BACKGROUND Multi-detector computed tomography (MDCT) was used in order to assess the trabecular distribution of proximal femur and its relationship with hip fragility fractures. METHODS A total of 99 elderly women were scanned by MDCT including: 27 trochanteric hip fractures (group A), 40 femoral neck fractures (group B), and 32 non-fractures (group C). A mid-coronal MPR image of the proximal...

tetanus is caused by the tetanus neurotoxin (tent), a 150 kda single polypeptide molecule which is cleaved into active two-chain molecules composed of a 50 kda n-terminal light (l) and a 100 kda c-terminal heavy (h) chains. fragment c is further subdivided into two subdomains: the proximal hcn  subdomain and the extreme carboxy subdomain, hcc. hcc is considered as an immunodominant part of tent...

We show that given a type α of an adding machine, for a dense set of parameters s in the interval [ √ 2, 2], if f is the tent map with slope s, then the restriction of f to the closure of the orbit of the turning point is topologically conjugate to the adding machine map of type α.

In this paper we present an overview of the results concerning dynamics of a piecewise linear bimodal map. The organizing principles of the bifurcation structures in both regular and chaotic domains of the parameter space of the map are discussed. In addition to the previously reported structures, a family of regions closely related to the so-called U-sequence is described. The boundaries of di...
