Using an English noun phrase grammar defined by Hulth (2004a) as a starting point, we created an English noun phrase chunker to extract anchor text candidates identified within web-based articles. These phrases served as candidates for anchor texts linking articles within the About.com network of content sites. Freelance writers—serving as annotators with little to no training outside the domai...

Glycosylphosphatidylinositol (GPI)-anchor attachment is one of the most common posttranslational protein modifications. Using the nematode Caenorhabditis elegans, we determined that GPI-anchored proteins are present in germline cells and distal tip cells, which are essential for the maintenance of the germline stem cell niche. We identified 24 C. elegans genes involved in GPI-anchor synthesis. ...

Most bacterial membranes contain one or two type I signal peptidases (SPases) for the removal of signal peptides from export proteins. For Streptomyces lividans, four different type I SPases (denoted SipW, SipX, SipY, and SipZ) were previously described. In this communication, we report the experimental determination of the membrane topology of these SPases. A protease protection assay of SPase...

This paper presents the methods of KECIR at NTCIR-10 Cross-Lingual Link Discovery Task. Two architectures of systems are designed, both of which consist of three common modules such as anchor detection, anchor translation and link discovery. In KECIR A2F C2E 03 FSCLIR and KECIR A2F C2E 04 FSCLIR, monolingual link discovery module is considered. In order to detect anchor, feature selection metho...

We perform a comprehensive examination of the recently proposed anchor method for topic model inference using topic interpretability and held-out likelihood measures. After measuring the sensitivity to the anchor selection process, we incorporate L2 and Beta regularization into the optimization objective in the recovery step. Preliminary results show that L2 improves heldout likelihood, and Bet...

Anchor points play an important role in DEA theory and application. They define the transition from the efficient frontier to the “free-disposability” portion of the boundary. Our objective is to use the geometrical properties of anchor points to design and test an algorithm for their identification. We focus on the variable returns to scale production possibility set; our results do not depend...

An anchor for motoring oxoplasma gondii , a parasite that can cause blindness and brain damage in immunocompromised individuals, spreads around the body and penetrates into cells using a bizarre spinning and corkscrewing motility. This motility is not dependent on any easily visible structure, such as a flagellum or lamellipodia, and the cell moves without changing shape. Now, Gaskins et al. (p...

Building on our previous work in score following, we suggest that research on musical pattern significance, representation and categorization can be usefully integrated into a score follower to automatically identify unique melodic signatures in a composition. These signatures may then be calculated and analyzed over the entirety of a composition providing anchor points. Anchor points replace w...

Focused web crawling traverses theWeb to collect documents on a specific topic. This is not an easy task, since focused crawlers need to identify the next most promising link to follow based on the topic and the content and links of previously crawled pages. In this paper, we present a framework based on Maximum Entropy Markov Models(MEMMs) for an enhanced focused web crawler to take advantage ...

Offshore anchor piles are seafloor moorings that keep the position of floating structures during a harsh environment. These piles are usually subjected to a wide range of monotonic and cyclic lateral-to-oblique pullout forces. Centrifuge tests were carried out to study the behavior of offshore anchor piles under mooring forces in saturated dense sand. The tests were carried out at different loa...
