The menstrual cycle, ovulatory, and hormonal effects of an 8-week abruptly increasing running program in recreationally active women
Creators: name: Tingley, Suzanne Patricia
Publisher: name: University of British Columbia
Year: 2009

description: Background: Researchers assert that a woman's reproductive system is disrupted below an energy availability (EA) threshold of 25kcal/kgLBM/day, independent of exercise stress. Alternatively, research also suggests that an abrupt increase in training over an 8-week period disrupts luteal and ovulatory function in recreationally active women. It is not known whether EA and/or the stress of an abrupt program will further disrupt the luteal, ovulatory, and hormone function in gynecological mature women with regularly ovulatory and disturbed menstrual cycles. Methods: The menstrual cycle, ovulatory, and hormonal characteristics in recreationally active and gynecologically mature women (19 +/- 0.8 years) were prospectively compared between a 2- menstrual cycle control phase and an 8-week abruptly increasing training phase. Women with normally ovulatory and menstrual cycle and ovulatory disturbances were included in this study. The twenty participants sustained no injuries, as the 8-week training program increased abruptly in volume and intensity by a mean rate of 19.5% per week. Initial aerobic capacity (37.6 +/- 3ml/kg/min) non-significantly increased by 2.3ml/kg/min (p = 0.086) and ventilatory threshold significantly increased by 2ml/kg/min (p = 0.021). Regardless of a significant decrease in EA by 4.8kcal/kgLBM/day, body weight and composition remained constant over the training phase. Results: The Menstrual Cycle Diaries© and Quantitative Basal Temperatures (QBT) method of least-squares analysis revealed no significant training differences in menstrual cycle, luteal phase, and follicular phase length, as well as, ovulation status, luteal phase index, and premenstrual symptoms. Competitive enzyme immunoassays (EIAs) technique revealed no statistical control-to-training-phase differences in early follicular phase pregnanediol-3- glucuronide (PdG), luteal phase PdG and estrone conjugates (E1C), and Cortisol. The control to training change in early follicular phase E1C did approach statistical significance (p = 0.0012) and the change in energy availability accounted for 23.1% of its variability (p = 0.044). Conclusions: Menstrual cycle and ovulatory characteristics in recreationally active women are robust to an 8-week abruptly increasing training program and a mean decrease in energy availability by 4.8kcal/kgLBM/day. However, a change in energy availability by 4.8kcal/kgLBM/day accounted for 23.1% of the variance in early follicular phase E1C change from the control menstrual cycle #2 to training menstrual cycle #2.

description: The accession of Hungary to the European Union (EU) in 2004 was expected to lead to price convergence to the EU levels. The influence of national and EU policies on Hungarian producers and consumers is important as they were facing a new situation. Consumers’ welfare depends on the constantly altering world- and common market, and political actions. The purpose of this study is to analyse welfare changes and distributional impacts on Hungarian food consumers. The paper focuses on Laspeyres index, compensating variation and elasticities of demand.

description: We perform shell model calculations using a quadrupole-quadrupole interaction (Q.Q) in single a j shell space. We show that this one-parameter interaction is a good predictor of where nuclear isomerism occurs and where it does not occur. The limitations of this interaction are also discussed. We then include other interactions e.g. in the f_{7/2} shell those obtained from the (local) spectrum of a 2 particle system and then from a 2 hole system. In the g_{9/2}where there is insufficient empirical data from the 2 hole system and so various empirical interactions are used.

description: Chemical pesticides will continue to play a role in pest management for the future. In many situations, the benefits of pesticide use are high relative to the risks or there are no practical alternatives. The number and diversity of biological sources will increase, and products that originate in chemistry laboratories will be designed for particular target sites. Innovations in pesticide delivery systems in plants promise to reduce adverse environmental impacts even further. The correct use of pesticides can deliver significant socioeconomic and environmental benefits in the form of safe, healthy, affordable food; and enable sustainable farm management by improving the efficiency with which we use natural resources such as soil, water and overall land use. Genetically engineered organisms that reduce pest pressure constitute a “new generation” of pest management tools. The use of transgenic crops will probably maintain, or even increase, the need for effective resistance management programmes. However, there remains a need for new chemicals that are compatible with ecologically based pest management and applicator and worker safety. Evaluation of the effectiveness of biocontrol agents should involve consideration of long-term impacts rather than only short-term yield, as is typically done for conventional practices. But it makes sense to establish a legal framework that enables organic and pesticide-free markets to emerge and prosper so that consumers can be given an informed choice between lines of products that vary with pest management. The justifications of government intervention in the management of pest control include the need to address the externality problems associated with the human and environmental health effects of pesticides. There is underinvestment from a social perspective in private sector research because companies will compare their expected profits from their patented products resulting from research and will not consider the benefits to consumers and users. Another reason why public research might lead to innovations that elude the private sector is the different incentives that researchers in the private and public sectors face.

description: The cost-profit relations of organic and conventional farming were examined on the basis of natural and financial data of a large agricultural - company in western Hungary and of economic models characterising private farms in eastern Hungary. The differences in cost structures reflect variable conditions relating to certain crops, but they can be well explained by the differences in the technologies used. According to the production data, in organic farming direct costs per hectare were lower in all of the four examined crops. Even cost per production unit and contribution were more favourable in three of the investigated crops. Regarding the calculation done by economy models, the costs per hectare relating to the two production methods were not significantly different. Yields in organic plant production were typically lower but costs per unit and selling prices were higher. Differences in gross profits may be explained by different yields and selling prices. In a majority of the model variations organic farming is more profitable, but the extra bio price ensuring this, in accordance with trends from literature, is not sufficient for achieving a higher profit in every year.

Correlated errors are determined and their propagation through the evolution equations is performed analytically. The value for $α_s(M_Z)$ is determined to be $0.1135 +/- 0.0023/0.0026$ compatible with results from other QCD analyses. Low moments for $u_v(x)$, $d_v(x)$ and $u_v(x) - d_v(x)$ with correlated errors are calculated which may be compared with results from lattice simulations.

description: This paper takes a new empirical look at the long-standing question of the effect of exchange rate volatility on international trade flows of transition economies in Central Europe by studying the case of Hungarian agricultural exports to their export destination countries between 1999 and 2008. Based on a gravity model that controls for other factors likely to determine bilateral trade, the results show that nominal exchange rate volatility has had a significant positive effect on agricultural trade over this period. This positive effect of exchange rate volatility on agricultural exports suggests that agri-food entrepreneurs are not interested in speeding up the process of joining Hungary to the euro zone.

description: There is a continuously growing literature on the agricultural transformation in Central and Eastern European countries (see some surveys in Brooks and Nash 2002; Rozelle and Swinnen 2004). The research has focused on various aspects of transition, including land reform, farm restructuring, price and trade liberalisation, but even though Farm Accountancy Data Network (FADN) data are now available for some years, there are only a few studies (e.g. Bakucs et al. 2010, Fogarasi and Latruffe, 2007, Baráth et al., 2009) focusing on Hungarian farm performance. The objective of this paper is to shed light on some methodological issues that are needed to study Hungarian farm performance. Here we consider one aspect of farm performance, namely technical efficiency. This measure refers to whether farmers are capable of using existing technology to its full potential by producing the most possible from a given set of production factor quantities.

Para tanto, estima-se a tendência e calcula-se a correlação entre essas variáveis e; recorre-se às regressões linear e polinomial em painel, para verificar a relação determinística entre a produtividade do crédito rural e a sua taxa de crescimento para as culturas selecionadas. Os resultados evidenciam tendência positiva de crescimento do crédito e da produção para todas as culturas. O coeficiente de correlação em nível nacional para todas as culturas foi positivo e superior a 85%, exceto para o milho(15%) e feijão(53%). As estimativas econométricas mostram relação positiva entre a produtividade do crédito rural e a sua taxa de crescimento para o arroz, fumo e soja. Contudo, para o milho os resultados foram não significativos. Já para o algodão herbáceo, feijão e trigo os coeficientes apresentaram sinais contrários ao esperado a priori.-----------------------------------------------------------------------------------This article aims to show the relation between farm credit and productivity in specific kinds of plantation in Brazil from 1999 to 2005, and to carry out this objective a tendency is estimated and the correlation among the variables is calculated using the polynomial and linear regression on framework, to verify a determinist relation between productivity and farm credit and its growing tax to specific agriculture areas. The results emphasize a positive increase to farm credit and productivity in the selected plantations. The national correlation coefficient was positive in all kinds of plantations, and scores more than 85% except corn (15%) and beans (53%). The econometric estimate shows a positive relation between farm credit and productivity and its growing tax to rice, tobacco, and soy. However the results were not significant to corn but herbaceous cotton, beans and wheat the coefficient did not correspond to the expectation.

description: As recommender systems send a massive amount of content to keep users engaged, users may experience fatigue which is contributed by 1) an overexposure to irrelevant content, 2) boredom from seeing too many similar recommendations. To address this problem, we consider an online learning setting where a platform learns a policy to recommend content that takes user fatigue into account. We propose an extension of the Dependent Click Model (DCM) to describe users' behavior. We stipulate that for each piece of content, its attractiveness to a user depends on its intrinsic relevance and a discount factor which measures how many similar contents have been shown. Users view the recommended content sequentially and click on the ones that they find attractive. Users may leave the platform at any time, and the probability of exiting is higher when they do not like the content. Based on user's feedback, the platform learns the relevance of the underlying content as well as the discounting effect due to content fatigue. We refer to this learning task as "fatigue-aware DCM Bandit" problem. We consider two learning scenarios depending on whether the discounting effect is known. For each scenario, we propose a learning algorithm which simultaneously explores and exploits, and characterize its regret bound.

description: We propose a new variant of the Affleck-Dine baryogenesis mechanism in which a rolling scalar field couples directly to left- and right-handed neutrinos, generating a Dirac mass term through neutrino Yukawa interactions. In this setup, there are no explicitly CP violating couplings in the Lagrangian. The rolling scalar field is also taken to be uncharged under the $B - L$ quantum numbers. During the phase of rolling, scalar field decays generate a non-vanishing number density of left-handed neutrinos, which then induce a net baryon number density via electroweak sphaleron transitions.

description: Scale symmetry is a fundamental symmetry of physics that seems however not to be fully realized in the universe. Here, we focus on the astronomical scales ruled by gravity, where scale symmetry holds and gives rise to a truly scale invariant distribution of matter, namely it gives rise to a fractal geometry. A suitable explanation of the features of the fractal cosmic mass distribution is provided by the nonlinear Poisson--Boltzmann--Emden equation. An alternative interpretation of this equation is connected with theories of quantum gravity. We study the fractal solutions of the equation and connect them with the statistical theory of random multiplicative cascades, which originated in the theory of fluid turbulence. The type of multifractal mass distributions so obtained agrees with results from the analysis of cosmological simulations and of observations of the galaxy distribution.

A {\bf 232}, 333 (1997)] is explicitly constructed and a family of $d$-dimensional bound entangled states is designed so that the entanglement can be detected by permuting local orthogonal observables. Further the proposed physically not implementable positive maps can be physically realized by measuring a Hermitian correlation matrix of local orthogonal observables.

description: Recent years have seen an increase in the use of gigapixel-level image and video capture systems and benchmarks with high-resolution wide (HRW) shots. However, unlike close-up shots in the MS COCO dataset, the higher resolution and wider field of view raise unique challenges, such as extreme sparsity and huge scale changes, causing existing close-up detectors inaccuracy and inefficiency. In this paper, we present a novel model-agnostic sparse vision transformer, dubbed SparseFormer, to bridge the gap of object detection between close-up and HRW shots. The proposed SparseFormer selectively uses attentive tokens to scrutinize the sparsely distributed windows that may contain objects. In this way, it can jointly explore global and local attention by fusing coarse- and fine-grained features to handle huge scale changes. SparseFormer also benefits from a novel Cross-slice non-maximum suppression (C-NMS) algorithm to precisely localize objects from noisy windows and a simple yet effective multi-scale strategy to improve accuracy. Extensive experiments on two HRW benchmarks, PANDA and DOTA-v1.0, demonstrate that the proposed SparseFormer significantly improves detection accuracy (up to 5.8%) and speed (up to 3x) over the state-of-the-art approaches.

description: In 1929, Max Ernst returned to collage with La Femme 100 têtes, a cycle of 147 collages with brief captions. Although collage had been central to Ernst's early work, he shifted to frottage after the 1924 Surrealist Manifesto. This paper explores Ernst’s return to collage amid a critical moment of division within the surrealist movement, polarized by debates over surrealism's revolutionary role, collective creativity, and its relationship to political action. In this context, La Femme 100 têtes exemplifies how collage, with its use of ambiguity and refashioning of outdated materials, navigated the cultural and political impasse surrealism faced. The work challenged the modernist avant-garde’s aesthetic project, adopting a position beyond art but before politics. However, collage’s subversive potential was ultimately absorbed into art history as a new cultural form.

We use these data combined with the results from X-rays to deduce a dynamical model for the system. The data are consistent with a cluster-cluster merger viewed at a projection angle of 30-45 degrees, 0.2-0.6 Gyr prior to core passage. We estimate the richness of the combined cluster system at Abell richness class 2 or greater, suggesting the merger of two richness class 1 clusters.

description: O presente trabalho mostra que os recursos políticos e jurídicos tornaram-se tão ou mais estratégicos para citricultores e processadores de suco no Brasil que os próprios recursos financeiros, tecnológicos e organizacionais. Também, apresenta uma análise da governança citrícola brasileira atual, que está pautada por estratégias diferentes entre citricultores e processadoras : os citricultores e sua principal associação pautam suas principais ações nas utilizações de recursos políticos e algumas grandes processadoras de suco avançam com utilizações de recursos jurídicos. Esse embate revela um novo entrave para a conquista de resultados positivos pelos citricultores na rede de poder atual, pois os mandados judiciais revelam que o contrato de fornecimento de laranja tornou-se um instrumento de poder fundamental nessa rede de coordenação, causando ganhos estratégicos para as processadoras de suco após quatro anos de conquistas de recursos políticos significativos por parte dos citricultores, especialmente do estado de São Paulo.------------------------------------This essay shows that the political and legal resources, for citrus farmers, became as much strategic as financial, technological and organizational resources themselves. It This essay shows that the political and legal resources, for citrus farmers, became as much strategic as financial, technological and organizational resources themselves. ItThis essay shows that the political and legal resources, for citrus farmers, became as much strategic as financial, technological and organizational resources themselves. It presents an analysis of Brazilian citrus business governance, which is guided by different strategies between citrus farmers and processing plants: the citrus farmers and their main association guide their actions into using political resources while some big juice processing plants advance by using legal resources. This opposition represents a new obstacle to the conquest of positive results by citrus farmers in the current power network, because court orders shows that the supplying contracts of orange became an instrument of fundamental power into this coordination network, causing strategic gains for the juice processing plants after four years of significant political resource conquests by citrus farmers, specially in Sao Paulo state.

description: Este artigo procura identificar mudanças no padrão das exportações do agronegócio brasileiro nos últimos anos em direção a diversificação ou concentração, segundo as categorias destinos (bloco econômicos) ou produtos. Com esse intuito, se utiliza do Índice de Hirschman para mensurar concentração/diversificação das exportações do setor nos últimos 10 anos. Os resultados indicam que houve uma nítida diversificação dos destinos de exportação, sem que tenha ocorrido, no entanto, uma diversificação dos produtos exportados. A variação da cotação do dólar e dos preços de exportação no período tiveram uma importante influência no desempenho das exportações de produtos tradicionais, o que acarretou em uma concentração no período de desvalorização do Real e relativa desconcentração nos dois últimos anos, período em que o dólar recuou.--------------------------------------The article intends to identify changes in the patterns of Brazilian agribusiness exports in the last years towards diversification or concentration, following the categories of destinations (regional economic zones) and products. Therefore, Hirschman Index (HI) is estimated in order to measure concentration/diversification of exports in the last 10 years. Results indicate that there was a clear trend toward diversification in the destinations of exports, but there is little evidence that there was diversification in products exported. Currency fluctuation and prices of exports were identified as factors that affected the performance of traditional products exports. In those years that Real currency devaluated against dollar, exports patters changed towards concentration, and the opposite was identified in those years that Real currency appreciated.

description: Materials with high thermal conductivities (k) is valuable to solve the challenge of waste heat dissipation in highly integrated and miniaturized modern devices. Herein, we report the first synthesis of atomically thin isotopically pure hexagonal boron nitride (BN) and its one of the highest k among all semiconductors and electric insulators. Single atomic layer (1L) BN enriched with 11B has a k up to 1009 W/mK at room temperature. We find that the isotope engineering mainly suppresses the out-of-plane optical (ZO) phonon scatterings in BN, which subsequently reduces acoustic-optical scatterings between ZO and transverse acoustic (TA) and longitudinal acoustic (LA) phonons. On the other hand, reducing the thickness to single atomic layer diminishes the interlayer interactions and hence Umklapp scatterings of the out-of-plane acoustic (ZA) phonons, though this thickness-induced k enhancement is not as dramatic as that in naturally occurring BN. With many of its unique properties, atomically thin monoisotopic BN is promising on heat management in van der Waals (vdW) devices and future flexible electronics. The isotope engineering of atomically thin BN may also open up other appealing applications and opportunities in 2D materials yet to be explored.

description: We show that the complete static black p-brane supergravity solution with a single charge contains two and only two branches with respect to behavior at infinity in the transverse space. One branch is the standard family of asymptotically flat black branes, and another is the family of black branes which asymptotically approach the linear dilaton background with antisymmetric form flux (LDB). Such configurations were previously obtained in the near-horizon near-extreme limit of the dilatonic asymptotically flat p-branes, and used to describe the thermal phase of field theories involved in the DW/QFT dualities and the thermodynamics of little string theory in the case of the NS5-brane. Here we show by direct integration of the Einstein equations that the asymptotically LDB p-branes are indeed exact supergravity solutions, and we prove a new uniqueness theorem for static p-brane solutions satisfying cosmic censorship. In the non-dilatonic case, our general non-asymptotically flat p-branes are uncharged black branes on the background $AdS_{p+2}\times S^{D-p-2}$ supported by the form flux. We develop the general formalism of quasilocal quantities for non-asymptotically flat supergravity solutions with antisymmetric form fields, and show that our solutions satisfy the first law of theormodynamics. We also suggest a constructive procedure to derive rotating asymptotically LDB brane solutions.

description: O objetivo do presente estudo é analisar o processo de modernização do setor agropecuário nos COREDES do Rio Grande do Sul que tem sua base econômica vinculada ao setor agrícola. Para tanto, recorre-se à estatística multivariada – Análise de Agrupamentos, Discriminante e Fatorial –, com o intuito de identificar padrões/níveis de modernização da agropecuária nos municípios dos COREDEs agrícolas em 1995/96. Os resultados obtidos apontam para uma forte concentração da agropecuária moderna no grupo formado pelos municípios do COREDE Fronteira Oeste. Contudo, o grupo 2 tem uma situação mais estável e, o grupo 3 demonstrou sinais de transição da agricultura mais tradicional para um padrão diferenciado, caracterizado pela inovação. Por fim, há um quarto grupo, de tamanho considerável, com um padrão agropecuário mais tradicional. Palavras-chave : agricultura, análise fatorial, Conselhos Regionais de Desenvolvimento.--------------------------------This paper has objective to analyze of the modernization process of the agricultural sector in COREDES of Rio Grande do Sul, whose economical base is linked to agriculture. For this purpose, two multivariate statistics tools he statistics is applied – Factor and Cluster Analysis –, made possible the rating of the cities of the agricultural (COREDEs) of RS about their degree of modernization in the 1995/96 period. In RS, the stage of agricultural modernization of the analyzed period points to a strong concentration of modern agriculture and animal husbandry in the group made up by the cities of the Western Border COREDE. The other clustered cities did not show a local pattern of clustering. However, group 2 has a steadier situation, and group 3 showed signs of transition from a more traditional agriculture to a differentiated pattern, characterized by innovation. Finally, there is a fourth group with the worst degree of agriculture modernization of the State.

description: We show how Markov mixed membership models (MMMM) can be used to predict the degradation of assets. We model the degradation path of individual assets, to predict overall failure rates. Instead of a separate distribution for each hidden state, we use hierarchical mixtures of distributions in the exponential family. In our approach the observation distribution of the states is a finite mixture distribution of a small set of (simpler) distributions shared across all states. Using tied-mixture observation distributions offers several advantages. The mixtures act as a regularization for typically very sparse problems, and they reduce the computational effort for the learning algorithm since there are fewer distributions to be found. Using shared mixtures enables sharing of statistical strength between the Markov states and thus transfer learning. We determine for individual assets the trade-off between the risk of failure and extended operating hours by combining a MMMM with a partially observable Markov decision process (POMDP) to dynamically optimize the policy for when and how to maintain the asset.
