A non-linear Penner type interaction is introduced and studied in the random matrix model of homo-RNA. The asymptotics in length of the partition function is discussed for small and large N (size of matrix). The interaction doubles the coupling (v) between the bases and the dependence of the combinatoric factor on (v,N) is found. For small N , the effect of interaction changes the power law exp...

Ligands belonging to the transforming growth factor (TGF) superfamily have emerged as major regulators of a wide variety of developmental events, ranging from the earliest steps in germ layer patterning of the pre-gastrula embryo to tissue healing, regeneration and homeostasis in the adult. Recently, Caroline Hill and Bob Lechleider organized the third in a bi-annual series of FASEB meetings on...

and developing countries was recommended as the main topic of this year’s summit. Participants were encouraged to discuss differences in stroke etiology, subtypes, incidence, recurrence, risk factors, diagnosis, prevention, management and prognosis among countries and regions. Special emphasis was put on generalizing stroke education, increasing awareness of stroke warning signs among average p...
