description: The design of catalysts with desired chemical and thermal properties is viewed as a grand challenge for scientists and engineers. For operation at high temperatures, stability against structural transformations is a key requirement. Although doping has been found to impede degradation, the lack of atomistic understanding of the pertinent mechanism has hindered optimization. For example, porous gamma-Al2O3, a widely used catalyst and catalytic support, transforms to non-porous alpha-Al2O3 at ~1,100C. Doping with La raises the transformation temperature to ~1,250C, but it has not been possible to establish if La atoms enter the bulk, adsorb on surfaces as single atoms or clusters, or form surface compounds. Here, we use direct imaging by aberration-corrected Z-contrast scanning transmission electron microscopy coupled with extended X-ray absorption fine structure and first-principles calculations to demonstrate that, contrary to expectations, stabilization is achieved by isolated La atoms adsorbed on the surface. Strong binding and mutual repulsion of La atoms effectively pin the surface and inhibit both sintering and the transformation to alpha-Al2O3. The results provide the first guidelines for the choice of dopants to prevent thermal degradation of catalysts and other porous materials.

description: Many researches have been done concerning the study of parameters which make people choose or not such product on the market. Concerning food industry, scientists have been involved in the analysis of technical parameters (nutrition, health characteristics) and their perception by the consumer, and in the analysis of psycho-sociological parameters linked with the perception of the product, or emotion associated with food or its environment. Other parameters investigated are suspicion of novelties, adherence to technology or to natural food, enjoyment, necessity. But what about the effect of words from the socio-psycholinguistic standpoint? It seems to be poorly investigated. Some claims: “It doesn’t matter how important the brand name is to the company, it’s what it means to the public that counts”. Concerning the foreign migration of brands (the use of a brand from one country to another), some psychological functions associated with language are weakened in the communication process. If an undesirable link is built between the concept of the brand and another one in the target foreign market, this can come from some communication channels detailed in this study. The weakened psychological functions can be some of the causes, and the undesirable link built through the communication channels is the consequence. It is shown why unexpected links between the brand (or the product name) and an undesirable concept must be looked for in six dimensions (academic, common, popular, rude language, slang, and “no meaning” language), and how an adapted advertisement campaign can enforced the psychological functions associated with language.

description: This paper presents a theoretical discussion concerning possibilities for designing environmental value articulation procedures that respect the basic non-economic character of ecological phenomena. The question of how to estimate the economic value of ecosystem services contributions is a particularly important issue for agricultural economics because of the dependence of agricultural production on the life cycles and biological viability of ecosystems (sic Georgescu-Roegen, 1966). Distinguishing between two basic types of ecosystem services values – demand vs supply based – this paper aims to describe a theoretical context within which it may be possible to develop recommendations regarding procedures and associated institutional structures that can support the expression of economically relevant measures of the economic worth of a given ecological phenomena that are also ecologically sound. Finally it is proposed that there are strong synergies between the problem structure of this issue and the theoretical contributions of Herbert Simon, concerning bounded rationality and further work on the details of these links is recommended.

We illustrate our general results in various examples involving D-branes in toric orientifolds. We perform the computations by using both the topological vertex and unoriented localization. We also present an application of our results to the BPS structure of the coloured Kauffman polynomial of knots.

description: This paper analyses the asymmetric price transmission and non-linear adjustment at the farm and retail levels in the Iran’s mutton market. We applied a multivariate threshold error correction mechanism for monthly price data. We tested the non-linear adjustment using sup-LR, sup-LM and sup-Wald tests. The results confirm the presence of non-linear cointegration relationship between the retail and farm prices. In short-run, the price transmission behavior reveals that reactions of both the retail and farm prices to positive and negative deviations from the long-run price spread are asymmetric. More specially, the retailers show more strong responses to the both positive and negative shocks imposed to the farmers.

description: In this Letter we show that a single rectangular hole exhibits transmission resonances that appear near the cutoff wavelength of the hole waveguide. For light polarized with the electric field pointing along the short axis, it is shown that the normalized-to-area transmittance at resonance is proportional to the ratio between the long and short sides, and to the dielectric constant inside the hole. Importantly, this resonant transmission process is accompanied by a huge enhancement of the electric field at both entrance and exit interfaces of the hole. These findings open the possibility of using rectangular holes for spectroscopic purposes or for exploring non-linear effects.

Are rotation curves in NGC 6946 and the Milky Way magnetically supported?

Year: 2005

description: Following the model of magnetically supported rotation of spiral galaxies, the inner disk rotation is dominated by gravity but magnetism is not negligible at radii where the rotation curve becomes flat, and indeed becomes dominant at very large radii. Values of the order of 1 $μ$G, or even less, produce a centripetal force when the absolute value of the slope of the curve [$B_ϕ$, R] (azimuthal field strength versus radius) is less than $R^{-1}$. The $R^{-1}$-profile is called the critical profile. From this hypothesis, the following is to be expected: at large radii, a ``subcritical'' profile (slope flatter than $R^{-1}$); at still larger radii a $B_ϕ$-profile becoming asymptotically critical as the density becomes asymptotically vanishing. Recent observations of magnetic fields in NGC 6946 and the Milky Way are in very good agreement with these predictions. This magnetic alternative requires neither galactic dark matter (DM) nor modification of fundamental laws of physics, but it is not in conflict with these hypotheses, especially with the existence of cosmological cold dark matter (CDM).

description: Here, a novel energy trading system is proposed for demand-side management of a neighborhood area network (NAN) consisting of a shared energy storage (SES) provider, users with non-dispatchable energy generation, and an electricity retailer. In a leader-follower Stackelberg game, the SES provider first maximizes their revenue by setting a price signal and trading energy with the grid. Then, by following the SES provider's actions, the retailer minimizes social cost for the users, i.e., the sum of the total users' cost when they interact with the SES and the total cost for supplying grid energy to the users. A pricing strategy, which incorporates mechanism design, is proposed to make the system incentive-compatible by rewarding users who disclose true energy usage information. A unique Stackelberg equilibrium is achieved where the SES provider's revenue is maximized and the user-level social cost is minimized, which also rewards the retailer. A case study with realistic energy demand and generation data demonstrates 28\%~-~45\% peak demand reduction of the NAN, depending on the number of participating users, compared to a system without SES. Simulation results confirm that the retailer can also benefit financially, in addition to the SES provider and the users.

description: In order to stabilize and improve their income situation, rural households are strongly encouraged to diversify their activities both in and outside the agricultural sector. Most often, however, this phenomenon takes on only moderate proportions. This paper addresses issues of rural households’ income diversification in the case of Poland. It investigates returns from rural households’ income strategies using propensity score matching methods and extensive datasets spanning 1998-2008. Results suggest that returns from combining farm and off-farm activities were lower than returns from specialization, namely, concentrating on farming or on off-farm activities. Generally, farming seems to be the most attractive option for rural households and income difference between farmers and those who combine farming and off-farm activities increased after Poland joined the EU.

description: Smallholder farmers’ access to markets and agricultural support services has been a major concern of Zambian policy makers. As with many governments in Sub-Saharan Africa, the Zambian government’s agricultural policies, particularly for maize, have fundamentally been conceived of as a response to perceived market failure and weak access to markets for rural smallholder farmers. However, the conventional wisdom of poor market access is based on extremely limited empirical evidence. This study is motivated by the need to overcome this paucity of empirical evidence and provide policy makers with an up-to-date assessment of smallholder farmers’ market access conditions for maize, the primary food grain in Zambia.

description: In this thesis we investigate in detail the theory and practice of weight learning in LP MLN for collective classification problems. We test different weight learning methods on a practical collective classification problem, namely object labeling in images using relational context constraints, based on an exposition of the theory of weight learning in LP MLN. In our experiments we consider the applicability of different systems for weight learning in LP MLN and evaluate the performance of different weight learning methods in different scenarios. As we show, the best learning method depends very much on the input program and the specific dataset, and no single method noticeably outperforms other methods in our tests, with very simple learning methods performing very well. The performance of different methods can be very hard to predict, as some of our results are very unexpected. Nonetheless, from our experiments we conclude that weight learning noticeably improves the performance of an LP MLN-program in a collective classification setup and that effective weight learning methods and systems exist for LP MLN .

description: Deregulation of the Australian dairy industry, specifically the removal of price subsidies to ‘market milk’, as well as ongoing drought in many dairy regions, has placed considerable pressure on farm cash income and a search for ways in which dairy farms can be made to operate more efficiently. Using traditional farm survey data and a unique biannual data set on farm technology use, this paper estimates a stochastic production frontier and technical efficiency model for dairy farms in New South Wales and Victoria, determining the relative importance of each input in dairy production, the effects of key technology variables on farm efficiency, and overall farm profiles based on the efficiency rankings of dairy producers. Results show that production exhibits constant returns to scale and although feed concentration and the number of cows milked at peak season matter, the key determinants of differences in dairy farm efficiency are the type of dairy shed used and the proportion of irrigated farm area. Overall farm profiles indicate that those in the ‘high efficiency group’ largely employ either rotary or swing-over dairy shed technology and have almost three times the proportional amount of land under irrigation.

description: We present a formulation of N=(1,1) super Yang-Mills theory in 1+1 dimensions at finite temperature. The partition function is constructed by finding a numerical approximation to the entire spectrum. We solve numerically for the spectrum using Supersymmetric Discrete Light-Cone Quantization (SDLCQ) in the large-N_c approximation and calculate the density of states. We find that the density of states grows exponentially and the theory has a Hagedorn temperature, which we extract. We find that the Hagedorn temperature at infinite resolution is slightly less than one in units of (g^(2) N_c/pi)^(1/2). We use the density of states to also calculate a standard set of thermodynamic functions below the Hagedorn temperature. In this temperature range, we find that the thermodynamics is dominated by the massless states of the theory.

description: Sensitive data protection is essential for mobile users. Plausibly Deniable Encryption (PDE) systems provide an effective manner to protect sensitive data by hiding them on the device. However, existing PDE systems can lose data due to overriding the hidden volume, waste physical storage because of the reserved area used for avoiding data loss, and require device reboot when using the hidden volume. This paper presents MobiGyges, a hidden volume-based mobile PDE system, to fill the gap. MobiGyges addresses the problem of data loss by restricting each storage block used only by one volume, and it improves storage utilization by eliminating the reserved area. MobiGyges can also avoid device reboot by mounting the hidden volume dynamically on-demand with the Dynamic Mounting service. Moreover, we identify two novel PDE oriented attacks, the capacity comparison attack and the fill-to-full attack. MobiGyges can defend them by jointly leveraging the Shrunk U-disk method and multi-level deniability. We implement the MobiGyges proof-of-concept system on a real mobile phone Google Nexus 6P with LineageOS 13. Experimental results show that MobiGyges prevents data loss, avoids device reboot, improves storage utilization by over 30% with acceptable performance overhead compared with current works.

description: Heat propagation in quasi-one dimensional materials (Q1DMs) often appears paradoxical. While an isolated Q1DM, such as a nanowire, carbon nanotube, or polymer, can exhibit a high thermal conductivity \k{appa}, forests of the same materials show a reduction in \k{appa}. Here, the complex structures of these assemblies have hindered the emergence of a clear molecular picture of this intriguing phenomenon. We combine multiscale (coarse-grained) simulation with the concepts known from polymer physics and thermal transport to unveil a generic (microscopic) picture of \k{appa} reduction in molecular forests. We show that a delicate balance between the bond orientations, the persistence length of the Q1DM and the flexural vibrations govern the knock-down of \k{appa}.
Towards a landform geodatabase : the automatic identification of landforms
Creators: name: Maguire, Bradley David
Publisher: name: University of British Columbia
Year: 2009

description: If a geomorphologist is able to identify landforms from an aerial photograph or a Digital Terrain Model, then it should be possible for a computer to mimic the same process. The Landform Classification System (LCS) was created to allow for the automated identification of landforms from a Digital Terrain Model. The system uses a combination of a Network-Integrated Triangulated Irregular Network (NetTLN), a Fuzzy ARTMap Artificial Neural Network (ANN), and custom programming to produce a classification based on 22 morphometric variables, which describe the shape of the land surface. The ANN allows the system to "see" patterns in the morphometric variables. Once it has been trained with examples of different landform types, the ANN can perform a classification based on what it has learned. The LCS requires sufficient examples to produce high classification accuracies. Within the LCS, Kappa Analysis is used as the primary method for assessing classification accuracy. Kappa analysis takes into account the fact that even a random distribution of classified triangles may result in a few correct matches, so it is used as the primary measure of accuracy in this thesis. The K statistic produced by the Kappa Analysis decreases as we move from drumlins (8911 triangles) to eskers (193 triangles) and kames (11 triangles). The results for drumlins were best, with an Overall Accuracy value of 74.78% and a K accuracy value of 26.36%. For eskers, the values were 95.85% and 3.99% respectively. It should be noted that in spite of the low K values for eskers, the system has identified six potential eskers that were previously unidentified. For kames, the Overall Accuracy value was 98.47% and the K value was 0.00%, although this latter value is a reflection of the fact that no kames are known to exist on the map sheets that were classified. The Landform Classification System is reasonably fast at performing classifications. The ANN is currendy an external program; with some additional work, it can be incorporated directly into the LCS. Once this is done, the LCS should be fast enough to allow large areas to be classified. If the accuracy of the classifications can be improved somewhat, the Landform Classification System can then be used to produce a "Landform Geodatabase," which is a Geographical Information System (GIS) layer containing the type and extent of all landforms over a broad area. A short paper summarizing some of the results of this project to date was recendy presented at the Geotec 2005 conference in Vancouver. Entided "Development of the Landform Classification System," this paper summarizes some of the successes and problems that have surfaced in this project.

description: We have studied hadronic events from e+e- annihilation data at centre-of-mass energies from 91 to 209 GeV. We present distributions of event shape observables and their moments at each energy and compare with QCD Monte Carlo models. From the event shape distributions we extract the strong coupling alpha_s and test its evolution with energy scale. The results are consistent with the running of alpha_s expected from QCD. Combining all data, the value of alpha_s(M_Z) is determined to be alpha_s(M_Z) = 0.1191 +- 0.0005 (stat.) +- 0.0010 (expt.) +- 0.0011 (hadr.) +- 0.0044 (theo.). The energy evolution of the moments is also used to determine a value of alpha_s with slightly larger errors: alpha_s(M_Z) = 0.1223 +- 0.0005 (stat.) +- 0.0014 (expt.) +- 0.0016 (hadr.) +0.0054 -0.0036 (theo.).

description: Exploratory factor analysis is a dimension-reduction technique commonly used in psychology, finance, genomics, neuroscience, and economics. Advances in computational power have opened the door for fully Bayesian treatments of factor analysis. One open problem is enforcing rotational identifability of the latent factor loadings, as the loadings are not identified from the likelihood without further restrictions. Nonidentifability of the loadings can cause posterior multimodality, which can produce misleading posterior summaries. The positive-diagonal, lower-triangular (PLT) constraint is the most commonly used restriction to guarantee identifiability, in which the upper m × m submatrix of the loadings is constrained to be a lower-triangular matrix with positive-diagonal elements. The PLT constraint can fail to guarantee identifiability if the constrained submatrix is singular. Furthermore, though the PLT constraint addresses identifiability-related multimodality, it introduces additional mixing issues. We introduce a new Bayesian sampling algorithm that efficiently explores the multimodal posterior surface and addresses issues with PLT-constrained approaches.

description: We analyze squeezing of the nanoresonator state produced by periodic measurement of position by a quantum point contact or a single-electron transistor. The mechanism of squeezing is the stroboscopic quantum nondemolition measurement generalized to the case of continuous measurement by a weakly coupled detector. The magnitude of squeezing is calculated for the harmonic and stroboscopic modulations of measurement, taking into account detector efficiency and nanoresonator quality factor. We also analyze the operation of the quantum feedback, which prevents fluctuations of the wavepacket center due to measurement back-action. Verification of the squeezed state can be performed in almost the same way as its preparation; similar procedure can also be used for the force detection with sensitivity beyond the standard quantum limit.

description: This paper studies the feasibility of integrating a community energy storage (CES) system with rooftop photovoltaic (PV) power generation for demand-side management of a neighbourhood while maintaining the distribution network voltages within allowed limits. To this end, we develop a decentralized energy trading system between a CES provider and users with rooftop PV systems. By leveraging a linearized branch flow model for radial distribution networks, a voltage-constrained leader-follower Stackelberg game is developed wherein the CES provider maximizes revenue and the users minimize their personal energy costs by trading energy with the CES system and the grid. The Stackelberg game has a unique equilibrium at which the CES provider maximizes revenue and the users minimize energy costs at a unique Nash equilibrium. A case study, with realistic PV power generation and demand data, confirms that the energy trading system can reduce peak energy demand and prevent network voltage excursions, while delivering financial benefits to the users and the CES provider. Further, simulations highlight that, in comparison with a centralized system, the decentralized energy trading system provides greater economic benefits to the users with less energy storage capacity.

description: The use of marine protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a hypothetical predator–prey fishery is used to test the performance of protected areas in a fishery with heterogenous environments. Protected areas are analysed under density-dependent and sink-source dispersal relationships between the subpopulations that occur within the fishery. Differing management structures governing resource extraction are analysed. The focus of the study is placed on the biological and management characteristics that yield benefits to both fishers and society. It is shown that the establishment of a protected area improves fishery rent and lowers harvest variation. This result is sensitive to both current management controls and the correlation between species and patches.

description: Differential privacy (DP), provides a framework for provable privacy protection against arbitrary adversaries, while allowing the release of summary statistics and synthetic data. We address the problem of releasing a noisy real-valued statistic vector T, a function of sensitive data under DP, via the class of K-norm mechanisms with the goal of minimizing the noise added to achieve privacy. First, we introduce the sensitivity space of T, which extends the concepts of sensitivity polytope and sensitivity hull to the setting of arbitrary statistics T. We then propose a framework consisting of three methods for comparing the K-norm mechanisms: 1) a multivariate extension of stochastic dominance, 2) the entropy of the mechanism, and 3) the conditional variance given a direction, to identify the optimal K-norm mechanism. In all of these criteria, the optimal K-norm mechanism is generated by the convex hull of the sensitivity space. Using our methodology, we extend the objective perturbation and functional mechanisms and apply these tools to logistic and linear regression, allowing for private releases of statistical results. Via simulations and an application to a housing price dataset, we demonstrate that our proposed methodology offers a substantial improvement in utility for the same level of risk.

description: Double-lepton polarization asymmetries in the (B -> l^+ l^- gamma) decay are calculated using the most general, model independent form of the effective Hamiltonian including all possible forms of the interaction. The dependencies of the asymmetries on new Wilson coefficients are investigated. The detectability the averaged double-lepton polarization asymmetries at LHC is also discussed.

description: Diese Diplomarbeit präsentiert ein Erweiterungs-Framework für die leistungsfähige epistemische Modellierungs- und Analyse-Umgebung für Multiagentensysteme mit byzantinisch fehlerhaften Agenten, die 2019 von Kuznets el. al. publiziert wurde. Es erweitert die ursprünglich nur für asynchrone Agenten und asynchrone Kommunikation formulierte Umgebung in einer generischen Art und Weise, die die Formulierung und Kombination zusätzlicher Systemannahmen in modularer Form erlaubt. Unter den spezifischen Erweiterungen, die in der Arbeit enthalten sind, finden sich unter anderem zuverlässige Kommunikation, zeitbeschränkte Kommunikation, Multicasting, synchrone und lockstep-synchrone Agenten und sogar koordinierte Aktionen von Agenten, wie sie in der Modellierung und Analyse von fehlertoleranten verteilten Systemen oftmals anzutreffen sind. Für die zentralen Erweiterungen der synchronen und lockstep-synchronen Agenten werden auch elementare Eigenschaften des resultierenden Gesamtmodells abgeleitet, wie etwa lokale und globale Fehlererkennungsmöglichkeiten und die Existenz/Nichtexistenz eines “brain-in-the-vat”-Szenarios.
description: In this Master thesis, we provide an extension framework for the powerful epistemic reasoning framework for multi-agent systems with byzantine faulty agents published by Kuznets et. al. in 2019, which is currently restricted to asynchronous agents and asynchronous communication. We enrich the existing framework by a generic way to add extensions, which allow to encode and safely combine different system assumptions in a modular way. Among the particular extensions provided in this thesis are reliable communication, time-bounded communication, multicasting, synchronous and lock-step synchronous agents and even agents with coordinated actions, which are commonly used in modeling and analysis of fault-tolerant distributed systems. For the pivotal cases of synchronous and lock-step synchronous agents, we also analyze the basic properties of the resulting model, such as local and global fault detection abilities of the agents and the possibility of a “brain-in-a-vat” scenario.

description: The central claim of this paper is that the state-contingent approach provides the best way to think about all problems in the economics of uncertainty, including problems of consumer choice, the theory of the firm, and principal–agent relationships. This claim is illustrated by recent developments in, and applications of, the state-contingent approach.

description: This article focuses on the relationship between a measure of creativity and the human brain network for subjects in a brain connectome dataset obtained using a diffusion weighted magnetic resonance imaging (DWI) procedure. We identify brain regions and interconnections that have a significant effect on creativity. Brain networks are often expressed in terms of symmetric adjacency matrices, with row and column indices of the matrix representing the regions of interest (ROI), and a cell entry signifying the estimated number of fiber bundles connecting the corresponding row and column ROIs. Current statistical practices for regression analysis with the brain network as the predictor and the measure of creativity as the response typically vectorize the network predictor matrices prior to any analysis, thus failing to account for the important structural information in the network. This results in poor inferential and predictive performance in presence of small sample sizes. To answer the scientific questions discussed above, we develop a flexible Bayesian framework that avoids reshaping the network predictor matrix, draws inference on brain ROIs and interconnections significantly related to creativity, and enables accurate prediction of creativity from a brain network. A novel class of network shrinkage priors for the coefficient corresponding to the network predictor is proposed to achieve these goals simultaneously. The Bayesian framework allows characterization of uncertainty in the findings. Empirical results in simulation studies illustrate substantial inferential and predictive gains of the proposed framework in comparison with the ordinary high dimensional Bayesian shrinkage priors and penalized optimization schemes. Our framework yields new insights into the relationship of brain regions with creativity, also providing the uncertainty associated with the scientific findings.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We consider a harmonic oscillator (HO) with a time dependent frequency which undergoes two successive abrupt changes. By assumption, the HO starts in its fundamental state with frequency ω_{0}, then, at t = 0, its frequency suddenly increases to ω_{1} and, after a finite time interval τ, it comes back to its original value ω_{0}. Contrary to what one could naively think, this problem is a quite non-trivial one. Using algebraic methods we obtain its exact analytical solution and show that at any time t > 0 the HO is in a squeezed state. We compute explicitly the corresponding squeezing parameter (SP) relative to the initial state at an arbitrary instant and show that, surprisingly, it exhibits oscillations after the first frequency jump (from ω_{0} to ω_{1}), remaining constant after the second jump (from ω_{1} back to ω_{0}). We also compute the time evolution of the variance of a quadrature. Last, but not least, we calculate the vacuum (fundamental state) persistence probability amplitude of the HO, as well as its transition probability amplitude for any excited state.
