OCTA-Derived Retinal Biomarkers and Infarct Topography Improve Etiologic Classification of Recent Single Subcortical Infarction: A Nomogram Model. [PDF]

open access: yesCNS Neurosci Ther
A nomogram integrating reduced superficial vascular complex density on OCTA with proximal and multi‐slice infarct topography improves differentiation of branch atheromatous disease (BAD) from CSVD‐related lacunar infarction (CSVD‐related LI) in recent single subcortical infarction (RSSI).

A New Algorithm for Indoor RSSI Radio Map Reconstruction

open access: yesIEEE Access, 2018
This paper proposes an empirical model of RSSI radio map in order to improve the indoor positioning accuracy of Wi-Fi RSSI. First, the signal feature point in RSSI space is proposed based on the indoor RSSI map, which is similar to the geomorphic feature

Plasma GFAP and NLRP3 Associate with Cognitive Impairment After Recent Small Subcortical Infarct via Periventricular White Matter Hyperintensity [PDF]

open access: yesCNS Neurosci Ther
Ischemic stroke, recent small subcortical infarcts, induce systemic inflammation, leading to elevated levels of circulating inflammatory proteins. Through blood–brain barrier disruption, these proteins may gain access to the central nervous system and amplify microvascular injury and white matter degeneration, which directly and indirectly lead to ...
