description: The deviations of non-linear perturbations of black holes from the linear case are important in the context of ringdown signals with large signal-to-noise ratio. To facilitate a comparison between the two we derive several results of linear perturbation theory in coordinates which may be adopted in numerical work. Specifically, our results are derived in Kerr-Schild coordinates adjusted by a general height function. In the first part of the paper we address the questions: for an initial configuration of a massless scalar field, what is the amplitude of the excited quasinormal mode (QNM) for any observer outside outside the event horizon, and furthermore what is the resulting tail contribution? This is done by constructing the full Green's function for the problem with exact solutions of the confluent Heun equation satisfying appropriate boundary conditions. In the second part of the paper, we detail new developments to our pseudospectral numerical relativity code bamps to handle scalar fields. In the linear regime we employ precisely the Kerr-Schild coordinates treated by our previous analysis. In particular, we evolve pure QNM type initial data along with several other types of initial data and report on the presence of overtone modes in the signal.

description: Recently, in search of new approaches to teaching and upbringing modern schoolchildren in pedagogical research, scientists increasingly turn to the consideration of such a concept as strategy. This expands the research space and thus allows, on the one hand, to consider the types and technologies of teaching in the context of a certain strategy, and on the other hand, to develop new strategies for teaching and upbringing. The article is devoted to the consideration of the problem of organizing collaborative learning in a modern school as a new approach to teaching and upbringing students.
India's Biodiversity Conservation Responses to the UN's Sustainable Development Goals: Are they Adequate?

description: India has drawn up plans for it to contribute to the fulfilment of the UN’s Global Agenda 2030 for sustainable development. This chapter focuses on India’s plans for fostering biodiversity conservation in relation to sustainable development goal 15 of this agenda. The aim of SDG15 is to conserve natural ecosystems and life (biodiversity) on land. As noted in this chapter, there is a lack of clarity in Global Agenda 2030 about what ecosystems and components of biodiversity are worthy of preservation. Also the concept of sustainable development is not well defined. Therefore, Global Agenda 2030 gives individual nations considerable leeway in applying these objectives. Furthermore, the targets associated with the UN’s SD goals are ‘fuzzy’ and individual nations are at liberty to decide which targets to pursue. India has selected only three of the twelve UN targets as a part of its contribution to satisfying SDG15, and these are only partly covered by its planning specifications. The reasons for India’s choice and the limitations of its choice are discussed. Also the implications for biodiversity conservation of India’s other SD targets (e.g. those pertaining to water and food supplies) are analyzed and deficiencies are noted. It is contended that India’s SD responses to Global Agenda 2030 reflect the ‘fuzziness’ of the agenda itself. There is a real risk that India will not meet its conservation targets and significantly improve the state of its environment by 2030. It is predicted that India is unlikely to follow a ‘green’ path policy in order to achieve sustainable development by 2030 given that a pro-economic growth climate is likely to prevail politically for some time yet in India.

description: This work presents new Gaussian single- and double-zeta basis sets optimized for stochastic density functional theory (sDFT) using real-space auxiliary grids. Previous studies showed standard basis sets like STO-3G and 6-31G are sub-optimal for this approach. Our basis-set's Gaussian-type orbitals (GTOs) resemble norm-conserving pseudo-orbitals for H, C, N, O, F, and Si, but minimize real-space and momentum-space support. These basis sets achieve accuracy comparable to established sets while offering improved efficiency for sDFT calculations with auxiliary grids.

description: For an irreducible dual pair $(G, G') \in Sp(W)$ with one member compact and two representations $Π\leftrightarrow Π'$ appearing in the Howe duality, we give an expression of the character $Θ_{Π'}$ of $Π'$ via the character of $Π$. We make computations for the dual pair $(G = U(n, \mathbb{C}), G' = U(p, q, \mathbb{C}))$, which are explicit in low dimensions. For $(G = U(1, \mathbb{C}), G' = U(1, 1, \mathbb{C}))$, we verify directly a result of H. Hecht saying that the character has the same value on both Cartan subgroups of $G'$.

description: We study how the work effort and output of non-migrants in a village economy are affected when a member of the village population migrates. Given that individuals dislike low relative income, and that migration modifies the social space of the non-migrants, we show why and how the non-migrants adjust their work effort and output in response to the migration generated change in their social space. When migration is negatively selective such that the least productive individual departs, the output of the non-migrants increases. While as a consequence of this migration statically calculated average productivity rises, we identify a dynamic repercussion that compounds the static one.

description: The quantum correlations between the beams generated by polariton pair scattering in a semiconductor microcavity above the parametric oscillation threshold are computed analytically. The influence of various parameters like the cavity-exciton detuning, the intensity mismatch between the signal and idler beams and the amount of spurious noise is analyzed. We show that very strong quantum correlations between the signal and idler polaritons can be achieved. The quantum effects on the outgoing light fields are strongly reduced due to the large mismatch in the coupling of the signal and idler polaritons to the external photons.

description: We discuss the problem of a spin 1/2 impurity immersed in a spin S magnetically ordered background. We show that the problem maps onto a generalization of the dissipative two level system (DTLS) with two independent heat baths, associated with the Goldstone modes of the magnet, that couple to different components of the impurity spin operator. Using analytical perturbative renormalization group (RG) methods and accurate numerical renormalization group (NRG) we show that contrary to other dissipative models there is quantum frustration of decoherence and quasi-scaling even in the strong coupling regime. We make predictions for the behavior of the impurity magnetic susceptibility that can be measured in nuclear magnetic resonance (NMR) experiments. Our results may also have relevance to quantum computation.

Εβδομήντα έξι νεαροί ποδοσφαιριστές από ακαδημία ποδοσφαίρου του Κιλκίς συμμετείχαν εθελοντικά στη συγκεκριμένη μελέτη και πραγματοποίησαν τη δοκιμασία αξιολόγησης της ικανότητας αλλαγής κατεύθυνσης 505 και για τις δύο πλευρές, το σπριντ 20 m και το κατακόρυφο άλμα με ταλάντευση, τόσο με τα δύο πόδια, όσο και με το κάθε πόδι χωριστά. Σημαντικές ασυμμετρίες βρέθηκαν τόσο στον χρόνο ολοκλήρωσης της δοκιμασίας 505, όσο και στο έλλειμμα της αλλαγής κατεύθυνσης στους νεαρούς ποδοσφαιριστές. Με βάση τις ασυμμετρίες του ελλείμματος τη αλλαγής κατεύθυνσης 20 ποδοσφαιριστές εμφάνισαν ασυμμετρίες μεγαλύτερες του 10%, ενώ με βάση τις ασυμμετρίες του χρόνου ολοκλήρωσης της αλλαγής κατεύθυνσης μόνο ένας ποδοσφαιριστής εμφάνισες μεγαλύτερες ασυμμετρίες του 10%. H ωρίμανση δεν επιδρά στο δείκτη ασυμμετρίας του 505 και του ελλείμματος της αλλαγής κατεύθυνσης. Συμπερασματικά, παρατηρείται καλύτερη επίδοση στη μία πλευρά όσον αφορά την ικανότητα αλλαγής κατεύθυνσης στους νεαρούς ποδοσφαιριστές. Η ωρίμανση ωστόσο δε φαίνεται να διαφοροποιεί τα ποσοστά των ασυμμετριών της αλλαγής κατεύθυνσης στους νεαρούς ποδοσφαιριστές, με τις ασυμμετρίες πιθανώς να δημιουργούνται από πολύ μικρή ηλικία
description: The aim of the thesis was to evaluate change-of-direction ability performance, to identify asymmetries based on change-of-direction deficit and to examine the effect of maturation on asymmetries. Seventy-six young soccer players from a soccer academy of Kilkis region performed 505 for both left and right limbs, 20 m sprint and bilateral and unilateral countermovement jump. Significant differences were revealed between dominant (D) and non-dominant (ND) directions for 505 and change-of-direction deficit. Based on change-of-direction deficit 20 soccer players had asymmetries greater than 10%, in contrast to 505 in which only one soccer player had greater asymmetries than 10%. Neither 505 asymmetry index nor change-of-direction deficit index are influenced by maturation. In conclusion, there is directional dominance on change-of-direction ability in young soccer players. However, maturation has no effect on the asymmetries that young soccer players display in 505 completion time and change-of-direction deficit. It seems logical, that these asymmetries are established from a very young age

Επιπλέον παρουσιάζεται το πολιτιστικό απόθεμα της περιοχής και το πώς αυτό μπορεί να συμβάλει στην ανάπτυξη εναλλακτικών μορφών τουρισμού όπως είναι ο θρησκευτικός τουρισμός, ο οικοτουρισμός και ο αγροτουρισμός, οι οποίες μπορούν να συμβάλουν στην τοπική ανάπτυξη και την ενίσχυση της τουριστικής εικόνας της Σάμου. Τέλος, γίνεται μια αναφορά στη σημαντικότητα της συνεργασίας του δημόσιου και του ιδιωτικού τομέα στον τουρισμό και ακολουθούν τα τελικά συμπεράσματα.
description: In the present thesis the case of Samos island is studied and how its cultural reserve contributes to the further development of the place by promoting tourism and its alternative forms. Initially, there is a review of the history of tourism worldwide, but also a report specifically about the image of tourism in Greece. This is followed by a development of the terms "sustainable tourism development" and "carrying capacity". After that, a short history of the place is presented and then individual details are presented. These concern the demographic data, the accessibility as well as the demand and supply of Samos as a tourist destination. In a next section, the concept of a tourist area cycle of evolution is analyzed and in addition, the types of alternative tourism as established today are presented. The next section lists the types of alternative tourism and how cultural tourism can help to promote other forms of alternative tourism such as religious tourism, ecotourism and rural tourism, which can contribute to local development and enhance the tourist image of Samos. Finally, a reference is made to the importance of public and private partnership in tourism and the final conclusions follow.

description: We study the space-time symmetries of the actions obtained by expanding the action for a massive free relativistic particle around the Galilean action. We obtain all the point space-time symmetries of the post-Galilean actions by working in canonical space. We also construct an infinite collection of generalized Schrödinger algebras parameterized by an integer $M$, with $M=0$ corresponding to the standard Schrödinger algebra. We discuss the Schrödinger equations associated to these algebras, their solutions and projective phases.

description: We study the perturbative Odderon in the quasidiffractive process gamma(*) gamma(*) to eta_c eta_c. At high energies this process is dominated by Odderon exchange and can be viewed as the theoretically cleanest test of the perturbative Odderon. We calculate the differential and total cross section, as well as the dependence on the energy and on the photon virtualities taking into account the effects of resummation of logarithms of the energy. The results are compared with those obtained with a simple exchange of three noninteracting gluons. We present the expected cross section for this process at a future Linear Collider and discuss implications for other processes involving the perturbative Odderon.

title: Restriction Fragment Polymorphisms in Candidate Genes Associated with Hypertension
Creators: name: Barley, Jacqueline

description: This thesis describes an investigation of the role of genetic variation and its association with hypertension. Using molecular biology techniques it is possible to analyse DNA from subjects and distinguish variants of genes that might be involved in blood pressure regulation as potential predictors of essential hypertension. Restriction fragment length polymorphisms (RFLPs) at the gene loci for renin, atrial natriuretic peptide, glucocorticoid receptor and kallikrein have been identified and their frequency determined in three different study groups to establish an association with blood pressure. Measurement of renin, atrial natriuretic peptide and other physiological parameters associated with blood pressure was carried out on selected individuals, and the results correlated with RFLPs. The main conclusions from the study were:- 1. There was no significant association of RFLPs with blood pressure. 2. There was a striking and significant ethnic difference for several of the RFLPs studied. 3. There was no association of physiological measurements with any of the RFLPs.

Adorno, Simone de Beauvoir, Luc Brisson, Christoph Jamme, Geoffrey Stephen Kirk κ.α. Το δεύτερο μέρος εφαρμόζει τις θεωρίες του πρώτου και δείχνει τον ρόλο του αρχαίου μύθου και την αντίθεση με τον λόγο, όπως αυτά παρουσιάζονται στα γερμανόφωνα λογοτεχνικά κείμενα του Max Frisch και της Christa Wolf.
description: The present master’s thesis, with the title “The role of ancient myth in the novels "Homo Faber" by Max Frisch and "Kassandra" by Christa Wolf”, aims towards the search of the ancient myth and its role in both of these novels, whilst focusing on the distinction between myth and logos. In the center of the study are both works’ protagonists and their personal journey from a one-sided logocentric character, to a holistic one. The master’s thesis is structured in two parts: The first part is the theoretical framework, in which I cite, amongst others, theories of Max Horkheimer, Theodor W. Adorno, Simone de Beauvoir, Luc Brisson, Christoph Jamme, Geoffrey Stephen Kirk etc. The second part uses said theories and shows the role of ancient myth and its difference between logos, as they are portrayed in Max Frisch’s and Christa Wolf’s novels.

description: For the funding period 2021-2027, the European Commission wants to redesign the payment scheme in order to achieve a fairer distribution of funds. In this paper we simulate some of the proposed reforms with the agent-based model AgriPoliS. The analysis focuses on the effects of the capping of direct payment and stronger redistributive payment scheme for the first hectares on structural change, farm performance and their implications on land markets. The results show that the Commissions set goals can only be partly achieved by the proposed reform. Our analysis reveal political unintended redistributive effects at the expense of small farms.

description: From 29th - 30th of October, 2009, the 'Data Management Workshop' was held at the University of Cologne, Germany.  This workshop was actively supported by two research projects. The CRC/TR32 'Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling, and Data Assimilation' as well as the CRC 806 'Our way to Europe: Culture-Environment Interaction and Human Mobility in the Later Quaternary', both Collaborative Research Centres of the German Research Foundation (DFG). In addition the workshop was co-organized by the Working Group 5 'Methods for Change Detection and Process Modelling' within the Commission VII 'Thematic Processing, Modelling and Analysis or Remotely Sensed Data' of the International Society for Photogrammetry and Remote Sensing (ISPRS). Since many different scientific communities are facing similar problems in data handling, the aim of the workshop was to bring together a variety of scientific disciplines, which are sometimes recognised as being quite incompatible with one other (e.g. computer sciences, social sciences, geography, physics, pre-history, geoinformatics, archaeology, geosciences, meteorology, and biology). Moreover, the goal was to take into account the perspective of the funding bodies, in our case the DFG.  The workshop was based on 11 invited talks and unusual long coffee breaks, parallel to poster sessions to encourage and support discussion. The diverse program attracted nearly 30 poster presentations and approximately 80 participants. The papers and abstracts of the workshop are summarized in the workshop proceedings.

A numerical study of the partition function and of the vacuum expectation values (VEV) is done by using the truncated conformal space (TCS) approach. Our results strongly suggest that the partition function is an entire function of the coupling constant.

Hints of a Local Matter Underdensity or Modified Gravity in the Low $z$ Pantheon data

description: A redshift tomography of the Pantheon type Ia supernovae (SnIa) data focusing on the best fit value of the absolute magnitude $M$ and/or Hubble constant $H_0$ in the context of $Λ$CDM indicates a local variation ($z\lesssim 0.2$) at $2σ$ level, with respect to the best fit of the full dataset. If this variation is physical, it can be interpreted either as a locally higher value of $H_0$, corresponding to a local matter underdensity $δρ_0/ρ_0 \simeq -0.10 \pm 0.04$ or as a time variation of Newton's constant which implies an evolving Chandrasekhar mass and thus an evolving absolute magnitude $M$ of SnIa. The local void scenario would predict an anisotropy in the best fit value of $H_0$ since it is unlikely that we are located at the center of a local spherical underdensity. Using a hemisphere comparison method we find an anisotropy level consistent with simulated isotropic datasets. We show however, that the anisotropic sky distribution of the Pantheon SnIa data induces a preferred range of directions even in simulated Pantheon data obtained in the context of isotropic $Λ$CDM. We thus construct a more isotropically distributed subset of the Pantheon SnIa and show that the preferred range of directions disappears. Using this subset we again find no evidence for anisotropy using either the hemisphere comparison method or the dipole fit method. In the context of the modified gravity scenario, we allow for an evolving normalized Newton's constant consistent with General Relativity (GR) at early and late times $μ(z)=1+g_a z^2/(1+z)^2-g_a z^4/(1+z)^4$ and fit for $g_a$ assuming $L\sim G_{\rm{eff}}^b$. For $b=-3/2$ indicated by previous studies we find $g_a=-0.47 \pm 0.36$ which is more than $1.5σ$ away from the GR value of $g_a=0$. This weak hint for weaker gravity at low $z$ is consistent with similar evidence from growth and weak lensing data.

description: The agricultural sector of Western Balkan (WB) countries/territories faces major structural and competitiveness issues; in order for the sector to modernize and to approximate to the European Union (EU) standards, they will need to overcome the obstacles in land market. This paper presents the findings of a cross-country analysis of the land market functioning in selected WB countries/territories (Albania, Federation of Bosnia and Herzegovina, Republic of Srpska, Kosovo*1, Republic of North Macedonia, Montenegro and Serbia) with a focus on small farms’ access to land. Analysis is based on data and information collected with the means of survey questionnaire and focus groups with the relevant stakeholders in the countries/territories under review. Results show that the analysed agricultural land markets in WB are generally underdeveloped and that the small farmers have poor access to land and agricultural credits. Among the analysed countries/territories, Serbia has the most developed agricultural land market.

description: The conductance of bulk metal--insulator--metal junctions is evaluated by the Landauer formula using an \textit{ab initio} electronic structure calculated using a plane-waves basis set within density-functional theory (DFT) and beyond, i.e.\ including exact non-local exchange using hybrid functional (HSE) or many-body $G_0W_0$ and COHSEX quasiparticle (QP) schemes. We consider an Ag/MgO/Ag heterostructure model and we focus on the evolution of the zero-bias conductance as a function of the MgO film thickness. Our study shows that the correction of the electronic structure beyond semi-local density functionals goes in the right direction to improve the agreement with experiments, significantly reducing the zero-bias conductance. This effect becomes more evident at larger MgO thickness, that is in increasing tunneling regime. We also observe that the reduction of the conductance seems more related to the correction of wavefunctions rather than energies, and thus not directly related to the correction of the band-gap of bulk MgO. $G_0W_0$ and HSE both provide a correct band-gap in agreement with experiments, but only HSE gives a significant reduction of the conductance. COHSEX, while overestimating the band-gap, gives a reduction of the conductance very close to HSE.

description: Estimates for the asset value of agricultural land come from direct elicitation of farm operators' own assessment of the value of their land. We use data from actual sales transactions to evaluate the extent to which these estimates accurately correspond to the observed market value, or sale price, of land at the county level. We form a short panel at the county-level and compute the difference between the average sales price and the value of land to estimate a county-level fixed effects model. We find that increasing temperatures exacerbates the difference, while increasing population has the opposite relationship.

description: Metal-organic framework materials (MOFs) have been extensively studied as adsorbents for carbon capture applications over past decades. However, when it comes to MOF-based membranes for CO₂ separation, factors that determine membrane performance are not limited to CO₂ adsorption capacity. Especially for mixed matrix membranes, other factors, such as MOF morphology, pore structure, and its compatibility with polymer materials are also of importance and should be considered in membrane design. The relevant background and literature review about the-state-of-the-art technology are provided in Chapter 1. In according to current research, various MOF materials with distinct properties have been applied for membrane-based gas separation in this PhD study, and their performance is discussed in Chapters 4 to 7. In Chapter 4, two types of pure MOF membranes, crystalline and glassy, are introduced, however, they were difficult to work with and their membrane separation performance was not promising. Chapters 5 to 7 discuss the performance of MOFs as fillers in mixed matrix polymer membranes. MOFs were incorporated into two types of polymer at different loadings, namely PEBAX MH1657 and Matrimid®5218. The MOF materials can be classified into three types in terms of their morphology including nanoparticles (Chapter 5), nanoplates (Chapter 6) and nanosheets (Chapter 7). The incorporation of different MOF fillers generally achieved improvements in both gas permeability and some showed improvements in selectivity. A general conclusion is drawn in Chapter 8. In addition, the methodologies of MOF material and membrane preparation as well as material characterisation techniques are introduced in Chapter 3.

description: The emerging topic of sequential recommender systems has attracted increasing attention in recent years.Different from the conventional recommender systems including collaborative filtering and content-based filtering, SRSs try to understand and model the sequential user behaviors, the interactions between users and items, and the evolution of users preferences and item popularity over time. SRSs involve the above aspects for more precise characterization of user contexts, intent and goals, and item consumption trend, leading to more accurate, customized and dynamic recommendations.In this paper, we provide a systematic review on SRSs.We first present the characteristics of SRSs, and then summarize and categorize the key challenges in this research area, followed by the corresponding research progress consisting of the most recent and representative developments on this topic.Finally, we discuss the important research directions in this vibrant area.

Quasiparticle conductance in Spin Valve Josephson Structures

description: We study the quasiparticle current in clean ferromagnetic Josephson structures of the form $S_1/F_1/N/F_2/S_2$, where $S$, $F$, and $N$ denote superconducting, ferromagnetic or normal layers respectively. Our focus is on the structure of the conductance $G$ as a function of bias $V$, emphasizing the subgap region. We use a fully self consistent numerical method, coupled to a transfer matrix procedure to extract $G(V)$. We choose material parameters appropriate to experimentally realized Co Cu Nb structures. We find a resonance peak structure as a function of the intermediate layer thickness and of the misalignement angle $ϕ$ between $F$ layers. To understand this resonance structure, we develop an approximate analytic method. For experimentally relevant thicknesses, the conductance has multiple subgap peaks which oscillate in position between low and critical bias positions. These oscillations occur in both $ϕ$ and the layer thicknesses. We compare our results with those obtained for the spin valve structures $(F_1/N/F_2/S_2)$ and discuss the implications of our results for the fabrication of spin Josephson devices.

description: This article proposes an empirical methodology for accurately estimating the relative permittivity εr of FR4 boards, which is essential for designing microstrip antennas at S and C frequency bands. As the relative permittivity of dielectric materials changes with frequency, the proposed method involves selecting a known starting value of εr for an FR4 board and then simulating the reflection coefficient S11 parameters of an antenna design. These simulated parameters are then compared to the measured S11 parameters of a fabricated antenna. A value of εr = 4.55 is accurately determined when the two S11 parameters converge close to the desired design frequency. With the FR4 εr value obtained from this methodology, a slot patch antenna is designed for a frequency of 4 GHz, obtaining a reflection coefficient of |Γ| = 0.035, a bandwidth BW = 117 MHz, and a standing wave ratio (SWR) of 1.0746. The proposed methodology can be used as a tool to estimate the εr of various substrates that are not characterized at high frequencies.

description: This thesis picks up and attempts to make sense of several of the interrelated major problems and crises that humanity is currently facing, and which reveal where our lifestyles are unsustainable. A more recent of these problems is the societal impact of the software services that large IT companies offer. The dominant business model behind these largely free services comes at the expense of a devastating societal spillover. A second thread are attempts to invent on currencies and their relation to the crises of today’s capitalist system. Here the thesis offers two currency case studies: one by a Surveillance Capitalist and one by a grassroots food movement, a Community Supported Agriculture. The third interwoven thread is the potential of decentralized software architecture, and Blockchain and Blockchain alternatives in particular. This recently growing technology offers a strong narrative to overthrow established centralized monetary and technology institutions. Via a technology assessment and two case studies, this thesis scrutinizes that narrative and comes to disillusioning results.
