Automated cross-lingual link discovery in Wikipedia

At NTCIR-9, we participated in the cross-lingual link discovery (Crosslink) task. In this paper we describe our approaches to discovering Chinese, Japanese, and Korean (CJK) cross-lingual links for English documents in Wikipedia. Our experimental results show that a link mining approach that mines the existing link structure for anchor probabilities and relies on the “translation” using cross-lingual document name triangulation performs very well. The evaluation shows encouraging results for our system.

Overview of the NTCIR-9 crosslink task : cross-lingual link discovery

This paper presents an overview of NTCIR-9 Cross-lingual Link Discovery (Crosslink) task. The overview includes: the motivation of cross-lingual link discovery; the Crosslink task definition; the run submission specification; the assessment and evaluation framework; the evaluation metrics; and the evaluation results of submitted runs. Cross-lingual link discovery (CLLD) is a way of automatically finding potential links between documents in different languages. The goal of this task is to create a reusable resource for evaluating automated CLLD approaches. The results of this research can be used in building and refining systems for automated link discovery. The task is focused on linking between English source documents and Chinese, Korean, and Japanese target documents.

The effectiveness of cross-lingual link discovery

This paper describes the evaluation in benchmarking the effectiveness of cross-lingual link discovery (CLLD). Cross lingual link discovery is a way of automatically finding prospective links between documents in different languages, which is particularly helpful for knowledge discovery of different language domains. A CLLD evaluation framework is proposed for system performance benchmarking. The framework includes standard document collections, evaluation metrics, and link assessment and evaluation tools. The evaluation methods described in this paper have been utilised to quantify the system performance at NTCIR-9 Crosslink task. It is shown that using the manual assessment for generating gold standard can deliver a more reliable evaluation result.

Progress towards the total synthesis of a spermine-conjugated dynemicin analog

Progress towards the synthesis of the spermine-conjugated Dynemicin analog 4 is described. The synthetic route starts with the Michael addition of menthyl acetoacetate to trans-ethyl crotonate followed by a Dieckman condensation to form the cyclohexanedione 14 which, through a series of chemical reactions, is transformed into the quinone imine 6. Key features in the route include the Suzuki coupling reaction of the aryl boronic acid 11 and the enol triflate 12, thermal deprotection/internal amidation of the biaryl 19, cis addition of the (Z)-enediyne 33 to the quinoline 25, intramolecular acetylide addition to a carbonyl within the ketone 29, and an addition/elimination of the cyanophthalide to the quinone imine 6 to form the anthraquinone 36 utilizing the Kraus and Sugimoto methodology.

Small-molecule-directed assembly: A gold nanoparticle-based strategy for screening of homo-adenine DNA duplex binders

By using AuNP-modified homo-adenine DNA conjugate as a model system, simple colorimetric and resonance Rayleigh scattering assays have been developed for screening small molecules that trigger the formation of the non-Watson-Crick homo-adenine duplexes. The assay presented here is more simplified in format as it involves only one type of ssDNA modified Au-NP, and can be easily adapted to high-throughput screening.

Reasons for late presentation to HIV care in Switzerland.

INTRODUCTION: Late presentation to HIV care leads to increased morbidity and mortality. We explored risk factors and reasons for late HIV testing and presentation to care in the nationally representative Swiss HIV Cohort Study (SHCS). METHODS: Adult patients enrolled in the SHCS between July 2009 and June 2012 were included. An initial CD4 count <350 cells/µl or an AIDS-defining illness defined late presentation. Demographic and behavioural characteristics of late presenters (LPs) were compared with those of non-late presenters (NLPs). Information on self-reported, individual barriers to HIV testing and care were obtained during face-to-face interviews. RESULTS: Of 1366 patients included, 680 (49.8%) were LPs. Seventy-two percent of eligible patients took part in the survey. LPs were more likely to be female (p<0.001) or from sub-Saharan Africa (p<0.001) and less likely to be highly educated (p=0.002) or men who have sex with men (p<0.001). LPs were more likely to have their first HIV test following a doctor's suggestion (p=0.01), and NLPs in the context of a regular check-up (p=0.02) or after a specific risk situation (p<0.001). The main reasons for late HIV testing were "did not feel at risk" (72%), "did not feel ill" (65%) and "did not know the symptoms of HIV" (51%). Seventy-one percent of the participants were symptomatic during the year preceding HIV diagnosis and the majority consulted a physician for these symptoms. CONCLUSIONS: In Switzerland, late presentation to care is driven by late HIV testing due to low risk perception and lack of awareness about HIV. Tailored HIV testing strategies and enhanced provider-initiated testing are urgently needed.

Caracterización de los pacientes con hemorragia de vías digestivas altas no varicosa atendidos en el Hospital Universitario de la Samaritana, Cundinamarca

La hemorragia de vías digestivas altas (HVDA) es una emergencia frecuente. La etiología más común es la úlcera péptica. La restauración del volumen intravascular y la presión arterial son la prioridad del manejo. La endoscopia (EGD) debe realizarse luego de la reanimación inicial y lograda la estabilización hemodinámica, tratar la lesión subyacente mediante hemostasia. Se realiza un estudio en un hospital de referencia de tercer nivel, Cundinamarca, Colombia Materiales y métodos: Estudio descriptivo retrospectivo, datos obtenidos de la historia clínica electrónica de pacientes adultos que consultaron por urgencias en el Hospital Universitario de la Samaritana (HUS) por HVDA, diagnosticada por hematemesis, melenas, hematoquezia y/o anemia; a quienes se les realizó EGD durante abril del 2010 - abril del 2011. Resultados: Se atendieron 385 pacientes en el período de estudio, 100 fueron excluidos debido a hemorragia secundaria a várices esofágicas, historia incompleta y hemorragia digestiva baja, para un total de 285 pacientes analizados. El 69.1% eran mayores de 60 años. El 73.3% presentaba hipertensión arterial, el 55.1% reportaba ingesta de Anti-inflamatorios no esteroideos (AINES) y Aspirina (ASA). El 19.6% reportaba episodios de sangrado previos y 17.9% presentó inestabilidad hemodinámica. Sesenta y tres pacientes (22,1%) requirieron hemostasia endoscópica, treinta y dos (11.2%) presentaron resangrado. La mortalidad reportada fue del 13.1%, del cual 55.3% correspondía a hombres. Discusión: La mayoría de la población atendida en el HUS por HVDA son adultos mayores de 60 años. La úlcera péptica, continúa siendo el diagnóstico más frecuente asociado al uso de AINES y ASA.

A simple syllogism-solving test: empirical findings and implications for g research

It has been reported that the ability to solve syllogisms is highly g-loaded. In the present study, using a self-administered shortened version of a syllogism-solving test, the BAROCO Short, we examined whether robust findings generated by previous research regarding IQ scores were also applicable to BAROCO Short scores. Five syllogism-solving problems were included in a questionnaire as part of a postal survey conducted by the Keio Twin Research Center. Data were collected from 487 pairs of twins (1021 individuals) who were Japanese junior high or high school students (ages 13–18) and from 536 mothers and 431 fathers. Four findings related to IQ were replicated: 1) The mean level increased gradually during adolescence, stayed unchanged from the 30s to the early 50s, and subsequently declined after the late 50s. 2) The scores for both children and parents were predicted by the socioeconomic status of the family. 3) The genetic effect increased, although the shared environmental effect decreased during progression from adolescence to adulthood. 4) Children's scores were genetically correlated with school achievement. These findings further substantiate the close association between syllogistic reasoning ability and g.

The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.
