In this paper, we consider the problem of querying multimedia presentations based on content information. We believe that presentations should become an integral part of multimedia database systems, and users should be able to store, query, and possibly manipulate multimedia presentations using a single database management system software.

An essential aspect of tooth tissue engineering is the identification of suitable scaffolding materials to support cell growth and tissue regeneration. Treated dentin matrix (TDM) from a rat has recently been shown to be a suitable scaffold for rat dentin regeneration. However, due to species-specific differences, it remains unclear whether a similar(More)
Although recent studies have found that HO-1 plays an important role in neuronal survival, little is known about the precise mechanisms occurring during cerebral ischemia/reperfusion (I/R). Therefore, the aim of this study was to investigate the neuroprotective mechanisms of HO-1 against ischemic brain injury induced by cerebral I/R and to explore whether(More)
Increasing evidence suggests that homeodomain-leucine zipper I (HD-Zip) I transcription factors play important roles in abiotic stress responses, but no HD-Zip I proteins have been reported in maize. Here, a drought-induced HD-Zip I gene, Zmhdz10, was isolated from maize and characterized for its role in stress responses. Real-time quantitative PCR showed(More)

One of the critical deficiencies of SQL is lack of support for n-dimensional array-based computations which are frequent in OLAP environments. Relational OLAP (ROLAP) applications have to emulate them using joins, recently introduced SQL Window Functions [18] and complex and inefficient CASE expressions. The designated place in SQL for specifying(More)
OBJECTIVE We hypothesize that not all of the traditional risk factors of impacting mortality rate in commonly traumatic populations with posttraumatic acute respiratory distress syndrome (ARDS) are independently associated with those patient populations identified with severe multiple trauma. Rather, we postulate that there may exist significantly different(More)
