description: Occultations of the Jovian low frequency radio emissions by the Galilean moons have been observed by the PWS instrument of the Galileo spacecraft. We show that the ExPRES (Exoplanetary and Planetary Radio Emission Simulator) code accurately models the temporal occurrence of the occultations in the whole spectral range observed by Galileo/PWS. This validates of the ExPRES code. The method can be applied for preparing the JUICE moon flyby science operation planning.

description: This work describes a simple agent model for the spread of an epidemic outburst, with special emphasis on mobility and geographical considerations, which we characterize via statistical mechanics and numerical simulations. As the mobility is decreased, a percolation phase transition is found separating a free-propagation phase in which the outburst spreads without finding spatial barriers and a localized phase in which the outburst dies off. Interestingly, the number of infected agents is subject to maximal fluctuations at the transition point, building upon the unpredictability of the evolution of an epidemic outburst. Our model also lends itself to testing vaccination schedules. Indeed, it has been suggested that if a vaccine is available but scarce it is convenient to carefully select the vaccination program to maximize the chances of halting the outburst. We discuss and evaluate several schemes, with special interest on how the percolation transition point can be shifted, allowing for higher mobility without epidemiological impact.

description: This paper proves that the q-model structures of Moore flows and of multipointed $d$-spaces are Quillen equivalent. The main step is the proof that the counit and unit maps of the Quillen adjunction are isomorphisms on the q-cofibrant objects (all objects are q-fibrant). As an application, we provide a new proof of the fact that the categorization functor from multipointed $d$-spaces to flows has a total left derived functor which induces a category equivalence between the homotopy categories. The new proof sheds light on the internal structure of the categorization functor which is neither a left adjoint nor a right adjoint. It is even possible to write an inverse up to homotopy of this functor using Moore flows.

The St. Peter Icon of Dumbarton Oaks Reconsidered
Creators: name: Georgievska-Shine, Aneta
Publisher: name: Digital Repository at the University of Maryland
Year: 1993

description: The thesis concentrates on an icon of st. Peter from
the Dumbarton Oaks Collection. The author reexamines its
present dating to the end of the 13th and beginning of the
14th centuries, and attribution to Macedonia, and suggests
that the icon be seen within the oeuvre of Michael and
Eutychius, the two preeminent artists of that time/ region.
Stylistically, St.Peter is closest to their work of
1314-17, exemplified in the frescoes from the King's Church
in studenica and st. George in staro Nagorichino. Iconographically,
this icon finds a unique parallel in the Church of
Peribleptos, Ochrid (1295), where St. Peter is also shown
with keys around his neck.
Since the proposed attribution falls within the reign
of the Serbian King Milutin (1282-1321), the thesis
considers how the Serbian political predicaments at the time
reflect on st. Peter's image in the Church of the Savior at
Zica, restored between 1309-16, and the Church of the
Annunciation at Gracanica, built between 1311-20. These
churches, like the Ochrid Peribleptos, show the First
Apostle holding a church model above his head.
Both the keys around the neck from the D.O. icon and
Peribleptos, and the churches above St. Peter's head from
Peribleptos, Zica, and Gracanica, indicate a special
emphasis on the role of the First Apostle.
The author further suggests that these images may
reflect the ecclesiastical relationship between the Serbian
and Ochrid Archbishoprics and that the D.O. icon may also be
concerned with issues of church authority.

description: The aim of the present dissertation was the study of community service order as an alternative punishment to prison. First of all, the historical dimension of treatment until the introduction and the adoption of alternatives to custodial penalties was examined. Then we presented the features of community service order among several legal orders. Furthermore, we analyzed the effects of imprisonment in order to prove that community service order is an a viable alternative to custodial penalties. Finally, a separate chapter is about community service order for juvenile offenders due to the specific characteristics of these offenders and the form that is found in the Juvenile Justice.

description: We measured the electronic properties and gas sensing response of nanowires containing segments of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) that were synthesized using anodic aluminum oxide (AAO) membranes. The nanowires have a "striped" structure of gold-PEDOT/PSS-gold and are typically 8 um long (1 um-6 um-1 um for each section, respectively) and 220 nm in diameter. Dielectrophoretic assembly was used to position single nanowires on pre-fabricated gold electrodes. A polymer conductivity of 11.5 +/- 0.7 S/cm and a contact resistance of 27.6 +/- 4 kOhm were inferred from resistance measurements of nanowires of varying length and diameter. When used as gas sensors, the wires showed a resistance change of 10.5%, 9%, and 4% at the saturation vapor pressure of acetone, methanol and ethanol, respectively. Sensor response and recovery were rapid (seconds) with excellent reproducibility in time and across devices. "Striped" template-grown nanowires are thus intriguing candidates for use in electronic nose vapor sensing systems.

Gravitational Fragmentation of Extremely Metal-poor Circumstellar Discs

description: We study the gravitational fragmentation of circumstellar discs accreting extremely metal-poor ($Z \leq 10^{-3}$ Zsun) gas, performing a suite of three-dimensional hydrodynamic simulations using the adaptive mesh refinement code Enzo. We systematically follow the long-term evolution for 2000 years after the first protostar's birth, for the cases of $Z = 0$, $10^{-5}$, $10^{-4}$, and $10^{-3}$ Zsun. We show that evolution of number of self-gravitating clumps qualitatively changes with $Z$. Vigorous fragmentation induced by dust cooling occurs in the metal-poor cases, temporarily providing about 10 self-gravitating clumps at $Z = 10^{-5}$ and $10^{-4}$ Zsun. However, we also show that the fragmentation is a very sporadic process; after an early episode of the fragmentation, the number of clumps continuously decreases as they merge away in these cases. The vigorous fragmentation tends to occur later with the higher $Z$, reflecting that the dust-induced fragmentation is most efficient at the lower density. At $Z = 10^{-3}$ Zsun, as a result, the clump number stays smallest until the disc fragmentation starts in a late stage. We also show that the clump mass distribution also depends on the metallicity. A single or binary clump substantially more massive than the others appear only at $Z = 10^{-3}$ Zsun, whereas they are more evenly distributed in mass at the lower metallicities. We suggest that the disc fragmentation should provide the stellar multiple systems, but their properties drastically change with a tiny amount of metals.

description: Ideal (monodomain) smectic-$A$ elastomers crosslinked in the smectic-$A$ phase are simply uniaxial rubbers, provided deformations are small. From these materials smectic-$C$ elastomers are produced by a cooling through the smectic-$A$ to smectic-$C$ phase transition. At least in principle, biaxial smectic elastomers could also be produced via cooling from the smectic-$A$ to a biaxial smectic phase. These phase transitions, respectively from $D_{\infty h}$ to $C_{2h}$ and from $D_{\infty h}$ to $D_{2h}$ symmetry, spontaneously break the rotational symmetry in the smectic planes. We study the above transitions and the elasticity of the smectic-$C$ and biaxial phases in three different but related models: Landau-like phenomenological models as functions of the Cauchy--Saint-Laurent strain tensor for both the biaxial and the smectic-$C$ phases and a detailed model, including contributions from the elastic network, smectic layer compression, and smectic-$C$ tilt for the smectic-$C$ phase as a function of both strain and the $c$-director. We show that the emergent phases exhibit soft elasticity characterized by the vanishing of certain elastic moduli. We analyze in some detail the role of spontaneous symmetry breaking as the origin of soft elasticity and we discuss different manifestations of softness like the absence of restoring forces under certain shears and extensional strains.

description: Constructing a fault-tolerant quantum computer is a daunting task. Given any design, it is possible to determine the maximum error rate of each type of component that can be tolerated while still permitting arbitrarily large-scale quantum computation. It is an underappreciated fact that including an appropriately designed mechanism enabling long-range qubit coupling or transport substantially increases the maximum tolerable error rates of all components. With this thought in mind, we take the superconducting flux qubit coupling mechanism described in PRB 70, 140501 (2004) and extend it to allow approximately 500 MHz coupling of square flux qubits, 50 um a side, at a distance of up to several mm. This mechanism is then used as the basis of two scalable architectures for flux qubits taking into account crosstalk and fault-tolerant considerations such as permitting a universal set of logical gates, parallelism, measurement and initialization, and data mobility.

description: In this work, we propose a globally optimal joint successive interference cancellation (SIC) ordering and power allocation (JSPA) algorithm for the sum-rate maximization problem in downlink multi-cell non-orthogonal multiple access (NOMA) systems. The proposed algorithm is based on the exploration of base stations (BSs) power consumption, and closed-form of optimal powers obtained for each cell. Although the optimal JSPA algorithm scales well with larger number of users, it is still exponential in the number of cells. For any suboptimal decoding order, we propose a low-complexity near-optimal joint rate and power allocation (JRPA) strategy in which the complete rate region of users is exploited. Furthermore, we design a near-optimal semi-centralized JSPA framework for a two-tier heterogeneous network such that it scales well with larger number of small-BSs and users. Numerical results show that JRPA highly outperforms the case that the users are enforced to achieve their channel capacity by imposing the well-known SIC necessary condition on power allocation. Moreover, the proposed semi-centralized JSPA framework significantly outperforms the fully distributed framework, where all the BSs operate in their maximum power budget. Therefore, the centralized JRPA and semi-centralized JSPA algorithms with near-optimal performances are good choices for larger number of cells and users.

Λόγω του φαινομένου του εντοπισμού Anderson (Anderson localization), οι κανονικοί τρόποι ταλάντωσης σε μονοδιάστατα άτακτα πλέγματα γραμμικών ταλαντωτών είναι εκθετικά εντοπισμένοι. Όταν προστεθεί μη γραμμικότητα στο μοντέλο, τότε προκύπτει το ερώτημα: Θα ενισχύσουν οι χαοτικές διαδικασίες τον εντοπισμό ή θα τον καταστρέψουν; Πρόσφατες προσομοιώσεις επιβεβαιώνουν τη διάχυση ενός αρχικά εντοπισμένου κυματοπακέτου. Σκοπός της παρούσας μελέτης είναι να διαλευκάνει τις δυναμικές διαδικασίες, που οδηγούν σε αυτήν τη συμπεριφορά. Χρησιμοποιώντας αριθμητικές μεθόδους, όπως οι συμπλεκτικοί ολοκληρωτές και η μέθοδος της εφαπτομενικής απεικόνισης (tangent map), δεν παρατηρούμε απλώς ποιοτικά τη διάχυση, αλλά εξάγουμε ποσοτικά αποτελέσματα με τη χρήση δεικτών χαοτικότητας. Για πρώτη φορά παρουσιάζονται συστηματικοί υπολογισμοί εκθετών Lyapunov για τέτοιου είδους συστήματα. Από τα αποτελέσματά μας προκύπτει ότι η παρατηρούμενη χρονική κλίμακα διάδοσης της χαοτικότητας είναι μικρότερη από τις χρονικές κλίμακες διάχυσης του συστήματος, υποστηρίζοντας τις θεωρίες ότι η παρατηρούμενη διάχυση είναι τελικά μια χαοτική διαδικασία.
description: The interplay between non-linearity and disorder has been the subject of many recent studies. Due to Anderson localization, the normal modes of a 1-dimensional disordered lattice of linear oscillators are exponentially localized. When nonlinearities are also added to the model a natural question arises: Will the chaotic processes, induced by the non-linear terms of the equations, enhance the localization or they will destroy it? The latest numerical results confirm a subdiffusive spreading of an initially localized wavepacket. The purpose of this thesis is to try to lighten the dynamics behind the diffusive behaviour. Using innovative numerical techniques, like symplectic integrators and their extension to the tangent map method, not only we qualitatively observe the spreading process, but a quantitative approach is used with the aid of chaos detection indicators. For the first time systematic numerical calculations of finite Lyapunov exponents are reported for such systems. Our findings yield that the chaotic time-scale of the system is shorter than the spreading time scales, supporting the theories that the diffusion is a process driven by chaos.

The Prompt Gamma-Ray and Afterglow Energies of Short-Duration Gamma-Ray Bursts
Creators: name: Berger, E.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I present an analysis of the gamma-ray and afterglow energies of the complete sample of 17 short duration GRBs with prompt X-ray follow-up. I find that 80% of the bursts exhibit a linear correlation between their gamma-ray fluence and the afterglow X-ray flux normalized to t=1 d, a proxy for the kinetic energy of the blast wave ($F_{X,1}~F_{gamma}^1.01). An even tighter correlation is evident between E_{gamma,iso} and L_{X,1} for the subset of 13 bursts with measured or constrained redshifts. The remaining 20% of the bursts have values of F_{X,1}/F_{gamma} that are suppressed by about three orders of magnitude, likely because of low circumburst densities (Nakar 2007). These results have several important implications: (i) The X-ray luminosity is generally a robust proxy for the blast wave kinetic energy, indicating nu_X>nu_c and hence a circumburst density n>0.05 cm^{-3}; (ii) most short GRBs have a narrow range of gamma-ray efficiency, with ~0.85 and a spread of 0.14 dex; and (iii) the isotropic-equivalent energies span 10^{48}-10^{52} erg. Furthermore, I find tentative evidence for jet collimation in the two bursts with the highest E_{gamma,iso}, perhaps indicative of the same inverse correlation that leads to a narrow distribution of true energies in long GRBs. I find no clear evidence for a relation between the overall energy release and host galaxy type, but a positive correlation with duration may be present, albeit with a large scatter. Finally, I note that the outlier fraction of 20% is similar to the proposed fraction of short GRBs from dynamically-formed neutron star binaries in globular clusters. This scenario may naturally explain the bimodality of the F_{X,1}/F_{gamma} distribution and the low circumburst densities without invoking speculative kick velocities of several hundred km/s.

description: The Genomics Coordination Center (Groningen, the Netherlands) has gained broad experience in running complex workflows, in which large datasets are analyzed using heterogeneous computational resources from projects like the Genome of the Netherlands and LifeLines. The primary goal was to analyze large data and deliver results as quick as possible.

Now, sharing analysis protocols between institutions and reproducing analysis results has become an important issue. Setting up an execution environment in a new cluster or grid computational site introduces certain latency to the time needed to obtain results. Furthermore, the executional settings environments can change in computational grids and clusters. Hence, we have considered using the cloud infrastructure to automate setting up and sharing analysis infrastructure.

In this work, we present the complete execution environment for NGS analysis, which can be used out of the box in computational resources based on OpenStack platform. We created a configurable VM with widely used in bioinformatics software, implemented into a single pipeline to analyze NGS data. It starts with BWA aligning the raw data (FASTq), followed by realignment around known indels, quality score recalibration and variant calling using Genome Analysis ToolKit (GATK). Several quality metrics are obtained using picard-tools during data processing, variant calls are annotated using SnpEff and SnpSift tools to aid variant interpretation, producing a tab-­delimited variant file. We use the EasyBuild framework and wget tool to install software and download resources respectively to ensure reproducibility of environment set-­up. This enables users to reproduce installation using pre-­defined easyblocks, which are available in the software repository. Furthermore, the necessary resources are installed by executing a shell script after the VM is initiated. The pipeline is available in the github repository.

To summarize, we have shown how to ensure reproducibility and efficient sharing of NGS analyses with the prepared OpenStack VM, which contains all open-­source software needed for analysis grouped in a single analysis pipeline. This OpenStack VM can also be combined with MOLGENIS database management system via OpenStack API to track executions. Also, all NGS analysis jobs can be generated as scripts from the MOLGENIS-Compute command-­line tool. Scripts can be started manually or via the pre-­installed SLURM scheduler.

description: The hybridization of magnetism and superconductivity has been an intriguing playground for correlated electron systems, hosting various novel physical phenomena. Usually, localized d- or f-electrons are central to magnetism. In this study, by placing a PTCDA (3,4,9,10-perylene tetracarboxylic dianhydride) molecular monolayer on ultra-thin Pb films, we built a hybrid magnetism/superconductivity (M/SC) system consisting of only sp electronic levels. The magnetic moments reside in the unpaired molecular orbital originating from interfacial charge-transfers. We reported distinctive tunneling spectroscopic features of such a Kondo screened pi-electron impurity lattice on a superconductor in the regime of TK>>delta suggesting the formation of a two-dimensional bound states band. Moreover, moiré superlattices with tunable twist angle and the quantum confinement in the ultra-thin Pb films provide easy and flexible implementations to tune the interplay between the Kondo physics and the superconductivity, which are rarely present in M/SC hybrid systems.

description: Ο σκοπός της εργασίας είναι να διερευνήσει την απεικόνιση της χρήσης παράνομων ψυχοτρόπων ουσιών στα ρεμπέτικα τραγούδια της εποχής του μεσοπολέμου που το φαινόμενο αρχίζει να αποκτά μαζικό χαρακτήρα σε κάποια τμήματα του πληθυσμού. Στην εισαγωγή έκρινα σκόπιμο να εξεταστούν τα φαινόμενα της χρήσης και της εξάρτησης μέσα από το πρίσμα των διάφορων θεωριών που βοηθούν στην προσέγγισή τους. Έπειτα να γίνει μια ιστορική αναδρομή της χρήσης στην Ελλάδα και του πλαισίου που συνετέλεσε στην μεταβολή της σε πρόβλημα και εξάρτηση και να διερευνηθεί η ιδιαίτερη φύση του συγκεκριμένου μουσικού είδους και το γεγονός ότι οι ιστορικές συνθήκες ανάδυσης και διάδοσης του συμπίπτουν χρονικά αλλά και κάποιες φορές ταυτίζονται με τις συνθήκες που συντέλεσαν στην εξάπλωση της χρήσης παράνομων ουσιών. Στη συνέχεια χρησιμοποιώντας την ποιοτική μέθοδο ανάλυσης λόγου και εξετάζοντας τα τραγούδια ανά στίχο και στο σύνολο τους, οδηγήθηκα σε ευρήματα και κατέληξα σε συμπεράσματα σχετικά με τις σχέσεις των χρηστών με τον εαυτό τους, τις ουσίες, τις γυναίκες, το χρήμα, τον τζόγο, την αστυνομία και τη φυλακή όπως αυτές παρουσιάζονται στα ρεμπέτικα τραγούδια της εποχής. Η απεικόνιση αποκαλύπτει σε μεγάλο βαθμό τον τρόπο αντιμετώπισης της χρήσης στη συγκεκριμένη εποχή με τις κοινωνικές, πολιτικές, οικονομικές και πολιτιστικές συνθήκες που τη συνοδεύουν.
description: The purpose of this study is to examine the depiction of illicit psychoactive substances in rebetika songs of the period between the wars when the effect begins to acquire a mass character in some parts of the population. In the introduction I deemed it appropriate to examine the phenomena of use and dependence in the light of various theories that help in their approach. Then there will be a throwback of the year in Greece and the context contributed to the change in problem and dependence and to investigate the specific nature of the genre and the fact that the historical conditions of emergence and spread of coincide and sometimes identical the conditions that contributed to the spread of illicit drug use. Then using the qualitative method of discourse analysis and examining songs per verse as a whole, I was led to findings and reached conclusions on relations with the users themselves, substances, women, money, gambling, the police and prison as presented rebetiko songs of the season. The imaging reveals a large degree how to address the use in this era of social, political, economic and cultural conditions that accompany.

description: We consider the detector size, location, depth, background, and radio-purity required of a mid-Pacific deep-ocean instrument to accomplish the twin goals of making a definitive measurement of the electron anti-neutrino flux due to uranium and thorium decays from Earth's mantle and core, and of testing the hypothesis for a natural nuclear reactor at the core of Earth. We take the experience with the KamLAND detector in Japan as our baseline for sensitivity and background estimates. We conclude that an instrument adequate to accomplish these tasks should have an exposure of at least 10 kilotonne-years (kT-y), should be placed at least at 4 km depth, may be located close to the Hawaiian Islands (no significant background from them), and should aim for KamLAND radio-purity levels, except for radon where it should be improved by a factor of at least 100. With an exposure of 10 kT-y we should achieve a 24% measurement of the U/Th content of the mantle plus core. Exposure at multiple ocean locations for testing lateral heterogeneity is possible.

description: Στα πλαίσια της παρούσας διπλωματικής εργασίας εξετάστηκε η σύμβαση εγγυήσεως και η διατήρηση της ευθύνης των εγγυητών. Πιο συγκεκριμένα, εστιάσαμε στον παρεπόμενο χαρακτήρα της σύμβασης εγγύησης και στις συνέπειες που έχει για τον εκάστοτε εγγυητή, η υπαγωγή του πρωτοφειλέτη, σε προπτωχευτικές ή πτωχευτικές διαδικασίες εξυγίανσης αλλά και στην πτώχευση. Για το σκοπό αυτό κρίθηκε σκόπιμο να αναφερθούμε σε κάποιες από τις βασικές αρχές της σύμβασης εγγυήσεως, προκειμένου εν συνεχεία να προσπαθήσουμε να προσεγγίσουμε την εγγύηση, μέσα από τις διατάξεις του ν.3588/2007 (Πτωχευτικός Κώδικας και εφεξής ΠτΚ) και του ν. 3869/2010. Τέλος, η προσέγγιση της ευθύνης των εγγυητών στα πλαίσια των προπτωχευτικών ή πτωχευτικών διαδικασιών εξυγίανσης και της πτώχευσης βασίστηκε στην σύγκριση του ισχύοντος (ΠτΚ) με το προϊσχύον δίκαιο (ν. 1892/1990).
description: In the context of this thesis examined the security agreement and the maintenance responsibility of the guarantors. More specifically, we focused on ancillary warranty contract and on the consequences for the respective guarantor, the inclusion of the debtor, in pre-bankruptcy reorganization or bankruptcy proceedings and also in bankruptcy. For this purpose it is appropriate to mention some of the basic principles of the Convention guarantee, in order to approach the guarantee, through the provisions of n.3588/2007 (Bankruptcy Code and hereafter SRS) and Law 3869 / 2010. Finally, the approach to the liability of the guarantors under the pre- bankruptcy reorganization or bankruptcy proceedings and the bankruptcy was based on the comparison of the current (SRS) with the pre-existing law (Law 1892/1990).
Power, politics and the innovation process: analysis of an organizational field in agriculture

description: An analysis of the organizational field of B.C. agriculture was conducted to explore the politics of the innovation process. Agricultural innovations in organic farming, synthetic agrichemicals and biogenetic engineering were studied at the individual, organizational and interorganizational levels. Research questions regarding the innovation decision—making process, innovation championship, organizational politics, organization theory and interorganizational networks were explored. A total of 137 persons (organic and conventional farmers, BCMAFF employees, farm organization employees) were interviewed in this research study. Data was collected via semi—structured interviews, questionnaires, and analysis of publications to investigate a total of 28 research questions. Similarities and differences between organic and conventional farmers in respect to their socioeconomic characteristics, motivations, actions and environmentalist beliefs were identified. Organic farmers basis for their innovation adoption decisions was found to be largely informed by their environmentalist philosophy whereas the primary motivating factor for conventional farmers was economic rather than ideological. Case studies of 33 farm organizations (20 conventional and 13 organic) were conducted. Organizational fields were found to be defined not only in terms of products, services and geographic location but also in terms of ideology. Within the conventional agriculture organizational field there was a high degree of homogeneity in organizational structures and decision making processes as well as close collaboration with government policy makers. Within the organic agriculture organizational field there was homogeneity in production practices, but heterogeneity in organizational structures, goals and decision making processes based on the radicalness of the environmentalist philosophy of an organization’s membership. The formation and operation of interorganizational networks in each organizational field confirmed previous findings of the critical problems in overorganized and underorganized networks. A longitudinal analysis of organizational politics in the organic agriculture organizational field revealed that institutionalization processes engender political contests among competing interests. The successful championship of an innovative government regulatory system was attributed to the early use of a wide variety of collaborative and competitive political games. Opponents’ efforts to neutralize champions’ escalation of commitment during the later stages of the innovation development process proved to be ineffective.
