Graph representations of brain connectivity have attracted a lot of recent interest, but existing methods for dividing such graphs into connected subnetworks have a number of limitations in the context of neuroimaging. This is an important problem because most cognitive functions would be expected to involve some but not all brain regions. In this paper we outline a simple approach for decompos...

RECEIVED NJ COMMISSION ON SPINAL CORD RESEARCH As stated in the proposal, the broad, long-term objective of this research is to develop a force-actuating, implantable biomaterial to spur regeneration and growth of the spinal cord. Two general tissue engineering strategies have been employed in attempt to restore spinal cord function following trauma. The first and most prevalent is the developm...

Principal curves are smooth one-dimensional curves that pass through the middle of a p-dimensional data set, providing a nonlinear summary of the data. They are nonparametric, and their shape is suggested by the data. The algorithm for constructing principal curves starts with some prior summary, such as the usual principal-component li e. The curve in each successive iteration is a smooth or l...

Renovascular hypertension has its experimental counterpart in the two-kidney, one clip model (Goldblatt hypertension). From the study of this model, a general pathophysiological scheme has evolved suggesting that temporal stages in the development and maintenance of hypertension are regulated by complicated hormonal and neural interrelations. The central roles played by the renin-angiotensin sy...

• Inmates continue to use drugs in prison. The most common identified avenue of trafficking remains the visitor reception area, by mouth transfer during contact visits. More drugs, syringes and other implements are seized in prison than at the 'visitor' barrier. • Qualitative data suggest that cannabis and pharmaceuticals are the most commonly used or available drugs. Urinalysis data show some ...
