The yellow pages service of GTE SuperPages enables Web users to flexibly search through liitings of 11 million businesses in over 17000 categories. To achieve the flexibility desired it uses an Information Retrieval (IR) engine to search through complex listing objects. The objects themselves are stored in an object database. The use of the IR engine enables us to create an index that spans all...

Animal behavior is often altruistic. In the frame of the theory of natural selection, altruism can only exist under specific conditions like kin selection or reciprocal cooperation. We show that reciprocal cooperation, which is generally invoked to explain non-kin altruism, requires very restrictive conditions to be stable. Some of these conditions are not met in many cases of altruism observed...

These comments are respectfully submitted both as to the Horizontal Merger Guidelines ("HMG") generally, and also to questions 1-10., 12-15. They show that as a litigation matter the current HMG must be replaced because they are dependent on the PNB presumption, which will be overruled under the Supreme Court's GTE Sylvania and later presumption cases, and that new merger guidelines (and antitr...

the mean fiber length of three beech trees (fagus orientalis l.) at the lower and higher points (1% and 75% tree height) of the stem at an intermediate altitude (500-1000m) in the caspian forests in sari region were 1.36 and 1.22mm respectively, close to the values in three trees at high altitude (1000-1500m), that were found to be 1.39 and 1.36 mm. the mean fiber lengths of the whole stem, usi...

History shows that problems that cause human confusion often lead to inventions to solve the problems, which then leads to exploitation of the invention, creating a confusion-invention-exploitation cycle. Robotics, which started as a new type of universal machine implemented with a computer controlled mechanism in the 1960’s, has progressed from an Age of Over-expectation (1960-86), a Time of N...

We consider a system with finite lifespan and single critical component that is subject to random failures. An age-based replacement policy applied preventively replace the before its failure. The components used for come from either weak population or strong population, referred as heterogeneity. However, true type unknown decision maker. By considering maker has belief on probability of havin...

Since real data is time-consuming and expensive to collect, label, and use, researchers have proposed approaches using synthetic variations for the tasks of signature verification, speaker authentication, handwriting recognition, keyword spotting, etc. However, the limitation of real data is particularly critical in the field of writer identification in that in forensics, enemies or criminals u...

Past research often found that older adults searched less in terms of browsing and generating keywords; few studies examined the processes and underlying mechanism that caused the age-related reduction on search. In the current study, 20 younger and older adults performed ill-defined search tasks with a search box we implemented. In addition to the age differences in the quantities of search, r...
