Memristive devices are electrical resistance switches that can retain a state of internal
resistance based on the history of applied voltage and current. These devices can store and …

Anyone who ever took an electronics laboratory class will be familiar with the fundamental
passive circuit elements: the resistor, the capacitor and the inductor. However, in 1971 Leon …

Nanoscale metal/oxide/metal switches have the potential to transform the market for
nonvolatile memory and could lead to novel forms of computing. However, progress has been …

Background Pulmonary hypertension is characterized by an increase in vascular tone or an
abnormal proliferation of muscle cells in the walls of small pulmonary arteries. Endothelin-1 …

The authors of the International Technology Roadmap for Semiconductors 1 —the industry
consensus set of goals established for advancing silicon integrated circuit technology—have …

Background— Given the central importance of nitric oxide (NO) in the development and
clinical course of cardiovascular diseases, we sought to determine whether the powerful …

Objective: To explore the role of endothelin-1, a potent endothelial-derived vasoconstrictor
peptide, in pulmonary hypertension, by measuring its concentration in arterial and venous …

Background Mesenchymal stromal cells (MSCs, “adult stem cells”) have been widely used
experimentally in a variety of clinical contexts. There is interest in using these cells in critical …

Metal and semiconductor oxides are ubiquitous electronic materials. Normally insulating,
oxides can change behavior under high electric fields—through'electroforming'or'breakdown'—…

Molecular electronics offer an alternative pathway to construct nanoscale circuits in which the
critical dimension is naturally associated with molecular sizes. We describe the fabrication …
