We demonstrate that charge transport through a CMOS-compatible molecular electronic device is dominated by one of two different transport regimes depending on
A Bloom filter is a space-efficient data structure used for probabilistic set membership testing. When testing an object for set membership, a Bloom filter may
Cyber-physical systems feature a tight combination of a system's computational and physical elements. Understanding how to assess and design trustworthiness
The term trust has had a well understood definition for centuries. However after e-trust came along, and then cloud, where e-trust is not sufficient due to the

High-energy-resolution quasielastic neutron scattering on three complementary spectrometers has been used to investigate molecular diffusive motion in solid
Hildenbrand and coworkers have shown recently that the vapor above solid ammonium nitrate includes molecules of NH4NO3, not only NH3 and HNO3 as previously

We studied the contact properties of different metals to flexible optically-transparent single-walled carbon nanotube (SWCNTs) films. The SWCNT films are
In this paper we review statistical models that describe measurements from a multiple-method study such as in the development of a reference material. We also
The effects of an Ar ion assist beam during Al film growth by electron beam evaporation on the film composition, microstructure, and texture were assessed in
