Using functional principal component analysis (FPCA) to quantify sitting patterns derived from wearable sensors

International Journal of Behavioral Nutrition and Physical Activity
Background Sedentary behavior (SB) is a recognized risk factor for many chronic diseases. ActiGraph and activPAL are two commonly used wearable accelerometers in SB research. The former measures body movement and the latter measures body posture.

Mechanical Thrombectomy of the Fetal Posterior Cerebral Artery

Stroke: Vascular and Interventional Neurology, 2021
Background Fetal posterior cerebral artery (FPCA) occlusion is a rare but potentially disabling cause of stroke. While endovascular treatment is established for acute large vessel occlusion stroke, FPCA occlusions were excluded from acute ischemic stroke

The Fetal Type of Posterior Cerebral Artery

Medicina, 2023
Background and Objectives: Anatomical variations of the arterial circle of Willis (cW) are common. A posterior cerebral artery (PCA) fed mostly or exclusively from the internal carotid artery is a fetal PCA (FPCA), partial (p-FPCA), or full/complete (f ...

Abstract 1122‐000207: Mechanical Thrombectomy of the Fetal Posterior Cerebral Artery

Stroke: Vascular and Interventional Neurology, 2021
Introduction: Fetal posterior cerebral artery (FPCA) occlusion is a rare but potentially disabling cause of stroke. While endovascular treatment is established for acute large vessel occlusion (LVO) stroke, FPCA occlusions were excluded from acute ...

Risk Related Brain Regions Detected with 3D Image FPCA [PDF]

SSRN Electronic Journal, 2015
Risk attitude and perception is re ected in brain reactions during RPID experiments. Given the fMRI data, an important research question is how to detect risk related regions and to investigate the relation between risk preferences and brain activity.

Flow dynamics in acute ischemic stroke due to embolic occlusion of a fetal posterior cerebral artery treated with endovascular thrombectomy - report of two cases

Radiology Case Reports, 2022
The fetal variant of the posterior cerebral artery (fPCA) conserves a major blood flow from the anterior to the posterior cerebral circulation via a strong persistent caudal portion of the embryonic internal carotid artery.
