A key feature for infrastructures providing coordination services is the ability to define the behaviour of coordination abstractions according to the requirements identified at design-time. We take as a representative for this scenario the logic-based language ReSpecT (Reaction Specification Tuples), used to program the reactive behaviour of tuple centres. ReSpecT specifications are at the cor...

Studying the correlation between various stock and selecting risk of optimal portfolio are key topics current research. In macro field, it is a further problem with delving into in different markets. The researchers found that copula function can break restrictions traditional normal hypothesis linear correlation, which has significant advantage studying market to choose portfolio. This study e...

The evolution of neuroendocrine mechanisms governing sex-typical behaviour is poorly understood. An outstanding animal model is the whiptail lizard (Cnemidophorus) because both the ancestral and descendent species still exist. The ancestral little striped whiptail, Cnemidophorus inornatus, consists of males and females, which exhibit sex-specific mating behaviours. The descendent desert grassla...
