Four patients with a clinically significant radial artery anomaly

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
The superficial radial artery is an anatomic variant in which the radial artery passes superficial to the tendons of the anatomic snuffbox. Cadaver studies have shown its incidence to be 0.5% to 1%.

Superficial radial artery- a rare variation and its clinical significance

National Journal of Clinical Anatomy, 2014
During routine dissection of upper limb, a variation in the origin of radial artery was observed in a female cadaver of about 60 years. The radial artery is usually a smaller terminal branch of the brachial artery in the forearm. On the right side of the

Anatomic Variation in the Origin and Course of Radial Artery: A Descriptive Cross-Sectional Study

Journal of Nepal Medical Association, 2019
Introduction: The radial artery is commonly originated from the brachial artery in the cubital fossa at the level of the neck of the radius. It is the artery of choice for coronary artery angiography, percutaneous coronary artery intervention ...

Practical identification of NARMAX models using radial basis functions [PDF]

, 1990
A wide class of discrete time non-linear systems can be represented by the non-linear autoregressive moving average model with exogenous inputs or NARMAX model. This paper develops a practical algorithm for identifying NARMAX models based on radial basis

On spherical averages of radial basis functions [PDF]

, 2008
A radial basis function (RBF) has the general form $$s(x)=\sum_{k=1}^{n}a_{k}\phi(x-b_{k}),\quad x\in\mathbb{R}^{d},$$ where the coefficients a 1,…,a n are real numbers, the points, or centres, b 1,…,b n lie in ℝ d , and φ:ℝ d →ℝ is a radially symmetric

Genetic Versus Environmental Influence on Radial Variation in Myracrodruon urundeuva Wood

Floresta e Ambiente, 2017
We hypothesized that Myracrodruon urundeuva trees of two provenances with different genotypes would present variations influenced by their origin terms of anatomy and specific gravity when planted in an environment different from their seed origin, but ...
