description: Σκοπός της διατριβής ήταν η διερεύνηση της επίδρασης 6 μηνών συστηματικής άσκησης, κατά την διάρκεια της αιμοκάθαρσης, στην επάρκεια της αιμοκάθαρσης καθώς και στη σύσταση του σώματος ασθενών με Χρόνια Νεφρική Νόσο Τελικού Σταδίου , καθώς και η αιτιολόγηση των μεταβολών. Στη μελέτη συμμετείχαν αιμοκαθαιρόμενοι ασθενείς όπου χωρίστηκαν σε δύο ομάδες, στην ομάδα άσκησης και στην ομάδα ελέγχου, μετά από κλήρωση για 6 μήνες. Εκτιμήσαμε την επάρκεια της αιμοκάθαρσης μελετώντας τις μεταβολές της ουρίας στους δείκτες επάρκειας της κάθαρσης , τη διαφορά της ουρίας πριν και μετά την αιμοκάθαρση και τη σύσταση του σώματος με το μόνιτορ για τη σύσταση του σώματος. Οι ασθενείς ολοκλήρωσαν και το τεστ των έξι λεπτών που είναι δείκτης αερόβιας ικανότητας και αντοχής. Το τεστ έδειξε ότι στο τέλος του παρεμβατικού προγράμματος οι ασθενείς διένυσαν περισσότερα μέτρα. Από τα αποτελέσματα της μελέτης φάνηκε ότι οι δείκτες επάρκειας βελτιώθηκαν σημαντικά σε επίπεδο στατιστικής σημαντικότητας. Επίσης βελτιώθηκε η άλιπη μάζα σώματος και η κυτταρική μάζα σώματος ενώ μειώθηκαν τα λιπίδια και η μάζα λιπιδίων
description: The aim of the present thesis was to investigate the effect of 6 months of systematic exercise, during hemodialysis, on the adequacy of hemodialysis as well as on the body composition of patients with chronic end-stage renal disease, as well as the justification of the changes. The study included hemodialysis patients who were divided into two groups, the exercise group and the control group, after a draw for 6 months. We assessed the adequacy of hemodialysis by studying urea changes in clearance proficiency markers, urea difference before and after hemodialysis, and body composition with the body composition monitor. The patients completed the six-minutes walk test that is an indicator of aerobic fitness and endurance. The test showed that at the end of the intervention program the patients spread more meters. The results of the study showed that the adequacy indicators were significantly improved at the level of statistical significance. Also improved lean tissue mass and cell body mass while lipids and adipose tissue mass decreased

description: In the heavy quark and large Nc limits, ordinary (exotic) heavy baryons can be considered as bound states of heavy mesons (anti-mesons)and chiral solitons. In these limits, the heavy mesons (or anti-mesons) and the chiral solitons are extremely heavy and are presumed to fall to the bottom of the effective potential. Previous studies have approximated the effective potential as harmonic about the minimum. However, when realistic masses for the heavy meson and chiral soliton are considered, longer range parts of the effective potential can become relevant. In this paper, we show that these longer-ranged effects yield effective wave functions which are qualitatively very different from those expected from the combined large Nc and heavy quark limits. These potentials can support bound heavy pentaquarks under some conditions. The consequence of these new energy states and wave functions on the Isgur-Wise function for the semileptonic decay of heavy baryons is also considered.

description: CeCd$_3$As$_3$ is a rare-earth triangular-lattice antiferromagnet with large inter-layer separation. Our field-dependent heat capacity measurements at dilution fridge temperatures allow us to trace the field-evolution of the spin-excitation gaps throughout the antiferromagnetic and paramagnetic regions. The distinct gap evolution places strong constraints on the microscopic pseudo-spin model, which, in return, yields a close {\it quantitative} description of the gap behavior. This analysis provides crucial insights into the nature of the magnetic state of CeCd$_3$As$_3$, with a certainty regarding its stripe order and low-energy model parameters that sets a compelling paradigm for exploring and understanding the rapidly growing family of the rare-earth-based triangular-lattice systems.

description: We consider the Poisson Boolean model of continuum percolation. We show that there is a subcritical phase if and only if $E(R^d)$ is finite, where $R$ denotes the radius of the balls around Poisson points and $d$ denotes the dimension. We also give related results concerning the integrability of the diameter of subcritical clusters.

description: Conventional estimators of the anisotropic power spectrum and two-point correlation function (2PCF) adopt the `Yamamoto approximation', fixing the line-of-sight of a pair of galaxies to that of just one of its members. Whilst this is accurate only to first-order in the characteristic opening angle $θ_\max$, it allows for efficient implementation via Fast Fourier Transforms (FFTs). This work presents practical algorithms for computing the power spectrum and 2PCF multipoles using pairwise lines-of-sight, adopting either the galaxy midpoint or angle bisector definitions. Using newly derived infinite series expansions for spherical harmonics and Legendre polynomials, we construct estimators accurate to arbitrary order in $θ_\max$, though note that the midpoint and bisector formalisms themselves differ at fourth order. Each estimator can be straightforwardly implemented using FFTs, requiring only modest additional computational cost relative to the Yamamoto approximation. We demonstrate the algorithms by applying them to a set of realistic mock galaxy catalogs, and find both procedures produce comparable results for the 2PCF, with a slight preference for the bisector power spectrum algorithm, albeit at the cost of greater memory usage. Such estimators provide a useful method to reduce wide-angle systematics for future surveys.

description: System-provided explanations for recommendations are an important component towards transparent and trustworthy AI. In state-of-the-art research, this is a one-way signal, though, to improve user acceptance. In this paper, we turn the role of explanations around and investigate how they can contribute to enhancing the quality of the generated recommendations themselves. We devise a human-in-the-loop framework, called ELIXIR, where user feedback on explanations is leveraged for pairwise learning of user preferences. ELIXIR leverages feedback on pairs of recommendations and explanations to learn user-specific latent preference vectors, overcoming sparseness by label propagation with item-similarity-based neighborhoods. Our framework is instantiated using generalized graph recommendation via Random Walk with Restart. Insightful experiments with a real user study show significant improvements in movie and book recommendations over item-level feedback.

description: We revisit the problem of deciding whether a finitely generated subgroup H is a free factor of a given free group F. Known algorithms solve this problem in time polynomial in the sum of the lengths of the generators of H and exponential in the rank of F. We show that the latter dependency can be made exponential in the rank difference rank(F) - rank(H), which often makes a significant change.

description: Στην παρούσα διπλωματική εργασία μελετάται το φαινόμενο του πλεονάσματος προσόντων ή αλλιώς over qualification το οποίο αφορά την κατάσταση στην οποία ένα άτομο (εργαζόμενος) έχει περισσότερα προσόντα από αυτά που απαιτούνται στη θέση εργασίας του. Αρχικά γίνεται αναφορά στο θεωρητικό τμήμα του συγκεκριμένου φαινομένου μέσα από την παράθεση ορισμών και παραδειγμάτων. Μέσα από τη μελέτη διαφόρων ερευνών που έχουν διεξαχθεί για το πλεόνασμα προσόντων διαπιστώνουμε ότι υπάρχουν τόσο θετικές όσο και αρνητικές επιπτώσεις όταν αυτό λαμβάνει χώρα. Επιπλέον υπάρχουν παρόμοιες καταστάσεις στις οποίες μπορεί να έρθει αντιμέτωπος ένας εργαζόμενος όπως η υποαπασχόληση στην οποία γίνεται σχετική αναφορά. Στη συνέχεια επισημαίνονται οι λόγοι για τους οποίους οι υπεύθυνοι πρόσληψης ανθρωπίνου δυναμικού μπορούν να επωφεληθούν από την επιλογή overqualified ατόμων. Σε τελικό στάδιο διεξάγεται μία έρευνα σε ένα δείγμα περίπου 200 ατόμων η οποία μας κατευθύνει σε συγκεκριμένα συμπεράσματα. Όπως παρατηρήσαμε το φαινόμενο του πλεονάσματος προσόντων έχει αρνητική σημασία για τα άτομα και μπορεί να συνδέεται με την ψυχική τους υγεία
description: The present diploma thesis deals with the phenomenon of over qualification, which refers to a situation in which a person ( employee ) has more qualifications than those required for his/her job. Initially there is a reference to the literature of this phenomenon through the quote of definitions and examples. Through the study of various surveys which are carried out about over qualification , we understand that both positive and negative impacts exist when it occurs. In addition, there are similar situations in which an employee may be confronted, such as underemployment, to which a reference is made. The reasons why HRM can benefit from choosing overqualified individuals are highlighted subsequently. At the final stage a survey is conducted on a sample of about 200 people that directs us to specific conclusions. As we noticed, the phenomenon of over qualification has a negative relation to individuals and may be related to their mental health

description: Recent advances in objective-based uncertainty quantification (objective-UQ) have shown that such a goal-driven approach for quantifying model uncertainty is extremely useful in real-world problems that aim at achieving specific objectives based on complex uncertain systems. Central to this objective-UQ is the concept of mean objective cost of uncertainty (MOCU), which provides effective means of quantifying the impact of uncertainty on the operational goals at hand. MOCU is especially useful for optimal experimental design (OED) as the potential efficacy of an experimental (or data acquisition) campaign can be quantified by estimating the MOCU that is expected to remain after the campaign. However, MOCU-based OED tends to be computationally expensive, which limits its practical applicability. In this paper, we propose a novel machine learning (ML) scheme that can significantly accelerate MOCU computation and expedite MOCU-based experimental design. The main idea is to use an ML model to efficiently search for the optimal robust operator under model uncertainty, a necessary step for computing MOCU. We apply the proposed ML-based OED acceleration scheme to design experiments aimed at optimally enhancing the control performance of uncertain Kuramoto oscillator models. Our results show that the proposed scheme results in up to 154-fold speed improvement without any degradation of the OED performance.

Locke’s theory of toleration and its critics
Creators: name: Raabe, Peter Bruno
Publisher: name: University of British Columbia
Year: 2009

description: It has been argued that Locke's theory of toleration is not only flawed in some respects, but that it lacks relevance for present day North American society since it addresses only the conditions and concerns of Locke's own civil society and historical period. But a detailed analysis of the arguments in the Letter, along with an examination of the criticisms of his letter levelled at him by his contemporary, Jonas Proast, especially, on the issue of the use of force to promote belief, shows that Locke's theory of toleration is in fact logically sound and quite rigorous. Furthermore, an examination of some of Locke's other writings reveals that Locke has based his theory of toleration on sound political and epistemological foundations. A scrutiny of later criticisms by Joseph Priestley, Susan Mendus, Jeremy Waldron, and John Rawls shows that they also fail to diminish either the force of Locke's arguments or the relevance of his theory of toleration to present day issues surrounding religious freedom. Although Locke's intolerance of atheists is shown to be misplaced, it is argued that his approach to universal religious toleration is not at odds with modern approaches from individual rights. It is also argued that he is not mistaken in his assumption that matters of state can, and must, be separated from matters of religion if the peace and security of a state are to be maintained. Locke's theory of toleration is therefore shown to be neither parochial nor historically bound.

description: Within the framework of this diploma thesis we will present the design and implementation of an educational Augmented Reality application developed for Android software. The application aims to assist students in understanding molecular structures. This object was chosen after finding that while there is plenty of Augmented Reality mobile applications to support the learning of Chemistry, most of them are dedicated to the representation of the Periodic Table elements while there is a lack in applications related to the representation of molecular structures. This deficiency is attempted to be covered by 3D Atoms. For the creation of the educational application, the software development process was followed. The original idea was analyzed as was the user group targeted by the application, and the current situation in this area was examined. According to the results obtained from the analysis phase, the structure of the application was designed and then implemented. Finally, the functionality and usability of the application was tested and the conclusions drawn from all stages of development were analyzed. The thesis is divided into two main axes, one consisting of the theoretical framework and the other dealing with the recording of the development stages of the application.

description: Purpose: This study examines the contribution of number morphology to language comprehension abilities among children with specific language impairment (SLI) and age-matched controls. It addresses the question of whether number agreement facilitates the comprehension accuracy of object-initial declarative sentences. According to the predictions of the structural intervention account for German, number agreement should assist the correct interpretation of object-initial sentences.Method: This study examines German-speaking children with SLI and a control group of age-matched typically developing children on their sentence comprehension skills for auditory presented subject–verb–object and object–verb–subject (OVS) sentences. The sentences were manipulated with respect to the number properties of the noun phrases (e.g., one plural and one singular, or both singular) and the number agreement of the verb.Results: The group of children with SLI demonstrated poorer comprehension accuracy in comparison to controls. Comprehension difficulty was limited to OVS sentences among children with SLI. In addition, children with SLI comprehended OVS sentences in which number agreement (with plural subject and verb inflection) indicated the noncanonical word order more accurately than OVS sentences with two singular noun phrases and therein did not differ from controls. Conclusion: The study suggests that number agreement helps alleviate the difficulty with OVS sentences and enhances comprehension accuracy, despite the finding that children with SLI exhibit lower comprehension accuracy and more heterogeneous interindividual differences, relative to controls.

description: Motivated from the central role of the mean-square displacement and its second time-derivative -- that is the velocity autocorrelation function $\left\langle v(0)v(t)\right\rangle=\frac{1}{2} \frac{\mathrm{d}^{2} \left\langle Δr^{2} (t)\right\rangle}{\mathrm{d}t^{2}} $ in the description of Brownian motion, we revisit the physical meaning of the first time-derivative of the mean-square displacement of Brownian particles. By employing a rheological analogue for Brownian motion, we show that the time-derivative of the mean-square displacement $\frac{\mathrm{d}\left\langle Δr^{2} (t) \right\rangle}{\mathrm{d}t}$ of Brownian microspheres with mass $m$ and radius $R$ immersed in any linear, isotropic viscoelastic material is identical to $\frac{N K_B T}{3 πR}h(t)$, where $h(t)$ is the impulse response function of a rheological network that is a parallel connection of the linear viscoelastic material with an inerter with distributed inertance $m_R=\frac{m}{6 πR}$. The impulse response function $h(t)=\frac{3πR}{N K_B T}\frac{\mathrm{d}\left\langle Δr^{2} (t) \right\rangle}{\mathrm{d}t}$ of the viscoelastic material-inerter parallel connection derived in this paper at the stress-strain level of the rheological analogue is essentially the response function $χ(t)=\frac{h(t)}{6πR}$ of the Brownian particles expressed at the force-displacement level by Nishi \textit{et al.} (2018). By employing the viscoelastic material-inerter rheological analogue we derive the mean-square displacement and its time-derivatives of Brownian particles immersed in a viscoelastic material described with a Maxwell element connected in parallel with a dashpot which captures the high-frequency viscous behavior and we show that for Brownian motion in such fluid-like soft matter the impulse response function, $h(t)$ maintains a finite constant value in the long term.

description: We use the random phase approximation to systematically describe the total muon capture rates on all nuclei where they have been measured. We reproduce the experimental values on these nuclei to better than 15% accuracy using the free nucleon weak form factors and residual interactions with a mild $A$ dependency. The isospin dependence and the effects associated with shell closures are fairly well reproduced as well. However, the calculated rates for the same residual interactions would be significantly lower than the data if the in-medium quenching of the axial-vector coupling constant is employed to other than the true Gamow-Teller amplitudes. Our calculation thus suggests that no quenching is needed in the description of semileptonic weak processes involving higher multipole transitions and momentum transfer $\sim m_μ$, with obvious importance to analogous weak processes.

description: We present a numerical study of the dynamics of magnetized, relativistic, non-self-gravitating, axisymmetric tori orbiting in the background spacetimes of Schwarzschild and Kerr black holes. The initial models have a constant specific angular momentum and are built with a non-zero toroidal magnetic field component, for which equilibrium configurations have recently been obtained. In this work we extend our previous investigations which dealt with purely hydrodynamical thick discs, and study the dynamics of magnetized tori subject to perturbations which, for the values of the magnetic field strength considered here, trigger quasi-periodic oscillations lasting for tens of orbital periods. Overall, we have found that the dynamics of the magnetized tori analyzed is very similar to that found in the corresponding unmagnetized models. The spectral distribution of the eigenfrequencies of oscillation shows the presence of a fundamental p mode and of a series of overtones in a harmonic ratio 2:3:.... These simulations, therefore, extend the validity of the model of Rezzolla et al.(2003a) for explaining the high-frequency QPOs observed in the spectra of LMXBs containing a black-hole candidate also to the case of magnetized discs with purely toroidal magnetic field distribution. If sufficiently compact and massive, these oscillations can also lead to the emission of intense gravitational radiation which is potentially detectable for sources within the Galaxy.

description: We consider a dynamic network of individuals that may hold one of two different opinions in a two-party society. As a dynamical model, agents can endlessly create and delete links to satisfy a preferred degree, and the network is shaped by \emph{homophily}, a form of social interaction. Characterized by the parameter $J \in [-1,1]$, the latter plays a role similar to Ising spins: agents create links to others of the same opinion with probability $(1+J)/2$, and delete them with probability $(1-J)/2$. Using Monte Carlo simulations and mean-field theory, we focus on the network structure in the steady state. We study the effects of $J$ on degree distributions and the fraction of cross-party links. While the extreme cases of homophily or heterophily ($J= \pm 1$) are easily understood to result in complete polarization or anti-polarization, intermediate values of $J$ lead to interesting features of the network. Our model exhibits the intriguing feature of an "overwhelming transition" occurring when communities of different sizes are subject to sufficient heterophily: agents of the minority group are oversubscribed and their average degree greatly exceeds that of the majority group. In addition, we introduce an original measure of polarization which displays distinct advantages over the commonly used average edge homogeneity.

description: We investigate properties of superclusters of galaxies found on the basis of the 2dF Galaxy Redshift Survey, and compare them with properties of superclusters from the Millennium Simulation. We study the dependence of various characteristics of superclusters on their distance from the observer, on their total luminosity, and on their multiplicity. The multiplicity is defined by the number of Density Field (DF) clusters in superclusters. Using the multiplicity we divide superclusters into four richness classes: poor, medium, rich and extremely rich. We show that superclusters are asymmetrical and have multi-branching filamentary structure, with the degree of asymmetry and filamentarity being higher for the more luminous and richer superclusters. The comparison of real superclusters with Millennium superclusters shows that most properties of simulated superclusters agree very well with real data, the main differences being in the luminosity and multiplicity distributions.

description: We examine the effects of spatial inhomogeneities on irrotational anisotropic cosmologies by looking at the average properties of anisotropic pressure-free models. Adopting the Buchert scheme, we recast the averaged scalar equations in Bianchi-type form and close the standard system by introducing a propagation formula for the average shear magnitude. We then investigate the evolution of anisotropic average vacuum models and those filled with pressureless matter. In the latter case we show that the backreaction effects can modify the familiar Kasner-like singularity and potentially remove Mixmaster-type oscillations. The presence of nonzero average shear in our equations also allows us to examine the constraints that a phase of backreaction-driven accelerated expansion might put on the anisotropy of the averaged domain. We close by assessing the status of these and other attempts to define and calculate `average' spacetime behaviour in general relativity.

description: This report will describe how Ganglia is utilised within the Scientific Computing Technology (SCT) group at the eScience department of STFC. ganglia is extensively used to monitor usage of Linux computational clusters, e.g. CPU, memory and network traffic. In addition to the standard metrics monitored by Ganglia,, custom metrics are also stored and visualised. This allows the group to monitor the status of the machine room and LSF job status. This report does not cover details of the technology, and for readers who require this, they are refered to [4,3].

description: We study the effects of partial correlations in kinetic hopping terms of long-range disordered random matrix models on their localization properties. We consider a set of models interpolating between fully-localized Richardson's model and the celebrated Rosenzweig-Porter model (with implemented translation-invariant symmetry). In order to do this, we propose the energy-stratified spectral structure of the hopping term allowing one to decrease the range of correlations gradually. We show both analytically and numerically that any deviation from the completely correlated case leads to the emergent non-ergodic delocalization in the system unlike the predictions of localization of cooperative shielding. In order to describe the models with correlated kinetic terms, we develop the generalization of the Dyson Brownian motion and cavity approaches basing on stochastic matrix process with independent rank-one matrix increments and examine its applicability to the above set of models.

description: We introduce a reducibility on classes of structures, essentially a uniform enumeration reducibility. This reducibility is inspired by the Friedman-Stanley paper on using Borel reductions to compare classes of countable structures. This reducibility is calibrated by comparing several classes of structures. The class of cyclic graphs and the class of finite prime fields are equivalent, and are properly below the class of arbitrary finite graphs. The class of finite graphs and the class of finite linear orders are maximal among all classes of finite structures. We also prove some general characterizations of reducibility to certain classes. Examples of large chains and antichains of classes are constructed.

description: The axial magnetic effect (AME) is one of the anomalous transport phenomena in which the energy current is induced by an axial magnetic field. Here, we numerically study the AME for the relativistic Wilson fermion in the axial magnetic field and a twisted Dirac semimetal. The AME current density inside the bulk is nonzero, and particularly in the low-energy regime for the former model, it is explained by the field-theoretical results without any fitting parameter. However, for both models, the average AME current density vanishes owing to the surface contribution. The axial gauge field is regarded as the spatially modulated (effective) Zeeman field and induces the spatially modulated energy magnetization. The AME is attributed to the magnetization energy current and hence cannot be observed in transport experiments.

description: In this work, we present the analysis of 35,464 M-dwarf stars located within 100 parsecs in the Transiting Exoplanet Survey Satellite (TESS) Full Frame Images (FFIs) of the observed southern ecliptic hemisphere sectors 1 – 5. We present a new pipeline called NEMESIS which was developed to extract photometry, remove instrumental effects and perform transit searches of single sector data in TESS FFIs. As many M-dwarfs are faint and are not observed with a 2 minute cadence by TESS, FFI transit surveys can give an empirical validation of how many planets are missed by using the 30 minute cadence data. In this work, we detected 183 threshold crossing events and present 29 planet candidates for Sectors 1 – 5, 24 of which are new detections. Our sample contains orbital periods ranging from 1.25 – 6.84 days and planetary radii from 1.26 – 5.31 R⊕. We intend to extract light curves of other nearby M-dwarfs in TESS FFIs observed in Sectors 6 – 26 and will provide all of our data products for our planet candidates.

description: We have investigated the dynamics of the electron-nuclei coupled system in quantum dots. The bunching of results of the electron spin measurements and the revival in the conditional probabilities are salient features of the nuclear spin memory. The underlying mechanism is the squeezing of the nuclear spin state and the correlations between the successive electron spin measurements. Further we make a proposal for the preparation and detection of superposition states of nuclear spins merely relying on electron spin measurements. For unpolarized, completely random nuclear spin state one can still trace the quantum interference effects. We discuss the realization of these schemes for electron spins on both single and double QDs.
