Therefore, it is difficult to examine the operational conditions and accurately report the benefits of toll facilities to the public in terms they can...

Many problems from mathematics and engineering can be described in terms of reconstruction from geometric information. Reconstruction is the algorithmic problem of combining the results of measurements of some aspect of a physical or mathematical object to obtain desired information about the object. In this chapter, we consider three different classes of geometric reconstruction problems. In S...

Composite restoration materials have been in use for more than two decades as an aesthetic alternative to metal restorations in the posterior region, which bears a great deal of the masticatory load, with increasing frequency in recent years (Kelsey et al, 2000). The early clinical data on the posterior region, gathered in the early 1980s, was not encouraging, primarily due to insufficient mech...

Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GIST has been shown to over-express c-KIT (CD117), the receptor tyrosine kinase. Imatinib (STI571 or Glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to treat GIST. In this study we have...
