In current structural steel design specifications, the local buckling of cross-sections is typically treated on an element-by-element basis, with boundary conditions along adjoined longitudinal edges individual plates assumed to be simply-supported. reality, buckle locally as a whole and plate elements interact. As result, critical isolated (i.e. that lowest elastic stress) lie between lower up...

Several independent observations have suggested that the catastrophe transition in microtubules is not a first-order process, as is usually assumed. Recent in vitro observations by Gardner et al. [M. K. Gardner et al., Cell 147, 1092 (2011)] showed that microtubule catastrophe takes place via multiple steps and the frequency increases with the age of the filament. Here we investigate, via numer...

1. Proceedings from the Gatherings for Gardner Conference. Edited by a variety of people. To show their appreciation for Martin Gardner there have been several Gatherings for Gardner conferences which are gatherings of mathematicians, puzzlers, and magicians. The rst two gatherings were in 1993 and 1995. They had no proceedings. However, the ones since 1998 have. We give reviews of the six proc...

Tetraploidy was increased in skin fibroblast cultures grown in the laboratory at the same time under the same conditions and derived from 2 probands with the Gardner syndrome and 9 affected members of one family as compared to that occurring in cultures from 5 relatives by marriage and 10 normals. Tetraploidy was present at the first subculture (2 weeks after the initial biopsy was cultured), a...

The current paradigm for HIV and drug prevention research is going through a rapid expansion that includes the use of social network theory, methods, and practical implications. Most epidemiologic and prevention research on HIV/AIDS transmission, substance abuse, and high risk behaviors has been conducted in urban settings targeting injection drug users (Castro, Valdiserri, & Curran, 1992), gay...

Gardner=s syndrome refers to a group of children born with familial adenomatous (multiple) polyposis and significant extracolonic manifestations. Familial adenomatous polyposis is an autosomal dominant disorder originating from a germline alteration of the adenomatous polyposis coli gene in the long arm of chromosome 5. The most significant extracolonic manifestation of Gardner=s syndrome consi...
