description: The aim of this paper is to extend our knowledge about the power-law relationship between citation-based performance and collaboration patterns for papers of the Natural Sciences domain. We analyzed 829,924 articles that received 16,490,346 citations. The number of articles published through collaboration account for 89%. The citation-based performance and collaboration patterns exhibit a power-law correlation with a scaling exponent of 1.20, SD=0.07. We found that the Matthew effect is stronger for collaborated papers than for single-authored. This means that the citations to a field research areas articles increase 2.30 times each time it doubles the number of collaborative papers. The scaling exponent for the power-law relationship for single-authored papers was 0.85, SD=0.11. The citations to a field research area single-authored articles increase 1.89 times each time the research area doubles the number of non-collaborative papers.

description: Deriving robust control policies for realistic urban navigation scenarios is not a trivial task. In an end-to-end approach, these policies must map high-dimensional images from the vehicle's cameras to low-level actions such as steering and throttle. While pure Reinforcement Learning (RL) approaches are based exclusively on engineered rewards, Generative Adversarial Imitation Learning (GAIL) agents learn from expert demonstrations while interacting with the environment, which favors GAIL on tasks for which a reward signal is difficult to derive, such as autonomous driving. However, training deep networks directly from raw images on RL tasks is known to be unstable and troublesome. To deal with that, this work proposes a hierarchical GAIL-based architecture (hGAIL) which decouples representation learning from the driving task to solve the autonomous navigation of a vehicle. The proposed architecture consists of two modules: a GAN (Generative Adversarial Net) which generates an abstract mid-level input representation, which is the Bird's-Eye View (BEV) from the surroundings of the vehicle; and the GAIL which learns to control the vehicle based on the BEV predictions from the GAN as input. hGAIL is able to learn both the policy and the mid-level representation simultaneously as the agent interacts with the environment. Our experiments made in the CARLA simulation environment have shown that GAIL exclusively from cameras (without BEV) fails to even learn the task, while hGAIL, after training exclusively on one city, was able to autonomously navigate successfully in 98% of the intersections of a new city not used in training phase.

description: Collaboration is an increasingly popular trend in libraries, archives, and museums. Whether projects make use of limited resources by pooling them or share the expense of building new resources, funding agencies are encouraging organizations to work together. However the study of collaboration in a library complex lags behind these opportunities. This case study takes an in-depth look into the tools, processes, and structures employed by a multi-institutional project planning group through interviews and examining documentation. The particular planning project studied here resulted from an administrative mandate and proceeded with the full support of an established consortial arrangement. The purpose of the study was to unveil factors and behaviors that facilitate successful collaboration under friendly circumstances. It explores the coordination processes involved when project planning participants have different roles, goals, and responsibilities.

description: Wir entwickeln einen neuen Ansatz zur Schätzung vom Conditional Value-at-Risk (CoVaR) von Finanzinstituten. Unsere Methode basiert auf Neural Network Quantilregression. Aufbauend auf den Ergebnissen der Schätzung modellieren wir Risiko-Spillover-Effekte zwischen Banken, indem wir marginale Effekte der Quantilregression berechnen. Wir erhalten ein zeitlich veränderliches Risikonetzwerk, dargestellt durch eine Adjazenzmatrix. Daraufhin schlagen wir drei systemische Risikomaße vor. Der Systemic Fragility Index und der Systemic Hazard Index identifizieren die anfälligsten und die gefährlichsten Firmen im Finanzsystem. Als drittes Maß schlagen wir den Systemic Network Risk Index vor, welcher das allgemeine systemische Risiko im Finanzsystem misst. Wir wenden unsere Methode auf die global systemrelevanten Banken aus den Vereinigten Staaten an. Unsere Resultate bestätigen bestehende Studien. Wir fanden heraus, dass das systemische Risiko während des Höhepunkts der Finanzkrise 2008 stark anstieg und nochmal in 2011 und 2015 nach einer kurzen Phase der Beruhigung.
description: We propose a novel approach to estimate the conditional value at risk (CoVaR) of financial institutions. Our approach is based on neural network quantile regression. Building on the estimation results we model systemic risk spillover effects across banks by considering the marginal effects of the quantile regression procedure. We obtain a time-varying risk network represented by an adjacency matrix. We then propose three measures for systemic risk. The Systemic Fragility Index and the Systemic Hazard Index are measures to identify the most vulnerable and most critical firms in the financial system, respectively. As a third risk measure we propose the Systemic Network Risk Index which represents the overall level of systemic risk. We apply our methodology to the global systemically relevant banks from the United States in a time period from 2007 until 2018. Our results are similar to previous studies about systemic risk. We find that systemic risk increased sharply during the height of the financial crisis in 2008 and again after a short period of easing in 2011 and 2015.

Πιο συγκεκριμένα, πραγματεύεται τη σημασία της γλώσσας και το ρόλο που διαδραματίζει η επικοινωνία στην πρακτική της κοινωνικής εργασίας με μειονοτικές ομάδες. Μέσα από την ανάδειξη συγκεκριμένων θεωρητικών προσεγγίσεων, εξετάζεται η λειτουργία της γλώσσας και ο τρόπος με τον οποίο οι λέξεις επιδρούν ψυχο-θεραπευτικά στο άτομο και (ανα)παράγουν μία συγκεκριμένη κοινωνική πραγματικότητα. Ειδικότερα, το ενδιαφέρον επικεντρώνεται στις περιπτώσεις όπου η ετικετοποίηση λειτουργεί στιγματιστικά στις μειονοτικές ομάδες. Ακόμα, στην εργασία εξετάζεται η σημασία που φέρει τόσο η λεκτική όσο και η μη λεκτική επικοινωνία, καθώς και οι επικοινωνιακές προκλήσεις που αναδύονται όταν υπάρχουν πολιτισμικές και γλωσσικές διαφορές, όταν ο εξυπηρετούμενος πρόκειται για άτομο με αναπηρία και όταν ο επαγγελματίας προβαίνει σε κατάχρηση της εξουσίας του. Επιπλέον, μία σειρά όρων παρατίθεται ως ενδεικτικά παραδείγματα για αποτελεσματική και συμπεριληπτική επικοινωνία. Ειδικότερα, πρόκειται για προτεινόμενους όρους που έχουν συγκεντρωθεί και εμπλουτιστεί με παραδείγματα, με τη χρήση των οποίων επιδιώκεται η μείωση του στίγματος. Τέλος, παρατίθενται τρία διαφορετικά μέσα που στοχεύουν στην ενίσχυση της επικοινωνίας. Συγκεκριμένα, πρόκειται για τις μεθόδους επικοινωνίας βασισμένες στην τέχνη, για τη διερμηνεία και για τις «cue cards», τεχνική που συνιστάται όταν η παροχή διερμηνείας δεν είναι εφικτή. Στις οδηγίες για την αποτελεσματική επικοινωνία συγκαταλέγονται, επίσης, τα προγράμματα ποικιλομορφίας ως μία εκπαιδευτική μέθοδος, ιδανική για τους επαγγελματίες και φοιτητές της κοινωνικής εργασίας, η οποία συμβάλλει στην προώθηση της έννοιας της ποικιλομορφίας και της συμπερίληψης.

description: We investigate a population of swarmalators, a mobile version of phase oscillators that both sync in time and swarm through space. We focus on a XY-type model of identical swarmalators running on a one-dimensional ring and subject to thermal noise. We uncover four distinct collective states, some of which capture the behavior of real-world swarmalators such as vinegar eels and sperm. Among these, the most intriguing is the `mixed state', which blends two of the other states. We present a comprehensive phase diagram from the Fourier mode analysis with a high accuracy, which is in excellent agreement with numerical simulation results. Our model serves as a tractable toy model for thermal systems that both self-synchronize and self-assemble interdependently.

description: There is a lack of evidence on whether to favor cerebroplacental ratio (CPR) or umbilicocerebral ratio (UCR) when assessing pregnancies at risk of fetal growth restriction. The Recent evidences highlight a significant heterogeneity in the methodology of previously published studies reporting reference ranges for Doppler indices, which may affect the clinical applicability of these charts. The aim of this study was to develop charts of UCR based upon a recently proposed standardized methodology and using quantile regression. This was a secondary analysis of a prospective cross-sectional study including low-risk singleton pregnancies between 24 and 40 weeks of gestation undergoing Doppler recordings. The UCR centile values were established by quantile regression at different gestational age intervals. Quantile regression analysis was used to build the UCR chart. 2516 low- risk singleton pregnancies were included in the analysis. UCR decreased with advancing gestational age. The 3rd, 5th 10th, 50th, 90th, 95th, and 97th centiles according to gestational age are provided, as well as equations to allow calculation of any other percentile. We have established gestational age-specific normative centiles reference limits for UCR.
Logarithmic Minimal Models with Robin Boundary Conditions

description: We consider general logarithmic minimal models ${\cal LM}(p,p')$, with $p,p'$ coprime, on a strip of $N$ columns with the $(r,s)$ Robin boundary conditions introduced by Pearce, Rasmussen and Tipunin. The associated conformal boundary conditions are labelled by the Kac labels $r\in{\Bbb Z}$ and $s\in{\Bbb N}$. The Robin vacuum boundary condition, labelled by $(r,s\!-\!\frac{1}{2})=(0,\mbox{$\textstyle \frac{1}{2}$})$, is given as a linear combination of Neumann and Dirichlet boundary conditions. The general $(r,s)$ Robin boundary conditions are constructed, using fusion, by acting on the Robin vacuum boundary with an $(r,s)$-type seam consisting of an $r$-type seam of width $w$ columns and an $s$-type seam of width $d=s-1$ columns. The $r$-type seam admits an arbitrary boundary field which we fix to the special value $ξ=-\tfracλ{2}$ where $λ=\frac{(p'-p)π}{2p'}$ is the crossing parameter. The $s$-type boundary introduces $d$ defects into the bulk. We consider the associated quantum Hamiltonians and calculate analytically the boundary free energies of the $(r,s)$ Robin boundary conditions. Using finite-size corrections and sequence extrapolation out to system sizes $N+w+d\le 26$, the conformal spectrum of boundary operators is accessible by numerical diagonalization of the Hamiltonians. Fixing the parity of $N$ for $r\ne 0$ and restricting to the ground state sequences $w=\big\lfloor\frac{|r|p'}{p}\big\rfloor$, $r\in{\Bbb Z}$ with the inverse $r=(-1)^{N+w+d}\big\lceil \frac{p w}{p'}\big\rceil$, we find that the conformal weights take the values $Δ^{p,p'}_{r,s-\frac12}$ where $Δ^{p,p'}_{r,s}$ is given by the usual Kac formula. The $(r,s)$ Robin boundary conditions are thus conjugate to scaling operators with half-integer values for the Kac label $s-\mbox{$\textstyle \frac{1}{2}$}$.

description: Free and Open Source Software is becoming increasingly popular, especially as a tool for  international development. One type of open source software getting more notice is  Greenstone. Greenstone is a suite of software for building and distributing digital library  software and developed by the New Zealand Digital Library Project at the University of  Waikato in cooperation with UNESCO and Human Info NGO of Belgium. The National  Information Standards Organization (NISO) created A Framework of Guidance for  Building Good Digital Libraries for developing organizations and donor organizations to  ensure the creation of high quality digital libraries. This paper presents an evaluation of  the Greenstone documentation manuals for evidence that they instruct readers of various  technological ability on the concepts illustrated by NISO's Framework. The  documentation manuals covered just over half of the principles. A major issue with the  documentation is that though it may mention a term or task, it does not explain the  importance of it. Improving the documentation manuals could potentially influence  Greenstone users to create digital libraries that are of a high quality, and consequently  make Greenstone an even more useful tool for international development.

description: In superconducting systems in which inversion and time-reversal symmetry are simultaneously broken the critical current for positive and negative current bias can be different. For superconducting systems formed by Josephson junctions (JJs) this effect is termed Josephson diode effect. In this work, we study the Josephson diode effect for a superconducting quantum interference device (SQUID) formed by a topological JJ with a 4$π$-periodic current-phase relationship and a topologically trivial JJ. We show how the fractional Josephson effect manifests in the Josephson diode effect with the application of a magnetic field and how tuning properties of the trivial SQUID arm can lead to diode polarity switching. We then investigate the AC response and show that the polarity of the diode effect can be tuned by varying the AC power and discuss differences between the AC diode effect of asymmetric SQUIDs with no topological JJ and SQUIDs in which one JJ is topological.

description: The diffusion of superoxide radical anions on the surface of TiO2 catalysts is theoretically considered as an important step in the kinetics of photocatalytic oxidation of toxic pollutants. A detailed analysis is performed to discriminate the effects of rotation, anion and adsorption bonds vibrations on the diffusion coefficient. A resonant dependence of the diffusivity on the lattice parameters of the TiO2 surface is discovered showing that the most rapid diffusion takes place when the lattice parameters are twice larger than the bond length of the superoxide radical anions. Whereas the rotation and vibrations normal to the catalyst surface are important, the anion bond vibrations do not affect the diffusivity due to their low amplitudes as compared to the lattice parameters.

description: Preeclampsia is one of the leading causes of maternal and fetal morbidity and mortality. The objective of our study was to study risk factors and complications associated with severe preeclampsia requiring intensive care unit (ICU) admission Retrospective comparative study over a period from 1st of January 2015 to 1st of January 2019 in the University’s maternity unit of South Reunion (Indian Ocean). Our sampling included all preeclamptic patients who delivered in the Southern part of the island. Patients admitted to intensive care unit (ICU) and those who remained in the maternity unit (controls) were reviewed. Out of 482 preeclampsia cases, 94 women (19.5%) needed a transfer in ICU, of which only 21 (4.3%) needed invasive intensive care. Mean length of stay was 2.4 ± 2.1 days. ICU admission was associated with HELLP syndrome (OR 8.5 [4.9–14.9], p<.001), severe post-partum hemorrhage (OR 5.86 [1.29–26.70], p=.01) and early onset of preeclampsia (<34 weeks gestation), 2.97 [1.9-4.7], p<.001), leading to higher rate of C-section (OR 2.83 [1.67–4.78], p<.001). There were three patients with a history of eclampsia and no case of maternal death was reported. Fetal prognosis was much poorer in maternal ICU admissions than in controls, with outcomes including lower birth weight (1776 vs. 2304 g, p<.001) and higher perinatal morbidity (infant respiratory distress syndrome 3.70 [1.94–7.05], p<.001) and mortality (<.001). Women needing invasive ICU represented 4.3% of preeclampsia cases. This experience is of interest for lower resource settings such as in countries like Madagascar where very intensive ICU means are very poor, but simpler ICU surveillance is possible. Fetal prognosis was poor though no maternal death was reported. Thus, a multidisciplinary approach of patients with preeclampsia should be encouraged; admission into ICU should be facilitated, as soon as any sign of severity and complications appears.

description: Mueller matrices are defined with respect to appropriate Cartesian reference frames for the representation of the states of polarization of the input and output electromagnetic waves. The polarimetric quantities that are invariant under rotations of the said reference frames about the respective directions of propagation (rotation transformations) provide particularly interesting physical information. Moreover, certain properties are also invariant with respect to the action of birefringent devices located at both sides of the medium under consideration (retarder transformations). The polarimetric properties that remain invariant under rotation and retarder transformations are analyzed and interpreted, providing significant parameterizations of Mueller matrices in terms of meaningful physical quantities.

In most of all existing ETDs repositories, students are required to manually type in these metadata, which discourages students' submission, especially when resubmissions are needed due to the errors found in the theses, because they have to type all the metadata again each time they submit the theses. By standardizing a method for capturing the metadata from the original documents, our project aims to enable digital repository, which hosts the ETDs collection, to automatically extract the metadata from the theses, making the submissions much easier and more convenient for the students.

description: Line Speed Publish/Subscribe Inter-networking (LIPSIN) is one of the proposed forwarding mechanisms in Information Centric Networking (ICN). It is a stateless source-routing approach based on Bloom filters. However, it has been shown that LIPSIN is vulnerable to brute-force attacks which may lead to distributed denial-of-service (DDoS) attacks and unsolicited messages. In this work, we propose a new forwarding approach that maintains the advantages of Bloom filter based forwarding while allowing forwarding nodes to statelessly verify if packets have been previously authorized, thus preventing attacks on the forwarding mechanism. Analysis of the probability of attack, derived analytically, demonstrates that the technique is highly-resistant to brute-force attacks.

description: Multiple-Input-Multiple-Output~(MIMO) signal detection is central to every state-of-the-art communication system, and enhancements in error performance and computation complexity of MIMO detection would significantly enhance data rate and latency experienced by the users. Theoretically, the optimal MIMO detector is the maximum-likelihood (ML) MIMO detector; however, due to its extremely high complexity, it is not feasible for large real-world communication systems. Over the past few years, algorithms based on physics-inspired Ising solvers, like Coherent Ising machines and Quantum Annealers, have shown significant performance improvements for the MIMO detection problem. However, the current state-of-the-art is limited to low-order modulations or systems with few users. In this paper, we propose an adaptive multi-stage Ising machine-based MIMO detector that extends the performance gains of physics-inspired computation to Large and Massive MIMO systems with a large number of users and very high modulation schemes~(up to 256-QAM). We enhance our previously proposed delta Ising formulation and develop a heuristic that adaptively optimizes the performance and complexity of our proposed method. We perform extensive micro-benchmarking to optimize several free parameters of the system and evaluate our methods' BER and spectral efficiency for Large and Massive MIMO systems (up to 32 users and 256 QAM modulation).

description: The use of non-prescribed drugs are common to pregnant women. It may lead to undesirable effects, such as birth defects. Study results on the occurrence and predictor of non-prescribed drug use among pregnant women throughout Ethiopia are highly variable and inconsistent. Therefore, the objective of this systematic review and meta-analysis was to estimate the pooled prevalence of non-prescribed drug use and predictors among pregnant women in Ethiopia. We systematically searched studies from the international databases, including PubMed, EMBASE, Web of Science, Science Direct, Google Scholar, the Cochrane Library and others. The meta-analysis was conducted using Stata15. I2 test and Egger’s test were used to assess the heterogeneity and publication bias respectively. The random-effect model was used to estimate the pooled prevalence of non-prescribed drug use at a 95% CI. Eleven studies with a total of 4492 pregnant women fulfilled the inclusion criteria and were included. The pooled national level non-prescribed drug use among pregnant women was 30.38% (95% CI: 20.28, 40.48). The highest use of non-prescribed drug among pregnant women was observed in Amhara region 36.71%, while the lowest was in Tigray region 9.67%, respectively. The most frequently consumed non prescribed drugs by pregnant mothers were paracetamol 34.38%, amoxicillin 14.73%, aspirin 4.25%, metronidazole 2.81% and ciprofloxacin 2.80%. Maternal previous history of self-medication, maternal illness during pregnancy and maternal marital status were significantly associated with women non-prescribed drug use during pregnancy. The overall prevalence of non- prescribed drug use among pregnant women in Ethiopia is relatively high, and varies across different regions. The most frequently consumed non- prescribed drug by pregnant mothers was paracetamol. Maternal; previous history of self-medication, illness during pregnancy and marital status were significantly associated with pregnant women non-prescribed drug use. Awareness of the possible side effects of taking non-prescribed drugs for all pregnant women is very relevant in the media and in the maternity ward. In particular, it is important to make clear to mothers who have a history of self-medication, to those who have a history of illness during pregnancy and to those who are pregnant, unmarried or divorced.

description: Fundamental forces of Nature are described by field theories, also known as gauge theories, based on a local gauge invariance. The simplest of them is quantum electrodynamics (QED), which is an example of an Abelian gauge theory. Such theories describe the dynamics of massless photons and their coupling to matter. However, in two spatial dimension (2D) they are known to exhibit gapped phases at low temperature. In the realm of quantum spin systems, it remains a subject of considerable debate if their low energy physics can be described by emergent gauge degrees of freedom. Here we present a class of simple two-dimensional models that admit a low energy description in terms of an Abelian gauge theory. We find rich phase diagrams for these models comprising exotic deconfined phases and gapless phases - a rare example for 2D Abelian gauge theories. The counter-intuitive presence of gapless phases in 2D results from the emergence of additional symmetry in the models. Moreover, we propose schemes to realize our model with current experiments using ultracold bosonic atoms in optical lattices.

description: At the core of every Holocaust institution, whether it be a museum or an archive is remembrance and memorializing.  This mission is often fulfilled through community outreach and education, and is a process that requires the participation of the public.  The advent of the Internet has given these institutions a new tool through which to perpetrate memorializing.  Through studying the websites of Yad Vashem, The United States Holocaust Memorial Museum, Simon Wiesenthal Center Museum of Tolerance, The Fortunoff Video Archive, and The Shoah Foundation, we can see and better understand how the Internet can be used for Holocaust Memorializing. The results of studying these sites show that these institutions are using tools like YouTube to extend the reach of their video testimonies and user content generated databases to collect names and information about victims of the Shoah. Other historical repositories can improve their access and outreach by observing Holocaust institutions.

A Survey of the Attitudes of Public Library Patrons on Submitting a Personal DNA Sample for Genetic Research
Creators: name: Bahnson, Jane P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009
Subjects: Medical information

description: Research utilizing large genetic databases containing individual contributors' personal DNA information has led to the discovery of disease associations and medical treatment breakthroughs. Willingness among the public to submit a DNA sample for medical research is not universal. To better understand reasons why people may or may not want to contribute their personal DNA for research, a survey of public library patrons was conducted. The results show that fear of health insurers, employers, and law enforcement learning the results are impediments to DNA donation that current legal protections against discrimination alone may not satisfy. Nonetheless there is strong support for medical genetic research among the public as long as confidentiality and anonymity are maintained.

description: Several biases are known to influence funding decisions in crowdfunding. Among these biases is herding behavior; that is, the tendency to imitate the funding decisions of others. Herding is a very robust phenomenon in crowdfunding and uniformly characterized as a positive reinforcement effect. We challenge this characterization and ask whether the funding decisions of others may in fact have a negative effect and lead to a reduction of follow-up funding decisions if they are very small – a phenomenon to which we refer as reverse herding. We conducted a field experiment at a reward-based crowdfunding platform by randomly contributing small funding amounts to some campaigns while keeping track of a non-manipulated control group. Our findings support the notion of reverse herding. The number and amount of contributions by the crowd following our small funding amounts were fewer and smaller than in the control group. We discuss reverse herding in relation to established crowdfunding concepts and formulate a dilemma of small contributions: Although small contributions are a fundamental part of crowdfunding, they can also cause the detrimental effect of reverse herding. Practical and theoretical implications of reverse herding are discussed and several opportunities for future research are outlined.
