description: This study proposes voltage-dependent-synaptic plasticity (VDSP), a novel brain-inspired unsupervised local learning rule for the online implementation of Hebb's plasticity mechanism on neuromorphic hardware. The proposed VDSP learning rule updates the synaptic conductance on the spike of the postsynaptic neuron only, which reduces by a factor of two the number of updates with respect to standard spike-timing-dependent plasticity (STDP). This update is dependent on the membrane potential of the presynaptic neuron, which is readily available as part of neuron implementation and hence does not require additional memory for storage. Moreover, the update is also regularized on synaptic weight and prevents explosion or vanishing of weights on repeated stimulation. Rigorous mathematical analysis is performed to draw an equivalence between VDSP and STDP. To validate the system-level performance of VDSP, we train a single-layer spiking neural network (SNN) for the recognition of handwritten digits. We report 85.01 $ \pm $ 0.76% (Mean $ \pm $ S.D.) accuracy for a network of 100 output neurons on the MNIST dataset. The performance improves when scaling the network size (89.93 $ \pm $ 0.41% for 400 output neurons, 90.56 $ \pm $ 0.27 for 500 neurons), which validates the applicability of the proposed learning rule for spatial pattern recognition tasks. Future work will consider more complicated tasks. Interestingly, the learning rule better adapts than STDP to the frequency of input signal and does not require hand-tuning of hyperparameters

description: The serendipitous detection of stellar occultations by Outer Solar System objects is a powerful method for ascertaining the small end ($r \lesssim 15$ km) of the size distribution of Kuiper Belt Objects and may potentially allow the exploration of objects as far out as the Oort Cloud. The design and implementation of an occultation survey is aided by a detailed understanding of how diffraction and observational parameters affect the detection of occultation events. In this study, stellar occultations are simulated, accounting for diffraction effects, finite source sizes, finite bandwidths, stellar spectra, sampling, and signal-to-noise. Finally, the possibility of detecting small Outer Solar System objects from the Kuiper Belt all the way out to the Oort Cloud is explored for three photometric systems: a proposed space telescope, Whipple (Kaplan et al. 2003), the Taiwanese-American Occultation Survey (Lehner et al. 2006), and the Multi Mirror Telescope (Bianco 2007).

description: We study a phenomenological ansatz for merging next-to-next-to-leading order (NNLO) calculations with Monte Carlo event generators. We reweight them to match bin-integrated NNLO differential distributions. To test this procedure, we study the Higgs boson production cross-section at the LHC, for which a fully differential partonic NNLO calculation is available. We normalize PYTHIA and MC@NLO Monte Carlo events for Higgs production in the gluon fusion channel to reproduce the bin integrated NNLO double differential distribution in the transverse momentum and rapidity of the Higgs boson. These events are used to compute differential distributions for the photons in the pp \to H \to γγdecay channel, and are compared to predictions from fixed-order perturbation theory at NNLO. We find agreement between the reweighted generators and the NNLO result in kinematic regions where we expect a good description using fixed-order perturbation theory. Kinematic boundaries where resummation is required are also modeled correctly using this procedure. We then use these events to compute distributions in the pp \to H \to W^+W^- \to l^+l^- ν\barν channel, for which an accurate description is needed for measurements at the LHC. We find that the final state lepton distributions obtained from PYTHIA are not significantly changed by the reweighting procedure.

description: In this work, the structural, electrical, and optical properties of bilayer SiX (X= N, P, As, and Sb) are studied using density functional theory (DFT). Five different stacking orders are considered for every compound and their structural properties are presented. The band structure of these materials demonstrates that they are indirect semiconductors. The out-of-plane strain has been applied to tune the bandgap and its electrical properties. The bandgap increases with tensile strain, whereas, compressive strain leads to semiconductor-to-metal transition. The sensitivity of the bandgap to the pressure is investigated and bilayer SiSb demonstrates the highest bandgap sensitivity to the pressure. These structures exhibit Mexican hat-like valence band dispersion that can be approved by a singularity in the density of states. The Mexican-hat coefficient can be tuned by out-of-plane strain. Optical absorption of these compounds shows that the second and lower valence bands due to the high density of states display a higher contribution to optical transitions.
Link strength in Bayesian networks
Creators: name: Boerlage, Brent
Publisher: name: University of British Columbia
Year: 2008

description: This thesis introduces the concept of a connection strength (CS) between two nodes of a propositional Bayesian network (BN). Connection strength is a generalization of node independence, from a binary property to a graded measure. The connection strength from node A to node B is a measure of the maximum amount that the belief in B will change when the truth value of A is learned. If the belief in B does not change, they are independent, and if it changes a great deal, they are strongly connected. It also introduces the link strength (LS) between two adjacent nodes, which is an upper bound on that part of the connection strength between them which is due only to the link between them (and not other paths which may connect them). Calculating connection strengths is computationally expensive, while calculating link strengths is not. An algorithm is provided which finds a bound on the connection strength between any two nodes by combining link strengths along the paths connecting them (which is of complexity linear in the number of links). Such an algorithm lends substance to notions of an "effect" flowing along paths, and "effect" being attenuated by "weak" links, which is terminology that has appeared often in the literature, but only as an intuitive idea. An algorithm for faster, approximate BN inference is presented, and connection strengths are used to provide bounds for its error. A system is proposed for BN diagrams to be drawn with strong links represented by heavy lines and weak links by fine lines, as a visualization aid for humans. Another visualization aid which is explored is the iso-CS contour map, in which the amount that one particular node can effect each of the other nodes is shown as contour lines super-imposed on a regular BN diagram. Anon-trivial example BN is presented, some of its connection strengths are calculated, CS contour maps are constructed for it, and it is displayed with link strength indicated by line width.

description: Water solid interfacial reactions are critical to understanding corrosion. More specifically, it is notoriously difficult to determine how water and solid interact beyond the initial chemisorption to induce the surface dissolution. Here, we report atomic-scale mechanisms of the elementary steps during SiC hydrothermal corrosion, from the initial surface attack to surface dissolution. We find that hydrogen scission reactions play a vital role in breaking Si-C bonds, regardless of the surface orientations. Stable silica layer does not form on the surface, but the newly identified chemical reactions on SiC are analogous to those observed during the dissolution of silica. SiC is dissolved directly into the water as soluble silicic acid. The rate of hydrothermal corrosion determined based on the calculated reaction activation energies is consistent with available experimental data. Our work sheds new light on understanding and interpreting the experimental observations and it provides foundation for design of materials that are resistant to corrosion in water.

description: We report the discovery of a galaxy cluster serendipitously detected as an extended X-ray source in an offset observation of the group NGC 5044. The cluster redshift, z=0.281, determined from the optical spectrum of the brightest cluster galaxy, agrees with that inferred from the X-ray spectrum using the Fe K alpha complex of the hot ICM (z=0.27 +/- 0.01). Based on the 50 ks XMM observation, we find that within a radius of 383 kpc the cluster has an unabsorbed X-ray flux, f_X (0.5-2 keV) = 3.34 (+0.08, -0.13) x 10^{-13} erg/cm^2/s, a bolometric X-ray luminosity, L_X = 2.21 (+0.34, -0.19) x 10^{44} erg/s, kT = 3.57 +/- 0.12 keV, and metallicity, 0.60 +/- 0.09 solar. The cluster obeys the scaling relations for L_X and T observed at intermediate redshift. The mass derived from an isothermal NFW model fit is, M_vir = 3.89 +/- 0.35 x 10^{14} solar masses, with a concentration parameter, c = 6.7 +/- 0.4, consistent with the range of values expected in the concordance cosmological model for relaxed clusters. The optical properties suggest this could be a ``fossil cluster''.

description: The thesis aims to record and document the exosting water-driven grinding mills of Macedonia. The research was based on field trips, where mills were documented through designs and photographs. People who worked, owned or used the watemill where interviewed when this was possible. The research outturns were analyzed and further documented on Greek and foreign relevant literature. The research incorporated 279 watermills. Most of them were driven by small water streams and were placed inside the settlements. The basic type of watermill that was recorded in Macedonia was the one-room, ground floor building, roofed with four-aisled tile roof. The watemills of Macedonia were mainly driven by horizontal waterwheels. The dominance of the horizontal for the small, autarchic, rural settlements of Macedonia. It was more easy and cheap to grind with horizontal waterwheels which were cheaper and easier in their installation and conservation and they didn't need any specialized foremen. The millstones recorded in Macedonia were artificial, made in workshops in Thessaloniki. The watermills of Macedonia stopped working during the '50's and where replaced from oil-driven mills and then from roller-mills

The ship model : a new computational model for distriputed systems
Creators: name: Phillips, George William
Publisher: name: University of British Columbia
Year: 2009

description: One of the fundamental goals of a distributed operating is to make a collection of computers connected by a network appear as a unified whole to the users of the system. The system relies heavily on the network to help maintain this illusion. If the network is not fast enough system performance will be noticeably affected and the system will fail to achieve this primary goal. Since the network is used to allow two entities on different machines to communicate with each other, it is possible to reduce the use of the network by allowing entities to migrate between machines. Two entities on the same machine will not require the network for their communication. A distributed system which supports such a mobility mechanism has two primary benefits. First, it can increase the performance and usability of the system since decreased network communication can generally increase performance. The performance gain is most notable over low speed networks where decreased use of the network is vital for the system to perform adequately. Second, it also makes the design of system interfaces simpler by removing features from the design that are necessary only for good remote interaction. This thesis investigates a mechanism that allows distributed programs to reduce their network usage by moving code segments between computers. The general idea of moving code is developed into an abstract model of distributed computation call the Ship Model. The Ship Model has a basic entity called a ship which contains code and data. It uses mobility both as a way of moving code and data between machines and as an inter-ship communication mechanism. In order to test the viability of the model a prototype implementation is constructed. The prototype is written in C and runs under UNIX with the two parts of the system connected either by a high speed ethernet network or a slow speed dialup line. A few example applications are implemented and tested under the prototype. Various measurements show that for many applications the Ship Model can provide increased performance in a high speed network setting as well as over a slow speed line. Various issues regarding the implementation of the Ship Model are also discussed.

description: For a systematic study of charge degrees of freedom in lattices with geometric frustration, we consider spinless fermions on the checkerboard lattice with nearest-neighbor hopping $t$ and nearest-neighbor repulsion $V$ at quarter-filling. An effective Hamiltonian for the limit $|t|\ll V$ is given to lowest non-vanishing order by the ring exchange ($\sim t^{3}/V^{2}$). We show that the system can equivalently be described by hard-core bosons and map the model to a confining U(1) lattice gauge theory.

We give a complete description of the elementary charge transfer processes, i) transfer of Cooper pairs out of the superconductor by Andreev reflection and ii) distribution of the entangled quasiparticles among the ferromagnetic leads, in terms of their statistics. The probabilities that entangled electrons flow into spatially separated leads are completely determined by experimentally measurable conductances and polarizations. Finally, we investigate how currents, noise and cross correlations are affected by transport of entangled electrons.

description: During aqueous corrosion, atoms in the solid react chemically with oxygen, leading either to the formation of an oxide film or to the dissolution of the host material. Commonly, the first step in corrosion involves an oxygen atom from the dissociated water that reacts with the surface atoms and breaks near surface bonds. In contrast, hydrogen on the surface often functions as a passivating species. Here, we discovered that the roles of O and H are reversed in the early corrosion stages on a Si terminated SiC surface. O forms stable species on the surface, and chemical attack occurs by H that breaks the Si-C bonds. This so-called hydrogen scission reaction is enabled by a newly discovered metastable bridging hydroxyl group that can form during water dissociation. The Si atom that is displaced from the surface during water attack subsequently forms H2SiO3, which is a known precursor to the formation of silica and silicic acid. This study suggests that the roles of H and O in oxidation need to be reconsidered.

description: Color is a complex communicative element that helps us understand and evaluate our environment. At the level of artistic creation, this component influences both the formal aspects of the composition and the symbolic weight, directly affecting the construction and transmission of the message that you want to communicate, creating a specific emotional reaction. During the COVID-19 pandemic, people generated countless images transmitting this event's subjective experiences. Using the repository of images created in the Instagram account CAM (The COVID Art Museum), we propose a methodology to understand the use of color and its emotional relationship in this context. The process considers two stages in parallel that are then combined. First, emotions are extracted and classified from the CAM dataset images through a convolutional neural network. Second, we extract the colors and their harmonies through a clustering process. Once both processes are completed, we combine the results generating an expanded discussion on the usage of color, harmonies, and emotion. The results indicate that warm colors are prevalent in the sample, with a preference for analog compositions over complementary ones. The relationship between emotions and these compositions shows a trend in positive emotions, reinforced by the results of the algorithm a priori and the emotional relationship analysis of the attributes of color (hue, chroma, and lighting).

description: Detecting the presence of timing problems in digital circuits is a difficult matter, but one that can be greatly simplified with the aid of effective analysis tools. Such tools have traditionally lacked the ability to detect the presence of race and hazard conditions. In this thesis we present a simulation tool that is able to detect such problems. In addition, the tool provides two mechanisms for doing so. One approach gives the user the capability of explicitly generating all possible states of the circuit in response to an input change. This type of analysis is extremely time consuming but describes all behaviours possible according to the underlying model. The other approach is far more computationally efficient, dealing mainly with computing the final outcome. Alternatively, this second approach enables the user to analyse a circuit using "symbolic data". However, it is somewhat pessimistic, giving rise to "false negative" results at times. Together though, the two approaches form a useful workbench for verification of circuit designs.

description: The current demand for lightweight structures in a wide range of engineering applications leads to using thin-walled composite laminated structures whose behaviour is governed by buckling and postbuckling phenomena. Such a demand is pushing the borders of computational mechanics to enhance methods and algorithms for studying those structures' geometrically nonlinear responses. This work presents some of the authors' developments in analysing lightweight composite laminated structures. The literature survey introduces a family of finite elements known as MISS elements, where MISS stands for mixed isostatic self-equilibrated stresses. The description of those elements, which are derived from the Hellinger-Reissner functional, is followed by a discussion on their advantages concerning displacement-based elements when studying composite laminated thin-walled structures. Subsequently, a framework for the postbuckling analysis of composite structures with the MISS-4C element that uses the Koiter multi-modal approach is presented.

description: Recent experiments on Pr$_{0.89}$LaCe$_{0.11}$CuO$_4$ observe an anisotropic spin-correlation gap and a nonmonotonic superconducting (SC) gap, which we analyze within the framework of a $t-t^{\prime}-t^{\prime\prime}-t^{\prime\prime\prime}-t^{iv}-U$ model with a $d_{x^2-y^2}$ pairing interaction including a third harmonic contribution. By introducing a realistic broadening of the quasiparticle spectrum to reflect small-angle scattering, our computations explain the experimental observations, especially the presence of a maximum in the leading edge gap in the vicinity of the hot-spots. Our analysis suggests that the material behaves like a {\it two-band} superconductor with the d-wave third harmonic acting as the {\it interband pairing gap}, and that the anti-ferromagnetic (AFM) and SC orders co-exist in a uniform phase.

description: Σύμφωνα με την παρούσα έρευνα και την μελέτη της διεθνούς βιβλιογραφίας,μπορούμε να συμπεράνουμε ότι τα αποτελέσματα της ανοσοϊστοχημικής μελέτης, ηοποία πραγματοποιήθηκε, δεν αποδίδουν μεν άμεσα την έκφραση των κυττάρων, πουσυμμετέχουν στην γένεση του αδαμαντινοβλαστώματος και προέρχονται από τηνευρική ακρολοφία, ενέχουν, όμως, την πιθανότητα της έκφρασης συγκεκριμένωννευροεξωδερμικών πρωτεϊνών, οι οποίες παριστούν ένα είδος αρχέγονης μνήμης,που, όπως φαίνεται, το κύτταρο των οδοντογενών ιστών έχει τη ικανότητα νααποκτήσει, κάτω από συγκεκριμένες παθολογικές συνθήκες. Ένα τέτοιο φαινόμενοείναι πιθανόν να προκύψει κατά τη δημιουργία και άλλων οδοντογενών όγκων, όπωςεπίσης και κατά τη φυσιολογική διαφοροποίηση των οδοντικών ιστών, πιθανόν σε μηανιχνεύσιμα επίπεδα. Επιπλέον, η υπερέκφραση των δεικτών αυτών στα αδαμαντινοβλαστώματα, η οποία και τους προσδίδει ένα συγκεκριμένο ανοσοΐστοχημικό προφίλ, πέρα από κοινό σημείο αναφοράς μεταξύ ετερόκλητων ομάδων νεοπλασμάτων (όπως τα αδαμαντινοβλαστώματα, οι όγκοι της οικογένειας του σαρκώματος Ewing, και το αδαμαντίνωμα), αποτελεί και ένα χρήσιμο διαφοροδιαγνωστικό εργαλείο για τους οδοντογενείς όγκους, η διάγνωση των οποίων μπορεί σε αρκετές περιπτώσεις να είναι αρκετά περίπλοκη και δυσχερής
description: Ameloblastoma is a prominent entity in the group of odonotogenic tumors. It is a benign, odontogenic tumor, with a high rate of local reccurence. It is an epithelial neoplasm of unknown origin. Our objective was to study the expression of CD99, synaptophysin, neuron specific enolase and chromogranin A in a series of ameloblastomas. These markers usually characterize neuroendocrine differentiation in neoplasms. For this purpose we applied immunohistochemical methods in paraffin embedded tissues. Results showed that ameloblastoma has a distinct immunohistochemical profile, similar to that of Ewing’s sarcoma/ PNETs family of tumors. Review of the literature revealed that adamantinoma, a rare neoplasm of the long bones, formerly believed to be related with ameloblastoma, also demonstrates a similar profile. These findings are not only useful in differential diagnosis of odontogenic tumors, but may prove helpful in distinguishing the unknown origin and the aggressive behavior of ameloblastoma

description: Η διατριβή βασίζεται στην διαπίστωση ότι οι ελληνικές πόλεις βρίσκονται σε μειονεκτική θέση εντός του διευρωπαϊκού αστικού δικτύoυ σε θέματα ανταγωνισμού, βιωσιμότητας και ανάπτυξης. Ταυτόχρονα, οι ελληνικές πόλεις(ακόμα και οι μεσαίου μεγέθους) έχουν φτάσει σε ένα σημείο κορεσμού και σημαντικής υποβάθμισης του αστικού περιβάλλοντος, όπου όλα τα πολεοδομικά εργαλεία, που μας προσφέρονται από τα υπάρχοντα θεσμικά πλαίσια, απλώς ανακυκλώνουν τα ίδια προβλήματα και οδηγούν στα ίδια αδιέξοδα. Για διάφορους λόγους, ένα από τα εργαλεία αναπλάσεων δεν έλαβε την προσοχή που λογικά θα άξιζε.

description: The thesis is grounded on the findings that greek cities lie in a disadvantageous position within the European urban network, in terms of competition, sustainability and growth. At the same time, Greek cities (even the middle-sized ones) have reached a critical point of significant devalorization of the urban environment, where all available urban planning legislative tools just recycle the same problems and lead to the same dead-ends. For a variety of reasons, one of these tools was never acknowledged. The “Active City Blocks” urban renewal tool and all other similar to it are able to play a leading role in rejuvenating the urban tissue. After a brief and concise presentation of the existing law, social and morphological frameof urban design in the greek cities, the thesis displays a number of indicative urban renewal projects from Greece and Europe, researches the Active City Block tool failing reasons and argues on its actual advantages and disadvantages. Grouping and encoding the urban morphology of the middle-sized greek cities leads to an objective description of both the theoretical proposals for improving the law frame and the cities’ functionality and a proposed procedure-plan for the study and development of urban regeneration projects, within the concept of the city blocks’ backyards merging. A case study in the city of Volos-Greece, helps to argue that the new and improvedActive City Blocks tool and concept can indeed contribute to the efforts for renewing the greek cities urban tissue and upgrading the urban environment

description: We measure the ratio of cross section times branching fraction, $R_p \equiv σ_{χ_{c2}} {\cal B}(χ_{c2} \to J/ψγ)/ σ_{χ_{c1}} {\cal B}(χ_{c1} \to J/ψγ)$, in 1.1 fb$^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s} =$ 1.96 TeV. This measurement covers the kinematic range $p_T(J/ψ)>4.0$ GeV/$c$, $|η(J/ψ)| < 1.0$, and $p_T(γ)>1.0$ GeV/$c$. For events due to prompt processes, we find $R_p = 0.395\pm0.016(stat.)\pm0.015(sys.)$. This result represents a significant improvement in precision over previous measurements of prompt $χ_{c1,2}$ hadroproduction.

description: An algorithm is presented to fit precipitates in atom probe tomographic data sets as equivalent ellipsoids. Unlike previous techniques, which measure only the radius of gyration, these ellipsoids retain the moments of inertia and principle axes of the original precipitate, preserving crystallographic orientational information. The algorithm is applied to study interconnected gamma prime precipitates (L1_2) in the Gamma-matrix (FCC) of a Ni-Al-Cr alloy. The precipitates are found to coagulate along <110>-type directions.

description: We study Markov chains which model genome rearrangements. These models are useful for studying the equilibrium distribution of chromosomal lengths, and are used in methods for estimating genomic distances. The primary Markov chain studied in this paper is the top-swap Markov chain. The top-swap chain is a card-shuffling process with $n$ cards divided over $k$ decks, where the cards are ordered within each deck. A transition consists of choosing a random pair of cards, and if the cards lie in different decks, we cut each deck at the chosen card and exchange the tops of the two decks. We prove precise bounds on the relaxation time (inverse spectral gap) of the top-swap chain. In particular, we prove the relaxation time is $Θ(n+k)$. This resolves an open question of Durrett.

Photoconductivity in AC-driven modulated two dimensional electron gas in a perpendicular magnetic field

description: In this work we study the microwave photoconductivity of a two-dimensional electron system (2DES) in the presence of a magnetic field and a two-dimensional modulation (2D). The model includes the microwave and Landau contributions in a non-perturbative exact way, the periodic potential is treated perturbatively. The Landau-Floquet states provide a convenient base with respect to which the lattice potential becomes time-dependent, inducing transitions between the Landau-Floquet levels. Based on this formalism, we provide a Kubo-like formula that takes into account the oscillatory Floquet structure of the problem. The total longitudinal conductivity and resistivity exhibit strong oscillations, determined by $ε= ω/ ω_c$ with $ω$ the radiation frequency and $ω_c$ the cyclotron frequency. The oscillations follow a pattern with minima centered at $ω/ω_c =j + {1/2} (l-1) + δ$, and maxima centered at $ω/ω_c =j + {1/2} (l-1) - δ$, where $j=1,2,3.......$, $δ\sim 1/5$ is a constant shift and $l$ is the dominant multipole contribution. Negative resistance states (NRS) develop as the electron mobility and the intensity of the microwave power are increased. These NRS appear in a narrow window region of values of the lattice parameter ($a$), around $a \sim l_B$, where $l_B$ is the magnetic length. It is proposed that these phenomena may be observed in artificially fabricated arrays of periodic scatterers at the interface of ultraclean $GaAs/Al_xGa_{1-x} As$ heterostructures.

description: At one time, 3D computer applications were only available on very specialized and very expensive workstations. However, technology on typical desktop computers has improved dramatically over the last decade, and is now capable of 3D graphics. If shrewd choices are made concerning the graphics hardware and software, a reasonably priced desktop computer will allow adequate real-time interaction for many applications. This thesis investigates some of these choices using a generalized program written to serve as an expandable testbed for evaluating some of the factors affecting user interaction in three dimensions. An important set of 3D tasks that occurs in applications such as computer aided design and computer animation is curve or surface design. Not only is the 3D environment an essential issue in efficiently completing these tasks, but so are the properties of the spline formulation and spline interaction technique chosen to represent the curves or surfaces. Previous work has shown that the B-spline formulation is quite effective for the interactive construction of 2D spline curves. A possible drawback in using the B-spline for the more difficult task of 3D curve construction is the fact that its control vertices may lie far away from the curve, making its manipulation unintuitive. A direct manipulation technique, allowing a curve to be manipulated with points that lie on the curve itself, offers an alternative to control vertex manipulation. An experiment was conducted using the testbed to compare the interactive design of 3D curves using control vertex manipulation of B-spline curves and a particular type of direct manipulation of Bspline curves. The results of the experiment revealed that "direct manipulation" was significantly faster than control vertex manipulation, without sacrificing accuracy in the shape of the final 3D curve.
