description: We analyse the cluster color-magnitude relation (CMR) for early-type galaxies in two of the richer clusters in the z ~ 0.9 supercluster system to derive average ages and formation redshifts for the early-type galaxy population. Both clusters were observed with the Advanced Camera for Surveys aboard the {\it Hubble Space Telescope} through the F606W and F814W filters, which brackets the rest-frame 4000 Åbreak at the cluster redshifts of z\sim 0.9. We fit the zeropoint and slope of the red cluster sequence, and model the scatter about this relation to estimate average galaxy ages and formation redshifts. We find intrinsic scatters of 0.038-0.053 mag in ($V_{606}-I_{814}$) for the E and E+S0 populations, corresponding to average ages of 3.5-3.7 Gyr and formation redshifts z_{f}=2.4-2.6. We find at least one significant difference between the Cl1604+4304 and Cl1604+4321 early-type CMRs. Cl1604+4321, the less X-ray luminous and massive of the two, lacks bright L^* ellipticals. We combine the galaxy samples to fit a composite CMR down to 0.15L^*, and find that the slope of the combined cluster CMR is significantly steeper than for RX J0152.7-1357 but consistent with MS 1054-03, both at similar redshift. The slope of the Cl1604 CMR at the bright end (L > 0.5L^*) is flatter and consistent with the CMR slopes found for other high redshift clusters. We find evidence for increasing scatter with increasing magnitude along the early-type CMR, consistent with a 'downsizing' scenario, indicating younger mean ages with decreasing galaxy mass.

description: A number of O stars are suspected to have (weak) magnetic fields because of the observed cyclical variability in their UV wind-lines. However, direct detections of these magnetic fields with optical spectropolarimetry have proven to be very difficult. We have searched for non-thermal radio emission, which would be a strong indication for the presence of a magnetic field. Of our 5 selected candidate magnetic O stars, 3 are detected: $ξ$ Per, which we find to have a non-thermal spectrum, and $λ$ Cep and $α$ Cam which show a thermal spectrum. We also find that the fluxes are lower than the expected free-free (thermal) contribution of the stellar wind. This is in agreement with recent findings that the mass-loss rates from O stars using H$α$ are overestimated because of clumping in the inner part of the stellar wind.

description: The learning and usage of an API is supported by official documentation. Like source code, API documentation is itself a software product. Several research results show that bad design in API documentation can make the reuse of API features difficult. Indeed, similar to code smells or code antipatterns, poorly designed API documentation can also exhibit 'smells'. Such documentation smells can be described as bad documentation styles that do not necessarily produce an incorrect documentation but nevertheless make the documentation difficult to properly understand and to use. Recent research on API documentation has focused on finding content inaccuracies in API documentation and to complement API documentation with external resources (e.g., crowd-shared code examples). We are aware of no research that focused on the automatic detection of API documentation smells. This paper makes two contributions. First, we produce a catalog of five API documentation smells by consulting literature on API documentation presentation problems. We create a benchmark dataset of 1,000 API documentation units by exhaustively and manually validating the presence of the five smells in Java official API reference and instruction documentation. Second, we conduct a survey of 21 professional software developers to validate the catalog. The developers agreed that they frequently encounter all five smells in API official documentation and 95.2% of them reported that the presence of the documentation smells negatively affects their productivity. The participants wished for tool support to automatically detect and fix the smells in API official documentation. We develop a suite of rule-based, deep and shallow machine learning classifiers to automatically detect the smells. The best performing classifier BERT, a deep learning model, achieves F1-scores of 0.75 - 0.97.

description: We consider navigation or search schemes on networks which have a degree distribution of the form $P(k) \propto \exp(-k^γ)$. In addition, the linking probability is taken to be dependent on social distances and is governed by a parameter $λ$. The searches are realistic in the sense that not all search chains can be completed. An estimate of $μ=ρ/s_d$, where $ρ$ is the success rate and $s_d$ the dynamic path length, shows that for a network of $N$ nodes, $μ\propto N^{-δ}$ in general. Dynamic small world effect, i.e., $δ\simeq 0$ is shown to exist in a restricted region of the $λ-γ$ plane.

Ειδικότερα,η ερευνήτρια συνδυάζοντας το πείραμα με την τεκμηρίωση, την προσωπική αναζήτηση με την ερευνητική διαδικασία επιχειρεί να αναδείξει τη συμβολή που έχουν τα σχεδιασμένα προγράμματα εκπαιδευτικού δράματος στην κοινωνική ανάπτυξη των παιδιών. Η μελέτη ακολούθησε την αρχή της μεθοδολογικής τριγωνοποίησης, δηλαδή, τη χρήση δύο ή περισσότερων μεθόδων συλλογής δεδομένων. Ειδικότερα, τα δεδομένα της έρευνάς μας αντλήθηκαν μέσω ενός κοινωνιογράμματος, των ημιδομημένων συνεντεύξεων σε ομάδες εστίασης και ενός ημερολογίου παρατηρήτριας και παιδιών. Επίσης έγινε ποσοτική καταγραφή συναισθημάτων και εναλλαγής στη διάθεση των παιδιών σε κάθε έναρξη και λήξη των εργαστηρίων με τη χρήση ενός «διαθεσόμετρου». Η ανάλυση των δεδομένων της έρευνάς μας έδειξε μετακινήσεις σε επίπεδο δυναμικής της ομάδας, ομαδικότητας, συνεργασίας, ανάπτυξης φιλικών σχέσεων καθώς και έκφρασης και ανταλλαγής συναισθημάτων και συγκινήσεων. Στο ίδιο πνεύμα, αναδείχτηκε ο ρόλος του εμψυχωτή-συντονιστή που μέσω των θεατρικών τεχνικών βοηθά να βρει δημιουργική διέξοδο ο εσωτερικός κόσμος του παιδιού και να υλοποιηθεί κυρίως ο μέγιστος στόχος της εκπαίδευσης που είναι η σύνδεση του θεάτρου με τη ζωή.
description: The present study explores the effects of educational drama on the way in which a team that plays organises and on the relations between the children / players. In particular, the researcher attempts to underline the contribution that planned programmes of educational drama have on children’s social development combining experiment with substantiation and personal quest with the research process. The study followed the principle of methodological triangulation, namely, the usage of two or more methods of collecting data. Specifically, the data of the research were derived through a sociogram, semi-structured interviews of teams of focus and a diary by the observer and by the children. Moreover, a record of sentiments and of the interchange in children’s mood took place in every start and finish of the workshops with the use of a “mood-metre”. The analysis of the data of the present study showed shifts with regard to the dynamics of the team, the team spirit, the collaboration, the development of friendships as well as the expression and exchange of feelings and emotional moments. In the same spirit, the study brings to prominence the animator’s / co-ordinator’s role, who tries to facilitate the creative outlet of the child’s inner world through theatrical techniques and, above all, helps materialize the greatest goal of education which is the connection of theatre with life.

description: This paper pays close attention to the cross-modality visible-infrared person re-identification (VI Re-ID) task, which aims to match pedestrian samples between visible and infrared modes. In order to reduce the modality-discrepancy between samples from different cameras, most existing works usually use constraints based on Euclidean metric. Because of the Euclidean based distance metric strategy cannot effectively measure the internal angles between the embedded vectors, the existing solutions cannot learn the angularly discriminative feature embedding. Since the most important factor affecting the classification task based on embedding vector is whether there is an angularly discriminative feature space, in this paper, we present a new loss function called Enumerate Angular Triplet (EAT) loss. Also, motivated by the knowledge distillation, to narrow down the features between different modalities before feature embedding, we further present a novel Cross-Modality Knowledge Distillation (CMKD) loss. Benefit from the above two considerations, the embedded features are discriminative enough in a way to tackle modality-discrepancy problem. The experimental results on RegDB and SYSU-MM01 datasets have demonstrated that the proposed method is superior to the other most advanced methods in terms of impressive performance.

Πιο συγκεκριμένα, όσον αφορά την ετερογενή φωτοκαταλυτική οξείδωση, εξετάστηκαν: η επίδραση του pH, η συγκέντρωση και το είδους του καταλύτη, η συγκέντρωση της προς μελέτη χρωστικής και η προσθήκη οξειδωτικών ουσιών (Fe3+, H2O2). Ενώ στην περίπτωση της ομογενούς φωτοκαταλυτικής οξείδωσης, μελετήθηκαν η συγκέντρωση του κάθε οξειδωτικού (Fe3+ και H2O2), αλλά και το είδος της ακτινοβολίας (UV-A και Vis). Ιδιαίτερα σημαντική κρίθηκε η δράση του H2O2, του οποίου η διάσπαση δεν επιβαρύνει με επιπλέον ρύπους, καθώς η προσθήκη του σε κάθε περίπτωση συνεισέφερε σε μεγάλο βαθμό στην ταχύτητα της μεθόδου.
description: The degradation and mineralization of the Light Green SF Yellowish dye through heterogeneous and homogeneous photocatalytic oxidation using artificial light was studied. More specifically, with regard to heterogeneous photocatalytic oxidation, the following were examined: the effect of pH, the concentration and type of catalyst, the concentration of the dye and the addition of oxidizing agents (Fe3 +, H2O2), while in the case of homogeneous photocatalytic oxidation, the concentration of each oxidant (Fe3 + and H2O2) was studied, as well as the type of radiation (UV-A and Vis). The action of H2O2, the decomposition of which does not burden with additional pollutants, was considered particularly important, as its addition in any case contributed greatly to the speed of the method.

description: Στην παρούσα εργασία, αναλύονται τα περικειμενικά στοιχεία εφηβικών ιστορικών μυθιστορημάτων, με σκοπό τον εντοπισμό των λειτουργιών και των χαρακτηριστικών τους. Για την εξέταση του θέματος, αναζητήθηκαν οι μελέτες που αφορούν το ιστορικό μυθιστόρημα και την εφηβική λογοτεχνία. Ακόμα, δόθηκε ιδιαίτερη έμφαση στο βιβλίο Paratexts: Thresholds of Interpretation (Genette, 1997), που παρέχει λεπτομερείς πληροφορίες σχετικά με τα περικειμενικά στοιχεία των λογοτεχνικών βιβλίων. Για την ανάλυση του περικειμένου, χρησιμοποιήθηκε το μεθοδολογικό εργαλείο PLF (Peritextual Literacy Framework), που κατατάσσει τα περικειμενικά στοιχεία σε έξι κατηγορίες, με βάση τη λειτουργία τους. Το υλικό εξέτασης αποτέλεσαν δεκαέξι ιστορικά μυθιστορήματα για εφήβους, που εκδόθηκαν κατά την εικοσαετία 1960-1980. Μετά την ανάλυση, διαπιστώθηκε ότι οι εκδοτικοί οίκοι και οι συγγραφείς επιδιώκουν, μέσα από το περικείμενο, την διαφήμιση, την καλύτερη και βαθύτερη κατανόηση του λογοτεχνικού κειμένου αλλά και την ευκολότερη περιήγηση του αναγνώστη στο βιβλίο. Από την άλλη πλευρά, παρατηρήθηκε ότι δεν δίνεται καθόλου έμφαση στην απόδειξη της εγκυρότητας των έργων, παρόλο που το είδος του ιστορικού μυθιστορήματος προϋποθέτει την τεκμηρίωση των αφηγηθέντων γεγονότων.
description: The present study analyzes the peritextual elements of adolescent historical novels, in order to identify their functions and characteristics. For the subject’s examination, the studies regarding historical fiction novels and adolescent literature were sought. Furthermore, special emphasis was placed on the book Paratexts: Thresholds of Interpretation (Genette, 1997), which provides detailed information regarding the peritextual elements. To analyze the peritext, we used the methodological tool PLF (Peritextual Literacy Framework), which categorizes the functions of peritext into six types. As far as research material is concerned, we examined sixteen historical novels for adolescents, that were published during 1960-1980. The research findings indicate that, via the peritext, the publisher and the author aim at advertising the book, increasing the reader’s understanding of the text and enabling an easier browsing through the book. On the other hand, it was shown that no emphasis is given in proving the text’s verity, even though historical novels require the narration’s documentation.
How good must single photon sources and detectors be for efficient linear optical quantum computation?

description: We present a scheme for linear optical quantum computation (LOQC) which is highly robust to imperfect single photon sources and inefficient detectors. In particular we show that if the product of the detector efficiency with the source efficiency is greater than 2/3, then efficient LOQC is possible. This threshold is many orders of magnitude more relaxed than those which could be inferred by application of standard results in fault tolerance. The result is achieved within the cluster state paradigm for quantum computation.

description: This paper analyzes the joint assessment of quality, spatial and social presence, empathy, attitude, and attention in three conditions: (A)visualizing and rating the quality of contents in a Head-Mounted Display (HMD), (B)visualizing the contents in an HMD,and (C)visualizing the contents in an HMD where participants can see their hands and take notes. The experiment simulates an immersive communication where participants attend conversations of different genres and from different acquisition perspectives in the context of international experiences. Video quality is evaluated with Single-Stimulus Discrete Quality Evaluation (SSDQE) methodology. Spatial and social presence are evaluated with questionnaires adapted from the literature. Initial empathy is assessed with Interpersonal Reactivity Index(IRI) and a questionnaire is designed to evaluate attitude. Attention is evaluated with 3 questions that had pass/fail answers. 54 participants were evenly distributed among A, B, and C conditions taking into account their international experience backgrounds, obtaining a diverse sample of participants. The results from the subjective test validate the proposed methodology in VR communications, showing that video quality experiments can be adapted to conditions imposed by experiments focused on the evaluation of socioemotional features in terms of contents of long-duration, actor and observer acquisition perspectives, and genre. In addition, the positive results related to the sense of presence imply that technology can be relevant in the analyzed use case. The acquisition perspective greatly influences social presence and all the contents have a positive impact on all participants on their attitude towards international experiences. The annotated dataset, Student Experiences Around the World dataset (SEAW-dataset), obtained from the experiment is made publicly available.

description: This article is devoted to the study of monoids which can be endowed with a shuffle product with coefficients in a semiring. We show that, when the multiplicities do not belong to a ring with prime characteristic, such a monoid is a monoid of traces. When the characteristic is prime, we give a decomposition of the congruences $\equiv$ (or relators $R$) such that $A^*/\_\equiv=< A; R>$ admits a shuffle product. This decomposition involves only addition of primitive elements to the successive quotients. To end with, we study the compatibility with Magnus transformation and examine the case of congruences which are homogeneous for some weight function. The existence of such a weight function is also showed for congruences of depth one.

description: A Paleoparasitologia foi uma linha de pesquisa nomeada por um pesquisador brasileiro Dr. Luiz Fernando Ferreira (1936-2018). Essa ciência estuda a evolução da vida na terra por meio dos parasitos e microrganismos, e para isso pesquisa materiais como múmias, âmbar, coprólito, dentre outros, tendo assim o potencial de atrair a atenção do público infanto-juvenil. A animação tem se mostrado como um recurso áudio visual que pode impactar positivamente o processo de alfabetização científica. Assim, na Universidade Federal Fluminense, onde essa linha de pesquisa é desenvolvida no Programa de Pós-graduação em Microbiologia e Parasitologia Aplicadas, criamos um projeto de extensão denominado “Paleoparasitologia para Todos” que é oferecido anualmente desde 2017, onde além de oficinas nas escolas para divulgação científica desta linha de pesquisa e suas descobertas, desenvolvemos vários materiais paradidáticos de acesso aberto, depositados no repositório institucional da UFF https://app.uff.br/riuff/ e também no nosso blog https://paleoparasitologiaparatodos.wordpress.com/. Agora estamos desenvolvendo animações para divulgar pesquisas paleoparasitológicas para o público infantil, duas já foram criadas e duas estão em andamento, e se encontram no canal no YouTube do projeto https://www.youtube.com/channel/UCH1S2h0iG94DmYmNNZ1gsVQ.

These deviations include, amongst others, maturational defects of the brain hemispheres and atypical brain lateralization.
Comparing Dynamical and Stellar Population Mass-to-Light Ratio Estimates

description: We investigate the mass-to-light ratios of stellar populations as predicted by stellar population synthesis codes and compare those to dynamical/gravitational measurements. In Bell & de Jong (2001) we showed that population synthesis models predict a tight relation between the color and mass-to-light ratio of a stellar population. The normalization of this relation depends critically on the shape of the stellar IMF at the low-mass end. These faint stars contribute significantly to the mass, but insignificantly to the luminosity and color of a stellar system. In Bell & de Jong (2001) we used rotation curves to normalize the relation, but rotation curves provide only an upper limit to the stellar masses in a system. Here we compare stellar and dynamical masses for a range of stellar systems in order to constrain the mass normalization of stellar population models. We find that the normalization of Bell & de Jong (2001) should be lowered by about 0.05-0.1 dex in M/L. This is consistent with a Kroupa (2001), Chabrier (2003) or a Kennicutt (1983) IMF, but does not leave much room for other unseen components.

description: Spin backflow and spin-memory loss have been well established to considerably lower the interfacial spin transmissivity of metallic magnetic interfaces and thus the energy efficiency of spin-orbit torque technologies. Here we report that spin backflow and spin-memory loss at Pt-based heavy metal/ferromagnet interfaces can be effectively eliminated by inserting an insulating paramagnetic NiO layer of optimum thickness. The latter enables the thermal magnon-mediated essentially unity spin-current transmission at room temperature due to considerably enhanced effective spin-mixing conductance of the interface. As a result, we obtain dampinglike spin-orbit torque efficiency per unit current density of up to 0.8 as detected by the standard technology ferromagnet FeCoB and others, which reaches the expected upper-limit spin Hall ratio of Pt. We establish that Pt/NiO and Pt-Hf/NiO are two energy-efficient, integration-friendly, and high-endurance spin-current generators that provide >100 times greater energy efficiency than sputter-deposited topological insulators BiSb and BiSe. Our finding will benefit spin-orbitronic research and advance spin-torque technologies.

The head nurses’ perceptions of the impact of deinstitutionalization on the chronically mentally ill
Creators: name: Sinnen, K. Leila
Publisher: name: University of British Columbia
Year: 2008

description: This study describes head nurses' perceptions of the impact of deinstitutionalization on persons with chronic mental illness. A phenomenological approach is the methodology used in this study. Data were collected by use of an in-depth semi-structured interview. The participants in the study were seven head nurses from a large psychiatric institution in Western Canada. Themes derived from the data were abstracted into three content categories. The content categories are contributing factors, impact on the individual and facilitating factors. Major themes under each of the content categories are described. The findings reveal that head nurses perceive that deinstitutionalization has negative and positive effects on the chronic mentally ill. The negative effects are stigma, homelessness and the revolving door syndrome. Positive effects of deinstitutionalization can be a better quality of life with adequate communication, patient preparation, education and resources/facilities in the community. The findings also show that head nurses perceive that some persons with chronic mental illness may require care in a psychiatric institution for most of their lives. The implications that deinstitutionalization has for nursing practice, education, administration and research are presented.

description: Numerically we simulate the effect of optimized coherent control pulses with a finite duration on a qubit in a bath of spins. The pulses of finite duration are compared with ideal instantaneous pulses. In particular, we show that properly designed short pulses can approximate ideal instantaneous pulses up to a certain order in the shortness of the pulse. We provide examples of such pulses, quantify the discrepancy from the ideal case and compare their effect for various ranges of the coupling constants.

Degenerate sterile neutrino dark matter in the cores of galaxies

description: We study the distribution of fermionic dark matter at the center of galaxies using NFW, Moore and isothermal density profiles and show that dark matter becomes degenerate for particle masses of a few {\rm keV} and for distances less than a few parsec from the center of our galaxy. A compact degenerate core forms after galaxy merging and boosts the growth of supermassive black holes at the center of galaxies. To explain the galactic center black hole of mass of $\sim 3.5 \times 10^{6}M_{\odot}$ and a supermassive black hole of $\sim 3 \times 10^{9}M_{\odot}$ at a redshift of 6.41 in SDSS quasars, we require a degenerate core of mass between $3 \times 10^{3} M_{\odot}$ and $3.5 \times 10^{6}M_{\odot}$. This constrains the mass of the dark matter particle between $0.6 {\rm keV}$ and $82 {\rm keV}$. The lower limit on the dark matter mass is improved to {\rm 7 keV} if exact solutions of Poisson's equation are used in the isothermal power law case. We argue that the constrained particle could be the long sought dark matter of the Universe that is interpreted here as a sterile neutrino.

description: The release of dashcam footage showing a Chicago Police Department (CPD) officer fatally shooting 17-year-old Laquan McDonald in 2015 placed extraordinary scrutiny on CPD to avoid another controversial case of police misconduct. Using data on arrests as well as traffic stops and searches, we assess whether the quantity and quality of policing in Chicago changed after the video documenting this vivid incident of deadly force was released. We find that while both felony and misdemeanor arrest rates declined after Laquan’s murder was publicized, this event had no discernable impact on traffic stop rates, contraband hit rates, or the ratio of felony to misdemeanor arrests. Supplemental analyses reveal that declines in felony arrest rates were most pronounced in majority-Black districts due to reductions in drug possession and firearm arrests. Our findings provide nuanced evidence of a depolicing effect that may reflect attempts by CPD to reclaim legitimacy following this pivotal event.
Ion Charge States in the Fast Solar Wind: New Data Analysis and Theoretical Refinements

description: We present a further investigation into the increased ionization observed in element charge states in the fast solar wind compared to its coronal hole source regions. Once ions begin to be perpendicularly heated by ion cyclotron waves and execute large gyro-orbits, density gradients in the flow can excite lower hybrid waves that then damp by heating electrons in the parallel direction. We give further analysis of charge state data from polar coronal holes at solar minimum and maximum, and also from equatorial coronal holes. We also consider further the damping of lower hybrid waves by ions and the effect of non-Maxwellian electron distribution functions on the degree of increased ionization, both of which appear to be negligible for the solar wind case considered here. We also suggest that the density gradients required to heat electrons sufficiently to further ionize the solar wind can plausibly result from the turbulent cascade of MHD waves.

description: Despite advances in police practices, national case clearance rates of violent crimes are at an all-time low. One recent trend in American policing involves the rapid deployment of various technology-derived information sources to police prior to, during, and immediately after their initial response to crime incidents. Housed within centralized local-level police department units, these often called “real-time crime centers” (RTCCs) have capitalized on technological innovations to harness a host of information with the intention of improving the ability of police to manage crime. To date, however, very little is known about their ability to improve police practice or their impact on crime solvability. This study entails the first to assess the impact of RTCC technologies on violent crime incident case clearances and time-to-clearance using a multi-method, quasi-experimental design. Results indicated after controlling for neighborhood, crime type, and case-level characteristics, RTCC-assisted cases had 66% better odds of being cleared compared to a randomly drawn control sample of cases not receiving RTCC support. Further, after controlling for case-level characteristics, no significant differences were found between the clearance times of RTCC-assisted and control sample cases. Implications for police practice are discussed.

description: In this work, we consider the relativistic Duffin-Kemmer-Petiau equation for spin-one particles with a nonminimal vector interaction in the presence of minimal uncertainty in momentum. By using the position space representation we exactly determine the bound-states spectrum and the corresponding eigenfunctions. We discuss the effects of the deformation and nonminimal vector coupling parameters on the energy spectrum analytically and numerically.
