description: This paper provides an outline of a formal approach that we are developing for modelling Virtual Organisations (VOs) and their Breeding Environments (VBEs). We propose different levels of representation for the functional structures and processes that VBEs and VOs involve, which are independent of the specificities of the infrastructures (organisational and technical) that support the functioning of VBEs. This allows us to reason about properties of tasks performed within VBEs and services provided through VOs without committing to the way in which they are implemented.
THE KOIDE FORMULA PROOF OF THE HEXAGONAL BONDING OF NEUTRONS AND PROTONS IN THE ATOMIC NUCLEUS

description: Redrawing the atomic nucleus into a crystalline structure made of hexagonal proton-neutron relationships where the elegance, the structural simplicity of that crystalline structure of the atomic nucleus, gave new and promising insights into its inner workings. After analysis of the input of the numerical data of the constituent parts of the protons and the neutrons in the Koide formula, it seems a reasonable conclusion that there is a clear and real physical connection between the hexagonal structure of the atomic nucleus and that Koide formula, which in turn strengthens the theorem of the hexagonal structure of the atomic nucleus and at the same time also gives a different weight to the value of the Koide formula itself, away from the claim by some that it is purely numerology. At the same time, new insights emerged that pushed past assumptions into the background
Metric Lagrangians with two propagating degrees of freedom

description: There exists a large class of generally covariant metric Lagrangians that contain only local terms and describe two propagating degrees of freedom. Trivial examples can be be obtained by applying a local field redefinition to the Lagrangian of general relativity, but we show that the class of two propagating degrees of freedom Lagrangians is much larger. Thus, we exhibit a large family of non-local field redefinitions that map the Einstein-Hilbert Lagrangian into ones containing only local terms. These redefinitions have origin in the topological shift symmetry of BF theory, to which GR is related in Plebanski formulation, and can be computed order by order as expansions in powers of the Riemann curvature. At its lowest non-trivial order such a field redefinition produces the (Riemann)^3 invariant that arises as the two-loop quantum gravity counterterm. Possible implications for quantum gravity are discussed.

description: We propose neural-symbolic integration for abstract concept explanation and interactive learning. Neural-symbolic integration and explanation allow users and domain-experts to learn about the data-driven decision making process of large neural models. The models are queried using a symbolic logic language. Interaction with the user then confirms or rejects a revision of the neural model using logic-based constraints that can be distilled into the model architecture. The approach is illustrated using the Logic Tensor Network framework alongside Concept Activation Vectors and applied to a Convolutional Neural Network.

description: Earth's bow shock is known to produce non-thermal electrons which are generally observed as a `spike' in their flux profile. Here, in this paper, we present an analysis of electron and whistler wave properties for a quasi-perpendicular shock crossing that is supercritical, but subcritical to the so-called whistler critical Mach number, M$^w_{\rm crit}$, above which whistler waves cannot propagate upstream. We have found that the amplitudes of whistler waves increased exponentially as a function of time prior to the shock encounter, while the suprathermal ($>$ 2 keV) electron flux similarly increased with time, although with differing $e$-folding time scales. Comparison of the electron energy spectrum measured within the ramp with predictions from diffusive shock acceleration theory was poor, but the variation of pitch angle distribution showed scattering of non-thermal electrons in the upstream region. While not finding a specific mechanism to account for the electron diffusion, we suggest that the whistlers seen probably account for the differences observed between this `gradual' event and the `spike' events seen at shocks with no upstream whistlers.

The relationship between auditory figure-ground perception and academic achievement in open area and self-contained classrooms
Creators: name: Brown, Cheryl Ann
Publisher: name: University of British Columbia
Year: 2010

description: This study was designed to investigate the effects of two different learning environments on the achievement of children who were suspected of having auditory figure-ground perception problems. Comparison of the noise levels in the three open area and three self-contained classrooms used in the study revealed that the open areas were consistently louder than the self-contained classes but the differences were only statistically significant in the mornings. Because of these expected differences in noise level, it was hypothesized that the more difficulty grade one children in open areas had with auditory figure-ground perception as measured by the noise subtest of the Goldman-Fristoe-Woodcock Test of Auditory Discrimination, the lower their achievement scores would be on the Cooperative Primary Tests. This relationship was not expected to be found in grade one children who received their first year of formal instruction in self-contained classrooms. A stepwise multiple regression analysis was used to test this hypothesis with Wide Range Achievement Test scores (administered in the Fall) as covariates and three subtests of the Cooperative Primary Test scores (administered in the Spring) as dependent variables. Although a trend in the expected direction was found, the results were not statistically significant (⍺ = .05). Therefore, it could not be concluded that children with auditory figure-ground perception problems were more appropriately placed in self-contained classrooms.

description: In the context of holography, we analyse aspects of supersymmetric geometries based on two-dimensional orbifolds known as spindles. By analysing spin$^c$ spinors on a spindle with an azimuthal rotation symmetry we show that under rather general conditions there are just two possibilities, called the `twist' and the `anti-twist', which are determined by the quantized magnetic flux through the spindle. A special case of the twist is the standard topological twist which is associated with constant and chiral spinors. We construct solutions of $D=5$ and $D=4$ STU gauged supergravity theories that are dual to D3-branes and M2-branes wrapping spindles, respectively, which realize both the anti-twist, as seen before, but also the twist. For the wrapped D3-brane solutions we reproduce the central charge of the gravity solution from the dual field theory by analysing the anomaly polynomial of $\mathcal{N}=4$ SYM theory. We also discuss M5-branes wrapped on spindles both from a gravity and a field theory point of view.

description: The influence of the geometric phase on a Bell measurement, as proposed by Bertlmann et al. in [Phys. Rev. A 69, 032112 (2004)], and expressed by the Clauser-Horne-Shimony-Holt (CHSH) inequality, has been observed for a spin-path entangled neutron state in an interferometric setup. It is experimentally demonstrated that the effect of geometric phase can be balanced by a change in Bell angles. The geometric phase is acquired during a time dependent interaction with two radio-frequency (rf) fields. Two schemes, polar and azimuthal adjustment of the Bell angles, are realized and analyzed in detail. The former scheme, yields a sinusoidal oscillation of the correlation function S, dependent on the geometric phase, such that it varies in the range between 2 and 2\sqrt{2} and, therefore, always exceeds the boundary value 2 between quantum mechanic and noncontextual theories. The latter scheme results in a constant, maximal violation of the Bell-like-CHSH inequality, where S remains 2\sqrt2 for all settings of the geometric phase.

Intrinsic properties of the bars formed by the bar instability in flat stellar discs
Creators: name: Hozumi, Shunsuke
Publisher: name: arXiv
Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The properties of the bars formed by the bar instability are examined for flat stellar discs. The initial mass models chosen are Kuzmin--Toomre discs, for which two types of exact equilibrium distribution function (DF) are employed in order to realize different distributions of Toomre's $Q$ values along the radius. First, the most linearly unstable, global two-armed modes (MLUGTAMs) of these disc models are determined by numerically solving the linearized collisionless Boltzmann equation. Next, we carry out $N$-body simulations whose models are constructed from the DFs adopted above. The latter simulations unravel that the MLUGTAMs corresponding to those obtained from the former modal calculations are excited in the early phases of evolution, finally being deformed into bars in the nonlinear regime by the bar instability. We show that for simulated bars, the length increases and the axis ratio, in essence, decreases as the amplitude increases. These correlations are almost similar to those of the observed bars. In addition, we find that these bar properties are tightly correlated with the initial typical $Q$ value, irrespective of the DF. In conclusion, a disc with a smaller typical $Q$ value produces a bar which is smaller in amplitude, shorter in length and rounder in shape. This finding might suggest that the Hubble sequence for barred galaxies is the sequence of decreasing $Q$ from SBa to SBc or SBd. The implied correlations between the initial typical $Q$ value and each of the bar properties are discussed on the basis of the characteristics of the MLUGTAMs.

description: We study a one-dimensional model of free fermions with $\mathfrak{gl}(1|1)$ supersymmetry and demonstrate how non-diagonal boundary conditions can be incorporated into the framework of the graded Quantum Inverse Scattering Method (gQISM) by means of \emph{super matrices} with entries from a superalgebra. For super hermitian twists and open boundary conditions subject to a certain constraint, we solve the eigenvalue problem for the super transfermatrix by means of the graded algebraic Bethe ansatz technique (gABA) starting from a fermionic coherent state. For generic boundary conditions the algebraic Bethe ansatz can not be applied. In this case the spectrum of the super transfer matrix is obtained from a functional relation.

description: The neutron star properties are generally determined by the equation of state of $β$-equilibrated dense matter. In this work, we consider the interaction of fermionic dark matter (DM) particles with the nucleons via Higgs exchange and investigate its effect on the neutron star properties with the relativistic mean-field model equation of state coupled with DM. We deduce that DM significantly affects the neutron star properties, such as considerably reduce the maximum mass of the star, which depends on the percentage of the DM considered inside the neutron star. The tidal Love numbers both for electric and magnetic cases and surficial Love numbers are also studied for DM admixed NS. It is observed that the magnitude of tidal and surficial Love numbers increase with more DM percentage. Further, we point out that post-Newtonian tidal corrections to gravitational waves decreased by increasing DM percentage. Also, the DM effect on the GW signal is significant during the late inspiral and merger stages of binary evolution for GW frequencies >500 Hz.

description: The production of dark matter particles from confining dark sectors may lead to many novel experimental signatures. Depending on the details of the theory, dark quark production in proton-proton collisions could result in semivisible jets of particles: collimated sprays of dark hadrons of which only some are detectable by particle collider experiments. The experimental signature is characterised by the presence of reconstructed missing momentum collinear with the visible components of the jets. This complex topology is sensitive to detector inefficiencies and mis-reconstruction that generate artificial missing momentum. With this work, we propose a signal-agnostic strategy to reject ordinary jets and identify semivisible jets via anomaly detection techniques. A deep neural autoencoder network with jet substructure variables as input proves highly useful for analyzing anomalous jets. The study focuses on the semivisible jet signature; however, the technique can apply to any new physics model that predicts signatures with anomalous jets from non-SM particles.

description: It is well known that thermally pulsing Asymptotic Giant Branch stars with low mass play a relevant role in the chemical evolution. They have synthesized about 30% of the galactic carbon and provide an important contribution to the nucleosynthesis of heavy elements (A>80). The relevant nucleosynthesis site is the He-rich intermediate zone (less than 10^{-2} Msun), where alpha(2alpha,gamma)12C reactions and slow neutron captures on seed nuclei essentially iron) take place. A key ingredient is the interplay between nuclear processes and convective mixing. It is the partial overlap of internal and external convective zones that allows the dredge-up of the material enriched in C and heavy elements. We review the progresses made in the last 50 years in the comprehension of the s process in AGB stars, with special attention to the identification of the main neutron sources and to the particular physical conditions allowing this important nucleosynthesis.

Construction and validation of a programmed instruction booklet : methods of adult education
Creators: name: Betts, Diane Elmira
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis was to construct and validate a programmed instruction booklet for the use of university students studying to become adult educators. The concept of methods of adult education and the classification scheme for methods as devised by Dr. C. Verner were used as course content. The branching or intrinsic model was selected and a criterion test and frames were constructed. The booklet was empirically tested through a developmental test and two field tests. Sixty-two students enrolled in three classes of Education 412, during the 1974 summer and 1975 winter sessions at The University of British Columbia, participated in the validation procedure. The developmental test group consisted of twelve students who sat with the programmer, one at a time, as they studied the booklet and completed a pre and post criterion test. The field test was designed as a course take home assignment and students were responsible for returning written answers to a pre and post criterion test. Ten students volunteered to study the booklet during the first field test. The second field test assigned twenty students to a pre and post criterion test only control group design and twenty students to an experimental group design who studied the booklet and completed a pre and post criterion test. Analysis of the data following the developmental and first field tests revealed many areas of weakness in the booklet frames and in the criterion test. Consequently many major revisions were made to both. Examination of the data following the second field test indicated the booklet met the standards of an effective teaching program.

Ένας ζυθοποιός έχει την ανάγκη να γνωρίζει όλα τα στάδια της παραγωγής του ζύθου, από την πορεία της πρώτης ύλης (κριθάρι και στην συνέχεια βύνη κριθαριού) έως και το έτοιμο συσκευασμένο προϊόν. Σκοπός της μελέτης είναι η ανάδειξη του ελληνικού κριθαριού και σιταριού, η καλλιέργειά τους και η διαφοροποίηση που προκύπτει στην πρώτη ύλη σε περίπτωση διαφορετικού τρόπου καλλιέργειας. Για τους σκοπούς του πειράματος εγκαταστάθηκαν καλλιέργειες κριθαριού και σιταριού στις περιοχές του Προφήτη Ηλία Βοιωτίας και την Ελάτεια Φθιώτιδος σε έκταση 48 στρέμματα για το στάρι και 300 για το κριθάρι. Στόχος ήταν η παρακολούθηση των καλλιεργειών σε όλα τα στάδια (από την σπορά μέχρι και το θερισμό), ο εντοπισμός διαφορών κατά την διαδικασία καλλιέργειας και πως οι διαφορές στην καλλιέργεια επηρεάζουν το τελικό προϊόν. Κατά την συγκομιδή συλλέχθηκαν δείγματα από όλα τα αγροτεμάχια, ταξινομήθηκαν, παρατηρήθηκαν τα μακροσκοπικά τους χαρακτηριστικά και υπολογίστηκαν η υγρασία, το εκατολιτρικό βάρος, το βάρος χιλίων κόκκων, η ευαισθησία στο νερό – η βλαστική τους ικανότητα. Στην συνέχεια, ακολούθησε στατιστική επεξεργασία των αποτελεσμάτων με ένα πρόγραμμα στατιστικής που ονομάζεται MiniTub, με σκοπό την ανάδειξη του καταλληλότερου αγροτεμαχίου – προϊόντος για την παραγωγή ζύθου. Τα αποτελέσματα έδειξαν πως η επέμβαση την κατάλληλη χρονική στιγμή στις καλλιέργειες είναι σημαντική και παρέχει την δυνατότητα ανταγωνισμού σε ποικιλίες που θεωρούνται ανεπαρκής. Συνεπώς, ποικιλίες που θεωρούνται ακατάλληλες για βυνοποίηση – ζυθοποίηση, με γνώμονα τις σωστές καλλιεργητικές τεχνικές μπορούν να αποδώσουν καρπούς με υψηλή ικανότητα τροποποίησης σε βύνη.

description: We study synchronization of non-diffusively coupled map networks with arbitrary network topologies, where the connections between different units are, in general, not symmetric and can carry both positive and negative weights. We show that, in contrast to diffusively coupled networks, the synchronous behavior of a non-diffusively coupled network can be dramatically different from the behavior of its constituent units. In particular, we show that chaos can emerge as synchronized behavior although the dynamics of individual units are very simple. Conversely, individually chaotic units can display simple behavior when the network synchronizes. We give a synchronization criterion that depends on the spectrum of the generalized graph Laplacian, as well as the dynamical properties of the individual units and the interaction function. This general result will be applied to coupled systems of tent and logistic maps and to two models of neuronal dynamics. Our approach yields an analytical understanding of how simple model neurons can produce complex collective behavior through the coordination of their actions.

description: We analyze the uncertainties introduced in the determination of the neutron star matter proton fraction, in a range of densities close to the saturation density, if the cold $β$-equilibrium neutron star matter equation of state (EoS) is known. In particular, we discuss the effect of neglecting the muon contribution and of considering that the energy density of nuclear matter is well described by taking only terms until second order in the proton-neutron asymmetry. It is shown that two types of uncertainties may be associated with the extraction of the symmetry energy from the $β$-equilibrium equation of state: an overestimation if terms above the parabolic approximation on the asymmetry parameter are neglected, or an underestimation if the muon contribution is not considered. The effect of the uncertainty on the symmetric nuclear matter EoS on the determination of the proton fraction is discussed. It could be shown that the neutron star mass-radius curve is sensitive to the parabolic approximation on the asymmetry parameter.

The effects of teacher-made and pupil-made simulation games on student attitudes toward social studies
Creators: name: Tiles, Alice Durana
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to test the effects of teacher-made and pupil-made simulation games on student attitudes toward social studies. A sample of seventy grades four and five students was randomly assigned to a control group, a teacher-made-simulation treatment group or a pupil-made-simulation treatment group. The control treatment group was instructed through the analytic approach while the teacher-made-simulation treatment group was instructed through the use of simulation games developed by the researcher. In the pupil-made-simulation treatment, the students developed and played simulation games within the classroom. The same objectives and instructional data were employed in each treatment. The researcher developed this unit following the procedures utilized in recent curriculum development practice. The inquiry processes incorporated in this unit were adapted from the analytic and integrative modes of inquiry. The control treatment utilized primarily the analytic mode while the teacher-made and pupil-made-simulation treatments employed primarily the integrative mode. The researcher administered the three treatments consecutively with each treatment consisting of fourteen instructional periods. Student attitudes toward social studies were evaluated by means of a paired-comparison rating scale. A pre-test was administered five months prior to the study and a post-test was administered one week after the administration of each treatment. A modified paired comparison rating scale was given as a delayed post-test to the control and teacher-made-simulation treatment groups on the same day that the pupil-made-simulation treatment received its first post-test. The post-test mean scores for the three treatments were adjusted by an analysis of covariance in comparing group performance. Duncan's Multiple Range Test was used to determine the significance and order of differences between treatment group mean scores. The study revealed that students in the teacher-made and pupil-made-simulation treatments had significantly more favorable attitudes toward social studies than did the children in the control treatment. The teacher-made and pupi1-made- simulation treatments were found to be equally effective in influencing favorable student attitudes toward social studies. Conclusions and implications were drawn relevant to classroom practice and curriculum development.

description: Investigating the interaction of electrons in a superconductor by means of a method of solitary waves of Korteweg - de Vries, we refute the claim of absence of "Cooper pairs" in a superconductor. We also indicate that the nondissipative transfer of energy in the superconductor is possible only with the help of a pair of electrons.

description: Οι κοινωνικές ανισότητες αποτελούν μια πρόκληση και αυτό διότι προκύπτουν από ένα σύνολο παραγόντων και μπορούν να προσεγγιστούν για να επιλυθούν από ένα εύρη επιστημονικό φάσμα, όπως τα οικονομικά, η πολιτική, η κοινωνιολογία κ.α. Μια από τις σημαντικότερες κοινωνικές ανισότητες είναι αυτή του εισοδήματος. Έτσι και στην παρούσα ερευνητική προσπάθεια προσεγγίσουμε το ζήτημα της εισοδηματικής ανισότητας για τις χώρες-μελή της Ευρωπαϊκής Ένωσης από αυτή την σκοπιά, συγκριτικά με την Ελλάδα, μέσα από τις δυο πρόσφατες κρίσης (χρηματοπιστωτική, Covid-19). Σε αυτό το σημείο είναι σημαντικό να προσδιορίζουμε την σημαντικότητα της έρευνας μας, μιας και η εισοδηματική ανισότητα αφορά τον τρόπο με τον οποίο κατανέμεται το συνολικό διαθέσιμο εισόδημα μιας οικονομίας στο πληθυσμό της. Με του δυο σημαντικότερους δείκτες μέτρησης της να είναι ο δείκτης Gini και ο λόγος S80/S20. Στους οποίους θα κάνουμε χρήση στην ερευνητική μας προσπάθεια ώστε να μπορέσουμε να απαντήσουμε στα ερευνητικά μας ερωτήματα. Στα αποτελέσματα της ερευνά μας διακρίνεται η ύπαρξη σχέσης ανάμεσα στους δείκτες κοινωνικής ανισότητας Gini και S80/S20 με το Εθνικό Ακαθάριστο Προϊόν ανάμεσα στις χώρες μελή της Ευρωπαϊκής Ένωσης. Ακόμα αναφορικά με το βασικό ερώτημα μας για την επίδραση των κρίσεων στις εισοδηματικές ανισότητες ανάμεσα στην χώρα μας και τις χώρες μελή της ΕΕ. Τα αποτελέσματα που λάβαμε είναι ποιο ξεκάθαρα για το δείκτη S80/S20. Αυτό που προκύπτει είναι ότι η χρηματοπιστωτική κρίση του 2009 διόγκωσε τις εισοδηματικές ανισότητες για την χώρα μας συγκριτικά με τις χώρες ΕΕ ένα αντίθεση με την κρίση του Covid-19 που δεν διαπιστώθηκε κάποια αυξητική τάση στους δείκτες εισοδηματικής ανισότητας.

description: In this paper, the degenerate ground states of Z2 topological order on a plane with holes (the so-called surface codes) are used as the protected code subspace to build a topological quantum computer by tuning their quantum tunneling effect. Using a designer Hamiltonian - the Kitaev toric-code model as an example, we study quantum tunneling effects of the surface codes and obtain its effective theory. Finally, we show how to do topological quantum computation including the initialization, the unitary transformation and the measurement.

description: The initial reports of the presence of phosphine in the cloud decks of Venus has led to the suggestion that volcanism was the source of phosphine, through volcanic phosphides ejected into the clouds. Here we examine the idea that mantle plume volcanism, bringing material from the deep mantle to the surface, could generate observed amounts of phosphine through interaction of explosively erupted phosphide with sulfuric acid clouds. Direct eruption of deep mantle phosphide is unphysical, but shallower material could contain traces of phosphide, and could be erupted to the surface. Explosive eruption that efficiently transported material to the clouds would require ocean:magma interactions or subduction of hydrated oceanic crust, neither of which occur on modern Venus. The transport of erupted material to altitudes coinciding with the observations of phosphine is consequently very inefficient. Using the model proposed by Truong and Lunine as a base case, we estimate that an eruption volume of at least 21,600 km3/year would be required to explain the presence of 1 ppb phosphine in the clouds. This is greater than any historical terrestrial eruption rate, and would have several detectable consequences for remote and in situ observations to confirm. More realistic lithospheric mineralogy, volcano mechanics or atmospheric photochemistry require even more volcanism.
description: The paper expands on and confirms the results of Bains et al. 2021 arXiv:2009.06499 and provides further constrains on the model of the production of phosphine on Venus proposed by Truong and Lunine https://www.pnas.org/content/118/29/e2021689118 ; v2 is published in Universe

description: In this paper, we develop a quantum key distribution protocol based on the Greenberger-Horne-Zeilinger states (GHZs). The particles are exchanged among the users in blocks through two steps. In this protocol, for three-particle GHZs three keys can be simultaneously generated. The advantage of this is that the users can select the most suitable key for communication. The protocol can be generalized to $N$ users to provide $N$ keys. The protocol has two levels for checking the eavesdroppers. Moreover, we discuss the security of the protocol against different attacks.

description: Η Μικρασιατική καταστροφή εκτός από μελανό κομμάτι της ιστορίας αποτελεί και σημείο αναφοράς για την δημιουργία του ελληνικού κράτους, σε πρώιμη μορφή, όπως το ξέρουμε σήμερα όσον αφορά την έκταση, την ομοιογένεια και την εθνοποίηση. Αρχικά, πραγματοποιείται μια ενδεικτική αποτύπωση των γεγονότων και των προσώπων που διαδραμάτισαν πρωταρχικό ρόλο στη διαδρομή μέχρι την καταστροφή και τον ξεριζωμό των προσφύγων. Έπειτα, αναλύονται τα δεδομένα της εποχής με έμφαση στις άσχημες συνθήκες διαβίωσης των προσφύγων, προβάλλοντας την συμβολή της ΕΑΠ και τη δυσκολία του έργου της. Εν συνεχεία, περιγράφονται οι προσφυγικές ροές των οποίων η κινητικότητα ήταν έντονη κατά την πρώτη περίοδο του ξεριζωμού προς την Πελοπόννησο, με κατεύθυνση ιδιαίτερα την μεγαλύτερη πόλη της, την Πάτρα, κυρίως λόγο του λιμανιού. Παρ’ όλο που στην πρωτεύουσα του νομού συγκεντρώθηκε μεγάλος αριθμός προσφύγων το μεγαλύτερο ποσοστό αυτών παρατηρήθηκε στο Αίγιο. Η μικρή αυτή πόλη, αν και απροετοίμαστη, αγκάλιασε ένα τεράστιο, σε σχέση με τον πληθυσμό της, αριθμό προσφύγων. Τέλος, παρ’ όλο που χρειάστηκε να παρέλθει ένα σχετικά μεγάλο διάστημα για την στέγαση τους και την βελτίωση των συνθηκών διαβίωσης, η ενσωμάτωση τους ήταν αρκετά γρήγορη και σε μεγάλο βαθμό. Αυτό φαίνεται από την απορρόφηση τους στον εργασιακό τομέα αλλά και από την συμβολή τους στην ανάδειξη του πολιτισμού και του αθλητισμού της τοπικής κοινωνίας, όπως περιγράφονται στην εν λόγω εργασία.

description: The process of making blood smears is common in both research and clinical settings, for investigating the health of blood cells and the presence of blood-borne parasites. It is very often carried out manually. We focus here on smears for malaria diagnosis and research which are frequently analyzed by optical microscopy and require a high quality. Automating the smear preparation promises to increase throughput and to improve the quality and consistency of the smears. We present here two devices (manual and motorized) designed to aid in the making of blood smears. These are fully documented, open-source hardware, and an important principle was to make them easily fabricated locally anywhere. Designs and assembly instructions are freely available under an open license. We also describe an image analysis pipeline for characterizing the quality of smears, and use it to optimize the settings and tunable parameters in the two devices. The devices perform as well as expert human operators, while not requiring a trained operator and offering potential advantages in reproducibility and standardization across facilities.

description: We explore the low-temperature behavior of the Abelian Higgs model in AdS_4, away from the probe limit in which back-reaction of matter fields on the metric can be neglected. Over a significant range of charges for the complex scalar, we observe a second order phase transition at finite temperature. The symmetry-breaking states are superconducting black holes. At least when the charge of the scalar is not too small, we observe at low temperatures the emergence of a domain wall structure characterized by a definite index of refraction. We also compute the conductivity as a function of frequency.
