Campos Aleatórios Condicionais Aplicados à Detecção de Estrutura Retórica em Resumos de Textos Acadêmicos em Português (Conditional Random Fields Applied to Rhetorical Structure Detection in Academic Abstracts in Portuguese)

This paper presents CRF-AZPort, a rhetorical structure predictor for abstracts written in Portuguese. Unlike the AZPort classifier, which predicts the category of each sentence independently, the proposed predictor uses Conditional Random Fields for predicting a sequence of rhetorical categories for a given abstract. CRF-AZPort uses three new attributes in addition to the original AZPort attributes. Results show that rhetorical classification can be modeled as a sequence labeling problem and that considering rhetorical structure contributes to the classification. Resumo. Este trabalho apresenta o CRF-AZPort, um preditor de estrutura retórica para resumos científicos escritos em português. Diferente do classificador AZPort, que prediz a categoria retórica de cada sentença de forma independente, o preditor proposto utiliza Conditional Random Fields para prever uma sequência de categorias retóricas para um resumo. Além dos atributos originais do AZPort, o CRF-AZPort utiliza três novos atributos. Os resultados obtidos mostram que a classificação retórica pode ser modelada como um problema de rotulação sequencial e que considerar a estrutura como um todo contribui para a classificação.
Sound Isolation and Giant Linear Nonreciprocity in a Compact Acoustic Circulator

Acoustically Isolated The control of sound transmission is desirable in a number of circumstances from noise suppression to imaging technologies. Fleury et al. (p. 516; see the cover; see the Perspective by Cummer) studied a subwavelength acoustic meta-atom consisting of a resonant ring cavity biased by an internally circulating fluid. The direction of rotational flow of the fluid (air) changed the resonant properties of the ring cavity, allowing the propagation of sound waves within the cavity to be controlled. With several ports connected to the cavity, sound could be directed to a certain port while isolating transmission in another. Directional fluid flow is used to control and isolate the propagation of sound. [Also see Perspective by Cummer] Acoustic isolation and nonreciprocal sound transmission are highly desirable in many practical scenarios. They may be realized with nonlinear or magneto-acoustic effects, but only at the price of high power levels and impractically large volumes. In contrast, nonreciprocal electromagnetic propagation is commonly achieved based on the Zeeman effect, or modal splitting in ferromagnetic atoms induced by a magnetic bias. Here, we introduce the acoustic analog of this phenomenon in a subwavelength meta-atom consisting of a resonant ring cavity biased by a circulating fluid. The resulting angular momentum bias splits the ring’s azimuthal resonant modes, producing giant acoustic nonreciprocity in a compact device. We applied this concept to build a linear, magnetic-free circulator for airborne sound waves, observing up to 40-decibel nonreciprocal isolation at audible frequencies.
Event-triggered state fusion estimation for wireless sensor networks with feedback

In this paper, the event-triggered state fusion estimation problem is considered for wireless sensor networks with limited communication resources. We propose two event-triggered fusion estimation algorithms under sequential and parallel fusion structures, respectively, where each sensor sends its observations to the fusion center only when its event-triggering condition is satisfied. In the sequential fusion estimation algorithm, the global estimate is updated with the received sensor information sequentially. While in the parallel algorithm, local estimates are first generated and then fused to obtain the global estimate. Moreover, feedback is adopted from the fusion center to sensor scheduler modules in order to make the triggering condition adaptive. The sequential fusion estimation algorithm has better local estimation performance while the parallel algorithm outperforms in computational efficiency, robustness and fault detection. Simulation results show that by adopting event-triggered strategy, the proposed algorithms can dramatically reduce the data transmission of the system with the cost of just a slightly deterioration of the estimation performance, compared with the traditionally time-triggered scheme.

Supertree Analysis of the Plant Family Fabaceae

Abstract The “Tree-of-Life” is a national and international project to collect information aboutthe origin, evolution, and diversity of organisms, with the goal of producing a tree of all life onEarth (Pennisi, 2003). The obstacles to achieving this goal are many. From questions relatedto the kinds and number of data to be used, to building that phylogeny, to the methodologicaland computational resources required to analyze the massive amounts of data expected to benecessary to bring this to fruition. The development of efficient methods for phylogeneticanalyses of thousands (hundreds of thousands) of taxa has become increasingly important tothis endeavor, as well as somewhat controversial. Supertree construction is one of thesemethods proposed for reconstructing phylogenies on a large scale (Bininda-Emonds, 2004). This method combines phylogenetic trees (topologies), which overlap taxonomically, ratherthan the primary data, to produce a larger tree using standard methods of analyses such asparsimony. This method also has the advantage of being able to incorporate trees derived frommany different kinds of data into tree estimation. For the study presented here, acomprehensive literature search identified 185 phylogenetic trees published since 1984 on theplant family Fabacaeae (the “legumes”). Of these, 68 trees were chosen for supertree analysisand were divided into three major groups, two of which correspond to strongly-supportedmonophyletic groups identified by recent studies that sampled extensively across the family andare based on standard phylogenetic analyses of single data sets (e.g. gene sequences). Supertrees of taxa that correspond to the three subfamilies Mimosoideae, Caesalpinioideae, andPapilionoideae will be presented here.
Pediatric Bipolar Disorder: Subtype Trend and Impact of Behavioral Comorbidities

The diagnosis of pediatric bipolar disorder (PBD) has increased dramatically in community-treated youth in the past 20 years. No previous study has assessed the trend in PBD subtype diagnoses or the impact of clinician-reported behavioral comorbidities (BC) on psychotropic medication prescribing patterns. This study aims: (1) to characterize national trends in PBD visits in relation to PBD subtypes; and (2) to assess differences in socio-demographic PBD subtype diagnostic patterns and psychotropic medications prescribed in PBD visits with and without behavioral comorbidities (w/w/o BC). PBD visits for 1999–2010 from the National Ambulatory Medical Care Survey (NAMCS) data were assessed using population-weighted chi-square and logistic regression analyses. While PBD visit rates were stable across 12 years, the proportional shift of subtype diagnosis from Bipolar I (89.0%) in 1999–2002 to Bipolar Not Otherwise Specified (NOS) (74.1%) in 2007–2010 was notable. Compared with PBD without behavioral comorbidities (w/o BC), PBD visits w/BC had greater proportions of the bipolar-NOS subtype, more males, 2–14-year-olds, and more publicly-insured visits. The prescription of antipsychotics (60% vs. 61%) was common in PBD visits regardless of the presence of behavioral comorbidities. Stimulants were the predominant class prescribed for PBD visits with BC (67.8% vs. 9.4%). Antidepressants were significantly greater in PBD visits without BC (41.6% vs. 21.0%). Overall one-third of PBD youth visits were prescribed antipsychotics concomitant with other psychotropic classes. Behavioral conditions accompanying PBD visits were prominent, suggesting the need for monitoring and evaluating the outcomes of complex medication regimens in community populations.
Ectopic Expression of Human and Feline CD9 in a Human B Cell Line Confers β1 Integrin-dependent Motility on Fibronectin and Laminin Substrates and Enhanced Tyrosine Phosphorylation (*)

Few molecules have been shown to confer cell motility. Although the motility-arresting properties of anti-CD9 monoclonal antibody (mAb) suggest the transmembrane 4 superfamily (TM4SF) member CD9 can induce a motorgenic signal, gene transfection studies have failed to confirm this hypothesis. We report here that ectopic expression of human CD9 (CD9h) and feline CD9 (CD9f) in the CD9-negative, poorly motile, human B cell line Raji dramatically enhances migration across fibronectin- and laminin-coated polycarbonate filters. Migration of Raji/CD9h and Raji/CD9f on either substrate was inhibited by the anti-CD9 mAb 50H.19 and by the anti-β1 integrin mAb AP-138. Migration of Raji/CD9h on laminin was potently inhibited by the anti-VLA-6 integrin mAb GoH3 and by the anti-VLA-4 integrin mAb 44H6, whereas migration of Raji/CD9h on fibronectin was inhibited only by mAb 44H6. Since CD9h-transfected Raji cells adhered to fibronectin as effectively as mock transfectants, expression of CD9 enhanced motility, but not adhesion. CD9-enhanced migration was inhibited by the protein tyrosine kinase inhibitor herbimycin A suggesting that tyrosine phosphorylation played a role in the generation of a motorgenic signal. Raji/CD9h transfectants adherent to fibronectin expressed 6-fold higher levels of phosphotyrosine than Raji. Raji/CD9f transfectants also phosphorylated proteins on tyrosine more effectively than Raji including a protein of 110 kDa which was phosphorylated on the motility-inducing substrates laminin and fibronectin, but not on bovine serum albumin. Our results support a role for CD9 in the amplification of a motorgenic signal in B cells involving β1 integrins and the activation of protein tyrosine kinases.
Accelerating China's rural transformation

This report aims to identify and consolidate information on crucial issues that impact on rural development in China. China's rural economic achievements of the past two decades - rapid growth and declining poverty - have been remarkable. However, replicating these achievements and improving sustainability during the next two decades will be difficult as many underlying conditions have changed. Economic reforms were initiated when supply shortages constrained growth, but currently, weak demand is more constraining. Furthermore, the productivity gains are largely exhausted from transition policies and institutions; future productivity gains will come from efficiencies, stimulated by market forces, and improved productivity of scarce water and land resources, through resource conservation and new technologies. The rural-agricultural sector will remain dependent on a robust urban-industrial sector to create jobs and absorb surplus rural and agricultural labor - thereby permitting the remaining farmers access to additional land resources. An effective fiscal system, a more efficient financial system, a workable land tenure arrangement with marketable land-use rights, and improved agricultural investment incentives need to be fostered. Continued reform will entail further liberalization of production, pricing, and marketing policies. It will also entail strong government promotion of a market environment and investments in public services and infrastructure.
Study of Design Factors Affecting Turn-on Time of Silicon Controlled Rectifiers (SCRS) in 90 and 65nm Bulk CMOS Technologies

We explore the effect of layout factors on the turn-on time of silicon controlled rectifiers (SCRs) in 90nm and 65nm bulk CMOS technologies. Using a very fast transmission line pulse (VFTLP) tester, we show that a SCR in 65nm bulk CMOS technology can achieve a turn-on time of 500ps with proper design. Using device simulations, we identify factors limiting SCR turn-on time and provide a basis for the presented experimental results

Country People Moving to the Cities: The Migratory Dynamic

This article examines the migration of rural workers towards the cities in the light of national data on the two periods 1985-1990 and 1990-1995. It briefly considers the restrictions on workers’ mobility, focusing particularly on the main instrument of control, the hukou. The article highlights the finding that despite such continuing obstacles to mobility, the migratory dynamic is consistent with the deepening integration of the Chinese domestic market.
Is venture capital more than just money

This paper analyzes whether the superior performance of venture-backed firms is associated with the funding provided and/or to the value added by venture capitalists to their investee firms. Rooted on the agency and the resource-based view theories, both variables are analyzed according to the stage of development of the firm. The hypotheses are tested on a highly representative sample of Spanish venture-backed firms over the period 1993-2005. Our results show that funding is significant regardless of the stage of development of the investee firm at the time of the investment. The value added, however, is significant only for the subsample of firms at the expansion stage.
An Analysis of national average car rental rates and economic indicators

Travel suppliers have depended largely on business travel as their main source of business and profit because it is less price conscious and finicky compared to the pleasure travel market. The past recession has caused corporations to scale-down by drastically reducing business related travel; therefore, it is understood, as a majority, that the condition of the economy usually dictates future business. Car rental companies are a significant part of the travel supplier industry and it is wondered if the fluctuations in car rental rates are a direct reflection of the rise and fall of the economy also. The study will use four key economic indicators (housing starts, retail sales, car sales and unemployment) as a direct reflection of the economy. Car rental rates will then be added to notice any correlation between the two.
Surface Display of the Receptor-Binding Region of the Lactobacillusbrevis S-Layer Protein in Lactococcuslactis Provides Nonadhesive Lactococci with the Ability To Adhere to Intestinal Epithelial Cells

ABSTRACT Lactobacillus brevis is a promising lactic acid bacterium for use as a probiotic dietary adjunct and a vaccine vector. The N-terminal region of the S-layer protein (SlpA) of L. brevis ATCC 8287 was recently shown to mediate adhesion to various human cell lines in vitro. In this study, a surface display cassette was constructed on the basis of this SlpA receptor-binding domain, a proteinase spacer, and an autolysin anchor. The cassette was expressed under control of the nisA promoter in Lactococcuslactis NZ9000. Western blot assay of lactococcal cell wall extracts with anti-SlpA antibodies confirmed that the SlpA adhesion domain of the fusion protein was expressed and located within the cell wall layer. Whole-cell enzyme-linked immunosorbent assay and immunofluorescence microscopy verified that the SlpA adhesion-mediating region was accessible on the lactococcal cell surface. In vitro adhesion assays with the human intestinal epithelial cell line Intestine 407 indicated that the recombinant lactococcal cells had gained an ability to adhere to Intestine 407 cells significantly greater than that of wild-type L. lactis NZ9000. Serum inhibition assay further confirmed that adhesion of recombinant lactococci to Intestine 407 cells was indeed mediated by the N terminus-encoding part of the slpA gene. The ability of the receptor-binding region of SlpA to adhere to fibronectin was also confirmed with this lactococcal surface display system. These results show that, with the aid of the receptor-binding region of the L. brevis SlpA protein, the ability to adhere to gut epithelial cells can indeed be transferred to another, nonadhesive, lactic acid bacterium.
High‐throughput micro‐scale cultivations and chromatography modeling: Powerful tools for integrated process development

Upstream processes are rather complex to design and the productivity of cells under suitable cultivation conditions is hard to predict. The method of choice for examining the design space is to execute high‐throughput cultivation screenings in micro‐scale format. Various predictive in silico models have been developed for many downstream processes, leading to a reduction of time and material costs. This paper presents a combined optimization approach based on high‐throughput micro‐scale cultivation experiments and chromatography modeling. The overall optimized system must not necessarily be the one with highest product titers, but the one resulting in an overall superior process performance in up‐ and downstream. The methodology is presented in a case study for the Cherry‐tagged enzyme Glutathione‐S‐Transferase from Escherichia coli SE1. The Cherry‐Tag™ (Delphi Genetics, Belgium) which can be fused to any target protein allows for direct product analytics by simple VIS absorption measurements. High‐throughput cultivations were carried out in a 48‐well format in a BioLector micro‐scale cultivation system (m2p‐Labs, Germany). The downstream process optimization for a set of randomly picked upstream conditions producing high yields was performed in silico using a chromatography modeling software developed in‐house (ChromX). The suggested in silico‐optimized operational modes for product capturing were validated subsequently. The overall best system was chosen based on a combination of excellent up‐ and downstream performance. Biotechnol. Bioeng. 2015;112: 2123–2133. © 2015 Wiley Periodicals, Inc.

Changes in the levels of progesterone, corticosteroids, estrone, estradiol-17 beta, luteinizing hormone, and prolactin in the peripheral plasma of the ewe during late pregnancy and at parturition.

Serial measurements (up to four times per day) of maternal plasma progesterone, corticosteroids, estrone, estradiol-17�, LH, and prolactin have been made in six sheep, during late pregnancy and at parturition (Day 0). The mean progesterone concentration on Day -10 was 15.5 ng/ml. From Day -4 the level began to decrease and by Day 0, the mean progesterone level was 1.0 ng/ml. The mean concentrations of estrone and estradiol-17p on Day -3 (62.4 and 24.0 pg/ml, respectively) began to rise during the 48 hr preceding parturition, reaching peak values of 228.0 and 141.8 pglml, respectively. The mean corticosteroid level (17.3 ng/ml) rose during the 18 hr preceding parturition, reaching a peak of 38.6 ng/ml. Estrone, estradiol-17�, and corticosteroids returned to low levels within 12 hr after parturition. LH levels remained relatively coastant (2.0-6.0 ng/ml) from -36 h to +30 h but prolactin levels rose sharply from about Day -2. Possible explanations for the absence of an increase in LH secretion, in response to the preparturient rise in estrogens, are discussed.
The Leadership of Jesus in the Succession Process of the Disciples : A Dual Focus of Servanthood in Small Groups

Organizational structure is experiencing an increase in the use of small groups and teams as solutions to strategic concerns. The issue of succession planning within a group or organization is vital to a successful strategy. In addition, servant leadership is experiencing a resurgence of interest in organizations and in leadership research. However, servant leadership in the succession process of small groups is meager in the literature. Fortunately, fascinating incites regarding the integration of these concepts are provided through the leadership of Jesus. This endeavor explored the servant leadership of Jesus during the succession process with his small group of disciples. The narrative found in John 13 of Jesus washing the feet of the disciples was used as a basis for exploration. It was established that Jesus served God’s plan and mission while simultaneously serving his team of disciples as he prepared the team to assume their leadership roles in his subsequent absence. Therefore, it was concluded that Jesus operated in a dual-focus of servanthood. This type of servant leadership may prove beneficial to organizations in a period of leadership succession.
Do corporate bond and credit default swap markets value environmental, social or corporate governance events?

We measure the impact of negative environmental, social and governance news on corporate bond prices and credit default swap premiums for the Eurozone market. Each firm is affected at least by one piece of news related to its environmental, social and governance practices. Each news is then flagged with an indicator of importance. Ab- normal bond returns are computed by subtracting return from a matching portfolio to the return of the observed bond return. Abnormal credit default swap return is calculated with a regression of the observed bond return on an equiweighted index that is constructed to transpose our bond universe on the credit default swap market. Several parametric and non parametric tests do not show any significant impact of these negative events as a whole on corporate bond prices, even though there is evidence of some impact of two subcategories of social events. When considering all events, we find a slight but counter-intuitive decrease of the credit default swap premium within the 5 following days of the event. REMARK: We did finish the database and have now more than 2000 events associated to 212 firms. Unfortunately, the calculation of the matching portfolios takes more time than we expected due to the various constraints. However, we joined the first results for the credit default swap market (Table 7). It does not change the results we found with our subsample of 85 firms.
