The search for ways to select for improved beef cow efficiency has become the holy grail of the beef cattle seedstock industry. Increases in beef production have often been possible due to enhancements in the reproduction indexes (e.g. calving frequency, age at first calving, calving interval), nutrition concepts (e.g. strategic supplementation, type of forage as well as quantity and quality), ...

The interest in this research is on determining preand post-...

DHT systems are structured overlay networks capable of using P2P resources as a scalable storage platform for very large data applications. However, their efficiency expects a level of uniformity in the association of data to index keys that is often not present in inverted indexes. Index data tends to follow non-uniform distributions, often power law distributions, creating intense local stora...

This paper proposes a new methodology to build composite coincident and leading indexes. Based on a formal definition that requires that the first differences of the leading index is the best linear predictor of the first differences of the coincident index, it is shown that the notion of polynomial serial correlation common features can be used to build these composite variables. Concepts and ...

Prais (1958) showed that the standard CPI computed by most statistical agencies can be interpreted as a weighted average of household price indexes, where the weight of each household is determined by its total expenditures. In this paper, we decompose the difference between the standard CPI and a democratically weighted index (i.e., the CPI plutocratic gap) as the product of expenditure inequa...

The present study investigated and analyzed the clinical impact of sublobectomy on pulmonary functions.Changes in pulmonary function before and after sublobectomy were compared to the changes after lobectomy.Changes in the pulmonary function before and after sublobectomy and lobectomy did not exhibit remarkable differences in long-term effects. Surgery-related indexes of the sublobectomy group ...

Based on social network perspective, we developed a model about the knowledge sharing of communities of practice (CoPs), analyzed the knowledge sharing of CoPs from the view of the network density, network centrality, network structure. And we found out that only the above indexes are kept in appropriately level can stimulate the knowledge sharing in CoPs. The strong ties contribute to the tran...

A secure index is a data structure that allows a querier with a " trapdoor " for a word x to test in O(1) time only if the index contains x; The index reveals no information about its contents without valid trapdoors, and trapdoors can only be generated with a secret key. Secure indexes are a natural extension of the problem of constructing data structures with privacy guarantees such as those ...
