A Generalized Tree Matching Algorithm Considering Nested Lists for Web Data Extraction

This paper studies structured data extraction from Web pages. One of the effective methods is tree matching, which can detect template patterns from web pages used for extraction. However, one major limitation of existing tree matching algorithms is their inability to deal with embedded lists with repeated patterns. In the Web context, lists are everywhere, e.g., lists of products, jobs and publications. Due to the fact that lists in trees may have different lengths, the match score of the trees can be very low although they follow exactly the same template pattern. To make the matter worse, a list can have nested lists in it at any level. To solve this problem, existing research uses various heuristics to detect candidate lists first and then applies tree matching to generate data extraction patterns. This paper proposes a generalized tree matching algorithm by extending an existing tree matching algorithm with the ability to handle nested lists through a novel grammar generation algorithm. To the best of our knowledge, this is the first tree matching algorithm that is able to consider lists. In addition, it is well-known that there are two problem formulations for Web data extraction: (1) pattern generation based on multiple pages following the same template, and (2) pattern generation based on a single page containing lists of data instances following the same templates (each list may use a different template). These two problems are currently solved using different algorithms. The proposed (single) algorithm is able to solve both problems effectively. Extensive experiments show that the new algorithm outperforms the state-of-the-art existing systems for both problems considerably.
Human Herpesvirus 8–Related Primary Effusion Lymphoma After Liver Transplantation

Primary effusion lymphoma is a rare subclass of non‐Hodgkin lymphoma associated with human herpesvirus 8 infection and principally seen in human immunodeficiency virus–positive patients. We report on the case of a 72‐year‐old human immunodeficiency virus–negative male with a hepatic transplant 10 years prior, who presented with a symptomatic right‐sided pleural effusion and was found to have primary effusion lymphoma by flow cytometric and cytopathologic examination. Immunohistochemistry of his lymphoma cells was positive for human herpesvirus 8. Both he and his donor had no identifiable risk factors for human herpesvirus 8 infection. The patient was intolerant of antiviral therapy and chemotherapy, dying 7 months after diagnosis. Posttransplant primary effusion lymphoma is exceedingly rare and carries a very poor prognosis. Individualized treatment strategies are necessary given the scant body of published literature with guidance based solely on case reports.
The politics of women's biology

"Exposing the ideological bases of the medical/scientific information (and disinformation) we receive, Hubbard . gives us a book sophisticated in its analysis but accessible in its style. " --Ms. Magazine For a range of historical and contemporary issues in eugenics, human evolution, and procreative technology, Ruth Hubbard explains why scientific descriptions and choices should not generalize human, or female, attributes without acknowledging the realities of people's lives. Sophisticated in its analysis, yet not at all technical in its exposition, this book will find a wide readership among feminists, the general public, and the scientific community.
Interactive Analytical Processing in Big Data Systems: A Cross-Industry Study of MapReduce Workloads

Within the past few years, organizations in diverse industries have adopted MapReduce-based systems for large-scale data processing. Along with these new users, important new workloads have emerged which feature many small, short, and increasingly interactive jobs in addition to the large, long-running batch jobs for which MapReduce was originally designed. As interactive, large-scale query processing is a strength of the RDBMS community, it is important that lessons from that field be carried over and applied where possible in this new domain. However, these new workloads have not yet been described in the literature. We fill this gap with an empirical analysis of MapReduce traces from six separate business-critical deployments inside Facebook and at Cloudera customers in e-commerce, telecommunications, media, and retail. Our key contribution is a characterization of new MapReduce workloads which are driven in part by interactive analysis, and which make heavy use of query-like programming frameworks on top of MapReduce. These workloads display diverse behaviors which invalidate prior assumptions about MapReduce such as uniform data access, regular diurnal patterns, and prevalence of large jobs. A secondary contribution is a first step towards creating a TPC-like data processing benchmark for MapReduce.
Treatment of Postoperative Nausea and Vomiting after Outpatient Surgery with the 5‐HT3 Antagonist Ondansetron

BackgroundPostoperative nausea and vomiting following outpatient surgery can significantly delay discharge. This study evaluates the safety and efficacy of ondansetron (a new 5-HT, antagonist) in the treatment of postoperative nausea and vomiting in patients following outpatient surgery. MethodsFive hundred outpatient surgical patients (53 male and 447 female), receiving general endotracheal anesthesia, were studied at ten centers. Patients were stratified by gender and received, in a randomized, double-blind manner, 1, 4, or 8 mg ondansetron or placebo in response to nausea and/or vomiting postoperatively. Episodes of vomiting, nausea scores, adverse events, vital signs, and laboratory values were evaluated before and during the 24 h after study drug administration. ResultsComplete response to study medication (no vomiting and/or retching, and no rescue antiemetic over the initial 0–2-h period) was more frequent in the ondansetron groups (1 mg 57%, 4 mg 61%, and 8 mg 57%) than in the placebo group (30%, P <.001). For the 0–24-h study a complete response occurred in only 15% of the placebo group compared to 41%, 47%, and 47% of the 1-, 4-, and 8-mg ondansetron groups, respectively (P <.001 for all comparisons with placebo). Median nausea scores (range 0–10) during the initial observation period (0–2 h) were significantly lower for all doses of ondansetron (1.3, 0.8, 1.8 for 1, 4, and 8 mg, respectively) as compared with placebo (2.3). No significant differences occurred in hemodynamic stability, incidence of adverse events, or changes in laboratory values in the ondansetron groups compared to the placebo group. ConclusionsOndansetron, in doses less than 8 mg, is a safe, effective antiemetic for treating postoperative nausea and vomiting.
Mode of inheritance of decreased C3b receptors on erythrocytes of patients with systemic lupus erythematosus.

The erythrocytes of patients with systemic lupus erythematosus have been shown to have a decreased number of receptors for the major cleavage fragment of the third component of complement (C3b). We studied the basis for this decreased number of C3b receptors by measuring the uptake of anti-C3b-receptor antibody on cells from 113 normal subjects, 38 patients with systemic lupus erythematosus, 14 of their spouses, and 47 of their relatives. The normal subjects had 5014 +/- (mean +/- S.E.M.) receptor sites per cell, but the patients and their relatives had significantly fewer sites--2809 +/- 241 and 3167 +/- 196, respectively (P less than 0.0005). The number of sites in the patients' spouses did not differ from normal (P greater than 0.3). Three phenotypes, indicated by the numbers of receptors, occurred in the normal population; a high phenotype (HH, with 5500 to 8500 sites per cell), an intermediate phenotype (HL, with 3000 to 5499), and a low phenotype (LL, less than 3000). These three phenotypes were present in 34, 54, and 12 percent, respectively, of the normal subjects; in contrast, 5, 42, and 53 per cent of patients had these respective phenotypes. Pedigree analyses indicated that these phenotypes were inherited in an autosomal codominant manner. We conclude that the decreased number of C3b receptors in lupus is inherited, not acquired.
Developing Guidelines for Domestic Violence Offender Programs

Summary This article reviews research on domestic violence that can help inform the development of guidelines for programs for men who batter. It also illustrates some successes and problems in other fields that might be instructive for the domestic violence field. Firm conclusions about “best practice” guidelines for intervention seem to be premature because of flaws in evaluation studies. In addition, there is growing evidence of variability among men who batter on dimensions such as severity of violence, childhood traumas, generality of violence and personality traits. Programs also need to be able to respond to motivational and cultural difference among abusers. Existence of variability implies the need for multiple forms of interventions.
Scaling Relations for Turbulence in the Multiphase Interstellar Medium

We employ a generalization of the She & Lévêque model to study velocity scaling relations based on our simulations of thermal instability-induced turbulence. Being a by-product of the interstellar phase transition, such multiphase turbulence tends to be more intermittent than compressible isothermal turbulence. Due to radiative cooling, which promotes nonlinear instabilities in supersonic flows, the Hausdorff dimension of the most singular dissipative structures, D, can be as high as 2.3, while in supersonic isothermal turbulence D is limited by shock dissipation to D ⩽ 2. We also show that single-phase velocity statistics carry only incomplete information on the turbulent cascade in a multiphase medium. We briefly discuss the possible implications of these results on the hierarchical structure of molecular clouds and on star formation.
Decomposing interactions using GLM in combination with the COMPARE, LMATRIX and MMATRIX subcommands in SPSS

In this tutorial, we provide researchers who use SPSS step-by-step instructions for decomposing interactions when a three-way ANOVA is conducted using the GLM procedure. We start with a demonstration of how a two-way interaction can be decomposed using the COMPARE subcommand in combination with syntax. Then, we provide instructions with examples for conducting simple interaction and secondorder simple effects analyses for three-way ANOVAs with between-subjects, withinsubjects, and mixed betweenand within-subjects variables using the LMATRIX or MMATRIX subcommands. Provided in Appendices are general rules that can be used to derive design-specific LMATRIX and MMATRIX subcommands.
Low Molecular Weight Xylanase from Trichoderma viride VKF3 for Bio-bleaching of Newspaper Pulp

Xylanase is a major enzyme used in the paper and pulp industries for bio-bleaching applications. There are possibilities for xylanase with better properties suitable for industrial applications. This paper focused on a potential xylanolytic fungus, Trichoderma viride VKF-3, obtained from a mangrove soil sample. Optimum conditions for xylanase production were tested by culturing T. viride VKF3 under varying carbon and nitrogen sources, medium pH, and incubation temperature. The isolate T. viride VKF3 achieved a maximum of 3.045 IU/mL of xylanase activity by utilizing coconut oil cake as a substrate. During purification, 84% yield was obtained with 40% ammonium sulphate. The enzyme activity was confirmed through zymogram analysis, and a band was observed at 14 kDa. The xylanase facilitated maximum hexenuronic acid release with a 30% enzyme dosage following 4 h of incubation. Moreover, the Kappa number tended to decrease with increased enzyme dosage and incubation time. There was a Δ brightness of 11% following 4 h of enzymatic treatment. Strength properties, such as the tensile, burst indices, and folding endurance, was improved during the xylanase assisted deinking of pulp. Hence, the present xylanase was found to be suitable for the bio-bleaching of newspaper waste via an eco-friendly process.
Nucleotide sequence and characterization of the traABCD region of IncI1 plasmid R64

A 3.6-kb BglII-SmaI segment of the transfer region of IncI1 plasmid R64drd-11 was sequenced and characterized. Analysis of the DNA sequence indicated the presence of four genes, traA, traB, traC, and traD, in this region. The expression of the traB, traC, and traD genes was examined by maxicell experiments and that of the traA gene was examined by constructing the traA-lacZ fusion gene. The introduction of frameshift mutations into the four genes indicated that the traB and traC genes are essential for conjugal transfer in liquid medium and on a solid surface. Both were also required for the formation of the thin pilus, which is the receptor for phages I alpha and PR64FS. Upstream of the traA gene, a promoter sequence for sigma 70 of E. coli RNA polymerase was identified by S1 nuclease mapping and primer extension experiments.
Ofatumumab monotherapy in rituximab-refractory follicular lymphoma: results from a multicenter study.

New treatments are required for rituximab-refractory follicular lymphoma (FL). In the present study, patients with rituximab-refractory FL received 8 weekly infusions of ofatumumab (CD20 mAb; dose 1, 300 mg and doses 2-8, 500 or 1000 mg; N = 116). The median age of these patients was 61 years, 47% had high-risk Follicular Lymphoma International Prognostic Index scores, 65% were chemotherapy-refractory, and the median number of prior therapies was 4. The overall response rate was 13% and 10% for the 500-mg and 1000-mg arms, respectively. Among 27 patients refractory to rituximab monotherapy, the overall response rate was 22%. The median progression-free survival was 5.8 months. Forty-six percent of patients demonstrated tumor reduction 3 months after therapy initiation, and the median progression-free survival for these patients was 9.1 months. The most common adverse events included infections, rash, urticaria, fatigue, and pruritus. Three patients experienced grade 3 infusion-related reactions, none of which were considered serious events. Grade 3-4 neutropenia, leukopenia, anemia, and thrombocytopenia occurred in a subset of patients. Ofatumumab was well tolerated and modestly active in this heavily pretreated, rituximab-refractory population and is therefore now being studied in less refractory FL and in combination with other agents in various B-cell neoplasms. The present study was registered at www.clinicaltrials. gov as NCT00394836.
Synthesis of Narrow Molecular Weight Distribution Norbornene-Lactone Functionalized Polymers by Nitroxide-Mediated Polymerization: Candidates for 193-nm Photoresist Materials

One hundred ninety three-nanometer candidate photoresist materials were synthesized by nitroxide-mediated polymerization (NMP). Statistical copolymerizations of 5-methacryloyloxy-2,6-norboranecarbolactone (NLAM) with 5–10 mol% of controlling co-monomers (which are necessary for controlled polymerizations of methacrylates by NMP with the initiator used) in the feed, such as styrene (ST), p-acetoxystyrene (AcOST), 2-vinyl naphthalene (VN) and pentafluorostyrene (PFS), using the unimolecular BlocBuilder® initiator in 35 wt% dioxane solution at 90 °C were performed. As little as 5 mol% controlling comonomer in the feed was demonstrated to be sufficient to lead to linear evolution of number average molecular weight with respect to conversion up to 50%, and the resulting copolymers had dispersities of ~1.3 in most cases, an attractive feature for reducing line width roughness (LWR) in photoresists. The copolymers generally showed relatively low absorbance at 193 nm, comparable to other 193-nm candidate photoresists reported previously, despite the inclusion of a small amount of the styrenic co-monomers in the copolymer.
Research Paper Series Globalisation and Labour Markets Programme Trade, Turnover, and Tithing the Centre Acknowledges Financial Support from the Leverhulme Trust under Programme Grant F114/bf Trade, Turnover, and Tithing Non-technical Summary

Abstract This paper develops a political economy model to test the proposition that the effect of international trade on the distribution of income is systematically related to the extent of labor-market turnover. The model reveals that trade benefits the abundant factor and hurts the scarce factor regardless of where those factors are employed if turnover is high, but benefits factors in exporting industries and harms those in import-competing industries when turnover is low. We test these predictions using data on campaign contributions given by industry-specific political action committees to congressional representatives who subsequently voted for or against trade-liberalizing legislation. We find empirical evidence in favor of the model's predictions. One of the main themes of international economics is that trade relationships have implications for the distribution of income. While there is no question that trade policy creates winners and losers, the identity of the winners and losers depends on the degree to which factors of production can move between sectors. The polar extremes are embodied in the in the Heckscher-Ohlin-Samuelson (HOS) model, where factors are assumed to be perfectly mobile, and the Ricardo-Viner model where some factors are assumed to be completely immobile. One of the fundamental results of the HOS model is the Stolper-Samuelson theorem, which demonstrates that the economy's abundant factor benefits from trade liberalization, even if employed in the declining import-competing sector, and the economy's scarce factor is harmed by trade liberalization, even if employed in the expanding export sector. By contrast, analysis of the Ricardo-Viner model reveals that factors trapped in the import-competing sector are harmed by trade reform regardless of relative abundance, while factors tied to the export sector benefit. One of the problems with the HOS and RV models is that the labor market experience of many workers bears little resemblance to what is modeled in either framework. For example, low-wage workers typically cycle between employment and unemployment and often find it difficult to find new jobs quickly. Yet, the HO and RV models both assume that all factors are fully employed at all times. In a recent paper, Davidson, Martin, and Matusz (JIE 1999) extended the HOS model to allow for unemployment and examined how the model's traditional results were altered. In doing so, they derived a new theory …
Adaptive Control of Manipulators Forming Closed Kinematic Chain With Inaccurate Kinematic Model

The problem of self-tuning control of cooperative manipulators forming closed kinematic chain in the presence of inaccurate kinematics model is addressed in this paper. The kinematic parameters pertaining to the relative position/orientation uncertainties of the interconnected manipulators are updated online by two cascaded estimators in order to tune a cooperative controller for achieving accurate motion tracking with minimum-norm actuation force. This technique permits accurate calibration of the relative kinematics of the involved manipulators without needing high precision end-point sensing or force measurements, and hence, it is economically justified. Investigating the stability of the entire real-time estimator/controller system reveals that the convergence and stability of the adaptive control process can be ensured if 1) the direction of angular velocity vector does not remain constant over time, and 2) the initial kinematic parameter error is upper bounded by a scaler function of some known parameters. The adaptive controller is proved to be singularity-free even though the control law involves inverting the approximation of a matrix computed at the estimated parameters. Experimental results demonstrate the sensitivity of the tracking performance of the conventional inverse dynamic control scheme to kinematic inaccuracies, while the tracking error is significantly reduced by the self-tuning cooperative controller.
Variation in LPA Is Associated with Lp(a) Levels in Three Populations from the Third National Health and Nutrition Examination Survey

The distribution of lipoprotein(a) [Lp(a)] levels can differ dramatically across diverse racial/ethnic populations. The extent to which genetic variation in LPA can explain these differences is not fully understood. To explore this, 19 LPA tagSNPs were genotyped in 7,159 participants from the Third National Health and Nutrition Examination Survey (NHANES III). NHANES III is a diverse population-based survey with DNA samples linked to hundreds of quantitative traits, including serum Lp(a). Tests of association between LPA variants and transformed Lp(a) levels were performed across the three different NHANES subpopulations (non-Hispanic whites, non-Hispanic blacks, and Mexican Americans). At a significance threshold of p<0.0001, 15 of the 19 SNPs tested were strongly associated with Lp(a) levels in at least one subpopulation, six in at least two subpopulations, and none in all three subpopulations. In non-Hispanic whites, three variants were associated with Lp(a) levels, including previously known rs6919246 (p = 1.18×10−30). Additionally, 12 and 6 variants had significant associations in non-Hispanic blacks and Mexican Americans, respectively. The additive effects of these associated alleles explained up to 11% of the variance observed for Lp(a) levels in the different racial/ethnic populations. The findings reported here replicate previous candidate gene and genome-wide association studies for Lp(a) levels in European-descent populations and extend these findings to other populations. While we demonstrate that LPA is an important contributor to Lp(a) levels regardless of race/ethnicity, the lack of generalization of associations across all subpopulations suggests that specific LPA variants may be contributing to the observed Lp(a) between-population variance.
Regression-based reference limits for serum transferrin receptor in children 6 months to 16 years of age.

Serum soluble transferrin receptor (sTfR) has been established in recent years as a powerful tool for detecting iron deficiency (ID) in adults, especially in distinguishing between iron deficiency anemia (IDA) and anemia of chronic disease (1)(2)(3)(4)(5)(6)(7)(8). Investigations regarding sTfR as a measure of iron status in infants and children have provided promising results, including evidence that, in infants, sTfR concentrations may be superior to ferritin measurements in diagnosing ID (9). However, to date, concrete reference values and other decision-supporting limits for the commercially available methods have been virtually absent, and the age-relatedness of sTfR concentrations, although introduced as a concept, has not been unequivocally modeled statistically (10)(11)(12)(13)(14)(15). In this study we measured the sTfR concentrations from a selection of 301 healthy children, 6 months to 18 years of age, using a commercially available automated immunoturbidimetric assay. We then used a regression-based method to construct age-dependent 2.5% and 97.5% reference limits for sTfR as well as 95% confidence intervals for these limits in our population (16). The purpose was to demonstrate consistent age-dependent changes in sTfR concentrations and to establish appropriate reference limits to enable the use of sTfR measurements in routine pediatric clinical practice. A total of 301 children (130 boys and 171 girls; age range, 6 months to 18 years) were included in the healthy population of this study. The selection was made on the basis of detailed anamnesis and laboratory tests. Febrile episodes during the preceding 6 weeks, diet restrictions, chronic inflammatory or renal diseases, hematological diseases, recent iron supplementation, ongoing inflammation (C-reactive protein >10 mg/L; erythrocyte sedimentation rate >6 mm/h), anemia or abnormal red cell indices (17), and low ferritin concentrations (<10 …
