Find the gradient of the normal to the curve y = x^2 at the point (2, 4). If f (x, y) = x^2 + 9 y^2, use the gradient vector nabla f (-5,10) to find the tangent line to the level curve ...
To select a slice in 2-D imaging, a gradient in the magnetic field is produced in a direction that is normal to the slice giving the spins unique Larmor frequencies in this direction. An RF pulse with a prescribed bandwidth excites only spins within a particular range of Larmor frequencies ...
英文导数题The curve y=ax^2+bx+c passes through the point A(-2,0) abd B(3,20).The slope of the normal at A is 1 and the gradient of the tangent at B is 9.Find the values of a,b and c.

Article GLUCOSE GRADIENT OF MATERNAL VEIN-UMBILICAL VEIN AND UMBILICAL VEIN-UMBILICAL ARTERY IN NORMAL-GROWTH AND GROWTH-RETARDED TERM FETUSES was published on January 1, 1990 in the journal Journal of Perinatal Medicine (volume 18, issue s1).
Patients with low LVEF, “classical” low-flow, low-gradient (LF-LG) AS (5% to 10% of the AS population) generally have a dilated LV cavity with markedly depressed myocardial systolic function and reduced LV outflow. Normal LVEF, “paradoxical” LF-LG AS (10% to 25% of AS population)...
Mean Gradient AC/A for patients with a normal Clinical AC/A was 2:1, below the range traditionally thought of as normal. Mean Gradient AC/A for patients with a high Clinical AC/A was 5:1. Forty-four percent of those with a high Clinical AC/A had a normal or low Gradient AC/A, ...

Hedgehog (Hh) signalling is important in development, stem cell biology and disease. In a variety of tissues, Hh acts as a morphogen to regulate growth and cell fate specification. Several hypotheses have been proposed to explain morphogen movement, one
of inter- and intra-GSC transcriptional heterogeneity that could not be fully explained by DNA somatic alterations. Instead, we found that GSCs mapped along a transcriptional gradient spanning two cellular states reminiscent of normal neural development and inflammatory wound response. Genome-wide CRISPR...
