Characterization of Sub-Monolayer Contaminants at the Regrowth Interface in GaN Nanowires Grown by Selective-Area Molecular Beam Epitaxy

Crystals, 2018
While GaN nanowires (NWs) offer an attractive architecture for a variety of nanoscale optical, electronic, and mechanical devices, defects such as crystal polarity inversion domains (IDs) can limit device performance.

A close-up of a stone sample set in the NIST stone wall [PDF]

, 2017
The NIST stone wall was built using 2,352 stones from 47 US states and 320 from 16 foreign countries. The wall is approximately 12 m long, 4 m high, 0.6 m thick at the bottom, and 0.3 m at the top. The aim of the wall construction was to study the aging

Performance and Statistical Analysis of Stream ciphers in GSM Communications

Journal of Communications Software and Systems, 2020
For a stream cipher to be secure, the keystreamgenerated by it should be uniformly random with parameter 1/2.Statistical tests check whether the given sequence follow a certainprobability distribution.

Unifying scrambling, thermalization and entanglement through measurement of fidelity out-of-time-order correlators in the Dicke model

Nature Communications, 2019
The scrambling of quantum information in a many-body system leads to the emergence of statistical mechanics and chaotic behaviour. Here the authors establish quantitative relationships between experimentally-measureable correlators, the Rényi entropy and

The NIST HumanID Evaluation Framework

, 2003
The NIST HumanID Evaluation Framework, or HEF, is an effort to design, implement, and deploy standards for the robust and complete documentation of the biometric system evaluation process. The HEF leverages contemporary technologies, specifically XML, for the formal description of biometric tests.
