This paper studies global ranking problem by learning to rank methods. Conventional learning to rank methods are usually designed for ‘local ranking’, in the sense that the ranking model is defined on a single object, for example, a document in information retrieval. For many applications, this is a very loose approximation. Relations always exist between objects and it is better to define the ...

Potassium, an Artificial Sweetener In their article “First Experimental Demonstration of the Multipotential Carcinogenic Effects of Aspartame Administered in the Feed of Sprague-Dawley Rats,” Soffritti et al. (2006) present interesting data on the carcinogenic effects of longterm exposure to aspartame, an artificial sweetener, in experimental animals (rats). Recently, aspartame was supplanted a...

Materials and Methods: Medically unremarkable 215 patients were included in this study and allocated into 2 groups. The first group consisted of 125 patients (58 females, 67 males, mean age 52 yrs) in whom 445 implants were placed in a 2-stage procedure. These patients received penicillin or clindamycin preoperatively only. The second group consisted of 90 patients (46 females, 44 males, mean a...

Most versions of the Peterson-Gorenstein-Zierler (PGZ) decoding algorithm are not true bounded distance decoding algorithms in the sense that when a received vector is not in the decoding sphere of any codeword, the algorithm does not always declare a decoding failure. For a t-error-correcting BCH code, if the received vector is at distance i, i t, from a codeword in a supercode with BCH distan...

T here are 14 different dyneins in the human genome, but 13 of these are found in cilia and fl agella. Just one—cytoplasmic dynein 1—handles the bulk of minus end–directed microtubule trafficking for organelles, vesicles, and other cargoes. It is only recently that scientists have started to understand this motor better, and, surprisingly, they have discovered that how it walks can be quite ran...

We give a new and relatively easy proof of the splitting theorem of the second author for the spaces in the Omega spectrum for BP . We then give the first published proofs of our similar theorems for the spectra P (n).

Using Lexical and Compositional Semantics to Improve HPSG Parse Selection Chair of the Supervisory Committee: Dr. Emily Bender University of Washington Accurate parse ranking is essential for deep linguistic processing applications and is one of the classic problems for academic research in NLP. Despite significant advances, there remains a big need for improvement, especially for domains where...

In 1929, Zermelo proposed a probabilistic model for ranking by paired comparisons and showed that this model produces a unique ranking of the objects under consideration when the outcome matrix is irreducible. When the matrix is reducible, the model may yield only a partial ordering of the objects. In this paper, we analyze a natural extension of Zermelo’s model resulting from a singular pertur...
