        Hindwings of many lycaenid butterflies have a unique tail-like wing structure referred to as a false head, which actually mimics the antennae. False heads increase butterfly survival by directing predatory attacks towards the false heads thereby enhancing the chance of escape. In this study, using discrete character evolution models of European and American butterflies, we examined the co-evolutionary patterns between false head structures and two associated traits: a highly contrasting color patch neighboring the false head, and hindwing rubbing behaviors. The former is considered a eye-mimicking structure that enhances the effectiveness of false head, and latter generates the movement of false heads which likely increases the success of false head deception. Our findings demonstrate that false heads are ancestral states for both European and American lycaenids. Both contrasting colors and hindwing rubbing behaviors follow correlated evolution models, suggesting that these traits co-evolved in lycanid butterflies. However, specific evolutionray patterns differed between the two continents.

        Wind turbines are designed and analyzed using simulation tools capable of predicting the coupled dynamic loads and responses of the system. In this paper, an overview of the capabilities of a Computer-Aided Engineering (CAE) tool called FAST or Fatigue, Aerodynamic, Structures, and Turbulence in modeling wind turbines in different depths of water will be presented. Different offshore wind turbine support systems structures will be discussed. These support systems are classified into three categories according to the water depth, namely, shallow water, translational water and deep water depths. This paper will be focusing on the support structures used in translational and deep water depths only. This will also be focusing on incorporating hydrodynamic loading for multimember structures using FAST through its hydrodynamic loading module, Hydrodyn. Also, a quantitative comparison of th*e responses of different floating platforms will be tackled.
