Relationships have been an essential component of OO design since the 90s, yet mainstream OO languages still do not support first-class relationships. Most programs implement relationships in an ad-hoc fashion which results in unnecessarily complex code. We examine the requirements for a good first-class relationship abstraction and compare this with existing work. These requirements serve both...

Object-oriented (OO) software engineering techniques are often used with programming languages, but they also apply to relational databases. OO techniques are not only helpful for determining database structure, but also for designing stored procedure code. In fact, we were surprised by the magnitude of the stored procedure benefits. OO techniques boost development productivity as well as the q...

BACKGROUND Olive oil (OO) consumption is associated with cardiovascular disease prevention because of both its oleic acid and phenolic contents. The capacity of OO phenolics to protect against low-density lipoprotein (LDL) oxidation is the basis for a health claim by the European Food Safety Authority. Proteomic biomarkers enable an early, presymptomatic diagnosis of disease, which makes them i...

Turn-oo transients in current-modulated weakly-index-guided vertical-cavity surface-emitting lasers (VCSELs) are analyzed by using a model that takes into account all the transverse modes supported by the waveguide. Turn-oo transients strength is maximum for the current at which the VCSEL enters the multi-transverse-mode regime. Their strength signiicatively decreases for the multi-mode regime ...
