What is Cubic: Definition and 427 Discussions

CUBIC (abbreviation for “clear, unobstructed brain/body imaging cocktails and computational analysis) is a histology method that allows tissues to be transparent (process called “tissue clearing”). As a result it makes investigation of large biological samples with microscopy easier and faster.
The method was published in 2014 by Etsuo A. Susaki and Hiroki R. Ueda, primarily for use in neurobiology research of brains from model organisms like rodents or small primates. But in upcoming years there were other works published, using CUBIC method on other tissues like lymph nodes or mammary glands. CUBIC can be also combined with CLARITY-based tissue clearing methods.

    Proving Cubic Equation Theta & a,b

    Hai, I have a question solving a cubic equation. I have a function y=ax*x*x+bx*x. I want to get a solution for the value of a and b. From reference, I found that a=(xtan(Theta)-2y)/(x*x*x) and b=(3y-xtan(Theta))/(x*x) [Theta] is an angle or tangent of each point x along a cubic curve or...

    Solving a cubic (or rather simplifying a real root in complex form)

    The determinate of the following 3x3 matrix 1-y, 2 , 3 2 , 4-y, 5 3 , 5 , 7-y gives a cubic that simplifies to, y^3 - 12*y^2 + y + 1 = 0. Now, apparently the teacher picked random numbers for the original matrix, making the problem delve into other realms of mathematics...

    Crystal Planes, Miller Indices: Cubic Lattice

    Just when I thought I understood the concept of planes and miller indices, I got stuck on a 'test your understanding' Q in my book. I can't understand that there can be two or more (110) planes in a crystal lattice? I thought there can be only one such plane. The question asks me to find the...

    Is the Discriminant of a Cubic Always Negative When There are Real Roots?

    On mathworld's discussion of the cubic formula he has that "determining which roots are real and which are complex can be accomplished by noting that if the polynomial discriminant D > 0, one root is real and two are complex conjugates; if D = 0, all roots are real and at least two are...

    What's the solution of Cubic and biquadratic polynomial?

    It's very easy to solve the equation for x: ax^2 + bx + c = 0 The law for the answer will be (-b+-sqrt(delta))/2a OK, what if i want to solve: ax^3 + bx^2 + cx + d = 0 ax^4 + bx^3 + cx^2 + dx + e = 0 a,b,c,d,e constants, How I'm going to solve this for x? isn't there a general law?
