasing aquifer depth are rarely translated into corresponding distributions of storage coefficients. Herewith, we want to emphasize the importance of the assessment of groundwater-in-storage and the related storage coefficients. Increasing occurrence of dry seasons lead to use of groundwater-in-storage in humid environments, too. Consideration of groundwater-in-storage is hence important for both arid and humid environments.

description: In this paper we address the problem of testing whether two observed trees $(t,t')$ are sampled either independently or from a joint distribution under which they are correlated. This problem, which we refer to as correlation detection in trees, plays a key role in the study of graph alignment for two correlated random graphs. Motivated by graph alignment, we investigate the conditions of existence of one-sided tests, i.e. tests which have vanishing type I error and non-vanishing power in the limit of large tree depth. For the correlated Galton-Watson model with Poisson offspring of mean $λ>0$ and correlation parameter $s \in (0,1)$, we identify a phase transition in the limit of large degrees at $s = \sqrtα$, where $α\sim 0.3383$ is Otter's constant. Namely, we prove that no such test exists for $s \leq \sqrtα$, and that such a test exists whenever $s > \sqrtα$, for $λ$ large enough. This result sheds new light on the graph alignment problem in the sparse regime (with $O(1)$ average node degrees) and on the performance of the MPAlign method studied in Ganassali et al. (2021), Piccioli et al. (2021), proving in particular the conjecture of Piccioli et al. (2021) that MPAlign succeeds in the partial recovery task for correlation parameter $s>\sqrtα$ provided the average node degree $λ$ is large enough. As a byproduct, we identify a new family of orthogonal polynomials for the Poisson-Galton-Watson measure which enjoy remarkable properties. These polynomials may be of independent interest for a variety of problems involving graphs, trees or branching processes, beyond the scope of graph alignment.

description: Ultramafic-hosted mineralized systems commonly form massive sulphides at the seafloor which are enriched in base (Cu, Zn, Ni), critical (Co) and precious (Au, Ag) metals. In present-day settings, the limited conditions of observation at the seafloor prevents a complete understanding of these hydrothermal systems, especially concerning deep hydrothermal processes. A way to unravel deep hydrothermal processes that occur in these systems is to focus on fossil analogues preserved on-land which noticeably well crop out in mountain belts. We adopted this strategy here and focused on a mineralized system preserved in the Platta nappe (SE Switzerland), a remnant of the Jurassic opening of the Alpine Tethys Ocean. The geometry and petrographic assemblages of the hydrothermal system, previously established, served as a base for the present study. We performed a geochemical tracing both on whole rocks and in-situ metal-bearing phases (sulphides and oxides) sampled at three distinct structural positions of the hydrothermal system. Among the geochemical tracers, Co, Ni and Se appear as good proxies to constrain hydrothermal processes. Indeed, at given structural position, the Co/Ni ratio increases in the most mineralized and altered sample suggesting this ratio is linked to the intensity of hydrothermal alteration. Also, towards the top of the system, a general trend showing respective decrease and increase of the Co/Ni ratio and of the Se content in metal-bearing phases was observed. The evolution of these geochemical tracers together with petrographic evidences supports a genetic model for the Marmorera-Cotschen hydrothermal system involving hydrothermal fluid progressively mixing with seawater.

description: COELIOXYS (PLATYCOELIOXYS) MITCHELL, 1973
Type species: Coelioxys alatiformis Friese, 1921.
Diagnosis: This monotypic subgenus can be distinguished from all other Coelioxys subgenera by the shape of S 5 in females, which is spatulate and greatly expanded towards the apex, its margins somewhat swollen and shining, and ventral surface convex (Fig. 44), and by the postgradular areas of T 2 – T 3 in males that are foveate in a manner not found in other subgenera (Fig. 45): on T 2, the fovea is elliptical and covered with minute whitish hairs, whereas in T 3 it is smaller and circular (Fig. 45). In females from other subgenera the S5 is elongate towards apex, never spatulate nor greatly expanded, except in C. (Paracoelioxys) alata, in which the S5 margins are greatly expanded but straight, never swollen, as in C. alatiformis (Fig. 44); the ventral surface of S5 is concave and the apex is broad and truncate, in contrast to the convex surface and ellipsoid apex in C. alatiformis. The fovea on the postgradular area of T 2 of males from other subgenera is never elliptical, hairy and deep, but slender as in C. conoidea (Fig. 90), C. rufescens, C. (Paracoelioxys) (Fig. 88), and C. (Boreocoelioxys) (Fig. 27); minute and circular, as in C. (Glyptocoelioxys) (Fig. 78), except C. chilensis [see Discussion of C. (Glyptocoelioxys)], and circular and bare, as in C. reginae, C. albolineata, and C. confusa.
Comments: This subgenus comprises only one species, C. alatiformis, which ranges from Mexico to Argentina (Rocha-Filho & Packer, 2015).

description: Fiscal tools—taxes and/or subsidies—are increasingly used to address diet-related health problems. However, some studies have found that these tools are markedly more effective if attention is draw to the tax or subsidy, suggesting that the price change alone may go unnoticed in the complex food environments that consumers face. Interventions that prompt individuals to consider health during choice show promise for promoting healthy food choices in both simple laboratory settings and complex, real-world markets. In this pre-registered study, I examine the impact of dietary fiber health prompts and/or dietary fiber subsidies on the per-serving fiber content of foods chosen, the documented set of products considered, and (self-reported) nutrition information use by participants in an online supermarket setting. Participants were randomized to one of four conditions: 1) control, 2) subsidy, 3) fiber prompt, and 4) fiber prompt + subsidy. Results show that both the prompt and prompt + subsidy conditions significantly increase fiber content of foods chosen (with the latter having a larger effect). While all three interventions influence the probability of using nutrition information during food choice and affect the set of products that respondents consider relative to the control condition, the effects were larger for the prompt and prompt + subsidy conditions. A multiple mediation analysis illustrates that both direct and indirect (through the set of products considered and the use of fiber information during choice) pathways lead to the significant overall increase in fiber content of selected foods.

description: We study radial particle transport in stellarator plasmas using cryogenic pellet injection. By means of perturbative experiments, we estimate the experimental particle flux and compare it with neoclassical simulations. Experimental evidence is obtained of the fact that core depletion in helical devices can be slowed-down even by pellets that do not reach the core region. This phenomenon is well captured by neoclassical predictions with DKES and FORTEC-3D.

description: We investigate a small-scale ($\approx$ 1.5 Mm along the slit), supersonic downflow of about 90 km s$^{-1}$ in the transition region above the light-bridged sunspot umbra in AR 11836. The observations were obtained with the Interface Region Spectrograph (IRIS) on 2013 September 2, from 16:40 to 17:59 UT. The downflow shows up as red-shifted "satellite" lines of the Si IV and O IV transition region lines and is remarkably steady over the observing period of nearly 80 min. The downflow is not visible in the chromospheric lines, which only show an intensity enhancement at the location of the downflow. The density inferred from the line ratio of the red-shifted satellites of the O IV lines ($N_\mathrm{e} = 10^{10.6\pm0.25} \mathrm{cm}^{-3}$) is only a factor 2 smaller than the one inferred from the main components ($N_\mathrm{e} = 10^{10.95\pm0.20} \mathrm{cm}^{-3}$). Consequently, this implies a substantial mass flux ($\approx 5 \times 10^{-7}$ g cm$^{-2}$ s$^{-1}$), which would evacuate the overlying corona on time scales of the order of 10 s. We interpret these findings as evidence of a stationary termination shock of a supersonic siphon flow in a cool loop rooted in the central umbra of the spot.

description: Im Rahmen dieser Masterarbeit wird anhand einer empirischen Erhebung untersucht, ob ein nachvollziehbarer Zusammenhang zwischen dem medialen Habitus und der Technologieakzeptanz festgestellt werden kann. Die Untersuchung, findet in einer sozialen Organisation statt. Es werden dabei qualitative Interviews mit fünf Führungskräften dieser Organisation durchgeführt, welche als Datengrundlage zur Bestimmung des medialen Habitus dienen. Anschließend erfolgt die Bestimmung der Technologieakzeptanz anhand eines Fragebogens, der von den Studienteilnehmer*innen beantwortet wird. Die Auswertung der Studie zeigte, dass anhand der erhobenen Daten keine eindeutige Antwort auf die Forschungsfrage gegeben werden kann. Ein Zusammenhang der beiden Kernkonzepte der Arbeit wird in einigen Interviews klar ersichtlich, widerspricht sich in anderen Interviews dann aber wieder. Weitere Forschungen, mit einer höheren Anzahl von Teilnehmer*innen, könnten für mehr Klarheit sorgen.

description: In the first order formalism of gravity theories, there are some theories which are not Lorentz-diffeomorphism covariant. In the framework of such theories we cannot apply the method of conserved charge calculation used in Lorentz-diffeomorphism covariant theories. In this paper we firstly introduce the total variation of a quantity due to an infinitesimal Lorentz-diffeomorphism transformation. Secondly, in order to obtain the conserved charges of Lorentz-diffeomorphism non-covariant theories, we extend the Tachikawa method \cite{3}. This extension includes not only Lorentz gauge transformation but also the diffeomorphism. We apply this method to the Chern-Simons-like theories of gravity (CSLTG) and obtain a general formula for the entropy of black holes in those theories. Finally, some examples on CSLTG are provided and the entropy of the BTZ black hole is calculated in the context of the examples.

description: This paper describes the application of a part-of-speech tagger to a particular configuration of historical German documents. Most natural language processing (NLP) is done on contemporary documents, and historical documents can present difficulties for these tools. I compared the performance of a single high-quality tagger on two stages of historical German (Early Modern German) materials. I used the TnT (Trigrams 'n' Tags) tagger, a probabilistic tagger developed by Thorsten Brants in a 2000 paper. I applied this tagger to two subcorpora which I derived from the University of Manchester's GerManC corpus, divided by date of creation of the original document, with each one used for both training and testing.  I found that the earlier half, from a period with greater variability in the language, was significantly more difficult to tag correctly. The broader tag categories of punctuation and "other" were overrepresented in the errors.

description: A linear vector equation in two unknown vectors is examined in the framework of tropical algebra dealing with the theory and applications of semirings and semifields with idempotent addition. We consider a two-sided equation where each side is a tropical product of a given matrix by one of the unknown vectors. We use a matrix sparsification technique to reduce the equation to a set of vector inequalities that involve row-monomial matrices obtained from the given matrices. An existence condition of solutions for the inequalities is established, and a direct representation of the solutions is derived in a compact vector form. To illustrate the proposed approach and to compare the obtained result with that of an existing solution procedure, we apply our solution technique to handle two-sided equations known in the literature. Finally, a computational scheme based on the approach to derive all solutions of the two-sided equation is discussed.

description: In this paper, we study the leader-following consensus problem for a class of uncertain nonlinear multi-agent systems under jointly connected directed switching networks. The uncertainty includes constant unbounded parameters and external disturbances. We first extend the recent result on the adaptive distributed observer from global asymptotical convergence to global exponential convergence. Then, by integrating the conventional adaptive control technique with the adaptive distributed observer, we present our solution by a distributed adaptive state feedback control law. Our result is illustrated by the leader-following consensus problem for a group of van der Pol oscillators.
description: 21 pages, 5 figures. In this replacement version, the higher-order case is considered instead of the second-order case. Also, the main difference of this version from the reference [16] is that Appendix B is added to show the existence of the limit of the function V(t) defined in the equation (33) as t tends to infinity
CAPSID: A Private Session ID System for Small UAVs

Subjects: subject: Computer security

description: The US Federal Aviation Administration (FAA) has recently mandated that small unmanned aerial vehicles (UAVs) be equipped with a transmitter that broadcasts the UAV's serial number, location, and altitude. The inclusion of a unique identifier in the form of a UAV serial number has stoked fears that the identifier will be used to track UAV operators and has even led some UAV operators to file a lawsuit against the FAA.In this paper, we propose CAPSID, an implementation of the FAA session ID concept that provides message authentication—something current Remote ID implementations lack—and strong operator anonymity. The FAA (or its equivalent in other jurisdictions) retains the ability to de-anonymize operators, but only in circumstances prescribed by law. To make this possible, CAPSID introduces a partially trusted third party, the Custodian, that serves as the bridge between anonymous identifiers and true operator identity. The Custodian ensures that the legal requirements for de-anonymization are met, preventing unnecessary mass collection of personally identifying information by a government agency.We formally verify the message authentication property of CAPSID using a cryptographic protocol checker and provide a formal proof of identifier non-linkability, even in the presence of corrupt (but non-colluding) authorities.
Quantum Simulation of a Topological Mott Insulator with Rydberg Atoms in a Lieb Lattice

description: We propose a realistic scheme to quantum simulate the so-far experimentally unobserved topological Mott insulator phase -- an interaction-driven topological insulator -- using cold atoms in an optical Lieb lattice. To this end, we study a system of spinless fermions in a Lieb lattice, exhibiting repulsive nearest and next-to-nearest neighbor interactions, and derive the associated zero temperature phase diagram within mean-field approximation. In particular, we analyze how the interactions can dynamically generate a charge density wave ordered, a nematic as well as a topologically non-trivial quantum anomalous Hall phase. We characterize the topology of the different phases by the Chern number and discuss the possibility of phase coexistence. Based on the identified phases, we propose a realistic implementation of this model using cold Rydberg-dressed atoms in an optical lattice. The scheme, which allows one to access in particular the topological Mott insulator phase, robustly and independently of its exact position in parameter space, merely requires global, always-on off-resonant laser coupling to Rydberg states and is feasible with state-of-the-art experimental techniques.

description: This paper presents the results of a usability study comparing online video tutorials and online slide show tutorials. This study focused on four basic instructional library tutorials: How to Request a Book from the Library Service Center, How to Recall a Book that is Checked out, How to Create a Document Delivery Account, and How to create a Refworks Account. Patrons were randomly shown two tutorials in video format and two tutorials in slide show format. The goal of this study was to determine whether patrons preferred viewing these tutorials in the video format or in the slide show format. The patrons' ability to complete the specified task after watching the two types of tutorials was also measured. Results of this study identify areas where the online tutorials could be improved and suggest recommendations for changes.

description: By looking at the development process of the Digital Public Library of America, this paper explores relevant takeaways for innovation within public libraries. The extensive open planning process, public input, and early success of the project has many implications for public libraries, and new models of service in digital spaces. I also briefly consider the implications of startups, and how a public testing model can be adapted for use within public libraries. Through preliminary analysis of the DPLA, the private sector, and current public library projects, strategies are identified that can be applied widely across the profession.

description: The concept of a circular economy has arisen in response to the problems related to the limits of the dominant linear economic system in contemporary societies and of the finite resources of our planet. The transition from waste status to a raw material by reusing it makes it possible to modify its value for future users and thus to redistribute this value. This article focuses on the case of spent grain to illustrate the role of the circular economy in food transition. Bases on a series of interviews, the paper discusses business modeling to operationalize sustainable development in the food sector and presents a discussion and conclusion on the advantages and limitations of the deployment of the circular economy in the brewing industry, taking into account and understanding the interests and constraints of various stakeholders.
Scalar field correlator in de Sitter space at next-to-leading order in a 1/N expansion

description: We study the dynamics of light quantum scalar fields in de Sitter space on superhorizon scales. We compute the self-energy of an O(N) symmetric theory at next-to-leading order in a 1/N expansion in the regime of superhorizon momenta, and we obtain an exact analytical solution of the corresponding Dyson-Schwinger equations for the two-point correlator. This amounts to resumming the infinite series of nonlocal self-energy insertions, which typically generate spurious infrared and/or secular divergences. The potentially large de Sitter logarithms resum into well-behaved power laws from which we extract the field strength and mass renormalization. The nonperturbative 1/N expansion allows us to discuss the case of vanishing and negative tree-level square mass, which both correspond to strongly coupled effective theories in the infrared.

description: This project involves comparing two relational database servers using sections of the AS3AP industry standard benchmark. The two servers tested were Oracle 8.0.3, developed by the Oracle Corporation and MySQL 3.22.14b-gamma, developed by T.c.X DataKonsultAB. The servers were both installed on the same Intel-based hardware platform running the Red Hat Linux 5.2 operating system (kernel 2.0.36). All tests were conducted over a network on a fixed size database. The complexities of the queries were varied and the transactions per second were measured on the database server side to give an indication of relative performance.
