Escherynes: Belt-Shaped Carbon Allotropes

January 1, 2001
Author(s)
Ernesto Estrada, Yamil Simon
The discoveries of fullerenes, carbon nanotubes and graphene have increased dramatically the research interests on all-carbon materials. Carbon-based materials have found applications in nanotechnology, material sciences, electronics, optic and

Evaluation by Highly Relevant Documents

January 1, 2001
Author(s)
Ellen M. Voorhees
Given the size of the web, the search engine industry has argued that engines should be evaluated by their ability to retrieve highlyrelevant pages rather than all possible relevant pages. To explore the role highly relevant documents play in retrieval

Evaluation of Load Cells for Legal Metrology at NIST

January 1, 2001
Author(s)
Kevin L. Chesnutwood
Load cells for use in legal metrology issues are evaluated in accordance with the National Type Evaluation Program (NTEP) and the International Organization of Legal Metrology (OIML). An overview of the role played by the National Institute of Standards

Evolution of the Shapes of InAs and InGaAs Quantum Dots

January 1, 2001
Author(s)
Richard P. Mirin, Alexana Roshko, M. van der Puijl, Andrew G. Norman
The exact shape of self-assembled quantum dots is still a controversial subject in the literature, despite the fact that this knowledge is of paramount importance for modeling the energy levels and electron wavefunctions in the quantum dots. We will

Experimental Violation of Bell's Inequalities with Efficient Detection

January 1, 2001
Author(s)
M A. Rowe, D Kielpinski, V Meyer, C A. Sackett, Wayne M. Itano, C Monroe, David J. Wineland
Local realism is the idea that objects have definite properties whether or not they are measured, and that measurements of these properties are not affected by events taking place sufficiently far away. Einstein, Podolsky and Rosen used these reasonable

Extreme Ultraviolet Metrology at SURF III

January 1, 2001
Author(s)
Charles S. Tarrio, Robert E. Vest, S Grantham, Thomas B. Lucatorto
The last two decades have seen the development normal-incidence multiplayer mirrors and semiconductor photodiodes for extreme ultraviolet (EUV) radiation. Applications such as in astrophysics, lithography, and plasma physics, require precise calibrations

Ferrite Ceramics at Microwave Frequencies

January 1, 2001
Author(s)
Richard G. Geyer
Ferrite ceramics are widely used in microwave devices to control transmission path, frequency, amplitude, and phase of microwave signals. Accurate dielectric and magnetic property measurements at the operational frequency and temperature ranges are needed
