Taking a subsea collet connector as an example, the contact characteristics of sealing structure under thermal–structural coupling were studied. Considering heat transfer problem in deep water, model seawater layer between structures was established, and relationship equivalent thermal conductivity, composite coefficient, temperature determined. The steady-state field distribution action intern...

The disturbances to an airframe’s sensors caused by the flexibility of the airframe is called structural coupling. Notch filters are currently used to attenuate the effect that the structural modes have on the aircraft’s inertial flight control sensors. However, this approach is becoming more problematic with modern combat aircraft. A complex model which is representative of an agile combat air...

Structural coupling is the disturbance to the aircraft’s inertial sensors caused by the flexibility in the airframe, and is particularly problematic for modern combat aircraft. The current solution uses a series of notch filters to remove the structural frequencies, but these introduce significant phase delays into the control loop. This paper presents some experimental and theoretical results ...

Understanding of human structural brain development has rapidly advanced in recent years, but remains fundamentally "localizational" in nature. Here, we use 376 longitudinally acquired structural brain scans from 108 typically developing adolescents to conduct the first study of coordinated anatomical change within the developing cortex. Correlation in rates of anatomical change was regionally ...

We report the first synthesis of a natural (±)-gnetulin and an unnatural analogue of (±)-gnemonol M by using the regioselective oxidative coupling reactions of 5-tert-butyl-isorhapontigenin as the key step. Both the effects of different enzyme-catalyzed systems on the structures of coupling products and structural transformations of coupling products in the presence of several Lewis acids were ...
