description: We systematically investigate the structural, electronic and magnetic properties of Mn$_n$ clusters ($n =$ 2$-$20) within the {\it ab-initio} pseudopotential plane wave method using generalized gradient approximation for the exchange-correlation energy. A new kind of icosahedral structural growth has been predicted in the intermediate size range. Calculated magnetic moments show an excellent agreement with the Stern-Gerlach experiment. A transition from ferromagnetic to ferrimagnetic Mn$-$Mn coupling takes place at $n=$ 5 and the ferrimagnetic states continue to be the ground states for the entire size range. Possible presence of multiple isomers in the experimental beam has been argued. No signature of non-metal to metal transition is observed in this size range and the coordination dependence of $d-$electron localization is discussed.

description: Disks of gas accreting onto supermassive black holes are thought to power active galactic nuclei (AGN). Stars may form in gravitationally unstable regions of these disks, or may be captured from nuclear star clusters. Because of the dense gas environment, the evolution of such embedded stars can diverge dramatically from those in the interstellar medium. This work extends previous studies of stellar evolution in AGN disks by exploring a variety of ways that accretion onto stars in AGN disks may differ from Bondi accretion. We find that tidal effects from the supermassive black hole significantly alter the evolution of stars in AGN disks, and that our results do not depend critically on assumptions about radiative feedback on the accretion stream. Thus, in addition to depending on $ρ/c_s^3$, the fate of stars in AGN disks depends sensitively on the distance to and mass of the supermassive black hole. This affects where in the disk stellar explosions occur, where compact remnants form and potentially merge to produce gravitational waves, and where different types of chemical enrichment take place.

description: Τhe issue of the present thesis is the conscientious objection to military service. Initially, we examined the freedom of conscience and its relationship with conscientious objection by referring to provisions of the Greek Constitution, the European Convention on Human Rights, the Charter of Fundamental Rights of the European Union and the most important International Treaties. Additionally, we studied and introduced thoroughly the development of greek legislation of conscription in regard to the crucial ordinances of the Greek Constitutions and the handling of conscientious objectors affair through the time passing. Subsequently, we described concisely and comparatively to the Greek Law the constitutional and legislative rules of several European States concerning the religious freedom, the freedom of conscience and conscientious objection. Furthermore, we pointed to a few extracts of jurisprudence of the Supreme Administrative Court, the European Commission of Human Rights and the European Court of Human Rights.

description: We performed a measurement of differential and integral jet shapes in proton-carbon, proton-tungsten and proton-aluminium collisions at 920 GeV/c proton momentum with the HERA-B detector at HERA for the jet transverse energies in the range 4 < E_T(jet) < 12 GeV. Jets were identified using the k_T-clustering algorithm. The measurements were performed for the hardest jet in the event, directed towards the opposite side with respect to the trigger direction. Jets become narrower with increasing transverse energy and measured distributions agree well with predictions of the PYTHIA 6.2 model. We do not observe any significant difference in the jet shape for the carbon and the aluminium targets. Nevertheless, the transverse energy flow at small and large radii for the tungsten sample is slightly less than for light nuclei. This observation indicates some influence of the nuclear environment on the formation of jets in heavy nuclei, especially at lower transverse energies, 5 < E_T(jet) < 6 GeV.

description: Many people have never heard of homocycteine, yet elevated levels of this naturally occurring amino acid can actually increase risk of some serious helth conditions. Homocysteine is an amino acid. Amino acids are chemicals in your blood that help create proteins. Vitamin B12, vitamin B6 and vitamin B9 (folate) break down homocysteine to generate other chemicals your body needs. Many people have never heard of homocycteine, yet elevated levels of this naturally occurring amino acid can actually increase risk of some serious helth conditions.
Constructing a Distance Sensitivity Oracle in $O(n^{2.5794}M)$ Time

description: We continue the study of distance sensitivity oracles (DSOs). Given a directed graph $G$ with $n$ vertices and edge weights in $\{1, 2, \dots, M\}$, we want to build a data structure such that given any source vertex $u$, any target vertex $v$, and any failure $f$ (which is either a vertex or an edge), it outputs the length of the shortest path from $u$ to $v$ not going through $f$. Our main result is a DSO with preprocessing time $O(n^{2.5794}M)$ and constant query time. Previously, the best preprocessing time of DSOs for directed graphs is $O(n^{2.7233}M)$, and even in the easier case of undirected graphs, the best preprocessing time is $O(n^{2.6865}M)$ [Ren, ESA 2020]. One drawback of our DSOs, though, is that it only supports distance queries but not path queries. Our main technical ingredient is an algorithm that computes the inverse of a degree-$d$ polynomial matrix (i.e. a matrix whose entries are degree-$d$ univariate polynomials) modulo $x^r$. The algorithm is adapted from [Zhou, Labahn, and Storjohann, Journal of Complexity, 2015], and we replace some of its intermediate steps with faster rectangular matrix multiplication algorithms. We also show how to compute unique shortest paths in a directed graph with edge weights in $\{1, 2, \dots, M\}$, in $O(n^{2.5286}M)$ time. This algorithm is crucial in the preprocessing algorithm of our DSO. Our solution improves the $O(n^{2.6865}M)$ time bound in [Ren, ESA 2020], and matches the current best time bound for computing all-pairs shortest paths.

description: This deliverable provides an initial version of the RELIANCE data management plan (DMP), following the template provided by the European Commission in the Participant Portal. The document outlines data that will be collected or generated during the project and discusses how it will be handled during and after the project lifetime. As part of the Open Research Data Pilot (ORDP), RELIANCE delivers a first version of the DMP at an early stage of the project. This first version focusses on already identified research data to be collected, used and/or produced by the project, particularly by our scientific communities as part of the implementation of their use cases, but also the user data collected by the RELIANCE services. Additional data or updated data to be used/produced by the use cases will be detailed in the public deliverable of the use cases D7.1 in M12, and accordingly the DMP will be updated. Similarly, the DMP will be updated over the course of the project whenever significant changes arise, e.g., new data is used/produced. A final version of the DMP will be delivered at M24, which will include more detailed plan regarding external data sharing, use and exploitation after the end of the project. In addition to the official releases in the form of deliverables, the DMP is planned to be maintained in Argos, the EOSC service enabling the management of DMPs.

description: By using nanosecond laser pulses at 532-nm wavelength, we have intensively studied the optical limiting and nonlinear optical properties of some new composites which consist of mono-functional 1,2-dihydro-1,2-methanofullerene[60]-61-carboxylic acid (FCA), multifunctional fullerenol, and supramolecular C60(HNC4H8NCH3)9 - containing polymers. The optical limiting performance of FCA/poly(styrene-co-4-vinylpyridine) is found to be better than that of its parent C60, while the multi-functional Fullerenol and supramolecular C60(HNC4H8NCH3)9 incorporated with polymers show poorer optical limiting responses. The possible sources for the improvement in the optical limiting are discussed.

Explaining the MiniBooNE Anomalous Excess via Leptophilic ALP-Sterile Neutrino Coupling

description: Recently, the MiniBooNE experiment at Fermilab has updated the results with increased data and reported an excess of $560.6 \pm 119.6$ electronlike events ($4.7σ$) in the neutrino operation mode. In this paper, we propose a scenario to account for the excess where a Dirac-type sterile neutrino, produced by a charged kaon decay through the neutrino mixing, decays into a leptophilic axionlike particle ($\ell$ALP) and a muon neutrino. The electron-positron pairs produced from the $\ell$ALP decays can be interpreted as electronlike events provided that their opening angle is sufficiently small. In our framework, we consider the $\ell$ALP with a mass $m^{}_a = 20\,\text{MeV}$ and an inverse decay constant $c^{}_e/f^{}_a = 10^{-2}\,\text{GeV}^{-1}$, allowed by the astrophysical and experimental constraints. Then, after integrating the predicted angular or visible energy spectra of the $\ell$ALP to obtain the total excess event number, we find that our scenario with sterile neutrino masses within $150\,\text{MeV}\lesssim m^{}_N \lesssim 380 \,\text{MeV}$ ($150\,\text{MeV}\lesssim m^{}_N \lesssim 180 \,\text{MeV}$) and neutrino mixing parameters between $10^{-10} \lesssim |U_{μ4}|^2 \lesssim 10^{-8}$ ($3\times 10^{-7} \lesssim |U_{μ4}|^2 \lesssim 8 \times10^{-7}$) can explain the MiniBooNE data.

description: Purpose: In spite of improvements in language outcomes for children with hearing loss (HL) arising from cochlear implants (CIs), these children can falter when it comes to academic achievement, especially in higher grades. Given that writing becomes increasingly relevant to educational pursuits as children progress through school, this study explored the hypothesis that one challenge facing students with CIs may be written language.Method: Participants were 98 eighth graders: 52 with normal hearing (NH) and 46 with severe-to-profound HL who used CIs. Oral and written narratives were elicited and analyzed for morphosyntactic complexity and global narrative features. Five additional measures were collected and analyzed as possible predictors of morphosyntactic complexity: Sentence Comprehension of Syntax, Grammaticality Judgment, Expressive Vocabulary, Forward Digit Span, and Phonological Awareness.Results: For oral narratives, groups performed similarly on both morphosyntactic complexity and global narrative features; for written narratives, critical differences were observed. Compared with adolescents with NH, adolescents with CIs used fewer markers of morphosyntactic complexity and scored lower on several global narrative features in their written narratives. Adolescents with NH outperformed those with CIs on all potential predictor measures, except for Sentence Comprehension of Syntax. Moderately strong relationships were found between predictor variables and individual measures of morphosyntactic complexity, but no comprehensive pattern explained the results. Measures of morphosyntactic complexity and global narrative features were not well correlated, suggesting these measures are assessing separate underlying constructs.Conclusions: Adolescents with CIs fail to show writing proficiency at high school entry equivalent to that of their peers with NH, which could constrain their academic achievement. Interventions for children with CIs need to target writing skills, and writing assessments should be incorporated into diagnostic assessments.

Attribute Value Reordering For Efficient Hybrid OLAP

Year: 2007
Subjects: subject: Databases (cs.DB)
subject: FOS: Computer and information sciences

description: The normalization of a data cube is the ordering of the attribute values. For large multidimensional arrays where dense and sparse chunks are stored differently, proper normalization can lead to improved storage efficiency. We show that it is NP-hard to compute an optimal normalization even for 1x3 chunks, although we find an exact algorithm for 1x2 chunks. When dimensions are nearly statistically independent, we show that dimension-wise attribute frequency sorting is an optimal normalization and takes time O(d n log(n)) for data cubes of size n^d. When dimensions are not independent, we propose and evaluate several heuristics. The hybrid OLAP (HOLAP) storage mechanism is already 19%-30% more efficient than ROLAP, but normalization can improve it further by 9%-13% for a total gain of 29%-44% over ROLAP.

description: We study the effect of a constant electrical field applied on vicinal surfaces such as the Si$(111)$ surface. An electrical field parallel to the steps induces a meandering instability with a nonzero phase shift. Using the Burton-Cabrera-Frank model, we extend the linear stability analysis performed by Liu, Weeks and Kandel (Phys. Rev. Lett. {\bf 81}, p.2743, 1998) to the nonlinear regime for which the meandering amplitude is large. We derive an amplitude equation for the step dynamics using a highly nonlinear expansion method. We investigate numerically two limiting regimes (small and large attachment lengths) which both reveal long-time coarsening dynamics.

description: Virtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the dimensions of the virtual environment match those of the real world. The problem of most navigation techniques is that they produce motion sickness because the optical flow observed does not match the vestibular and proprioceptive information that appears during real physical movement. Walk in place is a technique that can successfully reduce motion sickness without losing presence in the virtual environment. It is suitable for navigating in a very large virtual environment but it is not usually needed in small virtual spaces. Most current work focuses on one specific navigation metaphor, however in our experience we have observed that if users are given the possibility to use walk in place for large distances, they tend to switch to normal walk when they are in a confined virtual area (such as a small room). Therefore, in this paper we present our ongoing work to seamlessly switch between two navigation metaphors based on leg and head tracking to achieve a more intuitive and natural virtual navigation.

Τα ερευνητικά ερωτήματα που θέτονται προς διερεύνηση αφορούν στην εξέταση του τρόπου με τον οποίο η φυλή, στην προκειμένη περίπτωση το να ανήκεις στην κοινότητα των Ρομά, υπεισέρχεται στον τρόπο κατανόησης και βίωσης της ψυχικής διαταραχής, καθώς και στο να εντοπιστούν τα θέματα που προκύπτουν, όταν οι Ρομά διαπραγματεύονται ζητήματα ψυχικής υγείας. Μέθοδος: Το δείγμα αποτελείται από 8 συμμετέχοντες, 3 άνδρες και 5 γυναίκες Ρομά που κάνουν χρήση των υπηρεσιών του Κέντρου Παιδικής Φροντίδας της περιοχής του Δροσερού του Δήμου Ξάνθης και αναφέρουν ότι πάσχουν από προβλήματα ψυχικής υγείας. Τα δεδομένα προσεγγίστηκαν ποιοτικά και η συλλογή τους έγινε με τη χρήση ημι-δομημένων, ανοιχτού τύπου συνεντεύξεων, ενώ η ανάλυση των αποτελεσμάτων έγινε με τη μέθοδο της ερμηνευτικής φαινομενολογικής ανάλυσης (Interpretative Phenomenological Analysis, IPA). Αποτελέσματα: Από την αναλυτική διαδικασία προέκυψαν κεντρικές θεματικές ενότητες, στο σύνολο τους πέντε, οι οποίες αποτελούνται από επιμέρους θέματα. Τα αποτελέσματα κατέδειξαν ότι κυρίαρχη αναπαράσταση στις εμπειρίες των τσιγγάνων είναι το ιατρικό μοντέλο κατανόησης και επεξήγησης της ψυχικής διαταραχής. Επίσης, φάνηκε ότι η τσιγγάνικη κουλτούρα και η τσιγγάνικη ταυτότητα αποτελούν σημαντικούς παράγοντες διαμόρφωσης τόσο των αναπαραστάσεων για την ψυχική διαταραχή όσο και των επιπτώσεων που βιώνονται.
description: The aim of the present study is to investigate how the Roma identity influences the way the Roma people deal with their mental health issues. The research inquiry is to understand the way the Roma ethnicity influences the experience and understanding of a mental disorder and the emerging issues of dealing with them. Method: The sample comprises of eight participants, three Roma men and five Roma women, which use the Child Care Centre service in the Drosero area of Xanthi Municipality and they report psychological problems. The data was analyzed qualitatively and was gathered using the semi-structured interview, with open-ended questions. The results were analyzed using the Interpretative Phenomenological Analysis (IPA) method. Results: Five master themes resulted with further subtopics. The study showed that the Roma experience of mental disorder is mainly represented by the biomedical model of understanding and explanation. It was also shown that the Roma culture and identity are primary factor of shaping the representation of mental disorder and the experiencing consequences.

description: Spin-disorder resistivity of Fe and Ni is studied using the noncollinear density functional theory. The Landauer conductance is averaged over random disorder configurations and fitted to Ohm's law. The distribution function is approximated by the mean-field theory. The dependence of spin-disorder resistivity on magnetization in Fe is found to be in excellent agreement with the results for the isotropic s-d model. In the fully disordered state, spin-disorder resistivity for Fe is close to experiment, while for fcc Ni it exceeds the experimental value by a factor of 2.3. This result indicates strong magnetic short-range order in Ni at the Curie temperature.

description: We study QCD effects in single graviton production at the CERN Large Hadron Collider (LHC) in the Randall-Sundrum (RS) Model. We present in detail the complete next-to-leading order (NLO) QCD corrections to the inclusive total cross sections. The NLO QCD corrections enhance significantly the total cross sections and decrease efficiently the dependence of the total cross sections on the factorization and renormalization scales. We also examine the uncertainty of the total cross sections due to the parton distribution function (PDF) uncertainties. For the differential cross sections on the transverse momentum ($q_T$) of the graviton, within the CSS resummation formalism, we resum the logarithmically-enhanced terms at small $q_T$ to all orders up to NLO logatithmic accuracy. Combined with the fixed order calculations, we give consistent predictions for both small $q_T$ and large $q_T$.

Women’s experience of recurrent early pregnancy loss

Publisher: name: University of British Columbia

description: There is a paucity of research which explores women's experience with recurrent early pregnancy loss. This grounded theory study explored, described, and explained the basic social psychological process of recurrent early pregnancy loss. This grounded theory study included 12 women who had experienced at least two consecutive early pregnancy losses. The data were collected by 18 unstructured tape-recorded interviews. Interviews were analysed using constant comparative analysis. The core category of the spiraling cycle of hope and loss emphasized the major behavioural and interactional variation within the process of recurrent early pregnancy loss. Six selective categories and their properties were related to the core category: cautious celebrating; losing the pregnancy; mourning the loss; searching and seeking; deciding what next; and hope. The findings indicated that the experience of recurrent early pregnancy loss is substantive in nature, and the women experienced a unique grieving process. Based on the findings of this study, the implications for nursing practice, education and research were identified in order to enable health care providers to formulate an effective therapeutic course of recovery and care for these women.

description: If we consider the gravitational collapse of a material object to a black hole, we would expect, for ranges of mass where a black hole would form, the following scenario. A large enough object would collapse classically until an event horizon forms, and to an external observer the object would be lost fom view. However, once the horizon has formed the black hole will begin to emit Hawking radiation and the hole will lose mass and the horizon will shrink. The final state of this process could be either a zero-mass "black hole" with consequent information loss, or some sort of "quantum remnant. A complete investigation of this process would require: 1) A complete and consistent theory of quantum gravity coupled to some kind of field that would provide the Hawking radiation (which could be the gravitational field itself --gravitons); 2) Some kind of definition of a "horizon" in this quantum gravity, and; 3) The calculational tools to achieve a description of the scenario. Lacking these, one may resort to toy models to try to give some sort of preliminary answer. In this paper we will consider the collapse of an infinitesimally thin dust shell in 2+1 gravity, where an exact minisuperspace quantum solution exists, and try to make rough estimates of the collapse-Hawking radiation-remnant formation process.

description: A new N-methoxy-1-pyridone alkaloid [chromenopyridin A (1)] and four known compounds (2–5) were isolated and identified from the endophytic fungus Penicillium nothofagi P-6, which was derived from the bark of the critically endangered conifer Abies beshanzuensis. Their structures were elucidated by extensive spectroscopic analyses and single-crystal X-ray diffraction. Among the isolates, compound 1 showed considerable cytotoxicities against the A549 and Hela human cancer cell lines, with IC50 values of 14.7 and 11.3 μM. In addition, compounds 1 and 4 exhibited potent antibacterial activity against Staphylococcus aureus with MIC values of 62.5 and 15.6 μg/mL, respectively.

description: We characterize Hilbert spaces in the class of all Banach spaces using Fourier transform of vector-valued functions over the field $Q_p$ of $p$-adic numbers. Precisely, Banach space $X$ is isomorphic to a Hilbert one if and only if Fourier transform $F: L_2(Q_p,X)\to L_2(Q_p,X)$ in space of functions, which are square-integrable in Bochner sense and take value in $X$, is a bounded operator.

description: We obtain asymptotic expressions for the Green kernels of certain non-translation invariant transition matrices using methods of semiclassical and microlocal analysis. Combined with a result by Bach and Møller this yields asymptotic formulas for the truncated two-point correlation functions of certain non-translation invariant lattice models of real-valued spins.

description: Σκοπός της διατριβή αυτής ήταν η μελέτη της δυναμικής των σολιτονίων σε συζευγμένα μη γραμμικά συστήματα Σρέντιγκερ. Ξεκινήσαμε θεωρώντας το απλό σύστημα μιας μη γραμμικής εξίσωσης Σρέντιγκερ η οποία δέχεται σολιτονικές λύσεις και αφού κάναμε διερεύνηση τω λύσεων που δέχεται τα χωρίσαμε σε φωτεινά και σκοτεινά σολιτόνια. Στη συνέχεια εφαρμόσαμε τα ίδια πράγματα την ίδια ακριβώς μεθοδολογία σε ένα συζευγμένο σύστημα εξισώσεων. Έπειτα μελετήσαμε την αλληλεπίδραση των σκοτεινών σολιτονίων παρουσία ασαφειών με τις Μπόζ Αϊνστάιν συμπυκνώσεις και έχοντας παγιδευμένο δυναμικό. Τέλος περιγράψαμε την αλληλεπίδραση σκοτεινού-φωτεινού σολιτονίου δημιουργώντας ένα σύστημα παρουσία διαταραχών και αξιοποιώντας το νέφος ΤF και κάνοντας κατάλληλους μετασχηματισμούς καταλήξαμε σε ένα δραστικό δυναμικό.
description: The aim of the present thesis was to study the dynamics of solitons in coupled system of non linear Schrodinger equation. We started with a simple system of NLS (non linear Schrodinger) equation which accepts solutions of solitons and after the research of the solutions that accepts we separated them in bright and dark solitons. Furthermore we applied the same things, exactly the same method in a coupled system of NLS equations. Then we studied the interaction of dark solitons in the present of Bose Einstein condensates using a trapping potential. In the end we described the interaction of dark-bright solitons by creating a system in the present of perturbations and using the TF cloud and doing suitable transformations we took an effective potential.

description: Neural Module Networks (NMNs) aim at Visual Question Answering (VQA) via composition of modules that tackle a sub-task. NMNs are a promising strategy to achieve systematic generalization, i.e., overcoming biasing factors in the training distribution. However, the aspects of NMNs that facilitate systematic generalization are not fully understood. In this paper, we demonstrate that the degree of modularity of the NMN have large influence on systematic generalization. In a series of experiments on three VQA datasets (VQA-MNIST, SQOOP, and CLEVR-CoGenT), our results reveal that tuning the degree of modularity, especially at the image encoder stage, reaches substantially higher systematic generalization. These findings lead to new NMN architectures that outperform previous ones in terms of systematic generalization.
The measurements of the optical properties of diamond-like carbon thin films by fourier-transform infrared spectroscopy
Creators: name: Xie, Yidan
Publisher: name: University of British Columbia
Year: 2009

description: Infrared reflectance and transmittance measurements of diamond-like carbon thin films grown by d.c. magnetron sputtering were performed at nearly normal incidence, using a Bruker IFS 1 13V Fourier-transform spectrometer. The project was a collaboration with Glenn Clarke, a Ph.D student under the supervision of Dr. R. Parsons. Glenn Clarke grew all of the films and extracted the absorption coefficient from the reflectivity and transmission data, using a matrix method. The spectral features were mainly the broad interference oscillations characteristic of thin films and the absorptions caused by excited vibrational modes. An interband-transition model of n and k, together with a dispersion model, which is a superposition of the background absorption and the vibrational resonances, was used to fit the experimental data and obtain some information about the chemical bonds in these films. It was found that the optical properties of the diamond-like carbon films were strongly dependent on the deposition pressure during the sputtering and any hydrogen incorporation.

description: Η παρούσα εργασία επικεντρώνεται στην έρευνα και εφαρμογή συγκεκριμένης μεθοδολογίας διαχείρισης, μετάπτωσης και μεταφοράς γνωστικού υλικού και δεδομένων ανάμεσα στα LMS συστήματα. Η μεθοδολογία αυτή στηρίζεται στην φιλοσοφία δημιουργίας ενός κοινού format μεταδεδομένων για κάθε λογική οντότητα των LMS συστημάτων, έτσι ώστε με την δυνατότητα εξαγωγής και εισαγωγής δεδομένων στο format αυτό, να επιτυγχάνεται η πλήρης μετάπτωση από ένα LMS σε ένα άλλο. Ένα από τα βασικά προβλήματα και θέματα στην διαχείριση υλικού (content) στα LMS συστήματα είναι η αδυναμία μεταφοράς και ανταλλαγής δεδομένων, λόγω ημιτελούς χαρτογράφησης των προσδιοριστικών χαρακτηριστικών των λογικών οντοτήτων των συστημάτων αυτών. Η εργασία αυτή προτείνει μία «χαρτογράφηση» των οντοτήτων, επισημαίνοντας ποια πρέπει να είναι τα προσδιοριστικά χαρακτηριστικά αυτών, στα σύγχρονα LMS συστήματα. Για το σκοπό της μελέτης όσον αφορά την αποτελεσματικότητας της πρότασης αυτής, έχει δημιουργηθεί μια εφαρμογή με το όνομα LMS.connect, η οποία δημιουργεί και διαχειρίζεται της λογικές οντότητες (ονομάζονται «agents») και μοντελοποιεί τα δεδομένα από τις βάσεις δεδομένων των LMS συστημάτων, πάνω στις οντότητες αυτές. Η μελέτη έγινε πάνω σε 2 δημοφιλή – open source – συστήματα, στο Moodle και στο open eClass.
description: This paper focuses on the research and application of a specific methodology for management, migration and transfer of content and data between LMS platforms. The methodology is based on the philosophy of creating a common metadata format for each logical entity of an LMS system, in order to achieve a complete migration between LMS systems, through import and export. One of the key issues in LMS content migration is the inability to transfer and exchange information through a generic model. The lack of such model and the incomplete mapping of the defined characteristics of LMSes logical entities, leads to incomplete migration solutions provided by specific LMS vendors. This paper proposes a "map" of entities, highlighting what the defining characteristics should be, in contemporary LMS systems. For the purpose of the study over the effectiveness of this proposal, an application has been created (called LMS.connect), which help users to create and manage logical entities (called "agents") models and provides ways to "map" data from the databases of LMS systems over those entities. The study was conducted over 2 popular - open source – systems: Moodle and Open eClass.

description: Ensuring a sustainable future for Open Science (OS) and open access scholarly publishing is imperative to support today’s and tomorrow’s crises. This webinar shines a light on the need for funding OS infrastructure in the context of COVID-19.  While OS infrastructure has been generously funded for years, without more funding, essential services that many of us depend upon are at risk of service degradation, reduced availability and of survival in some cases. Furthermore, much of the infrastructure run by not for-profits is currently free to libraries. However, how long this free service will last unknown since some commercial publishers are diversifying portfolios. An uncomfortable truth is that budgets are now even more strained, and operational and development costs remain in the absence of mid- or long-term funding solutions. OS not-for-profit infrastructure is appealing to academic library directors due to limited financial support. It is crucial that library directors take a leading role in continuing to provide financial support for OS infrastructure, even in such challenging times. Libraries across the world have raised over 2.9 million euros over several years for OS infrastructure, supporting DOAJ, Sherpa Romeo, DOAB, OAPEN, PKP and OpenCitations. However, some of these infrastructures are still far from reaching their targets. A few thousand euros can go a long way. This webinar brings together voices from the library community who have committed to funding OS infrastructure from all regions of Europe. They offer their own perspectives on why funding remains so important to them and their organisations. Attendees learned: About the current SCOSS infrastructures who seek funding, How institutions and library consortia are financially supporting OS infrastructure, Arguments for justifying financial support for OS within your own institution. This webinar is jointly organised by LIBER and SPARC Europe within the framework of SCOSS - Global Sustainability Coalition for Open Science Services, which aims to improve the financial position, enhance resilience, and better ensure OS infrastructure sustainability. Speakers represent OS infrastructures, library directors and consortia who have funded OS infrastructure from different regions of Europe.

description: We investigate the quantum transport through a single-wall carbon nanotube connected to leads in the presence of an external radiation field. We analyze the conductance spectrum as a function of the frequency and strength of the field. We found that above a critical value of the field intensity, an enhancement of the conductance, or suppressed resistance, as a function of the field strength occurs. The conductance increases displaying oscillations which amplitude shows a strong dependence on the field frequency. For low radiation energies in comparison to the lead-CNT coupling energies, the oscillations evolve toward a structure of well defined steps in the conductance. We have shown that in this range of frequencies the field intensity dependence of the conductance can give direct information of single-walled carbon nanotubes energy spectra.

description: The gravitational wave signal generated by global, nonaxisymmetric shear flows in a neutron star is calculated numerically by integrating the incompressible Navier--Stokes equation in a spherical, differentially rotating shell. At Reynolds numbers $\Rey \gsim 3 \times 10^{3}$, the laminar Stokes flow is unstable and helical, oscillating Taylor--Görtler vortices develop. The gravitational wave strain generated by the resulting kinetic-energy fluctuations is computed in both $+$ and $\times$ polarizations as a function of time. It is found that the signal-to-noise ratio for a coherent, $10^{8}$-{\rm s} integration with LIGO II scales as $ 6.5 (Ω_*/10^{4} {\rm rad} {\rm s}^{-1})^{7/2}$ for a star at 1 {\rm kpc} with angular velocity $Ω_*$. This should be regarded as a lower limit: it excludes pressure fluctuations, herringbone flows, Stuart vortices, and fully developed turbulence (for $\Rey \gsim 10^{6}$).
