A Comprehensive Study of the Anatomical Variations of the Circle of Willis in Adult Human Brains [PDF]

Journal of Clinical and Diagnostic Research, 2013
Background: Cerebrovascular diseases such as stroke, aneurysms and arterio-venous malformations are very much prevalent in our country. Circle of Willis, as an anastomotic polygon at the base of the brain forms an important collateral network to ...

Order-of-magnitude speedup for steady states and traveling waves via Stokes preconditioning in Channelflow and Openpipeflow

, 2018
Steady states and traveling waves play a fundamental role in understanding hydrodynamic problems. Even when unstable, these states provide the bifurcation-theoretic explanation for the origin of the observed states. In turbulent wall-bounded shear flows,

Configuration of Circle of Willis and Its Clinical Significance

Journal of Bahria University Medical and Dental College, 2018
In occlusive vascular brain diseases, the structure of the circle of Willis is of immense importance. A high percentage of variations have been reported in the arteries forming circle of Willis. These have profound clinical implications.

WTAP affects intracranial aneurysm progression by regulating m6A methylation modification

Open Medicine, 2023
Intracranial aneurysm (IA) is a type of cerebrovascular disease that mainly occurs in the circle of Willis. Abnormalities in RNA methylation at the N6-methyladenosine (m6A) site have been associated with numerous types of human diseases.

Acceleration of generalized hypergeometric functions through precise remainder asymptotics

, 2011
We express the asymptotics of the remainders of the partial sums {s_n} of the generalized hypergeometric function q+1_F_q through an inverse power series z^n n^l \sum_k c_k/n^k, where the exponent l and the asymptotic coefficients {c_k} may be ...
