description: The polaron to bipolaron transition in disordered media under the influence of a broadband ac electric field is suggested: ac conductivity vs. frequency measurements in disordered media with inhomogeneous disorder induce spatio-temporal fluctuations of the density of polarons yielding polaron to bipolaron transformation. The external field results in the transition, alternatively to an increasing doping level. The assertion is confirmed by performing successive complex impedance measurements in disordered media. A systematic increase of the real part of the ac conductivity in the frequency domain, followed by mutual reduction of the magnetic inductivity of conducting polypyrrole, are explained.

description: This work proposes a study of the planning of the Roman Dertona, today Tortona, in Piemonte, according to three possibilities. We will see its layout in function of the natural environment which is surrounding it (secundum naturam), of the roman roads which were passing thorough the area, and according to a possible astronomical orientation (secundum coelum). This last analysis will allow us to define a possible year for the foundation of the town.

description: The aim of the present paper is to provide an \emph{intrinsic} investigation of the properties of the most important geometric objects associated with the fundamental linear connections in Finsler geometry. We investigate intrinsically the most general relations concerning the torsion tensor fields and the curvature tensor fields associated with a given regular connection on the pullback bundle of a Finsler manifold. These relations, in turn, play a key role in obtaining other interesting results concerning the properties of the most important geometric objects associated with the fundamental canonical linear connections on the pullback bundle of a Finsler manifold, namely, the Cartan connection, the Berwald connection, the Chern (Rund) connection and the Hashiguchi connection. For the sake of completeness and for comparison reasons, we provide an appendix presenting a global survey of canonical linear connections in Finsler geometry and the fundamental geometric objects associated with them.

description: The theory of optical dispersive shocks generated in propagation of light beams through photorefractive media is developed. Full one-dimensional analytical theory based on the Whitham modulation approach is given for the simplest case of sharp step-like initial discontinuity in a beam with one-dimensional strip-like geometry. This approach is confirmed by numerical simulations which are extended also to beams with cylindrical symmetry. The theory explains recent experiments where such dispersive shock waves have been observed.

description: Many types of motile cells perform durotaxis, namely, directed migration following gradients of substrate stiffness. Recent experiments have revealed that cell monolayers can migrate toward stiffer regions even when individual cells do not -- a phenomenon known as collective durotaxis. Here we address the spontaneous motion of finite cohesive cell monolayers on a stiffness gradient. We theoretically analyze a continuum active polar fluid model that has been tested in recent wetting assays of epithelial tissues, and includes two types of active forces (cell-substrate traction and cell-cell contractility). The competition between the two active forces determines whether a cell monolayer spreads or contracts. Here, we show that this model generically predicts collective durotaxis, and that it features a variety of dynamical regimes as a result of the interplay between the spreading state and the global propagation, including sequential contraction and spreading of the monolayer as it moves toward higher stiffness. We solve the model exactly in some relevant cases, which provides both physical insights into the mechanisms of tissue durotaxis and spreading as well as a variety of predictions that could guide the design of future experiments.

description: We discuss the use of multivariate kernel smoothing methods to date manuscripts dating from the 11th to the 15th centuries, in the English county of Essex. The dataset consists of some 3300 dated and 5000 undated manuscripts, and the former are used as a training sample for imputing dates for the latter. It is assumed that two manuscripts that are ``close'', in a sense that may be defined by a vector of measures of distance for documents, will have close dates. Using this approach, statistical ideas are used to assess ``similarity'', by smoothing among distance measures, and thus to estimate dates for the 5000 undated manuscripts by reference to the dated ones.

The effect of item format on mathematics achievement set scores
Creators: name: Dukowski, Leslie Hubert
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the study was to determine whether item format significantly affected scores on a mathematics achievement test. A forty-two item test was constructed and cast in both multiple-choice and constructed-response formats. The items were chosen in such a way that in each of three content domains, Computation, Application, and Algebra, there were seven items at each of two difficulty levels. The two tests were then administered on separate occasions to a sample of 213 Grade 7 students from a suburban/ rural community in British Columbia, Canada. The data gathered was analysed according to a repeated measures analysis of variance procedure using item format and item difficulty as trial factors and using student ability and gender as grouping factors. Item format did have a significant (p < 0.05) effect on test score. In all domains multiple-choice scores were higher than constructed-response scores. The multiple-choice scores were also transformed using the traditional correction for guessing procedure and analysed. Multiple-choice scores were still significantly higher in two of the three domains, Application and Algebra. There were significant omnibus F-statistics obtained for a number of interactions for both corrected and uncorrected data but there were significant Tetrad differences (p < 0.10) only for interactions involving format and difficulty. The results indicate that students score higher on a multiple-choice form of a mathematics achievement test than on a constructed-response form, and therefore the two scores cannot be considered equal or interchangeable. However, because of the lack of interactions involving format, the two scores may be considered equivalent in the sense that they rank students in the same manner and that the intervals between scores may be interpretable in the same manner under both formats. Therefore, although the traditional correction for chance formula is not sufficient to remove differences between multiple-choice and constructed-response scores, it may be possible to derive an empirical scoring formula which would equate the two types of scores on a particular test.

description: Perfusion imaging is an interesting new modality for evaluation and assessment of the liver cancer treatment. C-Arm CT provides a possibility to perform perfusion imaging scans intra-operatively for even faster evaluation. The slow speed of the C-Arm CT rotation and the presence of the noise, however, have an impact on the reconstruction and therefore model based approaches have to be applied. In this work we apply the Time separation technique (TST), to denoise data, speed up reconstruction and improve resulting perfusion images. We show on animal experiment data that Dynamic C-Arm CT Liver Perfusion Imaging together with the processing of the data based on the TST provides comparable results to standard CT liver perfusion imaging.

description: Lanthanide luminescent complexes offer great potential as diagnostic agents. Thanks to low photobleaching, large Stokes shifts, long lifetimes, and emission tunability, they provide advantages compared to organic chromophores. However, the synthetic design requires careful consideration to generate stable and inert complexes using appropriate ligands that can fulfil the lanthanide coordination sphere, while sensitizing metal-centred luminescence. Moreover, to obtain suitable diagnostic agents for cancer, the overall probe must selectively detect tumour cells. Vitamin B12 (aka cyanocobalamin) is an essential nutrient with very low bioavailability. Since tumour cells require higher amounts of cyanocobalamin to support their abnormal proliferation rate, it turns out to be a very attractive carrier for conjugation to rationally designed imaging agents, to specifically target tumour sites. Vitamin B12 can be functionalized at the 5’-hydroxo group of the ribose unit with a suitable luminescent probe through a rigid linker without affecting its recognition by transport proteins. Starting from this rationale, the present PhD research work focuses on the design and synthesis of luminescent lanthanide-vitamin B12 imaging agents in which the cyanocobalamin scaffold would be functionalized with selected non-toxic lanthanide (III)-DOTA-based luminescent probes with a focus on Eu(III), Tb(III) and Gd(III). The goal is to take advantage of the increased demand for vitamin B12 in tumours by exploiting its carrier properties to generate site-specific “Trojan Horse”-type diagnostic bioconjugates. Preliminary in vitro cytotoxicity studies are presented towards MCF-7 cells showing a dose-dependency toxicity only when the carrier is incorporated. No fluorescence was detected with optical microscope in vitro, hence more analysis using confocal microscope are required to confirm the efficiency of the probes as luminescent agents.

description: Graph neural networks (GNNs) emerge as a powerful family of representation learning models on graphs. To derive node representations, they utilize a global model that recursively aggregates information from the neighboring nodes. However, different nodes reside at different parts of the graph in different local contexts, making their distributions vary across the graph. Ideally, how a node receives its neighborhood information should be a function of its local context, to diverge from the global GNN model shared by all nodes. To utilize node locality without overfitting, we propose a node-wise localization of GNNs by accounting for both global and local aspects of the graph. Globally, all nodes on the graph depend on an underlying global GNN to encode the general patterns across the graph; locally, each node is localized into a unique model as a function of the global model and its local context. Finally, we conduct extensive experiments on four benchmark graphs, and consistently obtain promising performance surpassing the state-of-the-art GNNs.

description: We construct in a systematic way the complete Chevalley-Eilenberg cohomology at form degree two, three and four for the Galilei and Poincare groups. The corresponding non-trivial forms belong to certain representations of the spatial rotation (Lorentz) group. In the case of two forms they give all possible central and non-central extensions of the Galilei group (and all non-central extensions of the Poincare group). The procedure developed in this paper can be applied to any space-time symmetry group.

Theoretical analysis of Fresnel reflection and transmission in the presence of gain media

description: When a monochromatic electromagnetic plane-wave arrives at the flat interface between its transparent host (i.e., the incidence medium) and an amplifying (or gainy) second medium, the incident beam splits into a reflected wave and a transmitted wave. In general, there is a sign ambiguity in connection with the k-vector of the transmitted beam, which requires at the outset that one decide whether the transmitted beam should grow or decay as it recedes from the interface. The question has been posed and addressed most prominently in the context of incidence at large angles from a dielectric medium of high refractive index onto a gain medium of lower refractive index. Here, the relevant sign of the transmitted k-vector determines whether the evanescent-like waves within the gain medium exponentially grow or decay away from the interface. We examine this and related problems in a more general setting, where the incident beam is taken to be a finite-duration wavepacket whose footprint in the interfacial plane has a finite width. Cases of reflection from and transmission through a gainy slab of finite-thickness as well as those associated with a semi-infinite gain medium will be considered. The broadness of the spatiotemporal spectrum of our incident wavepacket demands that we develop a general strategy for deciding the signs of all the k-vectors that enter the gain medium. Such a strategy emerges from a consideration of the causality constraint that is naturally imposed on both the reflected and transmitted wavepackets.

description: In this paper, we accomplish a unified convergence analysis of a second-order method of multipliers (i.e., a second-order augmented Lagrangian method) for solving the conventional nonlinear conic optimization problems.Specifically, the algorithm that we investigated incorporates a specially designed nonsmooth (generalized) Newton step to furnish a second-order update rule for the multipliers.We first show in a unified fashion that under a few abstract assumptions, the proposed method is locally convergent and possesses a (nonasymptotic) superlinear convergence rate, even though the penalty parameter is fixed and/or the strict complementarity fails.Subsequently, we demonstrate that, for the three typical scenarios, i.e., the classic nonlinear programming, the nonlinear second-order cone programming, and the nonlinear semidefinite programming, these abstract assumptions are nothing but exactly the implications of the iconic sufficient conditions that were assumed for establishing the Q-linear convergence rates of the method of multipliers without assuming the strict complementarity.

description: We compare the structure of the tree level scattering amplitudes in non-Abelian tensor gauge field theory and in open string theory with Chan-Paton charges. We limit ourselves considering only lower rank tensor fields in both theories. We identify the symmetric and antisymmetric components of the second rank tensor gauge field with the string excitations on the third and forth levels. In the process of this identification we have been selecting only those parts of the tree level scattering amplitudes in the open string theory which have dimensionless coupling constants in four dimensions. It seems that this subclass of tree level scattering amplitudes may provide important information about the structure of the open string theory and most probably it is equivalent to the non-Abelian tensor gauge field theory.

description: The emerging cryptocurrency market has lately received great attention for asset allocation due to its decentralization uniqueness. However, its volatility and brand new trading mode have made it challenging to devising an acceptable automatically-generating strategy. This study proposes a framework for automatic high-frequency bitcoin transactions based on a deep reinforcement learning algorithm-proximal policy optimization (PPO). The framework creatively regards the transaction process as actions, returns as awards and prices as states to align with the idea of reinforcement learning. It compares advanced machine learning-based models for static price predictions including support vector machine (SVM), multi-layer perceptron (MLP), long short-term memory (LSTM), temporal convolutional network (TCN), and Transformer by applying them to the real-time bitcoin price and the experimental results demonstrate that LSTM outperforms. Then an automatically-generating transaction strategy is constructed building on PPO with LSTM as the basis to construct the policy. Extensive empirical studies validate that the proposed method performs superiorly to various common trading strategy benchmarks for a single financial product. The approach is able to trade bitcoins in a simulated environment with synchronous data and obtains a 31.67% more return than that of the best benchmark, improving the benchmark by 12.75%. The proposed framework can earn excess returns through both the period of volatility and surge, which opens the door to research on building a single cryptocurrency trading strategy based on deep learning. Visualizations of trading the process show how the model handles high-frequency transactions to provide inspiration and demonstrate that it can be expanded to other financial products.

Basic concepts for art curricula development in neo-calvinistic education
Creators: name: Dykstra, Gerry
Publisher: name: University of British Columbia
Year: 2010

description: In this study a comparative evaluation of several views on art education that include social concerns is presented. These are expressed as concern for the aesthetic qualities of the contemporary man-made environment, the artistic heritage of the nation, the cultural values of ethnic and social groups and the moral responsibility of the individual in society. Views of four North American art educators are examined in relation to their concepts of society, education and art. In this examination emphasis is given to the identification of the different aspects of human experience such as the cognitive aspect, the linguistic aspect, the social aspect, the aesthetic aspect and the moral aspect. Because all these aspects of human experience relate to the objects of the man-made environment, the author presents an analysis of individual things and their functions in the context of human experience from the perspective of Neo-Calvinistic philosophy. Some fundamental concepts, basic to this philosophy, are conveyed in a historical survey that includes the development of Neo-Calvinism in the Netherlands and North America. The analysis of individual things is presented in terms of Dooyeweerd's theory of modal structure. This theory is part of the Philosophy of the Cosmonomic Idea, which was developed during the nineteen thirties and formed a major role in the development of a Neo-Calvinistic philosophical movement. In this theory it is argued that the aesthetic aspect functions in relation to all things, but that this relationship is not the same in every case. The primary function of each individual thing determines whether the aesthetic aspect has a subordinate or leading role in the object. Proceeding from this theory it is posited that art education in Neo-Calvinistic schools incorporate two different art curricula; a "free-art" curriculum that focuses on those objects in which the aesthetic aspect has the leading function, and another curriculum, called a "bound-art" curriculum, that stresses the study of the aesthetic aspect in subordination to the other functions of objects. The theory of modal structure also applies to the different social groups of society. Each group has its own primary function. This function gives direction to the aesthetic aspect of the individual objects belonging to the group. The social concerns in Neo-Calvinistic art education therefore are presented within context of the leading function of the different groups in society. The implications of the modal structure and the views of the art educators convened in this study are mentioned throughout the presentation of this thesis.

Interaction Correction of Conductivity Near a Ferromagnetic Quantum Critical Point

description: We calculate the temperature dependence of conductivity due to interaction correction for a disordered itinerant electron system close to a ferromagnetic quantum critical point which occurs due to a spin density wave instability. In the quantum critical regime, the crossover between diffusive and ballistic transport occurs at a temperature $T^{\ast}=1/[τγ(E_{F}τ)^{2}]$, where $γ$ is the parameter associated with the Landau damping of the spin fluctuations, $τ$ is the impurity scattering time, and $E_{F}$ is the Fermi energy. For a generic choice of parameters, $T^{\ast}$ is few orders of magnitude smaller than the usual crossover scale $1/τ$. In the ballistic quantum critical regime, the conductivity has a $T^{(d-1)/3}$ temperature dependence, where $d$ is the dimensionality of the system. In the diffusive quantum critical regime we get $T^{1/4}$ dependence in three dimensions, and $\ln^2 T$ dependence in two dimensions. Away from the quantum critical regime we recover the standard results for a good metal.

description: Ethereum relies on a peer-to-peer overlay network to propagate information. The knowledge of Ethereum network topology holds the key to understanding Ethereum's security, availability, and user anonymity. From a measurement perspective, an Ethereum network's topology is routing-table information hidden inside individual Ethereum nodes, measuring which poses challenges and remains an open research problem in the existing literature. This paper presents TopoShot, a new method uniquely repurposing Ethereum's transaction replacement/eviction policies for topology measurement. TopoShot can be configured to support Geth, Parity, and other major Ethereum clients. As validated on local nodes, TopoShot achieves 100% measurement precision and high recall 88% - 97%. To efficiently measure the large Ethereum networks in the wild, we propose a non-trivial schedule to run pair-wise measurements in parallel. To enable ethical measurement on Ethereum mainnet, we propose workload-adaptive configurations of TopoShot to minimize the service interruption to target nodes/network. We systematically measure a variety of Ethereum networks and obtain new knowledge including the full-network topology in major testnets (Ropsten, Rinkeby and Goerli) and critical sub-network topology in the mainnet. The results on testnets show interesting graph-theoretic properties, such as all testnets exhibit graph modularity significantly lower than random graphs, implying resilience to network partitions. The mainnet results show biased neighbor selection strategies adopted by critical Ethereum services such as mining pools and transaction relays, implying a degree of centralization in real Ethereum networks.

description: Traffic forecasting is an integral part of intelligent transportation systems (ITS). Achieving a high prediction accuracy is a challenging task due to a high level of dynamics and complex spatial-temporal dependency of road networks. For this task, we propose Graph Attention-Convolution-Attention Networks (GACAN). The model uses a novel Att-Conv-Att (ACA) block which contains two graph attention layers and one spectral-based GCN layer sandwiched in between. The graph attention layers are meant to capture temporal features while the spectral-based GCN layer is meant to capture spatial features. The main novelty of the model is the integration of time series of four different time granularities: the original time series, together with hourly, daily, and weekly time series. Unlike previous work that used multi-granularity time series by handling every time series separately, GACAN combines the outcome of processing all time series after each graph attention layer. Thus, the effects of different time granularities are integrated throughout the model. We perform a series of experiments on three real-world datasets. The experimental results verify the advantage of using multi-granularity time series and that the proposed GACAN model outperforms the state-of-the-art baselines.

description: Oxide based ferromagnet/semiconductor heterostructures offer substantial advantages for spin electronics. We have grown (111) oriented Fe3O4 thin films and Fe3O4/ZnO heterostructures on ZnO(0001) and Al2O3(0001) substrates by pulsed laser deposition. High quality crystalline films with mosaic spread as small as 0.03 degree, sharp interfaces, and rms surface roughness of 0.3 nm were achieved. Magnetization measurements show clear ferromagnetic behavior of the magnetite layers with a saturation magnetization of 3.2 muB/f.u. at 300 K. Our results demonstrate that the Fe3O4/ZnO system is an intriguing and promising candidate for the realization of multi-functional heterostructures.
