Right-Hemisphere (Spatial?) Acalculia and the Influence of Neglect

open access: yesFrontiers in Human Neuroscience, 2014
The present study aimed at exploring basic number and calculation abilities in right-hemisphere damaged patients (RHD), focusing primarily on one-digit orally presented tasks, which do not require explicit visuo-spatial abilities.

Preliminary study on internal carotid artery perfusion imaging and clinical application based on digital subtraction angiography

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2022
Background DSA is an irreplaceable diagnostic method for cerebral vascular disease. It is sensitive to intracranial macrovascular disease, but not to distal blood perfusion. In order to quantitatively assess the perfusion area of the feeding artery, this

Appearance of the canine meninges in subtraction magnetic resonance images [PDF]

open access: yes, 2014
The canine meninges are not visible as discrete structures in noncontrast magnetic resonance (MR) images, and are incompletely visualized in T1‐weighted, postgadolinium images, reportedly appearing as short, thin curvilinear segments with minimal ...

Enhancing quantum entanglement for continuous variables by a coherent superposition of photon subtraction and addition [PDF]

open access: yes, 2011
We investigate how the entanglement properties of a two-mode state can be improved by performing a coherent superposition operation of photon subtraction and addition, proposed by Lee and Nha [Phys. Rev. A 82, 053812 (2010)], on each mode.
