Reed-Solomon codes are indeed an elegant illustration of a very practical application of abstract algebra. An interesting
discovery was the fact that Euclid’s algorithm for finding greatest common divisors of polynomials, could be used for decoding
these codes. In this article we explain this connection.

This study examines associations between childhood maltreatment and developmental trajectories of sexual risk behaviors (SRBs) in a sample of 882 sexually active adolescent girls, predominantly Hispanic or Black, assessed every 6 months between 13 and 23 years. Latent profile analyses revealed four distinct maltreatment profiles: Low Maltreatment (76%), Moderate Emotional Neglect Only (15%), Severe Physical/Emotional Abuse (3%), and Severe Sexual Abuse (6%). Multilevel growth analyses showed the Moderate Emotional Neglect Only and Severe Sexual Abuse profiles exhibited more SRBs starting in late adolescence, and the Severe Sexual Abuse profile also exhibited a faster increase than the Low Maltreatment profile. Understanding heterogeneity within maltreated populations may have important implications for healthy sexual development. 相似文献

The World Wide Web has been growing in leaps and bounds. Studies have indicated that this massive distributed system can benefit greatly by making use of appropriate caching methods. Intelligent Web caching can lessen the burden on Web servers, improves its performance and at the same time reduces the network traffic. 相似文献

This paper uses regression analysis to test if the universities performing less well according to Shanghai Jiao Tong University’s world universities league tables are able to catch up with the top performers, and to identify national and institutional factors that could affect this catching up process. We have constructed a dataset of 461 universities across 41 countries. We found consistent evidence of a moderate degree of catching up, especially amongst non-US universities. Larger universities as well as universities located in English speaking countries not only perform better on average, but also catch up more over 2003–2009. Universities located in lower income countries are also catching up more. The performance of private universities, as compared to that of public universities, varies substantially between the US and the other countries. 相似文献

The serum lipid classes in 75 pregnant women (25 in each trimester) and 25 matched controls were investigated. The lipid classes
studied were very low density lipoproteins (VLDLc), low density lipoproteins (LDLc), high density lipoproteins (HDLc), total
triacylglycerols (Tg), phospholipids (PL) and total cholesterol (Tc). It was found that there is increase in HDLc during first
trimester followed by decrease during second and third trimesters. All other lipid classed including Tc and PL showed a progressive
increase. Analysis of data showed that Tc/HDLc ratio has an increasing trend with parity. LDLc/HDLc also showed similar correlation.
The results of our study indicates that there is likely to be increased risk for CHD in multiparous women as predicted from
serum lipid parameters. 相似文献

Fascinating and grand, with curious beaks and breeding habits, hornbills are a naturalist’s delight. In forest types ranging from open savannah to rainforest across Africa and Asia, they occupy the pride of place among birds and play a pivotal role as mutualistic frugivores and seed dispersers of various trees. Due to the impact of humans on hornbills and their habitats, most species are now endangered. Fortunately, there has been some success in recent conservation efforts to save these magnificent forest flagships. 相似文献
