Response time is a key differentiation point among electronic commerce (e-commerce) applications. For many e-commerce applications, Web pages are created dynamically based on the current state of a business stored in database systems. To improve the response time, many e-commerce Web sites deploy caching solutions for acceleration of content delivery. There are multiple tiers in the content del...

Multi-File Caching issues arise in applications where a set of jobs are processed and each job requests one or more input files. A given job can only be started if all its input files are preloaded into a disk cache. Examples of applications where Multi-File caching may be required are scientific data mining, bit-sliced indexes, and analysis of sets of vertically partitioned files. The differen...

Web caching and prefetching are the most popular techniques that play a key role in improving the Web performance by keeping web objects that are likely to be visited in the near future closer to the client. Web caching can work independently or integrated with the web prefetching. The Web caching and prefetching can complement each other since the web caching exploits the temporal locality for...

We explore a new proxy-caching framework that exploits the query semantics of HTML forms. We identify a common class of form-based queries, and study two representative caching schemes for them within this framework: (i) traditional passive query caching, and (ii) active query caching, in which the proxy cache can service a request by evaluating a query over the contents of the cache. Results f...

Multi-tier architectures provide a means for building scalable distributed services. Caching is a classical technique for enhancing the performance of systems (e.g. database servers, or web servers). Although caching solutions have been successfully studied for individual tiers of multi-tier systems, if collectively applied, these solutions may violate the coherence of cached data. This paper p...

The top-pions(Π) and the top-Higgs(HTC) are the typical particles predicted by the topcolor-assisted technicolor (TC2) model and the observation of these particles can be regarded as the direct evidence of the TC2 model. In this paper, we study two pair production processes of these new particles, i.e., ee → HTCΠ 0 and ee → ΠΠ. The results show that the production rates are at the level of serv...

Caching is widely used to reduce network traffic and improve user experience. Traditionally caches store complete objects, but video files and the recent emergence of informationcentric networking have highlighted a need for understanding how partial caching could be beneficial. In partial caching, objects are divided into chunks which are cached either independently or by exploiting common pro...

We consider the problem of secretive coded caching in a shared cache setup where number users accessing particular xmlns:xlink="http://www.w3.org/1999/xlink">helper cache is more than one, and every user can access exactly one helper cache. In secretive caching, constraint xmlns:xlink="http...

Evolution of complex cognition in animals has been linked to complex social behaviour. One of the costs of sociality is increased competition for food which may be reduced by food caching, but cache theft may undermine the benefits of caching. In birds, sophisticated food-caching-related cognition has been demonstrated only for corvids and attributed to their highly social behaviour. Many non-c...
