Yes, such linkages have been around for years.
"Linkages have been made in devices that have been used in different continents," said one forensic expert involved in the intelligence effort.
Peaks for cis amide linkages have been identified for selected nylons and model compounds by 1H, 13C and 15N observation.
An abundance of such mind-brain linkages have been established using standard neuropsychological and brain-imaging procedures.
Traditional approaches for establishing such linkages have relied largely on computationally expensive numerical simulation tools (e.g., the finite element models).
Many studies aimed to generalize Jitterbug-like linkages have been published, however a complete classification does not yet exist.
24-Membered macrocycles with chalcone subunits and isobutenyl linkages have been formed through a mixed aldol condensation.
Official reports, survey, medical records review, and multi-source data linkages have all been used to detect and classify maltreatment (Fluke et al. 2008).
Recently, linkages have formed between futures studies and a growing research field on sustainable transitions (see Technology Forecasting and Social Change 2012, 79/6, Special Section).
In particular, this paper assumes that some common innovation linkages have existed across the East Asian region for over 20 years (1980 2000).
In the last decades, with global networking, with social media, digitalization of the economy, linkages have become much closer, exchange much more rapid.
