description: The first paper considers a two-stage duopoly model of costless advertising: in the first stage each firm simultaneously chooses the accuracy of signals informing consumers about how much they value its product; in the second stage firms compete in prices. We find that when the distributions of consumers' valuations for each product are identical, independent and symmetric, and the market is covered for any combination of first-stage choices, the subgame-perfect equilibrium involves both firms perfectly informing consumers in order to increase ex post differentiation and reduce price competition. When the market is not covered for all first-stage choices, one firm may no longer choose perfectly accurate signals in equilibrium, as an increase in the informativeness of a signal further lowers the ex post valuation of those consumers indifferent between purchasing or not, causing them to drop out of the market. Numerical results indicate that if the symmetric distribution of valuations is sufficiently peaked, then both firms inform perfectly; otherwise one firm informs perfectly and the other chooses the highest level of informativeness such that the market is covered. The second paper analyses the choice of commodity tax base when countries set their taxes non-cooperatively in a two-country symmetric reciprocal dumping model of homogeneous goods trade with trade costs and horizontal FDI. We show that under our assumption of linear demand, the consumption base (destination principle) weakly dominates the production base (origin principle) for a large range of plant fixed costs. When integration is complete, the destination principle dominates the origin principle for all levels of plant fixed costs below which FDI occurs under the origin principle. The third paper considers a static Cournot duopoly game with incomplete information regarding firms' marginal costs. Each player knows her own unit cost (low or high), but is uncertain of her opponent's cost. Posterior beliefs are consistent if they admit a common prior. Action symmetry holds if total output does not depend on which player has low or high cost. A player has independent beliefs if her posteriors are the same regardless of her type. Beliefs are essentially the same if each player of each type has the same posteriors about the type of the other player, or if they would be the same after a relabelling of types with low switched with high. We prove that action symmetry and consistent beliefs hold simultaneously if and only if beliefs are essentially the same or both players have independent beliefs. A player has independent beliefs and beliefs are consistent if and only if her opponent has independent beliefs and actions are symmetric. Finally, we investigate the degree to which small departures from each of these properties affects these results.

description: The dynamical dielectric function of two dimensional graphene at arbitrary wave vector $q$ and frequency $ω$, $ε(q,ω)$, is calculated in the self-consistent field approximation. The results are used to find the dispersion of the plasmon mode and the electrostatic screening of the Coulomb interaction in 2D graphene layer within the random phase approximation. At long wavelengths ($q\to 0$) the plasmon dispersion shows the local classical behavior $ω_{cl} = ω_0 \sqrt{q}$, but the density dependence of the plasma frequency ($ω_0 \propto n^{1/4}$) is different from the usual 2D electron system ($ω_0 \propto n^{1/2}$). The wave vector dependent plasmon dispersion and the static screening function show very different behavior than the usual 2D case.

description: SrRuO3 (SRO) is an itinerant ferromagnet with strong coupling between the charge, spin, and lattice degrees of freedom. This strong coupling suggests that the electronic and magnetic behaviors of SRO are highly susceptible to changes in the lattice distortion. Here we show how the spin interaction and resultant magnon formation change with the modification in the crystallographic orientation. We fabricated SRO epitaxial thin films with (100), (110), and (111) surface orientations, to systematically modulate the spin interaction and spin dimensionality. The reduced spin dimensionality and enhanced exchange interaction in the (111)-oriented SRO thin film significantly suppresses magnon formation. Our study comprehensively demonstrates the facile tunability of magnon formation and spin interaction in correlated oxide thin films.

description: Ο ζυμομύκητας C. dubliniensis έχει συσχετιστεί με τη μυκητιασική νόσο σε ασθενείς που έχουν προσβληθεί από σακχαρώδη διαβήτη ή λοίμωξη με τον ιό της ανοσολογικής ανεπάρκειας (HIV), καθώς και σε ασθενείς που βρίσκονται σε ανοσοκαταστολή, π.χ. καρκινοπαθείς υπό κυτταροτοξική χημειοθεραπεία ή άτομα μετά από μεταμόσχευση μυελού των οστών. Η συχνότητα των σοβαρών λοιμώξεων που οφείλονται στον C. dubliniensis, καθώς επίσης και η αντίσταση που παρουσιάζει αυτός ο μύκητας στην φλουκοναζόλη και στην αμφοτερικίνη Β, επιβάλλουν την ταυτοποίηση του παθογόνου αυτού ζυμομύκητα. Λόγω του υψηλού βαθμού φαινοτυπικής ομοιότητας που παρουσιάζει με τον C. albicans, η ανίχνευση του C. dubliniensis σε καλλιέργεια κλινικών δειγμάτων, απαιτεί ιδιαίτερες μεθόδους απομόνωσης και ταυτοποίησης, που είναι χρονοβόρες και αυξάνουν σημαντικά το κόστος της διαδικασίας. Στην εργασία αυτή μελετήθηκαν διάφορα φαινοτυπικά χαρακτηριστικά με σκοπό την ταυτοποίηση ζυμομυκήτων σε πρώτη καλλιέργεια κλινικών δειγμάτων. Ιδιαίτερα, μελετήθηκε η μορφολογία των αποικιών σε άγαρ εκχυλίσματος καπνού (Tobacco Agar) και η επίδραση της θερμοκρασίας, του pH, της γλυκόζης και της πεπτόνης στην μορφολογία τους. Βρέθηκε ότι ο C. dubliniensis σχηματίζει αποικίες με ανώμαλη επιφάνεια και υφές, ενώ οι αποικίες του C. albicans έχουν λεία επιφάνεια χωρίς υφές. Ο σχηματισμός των υφών εξαρτάται από τη θερμοκρασία και το χρόνο επώασης. Άλλοι παράγοντες που μπορούν να επηρεάσουν σε ποικίλο βαθμό τον σχηματισμό υφών είναι η προσθήκη πεπτόνης και γλυκόζης καθώς και το pH του Tobacco Agar. Εκτός του C. dubliniensis υφές μπορούν να σχηματίσουν στο Tobacco Agar οι ζυμομύκητες C. tropicalis, C. krusei, C. parapsilosis και C. lusitaniae.

description: In this study, novel use of the electromagnetic field profile of a localized spoof surface plasmonic mode to detect electron spin resonance is being reported. The mode is supported on a resonator with a complementary metallic spiral structure, etched on the ground plane of a microstrip line having a characteristic impedance of 50 $Ω$. The change in characteristics of the mode of interest with lowering of temperature has been observed and analyzed. Electron spin resonance spectra of a standard paramagnetic sample, 2,2-diphenyl-1-picrylhydrazyl, are recorded using this resonator down to 10 K. Potential application of the mode in the detection of microwave Rashba field-driven electron spin resonance has been discussed.

description: Controlled movement and manipulation of magnetic micro and nanostructures using magnetic forces can give rise to important applications in biomedecine, diagnostics and immunology. We report controlled magnetophoresis and stretching, in aqueous solution, of a DNA-based dumbbell structure containing magnetic and diamagnetic microspheres. The velocity and stretching of the dumbbell were experimentally measured and correlated with a theoretical model based on the forces acting on individual magnetic beads or the entire dumbbell structures. The results show that precise and predictable manipulation of dumbbell structures is achievable and can potentially be applied to immunomagnetic cell separators.

description: A major impediment towards realizing technologies based on the emerging principles of antiferromagnetic spintronics is the shortage of suitable materials. In this paper, we propose a design of polar|nonpolar heterostructures of perovskite oxides, where a single unit cell of SrIrO3 is sandwiched between a thin film of LaAlO3 and a substrate of SrTiO3. Our calculations within the framework of density-functional theory + Hubbard U + spin-orbit coupling reveal a two-dimensional conducting layer with electron and hole pockets at the interface, exhibiting a strong anisotropic Rashba-Dresselhaus effect along with noncollinear antiferromagnetism, indicating the possibility of realizing a spin-orbit torque. An insightful physical model for the anisotropic Rashba-Dresselhaus effect nicely interprets our results, providing an estimate for the Rashba-Dresselhaus coefficients and illustrating pseudospin orientation.We also observe a proximity-induced prominent Rashba-like effect for Ti 3d empty bands. Our results suggest that the heterostructure may possess the essential ingredients for antiferromagnetic spintronics, deserving experimental verification.

Application of simulated annealing to some seismic problems
Creators: name: Velis, Danilo Rubén
Publisher: name: University of British Columbia
Year: 2009

description: Wavelet estimation, ray tracing, and traveltime inversion are fundamental problems in seismic exploration. They can be finally reduced to minimizing a highly nonlinear cost function with respect to a certain set of unknown parameters. I use simulated annealing (SA) to avoid local minima and inaccurate solutions often arising by the use of linearizing methods. I illustrate all applications using numerical and/or real data examples. The first application concerns the 4th-order cumulant matching (CM) method for wavelet estimation. Here the reliability of the derived wavelets depends strongly on the amount of data. Tapering the trace cumulant estimate reduces significantly this dependency, and allows for a trace-by-trace implementation. For this purpose, a hybrid strategy that combines SA and gradient-based techniques provides efficiency and accuracy. In the second application I present SART (SA ray tracing), which is a novel method for solving the two-point ray tracing problem. SART overcomes some well known difficulties in standard methods, such as the selection of new take-off angles, and the multipathing problem. SA finds the take-off angles so that the total traveltime between the endpoints is a global minimum. SART is suitable for tracing direct, reflected, and headwaves, through complex 2-D and 3-D media. I also develop a versatile model representation in terms of a number of regions delimited by curved interfaces. Traveltime tomography is the third SA application. I parameterize the subsurface geology by using adaptive-grid bicubic B-splines for smooth models, or parametric 2-D functions for anomaly bodies. The second approach may find application in archaeological and other near-surface studies. The nonlinear inversion process attempts to minimize the rms error between observed and predicted traveltimes.

CoO2-Layer-Thickness Dependence of Magnetic Properties and Possible Two Different Superconducting States in NaxCoO2.yH2O

description: In order to understand the experimentally proposed phase diagrams of NaxCoO2.yH2O, we theoretically study the CoO2-layer-thickness dependence of magnetic and superconducting (SC) properties by analyzing a multiorbital Hubbard model using the random phase approximation. When the Co valence (s) is +3.4, we show that the magnetic fluctuation exhibits strong layer-thickness dependence where it is enhanced at finite (zero) momentum in the thicker (thinner) layer system. A magnetic order phase appears sandwiched by two SC phases, consistent with the experiments. These two SC phases have different pairing states where one is the singlet extended s-wave state and the other is the triplet p-wave state. On the other hand, only a triplet p-wave SC phase with dome-shaped behavior of Tc is predicted when s=+3.5, which is also consistent with the experiments. Controversial experimental results on the magnetic properties are also discussed.

description: It is well known that an arbitrary graphical model of statistical inference defined on a tree, i.e. on a graph without loops, is solved exactly and efficiently by an iterative Belief Propagation (BP) algorithm convergent to unique minimum of the so-called Bethe free energy functional. For a general graphical model on a loopy graph the functional may show multiple minima, the iterative BP algorithm may converge to one of the minima or may not converge at all, and the global minimum of the Bethe free energy functional is not guaranteed to correspond to the optimal Maximum-Likelihood (ML) solution in the zero-temperature limit. However, there are exceptions to this general rule, discussed in \cite{05KW} and \cite{08BSS} in two different contexts, where zero-temperature version of the BP algorithm finds ML solution for special models on graphs with loops. These two models share a key feature: their ML solutions can be found by an efficient Linear Programming (LP) algorithm with a Totally-Uni-Modular (TUM) matrix of constraints. Generalizing the two models we consider a class of graphical models reducible in the zero temperature limit to LP with TUM constraints. Assuming that a gedanken algorithm, g-BP, funding the global minimum of the Bethe free energy is available we show that in the limit of zero temperature g-BP outputs the ML solution. Our consideration is based on equivalence established between gapless Linear Programming (LP) relaxation of the graphical model in the $T\to 0$ limit and respective LP version of the Bethe-Free energy minimization.

Signatures of global symmetry violation in relative entropies and replica wormholes

description: It is widely believed that exact global symmetries do not exist in theories that admit quantum black holes. Here we propose a way to quantify the degree of global symmetry violation in the Hawking radiation of a black hole by using certain relative entropies. While the violations of global symmetry that we consider are non-perturbative effects, they nevertheless give $\mathcal{O}(1)$ contributions to the relative entropy after the Page time. Furthermore, using "island" formulas, these relative entropies can be computed within semi-classical gravity, which we demonstrate with explicit examples. These formulas give a rather precise operational sense to the statement that a global charge thrown into an old black hole will be lost after a scrambling time. The relative entropies considered here may also be computed using a replica trick. At integer replica index, the global symmetry violating effects manifest themselves as charge flowing through the replica wormhole.

'As a friend, as a trend, as an old memory' : popular music, memory and power

description: This thesis examines the relationship between memory and popular music. In order to make a claim for the validity of the field, popular music studies have often focused on the political and oppositional qualities of such music. It is argued in the thesis that although a form of popular culture such as grunge presents challenges to existing power relations, these challenges are often defused in the way grunge is remembered by the majority of fans. This is demonstrated through the examination of how collective memories are formed through the media, especially in dispersed groups, in contemporary societies. The formation of memory in this manner does not necessarily allow the media to control these memories or impose meaning, as memories are used to support and construct present identities. As a result, different groups may have different requirements of the past. The concept of memory is examined using the grunge musical 'movement' which was popular during the early 1990s. While exploring the sociology of memory, this thesis therefore also contributes to popular music studies, as few studies have investigated grunge in depth, or examined popular music retrospectively. The thesis uses interviews with grunge fans and content analysis of media articles about grunge as materials to explore the way popular culture is remembered. The main concepts used are collective memory, as theorised by Halbwachs and others, and Bourdieu's ideas of power, tastes and cultural fields. The thesis will use this context to demonstrate how gender roles can be reinscribed in retrospect, and how the life-stories of individuals can be used to reinforce prevailing myths and narratives within a society. It also suggests that class operates in a similar way through the influence that it has on tastes and lifestyles, as well as influencing what (and who) is remembered and the form that memory takes.

description: The problem of class imbalance is extensive for focusing on numerous applications in the real world. In such a situation, nearly all of the examples are labeled as one class called majority class, while far fewer examples are labeled as the other class usually, the more important class is called minority. Over the last few years, several types of research have been carried out on the issue of class imbalance, including data sampling, cost-sensitive analysis, Genetic Programming based models, bagging, boosting, etc. Nevertheless, in this survey paper, we enlisted the 24 related studies in the years 2003, 2008, 2010, 2012 and 2014 to 2019, focusing on the architecture of single, hybrid, and ensemble method design to understand the current status of improving classification output in machine learning techniques to fix problems with class imbalances. This survey paper also includes a statistical analysis of the classification algorithms under various methods and several other experimental conditions, as well as datasets used in different research papers.

description: This paper delves into educational technology focusing on educational software and information systems. There is a historical retrospection followed by a reference of the beneficial rewards and effects resulting from it. On that path, there is further examination of the ways and level that information technology has been incorporated into the cypriot public primary school. The examination uses the linguistic lesson as its field of focus and verifies the ways that learning theories and psychology are affecting the structure, development and evolution of the educational software available. Various models and criteria for the evaluation are presented. Finally, there are various suggestions regariding the improvement of the educational software

description: The distribution of the intensities of individual pulses of PSR B0950+08 as a function of the longitudes at which they appear is analyzed. The flux density of the pulsar at 111 MHz varies strongly from day to day (by up to a factor of 13) due to the passage of the radiation through the interstellar plasma (interstellar scintillation). The intensities of individual pulses can exceed the amplitude of the mean pulse profile, obtained by accumulating 770 pulses, by more than an order of magnitude. The intensity distribution along the mean profile is very different for weak and strong pulses. The differential distribution function for the intensities is a power law with index n = -1.1 +- 0.06 up to peak flux densities for individual pulses of the order of 160 Jy.

description: The death of massive stars is shrouded in many mysteries. One of them is the mechanism that overturns the collapse of the degenerate iron core into an explosion, a process that determines the supernova explosion energy, properties of the surviving compact remnant, and the nucleosynthetic yields. The number of core-collapse supernova observations has been growing with an accelerating pace thanks to modern time-domain astronomical surveys and new tests of the explosion mechanism are becoming possible. We review predictions of parameterized supernova explosion models and compare them with explosion properties inferred from observed light curves, spectra, and neutron star masses.

description: Let K be a compact Lie group, endowed with a bi-invariant Riemannian metric. The complexification G of K inherits a Kaehler structure having twice the kinetic energy of the metric as its potential, and left and right translation turn the Hilbert space of square-integrable holomorphic functions on G relative to a suitable measure into a unitary (KxK)-representation. We establish the statement of the Peter-Weyl theorem for this Hilbert space to the effect that this Hilbert space contains the vector space of representative functions on G as a dense subspace and that the assignment to a holomorphic function of its Fourier coefficients yields an isomorphism of Hilbert algebras from the convolution algebra on G onto the algebra which arises from the endomorphism algebras of the irreducible representations of K by the appropriate operation of Hilbert space sum. Consequences are (i) a holomorphic Plancherel theorem and the existence of a uniquely determined unitary isomorphism between the space of square-integrable functions on K and the Hilbert space of holomorphic functions on G, and (ii) a proof that this isomorphism coincides with the corresponding Blattner-Kostant-Sternberg pairing map, multiplied by a suitable constant. We then show that the spectral decomposition of the energy operator on the Hilbert space of holomorphic functions on G associated with the metric on K refines to the Peter-Weyl decomposition of this Hilbert space in the usual manner and thus yields the decomposition of this Hilbert space into irreducible isotypical (KxK)-representations. Among our crucial tools is Kirillov's character formula. Our methods are geometric and independent of heat kernels, which are used by B. C. Hall to obtain many of these results [Journal of Functional Analysis 122 (1994), 103--151], [Comm. in Math. Physics 226 (2002), 233--268].

description: We present here a novel resist formulation with active thiol groups at the surface. The material is UV curable, and can be patterned at the micro- and nanoscale by UV nanoimprint lithography. The resist formulation development, its processing, patterning and surface characterization are presented here. In addition, a possible application, including its use to modify the electrical properties of graphene devices is shown. The cured material is highly transparent, intrinsically hydrophilic and can be made more hydrophilic following a UV-ozone or an O2 plasma activation. We evaluated the hydrophilicity of the polymer for different polymer formulations and curing conditions. In addition, a protocol for patterning of the polymer in the micro and nanoscale by nanoimprinting is given and preliminary etching rates together with the polymer selectivity are measured. The main characteristic and unique advantage of the polymer is that it has thiol functional groups at the surface and in the bulk after curing. These groups allow for direct surface modifications with thiol-based chemistry e.g., thiol-ene reactions. We prove the presence of the thiol groups by Raman spectroscopy and perform a thiol-ene reaction to show the potential of the easy click chemistry. This opens the way for very straightforward surface chemistry on nanoimprinted polymer samples. Furthermore, we show how the polymer improves the electrical properties of a graphene field effect transistor, allowing for optimal performance at ambient conditions.
Nitrogenous nutrition of phytoplankton from the Northeastern subarctic Pacific Ocean

description: The goals o f this thesis were to investigate the uptake rates of inorganic and organic forms of nitrogen, the relative proportions of new and regenerated primary production, and the interactions between uptake of ammonium and nitrate by phytoplankton from the NE subarctic Pacific Ocean. Nitrogen uptake rates, and physical, chemical and biological characteristics of the euphotic zone were studied during winter, spring and late summer for two years along a transect extending from 49°N, 127°W to 50°N, 145°W. New and regenerated primary production were estimated by means of 1 S N isotopes. Ammonium (NH₄⁺) was usually taken up at the highest rates throughout the euphotic zone during all seasons. Urea uptake rates were lower than those of NH₄⁺, but higher values were occasionally observed, particularly during the spring of 1993. Nitrate (N0₃⁻) uptakerates represented on average 21% of the depth integrated total nitrogen uptake, both longitudinally and seasonally. The ∫ - ratio was overestimated on average by 36% when urea was excluded from the calculation. The order of preference for nitrogen by the entire phytoplankton assemblage was NH4urea > N0₃⁻. This system functioned mainly on regenerated nitrogen forms year round, despite the availability of N0₃⁻ in most of the region. Small (< 2 μm) and large (> 2 μm) phytoplankton took up NH₄⁺ at higher rates than urea and N03 \ Depth integrated/-ratios were 0.16 for small cells and 0.25 for large cells. The order of preference for the nitrogen sources by small cells was NH₄⁺ > urea > N0₃⁻, and by larger cells it was NH₄⁺ = urea > N0₃⁻ Picoplankton were responsible for the greatest proportion of new and regenerated primary production. The presence of NH₄⁺ inhibited N0₃⁻ uptake in the coccolithophore, Emiliania huxleyi. Nitrate uptake rates were reduced to half the maximum value at 0.24 μm NH₄⁺, and maximum inhibition was ∼100% at 2.2 NH₄⁺ . Extrapolating this laboratory result to field conditions, the inhibition of N0₃⁻ uptake rates for the small size class of phytoplankton is predicted to be 37 to 69% for the range of ambient NH₄⁺ concentrations found in the NE subarctic Pacific.

Large-scale electronic structure theory for simulating nanostructure process

description: Fundamental theories and practical methods for large-scale electronic structure calculations are given, in which the computational cost is proportional to the system size. Accuracy controlling methods for microscopic freedoms are focused on two practical solver methods, Krylov-subspace method and generalized-Wannier-state method. A general theory called the 'multi-solver' scheme is also formulated, as a hybrid between different solver methods. Practical examples are carried out in several insulating and metallic systems with 10^3-10^5 atoms. All the theories provide general guiding principles of constructing an optimal calculation for simulating nanostructure processes, since a nanostructured system consists of several competitive regions, such as bulk and surface regions, and the simulation is designed to reproduce the competition with an optimal computational cost.

description: We consider the fundamental problem of estimating the mean of a vector $y=Xβ+z$, where $X$ is an $n\times p$ design matrix in which one can have far more variables than observations, and $z$ is a stochastic error term--the so-called "$p>n$" setup. When $β$ is sparse, or, more generally, when there is a sparse subset of covariates providing a close approximation to the unknown mean vector, we ask whether or not it is possible to accurately estimate $Xβ$ using a computationally tractable algorithm. We show that, in a surprisingly wide range of situations, the lasso happens to nearly select the best subset of variables. Quantitatively speaking, we prove that solving a simple quadratic program achieves a squared error within a logarithmic factor of the ideal mean squared error that one would achieve with an oracle supplying perfect information about which variables should and should not be included in the model. Interestingly, our results describe the average performance of the lasso; that is, the performance one can expect in an vast majority of cases where $Xβ$ is a sparse or nearly sparse superposition of variables, but not in all cases. Our results are nonasymptotic and widely applicable, since they simply require that pairs of predictor variables are not too collinear.
