Metrology Challenges in 3D NAND Flash Technical Development and Manufacturing

open access: yesJournal of Microelectronic Manufacturing, 2020
3D NAND technical development and manufacturing face many challenges to scale down their devices, and metrology stands out as much more difficult at each turn. Unlike planar NAND, 3D NAND has a three-dimensional vertical structure with high-aspect ratio.

A potential biomarker of cognitive impairment: The olfactory dysfunction and its genes expression

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1884-1897, December 2022., 2022
Abstract Objective Accumulation evidence has reported that olfactory impairment may be an essential clinical marker and predictor of mild cognitive impairment or Alzheimer's disease. Method Participants were enrolled in the population‐based, prospective study in Fuxin county, Liaoning province, China between 2019 and 2021.

Clinical utility of cerebrospinal fluid biomarkers measured by LUMIPULSE® system

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1898-1909, December 2022., 2022
Abstract Objectives Cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) are well‐established in research settings, but their use in routine clinical practice remains a largely unexploited potential. Here, we examined the relationship between CSF biomarkers, measured by a fully automated immunoassay platform, and brain β‐amyloid (Aβ ...

“A Guy ‘Does’ and You Don’t, They Do You Instead”: Young People’s Narratives of Gender and Sexuality in a Low-Income Context of South Africa

open access: yesSAGE Open, 2018
The intensive research focus on young people’s sexuality in relation to risk means that young people’s sexuality is often pathologized. We thus miss out on the day-to-day lived realities of how young people negotiate gender identity as well as sexuality ...

Vascular endothelial‐cadherin as a marker of endothelial injury in preclinical Alzheimer disease

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1926-1940, December 2022., 2022
Abstract Objective Endothelial dysfunction is an early and prevalent pathology in Alzheimer disease (AD). We here investigate the value of vascular endothelial‐cadherin (VEC) as a cerebrospinal fluid (CSF) marker of endothelial injury in preclinical AD.
