I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties [PDF]
, 2016 The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains roughly as in the L-mode ...

Narrow Band Imaging: Technology Basis and Research and Development History [PDF]
Clinical Endoscopy, 2015 The first launch of narrow band imaging (NBI) was in 2005. Since then, in most countries where gastrointestinal endoscopies are performed, NBI is the most commonly used optical digital method of performing image-enhanced endoscopy.

Impact of Narrow Band Imaging in Pre-Operative Assessment of Suspicious Oral Cavity Lesions: A Systematic Review [PDF]
Iranian Journal of Otorhinolaryngology, 2021 Introduction: Narrow band imaging (NBI) is a powerful tool that allows visualizing the mucosal and submucosal vasculature. Among the available diagnostic techniques, NBI is one of the most valid for early detection of oral squamous cell carcinoma (OSCC).
