description: High density magnetized detectors are well suited to exploit the outstanding purity and intensities of novel neutrino sources like Neutrino Factories and Beta Beams. They can also provide independent measurements of leptonic mixing parameters through the observation of atmospheric muon-neutrinos. In this paper, we discuss the combination of these observables from a multi-kton iron detector and a high energy Beta Beam; in particular, we demonstrate that even with moderate detector granularities the neutrino mass hierarchy can be determined for $θ_{13}$ values greater than 4$^\circ$.

description: Στο πλαίσιο της ανάλυσης της διακινδύνευσης πλημμύρας, και ειδικότερα του προσδιορισμού των πηγών της, είναι αναγκαία η μελέτη και η εκτίμηση των ακραίων γεγονότων που προκαλούν τέτοια φαινόμενα. Αρχικά, στη διατριβή αυτή παρουσιάζεται ένα μοντέλο ανεξάρτητων υπερβάσεων “POT” (Peaks Over Threshold), που χρησιμοποιεί για την περιγραφή τους μια μη-ομοιογενή σημειακή ανέλιξη. Για τον υπολογισμό των παραμέτρων του μοντέλου χρησιμοποιούνται οι μέθοδοι της Μέγιστης Πιθανοφάνειας, του Bayes και των L-Ροπών. Η Θεωρία Ακραίων Τιμών χρησιμοποιείται στη συνέχεια για την ανίχνευση πιθανών έκτοπων τιμών. Στη συνέχεια, εξετάζονται φαινόμενα μη-στασιμότητας, όπως η εποχικότητα και οι μακροχρόνιες τάσεις και η επίδρασή τους στα μοντέλα ακραίων τιμών. Για τον προσδιορισμό της «εποχικής» συνιστώσας του σήματος χρησιμοποιείται ο κυματιδιακός μετασχηματισμός. Για την προσομοίωση των χρονικών τάσεων των δεδομένων ακραίων τιμών, χρησιμοποιούνται απλές παραμετρικές και μη-παραμετρικές μέθοδοι. Στη συνέχεια, πραγματοποιείται ανάλυση των χωρικών ακραίων τιμών της μετεωρολογικής παλίρροιας και διμεταβλητή ανάλυση του κυματικού κλίματος, εξετάζοντας τα ζεύγη ύψος κύματος-μετεωρολογική παλίρροια και ύψος κύματος-περίοδος κύματος
description: In a general flood risk analysis framework, and especially when dealing with the sources of flooding, it is essential to study and estimate the extreme events which are closely related to such phenomena. A “POT” model for threshold exceedances is presented and analyzed. This model uses a non-homogeneous point process to characterize events exceeding appropriately defined thresholds. To calculate the parameters of the extreme value model, different methods of estimation are tried the Maximum Likelihood Estimation procedure, the Bayesian estimation and the method of L-Moments. Extreme Value Theory is also used in the thesis to detect possible outliers in hydraulic and hydrologic series. One of the main subjects of concern of the present thesis is the study of non-stationary phenomena, such as seasonality and long term trends in the time series under consideration, and their effect on extreme value models. To define the seasonal component of a signal, the wavelet transform is utilised. To model the long term temporal trends of extreme datasets, both parametric functions of time and non-parametric methods are used. The univariate analysis is followed by a spatial analysis of the wave climate, examining the bivariate pairs of wave height and surge and also of wave height and concomitant wave period
CNN Architecture Comparison for Radio Galaxy Classification

description: The morphological classification of radio sources is important to gain a full understanding of galaxy evolution processes and their relation with local environmental properties. Furthermore, the complex nature of the problem, its appeal for citizen scientists and the large data rates generated by existing and upcoming radio telescopes combine to make the morphological classification of radio sources an ideal test case for the application of machine learning techniques. One approach that has shown great promise recently is Convolutional Neural Networks (CNNs). Literature, however, lacks two major things when it comes to CNNs and radio galaxy morphological classification. Firstly, a proper analysis of whether overfitting occurs when training CNNs to perform radio galaxy morphological classification using a small curated training set is needed. Secondly, a good comparative study regarding the practical applicability of the CNN architectures in literature is required. Both of these shortcomings are addressed in this paper. Multiple performance metrics are used for the latter comparative study, such as inference time, model complexity, computational complexity and mean per class accuracy. As part of this study we also investigate the effect that receptive field, stride length and coverage has on recognition performance. For the sake of completeness, we also investigate the recognition performance gains that we can obtain by employing classification ensembles. A ranking system based upon recognition and computational performance is proposed. MCRGNet, Radio Galaxy Zoo and ConvXpress (novel classifier) are the architectures that best balance computational requirements with recognition performance.

Weighted SPICE Algorithms for Range-Doppler Imaging Using One-Bit Automotive Radar

description: We consider the problem of range-Doppler imaging using one-bit automotive LFMCW1 or PMCW radar that utilizes one-bit ADC sampling with time-varying thresholds at the receiver. The one-bit sampling technique can significantly reduce the cost as well as the power consumption of automotive radar systems. We formulate the one-bit LFMCW/PMCW radar rangeDoppler imaging problem as one-bit sparse parameter estimation. The recently proposed hyperparameter-free (and hence user friendly) weighted SPICE algorithms, including SPICE, LIKES, SLIM and IAA, achieve excellent parameter estimation performance for data sampled with high precision. However, these algorithms cannot be used directly for one-bit data. In this paper we first present a regularized minimization algorithm, referred to as 1bSLIM, for accurate range-Doppler imaging using onebit radar systems. Then, we describe how to extend the SPICE, LIKES and IAA algorithms to the one-bit data case, and refer to these extensions as 1bSPICE, 1bLIKES and 1bIAA. These onebit hyperparameter-free algorithms are unified within the one-bit weighted SPICE framework. Moreover, efficient implementations of the aforementioned algorithms are investigated that rely heavily on the use of FFTs. Finally, both simulated and experimental examples are provided to demonstrate the effectiveness of the proposed algorithms for range-Doppler imaging using one-bit automotive radar systems.

Are Diffuse High Energy Neutrinos and Gamma-Rays from Starburst Galaxies Observable?

Year: 2006

description: Loeb and Waxman have argued that high energy neutrinos from the decay of pions produced in interactions of cosmic rays with interstellar gas in starburst galaxies would be produced with a large enough flux to be observable. Their model is reexamined here and we obtain an upper limit to the diffuse neutrino flux from starburst galaxies. The upper limit obtained here is a factor of ~5 lower than the flux which they predict. Our predicted neutrino flux would be below the atmospheric neutrino foreground flux at energies below \~300 TeV and therefore would be unobservable. PeV neutrinos from starburst galaxies are also unlikely to be detected. Compared with predicted fluxes from other extragalactic high energy neutrino sources, starburst neutrinos with ~PeV energies would have a flux considerably below that predicted for AGN models. We also estimate an upper limit for the diffuse GeV gamma-ray flux from starburst galaxies to be about two orders of magnitude below the observed gamma-ray background, much less than the background from blazars and more than an order of magnitude below that calculated by Thompson et al.

description: We consider solutions of the KP hierarchy which are elliptic functions of $x=t_1$. It is known that their poles as functions of $t_2$ move as particles of the elliptic Calogero-Moser model. We extend this correspondence to the level of hierarchies and find the Hamiltonian $H_k$ of the elliptic Calogero-Moser model which governs the dynamics of poles with respect to the $k$-th hierarchical time. The Hamiltonians $H_k$ are obtained as coefficients of the expansion of the spectral curve near the marked point in which the Baker-Akhiezer function has essential singularity.

The data were taken during a slow ramping of the COSY internal deuteron beam scattered on a proton target. The excitation function for the reaction d+p->3He+pi0 does not show any structure which could originate from the decay of 3He-eta bound state. We measured also the threshold excitation curve for the d+p->3He+X process, however, contrary to the SATURNE results, we observe no cusp near the eta threshold.

description: An improved method of remote optical absorption spectroscopy and hyperspectral optical absorption imaging is described which takes advantage of the photoacoustic remote sensing detection architecture. A wide range of photoacoustic excitation wavelengths ranging from 210 nm to 1550 nm was provided by a nanosecond tunable source allowing access to various salient endogenous chromophores such as DNA, hemeproteins, and lipids. Sensitivity of the device was demonstrated by characterizing the infrared absorption spectrum of water. Meanwhile, the efficacy of the technique was explored by recovering cell nuclei and oxygen saturation from a live chicken embryo model and by recovering adipocytes from freshly resected murine adipose tissue. This represents a continued investigation into the characteristics of the hyperspectral photoacoustic remote sensing technique which may represent an effective means of non-destructive endogenous contrast characterization and visualization.

Synthetic approach to the agelasimines
Creators: name: Dotse, Anthony Kwabla
Publisher: name: University of British Columbia
Year: 2008

description: Aside from the structural interest and the success achieved in annulation methods as exemplified in schemes 6 and 7 in this laboratory, synthetic work on the agelasimines A and B and their quartenary 9-methyladenine derivative (44) was encouraged by the presence of a variety of biological activities in these natural products. Another aim of this thesis is to confirm the generality of the synthetic method as applied to the total synthesis of ambliol B (48). Copper(I) mediated conjugate addition of allylmagnesium bromide to 3,4-dimethy1-2-cyclohexen-l-one (63), followed by trapping of the enolate generated with trimethylsilyl chloride, produced the silyl enol ether (62), which was converted to the Mannich base (61). Oxidation of this compound with m-CPBA gave an amine-oxide intermediate which eliminated N , N - dimethylhydroxylamine to give the enone (60). Conjugate addition of the novel vinylgermane cuprate (19) to this enone and treatment of resultant ketone (80) with iodine gave the iodide (59). This iodide was employed as the cyclization precursor to the trans-fused substituted bicyclo[4.4.0]decananol (58). Cyclopropanation of the exocyclic double bond in (58) occurred chemoselectively and gave the cyclopropane (67). The remaining double bond was ozonized and the ozonide cleaved to generate an aldehyde which was reduced to the primary alcohol (93). Hydrogenolysis of the cyclopropane ring of this diol provided the diol (55), which is a possible precursor for the synthesis of the agelasimines A (42), B (43) and their quartenary 9-methyladenine derivative (44).

The first two notebooks are in the associated field methods collection (2020-16); the remainder are here (file bundles 010-020). The bulk of the lower-numbered file bundles (003-007, "Mixtec elicitations") are versions of the notes in existence by June 1987 that were reproduced on a typewriter, with handwritten corrections. File bundles 001-009 represent an earlier deposit made by Hinton on behalf of Macaulay.

File bundle Macaulay.002 (typed field notes) was deaccessioned and moved to the field methods collection (2020-16). File bundles containing original notebooks corresponding to fieldwork in Oaxaca in summers 1982 and 1992 (010-020) have relations indicating which sound recordings in collection LA249 they correspond to; file bundles containing the typed notes have relations indicating which original notebook(s) they correspond to. All original notebooks and typed notes have been scanned and are available as digital files here. The PDF files containing the typed notes have been OCR'd and are searchable.

description: A simple analytical model is used to calculate the X-ray heating of the IGM for a range of black hole masses. This process is efficient enough to decouple the spin temperature of the intergalactic medium from the cosmic microwave background (CMB) temperature and produce a differential brightness temperature of the order of $\sim 5-20 \mathrm{mK}$ out to distances as large as a few co-moving Mpc, depending on the redshift, black hole mass and lifetime. We explore the influence of two types of black holes, those with and without ionising UV radiation. The results of the simple analytical model are compared to those of a full spherically symmetric radiative transfer code. Two simple scenarios are proposed for the formation and evolution of black hole mass density in the Universe. The first considers an intermediate mass black hole that form as an end-product of Population III stars, whereas the second considers super-massive black holes that form directly through the collapse of massive halos with low spin parameter. These scenarios are shown not to violate any of the observational constraints, yet produce enough X-ray photons to decouple the spin-temperature from that of the CMB. This is an important issue for future high redshift 21 cm observations.

description: As an important cyber-physical system (CPS), smart grid is highly vulnerable to cyber attacks. Amongst various types of attacks, false data injection attack (FDIA) proves to be one of the top-priority cyber-related issues and has received increasing attention in recent years. However, so far little attention has been paid to privacy preservation issues in the detection of FDIAs in smart grid. Inspired by federated learning, a FDIA detection method based on secure federated deep learning is proposed in this paper by combining Transformer, federated learning and Paillier cryptosystem. The Transformer, as a detector deployed in edge nodes, delves deep into the connection between individual electrical quantities by using its multi-head self-attention mechanism. By using federated learning framework, our approach utilizes the data from all nodes to collaboratively train a detection model while preserving data privacy by keeping the data locally during training. To improve the security of federated learning, a secure federated learning scheme is designed by combing Paillier cryptosystem with federated learning. Through extensive experiments on the IEEE 14-bus and 118-bus test systems, the effectiveness and superiority of the proposed method are verifed.

description: Galaxy interactions are known to trigger starbursts. The young star clusters formed in mergers may be young globular clusters. The ages of these young star clusters yield the timing of interaction-triggered star formation and provide an important way to reconstruct the history of merging galaxies. Here we present the first results from our investigation into age and metallicity of twelve young clusters in the merging galaxy pair NGC 4676, using spectra from the multi-object Low Resolution Imaging Spectrometer (LRIS) on Keck. For ten clusters, comparison of the Balmer emission lines with model equivalent widths (EWs) yields ages less than 10 Myr. Two spectra display Balmer absorption lines typical of star clusters dominated by A-type stars, with estimated ages of about 170 Myr. These ages are comparable to the dynamical age of the tidal tails and are consistent with star formation triggered during the first passage of the pair. The locations of these two clusters in the tidal tails are generally consistent with predictions of shock-induced star formation models. One of these older objects appears unresolved on the image and is luminous enough to qualify as a young globular cluster. Using EWs of the diagnostic lines [OII] and [OIII], we obtain oxygen abundances in the range 7.3 < 12+log(O/H) < 9.0. These values show a nearly flat distribution along the northern tail, suggesting efficient gas mixing in the tail.

description: In few-cycle pulses, the exact value of the carrier-envelope phase difference (CEPD) has a pronounced influence on the ionization dynamics of atoms and molecules. We show that for atoms in circularly polarized light, a change in the CEPD is mapped uniquely to an overall rotation of the system, and results for arbitrary CEPD are obtained by rotation of the results from a single calculation with fixed CEPD. For molecules this is true only for linear molecules aligned parallel with the propagation direction of the field. The effects of CEPD are classified as geometric or non-geometric. The observations are exemplified by strong-field calculations on hydrogen.

description: Recently, real-world recommendation systems need to deal with millions of candidates. It is extremely challenging to conduct sophisticated end-to-end algorithms on the entire corpus due to the tremendous computation costs. Therefore, conventional recommendation systems usually contain two modules. The matching module focuses on the coverage, which aims to efficiently retrieve hundreds of items from large corpora, while the ranking module generates specific ranks for these items. Recommendation diversity is an essential factor that impacts user experience. Most efforts have explored recommendation diversity in ranking, while the matching module should take more responsibility for diversity. In this paper, we propose a novel Heterogeneous graph neural network framework for diversified recommendation (GraphDR) in matching to improve both recommendation accuracy and diversity. Specifically, GraphDR builds a huge heterogeneous preference network to record different types of user preferences, and conduct a field-level heterogeneous graph attention network for node aggregation. We also innovatively conduct a neighbor-similarity based loss to balance both recommendation accuracy and diversity for the diversified matching task. In experiments, we conduct extensive online and offline evaluations on a real-world recommendation system with various accuracy and diversity metrics and achieve significant improvements. We also conduct model analyses and case study for a better understanding of our model. Moreover, GraphDR has been deployed on a well-known recommendation system, which affects millions of users. The source code will be released.

description: We study three structurally different states of nanocrystalline 316 steel and show that the state, where boundaries containing excess concentration of alloying elements are combined with mobile dislocations in grain interiors, allows maintaining extraordinarily high strength and remarkably enhanced plasticity. Underlying mechanisms featuring interaction between the segregations and mobile dislocations are discussed.

description: Traffic congestion is usually observed at the upper streams of bottlenecks such as tunnels. Congestion appears as stop-and-go waves and high density uniform flow. We perform simulations of traffic flow with a bottleneck using the coupled map optimal velocity model. The bottleneck is expressed as a road segment with speed reduction. The speed reduction in the bottleneck controls the emergence of stop-and-go waves. A phenomenological theory of bottleneck effects is constructed.

Extended collinearly-improved Balitsky-Kovchegov evolution equation in target rapidity

description: An extended collinearly-improved Balitsky-Kovchegov evolution equation in the target rapidity representation is derived by including the running coupling corrections during the expansion of the "real" $S$-matrix. We find that the running coupling brings important corrections to the evolution equation, as one can see that there are extra contributions to the evolution kernel once the running coupling is included. To identify the significance of the corrections, we numerically solve the evolution equation with and without the running coupling contributions during the $S$-matrix expansion. The numerical results show that the scattering amplitude is largely suppressed by the running coupling corrections, which indicate that one needs to consider the running coupling contributions during the derivation of the non-linear evolution equation in the target rapidity representation.

description: Στην Ελλάδα έχουν καταγραφεί ελάχιστες προσπάθειες εκπαιδευτικών, οι οποίες να σχετίζονται με την εφαρμογή εκπαιδευτικών παρεμβάσεων προς την κατεύθυνση της κριτικής παιδαγωγικής θεωρίας. Η ανάγκη επιστημονικής έρευνας αυτών των προσπαθειών οδήγησε και στην εκπόνηση της παρούσας διατριβής, της οποίας αντικείμενο είναι οι πρωτοβουλίες που ανέπτυξαν οι εκπαιδευτικοί ενός δημοτικού σχολείου στο κέντρο της Αθήνας με μεγάλο ποσοστό αλλοδαπών μαθητών, με στόχο την ομαλή συνύπαρξη όλων των παιδιών. Η εργασία παρακολουθεί την προσπάθεια του συγκεκριμένου σχολείου για οκτώ συνεχόμενα χρόνια (1999-2007), από την έναρξη των δράσεων που αναπτύχθηκαν στο σχολείο (1999) έως και τη διακοπή τους (2007) μετά από παρέμβαση της διοίκησης. Στη συγκεκριμένη εργασία μελετάται η επίδραση αυτών των δράσεων και τα αποτελέσματά τους για τους Έλληνες και αλλοδαπούς μαθητές, τους γονείς τους αλλά και για τους εκπαιδευτικούς του σχολείου. Εξετάζεται δηλαδή το «πόσο» και το «πώς» αυτές οι δράσεις επηρέασαν τη σχολική κοινότητα και συνακόλουθα τη σχολική αποτελεσματικότητα, έτσι όπως αυτή ορίζεται μέσα από την έννοια του δημοκρατικού και ανθρώπινου σχολείου
description: There have been very few recorded efforts by teachers in Greece, concerning the application of educational interventions on the direction of critical pedagogy. The need for scientific research on these efforts led to the elaboration of the current dissertation, whose subject is the initiatives developed by the teachers of a public primary school in the centre of Athens with a high percentage of immigrant pupils, with the aim being the normal co-existence of all children. The paper follows the efforts of a specific school for eight consequent years (1999 - 2007), from the initial development of practices in the school (1999) until their suspension (2007) after intervention by the administration. The effect of these practices has been investigated in this paper and their outcomes for the Greek and immigrant pupils, for their parents as well as for the teachers of the school. It is investigated therefore, the “how” and “how much” these practices have affected the school community and consequently school efficiency, as the later is defined within the concept of a democratic and humanitarian school

description: We study theoretically the charge polarization and the charge current dynamics of a mesoscopic ring driven by short asymmetric electromagnetic pulses and threaded by an external static magnetic flux. It is shown that the pulse-induced charge polarization and the associated light-emission is controllable by tuning the external magnetic flux. Applying two mutually perpendicular pulses triggers a charge current in the ring. The interplay between this nonequilibrium and the persistent currents is investigated and the conditions under which the pulses stop the persistent current are identified.

description: The unpolarized, helicity and transversity distributions of quarks in the proton are calculated in the overlap representation of light-cone wavefunctions truncated to the lowest order Fock-space components with three valence quarks. The three distributions at the hadronic scale satisfy an interesting relation consistent with the Soffer inequality. Results are derived in a relativistic quark model including radiative corrections up to the next-to-leading order. Predictions for the double transverse-spin asymmetry in Drell-Yan dilepton production initiated by proton-antiproton collisions are presented. Asymmetries of about 20-30% are found in the kinematic conditions of the PAX experiment.

description: We study the Calabi functional on a ruled surface over a genus two curve. For polarisations which do not admit an extremal metric we describe the behaviour of a minimising sequence splitting the manifold into pieces. We also show that the Calabi flow starting from a metric with suitable symmetry gives such a minimising sequence.

description: The interaction between spins in coupled quantum dots is revealed in distinct fine structure patterns in the measured optical spectra of InAs/GaAs double quantum dot molecules containing zero, one, or two excess holes. The fine structure is explained well in terms of a uniquely molecular interplay of spin exchange interactions, Pauli exclusion and orbital tunneling. This knowledge is critical for converting quantum dot molecule tunneling into a means of optically coupling not just orbitals, but spins.

description: We present one inherent shortcoming of the LDA+U method in respect of its self-interaction correction of the LDA. By reexamining the mean-field approximation on the Hubbard energy in the Hartree-Fock form, we have derived a new expression for the ``double-counting'' energy which led to a more reasonable self-interaction correction in an alternative LDA+U scheme. For the bulk Gd metal, the new scheme resulted in electronic properties more consistent with experiments in comparison to the LDA and the existing LDA+U schemes.
