Seismic isolation is a method to reduce the destructive effects of earthquakes on a structure in which the structure is separated from its foundation by devices called seismic isolators. As a result, the horizontal movements of the earthquake transmitted to the structure are reduced. The seismic isolation is used for both newly constructed structures as well as for retrofitting the existing bui...

Species are separated by reproductive isolation as well as by more 'ordinary' differences in morphology and behavior that play no necessary role in blocking gene flow. Although a great deal is now known about the genetics of reproductive isolation, we are only beginning to understand the genetic basis of ordinary phenotypic differences between species. I review what is known about the number of...

Nevertheless, only in the past few years has it been demonstrated that minimally invasive thoracic surgery improves outcomes compared with standard thoracotomy. However, one of the key elements for the success of these techniques is excellent lung isolation that allows optimal surgical visualization. A poorly collapsed lung leads to complications, prolongs surgical time, and mitigates the overa...

Exosomes are one type of membrane vesicles secreted into extracellular space by most types of cells. In addition to performing many biological functions particularly in cell-cell communication, cumulative evidence has suggested that several biological entities in exosomes like proteins and microRNAs are closely associated with the pathogenesis of most human malignancies and they may serve as in...

The general purpose computer has become pervasive and is supporting an increasing number of functions, including music, video, gaming, communications, banking, business, process control, and critical in frastructure. The use of a single computer for mult iple functions, and the interconnection of mult iple computers through a common network have reduced the isolation that protected such functio...
