Stationarity and Persistence in the GARCH(1,1) Model
This paper establishes necessary and sufficient conditions for the stationarity and ergodicity of the GARCH(l.l) process. As a special case, it is shown that the IGARCH(1,1) pro...
Morphogenesis of the Polarized Epithelial Cell Phenotype
Polarized epithelial cells play fundamental roles in the ontogeny and function of a variety of tissues and organs in mammals. The morphogenesis of a sheet of polarized epithelia...
Alzheimer's disease-affected brain: Presence of oligomeric Aβ ligands (ADDLs) suggests a molecular basis for reversible memory loss
A molecular basis for memory failure in Alzheimer's disease (AD) has been recently hypothesized, in which a significant role is attributed to small, soluble oligomers of amyloid...
Charge Transfer on the Nanoscale: Current Status
This is the report of a DOE-sponsored workshop organized to discuss the status of our understanding of charge-transfer processes on the nanoscale and to identify research and ot...
Generic knowledge strategies in the U.S. pharmaceutical industry
Abstract The purpose of this study is to identify groups of firms with similar generic knowledge strategies, determine how these strategies change over time, and compare profit ...
Magnetic, transport, and optical properties of monolayer copper oxides
The authors review the results of a wide variety of experiments on materials such as ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4}$ and ${\mathrm{Nd}}_{2}{\mathrm{CuO}}_{4}$ that contain...
Signaling and Circuitry of Multiple MAPK Pathways Revealed by a Matrix of Global Gene Expression Profiles
Genome-wide transcript profiling was used to monitor signal transduction during yeast pheromone response. Genetic manipulations allowed analysis of changes in gene expression un...
Nitric oxide and cGMP cause vasorelaxation by activation of a charybdotoxin-sensitive K channel by cGMP-dependent protein kinase.
Nitric oxide (NO)-induced relaxation is associated with increased levels of cGMP in vascular smooth muscle cells. However, the mechanism by which cGMP causes relaxation is unkno...
