description: The magnetic exchange bias between epitaxial thin films of the multiferroic (antiferromagnetic and ferroelectric) hexagonal YMnO3 oxide and a soft ferromagnetic (FM) layer is used to couple the magnetic response of the ferromagnetic layer to the magnetic state of the antiferromagnetic one. We will show that biasing the ferroelectric YMnO3 layer by an appropriate electric field allows modifying and controlling the magnetic exchange bias and subsequently the magnetotransport properties of the FM layer. This finding may contribute to pave the way towards a new generation of electric-field controlled spintronics devices.

description: (Abridged) We present B, R, and I-band selected galaxy catalogues based on the Munich Near-Infrared Cluster Survey (MUNICS) which, together with the K-selected sample, serve as an important probe of galaxy evolution in the redshift range 0 < z < 2. Furthermore, used in comparison they are ideally suited to study selection effects. The construction of the B, R, and I-selected photometric catalogues, containing ~9000, ~9000, and ~6000 galaxies, respectively, is described in detail. The catalogues reach 50% completeness limits for point sources of B ~ 24.5mag, R ~ 23.5mag, and I ~ 22.5mag and cover an area of about 0.3 square degrees. Photometric redshifts are derived for all galaxies with an accuracy of dz/(1+z) ~ 0.057. We investigate the influence of selection band and environment on the specific star formation rate (SSFR). We find that K-band selection indeed comes close to selection in stellar mass, while B-band selection purely selects galaxies in star formation rate. We use a galaxy group catalogue constructed on the K-band selected MUNICS sample to study possible differences of the SSFR between the field and the group environment, finding a marginally lower average SSFR in groups as compared to the field, especially at lower redshifts. The field-galaxy luminosity function in the B and R band as derived from the R-selected sample evolves out to z ~ 2 in the sense that the characteristic luminosity increases but the number density decreases. This effect is smaller at longer rest-frame wavelengths and gets more pronounced at shorter wavelengths. Parametrising the redshift evolution of the Schechter parameters as M*(z) = M*(0) + a ln(1+z) and Phi*(z) = Phi*(0) (1+z)^b we find evolutionary parameters a ~ -2.1 and b ~ -2.5 for the B band, and a ~ -1.4 and b ~ -1.8 for the R band.

description: With an increase in mobile and camera devices' popularity, digital content in the form of images has increased drastically. As personal life is being continuously documented in pictures, the risk of losing it to eavesdroppers is a matter of grave concern. Secondary storage is the most preferred medium for the storage of personal and other images. Our work is concerned with the security of such images. While encryption is the best way to ensure image security, full encryption and decryption is a computationally-intensive process. Moreover, as cameras are getting better every day, image quality, and thus, the pixel density has increased considerably. The increased pixel density makes encryption and decryption more expensive. We, therefore, delve into selective encryption and selective blurring based on the region of interest. Instead of encrypting or blurring the entire photograph, we only encode selected regions of the image. We present a comparative analysis of the partial and full encryption of the photos. This kind of encoding will help us lower the encryption overhead without compromising security. The applications utilizing this technique will become more usable due to the reduction in the decryption time. Additionally, blurred images being more readable than encrypted ones, allowed us to define the level of security. We leverage the machine learning algorithms like Mask-RCNN (Region-based convolutional neural network) and YOLO (You Only Look Once) to select the region of interest. These algorithms have set new benchmarks for object recognition. We develop an end to end system to demonstrate our idea of selective encryption.

title: Tanzania's Law on Child Adoption, with a Special Focus on Adoptions with an International Element : In the Best Interest of the Child?

Subjects: subject: Child law

subject: 340

description: This study presents an exploration of the socio-legal foundations and traditions that govern alternative child care in a society bound by plural legal orders. It traces the problem of children without parental care in Mainland Tanzania to depict its magnitude and causes. Recognising the alleged weakening of the customary-law-regulated traditional child care system, the study looks at the formal alternative child care solutions under state law. The research presented is centred on child adoption as the most long-standing statutory measure offering a permanent family-based solution to the problem. Further, considering the prevalent socio-cultural and economic situation in Tanzania that defines the leading type of adopters, the study is designed to concentrate on adoptions by non-resident Tanzanians and resident non-Tanzanians. These two types of adoptions are categorised in this study as child adoptions with an international element. The examination of the law and practice of child adoption generally, and of adoptions with an international element in particular, is guided by the question ‘What is in the best interests of the child?’. The best interests of the child principle serves as a yardstick against which the capacity of the legal, policy, and institutional framework to manage child adoptions is measured in the study. Together with this framework, an evaluation of the child adoption practice, specifically regarding adherence to the law and protection of children in adoption, is made. Recognising the central role that ‘street-level bureaucrats’ play in the adoption process, the study also considers the effects on the process of their workplace dilemmas and coping mechanisms. Lastly, based on statistics of registered adoptions, the potential of child adoption as a solution to the problem of children without parental care and protection in Tanzania is reflected on. To conclude the study, answers are given to the main research questions based on the research findings. Hoping for a better way forward, ways to improve child adoption law and practice in Tanzania are recommended.

Despite the more complicated Wald formula for the entropy of D1D5p black holes in ten dimensions, their entropy is given by entropy function at its extremum point. We use this method for computing the entropy of the system both at the level of supergravity and for its higher order alpha'^3R^4 corrections.

In this paper, we prove that an arrangement has an $\mathbb{F}_1$-structure if and only if it is Boolean. We also prove that the arrangement in the cycle space of a graph is Boolean if and only if the cycle space has a basis consisting of cycles such that any two of them do not share edges.

An E9 multiplet of BPS states

description: We construct an infinite E9 multiplet of BPS states for 11D supergravity. For each positive real root of E9 we obtain a BPS solution of 11D supergravity, or of its exotic counterparts, depending on two non-compact transverse space variables. All these solutions are related by U-dualities realised via E9 Weyl transformations in the regular embedding of E9 in E10, E10 in E11. In this way we recover the basic BPS solutions, namely the KK-wave, the M2 brane, the M5 brane and the KK6-monopole, as well as other solutions admitting eight longitudinal space dimensions. A novel technique of combining Weyl reflexions with compensating transformations allows the construction of many new BPS solutions, each of which can be mapped to a solution of a dual effective action of gravity coupled to a certain higher rank tensor field. For real roots of E10 which are not roots of E9, we obtain additional BPS solutions transcending 11D supergravity (as exemplified by the lowest level solution corresponding to the M9 brane). The relation between the dual formulation and the one in terms of the original 11D supergravity fields has significance beyond the realm of BPS solutions. We establish the link with the Geroch group of general relativity, and explain how the E9 duality transformations generalize the standard Hodge dualities to an infinite set of `non-closing dualities'.

The effects of cooperative learning on the on-task behavior and attitudes toward learning and school of young adolescents
Creators: name: Neilson, Donna L.
Publisher: name: University of British Columbia
Year: 2008

description: This research investigated the effect that cooperative learning had on increasing the on-task behavior and formation of attitudes toward learning and school of young adolescents. A quasi-experimental study was conducted on a sample of 27 Grade 6 students. Embedded in this study was a detailed case study of six individuals. The teacher-researcher used a pre-posttest design employing the Harter Scale of Intrinsic Versus Extrinsic Orientation In The Classroom (1980) to measure the classroom orientation of all students and to determine their motivation for learning. T-tests and multivariate analyses were conducted on the motivational and informational components of the scale. In addition, a non-equivalent time samples design was used to investigate the on-task behavior of the 6 subjects selected for case study. The data results were analyzed using a single case experimental design of Split Middle Method Of Trend Analysis. Additional informal measures and students' journal writing provided further qualitative data to indicate students’ attitudes toward learning and school. Factors of gender and academic ability were considered. The major findings of the research were that cooperative learning increased the on-task behavior of young adolescents and their intrinsic orientation in the classroom, thus positively affecting motivation and attitudes toward learning. Gender specific data revealed that male scores significantly increased on the motivational components whereas female scores increased on the informational components of the Scale. Data also provided documentation for quality of interaction between peers as it influenced effective group functioning. The study concludes with recommendations for educators implementing cooperative learning for use with young adolescents.

description: We present a preliminary analysis of the stellar populations in the central parsecs of a sample of 22 Seyfert 2 galaxies, based on a careful separation of nebular emission and stellar light in high-spatial resolution HST-STIS spectra. 10% of the surveyed nuclei display stellar populations of intermediate age, 1-2 Gyr old, whereas the remaining targets appear to be evenly split between objects showing only very old stellar populations and nuclei requiring also an additional blue featureless component, which we characterise by means of very young, few-Myr-old stars. The small fraction of stellar population of intermediate age seems to argue against the presence of such a young component, however, since the short lifetime of O-stars would imply recurrent star-formation episodes and the build-up over the last 1-2 Gyr of a detectable intermediate-age population. Additionally, a correlation between the luminosity of such a blue component and the emission from highly-ionised species, together with the general absence of Wolf-Rayet features, further suggests that the featureless continuum arises from the central engine rather than from star-forming regions. We discuss our results in the framework of the unification paradigm and of models for star formation close to supermassive black holes.

description: The relaxation time approximation (RTA) is a well known method of describing the time evolution of a statistical ensemble by linking distributions of the variables of interest at different stages of their temporal evolution. We show that if all the distributions occurring in the RTA have the same functional form of a quasi-power Tsallis distribution the time evolution of which depends on the time evolution of its control parameter, nonextensivity $q(t)$, then it is more convenient to consider only the time evolution of this control parameter.

title: Balzac and the notion of the vol décent
title: a sanction of deceit in La Comédie humaine
titleType: Subtitle
Creators: name: Shields, Martin
Publisher: name: Lancaster University
Year: 2018

description: The Balzacian notion of the vol décent facilitates a legally legitimate but morally suspect form of theft. The process involves a deception that leaves the victim suffering loss, with a consequential benefit accruing to the perpetrator. It pushes at the limits of legality and social acceptability whilst retaining the appearance of probity; a process that successfully works to sanction deceit and avoid retribution, legal or social. It is thereby free to contribute to a culture of creative opportunism and social cynicism. The vol décent offers a fresh perspective on La Comédie humaine, not simply as notion, process or phenomenon grounded etymologically and socioeconomically, but as heuristic capable of revealing fresh insights into Balzac’s position as narrator, observer and commentator on a Restoration society undergoing multiple transitions. Further, this thesis recognises the vol décent as a central feature of Balzac’s individual contribution to La Comédie humaine and theatre, informing both his vision and philosophy. As core heuristic, it contributes an innovative prospect that becomes a powerful tool probing the influential milieux of commercial speculation, business, theatre, private life and government institution. Within those spheres the vol décent reveals, using the operative lenses of theatricality, caricature, bureaucracy, architecture, deception and the law as facilitator of theft, a close and fresh view of socially sanctioned corruption. In the illumination of the notion of the vol décent and its capacity to inform of Balzac’s individual vision and philosophy, this research contributes an innovative insight into the complex, fundamental relationship between narrative representation, human nature, historical and environmental determinism. The open-endedness of the oxymoron, on which the phrase vol décent is based, accommodates transition, paradox and self-interest operating under a mask of legality. It questions whether the notion of the vol décent is in fact a systemic phenomenon or a basic trait of human nature.

description: We have conducted a new Arecibo survey for H I emission for 113 galaxies with broad-line (type 1) active galactic nuclei (AGNs) out to recession velocities as high as 35,000 km/s. The primary aim of the study is to obtain sensitive H I spectra for a well-defined, uniformly selected sample of active galaxies that have estimates of their black hole masses in order to investigate correlations between H I properties and the characteristics of the AGNs. H I emission was detected in 66 out of the 101 (65%) objects with spectra uncorrupted by radio frequency interference, among which 45 (68%) have line profiles with adequate signal-to-noise ratio and sufficiently reliable inclination corrections to yield robust deprojected rotational velocities. This paper presents the basic survey products, including an atlas of H I spectra, measurements of H I flux, line width, profile asymmetry, optical images, optical spectroscopic parameters, as well as a summary of a number of derived properties pertaining to the host galaxies. To enlarge our primary sample, we also assemble all previously published H I measurements of type 1 AGNs for which can can estimate black hole masses, which total an additional 53 objects. The final comprehensive compilation of 154 broad-line active galaxies, by far the largest sample ever studied, forms the basis of our companion paper, which uses the H I database to explore a number of properties of the AGN host galaxies.

description: Air pollution and congestion in the existing transport system have led various cities in Greece and abroad to promote pollution-free modes of transport such as cycling and walking. In recent years studies and research on pedestrian and bicycle networks have been carried out. However, relatively little research has been carried out to examine the behavior of pedestrians and bicycle users. The purpose of this Postgraduate Thesis is to examine the behavior of bicycle users as they approach and cross a marked intersection. Recording, analyzing and evaluating their behavior requires the identification of the data needs to record their behavior when they meet the traffic light, their gender, whether they wear a helmet, the lane they are traveling in and the cyclist's speed. The first chapter provides an introduction to the topic, with reference to the subject, the objectives and the methodology followed. The second chapter includes the literature review. The third chapter describes the design and implementation of measurements

description: Off-policy learning allows us to learn about possible policies of behavior from experience generated by a different behavior policy. Temporal difference (TD) learning algorithms can become unstable when combined with function approximation and off-policy sampling - this is known as the ''deadly triad''. Emphatic temporal difference (ETD($λ$)) algorithm ensures convergence in the linear case by appropriately weighting the TD($λ$) updates. In this paper, we extend the use of emphatic methods to deep reinforcement learning agents. We show that naively adapting ETD($λ$) to popular deep reinforcement learning algorithms, which use forward view multi-step returns, results in poor performance. We then derive new emphatic algorithms for use in the context of such algorithms, and we demonstrate that they provide noticeable benefits in small problems designed to highlight the instability of TD methods. Finally, we observed improved performance when applying these algorithms at scale on classic Atari games from the Arcade Learning Environment.

description: Pauli exclusion principle can lead to a supression of transport through double quantum dots, even if both quantum dots are connected by a resonant driving ac field. In this work, we study how this effect, known as spin blockade, can be removed by means of the influence of the driving field on the contacts to the leads.

description: We discuss the main myths related to the vacuum energy and cosmological constant, such as: ``unbearable lightness of space-time''; the dominating contribution of zero point energy of quantum fields to the vacuum energy; non-zero vacuum energy of the false vacuum; dependence of the vacuum energy on the overall shift of energy; the absolute value of energy only has significance for gravity; the vacuum energy depends on the vacuum content; cosmological constant changes after the phase transition; zero-point energy of the vacuum between the plates in Casimir effect must gravitate, that is why the zero-point energy in the vacuum outside the plates must also gravitate; etc. All these and some other conjectures appear to be wrong when one considers the thermodynamics of the ground state of the quantum many-body system, which mimics macroscopic thermodynamics of quantum vacuum. In particular, in spite of the ultraviolet divergence of the zero-point energy, the natural value of the vacuum energy is comparable with the observed dark energy. That is why the vacuum energy is the plausible candidate for the dark energy.

description: Με τη χρήση μαγνητικής τομογραφίας καρδιάς παράγονται ακολουθίες εικόνων (βίντεο) που περιέχουν έναν ή περισσότερους καρδιακούς κύκλους και ο εντοπισμός των στιγμιότυπων (frames) στα οποία απεικονίζεται η τελοδιαστολική και ο τελοσυστολική φάση (ED και ES frames) είναι μια απαραίτητη διαδικασία, η οποία αποτελεί το πρώτο βήμα με σκοπό τον υπολογισμό διαφόρων δεικτών, έχοντας ως τελικό στόχο τον έλεγχο της καλής λειτουργίας της. Ο εντοπισμός αυτός των ED και ES frames απαιτεί μεγάλη ακρίβεια, αλλά και χρόνο όταν γίνεται από ειδικό γιατρό. Στη παρούσα μελέτη υλοποιείται ένα πλήρως αυτοματοποιημένο σύστημα για την επίλυση του προβλήματος αυτού. Γίνεται χρήση νευρωνικών δικτύων και συγκεκριμένα ενός συνελικτικού νευρωνικού δικτύου (CNN) το οποίο κωδικοποιεί τη χωρική συσχέτιση των αλληλουχιών των εικόνων των MRI βίντεο καρδιάς, ενώ σε δεύτερο χρόνο χρησιμοποιείται ένα αναδρομικό νευρωνικό δίκτυο (RNN) το οποίο εκμεταλλεύεται τη χρονική συσχέτιση μεταξύ των διαδοχικών frame. Το σύστημα καταλήγει στην εκτέλεση παλινδρόμησης (regression) σε τιμές οι οποίες έχουν αντιστοιχιστεί στα δεδομένα σύμφωνα με μια συνάρτηση βελτιστοποιημένη πάνω στο συγκεκριμένο πρόβλημα. Το τελικό δίκτυο εκπαιδεύεται για ένα πλήθος παραδειγμάτων (δεδομένων εκπαίδευσης) και τελικά αποκτά την ικανότητα να εντοπίζει τα ED και ES frames σε άγνωστα προς αυτό δεδομένα με ακρίβεια
description: The use of cardiac magnetic resonance produces cine images containing one or more heart cycles and the identification of end diastolic and end systolic frames (ED and ES frames) is a necessary process that is the very first step of a pipeline for the calculation of various health indicators relative to heart operation. This identification is time consuming and requires high accuracy when performed by specialized personnel. In this master thesis, a fully automated system is implemented to address this problem. Neural networks are used, more specifically a convolution neural net (CNN) that encodes the spatial correlation between cine MRI image sequences, while at a later time, a recurrent neural network (RNN) is employed to exploit the temporal correlation among consecutive cine frames. The system ends up performing regression at values that are assigned to the data with the use of a function that is optimized on the particular problem. The final network is trained on a number of known data and eventually gains the ability to localize ED and ES frames on unknown data with accuracy

description: Evolutionary relationships between species are usually represented in phylogenies, i.e. evolutionary trees, which are a type of networks. The terminal nodes of these trees represent species, which are made of individuals and populations among which gene flow occurs. This flow can also be represented as a network. In this paper we briefly show some properties of these complex networks of evolutionary and ecological relationships. First, we characterize large scale evolutionary relationships in the Tree of Life by a degree distribution. Second, we represent genetic relationships between individuals of a Mediterranean marine plant, Posidonia oceanica, in terms of a Minimum Spanning Tree. Finally, relationships among plant shoots inside populations are represented as networks of genetic similarity.

Barriers to environmental education in British Columbia

Publisher: name: University of British Columbia

description: Based on a modified replication of Ham and Sewing's (1987) investigation, the purpose of this study was to identify and determine the relative importance of barriers which inhibit British Columbian public school teachers at the Grade eight, nine, and ten levels from conducting environmental education. Fifty-one junior secondary teachers from four school districts in the southwestern region of British Columbia were personally interviewed between April 1st and June 30, 1993. The four selected school districts can be classified and distinguished as representing three different kinds of areas: (1) urban-like regions, (2) nonconflict rural-like regions, and (3) regions immersed in environmental disputes and dependent primarily on one resource-based industry. Findings indicate that junior secondary school teachers identified the lack of environmental education instructional materials as the most important barrier. Other important logistical barriers to environmental education implementation included the lack of teaching and preparation time as well as lack of funding. Conceptual barriers consisted of teachers emphasizing only the cognitive elements of environmental education. In addition, despite believing that no special training is necessary for teaching environmental education, teachers still perceived the lack of knowledge about environmental education and natural science to be important barriers. Moreover, although most teachers possessed a positive attitude and believed that environmental education should be integrated throughout the curriculum at all grade levels, actual environmental education implementation in classrooms was limited. Lastly, recommendations for reducing environmental education barriers and enhancing future studies are proposed.

Production of GeV-scale heavy neutral leptons in 3-body decays. Comparison with the PYTHIA approach

description: Despite the undeniable success of the Standard Model of particle physics (SM), there are some phenomena that the SM can't explain. These phenomena indicate that the SM has to be modified. One of the possible ways to extend the SM is to introduce heavy neutral leptons (HNLs). To search for HNLs in intensity frontier experiments, one has to consider HNL production both in 2-body and 3-body decays of some mesons. We verified the possibility of using the parton level PYTHIA default matrix elements (without the form-factor formalism) to calculate HNL production in 3-body semileptonic decays of $B$ and $D$ mesons in the experimentally interesting mass range of the produced HNLs. We conclude that this approach is quite suitable for the estimation of the sensitivity region for HNLs in the intensity frontier experiments, provided one uses suitable parton level PYTHIA default matrix elements. Our study was driven by the usage of such an approximation by the SHiP collaboration. We conclude that in this case the parton level PYTHIA default matrix elements could have been chosen more appropriately.

description: We present theoretical evidence, based on total-energy first-principles calculations, of the existence of spin-polarized states well localized at and extended along the edges of bare zigzag boron nitride nanoribbons. Our calculations predict that all the magnetic configurations studied in this work are thermally accessible at room temperature and present an energy gap. In particular, we show that the high spin state, with a magnetic moment of 1 $μ_B$ at each edge atom, presents a rich spectrum of electronic behaviors as it can be controlled by applying an external electric field in order to obtain metallic $\leftrightarrow$ semiconducting $\leftrightarrow$ half-metallic transitions.

description: Nine point sources appeared within half an hour on a region within $\sim$ 10 arcmin of a red-sensitive photographic plate taken in April 1950 as part of the historic Palomar Sky Survey. All nine sources are absent on both previous and later photographic images, and absent in modern surveys with CCD detectors which go several magnitudes deeper. We present deep CCD images with the 10.4-meter Gran Telescopio Canarias (GTC), reaching brightness $r \sim 26$ mag, that reveal possible optical counterparts, although these counterparts could equally well be just chance projections. The incidence of transients in the investigated photographic plate is far higher than expected from known detection rates of optical counterparts to e.g.\ flaring dwarf stars, Fast Radio Bursts (FRBs), Gamma Ray Bursts (GRBs) or microlensing events. One possible explanation is that the plates have been subjected to an unknown type of contamination producing mainly point sources with of varying intensities along with some mechanism of concentration within a radius of $\sim$ 10 arcmin on the plate. If contamination as an explanation can be fully excluded, another possibility is fast (t $<0.5$ s) solar reflections from objects near geosynchronous orbits. An alternative route to confirm the latter scenario is by looking for images from the First Palomar Sky Survey where multiple transients follow a line.

description: Wasserbasierte Restaurierungsverfahren stehen im Verdacht, die Langzeitstabilität von Papieren, die optische Aufheller (engl. optical brightening agents, kurz OBAs) beinhalten, negativ zu beeinflussen. Grund dafür ist eine Farb- und Fluoreszenzveränderung, die bei Papieren mit OBAs im Bereich einer verso aufgebrachten Montierung auftreten. Es wird die These aufgestellt, dass durch das Eindringen von Wasser OBAs im Papier gelöst werden, wodurch der lichtbedingte Zerfall der Aufhellermoleküle katalysiert wird. Ziel der Masterarbeit ist es, die Eignung von etablierten wasserbasierten Restaurierungsverfahren an Papieren mit OBAs zu untersuchen. Hierfür werden drei wässrige Verfahren auf zwei Papieren mit OBAs angewendet und einer künstlichen Lichtalterung unterzogen. Da die Polarität von Wasser ausschlaggebend für das Schadensbild zu sein scheint, werden in den Testreihen ebenfalls zwei Alkohole geringerer Polarität getestet. Die Auswertung erfolgt optisch sowie quantitativ mittels digitaler Bildanalyse, Farbmessungen und Reflexionsmessungen der Probepapiere. Die Untersuchungen ergaben, dass die Farbstabilität der Papiere nach einer wässrigen Behandlung reduziert wird. Nach der Lichtalterung kommt es zu einer Verschiebung des Farbtons und Verringerung der Fluoreszenz im behandelten Areal. Als Grund dafür wird der beschleunigte Zerfall der OBAs erkannt. Das Schadensphänomen verstärkt sich mit steigender Polarität des Lösemittels und wird in seiner Intensität von der Papierzusammensetzung beeinflusst. Während die verringerte Fluoreszenz der Probepapiere bereits optisch sichtbar ist, lassen sich die Farbveränderungen ausschließlich messtechnisch dokumentieren.
