Kinetic models are essential for studying complex behavior and properties of metabolism. However, a persistent hurdle for constructing these models is uncertainty in the kinetic properties of enzymes. Currently available methods for building kinetic models ...
Social networks such as Facebook and Twitter are privileged platforms for teenagers’ expression and information sharing. This study, based on a Big Data approach, aims to explore how persons under 18 years old “talk” about their mobility behaviors and aspi ...
Numerous research groups and other organizations collect data from popular data sources such as online social networks. This leads to the problem of data islands, wherein all this data is isolated and lying idly, without any use to the community at large. ...
