A formula for membrane mediated point particle interactions on near spherical biomembranes
Creators: name: Elliott, Charles M.
name: Herbert, Philip J.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We consider a model of a biomembrane with attached proteins. The membrane is represented by a near spherical continuous surface and attached proteins are described as discrete rigid structures which attach to the membrane at a finite number of points. The resulting surface minimises a quadratic elastic energy (obtained by a perturbation of the Canham-Helfrich energy) subject to the point constraints which are imposed by the attachment of the proteins. We calculate the derivative of the energy with respect to protein configurations. The proteins are constrained to move tangentially by translation and by rotation in the axis normal to a reference point. Previous studies have typically restricted themselves to a nearly flat membrane and circular inclusions. A numerically accessible representation of this derivative is derived and employed in some numerical experiments.
Research Infrastructures for Fair Data Sharing in the Heritage Sector
Creators: name: Richards, Julian

Publisher: name: Zenodo
Year: 2024

description: The European Commission is making major investments in research infrastructures and online data services in the heritage sector, with a plethora of national and European initiatives and a wealth of acronyms: Europeana, European Open Science Cloud (EOSC), E-RIHS (European Research Infrastructure for Heritage Science), and most recently the ECCCH (European Collaborative Cloud for Cultural Heritage), to name but a few. Many of these services are also being mirrored at national level. The landscape is crowded and confusing, but it is important that the archaeological and heritage sector makes the most of these new opportunities to leverage what we need. The ARIADNE Research Infrastructure has emerged from successive European investments as a Knowledge Base and data aggregator for our sector, now providing access to 4 million archaeological resources across 40 countries. Rather than a top-down initiative it is a community-driven membership association, developing and maintaining a sustainable aggregation service and research infrastructure for archaeological and heritage data. In 2024 it has embarked on a new 4-year EU-funded project, ATRIUM, to ensure it is embedded within broader Arts and Humanities research infrastructures (DARIAH, CLARIN and OPERAS) and the EOSC marketplace. It also a member of the ECHOES consortium, which is establishing the ECCCH, to be launched in September 2024. This paper will seek to introduce the rapidly changing landscape from the perspective of an infrastructure provider, seeking input from researchers and heritage professionals on their needs and how these new European-level investments can best serve the archaeological community.

Il legame emotivo con lo strumento musicale. Una ricerca con adolescenti allievi di scuole di musica.
Creators: name: Bozzato, Paolo
Publisher: name: De Musica
Year: 2019

description: È stato ancora poco studiato, nell'ambito della psicologia della musica, il rapporto che musicisti e studenti di musica hanno con il proprio strumento musicale. L'articolo presenta un contributo di ricerca che analizza, in una prospettiva psicologica, il legame emotivo instaurato da un campione di 58 adolescenti, allievi di scuole di musica classica, con lo strumento musicale. Si tratta di un gruppo composto da 37 femmine e 21 maschi, con un'età compresa tra gli 11 e i 17 anni, residenti in Lombardia, che suonano da almeno due anni alcuni dei principali strumenti dell'orchestra sinfonica moderna. Dall'analisi del contenuto, attraverso il software Atlas.ti, di componimenti scritti sul rapporto con il proprio strumento musicale è emersa una grande varietà di stati emotivi vissuti dagli adolescenti che testimoniano l'intensità emotiva di tale rapporto. Tali vissuti dipendono in parte dal brano suonato, in parte dall'autovalutazione della propria performance e ancora dall'azione stessa del suonare che genera, nella maggior parte dei casi, emozioni positive. Per la maggioranza degli intervistati lo strumento musicale non è un semplice oggetto, ma è percepito come un altro da sé significativo, con funzioni utili per la crescita e il benessere psicologico e relazionale. Personificato in un amico, compagno o confidente consente di sentirsi meno soli e di superare, grazie al suo aiuto, fatiche e difficoltà connesse alla crescita. La musica che nasce dal rapporto tra sé e questo alter ego consente di esprimere se stessi, le proprie emozioni, ma anche di evadere dalla realtà, di comunicare con gli altri quello che non si riesce a dire in altro modo e, infine, di sentirsi meglio in caso di difficoltà o problemi personali. Il legame emotivo istaurato con il proprio strumento musicale è risultato essere dunque intimo, coinvolgente e anche importante per la crescita e lo sviluppo del Sé.

Analogia e omologia nell’analisi interartistica: accostamenti ricettivi e processi creativi
Creators: name: Spampinato, Francesco
Publisher: name: De Musica
Year: 2019

description: Questo testo propone di utilizzare le due nozioni di analogia e omologia come chiave per la comprensione di alcune dimensioni della ricezione delle opere d’arte. Viene qui studiato, in particolare, il fenomeno degli accostamenti interartistici non giustificati dalla conoscenza del contesto storico-culturale di produzione. Si riconoscono qui i vari tipi di omologie possibili fra opere di ambiti artistici diversi e le varie fasi della morfogenesi espressiva che le ha originate, per poi presentare un modello omologico dell’immaginario interartistico che tenga conto tanto degli archetipi quanto dei processi di costituzione del senso.

description: Constraints on the Yukawa-type corrections to Newton's gravitational law and on the coupling constant of axionlike particles to nucleons obtained from different laboratory experiments are reviewed and compared. The constraints on non-Newtonian gravity under discussion cover the wide interaction range from nanometers to millimeters and follow from the experiments on neutron scattering, measuring the Casimir force and Cavendish-type experiments. The constraints on the axion-to-nucleon coupling constant following from the magnetometer measurements, Cavendish-type experiments, Casimir physics, and experiments with beams of molecular hydrogen are considered which refer to the region of axion masses from $10^{-10}$ eV to 200 eV. Particular attention is given to the recent constraints obtained from measuring the Casimir force at nanometer separation distance between the test bodies. Several proposed experiments focused on constraining the non-Newtonian gravity, axionlike particles and other hypothetical weakly interacting particles, such as chameleons and symmetrons, are discussed.

Leptogenesis implications in models with Abelian family symmetry and one extra real Higgs singlet

description: We show that the neutrino models, as suggested by Low, which have an additional Abelian family symmetry and a real Higgs singlet to the default see-saw do not hinder the possibility of successful thermal leptogenesis. For these models (neglecting radiative effects), we have investigated the situation of strong washout in both the one-flavor approximation and when flavor effects are included. The result is that while such models predict that theta_{13}=0 and that one light neutrino to be massless, they do not modify or provide significant constraints on the typical leptogenesis scenario where the final asymmetry is dominated by the decays of the lightest right-handed neutrinos.

Copper(I) chloride-mediated intramolecular conjugate additions of vinyltrimethylstannane functions to [alpha],[beta]-alkynic esters
Creators: name: Boehringer, Eva-Maria
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, the development of a method that effects copper(I) chloride-mediated intramolecular conjugate additions of vmyltrimethylstannane functions to a,|3-alkynic esters is described. The alJkenyltrimethylstannanes 21, 22 and 23 were prepared in a stereoselective fashion in moderate to good yields by the addition of hthium (trimethylstannyl)(cyano)cuprate (48) to the appropriate dialkyl dialkynedioates 42, 43 and 44. Syntheses of the alkenyltrimethylstannanes 31, 32, 33 and 37 were achieved by addition of methyl 3-lithiopropynoate (62) to the aldehydes 63, 66a, 66b and 70, respectively. These aldehydes were, in turn, prepared from the corresponding ß-trimethylstannyl a,ßy- or ßy-unsaturated esters (50, 68a, 68b, 72) via a sequence of standard transformations. The copper(I) chloride-mediated intramolecular conjugate additions of the alkenyltrimethylstannanes 21-23 and 31-33 were carried out successfully, thus demonstrating the viability of the proposed method. The general utility of the method was shown by the synthesis of several highly functionalized mono- and bicyclic ring systems (24-26, 34-36). A limitation of the method was shown by the failure of the attempted cyclization of the substituted alkenyltrimethylstannane 37. [Formula on pages 4 and 5 of Abstract]

description: We used existing data from the New Horizons LORRI camera to measure the optical-band ($0.4\lesssimλ\lesssim0.9{\rmμm}$) sky brightness within seven high galactic latitude fields. The average raw level measured while New Horizons was 42 to 45 AU from the Sun is $33.2\pm0.5{\rm ~nW ~m^{-2} ~sr^{-1}}.$ This is $\sim10\times$ darker than the darkest sky accessible to the {\it Hubble Space Telescope}, highlighting the utility of New Horizons for detecting the cosmic optical background (COB). Isolating the COB contribution to the raw total requires subtracting scattered light from bright stars and galaxies, faint stars below the photometric detection-limit within the fields, and diffuse Milky Way light scattered by infrared cirrus. We remove newly identified residual zodiacal light from the IRIS $100μ$m all sky maps to generate two different estimates for the diffuse galactic light (DGL). Using these yields a highly significant detection of the COB in the range ${\rm 15.9\pm 4.2\ (1.8~stat., 3.7~sys.) ~nW ~m^{-2} ~sr^{-1}}$ to ${\rm 18.7\pm 3.8\ (1.8~stat., 3.3 ~sys.)~ nW ~m^{-2} ~sr^{-1}}$ at the LORRI pivot wavelength of 0.608 $μ$m. Subtraction of the integrated light of galaxies (IGL) fainter than the photometric detection-limit from the total COB level leaves a diffuse flux component of unknown origin in the range ${\rm 8.8\pm4.9\ (1.8 ~stat., 4.5 ~sys.) ~nW ~m^{-2} ~sr^{-1}}$ to ${\rm 11.9\pm4.6\ (1.8 ~stat., 4.2 ~sys.) ~nW ~m^{-2} ~sr^{-1}}$. Explaining it with undetected galaxies requires the galaxy-count faint-end slope to steepen markedly at $V>24$ or that existing surveys are missing half the galaxies with $V< 30.$

description: Previous efforts in complex networks research focused mainly on the topological features of such networks, but now also encompass the dynamics. In this Letter we discuss the relationship between structure and dynamics, with an emphasis on identifying whether a topological hub, i.e. a node with high degree or strength, is also a dynamical hub, i.e. a node with high activity. We employ random walk dynamics and establish the necessary conditions for a network to be topologically and dynamically fully correlated, with topological hubs that are also highly active. Zipf's law is then shown to be a reflection of the match between structure and dynamics in a fully correlated network, as well as a consequence of the rich-get-richer evolution inherent in scale-free networks. We also examine a number of real networks for correlations between topology and dynamics and find that many of them are not fully correlated.

description: Electrical resistance tomography (ERT) -based distributed surface sensing systems, or sensing skins, offer alternative sensing techniques for structural health monitoring, providing capabilities for distributed sensing of, for example, damage, strain and temperature. Currently, however, the computational techniques utilized for sensing skins are limited to planar surfaces. In this paper, to overcome this limitation, we generalize the ERT-based surface sensing to non-planar surfaces covering arbitrarily shaped three-dimensional structures; We construct a framework in which we reformulate the image reconstruction problem of ERT using techniques of Riemannian geometry, and solve the resulting problem numerically. We test this framework in series of numerical and experimental studies. The results demonstrate that the feasibility of the proposed formulation and the applicability of ERT-based sensing skins for non-planar geometries.

Through practice-based design research, the methods and sites of inquiry bring design to embodied awareness and embodied awareness to design (Hayashi, 2021). The PhD develops open-ended awareness-based design prompts to support educators and learners to become aware of non-verbal, embodied and relational experiences within a social field (Böll & Senge, 2020; Scharmer & Kaeufer, 2015).

description: Το Δίκτυο εμπειρογνωμόνων της Βιοοικονομίας το 2018 όρισαν την BioWEconomy ως “την αειφόρα, κυκλική και μετασχηματιστική βιοοικονομία στην οποία οι κοινωνικές πτυχές έχουν μεγάλη σημασία”, καθώς συμβάλλουν στη διαμόρφωση μιας πιο ανθεκτικής και ανταγωνιστικής Ευρωπαϊκής Ένωσης. Όμως, δεν είναι κατ’ ανάγκη όλες οι βιοοικονομικές δραστηριότητες αειφόρες. Η ανατρεπτική κρίση της πανδημίας που προκλήθηκε από τον COVID-19 ενίσχυσε τη μεταμορφωτική σημασία της βιοοικονομίας στη μετατροπή των κοινωνικοοικονομικών προκλήσεων σε ευκαιρίες για την προώθηση της βιώσιμης ανάπτυξης. Η επιχειρηματικότητα, αν και είναι τόσο παλιά όσο και η οικονομική συμπεριφορά, έχει θεωρηθεί ως μια σχετικά νέα έννοια, ιδιαίτερα στον λόγο της βιοοικονομίας και στις αρχές της υπεύθυνης κατανάλωσης και παραγωγής. Επιπλέον, έχουν προκύψει από πρόσφατες μελέτες ότι μικρές εταιρείες και ειδικά spinoffs ή startups που έχουν προκύψει από ερευνητικά ιδρύματα ή/και πανεπιστήμια έχουν επιτύχει επαναστατικές ανακαλύψεις που αλλάζουν το επιχειρηματικό οικοσύστημα. Αυτή η διπλωματική εργασία λοιπόν εξετάζει τη βιώσιμη επιχειρηματικότητα ως μια προσέγγιση που γεφυρώνει το χάσμα μεταξύ της επιδίωξης κέρδους (κερδοσκοπίας) και της επίτευξης περιβαλλοντικών και κοινωνικών στόχων. Ερευνά πώς οι επιχειρήσεις που ακολουθούν τις αρχές της βιωσιμότητας κατορθώνουν να συνδυάσουν την επίτευξη περιβαλλοντικών και κοινωνικών στόχων με την οικονομική ευημερία, δημιουργώντας επιχειρηματικά μοντέλα που όχι μόνο αποφέρουν κέρδη, αλλά συμβάλλουν και στην επίλυση σημαντικών κοινωνικών και περιβαλλοντικών προβλημάτων. Η έρευνα θα αναλύσει διάφορες μορφές επιχειρηματικότητας, όπως την περιβαλλοντικά και κοινωνικά υπεύθυνη, καθώς και την επιχειρηματικότητα που στοχεύει στην αλλαγή θεσμών και κανόνων της αγοράς. Μέσω μελετών περίπτωσης και βιβλιογραφικής ανασκόπησης, η διπλωματική εργασία θα εξετάσει πώς ορισμένες επιχειρήσεις που έχουν υιοθετήσει τις αρχές της αειφόρα, κυκλικής και μετασχηματιστικής BioWEconomy κατάφεραν να κλιμακώσουν τις βιώσιμες καινοτομίες τους από μικρές και συγκεκριμένες αγορές σε ευρύτερες και πιο ακανόνιστες, οδηγώντας σε σημαντικές αλλαγές στο σύνολο της αγοράς, στην οικονομία και στην κοινωνία γενικότερα. Επιπλέον, αποσκοπεί στην παροχή καθοδήγησης σε υπεύθυνους χάραξης στρατηγικής και άλλους αρμόδιους, με στόχο την προώθηση μιας πιο βιώσιμης οικονομίας και ενός πιο υπεύθυνου ανταγωνισμού.

description: We develop a theory of the conductance of superconductor/normal metal/superconductor junctions in the case where the superconducting order parameter has d-wave symmetry. At low temperature the conductance is proportional to the square root of the inelastic electron relaxation time in the bulk of the superconductor. As a result it turns out to be much larger than the conductance of the normal part of the junction.

description: The research work presented in this paper proposes a data-driven modeling method for bearings remaining useful life estimation based on Takagi-Sugeno (T-S) fuzzy inference system (FIS). This method allows identifying the parameters of a classic T-S FIS, starting with a small quantity of data. In this work, we used the vibration signals data from a small number of bearings over an entire period of run-to-failure. The FIS model inputs are features extracted from the vibration signals data observed periodically on the training bearings. The number of rules and the input parameters of each rule of the FIS model are identified using the subtractive clustering method. Furthermore, we propose to use the maximum likelihood method of mixture distribution analysis to calculate the parameters of clusters on the time axis and the probability corresponding to rules on degradation stages. Based on this result, we identified the output parameters of each rule using a weighted least square estimation. We then benchmarked the proposed method with some existing methods from the literature, through numerical experiments conducted on available datasets to highlight its effectiveness.

description: The electric and magnetic black hole solutions are found by coupling the recently introduced nonlinear electrodynamics (NED) model, called "double logharitmic nonlinear electrodynamics" with cosmological Einstein gravity. The solutions become Reissner-Nordstrom (RN) black hole in the weak field limit and asymptotically. The electric solution is expressed as an integral equation while the magnetic black hole solution is expressed in terms of elementary functions. Hence, the thermodynamic structure of the magnetic black hole solution is analyzed by deriving the modified Smarr's formula and studying the first law of thermodynamics. Moreover, its stability is investigated by deriving the heat capacity.

description: This paper is devoted to a fractional generalization of the Dirichlet distribution. The form of the multivariate distribution is derived assuming that the $n$ partitions of the interval $[0,W_n]$ are independent and identically distributed random variables following the generalized Mittag-Leffler distribution. The expected value and variance of the one-dimensional marginal are derived as well as the form of its probability density function. A related generalized Dirichlet distribution is studied that provides a reasonable approximation for some values of the parameters. The relation between this distribution and other generalizations of the Dirichlet distribution is discussed. Monte Carlo simulations of the one-dimensional marginals for both distributions are presented.

description: Rotational superradiance affects the dynamics of many rotating systems in nature, through either stimulated or spontaneous extraction of energy and angular momentum. By now, this process is well-studied in the relativistic setting, where systems are intrinsically dispersion-free. In many condensed matter systems, however, dispersion is an unavoidable aspect of the description for the short wavelength modes. For these systems, how might one expect superradiance to be modified? In this work, an answer to this question is provided using an illustrative example. The scattering of linear excitations of a Bose-Einstein condensate are studied in the presence of a rotating, draining vortex flow using the full Bogoliubov dispersion relation. It is shown that dispersion suppresses the extraction of energy and angular momentum, firstly, by decreasing the superradiant bandwidth, and secondly, by preventing high-angular momentum modes from superradiating.

Thermodynamics with generalized ensembles: The class of dual orthodes

Publisher: name: arXiv
Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We address the problem of the foundation of generalized ensembles in statistical physics. The approach is based on Boltzmann's concept of orthodes. These are the statistical ensembles that satisfy the heat theorem, according to which the heat exchanged divided by the temperature is an exact differential. This approach can be seen as a mechanical approach alternative to the well established information-theoretic one based on the maximization of generalized information entropy. Our starting point are the Tsallis ensembles which have been previously proved to be orthodes, and have been proved to interpolate between canonical and microcanonical ensembles. Here we shall see that the Tsallis ensembles belong to a wider class of orthodes that include the most diverse types of ensembles. All such ensembles admit both a microcanonical-like parametrization (via the energy), and a canonical-like one (via the parameter $β$). For this reason we name them ``dual''. One central result used to build the theory is a generalized equipartition theorem. The theory is illustrated with a few examples and the equivalence of all the dual orthodes is discussed.

description: In the layered transition metal oxide LiNbO$_2$ the Nb$^{3+}$ ($4d^2$) ion is trigonal-prismatically coordinated with O ions, with the resulting crystal field leading to a single band system for low energy properties. A tight-binding representation shows that intraplanar second neighbor hopping $t_2 = 100$ meV dominates the first neighbor interaction ($t_1 = 64$ meV). The first and third neighbor couplings are strongly modified by oxygen displacements of the symmetric Raman-active vibrational mode, and electron-phonon coupling to this motion may provide the coupling mechanism for superconductivity in Li-deficient samples (where $T_c = 5$ K). We calculate all zone-center phonon modes, identify infrared (IR) and Raman active modes, and report LO-TO splitting of the IR modes. The Born effective charges for the metal ions are found to have considerable anisotropy reflecting the degree to which the ions participate in interlayer coupling and covalent bonding. Insight into the microscopic origin of the valence band density, composed of Nb $d_{z^2}$ states with some mixing of O $2p$ states, is obtained from examining Wannier functions for these bands.

description: We use a combination of computer simulations and iso-flux tension propagation (IFTP) theory to investigate translocation dynamics of a flexible linear polymer through a nanopore into an environment composed of repulsive active rods in 2D. We demonstrate that the rod activity induces a crowding effect on the polymer, leading to a time-dependent net force that facilitates translocation into the active environment. Incorporating this force into the IFTP theory for pore-driven translocation allows us to characterise translocation dynamics in detail and derive a scaling form for the average translocation time as $\tildeτ \sim \tilde{L}_{\textrm{r}}^ν / \tilde{F}_{\textrm{SP}} $, where $\tilde{L}_{\textrm{r}}$ and $\tilde{F}_{\textrm{SP}}$ are the rod length and self-propelling force acting on the rods, respectively, and $ν$ is the Flory exponent.
Aesthetic learning : an exploration of a radical aesthetic in feminist documentary film
Creators: name: Rogers, Pamela A.
Publisher: name: University of British Columbia
Year: 2009

description: This study emerged from a curiosity about the powerful affect of feminist documentary film and an interest in transformative learning approaches. Three films of Studio D—the former feminist production unit of the National Film Board of Canada [NFB] were explored: Goddess Remembered (1989), Burning Times (1990), and Full Circle (1992). For methodology, I used an adaptation of autobiography, film and literary criticism and I explored the aesthetics of these films. Beginning with an in-depth look at the characteristics and criticisms of feminist documentary film, I identified the feminist perspective as having a transformative influence on traditional documentary styles. In my analysis, I defined and articulated the aesthetic quality of the films. This quality is defined as a radical aesthetic. The definition also includes a suggestion that an asethetic experience is spatial. I argue that the radical aesthetic, in its spatiality and feminist analysis, is able to evoke yearning, creative inspiration and a sense of place in viewers, particularly women. The analysis identifies the characteristics of the radical aesthetic and the significance of this on transformative learning experiences for women. The study claims that this radical aesthetic enhances two crucial stages in transformative learning. One, since an aesthetic experience is spatial, a space in which a learner can think, imagine and act is created. Two, in its provocative quality, a radical aesthetic assists women to become aware of and connected to a subterranean layer of self-knowledge that is seldom acknowledged in typical transformative learning approaches. I discuss the importance of this layer of knowledge in stimulating and sustaining transformative learning. Implications for practice include a discussion on the need to understand the role and the power of aesthetics in learning. Here a set of questions was created that can be used to explore the aesthetic experience of other films. Recommendations were made for further study on the relationship of aesthetic learning and feminist pedagogy. Given the spatial experience of aesthetics and the importance of space for women, other research was suggested to look at the role of place in learning.
Reconceptualising world order : transnational identities and English school theory
Creators: name: Haddon, Joseph
Publisher: name: University Of Tasmania
Year: 2024

description: Theorists of world order have often contrasted the international society of states to a global society of individuals. While the former is positioned as the ‘real’ structure of world order, the latter has often been cast as an unrealistic and unrealisable form of human social organisation. At the same time, however, ideas of human community beyond the nation-state have clearly helped inform modern international relations. How can we reconcile these visions of world society with a global order created by and for states? This thesis adds to English School theory through a reconsideration of the relationship between the concepts of international and world society. Through a synthesis of existing English School contributions and relational constructivist approaches, it recovers the importance of transnational communities to individual nation-states and the international society they have formed. Importantly, the framework developed here supplements, rather than replaces, existing English School contributions, allowing deeper analysis of the sociological processes through which the concepts of world and international society constitute each other. The utility of these frameworks is then demonstrated through a short analysis of the global ideational forces informing Australia’s engagement with international institutions.

description: The Norwegian university museums cooperate in National data infrastructures for archaeology. The new web-based user interface for the Archaeology system was launched in January 2024, following the completion of the new system for Numismatics in 2021 and Ethnography in 2022. This work included migration of data from the Delphi-based MUSIT database to the new UniMus database, which is a Postgres system using an event-based datamodel. Data from all museums is published at the Unimusportal (unimus.no/portal) and is also downloadable from unimus.no. This georeferenced archaeological data from UnimusArk is also made available through the Ariadne portal (https://portal. ariadne-infrastructure.eu/).

Another part of the National infrastructure is ADED (Archaeological Digital Excavation Documentation). ADED mainly contains detailed GIS excavation information from 2011 onwards and includes links to excavation photos and artefact records held in the other shared databases. Earlier excavations will be included later.

The Museum of Cultural History (MCH), in close cooperation with DARK Lab (darklab.lu.se) at Lund University and the Visual Computing Lab (ISTI –CNR) has developed the BItFROST platform, based on 3DHOP, for the museum’s 3D models. It is currently used for 3D models of artefacts, but extended applications will also include excavation data. The possibilities for sharing annotations and commented models are important features of BItFROST and there is potential for this system to be developed into another element of the national infrastructure.

MCH has come a long way in making its archaeological data FAIR. The aspect of reusability is especially receiving special attention this year through the project UI3D (Understanding and Immersion in 3D). UI3D aims to address reuse and active use of Heritage Data in Teaching and Research. It is funded by the University of Oslo’s framework for competence hubs in IT research and will interact with the ERASMUS+ cooperation Virtual Worlds Teaching in Archaeology.

Energy conditions bounds and their confrontation with supernovae data

description: The energy conditions play an important role in the understanding of several properties of the Universe, including the current accelerating expansion phase and the possible existence of the so-called phantom fields. We show that the integrated bounds provided by the energy conditions on cosmological observables such as the distance modulus $μ(z)$ and the lookback time $t_L(z)$ are not sufficient (nor necessary) to ensure the local fulfillment of the energy conditions, making explicit the limitation of these bounds in the confrontation with observational data. We recast the energy conditions as bounds on the deceleration and normalized Hubble parameters, obtaining new bounds which are necessary and sufficient for the local fulfillment of the energy conditions. A statistical confrontation, with $1σ-3σ$ confidence levels, between our bounds and supernovae data from the gold and combined samples is made for the recent past. Our analyses indicate, with $3σ$ confidence levels, the fulfillment of both the weak energy condition (WEC) and dominant energy condition (DEC) for $z \leq 1$ and $z \lesssim 0.8$, respectively. In addition, they suggest a possible recent violation of the null energy condition (NEC) with $3σ$, i.e. a very recent phase of super-acceleration. Our analyses also show the possibility of violation of the strong energy condition (\textbf{SEC}) with $3σ$ in the recent past ($z \leq 1$), but interestingly the $q(z)$-best-fit curve crosses the SEC-fulfillment divider at $z \simeq 0.67$, which is a value very close to the beginning of the epoch of cosmic acceleration predicted by the standard concordance flat $Λ$CDM scenario.

A reduced subduction graph and higher multiplicity in S_n transformation coefficients

description: Transformation coefficients between {\it standard} bases for irreducible representations of the symmetric group $S_n$ and {\it split} bases adapted to the $S_{n_1} \times S_{n_2} \subset S_n$ subgroup ($n_1 +n_2 = n$) are considered. We first provide a \emph{selection rule} and an \emph{identity rule} for the subduction coefficients which allow to decrease the number of unknowns and equations arising from the linear method by Pan and Chen. Then, using the {\it reduced subduction graph} approach, we may look at higher multiplicity instances. As a significant example, an orthonormalized solution for the first multiplicity-three case, which occurs in the decomposition of the irreducible representation $[4,3,2,1]$ of $S_{10}$ into $[3,2,1] \otimes [3,1]$ of $S_6 \times S_4$, is presented and discussed.

description: Σκοπός της εργασίας ήταν η μελέτη της παρουσίας οκτώ καρβοξυλικών οξέων (οξικό, προπανοϊκό, βουτανοϊκό, πεντανοϊκό, εξανοϊκό, οκτανοϊκό, εννεανοϊκό και δεκανοϊκό οξύ) και ο σχηματισμός τους κατά τον οζονισμό του πόσιμου νερού. Αναφέρθηκε ο ρόλος του οζονισμού στην κατεργασία του πόσιμου νερού και αναλύθηκαν οι μηχανισμοί, μέσω των οποίων μπορούν να σχηματιστούν καρβοξυλικά οξέα κατά την οξείδωση της φυσικής οργανικής ύλης των νερών. Ακόμη, δόθηκαν κάποιες πληροφορίες τοξικότητας των οξέων και αναφέρθηκαν οι μέχρι τώρα αναλυτικές τεχνικές προσδιορισμού τους. Επιπλέον, περιγράφηκε η μέθοδος SPE/GC-MS που αναπτύχθηκε και εφαρμόστηκε σε δείγματα από επτά διαφορετικά στάδια της Εγκατάσταση Επεξεργασίας Νερού Θεσσαλονίκης. Τα επίπεδα των οξέων κυμάνθηκαν σε τιμές ως επί το πλείστον μικρότερες των ορίων ανίχνευσης και συσχετίστηκαν με διάφορες παραμέτρους (άθροισμα οξέων, DOC, SUVA, δόση όζοντος, pH, θερμοκρασία, υδρόφιλο, υδρόφοβο και αμφίφιλο κλάσμα της ΝΟΜ). Σε γενικές γραμμές, παρατηρήθηκε σημαντική αύξηση των συγκεντρώσεων στα στάδια οζονισμού, μέτρια απομάκρυνση στα στάδια κροκίδωσης και κλινών άμμου και ικανοποιητική απομάκρυνση στις κλίνες άνθρακα.
description: The aim of the present thesis was to study the presence of eight carboxylic acids (acetic, propanoic, butanoic, pentanoic, hexanoic, octanoic, nonanoic and decanoic acid) and their formation during the ozonation of drinking water. The role of the ozonation in the drinking water treatment process is described, along with the mechanisms through which carboxylic acids may be formed due to the oxidation of natural organic matter in the waters. Furthemore, toxicity information of the acids is given, and the analytical techniques that are currently used for their determination are mentioned. The SPE/GC-MS method that was developed in the present study was described. The method was applied to water samples collected from seven different stages of a water treatment facility . The acid levels were found for the greater part to be below the detection limits and were correlated with various parameters (sum of the acids, DOC, SUVA, ozon dosage, pH, temperature, hydrophilic, hydrophobic and transphilic fraction of ΝΟΜ). Generally, a significant increase in the acids’ concentrations was observed at the ozonation stages. Finally, at the carbon bed filters of the facility the removal of the acids was more satisfactory than at the flocculation and sand filter stages.
