Previous work in our laboratory has shown that microvascular pericytes sort muscle and nonmuscle actin isoforms into discrete cytoplasmic domains (Herman, I. M., and P. A. DAmore. 1985. J. Cell Biol. 101:43-52; DeNofrio, D., T. C. Hoock, and I. M. Herman. J. Cell. Biol. 109:191-202). Specifically, muscle (ix-smooth) actin is present on the stress fibers while nonmuscle actins (/3 and 3') are lo...
Dipartimento di Ingegneria Elettrica e delle Tecnologie dell’Informazione Doctor of Philosophy A Model-Driven Approach to Quantitative Analysis of Critical Systems by Roberto Nardone Critical systems are present in our daily life and affect many aspects providing essential support to several human activities; they are employed in several application domains, providing support to economic activi...
InP thin films have been grown on InP/Si substrate by epitaxial lateral overgrowth (ELOG). The nature, origin and filtering of extended defects in ELOG layers grown from single and double openings in SiO2 mask have been investigated. Whereas ELOG layers grown from double openings occasionally exhibit threading dislocations (TDs) at certain points of coalescence, TDs are completely absent in ELO...
We have fabricated a series of thin (~50 nm) erbium-doped (by ion implantation) silicon-rich oxide films in the configuration that mitigates previously proposed mechanisms for loss of light emission capability of erbium ions. By combining the methods of optical, structural and electrical analysis, we identify the erbium ion clustering as a driving mechanism to low optical performance of this ma...
Photonic signal processing requires efficient on-chip light sources with higher modulation bandwidths. Today’s conventional fastest semiconductor diode lasers exhibit modulation speeds only on the order of a few tens of GHz due to gain compression effects and parasitic electrical capacitances. Here we theoretically show an electrically-driven carbon nanotube (CNT)-based laser utilizing strong l...
