1 This work was done in collaboration with Mitsubishi Electric Research Laboratories in Cambridge, Massachusetts ABSTRACT People naturally perform multimodal interactions in everyday real world settings, as they collaborate over large visual surfaces such as paper maps on walls and tables. While a new generation of research technologies now supports co-located collaboration, they do not yet dir...

 A spider angioma or naevus is a type of telangiectasis found slightly beneath skin surface, often containing central arteriole and many small vessels which radiate outwards like spider's web. Applying pressure to center lesion leads fading lesion. Spider common presentation liver cirrhosis, especially alcoholic cirrhosis. angiomas are only in distribution superior vena cava...

Typical characteristics are short duration; pain occurring on one side of head, including eye area; and extreme intensity.[1] Pathophysiology of CH is not fully understood.

AGAMOUS (AG) is an Arabidopsis MADS box gene required for the normal development of the interna1 two whorls of the flower. AG RNA accumulates in distinct patterns early and late in flower development, and several genes have been identified as regulators of AG gene expression based on altered AG RNA accumulation in mutants. To understand AG regulatory circuits, we are now identifying cis regulat...
