Fetal-Type Variants of the Posterior Cerebral Artery and Concurrent Infarction in the Major Arterial Territories of the Cerebral Hemisphere

Journal of Investigative Medicine High Impact Case Reports, 2016
Fetal-type or fetal posterior cerebral artery (FPCA) is a variant of cerebrovascular anatomy in which the distal posterior cerebral artery (PCA) territory is perfused by a branch of the internal carotid artery (ICA).

The posterior cortical axis as an alternative reference for femoral component placement in total knee arthroplasty

Journal of Orthopaedic Surgery and Research, 2020
Background Although several reference axes have been established for determining femoral rotational alignment during total knee arthroplasty (TKA), the most accurate axis is undetermined.

Concurrent infarctions in the territories of internal carotid artery and posterior cerebral artery in the background of foetal type variant of posterior cerebral artery

Asian Journal of Internal Medicine
A 46-year-old woman admitted with a headache and syncopal episode to the hospital, was found to have an upper-motor-neuron type weakness on the left side of the body on waking up the following day.

A new FPCA-based fast segmentation method for color images [PDF]

Proceedings of the Fourth IEEE International Symposium on Signal Processing and Information Technology, 2004., 2005
Fuzzy objective function-based clustering methods are proved to be fast tools for classification and segmentation purposes. Unfortunately, most of the available fuzzy clustering methods are using the spherical or ellipsoidal distances, which are proved to result in spurious clusters, when working on color data.

Phase Correcting Miniature Convoluted FSS in a Fabry–Perot Cavity Antenna

IEEE Access
This paper presents various designs for enhancing the radiation performance of a conventional Fabry-Perot cavity antenna (FPCA) by improving its aperture phase distribution using miniaturised convoluted frequency selective surfaces (FSS). The FSS behaves

Improvements for Free [PDF]

Electronic Proceedings in Theoretical Computer Science, 2011
"Theorems for Free!" (Wadler, FPCA 1989) is a slogan for a technique that allows to derive statements about functions just from their types. So far, the statements considered have always had a purely extensional flavor: statements relating the value ...

The Distributional Effects of Economic Uncertainty*

International Economic Review, EarlyView.
ABSTRACT We study the distributional implications of uncertainty shocks by developing a model that links macroeconomic aggregates to the US distribution of earnings and consumption. Our findings suggest that the fraction of low‐earning workers decreases initially, while the share of households reporting low consumption increases.
