The modified Allen's test is also performed prior to heart bypass surgery. The radial artery is occasionally used as a conduit for bypass surgery, and its patency lasts longer in comparison to the saphenous veins. Prior to heart bypass surgery, the test is performed to assess the suitability of the radial artery to be used as a conduit.

Watzke-Allen test is a test used in the diagnosis of a macular hole. It is a subjective test based on photoreceptor displacement. [1] Test can be used to differentiate full thickness macular hole from other similar conditions and also to assess retinal function after surgical closure of the hole. [2] [3]
The original scoring system was developed before the invention of pulse oximetry and used the patient's colouration as a surrogate marker of their oxygenation status. A modified Aldrete scoring system was described in 1995 [2] which replaces the assessment of skin colouration with the use of pulse oximetry to measure SpO 2.
The modified Allan variance (MVAR), [2] also known as mod σ y 2 (τ), is a variable bandwidth modified variant of Allan variance, a measurement of frequency stability in clocks, oscillators and amplifiers. Its main advantage relative to Allan variance is its ability to separate white phase noise from flicker phase noise.
The New York Heart Association (NYHA) Functional Classification provides a simple way of classifying the extent of heart failure.It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regard to normal breathing and varying degrees in shortness of breath and/or angina.
Alan Mann Racing was a British motor racing team organised by Alan Mann (22 August 1936 – 21 March 2012), who was a part-time racing driver and team manager. The team ran a substantial part of the Ford works racing effort in Europe from 1964 to 1969, [1] when it ceased operations.
The explicit midpoint method is sometimes also known as the modified Euler method, [1] the implicit method is the most simple collocation method, and, applied to Hamiltonian dynamics, a symplectic integrator. Note that the modified Euler method can refer to Heun's method, [2] for further clarity see List of Runge–Kutta methods.
