Virus surveys of commercial vineyards show value of planting certified vines [PDF]
California Agriculture, 2019 Viruses are of great concern in vineyards. They cost the California wine grape industry as much as $91,661 per acre over the life of a vineyard, according to a 2015 economic study of the North Coast wine-growing region.

A new quantum random number generator certified by value indefiniteness [PDF]
Theoretical Computer Science, 2021 In this paper we propose a new ternary QRNG based on measuring located value indefinite observables with probabilities $1/4, 1/2,1/4$ and prove that every sequence generated is maximally unpredictable, 3-bi-immune (a stronger form of bi-immunity), and its prefixes are Borel normal.

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.

Preparation of Perlite Reference Material for Compositional Analysis
Yankuang ceshi, 2023 BACKGROUND Perlite is a vitreous rock formed by rapid cooling of volcanic eruptive acidic lava. It is a very important non-metallic mineral, because of its brittleness, light weight, rapid expansion on heating, and other excellent characteristics, and is

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.
