description: Μέσα από τη συγκεκριμένη έρευνα, έγινε μια προσπάθεια ποιοτικής και ποσοτικής μελέτης της συμβολής του mentoring στην οργανωσιακή συμπεριφορά των επιχειρήσεων πρωτογενή τομέα, εστιάζοντας στην Περιφέρεια Δυτικής Μακεδονίας. Με τη χρήση της Δελφιδικής μεθόδου και με την συμμετοχή 20 ατόμων χωρισμένων σε 2 ομάδες των 10 ατόμων, (10 ειδικοί σε θέματα mentoring και 10 επιχειρήσεις), πραγματοποιήθηκαν 3 γύροι ερωτήσεων (με τη χρήση ερωτηματολογίων, αλλά και προσωπικών συνεντεύξεων) και παρουσιάστηκε ανάλυση SWOT, στην οποία έγιναν γνωστά τα δυνατά σημεία, τα αδύνατα, οι ευκαιρίες αλλά και οι απειλές του αναπτυξιακού αυτού μοντέλου. Το ‘mentoring’ αποδείχθηκε ότι διαθέτει δυνατά σημεία που υπερέχουν έναντι των αδύνατων, καθιστώντας το γερά θεμελιωμένο στο παρόν. Την ίδια στιγμή, παρουσιάζει υπεροχή ευκαιριών έναντι απειλών, καθιστώντας το πολλά υποσχόμενο για το μέλλον. Η παρούσα διατριβή καταλήγει με προτάσεις, τόσο από ειδικούς σε θέματα mentoring, όσο και από τις επιχειρήσεις, οργανωσιακών μέτρων για ορθότερη και αποτελεσματικότερη εφαρμογή του προγράμματος, ενώ ταυτόχρονα οραματίζεται την αφομοίωση ενός τέτοιου εξελισσόμενου αναπτυξιακού μοντέλου, στους επιχειρηματικούς κύκλους, αποδεικνύοντας εκ των προτέρων, πως ‘ήρθε για να μείνει’.

description: Our aim was to determine the initial Li content of two clusters of similar metallicity but very different ages, the old open cluster NGC 2243 and the metal-rich globular cluster NGC 104. We compared the lithium abundances derived for a large sample of stars (from the turn-off to the red giant branch) in each cluster. For NGC 2243 the Li abundances are from the catalogues released by the Gaia-ESO Public Spectroscopic Survey, while for NGC 104 we measured the Li abundance using FLAMES/GIRAFFE spectra, which include archival data and new observations. We took the initial Li of NGC 2243 to be the lithium measured in stars on the hot side of the Li dip. We used the difference between the initial abundances and the post first dredge-up Li values of NGC 2243, and by adding this amount to the post first dredge-up stars of NGC~104 we were able to infer the initial Li of this cluster. Moreover, we compared our observational results to the predictions of theoretical stellar models for the difference between the initial Li abundance and that after the first dredge-up. The initial lithium content of NGC 2243 was found to be A(Li)_i = 2.85dex by taking the average Li abundance measured from the five hottest stars with the highest lithium abundance. This value is 1.69 dex higher than the lithium abundance derived in post first dredge-up stars. By adding this number to the lithium abundance derived in the post first dredge-up stars in NGC~104, we infer a lower limit of its initial lithium content of A(Li)_i= 2.30dex. Stellar models predict similar values. Therefore, our result offers important insights for further theoretical developments.

description: In recent years, thanks to new facilities such as LOFAR capable of sensitive observations, much work has been done on the detection of stellar radio emission at low frequencies. Such emission has commonly been shown to be coherent emission, generally attributed to electron-cyclotron maser emission, and has usually been detected from main-sequence M dwarfs. Here we report the first detection of coherent emission at low frequencies from T Tauri stars, which are known to be associated with high levels of stellar activity. Using LOFAR, we have detected several bright radio bursts at 150 MHz from two weak-line T Tauri stars: KPNO-Tau 14 and LkCa 4. All of the bursts have high brightness temperatures ($10^{13} - 10^{14}\ \mathrm{K}$) and high circular polarization fractions (60 - 90 \%), indicating that they must be due to a coherent emission mechanism. This could be either plasma emission or electron-cyclotron maser (ECM) emission. Due to the exceptionally high brightness temperatures seen in at least one of the bursts ($\geq 10^{14}\ \mathrm{K}$), and the high circular polarization levels, it seems unlikely that plasma emission could be the source and so ECM is favoured as the most likely emission mechanism. Assuming this is the case, the required magnetic field in the emission regions would be 40 - 70 G. We determine that the most likely method of generating ECM emission is plasma co-rotation breakdown in the stellar magnetosphere. There remains the possibility, however, it could be due to an interaction with an orbiting exoplanet.

description: To probe the quenching mechanisms under high current densities, current-voltage curves have been measured in YBa2Cu3O7-delta thin film microbridges with widths lower than the thermal diffusion length. This condition was obtained by using microbridge widths under 100 micrometers and stepped ramps of one millisecond step duration. Whereas the flux-flow resistivity is found to be microbridge-width independent, strong width dependence of the quenching current density is observed. These results provide a direct experimental demonstration that for high current densities varying in the millisecond range the transition to a highly dissipative state is due to self heating driven by "conventional" (non-singular) flux flow effects.

description: The purpose of this dissertation thesis is the detailed presentation of the legal framework, applied in Greece, related to the reuse of public sector information after the adoption of the Directive 2013/37/EE and the enactment of Law 4305/2014. The first part of the study lists some introductory remarks on the opening of public information and its importance. Then, in the second section, which is the main core of this paper, was attempted a thorough study of legislation on the reuse of public information. Specifically, this section researches the constitutional guarantees for the reuse of public sector information, the European open data policy, and finally the institutional framework in Greek legal system through its historical evolution, namely from the early provisions of Law 3448/2006 up to the enactment of Law 4305/2014. The same section highlights the legal establishment of open data by default and makes an attempt to interpret the existing legal provisions. The third and last section evaluates the outcome of the open data applications, and the thesis is completed by some concluding thoughts.

description: Already in the 1960s Grothendieck understood that one could obtain an almost entirely satisfactory theory of motives over a finite field when one assumes the full Tate conjecture. In this note we prove a similar result for motivic complexes. In particular Beilinson's Q-algebra of "correspondences at the generic point" is then defined for all connected varieties. We compute this for all smooth projective varieties (hence also for varieties birational to such a variety).

description: Hardware performance counters (HPCs) that measure low-level architectural and microarchitectural events provide dynamic contextual information about the state of the system. However, HPC measurements are error-prone due to non determinism (e.g., undercounting due to event multiplexing, or OS interrupt-handling behaviors). In this paper, we present BayesPerf, a system for quantifying uncertainty in HPC measurements by using a domain-driven Bayesian model that captures microarchitectural relationships between HPCs to jointly infer their values as probability distributions. We provide the design and implementation of an accelerator that allows for low-latency and low-power inference of the BayesPerf model for x86 and ppc64 CPUs. BayesPerf reduces the average error in HPC measurements from 40.1% to 7.6% when events are being multiplexed. The value of BayesPerf in real-time decision-making is illustrated with a simple example of scheduling of PCIe transfers.

description: Large-scale electrophysiological simulations to obtain electrocardiograms (ECG) carry the potential to produce extensive datasets for training of machine learning classifiers to, e.g., discriminate between different cardiac pathologies. The adoption of simulations for these purposes is limited due to a lack of ready-to-use models covering atrial anatomical variability. We built a bi-atrial statistical shape model (SSM) of the endocardial wall based on 47 segmented human CT and MRI datasets using Gaussian process morphable models. Generalization, specificity, and compactness metrics were evaluated. The SSM was applied to simulate atrial ECGs in 100 random volumetric instances. The first eigenmode of our SSM reflects a change of the total volume of both atria, the second the asymmetry between left vs. right atrial volume, the third a change in the prominence of the atrial appendages. The SSM is capable of generalizing well to unseen geometries and 95% of the total shape variance is covered by its first 23 eigenvectors. The P waves in the 12-lead ECG of 100 random instances showed a duration of 104ms in accordance with large cohort studies. The novel bi-atrial SSM itself as well as 100 exemplary instances with rule-based augmentation of atrial wall thickness, fiber orientation, inter-atrial bridges and tags for anatomical structures have been made publicly available. The novel, openly available bi-atrial SSM can in future be employed to generate large sets of realistic atrial geometries as a basis for in silico big data approaches.

description: It has been suggested that some strongly correlated matter might be understood qualitatively in terms of liquid crystalline phases intervening between the Fermi gas and the Wigner crystal or Mott insulator. We propose a tunable realisation of this soft quantum matter physics in an ultra-cold gas. It uses optical lattices and dipolar interactions to realise a particularly simple model. Our analysis reveals a rich phase diagram featuring a meta-nematic transition where the Fermi liquid changes dimensionality; a smectic phase (stripes); and a crystalline, `checkerboard' phase.

description: In this work we study the complex entanglement between spin interactions, electron correlation and Janh-Teller structural instabilities in the 5d$^1$ $J_{eff}=\frac{3}{2}$ spin-orbit coupled double perovskite $\rm Ba_2NaOsO_6$ using first principles approaches. By combining non-collinear magnetic calculations with multipolar pseudospin Hamiltonian analysis and many-body techniques we elucidate the origin of the observed quadrupolar canted antifferomagnetic. We show that the non-collinear magnetic order originates from Jahn-Teller distortions due to the cooperation of Heisenberg exchange, quadrupolar spin-spin terms and both dipolar and multipolar Dzyaloshinskii-Moriya interactions. We find a strong competition between ferromagnetic and antiferromagnetic canted and collinear quadrupolar magnetic phases: the transition from one magnetic order to another can be controlled by the strength of the electronic correlation ($U$) and by the degree of Jahn-Teller distortions.

description: Consider an inviscid Burgers equation whose initial data is a Levy a-stable process Z with a > 1. We show that when Z has positive jumps, the Hausdorff dimension of the set of Lagrangian regular points associated with the equation is strictly smaller than 1/a, as soon as a is close to 1. This gives a negative answer to a conjecture of Janicki and Woyczynski. Along the way, we contradict a recent conjecture of Z. Shi about the lower tails of integrated stable processes.

description: Local spins coupled to superconductors give rise to several emerging phenomena directly linked to the competition between Cooper pair formation and magnetic exchange. These effects are generally scrutinized using a spectroscopic approach which relies on detecting the in-gap bound modes arising from Cooper pair breaking, the so-called Yu-Shiba-Rusinov (YSR) states. However, the impact of local magnetic impurities on the superconducting order parameter remains largely unexplored. Here, we use scanning Josephson spectroscopy to directly visualize the effect of magnetic perturbations on Cooper pair tunneling between superconducting electrodes at the atomic scale. By increasing the magnetic impurity orbital occupation by adding one electron at a time, we reveal the existence of a direct correlation between Josephson supercurrent suppression and YSR states. Moreover, in the metallic regime, we detect zero bias anomalies which break the existing framework based on competing Kondo and Cooper pair singlet formation mechanisms. Based on first-principle calculations, these results are rationalized in terms of unconventional spin-excitations induced by the finite magnetic anisotropy energy. Our findings have far reaching implications for phenomena that rely on the interplay between quantum spins and superconductivity.
Essays on production and pricing decisions

Publisher: name: University of British Columbia
Year: 2009

description: There has been considerable interest in finding and explaining the basic elements that can drive product quality up. In the literature this is largely done by modelling the effects of investing in learning and process improvement, and of cost reduction. In the first essay, demand is modelled as a function of price and quality. With this demand function, the firm should produce output of higher quality, the increase in quality being dependent on consumers’ sensitivity to quality and to price, and the effect of technological improvement on product price and quality are very different from those when the demand is a function of price alone. Some twenty states in the U.S. have passed recycling laws which mandate consumption of old newspaper by the newsprint industry. To study the effect of regulation, a model is used in which two firms compete under the regulatory constraint—one firm producing the recycled product, the other the virgin product. Assuming the regulatory constraint is binding, and the demand for the recycled product is derived solely from the legislation, interesting results such as the two firms share equal profits, and consumers pay higher average price in competitive equilibrium than the cartel price, are obtained in the second essay. The two firm model is generalized to include n firms which compete under the same kind of regulatory constraint in the third essay. Results similar to the two firm case are obtained. When the recycled product and the virgin product are partially substitutable, regulation that mandates consumption of the recycled product results in infinitely many equilibria. A dominating equilibrium exists if the demand parameters satisfy a certain condition, otherwise it is not clear how to select an equilibrium. On the other hand, a suitable tax on the virgin product, or its producer, serves to induce compliance with the recycling policy and equilibrium selection. The equilibrium prices and profits of the two firms under the schemes of production tax, excessive consumption tax and progressive profit tax are examined and compared in the fourth essay. It is interesting to find that the tax rate for excessive consumption is comparatively low and, in equilibrium, this tax scheme collects no tax payment.

description: Considering a two-component Bose-Einstein condensate in a double-well potential, a method to generate a Bell state consisting of two spatially separated condensates is suggested. For repulsive interactions, the required tunnelling control is achieved numerically by varying the amplitude of a sinusoidal potential difference between the wells. Both numerical and analytical calculations reveal the emergence of a highly entangled mesoscopic state.

description: We investigate nonlinear transmission in a layered structure consisting of a slab of positive index material (PIM) with Kerr-type nonlinearity and a sub-wavelength layer of linear negative index material (NIM) sandwiched between semi-infinite linear dielectrics. We find that a thin layer of NIM leads to significant changes in the hysteresis width when the nonlinear slab is illuminated at an angle near that of total internal reflection. Unidirectional diode-like transmission with enhanced operational range is demonstrated. These results may be useful for NIMs characterization and for designing novel NIMs based devices.

description: Electric dipole moments (EDMs) of elementary particles and atoms probe violations of T and P symmetries and consequently of CP if CPT is an exact symmetry. We point out that EDMs can also serve as sensitive probes of CPT-odd, CP-even interactions, that are not constrained by any other existing experiments. Analyzing models with spontaneously broken Lorentz invariance, we calculate EDMs in terms of the leading CPT-odd operators to show that experimental sensitivity probes the scale of CPT breaking as high as 10^{12}GeV.

description: The production spectrum of high-energy muons as a function of depth in the atmosphere is relevant for understanding properties of event rates in deep detectors. For a given atmospheric profile, cascades of heavy nuclei develop at higher altitude than proton showers, giving rise to larger separation of muons at depth. For a given type of primary cosmic ray, seasonal variations in muon rates reflect the fact that higher temperatures correspond to lower densities and to a relative increase in the ratio of decay to re-interaction of the parent mesons. In this paper, we present a generalization of the Elbert formula that tracks meson decay to muons along the trajectory of the primary cosmic-ray nucleus. The convolution of the production spectrum with a changing atmospheric profile provides the dependence of event rates and sizes of muon bundles on temperature and primary mass. We consider applications to IceCube and also to multiple muon events in the compact underground detectors of MINOS and the NOvA Near Detector.

description: By solving a master equation in the Sierpinski lattice and in a planar random-resistor network, we determine the scaling with size L of the shot noise power P due to elastic scattering in a fractal conductor. We find a power-law scaling P ~ L^(d_f-2-alpha), with an exponent depending on the fractal dimension d_f and the anomalous diffusion exponent alpha. This is the same scaling as the time-averaged current I, which implies that the Fano factor F=P/2eI is scale independent. We obtain a value F=1/3 for anomalous diffusion that is the same as for normal diffusion, even if there is no smallest length scale below which the normal diffusion equation holds. The fact that F remains fixed at 1/3 as one crosses the percolation threshold in a random-resistor network may explain recent measurements of a doping-independent Fano factor in a graphene flake.

description: In this essay we discuss the possibilities and associated challenges concerning beyond the Standard Model searches at FCC-ee, such as rare decays of heavy-flavoured particles and long-lived particles. The Standard Model contains several suppression mechanisms, which cause a given group of processes to happen rarely, resulting in rare decays. The interest in these decays lies in the fact that the physics beyond the Standard Model does not need to be affected by the same suppression mechanism and therefore can naturally manifest in these decays. Their interest is reinforced by the recent report of several measurements of $b$-flavoured rare decays, showing deviations with respect to the Standard Model predictions. We will show how the FCC-ee project has unique capabilities to address these scientific questions and will consider the related detector design challenges to meet. Another group of processes discussed are those that produce new particles with relatively long lifetimes, that travel substantial distances inside the detectors before decaying. Models containing long-lived particles can give answers to many open questions of the Standard Model, such as the nature of dark matter, or the neutrino masses, among others; while providing an interesting experimental complement to mainstream searches. Long-lived particles often display unique experimental signatures, such as displaced tracks and vertices, disappearing tracks, or anomalously charged jets. Due to this, they are affected by very low background levels but in exchange, they often require dedicated reconstruction algorithms and triggers.

description: We present an extended comparison of contextualized language models for Hungarian. We compare huBERT, a Hungarian model against 4 multilingual models including the multilingual BERT model. We evaluate these models through three tasks, morphological probing, POS tagging and NER. We find that huBERT works better than the other models, often by a large margin, particularly near the global optimum (typically at the middle layers). We also find that huBERT tends to generate fewer subwords for one word and that using the last subword for token-level tasks is generally a better choice than using the first one.

Bulk viscosity in kaon condensed matter

description: We investigate the effect of $K^-$ condensed matter on bulk viscosity and r-mode instability in neutron stars. The bulk viscosity coefficient due to the non-leptonic process $n \rightleftharpoons p + K^-$ is studied here. In this connection, equations of state are constructed within the framework of relativistic field theoretical models where nucleon-nucleon and kaon-nucleon interactions are mediated by the exchange of scalar and vector mesons. We find that the bulk viscosity coefficient due to the non-leptonic weak process in the condensate is suppressed by several orders of magnitude. Consequently, kaon bulk viscosity may not damp the r-mode instability in neutron stars.

description: The structures of He and Be even-even isotopes are investigated using an axially symmetric Hartree-Fock approach with a Skyrme-IIIls mean field potential. In these simple HF calculations, He and Be isotopes appear to be prolate in their ground states and Be isotopes have oblate shape isomeric states. It is also shown that there exists a level crossing when the nuclear shape changes from the prolate state to the oblate state. The single neutron levels of Be isotopes exhibit a neutron magic number 6 instead of 8 and show that the level inversion between 1/2- and 1/2+ levels occurs only for a largely deformed isotope. Protons are bound stronger in the isotope with more neutrons while neutron levels are somewhat insensitive to the number of neutrons and thus the nuclear size and also the neutron skin become larger as the neutron number increases. In these simple calculations with Skyrme-IIIls interaction no system with a clear indication of neutron halo was found among He and Be isotopes. Instead of it we have found 8He+2n, 2n+8He+2n, and 16Be+2n like chain structures with clusters of two correlated neutrons. It is also shown that 8He and 14Be in their ground states are below the neutron drip line in which all nucleons are bound with negative energy and that 16Be in its ground state is beyond the neutron drip line with two neutrons in positive energy levels.

description: Magnetic multilayers are promising tuneable systems for hosting magnetic skyrmions at/above room temperature. Revealing their intriguing switching mechanisms and associated inherent electrical responses are prerequisites for developing skyrmionic devices. In this work, we theoretically demonstrate the annihilation of single skyrmions occurring through a multilayer structure, which is mediated by hopping dynamics of topological hedgehog singularities known as Bloch points. The emerging intralayer dynamics of Bloch points are dominated by the Dzyaloshinskii-Moriya interaction, and their propagation can give rise to solenoidal emergent electric fields in the vicinity. Moreover, as the topology of spin textures can dominate their emergent magnetic properties, we show that the Bloch-point hopping through the multilayer will modulate the associated topological Hall response, with the magnitude proportional to the effective topological charge. We also investigate the thermodynamic stability of these states regarding the layer-dependent magnetic properties. This study casts light on the emergent electromagnetic signatures of skyrmion-based spintronics, rooted in magnetic-multilayer systems.

description: Το καπιταλιστικό σύστημα τη δεκαετία 1970-1980 μετασχηματίζεται. Τα χρόνια της μεγάλης ανάπτυξης σταματούν με την πετρελαϊκή κρίση και ο νεοφιλελευθερισμός κάνει την εμφάνισή του. Στο πλαίσιο αυτής της μεταστροφής, δημιουργούνται νέα μοντέλα δανεισμού τόσο προς νοικοκυριά, επιχειρήσεις, οργανισμούς όσο και σε ολόκληρα κράτη. Σταδιακά, οι μικρές και αδύναμες οικονομίες αρχίζουν να διαδραματίζουν σημαντικό ρόλο στο παγκόσμιο χρηματοπιστωτικό σύστημα. Μια τέτοια περίπτωση είναι και η Ισλανδία· στήριξε την ανάπτυξή της στην χρηματιστικοποίηση που επέφερε ο νεοφιλελευθερισμός. Ταυτοχρόνως, η απελευθέρωση του δανεισμού έδωσε το έρεισμα για αύξηση των περιουσιακών στοιχείων χωρίς ωστόσο, το μέγεθος των περιουσιών να ανταποκρίνεται στην κεφαλαιακή δυνατότητα των δανειοληπτών και των δανειζομένων. Αποτέλεσμα ενός τέτοιου μοντέλου δανεισμού ήταν η παγκόσμια οικονομική κρίση του 2008. Η Ισλανδία ήταν το κράτος που δέχτηκε το μεγαλύτερο αναλογικά βάρος, με την κατάρρευση των τριών κορυφαίων τραπεζών της και την κατακόρυφη υποτίμηση του εθνικού της νομίσματος. Ωστόσο, η χώρα αυτή διαμόρφωσε ένα πρότυπο μοντέλο αντίδρασης λόγω του ρόλου που διαδραμάτισε ο ισλανδικός λαός στη λήψη των πολιτικο-οικονομικών αποφάσεων αντιμετώπισης της κρίσης. Στην ισλανδική περίπτωση, η κρίση αποτέλεσε ευκαιρία για ξεκαθάρισμα σχέσεων και συμβάσεων. Το αίσθημα ενοχής καταρρίφθηκε, η ιδεολογία του χρέους κατέρρευσε και ο λαός είναι κύριος του εαυτού του.
description: In the 1970s, the capitalist system was transformed. The years of high growth captured by the oil crisis and neoliberalism makes his appearance. As part of this shift, created new lending models both to households, businesses, organizations and to whole nations. Gradually, small and weak economies begin to play an important role in the global financial system. Such as Iceland; supported its development on the financialization introduced by neoliberalism. The result of such borrowing model was the global economic crisis of 2008. Iceland was the country that suffered the greatest proportional weight, with the collapse of the top three banks and the sharp devaluation of the national currency. However, the country has shaped a standard reaction model view of the role played by the Icelandic people in making political and economic anti-crisis decisions. In the Icelandic case, the crisis was an opportunity for settling relations and contracts. The guilt was shot down, the ideology of debt collapsed and the people are masters of themselves.

description: In quantum physics, the density operator completely describes the state. Instead, in classical physics the mean value of every physical quantity is evaluated by means of a probability distribution. We study the possibility to describe pure quantum states and events with classical probability distributions and conditional probabilities and prove that the distributions can not be quadratic functions of the quantum state. Some examples are considered. Finally, we deal with the exponential complexity problem of quantum physics and introduce the concept of classical dimension for a quantum system.

description: Heisenberg's uncertainty principle is often cited as an example of a "purely quantum" relation with no analogue in the classical limit where $\hbar \to 0$. However, this formulation of the classical limit is problematic for many reasons, one of which is dimensional analysis. Since $\hbar$ is a dimensionful constant, we may always work in natural units in which $\hbar = 1$. Dimensional analysis teaches us that all physical laws can be expressed purely in terms of dimensionless quantities. This indicates that the existence of a dimensionally consistent constraint on $Δx Δp$ requires the existence of a dimensionful parameter with units of action, and that any definition of the classical limit must be formulated in terms of dimensionless quantities (such as quantum numbers). Therefore, bounds on classical uncertainty (formulated in terms of statistical ensembles) can only be written in terms of dimensionful scales of the system under consideration, and can be readily compared to their quantum counterparts after being non-dimensionalized. We compare the uncertainty of certain coupled classical systems and their quantum counterparts (such as harmonic oscillators and particles in a box), and show that they converge in the classical limit. We find that since these systems feature additional dimensionful scales, the uncertainty bounds are dependent on multiple dimensionless parameters, in accordance with dimensional considerations.

description: Motivated by the recent realization of a $^{52}$Cr Bose-Einstein condensate, we consider the phase diagram of a general spin-three condensate as a function of its scattering lengths. We classify each phase according to its ``reciprocal spinor,'' using a method developed in a previous work. We show that such a classification can be naturally extended to describe the vortices for a spinor condensate by using the topological theory of defects. To illustrate, we systematically describe the types of vortex excitations for each phase of the spin-three condensate.
