description: O objetivo deste ensaio é o de apresentar e discutir o desempenho recente da agricultura paulista em período de oito anos. Para tanto, utilizam-se as bases de dados do IEA, do ITESP e da FGV. Analisam-se variáveis de área plantada, preços e produção de produtos agrícola, rendimento físico do trabalhador rural em culturas específicas, preço da terra nua, número de famílias acampadas e inflação dos preços. As informações estão agrupadas por regiões do Estado de São Paulo. Dados sobre preços e produção foram utilizados para a construção de um índice de Laspeyres indicador de produção agrícola. Médias ponderadas de preços de produtos agrícolas foram empregadas na obtenção da variável dos termos de troca. Aqueles dois dados, mais área e rendimento físico do trabalho agrícola foram usados na construção de um índice Tornqvist de produtividade. Ao cabo, selecionam-se informações de um período de quatro a oito anos, dependendo da variável em foco, sobre a evolução, por região e para o Estado, de área plantada e área de mata natural, do índice de produção agrícola, do índice de produtividade agrícola, dos preços das terras rurais nuas de segunda, bem como do número de famílias acampadas na ocupação forçada de estabelecimentos rurais ou nas suas imediações. De posse destes dados, geram-se gráficos, diagramas de dispersão de pontos relacionando mudanças anuais de pares de variáveis e a análise da matriz de correlação entre as variáveis consideradas. -----------------------------------------------------The proposal of this essay is to argue about the recent performance of São Paulo agriculture during eight years. For that, we are using the databases of the Institute of Agriculture Economics (IEA), the Land Institute (ITESP) and the Getúlio Vargas Foundation (FGV). We intent to analyze the change of a set of agriculture and agrarian variables. Data on prices and production was used for the construction of a Laspeyres index for agricultural production. Weighed means of prices of agricultural products were used in the attainment of the exchange terms variable. Those two data, more area and physical return of the agricultural worker had been used in the construction of Tornqvist productivity index. To handle the information related to four to eight years, depending on the variable in focus, we selected variables like planted area, area of natural juggle, the index of agricultural production, the index of agricultural productivity, the prices of empty agricultural lands of second class, as well as the number of families involved with forced occupation of agricultural establishments. After that, we generate a set of graphs, dispersion diagram of points relating annual changes of pairs of variable and the analysis of the correlation matrix between the variable in question.

description: In this paper we show that different physiological states and pathological conditions may be characterized in terms of predictability of time series signals from the underlying biological system. In particular we consider systolic arterial pressure time series from healthy subjects and Chronic Heart Failure patients, undergoing paced respiration. We model time series by the regularized least squares approach and quantify predictability by the leave-one-out error. We find that the entrainment mechanism connected to paced breath, that renders the arterial blood pressure signal more regular, thus more predictable, is less effective in patients, and this effect correlates with the seriousness of the heart failure. The leave-one-out error separates controls from patients and, when all orders of nonlinearity are taken into account, alive patients from patients for which cardiac death occurred.
Designing and testing a prototypical landscape information interface for lay-people
Creators: name: Salter, Jonathan D.
Publisher: name: University of British Columbia
Year: 2009

description: Landscape management is increasingly moving towards managing for multiple values and involving the public in decision-making processes. To provide informed opinions about how they would like various aspects of the landscape to be managed, members of the public require information about the implications of given management actions. Ecological processes tend to occur over large spatial and temporal scales, and involve bothvisible and non-visible indicators of landscape condition. People have dif culty conceptualizing landscape processes at these large spatial and temporal scales. Conventional methods of communicating this type of landscape information in British Columbia have been criticized as being too technical and inaccessible for non-experts. Developing technologies, such as realistic landscape visualizations, have been heralded as possible solutions, because of their abilities to engage users and communicate effectively. Realistic landscape visualizations, however, emphasize the visual aspects of landscape change. This may exacerbate people's existing tendencies to evaluate landscape management based on what they see on the landscape. The purpose of this thesis was to design, build and evaluate a prototype landscape information interface to communicate spatial, temporal, visible and non-visible characteristics of the landscape to non-expert users. The resulting interface displayed landscape visualizations and indicator graphs in association with other contextual information. This interface was evaluated, using a questionnaire and an exploratory video analysis procedure, by investigating how non-expert subjects would use the interface to answer landscape related questions. Results of the evaluation suggest that subjects quickly understood the interface and the information it presented, and were able to combine the interface's representations to understand temporal and spatial aspects of the landscape. The subjects also demonstrated the ability to recognize relationships between the ecological indicators represented in the interface. The ndingsof the study suggest that such interfaces can be an effective means of communicating information about landscapes and the implications of management. Future directions are discussed, relating to the development and evaluation of landscape information displays.

description: The technology for autonomous vehicles is close to replacing human drivers by artificial systems endowed with high-level decision-making capabilities. In this regard, systems must learn about the usual vehicle's behavior to predict imminent difficulties before they happen. An autonomous agent should be capable of continuously interacting with multi-modal dynamic environments while learning unseen novel concepts. Such environments are not often available to train the agent on it, so the agent should have an understanding of its own capacities and limitations. This understanding is usually called self-awareness. This paper proposes a multi-modal self-awareness modeling of signals coming from different sources. This paper shows how different machine learning techniques can be used under a generic framework to learn single modality models by using Dynamic Bayesian Networks. In the presented case, a probabilistic switching model and a bank of generative adversarial networks are employed to model a vehicle's positional and visual information respectively. Our results include experiments performed on a real vehicle, highlighting the potentiality of the proposed approach at detecting abnormalities in real scenarios.

description: Let A,B,S be finite subsets of an abelian group G. Suppose that the restricted sumset C={a+b: a in A, b in B, and a-b not in S} is nonempty and some c in C can be written as a+b with a in A and b in B in at most m ways. We show that if G is torsion-free or elementary abelian then |C|\geq |A|+|B|-|S| -m. We also prove that |C|\geq |A|+|B|-2|S|-m if the torsion subgroup of G is cyclic. In the case S={0} this provides an advance on a conjecture of Lev.

description: The propagation of a chemical wave in a narrow, cone-shaped glass capillary was investigated. When a chemical wave propagates from the wider end to the narrower end, it slows, stops, and then disappears. A phenomenological model that considers the surface effect of the glass is proposed, and this model reproduces the experimental trends.

description: The same but different: That might describe two metrics. On the surface CLASSI may show two metrics are locally equivalent, but buried beneath one may be a wealth of further structure. This was beautifully described in a paper by M.A.H. MacCallum in 1998. Here I will illustrate the effect with two flat metrics -- one describing ordinary Minkowski spacetime and the other describing a three-parameter family of Gal'tsov-Letelier-Tod spacetimes. I will dig out the beautiful hidden classical singularity structure of the latter (a structure first noticed by Tod in 1994) and then show how quantum considerations can illuminate the riches. I will then discuss how quantum structure can help us understand classical singularities and metric parameters in a variety of exact solutions mined from the Exact Solutions book.

description: A suspended layer made up of ferromagnetically ordered spins could be created between two mono/multilayer graphene through intercalation. Stability and electronic structure studies show that, when fluorine molecules are intercalated between two mono/multilayer graphene, their bonds get stretched enough ($\sim$ 1.9$-$2.0 Å) to weaken their molecular singlet eigenstate. Geometrically, these stretched molecules form a pseudoatomized fluorine layer by maintaining a van der Waals separation of $\sim$ 2.6 Å from the adjacent carbon layers. As there is a significant charge transfer from the adjacent carbon layers to the fluorine layers, a mixture of triplet and doublet states stabilize to induce local spin-moments at each fluorine sites and in turn form a suspended 2D spin lattice. The spins of this lattice align ferromagnetically with nearest neighbour coupling strength as large as $\sim$ 100 meV. Our finite temperature \textit {ab initio} molecular dynamics study reveals that the intercalated system can be stabilized up to a temperature of 100 K with an average magnetic moment of $\sim$ 0.6 $μ_{B}$/F. However, if the graphene layers can be held fixed, the room temperature stability of such a system is feasible.

description: In this paper we show that during the retrieval process in a binary symmetric Hebb neural network, spatial localized states can be observed when the connectivity of the network is distance-dependent and when a constraint on the activity of the network is imposed, which forces different levels of activity in the retrieval and learning states. This asymmetry in the activity during the retrieval and learning is found to be sufficient condition in order to observe spatial localized states. The result is confirmed analytically and by simulation.

description: O carvão vegetal é uma importante fonte de energia para a produção de ferro-gusa no Estado do Pará. O aumento da produção da siderurgia no Estado vem exigindo um maior consumo deste insumo provocando um déficit ambiental, haja vista não está havendo o retorno necessário e exigido dos recursos florestais utilizados na produção desse produto. Em virtude de suas características produtivas, surge como uma alternativa de incorporação de trabalho com baixa qualificação, aspecto típico de localidades amazônicas. Entretanto, para que seja uma alternativa eficaz é importante que haja uma racionalidade ao longo da cadeia produtiva a partir da utilização de tecnologias que reduzam os impactos negativos sobre o meio ambiente. Com o intuito de verificar quais municípios são mais especializados na atividade utilizou-se da metodologia do ICN a partir do valor bruto da produção de carvão, em virtude do elevado grau de informalidade da força de trabalho ligado à essa atividade. Os resultados refletem o cenário atual das regiões envolvidas na produção de carvão ao mesmo tempo em que permitiram identificar a postura adotada pelo setor público no que tange a busca da sustentabilidade da atividade.
Local Commutativity and Causality in Interacting PP-wave String Field Theory

description: In this paper, we extend our previous study of causality and local commutativity of string fields in the pp-wave lightcone string field theory to include interaction. Contrary to the flat space case result of Lowe, Polchinski, Susskind, Thorlacius and Uglum, we found that the pp-wave interaction does not affect the local commutativity condition. Our results show that the pp-wave lightcone string field theory is not continuously connected with the flat space one. We also discuss the relation between the condition of local commutativity and causality. While the two notions are closely related in a point particle theory, their relation is less clear in string theory. We suggest that string local commutativity may be relevant for an operational defintion of causality using strings as probes.

The analysis includes the $π^0$ mass, the effective $π^0$-quark coupling and the pion-to-vacuum hadronic form factors, both at zero and finite temperature. Numerical results are compared with previous calculations carried out within the local NJL model, when available. The validity of chiral relations and the features of deconfinement and chiral symmetry restoration transitions are discussed.

description: O presente trabalho tem como objetivo apresentar o estudo comparativo de retorno de investimentos em três áreas de terras arrendadas, de diferentes tamanhos, localizadas na região noroeste do Paraná, mais especificamente no município de Umuarama. Nesta região de solo arenoso, denominado Arenito Caiuá, tem-se presenciado, um crescimento significativo no setor de agronegócio. E, este vem se destacando em todo Brasil, pela alta competitividade internacional, devido aos baixos custos de produção, à crescente demanda e ao território disponível. O trabalho identifica, aos investidores, o valor da aplicação inicial e conseqüentemente o valor do retorno, após o período da colheita. Foi considerada uma previsão inicial de cinco anos, desprezando o armazenamento dos produtos para posterior venda. Na elaboração do trabalho foram realizadas pesquisas de mercado, com o intuito de identificar valores de insumos, arrendamento, aluguel de máquinas e preços médios praticados. Também foram utilizadas planilhas eletrônicas, com o uso do software EXCEL®, para apurar e calcular os indicadores TIR, VPL e Payback. Os levantamentos e comparações poderão subsidiar os investidores na aplicação de seu capital, especialmente na cultura da soja e milho safrinha. Finalmente, o trabalho indica o retorno do capital aplicado e concluí que quanto maior a área, maior será a rentabilidade do projeto e menor será o custo operacional.-----------------------------------------------The work presents a study of return on investment in three areas of land of different sizes, in Umuarama, norwest of Paraná. In this region, with arenaceous soil, called Arenito Caiuá, is having a significant growth in the agribusiness. This economic sector is very important in Brasil by high productivity e competiveness in international context. Low costs, increase demand and available territory are vantages for the country. The work identifies for the investors the inicial values and the return on investment after harvest. An initial forecast was considered five years. In the elaboration of this work, market researches had been for to identify the price of the inputs and the price of products (corn and soybean). Were used the ExcelR to calculate the IRR, NPV and Payback. The work indicates the return of the applied capital and concluded that how much bigger the area, greater will be the yield of the project and lewer the operational cost.

description: The effect of an oscillating electric field generated from music on yeast vacuolar proton-ATPase (V-ATPase) activity in its native environment is reported. An oscillating electric field is generated by electrodes that are immersed into a dispersion of yeast vacuolar membrane vesicles natively hosting a high concentration of active V-ATPase. The substantial difference in the ATP hydrolysing activity of V-ATPase under the most stimulating and inhibiting music is unprecedented. Since the topic, i.e. an effect of music on biomolecules, is very attractive for non-scientific, esoteric mystification, we provide a rational explanation for the observed new phenomenon. Good correlation is found between changes in the specific activity of the enzyme and the combined intensity of certain frequency bands of the Fourier spectra of the music clips. Most prominent identified frequencies are harmonically related to each other and to the estimated rotation rate of the enzyme. These results lead to the conclusion that the oscillating electric field interferes with periodic trans-membrane charge motions in the working enzyme.

Das Buch verfolgt die Geschichte der Bibliothek, die sowohl der Wissenschaft als auch dem breiten Publikum zu dienen hat, von den Anfängen bis heute. Die bauliche Ausgestaltung und Entwicklung des Hauses sind ebenso Thema wie die Rekrutierung und Ausbildung des Personals, die Probleme der Katalogisierung und Computerisierung, das Wachstum der zahlreichen Sammlungen und die Veränderungen der finanziellen Rahmenbedingungen. Dabei wird auch klar, wie stark sich die Bibliotheken heute im Umbruch befinden und mit welchen gewaltigen Herausforderungen sie sich konfrontiert sehen. Aus den Texten der fünf Autorinnen und Autoren ist ein reichhaltig illustriertes und sorgfältig gestaltetes Buch entstanden.

description: The globular cluster M15 was observed on three occasions with the High Resolution Camera on board Chandra in 2001 in order to investigate the X-ray source population in the cluster centre. After subtraction of the two bright central sources, four faint sources were identified within 50 arcsec of the core. One of these sources is probably the planetary nebula, K648, making this the first positive detection of X-rays from a planetary nebula inside a globular cluster. Another two are identified with UV variables (one previously known), which we suggest are cataclysmic variables (CVs). The nature of the fourth source is more difficult to ascertain, and we discuss whether it is possibly a quiescent soft X-ray transient (qSXT) or also a CV.

Benchmarking the Canadian value-added wood products sector : competitive factors that contribute to its success
Creators: name: DeLong, Deborah Louise
Publisher: name: University of British Columbia
Year: 2009

description: In recent years, there has been considerable interest in the secondary wood manufacturing sector across Canada. Strengthening and facilitating the secondary wood manufacturing or value-added sector is seen as the next step to creating a more sustainable economy across Canada. This research considered all secondary wood manufacturers across Canada and has provided standardized information for the entire sector as a benchmark. In order to evaluate the competitive position of the Canadian secondary wood manufacturers, two steps were undertaken. First, factors that have determined success in other sectors were identified. Secondly, the sector's current business environments and their emphasis on the factors that contribute to success were evaluated. The majority of businesses in this sector are small to medium enterprises (SMEs) and have common concerns that effect SMEs. Problems obtaining financing for expansion, market research, expanding to new markets, and upgrading employees' skills are examples. There is also opportunity for increasing efficiencies through lean manufacturing and optimizing supply chains. These types of initiatives will require education and training. Logistic regression analysis found that being a member of an industry association greatly increased the probability of a business being profitable. Industry associations are likely an effective conduit for the required training and education.

description: Entre os anos 2001/2007, a agricultura nacional cresceu a taxas extraordinárias, superiores às dos outros setores da economia. Este excelente desempenho da agricultura nacional ocorreu sem que existisse um aparato de políticas públicas para fomentá-lo. Desta forma, o desempenho da agricultura favoreceu a atuação de grupos de pressão sobre o marco regulatório dos agrotóxicos, no qual segmentos do setor agrícola e entidades representativas de empresas produtoras de agrotóxicos têm procurado reduzir as exigências para o registro de novos produtos, sob a alegação de que isto reduziria os preços dos agrotóxicos ao produtor rural, melhorando a competitividade da agricultura nacional, e ainda promoveria a redução do grau de concentração do mercado brasileiro de agrotóxicos. Neste contexto, o objetivo deste trabalho é traçar um histórico da evolução recente da indústria de agrotóxicos no Brasil, de 2001 a 2007, buscando sugerir e articular, ainda que brevemente, as relações existentes entre a esfera econômica e a legal na evolução recente dessa indústria no Brasil. ----------------------------------------------Between the years 2001/2007, brazilian agriculture has grown in extraordinary levels, greater than the others economic sectors. This excellent performance of the national agriculture occurred without a grandeur of public policies aiming to foment it. From this, the agriculture’s performance supports pressure groups over the pesticides’ regulatory mark, in which agriculture’s sector entities and pesticides’ industry representative entities have aimed to reduce the exigencies to register new products, under the allegation that the pesticides’ price should fall, improving brazilian agricultural competitiveness and also promoting the reduction in the pesticide market concentration. In this context, the objective of this paper is to trace the recent history of the pesticide industry in Brazil, from 2001 to 2007, seeking to suggest and to articulate, briefly, the economic-legal nexus in the recent evolution of this industry in Brazil.

description: We report the results of a photometric search for giant stars associated with the cores of four high velocity clouds (HVCs) -- two of which are compact HVCs -- using the Las Campanas Du Pont 2.5 meter and Cerro Tololo Blanco 4 meter telescopes in combination with a system of filters (Washington M, T_2 + DDO51) useful for identifying low surface gravity, evolved stars. Identical observations of nearby control fields provide a measure of the ``giant star'' background. Our data reach M_0=22 for three of the HVCs and M_0=21.25 for the fourth, depths that allow the detection of any giant stars within 600 kpc. Although we identify a number of faint late-type giant star candidates, we find neither a coherent red giant branch structure nor a clear excess of giant candidate counts in any HVC. This indicates that the giant candidates are probably not related to the HVCs and are more likely to be either random Milky Way giant stars or one of several classes of potential survey contaminants. Echelle spectroscopy of the brightest giant candidates in one HVC and its control field reveal radial velocities representative of the canonical Galactic stellar populations. In addition to these null results, no evidence of any young HVC stellar populations -- represented by blue main sequence stars -- is found, a result consistent with previous searches. Our methodology, specifically designed to find faint diffuse stellar populations, places the tightest upper limit yet on the total stellar mass of HVCs of a few 10^5 M_{\sun}.

A Physiological Model to Quantify Impacts of Climate Change Variables on Cocoa Productivity

description: Climate change has the potential to alter cocoa production through, for example, changes in rainfall patterns (more intense droughts and/or more intense wet seasons), higher temperatures and increased carbon dioxide concentrations. A crop modelling approach allows prediction of yield changes in relation to climate events and quantification of interventions designed to ameliorate such changes (e.g. use of overhead shade or planting of different cocoa varieties more adapted to climate change). 
A physiological model is described that is parameterised using experimental data collected under controlled environment conditions. The model is compartmentalised into interacting modules that include assimilation of carbohydrates through canopy photosynthesis, respiration, partitioning of assimilates between vegetative and reproductive growth, partitioning of assimilates within the pod and the dynamics of pod-setting and wilting. Canopy photosynthesis is calculated from the parameters of photosynthetic light response curves of genotypes, specified by the user, and the properties of the canopy (leaf area index and light attenuation through the canopy, quantified as the extinction coefficient). Environmental parameters that can be modulated in the model include carbon dioxide concentration, soil water content, air temperature, vapour pressure deficit and solar radiation. These parameters then influence the outputs of the different modules, for example temperature impacts on photosynthetic rate and also on the amount of cherelle wilt.
A range of model simulations are presented on the impacts of elevated CO2 concentration, increases in temperature, water deficit and their interaction on productivity and yield. The potential impact of interventions such as changing variety and use of overhead shade in ameliorating the effects of climate change is also discussed.

description: Population-scale drug prescription data linked with adverse drug reaction (ADR) data supports the fitting of models large enough to detect drug use and ADR patterns that are not detectable using traditional methods on smaller datasets. However, detecting ADR patterns in large datasets requires tools for scalable data processing, machine learning for data analysis, and interactive visualization. To our knowledge no existing pharmacoepidemiology tool supports all three requirements. We have therefore created a tool for interactive exploration of patterns in prescription datasets with millions of samples. We use Spark to preprocess the data for machine learning and for analyses using SQL queries. We have implemented models in Keras and the scikit-learn framework. The model results are visualized and interpreted using live Python coding in Jupyter. We apply our tool to explore a 384 million prescription data set from the Norwegian Prescription Database combined with a 62 million prescriptions for elders that were hospitalized. We preprocess the data in two minutes, train models in seconds, and plot the results in milliseconds. Our results show the power of combining computational power, short computation times, and ease of use for analysis of population scale pharmacoepidemiology datasets. The code is open source and available at: https://github.com/uit-hdl/norpd_prescription_analyses

description: Searching for strangelets in cosmic rays may be the best way to test the possible stability of strange quark matter. I review calculations of the astrophysical strangelet flux in the GV--TV rigidity range, which will be investigated from the Alpha Magnetic Spectrometer (AMS-02) on the International Space Station, and discuss the merits of strangelets as ultra-high energy cosmic rays at EeV--ZeV energies, beyond the Greisen-Zatsepin-Kuzmin cutoff. I also address some ``counter-arguments'' sometimes raised against the possibility of stable strangelets. It will be argued that stability of strange quark matter remains a viable possibility, which must be tested by experiments.

Parity, Charge Conjugation and SU(3) Constraints on Threshold Enhancement in $J/ψ$ decays into $γp\bar p$ and $K p \barΛ$

description: We study the threshold enhancement effects of baryon-anti-baryon systems in $J/ψ$ decays at BES using parity $P$, charge conjugation $C$, and flavor SU(3) symmetries. The $P$ and $C$ symmetries restrict the $p\bar p$ in $J/ψ\to γp\bar p$ to be in a state with $C=+1$, while the $p\bar p$ in $J/ψ\to π^0 p\bar p$ to be with $C=-1$. Combining the $C$ and $P$ symmetries with flavor SU(3) symmetry, i.e. the CPS symmetry, we find that the $Λ\bar p$ system cannot be in $0^+$ and $0^-$ states in $J/ψ\to K^+ Λ\bar p$. We provide a consistent explanation of observation and non-observation of near threshold enhancements in $J/ψ\to K^+ Λ\bar p$ and $J/ψ\to π^0 p \bar p$, respectively. We also find that near baryon pair threshold enhancement can happen in several channels for $J/ψ$ decays and can be several times larger than that observed in $J/ψ\to K^+ Λ\bar p$ in some channels.
