A quantum random number generator certified by value indefiniteness [PDF]
Mathematical Structures in Computer Science, 2014 In this paper we propose a quantum random number generator (QRNG) that uses an entangled photon pair in a Bell singlet state and is certified explicitly by value indefiniteness. While ‘true randomness’ is a mathematical impossibility, the certification by value indefiniteness ensures that the quantum random bits are incomputable in the strongest sense.

Value creation for tenants in environmentally certified buildings [PDF]
Building Research & Information, 2016 Previous research suggests that environmental certification (EC) affects rental rates in non-residential buildings, but there is still little understanding of how tenants differentiate such buildings from those without EC. This paper examines whether and how tenants perceive value creation in EC premises in Sweden.

Preparation of Reference Materials for Carbon and Nitrogen Isotopes of Organic Materials
Yankuang ceshi, 2020 OBJECTIVES The carbon and nitrogen isotope reference materials used by laboratories and researchers are generally obtained by the International Atomic Energy Agency (IAEA). However, in recent years, with the widespread use of carbon and nitrogen isotopes

The perceived value of certification by certified perioperative nurses
Nursing Outlook, 2003 We conducted this study to determine the perceived value of certification in perioperative nursing. Following development and pilot-testing, we mailed the 18-item Likert-type instrument, the Perceived Value of Certification Tool (PVCT), to a sample of 2750 perioperative nurses who had earned the CNOR or CRNFA credential or both. A total of 1398 surveys
