Cell biology has never been more diverse. Cell biologists now increasingly cross the boundaries of traditionally defined fields, they use rapidly changing technology, and they work evermore in interdisciplinary teams. These new ways of doing science require new ways of communicating it. The JCB continuously evaluates and updates its publication formats and guidelines. To provide the best possib...

This paper describes a novel way to represent the 32 crystallographic point groups for use in a classroom environment. The groups are rendered using a 3D ray-tracing package and a variety of movie and still image formats are made available in the public domain.

The underlying problem confronting us in this paper is the determination of precise upper bounds for the moduli of the coefficients in these normalized expansions at » for functions in the classes S and T. This problem for the first two coefficients in each class has already been solved. We note first that since 4> and / are inverse, ai= —bx and a2= —b2, so for these two cases, discussion of on...

2. QUESTIONS FOR DISCUSSION 2.1 Middleware We built the LTDL using the University of Michigan’s DLXS middleware and the XPAT search engine. Some modifications were made to the software to optimize image displays and other features. The implementation we used – bibliographic class – does not readily accommodate searching text versions of document image files. We are faced with either a major upg...
