Year: 2022

The overall objective of the proposed research was to develop a new design approach for mine haul road pavements with stabilized layers. To achieve the proposed research, 2D and 3D Finite Element Models (FEM) were first developed and validated. Then, the validated model was used to investigate the effects of stabilization on the strain and deflection of mine haul roads and rural municipal roads. It was found that stabilization reduces the strain and deflection of roads, herein enhancing the performance. Furthermore, the modelling results indicate that stabilization of lower layers was more effective than that of the surface layer in reducing the strain and deflection. After that, a new design approach was developed based on the theories of elasticity and critical strain limit (CSL) to improve the existing CBR design method. The proposed design method was verified through numerical modelling using the validated FEM model. The results have shown that the proposed design method performed better than the existing CBR design method, especially for roads for ultra-large trucks. Also, it was observed that the design thickness could be reduced if the road is stabilized. Lastly, a 3D tire model of off-the-road trucks was established and assembled with the pavement model for the estimation of the rolling resistance. The results from numerical models suggest that the stiffness change due to road stabilization can noticeably reduce the rolling resistance and fuel consumption.

Despite these findings, the current study has its limitations that need continued investigation. Our 2D model observed that a large portion of rolling resistance could be attributed to road roughness, suggesting that the surface roughness should be included in the effects of stabilization on rolling resistance. To further the investigation, experimental work should be carried out to quantify the effects of stabilization on the change in properties of mine haul roads, and incorporated into the numerical models.

description: The rapid growth of Foreign Direct Investment (FDI) is a significant economic phenomenon of this century as various studies conclude that FDI improve the financial status of the host country. However, notable differences in the distribution of these funds, on a global scale, raise questions with regards to the criteria and the environment that would attract such FDIs. This dissertation aims to enhance our understanding by examining the degree to which elements of Southern Europeans economies, affect the inflow of FDIs. More specifically, this dissertation we will focus on the juxtapositions in culture, corruption and trust in public institutions between the home countries and the host countries. The data are analyzed by means of econometric regressions.
description: Η ταχεία εξάπλωση των Άμεσων Ξένων Επενδύσεων (ΑΞΕ) αποτελεί ένα σημαντικό οικονομικό φαινόμενο του αιώνα καθώς πολλές μελέτες καταλήγουν στο συμπέρασμα ότι οι ΑΞΕ βελτιώνουν την οικονομική κατάστασης της χώρας υποδοχής. Η ύπαρξη όμως, μεγάλων διαφορών στην διανομή αυτών των εισροών, σε παγκόσμιο επίπεδο,  δημιουργεί ερωτήματα σχετικά με τους παράγοντες και το περιβάλλουν που καθορίζουν την προσέλκυση ΑΞΕ. Η παρούσα εργασία θα προσπαθήσει να απαντήσει αυτό ακριβώς το θέμα, εξετάζοντας τις χώρες της Νότιας Ευρώπης και το κατά πόσο τα χαρακτηριστικά τους επηρεάζουν την εισροή των ΑΞΕ. Πιο συγκεκριμένα, θα μελετηθούν διαφορές μεταξύ των χωρών που πραγματοποιούν τις ΑΞΕ και των χωρών υποδοχής αναφορικά με την εθνική κουλτούρα, τη διαφθορά και την εμπιστοσύνη στους θεσμούς. Η ανάλυση των δεδομένων θα πραγματοποιηθεί με τη χρήση οικονομετρικών υποδειγμάτων.

description: Enzymes are mainly extracted from the culture broth of microorganisms. Various commercially available enzyme preparations (EPs) are derived from different microorganisms, and the source of the EP should be the same as that mentioned in the manufacture’s information. The development of analytical methods that can determine the origin of the final products is important for ensuring that the EPs are nontoxic, especially when used as food additives. In this study, various EPs were subjected to SDS-PAGE, and the main protein bands were excised. After in-gel digestion, the generated peptides were analysed using MALDI-TOF MS, and protein identification was performed by searching the set of peptide masses against protein databases. In total, 36 EPs including amylase, β-galactosidase, cellulase, hemicellulase and protease were analysed, and the information about the enzyme sources was obtained for 30 EPs. Among these, the biological sources determined for 25 EPs were consistent with the manufacturer’s information; for the remaining five, enzymes produced by closely-related species were shown as matching proteins due to high sequence similarity. Six enzymes derived from four microorganisms could not be identified because their protein sequences were not registered in the database. As these databases are expanded, this approach of using SDS-PAGE and peptide mass fingerprinting (PMF) can determine the biological origin of enzymes rapidly and contribute to ensuring the safety of EPs.

description: We investigate spherically symmetric spacetimes with an anisotropic fluid and discuss the existence and stability of a dividing shell separating expanding and collapsing regions. We resort to a 3+1 splitting and obtain gauge invariant conditions relating intrinsic spacetimes quantities to properties of the matter source. We find that the dividing shell is defined by a generalization of the Tolman-Oppenheimer-Volkoff equilibrium condition. The latter establishes a balance between the pressure gradients, both isotropic and anisotropic, and the strength of the fields induced by the Misner-Sharp mass inside the separating shell and by the pressure fluxes. This defines a local equilibrium condition, but conveys also a non-local character given the definition of the Misner-Sharp mass. By the same token, it is also a generalized thermodynamical equation of state as usually interpreted for the perfect fluid case, which now has the novel feature of involving both the isotropic and the anisotropic stress. We have cast the governing equations in terms of local, gauge invariant quantities which are revealing of the role played by the anisotropic pressures and inhomogeneous electric part of the Weyl tensor. We analyse a particular solution with dust and radiation that provides an illustration of our conditions. In addition, our gauge invariant formalism not only encompasses the cracking process from Herrera and coworkers but also reveals transparently the interplay and importance of the shear and of the anisotropic stresses.

description: We prove that the bounded derived category of the surface S constructed by Barlow admits a length 11 exceptional sequence consisting of (explicit) line bundles. Moreover, we show that in a small neighbourhood of S in the moduli space of determinantal Barlow surfaces, the generic surface has a semiorthogonal decomposition of its derived category into a length 11 exceptional sequence of line bundles and a category with trivial Grothendieck group and Hochschild homology, called a phantom category. This is done using a deformation argument and the fact that the derived endomorphism algebra of the sequence is constant. Applying Kuznetsov's results on heights of exceptional sequences, we also show that the sequence on S itself is not full and its (left or right) orthogonal complement is also a phantom category.

description: We study perfect state transfer of quantum walks on signed graphs. Our aim is to show that negative edges are useful for perfect state transfer. Specific results we prove include: (1) The signed join of a negative 2-clique with any positive (n,3)-regular graph has perfect state transfer even if the unsigned join does not. Curiously, the perfect state transfer time improves as n increases. (2) A signed complete graph has perfect state transfer if its positive subgraph is a regular graph with perfect state transfer and its negative subgraph is periodic. This shows that signing is useful for creating perfect state transfer since no complete graph (except for the 2-clique) has perfect state transfer. (3) The double-cover of a signed graph has perfect state transfer if the positive subgraph has perfect state transfer and the negative subgraph is periodic. Here, signing is useful for constructing unsigned graphs with perfect state transfer. Furthermore, we study perfect state transfer on a family of signed graphs called the exterior powers which is derived from a many-fermion quantum walk on graphs.

description: We analyse the full counting statistics (FCS) of a superconducting junction in non-equilibrium in the limit of small interface transparency. In this limit we treat both supercurrent and multiple Andreev reflections on equal footing and show how to generalise previous results for both phenomena. Furthermore, we also allow for different gaps of both superconductors and investigate the intermediate regime which allows to make contact with previous results on normal-superconductor heterostructures. We also compare our predictions in this regime to experimental data.

description: The latest judgment of the General Court in the Intel case annulled the EU Commission's decision from 2009 imposing a €1.06 billion fine on Intel for abusing its dominant position by offering fidelity rebate schemes (case T‑286/09 Intel v Commission ECLI:EU:T:2022:19). The judgment reaffirms the application of an "effects-based" approach which requires careful economic analysis in order to establish the abusive nature of fidelity rebates. The judgment demonstrates that the presumption that fidelity rebates are restrictions of competition by object can be rebutted by the dominant company. It also clarifies that the as efficient competitor (AEC) test is not an indispensable part of the assessment in examining the foreclosure capability of all rebate systems but can be a relevant factor where the Commission has carried it out as part of its assessment of the anticompetitive effects of the rebate schemes. This Insight seeks to examine how this clarification can be translated into concrete lessons not only for future cases but also for other cases dealing with similar issues (i.e. the Qualcomm and Google Shopping cases) and, in particular, the significance of the AEC test as a specific tool to evaluate the anticompetitive effects of fidelity rebates. The Insight concludes that the recent judgment leaves more questions than answers regarding the application of the AEC test, and that it can be seen as signalling the demise of the application of this test for future cases.

description: We have developed the quasi-classical formalism for a self-induced vortex state in ferromagnetic superconductors. By combining the spatially averaged approximation of the superconductivity with the phenomenological form of the ferromagnetism, we demonstrate the thermodynamic properties of the p-wave triplet equal-spin-pairing state with the spontaneous vortex lattice. The occurrence condition for the self-induced vortex state is discussed within this formalism. The comparison of the calculated quantities with the observed ones indicates that the self-induced vortex state indeed occurs in UCoGe, and its pairing symmetry seems to be the A2-type with a small spin difference in the gap magnitudes. In the vicinity of the ferromagnetic quantum critical point with a large uniform susceptibility, it is possible to exhibit the type-II to the type-I transition in the magnetization process.

description: Although numerous archival XMM-Newton observations existed towards the Small Magellanic Cloud (SMC) before 2009, only a fraction of the whole galaxy was covered. Between May 2009 and March 2010 we carried out an XMM-Newton survey of the SMC, in order to obtain a complete overage of both its bar and wing. Thirty-three observations of 30 different fields with a total exposure of about ne Ms filled the missing parts. We systematically processed all available SMC data from the European Photon Imaging Camera. After rejecting observations with very high background we included 53 archival and the 33 survey observations. We produced images in five different energy bands. We applied astrometric boresight corrections using secure identifications of X-ray sources and combine all the images to produce a mosaic, which covers the main body of the SMC. We present an overview of the XMM-Newton observations, describe their analysis and summarise first results which will be presented in follow-up papers in detail. Here, we mainly focus on extended X-ray sources like supernova remnants (SNRs) and clusters of galaxies which are seen in our X-ray images. The XMM-Newton survey represents the deepest complete survey of the SMC in the 0.15-12.0 keV X-ray band. We propose three new SNRs with low surface brightness of a few 10^-14 erg s^-1 cm^-2 arcmin^-2 and large extent. Also several known remnants appear larger than previously measured from X-rays or other wavelengths extending the size distribution of SMC SNRs to larger values.

description: We use the GAMA I dataset combined with GALEX, SDSS and UKIDSS imaging to construct the low-redshift (z<0.1) galaxy luminosity functions in FUV, NUV, ugriz, and YJHK bands from within a single well constrained volume of 3.4 x 10^5 (Mpc/h)^{3}. The derived luminosity distributions are normalised to the SDSS DR7 main survey to reduce the estimated cosmic variance to the 5 per cent level. The data are used to construct the cosmic spectral energy distribution (CSED) from 0.1 to 2.1 \mum free from any wavelength dependent cosmic variance for both the elliptical and non-elliptical populations. The two populations exhibit dramatically different CSEDs as expected for a predominantly old and young population respectively. Using the Driver et al. (2008) prescription for the azimuthally averaged photon escape fraction, the non-ellipticals are corrected for the impact of dust attenuation and the combined CSED constructed. The final results show that the Universe is currently generating (1.8 +/- 0.3) x 10^{35} h W Mpc^{-3} of which (1.2 +/- 0.1) x 10^{35} h W Mpc^{-3} is directly released into the inter-galactic medium and (0.6 +/- 0.1) x 10^{35} h W Mpc^{-3} is reprocessed and reradiated by dust in the far-IR. Using the GAMA data and our dust model we predict the mid and far-IR emission which agrees remarkably well with available data. We therefore provide a robust description of the pre- and post dust attenuated energy output of the nearby Universe from 0.1micron to 0.6mm. The largest uncertainty in this measurement lies in the mid and far-IR bands stemming from the dust attenuation correction and its currently poorly constrained dependence on environment, stellar mass, and morphology.

description: ΣΚΟΠΟΣ: Στόχος της εργασίας αυτής είναι η ανάδειξη και κατανόηση των βασικών τεχνικών σφαλμάτων που μπορούν να εμφανιστούν στις τομογραφίες κωνικής δέσμης (Cone Beam Computed Tomography - CBCT) στη γναθοπροσωπική απεικόνιση, ο προσδιορισμός των αιτιών εμφάνισης τους καθώς και οι τρόποι μείωσης της εμφάνισης τους. Επίσης μελετάται η επίδραση των παραγόντων έκθεσης, του μεγέθους του πεδίου ακτινοβόλησης καθώς και η παρουσία μεταλλικών στην υπό μελέτη περιοχή στην ποιότητα εικόνας των τομογραφικών δεδομένων. ΥΛΙΚΟ-ΜΕΘΟΔΟΣ: Το θεωρητικό μέρος της εργασίας βασίζεται σε βιβλιογραφικές αναφορές καθώς και σε επιστημονικές εργασίες. Για το πειραματικό κομμάτι, λήφθησαν τομογραφικά δεδομένα ενός ομοιώματος ελέγχου ποιότητας για γναθοπροσωπική CBCT (Pro-dent CT MINI) σε δύο CBCT απεικονιστικά συστήματα, το Newtom VGi EVO που παράγει αποκλειστικά τρισδιάστατη απεικόνιση και το υβριδικό Sirona Orthophos Dentsply, για διαφορετικά πεδία απεικόνισης και διαφορετικούς παράγοντες έκθεσης. Στο Sirona Orthophos Dentsply έγινε επίσης λήψη με τη παρουσία μεταλλικού αντικειμένου στο πεδίο απεικόνισης για την προσομοίωση σφαλμάτων που οφείλονται σε μεταλλικά εμφυτεύματα. Η επεξεργασία των τομογραφικών δεδομένων πραγματοποιήθηκε με τη βοήθεια των dicom viewers NNTTM, Xelis και MicroDicom. ΑΠΟΤΕΛΕΣΜΑΤΑ: Από την έρευνα που έγινε διαπιστώθηκε ότι οι αποκτηθείσες εικόνες και από τα δύο απεικονιστικά συστήματα ήταν πιο ομοιογενείς στο κέντρο συγκριτικά με την περιφέρεια. Όσον αφορά τη διακριτική ικανότητα υψηλής αντίθεσης διαπιστώθηκε ότι εξαρτάται αναλογικά από τους παράγοντες έκθεσης ενώ η διακριτική ικανότητα χαμηλής αντίθεσης υπολογίστηκε στα 3mm για το Newtom VGi EVO ενώ στο Sirona Orthophos Dentsply ήταν τόσο χαμηλή που ήταν ανέφικτο να προσδιοριστεί. Στο Newtom VGi EVO παρατηρήθηκε γραμμικότητα στις τιμές των HU ενώ στο Sirona Orthophos Dentsply οι τιμές τείνουν προς τη γραμμικότητα. Στο πείραμα με τον μεταλλικό συνδετήρα ως προς την ομοιογένεια παρατηρήθηκε παρουσία περισσότερου θορύβου στην εικόνα με τον συνδετήρα, ενώ για τη διακριτική ικανότητα υψηλής αντίθεσης, τη διακριτική ικανότητα χαμηλής αντίθεσης και τη γραμμικότητα των HU δεν παρατηρήθηκε κάποια επίδραση από την ύπαρξη του μεταλλικού συνδετήρα. Σε όλες τις εικόνες είναι εμφανές το τεχνικό σφάλμα που οφείλεται στην ύπαρξη του μεταλλικού συνδετήρα. ΣΥΜΠΕΡΑΣΜΑΤΑ: Η επιλογή των παραγόντων έκθεσης καθώς και η παρουσία μεταλλικών αντικειμένων εντός του πεδίου ακτινοβόλησης επηρεάζουν σημαντικά την ποιότητα των παραγόμενων εικόνων στη CBCT της γναθοπροσωπικής χώρας.

description: Η μαστογραφία είναι μία από τις διαχρονικά πολυτιμότερες εξετάσεις και αξίζει την διαρκή της προώθηση στην καθημερινή πρακτική πρόληψης της υγείας. Αυτό οφείλεται στη σημαντική κλινική αξία της μαστογραφίας στη διάγνωση και τον εντοπισμό του καρκίνου του μαστού. Οι σύγχρονες εξελίξεις στην μαστογραφική απεικόνιση έχουν αλλάξει τον τρόπο εργασίας των ακτινολόγων και των ογκολόγων, καθώς και τη ζωή των γυναικών που έχουν αυξημένο κίνδυνο για εμφάνιση του καρκίνου του μαστού. Η μαστογραφία με τη χρήση σκιαγραφικού αποτελεί μια πρόσφατη εξέλιξη της συμβατικής μαστογραφίας. Πρόκειται για μια αναδυόμενη τεχνική μαστογραφίας διπλής ενέργειας με την οποία επιτυγχάνεται βελτιωμένη αντίθεση. Η εκτέλεση της μαστογραφίας με χρήση σκιαγραφικού προϋποθέτει ενδοφλέβια έγχυση ιωδιούχου σκιαγραφικού και κατάλληλο ανασυνδυασμό των εικόνων χαμηλής και υψηλής ενέργειας. Η μαστογραφία με χρήση σκιαγραφικού βοηθά στη βελτίωση της διαγνωστικής ακρίβειας όταν η συνήθης απεικόνιση μαστού παράγει διφορούμενα αποτελέσματα, ενώ μπορεί να εφαρμοστεί αποτελεσματικά και για την αξιολόγηση της έκτασης του καρκίνου σε γυναίκες με πρόσφατα διαγνωσμένο καρκίνο του μαστού και για την παρακολούθηση της ανταπόκρισης στη επικουρική χημειοθεραπεία πριν από τη χειρουργική μαστεκτομή. Σκοπός της παρακάτω εργασίας είναι η αναλυτική περιγραφή της μαστογραφίας με χρήση σκιαγραφικού, από τις τεχνικές λεπτομέρειες που στοιχειοθετούν την ορθή εφαρμογή της από τους ακτινολόγους, μέχρι τους περιορισμούς που ενδεχομένως να την χαρακτηρίζουν στα κλινικά περιβάλλοντα και τις μελλοντικές προοπτικές της χρήσης της. Η μεθοδολογία εκπόνησης της παρακάτω βιβλιογραφικής ανασκόπησης περιλάμβανε την ανεύρεση των πλέον σχετικών με τη μαστογραφία με χρήση σκιαγραφικού δημοσιεύσεων της τελευταίας δεκαετίας, την κριτική τους ανάγνωση και την παράθεση των βασικότερων σημείων τους μετά τη διασταύρωσή τους με άλλες ομόλογες πηγές. Όπως προκύπτει, η μαστογραφία με χρήση σκιαγραφικού παρουσιάζει πολλά πλεονεκτήματα, μεταξύ των οποίων η αυξημένη ανεκτικότητα από τους ασθενείς (σε σύγκριση με την μαγνητική τομογραφία και την μαγνητική τομογραφία με χορήγηση σκιαγραφικού), η προσβασιμότητα, ο σύντομος χρόνος εξέτασης, η ευκολία του ασθενούς και το προσιτό κόστος. Από την άλλη μεριά, στους πρακτικούς περιορισμούς της τεχνικής μπορεί να συμπεριληφθούν οι ανεπιθύμητες ενέργειες από την χορήγηση του σκιαγραφικού, η υψηλή δόση ιονίζουσας ακτινοβολίας, ο ανατομικός θόρυβος, οι ψευδενδείξεις και ο αυξημένος αριθμός των ψευδώς θετικών αποτελεσμάτων που παρουσιάζει. Μερικές από τις μελλοντικές προοπτικές ανάπτυξης των συστημάτων μαστογραφίας με χρήση σκιαγραφικού σχετίζονται με τη βελτίωση των τεχνικών της παραμέτρων, των υπολογιστικών συστημάτων που τη συνοδεύουν και του συνδυασμού της με άλλες τεχνολογίες όπως η οπτική απεικόνιση.

description: We argue using simple models that all successful practical uses of probabilities originate in quantum fluctuations in the microscopic physical world around us, often propagated to macroscopic scales. Thus we claim there is no physically verified fully classical theory of probability. We comment on the general implications of this view, and specifically question the application of classical probability theory to cosmology in cases where key questions are known to have no quantum answer. We argue that the ideas developed here may offer a way out of the notorious measure problems of eternal inflation.

description: We investigate mixing effects on the glass state of binary colloidal hard-sphere-like mixtures with large size asymmetry, at a constant volume fraction phi = 0.61. The structure, dynamics and viscoelastic response as a function of mixing ratio reflect a transition between caging by one or the other component. The strongest effect of mixing is observed in systems dominated by caging of the large component. The possibility to pack a large number of small spheres in the free volume left by the large ones induces a pronounced deformation of the cage of the large spheres, which become increasingly delocalised. This results in faster dynamics and a strong reduction of the elastic modulus. When the relative volume fraction of small spheres exceeds that of large spheres, the small particles start to form their own cages, slowing down the dynamics and increasing the elastic modulus of the system. The large spheres become the minority and act as an impurity in the ordering beyond the first neighbour shell, i.e. the cage, and do not directly affect the particle organisation on the cage level. In such a system, when shear at constant rate is applied, melting of the glass is observed due to facilitated out-of-cage diffusion which is associated with structural anisotropy induced by shear.

description: We complete the formulation of the standard model of first star formation by exploring the possible impact of LiH cooling, which has been neglected in previous simulations of non-linear collapse. Specifically, we find that at redshift z [greater than or equivalent to] 5, the cooling by LiH has no effect on the thermal evolution of shocked primordial gas, and of collapsing primordial gas into minihalos or relic H II regions, even if the primordial lithium abundance were enhanced by one order of magnitude. Adding the most important lithium species to a minimum network of primordial chemistry, we demonstrate that insufficient LiH is produced in all cases considered, about (LiH/Li) [approximately equal] 10⁻⁹ for T [less than or equivalent to] 100 K. Indeed, LiH cooling would only be marginally significant in shocked primordial gas for the highly unlikely case that the LiH abundance were increased by nine orders of magnitude, implying that all lithium would have to be converted into LiH. In this study, photo-destruction processes are not considered, and the collisional disassociation rate of LiH is possibly underestimated, rendering our results an extreme upper limit. Therefore, the cooling by LiH can safely be neglected for the thermal evolution of Population III star-forming gas.

description: Multiple testing on dependent count data faces two basic modelling elements: the choice of distributions under the null and the non-null states and the modelling of the dependence structure across observations. A Bayesian hidden Markov model is constructed for Poisson count data to handle these two issues. The proposed Bayesian method is based on the posterior probability of the null state and exhibits the property of an optimal test procedure, which has the lowest false-negative rate with the false discovery rate under control. Furthermore, the model has either single or mixture of Poisson distributions used under the non-null state. Model selection methods are employed here to decide the number of components in the mixture. Different approaches of calculating marginal likelihood are discussed. Extensive simulation studies and a case study are employed to examine and compare a collection of commonly used testing procedures and model selection criteria.

description: Abridged. Low-metallicity star-forming dwarf galaxies are prime targets to understand the chemical enrichment of the interstellar medium. The HI region provides important constraints on the dispersal and mixing of heavy elements released by successive star-formation episodes. Our primary objective is to study the enrichment of the HI region and the interplay between star-formation history and metallicity evolution. We observed the most metal-poor star-forming galaxy in the Local Universe, I Zw 18, with Hubble/COS. The abundances in the neutral gas are derived from far-UV absorption-lines (HI, CII, CII*, NI, OI, ...) and are compared to the abundances in the HII region. Models are constructed to calculate the ionization structure and the thermal processes. We investigate the gas cooling in the HI region through physical diagnostics drawn from the fine-structure level of C+. We find that HI region abundances are lower by a factor of ~2 as compared to the HII region. There is no differential depletion on dust between the HI and HII region. Using sulfur as a metallicity tracer, we calculate a metallicity of 1/46 solar (vs. 1/31 in the HII region). From the study of abundance ratios, we propose that C, N, O, and Fe are mainly produced in massive stars. We argue that the HI envelope may contain pockets of pristine gas with a metallicity essentially null. Finally, we derive the physical conditions in the HI region by investigating the CII* absorption line. The cooling rate derived from CII* is consistent with collisions with H atoms in the diffuse neutral gas. We calculate the star-formation rate from the CII* cooling rate assuming that photoelectric effect on dust is the dominant gas heating mechanism. Our determination is in good agreement with the values in the literature if we assume a low dust-to-gas ratio (~2000 times lower than the Milky Way value).
