Three-dimensional electron microscopy (3D-EM) is a powerful technology for imaging macromolecular complexes. Through a process known as singleparticle reconstruction, tens of thousands of separate images of a complex of interest are used to arrive at a single resolved structure. Although this method works sufficiently well for rigid macromolecular complexes, conformationally flexible complexes ...

curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...

The information presented in this article is intended to make the reader aware of the most current research on the topic of flexibility and to make some practical suggestions for planning effective programs for developing flexibility in athletes. Though additional research needs to be done, we have enough knowledge to plan sound programs for reducing the incidence of injury and for promoting op...

flexibility as an ability to respond to changing circumstances is one of the vital characteristics of the natural and built environment. during the contemporary era, diversity of methods relating the architectural flexibility execution are suggested. but along with contemporary conceptual approaches toward pluralism and uncertainty, it seems that the multiplicity of approaches toward flexibilit...
