description: We present a new algorithm for computing the real radical of an ideal and, more generally, the-radical of, which is based on convex moment optimization. A truncated positive generic linear functional vanishing on the generators of is computed solving a Moment Optimization Problem (MOP). We show that, for a large enough degree of truncation, the annihilator of generates the real radical of. We give an effective, general stopping criterion on the degree to detect when the prime ideals lying over the annihilator are real and compute the real radical as the intersection of real prime ideals lying over. The method involves several ingredients, that exploit the properties of generic positive moment sequences. A new efficient algorithm is proposed to compute a graded basis of the annihilator of a truncated positive linear functional. We propose a new algorithm to check that an irreducible decomposition of an algebraic variety is real, using a generic real projection to reduce to the hypersurface case. There we apply the Sign Changing Criterion, effectively performed with an exact MOP. Finally we illustrate our approach in some examples.

description: Using the Submillimeter Array (SMA) we have imaged for the first time the 321.226 GHz, 10_{29}-9_{36} ortho-H2O maser emission. This is also the first detection of this line in the Cepheus A high-mass star-forming region. The 22.235 GHz, 6_{16}-5_{23} water masers were also observed with the Very Large Array 43 days following the SMA observations. Three of the nine detected submillimeter maser spots are associated with the centimeter masers spatially as well as kinematically, while there are 36 22 GHz maser spots without corresponding submillimeter masers. In the HW2 source, both the 321 GHz and 22 GHz masers occur within the region of ~1'' which includes the disk-jet system, but the position angles of the roughly linear structures traced by the masers indicate that the 321 GHz masers are along the jet while the 22 GHz masers are perpendicular to it. We interpret the submillimeter masers in Cepheus A to be tracing significantly hotter regions (600~2000 K) than the centimeter masers.

description: We show that the Quantum Spin Hall Effect, a state of matter with topological properties distinct from conventional insulators, can be realized in HgTe/CdTe semiconductor quantum wells. By varying the thickness of the quantum well, the electronic state changes from a normal to an "inverted" type at a critical thickness $d_c$. We show that this transition is a topological quantum phase transition between a conventional insulating phase and a phase exhibiting the QSH effect with a single pair of helical edge states. We also discuss the methods for experimental detection of the QSH effect.

description: Bilayer electron-hole systems, where carriers in one layer are electrons and carriers in the other are holes, have been actively investigated in recent years with the focus on Bose-Einstein condensation of excitons. This condensation is expected to occur when the layer separation d is much smaller than the interparticle distance r_sa_B within each layer. In this Brief Report, we argue for the existence of a state, Wigner supersolid, in which excitons are phase-coherent but form a Wigner crystal due to dipolar repulsion. We present the qualitative phase diagram of a bilayer system, and discuss properties and possible signatures of the Wigner supersolid phase.

The effects of light conditions from patchy natural canopies on the growth and morphology of white clover clones
Creators: name: Marcuvitz, Sheldon
Publisher: name: University of British Columbia
Year: 2009

description: In a community such as a pasture, the success of an individual plant might be affected by neighboring plants. One influence of neighbors on the environment of a plant is alteration of light conditions. Canopies in natural environments have only recently been recognized as heterogeneous in this regard, and responses of plants to alterations in light conditions under heterogeneous canopies are poorly understood. In this investigation, heterogeneity in canopy conditions experienced by white clover (Trifolium repens L.) in a pasture was acknowledged. Three natural canopy configurations were used to examine whether light conditions established by neighbors alter the growth and morphology of white clover clones. Live grass neighbors were used and at the same time, over one clover plant, patches of different light quality and/or quantity were provided. In the first set of experiments, light reflected from grass neighbors was provided simultaneously with direct light. There were. no consistent effects on white clover growth and morphology, but there was evidence of phototropic movement of plant structures, which became located in positions that might minimize the effects of grasses on more permanent features of the clones. In the second set of experiments, shade from three different species of grass was presented to different clover clones for parts of each day, with full sun around noon. The canopies reduced overall growth and branching of clones, while increasing length of, and biomass allocation to, petioles. Lolium perenne had different effects compared to Holcus lanatus or Dactylis glomerata, but between the latter two species, no differences were detected. In the final set of experiments, two interconnected portions of white clover clones, the apical and basal regions of a primary stolon, were subjected to local canopies. Basal region response was examined for independence from apical region conditions and vice versa. Basal regions responded to apical conditions only when they were themselves shaded, while apical regions responded to basal conditions regardless of their local illumination. The ways in which plants respond to neighboring vegetation are complex, and difficulty exists in interpreting plant morphology in terms that are ecologically relevant. If we could identify advantages to particular strategies or responses, and then selectively control plant performance, we might be able to improve our use of plants through more efficient production and management schemes.

Year: 2007
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: A general overview of the measurement of long-range multiplicity correlations measured by the STAR experiment in Au+Au collisions at RHIC is presented. The presence of long-range correlations can provide insight into the early stages, and the type of matter produced in, these collisions. These measurements have been made in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 and 62.4 GeV. These results indicate a relatively large long-range correlation is produced in Au+Au collisions compared to a {\it pp} baseline at $\sqrt{s_{NN}}$ = 200 GeV. A weaker long-range correlation is seen as a function of incident energy. Further, comparison of the onset of the long-range correlation to the calculated percolation density parameter at $\sqrt{s_{NN}}$ = 200 GeV is presented.

description: We report on finite-size exact-diagonalization calculations in a Hilbert space defined by the continuum-model flat moiré bands of magic angle twisted bilayer graphene (MATBG). For moiré band filling $3>|ν|>2$, where superconductivity is strongest, we obtain evidence that the ground state is a spin ferromagnet. Near $|ν|=3$, we find Chern insulator ground states that have spontaneous spin, valley, and sublattice polarization, and demonstrate that the anisotropy energy in this order-parameter space is strongly band-filling-factor dependent. We emphasize that inclusion of the remote band self-energy is necessary for a reliable description of MATBG flat band correlations.

Επιπλέον, η έρευνα στοχεύει στην ανάλυση των παραγόντων που επηρεάζουν την αποδοτικότητα των Συνεταιρισμών. Αρχικά, συγκεντρώθηκαν τα οικονομικά στοιχεία από 14 Ενώσεις Αγροτικών Συνεταιρισμών και 14 Συνεταιριστικές Επιχειρήσεις για τα έτη 2006 – 2010. Τα στοιχεία αυτά επεξεργάστηκαν με το πρόγραμμα SPSS και προέκυψαν κάποια αποτελέσματα. Οι Συνεταιριστικές Επιχειρήσεις εμφανίζουν υψηλότερα επίπεδα αποδοτικότητας από τους Αγροτικούς Συνεταιρισμούς της χώρας καθώς διαθέτουν μια πιο ικανή διοίκηση η οποία επιτυγχάνει υψηλές πωλήσεις. Από τον υπολογισμό του υποδείγματος της αποδοτικότητας βρέθηκε πως ο χρηματοοικονομικός κίνδυνος, ο επιχειρηματικός κίνδυνος και η ρευστότητα επηρεάζουν θετικά την αποδοτικότητα των Αγροτικών Συνεταιρισμών ενώ αρνητικά επηρεάζεται από τα έτη λειτουργίας και το ρυθμό ανάπτυξης. Από την άλλη, η αποδοτικότητα των Συνεταιριστικών Επιχειρήσεων επηρεάζεται θετικά από τη ρευστότητα και τα έτη λειτουργίας, ενώ αρνητική επίδραση φαίνεται πως εμφανίζουν ο ρυθμός ανάπτυξης, ο επιχειρηματικός και χρηματοοικονομικός κίνδυνος. Οι Αγροτικοί Συνεταιρισμοί στην Ελλάδα για να αυξήσουν τα επίπεδα της απόδοσης τους θα πρέπει να εφαρμόσουν στρατηγικές ανάπτυξης παρόμοιες με αυτές των επιχειρήσεων.
description: The main purpose of this paper is to analyze and compare the efficiency of Agricultural Cooperatives and Cooperative Enterprises of Greece. In addition, this paper aims to analyze the factors that affect the efficiency of Cooperatives. First of all, we collect the economic data from 14 Unions of Agricultural Cooperatives and 14 cooperative enterprises for the years 2006 – 2010. We elaborate them with the program SPSS and we conclude to some results. The Cooperative Enterprises featured with higher levels of profitability than the Agricultural Cooperatives of the country, as they have a more capable administration, which achieves high sales. By calculating the efficiency model it seems that financial risk, business risk and liquidity affect the profitability of Agricultural Cooperatives positively, although years and growth rate affect the efficiency negatively. On the other hand, the efficiency of Cooperative Enterprises is affected positively by the liquidity and the years of operation, while a negative effect seems to show the growth rate, the business and the financial risk. Agricultural Cooperatives in Greece have to implement development strategies like Agricultural Enterprises to raise their performance levels.

description: Direct imaging of exoplanets is limited by bright quasi-static speckles in the point spread function (PSF) of the central star. This limitation can be reduced by subtraction of reference PSF images. We have developed an algorithm to construct an optimized reference PSF image from a set of reference images. This image is built as a linear combination of the reference images available and the coefficients of the combination are optimized inside multiple subsections of the image independently to minimize the residual noise within each subsection. The algorithm developed can be used with many high-contrast imaging observing strategies relying on PSF subtraction, such as angular differential imaging (ADI), roll subtraction, spectral differential imaging, reference star observations, etc. The performance of the algorithm is demonstrated for ADI data. It is shown that for this type of data the new algorithm provides a gain in sensitivity by up to a factor 3 at small separation over the algorithm used in Marois et al. (2006).

description: Mesh-free methods have significant potential for simulations of flows in complex geometries, with the difficulties of domain discretisation greatly reduced. However, many mesh-free methods are limited to low order accuracy. In order to compete with conventional mesh-based methods, high order accuracy is essential. The Local Anisotropic Basis Function Method (LABFM) is a mesh-free method introduced in King et al., J. Comput. Phys. 415:109549 (2020), which enables the construction of highly accurate difference operators on disordered node discretisations. Here, we introduce a number of developments to LABFM, in the areas of basis function construction, stencil optimisation, stabilisation, variable resolution, and high order boundary conditions. With these developments, direct numerical simulations of the Navier Stokes equations are possible at extremely high order (up to 10th order in characteristic node spacing internally). We numerically solve the isothermal compressible Navier Stokes equations for a range of geometries: periodic and channel flows, flows past a cylinder, and porous media. Excellent agreement is seen with analytical solutions, published numerical results (using a spectral element method), and experiments. The potential of the method for direct numerical simulations in complex geometries is demonstrated with simulations of subsonic and transonic flows through an inhomogeneous porous media at pore Reynolds numbers up to Re=968.

description: Mahi-mahi (Coryphaena hippurus) are a highly migratory pelagic fish, but little is known about what environmental factors drive their broad distribution. This study examined how temperature influences aerobic scope and swimming performance in mahi. Mahi were acclimated to four temperatures spanning their natural range (20, 24, 28, and 32°C; 5-27 days) and critical swimming speed (Ucrit), metabolic rates, aerobic scope, and optimal swim speed were measured. Aerobic scope and Ucrit were highest in 28°C-acclimated fish. 20°C-acclimated mahi experienced significantly decreased aerobic scope and Ucrit relative to 28°C-acclimated fish (57 and 28% declines, respectively). 32°C-acclimated mahi experienced increased mortality and a significant 23% decline in Ucrit, and a trend for a 26% decline in factorial aerobic scope relative to 28°C-acclimated fish. Absolute aerobic scope showed a similar pattern to factorial aerobic scope. Our results are generally in agreement with previously observed distribution patterns for wild fish. Although thermal performance can vary across life stages, the highest tested swim performance and aerobic scope found in the present study (28°C), aligns with recently observed habitat utilization patterns for wild mahi and could be relevant for climate change predictions.

description: The present survey deals with both the multicultural education conditions, which teach how “we” and the “others can harmoniously live together in the same environment, and the matter of lifelong learning and particularly the one that takes place in Second Chance Schools. It indicates that the respect to the different “others” and the normal socialization (in every period of a person’s life) are elements that cannot be separated from the concept of school. That fact we wanted to study by carrying out the present research involving foreigners who studied in Second Chance Schools during their serving in Greek prisons.

description: Watson-Crick (WK) automata serve as the reasonable models for DNA computing. It is the goal of this thesis to introduce a Watson-Crick monadic second-order logic (WKMSO logic) and to describe any language accepted from a WK automaton with a sentence from this logic. We firstly refer to some basic notions, a short historical reference about DNA computing, and a brief description of the basic structure of DNA itself. Furthermore, we describe a sequence of DNA-based biological operations used for DNA processing. These techniques are basic tools for the experiments in DNA computing, we describe below. We also describe Adleman's experiment and the 3-SAT problem and we refer to the formalization of DNA bonds and the mathematical notion describing the Watson-Crick complementarity. We finally mention a vectorial formalism of the notions of DNA single, double, and partial double strand. Then we cite the model of (nondeterministic) WK automata and their variations. Furthermore, we introduce a type of homomorphisms respecting the complementarity of WK automata and we show that the class of WK-recognizable languages is closed under this type of homomorphisms. Subsequently we introduce our WKMSO logic and we show that every language which is accepted by a WK automaton is definable by a sentence in WKMSO logic. Finally we make a brief reference of advantages and limitations of DNA computing, conclusions, and open problems for further research.

description: Magic-angle twisted bilayer graphene exhibits a panoply of many-body phenomena that are intimately tied to the appearance of narrow and well-isolated electronic bands. The microscopic ingredients that are responsible for the complex experimental phenomenology include electron-electron (phonon) interactions and non-trivial Bloch wavefunctions associated with the narrow bands. Inspired by recent experiments, we focus on two independent quantities that are considerably modified by Coulomb interaction driven band renormalization, namely the density of states and the minimal spatial extent associated with the Wannier functions. First, we show that a filling-dependent enhancement of the density of states, caused by band flattening, in combination with phonon-mediated attraction due to electron-phonon umklapp processes, increases the tendency towards superconducting pairing in a range of angles around magic-angle. Second, we demonstrate that the minimal spatial extent associated with the Wannier functions, which contributes towards increasing the superconducting phase stiffness, also develops a non-trivial enhancement due to the interaction induced renormalization of the Bloch wavefunctions. While our modeling of superconductivity assumes a weak electron-phonon coupling and does not consider many of the likely relevant correlation effects, it explains simply the experimentally observed robustness of superconductivity in the wide range of angles that occurs in the relevant range of fillings.

description: The study of the interaction of gestational pyelonephritis with pregnancy is relevant due to the high percentage of obstetric complications, negative perinatal outcomes and severe diseases in newborns, which emphasizes the medical and socio-economic importance of the problem. In chronic pyelonephritis, the course of pregnancy is complicated by iron deficiency anemia (35-70%), premature termination of pregnancy at various times (15-20%), and chronic placental insufficiency (30-35%), gestosis (35-70%). In 30-40% of cases, complications such as chronic uterine hypoxia (30-40%), fetal infection (20-30%) and growth retardation (12-15%) occur. Chronic pyelonephritis significantly impairs the ability of pregnant women to adapt to newborns and increases the risk of early neonatal mortality.

description: Given the high incidence of perinatal complications in women with gestational diabetes mellitus (GDM), an effective algorithm for diagnosing and treating this disease is necessary. We analyzed the characteristics of the course and outcomes of pregnancy in 500 women with GDM, in whom new clinical recommendations for the diagnosis and treatment of gestational diabetes mellitus were used. The comparison group consisted of 100 women with GDM (criteria by V. G. Baranov, 1977). Analysis of the results is necessary to optimize the management tactics of this group of patients.

description: Στόχος της παρούσας έρευνας ήταν η διερεύνηση του φαινομένου της επιθετικότητας, φανερής και επιθετικότητας σχέσεων, στο νηπιαγωγείο καθώς και η διερεύνηση της σύνδεσής του με τη λειτουργικότητα της οικογένειας και τις ψυχολογικές δυσκολίες και δυνατότητες των παιδιών. Για τη επίτευξη του στόχου αυτού χρησιμοποιήθηκαν δεδομένα τόσο από τις μητέρες, όσο και από τους πατέρες και τις νηπιαγωγούς των παιδιών, τα οποία έδιναν πληροφορίες για τις αντιλήψεις τους για τους παράγοντες που προαναφέρθηκαν. Στο δείγμα συμμετείχαν 123 μητέρες, 110 πατέρες και 16 νηπιαγωγοί οι οποίοι κλήθηκαν να εκτιμήσουν τα επίπεδα επιθετικότητας των παιδιών, τις ψυχολογικές τους δυσκολίες και τις θετικές κοινωνικές τους συμπεριφορές, ενώ από τους γονείς ζητήθηκε επιπλέον να συμπληρώσουν ένα ερωτηματολόγιο σχετικά με τη λειτουργικότητα της οικογένειάς τους. Η επιθετικότητα βρέθηκε να συνδέεται θετικά με τις ψυχολογικές δυσκολίες και αρνητικά με τις θετικές κοινωνικές συμπεριφορές των παιδιών και για τους τρεις αξιολογητές (μητέρες, πατέρες, νηπιαγωγούς). Επιπλέον, βρέθηκε στατιστικώς σημαντική επίδραση του φύλου στην επιθετικότητα και στις δύο διαστάσεις της. Τέλος, βρέθηκαν αρκετές ομοιότητες στις αντιλήψεις των γονέων μεταξύ τους αλλά και των γονέων με τις νηπιαγωγούς για την επιθετικότητα, με εξαίρεση τη φανερή επιθετικότητα όπου οι νηπιαγωγοί δήλωσαν χαμηλότερη συχνότητα τέτοιου τύπου περιστατικών.
description: The objective of this research was to investigate the phenomenon of aggression, overt aggression and relational aggression in kindergarten and to explore its association with family functioning and psychological difficulties and strenghts of children. To achieve this goal data from both mothers, fathers and kindergarten children were used, which gave information on their perceptions of the factors mentioned above. The participants were 123 mothers, 110 fathers and 16 kindergarten teachers who were asked to assess aggression levels of children, the psychological difficulties and prosocial behaviors, while parents were also asked to complete a questionnaire about their family functioning. Aggression was found to be positively associated with psychological difficulties and negatively associated with the prosocial behaviors of children for all three evaluators (mothers, fathers, kindergarten teachers). Moreover, gender was found to have a statistically significant effect on aggression and its two dimensions. Finally, several similarities in parents and kindergarten teachers’ perceptions for aggression were found, with the exception of overt aggression, where kindergarten teachers claimed lower frequency of this type of incidents compared to parents.

Captain Cook at Nootka Sound and some questions of colonial discourse
Creators: name: Currie, Noel Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation examines the workings of various colonial discourses in the texts of Captain James Cook’s third Pacific voyage. Specifically, it focusses on the month spent at Nootka Sound (on the west coast of Vancouver Island) in 1778. The textual discrepancies between the official 1784 edition by Bishop Douglas, A Voyage to the Pacific Ocean, and J.C. Beaglehole’ s scholarly edition of 1967, The Voyage of the Resolution and Discovery 1776-1780, reveal that Cook’s Voyages present not an archive of European scientific and historical knowledge about the new world but the deployment of colonial discourses. Examining this relatively specific moment as discourse expands a critical sense of the importance of Cook’s Voyages as cultural documents, for the twentieth century as well as for the eighteenth. Chapters One and Two consider the mutually interdependent discourses of aesthetics and science: based upon assumptions of “objectivity,’ they distance the observing subject from the object observed, in time as well as in space. Chapter Three traces the development of the trope of cannibalism and argues that this trope works in the editions of Cook’s third voyage to further distance the Nootka from Europeans by textually establishing what looked like savagery. Chapter Four examines the historical construction of Cook as imperial culture hero, for eighteenth-century England, Western Europe, and the settler cultures that followed in his wake. Taken separately and together, these colonial discourses are employed in the accounts of Cook’s month at Nootka Sound to justify and rationalise England’s claim to appropriation of the territory. The purpose of these colonial discourses is to fix meaning and to present themselves as natural; the purpose of my dissertation is to disrupt such constructions. I therefore disrupt my own discourse with a series of digressions, signalled by a different typeface. They allow me to pursue lines of thought related tangentially to the main arguments and thus to investigate the wider concerns of the culture that produced Cook’s voyages, They also give me the opportunity to interrogate my own critical methodology and assumptions. Ultimately I aim not to create another, more convincing construction of Cook and his month at Nootka Sound, but to illuminate a cultural process, a way of making meaning that is part of his intellectual legacy.

description: We have experimentally demonstrated how two beams of light separated by an octave in frequency can become entangled after their interaction in a second-order nonlinear medium. The entangler consisted of a nonlinear crystal placed within an optical resonator that was strongly driven by coherent light at the fundamental and second-harmonic wavelengths. An inter-conversion between the fields created quantum correlations in the amplitude and phase quadratures, which were measured by two independent homodyne detectors. Analysis of the resulting correlation matrix revealed a wavefunction inseparability of 0.74(1) < 1 thereby satisfying the criterion of entanglement.

description: Over the last 4 years we have designed and implemented the Genomics Virtual Laboratory (GVL: http://genome.edu.au) as a middleware layer of machine images, cloud management tools, and online services that enable researchers to build arbitrary sized Galaxy compute clusters on demand, pre-populated with fully configured bioinformatics tools, reference datasets and workflow and visualisation options. The platform is flexible in that users can conduct analyses through multiple web-based (Galaxy, RStudio, IPython Notebook) or command-line interfaces, and add/remove compute nodes and data resources as required. Best practice tutorials and protocols provide a path from introductory training to practice. The GVL is available on the OpenStack-based Australian Research Cloud (http://nectar.org.au) and the Amazon Web Services cloud via a dedicated web-based launcher application (http://launch.genome.edu.au).
