description: In this paper we develop an adaptive transform-domain technique based on rational function systems. It is of general importance in several areas of signal theory, including filter design, transfer function approximation, system identification, control theory etc. The construction of the proposed method is discussed in the framework of a general mathematical model called variable projection. First we generalize this method by adding dimension type free parameters. Then we deal with the optimization problem of the free parameters. To this order, based on the well-known particle swarm optimization (PSO) algorithm, we develop the multi-dimensional hyperbolic PSO algorithm. It is designed especially for the rational transforms in question. As a result, the system along with its dimension is dynamically optimized during the process. The main motivation was to increase the adaptivity while keeping the computational complexity manageable. We note that the proposed method is of general nature. As a case study the problem of electrocardiogram (ECG) signal compression is discussed. By means of comparison tests performed on the PhysioNet MIT-BIH Arrhythmia database we demonstrate that our method outperforms other transformation techniques.

description: Morphological analysis of longitudinal MR images plays a key role in monitoring disease progression for prostate cancer patients, who are placed under an active surveillance program. In this paper, we describe a learning-based image registration algorithm to quantify changes on regions of interest between a pair of images from the same patient, acquired at two different time points. Combining intensity-based similarity and gland segmentation as weak supervision, the population-data-trained registration networks significantly lowered the target registration errors (TREs) on holdout patient data, compared with those before registration and those from an iterative registration algorithm. Furthermore, this work provides a quantitative analysis on several longitudinal-data-sampling strategies and, in turn, we propose a novel regularisation method based on maximum mean discrepancy, between differently-sampled training image pairs. Based on 216 3D MR images from 86 patients, we report a mean TRE of 5.6 mm and show statistically significant differences between the different training data sampling strategies.

description: Objective: Cortical dynamics is driven by cortico-cortical connectivity and it characterizes cortical morphological features. These brain surface features complement volumetric changes and may offer improved understanding of disease pathophysiology. Hence, present study aims to investigate surface features; cortical thickness (CT) and gyrification index (GI) in Parkinson’s disease (PD) patients of normal cognition (PD-CN), cognitively impaired patients with PD (PD-CI) in comparison with cognitively normal healthy controls (HC) to better elucidate cognition linked features in PD. Method: Anatomical MRI (3DT1) was carried out in 30 HC (56.53 ± 8.42 years), 30 PD-CN (58.8 ± 6.07 years), and 30 PD-CI (60.3 ± 6.43 years) subjects. Whole brain ROI based parcellation using Desikan-Killiany (DK-40) atlas followed by regional CT and GI differentiation [with ‘age’ and ‘total intracranial volume’ (TIV) correction], multiple linear regression (with ‘age’, ‘TIV’, and ‘education’ correction) with clinical variables, ROC analysis, and CT-GI correlation across the groups was used for data analysis. Results: Widespread cortical thinning with regional GI reduction was evident in PD-CI with respect to other two groups (HC and PD-CN), and with absence of such alterations in PD-CN compared to HC. Frontal, parietal, and temporal CT/GI significantly correlated with cognition and presented classification abilities for cognitive state in PD. Mean regional CT and GI were found negatively correlated across groups with heterogeneous regions. Conclusion: Fronto-parietal and temporal regions suffer cognition associated cortical thinning and GI reduction. CT may serve better discriminator properties and may be more consistent than GI in studying cognition in PD. Heterogeneous surface dynamics across the groups may signify neuro-developmental alterations in PD.

description: Kazakhstan is now widely regarded as a key player on world agricultural markets, with considerable export potential in the wheat, beef and dairy sectors. Based on unique farm-level data covering all production systems currently relevant, we offer new insights into the constraints that hamper further economic growth and provide an assessment of the government’s agricultural development strategy. A frequently mentioned bottleneck is agriculture’s lacking access to finance. But most farm managers in the farm survey doubt that agricultural investments deliver a sufficiently reliable return required for credit funding and thus do not take loans. Despite the vast land resources, a lack of land supply is now the most cited constraint to farm expansion in the highly regulated land market of the northern grain region. Another set of constraints in wheat production is related to the market power of elevators, the vagaries of trading over long distances in an underdeveloped rail and seaport infrastructure, and the intervention activities of state agencies. In the cattle sector, there are significant problems in year-round fodder supply. The value chains for beef and dairy are bifurcated into an import-dependent chain for industrially processed products serving urban consumers, and a local chain of raw products serving rural consumers and urban bazaars. Recent modernisation strategies of the government tend to focus on the provision of subsidised capital, while they underestimate the knowledge and incentive problems inherent to a state-guided management of sector development. The government should rather focus on providing impartial, reliable and high-quality public services to the sector, making sure that the weakest links in food chain development are identified and private entrepreneurs are provided with the necessary incentives to strengthen them. Our evidence suggests that a bundle of measures improving the local institutional environment of agriculture is more important than massive state funding of certain production lines.

description: The objective of this paper is to determine the long-term effects of rural credit on agricultural production, trade and competitiveness (through prices) in the Brazilian regions. The simulations were performed applying the General Equilibrium Analysis Project of the Brazilian Economy (PAEG). The results suggest that the rural credit policy represents an important stimulus to the entire Brazilian agribusiness chains given the positive impacts on agriculture production, exports, and expansion of industries with strong linkages with the agricultural sector. Also, the policy is associated with agricultural competitiveness gains (through prices) in foreign markets.

description: To describe Embrapa role in the development of the agribusiness it was important to characterize the economic environment that prevailed in the sixties and beginning of the seventies to show that the creation and development of Embrapa was a conscious decision of the federal government to bolster agricultural production and exports to solve food supply deficiencies and balance of pay-ment problems. The mandate of Embrapa was very specific and clear: to generate technology for the adoption of the farmers. The paper stresses the importance of the universities, state research and the connections with international advanced research centers. Brazil developed an important agricul-tural research complex to deal with problem of tropical environment. This complex handles tech-nologies to the farmers and is fed by their problems. Presently is also working with farmer problems of Africa, Asia and Latin America countries. The growth of productivity at the farmer level explains much of the success of the agribusiness, and it is one of the greatest successes of agrarian sciences, of farmer ingenuity, macroeconomic stability, and of the institutions in charge of the development of agriculture. Side by side with great success of the agribusiness there are millions of small pro-ducers left at the margin of modern agriculture. To solve their problem is one of the most important challenges of Brazilian society. The text also reviews Brazilian agricultural and agrarian reform policies.

description: This paper studies the security of a secure communication scheme based on two discrete-time intermittently-chaotic systems synchronized via a common random driving signal. Some security defects of the scheme are revealed: 1) the key space can be remarkably reduced; 2) the decryption is insensitive to the mismatch of the secret key; 3) the key-generation process is insecure against known/chosen-plaintext attacks. The first two defects mean that the scheme is not secure enough against brute-force attacks, and the third one means that an attacker can easily break the cryptosystem by approximately estimating the secret key once he has a chance to access a fragment of the generated keystream. Yet it remains to be clarified if intermittent chaos could be used for designing secure chaotic cryptosystems.

description: There had been no discernable progress in the WTO's Doha Round for more than two years. Major trading nations have been actively seeking progress on trade liberalization in other venues such as preferential trade agreements. The WTO seemed to many to be slipping into irrelevance as a force for trade liberalization. Part of the difficulty was that successful conclusions of rounds require all of the round's agenda items to be dealt with as a single undertaking. Faced with another failure to conclude the round as a single undertaking, a new tactic was tried at the WTO Ministerial in Bali in December 2013. A subset of agenda items where agreement could be reached was announced at the Ministerial. It was presented as a major accomplishment for the WTO. This paper examines the Bali agreement to determine if it brings sufficient progress to garner the WTO the renewed prestige that it seeks.

By means of an approximated model for the binary mixture and of a perturbative approach we derive close formulas for the free energy of the system and for the surface tension of the interface. Our results show a remarkable non-monotonous dependence of the surface tension on the peak of the density of the suspended phase. Our results also predict the local value of the surface tension in the case in which the density of the suspended phase is not homogeneous along the interface.

description: El caracter comunal del aqua de riego have que su asignacion eficiente no se produzca a traves del meracdo sino mediante otro tipo de instituciones mas especificas. Estas logran su eficacia integrando la negociacion y la cooperacion entre los agentes implicados y dando cabida a sus multiples objectivos y diversidad de intereses. Por tanto, el paradigma neoclasico de los mercados de competencia perfecta no asegura las garantias de fiabilidad y itulidad deseables para el analisis economico del aqua de riego. Por ello, se aboga por otro marco teorico alternativo que, resolviendo controversias, sea plenamente aceptado y represente mejor los verdaderos mecanismos que determinan la asignacion eficiente del recurso. As a result of the communal character of irrigation water, the efficient allocation of water does not occur through the market, but through the effective operation of other specific institutions. These achieve their efficiency by integrating the cooperation and negotiation of the agents involved, allowing the match between their multiple objectives and interests. Therefore, the neoclassical paradigm of perfectly competitive markets does not ensure the reliability and utility guarantees desirable for economic analysis of irrigation water. Thus, there is a need of an alternative theoretical framework that, resolving disputes, can be fully accepted and can better represent the real mechanisms that determine the efficient allocation of this resource.
Female breast cancer survivors : perceived stressors and coping strategies during treatment
Creators: name: Musgrove, Tamiko Elizabeth
Publisher: name: University of British Columbia

description: Breast cancer is a major health concern for Canadian women. Women diagnosed with breast cancer undergo breast cancer treatment, and must deal with the stressors that treatment presents. The present study drew on Lazarus and Folkman's (1984) transactional model to ensure that the meanings of "stress" and "coping" were based on each woman's appraisals. For the purpose of the study, treatment was defined as at least one breast surgery (i.e., lumpectomy or mastectomy), and at least one form of adjuvant therapy (i.e., chemotherapy, radiation therapy, or hormone therapy). Ten Caucasian women, aged 47 to 74, took place in an audio-taped, semi-structured interview. On average, the interviews were one hour in length. The research question that guided each interview was: "At each stage of breast cancer treatment what was the most salient stressor, and how did the women cope with that stressor?" The interviews were transcribed and analyzed using the constant comparative method (Strauss & Corbin, 1990). Data analysis also included open coding and memo writing. The findings revealed that, for these women, breast cancer treatment presented a number of stressors, and the women responded by mobilizing predominantly active coping strategies. In addition to a lack of concrete links between stressors and coping strategies, a clear progression in the coping strategies of the women throughout treatment was not apparent. However, the themes indicate that the appraisal processes of the women during treatment were complex and dynamic. Seven themes emerged from the analysis that represented the salient stressors and coping strategies during treatment. The themes included: (a) Dimensions of Time, (b) Physical Effects of Treatment, (c) Being Prepared, (d) Emotionality During Treatment, (e) Support from Others, (f) Thoughts to Self, and (g) Doing for Self. What each woman appraised as a stressor depended on her unique interaction with her environment, and the coping strategies she mobilized depended on her view of the world, her coping resources, and her context. An understanding that each woman's appraisal process (i.e., what are stressors) is unique, and that multiple elements contribute to coping is valuable to clinicians working with women undergoing breast cancer treatment.

Se analiza la region catalana del Priorat, especificamente las innovaciones empresariales en el sector vitivinicola registradas durante la decada de los noventa. Los resultados de la investigacion verifican la posibilidad empirica de que ambas formas de capital social, articuladas eficazmente, actuen conjuntamente para promover la innovacion a nivel local y regional. The paper presents the results of a case study that aims to investigate whether the presence of both bridging and bonding social capital, acting together, can stimulate entrepreneurial innovation at a regional level, as well as the manner in which both types of social capital interact to reach this result. This will be done through the analysis of the Catalan region of Priorat, and more specifically the entrepreneurial innovations of the region's wine sector experienced in the decade of the '90s. The research findings confirm the empirical possibility that both forms of social capital, if articulated effectively, can work together to promote local and regional innovation.

description: Se describe la situacion de las poblaciones de peces del rio Louzara a partir del inventario demografico de la especia principal, la trucha comun, y a partir del analisis de la presion pesquera y del habitat (calidad del agua, fisiografia del cauce y vegetacion de la cuenca). Se han realizado nueve estaciones de muestreo por pesca electrica, registrandose la longitud furcal, peso, edad y crecimiento de las escamas sobre los ejemplares capturados. Los resultados informan de un habitat de gran calidad para la trucha, muy levemente alterado por la accion humana pero con baja biomasa poblacional (11,5 kg/ha) y fuertes desequilibrios entre edades. Se concluye que la elevada presion de los pescadores, debida a un regimen de aprovechamiento libre, esta en el origen de los desequilibrios demograficos detectados. Se propenen las medidas de gestion a aplicar para favorecer la regeneracion natural de las poblaciones de trucha. The situation of the fish population in the Louzara River was described from the study of the demographic characteristics of the main species, brown trout, and the environment analysis (quality of the water, physiography of the river bed, vegetation of the basin and fishing effort). A fish inventory was carried out in nine sampling points by means of electric fishing. Length, weight, age and growth were measured in individuals captured. The strong influence of the overfishing pressure on a free fishing area in a slightly altered environment was shown (low stocks, 11.5 kg/ha, and unbalanced ages). Finally, management rules were proposed in order to improve the populations of brown trout.
Tracing cosmic evolution with clusters of galaxies

Year: 2004

description: The most successful cosmological models to date envision structure formation as a hierarchical process in which gravity is constantly drawing lumps of matter together to form increasingly larger structures. Clusters of galaxies currently sit atop this hierarchy as the largest objects that have had time to collapse under the influence of their own gravity. Thus, their appearance on the cosmic scene is also relatively recent. Two features of clusters make them uniquely useful tracers of cosmic evolution. First, clusters are the biggest things whose masses we can reliably measure because they are the largest objects to have undergone gravitational relaxation and entered into virial equilibrium. Mass measurements of nearby clusters can therefore be used to determine the amount of structure in the universe on scales of 10^14 to 10^15 solar masses, and comparisons of the present-day cluster mass distribution with the mass distribution at earlier times can be used to measure the rate of structure formation, placing important constraints on cosmological models. Second, clusters are essentially ``closed boxes'' that retain all their gaseous matter, despite the enormous energy input associated with supernovae and active galactic nuclei, because the gravitational potential wells of clusters are so deep. The baryonic component of clusters therefore contains a wealth of information about the processes associated with galaxy formation, including the efficiency with which baryons are converted into stars and the effects of the resulting feedback processes on galaxy formation.

description: Recently sparse regression codes / sparse superposition codes have been proposed and it has been shown that those codes asymptotically (that is for large block size) achieve the performance limits of information theory. The codes are formed from Gaussian random sequences that are arranged in the columns of a large matrix, and groups of data bits are used to identify which column-vectors are chosen for superimposed transmission over a Gaussian channel. Hence the coding process can be written as a matrix-vector multiplication, with the matrix containing the Gaussian code-sequences and the data vector containing only few non-zero components (that are determined by the data bits) that identify which of the code-column vectors are used to form a codeword. Since the vector is sparse, the decoding can be understood as a sparse recovery problem that has been recently and intensively studied in the field of compressed sensing. Some of the best sparse recovery algorithms are based on approximate message passing (AMP) which is also a good candidate decoder for sparse regression codes (SPARCs). A particularity of the SPARCs is that for good decoding by AMP not only values of constant amplitude are used to identify which of the column vectors are chosen but rather a sophisticated power allocation scheme that determines the scaling factors is required, and only then theoretical limits can be achieved. The first goal of the thesis is to understand the construction, encoding, power allocation, and decoding of SPARCs for the unconstrained Gaussian channel from the recent literature. In a second step, the codes shall be implemented (mostly in Matlab) and simulations shall be conducted to verify performance known from the literature. In terms of novelty, several interesting topics occur: one is to investigate SPARCs for various block sizes to understand how those codes would work in practical applications with strong delay constraints , that naturally limit the block size. Another interesting question is if it makes sense to concatenate sparse regression codes with classical binary channel codes and, if possible, to apply iterative decoding between the component codes.

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.

A Time Domain Approach for the Exponential Stability of a Nondissipative Linearized Compressible Flow-Structure PDE System

description: We consider a linearized compressible flow structure interaction (FSI) PDE model with a view of analyzing the stability properties of both the compressible flow and plate solution components. In our earlier work, we gave an answer in the affirmative to question of uniform stability for finite energy solutions of said compressible flow-structure system, by means of a ``frequency domain'' approach. However, the frequency domain method of proof in that work is not ``robust'' (insofar as we can see), when one wishes to study longtime behavior of solutions of compressible flow-structure PDE models which track the appearance of the ambient state onto the boundary interface (i.e., $κ=1$ in flow PDE component (2)). Nor is a frequency domain approach in this earlier work availing when one wishes to consider the dynamics, in long time, of solutions to physically relevant nonlinear versions of the compressible flow-structure PDE system under present consideration (e.g., the Navier-Stokes nonlinearity in the PDE flow component, or a nonlinearity of Berger/Von Karman type in the plate equation). Accordingly, in the present work, we operate in the time domain by way of obtaining the necessary energy estimates which culminate in an alternative proof for the uniform stability of finite energy compressible flow-structure solutions. This novel time domain proof will be used in our forthcoming paper which addresses the existence of compact global attractors for the corresponding nonlinear coupled system in which the material derivative -- which incorporates the aforesaid ambient state -- of the interaction surface will be taken into account.
A Pieri-type formula for the K-theory of a flag manifold

description: We derive explicit Pieri-type multiplication formulas in the Grothendieck ring of a flag variety. These expand the product of an arbitrary Schubert class and a special Schubert class in the basis of Schubert classes. These special Schubert classes are indexed by a cycle which has either the form (k-p+1,k-p+2,...,k+1) or the form (k+p,k+p-1,...,k), and are pulled back from a Grassmannian projection. Our formulas are in terms of certain labeled chains in the k-Bruhat order on the symmetric group and are combinatorial in that they involve no cancellations. We also show that the multiplicities in the Pieri formula are naturally certain binomial coefficients.

description: New quantum private database (with N elements) query protocols are presented and analyzed. Protocols preserve O(logN) communication complexity of known protocols for the same task, but achieve several significant improvements in security, especially concerning user privacy. For example, the randomized form of our protocol has a cheat-sensitive property - it allows the user to detect a dishonest database with a nonzero probability, while the phase-encoded private query protocols for the same task do not have such a property. Moreover, when the database performs the computational basis measurement, a particular projective measurement which can cause a significant loss of user privacy in the previous private query protocols with O(logN) communication complexity, at most half of the user privacy could leak to such a database in our protocol, while in the QPQ protocol, the entire user privacy could leak out. In addition, it is proved here that for large N, the user could detect a cheating via the computational basis measurement, with a probability close to 1/2 using O(\sqrt{N}) special queries. Finally, it is shown here, for both forms of our protocol, basic and randomized, how a dishonest database has to act in case it could not learn user's queries.
On the Nature of the Heat Source for Damped Lya Systems

description: We investigate the heat source of the neutral gas comprising DLAs. Unlike the Lya forest, where the extragalactic background radiation field ionizes and heats the gas, we find that grain photoelectric heating by the FUV background is not sufficient to balance the C II 158um cooling rate inferred from DLAs. In these systems, a local energy source is required. We show that in the case of the z=1.919 DLA toward Q2206-19, the local source is FUV emission from the associated galaxy found by Moller et al (2002): the mean intensity inferred from photometry is in good agreement with the intensity Jnu required to explain the cooling rate. The FUV mean intensity predicted for a cold neutral medium (CNM) model, Jnu=(1.7+2.7-1.0)x10^(-18) cgs (95% c.l.), is the largest expected from our CII* study of 45 DLAs. This may explain why this is the only confirmed DLA yet detected in emission at z>1.9. We argue that in most DLAs with detected CII* absorption, Jnu is between 10^{-19} and 10^{-18} and heats the gas which is a CNM. By contrast, in most DLAs with upper limits on CII* absorption the gas is a warm neutral medium (WNM). Surprisingly, the upper limits are compatible with the same range of Jnu values suggesting the majority of DLAs are heated by radiation fields generated by a limited range of star formation rates per unit H I area, between 10^{-3} and 10^{-2} Msol/kpc^2. We also show that CII* absorption is unlikely to arise in gas that is ionized.
