description: Με την παρούσα διπλωματική εργασία επιδιώκεται μια θεωρητική και εμπειρική μελέτη των διαπεριφερειακών ανισοτήτων στην επικράτεια της Ευρωπαϊκής Ένωσης και της Ελλάδας ξεχωριστά. Το ερώτημα που τίθεται αφορά την εμφάνιση των διαπεριφερειακών ανισοτήτων στην ευρωπαϊκή και ελληνική επικράτεια και την τυχόν δυνατή εξάλειψη αυτών προς μια πορεία σύγκλισης. Το παραπάνω ερώτημα αποκτά ιδιαίτερη σημασία στις μέρες μας, καθώς η περίοδος οικονομικής κρίσης που διανύουμε, επιδρά αρνητικά στην προσπάθεια οικονομικής ολοκλήρωσης, τόσο της Ευρωπαϊκής Ένωσης όσο και στο εσωτερικό κάθε χώρας ξεχωριστά. Τα εμπειρικά ευρήματα της μελέτης της περίπτωσης της Ελλάδας, της παρούσης διπλωματικής εργασίας, οδηγούν στο συμπέρασμα πως στο εσωτερικό του ελλαδικού χώρου εμφανίζονται σημαντικές διαρθρωτικές ανισότητες οι οποίες λειτουργούν κατασταλτικά στην πορεία σύγκλισης μεταξύ των ελληνικών περιφερειών. Επομένως, κρίνεται ως απαραίτητη προϋπόθεση για την επίτευξη συγκλίνουσας συμπεριφοράς μεταξύ των ελληνικών περιφερειών, η εξάλειψη ή έστω η εξισορρόπηση των όποιων διαρθρωτικών διαπεριφερειακών ανισοτήτων μεταξύ τους.
description: Τhis thesis is a theoretical and empirical study of regional disparities in the European Union and Greece alone. The question concerns the emergence of regional disparities in the European and Greek territory and any possible way to eliminate such an important issue. The above question is particularly important nowadays, as the emergence of four-year period of economic crisis, has a negative impact on economic integration effort, both in the European Union and within each country. The empirical findings in the case of Greece, in this thesis, suggest that within the Greek territory appear important structural inequalities that operate repressively towards a convergence path among Greek regions. Therefore, it is a prerequisite to try to eliminate any regional disparities and achieve structural balance between Greek regions in order to achieve convergent behavior among them.

description: Context. The chemical evolution of formamide (HCONH2), a molecule of astrobiological interest that has been tentatively identified in interstellar ices and in cometary coma, has been studied in laboratory under simulated astrophysical conditions such as ion irradiation at low temperature. Aims. To evaluate the abundances of formamide observed in space or in laboratory, the integrated absorbances for all the principal IR features of frozen amorphous pure formamide deposited at 20 K were measured. Further evidence that energetic processing of ices occurring in space is extremely relevant both to astrochemistry and to astrobiology has been found, showing that new molecular species are synthesized by ion irradiation at a low temperature. Methods. Pure formamide were deposited at 20 K and IR transmission spectra measured for different ice thicknesses. The ice thickness was derived by looking at the interference pattern (intensity versus time) of a He-Ne laser beam reflected at an angle of 45 deg by the vacuum-film and film-substrate interfaces. Samples of formamide ice were irradiated with 200 keV H+ ions and IR spectra recorded at different ion fluences. Results. New molecules were synthesized among which are CO, CO2, N2O, isocyanic acid (HNCO), and ammonium cyanate (NH4+OCN-). Some of these species remain stable after warming up to room temperature.

description: We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought correlations between the Vela's X-ray emission and radio arrival times on a pulse by pulse basis. At a confidence level of 99.8% we have found significantly higher flux density in Vela's main X-ray peak during radio pulses that arrived early. This excess flux shifts to the 'trough' following the 2nd X-ray peak during radio pulses that arrive later. Our results suggest that the mechanism producing the radio pulses is intimately connected to the mechanism producing X-rays. Current models using resonant absorption of radio emission in the outer magnetosphere as a cause of the X-ray emission are explored as a possible explanation for the correlation.

description: We calculate isotope mass shift for several light ions using Dirac wave functions and mass shift operator with relativistic corrections of the order of $(αZ)^2$. Calculated relativistic corrections to the specific mass shift vary from a fraction of a percent for Carbon, to 2% for Magnesium. Relativistic corrections to the normal mass shift are typically smaller. Interestingly, the final relativistic mass shifts for the levels of one multiplet appear to be even closer than for non-relativistic operator. That can be important for the astrophysical search for possible $α$-variation, where isotope shift is a source of important systematic error. Our calculations show that for levels of the same multiplet this systematics is negligible and they can be used as probes for $α$-variation.

description: We study the holographic principle of the two-point function in the case of a spinning string in the AdS/CFT correspondence. Following the general method proposed by Yoneya et al. for the bulk-boundary correspondence in the large $J$ limit, we study the spinning string solution which starts and ends at the boundary. We then show that the spinning string solution directly gives a two-point function that is consistent with the spin chain picture in gauge theory.

description: In the last decade, the uptake of information and communication tech-nologies and the advent of mobile internet, resulted in improved connectivity and penetrated different fields of application. In particular, the adoption of the mobile devices is expected to reform the provision and delivery of healthcare, overcoming geographical, temporal, and other organizational limitations. mHealth solutions are able to provide meaningful clinical information allowing effective and efficient management of chronic diseases, such as heart failure. A variety of multi-paramet-ric data can be collected, such as lifestyle, sensor/biosensor and health-related in-formation. The analysis of these data empowers patients and the involved ecosys-tem actors, improves the healthcare delivery and facilitates the transformation of existing health services. The aim of this study is to provide an overview of (i) the current practice in the management of heart failure, (ii) the available mHealth solu-tions, either in the form of the commercial applications, research projects and re-lated studies, (iii) the several challenges related to the patient and healthcare pro-fessionals’ acceptance, the payer and provider perspective and the regulatory constraints.

description: A number of characteristics of integrable nonlinear partial differential equations (PDE's) for classical fields are reviewed, such as Backlund transformations, Lax pairs, and infinite sequences of conservation laws. An algebraic approach to the symmetry problem of PDE's is described, suitable for PDE's the solutions of which are non-scalar fields (e.g., are in the form of matrices). A method is proposed which, in certain cases, may "unify" the symmetry and integrability properties of a nonlinear PDE. Application is made to the self-dual Yang-Mills equation and the Ernst equation of General Relativity.

description: This study discusses how kitsch, a word coined only recently, has permeated modern life to such an extent that has become ubiquitous. Being entangled in the processes of industrialization and mechanical reproduction, kitsch, with its penchant for repetition, artifice, sentimentality and conservativism, emerges as a dominant feature of modernity that shapes human experience of both pleasure and terror. Within the context of the growing commercialization of society, it seems that with a twist, all things can be legitimately kitschified, be it pleasure or horror. The research paper focuses on two extreme examples of kitschification – a horrifying one, as 9/11 is, and a pleasing one, the American musical, – which points to precisely the potential of mass culture to turn everything it touches into kitsch, as if it were a warped King Midas. The political implications of kitsch and issues of ideology also constitute a focal point of this paper.
description: Το θέμα αυτής της μελέτης είναι το κιτς, μια λέξη που μόλις πρόσφατα έχει αρχίσει να χρησιμοποιείται, και πως έχει διεισδύσει στη σύγχρονη ζωή σε τέτοιο βαθμό που έχει γίνει πανταχού παρόν. Όντας συνδεδεμένο με τις διαδικασίες της βιομηχανοποίησης και της μηχανικής παραγωγής, το κιτς, με την τάση του για επανάληψη, τέχνασμα, συναισθηματισμό και συντηρητισμό, αναδύεται ως ένα κυρίαρχο χαρακτηριστικό της σύγχρονης κοινωνίας που διαμορφώνει την ανθρώπινη εμπειρία τόσο της ευχαρίστησης όσο και του φόβου. Πράγματι, στα πλαίσια της συνεχώς αυξανόμενης εμποροποίησης της κοινωνίας, φαίνεται ότι με μια παραλλαγή όλα τα πράγματα μπορούν εύλογα να «κιτσοποιηθούν», είτε πρόκειται για ευχαρίστηση είτε για τρόμο. Η παρούσα εργασία επικεντρώνεται σε δύο ακραία παραδείγματα «κιτσοποίησης». Στο ένα άκρο είναι το φριχτό γεγονός της ενδεκάτης Σεπτεμβρίου και ο ρόλος του κιτς στο τρόπο που παρουσιάστηκε στο πλατύ κοινό, ενώ στο άλλο άκρο βρίσκεται η ευχαρίστηση που προσφέρουν διασκεδάσεις όπως το Αμερικανικό μιούζικαλ, στο οποίο το κιτς αποτελεί αναπόσπαστο κομμάτι. Η χρήση του κιτς σε δυο τόσο ακραίες εκφάνσεις της ανθρώπινης δραστηριότητας δείχνει ακριβώς αυτήν την ικανότητα της μαζικής κουλτούρας να μετατρέπει οτιδήποτε αγγίζει σε κιτς, σαν άλλος στρεβλωμένος βασιλιάς Μίδας. Η σχέση του κιτς με την πολιτική καθώς και θέματα ιδεολογίας επίσης αποτελούν σημεία αναφοράς αυτής της εργασίας.
Where have all the flowers gone? Searching for answers in contemporary practice
Creators: name: Forsyth, Kelley Jean

description: Even though we, the human species, have a deeply rooted connection to flowers, a prejudice against them holds sway in contemporary landscape architectural practice. These prevailing trends to suppress the expression of flowers denies the profession many opportunities. The most obvious is a loss of color, fragrance and texture; however, flowers also tie into two issues important of Landscape Architecture – environmental sustainability and social justice. By foregrounding flowers in landscape design, the profession can engage in mutability, stewardship and habitat reclamation—concepts central in the quest for addressing issues of environmental sustainability. Because of our universal love of flowers, the lack of flowers in a professionally designed landscape gives rise to discussions of for who and how we design public spaces, issues that must be resolved in the quest for social justice. The first chapter of this thesis reviews the winning projects for the American Society of Landscape Architecture Professional Awards. This analysis provides convincing evidence that a persistent marginalization of flowers exists in firms’ depictions of their projects. Three methods of dismissal are identified. Each method, defined as the “green” flower, the “gray” flower, and the “brown” flower, elicits discussions exploring different facets of this foundational prejudice. The second chapter reviews examples of flowers in the modern landscape. The parties responsible for their presence range from bereaved citizens to the large landscape architectural firm Turenscape and horticultural teams responsible for three of America’s largest perennial public gardens. This chapter demonstrates that perennials not only offer color, texture, and fragrance but through their constant cycling through senescence and rebirth encourages an iterative process or systems–led design methodology. The third chapter, the design component of the thesis, describes my personal journey, which led to my commitment to invent teaching methods that encourage the creative expression of a community of people while preserving the important contribution of the principal designer. In this case, teaching students flower garden design through an approach entitled “The Edible Meadow.” It was designed like a game, with instructions to read and rules to follow, broke down the complicated process of flower garden design into a series of steps. Even though the students’ projects were designed within rigorous parameters, their final results were varied, expressive, and beautiful. This thesis was instigated by the desire to see more flowers in the public landscape. Ultimately, the research revealed that the presence of flowers in a landscape represents much more. This thesis is a call for landscape architecture to expand its discourse and give credence to voices previously unheard.
A better false discovery rate controlling procedure for identifying key functional genes in gene set analysis

description: Gene set analysis (GSA) methods, which are used to facilitate biological interpretation of the expression data, can determine statistically significant gene sets (SSGSs) without the need for determination of differentially expressed genes (DEGs). Therefore, the methods can detect subtle but coordinated expression changes in functionally related genes unlike overrepresentation analysis of DEGs. Although this is an advantage of the GSA methods, to identify DEGs in SSGSs is a challenging task, because the DEGs in SSGSs are likely to contribute to the functional differences between the sample groups and thus are biologically important.

 The leading-edge subsets in Gene Set Enrichment Analysis are similar to the DEGs in SSGSs, however, the subsets are determined by ad hoc criteria and may contain many non-DEGs. This problem can be resolved by controlling the overall false discovery rate (FDR) when testing multiple gene sets and genes, however, which causes low sensitivity and inflexibility of the identification of the DEGs in SSGSs.

 In order to sensitively and flexibly identify the DEGs in SSGSs, we propose an approach that controls the FDR of the DEGs in each SSGS. This approach was able to sensitively detect DEGs that show coordinated expression changes in functionally related genes. We demonstrate that the proposed FDR controlling procedure has several advantages in identification of the DEGs in SSGSs compared with the approach using the conventional FDR controlling procedure, and that the subsequent clustering analysis based on the DEGs in SSGSs is appropriate for identifying biologically important genes in GSA.

description: Are the e-prints (electronic preprints) from the arXiv repository being used instead of the journal articles? In this paper we show that the e-prints have not undermined the usage of journal papers in the astrophysics community. As soon as the journal article is published, the astronomical community prefers to read the journal article and the use of e-prints through the NASA Astrophysics Data System drops to zero. This suggests that the majority of astronomers have access to institutional subscriptions and that they choose to read the journal article when given the choice. Within the NASA Astrophysics Data System they are given this choice, because the e-print and the journal article are treated equally, since both are just one click away. In other words, the e-prints have not undermined journal use in the astrophysics community and thus currently do not pose a financial threat to the publishers. We present readership data for the arXiv category "astro-ph" and the 4 core journals in astronomy (Astrophysical Journal, Astronomical Journal, Monthly Notices of the Royal Astronomical Society and Astronomy & Astrophysics). Furthermore, we show that the half-life (the point where the use of an article drops to half the use of a newly published article) for an e-print is shorter than for a journal paper.

description: The strong coupling constants are basic quantities that carry information of the strong interactions among the baryon and meson multiplets as well as information on the natures and internal structures of the involved hadrons. These parameters enter to the transition matrix elements of various decays as main inputs and they play key roles in analyses of the experimental data including various hadrons. We determine the strong coupling constants among the doubly heavy spin-$ 3/2 $ baryons, $Ξ^*_{QQ'} $ and $Ω^*_{QQ'}$, and light pseudoscalar mesons, $π$, $K$ and $η$, using the light-cone QCD. The values obtained for the strong coupling constants under study may be used in construction of the strong potentials among the doubly heavy spin-3/2 baryons and light pseudoscalar mesons.

description: Cloud computing is an emerging technology that gains wide inﬂuence on IT systems. The main value proposition of Cloud Computing is to provide the clients with a cost-effective, convenient means to consume the amount of IT resources that is actually needed for the client, while better resource utilization of existing infrastructure is achieved through careful selection of the number of servers. However in a massive scale database maximizing parallelism is not the only issue for performance. This thesis focuses on the importance of taking client’s service limitations into account while trying to achieve the maximum degree of parallelism. More specifically, a simulation of an algorithm for determining the number of servers executing parallel range queries is presented in accordance with a paper referring to parallelizing distributed range queries[1]. With the help of a simulator programmed in Java , we are trying to investigate the impact of the number of servers to the overall performance of the system. We present analytical results of the execution of the simulation in a number of cases, as well as experimental illustrations.

description: We report the first experiential observation and theoretical analysis of the new phenomenon of planar chiral circular conversion dichroism, which in some aspects resembles the Faraday effect in magnetized media, but does not require the presence of a magnetic field for its observation. It results from the interaction of an electromagnetic wave with a planar chiral structure patterned on the sub-wavelength scale, and manifests itself in asymmetric transmission of circularly polarized waves in the opposite directions through the structure and elliptically polarized eigenstates. The new effect is radically different from conventional gyrotropy of three-dimensional chiral media.

description: Widely used traditional supervised deep learning methods require a large number of training samples but often fail to generalize on unseen datasets. Therefore, a more general application of any trained model is quite limited for medical imaging for clinical practice. Using separately trained models for each unique lesion category or a unique patient population will require sufficiently large curated datasets, which is not practical to use in a real-world clinical set-up. Few-shot learning approaches can not only minimize the need for an enormous number of reliable ground truth labels that are labour-intensive and expensive but can also be used to model on a dataset coming from a new population. To this end, we propose to exploit an optimization-based implicit model agnostic meta-learning (iMAML) algorithm under few-shot settings for medical image segmentation. Our approach can leverage the learned weights from diverse but small training samples to perform analysis on unseen datasets with high accuracy. We show that, unlike classical few-shot learning approaches, our method improves generalization capability. To our knowledge, this is the first work that exploits iMAML for medical image segmentation and explores the strength of the model on scenarios such as meta-training on unique and mixed instances of lesion datasets. Our quantitative results on publicly available skin and polyp datasets show that the proposed method outperforms the naive supervised baseline model and two recent few-shot segmentation approaches by large margins. In addition, our iMAML approach shows an improvement of 2%-4% in dice score compared to its counterpart MAML for most experiments.

description: Recently a conformally invariant action describing the Wilson-Fischer fixed point in $D=4-ε$ dimensions in the presence of a {\em finite} UV cutoff was constructed \cite{Dutta}. In the present paper we construct two composite operator perturbations of this action with definite scaling dimension also in the presence of a finite cutoff. Thus the operator (as well as the fixed point action) is well defined at all momenta $0\leq p\leq \infty$ and at low energies they reduce to $\int_x ϕ^2$ and $\int _x ϕ^4$ respectively. The construction includes terms up to $O(\lamda^2)$. In the presence of a finite cutoff they mix with higher order irrelevant operators. The dimensions are also calculated to this order and agree with known results.

description: The Atacama Large Millimeter/submillimeter Array (ALMA) combines large collecting area and location on a high dry site to provide it with unparalleled potential for sensitive millimeter/submillimeter spectral line observations. Its wide frequency coverage, superb receivers and flexible spectrometer will ensure that its potential is met. Since the 1999 meeting on ALMA Science\cite{RefA}, the ALMA team has substantially enhanced its capability for line observations. ALMA's sensitivity increased when Japan joined the project, bringing the 16 antennas of the Atacama Compcat Array (ACA), equivalent to eight additional 12m telescopes. The first four receiver cartridges for the baseline ALMA (Japan's entry has brought two additional bands to ALMA's receiver retinue) have been accepted, with performance above the already-challenging specifications. ALMA's flexibility has increased with the enhancement of the baseline correlator with additional channels and flexibility, and with the addition of a separate correlator for the ACA. As an example of the increased flexibility, ALMA is now capable of multi-spectral-region and multi-resolution modes. With the former, one might observe e.g. four separate transitions anywhere within a 2 GHz band with a high resolution bandwidth. With the latter, one might simultaneously observe with low spectral resolution over a wide bandwidth and with high spectral resolution over a narrow bandwidth; this mode could be useful for observations of pressure-broadened lines with narrow cores, for example. Several science examples illustrate ALMA's potential for transforming millimeter and submillimeter astronomy.

Однако существует мнение, что личностные качества человека не влияют на его продуктивность. Важными считаются лишь знания, опыт и адаптационные возможности. В статье вы узнаете об исследованиях и выводах, подытоживающих этот вопрос.The paper considers the corporate culture that factors influence the motivation of employees. There are also examples that describe how to increase the productivity of the working team and how to bring it together. Additionally, we consider a version with tests for determining personality, which, in theory, are ways to predict human behavior at work. However, there is an opinion that the personal qualities of a person do not affect his productivity. Only knowledge, experience and adaptive capabilities are considered important. In the article you will learn about the research and conclusions summarizing this question.

description: The scientific literature is a rich resource for information retrieval on the biological knowledge. Nevertheless, the unstructured textual data in the research articles makes it difficult to access the information with computer-aided systems. Text-mining is one of the solution that can transform unstructured information in the text into database content, and most of the approaches are based on the machine learning models. Since these approaches require high-dimensional features, the performance of the model is heavily dependent on the selection of features. However, it is usually difficult and labor-intensive to choose good features, because feature extraction requires prior knowledge and ingenuity of human experts. Here, we suggest a novel framework to extract biological relations from the texts by using hierarchical text features that enhance the effectiveness of relation extraction model.
The proposed framework is composed of two parts, node and edge detection, using deep belief networks. Each part is based on the hierarchical text features learned by Gaussian-Bernoulli restricted Boltzmann machine (GBRBM). In this work, we performed gene-cancer relation extraction task as a pilot study. The classification model was trained based on both GE09 corpus from BioNLP’09 Shared Task and CoMAGC corpus. The results show that our model achieved better performance than other handcrafted feature-based approaches. The evaluation results suggest that deep belief networks offers the optimized and generalized hierarchical text features for the large-scale text mining.
Pardesan Ka Kam: an essay on Punjabi-Sikh women cannery workers in Northern British Columbia
Creators: name: Pannun, Amarjit Kaur
Publisher: name: University of British Columbia
Year: 2009

description: This essay is an ethnographic account of the lives of Punjabi Sikh women cannery workers in northern British Columbia. Using the concept of difference as an analytical tool, I am extending the analysis beyond the intersections of the differences of race, class, and gender to include regional, ethnic, age and caste variations among the members of this community in order to illustrate the complexities of being a South Asian Canadian woman. By employing individual socio-histories and narratives based on work life, my descriptions revolve around the difficult and rewarding aspects of being an immigrant in the larger Canadian context. As well, I am describing the contradictions and tensions present in raising children in the West while continuing to be a member of an immigrant community which bases some of its norms and accepted behaviours on a displaced Punjabi context.

Solving Fredholm second-kind integral equations with singular right-hand sides on non-smooth boundaries
Creators: name: Helsing, Johan

Publisher: name: arXiv

Subjects: subject: Numerical Analysis (math.NA)

subject: 31A10, 45B05, 45E99, 65R20

description: A numerical scheme is presented for the solution of Fredholm second-kind boundary integral equations with right-hand sides that are singular at a finite set of boundary points. The boundaries themselves may be non-smooth. The scheme, which builds on recursively compressed inverse preconditioning (RCIP), is universal as it is independent of the nature of the singularities. Strong right-hand-side singularities, such as $1/|r|^α$ with $α$ close to $1$, can be treated in full machine precision. Adaptive refinement is used only in the recursive construction of the preconditioner, leading to an optimal number of discretization points and superior stability in the solve phase. The performance of the scheme is illustrated via several numerical examples, including an application to an integral equation derived from the linearized BGKW kinetic equation for the steady Couette flow.

Detection of Changepoints in Ocean Time Series
Creators: name: Kaderli, Severin
name: Frölicher, Thomas L.

Publisher: name: Zenodo
Year: 2020

description: The aim of this thesis is to analyze climate time series for abrupt changes.
 The time series are based on data provided by simulations of the Earth
 System Model GFDL ESM2M and consist of a historical period and
 a Representative Concentration Pathway (RCP8.5) period, where high
 emissions of greenhouse gases are assumed. The annual means of the
 four ocean variables sea surface temperature, sea ice concentration, net
 primary production of phytoplankton, and surface partial CO2 pressure
 are analyzed for abrupt changes. The analysis is based on the R package
 EnvCpt, which is designed to detect structural changes in climate and
 environment time series. Using post-processing R scripts, the EnvCpt
 output is filtered and presented in three different spatial plots. Several regions
 showing abrupt changes either caused by long-term shifts throughout
 the historical period or caused by changes due to the RCP8.5 period
 could be identified. The results are compared to the ones obtained by
 Drijfhout et al. (2015), who also analyzed climate time series for abrupt
 changes. With toy data, some limitations of EnvCpt are recognized and
 some recommendations for the use of EnvCpt are given.
