Poly-, Quasi- and Rank-One Convexity in Applied Mechanics


Book Description

Generalized convexity conditions play a major role in many modern mechanical applications. They serve as the basis for existence proofs and allow for the design of advanced algorithms. Moreover, understanding these convexity conditions helps in deriving reliable mechanical models. The book summarizes the well established as well as the newest results in the field of poly-, quasi and rank-one convexity. Special emphasis is put on the construction of anisotropic polyconvex energy functions with applications to biomechanics and thin shells. In addition, phase transitions with interfacial energy and the relaxation of nematic elastomers are discussed.




Modern Optics, Electronics and High Precision Techniques in Cell Biology


Book Description

In spite of tremendous scientific progress over the past years, cell biologists do not yet understand the fundamental processes that determine the life cy cle of a cell. Such are: cell movement and cell spreading, cell division, cell communication, cell signaling, cell regeneration and cell death. Biochemistry has enabled us to recognize and to isolate an overwhelming number of new proteins. In vitro assays and the reinjection of proteins into cells and tissues have provided insights into molecular functions and cellular mechanisms. The renaissance of the genetic approach by applying restriction enzymes and vectors, PCR and antisense technology has enabled us to overexpress certain cellular products, to make altered constructs of cell components or to create "knock-out" mutants that entirely lack the factor of interest. Amazingly en ough, all these molecular toys have led to a stream of information but not, in a comparable degree, to a better understanding. Has the puzzle become too complex to get solved; or are the windows too small that we are looking through? As an attempt to answer both questions, the aim of the present mono graph Modern Optics, Electronics and High Precision Techniques in Cell Biol ogy is first to provide cell and molecular biologists with a whole new scope of easily applicable techniques including brand-new optical, biophysical, physicochemical and biosensoric devices. Secondly, these newly developed techniques allow us to look at cells and biological systems as a whole.
