Roads are pervasive features of modern landscapes and have major impacts on air, land, and water quality. The United States has >6.2 million km of public roads used by >200 million vehicles (National Research Council [NRC]1997). Road corridors (road plus maintained parallel strips) cover 1% of the United States (NRC 1997) but their direct environmental impacts extend to 20% of the land surface ...

In the present work, we study the properties of biological networks by applying analogous notions of fundamental concepts in Riemannian geometry and optimal mass transport to discrete networks described by weighted graphs. Specifically, we employ possible generalizations of the notion of Ricci curvature on Riemannian manifold to discrete spaces in order to infer certain robustness properties of...

Vasoactive intestinal polypeptide (VIP) and pituitary adenyl-ate cyclase activating polypeptide (PACAP) belong to a family of regulatory peptides which are widely expressed in the body. Their widespread distribution is correlated with their involvement in a large variety of biological activities. Both peptides display a remarkable amino acid sequence homology. They exert their biological effect...
