Private information retrieval (PIR) schemes enable a user to access one or more servers that hold copies of a database and privately retrieve parts of the n bits of data stored in the database. This means that the queries give each individual database no partial information (in the information theoretic or computational sense) on the identity of the item retrieved by the user. All known PIR sch...

Keyword advertising, or “sponsored links” that appear alongside online search results or other online content, has grown into a multibillion-dollar market. Providers of keyword advertising, such as Google and Yahoo, profit by auctioning keywords to advertisers. An issue of increasing importance for advertising providers is the “share structure” problem—that is, of the total available resources ...

In this paper we introduce a minimalist hypothesis for keywords extraction: keywords can be extracted from text documents by considering concepts underlying document terms. Furthermore, central concepts are individuated as the concepts that are more related to title concepts. Namely, we propose five metrics, that are diverse in essence, to compute the centrality of concepts in the document body...

•Extending our previous work on visual keywords, we use the concept of template-based visual keywords using MPEG-7 color descriptors. MPEG-7, also called the Multimedia Content Description Interface, has been a standard for many years. These color descriptors have the ability to characterize perceptual color similarity and need relatively low complexity operations to extract them, besides being...

cated no differences (P > 0.10) between the corn rootworm protected corn and non-transgenic control corn for nitrogen intake (0.04 versus 0.04 lb/d), nitrogen digested (0.03 versus 0.03 lb/d), nitrogen retained (0.01 versus 0.01 lb/d), or nitrogen digestibility (77.30 versus 78.30%), respectively. The results of this experiment indicate that energy and nitrogen utilization are similar between d...

An experiment was conducted to determine the true ileal digestibility (TID) and the true total tract digestibility (TTTD) of acid-hydrolyzed ether extract (AEE) in extracted corn oil, high-oil corn, distillers dried grains with solubles (DDGS), corn germ, and high protein distillers dried grains (HP DDG) and to compare these values to the TID and TTTD of AEE in full-fat soybeans. Nineteen barro...

We evaluated the effect of wet corn gluten feed and a novel product containing raw soybean hulls and corn steep liquor on performance in lactating dairy cows. Forty-six multiparous Holstein cows were used in a randomized incomplete block design. Cows were housed in tie stalls for the first 13 weeks of lactation and moved to group pens for the remainder of the study. Cows were blocked by calving...

<span>Intensive dairy farming systems in the sandy soil of northwestern Morocco are based on three successive forage crops per year, including corn. The aim was to evaluate productivity and quality different intensive crop successions corn soil. Three year (winter, spring, summer cropping seasons) were tested according six successions: 1. fallow-corn-corn, 2. oat-corn-corn, 3. berseem-cor...

Two hundred eighty nursery pigs (initially 30.9 lb) were used in a 21-d growth assay to determine the energy value of ground corn germ relative to corn oil in nursery diets. Increasing dietary corn oil linearly decreased average daily feed intake and improved feed efficiency. However, pigs fed diets containing ground corn germ meal had similar gain and feed efficiency as those fed the corn-soyb...
