MRI is a useful method for the evaluation of malignant invasion of the nipple-areolar complex. Nipple-areolar complex enhancement with thickening could suggest the possibility of nipple involvement.

The presence of a lesion with a spiculated margin may predict a relatively good prognosis, and the presence of a lesion with rim enhancement may predict a relatively poor prognosis.

Use of both scintigraphy and US results in a more complete depiction of neonatal congenital hypothyroidism than either test alone.

Abstract. In this paper we consider bi-criteria geometric optimization problems, in particular, the minimum diameter minimum cost spanning tree problem and the minimum radius minimum cost spanning tree problem for a set of points in the plane. The former problem is to construct a minimum diameter spanning tree among all possible minimum cost spanning trees, while the latter is to construct a minimum radius spanning tree among all possible minimum cost spanning trees. The graphtheoretic minimum diameter minimum cost spanning tree (MDMCST) problem and the minimum radius minimum cost spanning tree (MRM-CST) problem have been shown to be NP-hard. We will show that the geometric version of these two problems, GMDMCST problem and GMRMCST problem are also NP-hard. We also give two heuristic algorithms, one MCST-based and the other MDST-based for the GMDMCST problem and present some experimental results.

Residential networks enable to control and composite functions on dinerent home appliance, but the diversiiy of home appliances brings various kinds of middleware into a single house. Because only one kind of middleware is not used, home appliances on different middleware networks can't use one another functions on condition that they are physically connected. This paper proposes the generic framework for interoperability in heterogeneous middleware networks and presents residential networks constituted by UPnP and Havi networks as example.
